The mode control is particularly suitable for transverse pavement of a small number of flaking.

The screening roller 1 is also designed, the core component for removing the bent shavings is a plurality of screening rollers 1 which are sequentially arranged, and the screening rollers 1 form a continuous operation removing system. The arrangement of each screening roller 1 ensures that materials can continuously and uniformly pass through the whole screening process, and the screening rollers 1 are driven through chains, so that the screening device is simple in structure and not easy to damage. Each picking roller 1 is provided with a plurality of picking sheets 2, and the picking sheets 2 are arranged along the axial direction of the picking roller 1 to form a series of orderly picking intervals 201. The picking sheets 2 on the adjacent picking rollers 1 are staggered, and the picking sheets 2 and the corresponding picking sheets 2 on the adjacent same picking roller 1 form a picking interval 201 together, which is a key screening area. Each pick material tab 2 is provided with one or more pick material notches 202, which, when present, are arranged circumferentially around the pick material tab 2, in order to precisely "catch" and reject curved or non-conforming shavings. The principle of removing curved shavings, during operation, the raw material shavings sheet passes through the respective pick gap 201 as the pick roller 1 rotates.

Further, the chassis 3 has a feed port 301, and the feed port 301 is located above the nail roller 4 and the dispersion roller 5.

In this embodiment, a material inlet is designed, and the material inlet 301 is skillfully designed at the top of the chassis 3, and is located just above the nail roller 4 and the dispersion roller 5. The layout fully utilizes the gravity effect, so that shavings can directly fall into from the upper part, the shavings start to be uniformly distributed through preliminary treatment of the nail roller 4 and the throwing roller 5, the distribution efficiency is improved, the design simplifies the material guiding flow, reduces the complex guiding links of the materials before entering the treatment unit, ensures that the materials can enter the working state more quickly, and improves the overall production efficiency and the material treatment speed. Because the material freely falls from the upper part and enters, the cooperation of the nail roller 4 and the throwing roller 5 can naturally promote the material to start to disperse in the falling process, thereby being beneficial to the accurate regulation and control of the subsequent transverse and longitudinal directional rollers 7 and further ensuring the transverse uniformity of the cloth. The upper position design of the feeding port 301 is convenient for operators or an automatic feeding system to add materials, so that the operation difficulty is reduced, the time and labor cost of manual intervention are reduced, and the material supplementing process is more visual and controllable. The design of the feed inlet 301 is also beneficial to maintenance and cleaning of equipment, the position of the feed inlet 301 is higher, dust and impurities in the working environment can be reduced to directly fall into the equipment, the cleanliness of the inside of the machine is maintained, and the service life of the equipment is prolonged.

Further, the plurality of spike rollers 4 and the plurality of dispersion rollers 5 are arranged obliquely along a straight line.

In this embodiment, the inclined arrangement of the spike roller 4 and the dispersing roller 5 is designed so that the material is not only subject to the dispersion of rotation but also to a natural sliding tendency due to the inclination angle when passing through these rollers. The gravity-assisted material can be used for assisting the downward movement of the material, so that the material passing speed is accelerated, meanwhile, the material is further scattered in the sliding process, and the dispersion uniformity of the material is improved. The oblique arrangement may further include a plurality of arc-shaped blades 601 circumferentially arranged on the transverse orientation roller 6, and a transverse trough 602 is formed between two adjacent arc-shaped blades 601, and the length direction of the transverse trough 602 is parallel to the axial direction of the transverse orientation roller 6.

Further, the transverse orientation roller 6 is provided with a plurality of arc-shaped blades 601 which are circumferentially arranged, a transverse trough 602 is formed between two adjacent arc-shaped blades 601, and the length direction of the transverse trough 602 is parallel to the axial direction of the transverse orientation roller 6.

In this embodiment, the plurality of arc-shaped blades 601 circumferentially arranged on the transverse orientation roller 6 not only increases the surface area in contact with the material, but also effectively guides and disperses the material transversely by the special shape of the blades. When each blade rotates, uniform acting force can be applied to passing materials, and uniform movement and uniform distribution of the materials in the transverse direction are promoted. A transverse trough 602 is formed between two adjacent arcuate blades 601, the length of which is maintained parallel to the axial direction of the transverse orientation roller 6. The design aims at providing a definite transverse moving channel for materials, ensuring that the materials can be accurately guided along the direction of the trough when passing through, avoiding random distribution of the materials in the transverse moving process, and improving transverse uniformity of the cloth. By adjusting the rotational speed of the transverse directional rollers 6 and the shape and spacing of the blades, the flow speed and distribution of the material in the transverse trough 602 can be further precisely controlled, which is critical to achieving a highly uniform distribution. Especially when handling the material that needs meticulous mating formation such as shaving board wood shavings, can show the quality and the uniformity that promote the layer of mating formation. The design of the transverse trough 602 helps to reduce accumulation or blockage of materials in the conveying process, ensures continuity and stability of material flow, and avoids uneven distribution caused by local accumulation. In summary, by arranging the arc-shaped blades 601 which are circumferentially arranged and the transverse trough 602 which is formed on the transverse directional roller 6, the surface layer paving equipment not only enhances the precise control and uniform distribution of materials in the transverse direction, but also improves the overall treatment efficiency and the product quality, and is one of key designs for realizing high-quality surface layer paving.

Further, a guide plate 12 is included, and the guide plate 12 is obliquely arranged below the staple roll 4 and above the transverse orientation roll 6.

In the present embodiment, the guide plate 12 is designed to be inclined, and is installed directly under the staple roller 4 and above the lateral orientation roller 6. This inclined arrangement aims to more efficiently guide and control the flow direction of the material initially treated by the spike roller 4 by using the principle of physical guiding, ensuring that the material has moved smoothly in a predetermined path before entering the transversely oriented roller 6. Through adjusting the inclination of deflector 12, can accurate control material in the ascending whereabouts route and the speed of vertical direction, help reducing the bounce and the uneven dispersion of material in whereabouts in-process for the material keeps more unanimous and concentrated state when getting into the horizontal directional roller 6 of next level processing unit, thereby promotes the homogeneity of following mating formation. The inclined design of the guide plate 12 can also effectively avoid accumulation of materials in the falling process or blockage at the inlet of the processing unit, ensure the smoothness of continuous operation, reduce the time of shutdown cleaning and improve the overall production efficiency. The existence of the guide plate 12, combined with the inclination angle and the position thereof, can perform preliminary directional spreading on the material, provides a good starting point for fine spreading of the subsequent transverse directional roller 6, and ensures the transverse uniformity and the overall flatness of the final spreading layer. In summary, the inclined arrangement of the guide plate 12 plays a key role in the surface layer paving device, not only optimizes the flow direction control of the material, but also further improves the efficiency of material processing and the uniformity of cloth, and is one of key design elements for realizing high-quality surface layer paving.

Further, the lower end of the guide plate 12 faces the transverse trough 602.

In this embodiment the lower end of the guide plate 12 is directed towards the transverse trough 602, which design ensures that the material processed from the spike roller 4 slides along a well-defined and controlled path towards the transverse orientation roller 6. This direct directionality improves the accuracy of the material flow direction, reducing unwanted scattering or deviation, and allowing the material to enter the transverse trough 602 more intensively and orderly. By aligning the lower end of the guide plate 12 to the transverse trough 602, the material can be better evenly distributed along the trough during the sliding down process, avoiding accumulation or vacancy before entering the transverse orientation roller 6, and further ensuring the uniformity of transverse pavement. This is important to improve the flatness and structural strength of the finished particle board. The design can also promote smooth flow of materials in the guiding process, reduce friction and retardation, ensure that the materials keep good dynamic state in the flow, be favorable for efficient operation of a subsequent processing unit and promote overall production efficiency and throughput capacity of equipment. The precise directional design of the guide plate 12 simplifies maintenance and adjustment work of the equipment, and when the material flow direction or the treatment efficiency needs to be adjusted, operators only need to simply adjust the angle or the position of the guide plate 12, so that different production requirements or material characteristics can be quickly adapted. In summary, the design of the lower end of the guide plate 12 facing the transverse trough 602 not only enhances the directional conveying and uniform distribution of materials, but also improves the overall efficiency and the operation flexibility of the equipment, and is an important component for realizing high-quality and high-efficiency surface layer pavement.

Further, an auxiliary guide plate 8 is also included, the upper end of the auxiliary guide plate 8 is connected with a guide plate 12, and the other end of the auxiliary guide plate is led to a transverse trough 602.

In this embodiment, the upper end of the auxiliary guide plate 8 is connected to the main guide plate 12, while the other end is aligned with the transverse trough 602, forming a continuous and more rigid material guide channel. This double layer guiding design ensures a smoother, more orderly transition of the material from the spike roller 4 to the transversely oriented rollers 6, reducing the deflection or scattering of the material during transport. The presence of the auxiliary guide plate 8 provides an additional guide and constraint for the material, particularly when the material flow is large or finer control is required, and can effectively avoid turbulence or accumulation of the material in high-speed movement, and maintain the consistency and uniformity of the material flow. By the connection of the auxiliary guide plate 8 with the main guide plate 12, the stability of the entire guide structure is enhanced. The method is not only beneficial to reducing the abrasion of the equipment in long-time operation, but also can cope with various emergency conditions possibly occurring in the production process, such as sudden increase of materials or change of texture, and ensures the continuous operation capability and reliability of the equipment. The design of the auxiliary guide plate 8 makes the adjustment of the entire guide system more flexible. If the guiding path of the material is required to be adjusted or the distribution uniformity is optimized, the material distribution can be quickly realized by adjusting the position or the angle of the auxiliary guiding plate 8 without greatly changing the main structure, thereby simplifying the daily maintenance and the work of parameter adjustment. In conclusion, the addition of the auxiliary guide plate 5 remarkably improves the accuracy and the control capability of the surface layer paving equipment in the material guide direction, is a key design supplement for realizing high-efficiency and high-quality transverse uniform distribution, and further optimizes the stability and the efficiency of the whole production flow.

Further, the guide plate comprises a support plate 9, one end of the support plate 9 is arranged at the lower end of the guide plate 5, and the other end of the support plate is arranged at the lower end of the auxiliary guide plate 8.

In this embodiment, the design of the support plate 9 is added to further stabilize the structures of the guide plate 12 and the auxiliary guide plate 8, so as to ensure the stability and durability of the material guiding system, one end of the support plate 9 is fixed at the lower end of the guide plate 12, and the other end is fixed at the lower end of the auxiliary guide plate 8, so that a stable triangular support structure is formed by such design. This not only enhances the rigidity of the guide plate 12 and the auxiliary guide plate 8, prevents deformation or displacement from occurring under long-term operation or material impact, but also ensures a stable operation state of the guide system in high-speed operation. The addition of the supporting plate 9 shares the weight of the materials born by the guide plate 12 and the auxiliary guide plate 8 and the dynamic load in the moving process, and reduces the stress concentration of the two parts, thereby prolonging the service life of the whole guide system and improving the durability and the reliability of the equipment. The structural design of the support plate 9 is convenient for installation and adjustment, and when the guide system needs to be maintained or adjusted, the support plate 9 serves as a unified support platform, so that the operation flow can be simplified, and the positions or angles of the guide plate 12 and the auxiliary guide plate 8 can be adjusted more easily and accurately. The existence of the supporting plate 9 can also play a role in guiding and regulating the material flow path, so that the material can be smoothly transited into the transverse trough 602 after passing through the guide plate 12 and the auxiliary guide plate 8, and the uniformity and the efficiency of the material flow are further improved. In sum, the addition of the supporting plate 9 not only stabilizes the physical structure of the guiding system, but also indirectly optimizes the guiding effect of the materials and the paving uniformity by improving the overall stability and durability of the equipment, and is an important design supplement for improving the comprehensive performance of the surface paving equipment.

Further, the longitudinal direction roller 7 has a longitudinal direction plate 701, and the longitudinal direction plate 701 is circular.

In this embodiment, longitudinally oriented tabs 701 on longitudinally oriented rollers 7 provide unique advantages over conventional planar or non-circular designs. The round design means that no matter from which angle the material contacts the orientation piece, relatively even driving force can be obtained, the material can be smoothly moved in the longitudinal direction, the resistance difference caused by the shape is reduced, and the uniformity in the paving process is ensured. When the longitudinal orientation piece rotates, the edge of the longitudinal orientation piece is in smooth transition, so that the possibility of clamping or clamping materials is reduced, the continuous pushing of the materials forward is facilitated, the accumulation and the generation of gaps are avoided, and the continuity and the stability of the material flow are ensured. Since the longitudinal direction plates 701 can uniformly contact and guide the material while rotating, this helps to achieve more accurate longitudinal distribution during the paving process, and particularly, can ensure the uniformity of the paving layer and improve the quality of the final product when a large amount or fine material is handled.
