The technical idea of the present invention is: the whole machine includes modules such as a U-shaped claw clamping mechanism, a thermal printer, a double-stroke suction cup packing mechanism, a box cover feeding mechanism, a double conveyor belt material conveying mechanism, and a sealing machine core.

The U-shaped claw clamping mechanism is mainly composed of a sliding table cylinder, a U-shaped claw body, and a double-rod cylinder. In the process of packing and sealing, the main body of the U-shaped claw is first pushed by the double-rod cylinder, and the packaging box is clamped by using the connecting rod movement, and then the cylinder of the slide table moves to drive the main body of the U-shaped claw and the packaging box clamped by it to complete the station. switch. After arriving at the corresponding labeling station, the slider of the U-shaped claw body can be pushed out by the double-rod cylinder, which drives the U-shaped claw to stretch out quickly, and quickly retracts after a short stay. Repeat twice to complete the labeling action with the thermal printer. . After the labeling is completed, the double-rod cylinder is retracted, and the connecting rod mechanism is used to drive the main body of the U-shaped claw to loosen, releasing the packaging box, so that the subsequent station can complete the boxing action. This mechanism completes the station switching of the packaging box, and can complete the labeling function with the thermal printer. It integrates multiple functions such as separation, clamping, positioning and labeling. It greatly improves the space utilization rate, and the cylinder drives the mechanical structure. Clamping makes positioning more reliable, and multi-station switching also improves the efficiency of the whole machine.

The double-stroke suction cup packing mechanism is mainly composed of two double-rod cylinders, a sliding platform and two suction cups. During the packing process, the first double-rod cylinder is quickly lowered, and the suction cup is slightly squeezed and tightly attached to the packaging box. The vacuum generator starts to make the suction cup absorb the packaging box, and the corresponding U-shaped claw releases the packaging box. , With the suction force of the two suction cups, the packaging box is stably sucked up, and the second double-rod cylinder slowly descends, driving the suction cup at the head of the cylinder to descend at the same time, and it is smoothly loaded into the foam box. After being placed in the foam box, the vacuum generator is turned off, the suction cup loses its suction, and the second double-rod cylinder is quickly retracted, followed by the first double-rod cylinder. Finish packing of a box. This mechanism is the executive module that connects the U-shaped claw clamping mechanism and the double synchronous belt material conveying mechanism. It is responsible for putting the labeled packaging boxes into the foam box stably. It is the starting module of the whole small fruit boxing and sealing machine. . The mechanism cooperates with the U-shaped claw clamping mechanism to complete the packing process from the packaging box to the foam box, and realizes the core function of integration from the box to the box. The main advantage is that the packing process is efficient and stable, and at the same time avoids packing Box drop, vibration, effectively reduce fruit damage.

The automatic feeding mechanism of the foam box cover is mainly composed of an I-shaped plate, an L-shaped plate, a cylinder, a connecting rod, and a fixed short shaft. According to the shape characteristics of the foam box cover, the mechanism adopts a self-designed space multi-link mechanism. The connecting rod mechanism used forms a rectangle similar to the shape of the rectangular foam box cover in the top view plane, and a baffle plate that can be used to block the foam box cover is designed at the junction of the connecting rods to store the foam box that does not need to be fed. The role of the cover. In one of the limit positions of the link mechanism, the bottom foam box cover is blocked by the I-shaped baffle and cannot fall off, and the upper L-shaped baffle does not have a blocking effect. And move to another limit position of connecting rod mechanism, I type baffle plate rotates away and no longer blocks the lowermost case cover, and this case cover feeds. At the same time, the linked upper L-shaped baffle rotates and moves to block the penultimate layer of the box cover. The mechanism cleverly utilizes the movement trajectory of the multi-links in the space to realize the function of feeding the bottom foam box cover and isolating other box covers. The structure is simplified, the action is convenient, and the packaging efficiency is improved.

The double conveyor belt material conveying mechanism is mainly composed of two parts: the packing timing belt and the sealing timing belt. In the process of packing and sealing, the foam box is first driven by the packing synchronous belt to the packing station, that is, under the U-shaped claw, the packing box is released by the U-shaped claw, and the packing is completed by the double-stroke suction cup packing mechanism. . The boxing timing belt moves again, and the second boxing is completed on the same principle as above. After the packing is completed, the foam box is pushed out by the packing synchronous belt until the box is completely positioned on the platform on the sealing synchronous belt. At this time, the cover box function can be completed by cooperating with the foam box cover feeding mechanism above the platform. After the foam box cover is covered, the sealing timing belt moves to drive the platform into the sealing machine core to complete the sealing. This mechanism is the connecting mechanism of all executive stations, responsible for the transportation of foam boxes, reversing and switching between stations, and runs through the entire movement process of the small fruit packing and sealing machine. This mechanism completes the position switching of the foam box, cooperates with the double-stroke suction cup packing mechanism and the sealing machine core mechanism to realize the packing and sealing functions, and is mainly responsible for the transportation, reversing and station switching of the foam box. It effectively shortens the normal pipeline.

The beneficial effects of the present invention are mainly manifested in: higher work efficiency and lower labor cost.

Figure 2 is a partially enlarged view of the small fruit packing and sealing machine, and Figure 3 is a partially enlarged side view of the small fruit packing and sealing machine, which is mainly represented by a U-shaped claw clamping mechanism 40 . The specific mechanisms and principles of each institution are as follows:

Figure 4 shows the structural diagram of the material conveying mechanism with double conveyor belts. The two synchronous belts are controlled by two stepping motors respectively. In the initial state, the foam box 906 is at the leftmost position, and the packing synchronous belt 909 starts to rotate, driving the foam box 906 to move to the right until the front end of the foam box 906 is located directly under the U-shaped claw, the U-shaped claw is loosened, and the double The stroke suction cup packing mechanism completes the first box packing; in the same way, the packing synchronous belt 909 continues to move forward for a short distance, and the U-shaped claw and the double-stroke suction cup packing mechanism cooperate to complete the second box packing.

After the sealing is completed, take out the finished foam box that has been packed.

Figure 5 and Figure 6 show the structural diagram of the double-stroke suction cup packing mechanism. Support 1009 and double-rod cylinder 1008 are fixed. The slide block 1005, the vertical slide rail 1006 and the buckle 1007 are combined into a sliding mechanism, which can drive the secondary cylinder seat 1004 and the secondary double-rod cylinder 1003 to slide down together to complete the first stroke movement. The double-layer suction cup 1001 is fixed on the double-rod cylinder 1003 through the suction cup seat 1002, and moves up and down along with the expansion and contraction of the cylinder. In the initial state, both the first-stage double-rod cylinder 1008 and the second-stage double-rod cylinder 1003 remain retracted. First, the first-stage double-rod cylinder 1008 starts to move downward rapidly, and the sliding mechanism composed of the slider 1005 , the vertical slide rail 1006 and the buckle 1007 drives the entire second-stage double-rod cylinder 1003 to descend. After the stroke is over, the double-layer suction cups 1001 are tightly attached to the upper surface of the packaging box, the vacuum generator is activated, the suction cups absorb the packaging box, the U-shaped claws are released, and only the two suction cups are used to absorb the entire packaging box. Then, the secondary double-rod cylinder 1003 slowly stretches out, driving the double-layer suction cups 1001 on the head of the cylinder to descend simultaneously, and stably pack into the foam box. After the stroke ends, the vacuum generator is closed, the double-layer suction cup 1001 loses its suction, the second-stage double-rod cylinder 1003 quickly retracts, and then the first-stage double-rod cylinder 1008 quickly retracts, driving the second-stage cylinder seat 1004 and the second-stage double-rod cylinder 1003 to rise together , return to the initial state, and wait for the U-shaped claw to hold the next box in place. The above process ends the packing of a packing box.

Figures 7 to 10 show the structural diagrams of the U-shaped claw clamping mechanism. In the initial state, the main body of the U-shaped claw is located at the far left end, the clamping cylinder 410 is in an extended state, and the main body of the U-shaped claw is in a loosened state. The clamping cylinder 410 is fixed to the sliding seat 411, and is connected to the side plate 402 through the joint bearing 412, and the side plate 402 is connected to the additional plate 404 through the angle code. The slide rail 413 and the slide block 403 are fixed on the side plate 402 in cooperation. The slide table cylinder 409 is fixed with the support plate 408, so that the slide table cylinder 409 drives the movement of the whole U-shaped claw main body. When the packaging box 401 enters the main body of the U-shaped claw, the clamping cylinder 410 is retracted, and the sliding seat 411 is driven to retract. The sliding seat 411 realizes that the side plate 402 is folded through the joint bearing 412, and the main body of the U-shaped claw becomes a clamping state. After clamping, the sliding table cylinder 409 drives the entire U-shaped claw body and the packaging box to move to the left. After reaching the leftmost end, another double-rod cylinder pushes the seat plate 407, and the U-shaped jaw is realized by the free movement of the slider 403 on the slide rail 413. The main body of the type claw clamps the packaging box and protrudes, and can cooperate with the thermal printer to complete the function of pasting labels. After the slide block 403 is pushed out, it stays for a short time, and then withdraws quickly, repeating twice, so as to ensure that the label is tightly attached to the upper surface and the side of the packaging box. After the labeling is completed, the clamping cylinder 410 is stretched out, driving the sliding seat 411 to stretch out, the side plate 402 is opened through the joint bearing 412, the main body of the U-shaped claw becomes loose, and the packaging box is released, so that the subsequent station can complete the packaging. box, sealing box.

As shown in Figures 11 to 14, the main part of the space multi-link foam box cover feeding mechanism is three parallel four-bar mechanisms skillfully distributed according to the shape of the foam box cover and connected in series through the short axis and the baffle. For an active parallel multi-link mechanism, the piston rod of the tank cover feeding cylinder 505 is connected with the upper L-shaped baffle plate 507 through a joint bearing 503 . The upper space L-shaped baffle 507 at the same corner is connected with the space lower I-shaped baffle 501 through the fixed short axis 506 . In addition, the L-shaped baffle 507 at two adjacent corners of the rectangle is connected to the I-shaped baffle 501 through an additional short shaft 502 and a connecting rod 508 that is fixedly connected to joint bearings 503 at both ends. The L-shaped baffle plate 507 in the upper space and the I-shaped baffle plate 501 in the lower space are coaxially connected and staggered by 90 degrees to fix and position the three parallel four-bar devices in proper positions. During work, the case cover feeding cylinder 505 drives the active L-shaped plate 507 to rotate, and drives the lower floor I-shaped plate 501 to rotate. Through the transmission of the parallel four-bar mechanism connected with the I-shaped plate 501 or the L-shaped plate 507, all the L-shaped plates 507 located on the upper floor and all the I-shaped plates 501 located on the lower floor are rotated at a certain angle in the same direction at the same time. As shown in Figure 13, the lower I-type baffle plate 501 moves away from the blocking position, and the lowermost foam box cover feeds. The L-shaped baffle plate 507 on the upper floor all reaches the blocking position, blocking the feeding of the penultimate layer and the top foam box cover. The piston rod return stroke of box cover feeding cylinder 505 drives the connected L-shaped plate 507 to reversely rotate a certain angle and get back to the original position. Similar to the working stroke action described in the previous paragraph, all the L-shaped baffles 507 and I-shaped baffles 501 are rotated through a fixed angle and returned to their original positions through three parallel four-bar mechanisms in series. As shown in Figure 14, the lower I-type baffle plate 501 returns to the blocking position, and the lowermost layer and the upper foam box cover are blocked and cannot fall and feed. The upper L-shaped baffle plate 507 moves away from the blocking position. Through the rapid drive of the box cover feeding cylinder 505, the space multi-link mechanism moves quickly, and it is convenient to achieve the isolation of a single feeding of the foam box cover, and the foam box cover is completely fed and lowered to the feeding preparation position. Switching between two working states , Realize the function of sequential feeding and interval feeding of the foam box cover.
