Description

Adsorption roller

This creation relates to a roller (or drum) structure used in a roll-to-roll transfer production process, and particularly to an revealer of an innovative structural type of an adsorption roller.

For some materials with flexible characteristics (such as flexible displays), the use of rollers as the roll-up transmission production mode in the manufacturing process has become an important form of process equipment development.

In the aforementioned rolling conveying production process using rollers, in view of the deviations and jumps of the conveyed materials relative to the rollers, which will relatively affect the defective rate of the finished product, some related industries have subsequently developed The roller structure of the pressure adsorption function is considered as the response.

In the conventional structural design of the aforementioned roller with negative pressure adsorption function, the adsorption area usually includes the entire peripheral surface of the roller. However, because the actual contact area between the transferred material and the roller does not exceed half a circle at most In this way, during the operation of the conventional scroll wheel, half of the suction may be rendered redundant and useless, and there are problems and disadvantages of wasted energy. This is an important technical issue worthy of further attention and consideration by the relevant industries.

The main purpose of this creation is to provide an adsorption roller. The technical problem it wants to solve is to make an innovative breakthrough with the goal of how to develop a new type of adsorption roller structure with more ideal practicability.

Based on the foregoing purpose, the present invention provides an adsorption type roller, which includes: a fixed inner shaft, which is arranged along a central axis in a fixed and non-rotatable state, the fixed inner shaft has a suction end, and the interior of the fixed inner shaft is hollow. An inhalation guide channel is defined, one end of the inhalation guide channel is in communication with the inhalation terminal, and a plurality of through holes are provided on the peripheral wall of the fixed inner shaft, and the inner ends of the inhalation holes and the inhalation guide channel are alternately connected. Relationship; a rotating outer tube is arranged coaxially with the fixed inner shaft, and the rotating outer tube is arranged at the outer peripheral space of the fixed inner shaft through two end seals, so that the rotating outer tube can be stressed relative to the fixed inner shaft To drive the state of rotation, the wall ring of the rotating outer cylinder is provided with a plurality of spaced-apart suction holes, and a circular space is defined between the rotating outer cylinder and the fixed inner shaft; two partition plates are arranged on the fixed inner shaft. The peripheral walls are located at different positions and are located in the annular space. Each partition includes a positioning edge provided on the fixed inner shaft peripheral wall and a protruding edge corresponding to the inner wall of the rotating outer cylinder. Set angle between 180 ° System, and thereby form a gas-conducting chamber relatively defined between the two partitions, and connect the air-conducting chamber with the outer end of a plurality of air-through holes provided on the peripheral wall of the fixed inner shaft; two elastic force blocks are arranged in The protruding edges of the two partitions, and each of the elastic abutment blocks are elastically fed and contracted, and constantly abut against the inner wall of the rotating outer cylinder.

This innovative and unique structural form and technical characteristics make this creation contrast with the previous technology. When the negative pressure suction is generated in the suction guide channel of the fixed inner shaft, only the rotation outside the corresponding range of the air guide chamber is generated. The suction hole provided in the cylinder generates suction, thereby having the function of limiting the suction range, thereby achieving the advantage of avoiding waste of energy and practical progress; and through the setting of the elastic force against the block, the partition plate is convex during the rotation of the rotating outer cylinder. An airtight fitting relationship can always be maintained between the extended edge and the inner wall of the rotating outer cylinder to ensure that the range of suction is limited.

Progressive.

Another purpose of this creation is to cover the outer wall of the rotating outer cylinder with a fine mesh layer. The fine mesh layer has another technical feature between 80 and 105 mesh to make use of the fine mesh. The mesh layer has the characteristics of a fine mesh. When a negative pressure suction is generated by the suction hole of the rotating outer cylinder, a mesh-like breathable partition can be formed at the outer end of the suction hole, thereby reducing the advantages of the transmission material being partially sucked. Practical and progressive.

Another purpose of this creation is to set a limit frame by sealing the ends. The limit frame is formed with an inwardly extending ring frame edge between the edge of the ring frame and the outer surface of the fine mesh layer. Relatively defined to form a ring-shaped clamping gap, and an auxiliary positioning ring lining is set in the plug set in the ring-shaped clamping slot to assist in pressing and positioning another technical feature of the side portion of the fine mesh layer, so as to effectively prevent the side portion The advantages and practical progress of warping deformation.
