AI Technical Summary
In existing technologies, when cutting ultrathin flexible materials, excessively large spacing between support rollers affects the flatness of the film, and it is difficult for the cutting wheel to avoid them, resulting in uneven cuts.
The feed roller adopts a three-section structure, including two end half rollers and an intermediate roller. The intermediate roller is slidably connected to the mandrel and fixed by locking bolts. The intermediate roller is provided with clearance grooves and inserts. The position of the clearance grooves is adjusted to match the cutting wheel to ensure the contact line between the cutting wheel and the film.
This technology achieves effective contact between the cutting wheel and the film when cutting ultra-thin flexible materials, keeping the cut smooth, avoiding film stretching and deformation, and improving cutting quality.

Abstract
Description
TECHNICAL FIELD
[0001] The utility model belongs to electronic adhesive tape processing technical field relates to a kind of material feeding roller structure on adhesive tape cutting line. BACKGROUND
[0002] After the online processing of electronic adhesive tape, it is cut according to needs, and after forming the specified width, it is wound. During online cutting, in order to ensure that the adhesive tape is flat, a plurality of traction rollers are generally used for support. In the existing mode, only blades are suitable for cutting (the blades are inserted in the gap between adjacent rollers). The blade cutting is suitable for cutting thicker films. When cutting ultra-thin flexible materials, a cutter wheel is used for rotary cutting (the film is pulled and moved, and the cutter wheel is rotated) to avoid deformation of the film caused by pulling and stretching, resulting in uneven film breakage. However, when using the cutter wheel to cut the film, the existing support rollers need to be spaced apart at a relatively large distance, otherwise the cutter wheel cannot be avoided well. However, if the distance between the support rollers is too large, it will affect the flat traction of the film. SUMMARY
[0003] The utility model aims at the above-mentioned problems existing in the prior art, and provides a kind of material feeding roller structure on adhesive tape cutting line. The technical problem to be solved by the utility model is to adapt the cutter wheel to the cutting of the film.
[0004] The purpose of the utility model can be realized by the following technical scheme: a kind of material feeding roller structure on adhesive tape cutting line, characterized by including two end half roller cylinders, one middle roller cylinder and a core shaft, the two end half roller cylinders are fixed at the two ends of the core shaft, the middle roller cylinder is slidably connected to the core shaft along the axial direction of the core shaft, the middle roller cylinder is located between the two end half roller cylinders, the middle part of the middle roller cylinder has a avoiding slot, and a locking bolt is arranged on the middle roller cylinder in the avoiding slot.
[0005] Further, the inner end of the end half roller cylinder has a plurality of interposed insertion strips one, and the two ends of the middle roller cylinder each have an insertion strip two that can be inserted into the gap between adjacent insertion strips one.
[0006] In this scheme, the film supporting and feeding roller at the cutting position is provided with a three-section structure, two end half rollers are rotatably connected to the rack, and the middle roller cylinder in the middle part can move along the core shaft to adjust the position of the avoiding slot to match the position of the cutting cutter wheel. In this way, the cutting cutter wheel can still maintain a large contact line with the film after adjusting the position. BRIEF DESCRIPTION OF DRAWINGS
[0007] Figure 1 is the schematic diagram of the material feeding roller structure.
[0008] In the figure, 1 is an end half roller cylinder; 2 is a middle roller cylinder; 3 is a core shaft; 4 is an avoiding slot; 5 is a locking bolt; 6 is an insertion strip one; and 7 is an insertion strip two. Detailed Implementation
[0009] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.
[0010] like Figure 1 The feed roller structure shown includes two end half rollers 1, an intermediate roller 2, and a mandrel 3. The two end half rollers 1 are fixed to both ends of the mandrel 3. The intermediate roller 2 is slidably connected to the mandrel 3 along the axial direction of the mandrel 3. The intermediate roller 2 is located between the two end half rollers 1. The middle part of the intermediate roller 2 has a relief groove 4. A locking bolt 5 is provided on the intermediate roller 2 in the relief groove 4. The locking bolt 5 can fix the intermediate roller 2 to the mandrel 3.
[0011] The inner end of the end half roller 1 has several alternating inserts 6, and both ends of the middle roller 2 have inserts 7 that can be inserted into the gaps between adjacent inserts 6. The inserts 6 and 7 can form a complete smooth roller surface at the overlapping position, so that the film can be supported at multiple positions.
[0012] In this scheme, the film support feed roller at the cutting position is set as a three-section structure. The two end half rollers are used to rotate and connect with the frame, while the middle roller 2 in the middle can move along the spindle 3 to adjust the position of the clearance groove 4 to match the position of the cutting blade wheel. In this way, the cutting blade wheel can still maintain a large contact line with the film after the position is adjusted.
[0013] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
