Description

Technical Field

[0001] This utility model relates to the field of traction rollers, and in particular to an anti-sticking auxiliary traction roller for tape edge material, a tape edge material conveying mechanism, and a tape edge material processing system. Background Technology

[0002] In the tape manufacturing process, the tape is traction and slitting before being fed out by rollers. This process generates a large amount of waste material, which, if not handled, leads to waste and accumulation in certain processes. Currently, the waste material is output to the recycling device via conveyor rollers. The waste material retains residual heat after processing, and to prevent it from sticking to the conveyor rollers when heated, the conveyor rollers are usually coated with an anti-stick coating, such as a Teflon coating, on the contact area with the waste material. However, Teflon coatings have poor wear resistance and need to be reapplied periodically. Especially when the waste material damages the Teflon coating on the conveyor rollers during processing, jamming occurs, requiring long downtime for maintenance and the waste material to be cut off with a knife. However, cutting with a knife reduces the lifespan of the conveyor rollers. Utility Model Content

Furthermore, features defined with "first" and "second" may explicitly or implicitly include one or more of these features, used to distinguish descriptive features, without any order or emphasis. In the description of this utility model, unless otherwise stated, "multiple" means two or more.

[0031] like Figure 1-5 A non-stick auxiliary traction roller for tape edge material, comprising a roller surface 101 and a connecting portion 102; the connecting portion 102 is installed at the left and right ends of the roller surface 101;

[0032] The roller surface 101 is provided with an anti-stick three-dimensional layer 1011 along its outer side; the anti-stick three-dimensional layer 1011 is provided with a plurality of anti-stick bumps 1012 distributed longitudinally and laterally, the anti-stick bumps 1012 are square in shape, and corners 1013 are formed between two adjacent surfaces of the anti-stick bumps 1012; a bump gap 1014 is formed between two adjacent anti-stick bumps 1012.

[0033] The width 'a' of the anti-stick bump 1012 circumferentially toward the roller surface 101 is 1.5 to 2.5 mm; the size of the bump gap 1014 is 1.5 to 2.5 mm.

[0034] This solution provides an anti-sticking auxiliary traction roller for tape edge material, which has an anti-sticking three-dimensional layer 1011 on the roller surface 101. The anti-sticking protrusions 1012 in the anti-sticking three-dimensional layer 1011 are square-shaped. The combination of the size of the anti-sticking protrusions 1012 and the protrusion gap 1014 can maintain the long-term anti-sticking stability of the anti-sticking auxiliary traction roller, and solves the problem of low wear resistance of existing anti-sticking coating layers, which reduces the anti-sticking stability.

[0035] Generally, the anti-stick auxiliary traction roller has a roller surface 101 and a connecting part 102. The roller surface 101 is the area that mainly contacts the edge material; the connecting part 102 is installed at both ends of the roller surface 101 and mainly serves a fixing function. The roller surface 101 has an anti-stick three-dimensional layer 1011 on its outer surface; the anti-stick three-dimensional layer 1011 is specifically a number of anti-stick protrusions 1012 distributed longitudinally and laterally; the anti-stick protrusions 1012 are square-shaped, such as a cuboid structure or a cube structure, that is, there are corners 1013 between two adjacent faces; when the anti-stick auxiliary traction roller rotates, the anti-stick protrusions 1012 replace the circumferential surface of the roller surface 101 to contact the edge material; on the one hand, based on the protrusion gaps 1014 between the anti-stick protrusions 1012, the protrusion gaps 1014 reduce the actual contact area between the anti-stick three-dimensional layer 1011 and the edge material, the actual contact area between the edge material and the anti-stick protrusions 1012 is reduced. The contact area is smaller, resulting in lower adhesion. Furthermore, the width of the bump gap 1014 is similar to that of the anti-stick bump 1012, ranging from 1.5 to 2.5 mm. The bump gap 1014 is the non-adhesive area of ​​the edge material, while the anti-stick bump 1012 is the adhesive area. Since the edge material lacks continuous adhesive points, it is easier to separate from the outer surface of the roller face 101. Simultaneously, the corners 1013 of the anti-stick bump 1012 are sharper and have higher mechanical strength. When a corner 1013 of an anti-stick bump 1012 rotates to contact the edge material, the contact area between the anti-stick bump 1012 and the edge material is minimized, making it easier for the corner 1013 to separate from the edge material. Moreover, the sharp corner 1013's high mechanical strength makes it difficult for the edge material to damage the anti-stick bump 1012. Therefore, the long-term anti-stick stability of the anti-stick auxiliary traction roller can be maintained, solving the problem of low wear resistance and reduced anti-stick stability in existing anti-stick coating layers.

[0036] The height b of the anti-stick bump 1012 can be optimized to be 1 to 1.5 mm.

[0037] Within this height range, the distance between the top and bottom surfaces of the anti-sticking bump 1012 is optimal, effectively separating the edge material. Simultaneously, the height of the anti-sticking bump 1012 should not be excessive; otherwise, it will protrude too much from the outer surface of the roller face 101, easily puncturing the edge material and ensuring the stability of edge material conveying.

[0038] Optimally, it also includes an anti-stick coating 103;

[0039] The anti-stick three-dimensional layer 1011 is disposed in the middle of the roller surface 101, and the anti-stick coating 103 is disposed on the outer side of the roller surface 101 and located at the left and right ends of the anti-stick three-dimensional layer 1011.

[0040] The anti-stick coating 103 has an anti-stick effect and is mainly made of anti-stick paint. It is set at both ends of the anti-stick layer 1011. The anti-stick auxiliary traction roller mainly uses the anti-stick layer 1011 to convey edge material, and the anti-stick coating 103 is generally not used for edge material conveying. The anti-stick coating 103 can improve the cleanliness of the anti-stick auxiliary traction roller and prevent impurities in the factory from adhering to the roller surface 101, causing impurities to accumulate towards the anti-stick layer 1011. At the same time, the anti-stick coating 103 can also prevent chemical residues such as lubricating oil from the connecting part 102 from remaining in the anti-stick coating 103, and prevent chemical residues from adhering when the edge material exceeds the anti-stick layer 1011, thereby improving the cleanliness of the roller surface 101.

[0041] Optimally, the roller surface 101 is provided with a plurality of sequentially arranged circular layers 104 outside both ends of the anti-stick three-dimensional layer 1011, and the outer diameter of each circular layer 104 is reduced in the direction away from the anti-stick three-dimensional layer 1011; the anti-stick coating 103 is disposed on the circular layer 104.

[0042] In this design, the roller surface 101 has a circular layer 104 in the area outside the anti-stick layer 1011. The circular layer 104 is a typical roller surface with a columnar structure, mainly used for attaching the anti-stick coating 103. The anti-stick coating 103 in this design has a stepped structure, meaning the outer diameter of the circular layer 104 decreases towards the direction away from the anti-stick layer 1011. The outer diameter of the circular layer 104 is larger closer to the anti-stick layer 1011 and smaller closer to the connecting part 102. Thus, the outer diameter of the anti-stick coating 103 is different for each circular layer 104, and the anti-stick coatings 103 of adjacent circular layers 104 are independently separated. Damage to one anti-stick coating 103 will not cause damage to another anti-stick coating 103, reducing the replacement cost of the anti-stick coating 103.

[0043] Ideally, the difference in outer diameter between two adjacent circular layers 104 is 2–4 mm.

[0044] When the difference between the circular layers 104 is 2-4mm, the outer diameter difference can accommodate the cutting edge of the tool, so that the cutting edge of the tool can be vertically or horizontally cut into the circular layer 104, and the edge material that exceeds the circular layer 104 can be trimmed; especially when the two anti-stick auxiliary traction rollers are close together, a gap of 4-8mm is formed at the outer diameter difference position, which satisfies the trimming of the edge material during the conveying process.

[0045] Optimally, the length ratio of the anti-stick three-dimensional layer 1011 to the length of the roller surface 101 is (0.3~0.5):1.

[0046] The anti-stick layer 1011 occupies 1 / 2 or less of the length of the roll face 101. The proportion of the anti-stick layer 1011 does not need to be too long, as too long will increase processing costs, and too low will reduce the anti-stick properties of the edge material.

[0047] A tape edge material conveying mechanism is provided with a lifting driver 02 and an anti-sticking auxiliary traction roller 01 for tape edge material according to any of the above embodiments;

[0048] The anti-sticking auxiliary traction rollers are arranged in pairs; the output end of the lifting driver is connected to one of the anti-sticking auxiliary traction rollers, and is used to drive the anti-sticking auxiliary traction rollers to move up and down, so that the two anti-sticking auxiliary traction rollers move towards each other or away from each other.

[0049] The anti-sticking auxiliary traction roller in this solution is used in the processing device for tape edge material. It is mainly used to receive and convey tape edge material. The anti-sticking auxiliary traction roller and the tape edge material are clamped together and driven to convey the tape edge material under the action of rotation. The tape edge material is difficult to stick to the anti-sticking auxiliary traction roller for a long time, and it can prevent the edge material from wearing the anti-sticking auxiliary traction roller for a long time.
