Description

Technical Field

[0001] This utility model relates to the field of coating equipment technology, specifically a coating device for single-sided adhesive processing. Background Technology

[0002] Single-sided adhesive tape is a common type of adhesive product, characterized by an adhesive layer applied only to one side of the material, while the other side is non-adhesive (usually covered with a release film or protective layer). It is widely used in packaging, office supplies, electronics, printing, automobiles, and many other fields, becoming an important material in daily life and industrial production due to its convenient adhesive properties. Plastic films, such as PET (polyester), BOPP (polypropylene), and PVC (polyvinyl chloride), are water-resistant and tensile-resistant, suitable for packaging tapes. Paper, such as kraft paper and coated paper, is often used for labels and envelope sealing adhesives. Fabrics / fibers, such as cloth-based and non-woven fabrics, are used for industrial tapes or special applications (such as waterproofing and abrasion resistance). Metal foils, such as aluminum foil, have high-temperature resistance and conductivity, and are used in the electronics or automotive fields.

[0003] In the modern industrial processing of single-sided adhesive, the lamination process is a key link in ensuring product quality. The performance of the equipment directly affects the quality of the final product and production efficiency. Traditional lamination equipment generally adopts rigid pressing technology. This technology uses a mechanical structure to drive rigid pressure rollers or plates to bond the protective film to the single-sided adhesive substrate with constant pressure. However, this technology has obvious limitations: when the pressure parameters of the pressing components are set too high or the pressure becomes uncontrolled due to equipment aging or mechanical errors, the high-intensity rigid pressure will directly act on the surface of the single-sided adhesive and the lamination material. For ultra-thin single-sided adhesive films with a thickness of only tens of micrometers and soft release films, excessive pressure can easily cause wrinkles and damage to the film surface, and even damage the internal structure of the single-sided adhesive substrate, resulting in problems such as local delamination and adhesive overflow. These defects not only reduce the appearance quality of the single-sided adhesive products, but also directly affect their adhesion performance and use effect, thus leading to a significant decline in the yield of single-sided adhesive processing. Utility Model Content

[0004] The purpose of this invention is to provide a laminating device for single-sided adhesive processing, which solves the problem of the rigid pressing technology commonly used in laminating devices. This technology uses a mechanical structure to drive a rigid pressure roller or plate to bond the protective film to the single-sided adhesive substrate with constant pressure. However, this technology has obvious limitations: when the pressure parameters of the pressing component are set too high or the pressure becomes uncontrolled due to equipment aging or mechanical errors, the high-intensity rigid pressure will directly act on the surface of the single-sided adhesive and the laminating material. For ultra-thin single-sided adhesive films with a thickness of only tens of micrometers and soft release films, excessive pressure can easily cause wrinkles and damage to the film surface, and even damage to the internal structure of the single-sided adhesive substrate, resulting in problems such as local delamination and adhesive overflow. These defects not only reduce the appearance quality of the single-sided adhesive product, but also directly affect its adhesion performance and use effect, thus leading to a significant decline in the yield of single-sided adhesive processing.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-4 A laminating device for single-sided adhesive processing includes a base plate 1, a worktable 2 fixedly connected to the top of the base plate 1, a support roller 3 fixedly connected to the top of the worktable 2, a laminating roller 4 disposed on the top of the support roller 3, a spacing adjustment frame 5 sleeved on the surface of the laminating roller 4, the bottom of the spacing adjustment frame 5 extending to the bottom of the worktable 2, an electric cylinder 6 fixedly connected to the bottom of the inner wall of the spacing adjustment frame 5, the top of the electric cylinder 6 fixedly connected to the bottom of the worktable 2, and an elastic anti-pressure damage mechanism 7 sleeved on the surface of the laminating roller 4.

[0021] Please see Figure 1-4Limiting blocks 8 are fixedly connected to both the front and rear sides of the workbench 2, and the limiting blocks 8 are located inside the spacing adjustment frame 5.

[0022] Furthermore, by setting the limit block 8, the spacing adjustment frame 5 can be stabilized, preventing it from loosening during the sliding process and improving the lifting efficiency of the spacing adjustment frame 5.

[0023] Please see Figure 1-4 A limiting plate 9 is fixedly connected to the surface of the limiting block 8, and the inner wall of the limiting plate 9 is in contact with the surface of the spacing adjustment frame 5.

[0024] Furthermore, by setting the limiting plate 9, the spacing adjustment frame 5 can be wrapped and limited to prevent it from tilting during use, thus improving the performance of the spacing adjustment frame 5.

[0025] Please see Figure 1-4 Vertical rods 10 are provided on both the front and rear sides of the spacing adjustment frame 5. The bottom of the vertical rods 10 is fixedly connected to the top of the base plate 1, and the top of the vertical rods 10 is fixedly connected to the bottom of the workbench 2.

[0026] Furthermore, the vertical rod 10 can be used to position the bottom of the spacing adjustment frame 5, thereby improving the sliding trajectory maintenance effect of the spacing adjustment frame 5 and preventing the spacing adjustment frame 5 from sliding incorrectly.

[0027] The specific implementation process of this utility model is as follows: When in use, the single-sided adhesive and the film are introduced between the support roller 3 and the film coating roller 4. The electric cylinder 6 is started, and the electric cylinder 6 drives the spacing adjustment frame 5 to move downward. The spacing adjustment frame 5 drives the film coating roller 4 to move downward. When the spacing between the film coating roller 4 and the support roller 3 reaches a suitable level, the single-sided adhesive and the film coating can be pressed and bonded together.

[0028] When the electric cylinder 6 is misoperated, and the electric cylinder 6 drives the laminating roller 4 to press down with excessive force, although the electric cylinder 6 continues to drive the spacing adjustment frame 5 to move downward, the slider 71 inside the spacing adjustment frame 5 and the laminating roller 4 stop descending. The spacing adjustment frame 5 compresses the spring 72, and the spring 72 will relieve the excess pressure of the spacing adjustment frame 5 to prevent the single-sided adhesive from being damaged.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
