Description

Technical Field

[0001] This utility model relates to the field of coating roller technology, specifically a coating roller for a high-speed tape coating machine. Background Technology

[0002] In modern industrial production, adhesive tape serves as an important packaging, fixing, and protective material. Its quality and production efficiency directly impact the manufacturing quality and cost-effectiveness of downstream industries. As the core equipment of an adhesive tape production line, the design and performance of the coating rollers in a high-speed adhesive tape coating machine directly determine the coating uniformity, thickness accuracy, and production efficiency. To prevent adhesive from sticking to the outer surface of the coating roller, a non-stick sleeve made of anti-stick material is wrapped around its outer surface. However, the surface of the non-stick sleeve is easily damaged and needs frequent replacement to ensure the coating roller's effectiveness.

[0003] Currently, the anti-stick sleeves on the surface of coating rollers are usually fixed to the roller body with fasteners to prevent the anti-stick sleeves from rotating and sliding on the roller body during use. Although this method of installation is stable, it is relatively inconvenient to disassemble and install during later maintenance. Utility Model Content

[0004] The purpose of this invention is to provide a coating roller for a high-speed tape coating machine to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a coating roller for a high-speed tape coating machine, comprising a roller body, a threaded groove at one end of the roller body, a first limiting ring movably connected to one end of the roller body, a threaded ring fixedly connected to one side of the first limiting ring, the threaded ring being threadedly connected to the threaded groove, a second limiting ring fixedly connected to the other end of the roller body, two first positioning grooves symmetrically opened on one side of the second limiting ring, two second positioning grooves symmetrically opened on the outer circumference of the middle part of the roller body, a sleeve slidably connected to the middle part of the roller body, two positioning strips symmetrically fixedly connected to the inner wall of the sleeve, the positioning strips being engaged in the corresponding second positioning grooves, an anti-stick sleeve fixedly connected to the outer circumference of the sleeve, the two ends of the sleeve respectively abutting against the first limiting ring and the second limiting ring, two positioning plates symmetrically fixedly connected to one end of the sleeve, the two positioning plates being engaged in the corresponding first positioning grooves.

[0006] Preferably, two grooves are provided on the other side of the first limiting ring, and the two grooves are symmetrically arranged about one end of the roller body.

[0007] Preferably, the two ends of the anti-stick sleeve abut against the first limiting ring and the second limiting ring respectively, and the outer diameter of the anti-stick sleeve is smaller than the outer diameter of the first limiting ring and the second limiting ring.

[0008] Preferably, both ends of the second positioning groove are through, and the size of the positioning strip matches the size of the corresponding second positioning groove.

[0009] Preferably, the threaded ring, the roller body, and the first limiting ring are located on the same center line.

[0010] Compared with the prior art, the beneficial effects of this utility model are: the sleeve for installing the anti-stick sleeve is clamped on the roller body by the first limiting ring and the second limiting ring, and its position on the roller body is fixed by the positioning plate and the positioning strip. The second limiting ring is threadedly connected to the roller body by the threaded ring. During later maintenance and disassembly, it is only necessary to rotate the first limiting ring to pull the first limiting ring and the sleeve off the roller body, or install them on the roller body, which is more convenient.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0017] Please see Figure 1-4This utility model provides a technical solution: a coating roller for a high-speed tape coating machine, comprising a roller body 1, a threaded groove 2 at one end of the roller body 1, a first limiting ring 3 movably connected to one end of the roller body 1, a threaded ring 4 fixedly connected to one side of the first limiting ring 3, the threaded ring 4, the roller body 1, and the first limiting ring 3 being located on the same center line, the threaded ring 4 being threadedly connected in the threaded groove 2, and a second limiting ring 6 fixedly connected to the other end of the roller body 1, two first positioning grooves 7 symmetrically opened on one side of the second limiting ring 6. Two second positioning grooves 8 are symmetrically opened on the outer circumference of the middle part of the roller body 1. A sliding sleeve 9 is fitted on the middle part of the roller body 1. Two positioning strips 11 are symmetrically fixedly connected on the inner wall of the sleeve 9. The positioning strips 11 are all engaged in the corresponding second positioning grooves 8. An anti-stick sleeve 12 is fixedly connected on the outer circumference of the sleeve 9. The two ends of the sleeve 9 abut against the first limiting ring 3 and the second limiting ring 6 respectively. Two positioning plates 10 are symmetrically fixedly connected to one end of the sleeve 9. The two positioning plates 10 are all engaged in the corresponding first positioning grooves 7.

[0018] Both ends of the second positioning groove 8 are through. The size of the positioning strip 11 matches the size of the corresponding second positioning groove 8, which facilitates the sliding of the positioning strip 11 in the second positioning groove 8 when the sleeve 9 is disassembled and assembled. Two pull grooves 5 are opened on the other side of the first limiting ring 3. The two pull grooves 5 are symmetrically arranged about one end of the roller body 1, which makes it easy to grasp the first limiting ring 3 during maintenance. The two ends of the anti-stick sleeve 12 abut against the first limiting ring 3 and the second limiting ring 6 respectively. The outer diameter of the anti-stick sleeve 12 is smaller than the outer diameter of the first limiting ring 3 and the second limiting ring 6 to prevent the glue on the anti-stick sleeve 12 from overflowing.

[0019] Specifically, when replacing the anti-stick sleeve 12, insert your finger into the pull groove 5 and rotate the first limiting ring 3 to remove the threaded ring 4 from the threaded groove 2. Remove the first limiting ring 3 from the roller body 1, and then remove the sleeve 9 along with the anti-stick sleeve 12 from the roller body 1. When installing the new anti-stick sleeve 12, put the sleeve 9 on the roller body 1 and insert the positioning strip 11 into the second positioning groove 8. Align the positioning plate 10 with the first positioning groove 7, and push the sleeve 9 to slide on the roller body 1 until the positioning plate 10 is inserted into the groove. In the corresponding first positioning groove 7, the first limiting ring 3 is sleeved on the roller body 1, the first limiting ring 3 is pushed and rotated, the threaded ring 4 is threaded into the threaded groove 2, the first limiting ring 3 is pressed against the sleeve 9, and the position of the anti-stick sleeve 12 is fixed. When this utility model is installed on the high-speed tape coating machine, during operation, the positioning plate 10 and the positioning strip 11 will pull the sleeve 9, while the first limiting ring 3 and the second limiting ring 6 will clamp the sleeve 9, so that the sleeve 9 and the anti-stick sleeve 12 cannot rotate or slide on the roller body 1.

[0020] 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.
