Description

Technical Field

[0001] This utility model relates to the field of pressure roller cleaning technology, and more specifically, to a roller wall scraping device. Background Technology

[0002] like Figure 1 As shown, in the existing production process, the film passes through a glue roller to coat one side of the film with glue, forming an adhesive surface. The adhesive surface and the paper are then pressed together by a composite roller. When the film and paper are pressed together, glue overflows from the edges of the film due to pressure. Since the width of the paper is greater than the width of the film, the overflowing glue between the film and paper adheres to the outer wall of the lower pressure roller. If the glue on the lower pressure roller is not cleaned in time, subsequent films will be affected by the glue, resulting in problems such as bubbles and white spots. It is necessary to arrange personnel to clean the glue on the roller wall, which is very labor-intensive. Therefore, a technical solution is needed to solve the above problems. Utility Model Content

[0022] The technical solutions in this embodiment will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0023] like Figures 2-5 As shown, this embodiment discloses a roller wall scraping device, including at least two scraper assemblies 2 and two first moving assemblies 3. The scraper assemblies 2 are located on one side of the roller 1. Each first moving assembly 3 is connected to one scraper assembly 2. The first moving assembly 3 includes a first slide rail 31 and a first slider 32. The first slide rail 31 extends axially toward the roller 1, and the first slider 32 can slide along the first slide rail 31. The first slider 32 is slidably mounted on the first slide rail 31 and can adjust the axial position of the scraper assembly 2. The width of the film pressed by the roller 1 is adjusted. The scraper assembly 2 is installed on the first slider 32. Each scraper assembly 2 includes at least one blade 21. The blade 21 corresponds to the edge of the composite film. The glue squeezed out from the edge of the film can be scraped off by the blade 21. The blade 21 contacts the outer wall of the roller 1. The blade 21 faces the opposite direction of the rotation of the roller 1. As the roller 1 rotates, the blade 21 remains stationary. The glue on the outer wall of the roller 1 is scraped off by the blade 21 located on the rotation path of the outer wall of the roller 1, realizing the function of automatic glue scraping.

[0024] More preferably, the first slider 32 is fitted with a locking button 321, which is threadedly connected to the first slider 32. The locking button 321 can lock and fix the first slider 32 to the first slide rail 31, thereby fixing the position of the first slider 32 on the first slide rail 31.

[0025] The scraper assembly 2 includes a base plate 22, a guide seat 23, an adjustment component 25, and a blade holder 26. The base plate 22 is fixedly connected to the first slider 32. The guide seat 23 is installed on the base plate 22. The adjustment component 25 is installed on the guide seat 23 and is slidably connected to the guide seat 23. A rack 24 is installed on the upper end face of the guide seat 23. The adjustment component 25 includes a housing 251, a drive rod 252, and a locking rod 253. The guide seat 23 is provided with a guide bar 231. The housing 251 is slidably connected to the guide bar 231. The cross-section of the guide bar 231 is trapezoidal. The width of the guide bar 231 gradually decreases towards the base plate 22. The housing 251 is provided with a guide groove 2511 corresponding to the guide bar 231. A vertical limit is formed between the housing 251 and the guide bar 231, allowing the housing 251 to slide along the length of the guide bar 231.

[0026] The drive rod 252 is rotatably mounted on the housing 251 via a bearing. The drive rod 252 includes a tooth 2521, which meshes with the rack 24. When the drive rod 252 is rotated, the tooth 2521 can drive the housing 251 to slide along the guide bar 231, thereby adjusting the distance between the blade 21 and the roller 1, so that the blade 21 can abut against or move away from the roller 1.

[0027] The housing 251 is provided with a side plate 2512, which is located on the outer side wall of the housing 251. The locking rod 253 passes through the side plate 2512 and is threadedly connected to the side plate 2512. The locking rod 253 is a bolt. By turning the locking rod 253, the housing 251 is locked. The lower end of the locking rod 253 can abut against the bottom plate 22, so that the drive rod 252 cannot rotate to drive the housing 251 to move, thus playing a role in fixing the blade 21 after positioning.

[0028] The blade holder 26 is installed on the upper end of the adjusting assembly 25. The adjusting assembly 25 can control the blade 21 to move closer to or further away from the roller 1. The blade holder 26 includes a mounting plate 261 and a clamping plate 262. The mounting plate 261 is fixedly installed on the adjusting assembly 25. The mounting plate 261 has a vertical plate 2611. The clamping plate 262 is fixedly installed on the vertical plate 2611 and is fixed to the vertical plate 2611 by bolts. The blade 21 is installed on the blade holder 26 and clamped between the vertical plate 2611 and the clamping plate 262. The blade 21 is above the clamping bolt. Tightening the bolt can fix the blade 21. The blade 21 extends at least partially out of the upper end of the clamping plate 262 and the vertical plate 2611. The blade edge of the blade 21 faces upward. The adjusting assembly 25 can be used to adjust the vertically set blade 21 to move closer to the roller 1.

[0029] This embodiment also includes a second moving component 4, which includes a second slide rail 41 and a second slider 42. The second slide rail 41 extends axially toward the roller 1. The second slide rail 41 drives the second slider 42 to slide along the second slide rail 41. The second slide rail 41 is driven by a motor to enable the second slider 42 to slide back and forth along the second slide rail 41. A scraper assembly 2 is installed on the second slider 42. When the blade 21 of the scraper assembly 2 located in the second moving component 4 contacts the outer wall of the roller 1, it can clean the outer wall of the roller 1 while reciprocating, so as to prevent residual particles or dust on the outer wall of the roller 1 from affecting the quality of the film pressing.
