Description

Technical Field

[0001] This utility model belongs to the field of polarizer processing technology, specifically relating to a large polarizer receiving and cleaning fixture. Background Technology

[0002] In the production process of large polarizer materials, the surface cleanliness directly affects the display quality and performance of the final product. After the large polarizer is processed, it usually needs to be transported and collected by a receiving conveyor belt. However, in the actual production process, there may be contaminants such as dust, particles, and fibers on the surface of the receiving conveyor belt. These contaminants are very easy to adhere to the surface of the polarizer during the transport process, causing the polarizer to be contaminated and thus affecting its subsequent processing quality.

[0003] Currently, the existing technologies mainly adopt the following methods to address the cleaning problem of receiving conveyor belts:

[0004] 1. Manual cleaning: Regularly arrange personnel to wipe or rinse the surface of the conveyor belt. Although this method can remove some contaminants, it is inefficient and it is difficult to ensure the thoroughness and consistency of cleaning. At the same time, it increases labor costs and safety risks.

[0005] 2. Fixed cleaning device: A fixed cleaning brush or scraper is set up next to the belt to remove contaminants from the surface of the belt by physical means. However, this device can often only clean large particles of contaminants on the surface of the belt. It is not effective at cleaning fine dust and fibers, and it is prone to wear after long-term use and needs to be replaced frequently.

[0006] Therefore, this utility model proposes a large polarizer collection and cleaning fixture. Utility Model Content

[0007] The purpose of this utility model is to provide a large polarizer receiving and cleaning fixture to solve the problems mentioned in the background art, such as the low efficiency of manual cleaning of existing receiving conveyor belts, the difficulty in ensuring thorough and consistent cleaning, and the poor cleaning effect of using fixed cleaning brushes or scrapers.

[0024] 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.

[0025] Example 1

[0026] Please see Figures 1 to 4 This is the first embodiment of the present utility model, which provides a technical solution: a large polarizer collecting and cleaning fixture, comprising...

[0027] Two support beams 1 are symmetrically fixed to the top of the conveyor beam 7; a cylinder 2 is fixed to the front surface of the support beam 1; a movable seat plate 3 is slidably mounted on the front surface of the support beam 1 and connected to the piston rod at the free end of the cylinder 2; a shaft seat plate 4 is welded and fixed to the front surface of the support beam 1 and located below the movable seat plate 3; a rubber wheel 6 is rotatably mounted between the two shaft seat plates 4 and rolls in contact with the take-up belt 8 via a rotating shaft; and a dust-adhesive wheel 5 is rotatably mounted between the two movable seat plates 3 and rolls in contact with the rubber wheel 6. The surface of the dust-adhesive wheel 5 is covered with multiple layers of sticky dust-adhesive paper, which can be peeled off and replaced periodically. When replacing, simply peel off the outermost layer to expose the inner layer for continued use. During actual operation, when the take-up belt 8 starts running, the cylinder 2 is activated, causing the movable seat plate 3 to... As the adhesive roller 5 moves downward, it rolls and adheres to the rubber roller 6. This causes the take-up belt 8 to rotate along with the rubber roller 6 and the adhesive roller 5 during operation. During this process, the rubber roller 6 first adsorbs small dust, particles, and fibers from the surface of the take-up belt 8, and these contaminants are then picked up by the adhesive roller 5 as it rotates. This results in these small dust, particles, and fibers being stuck to the surface of the adhesive roller 5. Through the cooperation of the adhesive roller 5 and the rubber roller 6, the surface of the take-up belt 8 can be effectively and continuously cleaned during its operation. Later, without stopping the take-up belt 8, the cylinder 2 can be activated to raise the movable seat plate 3 and the adhesive roller 5, and the adhesive paper on the surface of the adhesive roller 5 can be replaced periodically.

[0028] In this embodiment, preferably, a support plate 11 is welded and fixed to the front surface of the support beam 1, and the cylinder 2 is installed on the top surface of the support plate 11 to achieve stable installation of the cylinder 2. The piston rod at the free end of the cylinder 2 passes through to the bottom of the support plate 11 and is connected to the movable seat plate 3, so that the cylinder 2 can drive the movable seat plate 3 to rise and fall when it runs.

[0029] In this embodiment, preferably, both ends of the dust-sticking wheel 5 are provided with a central shaft 51, and the ends of the central shaft 51 are fixed with a shaft 52. The surface of the movable seat plate 3 is provided with a U-shaped notch 34 for the shaft 52 to be inserted. The shaft 52 is inserted and rotated in the U-shaped notch 34, so that the central shaft 51 and the dust-sticking wheel 5 can rotate smoothly between the two movable seat plates 3.

[0030] In this embodiment, preferably, a fixing plate 31 is installed on the front surface of the movable seat plate 3, and a limiting block 33 is welded and fixed on the back of the fixing plate 31, with the limiting block 33 embedded in the U-shaped notch 34.

[0031] In this embodiment, preferably, a fixing structure 32 is provided between the fixed plate 31 and the movable seat plate 3.

[0032] In this embodiment, preferably, the fixing structure 32 includes two fastening bolts 321 disposed at both ends of the fixing plate 31 and a threaded groove 322 on the surface of the movable seat plate 3 that matches the fastening bolts 321. The threaded end of the fastening bolt 321 passes through the fixing plate 31 and is screwed into the threaded groove 322, so that the fixing plate 31 can be stably fixed on the surface of the movable seat plate 3. The fixing structure 32 also includes two positioning blocks 323 welded and fixed to the back of the fixing plate 31, and the surface of the movable seat plate 3 has two positioning slots 324 corresponding to the positioning blocks 323. The positioning blocks 323 are inserted into the positioning slots 324 so that when the fixing plate 31 is installed, the positioning blocks 323 can be inserted into the positioning slots 324 to complete the initial positioning, and then the fixing plate 31 can be fixed by the fastening bolts 321.

[0033] Example 2

[0034] Please see Figures 1 to 5 This is the second embodiment of the present invention. This embodiment is based on the previous embodiment, but the difference is that an auxiliary rolling structure is designed on the inner wall of the U-shaped notch 34 and the inner wall of the limiting pressure block 33. This structure can support the shaft 52, ensure the effective rotation of the shaft 52, and avoid the problem of the shaft 52 directly rubbing against the inner wall of the U-shaped notch 34 and the inner wall of the limiting pressure block 33, which would cause poor operation.

[0035] In this embodiment, preferably, the inner wall of the U-shaped notch 34 and the inner wall of the limiting pressure block 33 are both provided with an auxiliary rolling structure. The auxiliary rolling structure includes a roller groove 351 and an auxiliary support roller 352. The inner wall of the U-shaped notch 34 and the inner wall of the limiting pressure block 33 are both provided with roller grooves 351, and the auxiliary support roller 352 is rotatably installed in the roller groove 351. The auxiliary support roller 352 can effectively support the shaft 52 by rolling contact with the shaft 52, while ensuring the normal operation of the shaft 52.

[0036] Although embodiments of the present invention have been shown and described (see the detailed description above), 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.
