Description

Technical Field

[0001] This utility model relates to the field of film dust removal, and in particular to a dust removal structure for coating and printing functional films. Background Technology

[0002] In modern industry, the dust removal structure of coating and printing functional films is crucial. It adopts high-efficiency dust removal components such as silicone rollers, combined with electrostatic elimination and dust collection technology, to ensure the cleanliness of the film surface, improve the quality of subsequent coating and printing, and meet the high precision requirements of films in the electronics, optoelectronics and other fields.

[0003] The core function of existing dust removal structures for coated and printed functional films is to remove dust, impurities, and static electricity from the film surface, preventing problems such as adhesion, scratches, or uneven coating during subsequent processing. It is a key structure to ensure the cleanliness of the film surface and improve the coating or printing quality. Most of them are located at the winding position. The adhesive layer of the dust removal roller captures dust through physical adsorption. However, for films that need to be processed for a long time, the adhesive layer of the dust removal roller will be gradually filled with fine dust, resulting in a decrease in adhesion. The dust removal roller needs to be replaced, and the downtime for replacing the dust removal roller reduces production efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a dust removal structure for coating and printing functional films, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A dust removal structure for coating and printing functional films includes a first support frame and a dust removal roller rotatably connected to the first support frame. A first track body is provided at the bottom of the first support frame, and a track rod is slidably connected inside the first track body. Second support frames are fixedly connected to both ends of the track rod. Cleaning rollers are installed on both sets of second support frames, and the cleaning rollers closer to the dust removal rollers are in contact with the dust removal rollers. A driving assembly is installed on the first support frame. The driving assembly is used to adjust the position of the dust removal rollers. The driving assembly includes:

[0006] A servo motor is mounted at the bottom of the first support frame;

[0007] The threaded rod is fixedly connected to the output end of the servo motor.

[0008] An adjusting block is fixedly connected to the track rod, and the threaded rod is threadedly connected to the adjusting block.

[0009] A first limiting member is fixedly connected to the second support frame, which is used to initially limit the cleaning roller.

[0010] The second support frame is provided with a second track body, and a track block is slidably connected inside the second track body. A mounting plate is hinged to the track block, and a second limiting member is fixedly connected to the mounting plate. The second limiting member further limits the cleaning roller.

[0011] A bolt body is fixedly connected to the second support frame. The bolt body abuts against the mounting plate, and a fixing bolt is threadedly connected between the mounting plate and the bolt body.

[0012] The second support frame, track rod, and first limiting component are integrally molded and manufactured.

[0013] The dust removal roller and the cleaning roller are coated with an adhesive coating to form a micro-adhesive layer.

[0014] The technical effects and advantages of this utility model are as follows:

[0015] This dust removal structure for coating and printing functional films employs cleaning rollers that can operate alternately on both sides of the dust removal roller. The surface of the cleaning roller is more viscous than that of the dust removal roller, enabling it to adsorb dust from the surface of the dust removal roller. When processing films that require a long time, the cleaning roller adsorbs the dust from the surface of the dust removal roller, ensuring the adsorption effect of the dust removal roller surface. At the same time, the drive component can switch the positions of the two cleaning rollers to achieve the purpose of continuous operation during processing. Attached Figure Description

Detailed Implementation

[0020] 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.

[0021] This utility model provides, for example Figure 1 - Figure 3 The dust removal structure shown for coating and printing functional films includes a first support frame 1, which serves as the main support component of the entire dust removal structure, providing mounting positions for the dust removal roller 11, the first track body 12, and the drive assembly 3, ensuring that these components can be stably arranged in the appropriate positions for operation. The dust removal roller 11 is rotatably connected to the first support frame 1. The dust removal roller 11 is a key component that directly contacts the coating and printing functional film and removes dust from the film surface. Its surface is coated with an adhesive layer to form a micro-adhesive layer, which adsorbs fine dust from the film surface through adhesion. A first track body 12 is provided at the bottom of the first support frame 1, and a track rod 22 is slidably connected inside the first track body 12. The track rod 22 connects to the second support frame 2 and guides its movement, while also being fixedly connected to an adjusting block 33. The track rod 22 moves through the cooperation of the adjusting block 33 and the threaded rod 32. Second support frames 2 are fixedly connected to both ends of the track rod 22. Cleaning rollers 21 are installed on both sets of second support frames 2. The cleaning roller 21 closest to the dust removal roller 11 is in contact with the dust removal roller 11. The surface adhesion of the cleaning roller 21 is greater than that of the dust removal roller 11, enabling it to adsorb dust from the surface of the dust removal roller 11 and ensuring the adsorption effect of the dust removal roller 11. The two sets of cleaning rollers 21 can operate alternately to meet the needs of long-term processing without stopping the machine.

[0022] A drive assembly 3 is mounted on the first support frame 1. The drive assembly 3 is used to adjust the position of the dust removal roller 11. The drive assembly 3 includes:

[0023] The servo motor 31 is installed at the bottom of the first support frame 1 and serves as the power source for the drive assembly 3, providing power for the rotation of the threaded rod 32.

[0024] The threaded rod 32 is fixedly connected to the output end of the servo motor 31. It rotates under the drive of the servo motor 31. Through the threaded connection with the adjusting block 33, the rotational motion is converted into linear motion, thereby driving the adjusting block 33 and the track rod 22 to move.

[0025] Adjusting block 33 is fixedly connected to track rod 22. Threaded rod 32 is threadedly connected to adjusting block 33. When threaded rod 32 rotates, adjusting block 33 moves along threaded rod 32, thereby driving track rod 22 to move.

[0026] The second support frame 2 is fixedly connected to the first limiting member 23, which is used to initially limit the cleaning roller 21 to prevent the cleaning roller 21 from undergoing large positional displacement during installation or operation.

[0027] The second support frame 2 is provided with a second track body 24, which provides a sliding track for the track block 42, allowing the track block 42 to slide inside it, thereby driving the mounting plate 4 and the second limiting member 41 to move, and realizing further limiting adjustment of the cleaning roller 21. The track block 42 is slidably connected inside the second track body 24. The track block 42 drives the mounting plate 4 to move through sliding, so as to adjust the position of the second limiting member 41. The mounting plate 4 is hinged on the track block 42, and the second limiting member 41 is fixedly connected on the mounting plate 4. The second limiting member 41 further limits the cleaning roller 21.

[0028] A locking bolt body 25 is fixedly connected to the second support frame 2. The locking bolt body 25 is used to fix the position of the mounting plate 4 and prevent the mounting plate 4 from shaking when it does not need to be moved, so as to ensure the limiting effect of the second limiting member 41 on the cleaning roller 21. The locking bolt body 25 abuts against the mounting plate 4. A fixing bolt 5 is threadedly connected between the mounting plate 4 and the locking bolt body 25 to enhance the stability of the mounting plate 4 and ensure that the second limiting member 41 can stably limit the cleaning roller 21.

[0029] The second support frame 2, the track rod 22, and the first limiting component 23 are manufactured as a single piece. The single-piece structure is stable and has a long service life.

[0030] The surfaces of the dust removal roller 11 and the cleaning roller 21 are coated with an adhesive coating to form a micro-adhesive layer, which facilitates the adsorption of dust by the dust removal roller 11 and the cleaning roller 21.

[0031] Example 1: In the actual production process of coating and printing functional films, the dust removal structure is installed at a suitable position on the film production line. The first support frame 1 is fixed on the production line frame to ensure its stability. Then, the dust removal roller 11 is installed on the first support frame 1, allowing it to rotate normally and contact the film surface. Next, the track rod 22 is installed inside the first track body 12, and the cleaning roller 21 is installed on the second support frame 2, so that the cleaning roller 21 closest to the dust removal roller 11 is in contact with the dust removal roller 11. Film production can then begin. The dust removal roller 11 adsorbs fine dust from the film surface through its micro-adhesive layer. The adhesiveness of the cleaning roller 21 surface is greater than that of the dust removal roller 11. The adhesiveness of the surface of the cleaning roller 11 allows it to attract dust. After a period of time, the servo motor 31 is activated, driving the threaded rod 32 to rotate. The threaded rod 32 is threadedly connected to the adjusting block 33, causing the adjusting block 33 to move the track rod 22. The track rod 22 then moves the second support frame 2, moving the cleaning roller 21, which was not initially in contact with the dust-collecting roller 11, to a position where it is in contact with it. The cleaning roller 21 that was previously attracted to dust is then removed. The new cleaning roller 21, with a surface adhesiveness greater than that of the dust-collecting roller 11, can continue to attract dust from its surface, ensuring the effective adsorption of the dust-collecting roller 11. In this way, the two sets of cleaning rollers 21 can work alternately, eliminating the need to stop the machine to replace the dust-collecting rollers 11 during processing, thus greatly improving production efficiency.

[0032] Example 2: Replace the cleaning roller 21 that has absorbed dust. After replacement, it can be cleaned. First, support the bottom of the cleaning roller 21 with a tool. Then, unscrew the fixing bolt 5 that connects the mounting plate 4 and the locking bolt body 25. Then, pull the track block 42 to slide within the second track body 24. Then, release the second limiting member 41 from limiting the cleaning roller 21. After bending the mounting plate 4 at ninety degrees, the cleaning roller 21 can be removed. The installation process is the reverse of the above steps.

[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
