Description

Technical Field

[0001] The utility model relates to the technical field of coating processing devices, in particular to a coating processing device for matte films. Background Art

[0002] Matt film, also known as extinction film, is a packaging film with low gloss, high haze and diffuse reflective extinction effect. It has the advantages of comfortable hand feel, quiet and elegant appearance, and realistic color reproduction when printed. It is widely used in various high-end packaging. In the production of matt film, in order for the matt film to achieve the effect of reflective extinction, the corresponding coating will be applied on the film using a coating machine.

[0003] For example, the public document with application number 202220922858.3 discloses a diffusion film coating processing device. When the first roller of the utility model contacts the diffusion film, it can squeeze the diffusion film, deform the resin adhesive, and push the diffusion agent beads to deviate to form a uniform convex portion, so that the diffusion agent beads are evenly distributed in the diffusion layer, thereby ensuring the consistency of the optical diffusion performance of the diffusion film at all locations and improving the production quality of the diffusion film. However, when the coating processing device is coating the film, the film body is directly coated. After the film is transported, dust may adhere to the surface. Direct coating will affect the quality of the film coating process.

[0004] For example, the public document with application number: 202321400663.3 discloses a polymer diffusion membrane coating processing device. The utility model adopts three groups of coaxially arranged coating rollers to achieve uniformity and stability of coating effect, avoid local uneven coating or excessive or insufficient coating, and improve processing quality; reduce replacement and maintenance costs, reduce operating difficulty, and reduce use costs and operating difficulty; reduce the risk of wear and damage, extend service life, and improve use efficiency. However, although the device can replace three groups of different coating rollers during use, each coating roller will produce more or less wear after long-term use. Each coating roller still needs to be maintained and replaced, which only extends the service life of the coating mechanism and is also inconvenient to replace.

[0005] Therefore, in view of this, the existing structural deficiencies are studied and improved, and a matte film coating processing device is proposed. Utility Model Content

[0006] The purpose of the utility model is to provide a matte film coating processing device to solve the problems raised in the above background technology.

[0013] Preferably, positioning rollers are rotatably arranged on both left and right ends above the surface of the processing table, and the positioning rollers guide the matte film to pass through the middle of the conveying cavity so that the upper surface of the matte film can be in contact with the coating roller.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] 1. The utility model is provided with a coating mechanism, a driving motor, a driving gear, an elastic ball chuck, a transmission rod, a driven gear and a coating roller. The transmission rod applies force downward from the top to expand the elastic ball chuck. After the transmission rod is inserted into the elastic ball chuck, the shape of the elastic ball chuck will be restored to cover the transmission rod. At this time, the driven gear will mesh with the driving gear, and the coating roller can be assembled and used. The driving motor drives the driving gear to rotate, thereby engaging the driven gear to rotate, and the transmission rod is used to drive the entire coating roller to rotate for coating. The coating roller that has been used for a long time can be disassembled from the elastic ball chuck by directly pulling the transmission rod upward, which greatly improves the convenience of disassembly, assembly and replacement of the coating roller, reduces the disassembly and assembly steps, improves work efficiency, and ensures effective transmission after installation;

[0016] 2. The utility model is equipped with a dust removal mechanism, a hollow roller, a through port, a cotton fuzz pad and an electrostatic generating tube. Before coating, the matte film will pass through the hollow rollers at both ends of the conveying chamber. The matte film will preferentially contact the cotton fuzz pad to avoid friction and slip. The electrostatic generating tube is used to make the internal gas of the hollow roller carry static electricity. The static electricity is attached to the surface of the cotton fuzz pad through the through port. The cotton fuzz pad with static electricity will fully absorb the dust on the surface of the matte film to ensure the cleanliness of the surface of the matte film, thereby improving the coating quality of the matte film.

DETAILED DESCRIPTION

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] like Figure 1-Figure 2 As shown, a matte film coating processing device includes a processing table 1, a support rod 3 is fixedly installed on the right side of the upper middle part of the surface of the processing table 1, a coating mechanism 4 is arranged on the surface of the support rod 3, a fixing plate 5 is fixedly arranged on the left side of the upper middle part of the surface of the processing table 1, a conveying cavity 6 is horizontally opened in the middle of the surface of the fixing plate 5, and a dust removal mechanism 7 is arranged inside the conveying cavity 6.

[0024] By adopting the above technical solution, the coating mechanism 4 can be quickly disassembled and replaced, and maintain an effective transmission effect after installation to coat the matte film; the transmission chamber 6 enables the matte film to effectively contact and be transported by the dust removal mechanism 7.

[0025] Furthermore, the coating mechanism 4 includes a driving motor 401 fixedly installed in front of the surface of the front support rod 3 , and a driving gear 402 is provided at the rear end of the driving motor 401 .

[0026] By adopting the above technical solution, the driving motor 401 provides rotational force for the driving gear 402 .

[0027] Furthermore, the coating mechanism 4 also includes an elastic ball chuck 403 fixedly installed on the upper end of the support rod 3, and the elastic ball chuck 403 internally rotates and clamps the transmission rod 404; the opening of the elastic ball chuck 403 is smaller than the diameter of the transmission rod 404, and the internal bearing cavity can match the diameter of the transmission rod 404.

[0028] By adopting the above technical solution, the upper opening of the elastic ball chuck 403 can expand when stressed and restore when unstressed; the elastic ball chuck 403 is equipped with balls inside, so that after the transmission rod 404 is installed, the rotation friction is smaller and the rotation is more stable.

[0029] Furthermore, the coating mechanism 4 also includes a driven gear 405 fixedly mounted at the front end of the transmission rod 404 , the driven gear 405 is meshed with the driving gear 402 , and a coating roller 406 is fixedly disposed on the surface of the transmission rod 404 .

[0030] By adopting the above technical solution, the installed transmission rod 404 makes the driven gear 405 mesh with the driving gear 402, so that the driving gear 402 and the driven gear 405 provide the rotational force of the driving motor 401 to the coating roller 406 for coating.

[0031] Furthermore, positioning rollers 2 are rotatably arranged on both left and right ends above the surface of the processing table 1 , and the positioning rollers 2 guide the matte film to pass through the middle of the conveying cavity 6 , so that the upper surface of the matte film can be in contact with the coating roller 406 .

[0032] By adopting the above technical solution, the positioning roller 2 ensures the accuracy of the conveying position of the matte film and improves the stability of the matte film conveying process, thereby preventing the matte film from deviating and falling off.

[0033] like Figure 3-Figure 4 As shown, the dust removal mechanism 7 includes hollow rollers 701 rotatably arranged at corresponding upper and lower positions at the left and right ends of the inner surface of the conveying chamber 6, and the surface of the hollow roller 701 is evenly distributed with openings 702.

[0034] By adopting the above technical solution, the hollow roller 701 can further position the matte film transported inside the conveying cavity 6; the through hole 702 allows the static electricity inside the hollow roller 701 to be smoothly discharged.

[0035] Furthermore, the dust removal mechanism 7 also includes a cotton soft pad 703 fixed to the outer surface of the hollow roller 701 by Velcro, and an electrostatic generating tube 704 is provided on the inner surface of the hollow roller 701 for rotation via a ball bearing.

[0036] By adopting the above technical scheme, the matte film contacts with the cotton fuzz pad 703 preferentially in the conveying chamber 6, and the soft texture prevents the matte film from being scratched; the static electricity generating tube 704 will carry static electricity in the surrounding air, and the static electricity will adhere to the cotton fuzz pad 703, and the dust on the surface of the matte film can be absorbed by static electricity; the installation method of the cotton fuzz pad 703 and the hollow roller 701 allows the cotton fuzz pad 703 to be easily replaced after absorbing a large amount of dust.

[0037] Working principle: When using the matte film coating processing device, first, the transmission rod 404 is pressed down from the top to expand the elastic ball chuck 403. After the transmission rod 404 is inserted into the elastic ball chuck 403, the shape of the elastic ball chuck 403 will be restored to cover the transmission rod 404. At this time, the driven gear 405 will mesh with the driving gear 402, and the coating roller 406 can be assembled and used. The matte film passes through the middle of the left-end positioning roller 2, enters the transmission cavity 6, is located between the upper and lower hollow rollers 701, fits the cotton soft pad 703, and passes through the transmission cavity 6. The surface of the matte film will fit and contact with the coating roller 406, and finally pass through the middle of the right-end positioning roller 2. The coating process is part of the matte film processing process, so the subsequent processing will pull the guided matte film to move continuously. After the matte film is guided, the driving motor can be used The machine 401 drives the active gear 402 to rotate, thereby engaging the driven gear 405 to rotate, and the transmission rod 404 is used to drive the entire coating roller 406 to rotate for coating. Before coating, the matt film will pass through the hollow rollers 701 at both ends of the transmission chamber 6. The matt film will preferentially contact the cotton soft hair pad 703 to avoid friction and slip. The static electricity generating tube 704 is used to make the internal gas of the hollow roller 701 carry static electricity, and the static electricity is attached to the surface of the cotton soft hair pad 703 through the port 702. The cotton soft hair pad 703 with static electricity will fully absorb the dust on the surface of the matt film to ensure the cleanliness of the surface of the matt film, and then contact with the coating roller 406 for coating processing. The coating roller 406 that has been used for a long time can be disassembled from the elastic ball chuck 403 for maintenance or replacement by directly pulling the transmission rod 404 upwards. This is the working principle of the device for matt film coating processing.
