Description

Technical Field

[0001] This utility model relates to the field of fabric coating technology, specifically to an apparatus for coating automotive interior fabrics. Background Technology

[0002] Automotive interior fabrics are the fabrics used to wrap inside car parts in the automotive interior products industry. During the production process, a special coating with special functions needs to be applied to the fabric to give the fabric certain good protective properties after film formation, such as oil resistance, water resistance, flame retardancy, water resistance, abrasion resistance, and improved feel, resulting in a full and thick appearance.

[0003] The automotive interior fabric coating device disclosed in patent number "CN219463865U" includes a housing, a motor, a connecting rod, rollers, a placement frame, and a baffle plate. The motor is mounted on the front side of the housing, and the connecting rod is connected to the output shaft of the motor. Rollers are mounted on the connecting rod. A baffle plate is fixedly connected inside the housing and penetrates through the housing. A placement frame is provided on the upper part of the housing and is fixedly connected to the baffle plate. By pouring paint into the placement frame, the paint flows onto the rollers, and the rollers apply the paint to the fabric, which facilitates the coating of the fabric and can improve the work efficiency of the workers.

[0004] However, the above-mentioned device still has the following problems during implementation:

[0005] 1. Traditional coating equipment mostly uses a drive motor to rotate the discharge roller, pulls out the fabric on the feed roller, and coats the fabric with paint through the coating roller. Finally, the discharge roller collects the paint. This structure is relatively simple and lacks a scraper structure that can match the coating roller. During coating, the pigment on the fabric surface is not uniform enough, and it cannot accurately adhere and scrape the pigment on the fabric surface according to the coating thickness.

[0006] 2. Most existing coating rollers are set as fixed structures. A single coating roller, together with a discharge pipe, coats the fabric surface. The amount of coating material discharged from the discharge pipe is difficult to control, and there may be lumps or particles. The coating pigment comes into direct contact with the fabric, resulting in poor coating effect. Furthermore, uneven coating amount will cause poor waterproof effect in some areas, and the finished product is prone to leakage. Utility Model Content

[0019] 2. The coating scraper assembly is designed to work with the coating roller assembly. When the coated automotive interior fabric is conveyed to the bottom of the coating scraper assembly, it is smoothed and trimmed by the scraper. The threaded rod allows for easy adjustment of the scraper's rise and fall. The scraper's working height can be adjusted according to different coating parameters to facilitate more precise application and trimming, and increase uniformity.

[0020] 3. The feed cylinder is connected to the feed pipe. The bottom of the feed cylinder is equipped with a conical discharge cylinder to facilitate feeding the material into the feed pipe. The feed cylinder can store a certain amount of pigment to replenish the feed pipe.

[0035] Based on Embodiment 1, this embodiment details the coating roller assembly 7 in Embodiment 1. The coating roller assembly 7 includes a feeding roller 701 and a coating roller 702. The feeding roller 701 is positioned above the coating roller 702 and fitted to it. One side of the feeding roller 701 is fixedly connected to a first rotating shaft 10 via a solid baffle 9. The other side of the feeding roller 701 is connected to a feed pipe 11, one end of which extends into the interior of the feeding roller 701.

[0038] Working principle: During use, the fabric to be coated is conveyed by the conveyor frame 2. The coating roller assembly 7 on the upper surface of the conveyor frame 2 coats the fabric surface. The feeding roller 701 of the coating roller assembly 7 is matched with the coating roller 702. The feeding roller 701 feeds the fabric. The surface of the feeding roller 701 and the surface of the feeding pipe 11 are provided with small holes to facilitate the leakage of the coating pigment. The coating pigment falls evenly onto the outer surface of the coating roller 702 and then comes into even contact with the fabric surface conveyed by the upper surface of the conveyor belt 201, which improves the uniformity of coating.

[0039] The coating scraper assembly 8 is designed to work in conjunction with the coating roller assembly 7. When the coated automotive interior fabric is conveyed to the bottom of the coating scraper assembly 8, it is smoothed and trimmed by the scraper 802. The threaded rod 20 allows for easy adjustment of the scraper 802's rise and fall. The working height of the scraper 802 can be adjusted according to different coating parameters to facilitate more precise application and trimming, increasing uniformity. The feed cylinder 17 is connected to the feed pipe 11. The bottom of the feed cylinder 17 is equipped with a conical discharge cylinder 19 to facilitate uniform feeding into the feed pipe 11. The feed cylinder 17 can store a certain amount of pigment to replenish the feed pipe 11. Through the evenly distributed small holes on the feed pipe 11 and the coating roller 702, the pigment discharged during coating passes through the sieve through the discharge hole 12, which is less likely to produce a large number of particles and lumps, resulting in smoother and more uniform pigment coating and improved quality of the finished product.

[0040] It should be noted that the drive motor 202, coating roller 702, feed pipe 11, motor 13 and feed cylinder 17 are existing devices or equipment, or devices or equipment that can be implemented by existing technology. Their power supply, specific composition and principle are clear to those skilled in the art, so they will not be described in detail.
