Description

Technical Field

[0001] This utility model relates to the field of decorative paper impregnation technology, and in particular to a device for uniformly impregnating and coating decorative paper. Background Technology

[0002] In the modern building materials production system, decorative paper, as a key material, is located beneath the surface paper in the product structure, providing a rich variety of patterns and designs and undertaking a vital decorative function. With the continuous progress of society, consumers have put forward higher requirements for the quality and aesthetics of building materials. The quality of decorative paper directly affects the texture of the end product. In order to meet market demand, manufacturers urgently need more advanced impregnation and coating equipment to improve the quality of decorative paper and thus enhance product competitiveness.

[0003] Early decorative paper impregnation relied on manual operation. Workers manually immersed the decorative paper into the glue tank and then used a scraper to spread the glue evenly on the paper surface. However, the efficiency was extremely low, and it was difficult to guarantee the uniformity of the glue application. Existing equipment uses an automated conveying and impregnation mode, which uses a traction device to move the decorative paper on the conveyor rollers so that it can complete the impregnation by passing through the box containing glue. This type of equipment has obvious defects. The equipment lacks a means to accurately control the glue thickness on the surface of the decorative paper. Often, there is too much glue in some areas and too little glue in others, which affects the improvement of the strength and toughness of the decorative paper and seriously restricts the quality of the finished decorative paper and production efficiency. Utility Model Content

[0004] To overcome the above deficiencies, this utility model provides a device for uniformly impregnating and coating decorative paper, aiming to improve the problem of the lack of precise control over the thickness of the adhesive on the surface of decorative paper in the prior art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a decorative paper uniform impregnation and coating device, including an adhesive tank, an impregnation mechanism is provided on the top of the adhesive tank for impregnating adhesive, an adhesive scraping mechanism is provided on the outer wall of the adhesive tank for uniformly scraping adhesive, and an adjustment mechanism is provided on the top of the adhesive scraping mechanism.

[0006] The dipping mechanism includes an upper guide roller, which is disposed at the top of the glue tank. A dipping roller is disposed at the bottom of the glue tank. A motor is disposed on the outer wall of the glue tank. A central shaft is fixedly connected to the output end of the motor. A gear is fixedly connected to the outer wall of the central shaft. An applicator is disposed on the outer wall of the central shaft.

[0007] As a further description of the above technical solution:

[0008] The adhesive scraping mechanism includes a base plate, a support assembly on the outer wall of the base plate, an adhesive scraping assembly on the outer wall of the support assembly, a gantry frame on the outer wall of the base plate, a clearance assembly on the top of the adhesive scraping assembly, and a pressing assembly on the top of the clearance assembly.

[0009] As a further description of the above technical solution:

[0010] The applicator includes a lower pressure roller, which is fixedly connected to the outer wall of the lower central shaft, and an applicator roller is fixedly connected to the outer wall of the upper central shaft.

[0011] As a further description of the above technical solution:

[0012] The support assembly includes a support frame, which is fixed to the outer wall of the base plate, and a rotating column is rotatably connected to the middle of the support frame.

[0013] As a further description of the above technical solution:

[0014] The adhesive scraping assembly includes a scraper, which is disposed on the inner wall of the rotating column, and the rotating column is provided with bolts.

[0015] As a further description of the above technical solution:

[0016] The clearance component includes a limiting block fixed to the top surface of the scraper, and a slider is provided on the inner wall of the limiting block.

[0017] As a further description of the above technical solution:

[0018] The clamping assembly includes a pressing column, the bottom of which is rotatably connected to the top surface of the slider, and a limiting block is fixedly connected to the top surface of the pressing column. A spring is provided on the outer wall of the limiting block.

[0020] The adjusting mechanism includes a synchronizing rod, the two ends of which are slidably connected to the outer wall of the extrusion column. The inner wall of the synchronizing rod is provided with a threaded rod, and the outer wall of the threaded rod is provided with a threaded sleeve. The bottom surface of the threaded rod is rotatably connected to the top surface of the gantry.

[0021] This utility model has the following beneficial effects:

[0022] 1. In this utility model, during the impregnation process, the decorative paper passes through the top of the upper guide roller, then through the bottom of multiple impregnation rollers, and finally passes through the middle of the coating roller and the lower pressure roller. The motor drives the upper central shaft to rotate. Gears are fixedly connected to the outer walls of the two central shafts, and the two gears mesh, causing the lower pressure roller and the coating roller to rotate in opposite directions, conveying the decorative paper to the subsequent process. The outer wall of the coating roller is designed to ensure that the adhesive is evenly distributed on the decorative paper, while squeezing out excess adhesive.

[0023] 2. In this utility model, the decorative paper passes from the top of the base plate and the bottom of the scraper. The scraper removes excess glue from the surface of the decorative paper, making the glue more even. By rotating the threaded sleeve, the synchronizing rod is pressed down. The two ends of the synchronizing rod are pressed down by springs, and the pressure is transmitted to the slider. The slider presses down one end of the scraper, so that the bottom of the scraper presses the surface of the decorative paper tightly. This method can adapt to decorative paper of various specifications. Attached Figure Description
