Description

Technical Field

[0001] The present application relates to the technical field of decorative paper coating, and in particular to a decorative paper coating device. Background Art

[0002] Decorative paper is an essential raw material in many building materials, such as low- and high-pressure boards used in furniture and cabinets, as well as fireproof boards and flooring. Within the product structure, decorative paper primarily serves to provide decorative patterns and a covering function to prevent the underlying adhesive from seeping through. This layer requires the paper to possess excellent hiding power, impregnation, and printing properties. Decorative paper requires a smooth surface, good absorbency, and adaptability. Base colors require a uniform hue, while colored materials require vibrant colors.

[0003] "Decorative paper coating" refers to the process of coating the surface of decorative paper. Through the coating process, a specific coating (such as a mixture of resin, pigment, additives, etc.) is evenly applied to the surface of the decorative paper to achieve the purpose of improving the performance and appearance of the decorative paper.

[0004] For example, the patent with publication number CN219631748U specifically discloses a coating roller device of a coating machine, including a base, a transmission roller, a slide, a collection box, a handle, a reduction motor, a screw, a bracket, a drive motor, a coating roller and a heater, so that the coated fabric can be dried and the position of the coating roller can be adjusted at the same time.

[0005] After finishing decorative paper, its surface is covered with dust, impurities, oil, and other contaminants. However, the aforementioned patented coating device does not clean the decorative paper before coating. This results in uneven coating due to the unclean surface. Contaminants on the decorative paper surface hinder the uniform distribution of the coating, leading to inconsistent coating thickness. Furthermore, spots, bubbles, or blemishes may form on the coated surface, affecting the appearance quality of the decorative paper. Therefore, a decorative paper coating device is needed to address these issues.

[0006] It should be noted that the above information disclosed in this Background section is only for understanding the background technology of the present application concept, and therefore, it may contain information that does not constitute the prior art. Summary of the Invention

[0024] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0025] In order to enable those skilled in the art to better understand the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of this application.

[0026] like Figures 1-4 As shown, the present application provides a decorative paper coating device, comprising a base 1, a mounting frame 101 fixedly mounted on the base 1, and a plurality of auxiliary transmission rollers 102 rotatably mounted on the mounting frame 101, the auxiliary transmission rollers 102 being used to restrict the decorative paper and keep it taut;

[0027] A coating assembly 2 is mounted on the mounting frame 101. The coating assembly 2 is used to coat the decorative paper. The coating assembly 2 includes two sets of L-shaped frames 201 fixedly mounted on one side of the mounting frame 101. A main drive roller 202 is connected between the two sets of L-shaped frames 201.

[0028] An adjustment assembly 3 is mounted on the L-shaped frame 201. The adjustment assembly 3 includes a concave rod 301 fixedly mounted on the L-shaped frame 201. A drive motor 302 is fixedly mounted on one end of the concave rod 301. A screw rod 303 is fixed to the output end of the drive motor 302. The other end of the screw rod 303 is connected to the other end of the concave rod 301 by a bearing.

[0029] A screw sleeve 304 is threadedly connected to the screw 303. A support rod 204 is connected between the two sets of screw sleeves 304. A coating roller 203 is mounted on the support rod 204. A rotary motor (not shown in the figure) is also mounted on the support rod 204. The output end of the rotary motor is connected to the coating roller 203. The rotary motor is used to drive the coating roller 203 to rotate so as to coat the decorative paper on the main drive roller 202.

[0030] The screw rod 303 is adapted to rotate along with the output end of the driving motor 302, so that the screw rod sleeve 304 moves linearly on the screw rod 303, thereby moving the coating roller 203 closer to or farther from the main driving roller 202, so as to be suitable for coating decorative papers of different thicknesses;

[0031] A suction assembly 4 is mounted on the mounting frame 101. The suction assembly 4 is used to remove dust from the upper and lower surfaces of the decorative paper. The suction assembly 4 includes a support frame 401 fixedly mounted on the mounting frame 101. Connecting rods 402 are mounted on both ends of the inner wall of the support frame 401. A sliding rod 403 is fixedly mounted on one end of the connecting rod 402.

[0032] Two sets of fixing seats 404 are fixedly installed at one end of the slide rod 403. A bidirectional screw 405 is rotatably installed on one set of fixing seats 404, and one end of the bidirectional screw 405 is connected to the bearing of the other set of fixing seats 404. Two sets of slide seats 406 are threadedly connected to the bidirectional screw 405. A mounting plate 408 is fixedly installed on the slide seat 406. A joint 409 is installed through the mounting plate 408. An exhaust head 410 is connected to one end of the joint 409. The joint 409 is suitable for connecting to an air supply device to generate negative pressure at the exhaust head 410 and collect dust on the surface of the decorative paper.

[0033] A turntable 407 is fixedly mounted on one end of the bidirectional screw 405, and the turntable 407 facilitates holding and rotating the bidirectional screw 405;

[0034] Working principle:

[0035] The user can move and transport the fabric through the auxiliary drive roller 102 and the main drive roller 202, and then coat the fabric on the auxiliary drive roller 102 and the main drive roller 202 through the coating roller 203. When the position of the coating roller 203 needs to be adjusted, the user can drive the screw rod 303 to rotate by the driving motor 302, and the rotation of the screw rod 303 drives the screw rod sleeve 304 to move, thereby achieving the effect of adjusting the distance between the coating roller 203 and the main drive roller 202;

[0036] At the same time, air can be supplied to the exhaust head 410 through an external air blowing device to remove dust and impurities on the upper and lower surfaces of the decorative paper. When coating decorative papers of different thicknesses, the bidirectional screw 405 is rotated by holding the turntable 407, so that the two sets of slides 406 slide on the bidirectional screw 405 and move away from or towards each other until the adjustment is appropriate.

[0037] The above are merely preferred embodiments of the present application and are not intended to limit the present application. Those skilled in the art will readily appreciate that various modifications and variations are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
