[0002] The surface coating of drawing paper is mainly used to change the surface characteristics of drawing paper to meet specific application requirements. The main functions of the coating are as follows: making the drawing paper better accept ink and be easy to print, preventing dirt, increasing the ink adhesion, and preventing the printed graphics and texts from falling off. The coating can also serve as a protective layer for the drawing paper, improving its durability and abrasion resistance.

[0003] The patent document with the publication number CN209493760U discloses a glazing machine for drawing paper, which includes a coating device and a calendering device. The coating device includes two coating rollers placed opposite to each other. The two coating rollers are arranged oppositely and there is a gap between them as a paper passage. A spray gun is arranged on the side of the coating roller opposite to the paper passage; the calendering device includes a pressing roller and a calender roll arranged above the pressing roller. The pressing roller has a circular outer surface and a hollow inner cavity. An arc-shaped notch is arranged above the outer surface of the pressing roller. A lifting device is arranged in the hollow inner cavity of the pressing roller. After the lifting device lifts the pressing roller, the arc-shaped notch on the upper surface of the pressing roller fits with the lower end of the calender roll.

[0004] Although the above glazing machine for drawing paper can solve the corresponding technical problems, during use, when coating the surface of the drawing paper with paint, it is easy to cause the coating on the surface of the drawing paper to be uneven, and it is not easy to recycle the excess paint. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a device for preparing the surface coating of drawing paper, so as to solve the technical problems that the existing device causes uneven coating and non-recyclable paint when coating the surface of the drawing paper.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A device for preparing the surface coating of drawing paper, including a bottom plate.

[0009] The coating mechanism is arranged to install a coating roller on the U-shaped frame one, and a plurality of coating nozzles are evenly installed on the top of the U-shaped frame one. Connect the coating nozzles to the coating tank. The coating nozzles spray materials onto the coating roller, so that the coating roller coats the tracing paper with the coating. The coating roller abuts against the tracing paper, which has a compaction effect to ensure that the coating can be evenly coated on the surface of the tracing paper.

[0010] As a preferred embodiment of the present utility model, one end of the coating roller penetrates through the U-shaped frame one and is installed with a pulley one. The pulley one is connected to a pulley two through a belt. The pulley two is installed on the output shaft of the motor, and the motor is fixed on the top of the bottom plate.

[0011] The motor rotates to drive the pulley two to rotate, so that the power is transmitted to the pulley one through the belt, thereby driving the coating roller to rotate, and the coating roller evenly coats the surface of the tracing paper.

[0012] As a preferred embodiment of the present utility model, the scraping mechanism includes a U-shaped frame two, which is fixedly connected to the bottom plate. Grooves are respectively opened on the opposite surfaces of the two side feet of the U-shaped frame one. Slide bars are fixedly connected in the grooves.

[0013] By adopting the above technical solution, the scraping mechanism is set, and a triangular scraping plate is installed between the two slider twos, so that the triangular scraping plate abuts against the tracing paper, thereby scraping off the excess coating on the tracing paper, making the coating more evenly coated on the tracing paper. By installing a spring between the slider one and the slider two, using the elastic working ability of the spring, the triangular scraping plate can be dynamically adjusted, and further enables the triangular scraping plate to more stably scrape the tracing paper.

[0014] As a preferred embodiment of the present utility model, a screw rod is screwed in the middle of the U-shaped frame two. One end of the screw rod is connected to the top of the cross bar through a bearing, and the other end of the screw rod is installed with a hand wheel.

[0015] By adopting the above technical solution, one end of the screw is fixedly connected to the inner ring of the bearing, and the outer ring of the bearing is fixed on the top of the cross bar. By rotating the hand wheel, the cross bar is driven to rotate on the second U-shaped frame, and then the cross bar is driven to move up and down on the surface of the sliding rod. In cooperation with the spring, the elastic capacity of the spring can be adjusted, so that the triangular scraping plate can better abut against the tracing paper for scraping operation.

[0016] As a preferred solution of the present utility model, transmission platforms extend out from both sides of the triangular scraping plate, and collection boxes are respectively arranged below both sides of the triangular scraping plate. The collection boxes are fixedly installed on the top of the bottom plate.

[0017] By adopting the above technical solution to set the collection box, the redundant paint scraped by the triangular scraping plate is collected into the collection box, so as to effectively recycle the paint, reduce the waste of paint, and thus save the production cost.

[0018] Compared with the prior art, the beneficial effect of the device for preparing the surface coating of tracing paper of the present utility model lies in that: the transmission platform, the paint mechanism and the scraping mechanism arranged on the top of the bottom plate cooperate with each other to evenly coat the paint on the surface of the tracing paper and recycle the redundant paint, so as to reduce the waste of paint and thus greatly save the production cost.

The coating mechanism 4 and the scraping mechanism 5 are used in cooperation with the transfer table 2, and a tracing paper 3 is abutted between the coating mechanism 4, the scraping mechanism 5 and the transfer table 2.

[0030] The transfer table 2 is common general knowledge in the art and will not be elaborated here.

[0031] The coating mechanism 4 includes a U-shaped frame one 401, and the U-shaped frame one 401 is fixedly connected to the bottom plate 1. A coating roller 402 is rotatably connected to the middle of the U-shaped frame one 401. A tracing paper 3 is abutted between the coating roller 402 and the transfer table 2. A plurality of coating nozzles 403 are evenly installed on the top of the U-shaped frame one 401. By setting the coating mechanism 4, the coating roller 402 is installed on the U-shaped frame one 401, and a plurality of coating nozzles 403 are evenly installed on the top of the U-shaped frame one 401. The coating nozzles 403 are connected to the coating tank. The coating nozzles 403 spray materials on the coating roller 402, so that the coating roller 402 coats the coating on the tracing paper 3. The coating roller 402 abuts against the tracing paper 3, which has a compaction effect to ensure that the coating can be evenly coated on the surface of the tracing paper 3.

[0032] One end of the coating roller 402 penetrates through the U-shaped frame one 401 and is installed with a pulley one 404. The pulley one 404 is connected to a pulley two 406 through a belt 405.
