[0021] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0022] like Figure 1 As shown, a varnish coating device for composite cardboard includes a base plate 1, a support frame 2 is installed on one side of the upper surface of the base plate 1, side plates 3 are installed on both sides of the upper surface of the base plate 1, a conveying mechanism 4 is arranged between the two side plates 3, a coating mechanism 5 is arranged on one side of the conveying mechanism 4, and a material receiving table 6 is also installed on one side of the upper surface of the base plate 1.
[0023] like Figure 3 、 Figure 4 As shown, the conveying mechanism 4 includes a servo motor 401, which is installed on a side surface of one of the side plates 3. A conveying roller 402 is installed at the output end of the servo motor 401. One end of the conveying roller 402 is rotatably set on a side surface of one of the side plates 3. A limiting roller 403 is rotatably installed between the two side plates 3 and above the conveying roller 402.
[0024] The servo motor 401 drives the conveying roller 402 to rotate, and the top limiting roller 403 is rotated to convey the jammed paper, which is more convenient during use.
[0025] like Figure 2 、 Figure 4As shown, the coating mechanism 5 includes a connecting rod 501, which is installed on the top of one side surface of each side plate 3, and a top plate 502 is installed at the end of the connecting rod 501. Several nozzles 503 are evenly distributed on one side of the lower surface of the top plate 502. A mounting plate 504 is also movably installed on one side of the lower surface of the top plate 502. Blocks 5041 are installed on both sides of the upper surface of the mounting plate 504, and slots 5021 that cooperate with the block 5041 are provided on both sides of the lower surface of the top plate 502. Brushes 505 are evenly distributed on the lower surface of the mounting plate 504.
[0026] During the transportation of the paper jam, the varnish can be sprayed through the nozzle 503, and the surface of the paper jam can be brushed by the brush 505, so that the varnish coating is more uniform and the use effect is better. Through the cooperation between the block 5041 and the card slot 5021, the mounting plate 504 can be movably installed, which facilitates the replacement of the brush 505.
[0027] like Figure 3 、 Figure 4 As shown, a groove 601 is provided on the surface of one end of the material receiving table 6, and a collection frame 602 is movably installed inside the groove 601. A plurality of through holes 603 are provided through the upper surface of the material receiving table 6, and a handle 6021 is installed on the surface of one end of the collection frame 602.

[0029] The working principle of the varnish coating device for composite cardboard:
[0030] When in use, the paper jam is placed on the support frame 2, and one end of the paper jam is placed between the conveying roller 402 and the limiting roller 403. The conveying roller 402 is driven to rotate by the servo motor 401, and the limiting roller 403 is rotated. The rotation of the conveying roller 402 can convey the paper jam. When it is conveyed to the bottom of the nozzle 503, the surface of the paper jam is sprayed with varnish through the work of the nozzle 503. After spraying, the paper jam is continued to be conveyed. When the paper jam passes under the brush 505, the brush 505 will brush the varnish on the surface of the paper jam. The distance between the brush 505 and the upper surface of the paper jam is fixed. In the process of conveying the paper jam, the position with larger surface varnish thickness will be brushed by the brush 505, so that the varnish coating on the surface of the paper jam is more uniform. After brushing by the brush 505, the excess varnish will fall through the through hole 603 to the inside of the collection frame 602 for collection and recycling, which can effectively reduce the waste of raw materials.
[0031] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is impossible to list all implementation methods here. All obvious changes or modifications derived from the technical solution of the present invention are still within the scope of protection of the present invention.
