[0002] Melamine impregnated paper, also known as melamine impregnated film paper or melamine paper, is a material used for the surface decoration of artificial boards. It is made of plain base paper or printed decorative paper that is impregnated with amino resin (such as melamine formaldehyde resin and urea-formaldehyde resin) and dried to a certain degree, and then glued to the base material of the artificial board through a hot pressing process. Melamine impregnated paper usually needs to be glued during processing, so a special gluing device is used.

[0028] The cleaning assembly includes a fixed bar 401 fixedly connected to one side of the baffle 201, a scraper 402 for removing glue adhered to the surface of the baffle 201 is arranged below the fixed bar 401, two groups of movable rods 403 are symmetrically fixedly connected to the top of the scraper 402, and the movable rods 403 are slidably connected to the fixed bar 401, the top of the movable rod 403 is rotatably connected to the roller 404 through the mounting seat, the outer sleeve of the movable rod 403 is provided with a spring 2 405 and the two ends of the spring 2 405 are respectively fixedly connected to the fixed bar 401 and the mounting seat, four groups of guide rails 406 are symmetrically fixedly connected to the bracket through a connecting fixing bracket, and a tilting block 407 is fixedly connected to the guide rail 406, and the length of the scraper 402 is consistent with the length of the baffle 201.

[0029] The implementation principle of a device for precise gluing of impregnated paper in the embodiment of the present application is as follows: first, the impregnated paper is conveyed by the conveying roller 2, and then the servo motor 204 is started, and the bidirectional screw rod 203 is driven to rotate by the servo motor 204, and the threaded connection between the threaded block 202 and the bidirectional screw rod 203, and the sliding cooperation between the guide block 207 and the guide rod 208, so that the two sets of baffles 201 can be driven to accurately approach the impregnated paper and contact its side. In this way, when the impregnated paper is glued, the glue will not flow to the surface of the platform 1 through the obstruction of the baffle 201, thereby avoiding the waste of glue, and when driving the two sets of baffles In the process of moving toward each other, the two groups of sealing pistons 205 fixedly connected to the baffle plate 201 through the connecting frame 206 can also be driven to move toward each other in the upper glue tube 103, so that the glue discharge range can be adjusted to avoid the problem of glue waste caused by too large a glue discharge range. At the same time, in the process of driving the two groups of baffle plates 201 to move toward each other, the vertical rod 303 and the hinged action between the movable bar 302 and the connecting rod 304 can be used to push the movable bar 302 to move vertically downward, thereby driving the pressure bar 301 movably connected to the movable bar 302 to move vertically downward to press down and fix the two sides of the impregnated paper, thereby preventing the impregnated paper from curling and affecting The gluing situation occurs, which ensures the processing quality of the impregnated paper. When the pressure strip 301 contacts the impregnated paper, the sliding cooperation between the connecting rod 305 and the movable bar 302 and the elastic effect of the spring 1 306 itself can play a certain buffering role, so that the movable bar 302 can continue to move downward until the baffle 201 contacts the side of the impregnated paper. At the same time, in the process of driving the two sets of baffles 201 to move toward each other, the roller 404 can also be driven to move together. When the roller 404 rolls down from the inclined block 407, the rebound effect of the spring 2 405 and the sliding cooperation between the movable rod 403 and the fixed bar 401 are utilized to make the scraper 402 will vertically rise to the highest point, and then start the glue delivery pump 102. The glue delivery pump 102 can deliver the glue in the glue storage tank 101 to the glue pipe 103 and discharge it through the glue outlet head, thereby achieving the purpose of gluing, and then continue to transport the impregnated paper. After the gluing is completed, the servo motor 204 is finally controlled to reverse to reset the baffle 201. At this time, the roller 404 will roll to the inclined surface of the inclined block 407 again. In this way, the scraper 402 will move vertically downward to scrape off the glue adhering to the baffle 201, thereby achieving the purpose of automatically cleaning the baffle 201. The staff can collect the scraped glue in a unified manner. Example 2
