The position and structure of the sealing baffle 505 correspond to those of the hot melt nozzle 4, and the sealing baffle 505 is controlled to block the hot melt nozzle 4 to prevent the residual glue from dripping (Hot melt adhesives have high viscosity and poor fluidity. With the design of the present utility model, residual glue dripping can be completely prevented.), on the one hand, it can avoid the waste of the glue, and on the other hand, it can also avoid the products that are not removed in time from being contaminated by the dripping glue.

[0029] Specifically, a positioning slider 506 is fixedly connected to the top of the pushing plate 504. The positioning slider 506 is slidably connected to a positioning chute 507, and the positioning chute 507 is fixed to the bottom of the metal steel sleeve 2.

[0030] Furthermore, the cleaning assembly 6 includes a mounting plate 601 fixedly connected to the protective shell 3. A secondary motor 602 is mounted on the top of the mounting plate 601. The output end of the secondary motor 602 is connected to a rotating rod 603. The bottom end of the rotating rod 603 penetrates through the mounting plate 601 and is connected to a wiping cotton block 604. When the end of the sealing baffle 505 moves and blocks the hot melt nozzle 4, glue will adhere to it. Rely on the cleaning assembly 6 to wipe off the glue at the end of the sealing baffle 505 to prevent the glue from adhering to other positions.

[0031] Still further, the wiping cotton block 604 consists of a sponge sleeve 6041, a sleeve 6042, and a positioning rod 6043. The sponge sleeve 6041 is fixed on the outside of the sleeve 6042.
