Description

Technical Field

[0001] The utility model relates to the technical field of paper cup processing, in particular to spraying equipment for anti-leakage coating of paper cups. Background Art

[0002] The anti-leakage coating for paper cups is an important process in the paper cup manufacturing process. It can effectively prevent liquid from leaking from the inside of the paper cup, improving the performance of the paper cup and user experience. The main materials used for the anti-leakage coating for paper cups include polyethylene, polyethyl polyacrylate, etc.

[0003] The utility model patent with authorization publication number CN202410152106.7 discloses a coating device for paper cup production. The coating device includes a base, with a drive box mounted at one end of the top of the base. A coating drive mechanism and a coating spray mechanism are mounted within the drive box. The coating drive mechanism is connected to the coating spray mechanism and drives the coating spray mechanism to extend from the bottom of the drive box and insert into the inner wall of the paper cup to spray the inner wall of the paper cup. When coating the inner wall of the paper cup, the drive motor drives the partially active bevel gear to rotate, which in turn drives the first driven bevel gear, the gear assembly, and the second driven bevel gear to rotate. This allows the spray pipe to be inserted into the inner wall of the paper cup, rotated along the inner wall of the paper cup to spray uniformly, and finally slid out of the paper cup, achieving automatic and uniform spraying of the inner wall of the paper cup. The entire spraying process can be achieved by only one drive motor, greatly reducing the production cost of the equipment. At the same time, the overall workflow of the equipment is realized by the meshing transmission between the gears, facilitating daily maintenance of the equipment.

[0004] Although the coating device used in paper cup production is conducive to automatic and uniform spraying on the inner wall of the paper cup, the device still has the following problems in actual use: during the spraying process, the coating produced by the spraying will diffuse into the air. As the paper cups are continuously sprayed, a large amount of coating will diffuse into the working area, which will cause regional environmental pollution. In view of this, we propose a spraying device for paper cups with anti-leakage coating. Utility Model Content

The movable plate 47 is lowered, the fixed shaft 42 is rotatably connected to the movable plate 47, and the end of the piston rod of the electric cylinder 23 is fixed to the movable plate 47; a spray part 3 is provided above the supporting plate 40, and the spray part 3 includes a shell 30 with an open bottom, two drying lamp tubes 32 are fixed on the inner top of the shell 30, and a moisture-absorbing layer 31 is installed on the inner walls of both sides of the shell 30, a liquid pump 33 is installed on the top of the shell 30, a liquid inlet pipe 34 is installed at the liquid inlet of the liquid pump 33, and a drain pipe 35 is installed at the liquid outlet of the liquid pump 33, the end of the drain pipe 35 penetrates into the shell 30 and is fixed with a horizontal pipe 36, a plurality of vertical pipes 37 are fixed below the horizontal pipe 36, and a nozzle 38 is fixed at the bottom of the vertical pipe 37.

[0030] In this embodiment, the plurality of nozzles 38 are linearly and evenly spaced, and the nozzles 38 are located directly above the corresponding fixing holes 410. This design facilitates the nozzles 38 to be inserted into the openings of the paper cups in the fixing holes 410, thereby facilitating uniform spraying of the inner wall of the paper cups.

[0031] In this embodiment, a strip groove 20 is formed on the front surface of the vertical plate 2, and a guide rod 21 is fixed in the strip groove 20. The guide rod 21 passes through the movable plate 47 and is slidably connected to the movable plate 47.

[0032] In this embodiment, a support plate 22 is fixed to the front end of the vertical plate 2, and the electric cylinder 23 is fixedly connected to the support plate 22 by bolts.
