Description

Technical Field

[0001] The utility model relates to the technical field of anti - scratching devices for paper cup machines, and particularly relates to an anti - scratching device applied to a paper cup machine. Background Art

[0002] A paper cup machine is a machine that mechanically processes and bonds original paper to make paper containers. In the prior art, when a paper cup machine produces double - sided PE - coated paper cups, the main technological process is: feeding the body paper, feeding the bottom paper, combining the body and bottom papers, heating the bottom, folding the bottom, rolling the pattern on the bottom, curling the mouth, and discharging the cup.

[0003] Among them, the process of rolling the pattern on the bottom mainly rolls the inner wall of the cup feet at the bottom of the paper cup into a shape with inclined lines. During this process, the paper cup rotates at a high speed, which may scratch the outer layer of PE or the printed surface at the bottom of the paper cup, resulting in damage to the paper cup. At the same time, during the production of paper cups, there are often phenomena where hard objects scrape against the inner wall of the paper cup. Without anti - scratching ability on the inner wall of the paper cup, it will lead to damage to the paper cup, causing waste of resources.

[0004] The Chinese utility model patent with the application number 202221426642.4 discloses an anti - scratching device for a paper cup machine. Although this utility model immerses the anti - scratching agent of the first oil box into the brush through a communication chamber, and the rotating motor drives the oil - applying mechanism to rotate through a rotating rod, so that the anti - scratching agent is evenly applied to the curling part at the bottom of the paper cup. At the same time, the second oil box passes the anti - scratching agent into the spray pipe through a water pump, and finally it is evenly sprayed on the inner wall of the uniformly rotating paper cup by a spray head, simultaneously performing anti - scratching treatment on the curling part at the bottom of the paper cup and the inner wall of the paper cup, preventing the paper cup from being scratched and rendered unusable, and avoiding waste of resources. However, after long - term use, the brush of this utility model will wear, and it is not convenient to quickly replace the brush. Summary of the Utility Model
