Description

Technical Field

[0001] The utility model belongs to the technical field of guide and limiting rollers for paper material production, and relates to a limiting roller structure with an automatic lifting function. Background Art

[0002] In the paper production process, the limit guide roller plays a vital role. It is responsible for controlling the position and movement direction of the paper on the production line to ensure that the paper can pass through each process stably and accurately. Since the paper needs to be continuously transported on the production line, the limit roller can effectively guide and limit the movement trajectory of the paper through its design and structure to prevent it from deflecting or curling. However, if the limit guide roller cannot be raised or lowered, it will cause a series of problems, seriously affecting the efficiency and quality of paper production.

[0003] The inability of the limit guide roller to rise and fall will result in the paper being unable to adapt to different tension levels during the transmission process. During the production process, the tension of the paper may vary due to process requirements or raw material differences. If the limit guide roller cannot be raised and lowered according to the tension of the paper, it will not be able to effectively clamp and transmit the paper, which may cause the paper to deviate, wrinkle or even tear during the transmission process, seriously affecting the product quality. Therefore, a limit roller structure with an automatic lifting function is urgently needed to solve the above problems. Utility Model Content
