Description

Technical Field

[0001] The utility model relates to the technical field of abrasive cloth production, and particularly relates to a cloth storage machine. Background Art

[0002] In the pretreatment process of abrasive cloth production, when changing rolls, the machine needs to be stopped, which will cause a stop mark on the cloth base, resulting in certain quality problems such as uneven and inconsistent scraping amounts. Therefore, a cloth storage machine is needed to temporarily store the cloth base, so as to avoid the above problems caused by stopping during roll change.

[0003] During the actual use of the cloth storage machine, the speed control of the cloth storage machine is the key to cloth storage. Generally, the speed matching between rotating rollers can be achieved through calculated parameters, and the lifting of the cloth storage rack can achieve speed matching through calculating the reduction ratio and parameter setting. However, during the stage from zero speed to speed matching at the moment when the cloth storage rack starts and descends, the cloth base lacks buffering, resulting in unstable tension, and thus the cloth base becomes slack during the cloth storage process.
