Problems solved by technology

[0002] In the processing of PVC electrical tape, the PVC calender process is an important link, which requires high efficiency and precise work. This is a characteristic of the PVC calender, and the PVC calender needs to ensure that the tape cannot be skewed when it is working. Now The best way is to fine-tune the rollers, but the deflection is not easy to control in time, and it is often scrapped due to serious deflection, and a little deflection will affect the processing effect of the product. How to accurately and timely correct the deflection of the PVC calender roller and improve work efficiency is a must. At present, the technical problem of PVC calender has been studied, and it is also the purpose of researchers to continuously improve PVC calender.
