What is the main cause of leather sprocter coiling abrasion?

In the process of longitudinal shearing of the leather sundering machine equipment, if the steel coil is rolled in a loose state, then the internal layers of the steel coil will slide. In this way, it may lead to a variety of scratches on the surface of the steel plate, as well as scratches on the point of repeated conflict. In fact, in the running process of the leather slabbing machine equipment, even the normally coiling steel coil will be scraped when it is coiling beyond the normal tension. According to the production experience to analyze, which mainly includes the following three conditions:

Scrape caused by improper setting of uncoiler. The main conditions are as follows: in the process of operating the leather sasser, the reverse tension added by the uncoiler exceeds the coiling tension of the base material, or the lack of brake added by the uncoiler, or the lack of pressure of the stop roll of the uncoiler will cause the steel coil to relax, and then scratch. In addition, when the coil is loosened, it will be tightened from head to head and then scratch. Once the uncoiler tension is too large, the steel plate is spread loose suddenly rolled tight, will also attack scratch. So take steps to reduce brake force when you're done.

Second, because the winding machine is not set properly, resulting in the winding abrasion. After the leather stripping unit stops, it is easy to appear loose in the process of starting again. The loosening of the shear outer ring, the transverse dislocation of the steel coil when unwinding and so on will attack the abrasion. In addition, straightening shear, loose steel coil inserted into the mandrel from the beginning of the coiling will occur when the scratch. The third condition is affected by the hand expansion and contraction of the seizure of the wound. In the leather slabbing machine copper tension lack of lax winding, with the hand expansion and contraction device tension. dislocation of the winding so as to attack the abrasion. In addition, the lateral swing of the steel belt in the looper, overlapping will also attack abrasion.
