Lug Air Shaft with Safety Chuck
It is suitable for the retractable shaft of coating, slitting, printing, rewinding, laminating, paper making, bag making, plastic and other related machinery, which can effectively improve work efficiency.
Description
Inflatable shaft is widely used in lithium diaphragm, copper foil, optical film, textile, printing, paper making, packaging and other industries. It can be completed by inflating air into the air nozzle on the air expansion shaft, and supporting the external parts (such as round paper tubes). When unloading is required, the parts on the air nozzle can be easily taken out by pressing them manually. Compared with the traditional mechanical loading and unloading method, the labor intensity is reduced.
