Jinan Jinchangtai Industry And Trade Co., Ltd
Applicable to the rewinding or slitting of packaging materials such as web, plastic sheet, aluminum foil, PVC, plastic film, insulating material and so on.
It is an ideal equipment for fine cutting materials.Frame fixed good, small gap, high precision, to ensure the slitting machine can operate in high-speed.
Clamping reliable, low malfunction rate, the unique design makes it easy to dismount, and can replace the friction keys conveniently with no affection to the rotation accuracy.
Friction key materials are patented formula, good consistency of dynamic and static friction coefficient, less affected by temperature ,high wear resistance and long service life.
Adopting high quality 40 chrome as the shaft ,which greatly improve the bearing capacity of the whole shaft.
The overall quenching and tempering treatment improve the wear resistance and corrosion resistance,which make it possible to use in a variety of environment.All bearing are imported from Japan,which help extend the overall life.
Steel ball won't drop and the shaft will not bent,even been used 2years.
We have the quality control system during the whole production from the very beginning to the end and our principle is to make sure each roller is qualified.
The differential air shaft consists of a plurality of slip rings, which can overcome the problem of unwinding and material damage. The slippage rings are controlled to slip at a certain slip torque (torque), and the amount of slip exactly compensate for the difference in speed, thus it can control the tension of each roll precisely, which ensure the winding quality.
The use of differential air shaft improves the speed of the slitter, the accuracy of the winding and the degree of automation.At the same time,it shortens the preparation time and achieve the humanized operation. In particular for polyester thin materials which have poor tensile resistance and big difference in thickness.The use of differential air shaft can reduce the difficulty of winding.Besides, using differential air shaft to wind or unwind precious materials, metal foil and special paper roll, can greatly improve the production yield, reducing the cost of production.
