Hydraulic Air Expansion Safety Core Chuck for Corrugating Paper Mill Roll

Product Description

Expansion Type Mechanical Chuck

Expanding mechanical grippers lock paper cores securely in place by means of a unique clamping method. In contrast to traditional air-expanding shaft or keyed holders, expanding holders use mechanical principles to achieve efficient core clamping through clever design of the internal structure. This not only avoids the problem of paper wastage that may occur in the traditional way, but also improves production efficiency.

On the corrugated paper production line, the expanding mechanical chuck is able to clamp the paper core tightly and stably, ensuring that the rolled paper does not shift or loosen. While traditional air-expanding shafts may have problems such as unstable air pressure and air leakage, the expanding chuck performs the clamping task more reliably by mechanical means.
 

Main Feature

1. Shaft-less design structure improves the speed of winding and unwinding;
2. Wide sliding plate supports the inner hole of the core, large contact area, smooth rotation.
3. It is not easy to produce slippage and damage the core bore;
4. The surface of the sliding plate is equipped with concave and convex lines to increase the locking force;
5. Taper surface top tightening, no empty stroke, smooth starting and stopping tensioning force;
6. Built-in spring, automatic reset when loosened;
7. Integral forging alloy steel spindle, wide load range.
