Introduction to the characteristics of the inflation shaft
1. Wide application: The inflation shaft is an independent design part, from 1 inch to 12 inches, the length and length are determined by the actual needs of the customer. Where there are slitting, printing, rewinding, coating, laminating, bag making The machine, papermaking and other workers for the equipment or other related centers to take up the machine can be applied to the furnace shaft of the factory.
2, cost-effective: the design of the inflatable shaft is designed for practical work, and can be applied to various types of coils such as thick and wide.
3, long use time, simple maintenance: Although the inflatable shaft is a mechanical accessory, but each part of its own structure has a fixed specification, can be used interchangeably, making it easy to maintain. Our factory has strict requirements on the quality of the various components of the air-expansion shaft, and the product quality is absolutely guaranteed.
4. Single fitting: The inflatable shaft is a single spare part of the winding unwinding machine. Each part in the structure has a fixed size and can be disassembled and combined to make maintenance easy and durable.

The air expansion shaft, also known as the gas rise shaft, is widely used and can be applied to any machine that has winding, unwinding and slitting. The inflation shaft is an important part of the printing equipment and has important applications in paper slitting machines.
The inflation shaft is a special type of winding and unwinding. After the high pressure is inflated, the surface can be raised. The shaft is quickly retracted after deflation. It has independent slip and torque setting structure. A roll of material due to the thickness and uneven tension caused by the phenomenon of unwinding, effectively improve product quality and work efficiency.
Question 1: The slitting machine is not winding up
Most of this is because the paper core is not suitable, as long as the paper core that meets the required inner diameter is replaced, and the winding roller is used in the winding process, the slitting machine can also be prevented from being wound up.
Question 2: The trend of slitting and winding materials
This is mainly because the winding tension is not correct, and the appropriate winding tension of the paper slitting machine is adjusted. The winding roller is used for winding and the cutting material is wrapped by the pressing roller before entering the winding paper core.
Question 3: The meter count is not allowed
This kind of problem can be used to contact the feeding roller at the same time with the two wheels of the meter wheel, and make a mark on the meter wheel to hand 5 turns to count 1 meter or replace the meter.
It can be seen that the inflation shaft is widely used in printing equipment, and is an important component of the paper slitting machine. It can be used for slitting equipment with high quality requirements and relatively fast speed.
