Core Shaft Industry Knowledge And Analysis

With the rapid growth of China's economy, the core shaft machinery industry has become a necessity for people's daily life, as well as people's pursuit of perfection, a large industry that gradually adapts to the needs of economic development.

At present, most of the slitting machines used by Chinese machinery companies are mechanical slip shafts and ordinary air shafts, and the differential air shaft is used less. The mechanical slip shaft consists of three parts: the optical axis and the slip sleeve and the compression spring adjustment mechanism. The working principle is to adjust the torque force of each slip sleeve on the shaft by pressing the pressing force of the spring adjusting mechanism at both ends of the shaft.

Because the structure is that the mechanical pressure is transmitted from both ends of the shaft, the pressure of each slip sleeve is not uniform, so the torque force of each slip sleeve can not be adjusted fully with the change of the tension required for the material change, the slip sleeve The relative sliding is not good, and it is easy to produce irregular winding, broken strips, loose rolls, and unwinding, resulting in material loss. The winding speed is low.

Because the enterprise product grade is not high, the mechanical cutting requirements are not high, the ordinary air expanding shaft and the mechanical slip shaft can reach the basic use requirements, and the production scale of the enterprise is not large, the production pressure is not large, and there is no desire for urgent improvement. Failed to apply. Most manufacturers do not know enough about the difference between the differential shaft and the mechanical slip shaft and the ordinary air shaft. Especially, the cost performance of the slip air shaft and other shafts is not clearly familiar. Higher, coupled with the company's product quality, the pursuit of maximum efficiency without urgent requirements,

The ordinary air expansion shaft consists of two departments: the expansion shaft and the long expansion tube. The size of the damper is adjusted by the inflation pressure. Because the structure of the bulge is a long strip of the through shaft, there is no section, so there is no slip function. When there are multiple strips, there is no corresponding slipping action due to the change of the tension of the material, which easily causes the winding, the broken strip, the loose coil, and the unwinding phenomenon, resulting in material loss. The winding speed is low. Adjusting the air pressure should stop and affect the work efficiency. The unified axis cannot be large or small at the same time. Slitting machine is one of the main independent equipments of mechanical enterprises. The performance and difference of its function directly reflect the level of product quality and production efficiency. The torque of the differential sleeve is adjusted to achieve the required tension of each roll of material on the dividing line, so that the sliding sleeves are relatively slid and the linear velocity is automatically adjusted.

When adjusting the pressure, it must be stopped and adjusted to affect the working efficiency. The sliding air shaft consists of two parts: the air shaft and the slip sleeve. The air expansion shaft adopts the central air pressure control. According to the user model, the online adjustment can be realized without stopping the machine, so that the piston on the shaft is ejected, and each slip sleeve is braked to expand the sliding key, and the paper tube (plastic tube, nylon tube) is fixed. Wait). The function of the reel on the machine determines the function of the slitter is good and bad.

Therefore, the mechanical slip axis is solved, and the problem of broken strips, loose rolls, unwinding, etc. caused by the change of the unevenness of the material thickness during the winding of the common air-expansion shaft is avoided, thereby avoiding the material loss caused thereby. And can collect large and small rolls at the same time on the unified slip air shaft. The winding speed is higher. Because the air pressure can be adjusted without stopping, the machine adaptability and work efficiency are greatly improved. More air shaft reference materials attention
