With the continuous improvement of technology and economic development, the air shaft is widely used in enterprise equipment as a special type of winding and reeling. However, as the mechanical function increases, the power used will increase. Large, in order to be able to reduce the power of its use without changing the performance, to achieve energy-saving effect, the specific method is:
The ordinary air expansion shaft consists of two departments: the air 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 slippery action due to the change of the tension of the material, which easily causes the coil to be unwound, broken, loose, and unwound, 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 function of the reel on the machine determines the function of the slitter is good and bad. At present, most of the slitting machines used by China's machinery enterprises are mechanical slip shafts and ordinary air shafts, and the slip 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. 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 middle 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 torque force of each slip sleeve is adjusted according to the inflation pressure to achieve the adjustment of the required tension of each roll of material on the dividing line, so that the sliding sleeves are relatively slid and the linear speed is automatically adjusted.
When the air-expansion shaft is used for energy-saving, because the material thickness is different during production, the tension of the equipment is insufficient, thereby increasing the power consumption of the equipment. In order to achieve the energy-saving effect, it is necessary to change the equipment accordingly. Air pressure adjustment can also be performed if necessary, thereby effectively reducing material waste and improving equipment use efficiency.
