Net material automatic winding and coil unloading device

Abstract

The invention discloses a net material automatic winding and coil unloading device. The device comprises a power device, a transmission device, a winding and coil unloading device and a control device, wherein the power device comprises an asynchronous motor, an air cylinder and an air pump, the transmission device comprises a planetary gear train, a central shaft, a sliding rail and a planetary gear support, the winding and coil unloading device comprises winding shafts, rotary clamps, a split-type radial sliding bearing, a pneumatic clamp, a horizontal guide rail, a coil unloading mechanicalarm unit, an air pipe, a rotary joint, an electromagnetic reversing valve and an electric air cylinder, and the control device comprises an electrical cabinet and a position sensor. According to thedevice, the planetary gear train structure is adopted, so that the central shaft and the three winding shafts are driven by one motor, and the production cost and the power loss are reduced; and during coil unloading, the rotary clamps in the winding shafts are loosened under the action of a hydraulic swinging cylinder, so that the tension of coils is reduced, a mechanical arm can directly unloada net material from vacancy of a left support, the purpose of automatic coil unloading is achieved, and the continuous and automatic production process is ensured.

Description

technical field [0001] The invention relates to the field of mechanical structure design, in particular to a net material / film automatic winding and unwinding device. Background technique [0002] At present, there are many rewinding machines on the market, such as rewinding machines for mesh materials in the production workshop. Although these mechanical technologies are relatively mature, their operations often require special personnel to take care of them. When rewinding, technicians are often required to manually To realize the recycling of the net material through operation and guidance, the technician needs to put the reel on the winder, press the end of the net material on the roll, and then the winder drives the roll to rotate for winding. In the process of replacing the material shaft and controlling the rewinding of the mesh material, the machine needs to be shut down or skilled technicians are required to quickly replace the rewinding drum during the work process...

AI Technical Summary

Problems solved by technology

In the process of changing the material shaft and controlling the rewinding of the mesh, it is necessary to shut down the machine or require skilled technicians to quickly replace the reel during the work process. Unnecessary waste of material is also created when rolling

In addition, the existing automatic winding and unwinding mechanism and other invention patents can also realize the corresponding automatic winding and unwinding work, but the structure of the equipment is complex, the control is cumbersome, and additional adjustments are required for products with different thicknesses or even cannot be used

For example, the double-station automatic rewinding and changing device with the patent number CN201810568573.2 can meet the corresponding rewinding and unwinding work, but its structure is complex and cannot be well applied to the high-speed small-roll rewinding work, and there are certain deficiencies
