An automatic control device for mesh tension in a weaving machine

Abstract

The invention provides a net piece tension automatic control device for a net weaving machine. The net piece tension automatic control device is provided with a swinging arm, an active net winding roller group, a passive net winding roller group and a net collecting roller group, wherein a bearing assembly is arranged at the lower part of the swinging arm, a main shaft is arranged beside the swinging arm, a net winding cam seat is arranged on the main shaft, the active net winding roller group is provided with a main net winding roller and a main net winding overrun clutch, the passive net winding roller group comprises a passive net winding roller and a first press roller, a passive net winding overrun clutch is fixedly arranged on the passive net winding roller, a net passing roller is arranged above a tension roller, and the net piece tension automatic control device is arranged in the net weaving machine. The structure is reasonable, the operation is more stable and more reliable in the work process, net pieces output from the middle of a shuttle hook total process can be output to the passive net winding roller group through the net winding roller group, and the identical stability of the tension can be maintained in the conveyance process.

Description

technical field [0001] The invention relates to a mesh control device, in particular to an automatic control device for mesh tension in a net weaving machine. Background technique [0002] The net winding and net tension control device of the existing net weaving machine includes: a main web winding roller group mechanism, a passive web winding roller group mechanism, and an electric net retracting mechanism. In the prior art, the mesh output by the main anilox roll group relies on the sprocket mechanism to achieve the linkage between the main anilox roll set and the passive anilox roll, so that the passive anilox roll group outputs the mesh, and the main anilox roller shaft is loaded There are large sprockets, and the small sprocket is determined by the thickness of the wire and the size of the mesh. The thicker the wire, the bigger the mesh. On the contrary, the larger the mesh is, the opposite is true. The mesh output by the roller is directly driven by the tension rolle...

AI Technical Summary

Problems solved by technology

This mechanism has the following disadvantages: practice according to the thickness of the wire and the size of the mesh, the determination coefficient, the sprocket on the passive winding roller, the operation is very inconvenient, the mesh is easy to be uneven, and the amount of waste mesh is large. The tube keeps winding, the diameter is getting bigger and bigger, and the tension of the mesh is getting bigger and bigger. It is very easy to have uneven mesh, and the knots of the mesh are not neat. From the net to the net, the tension of the mesh is difficult to control. Low authenticity rate
