Problems solved by technology

Since the cooperation between the roller surfaces is purely dependent on the extrusion force between the roller surfaces, the traction effect of the fabric is completely dependent on the integrity and flatness of the roller surfaces. Once the wear occurs between the roller surfaces, the roller structure Traction will be greatly reduced, resulting in a decline in traction quality
In addition, when the two roller surfaces cooperate with each other, a straight line will be formed, and the traction of the fabric by the linear structure will cause the fabric to move up and down, which also affects the traction effect.

Abstract

The invention discloses a pulling mechanism, comprising a first pulling roller and a second pulling roller, the first pulling roller and the second pulling roller are respectively rotatably connected to a support structure, the first pulling roller The rotation direction of the roller and the second pulling roller is opposite, the first pulling roller and the second pulling roller mesh, and the meshing surface of the first pulling roller and the second pulling roller is a concave-convex surface. The invention can improve the traction force, prevent the fabric from moving, and improve the quality and effect of traction.

Description

technical field [0001] The invention relates to a pulling technology, in particular to a pulling mechanism. Background technique [0002] In the prior art, the fabric in the flat knitting machine is usually pulled by a roller mechanism installed in the flat knitting machine. When the current roller structure pulls the fabric, a pair of mutually cooperating roller surfaces squeeze each other, thereby pulling the fabric from one side to the other. Since the cooperation between the roller surfaces is purely dependent on the extrusion force between the roller surfaces, the traction effect of the fabric is completely dependent on the integrity and flatness of the roller surfaces. Once the wear occurs between the roller surfaces, the roller structure Traction will be greatly reduced, resulting in a decline in traction quality. In addition, a straight line will be formed when the two roller surfaces cooperate with each other, and the traction of the fabric by the linear structure...
