Elastic tensile force adjusting device for traction wheels

Abstract

The invention discloses an elastic tensile force adjusting device for traction wheels. The elastic tensile force adjusting device comprises an installation frame, a first connection plate, a first traction wheel, a second connection plate, a second traction wheel, a support screw, a pressure spring and a nut; the first connection plate is arranged at the upper end of the installation frame through a first rotary pin; the first traction wheel is arranged at one end of the first connection plate through a second rotary pin; and a U-shaped groove is arranged at the other end of the first connection plate. The elastic tensile force adjusting device is simple in structure and convenient to operate; the technical problem that the tensile force cannot be continuously adjusted due to the existing tension device can be effectively solved; and large-scale production requirements of wires and cables can be satisfied.

Description

technical field [0001] The invention belongs to the technical field of electric wire and cable production, and in particular relates to an elastic adjustment device for the tension force of a traction sheave. Background technique [0002] In the production process of wire and cable, extrusion molding of insulating layer is a very important process. Copper core wire or semi-finished multi-strand plastic-sheathed copper wire, through the mold of the plastic extruder, forms a plastic insulating layer or the outermost plastic layer on its surface to produce semi-finished or finished wire and cable. Copper core wire or semi-finished multi-strand plastic-sheathed copper wire must be tensioned before passing through the mold of the plastic extruder to ensure the forming quality. The current device and method for tensioning it is to place a heavy object under the tensioning wheel, and use the weight to fall down to tension itself. This tensioning method has the disadvantages that t...

AI Technical Summary

Problems solved by technology

The current device and method for tensioning it is to place a heavy object under the tensioning wheel, and use the weight to fall down to tension itself. This tensioning method has the disadvantages that the tension cannot be adjusted and it is easy to fall. with security risks

[0003] Chinese patents also have some invention patents and utility model patents on improving tensioning methods and devices. These technical solutions have complex structures, are not convenient to use, and have high manufacturing costs. They are difficult to promote and use in actual production.
