Tension-adjustable extruding and drawing device of drawing frame

Abstract

The invention discloses a tension-adjustable extruding and drawing device of a drawing frame. The tension-adjustable extruding and drawing device of the drawing frame comprises a base, wherein four first fixing plates are symmetrically welded to the top end of the base; limiting grooves are separately formed in the middles of each two first fixing plates; a first connecting rod is embedded in eachlimiting groove, and toothed plates are separately welded to two ends of each first connecting rod; a second connecting rod is welded between the two toothed plates, and one end surfaces of the two toothed plates are connected with gears in an engaged manner; and a crank is welded to one end surface of each gear, and a rotating rod is arranged between the two gears. The gears, the toothed plates,the cranks, the first connecting rod and the second connecting rod are respectively arranged on the two sides of an extruding roller, so that slivers to be extruded on the two sides of the extrudingroller can be adjusted in different tensioning degrees, the tensioning degrees of the slivers to be extruded on the two sides of the extruding roller are conveniently kept moderate, the extruding effect is good, and the drawing efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of drawing frame extruding and drawing devices, in particular to a draw frame extruding and drawing device with adjustable tension. Background technique [0002] The function of the draw frame is to improve the internal structure of the sliver to be extruded, so as to improve the uniformity of its long segments, and at the same time reduce the unevenness of the weight, so that the fibers in the sliver to be extruded are straightened and parallel, and the hooks are reduced, so that the thin The degree conforms to the regulations, so that different types or different qualities of raw materials are mixed evenly to achieve the specified mixing ratio. The extrusion drawing device of the drawing frame is to squeeze and fix the combined sliver to be extruded through the rotating roller; [0003] In the patent "A drawing frame extrusion drawing device" with the application number of 2018219644841, through the design...

AI Technical Summary

Problems solved by technology

[0004] The present invention provides a drawing frame extrusion drawing device with adjustable tension, which can effectively solve the above-mentioned problem in the background technology that the sliver to be extruded on both sides of the extrusion wheel needs to be adjusted in tension, and the extruding The tension on both sides of the pressure roller is different, and the range of adjustment needs to be different.
