Drawing frame coiling chassis

Abstract

The invention provides a drawing frame coiling chassis, and relates to the field of auxiliary devices of textile machinery. The drawing frame coiling chassis comprises an outer cylinder and a lifting device, wherein inner step holes are formed in one end of a top face of the outer cylinder, the step hole in one segment close to the top face is smaller than the step hole in one segment away from the top face and protrudes inward, the thickness of the protrusion part is smaller than the lengths of connecting parts between a sliver can roller and a cylinder body, the diameter of an inner circle formed by the protrusion part is 1mm larger than that of an external common tangent circle formed by three connecting parts between the sliver can roller and the cylinder body along the radial direction, through holes uniformly distributed along the circumference are formed in the protrusion part, and blind holes uniformly distributed along the circumference are formed in the protrusion part; the bottom of the lifting device is connected with the inner step holes of the outer cylinder and is connected with a spring. The drawing frame coiling chassis provided by the invention can be used for effectively preventing the slipping phenomenon of the roller on the chassis, and meanwhile when the sliver can roller is dismounted, the operation is simple, so that the labor intensity is greatly reduced.

Description

technical field [0001] The invention relates to an auxiliary device of a textile machine, in particular to a coil chassis of a drawing frame. Background technique [0002] Drawing frame is an important process in spinning engineering. With the strong demand of the market, the improvement of drawing frame was greatly stimulated, and the drafting type of drawing frame was reformed, from increasing drafting to Double-zone drafting, and then changing from straight-line drafting to curved-line drafting, significantly improved the quality of the sliver and realized shrinkage. The spinning quality has been significantly improved since then, and the spinning industry has also developed rapidly. Therefore, the process of drawing is also an important criterion for testing whether the spinning industry is advanced or not. [0003] At present, during the operation of the existing drawing frame, the sliver drum is placed on the coiling chassis and rotates with the chassis, and the slive...

AI Technical Summary

Problems solved by technology

[0003] At present, during the operation of the existing drawing frame, the sliver drum is placed on the coiling chassis and rotates with the chassis, and the sliver coming out of the coiling coil bends into the sliver barrel in a cycloidal form. When the sliver in the sliver barrel reaches a certain length, the sliver will squeeze the lower surface of the sliver plate, and the friction will become larger, so that the sliver barrel placed on the sliver chassis cannot be synchronized with the sliver chassis Rotation will seriously affect production efficiency and product quality

[0004] In the prior art, in order to solve the phenomenon that the sliver drum slips on the ground, it is usually adopted to design a slot on the surface of the sliver chassis to increase the friction, and the slot is positioned to be disassembled when the sliver drum is fully loaded. Extremely inconvenient and increases the labor intensity of workers
