Numerical control cotton yarn stretching and drawing frame

A technology of drawing frame and cotton yarn, which is applied in the field of sliver that needs to be stretched, combined with wrinkle-resistant and elastic fibers before spinning, can solve the problem of labor-consuming, time-consuming, uneven blending, and stretching and drawing of sliver and elastic fiber. The speed and fineness of the machine are not ideal, and it is not possible to use one machine for multiple purposes.

Problems solved by technology

[0003] Most of the existing spinning enterprises still use old-fashioned mechanical variable speed spinning equipment, which cannot be used for multiple purposes. The speed and fineness of stretching and drawing of yarn and elastic fiber are not ideal, and the jointing is labor-intensive and time-consuming.

Abstract

The numerically controlled cotton yarn drawing frame of the present invention belongs to the field of textile equipment. The digital controller is used to precisely control the rotation speeds of multiple servo motors and work simultaneously. The left servo motor drives the elastic fiber pressing roller, and the right servo motor drives the cotton yarn pressing roller. , the lower servo motor drives the drawing frame drum, the elastic fiber pressing drum lifts the elastic fiber from the turnover drum to the drawing frame drum, and the cotton yarn pressing drum lifts the cotton yarn from the turnover drum to the stretching drawing drum, pulls The stretching and drawing cylinder stretches the two strands of elastic fiber and cotton yarn and merges them into one strand and sends them to the turnover drum below. The speeds of the left and right servo motors are asynchronous, and the speed of the lower servo motor is higher than that of the left and right servo motors. The rotation speed of the motor drives the drawing frame cylinder simultaneously to stretch and combine the elastic fiber and cotton yarn into sliver.

Description

[0001] technology neighborhood [0002] The invention relates to a numerically controlled cotton yarn stretching and drawing frame, which belongs to the field of textile equipment, and in particular relates to fibers that need to be stretched, wrinkle-resistant, and elastic before spinning. Background technique [0003] Most of the existing spinning enterprises still use the old-fashioned mechanical variable speed spinning equipment, which cannot be used for multiple purposes. The speed and fineness of the drawing and drawing of the sliver and elastic fiber are not ideal, and the jointing is labor-intensive and time-consuming. Contents of the invention [0004] The numerically controlled cotton yarn drawing frame of the present invention overcomes the above-mentioned defects, uses a digital controller to precisely control the rotational speeds of multiple servo motors and works simultaneously, the left servo motor drives the elastic fiber pressing roller, and the right servo ...
