Device used for preventing drawn slivers from being accidently stretched and applied to roving frame

Abstract

The invention discloses a device used for preventing drawn slivers from being accidently stretched and applied to a roving frame. The device comprises the roving frame and a sliver guide rack arranged on the roving frame, wherein a plurality of chain wheels and a plurality of sliver guide rollers are arranged on the sliver guide rack, a plurality of sliver cans are arranged below the plurality of sliver guide rollers, and sliver dividers are arranged on the sliver guide rollers; the plurality of chain wheels are connected through a chain, dynamic sensors are arranged on the plurality of chain wheels, dynamic bobbin sensors are arranged on the roving frame, the dynamic sensors and the dynamic bobbin sensors are connected with the input end of a PLC (programmable logic controller) through wires, and the output end of the PLC is connected with a main unit and an alarm lamp. The device has the characteristics of low invested cost, convenience in mounting and wide application range, can be matched with multiple kinds of roving frame devices and can reduce false draft of the sliver guide rollers, so that the friction on cotton slivers is reduced, improvement of finished yarn quality in a follow-up process is facilitated, and finished yarn hairiness is relatively reduced.

Description

technical field [0001] The invention relates to a component of a textile machine, in particular to a device for preventing accidental elongation of a sliver of a roving frame. Background technique [0002] The first thing to do in the textile process is to carry out cotton blending, that is, according to the characteristics of the raw materials and the quality requirements of the yarn, short fibers of different varieties, origins, and batch numbers are mixed in an appropriate way to form a mixed raw material, so that the obtained yarn is superior in appearance quality or internal quality. It can be maintained uniformly for a long time. The mixed raw materials that have been blended are opened, removed, mixed, carded on the carding machine, and loosened into a single fiber state to make fiber sliver. Because the weight of the yarn is required to be uniform, generally 6 or 8 synthetic fiber raw slivers are merged two to three times, and the fibers are straightened and paralle...

Problems solved by technology

The roving is a weak twist product, and the roving spun by the existing roving frame is prone to unexpected elongation after tension, which increases the weight unevenness and evenness unevenness of the roving, greatly affecting the profit of the enterprise
