Broken thread connecting device for cotton thread twister

Abstract

The invention relates to the field of processing equipment of cotton industry, particularly to a broken thread connecting device for a cotton thread twister. The support piece of a thread guiding unit is fixedly provided with a first press block, the top of the first press block is provided with a photo-resistor, and the first press block is fixedly provided with an abutting block above a frame; a second press block is arranged between the first press block and the thread guiding unit and connected to the bottom of first press block through a tension spring; the thread guiding unit is provided with a groove; the bottom of the second press block is fixedly provided with a rubber block which can press spun yarns; the outer circumference of the thread guiding unit is provided with cavities for containing instant adhesives; the inside of the second press block is provided with a pressing hole, an concave inserting rod which can be inserted into the cavities is matched inside the pressing hole, both ends of the inserting rod are matched in pair with the cavities, and the inserting rod is fixedly provided with a connecting rod; a controller is used for controlling a telescopic cylinder to start according to signals of the photo-resistor. The broken thread connecting device for the cotton thread twister can bond broken yarns without waiting for workers to repair, and meanwhile, save downtime restoration and avoid affecting the production schedule.

Description

technical field [0001] The invention relates to the field of processing equipment used in the cotton textile industry, in particular to a thread connecting and breaking device of a twisting machine for spinning cotton threads. Background technique [0002] The twisting machine refers to the production equipment that twists multiple strands of spun yarn into one strand in the cotton spinning industry. The twisting machine processes the yarn or the yarn products after synthetic strands into linear products for weaving and knitting. The process of cotton spinning includes processes such as opening and cleaning, carding, sliver coiling, combing, drawing, roving, spun yarn, winding and twisting. The twisting machine is used in the twisting process. The spun yarn passing through the twisting machine It is the finished product of the strand. [0003] Since multiple strands of spun yarn are twisted into one strand during twisting, the part of the spun yarn in contact with the mecha...
