An air splicing device

Abstract

The invention discloses an air splicing device. The air splicing device comprises a base, wherein the middle part of the base is provided with a splicing cavity, the two sides of the base are provided with untwisting cavities, and the rear side of the base is provided with a cylinder; a sliding bar sleeves a piston rod of the cylinder, yarn guide boards are arranged at the two sides of the splicing cavity, and the top part of the splicing cavity is provided with a splicing cover; the two side walls of the base are provided with fixing plates, a clamping mechanism and a shearing mechanism are sequentially hinged to the outside part of each fixing plate from back to front, and a yarn shifting lever is hinged to the inside part of each fixing plate; a pressing lever extends along the rear side to form a hooked component, two adjusting levers are connected with pulley through holes, and the pressing lever and movable shears are provided with transmission teeth; the two ends of the pulley are respectively sleeved by a connecting rod, and another end of each connecting rod is connected with a threading mechanism. The air splicing device provided by the invention is simple in structure; furthermore, the clamping, shearing and threading can be coherently completed by additionally installing a drive mechanism into clamping, shearing and the threading mechanisms, therefore the splicing quality and the splicing efficiency can be improved.

Description

technical field [0001] The invention relates to an air splicing device, which specifically includes clamping, shearing, yarn drawing and splicing mechanisms, and belongs to the technical field of textile machinery. Background technique [0002] The air splicing device is a yarn splicing device commonly used on winding machines in the textile industry at present, and represents the advanced technology of jointless yarn connection. Its working principle is to use air power and mechanical components to work together to untwist the two yarn ends first, and then splice them. That is, the upper and lower yarn ends are first introduced into the splicer and clamped, and the excess yarn ends are cut off; the two yarn ends are untwisted by high-pressure airflow, so that the yarn ends are loose in the shape of a brush, and then the splicing chamber is used to The high-pressure swirling air in the machine joins the two yarns. This splicing method is called knot-free yarn because it do...

AI Technical Summary

Problems solved by technology

At present, there are mainly two types of yarn delivery mechanisms for adjusting the yarn splicing length: electric and mechanical mechanisms: the electric method uses a computer-controlled stepping motor to adjust the yarn splicing length, but the attached electric system is complicated and expensive ;The mechanical mechanism is to use a wrench to move the length adjustment lever, pull out the yarn end entering the untwisting tube to an appropriate length, and then press the yarn with the yarn pressing lever, depending on the type and count of the yarn , the adjustment range can be set to multiple gears, the efficiency is low
