Four-bar tricot terry warp knitting machine capable of producing terry fabric

Abstract

The invention relates to a four-bar tricot terry warp knitting machine capable of producing a terry fabric. The four-bar tricot terry warp knitting machine comprises a crankshaft, the shaft necks of the crankshaft are installed on a connecting rod rest, and the connecting rod rest is installed in a rack oil tank of the warp knitting machine; the crankshaft is provided with eccentric parts which are composed of the first eccentric part and / or the second eccentric part and the third eccentric part, the first eccentric part is connected with a slot needle guide bar swinging device, the second eccentric part is connected with a needle core swinging device, and the third eccentric part is connected with a sedimentation patch swinging device. According to the four-bar tricot terry warp knitting machine capable of producing the terry fabric, the component number of a main transmission mechanism of the machine is decreased, and the space is more compact; organization and production are easy, maintenance is convenient, and the production efficiency is significantly improved; the warp knitting machine is steady and reliable in operation, low in noise and little in energy consumption.

Description

technical field [0001] The invention relates to the technical field of knitting, in particular to a four-bar tricot terry warp knitting machine capable of producing terry fabrics. Background technique [0002] The transmission device of the main shaft of the traditional pile warp knitting machine uses a conjugate cam or an eccentric linkage to control the movement of the loop forming parts. Conjugate cam mechanism has complicated structure and design, requires high manufacturing and assembly precision, and is difficult to control. The noise is large during operation, and the cam is easy to wear during use. After wear, it will have a serious impact on the knitting motion accuracy of the machine, so that the yarn cannot be looped normally during weaving. The eccentric link mechanism is a kind of planar link mechanism. Its advantage is that the pressure per unit area of ​​the motion pair is small, and the surface contact is easy to lubricate, so the wear is reduced; the proces...

AI Technical Summary

Problems solved by technology

The disadvantage is that when the movement is more complex, more components are required, and the design and balance problems are more complicated; there are gaps in the contact surfaces of each kinematic pair, and the more components, the greater the cumulative error of the mechanism

Therefore, the production efficiency of the existing loop warp knitting machine is not high, and the equipment maintenance is inconvenient
