Short tranverse crankshaft connecting rod device of warp knitting machine

Abstract

The invention discloses a short-stroke crankshaft connecting rod device for a tricot machine. The invention comprises eccentric shafts, a first shaft journal (4), a second shaft journal (5), a central wall plate (7), a grooved needle bed connected with a first eccentric shaft (1), a yarn guide needle bed crankshaft connecting rod mechanism, a stylet bed crankshaft connecting rod mechanism connected with a second eccentric shaft (2), and a sinker bed crankshaft connecting rod mechanism connected with a third eccentric shaft (3). The first shaft journal (4) and the second shaft journal (5) are respectively and fixedly connected with the end parts of the second eccentric shaft (2) and the third eccentric shaft (3). The second eccentric shaft (2), the first eccentric shaft (1) and the third eccentric shaft (3) are connected with each other in turn and are rotated around the first and second shaft journals (4, 5). The short-stroke crankshaft connecting rod device effectively shortens the motion stroke of weaving elements; the grooved needle travel is between 8 and 12 millimeters; the moving time of yarn guide needles is between 1.5 and 1.8 microseconds; the engine speed is improved to be 2500 to 3000 turns per minute; the noise is less than or equal to 85 decibels; the vibration is small; the energy consumption is low; the device is suitable for high-speed rotation; the power is small; and the productivity is obviously improved.

Description

technical field [0001] The invention relates to a warp knitting machine, in particular to a short stroke crankshaft connecting rod device for a high speed warp knitting machine. Background technique [0002] The warp knitting machine is a knitting machine that uses chemical fiber filaments, such as polyester, nylon, spandex, etc. . Because the warp knitting machine only uses warp threads to weave into cloth, it has the advantages of short production process, high production efficiency, many types of fabrics, low investment costs, and low energy consumption, so it is favored by the textile industry and develops rapidly. Warp knitted fabrics are formed by interlocking loop-forming elements and interlocking loops. The knitting elements are composed of grooved needles, needle cores, sinkers, yarn guide needles, etc. The mutual cooperation between them is realized by the main shaft driving the transmission mechanism and the traverse mechanism. For existing warp knitting machin...

AI Technical Summary

Problems solved by technology

Due to the large vibration of this eccentric link mechanism and the large stroke of the knitting elements, it is difficult to increase the speed of the warp knitting machine to 2500 rpm.
