Classification of Warp Knitting Machines and Methods to Improve Textile Efficiency

Ⅰ. What are the types of warp knitting machines?

Types of warp knitting machines according to the pulling angle: general warp knitting machines can be divided into tricot warp knitting machines (pulling angle of 90°) and raschel warp knitting machines (pulling angle of 170°) according to the pulling angle of grey fabrics).

Types of warp knitting machines according to the number of needle beds: according to the number of needle beds configured, they are divided into single-bed warp knitting machines and double-needle bed warp knitting machines. Single needle bed warp knitting machines are equipped with only one needle bed to produce single jersey fabrics. Double needle bed warp knitting machine is a warp knitting machine with two rows parallel to each other and opposite to each other. On a double-bed warp knitting machine, there are two configurations of the front and rear needle beds, the relative configuration (double rib type) and the alternate configuration (rib type), but most of them are relative configuration. The double needle bed warp knitting machine can knit into loops on each needle bed separately, and then use the partial or full connection to produce fabrics with different styles and different pattern effects from the single needle bed warp knitting machine.

Types of warp knitting machines according to the type of needles: According to the type of knitting needles, warp knitting machines can be divided into compound needle warp knitting machines, latch needle warp knitting machines and crochet warp knitting machines. Early tricot knitting machines used crochet, old raschel knitting machines used latch needles, and modern tricot and raschel knitting machines use compound needles.

Ⅱ. How to improve the efficiency of warp knitting machine textile

1. Transform the counter of the warp knitting machine. When retrofitting, the sensor should preferably be installed in a place that can accurately record the rotation data of the warp beam and is relatively concealed, so as to prevent the sensor from being damaged during replacement of the warp beam or other operations. When installing, considering that it is necessary to meet the requirements of use and save materials, it is believed that warp knitting machines of different structures should choose different installation positions. In the warp knitting machine produced in the early days, because the warp beam is driven by a worm gear, the sensor is installed under the beam head of the warp beam, and an 8 mm bolt is installed on the shaft head as a sensing point, which can achieve every turn of the warp beam.

2. Improve the bar swing mechanism. The yarn laying action is realized by guiding the yarn to the knitting needle through the yarn guide needle. There are generally two forms of relative movement in the yarn laying process. One is the movement of the bar, and the knitting needle is stationary during the yarn laying process. This method is called the active yarn laying of the bar to the knitting needle, and the other is the static bar When not moving, the knitting needle actively moves along the trajectory of the needle hole of the yarn guide.

3. Change the let-off amount and density value of the warp knitting machine. Without changing the distance between the stripping needle groove plates and adjusting the let-off amount and density of the fleece card, grey fabrics of different thicknesses can be obtained. Without changing the distance between the stripping needle groove plates, and adjusting the let-off amount of the face card, the let-off amount of the fleece card and the density value, grey fabrics of different thicknesses can also be obtained.
