Insert-type needle bed for computerized flat knitting machines

Abstract

The invention provides an insert-type needle bed for computerized flat knitting machines. The needle bed is characterized by comprising an insert-type needle bed substrate with a front needle channelmounting groove and a doffing front needle channel combined insert sheet; two side walls of the front needle channel mounting groove of the insert-type needle bed substrate with a front needle channelmounting groove are provided with grooves for reducing the thickness of side walls, wherein the bottom of the groove is arc shaped; two sides of the doffing front needle channel combined insert sheetare provided with arc bosses corresponding to the grooves, wherein the bottom of the arc boss is matched arc shaped. An advantageous effect of the invention is that spacers are provided above the needle slot insert sheet. The width of the needle slot is fixed and evenly divided the width of the needle slot is evenly distributed, which avoids the disadvantage of different size of the needle slot,and avoids the unevenness of the upper interval caused by the slight distortion of the insert sheet. The probability of the sinker and the needle rubbing is reduced, the knock off of weaving needle isavoided; the grip of the needle is effectively controlled; the front groove of the formed needle slot is smaller than the rear groove.

Description

technical field [0001] The invention relates to the technical field of computerized flat knitting machines, in particular to a patch type needle bed applied to computerized flat knitting machines. Background technique [0002] Existing computerized flat knitting machines do not have a front needle track. When the knitting needle goes up to the knitting height or transfer height, the front part of the knitting needle is too much away from the panel. In order to prevent the exposed part from swinging left and right as much as possible In normal knitting, the sinker swinging up and down is used as the "backer", but they will rub against each other. When the sinker is lifted, the knitting needle will lose the "backer". In view of this situation, it is necessary to process single-needle and multi-needle complex patterns or transfer stitches. It is unreasonable to reduce the knitting speed when the fabric is too thin, and it is easy to cause fabric waste and damage the knitting ne...

AI Technical Summary

Problems solved by technology

The gap between the needle groove and the knitting needle has a certain amount of gap depending on the needle type. Because the knitting needle is exposed too much, the "rational damping of the knitting needle movement" is not enough, and the grip of the knitting needle cannot be effectively controlled. The process will also produce such as: at the set density, the knitting density at a speed of 0.8 m / s will be looser than that at a speed of 0.9 m / s. "The damping of the knitting needle movement is not enough" sometimes causes the knitting needle to "climb up" and elongate the loop, resulting in "loose density"

When the exposed part of the knitting needle minimizes the side-to-side swing and affects normal knitting, the yarn pressing piece that swings up and down is used as the "backing", but it will rub against each other. When the sinker is lifted, the knitting needle loses the "backing". When the sheet is working, due to the slight distortion of the needle groove insert, the uneven upper interval will affect its swing deviation, and the probability of friction between the sinker and the knitting needle will be greatly increased, and the needle head of the knitting needle will be knocked off in severe cases.

[0003] In order to seek "rational damping of needle motion" in the needle groove, the computerized flat knitting machine also uses lubricating oil for the needle bed in the actual production process, and the oil with too high "kinematic viscosity" will damage the needle Increased motion damping will cause the knitting needle to "bouncing", and if it is too small, it will not be effective. At the same time, the computerized flat knitting machine is a 24-hour fully automatic equipment. If the wax is too much, the tiny yarn wadding and wax ash will fall into the needle groove during the knitting process and affect the smooth movement of the knitting needle, resulting in "knitting needle movement is not flexible", it is also difficult to transfer and connect loops, and the knitting speed cannot be increased, which is serious. There will also be serious problems of unknown striker needles. The knitting industry often uses "empirical data" to select oil products, but there are also many uncertain factors
