Description

Ultra-dense needle plate structure of computerized flat knitting machine

Technical Field

The utility model relates to the technical field of computerized flat knitting machines, in particular to an ultra-dense needle plate structure of a computerized flat knitting machine.

Background

The computerized flat knitting machine is known as a double-needle-plate latch needle weft knitting machine, and the knitting working process is as follows: the knitting needle arranged in the needle groove on the needle plate is driven to move up and down along the needle groove by the machine head and a triangular mechanism, namely a triangular system, arranged on a triangular bottom plate of the machine head in the reciprocating motion process of the machine head along a guide rail (also called a machine head guide rail) of a machine frame, and the knitting of the fabric is finished under the matching of the triangular mechanism and a drawing and cloth rolling mechanism.

The cam mechanism is similar to a group of plane cams, the stitch of the knitting needle can enter the cam, namely the groove of the cam, the cam is moved, the knitting needle is forced to do regular lifting motion (extend out of or retract into the needle groove) in the needle groove of the needle plate, and the yarn is knitted into the fabric through the actions of the needle hook and the needle latch. In the process of ascending (extending out of the needle groove) of the knitting needle, the coil gradually withdraws from the needle hook, opens the latch and withdraws from the latch to be hung on the needle rod; during the descending (retracting) process of the knitting needle, the needle hook catches the newly laid yarn and draws and bends the newly laid yarn into a loop, meanwhile, the original loop hung on the needle rod is separated from the needle hook, and the new loop passes through the old loop and is connected with the old loop in series. Thus, the loop strings knitted by the plurality of knitting needles are connected to each other to form the knitted fabric.

It is obvious that the needle plate with the knitting needles is a key component in a knitting mechanism system, and the distance (needle pitch) between adjacent knitting needles arranged along the length direction (transverse direction) of the needle plate generally directly influences the knitting density of the fabric, in other words, the larger the needle pitch is, the longer the arc line between the loops is, so that the tightness of the knitted fabric is poor, namely, the fabric is sparse; on the contrary, the smaller the needle pitch, the denser the woven fabric texture.

Of course, in general knitted fabrics, the denser the fabric is, the better the fabric is. For this reason, some manufacturers have started to improve the knitting mechanism, as shown in fig. 1 and 2, by increasing the number of insert grooves 101 per inch along the length direction (transverse direction) of the needle board 100 to reduce the distance between two adjacent inserts, thereby achieving the purpose of reducing the needle pitch, however, this method is limited by practical production processes, and cannot infinitely reduce the needle pitch, and the maximum limit can only be set with 16 knitting needles per inch of the needle board length, because the size of the needle pitch is determined by the distance between two adjacent insert grooves 101, and the approach of the adjacent insert grooves 101 will inevitably cause the partition board 102 between two adjacent insert grooves 101 to be thinned, and when the partition board 102 is thin to a certain extent, the partition board 102 will deform during the process of milling the insert grooves 101, and even "milling and striking" phenomenon will occur. In addition, a method can shorten the needle pitch, namely, two symmetrical extra needle grooves are milled on two side walls of the inserting sheet, and only one knitting needle can be placed in one original needle groove, so that two knitting needles can be installed to increase the number of knitting needles per inch, so as to achieve the purpose of shortening the needle pitch. Therefore, how to shorten the needle pitch as much as possible, increase the number of knitting needles per inch and improve the tightness of the knitted fabric becomes a technical problem which needs to be solved urgently.
