Description
Technical Field
The application relates to the field of textile equipment, in particular to a top plate jacquard mechanism of a circular knitting machine, a jacquard knitting mechanism and a circular knitting machine.
Background
A circular knitting machine is generally referred to as a double-sided circular knitting machine, which is a knitting machine capable of simultaneously knitting the inner and outer surfaces of a knitted fabric. The core mechanism of the circular knitting machine is a knitting mechanism arranged at the central part of a frame, and the core of the knitting mechanism consists of a needle bed which is driven by a motor to continuously rotate around the axis of the center of the needle bed and a group of water caltrops fixed on the frame, and the knitting principle and the process of the circular knitting machine of the prior type are as follows: the upper surface and the side surface of the needle bed are provided with a plurality of strip-shaped 'crack' structures, the technical staff usually refers to a needle groove, each needle groove is internally provided with a group of jacquard mechanisms, the existing jacquard mechanisms are usually composed of knitting needles and jacquard pieces for controlling the knitting needles to perform various knitting actions, the jacquard mechanisms are always clamped in the needle grooves, in addition, water caltrops are usually fixed at positions above the surfaces of the needle grooves correspondingly, the surfaces of the water caltrops are delineated with a plurality of sinuous 'groove' structures, the technical staff usually refers to a needle track, the knitting needles or the jacquard pieces are correspondingly provided with a structure of 'protruding blocks' protruding outwards, the technical staff usually refers to 'heels' on the knitting needles, the 'heels' on the jacquard pieces are usually referred to as 'heels' on the needle tracks, the jacquard mechanisms are forced to move along the extending direction of the needle tracks under the driving of the rotating drive of the needle bed after the needle tracks are all the time, the water caltrops are in a sliding slide way, the sliding heels on the needle tracks are more than the sliding grooves, the sliding heels are not broken, the sliding heels are broken down like the needle tracks, the sliding grooves are broken, the needle grooves are broken, the knitting of the knitting fabrics are not broken, the knitting fabrics are finished by the synchronous motion of the needle grooves, and the knitting of the knitting fabrics are not broken, and the knitting of the knitting fabrics are similar to the needle grooves are broken.
Such double-sided needle beds capable of knitting are generally divided into an upper tray, which is generally an annular dial, corresponding to one surface of the knitted fabric, and a lower tray, which is generally a cylindrical cylinder, corresponding to the other surface of the knitted fabric. The upper disc of the needle bed is circular, so that the needle grooves are arranged along the radial direction of the needle disc, the jacquard piece is arranged on one side close to the inner ring of the needle disc, and the knitting needle is arranged on one side close to the outer ring of the needle disc.
As disclosed in the patent of the jacquard mechanism of the circular knitting machine (hereinafter referred to as the reference document) with the chinese patent No. 201410326934.4, the existing jacquard mechanism is generally composed of knitting needles and control pieces, and the raising butt on the jacquard piece controls the jacquard piece to move to the outer ring side of the dial to eject the knitting needles to complete the needle-out action, and the pressing butt on the knitting needles generally controls the knitting needles to move to the inner ring side of the dial to press the jacquard piece back to the original position during needle retraction. In addition, since all jacquard sheets and knitting needles are required to be ejected, the row needle rail corresponding to the butt is always provided at the position closest to the inner ring of the dial.
In addition, the knitting action which can be arranged in the unit area is closely related to the length of the needle track because the knitting needles and the jacquard pieces are controlled by the needle track, however, the water chestnut matched with the upper disc is fan-shaped because of the special shape limitation of the needle disc, so that the stroke of the needle track in the water chestnut in the same unit area is shorter at the position of the needle track which is closer to the lower bottom of the needle track, and the knitting action which can be arranged is correspondingly reduced; as shown in FIG. 1, in the comparison pattern diagram of the arrangement of the needle tracks on the water chestnut in the unit area, each triangle with bending and waving in the dotted line part corresponds to one arrangement action, and it can be seen that when the same action is arranged, the number of the weaving actions on the track a is obviously less than that on the track b because the track a is closer to the inner ring than the track b.
Moreover, it has been said above that according to the basic principle of knitting, the existing needle lifting tracks are all arranged at the position closest to the inner ring, so that knitting actions which can be arranged on the needle lifting tracks are the least, and according to the 'barrel effect', we can know that the number of knitting actions on the needle lifting tracks restricts the number of knitting actions of the existing upper disc jacquard mechanism. The number of knitting actions is closely related to parameters such as knitting efficiency per unit time, complexity of knitting patterns, knitting density and the like of the knitting machine, so that the improvement and development of the performance of the whole knitting machine are limited by the unreasonable structure of the existing upper disc jacquard mechanism.
