Description
Technical Field
The invention relates to the technical field of glove machine accessory structures, in particular to a triangle device for bidirectional knitting of gloves.
Background
The participation of the guide pin cam device in the conventional glove knitting machine on the market in knitting is divided into three types: 1. knitting from the rubber triangle; 2. knitting from a needle lifting cam; 3. the reverse direction is used for sealing and braiding, the structure is basically only two, and the first is that: only has the function of forward needle lifting, and the reverse needle lifting is only used for sealing. In the forward needle lifting process, the moving track of the needle stitch is as follows: firstly, rising along the inclined plane of the rubber band needle raising triangle until reaching the highest point, then descending along the inclined plane of the rubber band density triangle until reaching the bottom of the rubber band needle raising triangle, then rising along the inclined plane of the forward needle raising triangle until reaching the highest point, then descending along the triangle track, continuing descending along the inclined plane of the forward density triangle until reaching the bottom of the rubber band needle raising triangle after descending to the position of the forward density triangle, and finally finishing one-way knitting of knitting the rubber band and then knitting the yarn.
Second kind: meanwhile, the knitting glove machine has the functions of forward needle lifting and reverse needle lifting, and is called a jacquard glove machine or a computerized flat knitting machine in the industry. If the reverse lifting is performed after the forward lifting in the same knitting course, the moving track of the needle stitch is: after passing through the bottom of the elastic density triangle, the motion is performed through the bottom of the reverse density triangle. Although the reverse needle lifting can be realized in the working mode, the descending amplitude of the knitting needle for feeding the elastic threads is increased, and then the elastic threads are broken or the size and the tightness of the rib parts of the glove are uncontrollable.
Therefore, the knitting glove machine in industry generally does not implement the reverse needle lifting working mode when knitting rib parts, and even if the reverse needle lifting is needed, the following modes are adopted:
1. knitting of the elastic thread is not performed in the same knitting course in which the reverse lift is performed (industry term is called tuck);
2. if the knitting of the elastic thread is required to be considered in the reverse knitting process, in order to prevent the elastic thread from breaking or affecting the knitting quality of the rib part, the reverse density cam can only be greatly adjusted to ensure that the bottom of the reverse density cam and the bottom of the elastic thread cam reach the same height, so that the descending amplitude of the knitting needle with the elastic thread can not be changed by the reverse density cam. However, this causes a high knitting density of the yarn in the course, and normal knitting cannot be achieved.
In summary, in the conventional glove knitting machine or flat knitting machine, the reverse stitch knitting and the knitting of the elastic cord are not performed in the same knitting course of the knitted rib portion, so that the conventional glove knitting machine or flat knitting machine cannot be well applied to the processing mode of the bidirectional synchronous knitting. Aiming at the problem, the Chinese patent application number 202210746452.9 discloses a guide pin triangle device suitable for bidirectional knitting of a glove rib part, which comprises a mounting plate and a guide pin assembly arranged on the mounting plate, wherein the guide pin assembly comprises an elastic guide pin structure, a yarn guide pin structure and the like, and when the rib part of the glove is knitted by a knitting glove machine, the guide pin triangle device is improved, so that the forward needle lifting and the reverse needle lifting can be realized at the same time, and the productivity of the knitting glove machine is greatly improved.

Control of density:
1. the general control method comprises the following steps: the size of the device is controlled by a cam on the machine head, and the size of the device can be controlled;
2. how to control when encrypting at the current density: controlled by a ram (not shown), which can only be encrypted.
When knitting to the left: the left density pushing feet 53 are driven by the ejector rod, and the left sliding seat 41 can be pushed to move upwards by anticlockwise rotation, so that the stroke is shortened, the looping is reduced, and encryption is realized; meanwhile, the left-hand density pushing feet 53 are driven by the connecting plate 42 and the rotating plate 43 to enable the rotating plate 43 to rotate clockwise, so that the needle pressing triangle 10 moves downwards in the needle pressing sliding groove 11.
When knitting to the right: the right density pushing feet 54 are driven by the ejector rod to rotate clockwise to push the right sliding seat 31 to move upwards, so that the stroke is shortened, and encryption is realized.
Controlling the knitting density of the elastic triangle:
the knitting density of the rubber band can be controlled by the right density triangle 4 moving up and down along the groove, and the right density pushing foot 54 is controlled by the ejector rod.
The above embodiments are illustrative of the present invention, and not limiting, and any simple modifications of the present invention fall within the scope of the present invention.
