Description

Technical Field

[0001] This utility model relates to the field of computerized flat knitting machine technology, and in particular to a computerized flat knitting machine shank. Background Technology

[0002] In the modern textile industry production system, the computerized flat knitting machine, as the core equipment for realizing the automated and efficient knitting of fabrics, directly determines the precision, efficiency, and product diversity of fabric production. As the market demands for the complexity and functional diversity of knitted fabric patterns—such as jacquard fabrics combining warmth and elasticity, and functional fabrics with special textures—higher requirements are placed on the knitting process compatibility and production efficiency of the computerized flat knitting machine. Among these, the shank, as a key component controlling the needle selection action of the computerized flat knitting machine, directly affects the machine's ability to simultaneously execute complex knitting processes, and is a crucial factor restricting the upgrading of the machine's production capacity.

[0003] In the current mainstream computerized flat knitting machine shank technology solutions, the industry generally adopts the classic layout design of "dual needle selectors". That is, only two independent needle selectors are set on the shank, which correspond to some needle selection control needs in the flat knitting process. Since the functional allocation of the two needle selectors is fixed, it is impossible to provide accurate needle selection signal output and motion control for the two independent processes of "knitting" and "hanging stitch". As a result, the flat knitting machine can only adopt an intermittent operation mode in the production process, which is to complete a section of knitting first, then switch to the hanging stitch process, and then return to knitting after completion. This leads to a significant decrease in production efficiency. In view of the above reasons, this application proposes a computerized flat knitting machine shank. Utility Model Content

[0004] The purpose of this utility model is to address the problems existing in the background technology by proposing a computer flat knitting machine shank.

[0005] The technical solution of this utility model is: a computer flat knitting machine shank, including a base plate; the front of the base plate is provided with a hanging triangle, two return triangles and a weaving triangle, and the two return triangles are respectively located on both sides of the hanging triangle; The front of the base plate is provided with three mounting slots and two guards. Each of the three mounting slots is provided with a needle selector. A pointed peak is provided above the knitting triangle. Two density triangles are movably provided on the front of the base plate. Guards are provided on the sides of the two density triangles that are far apart from each other.

[0006] Furthermore, the woven triangle and the pointed mountain are installed together; the hanging triangle is installed in conjunction with the track formed between the woven triangle and the pointed mountain; the hanging triangle is slidably installed on the base plate.

[0007] Furthermore, the positioning triangle and the lifting triangle are installed together.

[0008] Furthermore, the second protective barrier is installed in conjunction with the density triangle.

[0009] Furthermore, the front of the base plate is provided with two inclined grooves, and the back of the base plate is movably provided with two fixing plates, and one side of the fixing plate is provided with a connecting lug.

[0010] Furthermore, two mounting blocks are fixedly provided on the back of the base plate, a guide rod is movably provided on the connecting ear, and a spring is sleeved on the guide rod. One end of the spring is in contact with the mounting block, and the other end of the spring is in contact with the connecting ear.

[0011] Furthermore, both of the aforementioned mountain guards are fixedly connected to the base plate.

[0012] Compared with the prior art, the present invention has the following beneficial technical effects: 1. By incorporating three needle selectors, this design overcomes the limitations of traditional single needle selectors. Leveraging the precise needle selection capabilities of multi-unit collaboration, it enables continuous and uninterrupted selection and control of knitting needles. During operation, with the return cam guiding the needles to their reset position and the cam assisting in needle reversal, the needle selectors accurately distinguish between needles involved in knitting and loop-forming actions. This allows the knitting cam to push the needles through knitting actions such as loop unwinding and loop formation, while the loop-forming cam simultaneously drives the corresponding needles to perform loop-forming knitting. This design not only eliminates the cumbersome process of action switching, significantly improving knitting efficiency, but also flexibly completes complex knitting patterns, meeting the diverse process requirements of different fabrics such as sweaters and scarves, thus broadening the equipment's applicable scenarios.

[0013] 2. This utility model sets up three needle selectors, which, together with the return triangle and the tip, accurately distinguish the knitting needles and complete the knitting and hanging actions simultaneously, saving the switching process and improving efficiency. It can also knit complex patterns and is suitable for sweaters, scarves and other needs. Attached Figure Description
