Description

Technical Field

[0001] This utility model relates to a needle selector for a computerized flat knitting machine. Background Technology

[0002] The needle selection plate set on the needle plate of the flat knitting machine realizes the needle selection control function. Due to the large number of parts and complex structure of the needle plate, large friction is easily generated between the parts during operation, which reduces wear resistance and fatigue strength, reduces the stability and service life of the parts, not only reducing knitting efficiency, but also increasing machine maintenance costs. Summary of the Invention

[0003] The purpose of this invention is to address the problems existing in the prior art by providing a needle selection plate for computerized flat knitting machines that has high wear resistance and fatigue strength, good stability, and improved service life.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A needle selector for a computerized flat knitting machine has a needle head, a needle bar, and a needle tail directly formed on its body. A front needle heel and a rear needle heel are provided on the upper wall of the needle bar, and a needle selector tooth is provided between the front needle heel and the rear needle heel. A limiting protrusion is provided on the upper wall of the needle head, and a supporting protrusion is provided on the lower wall of the needle tail. An oil storage groove is stamped on the side wall of the needle bar, and the lubricating oil in the oil storage groove constitutes the lubrication structure of the needle selector.

[0005] Preferably, the tip of the needle is rounded.

[0006] Preferably, the support protrusion is an arc-shaped support protrusion.

[0007] Preferably, the oil storage groove is an oil storage groove with an elongated groove.

[0008] Preferably, another option is that the oil storage groove is an oil storage groove provided with multiple circular blind holes and / or square blind holes.

[0009] The beneficial effects of this utility model are that the oil storage groove is stamped on the side wall of the needle bar, which makes the needle selector plate more lubricated during operation, reduces friction, improves the wear resistance and fatigue strength of the product, enhances the stability and service life of the product, increases knitting efficiency, and reduces machine maintenance costs.

[0010] The following embodiments, in conjunction with the accompanying drawings, further illustrate the present invention. Attached Figure Description

[0011] Figure 1 This is a three-dimensional structural schematic diagram of Embodiment 1 of this utility model; Figure 2 yes Figure 1 Schematic diagram of the structure of Example 1; Figure 3This is a three-dimensional structural schematic diagram of Embodiment 2 of this utility model; Figure 4 yes Figure 3 Schematic diagram of the structure of Example 2.

[0012] In the diagram, 1 is the needle tip; 2 is the needle shaft; 3 is the needle tail; 4 is the front needle heel; 5 is the rear needle heel; 6 is the needle tooth; 7 is the limiting protrusion; 8 is the support protrusion; and 9 is the oil reservoir groove. Detailed Implementation

[0013] Reference Figures 1 to 2 This embodiment 1 is a needle selector for a computerized flat knitting machine. The needle selector body is directly formed with a needle head 1, a needle bar 2, and a needle tail 3. The end of the needle head is round. A front needle heel 4 and a rear needle heel 5 are provided on the upper wall of the needle bar. A needle selector tooth 6 is provided between the front needle heel and the rear needle heel. A limiting protrusion 7 is provided on the upper wall of the needle head. A supporting protrusion 8 is provided on the lower wall of the needle tail. The supporting protrusion is an arc-shaped supporting protrusion. An oil storage groove 9 with a long strip groove is stamped on the side wall of the needle bar. The lubricating oil in the oil storage groove constitutes the lubrication structure of the needle selector.

[0014] Reference Figures 3 to 4 The difference between this embodiment 2 and embodiment 1 is that the oil storage groove is an oil storage groove with evenly arranged circular blind holes.

[0015] When this utility model is used, the needle plate of the computer flat knitting machine includes a needle plate, inserts and knitting needle assembly. A needle groove is formed between adjacent inserts. The knitting needle assembly located in the needle groove includes a knitting needle, a long needle plate and a needle selector plate. The needle selector plate is used to push the knitting needle to move along the needle groove.

[0016] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
