Abstract
Description
Technical Field
[0001] This utility model relates to the field of flat knitting machines, and in particular to a pressure needle selector plate for flat knitting machines. Background Technology
[0002] In the knitting process of a flat knitting machine, the control of the needle selector and spring-loaded needle feet has a crucial impact on the accuracy and efficiency of the knitting. Traditional flat knitting machines often have a complex structure, with needle selectors and spring-loaded needle feet on the needle plate to achieve needle selection and needle foot control functions respectively. This not only makes the needle plate structure complex, but also easily generates greater friction between components during the operation of the needle assembly, reducing knitting efficiency, increasing energy consumption and machine wear, and also increasing maintenance costs and difficulty. Utility Model Content
[0003] This invention addresses the shortcomings of existing technologies by providing a pressure needle selector for a flat knitting machine.
[0004] To solve the above-mentioned technical problems, the present invention provides a solution through the following technical method:
[0005] A needle selector plate for a flat knitting machine includes a needle selector plate body, which sequentially comprises an integrally formed needle head, needle shank, and needle tail. The needle shank is provided with a needle selector boss, which is divided into eight needle selector sections according to the position of the needle selector boss. A limiting groove that cooperates with a limiting wire is provided at the connection between the needle head and the needle shank. A clearance groove is provided at the connection between the needle shank and the needle tail. The clearance groove cooperates with the needle plate wire and rotates at a certain angle with the needle plate wire as the center. This allows the needle selector plate body to rotate under pressure and drive the first needle heel on it to sink into the needle plate, thereby combining the needle selector plate with the spring needle foot. The needle selector plate structure of this application has the functions of both a needle selector plate and a spring needle foot, effectively solving the problems of complex needle plate structure, high friction, and low knitting efficiency of existing flat knitting machines.
[0006] Preferably, there are three limiting grooves, which are distributed laterally along the extension direction of the needle plate body on the upper surface of the needle plate body. The three limiting grooves correspond to three different working positions.
[0007] Preferably, a limiting protrusion is also included, which is located at the tail of the limiting groove. The protrusion height of the limiting protrusion is greater than the height of the limiting wire that fits on the limiting groove, and the limiting protrusion prevents the limiting wire from slipping off.
[0008] Preferably, the clearance groove is located on the lower surface of the connection between the needle bar and the needle tail.
[0009] Preferably, the upper surface of the needle tip is provided with an upwardly protruding first needle heel.
[0010] Preferably, the upper surface of the tail of the needle bar is provided with a second needle heel that protrudes upward.
[0011] Preferably, the end where the needle tail connects to the needle bar is provided with a bending notch, the bending notch is located on the side of the needle tail, and the depth of the bending notch is 40% to 60% of the thickness of the needle plate body.
[0012] Preferably, the needle tail is bent, and the angle between the axis of the needle tail and the axis of the needle bar is 2° to 4°. A certain bending angle is formed between the needle tail 13 and the needle bar 12, and a certain elasticity is reserved. The elasticity is used to make the needle selection plate body snap into the needle groove.
[0013] This utility model, by adopting the above technical solutions, has significant technical effects: the needle selection plate of this utility model, through innovative structural design, effectively solves the problems of complex needle plate structure, high friction, and low knitting efficiency in existing flat knitting machines. It has great practical value and market promotion prospects, and provides strong support for the development of flat knitting machine technology. Attached Figure Description

Detailed Implementation
[0019] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.
[0020] Example 1
[0021] A needle selector plate for a flat knitting machine, as shown in the figure, includes a needle selector plate body, which sequentially includes an integrally formed needle head 11, a needle shank 12, and a needle tail 13. The needle shank 11 is provided with a needle selector boss 2, which is divided into the first to the eighth needle selector sections according to the position of the needle selector boss 2. The connection between the needle head 11 and the needle shank 12 is provided with a limiting groove 3 that cooperates with a limiting wire. The connection between the needle shank 12 and the needle tail 13 is provided with a clearance groove 4. The clearance groove 3 cooperates with the needle plate wire and rotates at a certain angle with the needle plate wire as the center. This allows the needle selector plate body to rotate after being pressed, and drives the first needle heel 5 on it to sink into the needle plate, thereby combining the needle selector plate with the spring needle foot. The needle selector plate structure of this application has the functions of both a needle selector plate and a spring needle foot, effectively solving the problems of complex needle plate structure, high friction, and low knitting efficiency of existing flat knitting machines.
[0022] Example 2
[0023] Similar to Embodiment 1, except that there are three limiting grooves 3. The three limiting grooves 3 are distributed laterally along the extension direction of the needle plate body on the upper surface of the needle plate body. The three limiting grooves 3 correspond to three different working positions.
[0024] It also includes a limiting protrusion 31, which is located at the tail of the limiting groove 3. The protrusion height of the limiting protrusion 31 is greater than the height of the limiting wire that fits on the limiting groove 3. The limiting protrusion 31 prevents the limiting wire from slipping.
[0025] The clearance groove 4 is located on the lower surface of the connection between the needle bar 12 and the needle tail 13.
[0026] Example 3
[0027] Similar to Embodiment 1, except that the upper surface of the needle head 11 is provided with an upwardly protruding first needle heel 5.
[0028] The upper surface of the tail of the needle bar 12 is provided with an upwardly protruding second needle heel 6.
[0029] Example 4
[0030] Similar to Embodiment 1, except that the end of the needle tail 13 connected to the needle bar 12 is provided with a bending notch 7. The bending notch 7 is located on the side of the needle tail 13, and the depth of the bending notch 7 is 50% of the thickness of the needle plate body.
[0031] The needle tail 13 is bent, and the angle between the axis of the needle tail 13 and the axis of the needle bar 12 is 3°. A certain bending angle is formed between the needle tail 13 and the needle bar 12, and a certain elasticity is reserved. The elasticity is used to make the needle selection plate body snap into the needle groove.
