Description

Technical Field

[0001] This invention patent relates to a horizontal knitting needle plate and its processing technology. Background Technology

[0002] With the continuous development of textile technology, fine gauge flat knitting machines are being used more and more widely in the textile field. The core of fine gauge flat knitting machines is the needle plate structure. The needle plate structure mainly includes the needle plate, inserts, toothed sinkers, positioning wires, and knitting needles, long needles, spring needles, and control needles required for knitting. Parallel fixed-depth insert slots need to be milled on the upper surface of the needle plate. Inserts are installed in the insert slots, and toothed sinkers and other structural components are installed at the front end of the insert slots. Each pair of adjacent inserts forms a needle groove, and knitting needles, long needles, spring needles, and control needles are set in the needle groove.

[0003] According to its knitting principle (one stitch per stitch), a double-needle bed computerized flat knitting machine requires 24-needle and 28-needle computerized flat knitting machines to produce 12-needle and 14-needle sweaters with a large production volume. The needle plate and needle groove spacing of 24-needle and 28-needle machines are 1.058 (25.4 / 24) mm and 0.907 (25.4 / 28) mm, respectively. If more needles are needed, the needle plate and needle groove spacing becomes smaller and smaller, and the insert groove and insert groove wall become thinner and thinner. The needle plate and needle groove spacing of 36-needle machine is 0.706 (25.4 / 36) mm, and the thickness of the insert groove wall is 0.386 mm. This makes it difficult to process the insert groove of the needle plate, resulting in high processing costs, low processing efficiency, and high scrap rate. Similar processing difficulties exist for the needle plates of ultra-fine needle spacing in similar flat knitting glove machines. Summary of the Invention

[0004] The purpose of this invention is to solve the technical problems of existing fine-pitch needle plates by innovating the design of needle plate structural components and inventing a horizontal knitting needle plate and its processing technology.

[0005] A horizontal knitting needle plate includes a needle plate with a plurality of longitudinal first insert slots and second insert slots. A second insert slot is provided between adjacent first insert slots. The first insert slot is composed of a plurality of discontinuous first slots, and the second insert slot is composed of a plurality of discontinuous second slots. The first slots and the second slots are staggered.

[0006] Furthermore, the distance between adjacent first insert slots is multiple times the design pin pitch; the distance between adjacent second insert slots is multiple times the design pin pitch.

[0007] Furthermore, the first insert slot and the second insert slot are arranged alternately at equal intervals on the needle plate according to the setting.

[0008] Furthermore, the needle plate is provided with several transverse fitting grooves, and the mounting plate is fitted into the fitting grooves.

[0009] Furthermore, the mounting plate is provided with a second slot, and the second slot on the mounting plate located in several transverse fitting grooves is combined to form a second insert slot.

[0010] Furthermore, the first slot corresponds to the adjacent second slots of the same second insert slot; the second slot corresponds to the adjacent first slots of the same first insert slot.

[0011] Furthermore, the length of the first slot does not exceed the length between corresponding adjacent second slots in the same second insert slot; the length of the second slot does not exceed the length between corresponding adjacent first slots in the same first insert slot.

[0012] Furthermore, the first insert is installed in the first insert slot, and the second insert is installed in the second insert slot.

[0013] Furthermore, several first protrusions at the lower end of the first insert correspond to the first slot of the first insert groove, and several second protrusions at the lower end of the second insert correspond to the second slot of the second insert groove.

[0014] A horizontal knitting needle plate processing technology: The first step is to machine several transverse interlocking grooves on the needle plate; The second step is to machine several longitudinal first insert slots on the needle plate; The third step is to process the mounting plate that mates with the fitting groove; The fourth step is to machine the second insert slot on the mounting plate; Fifth step: Assemble the mounting plate into the fitting slot so that the corresponding second insert slot is located in the middle of the adjacent first insert slot.

[0015] The beneficial effects of this invention are as follows: the first insert slot of the needle plate and the second insert slot of the fitting mounting plate form a staggered structural design. As can be seen from the structure, this correspondingly increases the lateral thickness of the first and second insert slot walls, ensuring a high yield rate, improving production efficiency, and thus reducing processing costs. The design of the fitting mounting plate further enhances the ease of maintenance of the structural components. This innovative structure consolidates its leading position in the competition with peers. Attached Figure Description
