Description

TECHNICAL FIELD

[0001] The utility model relates to the field of flat knitting machine, especially to a mounting structure of flat knitting machine insert piece. BACKGROUND

[0002] Computer flat knitting machine is a double needle plate weft knitting machine, through the machine head and the cam mechanism set on the cam bottom plate of the machine head, that is, the cam system reciprocates along the guide rail in the process of the machine head, drives the knitting needle set in the needle bed (needle plate) needle groove to move up and down along the needle groove, completes the knitting of the fabric under the cooperation of the cam mechanism and the pulling mechanism; wherein, the needle bed is also provided with an insert piece, which is used for limiting the knitting needle, and can be replaced according to different knitting needles.

[0003] As shown in the drawings in CN221320260U, because the length of the insert piece is relatively long, the insert piece is generally fixed at both ends by pressing strips (only the groove for installing the pressing strip is shown in the drawing, and the pressing strip itself is not shown), but even if the pressing strip is used for fixing, due to the density design requirement of the knitting needle, when the knitting needle is relatively dense and the insert piece is relatively thin, the insert piece will vibrate due to the vibration generated when the needle bed shakes, thereby affecting the normal work of the flat knitting machine.

[0004] In addition, the applicant proposes a flat knitting machine needle bed structure in 2024215065347, which adopts a structure of alternating thin and thick insert pieces, and only the front end corresponding to the thick insert piece is provided with a sinker, and the knitting needle is relatively dense; for this kind of needle bed with alternating thin and thick insert pieces, the inventor has further researched and developed a mounting structure of flat knitting machine insert piece, and the present case is generated. CONTENT OF THE UTILITY MODEL

[0005] The utility model aims at providing a mounting structure of flat knitting machine insert piece, which makes the structure of alternating thin and thick insert pieces more stable and convenient to install.

[0006] In order to achieve the above purpose, the technical scheme of the utility model is as follows:

[0007] A mounting structure of flat knitting machine insert piece, comprising

[0008] Thick insert piece, thin insert piece, thick insert piece and thin insert piece are arranged alternately and located in the insert slot of the needle plate, wherein the part of the thick insert piece located at the front end of the needle bed has an L-shaped structure, and the adjacent horizontal edge and vertical edge of the L-shaped structure are provided with positioning grooves, and the slot opening width of the positioning groove is less than or equal to the width of the groove bottom.

[0009] Here, the "front end" refers to the position of the needle bed end part extending from the needle plate; wide, narrow, thick and thin are relative to the size between different insert slots and insert pieces.

[0010] Due to the interval arrangement between the thin and thick inserts, the positioning groove (fixed by the positioning comb) for stabilizing the thick insert can also stabilize the thin insert, the positioning groove of the thin insert can not be processed into the same structure as the thick insert, only the positioning comb (also a plug gauge) can pass through; the L-shaped structure of the thick insert determines that the positioning groove can be arranged in the horizontal and vertical directions, and the positioning comb can be used in cooperation with each other, without the need for additional cover plates for fixation.

[0011] Further, the extension part is arranged on the side of the L-shaped structure of the thick insert, and the extension part and the L-shaped structure form a U-shaped avoiding space for limiting the movement of the sinker.

[0012] In the prior art, the sinker needs to be arranged at the front end of the thick insert, so the thick insert does not have a structure close to the front end of the needle bed, and the design considers the mounting and fixing mode of the thick insert and the space required by the sinker; the sinker arranged in this way is also more convenient to disassemble.

[0013] Further, the thick insert and the thin insert are further provided with a spacing piece, and the side of the spacing piece is also provided with a positioning groove.

[0014] Due to the relatively protruding L-shaped structure of the thick insert, although the corresponding protrusion can be arranged on the thin insert to form the positioning groove, the structure is far away from the needle plate, so the spacing piece is arranged to stabilize the insert.

[0015] Further, a plurality of through holes are arranged on the thick insert and the thin insert for the steel wire to pass through.

[0016] Further, a through groove is arranged on the spacing piece, and the through groove corresponds to the through hole.

[0017] The spacing piece occupies a small range, and the semi-closed through groove can be used as a through hole for the steel wire to pass through, and the whole steel wire does not need to be pulled out, and the spacing piece can be directly disassembled by rotating and moving.

[0018] Further, the positioning groove has an isosceles trapezoidal structure, and the two corners of the trapezoidal bottom are in arc shape.

[0019] Further, the spacing piece can be limited by the positioning comb in the positioning groove of the horizontal side after installation.

[0020] Compared with the prior art, the utility model has the following advantages after the above scheme is adopted:

[0021] The structure of the needle plate with the thin insert and the thick insert arranged alternately is optimized and designed, so that the installation convenience and the structural stability are improved. DRAWINGS
