AI Technical Summary
The existing needle plate structure of the flat knitting machine is prone to vibration during the needle turning process, which causes the knitting needles to deviate and affects the knitting stability. At the same time, it is difficult to process the limiting protrusions and improper thickness of the inserts can lead to excessive or unstable running resistance of the knitting needles.
The needle bed insert structure is clamped, and thick inserts and thin inserts are installed in wide slots and narrow slots on the needle plate, respectively. Clamping parts are set at the ends of the inserts to provide stable guidance, avoid sinker space and needle space, and reduce processing difficulty.
It improves the stability of the knitting needles during the needle flipping and loop shifting process, reduces the difficulty of production and processing, and ensures smooth operation of the knitting needles.

TECHNICAL FIELD
[0001] The utility model relates to the field of flat knitting machine, especially to a clamping type needle bed insert structure. BACKGROUND
[0002] The 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, and 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, which is used for limiting the knitting needle, and can be replaced according to different knitting needles.
[0003] The front end of the needle plate is provided with a toothed piece, an insert and a sinker, the toothed piece, the insert and the sinker are installed through the penetrating steel wire, and the corresponding knitting needles are matched with each other to achieve better knitting effect, in order to leave installation space for the aforementioned toothed piece, insert and sinker, therefore, the insert cannot extend to the needle bed head part of the sinker.
[0004] The applicant puts forward a flat knitting machine needle bed structure in 2024215065347, which adopts the structure of alternating thin and thick inserts, and only the front end corresponding to the thick insert is provided with a sinker, and the distribution of the knitting needles is relatively dense, in the subsequent production test, the applicant finds that when the flat knitting machine is in the needle turning state, it will produce a large vibration, which will cause a slight deviation of the knitting needle, and may cause the failure of needle turning (needle moving); therefore, in 202422896980X, the applicant puts forward a structure for stabilizing the knitting needle of the flat knitting machine, which sets a limiting protrusion (including extending the thin insert to the head part of the needle plate) between the wide insert slots at the head part of the needle plate, so as to make the operation of the knitting needle more stable.
[0005] However, in the subsequent processing, the applicant finds that it is difficult to process the limiting protrusion directly on the needle plate in the actual production and processing process, and when the thin insert is extended to the head part of the needle plate, the insert is too thick to cause too much resistance to the operation of the knitting needle, and the insert is too thin to produce actual effect.
[0006] Therefore, the inventor makes further research on this and develops a clamping type needle bed insert structure, which gives rise to the present case. CONTENT OF THE UTILITY MODEL
[0007] The utility model aims at providing a clamping type needle bed insert structure, which can ensure the stable operation of the knitting needle and facilitate production and processing.
[0008] In order to achieve the above purpose, the technical scheme of the utility model is as follows:
[0009] A clamping type needle bed insert piece structure comprises
[0010] A needle plate is provided with a plurality of wide slots and narrow slots, the wide slots and the narrow slots are arranged at intervals, thick insert pieces are arranged in the wide slots, and thin insert pieces are arranged in the narrow slots.
[0011] The end of the thick insert piece is provided with a first clamping part, the end of the thin insert piece is provided with a second clamping part, the first clamping part and the second clamping part are located opposite to the front end of the needle plate, the first clamping part and the thick insert piece body form a first avoiding space, and a second avoiding space is formed below the second clamping part.
[0012] The "front end" described herein refers to the position of the needle bed end part extending from the needle plate (i.e. close to the needle plate hole), which can also be regarded as the upper end in the working state since the needle plate is inclined; the wide, narrow, thick and thin are all relative sizes between different slots and insert pieces.
[0013] In the prior design of the applicant, there is no first clamping part and second clamping part, and here the first clamping part and the second clamping part are added, and the first avoiding space is designed to avoid the sinker, and the second avoiding space is designed to avoid the needle turning piece, so that the first clamping part and the second clamping part can be as long as possible to the front end of the needle plate. The "clamping part" here does not clamp the needle, but only guides the needle path and stabilizes its operation.
[0014] Further, the first clamping part is further provided with a first groove, and the first groove is located below the first avoiding space.
[0015] The first avoiding space is used to provide space for the sinker to swing, and the first groove is used to arrange the sinker, which plays a role in reasonably utilizing space.
[0016] Further, the first clamping part is a sheet-shaped L-shaped structure, the first avoiding space formed by the first clamping part and the thick insert piece body is U-shaped, and the first groove is a straight line structure.
[0017] Further, the second clamping part is a sheet block structure, and the second avoiding space is a straight line structure.
[0018] Further, a spacing piece is arranged between the thick insert piece and the thin insert piece.
[0019] The thick insert piece and the thin insert piece are separated by the spacing piece, so that after the entire needle plate insert piece assembly is completed, the insert pieces on the left and right sides of the needle plate near the hole opening are basically not shaken, the needle can be protected, and the needle can be prevented from tilting left and right.
[0020] Further, the thick insert piece is further provided with a second groove, and the second groove is located on the other side of the first groove.
[0021] The second groove is used for avoiding the thick insert piece.
[0022] Compared with the prior art, the utility model has the following advantages:
[0023] Through the reasonable setting clamping part, still can receive the stable action (not clamping dead) of clamping part when the knitting needle runs to the front end of the needle plate, thereby improving the stability of the knitting needle in the process of turning needle and shifting circle, and the processing difficulty of the insert piece is far lower than the processing of the needle plate itself.
