AI Technical Summary
The flat knitting machine produces large vibrations when turning the needles on the shaking table, causing the needles to shift and affecting the knitting effect.
A limiting protrusion is set on the needle plate. The limiting protrusion cooperates with the narrow slot to restrict the movement of the knitting needle and prevent deviation caused by vibration.
It improves the running accuracy and stability of the knitting needles, ensuring the stability of the knitting process.

TECHNICAL FIELD
[0001] The utility model relates to the field of flat knitting machine, especially to a structure for stabilizing knitting needles of a flat knitting machine. BACKGROUND
[0002] A computer flat knitting machine is a double needle plate latch needle weft knitting machine. The knitting needles in the needle bed (needle plate) needle slot are driven to move up and down along the needle slot during the reciprocating movement of the machine head along the guide rail, and the knitting of the fabric is completed under the cooperation of the cam mechanism and the pulling mechanism. The needle bed is also provided with an insert piece for limiting the knitting needles and can be replaced according to different knitting needles.
[0003] The front end of the needle plate is provided with a toothed piece, an inlay piece, and a sinker. The toothed piece, the inlay piece, and the sinker are installed through a steel wire and cooperate with the corresponding knitting needles to achieve better knitting effect. In order to provide installation space for the aforementioned toothed piece, inlay piece, sinker, and other elements, the insert piece does not extend to the needle bed head where the sinker is located.
[0004] The applicant proposed a flat knitting machine needle bed structure in 2024215065347, which adopts a structure of alternating thin and thick insert pieces, and has a relatively dense distribution of knitting needles. However, the applicant found that due to the large vibration generated during the rocking bed needle turning of the flat knitting machine, the knitting needles may be slightly offset, which may cause the needle turning (needle moving) to fail.
[0005] Therefore, the inventor made further research and developed a structure for stabilizing knitting needles of a flat knitting machine, which led to the present case. CONTENT OF THE UTILITY MODEL
[0006] The purpose of the utility model is to provide a structure for stabilizing knitting needles of a flat knitting machine, which can make the operation of the knitting needles more stable.
[0007] In order to achieve the above purpose, the technical scheme of the utility model is as follows:
[0008] A structure for stabilizing knitting needles of a flat knitting machine, comprising
[0009] A needle plate, a plurality of wide slots and narrow slots are formed on the needle plate, and the wide slots and narrow slots are arranged at intervals; the wide slots extend to the head of the needle plate, and a limiting protrusion is arranged between the wide slots at the head of the needle plate, and the limiting protrusion corresponds to the narrow slot.
[0010] The above structure is a further improvement based on the applicant's prior patent. In the prior patent, not every knitting needle needs to have a sinker, so the limiting protrusion can be set at the position without a sinker. By setting the limiting part, the knitting needle is limited, thereby avoiding large deviation due to vibration in the rocking bed working state.
[0011] Further, the limiting protrusions are in an integral structure with the needle plate and are continuous strip-shaped protrusions.
[0012] Further, the limiting protrusions are in an integral structure with the needle plate and are discontinuous protrusions.
[0013] The technical scheme can be regarded as cutting the continuous strip-shaped protrusion structure several times.
[0014] Further, the limiting protrusions are arranged in the grooves, the grooves are extensions of the wide slots, and the limiting protrusions protrude from the surface of the needle plate.
[0015] Further, the limiting protrusions are extensions of the thin inserts.
[0016] Further, the aforementioned limiting protrusions are 0.2-0.8 mm higher than the surface of the needle plate.
[0017] The limiting protrusions are too high to affect the avoidance of the turning-in inserts.
[0018] Further, the wide slots penetrate the head of the needle bed, and the narrow slots do not penetrate the head of the needle bed.
[0019] The wide slots and the narrow slots both penetrating the needle bed will reduce the strength of the needle bed, and the wide slots need to leave space for the movement of the sinkers, so the narrow slots do not penetrate the edge of the head of the needle bed.
[0020] Compared with the prior art, the utility model has the following advantages after the above scheme is adopted:
[0021] The two sides of the knitting needle are limited by the limiting protrusions, and the running accuracy and stability of the knitting needle during work are improved. BRIEF DESCRIPTION OF DRAWINGS

[0030] The utility model will be further explained in connection with the drawings and specific embodiments.
[0031] A structure of a stable needle of a flat knitting machine, comprising a needle plate 1, the needle plate 1 is provided with a plurality of wide slots 2 and narrow slots 3, the wide slots 2 and narrow slots 3 are arranged at intervals, the wide slots 2 are used for inserting thick inserts 5, and the narrow slots 3 are used for inserting thin inserts 6.
[0032] As shown in the first embodiment, Figure 1 the wide slots 2 extend to the inclined front end of the needle plate 1 (i.e. the position of the partial enlarged view A), and the narrow slots 3 stop at the position where the steel wire is installed at the front end of the needle plate 1, at this time, as shown in the partial enlarged view B, Figure 2 a limiting protrusion 4 is arranged between the wide slots 2 at the front end of the needle plate 1, the limiting protrusion 4 is 0.5 millimeters higher than the surface of the needle plate 1 and is on the same straight line as the narrow slots 3, so as to divide the end portions of the needles on both sides.
[0033] As shown in the second embodiment, Figure 3 the wide slots and narrow slots are also arranged at intervals, the thick inserts 5 are arranged in the wide slots, and the thin inserts 6 are arranged in the narrow slots, Figure 3 the left side shows a sinker 7 and a needle 8, and a limiting protrusion is also arranged between two adjacent needles 8, but the limiting protrusion here, as shown in the partial enlarged view C, Figure 4 extends to the head of the needle bed through the narrow slots 3 (but does not penetrate the needle bed, otherwise the strength of the needle bed will be reduced, and the wide slots 2 need to penetrate because the sinkers 7 need to be arranged), and the thin inserts 6 also extend to this position to form a limit (also refer to the partial enlarged view D). Figure 5
[0034] In the above two embodiments, the relative height of the limiting protrusion does not exceed 1 millimeter, and preferably does not exceed 0.8 millimeter, otherwise it will affect the avoidance of the turning piece.
[0035] The above is only a specific embodiment of the utility model, meanwhile, all the words such as "up, down, left, right, middle" in the utility model are only for reference, not absolute limitation, and any non-substantial change made by using the utility model should belong to the behavior of infringing the protection range of the utility model.
