TECHNICAL FIELD
[0001] The utility model relates to the field of flat knitting machine, especially to an extrusion 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 all installed through the penetrating steel wire, and the corresponding knitting needles are mutually matched 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 where the sinker is located.
[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 an extrusion type needle bed insert structure, which gives rise to the present case. CONTENT OF THE UTILITY MODEL
[0007] The utility model aims at providing an extrusion 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] An extrusion needle bed insert structure comprises
[0010] A needle plate is provided with a plurality of wide slots and narrow slots, and the wide slots and the narrow slots are arranged at intervals; wherein a thin insert is arranged in the narrow slot, the side surface of the thin insert is provided with a receiving groove, the needle is matched with the receiving groove, and a plurality of protrusions are arranged at the front end of the receiving groove, and the needle is matched with the adjacent protrusion when the needle moves.
[0011] The front end described herein refers to the end of the needle relative to the end of the needle plate, and in the working state, the needle plate is inclined, so it can also be regarded as the upper end; the width, the narrow, the thick and the thin are all relative to the size between the different slots and the inserts.
[0012] According to the actual production experience of the applicant, it is found that the shaking amplitude of the needle is the largest when the needle is moved after being stretched out of the needle plate during the needle turning and loop shifting, that is, the needle is more prone to vibration because the needle is more densely distributed and thinner; therefore, the receiving groove is processed on the thin insert to ensure that the operation of the needle in the needle plate is not affected, and after the needle is stretched out of the needle plate, a plurality of protrusions are arranged in the receiving groove to form a certain extrusion on the needle, thereby realizing the stable operation of the needle stretched out of the needle plate, and compared with the prior art, the processing of the receiving groove and the appropriate protrusions is easier to realize or modify.
[0013] Further, the receiving grooves are arranged on both side surfaces of the thin insert, and the protrusions are arranged in the receiving grooves.
[0014] Further, the receiving groove is provided with a through groove matched with the turning piece of the needle, and the protrusions are arranged above and below the through groove.
[0015] The needle with the turning piece occupies more space at the position of the turning piece, so the receiving groove can be additionally punched through to move the turning piece, and the receiving groove bottom and the protrusions are reserved above and below the turning piece to ensure the structural strength and the stability of the needle operation.
[0016] Further, at least two protrusions are arranged at intervals on the same side of the end of the needle plate.
[0017] Since the end of the needle plate is relatively long, at least two protrusions are arranged to ensure the stability of the needle operation.
[0018] Further, the surface of the protrusion is consistent with the surface of the thin insert on both sides of the receiving groove.
[0019] That is, the protrusion can be regarded as the part of the thin insert extending into the receiving groove.
[0020] After the above scheme is adopted, the utility model has the following advantages compared with the prior art:
[0021] The accommodating groove matching protrusion ensures stable operation of the knitting needle, facilitates actual production and processing, reduces production cost, and improves production efficiency. BRIEF DESCRIPTION OF DRAWINGS
