Description

Technical Field

[0001] The utility model relates to the field of flat knitting machines, in particular to a needle bed structure of a flat knitting machine. Background Art

[0002] The computerized flat knitting machine is a double-needle plate latch needle weft knitting loom. Through the machine head and the triangular mechanism arranged on the triangular bottom plate of the machine head, that is, the triangular system, when the machine head reciprocates along the guide rail, the knitting needles arranged in the needle grooves on the needle plate are driven to move up and down along the needle grooves, and the weaving of the fabric is completed with the cooperation of the triangular mechanism and the pulling mechanism.

[0003] A tooth plate, an inlay plate and a sinker are arranged at the front end of each needle groove. The tooth plate, the inlay plate and the sinker are all installed by threading steel wires and cooperate with the corresponding knitting needles to achieve a better knitting effect.

[0004] The distance (needle pitch) between adjacent knitting needles arranged along the length of the needle plate usually directly affects the density of fabric weaving. As more knitting needles are distributed on a needle plate, the thickness of each component itself needs to be thinner, which in turn affects the structural strength of the component itself and makes it more difficult to manufacture and process.

[0005] Therefore, the inventor conducted further research and developed a needle bed structure for a flat knitting machine, which resulted in the present invention. Utility Model Content

[0006] The utility model aims to provide a needle bed structure of a flat knitting machine, which simplifies the needle bed structure while meeting the required knitting function.

[0007] In order to achieve the above purpose, the technical solution of the utility model is as follows:

[0008] A flat knitting machine needle bed structure, comprising

[0009] The needle plate and the insert are provided with a wide slot and a narrow slot, the wide slot and the narrow slot are spaced apart from each other, and the wide slot and the narrow slot are evenly distributed on the needle plate in sequence, a wide insert is provided in the wide slot, and a narrow insert is provided in the narrow slot, the space between the wide insert and the narrow insert is used to set the knitting needles, and a sinker and a tooth plate are also provided at the top of the wide slot corresponding to the wide insert.

[0010] Since the knitted fabrics involved in flat knitting machines now almost all use the loop transfer process, which is to transfer the loop on the knitting needle of one needle bed to the knitting needle of another adjacent needle bed; therefore, in this way, not every knitting needle needs to have a sinker; by redesigning the slots, the slot width of the wide slot is larger than the slot width of the narrow slot, so that the widths of adjacent slots are different, while ensuring the strength of each component, the "needle distribution density" is increased as much as possible; the insert is generally also called an inlay.

[0011] Furthermore, the gap between the wide insert and the narrow insert is defined as a needle slot, and all needle slots have the same width.

[0012] Furthermore, the sides of the wide insert and the narrow insert are both provided with air-avoiding grooves.

[0013] The air avoidance groove is used to accommodate a needle transfer piece, and the needle transfer piece is arranged on one side of the knitting needle and is used for receiving the needle and transferring the loop.

[0014] Furthermore, the sinker is penetrated by the same steel wire or steel column.

[0015] Furthermore, the depth of the air avoidance groove on the wide insert is greater than the depth of the air avoidance groove on the narrow insert.

[0016] After adopting the above scheme, the utility model has the following advantages compared with the prior art:

[0017] While ensuring the strength of each component, the needle distribution density is increased as much as possible and the required knitting functions are met. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0028] In this embodiment, no special design is made to the structures of the knitting needles, sinkers, tooth plates and other components themselves, which can be regarded as conventional technologies.

[0029] like Figure 1-2As shown, a needle bed structure of a flat knitting machine includes a needle plate 1, a wide slot 12 and a narrow slot 11 are provided on the needle plate 1, wherein a wide insert 22 is provided in the wide slot 12, and a narrow insert 21 is provided in the narrow slot 11, and the gap between the wide insert 22 and the narrow insert 21 is used to set the knitting needles, and a sinker 3 and a tooth plate 4 are also provided at the end of the wide slot 12 corresponding to the wide insert 22, and the sinker 3 and the tooth plate 4 are all passed through by the same steel wire 31,

[0030] The gap where the knitting needle 5 is located is generally called a needle groove. The width of each needle groove is the same, and the thickness of the wide insert 22 is greater than that of the narrow insert 21. Similarly, the groove depth of the air avoidance groove 221 opened on the side of the wide insert 22 is also greater than the groove depth of the air avoidance groove 211 opened on the side of the narrow insert 21.

[0031] When this embodiment works, refer to Figure 3 , 4 According to the working state, the knitting needles can be divided into yarn-eating knitting needles 51 and loop-storing knitting needles 52. The loop-storing knitting needles 52 are correspondingly provided with sinkers 3 and tooth-mouth pieces 4. Figure 4 Taking the direction shown as an example, when the rear head 7 moves rightward and the front head 6 moves leftward, the coils are transferred between the yarn-taking needles 51, and the coil-storing needles 52 cooperate with the sinker 3 to work.

[0032] The above are only specific embodiments of the present utility model. At the same time, all words such as "upper, lower, left, right, middle" involved in the present utility model are for reference only and are not absolutely limiting. Any non-substantial changes made using the present utility model shall be deemed as an infringement of the protection scope of the present utility model.
