Description

Technical Field

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

[0002] A knitting machine is a textile machine mainly used for weaving flat or three-dimensional garment pieces with specific shapes. During the weaving process, the knitting needles make regular lifting and lowering movements on the needle plate, and the yarns can be woven into knitted fabrics through the actions of the needle hooks and needle tongues. After searching, the Chinese patent authorization number CN209722437U discloses a tooth structure of a knitting machine, which can effectively control the swing of the tooth plate, reduce the deformation of the fabric on the knitting needles when shifting the circles, and thus effectively improve the stability of the knitting needle movement, avoid the impact on the fabric quality when weaving coarse and loose fabrics, and reduce the probability of fiber breakage. However, the needle plate grooves of traditional knitting machines are all through grooves. When making fine needles, the needle surface is small and soft and easy to deform, which affects the straightness of the needle and affects the needle turning and other needle techniques.

[0005] Preferably, both ends of the first slot are open through slots, one end of the second slot is closed, and a reinforcing surface is provided on the bottom surface of the end of the second slot. The reinforcing surface is an arc-shaped concave structure, and the reinforcing surface is located at one end of the needle plate body. The strength of the needle plate head is increased by the arc-shaped reinforcing surface.

[0006] Preferably, a toothed plate and an inlay are installed at the head of the second slot, a circular hole is opened in the middle of the toothed plate, and a downward-opening first hook is opened at the bottom of one end of the toothed plate, and the first hook is in contact with the surface of the needle plate at one end of the needle plate body, so that the toothed plate can be attached to the needle plate surface through the first hook.

[0007] Preferably, a second hook with a downward opening is provided at one end of the insert, and the second hook is in contact with the needle plate surface at one end of the needle plate body, so that the insert can be attached to the needle plate surface through the second hook.

[0008] Preferably, the outer contour of the end of the tooth mouth piece is consistent with that of the end of the inlay, the tooth mouth piece and the inlay are an integral stamping structure, and the tooth mouth piece and the inlay are provided with hook-shaped grooves, and the setting of the hook-shaped grooves facilitates the passage of yarn.

[0009] The utility model provides a needle plate structure of a flat knitting machine, which has the following beneficial effects:

[0010] (1) A needle plate structure of a knitting machine, wherein the needle plate slot of the needle plate is in the form of one through slot and one non-through slot. By setting one end of the second slot into a closed structure, the through slot at one end of the second slot is eliminated, thereby increasing the strength of the needle plate head, making the needle plate head less likely to deform, improving the straightness of the needle output, and effectively avoiding the phenomenon of being unable to turn the needle due to the needle output being not straight, thereby improving the quality of the woven fabric.

[0011] (2) This kind of knitting machine needle plate structure, by providing an arc-shaped reinforcement surface, provides an arc-shaped concave structure on the surface of one end of the needle plate, thereby increasing the strength of the needle plate head, which is beneficial to extending the service life of the needle plate.

[0012] This solves the problem that the traditional needle plate grooves of knitting machines are all through grooves, and when making fine needles, the needle contact surface is small, soft and easy to deform, which affects the straightness of the needle and affects the needle method such as needle transfer.
