A knitting track adjustment device for a knitting machine

Abstract

This utility model discloses a knitting track adjustment device for a knitting machine, relating to the field of knitting machine technology. It includes a guide rail adjustment assembly, one end of which is equipped with a pressure roller assembly. Both the guide rail adjustment assembly and the pressure roller assembly are fixedly connected to the machine housing. The guide rail adjustment assembly includes a horizontal plate, with an arc-shaped guide rail on the side of the horizontal plate closest to the machine housing. A transverse sliding groove is provided in the middle of the horizontal plate, and an arc-shaped groove is provided on the arc-shaped guide rail. After loosening two nuts, the transverse sliding bolt and the positioning bolt can move along the transverse sliding groove, thereby changing the position of the arc-shaped guide rail and improving its applicability.

When the arc-shaped guide rail rotates, the positioning bolt slides in the arc-shaped groove, preventing the positioning bolt from obstructing the arc-shaped guide rail and ensuring its normal rotation.

Description

Technical Field

[0001] This utility model relates to the field of knitting machine technology, specifically a knitting track adjustment device for a knitting machine. Background Technology

[0002] A knitting machine is a textile machine that uses knitting needles to form loops of yarns of various raw materials and varieties, and then connects them to form knitted fabrics. The knitting track is a key component of the knitting machine, which is mainly responsible for guiding and controlling the knitting direction, ensuring that the knitting needles or materials can move along a predetermined path and sequence to form the desired knitted structure.

[0003] Currently, knitting tracks are mainly divided into tracks for guiding the movement of knitting needles and tracks for guiding the movement of materials. Tracks for guiding the movement of materials are mainly used for sewing materials or changing the shape of materials and the shape of the material's containment space through knitting. Taking sofa cover knitwear as an example, sofas of different sizes and shapes require different cover knitwear shapes and containment spaces. During the sewing stage, different knitting tracks are needed to change the shape and containment space of the cover knitwear. However, the current knitting tracks used to guide material movement have fixed tracks, so the shape of the material formed after processing is also fixed, which cannot meet the needs of diversified knitting work. In order to ensure the stability of the knitting track, the current knitting track is generally fixed on the knitting machine using bolts and other connectors. It is quite troublesome to replace the knitting track in order to improve the diversity of knitting work. Utility Model Content

[0009] As a further technical solution of this utility model, the pressure roller is rotatably connected to the second connecting shaft, and the top of the second connecting shaft is fixedly connected to one end of the rotating frame.

[0010] As a further technical solution of this utility model, the bottom of the middle section of the rotating frame is fixedly connected to the fourth connecting shaft, and the end of the fourth connecting shaft away from the rotating frame is rotatably connected to the positioning frame; the end of the positioning frame away from the fourth connecting shaft is integrally fixedly connected to the mounting base, and the mounting base is fixedly connected to the chassis.

[0013] Compared with the prior art, the beneficial effects of this utility model are: 1. In this utility model, the transverse bolt and the positioning bolt, together with the nut connected to their threads, allow the arc-shaped guide rail to be tightly connected to the horizontal plate, preventing the arc-shaped guide rail from shaking or shifting. After loosening the two nuts, the transverse bolt and the positioning bolt can move along the transverse groove, thereby changing the position of the arc-shaped guide rail and improving its applicability. In addition, after loosening the two nuts, the arc-shaped guide rail can also rotate around the transverse bolt as the center, thereby changing the curvature of the arc-shaped guide rail, so that the material can also change the curvature after stitching under the guidance of the arc-shaped guide rail. When the arc-shaped guide rail rotates, the positioning bolt slides in the arc groove, so that the positioning bolt does not obstruct the arc-shaped guide rail and ensures that the arc-shaped guide rail can rotate normally.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-7 In this embodiment of the present invention, a knitting track adjustment device for a knitting machine includes a guide rail adjustment component 1, one end of which is provided with a pressure roller component 2; both the guide rail adjustment component 1 and the pressure roller component 2 are fixedly connected to the machine housing 4. The guide rail adjustment assembly 1 includes a horizontal plate 12, and an arc-shaped guide rail 11 is provided on the side of the horizontal plate 12 near the chassis 4; a horizontal sliding groove 15 is provided in the middle of the horizontal plate 12, and an arc-shaped groove 16 is provided on the arc-shaped guide rail 11.

The outer side of the transverse bolt 17 and the positioning bolt 18 away from the arc-shaped guide rail 11 is threaded with a nut 19, and both nuts 19 are in contact with the side of the transverse plate 12 away from the arc-shaped guide rail 11. The top of the arc-shaped guide rail 11 is arc-shaped, and the end of the positioning bolt 18 away from the horizontal plate 12 is integrally provided with a nut, which fits against the side of the arc-shaped guide rail 11 away from the horizontal plate 12.

The end of the connecting shaft 13 away from the horizontal plate 12 is fixedly connected to the output shaft of the servo motor 14. The servo motor 14 is fixedly connected to the chassis 4.

[0025] By adopting the above technical solution, the transverse bolt 17 and the positioning bolt 18, together with the nut 19 connected to their threads, can tightly connect the arc-shaped guide rail 11 with the horizontal plate 12, preventing the arc-shaped guide rail 11 from shaking or shifting. After loosening the two nuts 19, the transverse bolt 17 and the positioning bolt 18 can move along the transverse groove 15, thereby changing the position of the arc-shaped guide rail 11 and improving the applicability of the arc-shaped guide rail 11. In addition, after loosening the two nuts 19, the arc-shaped guide rail 11 can also rotate around the transverse bolt as the center, thereby changing the curvature of the arc-shaped guide rail 11, so that the material can also change the curvature after sewing under the guidance of the arc-shaped guide rail 11. When the arc-shaped guide rail 11 rotates, the positioning bolt 18 slides in the arc-shaped groove 16, so that the positioning bolt 18 will not obstruct the arc-shaped guide rail 11, ensuring that the arc-shaped guide rail 11 can rotate normally.

[0026] In this embodiment, the pressure roller assembly 2 includes a pressure roller 21, which corresponds to the position of the knitting needle on the machine head 3, and the pressure roller 21 is located on the side of the knitting needle away from the arc-shaped guide rail 11; The pressure roller 21 is rotatably connected to the connecting shaft 22 on the same axis, and the top of the connecting shaft 22 is fixedly connected to one end of the rotating frame 23. The bottom of the middle section of the rotating frame 23 is fixedly connected to the connecting shaft 29. The end of the connecting shaft 29 away from the rotating frame 23 is rotatably connected to the positioning frame 24. The end of the positioning frame 24 away from the connecting shaft 29 is integrally fixedly connected to the mounting base 25, which is fixedly connected to the chassis 4. The bottom of the rotating frame 23 away from the pressure roller 21 is fixedly connected to the connecting shaft 28. The bottom of the connecting shaft 28 is rotatably connected to the connecting member 20. The end of the connecting member 20 away from the connecting shaft 28 is fixedly connected to the telescopic shaft of the cylinder 26. The end of the cylinder 26 away from the connector 20 is rotatably connected to the L-shaped frame 27, and the end of the L-shaped frame 27 away from the cylinder 26 is fixedly connected to the chassis 4, and the middle section of the chassis 4 is provided with reinforcing ribs.

[0027] By adopting the above technical solution, the pressure roller 21 plays the role of pressing the material, increasing the tension of the material, ensuring that the material is always in a flat state at the knitting needle, and ensuring the normal operation of the knitting work; the positioning frame 24 plays the role of supporting the rotating frame 23, and at the same time allows the rotating frame 23 to rotate around the connecting shaft 4 29 as the center, thereby changing the distance between the pressure roller 21 and the machine box 4, so that the pressure roller 21 can press materials of different thicknesses.

[0028] The working principle of this utility model is as follows: the transverse bolt 17 and the positioning bolt 18, in conjunction with the nut 19 threadedly connected to them, allow the arc-shaped guide rail 11 to be tightly connected to the horizontal plate 12, preventing the arc-shaped guide rail 11 from shaking or shifting; after loosening the two nuts 19, the transverse bolt 17 and the positioning bolt 18 can move along the transverse groove 15, thereby changing the position of the arc-shaped guide rail 11 and improving the applicability of the arc-shaped guide rail 11; in addition, after loosening the two nuts 19, the arc-shaped guide rail 11 can also rotate around the transverse bolt as the center, thereby changing the curvature of the arc-shaped guide rail 11, so that the material can also change the curvature after sewing under the guidance of the arc-shaped guide rail 11; when the arc-shaped guide rail 11 rotates, the positioning bolt 18 slides in the arc-shaped groove 16, so that the positioning bolt 18 will not obstruct the arc-shaped guide rail 11, ensuring that the arc-shaped guide rail 11 can rotate normally; The pressure roller 21 presses down the material, increases the tension of the material, and ensures that the material is always flat at the knitting needle, thus ensuring the normal operation of the knitting work. The positioning frame 24 supports the rotating frame 23 and allows the rotating frame 23 to rotate around the connecting shaft 4 29 as the center, thereby changing the distance between the pressure roller 21 and the machine box 4, so that the pressure roller 21 can press materials of different thicknesses.

[0029] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style of the specification is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other implementations that can be understood by those skilled in the art.
