Description

Technical Field

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

[0002] As a core piece of equipment in the textile industry, the precise adjustment of the needle bed of a warp knitting machine directly affects fabric density, loop uniformity, and product quality. Traditional adjustment methods have significant drawbacks: the sinker bed is usually rigidly fixed to the mounting frame by a group of bolts. During adjustment, dozens or even hundreds of bolts must be removed one by one, and then millimeter-level displacement can be achieved by manual tapping or prying. This process is time-consuming on average, and repeated disassembly and reassembly can easily lead to stripped threads and deformation of the mounting frame. More seriously, manual fine-tuning makes it difficult to ensure the consistency of the gap between the sinker and the knitting needles, which can cause uneven yarn tension, fabric texture distortion, and even needle breakage. Therefore, those skilled in the art provide a quick adjustment device for the needle bed of a warp knitting machine to solve the problems mentioned in the background art. Utility Model Content

[0003] The purpose of this invention is to provide a quick adjustment device for the needle bed of a warp knitting machine, thereby solving the problem of needle bed adjustment in the prior art.

[0004] This utility model provides the following technical solution: a quick adjustment device for the needle bed of a warp knitting machine, including a symmetrically arranged mounting frame and a settling sheet bed symmetrically sleeved in the middle of the mounting frame. The top of the two sets of settling sheet beds are fixedly installed with mounting shafts, and mounting side plates are provided at both ends of the outer side of the mounting shafts. An adjustment component for adjusting the position of the mounting shafts by means of a motor is provided on the outer side of one set of mounting side plates.

The two sets of mounting side plates are respectively connected to the two ends of the outer side of the mounting shaft through the two sets of central grooves.

[0006] As a preferred embodiment of the above technical solution, the mounting side plate is fitted with a return spring through a central groove, and a support plate is fixedly mounted on the top of the return spring, with the top of the support plate in contact with the bottom of the mounting shaft.

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0020] Please see Figure 1 - Figure 5 As shown, this utility model provides a technical solution: a quick adjustment device for the needle bed of a warp knitting machine, including symmetrically arranged mounting frames 2 and symmetrically fitted sinker beds 3 in the middle of the mounting frames 2. The two sets of mounting frames 2 are radially symmetrically distributed. The top of the two sets of sinker beds 3 are fixedly installed with mounting shafts 4, and mounting side plates 1 are provided at both ends of the outer side of the mounting shafts 4. An adjustment component that adjusts the position of the mounting shafts 4 by means of a motor is provided on the outer side of one set of mounting side plates 1.

[0021] As one implementation method in this embodiment, please refer to Figure 3 and Figure 4 As shown, a central groove 6 extending inward is provided at the top center of the mounting side plate 1, and mounting grooves 7 are symmetrically provided about the central groove 6 in the upper middle part of the mounting side plate 1, and the mounting grooves 7 are connected to the central groove 6. The two sets of mounting side plates 1 are respectively connected to the two ends of the outer side of the mounting shaft 4 through the two sets of central grooves 6; the central grooves 6 facilitate the limitation of the movement of the mounting shaft 4.

[0022] The mounting side plate 1 is fitted with a return spring 8 through the central groove 6. A support plate 9 is fixedly installed on the top of the return spring 8, and the top of the support plate 9 is in contact with the bottom of the mounting shaft 4. Both ends of the support plate 9 pass through the connecting groove between the central groove 6 and the mounting groove 7 and extend into the interior of the mounting groove 7. The return spring 8 and the support plate 9 facilitate buffering when the mounting shaft 4 slides, and can also assist in its reset after sliding.

[0023] A recessed groove 12 is provided on one side of the top of the mounting side plate 1. A cylinder 11 is sleeved on the mounting side plate 1 through a set of mounting slots 7. The output end of the cylinder 11 extends through the top of the mounting side plate 1 into the interior of the groove 12. The top of the output end of the cylinder 11 is recessed. A pad 10 is fixedly installed at the bottom of the cylinder 11, and both ends of the pad 10 are fixedly connected to the mounting side plate 1.

[0024] As one implementation method in this embodiment, please refer to Figure 4 and Figure 5 As shown, the adjustment assembly includes a drive motor 5 fixedly installed on the outside of the mounting side plate 1. A second sleeve 14 is fixedly installed at the output end of the drive motor 5. An outwardly extending square shaft 15 is sleeved inside the second sleeve 14. Connecting springs 16 are fixedly installed at both ends of the square shaft 15. The square shaft 15 is connected to the inner wall of the second sleeve 14 through a set of connecting springs 16.

[0025] The other end of the square shaft 15 is fitted with a first sleeve 13. The square shaft 15 is fixedly connected to the inner wall of the first sleeve 13 by another set of connecting springs 16. The first sleeve 13, the second sleeve 14 and the square shaft 15 are all inclined. The inner side of the first sleeve 13 is fixedly connected to one end of the mounting shaft 4.

[0026] Working principle: When in use, start the drive motor 5, which drives the second sleeve 14 installed at its output end to rotate clockwise. This causes the first sleeve 13 and the mounting shaft 4 fixedly installed with the first sleeve 13 to shift through the square shaft 15 fitted inside the second sleeve 14. Since the mounting shaft 4 is limited by the central groove 6 when it moves, and the first sleeve 13 and the second sleeve 14 will stretch the connecting spring 16 when they rotate under the drive motor 5, the mounting shaft 4 will move along the central groove 6 and squeeze the return spring 8, thereby adjusting the position of the sinking plate bed 3 and the mounting frame 2 installed at the bottom of the mounting shaft 4, so as to achieve the control of the yarn.

[0027] If the sedimentation bed 3 needs to be replaced, start the drive motor 5 in reverse to drive the mounting shaft 4 to rotate counterclockwise, thereby forcing the mounting shaft 4 to move into the groove 12 and contact the cylinder 11. This makes it easier to replace the sedimentation bed 3. After the replacement is completed, start the cylinder 11 to extend it and push the mounting shaft 4. Then start the drive motor 5 clockwise to reset the mounting shaft 4.

[0028] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
