Description

Technical Field

[0001] This utility model relates to the field of textile processing technology, and in particular to a weft tension adjustment mechanism for a warp knitting machine. Background Technology

[0002] When using a warp knitting machine, the tension of the yarn needs to be adjusted because the yarn has different sizes and shapes to prevent it from winding during knitting.

[0003] In the prior art, such as the utility model patent with publication number CN220450424U, a tension adjustment mechanism for a textile warp knitting machine is disclosed. In actual use, it only has the function of tension adjustment, which is relatively simple. In addition, the above-mentioned device cannot achieve automatic adjustment. If the tension of the yarn is insufficient or excessive, and the operator does not notice it in time, it is easy to cause the yarn to break or snap. Therefore, how to solve this problem needs to be considered. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a weft tension adjustment mechanism for a warp knitting machine. This adjustment mechanism has an automatic adjustment function during actual use, and will remind the operator when the tension is too high or too low, allowing for timely handling. In addition, it is equipped with a static electricity removal structure to prevent static electricity from affecting the quality of the finished product.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A weft tension adjustment mechanism for a warp knitting machine includes a mounting plate; a tension adjustment mechanism comprising a first guide roller symmetrically rotatably connected to the front side of the mounting plate; a first groove on the front side of the mounting plate containing a sliding strip that can slide up and down; a second groove on the front side of the sliding strip containing a conductive slider that can slide up and down; a guide rod fixedly connected between the upper and lower inner walls of the second groove, the guide rod passing through the conductive slider and slidably connected to the conductive slider; an upper end of the conductive slider being elastically connected to the inner top of the second groove via a spring; and a second guide roller rotatably connected to the front side of the conductive slider; a moving mechanism for moving the sliding strip up and down; and an antistatic removal mechanism for removing static electricity from the yarn surface.

[0007] Preferably, the moving mechanism includes a motor mounted on the upper end of the mounting plate, the output shaft of the motor extending into the first slide groove and fixedly connected to a threaded rod, the lower end of the threaded rod being rotatably connected to the inner bottom of the first slide groove, the threaded rod passing through the sliding bar and being threadedly connected.

[0008] Preferably, the motor is a servo motor with changeable direction.

[0009] Preferably, a connecting cover is fixedly connected to the front side of the mounting plate, a sealing door is installed on the front side of the connecting cover, and openings are provided on the left and right inner walls of the connecting cover.

[0010] Preferably, the electrostatic removal mechanism includes a negative ion fan installed on the upper end of the connecting cover, and the air outlet of the negative ion fan extends into the interior of the connecting cover.

[0011] Preferably, two conductive plates are installed on the inner walls of both sides of the second chute, with each pair of conductive plates at the same horizontal position cooperating, and an alarm is installed on the upper end of the connecting cover.

[0012] Compared with the prior art, the advantages of this utility model are as follows:

[0013] 1. By designing a tension adjustment mechanism incorporating a spring and a conductive slider, automatic adjustment of yarn tension is achieved. When the yarn tension changes, the conductive slider automatically moves up and down according to the increase or decrease in tension, thereby balancing and maintaining a suitable tension through the extension and contraction of the spring. This automatic adjustment mechanism effectively avoids yarn breakage or warp knitting quality problems caused by unstable tension, improving production efficiency and product quality.

[0014] 2. When the conductive slider moves to its limit position due to tension changes and contacts the upper and lower conductive plates, an alarm will be triggered. This design promptly alerts the operator that the current tension has exceeded the automatic adjustment range and requires manual intervention. This helps prevent equipment damage or product quality degradation caused by excessive or insufficient tension, enhancing production safety and controllability.

[0015] 3. Through the design of the negative ion fan, this device can generate a large number of negative ions during operation, effectively removing static electricity from the yarn surface. Eliminating static electricity not only reduces problems such as tangling and knotting of yarn caused by static adsorption, but also improves the working environment, reduces safety hazards caused by static electricity, and further enhances production efficiency and product quality.

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Reference Figures 1-3 A weft tension adjustment mechanism for a warp knitting machine, comprising a mounting plate 1;

[0022] The system also includes a tension adjustment mechanism, which includes a first guide roller 8 symmetrically rotatably connected to the front side of the mounting plate 1. A first groove 9 is provided on the front side of the mounting plate 1. A sliding strip 11 that can slide up and down is provided in the first groove 9. A second groove 13 is provided on the front side of the sliding strip 11. A conductive slider 17 that can slide up and down is provided in the second groove 13. A guide rod 16 is fixedly connected between the upper and lower inner walls of the second groove 13. The guide rod 16 passes through the conductive slider 17 and is slidably connected to the conductive slider 17. The upper end of the conductive slider 17 is elastically connected to the inner top of the second groove 13 by a spring 15. A second guide roller 12 is rotatably connected to the front side of the conductive slider 17.

[0023] It also includes a moving mechanism for moving the sliding bar 11 up and down. The moving mechanism includes a motor 7 mounted on the upper end of the mounting plate 1. The motor 7 is a servo motor that can change direction. The output shaft of the motor 7 extends into the first slide groove 9 and is fixedly connected to a threaded rod 10. The lower end of the threaded rod 10 is rotatably connected to the inner bottom of the first slide groove 9. The threaded rod 10 passes through the sliding bar 11 and is threaded. A first power supply for powering the motor 7 and the negative ion fan 5 is also provided here.

[0024] Among them, the front side of the mounting plate 1 is fixedly connected to the connecting cover 2, the front side of the connecting cover 2 is installed with the sealing door 4, and the left and right inner walls of the connecting cover 2 are provided with openings 3.

[0025] The system also includes an electrostatic removal mechanism for removing static electricity from the yarn surface. The electrostatic removal mechanism includes a negative ion fan 5 mounted on the upper end of the connecting cover 2, with the air outlet of the negative ion fan 5 extending into the interior of the connecting cover 2. Two conductive plates 14 are installed on the inner walls of both sides of the second slide groove 13, with each pair of conductive plates 14 at the same horizontal position engaging with each other. An alarm 6 is mounted on the upper end of the connecting cover 2. The system also includes a second power supply, with the negative terminal of the second power supply electrically connected to one pole of the alarm 6. The other pole of the alarm 6 is electrically connected to the two conductive plates 14 on the right side via two wires, and the positive terminal of the second power supply is electrically connected to the two conductive plates 14 on the left side via two wires.

[0026] In this invention, during use, the yarn enters from below the left first guide roller 8, passes above the second guide roller 12, and exits from below the right first guide roller 8. The spring 15 is in a stretched state, and the two sets of conductive plates 14 are located above and below the conductive slider 17, respectively. When the tension increases, the conductive slider 17 moves down and the spring 15 stretches more; when the tension decreases, the conductive slider 17 moves up and the spring 15 stretches less. This allows for automatic tension adjustment. When the conductive slider 17 moves up or down and contacts the corresponding two conductive plates 14, the alarm 6 will sound an alarm. This indicates that the automatic adjustment range of the spring 15 has reached its limit, and the automatic tension adjustment effect has deteriorated. At this time, the operator needs to start the motor 7 to adjust the position of the sliding bar 11, thereby effectively avoiding the situation where the tension is too small or too large, which would affect the overall warp knitting quality.

[0027] In addition, during the process, the negative ion fan 5 can be activated to allow a large number of negative ions to accumulate inside the connecting cover 2, thereby removing static electricity from the surface of the yarn.

[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
