Description

Technical Field

[0001] This utility model relates to the field of yarn tensioning technology, and in particular to a yarn tensioning device with an adjustment mechanism. Background Technology

[0002] In textile production, precise control of yarn tension is a key factor in ensuring product quality and production efficiency. Traditional yarn tension adjustment devices use screws or springs to adjust the tension, enabling balanced yarn movement.

[0003] However, in actual operation of tension adjustment, relying on screw adjustment requires manual adjustment. Mechanical adjustment mechanisms have a slow response speed, and staff need to spend a long time at the yarn, which is labor-intensive. Using spring adjustment, due to the limitation of spring force, it is difficult to achieve precise control of yarn tension, resulting in uneven tension and a tendency for adjustment to lag, which can easily lead to problems such as yarn breakage and loosening. Utility Model Content

[0004] The purpose of this invention is to provide a yarn tensioning device with an adjustment mechanism to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a yarn tensioning device with an adjusting mechanism, comprising:

[0006] Mounting plate;

[0007] A tension sensor, which is mounted in the middle of the mounting plate;

[0008] An adjustment mechanism is provided on both sides of the tension sensor and is used for adjusting the tension of the yarn.

[0009] A drive mechanism is mounted on the back of the mounting plate and is used for synchronous adjustment relative to the two adjustment mechanisms.

[0010] Preferably, the adjustment mechanism includes:

[0011] Adjusting rods, with two adjacent adjusting rods respectively disposed on both sides of the tension sensor;

[0012] A guide wheel, which is rotatably inserted through the middle of the adjusting rod via a bearing;

[0018] A positioning pin, which is rotatably inserted into one end of the connecting plate;

[0019] A limiting shaft is rotatably inserted into the other end of the connecting plate;

[0020] Multiple toothed blocks are fixed at the other end of the connecting plate in an arc-shaped structure at equal intervals.

[0021] Preferably, the positioning pin is fixedly inserted into one end of the adjusting rod, and the limiting shaft is fixed to the back of the mounting plate.

[0022] Preferably, the drive mechanism includes:

[0026] The technical effects and advantages of this utility model are as follows:

[0027] This invention employs a combination of a tension sensor, a connecting mechanism, and a drive mechanism. The tension sensor is linked with the electric telescopic rod to achieve real-time monitoring and automatic adjustment, forming a closed-loop control circuit to ensure precise and stable tension.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0033] This utility model provides, for example Figure 1-3 The yarn tensioning device with an adjustment mechanism shown includes: a mounting plate 1, a tension sensor 2, an adjustment mechanism 3, and a drive mechanism 4. The tension sensor 2 is installed in the middle of the mounting plate 1 and is electrically connected to an external power supply through an external controller to facilitate tension sensing of the yarn moving on the tension sensor 2. The adjustment mechanism 3 is located on both sides of the tension sensor 2 and is used for adjusting the tension of the yarn. The drive mechanism 4 is installed on the back of the mounting plate 1 and is used for synchronous adjustment relative to the two adjustment mechanisms 3.

[0034] The adjustment mechanism 3 includes an adjustment rod 31, a guide wheel 32, a movable groove 33, and a connecting assembly 34. Two adjacent adjustment rods 31 are respectively arranged on both sides of the tension sensor 2. The guide wheel 32 is inserted through the middle of the adjustment rod 31 via a bearing. Two movable grooves 33 are respectively opened on both sides of the front of the mounting plate 1. The adjustment rod 31 is slidably inserted into the inner cavity of the movable groove 33. By sliding the adjustment rod 31, the yarn that slides crosswise on the two adjustment rods 31 and the tension sensor 2 can be tensioned. The closer the two adjustment rods 31 and the tension sensor 2 are to being horizontal, the closer the yarn tension is to being balanced. The two adjustment rods 31 and the tension sensor 2 are arranged in a triangular structure. The larger the isosceles side, the tighter the tension between the yarns is. Two connecting assemblies 34 are respectively arranged on both sides of the drive mechanism 4.

[0035] Furthermore, the connecting assembly 34 is disposed between the adjusting rod 31 and the driving mechanism 4. The connecting assembly 34 includes a connecting plate 341, a positioning pin 342, a limiting shaft 343, and toothed blocks 344. The connecting plate 341 is disposed on the back of the mounting plate 1, and the driving mechanism 4 is disposed between the two opposite connecting plates 341. The positioning pin 342 is rotatably inserted into one end of the connecting plate 341, and the limiting shaft 343 is rotatably inserted into the other end of the connecting plate 341. Multiple toothed blocks 344 are equidistantly fixed to the other end of the connecting plate 341 in an arc-shaped structure. The positioning pin 342 is fixedly inserted into one end of the adjusting rod 31. The limiting shaft 343 is fixed to the back of the mounting plate 1. The limiting shaft 343 facilitates the position limitation of the other end of the connecting plate 341. The meshing of the toothed blocks 344 with the structure on the driving mechanism 4 ensures that the connecting plate 341 maintains a stable structure, which facilitates the stability of the position of the adjusting rod 31.

[0036] Specifically, the drive mechanism 4 includes an electric telescopic rod 41, a bidirectional rack 42, and a positioning post 43. The electric telescopic rod 41 is fixed to the top of the mounting plate 1, and the bidirectional rack 42 is fixed to the telescopic end of the electric telescopic rod 41. The two sides of the bidirectional rack 42 are respectively engaged with the outer walls of adjacent tooth blocks 344. The positioning post 43 is fixed to the middle of the back of the mounting plate 1, and the positioning post 43 is slidably inserted into the middle of the bidirectional rack 42. The positioning post 43 facilitates the bidirectional rack 42 to reciprocate up and down under the action of the electric telescopic rod 41, improving the stability of the position of the bidirectional rack 42. Furthermore, the bidirectional rack 42 is connected to the tooth blocks 344 through the electric telescopic rod 41. The engagement of the two connecting plates 341 facilitates synchronous movement of the two adjusting rods 31, improving the stability of yarn tension. The electric telescopic rod 41 is connected to the tension sensor 2 via a controller. When the tension sensor 2 detects yarn slack, the electric telescopic rod 41 is driven to push down or move up the two adjusting rods 31 to balance the yarn tension. When the yarn tension is too high, the electric telescopic rod 41 drives the bidirectional rack 42 to move the two adjusting rods 31 towards the horizontal extension line of the tension sensor 2, preventing the yarn tension from becoming too tight and improving the convenience of tension adjustment.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
