Description

Technical Field

[0001] This utility model relates to the field of air-coated yarn technology, specifically to an air-coated yarn tension tester. Background Technology

[0002] Air-coated yarn is a composite yarn formed by regularly winding outer fibers such as nylon and polyester with core fibers such as spandex using compressed air. It has a soft and smooth feel. During the production process, its tension needs to be tested with a tension tester to ensure the quality of the finished product.

[0003] For example, Chinese Patent CN102706502A discloses a tension detection system for yarn in textile machinery, which includes a tension sensor, a data acquisition module, an A / D conversion module, a DSP processing module, and a display module connected in sequence. It also includes a data storage module connected to the DSP processing module. The tension sensor used is a resistive tension sensor. This invention solves the problem that the existing technology for testing yarn tension typically uses manual measurement methods, which are not only inaccurate but also inefficient. By using a sensor to detect yarn tension parameters during various processing stages, the DSP processing module processes the data and displays it on the display module for operator reference. Relevant parameters are also stored in a storage module for later research and adjustment, achieving real-time monitoring of yarn tension and improving measurement accuracy and production efficiency. Traditional tension testers use a three-wheel structure, where pressure rollers on both sides pull the yarn, causing it to press against the sensing roller to measure its tension. However, the pressure rollers lack a locking structure for vertical movement, making them susceptible to external force during transport, leading to repeated vertical movement, increased wear, and reduced stability and lifespan. Therefore, an air-coated yarn tension tester is proposed to solve the above problems. Utility Model Content

[0004] (a) Technical problems to be solved To address the shortcomings of existing technologies, this invention provides an air-coated yarn tension tester with advantages such as improved locking effect, solving the problem of easy movement of traditional pressure rollers during transport.

[0005] (II) Technical Solution To achieve the aforementioned specific locking effect, this utility model provides the following technical solution: an air-coated yarn tension tester, comprising a body, a mounting frame at the top of the body, two sets of pressure rollers mounted on the outer surface of the top of the mounting frame, a mounting rod at the center of the top of the body, a sensing wheel mounted on the outer surface of the top of the mounting rod, and the mounting rod passing through the interior of the mounting frame; A sliding button is slidably mounted on one side of the outer surface of the machine body. One end of the sliding button is provided with a connecting bracket, and one end of the connecting bracket is fixedly connected to the outer surface of the mounting bracket. Locking components are provided on both sides of the outer surface of the sliding button, and the sliding button is locked by sliding up and down through the locking components.

[0006] Preferably, a fixed frame is fixedly installed inside the body, and a guide rod is fixedly installed inside the fixed frame. A guide frame is fixedly installed on the outer surface of the rear end of the mounting frame, and the guide frame is sleeved on the outer surface of the guide rod. A third spring is sleeved on the outer surface of the guide rod above the guide frame. When the mounting frame moves upward, it will drive the guide frame to slide upward along the guide rod, compressing the third spring. After the thread passes through, the sliding button is released, and the third spring will drive the mounting frame to return to its downward position.

[0007] Preferably, a sliding groove is provided on one outer surface of the machine body, and the sliding button is slidably connected to the machine body through the sliding groove. The mounting bracket is pushed upward by the sliding button so that the pressure rollers on both sides are higher than the sensing rollers.

[0008] Preferably, a second spring is installed inside the connecting frame at one end of the slide button, and one end of the second spring is fixedly connected to one end of the slide button, so that the slide button is pushed outward to reset by the second spring.

[0009] Preferably, the locking assembly includes locking pins inserted into the outer surfaces of both sides of the slide button. The inner walls of the slide groove have locking grooves at one end of the locking pins, and the inner end of the locking pin is inclined. The slide button has a first spring at the other end of the locking pin, and one end of the first spring is fixedly connected to the locking pin. When the slide button is pressed inward, the locking pins on both sides will be pushed inward along the inclined end and retract, compressing the first spring and causing one end of the locking pin to disengage from the locking groove on the inner wall of the slide groove, thus releasing the limitation on the slide button.

[0010] (III) Beneficial Effects Compared with the prior art, this utility model provides an air-coated yarn tension tester, which has the following beneficial effects: The pressure roller can be adjusted up and down by setting a sliding knob. The sliding knob is equipped with a locking pin structure on both sides, which can lock the sliding knob when not in use. This prevents the sliding knob from being moved by external force during carrying, reduces wear on the mounting frame, and increases the service life of the tester. Attached Figure Description

[0013] 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.

[0014] Please see Figure 1-3 The present invention provides the following technical solution: an air-coated yarn tension tester, comprising a body 1, a mounting frame 3 at the top of the body 1, two sets of pressure rollers 31 mounted on the outer surface of the top of the mounting frame 3, a mounting rod 32 mounted at the center of the top of the body 1, a sensing wheel 33 mounted on the outer surface of the top of the mounting rod 32, and the mounting rod 32 passing through the interior of the mounting frame 3; In this embodiment, a fixed frame 34 is fixedly installed inside the body 1, and a guide rod 35 is fixedly installed inside the fixed frame 34. A guide frame 37 is fixedly installed on the outer surface of the rear end of the mounting frame 3, and the guide frame 37 is sleeved on the outer surface of the guide rod 35. A third spring 36 is sleeved on the outer surface of the guide rod 35 above the guide frame 37. When the mounting frame 3 moves upward, it will drive the guide frame 37 to slide upward along the guide rod 35, compressing the third spring 36. After the wire passes through, the sliding button 2 is released, and the third spring 36 will drive the mounting frame 3 to return to its original position downward. In this embodiment, the sliding button 2 is slidably installed on one side of the outer surface of the body 1. One end of the sliding button 2 is provided with a connecting frame 23, and one end of the connecting frame 23 is fixedly connected to the outer surface of the mounting frame 3. Locking components are provided on both sides of the outer surface of the sliding button 2, and the sliding button 2 is locked up and down by the locking components.

[0015] The outer surface of one side of the body 1 is provided with a sliding groove 11, and the sliding button 2 is slidably connected to the body 1 through the sliding groove 11. The mounting bracket 3 is pushed upward by the sliding button 2, so that the pressure rollers 31 on both sides are higher than the sensing rollers 33. A second spring 24 is installed inside the connecting bracket 23 at one end of the sliding button 2, and one end of the second spring 24 is fixedly connected to one end of the sliding button 2. The sliding button 2 is pushed outward to reset by the second spring 24.

[0016] In this embodiment, it should also be noted that the locking assembly includes locking pins 21 inserted into the outer surfaces of both sides of the slide button 2. Locking grooves are provided on both sides of the inner wall of the slide groove 11 at one end of the locking pins 21, and the inner end of the locking pins 21 is inclined. A first spring 22 is provided inside the slide button 2 at the other end of the locking pins 21, and one end of the first spring 22 is fixedly connected to the locking pins 21. When the slide button 2 is pressed inward, the locking pins 21 on both sides will be pushed inward along the inclined end and retract, squeezing the first spring 22, so that one end of the locking pins 21 disengages from the locking groove on the inner wall of the slide groove 11, thereby releasing the limitation on the slide button 2.

[0017] The working principle of this embodiment is as follows: During testing, the mounting bracket 3 is pushed upward by the sliding button 2, so that the pressure rollers 31 on both sides are higher than the sensing rollers 33. Then, the measuring wire passes through from below the pressure rollers 31 and above the sensing rollers 33. As the mounting bracket 3 moves upward, it will drive the guide bracket 37 to slide upward along the guide rod 35, compressing the third spring 36. After the wire passes through, the sliding button 2 is released, and the third spring 36 will drive the mounting bracket 3 to return to its original position downward, pressing the two ends of the wire downward, so that the middle of the wire presses the sensing roller 33, thereby testing the tension of the wire. When the slider 2 slides along the slide groove 11, first press the slider 2 inward, and the locking pins 21 on both sides will be pushed inward along one end of the inclined surface to retract, compressing the first spring 22, so that one end of the locking pin 21 disengages from the locking groove on the inner wall of the slide groove 11, releasing the limitation on the slider 2. Then slide the slider 2 along the slide groove 11. After use, the slider 2 is pushed outward by the second spring 24 to reset, so that one end of the locking pin 21 corresponds to the locking groove. The first spring pushes the locking pin 21 outward to insert it into the locking groove for limitation and fixation.
