Abstract
Description
Technical Field
[0001] This utility model relates to the field of electronic yarn detection, and in particular to an electronic yarn tension detection device. Background Technology
[0002] Key performance characteristics of electronic yarn include the smoothness of yarn unwinding during weaving, the stability of air pressure during weaving, and the stability of yarn flight (also referring to flight stability, indicators of which include spread area, blown weight, and flight distance) during yarn feeding. These performance indicators largely depend on the magnitude and fluctuation of yarn tension. Therefore, controlling the magnitude and stability of yarn tension becomes essential for meeting customer needs and controlling product quality. Controlling tension requires appropriate testing methods, and the test results must be quantifiable, with minimal impact from different personnel's operations. However, current technology has not yet developed instruments or methods for directly testing the tension of electronic yarn. Existing indirect methods for testing electronic yarn tension mainly include stiffness and blown weight. Stiffness testing involves taking several 1-meter-long strands of yarn, folding them in half, twisting them manually a few times, placing them on a measuring stand, and measuring the straight-line distance between the two drooping ends. The measured length in millimeters is the stiffness. Airflow testing involves placing a tube of yarn on a stand, passing the yarn through a nozzle, and blowing air from the nozzle at a fixed pressure. The yarn's flight capability is evaluated based on the weight and area of yarn blown out per unit time. Both methods require manual operation, leading to significant variations between operators, making it difficult to quantitatively analyze the tension of electronic yarns, and resulting in relatively low efficiency.
[0003] The technical problem that this invention needs to solve is: how to quantitatively detect and analyze the tension and stability of electronic yarn. Utility Model Content
[0004] The main purpose of this invention is to provide an electronic yarn tension detection device. By setting up a tension detection unit and a yarn length detection unit, the device samples electronic yarn products at different lengths according to the yarn length, and adjusts the distance between the support and the tension detection unit to keep the environmental parameters consistent each time the electronic yarn is detected. This allows the device to obtain the tension fluctuation range and average tension of the electronic yarn when it is wound up to a certain length, thereby achieving quantitative detection and analysis of the electronic yarn.
[0005] To achieve the above objectives, the technical solution adopted in this application is as follows:
[0006] An electronic yarn tension detection device includes a bracket, a tension detection unit, and a yarn length detection unit; the bracket is provided with a hanging strip for suspending a yarn bobbin; the bracket is provided with an adjustment module for adjusting the distance between the hanging strip and the tension detection unit; the yarn length detection unit is disposed on one side of the bracket; the tension detection unit is placed on the yarn length detection unit and connected to one end of the adjustment module;
[0007] The yarn length detection unit is used to wind up the yarn on the yarn bobbin and measure the length of the wound yarn.
[0008] The tension detection unit is used to measure the tension of the yarn during the yarn winding process of the yarn length detection unit.
[0009] Preferably, it further includes a control unit; the control unit is communicatively connected to the tension detection unit and the yarn length detection unit respectively; the control unit is used to receive and record data from the tension detection unit and the yarn length detection unit.
[0010] Preferably, the adjustment module includes a crossbar and a slider; the slider is slidably connected to the crossbar; the slider is connected to the bottom of the bracket; the slider is provided with a limiting member; the limiting member is used to restrict the movement of the slider on the crossbar.
[0011] Preferably, the tension detection unit includes a mounting base and a tension sensor; the mounting base is connected to the side of the yarn length detection unit; the tension sensor is connected to the mounting base; and the end of the crossbar is connected to the side of the bottom of the mounting base.
[0012] Preferably, the crossbar is provided with a scale for observing the distance data between the support and the tension detection unit.
[0013] Preferably, the side of the mounting base is U-shaped; the mounting base is embedded in the side of the yarn length detection unit; and the tension detection unit is connected to the free end of the mounting base.
[0014] Preferably, the yarn length detection unit is provided with a yarn guide rod and a take-up roller; the tension detection unit is located between the yarn guide rod and the take-up roller.
[0015] Compared with existing technologies, this solution has the following advantages:
[0016] The tension detection device in this case adjusts and fixes the distance between the support and the tension detection unit through an adjustment module. This distance is used to measure the tension of electronic yarn of the same model. Moreover, the sampling length of electronic yarn of different lengths is determined according to a percentage and sampled by the yarn length detection unit. During the sampling process, the tension detection unit detects the tension of the electronic yarn to obtain the average tension and stability of the electronic yarn. Since the same parameters are used to measure different electronic yarns, there is no human intervention, and the tension of different electronic yarns can be compared to detect the tension of different electronic yarns.
[0017] Secondly, since the distance between the sand cylinder and the tension detection unit is not the same, the same electronic yarn will also obtain different tension values. Therefore, it is necessary to adjust the distance between the bracket and the tension detection unit multiple times by adjusting the adjustment module based on the market feedback on the use of electronic yarn, so as to obtain the tension benchmark value of electronic yarn. This will enable quantitative measurement of the tension of electronic yarn, provide reference data analysis for the development of electronic yarn, and benefit the development of new products.

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of this application implemented as described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.
[0023] Example 1
[0024] refer to Figure 1-3An electronic yarn tension detection device includes a bracket 1, a tension detection unit 2, and a yarn length detection unit 3; the bracket 1 is provided with a hanging strip 11 for suspending the yarn bobbin; the bracket 1 is provided with an adjustment module 4 for adjusting the distance between the hanging strip 11 and the tension detection unit 2; the yarn length detection unit 3 is disposed on one side of the bracket 1; the tension detection unit 2 is placed on the yarn length detection unit 3 and connected to one end of the adjustment module 4;
[0025] The yarn length detection unit 3 is used to wind up the yarn on the yarn bobbin and measure the length of the yarn winding.
[0026] The tension detection unit 2 is used to measure the tension of the yarn during the yarn winding process of the yarn length detection unit 3.
[0027] In this embodiment, the tension detection device is mainly used in the development stage and finished product testing stage of electronic yarn products. It measures the tension and stability of the electronic yarn. In the initial stage, the distance between the support 1 and the tension detection unit 2 is adjusted using the adjustment module 4. Based on customer feedback and multiple trials, the optimal distance between the support 1 and the tension detection unit 2 is determined, thereby establishing the distance and angle between the electronic yarn and the tension detection unit 2. This ensures that the position of the electronic yarn remains constant each time. Furthermore, since electronic yarn products have different length specifications, the tension of the sample is measured by quantitative sampling using the yarn length detection unit 3. For example, 5% of the entire roll of yarn is used as the sample. This method ensures that the parameters and environmental conditions are the same when measuring different electronic yarns. By comparing the obtained tension data with the evaluation benchmark, the tension of the measured electronic yarn is obtained, thereby achieving quantitative detection and analysis of the electronic yarn, reducing the influence of human intervention, and improving the accuracy of the detection.
[0028] The specific working process of the tension detection device is as follows: The operator adjusts the distance between the bracket 1 and the war drum detection unit according to the requirements through the adjustment module 4. After the adjustment is completed, the yarn bobbin is placed on the hanging strip 11. The electronic yarn on the yarn bobbin is passed through the thread guide rod 31 of the yarn length detection unit 3 and then wound around the tension detection unit 2. The free end of the electronic yarn is then fixed on the yarn length detection unit 3. The yarn length detection unit 3 is started, and the yarn length detection unit 3 winds up the electronic yarn of the required length. During the winding process, the tension detection unit 2 records the tension of the electronic yarn in real time. Finally, the average tension is calculated based on the maximum and minimum tension values. Moreover, the stability of the tension, that is, the fluctuation range, can also be clearly known based on the maximum and minimum tension values.
[0029] It should be noted that the yarn length detection unit 3 is a yarn length measuring instrument in the existing technology. The evaluation criteria are obtained through customer feedback and experiments. The tension and stability of the electronic yarn can be directly observed based on the measured values. Since the measurement is carried out under the same conditions, different electronic yarns can be compared with each other, which is of great reference value for product development.
[0030] Preferably, it also includes a control unit; the control unit is communicatively connected to the tension detection unit 2 and the yarn length detection unit 3 respectively; the control unit is used to receive and record the data from the tension detection unit 2 and the yarn length detection unit 3.
[0031] In this embodiment, the control unit is a PLC (not shown in the figure). The control unit is communicatively connected to the yarn length detection unit 3, and can control the start / stop, length, and rotation speed of the yarn length detection unit 3; the control unit is also communicatively connected to the tension detection unit 2, and can control the detection interval and number of times of the tension detection unit 2. Through the control unit, tension changes can be detected quickly, accurately, and stably. Furthermore, by inputting a pre-written program into the control unit, the data from the yarn length detection unit 3 and the tension detection unit 2 can be converted into tension values. The control unit is connected to a computer, transmitting the data to the computer, which then generates a tension detection report.
[0032] Preferably, the adjustment module 4 includes a crossbar 41 and a slider 42; the slider 42 is slidably connected to the crossbar 41; the slider 42 is connected to the bottom of the bracket 1; the slider 42 is provided with a limiting member 43; the limiting member 43 is used to restrict the movement of the slider 42 on the crossbar 41.
[0033] In this embodiment, the limiting member 43 is a screw, and the limiting member 43 is threadedly connected to the sliding member 42. The bracket 1 is slidably connected to the crossbar 41 through the sliding member 42. The operator pushes the bracket 1, thereby moving the bracket 1 on the crossbar 41 to adjust the distance between the bracket 1 and the tension detection unit 2. After the adjustment is completed, the screw is tightened to restrict the movement of the sliding member 42 on the crossbar 41, so that the bracket 1 can maintain the distance between itself and the tension detection unit 2.
[0034] Preferably, the tension detection unit 2 includes a mounting base 21 and a tension sensor 22; the mounting base 21 is connected to the side of the yarn length detection unit 3; the tension sensor 22 is connected to the mounting base 21; and the end of the crossbar 41 is connected to the side of the bottom of the mounting base 21.
[0035] In this embodiment, since the yarn length detection unit 3 is an existing product, a mounting base 21 is used to fix it to the side of the yarn length detection unit 3, making it easy to form a whole with the bracket 1, tension detection unit 2, and yarn length detection unit 3. Then, the tension sensor 22 is installed on the mounting base 21, eliminating the need for extensive modifications to the yarn length detection unit 3 and reducing manufacturing costs.
[0036] Preferably, the crossbar 41 is provided with a scale for observing the distance data between the support 1 and the tension detection unit 2. This facilitates the staff in determining the distance between the support 1 and the tension detection unit 2.
[0037] Preferably, the side of the mounting base 21 is U-shaped; the mounting base 21 is embedded in the side of the yarn length detection unit 3; and the tension detection unit 2 is connected to the free end of the mounting base 21.
[0038] In this embodiment, the mounting base 21 is U-shaped, and the U-shaped notch is inserted into the side of the yarn length detection unit 3, thereby fixing the mounting base 21 to the side of the yarn length detection unit 3 without damaging the structure of the yarn length detection unit 3, and making it easy to disassemble and assemble.
[0039] Preferably, the yarn length detection unit 3 is provided with a yarn guide bar 31 and a take-up roller 32; the tension detection unit 2 is located between the yarn guide bar 31 and the take-up roller 32.
[0040] In this embodiment, the yarn length detection unit 3 removes the original tension device. After the yarn bobbin is placed on the hanging strip 11, the free end of the electronic yarn passes through the thread rod 31, then around the tension detection unit 2, and finally connects to the take-up roller. The motor drives the take-up roller to rotate, thereby causing the electronic yarn to be wound onto the take-up roller. The tension detection unit 2 measures the tension of the electronic yarn during this process.
