Description

Technical Field

[0001] This utility model relates to the field of textile testing equipment technology, and in particular to a testing device for core-spun yarn production. Background Technology

[0002] Core-spun yarn is a composite yarn structure consisting of a core yarn and an outer layer of fibers. It typically uses high-strength fibers (such as polyester and spandex) as the core yarn, wrapped with short fibers (such as cotton and viscose) through twisting or covering processes. Due to its advantages of high strength, good elasticity, and soft hand feel, it is widely used in clothing, home textiles, and functional textiles. With the continuous improvement of market demand, the requirements for the quality of core-spun yarn products are also increasing, especially in terms of abrasion resistance, strength stability, and yarn uniformity.

[0003] Currently, quality inspection in the production of core-spun yarn relies heavily on manual sampling or single-function testing equipment, lacking integrated and automated testing systems. For example, when evaluating the abrasion resistance of core-spun yarn, samples typically need to be sent to a laboratory for simulated testing, making online rapid testing impossible. Furthermore, the measurement of yarn tension and offset lacks real-time feedback and adaptive adjustment mechanisms, resulting in low testing efficiency and significant errors in the results.

[0004] Therefore, it is necessary to design a testing device for core-spun yarn production to solve the above-mentioned technical problems. Utility Model Content

[0005] In order to overcome the shortcomings of existing technologies that rely heavily on manual sampling or single-function testing equipment for core-spun yarn quality inspection and lack integrated and automated testing systems, this utility model provides a testing device for core-spun yarn production.

[0006] Technical solution: A testing device for core-spun yarn production includes a mounting plate, a winding assembly, a limiting assembly, a polishing test assembly, a pressure test assembly, and a controller. The mounting plate has winding assemblies at its front and rear ends, and limiting assemblies are symmetrically arranged on the front and rear sides of the mounting plate, with the limiting assemblies located inside the winding assemblies. The polishing test assemblies are symmetrically arranged on the front and rear sides of the mounting plate, with the polishing test assemblies located inside the limiting assemblies. A pressure test assembly is located in the middle of the top of the mounting plate, inside the polishing test assemblies. A controller is installed on the front side of the top of the mounting plate.

[0007] In one embodiment, the winding assembly includes a first motor and a mounting rod. The first motor with an upward output axis is mounted on the rear top side of the mounting plate, and the mounting rod is fixedly connected to its output shaft. Another mounting rod is fixedly connected to the front top side of the mounting plate. The first motor is electrically connected to the controller.

[0008] In one embodiment, the limiting component includes a positioning ring, a limiting block, and a first spring. Multiple limiting blocks are symmetrically distributed along the center of the outer ring of the positioning ring. The limiting blocks are slidably connected to the positioning ring, and the first spring is provided between the lower part of the limiting block and the positioning ring.

[0009] In one embodiment, the grinding test assembly includes a mounting block, a limiting plate, a sliding block, a second motor, a grinding wheel, and a second spring. Each set of grinding test assemblies is symmetrically distributed on the left and right sides of the mounting plate. Mounting blocks are symmetrically fixedly connected to the top left and right sides of the mounting plate. A limiting plate is slidably connected to the side of the mounting blocks that are close to each other. A first groove is opened on the front and rear sides of the top of the limiting plate. A sliding block is slidably connected to the first groove of the limiting plate. A second motor with its output shaft pointing downwards and penetrating through the bottom is mounted on the top of the sliding block. A grinding wheel is fixedly connected to its output shaft. A second groove is opened in the middle of the upper and lower sides of the limiting plate. The upper and lower ends of the grinding wheel are slidably connected to the second groove. A second spring is provided between the mounting block and the limiting plate. The second motor is electrically connected to the controller.

[0010] In one embodiment, the pressure testing assembly includes a third motor, a sector block, and a pressure sensor. The third motor is symmetrically mounted on the left and right sides of the top of the mounting plate, with a sector block fixedly connected to its output shaft. The two sector blocks are arranged in a sector shape on the side closest to each other and are embedded with a pressure sensor. Both the third motor and the pressure sensor are electrically connected to the controller.

[0011] In one embodiment, the device also includes a detection ring and a laser detector. Detection rings are symmetrically arranged on both sides of the pressure testing component on the top of the mounting plate. Multiple laser detectors are evenly distributed in the circumferential direction inside each detection ring. At the same time, a detection ring is also provided on the outside of the limiting component. The laser detectors are electrically connected to the controller.

[0012] Beneficial effects: 1. This utility model achieves efficient and accurate comprehensive testing of various performance indicators of core-spun yarn through winding, polishing, pressure testing, and condition monitoring systems; this device integrates multiple testing steps on one platform, from automatic winding of core-spun yarn to surface wear testing to compressive strength assessment, and finally to real-time monitoring with a laser detector. The whole process is highly automated, reducing errors caused by manual intervention and improving the accuracy and reliability of the test results.

[0013] 2. This utility model achieves the effect of maintaining appropriate tension and preventing deviation or uneven winding during the winding process by automatically adjusting the position of the positioning ring and the limiting block in the limiting component according to the actual diameter of the core-spun yarn. This adaptive adjustment mechanism can dynamically adjust the position of the limiting block according to the actual size of the core-spun yarn, ensuring that the yarn always maintains the best tension state during winding, avoiding yarn quality problems caused by uneven tension, and improving the quality consistency of the final product.

[0014] 3. This utility model achieves flexible adaptation to testing requirements of different diameters or positions by using a sliding block in the grinding test assembly to slide left and right along the slide groove, thereby driving the grinding wheel and the second motor to move laterally as a whole. This design allows the operator to precisely adjust the position of the grinding wheel according to specific needs to simulate wear conditions under different usage environments, thereby more comprehensively evaluating the abrasion resistance of the core-spun yarn. At the same time, combined with the data analysis function of the laser detector, the detection accuracy of changes in yarn surface quality is further improved. Attached Figure Description

Detailed Implementation

[0020] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings.

[0021] Example: A testing device for core-spun yarn production, such as... Figure 1 and Figure 4 As shown, the assembly includes a mounting plate 1, a winding assembly 2, a limiting assembly 3, a grinding test assembly 4, a pressure test assembly 5, and a controller 7. The winding assembly 2 is located at the front and rear ends of the top of the mounting plate 1. The limiting assembly 3 is symmetrically located on the front and rear sides of the top of the mounting plate 1, and the limiting assembly 3 is located inside the winding assembly 2. The grinding test assembly 4 is symmetrically located on the front and rear sides of the top of the mounting plate 1, and the grinding test assembly 4 is located inside the limiting assembly 3. The pressure test assembly 5 is located in the middle of the top of the mounting plate 1, and it is located inside the grinding test assembly 4. The controller 7 is installed on the front side of the top of the mounting plate 1.

[0022] like Figure 1 , Figure 2 and Figure 4 As shown, the winding assembly 2 includes a first motor 21 and a mounting rod 22. The first motor 21 with an upward output axis is mounted on the top rear side of the mounting plate 1, and the mounting rod 22 is connected to its output shaft by welding. Another mounting rod 22 is connected to the top front side of the mounting plate 1 by bolts. The first motor 21 is electrically connected to the controller 7. The limiting assembly 3 includes a positioning ring 30, a limiting block 31 and a first spring 32. Multiple limiting blocks 31 are symmetrically distributed along the center on the outer ring of the positioning ring 30. The limiting blocks 31 are slidably connected to the positioning ring 30. The first spring 32 is provided between the lower part of the limiting block 31 and the positioning ring 30.

[0023] When the operator prepares to use the testing device for core-spun yarn production, the core-spun yarn to be tested must first be installed on the winding assembly 2. The operator first fixes one end of the core-spun yarn to the front mounting rod 22, and then passes the other end through the limiting assembly 3 and fixes it to the rear mounting rod 22. The core-spun yarn is then passed between the limiting blocks 31 in the center of the positioning ring 30. Then, the first motor 21 is started by the controller 7, which drives the mounting rod 22 to rotate and begin winding the core-spun yarn. During the winding process, the core-spun yarn will move accordingly. The first spring 32 can better clamp the core-spun yarn so that it is not easy to shift, so as to maintain appropriate tension and prevent the occurrence of deviation or uneven winding.

[0024] like Figure 1 , Figure 3 and Figure 4 As shown, the grinding test assembly 4 includes a mounting block 40, a limiting plate 41, a sliding block 42, a second motor 43, a grinding wheel 44, and a second spring 45. Each set of grinding test assemblies 4 is symmetrically distributed on the left and right sides of the mounting plate 1. The mounting blocks 40 are symmetrically connected to the top left and right sides of the mounting plate 1 by bolts. The mounting blocks 40 are slidably connected to the limiting plate 41 on the side that is close to each other. The limiting plate 41 has a first groove on the front and rear sides of the top of the limiting plate 41. The sliding block 42 is slidably connected to the first groove of the limiting plate 41. The second motor 43 with its output shaft pointing downward and penetrating through the bottom of the sliding block 42 is installed on the top of the sliding block 42. The grinding wheel 44 is connected to its output shaft by bolts. The limiting plate 41 has a second groove in the middle of the upper and lower sides. The upper and lower ends of the grinding wheel 44 are slidably guided by the second groove. The second spring 45 is provided between the mounting block 40 and the limiting plate 41 to provide buffer and maintain stable grinding pressure. The second motor 43 is electrically connected to the controller 7.

[0025] As the core-spun yarn begins to wind up, the system enters the abrasion test phase. At this time, the operator can set the abrasion speed via controller 7 and adjust the spacing between the abrasion wheels 44 according to the diameter of the core-spun yarn. By pushing the sliding block 42 along the slide groove, the wheels slide left and right, thereby moving the abrasion wheels 44 and the second motor 43 laterally as a whole. After moving to a suitable position, they are fixed with bolts to adapt to testing requirements for different diameters or positions. Upon receiving a command, controller 7 starts the second motor 43, causing the abrasion wheels 44 to rotate and contact the surface of the core-spun yarn, simulating the wear conditions in actual use. This process not only effectively detects the abrasion resistance of the core-spun yarn but also allows for simultaneous analysis of its surface quality based on data collected by the laser detector 61.

[0026] like Figure 1 , Figure 3 and Figure 4 As shown, the pressure testing assembly 5 includes a third motor 50, a sector block 51, and a pressure sensor 52. The third motor 50 is symmetrically mounted on the left and right sides of the top of the mounting plate 1, with the output shaft connected to the sector block 51 by a snap-fit. The two sector blocks 51 are arranged in a sector shape on the side that is close to each other, and the pressure sensor 52 is embedded therein. Both the third motor 50 and the pressure sensor 52 are electrically connected to the controller 7.

[0027] Through the aforementioned series of automated operations, from core-spun yarn winding, polishing tests, pressure tests to final condition monitoring, the entire testing process efficiently and accurately completes a comprehensive evaluation of its various performance indicators, ensuring that product quality meets relevant standards. This integrated design not only significantly improves work efficiency but also effectively reduces errors caused by human operation, thereby greatly enhancing the accuracy and reliability of the test results.

[0028] After the polishing test is completed, the system enters the pressure test phase. At this time, the third motor 50 starts, driving the fan-shaped blocks 51 on both sides to rotate inward and gradually approach the core-spun yarn. As the fan-shaped blocks 51 approach, the pressure sensors 52 embedded on them begin to measure the pressure value applied to the core-spun yarn. By adjusting the rotation angle and running speed of the third motor 50, the pressure can be precisely controlled, thereby comprehensively evaluating the strength and stability of the core-spun yarn under pressure.

[0029] like Figure 1 , Figure 2 and Figure 4 As shown, it also includes a detection ring 6 and a laser detector 61. The top of the mounting plate 1 is symmetrically provided with detection rings 6 on both sides of the pressure testing component 5. Each detection ring 6 has multiple laser detectors 61 evenly distributed in the circumferential direction. At the same time, a detection ring 6 is also provided on the outside of the limiting component 3 to assist in detecting the yarn state. The laser detector 61 is electrically connected to the controller 7.

[0030] Throughout the entire testing process, the laser detectors 61 arranged in various parts of the device operate continuously, monitoring the state of the core-spun yarn in real time, including key indicators such as its diameter change, surface flatness, and whether there is a risk of breakage. All collected data are transmitted to the controller 7 for comprehensive analysis, providing a scientific basis for subsequent quality assessment.
