Abstract
Description
Technical Field
[0001] This utility model relates to a detection device, specifically a fabric pilling and fuzzing detection device, belonging to the technical field of fabric detection equipment. Background Technology
[0002] Fabrics are flexible materials made from fibers through spinning, weaving, and nonwoven processes. They are widely used in clothing, home textiles, and industrial textiles. Fabric pilling testing is an important test to assess the phenomenon of surface fiber breakage and entanglement forming pills during friction, washing, or wearing. Under external friction, the surface fibers of a fabric break due to mechanical force, and the broken fiber ends become entangled to form pills. The test accelerates this process by simulating real-world usage scenarios (such as clothing friction and washing).
[0003] Currently, existing fabric pilling detection devices often encounter problems during use. If the fabric to be tested is not securely positioned, it may rotate with the nylon brush, affecting both the testing results and the device's efficiency. To address these issues, we provide a fabric pilling detection device that solves these problems. Utility Model Content
[0004] To address the aforementioned problems, this utility model provides a device for detecting pilling and fuzzing of fabrics. The specific technical solution is as follows:
[0005] A fabric pilling and fuzzing detection device includes a detection platform, a mounting shell, and an assembly shell.

A spring is provided on the outer side of each limiting rod, and the bottom end of the spring is connected to the top end of the limiting cylinder. A compression ring is provided at the bottom end of each of the limiting cylinders. The upper surface of the detection platform is provided with multiple sets of placement plates. A first magnet is embedded in the upper surface of each placement plate. A positioning ring is movably arranged on the upper surface of each placement plate. A second magnet is embedded inside the positioning ring, and the second magnet is magnetically attracted to the first magnet.
[0006] Preferably, the testing platform has two sets of rotating doors inside, and a control box is provided on one side of the testing platform.
[0007] Preferably, a guide frame is provided on the back of the testing platform, a threaded rod is rotatably provided inside the guide frame, a No. 1 motor is provided on one side of the guide frame, and the output end of the No. 1 motor is connected to one end of the threaded rod.
[0008] Preferably, a support frame is movably sleeved on the outer side of the guide frame, the threaded rod is threaded through the interior of the support frame, an electric push rod is provided at the top of the support frame, a pressure sensor is provided at the output end of the electric push rod, the pressure sensor is provided at the top of the mounting shell, and two guide rods are provided on the upper surface of the mounting shell on both sides of the pressure sensor, and the two sets of guide rods movably pass through the interior of the support frame.
[0009] Preferably, a second motor is installed inside the mounting housing, and a nylon brush disc is installed at the output end of the second motor, wherein the outer diameter of the nylon brush disc is smaller than the inner diameter of the extrusion ring.
[0010] Preferably, the inner side of the support frame is provided with two sets of support plates, and the two sets of support plates are rotatably provided with mounting plates, and the upper surface of the mounting plates is provided with cameras.
[0011] Preferably, the interior of the testing platform has multiple through holes, the assembly shell is disposed inside the testing platform and is located below the through holes, the interior of the assembly shell has a filter screen, and the interior of the assembly shell has three sets of exhaust fans.
[0012] Compared with the prior art, the present invention has the following beneficial effects:
[0013] 1. In this utility model, by setting components such as a squeezing ring and a positioning ring, after the first magnet (placement plate) and the second magnet (positioning ring) are magnetically attracted together, the fabric that needs to be tested for pilling can be quickly fixed and displacement can be avoided. During the process of the electric push rod pushing the squeezing ring down, after the squeezing ring contacts the upper surface of the positioning ring, the limiting cylinder can move upward outside the limiting rod. Utilizing the elastic action of the spring outside the limiting rod, the positioning ring can be squeezed, and the fabric that needs to be tested for pilling can be squeezed and positioned again, which effectively improves the test effect of fabric pilling and the working efficiency of the testing device.
[0014] 2. In this utility model, by setting up components such as filters, during the operation of the three sets of exhaust fans inside the assembly shell, external air can enter the assembly shell through the through holes. By using the exhaust fans and filters in conjunction, fibers that fall off the upper surface of the test platform can be sucked into the assembly shell through the through holes. The filters are used to filter and block the sucked fibers, keeping the test interface clean and preventing secondary entanglement. Attached Figure Description

Detailed Implementation
[0022] The present invention will now be further described with reference to the accompanying drawings.
[0023] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 A device for detecting pilling and fuzzing of fabrics;
[0024] The system includes a testing platform 1, a mounting shell 11, and an assembly shell 26. The bottom of the mounting shell 11 is provided with four sets of limiting rods 14. Limiting cylinders 15 are movably sleeved on the outer side of the limiting rods 14. Springs 16 are provided on the outer side of the limiting rods 14, and the bottom end of the springs 16 is connected to the top end of the limiting cylinders 15. Compression rings 17 are provided at the bottom ends of the multiple sets of limiting cylinders 15. Multiple placement plates 21 are provided on the upper surface of the testing platform 1. A first magnet 22 is embedded in the upper surface of the placement plate 21. A positioning ring 23 is movably provided on the upper surface of the placement plate 21. A second magnet 24 is embedded in the interior of the positioning ring 23, and the second magnet 24 and the first magnet 22 are magnetically attracted to each other.
[0025] The placement plate 21 is used to support the fabric that needs to be tested for pilling and fuzzing. It can be magnetically attracted by magnet 22 and magnet 24. After magnet 22 (placement plate 21) and magnet 24 (positioning ring 23) are magnetically attracted, the fabric that needs to be tested for pilling and fuzzing can be quickly fixed and displacement can be avoided. During the process of the electric push rod 8 pushing the squeezing ring 17 down, since the squeezing ring 17 is lower than the nylon brush plate 13, after the squeezing ring 17 contacts the upper surface of the positioning ring 23 (both the squeezing ring 17 and the positioning ring 23 are circular rings of the same size), the limiting cylinder 15 can move up outside the limiting rod 14. Using the elastic action of the spring 16 outside the limiting rod 14, the positioning ring 23 can be squeezed, and the fabric that needs to be tested for pilling and fuzzing can be squeezed and positioned again, which effectively improves the test effect of fabric pilling and fuzzing and the working efficiency of the testing device.
[0026] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 A device for detecting pilling and fuzzing of fabrics;
[0027] The testing platform 1 has two sets of rotating opening and closing doors 2 inside. A control box 3 is located on one side of the testing platform 1, and a guide frame 4 is located on the back of the testing platform 1. A threaded rod 5 is rotatably installed inside the guide frame 4. A No. 1 motor 6 is located on one side of the guide frame 4, and the output end of the No. 1 motor 6 is connected to one end of the threaded rod 5. A support frame 7 is movably fitted on the outside of the guide frame 4. The threaded rod 5 is threaded through the interior of the support frame 7. An electric push rod 8 is located at the top of the support frame 7. A pressure sensor 9 is located at the output end of the electric push rod 8. The pressure sensor 9 is located at the top of the mounting shell 11. Two guide rods 10 are arranged on both sides of the upper surface of the mounting shell 11 relative to the pressure sensor 9. The two sets of guide rods 10 movably pass through the interior of the support frame 7.
[0028] The testing platform 1 is the main component of the fabric pilling and fuzzing detection device, which provides installation support for the working components. The opening and closing door 2 facilitates the disassembly and assembly of the assembly shell 26 and filter screen 27 inside the testing platform 1. The guide frame 4 is bolted to the back of the testing platform 1. The support frame 7 is movably sleeved on the outside of the guide frame 4, and the threaded rod 5 is threaded through the inside of the support frame 7. During the operation of the first motor 6, the threaded rod 5 can drive the support frame 7 to move laterally, realizing a reciprocating friction path (stroke programmable control). This allows for flexible adjustment of the position of the nylon brush disc 13, enabling the nylon brush disc 13 to move alternately on the five sets of placement plates 21.
[0029] During operation, the electric push rod 8 at the top of the support frame 7 works in conjunction with the pressure sensor 9 to precisely control the downward pressure of the nylon brush 13 on the fabric (adjustable range is usually 5-20 kPa). The two guide rods 10 ensure that the pressure is applied in a vertical direction to avoid uneven wear, thus enabling real-time pressure feedback adjustment to simulate different wearing scenarios (such as high pressure for frequent elbow friction and low pressure for underwear).
[0030] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 A device for detecting pilling and fuzzing of fabrics;
[0031] The mounting housing 11 is equipped with a second motor 12. The output end of the second motor 12 is equipped with a nylon brush disc 13. The outer diameter of the nylon brush disc 13 is smaller than the inner diameter of the compression ring 17. The inner side of the support frame 7 is equipped with two sets of support plates 18. The two sets of support plates 18 are rotatably equipped with mounting plates 19. The upper surface of the mounting plate 19 is equipped with a camera 20.
[0032] Mounting housing 11 provides mounting space for motor 12. When motor 12 is running, it can drive nylon brush disk 13 to rotate and perform friction on the sample placed on the upper surface of the placement plate 21 (speed adjustable, such as 100-500 rpm) to simulate unidirectional or multidirectional friction. The diameter of nylon brush disk 13 is smaller than that of extrusion ring 17 to ensure that friction only acts on the central area of the sample and avoid edge effects.
[0033] Mounting plate 19 is rotatably mounted between two sets of support plates 18. By using a nut to screw onto a threaded rod on one side of mounting plate 19, the angle of mounting plate 19 can be adjusted and positioned. Camera 20 is a high-resolution camera used to photograph the fabric surface (e.g., once every 30°), capturing the microscopic morphology of the fabric surface. The photographed images are transmitted to control box 3 for image processing. Combined with AI algorithms (e.g., OpenCV contour detection), the density and area ratio of lint balls are calculated in real time, which can effectively reduce human subjective error and can be integrated into the production line for online inspection.
[0034] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 A device for detecting pilling and fuzzing of fabrics; the inside of the detection platform 1 is provided with multiple sets of through holes 25, the assembly shell 26 is disposed inside the detection platform 1 and is located below the through holes 25, the inside of the assembly shell 26 is provided with a filter screen 27, and the inside of the assembly shell 26 is provided with three sets of exhaust fans 28.
[0035] The test platform 1 is formed through the through hole 25, and the assembly shell 26 is located below the through hole 25. During the operation of the three sets of exhaust fans 28 inside the assembly shell 26, external air can enter the assembly shell 26 through the through hole 25. With the exhaust fan 28 and the filter screen 27 working together, the fibers that fall off the upper surface of the test platform 1 can be sucked into the assembly shell 26 through the through hole 25. The filter screen 27 filters and blocks the sucked-in fibers, keeping the test interface clean and preventing secondary entanglement.
