Technical Field

[0001] This utility model relates to the field of textile surface testing technology, specifically a device for detecting pilling and wear on the surface of polyester textiles. Background Technology

[0002] Fabrics are common in our lives. They can be used to make clothing and as decorative materials. When used as decorative materials, fabrics can be divided into chemical fiber fabrics, non-woven fabrics, nylon fabrics, etc. When used as clothing materials, fabrics can be divided into cotton fabrics, linen fabrics, woolen fabrics, polyester fabrics, etc. There are many types. All types of fabrics must undergo anti-pilling and abrasion resistance tests during processing to ensure the efficiency of the fabrics in the later stages of use and to facilitate the further differentiation of fabrics based on anti-pilling and abrasion resistance. Therefore, the use of anti-pilling performance testing devices plays an important role in fabric processing.

[0003] A pilling resistance testing device for polyester fabric production, disclosed in authorization announcement number CN223078117U, includes a placement plate with mating grooves at the four corners of its upper surface and a mounting frame fixed in the middle of the placement plate; a pressure plate fixed to the output end of a telescopic cylinder on the mounting frame; a movable component located in the middle of the lower surface of the pressure plate for moving a testing component; and a testing component located at the bottom of the movable component for performing pilling resistance testing on the fabric.

[0004] Existing devices for detecting pilling and wear on polyester textile surfaces use friction blocks to rub the surface of the polyester textile to detect its pilling and wear resistance. However, the contact force between the friction blocks and the surface of the polyester textile is fixed during testing, making it difficult to detect the pilling and wear conditions of the polyester textile surface under different friction forces. Utility Model Content

[0005] The purpose of this invention is to solve the problem of inconvenience in detecting the pilling and wear of polyester textile surfaces under different friction forces, and to propose a device for detecting the pilling and wear of polyester textile surfaces.

[0006] To achieve the above objectives, this utility model provides the following technical solution: Design a device for detecting pilling and abrasion on the surface of polyester textiles, including a base and a top plate. The base is fixedly connected to the top plate by a support column. A first electric push rod is fixedly connected inside the top plate. A first support plate is fixedly connected to the output end of the first electric push rod. A rotating rod is rotatably connected inside the first support plate through a bearing. A first bracket is fixedly connected to the lower end of the rotating rod. A pressing mechanism is provided inside the first bracket.

[0007] Preferably, the extrusion mechanism includes a first motor, which is fixedly connected inside a first bracket. A screw is fixedly connected to the output shaft of the first motor. The outer wall of the upper end of the screw is rotatably connected to the first bracket via a bearing. A threaded cylinder is threadedly connected to the outer wall of the screw, and the outer wall of the threaded cylinder is slidably connected to the first bracket. A sliding rod is slidably connected inside the threaded cylinder. A spring is installed inside the threaded cylinder, with both ends of the spring fixedly connected to the threaded cylinder and the sliding rod, respectively. A connecting block is fixedly connected to the lower end of the sliding rod. A groove in the connecting block is clearance-fitted with the outer wall of the block. A friction block is fixedly connected below the connecting block, with its upper surface abutting against the connecting block. A locking bolt is threadedly connected to the inner thread of the connecting block, and the outer wall of the end of the locking bolt is threadedly connected to the groove in the block.

[0008] Preferably, two sliders are fixed to the outer wall of the first support plate, and the outer wall of the sliders is slidably connected to a groove provided in the top plate.

[0009] Preferably, a second motor is fixedly connected to the upper surface of the first support plate, and the output shaft of the second motor is fixedly connected to the rotating rod.

[0010] Preferably, two second brackets are fixedly connected to the upper surface of the base, and a second electric push rod is fixedly installed on the inner wall of the second bracket.

[0011] Preferably, the output end of the second electric push rod is fixedly connected to a second support plate, and both second support plates are fixedly connected to the outer wall of the spiral frame.

[0012] Preferably, the outer wall of the spiral frame is fitted with the spiral groove with a clearance, and the spiral groove is located inside the base.

[0013] Preferably, a battery is fixedly installed on the upper surface of the top plate, and a controller is fixedly installed on the lower surface of the top plate. Both the battery and the controller are electrically connected to the first motor, the second motor, the first electric push rod, and the second electric push rod.

[0014] The present invention provides a device for detecting pilling and wear on the surface of polyester textiles. The advantages are as follows: The second motor continues to start, and the threaded cylinder moves downwards. At this point, the friction block is already in contact with the surface of the polyester textile. The contact position of the friction block with the surface of the polyester textile will not decrease. The sliding rod slides into the threaded cylinder and compresses the spring. The spring reduces the hard contact between the friction block and the polyester textile, reducing damage caused by the friction block's hardness. After the spring is compressed, its elasticity allows the friction block to maintain close contact with the polyester textile, increasing the frictional force. A pressure sensor inside the friction block detects the pressure between the friction block and the polyester textile. The friction block continues to rub the surface of the polyester textile, observing the pilling and wear conditions. This allows for the detection of pilling and wear on the surface of the polyester textile under different pressure friction conditions, facilitating the detection of pilling and wear on the surface of the polyester textile under different friction forces, thus achieving the detection of the degree of pilling and wear on the surface of the polyester textile.

[0015] Lay the polyester textile to be tested flat on the upper surface of the base, ensuring that the textile covers the top of the groove. Activate the second electric push rods on both sides, which drive the second support plate to move. The second support plate on both sides then moves the groove frame, which contacts the polyester textile and presses it into the groove. The groove frame and the groove work together to fix the position of the polyester textile. The groove frame positions the polyester textile around its perimeter to prevent the edges of the textile from shrinking during testing, which would affect the test results.

[0021] Working principle: When using a device to detect pilling and abrasion on the surface of polyester textiles, the polyester textile to be tested is laid flat on the upper surface of the base 1, ensuring it covers the top of the groove 14. The second electric push rods 11 on both sides are activated, driving the second support plates 12 to move. The second support plates 12 then move the groove frame 13, which contacts the polyester textile and presses it into the groove 14. The groove frame 13 and the groove 14 work together to fix the position of the polyester textile. The groove frame 13 positions the polyester textile around its perimeter to prevent the edges from shrinking during testing, which would affect the test results. A pressure sensor is installed inside the friction block 308; the sensor model should meet the operational requirements. The pressure sensor can... Knowing the pressure of friction block 308 on polyester textile, the first motor 301 is started. The first motor 301 drives the screw 302 to rotate, and the screw 302 drives the threaded cylinder 303 to slide downward. Then, the slide bar 304, connecting block 306 and friction block 308 move downward, and friction block 308 comes into contact with polyester textile. The first motor 301 is turned off, and the second motor 7 is started. The second motor 7 drives the rotating rod 8 to rotate, and the rotating rod 8 drives the first support 9 to rotate. When the first support 9 rotates, friction block 308 rotates accordingly. Friction block 308 rubs the surface of polyester textile, thus simulating the friction of polyester textile when worn. The first electric push rod 4 is started, and the first electric push rod 4 drives the first support plate 5 to move, thus driving friction block 308 to move left and right. Friction block 308 rubs different positions on the surface of polyester textile, and the pilling and wear of the polyester textile surface are observed. The second motor 7 is started again, and the threaded cylinder 303 moves downward. At this time, the friction block 308 is already in contact with the surface of the polyester textile. The position of the friction block 308 in contact with the surface of the polyester textile will not drop. The slide rod 304 slides into the threaded cylinder 303 and compresses the spring 305. The spring 305 reduces the hard contact between the friction block 308 and the polyester textile, reducing the damage to the polyester textile caused by the friction block 308 due to its hardness. After the spring 305 is compressed, the spring 305 will make the friction block 308 and the polyester textile in close contact under the action of elasticity, increasing the friction force between the friction block 308 and the polyester textile. The pressure sensor installed in the friction block 308 detects the pressure between the friction block 308 and the polyester textile. The friction block 308 continues to rub the surface of the polyester textile, and the pilling and wear of the polyester textile surface are observed. It is known that the polyester textile pilling and wear under different pressure friction conditions are facilitating the detection of the pilling and wear of the polyester textile surface under different friction forces, thereby realizing the detection of the degree of pilling and wear of the polyester textile surface.
