Description

Technical Field

[0001] This utility model relates to the field of fabric testing technology, specifically a pilling detection device for the production of high-speed rail seat fabric. Background Technology

[0002] With the rapid development of high-speed rail, it serves as an efficient and convenient mode of transportation. High-speed rail seats, being a crucial facility that passengers come into prolonged contact with during their journeys, directly impact passenger comfort and experience. Due to the long daily operating hours and high passenger volume of high-speed rail, the seats are used extremely frequently, subjecting the fabric to constant friction. Compared to textiles in ordinary environments, high-speed rail seat fabrics face more complex and demanding friction conditions, including frequent contact with passengers' bodies and potential abrasion from luggage and other items.

[0003] Currently, the mainstream method for detecting pilling in high-speed rail seat fabrics still relies on manually operated abrasion testers. Testers need to manually fix the fabric sample onto the instrument's sample tray and simulate the wear process by rotating the friction head. Completing a standard test takes 2-3 hours. However, in actual operation, due to the physical limitations of manual operation, long-term repetitive labor can easily lead to deviations in movement, affecting the consistency of friction pressure and angle. Therefore, we propose a pilling detection device for the production of high-speed rail seat fabrics to solve the above problems. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution: a pilling detection device for the production of high-speed rail seat fabric, comprising a base and an operating table mounted on the base. A rotary motor is installed on the left side of the top of the operating table. A brush disc and an abrasive disc are respectively arranged on both sides of the rotary motor. The opposite ends of the brush disc and the abrasive disc are connected to the output end of the rotary motor. A through groove is opened on the right side of the top of the operating table. A sliding rod is installed in the through groove. A sliding seat is slidably connected to the outside of the sliding rod. A support rod is installed on the top of the sliding seat. A crossbeam is installed on the top of the support rod. A guide hole is opened on the left end of the crossbeam. A guide rod is slidably connected in the guide hole. A pressure plate is fixed at the bottom end of the guide rod. A top plate is installed on the top end of the guide rod. A first linear actuator is arranged on the right side of the guide hole. The output end of the first linear actuator is connected to the bottom end of the top plate. A second linear actuator is installed at the rear end of the through groove. The output end of the second linear actuator is connected to the outer wall of the support rod. A fabric fixing component is installed on the top of the pressure plate.

[0006] As a further preferred embodiment of this technical solution, the fabric fixing assembly includes a fixing rod, a locking block, a movable sleeve plate, a pressure plate, a pull handle, a return spring, and a pressure groove. Two sets of fixing rods are installed on both the front and rear sides of the top of the pressure plate. The top of each set of fixing rods is fixed with a locking block, and a movable sleeve plate is provided on the outside of the two sets of fixing rods. A pressure plate is installed on the end of the movable sleeve plate away from the guide rod, and a pull handle is installed on the top of the movable sleeve plate. A return spring is wound around the outside of the fixing rod, and a pressure groove is provided on both the front and rear sides of the top of the pressure plate.

[0007] As a further preferred embodiment of this technical solution, a control box is installed on the right side of the top of the through slot, and the input terminals of the rotary motor, the first linear driver, and the second linear driver are all electrically connected to the control box through wires.

[0008] As a further preferred embodiment of this technical solution, the bottom ends of the pressure plate are designed with an arc shape on both sides.

[0009] As a further preferred embodiment of this technical solution, sliding holes corresponding to the fixed rods are provided on both sides of the movable sleeve plate, and the movable sleeve plate is slidably connected to the two sets of fixed rods through the sliding holes.

[0010] As a further preferred embodiment of this technical solution, the two ends of the reset spring are respectively connected to the outer wall of the movable sleeve plate and the outer wall of the locking block, and the movable sleeve plate is elastically connected to the two sets of locking blocks through two sets of reset springs.

[0011] This utility model provides a pilling detection device for the production of high-speed rail seat fabrics, which has the following features:

[0012] Beneficial effects:

[0013] 1. This utility model uses a rotary motor to drive a brush disc and an abrasive disc, achieving alternating rotation of the two discs to simulate the friction conditions of high-speed rail seat fabric. A movable slide block is installed in a slot on the right side of the operating table, allowing a second linear actuator to push the slide block laterally along the slide rod surface within the slot. A first linear actuator on the crossbeam controls the lifting and lowering of the top plate, enabling the guide rod to move the pressure plate into the brush disc or abrasive disc. The pressure of the pressure plate on the fabric sample is controlled, allowing the fabric sample to automatically rub against the brush disc or abrasive disc under the influence of the pressure plate. This effectively reduces manual intervention, improves testing efficiency, and ensures test consistency.

[0014] 2. This utility model has two sets of liftable pressure plates installed on the top of the pressure plate. The return spring outside the fixed rod can release its elastic force to push the movable sleeve plate downward. The two sets of movable sleeve plates can push the two sets of pressure plates downward, allowing the two sets of pressure plates to enter the two sets of pressure grooves. This effectively clamps and fixes the fabric in the two sets of pressure grooves, thereby preventing the fabric sample from shifting during friction and ensuring the accuracy of the test results.

[0024] This utility model provides a technical solution: such as Figures 1 to 4 As shown in this embodiment, a pilling detection device for the production of high-speed rail seat fabric includes a base 1 and an operating table 2 mounted on the base 1. A rotary motor 3 is installed on the left side of the top of the operating table 2. A brush disc 4 and an abrasive disc 5 are respectively arranged on both sides of the rotary motor 3. The opposite ends of the brush disc 4 and the abrasive disc 5 are connected to the output end of the rotary motor 3. A through groove 6 is opened on the right side of the top of the operating table 2. A slide rod 7 is installed in the through groove 6. A slide seat 8 is slidably connected to the outside of the slide rod 7. A support rod 9 is installed on the top of the slide seat 8. A crossbeam 10 is installed at the top, and a guide hole 11 is opened at the left end of the crossbeam 10. A guide rod 12 is slidably connected in the guide hole 11. A pressure plate 13 is fixed at the bottom end of the guide rod 12. A top plate 14 is installed at the top end of the guide rod 12. A first linear actuator 15 is provided on the right side of the guide hole 11. The output end of the first linear actuator 15 is connected to the bottom end of the top plate 14. A second linear actuator 16 is installed at the rear end of the through groove 6. The output end of the second linear actuator 16 is connected to the outer wall of the support rod 9. A fabric fixing component is installed at the top of the pressure plate 13.

[0025] The brush disk 4 and abrasive disk 5 are driven by a rotary motor 3 to achieve alternating rotation of the two disks, simulating the friction conditions of high-speed rail seat fabric. A movable slide block 8 is installed in the through groove 6 on the right side of the operating table 2, allowing the second linear actuator 16 to push the slide block 8 to move laterally on the surface of the slide rod 7 along the through groove 6. The first linear actuator 15 on the crossbeam 10 controls the lifting and lowering of the top plate 14, allowing the guide rod 12 to drive the pressure plate 13 to move into the brush disk 4 or abrasive disk 5, and to control the pressure of the pressure plate 13 on the fabric sample. The fabric sample is automatically rubbed in the brush disk 4 or abrasive disk 5 under the drive of the pressure plate 13, effectively reducing manual intervention, improving testing efficiency, and ensuring the consistency of the test.

[0026] In other embodiments, the fabric fixing assembly includes a fixing rod 17, a locking block 18, a movable sleeve plate 19, a pressure plate 20, a pull handle 21, a return spring 22, and a pressure groove 23. Two sets of fixing rods 17 are installed on the front and rear sides of the top of the pressure plate 13. The top of each set of fixing rods 17 is fixed with a locking block 18, and the two sets of fixing rods 17 are provided with a movable sleeve plate 19. The end of the movable sleeve plate 19 away from the guide rod 12 is equipped with a pressure plate 20. The top of the movable sleeve plate 19 is equipped with a pull handle 21. The fixed rods 17 are wrapped with a return spring 22. The top of the pressure plate 13 is provided with a pressure groove 23 on both the front and rear sides.

[0027] By installing two sets of liftable pressure plates 20 at the top of the pressure plate 13, when it is necessary to fix the fabric, pull the handle 21 upwards, so that the handle 21 drives the movable sleeve 19 and the pressure plate 20 to move upwards along the two sets of fixing rods 17. Then, the two ends of the fabric can be placed in the two sets of pressure grooves 23 at the top of the pressure plate 13. Then, the tension on the two sets of handles 21 can be released, so that the return spring 22 outside the fixing rod 17 can release the elastic force to push the movable sleeve 19 downwards, so that the two sets of movable sleeves 19 can push the two sets of pressure plates 20 downwards, so that the two sets of pressure plates 20 can enter the two sets of pressure grooves 23, effectively clamping and fixing the fabric in the two sets of pressure grooves 23, thereby preventing the fabric sample from shifting during friction and ensuring the accuracy of the test results.

[0028] In other embodiments, a control box 24 is installed on the right side of the top of the through slot 6, and the input terminals of the rotary motor 3, the first linear driver 15 and the second linear driver 16 are all electrically connected to the control box 24 through wires.

[0029] This design enables integrated control of the control box 24, simplifies the operation process, supports parameter settings such as the number of friction cycles and pressure values, and automates the detection process.

[0030] In other embodiments, the bottom ends of the pressure plate 13 are arc-shaped on both sides;

[0031] The curved design avoids additional wear on the fabric sample by the edge of the pressure plate 13, ensuring that the friction is applied only by the brush plate 4 and the abrasive plate 5, thus improving the reliability of the test results.

[0032] In other embodiments, sliding holes corresponding to the fixed rods 17 are provided on both sides of the movable sleeve 19, and the movable sleeve 19 is slidably connected to the two sets of fixed rods 17 through the sliding holes;

[0033] This design allows the movable sleeve 19 to move smoothly up and down along the two sets of fixed rods 17, thus ensuring the stability of the movable sleeve 19 during use.

[0034] In other embodiments, the two ends of the return spring 22 are respectively connected to the outer wall of the movable sleeve 19 and the outer wall of the locking block 18, and the movable sleeve 19 is elastically connected to the two sets of locking blocks 18 through the two sets of return springs 22;

[0035] This design allows the return springs 22 outside the two sets of fixed rods 17 to continuously apply downward elastic force to the crossbeam 10, allowing the movable sleeve 19 to drive the pressure plate 20 to move quickly to the outside of the pressure groove 23.

[0036] The electrical components mentioned in this article are all electrically connected to an external main controller and industrial power supply, and the main controller can be a conventional known device such as a computer that provides control.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
