Description

Technical Field

[0001] This utility model relates to the field of color fastness testing technology for textiles, and in particular to a color fastness tester for dry and wet rubbing of textiles. Background Technology

[0002] Textile products inevitably suffer from sun exposure, wind, and rain during use. They also experience various frictions, close contact with different types of raw materials and colors, and are soaked in sweat, saliva, and other secretions. To maintain their cleanliness, these textiles need to be washed or dry-cleaned. The testing of fabric color fastness can not only evaluate the color fastness quality of textile products, but also predict their future use. Fabric color fastness is not only a very important quality indicator, but also relates to the effective lifespan and aesthetics of textiles for consumers. Therefore, the testing of fabric color fastness is a very important test.

[0003] Regarding the above-mentioned and existing related technologies, the inventor believes that the following defects often exist: when staff need to test the color fastness of fabrics, they need to manually polish the fabric repeatedly, or use equipment to manually polish the fabric, which leads to long time consumption and increased workload of staff. At the same time, it also causes uneven polishing and inaccurate test results. Therefore, in order to address the above problems, a dry and wet rubbing color fastness tester for textiles is proposed. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies, such as long processing time, increased workload for staff, uneven manual polishing, and inaccurate test results. This invention provides a textile dry and wet rubbing color fastness tester.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a textile dry and wet rubbing color fastness tester, comprising a machine base, a housing fixedly connected to the surface of the machine base, a slide rail fixedly connected to the surface of the machine base, the slide rail being located inside the housing, two slide seats slidably connected to the inner surface of the slide rail, a friction swing arm hinged to the surface of the slide seats, a self-aligning seat fixedly connected to the upper surface of the slide seats, an eccentric connecting rod slidably connected inside the self-aligning seat, a push-pull motor fixedly connected to one end of the eccentric connecting rod, a bracket fixedly connected to the surface of the machine base, the bracket being fixedly connected to one side of the push-pull motor, lifting brackets provided on both sides of the friction swing arm, lifting blocks slidably connected inside the lifting brackets, threaded nuts inserted into the lifting blocks, a lifting stepper motor fixedly connected to one end of the threaded nuts, the surface of the lifting stepper motor being fixedly connected to the machine base, a friction head fixedly connected to one side of the friction swing arm, and a test switch installed on the surface of the machine base.

[0006] The aforementioned components achieve the following effects: they facilitate color fastness testing by rapidly rubbing the fabric, avoiding the need for manual and repeated polishing of the fabric by staff or manual polishing of the fabric by equipment when conducting color fastness testing, which would result in long processing times and increased workload for staff. In addition, manual polishing could lead to uneven results and inaccurate test results, thus improving the practicality of the device.

[0007] Preferably, a retaining ring is installed on the arc surface of the friction head.

[0008] The aforementioned components achieve the following effects: they facilitate use, reduce the hassle of staff searching for fixed objects, and prevent small pieces of fabric on the friction head from shifting, thus affecting the friction efficiency with larger fabrics.

[0009] Preferably, the machine tool surface has a groove, a base plate is fixedly connected to the surface of the groove, a guide rail is fixedly connected to the surface of the base plate, two limiting rails are fixedly connected to the surface of the base plate, two limiting pulleys are fixedly connected to the surface of the machine tool, a friction table is slidably connected to the surface of the guide rail, the friction table is slidably connected to the limiting pulleys, four connecting seats are fixedly connected to the surface of the friction table, a fixed seat is slidably connected to the inner surface of the connecting seat, a clamp is rotatably connected to the side of two fixed seats that are close to each other, a spring is fixedly connected to the lower surface of the fixed seat, and the end of the spring away from the fixed seat is fixedly connected to the machine tool.

[0010] The aforementioned components achieve the following effects: they clamp the large fabric to be tested, and they also clamp fabrics of different thicknesses, thus avoiding the situation where the large fabric shifts position during the friction process, affecting the test results or making it difficult to clamp the fabric afterward.

[0011] Preferably, one end of the clamp is fixedly connected to a rotating shaft, the arc surface of the rotating shaft is slidably connected to the fixed seat, and one end of the rotating shaft is fixedly connected to a handle knob.

[0012] The effect achieved by the above components is to facilitate workers to quickly place large fabrics, and to avoid situations where the clamps and the surface of the friction table are too close, making it difficult to place large fabrics.

[0013] Preferably, a stainless steel plate is fixedly connected to the surface of the clamp, and the surface of the stainless steel plate is provided with several anti-slip textures.

[0014] The effects achieved by the above components are as follows: the stainless steel plate prevents the clamp from having too low a surface friction with the large fabric, thus preventing insufficient clamping force and displacement. At the same time, the anti-slip texture of the stainless steel plate further improves the clamping stability of the large fabric on the friction table.

[0015] Preferably, the surface of the machine tool is provided with a sliding groove, a protective frame is slidably connected to the surface of the sliding groove, a connecting plate is fixedly connected to one side of the protective frame, a drive rod is threaded into the connecting plate, a connecting block is fixedly connected to one end of the drive rod, and the connecting block abuts against the surface of the machine tool.

[0016] The aforementioned components achieve the following effect: they protect the test switch, preventing accidental activation by staff during use, which could force the test switch to shut down and thus affect the test results.

[0017] Preferably, a positioning rod is fixedly connected to the side of the connecting block near the drive rod, and the arc surface of the positioning rod is slidably connected to the connecting plate.

[0018] The effect achieved by the above components is that the positioning rod restricts the connecting block from rotating with the drive rod, thereby increasing the stability of the connecting block against the machine surface.

[0019] In summary, the beneficial effects of this utility model are as follows:

[0020] This invention achieves the effect of quickly rubbing the fabric to facilitate color fastness testing, avoiding the need for workers to manually and repeatedly polish the fabric or use equipment to manually polish the fabric when testing color fastness, which would result in long processing time, increased workload for workers, uneven polishing, and inaccurate test results, thus improving the practicality of the device.

[0027] Reference Figure 1-5As shown, this utility model provides a technical solution: a textile wet and dry rubbing color fastness tester, including a machine base 1, a housing 2 fixedly connected to the surface of the machine base 1, a slide rail 3 fixedly connected to the surface of the machine base 1, the slide rail 3 being located inside the housing 2, two slide seats 4 slidably connected to the inner surface of the slide rail 3, a friction swing arm 6 hinged to the surface of the slide seat 4, a self-aligning seat 5 fixedly connected to the upper surface of the slide seat 4, an eccentric connecting rod 7 slidably connected inside the self-aligning seat 5, a push-pull motor 8 fixedly connected to one end of the eccentric connecting rod 7, a bracket 9 fixedly connected to the surface of the machine base 1, the bracket 9 being fixedly connected to one side of the push-pull motor 8, lifting brackets 9 being provided on both sides of the friction swing arm 6, lifting blocks 12 slidably connected inside the lifting brackets 9, and threaded nuts 1 threaded into the lifting blocks 12. 1. A lifting stepper motor 13 is fixedly connected to one end of a wire nut 11. The surface of the lifting stepper motor 13 is fixedly connected to the machine base 1. A friction head 14 is fixedly connected to one side of the friction swing arm 6. A test switch 27 is installed on the surface of the machine base 1. When testing the color fastness or abrasion resistance of the fabric, a large piece of fabric is first placed on the machine base 1, and a small piece of fabric is fixed to the lower end of the friction head 14. Then, the test switch 27 is activated, and the controller sends a command to the lifting stepper motor 13. The lifting stepper motor 13 drives the lifting wire nut 11 to rotate, causing the lifting block 12 to descend. Since the friction swing arm 6 rests on the lifting block 12, when the lifting block 12 descends, the friction swing arm 6 will fall along with it until the friction head 14 presses down on the large piece of fabric. Then, the controller sends another command. When the push-pull motor 8 is activated, it drives the eccentric connecting rod 7, causing the follower seat 5 and the slide 4 to reciprocate along the slide rail 3. This causes the small piece of fabric on the friction head 14 to rub back and forth against the larger piece of fabric. The machine stops after a preset number of rubs. This allows for the testing of color fastness and abrasion resistance. It achieves the effect of rapid rubbing of the fabric for color fastness testing, avoiding the need for manual and repeated polishing of the fabric by operators, which is time-consuming and increases the workload of operators. It also prevents uneven polishing and inaccurate test results, thus improving the practicality of the device. A retaining ring 15 is installed on the arc surface of the friction head 14. The retaining ring 15 is used to bind small pieces of fabric to the friction head 14, achieving a convenient use effect and reducing the hassle of finding fixing objects for the operator. It also prevents small pieces of fabric from shifting on the friction head 14, which could affect the friction efficiency with larger fabrics. A groove is formed on the surface of the machine base 1. A base plate 16 is fixedly connected to the surface of the groove. A guide rail 17 is fixedly connected to the surface of the base plate 16. Two limiting rails 18 are fixedly connected to the surface of the base plate 16. Two limiting pulleys 19 are fixedly connected to the surface of the machine base 1. A friction table 20 is slidably connected to the surface of the guide rail 17. The friction table 20 is slidably connected to the limiting pulleys 19. Four connecting seats 21 are fixedly connected to the surface of the friction table 20.A fixed seat 23 is slidably connected to the inner surface of the connecting seat 21. A clamp 22 is rotatably connected to the side of the two fixed seats 23 that are close to each other. A spring 33 is fixedly connected to the lower surface of the fixed seat 23. The end of the spring 33 away from the fixed seat 23 is fixedly connected to the machine base 1. When testing the color fastness or abrasion resistance of the fabric, a large piece of fabric is first placed on the friction table 20. The front and rear clamps 22 are used to press the fabric against both sides. Since the clamps 22 are equipped with springs 33 at both ends, they can elastically press the front and rear sides of the fabric when facing fabrics of different thicknesses. This has strong versatility and achieves the effect of clamping the large piece of fabric to be tested, as well as the effect of clamping fabrics of different thicknesses, avoiding the need for friction on the large piece of fabric. In cases where large fabric pieces shift position, affecting test results or becoming difficult to clamp, a rotating shaft 24 is fixedly connected to one end of the clamp 22. The arc surface of the rotating shaft 24 is slidably connected to the fixed base 23. A handle knob 26 is fixedly connected to one end of the rotating shaft 24. When placing large fabric pieces, the operator can rotate the handle knob 26, which drives the rotating shaft 24 to rotate, thus rotating the clamp 22. This facilitates quick placement of large fabric pieces and prevents the clamp 22 from being too close to the surface of the friction table 20, which would otherwise make it difficult to place large fabric pieces. A stainless steel plate 25 is fixedly connected to the surface of the clamp 22. The surface of the stainless steel plate 25 has several anti-slip textures. The stainless steel plate 25 prevents insufficient clamping force and displacement caused by low surface friction between the clamp 22 and the large fabric. Simultaneously, the anti-slip texture of the stainless steel plate 25 further enhances the clamping stability of the large fabric on the friction table 20. A sliding groove is provided on the surface of the machine base 1, and a protective frame 28 is slidably connected to the surface of the sliding groove. A connecting plate 29 is fixedly connected to one side of the protective frame 28, and a drive rod 30 is threaded into the connecting plate 29. A connecting block 31 is fixedly connected to one end of the drive rod 30, and the connecting block 31 abuts against the surface of the machine base 1. After the operator sets the data, the test switch 27 is turned on. At this time, the protective frame 28 is pushed, causing it to slide within the sliding groove of the machine base 1 until the protective frame 28... When the test switch is blocked, the drive rod 30 is rotated. The drive rod 30 moves within the thread of the connecting plate 29, simultaneously driving the connecting block 31 to move until the connecting block 31 abuts against the surface of the machine base 1. This achieves the effect of protecting the test switch 27, preventing accidental activation of the test switch 27 during use, which would force the test switch 27 to close and affect the test results. A positioning rod 32 is fixedly connected to the side of the connecting block 31 near the drive rod 30. The arc surface of the positioning rod 32 is slidably connected to the connecting plate 29. At this time, the positioning rod 32 restricts the rotation of the connecting block 31 with the drive rod 30, thereby increasing the stability of the contact between the connecting block 31 and the surface of the machine base 1.

[0028] Working principle: When testing the color fastness or abrasion resistance of fabrics, a large piece of fabric is first placed on the friction table 20 and pressed against both sides of the fabric by the front and rear clamps 22. Since springs 33 are provided at both ends of the clamps 22, they can elastically press against the front and rear sides of the fabric with different thicknesses, making them highly versatile. At this time, the fixing ring 15 is removed from the upper end of the friction head 14. Then, a small piece of fabric is wrapped around the lower end of the friction head 14, and the fixing ring 15 is fitted onto the lower end of the friction head 14. Through the cooperation of the two, the small piece of fabric is fixed to the lower end of the friction head 14. Then, the test switch 27 is activated, and the controller sends a command to the lifting stepper. Motor 13, the lifting stepper motor 13 drives the lifting wire nut 11 to rotate, causing the lifting block 12 to descend. Since the friction swing arm 6 is placed on the lifting block 12, when the lifting block 12 descends, the friction swing arm 6 will fall along with it until the friction head 14 presses on the large piece of fabric. Then the controller sends a command to the push-pull motor 8. The push-pull motor 8 works, which drives the eccentric connecting rod 7 to move. Thus, the follower seat 5 and the slide seat 4 move back and forth along the slide rail 3, causing the small piece of fabric on the friction head 14 to rub back and forth on the large piece of fabric. When the preset number of rubbing times is reached, the machine stops. This allows for the detection of color fastness and abrasion resistance. This achieves the effect of quickly rubbing the fabric to facilitate color fastness testing, avoiding the need for staff to manually and repeatedly polish the fabric when testing its color fastness, or to manually polish the fabric using equipment, which would be time-consuming and increase the workload of staff. It would also cause uneven polishing and inaccurate test results, thus improving the practicality of the device.
