[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] like Figure 1-Figure 5As shown, a fabric wrinkle resistance testing device comprises a base 1, a torsion assembly and a driving assembly, the torsion assembly comprises a transmission member 14 and two clamping members 9 arranged opposite to each other, the clamping member 9 comprises a slide seat 34, a rotating shaft 23 and a pressing block 25, a slide groove 33 for sliding the slide seat 34 is arranged on the base 1, the rotating shaft 23 is rotatably mounted on the slide seat 34, the middle part of the pressing block 25 is a semicircular ring structure, and two pressing blocks 25 are arranged, and one end of the fabric to be tested 2 or the control group fabric 13 is fixed on the rotating shaft 23 by bolts, a first guide rod 6 is arranged on the base 1, the first guide rod 6 is slidably arranged with the two slide seats 34 in the same clamping member 9, and a spring 26 is sleeved on the first guide rod 6, The spring 26 applies a force to move the two slides 34 in the same clamping member 9 away from each other. The driving assembly includes a motor 5, a worm 7, a transmission shaft 18, a worm wheel 8 and a steering member 3. Four transmission shafts 18 are provided, and they are coaxially arranged in groups of two. The steering member 3 is installed between the two transmission shafts 18 so that the two transmission shafts 18 turn in opposite directions. Two fixed seats 17 are provided on the base 1. One end of the transmission shaft 18 is rotatably connected to the fixed seat 17. The worm 7 is rotatably installed on one of the fixed seats 17. Two worm wheels 8 are provided and fixed at the same end of the two transmission shafts 18. The two worm wheels 8 are meshed with the worm 7 for transmission. Four transmission members 14 are provided and installed between the transmission shaft 18 and the rotating shaft 23.

[0020] The steering member 3 includes a mounting seat 10, a first bevel gear 12 and a second bevel gear 11. Two first bevel gears 12 are provided and fixed to the ends of two coaxially arranged transmission shafts 18. The second bevel gear 11 is rotatably arranged on the mounting seat 10 through a fixed axis. When one of the transmission shafts 18 rotates, it can drive the first bevel gear 12 to rotate, and the second bevel gear 11 can transmit power to the other first bevel gear 12. In this way, the two coaxially arranged transmission shafts 18 can rotate while ensuring that the rotation directions of the two are opposite, thereby achieving the effect of applying torque to the cloth.

[0021] The transmission member 14 includes a first gear 22, a second gear 24 and a synchronous member 16. The transmission shaft 18 has a first limiting portion 21, the first gear 22 is slidably mounted on the first limiting portion 21, and the first gear 22 and the first limiting portion 21 rotate synchronously, and the first gear 22 and the second gear 24 are meshed for transmission. The rotating shaft 23 is provided with a second limiting portion 30, the second gear 24 is slidably mounted on the second limiting portion 30, and the second gear 24 and the second limiting portion 30 rotate synchronously. The outer dimensions of the second limit portion 30 are larger than the diameter of the rotating shaft 23. The synchronous member 16 includes two sets of translation members, which are located on both sides of the first gear 22 and the second gear 24. The translation members include an upper pressure rod 20 and a lower pressure rod 19. The upper pressure rod 20 and the lower pressure rod 19 are both provided with an arc groove 32 that rotates with the first limit portion 21 and the rotating shaft 23. The upper pressure rod 20 and the lower pressure rod 19 are connected by bolts, and the two rotating shafts 23 are driven to rotate in different directions through the two transmission shafts 18. The cloth is twisted into a twist shape by applying a torque to the cloth. The tighter it is twisted, the harder the cloth is rolled up. At the same time, the middle part will shrink into a roll, shortening the overall length of the cloth. This applies a certain traction force to the two slides 34. When the two slides 34 are pulled and the distance between them becomes smaller, the shaft 23 can drive the second gear 24 to move synchronously. In order to ensure that the first gear 22 and the second gear 24 continue to mesh and allow the power of the transmission shaft 18 to continue to be transmitted to the shaft 23, the upper pressure rod 20 and the lower pressure rod 19 are fixed on both sides of the shaft 23 corresponding to the second gear 24. When the shaft 23 moves, it will drive the synchronous member 16 to move synchronously, so that the first gear 22 slides on the first limit portion 21, so that the transmission shaft 18 can continue to drive the shaft 23 to rotate. In this process, no relative sliding occurs between the first gear 22 and the second gear 24, which can effectively avoid additional wear between the two and affect their service life.

[0022] A second guide rod 15 is also arranged between the two fixed seats 17. Each second guide rod 15 and the transmission shaft 18 are symmetrically arranged with the rotating shaft 23 as the center. The upper pressure rod 20 and the lower pressure rod 19 are also provided with an arc groove 32 that rotates with the second guide rod 15. The installation positions of the two groups of translation parts installed on the transmission shaft 18, the rotating shaft 23 and the second guide rod 15 are equal in spacing, which can ensure the stability of the translation part when driving the first gear 22 to slide.

[0023] A limit member 4 for limiting the sliding distance of the slide 34 is provided on the base 1. The limit member 4 includes a fixed block 27 and a limit bolt 28. The fixed block 27 is fixed to the base 1 by bolts. The limit bolt 28 is threadedly connected to the fixed block 27, and one end of the limit bolt 28 is arranged toward the slide 34. By rotating the limit bolt 28, the sliding distance of the slide 34 can be changed, thereby indirectly controlling the length of the cloth after being twisted into a twist shape. In this way, the test conditions can be changed, and data and results under different test conditions can be obtained.

[0024] The pressing block 25 is provided with an arc-shaped convex strip 29, and the rotating shaft 23 is provided with an annular groove 31 which cooperates with the arc-shaped convex strip 29. The arc-shaped convex strip presses the cloth into the annular groove 31, which can effectively increase the friction force after clamping the cloth, thereby preventing the cloth from falling off and ensuring the smooth progress of the cloth wrinkle resistance test.

[0025] Working principle: The two ends of the test cloth 2 and the control cloth 13 are fixed on the two sets of clamping parts 9 respectively. When fixing, first remove the pressing block 25, wrap the test cloth 2 or the control cloth 13 on the end of the rotating shaft 23, and then fix the two pressing blocks 25 by bolts, so that the arc-shaped convex strips 29 press the cloth into the annular groove 31, so that the ends of the cloth are fixed and the anti-slip effect can be achieved. When the test cloth 2 and the control cloth 13 are fixed, the motor 5 drives the worm 7 to rotate, so that the two worm wheels 8 keep rotating in the same direction, and drive the transmission shaft 18 close to the side of the worm 7 to rotate, and under the action of the steering member 3, the other two transmission shafts 18 are also turned. The two coaxial transmission shafts 18 start to rotate, and the rotation directions of the two transmission shafts 18 are opposite, and the rotating shaft 23 realizes power transmission with the transmission shaft 18 through the transmission member 14. When the transmission shaft 18 drives the first gear 22 to rotate, the second gear 24 meshes with the first gear 22 to drive the rotating shaft 23 to rotate. In this way, the two rotating shafts 23 can be used to apply torques in two rotation directions to the test fabric 2 or the control fabric 13, and the effect is equivalent to twisting a twist, so as to perform a wrinkle resistance test on the test fabric 2. After the fabric test is completed, it is flattened, and then the test fabric 2 and the control fabric 13 are compared. Since the test conditions applied to the two are the same, it is only necessary to check the number of wrinkles on the surfaces of the two fabrics to make a judgment.

[0026] In the process of applying torque to the cloth, the cloth is rolled into a twist shape due to the torque. When the degree of twisting becomes larger, the length of the cloth will be shorter than the normal length, and thus a traction force is generated on the two slides 34. In order to continue to ensure the rotation of the shaft 23, the rotation power of the transmission shaft 18 is transmitted to the shaft 23, the first gear 22 and the transmission shaft 18 are slidably arranged through the first limit portion 21, and two sets of translation parts are used at the same time. When the slide 34 drives the shaft 23 to rotate, the shaft 23 will drive the two sets of translation parts to move synchronously, so that the first gear 22 can rotate. When the first gear 22 remains in meshing with the second gear 24, the first gear 22 can slide on the first limiting portion 21, so that the transmission shaft 18 can drive the first gear 22 to rotate without affecting the sliding between the two, so that the anti-wrinkle performance test of the test fabric 2 can be carried out according to different test conditions. In the method of this embodiment, the test fabric is in the form of a twisted knot, which also imitates the state of washing and wringing clothes in disguise. In this process, the number of creases and the direction of the creases are sufficient, so that the final test result is more convincing.

[0027] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention.

This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
