Description

Technical Field

[0001] The present invention relates to the technical field of textile testing equipment, and in particular to a testing device for pilling and abrasion resistance of textiles. Background Art

[0002] Fabric abrasion resistance testing refers to conducting a friction test on textile products to test the abrasion resistance characteristics of the fabric. Abrasion resistance is an important indicator of the quality of textile products, which directly affects the durability, use effect, and appearance of the products. Abrasion resistance refers to the property of a fabric to resist wear during repeated friction between fabrics or with other substances. To control the quality of textile products, it is necessary to strictly detect the abrasion resistance of textiles to prevent quality problems. Therefore, textile abrasion resistance testing plays a very important role in related industrial production. Among them, the pilling performance of a fabric is the process of generating pills on the fabric surface, which is an important performance indicator of textiles. The testing principle mainly simulates the actual wearing and washing processes, during which textiles are continuously subjected to friction, resulting in the appearance of pills on the surface. The tumbling box pilling tester is used to test the pilling degree of fabrics, especially wool knitted fabrics, without pressure. Specifically, the specimen is put on a polyurethane tube and placed in a square tumbling box lined with friction pads, and then tumbled randomly at a constant rotation speed. After a certain tumbling time, the specimen is visually rated for pilling.

[0003] In the prior art, the utility model with the application number CN201720066875.0 discloses a textile tumbling box pilling tester, which includes a base. A housing is provided on the base. A motor base is provided inside the housing. A motor is installed on the motor base. A driving V-belt pulley is installed on the output shaft of the motor. A lower rotating shaft is also provided inside the housing. A driven V-belt pulley cooperating with the driving V-belt pulley is provided on the lower rotating shaft. Both ends of the lower rotating shaft extend out of the housing. A pedestal bearing for supporting the lower rotating shaft is provided on the inner side wall of the housing. Fixed blocks are provided at both ends of the lower rotating shaft extending out of the housing. A tumbling box is fixedly installed on the fixed blocks. However, this patent still has some deficiencies: 1. During the testing process, the fibers of the textile are likely to fall into the tumbling box, which is not only difficult to clean, but also the fallen fibers repeatedly rub against the textile, which will affect the result of the pilling and abrasion resistance test. 2. During the process of the textile rubbing repeatedly inside the tumbling box, a large amount of static electricity will be generated, and the operator is likely to be electrocuted when taking out the textile.

DETAILED DESCRIPTION

[0023] The technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0024] like Figures 1 to 6 As shown, the present invention provides an embodiment of a textile pilling and abrasion resistance testing device, comprising a base 1, a shell 2 is arranged on the base 1, a motor is arranged in the shell 2, spindles 3 are rotatably mounted on both sides of the shell 2, the spindle 3 is transmission-connected to the output shaft of the motor through a pulley set, and also comprises a rolling box 4 and a fixed plate 5, an outward-opening door 6 is arranged on the front of the rolling box 4, and the rolling box 4 is provided with multiple rolling boxes, the rolling box 4 is used to place test fabrics 7, the fixed plate 5 is fixed on one side of the rolling box 4, the spindle 3 passes through the fixed plate 5 and is coaxially fixedly connected with the fixed plate 5, and the end of the spindle 3 is located on the inner side of the rolling box 4.

[0025] A cleaning mechanism 8 and a static elimination mechanism 9 are also provided in the rolling box 4. The cleaning mechanism 8 includes a rotating sleeve 10, a rod seat 11, a sliding rod 12 and a rolling brush 13. The rotating sleeve 10 is rotatably installed on one end of the main shaft 3 located in the rolling box 4, the rod seat 11 is vertically fixed on the outer wall of the rotating sleeve 10, the sliding rod 12 is inserted in the rod seat 11, and the rolling brush 13 is rotatably installed on the sliding rod 12, and the rolling brush 13 is always in contact with the inner wall of the rolling box 4.

[0026] The cleaning mechanism 8 also includes a counterweight head 15, a compression spring 16 and a spring plate 17. The counterweight head 15 is fixed at the bottom of the slide bar 12. The weight of the counterweight head 15 is greater than the sum of the weights of the cleaning mechanism 8 and the static elimination mechanism 9. Therefore, during the rotation of the roller box 4, the counterweight head 15 is always located at a lower position, while the cleaning mechanism 8 and the static elimination mechanism 9 are always located at a higher position, so that the roller brush 13 and the contact sheet 14 can abut against the position close to the upper side when the roller box 4 rotates, and when the roller box 4 rotates, the test fabric 7 is always located at the lower position of the rotating roller box 4 due to the action of gravity, thereby preventing the test fabric 7 from being damaged when the roller brush 13 comes into contact with the roller brush 13.

[0027] The counterweight head 15 is used to keep the sliding rod 12 in an inclined state and the counterweight head 15 always leans downward. The spring plate 17 is fixed at a position near the upper end of the sliding rod 12. The compression spring 16 is sleeved on the sliding rod 12. The two ends of the compression spring 16 are respectively abutted against the rod seat 11 and the spring plate 17. The compression spring 16 is used to push the sliding rod 12 to move upward along the length direction of the sliding rod 12. That is, after the upper end of the sliding rod 12 tilts up, during the rolling process of the square rolling box 4, the height position where the rolling box 4 contacts the rolling brush 13 is constantly changing. At this time, by pushing the sliding rod 12 upward through the compression spring 16, the rolling brush 13 can always be in contact with the inner wall of the rolling box 4, improving the cleaning effect on the inner wall of the rolling box 4.

[0028] A semi-circular tile support 18 is fixed at the top end of the sliding rod 12. Slots are opened at both ends of the semi-circular tile support 18. Plug-in fixing seats 19 are rotatably connected to both ends of the rolling brush 13. The plug-in fixing seats 19 can be engaged with the slots at both ends of the semi-circular tile support 18.

[0029] An arc-shaped cleaning plate 20 is detachably connected to the outside of the semi-circular tile support 18. A plurality of comb teeth 21 are evenly arranged on the inner side of the arc-shaped cleaning plate 20. A plurality of through holes are opened on the semi-circular tile support 18. The comb teeth 21 can be inserted into the through holes. When the arc-shaped cleaning plate 20 is attached to the semi-circular tile support 18, the ends of the comb teeth 21 can be inserted into the gaps of the rolling brush 13. During the process of the rolling brush 13 rolling along the inner wall of the rolling box 4, the fibers falling from the fabric will adhere to the rolling brush 13. In order to maintain the cleaning effect of the rolling brush 13, when the rolling brush 13 contacts the comb teeth 21, the fibers adhered to the rolling brush 13 will be pulled off by the comb teeth 21 and retained in the semi-circular tile support 18. When the test is completed, the rolling brush 13 can be removed first, and then the arc-shaped cleaning plate 20 can be removed. When the arc-shaped cleaning plate 20 is separated from the semi-circular tile support 18, the comb teeth 21 are also pulled out of the through holes of the semi-circular tile support 18 at the same time. Therefore, no fibers will remain on the comb teeth 21, and the fibers falling from the fabric will be blocked in the semi-circular tile support 18. At this time, the residual fibers in the semi-circular tile support 18 can be cleaned.

[0030] The static electricity elimination mechanism 9 includes a contact piece 14. One side of the contact piece 14 is connected to the sliding rod 12. The other side of the contact piece 14 can be attached to the inner wall of the rolling box 4. The static electricity elimination mechanism 9 also includes a connecting shaft 22, a connecting plate 23 and a support frame 24. The connecting shaft 22 is rotatably installed on the sliding rod 12. The connecting plate 23 is fixedly connected to one end of the connecting shaft 22. The other end of the connecting shaft 22 is connected to the sliding rod 12 through a torsion spring. The support frame 24 is fixed on the connecting plate 23. The contact piece 14 is a metal piece. The contact piece 14 is fixed on the support frame 24. By contacting the inner wall of the rolling box 4 through the contact piece 14, the electric charges accumulated in the rolling box 4 can be released through the contact piece 14.

[0031] The weight head 15 adopts a metal sphere structure. During the rotation of the rolling box 4, the test fabric 7 inside the rolling box 4 occasionally touches the metal sphere during the movement, and the charge accumulated on the test fabric 7 is released through the metal sphere, achieving the effect of eliminating static electricity and preventing the operator from being electrocuted when taking out the test fabric 7. The rotating sleeve 10, rod seat 11, sliding rod 12, connecting shaft 22, connecting plate 23, and support frame 24 are all made of metal and conduct electricity with the ground wire to release the charge near the contact piece 14.

[0032] The rotary brush 13 adopts a steel wire rotary brush 13 or a carbon fiber rotary brush 13, enabling the rotary brush 13 to conduct electricity and further preventing static electricity from generating.
