Description

Technical Field

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

[0002] Fabric wear test refers to the friction test of textile products, and the wear resistance of fabrics is tested through this test. Wear resistance is an important indicator of textile product quality, which directly affects the durability, use effect and appearance of the product. Wear resistance refers to the property of fabrics to resist wear during repeated friction between fabrics or other substances. In order to control the quality of textiles, it is necessary to strictly test the wear resistance of textiles to prevent quality problems. Therefore, the wear resistance test of textiles plays a very important role in related industrial production. Among them, the pilling performance of fabrics is the process of generating hair balls on the surface of fabrics. It is an important performance indicator of textiles. The test principle is mainly to simulate the actual wearing and washing process. The textiles are constantly subjected to friction, resulting in hair balls on the surface. The rolling box pilling tester is used for fabrics, especially wool knitted fabrics, to test the pilling degree of fabrics under no pressure. Specifically, the sample is put on a polyurethane tube and placed in a square rolling box lined with friction pads, and then rolled at a constant rotation speed. After a certain rolling time, the sample is visually graded for pilling.

DETAILED DESCRIPTION

[0016] 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.

[0017] 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.

[0018] 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.

[0019] 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.

[0020] The counterweight head 15 is used to keep the slide bar 12 in an inclined state and the counterweight head 15 is always downward. The spring plate 17 is fixed to the slide bar 12 near the upper end. The compression spring 16 is sleeved on the slide bar 12. The two ends of the compression spring 16 are respectively in contact with the rod seat 11 and the spring plate 17. The compression spring 16 is used to push the slide bar 12 to move upward along the length direction of the slide bar 12. That is, after the upper end of the slide bar 12 is tilted, the height position of the square rolling box 4 in contact with the rolling brush 13 is constantly changing during the rolling process. At this time, the compression spring 16 pushes the slide bar 12 to move upward, so that the rolling brush 13 can always keep in contact with the inner wall of the rolling box 4, thereby improving the cleaning effect of the inner wall of the rolling box 4.

[0021] A semicircular shoe 18 is fixed to the top of the slide rod 12 , and slots are provided at both ends of the semicircular shoe 18 . Both ends of the roller brush 13 are rotatably connected to plug-in fixing seats 19 , which can be engaged with the slots at both ends of the semicircular shoe 18 .

[0022] The outer side of the semicircular tile support 18 is detachably connected with an arc-shaped cleaning plate 20, and 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 semicircular tile support 18, and the comb teeth 21 can be inserted into the through holes. When the arc-shaped cleaning plate 20 is fitted with the semicircular tile support 18, the ends of the comb teeth 21 can be inserted into the gap of the roller brush 13. When the roller brush 13 rolls along the inner wall of the rolling box 4, the fibers dropped from the fabric will adhere to the roller brush 13. In order to maintain the cleaning effect of the roller brush 13, when the roller brush 13 is in contact with the roller box 4, the roller brush 13 is pressed against the roller box 4. After the comb teeth 21 come into contact, the fibers adhered to the roller brush 13 will be torn off by the comb teeth 21 and trapped in the semicircular tile holder 18. When the test is completed, the roller brush 13 can be removed first, and then the arc cleaning plate 20 can be removed. When the arc cleaning plate 20 is separated from the semicircular tile holder 18, the comb teeth 21 are also pulled out from the through holes of the semicircular tile holder 18 at the same time. Therefore, no fibers will remain on the comb teeth 21, and the fibers dropped on the fabric will be blocked in the semicircular tile holder 18. At this time, the fibers remaining in the semicircular tile holder 18 can be cleaned.

[0023] The static elimination mechanism 9 includes a contact piece 14, one side of which is connected to the slide bar 12, and the other side of the contact piece 14 can fit with the inner wall of the rolling box 4. The static 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 slide bar 12, the connecting plate 23 is fixedly connected to one end of the connecting shaft 22, and the other end of the connecting shaft 22 is connected to the slide bar 12 through a torsion spring. The support frame 24 is fixed on the connecting plate 23. The contact piece 14 is a metal sheet, and the contact piece 14 is fixed on the support frame 24. The contact piece 14 contacts the inner wall of the rolling box 4, so that the charge accumulated in the rolling box 4 can be released through the contact piece 14.

[0024] The counterweight head 15 adopts a metal sphere structure. When the roller box 4 rotates, the test fabric 7 located inside the roller box 4 occasionally touches the metal sphere during movement. The charge accumulated on the test fabric 7 is released through the metal sphere, which has the effect of eliminating static electricity and avoids 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 supporting frame 24 are all made of metal and are connected to the ground wire to release the charge near the contact piece 14.

[0025] The roller brush 13 is made of a steel wire roller brush 13 or a carbon fiber roller brush 13 , so that the roller brush 13 can conduct electricity, thereby further preventing the generation of static electricity.
