[0002] Fabric performance testing refers to testing and evaluating the various physical, chemical and mechanical properties of fabrics to ensure that the fabrics meet specific standards and requirements. Fabric performance testing is crucial to the quality control of textiles and can help manufacturers, retailers and consumers understand the characteristics and scope of application of fabrics. It includes a variety of tests such as air permeability, moisture absorption, elasticity, antibacterial and pilling resistance. Among them, fabric pilling performance testing is an important textile quality test used to evaluate the tendency of fabrics to form small balls during normal use and wearing. Pilling not only affects the appearance of the fabric, but may also affect its feel and durability. When measuring the fabric, the existing measuring device has a fixed degree of fit of the fabric grinding disc.

However, in the actual wearing process of fabrics, the friction strength is inconsistent in different working environments, different people and different parts. The friction conditions in actual situations are the superposition of multiple situations.

The reciprocating screw 10 is threadedly connected with the telescopic end of the second elastic push rod 7. The first gear 11 drives the telescopic movement of the second elastic push rod 7 through the reciprocating screw 10 to perform linear reciprocating sliding along its fixed part, so that the hydraulic oil in the fixed part of the second elastic push rod 7 and the hydraulic oil in the first elastic push rod 5 circulate, periodically changing the degree of fit between the friction disk 3 and the fabric to simulate the different degrees of friction between the fabric and external objects in real life, so as to improve the accuracy of the fabric pilling test.

The second gear 201 is meshed with the rack 12. The telescopic end of the left electric push rod 2 drives the rack 12 to perform linear reciprocating motion, and drives the second gear 201 to alternately rotate forward and reverse. The left side of the base 1 is rotatably connected to a fourth gear 202. The second gear 201 is rotatably connected to the fourth gear 202. The fourth gear 202 is located directly below the second gear 201. The base 1 is rotatably connected to two rotating tables 203 symmetrically distributed on the left and right centers. The two rotating tables 203 symmetrically distributed on the left and right centers are both fixedly connected to a fifth gear 204.

[0035] See also Figure 4 The one-way component includes three one-way blocks 207 in an annular array, and the three one-way blocks 207 in the annular array are all hinged on the fourth gear 202. A first elastic element 208 is arranged between the three one-way blocks 207 in the annular array and the fourth gear 202. The first elastic element 208 is a spring. The first elastic element 208 is used to drive the adjacent one-way blocks 207 to reset. A right-angled triangular groove in an annular array is arranged on the lower side of the second gear 201. The one-way block 207 is provided with an inclined surface that fits the right-angled triangular groove, and the one-way block 207 fits the right-angled triangular groove of the fourth gear 202. The three one-way blocks 207 in the annular array are all squeezed and matched with the right-angled triangular groove of the annular array, which is used to make the second gear 201 drive the fourth gear 202 to rotate in one direction, so as to avoid the reciprocating screw 10 rotating alternately due to the linear reciprocating motion of the rack 12, and the hydraulic oil in the fixed part of the second elastic push rod 7 cannot be pressed into the fixed part of the first elastic push rod 5.

[0036] See also Figure 2 and Figure 5The limit assembly includes a fixed shaft 301, which is fixedly connected to the base 1, and the central axis of the fixed shaft 301 is parallel to the central axis of the sliding shaft 205. A sliding ring 302 is fixedly connected to the top of the sliding shaft 205. The sliding ring 302 is slidably connected to the fixed shaft 301. The sliding ring 302 is threadedly connected with a bolt 303, and the bolt 303 is squeezed and matched with the fixed shaft 301. After the sliding shaft 205 adjusts the position of the rotating ring 206, the bolt 303 contacts the fixed shaft 301 along the sliding ring 302 and squeezes each other to lock the sliding shaft 205.

[0037] See also Figure 1 and Figure 6 The adjustment component includes an adjustment piston shaft 401, which is sealed and slidably connected to the adjustment cylinder 8. The adjustment piston shaft 401 slides to extract the hydraulic oil in the fixed part of the first elastic push rod 5 or injects hydraulic oil into it, so that the telescopic end of the first elastic push rod 5 drives the fixed platform 6 to move up and down, which is convenient for the installation of the fabric and at the same time adjusts the initial fitting strength between the fabric and the friction disk 3. The outer side of the adjustment piston shaft 401 is slidably connected with a pin shaft 402. The adjustment piston shaft 401 is provided with a linear array of locking holes 403. The central axis of the locking hole 403 is parallel to the central axis of the pin shaft 402. The locking holes 403 in the linear array are all limitedly matched with the pin shaft 402. The pin shaft 402 is inserted into the adjacent locking hole 403 to lock the adjustment piston shaft 401.

[0038] See also Figure 7 and Figure 8 The fixing assembly includes a fixing ring 501, which is slidably connected to the fixing platform 6 through a connecting piece, and the two are in contact and cooperate. The fabric is placed between the fixing ring 501 and the fixing platform 6, and then the fixing ring 501 is slid upward to make the fabric fit the outside of the fixing platform 6 to form a fixation. The fixing ring 501 is slidably connected with two mirror-distributed plug shafts 502, and a second elastic element 503 is arranged between the mirror-distributed plug shafts 502 and the fixing ring 501. The second elastic element 503 is a tension spring, which is used to drive the adjacent plug shafts 502 to reset. The second elastic element 503 is initially in a stretched state. The fixing platform 6 is provided with two mirror-distributed limiting holes 504, and the mirror-distributed plug shafts 502 are respectively limited and cooperated with the adjacent limiting holes 504, so that the plug shaft 502 enters the adjacent limiting holes 504 to fix the fabric.

[0039] When the fabric needs to be tested for pilling, the staff places the test sample of the fabric between the fixing ring 501 and the fixing table 6, and then slides the fixing ring 501 upwards. At this time, the fixing ring 501 drives the fabric to move upward synchronously, so that the fixing ring 501 drives the fabric to contact the fixing table 6, and at the same time, the fixing ring 501 drives the two mirror-distributed plug shafts 502 to move upward synchronously, and this is done until the fixing ring 501 drives the two mirror-distributed plug shafts 502 to move to the same height of the limiting holes 504. At this time, the two mirror-distributed second elastic elements 503 respectively drive the adjacent plug shafts 502 to move into the adjacent limiting holes 504, and fix the fixing ring 501 to the fixing table 6. At this time, the fabric is fixed.

[0040] When the fabric is fixed, the staff pushes the adjusting piston shaft 401, and the adjusting piston shaft 401 pushes the hydraulic oil in the adjusting cylinder 8 along the connecting hose 9 into the fixed part of the first elastic push rod 5, and the hydraulic oil in the fixed part of the first elastic push rod 5 pushes its telescopic end to move downward, until the fixed platform 6 drives the fabric thereon to contact the bottom friction plate 3, and adjusts the distance between the fixed platform 6 and the friction plate 3, so that the fitting force between the fabric and the friction plate 3 reaches the required degree, and then the staff inserts the pin shaft 402 into the locking hole 403 adjacent to the adjusting piston shaft 401 to lock the adjusting piston shaft 401.

[0041] When the adjustment piston shaft 401 is fixed, the staff then pushes the sliding shaft 205, and the sliding shaft 205 drives the rotating ring 206 to move synchronously, so that the rotating ring 206 is separated from the two rotating tables 203 symmetrically distributed in the center, so that the rotating table 203 cannot drive the first gear 11 to rotate. At this time, it is the first working mode of the device. The bonding strength between the fabric and the friction disk 3 is always consistent, and the pilling condition of the fabric under the fixed bonding strength can be detected. When the sliding shaft 205 drives the rotating ring 206 to contact the two rotating tables 203 symmetrically distributed in the center, it is the second working mode of the device. The bonding strength between the fabric and the friction disk 3 is in a periodic change state, and the speed of change is determined by the bonding strength between the rotating ring 206 and the two rotating tables. 203 is determined by the fitting position. When the rotating ring 206 is located below the two rotating tables 203, the fitting strength between the fabric and the friction disk 3 changes slowly. On the contrary, when the rotating ring 206 is located above the two rotating tables 203, the fitting strength between the fabric and the friction disk 3 changes quickly. When the staff adjusts the working mode, the sliding shaft 205 drives the sliding ring 302 thereon to slide synchronously along the fixed shaft 301. When the staff completes the mode adjustment, the staff rotates the bolt 303, and the bolt 303 moves inward along the sliding ring 302 until the bolt 303 contacts the fixed shaft 301 and squeezes each other to fix the sliding ring 302, thereby locking the sliding shaft 205 to the adjusted position.

[0042] When the sliding shaft 205 is locked, the second working mode is taken as an example here, and the staff turns on the two electric push rods 2. The telescopic ends of the two electric push rods 2 respectively drive the friction disc 3 and the fixed frame 4 thereon to perform linear reciprocating motion, so that the fixed frame 4 drives the fabric thereon to rub against the friction disc 3 through the fixed platform 6. At the same time, when the fixed frame 4 performs linear reciprocating motion, it drives the rack 12 thereon to move synchronously, and the rack 12 drives the second gear 201 to rotate alternately forward and reversely. The second gear 201 alternately rotates forward and reversely to drive the right-angled grooves of the annular array of its inner ring 601 to rotate synchronously. When the second gear 201 rotates counterclockwise (based on the top view), it cannot push the annular array. The three one-way blocks 207 of the second gear 201 rotate synchronously. When the second gear 201 rotates clockwise, the three one-way blocks 207 of the annular array rotate synchronously. At this time, the three one-way blocks 207 of the annular array drive the fourth gear 202 to rotate synchronously, converting the positive and negative rotation of the second gear 201 into the periodic rotation of the fourth gear 202. The fourth gear 202 drives the adjacent fifth gear 204 to rotate, and the fifth gear 204 drives the adjacent rotating platform 203 to rotate. The rotating platform 203 drives another rotating platform 203 to rotate synchronously through the rotating ring 206. The rotating platform 203 drives the adjacent fifth gear 204 to rotate, so that the fifth gear 204 is driven by the first gear 11. The reciprocating screw 10 rotates (the first working mode, since the swivel 206 and the two rotating tables 203 are separated, it cannot drive the reciprocating screw 10 to rotate), and the reciprocating screw 10 drives the telescopic end of the second elastic push rod 7 to move inward along its fixed part. At this time, the hydraulic oil in the fixed part of the second elastic push rod 7 enters the adjacent connecting hose 9 under the thrust of the telescopic end, and then the connecting hose 9 enters another connecting hose 9 through the adjusting cylinder 8, and finally enters the fixed part of the first elastic push rod 5. At this time, the hydraulic oil in the fixed part of the first elastic push rod 5 pushes its telescopic end to move downward, and the telescopic end of the first elastic push rod 5 drives the fixed table 6 to move downward, changing the fixed table 6 and the friction The distance between the rubbing discs 3 is increased, and the fitting strength of the two is increased until the telescopic end of the second elastic push rod 7 moves to the bottom of the reciprocating screw 10. At this time, the reciprocating screw 10 drives the telescopic end of the second elastic push rod 7 to start moving upward. At this time, the hydraulic oil in the fixed part of the first elastic push rod 5 flows back to the fixed part of the second elastic push rod 7, so that the distance between the fixed platform 6 and the friction disc 3 is reset, and the fitting degree of the friction disc 3 and the fabric is reduced. This cycle is repeated until the pilling test of the fabric is completed. By periodically changing the fitting degree of the friction disc 3 and the fabric, the different degrees of friction between the fabric and external objects in real life can be simulated to improve the accuracy of the fabric pilling test.

[0043] When the pilling test of the fabric is completed, the staff closes the two electric push rods 2, then pulls out the pin 402, releases the limit of the pin 402 on the adjusting piston shaft 401, and then pulls the adjusting piston shaft 401, so that the adjusting piston shaft 401 extracts the hydraulic oil in the fixing part of the first elastic push rod 5 through the adjusting cylinder 8 and the connecting hose 9, so that the telescopic end of the first elastic push rod 5 drives the fixing platform 6 to separate from the friction disk 3, and then the staff pulls the two mirror-distributed plug shafts 502, and at the same time the two second elastic elements 503 are stretched to separate the plug shaft 502 from the adjacent limiting holes 504, and then the staff drives the fixing ring 501 to slide downward to separate the fabric from the fixing platform 6, then remove the fabric and observe its pilling condition, and repeat the above steps when the fabric is subjected to the pilling test again.

[0044] In this embodiment, the fixing ring 501 and the fixing platform 6 fix the fabric, but this is limited to Embodiment 1. In other subsequent embodiments, a gap is left between the fixing ring 501 and the fixing platform 6, and the fabric cannot be directly fixed. Please refer to the specific description in the subsequent embodiments.

The fixed ring 501 drives the inner ring 601 to rise, and the inner ring 601 drives the airbag 602 to move synchronously, so that the airbag 602 drives the fabric to be gradually stretched and flattened by the uniform upward and circumferential force, and the external tension of the fabric remains consistent, avoiding different tensions at local positions of the fabric, thereby reducing the accuracy of the fabric pilling test. The fixed platform 6 is provided with a maintaining component for maintaining the squeezing force of the airbag 602 on the fabric.

A fourth elastic element 607 is arranged between the first fixed cylinder 605 and the first piston shaft 606. The fourth elastic element 607 is a tension spring. The fourth elastic element 607 is used to drive the first piston shaft 606 to reset. A first hose 608 is fixedly connected between the first fixed cylinder 605 and the airbag 602. The first hose 608 runs through The inner ring 601 and the first closed cavity are connected to the airbag 602 through the first hose 608, so that the gas in the airbag 602 and the gas in the first closed cavity flow mutually, the first piston shaft 606 is in contact and cooperated with the inner ring 601, and the inner ring 601 drives the first piston shaft 606 to move synchronously. By extracting the gas in the airbag 602 when the fabric is stretched, the squeezing force between the airbag 602 and the fixed platform is kept consistent, the sliding wear of the airbag is reduced, and the service life of the airbag is increased. The fixed platform 6 is provided with a fastening component for increasing the fixing force of the airbag 602 on the fabric.

[0047] See also Figure 7 , Fig. 9 and Fig.11 The fastening assembly includes a second fixed cylinder 609, which is fixedly connected to the right front side of the fixed platform 6. The second fixed cylinder 609 is sealed and slidably connected to the second piston shaft 610, and the two cooperate to form a second closed cavity. The bottom of the second piston shaft 610 is located above the two blocks 604 distributed in a mirror image. The second piston shaft 610 is in contact with the fixing ring 501. The fixing ring 501 rises and drives the second piston shaft 610 to move upward synchronously. A fifth elastic element 611 is arranged between the second fixed cylinder 609 and the second piston shaft 610. The fifth elastic element 611 is a tension spring. The fifth elastic element 611 is used to drive the second movable The plug shaft 610 is reset, and the elastic coefficient of the fifth elastic element 611 is greater than the elastic coefficient of the fourth elastic element 607, so that when the first piston shaft 606 extracts the gas in the airbag 602, the second piston shaft 610 will not slide along the second fixed cylinder 609. A second hose 612 is fixedly connected between the second fixed cylinder 609 and the airbag 602. The second hose 612 passes through the inner ring 601. The second closed cavity is connected to the airbag 602 through the second hose 612, so that the gas in the second closed cavity flows into the airbag 602 to expand the airbag 602. The expansion of the airbag 602 squeezes the fabric to form a fixed shape to prevent the fabric from moving when sliding.

[0048] When the staff fixes the fabric, it is difficult to stretch the fabric evenly, resulting in different tensions at local locations of the fabric, and even wrinkles, which in turn affects the accuracy of the fabric pilling test. When the fabric is fixed, the staff places the fabric in the inner ring 601, so that the fabric is located between the inner ring 601 and the fixed platform 6, and the airbag 602 contacts the fabric. When the fixed ring 501 slides upward, the fixed ring 501 drives the inner ring 601 to move synchronously. At this time, the inner ring 601 drives the airbag 602 thereon to move synchronously. The airbag 602 moves step by step, and the fabric moves upward synchronously with the airbag 602, until the airbag 602 contacts the inclined surface at the bottom of the fixed platform 6 across the fabric. At this time, the inner ring 601 continues to move upward. At this time, the airbag 602 squeezes the fabric and stretches it upward along the inclined surface at the bottom of the fixed platform 6, so that the fabric is gradually stretched flat by the uniform upward and circumferential force, so that the external tension of the fabric remains consistent, until the fixed ring 501 drives the inner ring 601 to contact the two mirror-distributed blocks 604. At this time, the inner ring 601 is limited by the blocks 604 and cannot continue to move upward.

[0049] During the upward movement of the inner ring 601, the inner ring 601 drives the first piston shaft 606 to move upward synchronously, and the first piston shaft 606 slides along the first fixed cylinder 605. At the same time, the fourth elastic element 607 is stretched. At this time, the volume of the first closed cavity increases, so that the gas in the airbag 602 enters the first closed cavity, and the expansion degree of the airbag 602 is gradually reduced, so that the extrusion force between the airbag 602 and the fixed platform 6 is kept consistent, and the wear of the airbag 602 is reduced, so as to avoid that when the airbag 602 slides along the bottom inclined surface of the fixed platform 6, the bottom radius of the fixed platform 6 gradually increases, so that the extrusion force between the airbag 602 and the fixed platform 6 gradually increases, the wear of the airbag 602 is aggravated, and the service life of the airbag 602 is reduced.

[0050] When the inner ring 601 is limited by the block 604, the staff continues to drive the fixing ring 501 to move upward. At this time, the airbag 602 stops moving, but its fastening force on the fabric is too small and it is very easy to fall off during the friction process. At this time, the fixing ring 501 moves upward and contacts the second piston shaft 610, and drives the second piston shaft 610 to move upward. At the same time, the third elastic element 603 is compressed, so that the second piston shaft 610 slides upward along the second fixed cylinder 609, and at the same time, the fifth elastic element 611 is stretched. At this time, the volume of the second closed cavity is reduced, and the second piston shaft 610 pushes the gas in the second closed cavity along the second hose 612 into the airbag 602, so that the airbag 602 further expands and increases the fastening force of the airbag 602 on the fabric, until the fixing ring 501 drives the insertion shaft 502 to rise to the limiting hole 504, and then the staff inserts the insertion shaft 502 into the corresponding limiting hole 504, and the second elastic element 503 is reset. At this time, the fabric is fixed.

[0051] When the pilling test of the fabric is finished, the staff withdraws the insertion shaft 502, and the second elastic element 503 is stretched until the fixing ring 501 slides to the bottom. During this process, the fifth elastic element 611 is reset, and drives the second piston shaft 610 to reset, so that the gas in the airbag 602 flows back to the second closed cavity, so that the fixing ring 501 drives the inner ring 601 to reset synchronously, and the inner ring 601 is separated from the block 604. At the same time, the third elastic element 603 is reset, and the fourth elastic element 607 is reset, so that the gas in the first closed cavity gradually flows back to the airbag 602, so that the airbag 602 returns to the initial expansion degree, and then the fabric is removed. When the fabric needs to be fixed again, repeat the above steps.
