Description

Technical Field

[0001] The invention relates to the technical field of wear resistance testing of upper fabrics, in particular to a wear resistance testing device and a testing method for warp-knitted jacquard upper fabrics. Background Art

[0002] Warp knitted jacquard upper fabric is a fabric specially used for shoe uppers produced using jacquard technology. This fabric has both the basic characteristics of good dimensional stability, elasticity and strength brought by the warp knitting process, and the unique appearance effect given by the jacquard pattern.

[0003] After the production of warp knitted jacquard upper fabric is completed, in order to ensure the processing quality of the warp knitted jacquard upper fabric, it is necessary to test the wear resistance of the toe, heel and upper of the warp knitted jacquard upper fabric. During the test, the friction head is brought into contact with the surface of the test position and friction is generated. During the friction process, the counter records the number of frictions and the timer records the time. After the test, the wear condition of the sample is analyzed and evaluated through the observation and measurement system to obtain the wear resistance data of the fabric.

[0004] However, during the test, it is difficult for the existing test device to simulate the friction environment of the warp knitted jacquard upper during actual use. For example, during the start and sprint stages, the human body's movement direction is mainly forward horizontally. At this time, the force exerted by the foot on the ground is mainly forward pushing force and vertical support force. According to the force decomposition, most of the force is concentrated on the toe (forward pushing force during the start) and the heel (support force and backward friction force after the foot lands). In this case, since the direction of the force is mainly in the front-to-back direction, the lateral force component on both sides of the upper is relatively small. Secondly, when a large force is generated on both sides of the upper, such as turning or crossing an obstacle, the foot will have obvious lateral movement. When turning, the body tilts inward, the outside of the foot lands and bears most of the body weight. At this time, the main movement of the foot is inward twisting and support. In this case, the movement speed and force of the foot in the front-to-back direction will decrease. For this reason, we propose a wear resistance test device and a test method for warp knitted jacquard upper fabric. Summary of the invention

[0019] Preferably, a method for testing the wear resistance of a warp-knitted jacquard shoe upper fabric comprises the following steps:

[0020] S1: During the wear resistance test of the upper fabric body, the upper fabric body to be tested is placed on a template of a test bench. During the placement process, the first friction head and the second friction head are pressed against the inner side of the upper fabric body with a certain extrusion force;

[0021] S2: After the shoe upper fabric body is sheathed, the pressing plates on each set of limiting components are forced to move toward the outer side of the shoe upper fabric body after sheathing and resist each other through the extrusion component, and the shoe upper fabric body after sheathing is fixed on the template through the resisting and extruding effect between the pressing plates on each set of limiting components and the outer side of the shoe upper fabric body;

[0023] S4: During the friction treatment process, when it is necessary to simulate the friction scenes of the upper fabric body at the start and sprint stages, the first elastic component between the first mounting plate and the first connecting plate increases the extrusion force of the first friction head on the first connecting plate through transmission, so that the two groups of first friction heads are pressed against the toe and the heel with a greater extrusion force, simulating the friction scenes at the start and sprint stages;

[0024] S5: In the process of pushing the two sets of first U-shaped plates, the two sets of second U-shaped plates are forced to move closer to each other through the connecting transmission effect of the connecting plate. In the process of the two sets of second U-shaped plates moving closer to each other, the two sets of second mounting plates are forced to move closer to each other, thereby reducing the extrusion elastic force of the two sets of second elastic components on the two sets of second friction heads respectively, so that when the extrusion force of the two sets of first friction heads on the toe and the heel is increased, the extrusion force of the two sets of second friction heads on the uppers on both sides is simultaneously reduced, so as to simulate the real use scenario of the upper fabric body for testing;

[0025] S6: During the friction treatment process, when it is necessary to simulate the friction scene of the upper fabric body turning or crossing an obstacle, the diamond plate is respectively offset against the two sets of second U-shaped plates through transmission. During the offset process, the extrusion force of the second friction heads on the two sets of second connecting plates and the uppers on both sides is increased through transmission, and the extrusion force of the two sets of first elastic components on the two sets of first friction heads is reduced through the connecting transmission of the connecting plate, so that when the extrusion force of the two sets of second friction heads on the uppers on both sides is increased, the extrusion force of the two sets of first friction heads on the toe and the heel is simultaneously reduced, so as to simulate the real use scenario of the upper fabric body for testing;

[0026] S7: After the test is completed, the upper fabric body is removed, and the wear condition of the sample is analyzed and evaluated through observation and measurement system to obtain the wear resistance data of the upper fabric body.

[0027] Compared with the prior art, the present invention has the following beneficial effects:

Two groups of second test assemblies are arranged on the upper side of the test bench 101, for testing the wear resistance of the inner upper of the upper fabric body 104. An operating table 8 is fixed on the upper end of the test bench 101. The operating table 8 is provided with an adjustment component for adjusting the test pressure of the first test assembly and the second test assembly, and a control component for controlling the pressure between the first test assembly and the second test assembly during the adjustment process.

[0044] It should be noted here that: during the process of testing the wear resistance of the upper fabric body 104, the wear resistance of the inner toe, heel and uppers on both sides of the upper fabric body 104 is tested through the mutual cooperation of components such as the limit assembly, the first test assembly, the second test assembly, the adjustment assembly and the control component, and during the test, the upper fabric body 104 can be simulated to cope with different friction usage scenarios such as the starting and sprinting stages, turning or crossing obstacles, thereby improving the authenticity of the test.

[0045] A plurality of groups of position limiting components are arranged on the test bench 101 and are used to limit the position of the upper fabric body 104 after it is sleeved on the template 102, and each group of position limiting components is evenly distributed around the template 102;

[0046] It should be noted here that the limiting effect is ensured by using multiple sets of evenly distributed limiting components.

[0048] It should be noted here that: after the upper fabric body 104 is put on, the pressing plate 202 on each group of limiting components is forced to move toward the outer side of the upper fabric body 104 after the sleeve is completed and resist each other through the extrusion component. Through the resisting and extruding effect between the pressing plate 202 on each group of limiting components and the outer side of the upper fabric body 104, the upper fabric body 104 after the sleeve is fixed on the template 102.

[0049] The extrusion assembly includes a threaded sleeve 301 fixed on the support frame 201, a threaded rod 302 is threadedly engaged on the threaded sleeve 301, one end of the threaded rod 302 is fixed to one side of the pressing plate 202, and a rotating pin 303 for rotating the threaded rod 302 is fixed to the other end of the threaded rod 302;

[0050] It should be noted here that: the threaded rod 302 is driven to rotate by the rotating pin 303 , and during the rotation of the threaded rod 302 , the pressing plate 202 is moved by the mutual meshing transmission between the threaded rod 302 and the threaded sleeve 301 .

[0051] Preferably, the first test assembly includes a first mounting plate 401 disposed above the test bench 101, a first connecting plate 402 is disposed on one side of the first mounting plate 401, the first mounting plate 401 and the first connecting plate 402 are connected via a first elastic component, a first friction head 403 for auxiliary testing is rotatably connected to the first connecting plate 402, and a first motor 404 for driving the first friction head 403 is installed on the first connecting plate 402;

[0052] It should be noted that: the first friction head 403 is driven to rotate by the first motor 404, and because the first friction head 403 abuts against the toe or heel of the upper fabric body 104, the toe and heel of the upper fabric body 104 are rubbed by the rotation of the first friction head 403;

[0053] It is worth noting here that a counter for counting the number of rotations and a timer for timing the friction time are installed on the first connecting plate 402. The timer and the counter are conventional components in the friction test process. Their operation methods and working modes are regarded as prior art in this application and will not be elaborated on here.

[0054] Preferably, the first elastic component includes two groups of symmetrically arranged first sleeves 501 fixed to one side of the first mounting plate 401, a first slide bar 502 is slidably connected to the first sleeve 501, one end of the first slide bar 502 is fixed to the first connecting plate 402, and a first spring 503 is sleeved on the outer side of the first sleeve 501;

[0055] It should be noted here that: through multiple groups of first sleeves 501 and first slide rods 502, it is convenient to assist the telescopic connection between the first connecting plate 402 and the first mounting plate 401. When relative contraction occurs between the first connecting plate 402 and the first mounting plate 401, the first spring 503 is deformed by force to generate elastic force. Through the elastic force of the first spring 503, it is convenient to push the first friction head 403 on the first connecting plate 402 with elastic force.

[0056] Preferably, the second test assembly includes a second mounting plate 601 disposed above the test bench 101, a second connecting plate 602 is disposed on one side of the second mounting plate 601, the second mounting plate 601 and the second connecting plate 602 are connected via a second elastic component, a second friction head 603 for auxiliary testing is rotatably connected to the second connecting plate 602, and a second motor 604 for driving the second friction head 603 is installed on the second connecting plate 602;

[0057] It should be noted that: the second friction head 603 is driven to rotate by the second motor 604, and since the second friction head 603 is against the upper of the upper fabric body 104, the upper of the upper fabric body 104 is rubbed by the rotation of the second friction head 603;

[0058] It is worth noting here that a counter for counting the number of rotations and a timer for timing the friction time are installed on the second connecting plate 602. The timer and the counter are conventional components in the friction test process. Their operation methods and working modes are regarded as prior art in this application and will not be elaborated on here.

[0059] Preferably, the second elastic component includes two groups of symmetrically arranged second sleeves 701 fixed to one side of the second mounting plate 601, a second slide bar 702 is slidably connected to the second sleeve 701, one end of the second slide bar 702 is fixed to the second connecting plate 602, and a second spring 703 is sleeved on the outer side of the second sleeve 701;

[0060] It should be noted here that: through multiple groups of second sleeves 701 and second slide rods 702, the telescopic connection between the second connecting plate 602 and the second mounting plate 601 is assisted, and when the second connecting plate 602 and the second mounting plate 601 shrink relative to each other, the second spring 703 is deformed by force to generate elastic force, and the elastic force of the second spring 703 facilitates the elastic push of the second friction head 603 on the second connecting plate 602.

[0061] Preferably, the adjustment component includes two groups of first U-shaped plates 901 and two groups of second U-shaped plates 902 symmetrically arranged on the upper side of the operating table 8, a sliding component for slidingly connecting the first U-shaped plates 901 and the second U-shaped plates 902 is arranged on the operating table 8, the first U-shaped plates 901 and the first mounting plate 401 are connected and fixed by multiple groups of first connecting rods 903, the second U-shaped plates 902 and the second mounting plate 601 are connected and fixed by multiple groups of second connecting rods 904, and a pushing component for pushing the two groups of first U-shaped plates 901 and the second U-shaped plates 902 against each other is arranged on the operating table 8;

[0062] It should be noted here that: through the pushing component, the two groups of first U-shaped plates 901 are pushed to move away from each other under force. During the movement of the two groups of first U-shaped plates 901, the first mounting plate 401 is pushed to move under force through the connecting action of the first connecting rod 903. Because the front ends of the first friction heads 403 on the two groups of first connecting plates 402 are respectively limited by the toe and the heel of the shoe, the movement of the first mounting plate 401 increases the extrusion and pushing force of the first elastic force component between the first mounting plate 401 and the first connecting plate 402 on the first connecting plate 402, so that the two groups of first friction heads 403 are offset against the toe and the heel of the shoe with a greater extrusion force, and the diamond plates 1002 are respectively offset against the two groups of second U-shaped plates 902. When offsetting, the extrusion force of the second friction heads 603 on the two groups of second connecting plates 602 on the uppers on both sides is increased through transmission and the connecting transmission action of the connecting plate 12.

[0063] Preferably, the pushing assembly includes a mounting shaft 1001 rotatably connected to the operating table 8, the template 102 and the test table 101, the mounting shaft 1001 is centrally arranged between the two groups of first U-shaped plates 901 and the two groups of second U-shaped plates 902, a diamond plate 1002 is fixed on the mounting shaft 1001 for simultaneously pushing the two groups of first U-shaped plates 901 or the second U-shaped plates 902 against each other, and a third motor 1003 for driving the mounting shaft 1001 is installed at the lower end of the test table 101;

[0064] It should be noted here that: the third motor 1003 drives the diamond plate 1002 on the mounting shaft 1001 to rotate. During the rotation of the diamond plate 1002, the diamond plate 1002 is abutted against and pushed by the two groups of first U-shaped plates 901 or the two groups of second U-shaped plates 902.

[0065] Preferably, the control member includes a connecting plate 12 disposed between the adjacent first U-shaped plate 901 and the second U-shaped plate 902, and the two ends of the connecting plate 12 are rotatably connected to the first U-shaped plate 901 and the second U-shaped plate 902 respectively;

[0066] It should be noted here that: during the movement of the first U-shaped plate 901 , the second U-shaped plate 902 is driven to move through the connecting transmission effect of the connecting plate 12 .

[0067] Preferably, the sliding assembly includes a plurality of groups of T-slots 1101 opened at the upper end of the operating table 8, and T-blocks 1102 are fixed at the lower ends of the first U-shaped plate 901 and the second U-shaped plate 902, and the T-blocks 1102 are slidably connected to the T-slots 1101;

[0068] It should be noted here that the T-slot 1101 and the T-block 1102 facilitate the movement guidance of the first U-shaped plate 901 and the second U-shaped plate 902 after being subjected to force.

[0069] In this scheme: A method for testing the wear resistance of warp-knitted jacquard shoe upper fabric comprises the following steps:

[0070] S1: During the wear resistance test of the upper fabric body 104, the upper fabric body 104 to be tested is sleeved on the template 102 of the test bench 101. During the sleeve process, the inner side of the upper fabric body 104 is respectively abutted against the ends of the first friction head 403 and the second friction head 603 of the two groups of the first test assembly and the second test assembly. During the abutment process, the first friction head 403 and the second friction head 603 are pushed to shrink under the force and, through the elastic force of the first elastic assembly and the second elastic assembly, the first friction head 403 and the second friction head 603 are pushed to abut against the inner side of the upper fabric body 104 with a certain extrusion force;

[0071] S2: After the upper fabric body 104 is sleeved, the pressing plate 202 on each group of limiting components is forced to move toward the outer side of the sleeved upper fabric body 104 and resist each other through the pressing assembly, and the sleeved upper fabric body 104 is fixed on the template 102 through the pressing action of the pressing plate 202 on each group of limiting components and the outer side of the upper fabric body 104;

[0072] S3: In the process of fitting and fixing the upper fabric body 104, the first friction heads 403 on the two groups of first test components are respectively against the toe and the heel of the inner side of the upper fabric body 104, and the second friction heads 603 on the two groups of second test components are respectively against the uppers on both sides of the inner side of the upper fabric body 104. After the upper fabric body 104 is fitted and fixed, the two groups of first friction heads 403 and the second friction heads 603 are driven to rotate. Since the front ends of the two groups of first friction heads 403 are respectively against the toe and the heel of the upper fabric body 104 and the two groups of second friction heads 603 are respectively against the uppers on the inner side of the upper fabric body 104, the toe, the heel and the uppers on both sides of the upper fabric body 104 are rubbed by the rotation of the first friction heads 403 and the second friction heads 603;

[0073] S4: During the friction treatment process, when it is necessary to simulate the friction scenes of the upper fabric body 104 at the start and sprint stages, the third motor 1003 is used to drive the diamond plate 1002 on the mounting shaft 1001 to rotate. During the rotation of the diamond plate 1002, the diamond plate 1002 is made to abut against the two groups of first U-shaped plates 901. During the abutment process, the two groups of first U-shaped plates 901 are pushed to move away from each other. During the movement of the two groups of first U-shaped plates 901, the first connecting rod 90 3, the first mounting plate 401 is pushed to move under force, because the front ends of the first friction heads 403 on the two groups of first connecting plates 402 are respectively pressed against the toe and the heel of the shoe, and the first mounting plate 401 moves, the first elastic component between the first mounting plate 401 and the first connecting plate 402 increases the extrusion force of the first friction head 403 on the first connecting plate 402, so that the two groups of first friction heads 403 are pressed against the toe and the heel of the shoe with a greater extrusion force, simulating the friction scenes in the starting and sprinting stages;

[0074] S5: In the process of pushing the two groups of first U-shaped plates 901, the two groups of second U-shaped plates 902 are forced to move closer to each other through the connecting transmission effect of the connecting plate 12. In the process of the two groups of second U-shaped plates 902 moving closer to each other, the two groups of second mounting plates 601 are forced to move closer to each other, thereby reducing the squeezing elastic force of the two groups of second elastic components on the two groups of second friction heads 603, respectively, so that when the squeezing force of the two groups of first friction heads 403 on the toe and the heel is increased, the squeezing force of the two groups of second friction heads 603 on the uppers on both sides is simultaneously reduced, so as to simulate the real use scenario of the upper fabric body 104 for testing;

[0075] S6: During the friction treatment process, when it is necessary to simulate the friction scene of the upper fabric body 104 turning or crossing an obstacle, the diamond plate 1002 is respectively offset against the two groups of second U-shaped plates 902 through transmission. During the offset process, the extrusion pressure of the second friction heads 603 on the two groups of second connecting plates 602 and the uppers on both sides is increased through transmission, and the extrusion pressure of the two groups of first elastic components on the two groups of first friction heads 403 is reduced through the connecting transmission effect of the connecting plate 12, so that when the extrusion pressure of the two groups of second friction heads 603 and the uppers on both sides is increased, the extrusion pressure of the two groups of first friction heads 403 and the toe and heel are simultaneously reduced, so as to simulate the real use scenario of the upper fabric body 104 for testing;

[0076] S7: After the test is completed, the upper fabric body 104 is removed, and the wear condition of the sample is analyzed and evaluated through the observation and measurement system to obtain the wear resistance data of the upper fabric body 104.
