[0002] Shoes include soles and uppers. For special occasions, there are certain requirements for wear resistance of the uppers. For example, in construction sites, mountaineering, hiking and other application occasions, the wear resistance of the uppers is significantly different due to different materials. According to the usage scenarios of the shoes, it is an urgent problem to reasonably select the upper materials that meet the wear resistance requirements.

[0003] Therefore, during the development of shoes, we need to test various upper materials to meet the wear resistance requirements of the upper at a lower cost.

[0004] Therefore, we designed a shoe fabric wear resistance testing device that can quickly perform wear resistance tests on a variety of different fabrics and improve test efficiency. Utility Model Content

[0035] like Figure 1 and Figure 2 The wear resistance testing device for shoe fabric shown in the figure includes a base 1, a material tray device 2 rotatably installed above the base 1, and a servo motor 3 installed on the base 1 and driving the material tray device 2 to rotate. A bracket system 4 is installed through the base 1, and a grinding motor 5 is installed through the bracket system 4. The output end of the grinding motor 5 is provided with a grinding head 6 corresponding to the material tray device 2, and the grinding head 6 is detachable. The material of the grinding head 6 is selected according to needs. A braking device 7 is also provided on the top of the base 1.

[0036] See also Figures 1 to 5As shown, the material tray device 2 includes a material tray 21, a groove 22 is arranged on the top of the material tray 21, a plurality of convex plates 23 are arranged in an annular manner at the bottom of the groove 22, a bolt 24 is arranged at the axis of the groove 22, a pressure plate 25 is detachably installed in the groove 22, the pressure plate 25 has a circular hole 26 corresponding to the convex plate 23, the aperture of the circular hole 26 is larger than the diameter of the convex plate 23, the bolt 24 passes through the pressure plate 25 upwards and is matched with a nut 27, and the bottom of the material tray 21 is fixed with a screw. A central shaft 28 is arranged at the axis center of the base 1, and a shaft seat 121 is arranged on the top of the base 1. The central shaft 28 is inserted into the shaft seat 121, and a bearing (not shown) is matched between the central shaft 28 and the shaft seat 121. A brake ring 29 matched with the braking device 7 is clamped on the outer wall of the material tray 21, and a driven gear 210 matched with the servo motor 3 is arranged below the material tray 21, and a driving gear 310 matched with the driven gear 210 is installed at the output end of the servo motor 3.

[0037] In the above technical solution, when testing the fabric, the fabric is first cut into a circle, and the diameter of the obtained fabric piece needs to be larger than the aperture of the circular hole 26. The fabric piece is laid on the convex plate 23, and then the pressure plate 25 is assembled. The pressure plate 25 acts on the fabric piece so that the fabric piece is effectively laid flat on the surface of the convex plate after being tensioned. The convex plate 25 protrudes to the outside of the circular hole 26.

[0038] See also Figure 2 As shown, the support system 4 includes a "Z"-shaped support 41, the grinding motor 5 is installed on the top of the support 41, and the output shaft of the grinding motor 5 passes downward through the support 41 and is connected to the grinding head 6. A guide rod 131 is installed on the top of the base 1, and the guide rod 131 passes through the support 41. The support 41 slides vertically along the guide rod 131. An electric push rod 141 is installed on the top of the base 1, and a limiting plate 151 is installed at the output end of the electric push rod 141. The limiting plate 151 is supported on the bottom of the support 41, and an extension rod 161 is arranged at the axis of the limiting plate 151. The extension rod 161 passes upward through the support 51 and cooperates with a limiting cap 171. A spring 181 is sleeved on the extension rod 161, and the spring 181 acts between the limiting cap 171 and the support 41.

[0039] In the above technical solution, the grinding motor 5 is supported by the bracket 41. As the electric push rod 141 retracts, the bracket 41 moves downward until the grinding head 6 contacts the fabric piece. At this time, the electric push rod 141 continues to retract, causing the spring 181 to be compressed. At this time, the downward pressure of the bracket 41 increases, and the pressure of the grinding head 6 on the fabric to be polished increases.

[0040] According to the test requirements, the downward pressure of the grinding head 6 is adjusted to meet the wear resistance test of the fabric under different pressure conditions.

[0041] For example, fabric pieces of the same material can be installed on multiple bosses. During the test, each fabric piece is subjected to a different grinding downforce, which can then be compared to determine at what intensity the fabric piece will reach its wear resistance limit.

[0042] See also Figure 6 As shown, the braking device 7 includes a first bracket 71, and a first electric push rod 72 is fixedly installed through the first bracket 71, and a brake plate 73 is installed at the output end of the first electric push rod 72. The brake plate 73 is arc-shaped, and a brake pad 74 is detachably installed on the inner wall of the brake plate 73. The brake pad 74 cooperates with the brake ring 29.

[0043] The above technical solution is mainly to avoid the rotation of the material tray caused by the rotation of the grinding head.

[0044] There are 6 convex discs distributed in an annular manner.

[0045] The utility model further comprises a controller (not shown), wherein the controller is connected to the servo motor, the grinding motor, the electric push rod and the first electric push rod.

[0046] The wear resistance test method for the upper is as follows:

[0047] First, load a variety of fabrics onto the tray device, and then set the descending parameters of the electric push rod through the controller so that the stroke of the electric push rod is consistent each time it descends.

[0048] Start the equipment, the controller controls the servo motor to rotate a fixed number of circles, at this time the material tray rotates a fixed angle, so that one of the convex plates is opposite to the grinding head, at this time the controller controls the first electric push rod to push out, so that the brake pad and the brake ring contact to generate braking force, at this time the material tray angle is fixed. Then the controller starts the grinding motor, so that the grinding head starts to rotate, and then the controller controls the electric push rod to retract, so that the height of the grinding head drops until it contacts the material being tested.

[0049] The controller sets the grinding time after the grinding head is in place. When the set grinding time is reached, the electric push rod returns first, and then the first electric push rod returns. At this time, the material tray can rotate, and the servo motor drives the material tray to rotate a fixed angle so that the next convex plate is opposite to the grinding head, and the next time starts.

[0050] Until all the upper materials loaded on the convex discs have been tested.

[0051] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that are not conceived through creative work should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope defined in the claims.
