A moving mechanism for the slider is arranged at the upper end of the U-shaped frame.

[0006] Furthermore, the moving mechanism includes a support block and a fourth cylinder; support blocks are fixedly connected to the left and right edges of the upper end of the U-shaped frame 1. The upper end of the support block is fixedly connected with a fourth cylinder.

Specific embodiments

[0023] The present utility model will be further described below in conjunction with the drawings and embodiments.

[0024] Embodiment 1: Please refer to Figures 1 - 5 , a clothing fabric abrasion resistance testing device, comprising a U-shaped frame 1; two vertical frames 2 that are symmetric with respect to the center of the U-shaped frame 1 are fixedly connected to the upper end of the U-shaped frame 1. An upper pull mechanism is provided on the vertical frame 2. The lower end of the upper pull mechanism is fixedly connected to an upper pull block 3. The middle part of the inner wall of the U-shaped frame 1 is fixedly connected to a bearing plate 5. A lower pull mechanism is provided on the upper end of the bearing plate 5.

Both the upper pull block 3 and the lower pull block 6 are U-shaped. The upper pull block 3 has an opening downward, and the lower pull block 6 has an opening upward. A first bolt 4 is threadedly installed through one side of the upper pull block 3, and a second bolt 7 is threadedly installed through one side of the lower pull block 6. The side walls of the first bolt 4 and the second bolt 7 on the same side are jointly sleeved with an annular fabric 13. A third cylinder 10 is fixedly connected to the bottom surface of the inner wall of the U-shaped frame 1. The upper end of the output shaft of the third cylinder 10 is fixedly connected to a lifting block 11. Friction blocks 12 are fixedly connected to both the left and right ends of the lifting block 11. The end of the friction block 12 away from the lifting block 11 is in contact with the end of the annular fabric 13 close to the lifting block 11. A slider 8 is slidably provided on the inner wall of the vertical frame 2. An electric heating block 9 is fixedly connected to the end of the slider 8 close to the lifting block 11. A moving mechanism for the slider 8 is provided at the upper end of the U-shaped frame 1.

[0025] Put the annular fabric 13 on the side walls of the first bolt 4 and the second bolt 7, then threadedly install the first bolt 4 on the upper pulling block 3 and the second bolt 7 on the lower pulling block 6. Turn on the upper pulling mechanism to make the upper pulling block 3 move upward, and turn on the lower pulling mechanism to make the lower pulling block 6 move downward, so as to straighten the annular fabric 13. Turn on the electric heating block 9 to heat the outside of the annular fabric 13, and turn on the third cylinder 10 to make the lifting block 11 move in the vertical direction, then the friction block 12 will rub against the annular fabric 13, and the friction detection of two annular fabrics 13 of the same type can be carried out simultaneously. By observing the wear degree of the annular fabric 13 within a set time, the wear resistance of the fabric can be quickly detected.

[0026] Please refer to Figure 1 and Figure 3 In this embodiment, the upper pulling mechanism includes a first fixing frame 21 and a first cylinder 22; the upper end of the vertical frame 2 is fixedly connected with the first fixing frame 21, the inner wall of the first fixing frame 21 is fixedly connected with the first cylinder 22, and the lower end of the output shaft of the first cylinder 22 is fixedly connected to the upper end of the upper pulling block 3. By turning on the first cylinder 22 to drive the upper pulling block 3, it is convenient to control the movement of the upper pulling block 3 in the vertical direction.

[0027] Please refer to Figure 1 and Figure 5 In this embodiment, the friction block 12 is T-shaped, and the friction block 12 and the fourth cylinder 16 are at the same height. The T-shaped friction block 12 increases the contact area with the fabric and improves the friction effect. In addition, the friction block 12 and the fourth cylinder 16 being at the same height is beneficial to subsequent impact detection.

[0028] Please refer to Figure 1 In this embodiment, a groove is formed at one end of the slider 8 close to the lifting block 11, and the electric heating block 9 is located on the inner wall of the groove. The design of the groove can protect the electric heating block 9, and at the same time make the electric heating block 9 closer to the annular fabric 13, with better heating effect and without affecting the impact test of the slider 8 on the annular fabric 13.

[0029] Please refer to Figure 1 and Figure 4 In this embodiment, the lower pulling mechanism includes a second fixing frame 51 and a second cylinder 52; two second fixing frames 51 are fixedly connected to the upper end of the bearing plate 5, the inner wall of the second fixing frame 51 is fixedly connected with the second cylinder 52, the two second cylinders 52 are symmetric with respect to the lifting block 11, and the upper end of the output shaft of the second cylinder 52 is fixedly connected to the lower end of the lower pulling block 6. Turning on the second cylinder 52 can stably pull down the lower pulling block 6, ensure uniform force on the annular fabric 13, and improve the accuracy of the test.

[0030] Please refer to Figure 1 and Figure 5, in this embodiment, a limit frame 14 is fixedly connected to the center of the upper end of the bearing plate 5, and the lifting block 11 is slidably arranged on the inner wall of the limit frame 14. By providing the limit frame 14, the moving path of the lifting block 11 can be restricted to ensure its vertical movement, making the friction between the friction block 12 and the annular fabric 13 more stable and improving the detection accuracy.

[0031] Please refer to Figure 1 and Figure 2 , in this embodiment, the middle parts of the first bolt 4 and the second bolt 7 are both smooth sections. The setting of the smooth sections facilitates the sleeving of the annular fabric 13, reduces the damage to the fabric during the installation process, and does not affect the stability of the relative position between the fabric and the bolts during testing.

[0032] Embodiment 2: Please refer to Figure 5 , on the basis of Embodiment 1, the present application provides a technical solution: The moving mechanism includes a support block 15 and a fourth cylinder 16; Support blocks 15 are fixedly connected to the left and right edges of the upper end of the U-shaped frame 1, a fourth cylinder 16 is fixedly connected to the upper end of the support block 15, the output shaft of the fourth cylinder 16 faces the lifting block 11, and the output shaft of the fourth cylinder 16 is fixedly connected to the end of the slider 8 away from the lifting block 11. By turning on the fourth cylinder 16 to control the movement of the slider 8 through the fourth cylinder 16, the distance between the slider 8 and the annular fabric 13 can be adjusted, thereby improving the heating effect on the annular fabric 13.

[0033] Embodiment 3: Please refer to Figure 5 , on the basis of Embodiment 1 and Embodiment 2, the present application provides a technical solution: The annular fabric 13 is tightened by using the upward pulling mechanism and the downward pulling mechanism, and then the fourth cylinder 16 is turned on to make the slider 8 move towards the lifting block 11. By using the reciprocating impact of the slider 8 on the tightened annular fabric 13, the wear condition of the end of the annular fabric 13 close to the slider 8 can be observed, improving the detection of the annular fabric 13.

[0034] Working principle: The annular fabric 13 is sleeved on the middle parts of the smooth sections of the first bolt 4 and the second bolt 7. By rotating the first bolt 4 and the second bolt 7, the first bolt 4 is threadedly installed on the upward pulling block 3, and the second bolt 7 is threadedly installed on the downward pulling block 6;

[0035] Subsequently, start the first cylinder 22 of the upward pulling mechanism to drive the upward pulling block 3 to move upward, and at the same time start the second cylinder 52 of the downward pulling mechanism to drive the downward pulling block 6 to move downward, straightening and tensioning the annular fabric 13;

[0036] Next, turn on the electric heating block 9 to heat the outside of the annular fabric 13. At the same time, start the third cylinder 10 so that its output shaft pushes the lifting block 11 to move vertically within the limit frame 14, driving the T-shaped friction block 12 to generate friction with one end of the annular fabric 13 close to the lifting block 11, simulating the actual wear condition. By visually observing the wear resistance of the worn part on the annular fabric 13 within a certain period of time, the wear resistance of the annular fabric 13 can be quickly tested, and the wear resistance of the annular fabric 13 at different temperatures can be detected;

[0037] If it is necessary to detect the impact wear resistance of the fabric, the fourth cylinder 16 of the moving mechanism can be started to push the slider 8 on the support block 15 to slide within the vertical frame 2, so that the end of the slider 8 reciprocally impacts the annular fabric 13 in a tightened state. By observing the wear degree of the annular fabric 13 within the set time, including frictional loss and impact damage, the wear resistance of the fabric can be comprehensively evaluated.
