[0023] Embodiment

[0024] Such as Figure 1 、 Figure 2 And Figure 3As shown in the figure, a leather abrasion test machine has a structure including a frame 1 and an abrasion test device disposed on the frame 1 for performing abrasion tests on the test leather 3. The abrasion test device includes a steering wheel seat 2 fixedly connected to the frame 1. The test leather 3 is sleeved on the outer side of the steering wheel seat 2. A polishing cloth strip 4 is provided on the test leather 3. One end of the polishing cloth strip 4 is connected to a weight 5, and the other end of the polishing cloth strip 4 is wound around the test leather 3 on the steering wheel seat 2 and then connected to a conveyor belt 6. A driving transmission device is provided on the side of the conveyor belt 6 away from the polishing cloth strip 4. The conveyor belt 6 is a PP woven belt. The driving transmission device operates to drive the conveyor belt 6 to move back and forth, thereby driving the polishing cloth strip 4 to polish the test leather 3 placed on the steering wheel seat 2 back and forth. With this structure, by adopting an abrasion test device composed of a combination of the steering wheel seat 2, the polishing cloth strip 4, and the weight 5, that is, under the action of the forward and reverse rotation of the driving motor 71, the polishing cloth strip 4 can polish the surface of the test leather 3 placed on the steering wheel seat 2 up and down. By observing the wear degree of the leather surface, its abrasion resistance life is tested. While the structure is simple, the polishing force of the leather can also be adjusted by replacing weights 5 of different weights, improving the test effect.

[0025] As Figure 3 shown, the number of abrasion test devices is 2, and the 2 abrasion test devices are symmetrically arranged left and right. With this structure, the abrasion resistance of two test leathers 3 can be tested on the same device, improving work efficiency.

[0026] As Figure 1 、 Figure 3 shown, the driving transmission device includes a driving motor 71 and a driving wheel 73 tightly connected to the output shaft 72 of the driving motor 71. The number of driving wheels 73 is 2, and the 2 driving wheels 73 are respectively fixedly connected to both sides of the output shaft 72 of the driving motor 71. The fixed end of the conveyor belt 6 is connected to the driving wheel 73. With this structure, that is, when the driving motor 71 rotates forward and backward, the rotation of the output shaft 72 of the driving motor 71 drives the rotation of the driving wheel 73, and then drives the forward and backward movement of the conveyor belt 6 connected thereto, so that the polishing cloth strip 4 can polish the surface of the test leather 3 placed on the steering wheel seat 2 up and down.

[0027] As Figure 3 shown, an auxiliary wheel 74 is rotatably connected to the frame 1. A limiting ring 741 is provided between the two side walls of the wheel groove of the auxiliary wheel 74. A guiding groove for the auxiliary wheel 74 to pass through is formed between the limiting ring 741 and the wheel groove of the auxiliary wheel 74. With this structure, that is, the setting of the limiting ring 741 can prevent the conveyor belt 6 from disengaging from the auxiliary wheel 74 to ensure the stability of the transmission.

[0028] As Figure 1As shown in the figure, a fixed threaded column 11 is fixedly connected to the top of the frame 1, and the middle part of the steering wheel seat 2 and the fixed threaded column 11 are tightly connected by a locking nut. With this structure, that is, a detachable connection method formed by the cooperation of the fixed threaded column 11 and the locking nut is adopted between the steering wheel seat 2 and the frame 1, which can facilitate the quick and efficient replacement and installation when the steering wheel seat 2 is damaged.

[0029] As Figure 2 shown in the figure, the test leather 3 wraps the steering wheel of the steering wheel seat 2 from front to back. Through holes are opened at corresponding positions on both edges of the test leather 3 located at the rear side of the steering wheel, and the upper and lower through holes are locked by fastening bolts 8. With this structure, it is convenient to fix the test leather 3.

[0030] Both ends of the polishing cloth strip 4 are detachably connected to the weight 5 and the conveyor belt 6 respectively. With this structure, for example, detachable structures such as clips, straps and buckles can be used for detachable connection, which is convenient for replacing the conveyor belt 6 and the polishing cloth strip 4 when they are damaged, and is also convenient for replacing weights 5 of different weights.

[0031] During specific use, the test leather 3 wraps the steering wheel of the steering wheel seat 2 from front to back, and the two edges of the test leather 3 located at the rear side of the steering wheel are locked by fastening bolts. Then, the driving motor 71 is started, and the driving motor 71 rotates forward and backward. The rotation of the output shaft 72 of the driving motor 71 drives the rotation of the driving wheel 73, and then drives the back-and-forth movement of the conveyor belt 6 connected thereto, so that the polishing cloth strip 4 can polish the surface of the test leather 3 placed on the steering wheel seat 2 back and forth. The wear resistance life of the leather is tested by observing the wear degree of the leather surface. The structure is simple, and at the same time, by replacing weights 5 of different weights, the polishing force of the leather can also be adjusted to improve the test effect.

[0032] It should be noted that all the electrical components in this application are connected to an external power supply and control system. The control system adopts the structure in the prior art and can be equipped with a switch button, etc. This control system is used to control the operation of the driving motor 71.

[0033] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
