Description

Technical Field

[0001] The present invention relates to a wear-resistant testing device for popcorn soles, belonging to the field of sole testing devices. Background Art

[0002] In the field of shoe materials, popcorn soles refer to soles processed with expanded thermoplastic particles (currently, most in the industry are expanded thermoplastic polyurethanes, i.e., ETPU, also called expanded TPU or popcorn particles). Popcorn soles have many advantages such as soft texture, good elasticity, excellent buffering performance, low energy consumption under pressure, good durability, and good heat insulation performance. Their surfaces present a granular appearance texture and are favored by many consumers.

[0003] During the use of popcorn soles, when the sides of the soles are scratched, there may be a risk of shedding and breaking of the expanded thermoplastic particles. The existing sole durability testing devices are mainly flexing resistance devices, including normal temperature and low temperature types. Since the principle of flexing resistance testing is to simulate the bending action when a person walks and does not consider the contact and wear between materials, it is impossible to test whether there is a durability risk of popcorn soles shedding particles.

[0004] In view of this, the inventor of this case conducted in-depth research on the above problems, and thus this case was born. Summary of the Invention

[0005] The purpose of the present invention is to provide a wear-resistant testing device for popcorn soles that can detect whether popcorn particles are prone to falling off.

[0006] To achieve the above purpose, the present invention adopts the following technical solution:

[0007] A wear-resistant testing device for popcorn soles, in a space, defines three mutually perpendicular directions as the first direction, the second direction, and the third direction. It includes a frame, a first fixing mechanism for installing one sole, a second fixing mechanism for installing the other sole, a first driving mechanism for driving the first fixing mechanism to move back and forth in the first direction, and a second driving mechanism for driving the second fixing mechanism to move back and forth in the first direction. The first fixing mechanism and the second fixing mechanism are arranged in cooperation.

[0008] As a preferred mode of the present invention, the first direction is the front-back direction, the second direction is the left-right direction, and the third direction is the up-down direction.

[0009] As a preferred mode of the present invention, the first driving mechanism is a screw driving mechanism, a cylinder driving mechanism, an oil cylinder driving mechanism, or an electric push rod, and the second driving mechanism is a screw driving mechanism, a cylinder driving mechanism, an oil cylinder driving mechanism, or an electric push rod.

[0010] As a preferred embodiment of the present invention, the first driving mechanism includes a first motor, a first lead screw, a first lead screw nut, a first sliding seat, and a first slider. The first lead screw nut is disposed on the first lead screw, the first slider is mounted on the first lead screw nut, and the first slider is configured to slide back and forth relative to the first sliding seat. The first fixing mechanism is installed on the first slider.

The second lead screw nut is disposed on the second lead screw, the second slider is mounted on the second lead screw nut, and the second slider is configured to slide back and forth relative to the second sliding seat. The second fixing mechanism is installed on the second slider.

More specifically, it is the friction on the sides of the two soles. Through multiple frictions, it can be observed whether the popcorn particles on the sole fall off. The present invention can set the number of frictions, so as to more objectively judge the anti-abrasion or wear-resistant performance of the popcorn particles on the side of the sole. Preferably, through the settings of the third mechanism, the fourth mechanism, the first swing block, the second swing block, the third swing block and the fourth swing block, the relative position, relative pressure and swing angle of the two soles can be adjusted to more realistically simulate the human walking form, so as to better test the anti-off ability of the popcorn particles on the popcorn sole in the actual use scenario.

[0039] In order to further explain the technical solution of the present invention, the following will be elaborated in detail with reference to embodiments.

[0040] Refer to Figures 1 to 4 , a wear resistance testing device for popcorn soles. In the space, three directions perpendicular to each other in pairs are defined as the first direction, the second direction, and the third direction. In the normal use state of the device, the first direction is the front-back direction, the second direction is the left-right direction, and the third direction is the up-down direction.

[0041] The present invention includes a frame 100, a first fixing mechanism 30 for installing one sole 31, a second fixing mechanism 40 for installing the other sole 31, a first driving mechanism 10 for driving the first fixing mechanism 30 to move back and forth in the first direction, and a second driving mechanism 20 for driving the second fixing mechanism 40 to move back and forth in the first direction.

The first slider 13 is installed on the first lead screw nut, and the first slider can slide back and forth relative to the first sliding seat 18. The first fixing mechanism 30 is installed on the first slider 13. As a preferred embodiment of the present invention, the second driving mechanism 20 includes a second motor 21, a second lead screw 22, a second lead screw nut, a second sliding seat 28, and a second slider 23. The second lead screw 22 is arranged in the front-back direction. The second lead screw nut 29 is arranged on the second lead screw 22. The second slider 23 is installed on the second lead screw nut 29, and the second slider 23 can slide back and forth relative to the second sliding seat 28. The second fixing mechanism 40 is installed on the second slider 23.

[0044] As a preferred embodiment of the present invention, the first fixing mechanism 30 is mounted on the first driving mechanism 10 through a third mechanism capable of adjusting the position of the first fixing mechanism 30 in the left-right direction, and the second fixing mechanism 40 is mounted on the second driving mechanism 20 through a fourth mechanism capable of adjusting the position of the second fixing mechanism 40 in the left-right direction. In an embodiment, both the third mechanism and the fourth mechanism are cylinders, that is, the third mechanism is the first cylinder 14 and the fourth mechanism is the second cylinder 24, and the pressure of the two cylinders is 0.01 - 0.1 MPa, so as to realize the automatic adjustment of the first fixing mechanism 30 and the second fixing mechanism 40. By adjusting the relative positions of the first fixing mechanism 30 and the second fixing mechanism 40, the friction force of the contact surfaces of the two shoe soles 31 can be adjusted, and the contact pressure of the two shoe soles can be adjusted through the first cylinder 14 and the second cylinder 24 to better simulate the actual use scenario of the shoe sole 31. The present invention is not limited to the use of an automatic adjustment mechanism, and a manual adjustment mechanism can also be used to adjust and position the left-right direction positions of the first fixing mechanism 30 and the second fixing mechanism 40.

[0045] As a preferred embodiment of the present invention, a first mounting shaft 15 extending in the left-right direction is provided on the third mechanism, and a first swing block 16 capable of performing yaw adjustment in the vertical plane direction is provided on the first mounting shaft 15. The first swing block 16 is fixed on the first mounting shaft 15 through a first positioning mechanism.

An arc-shaped groove 102 is provided on each swing block, and the screw is inserted into the arc-shaped groove 102. When the swing block swings to a predetermined angle, the screw is locked in the corresponding position to realize the fixation of the swing block. In the present utility model, the first positioning mechanism, the second positioning mechanism, the third positioning mechanism, and the fourth positioning mechanism can also adopt a stepping motor. The motor drives the swing to rotate a certain angle. When using a motor, during the mutual friction process of the two shoe soles 31, the motor can continuously and automatically adjust the position of the swing block, thereby real-time adjusting the angle of the shoe sole 31 to more realistically simulate the state of the shoe sole 31 when walking.

The present invention can design other clamping mechanisms to clamp the upper and lower surfaces of the sole 31 through the clamping mechanisms for friction testing.

[0050] The present invention further provides a tray 101 on the frame 100. The tray 101 can receive the dropped popcorn kernels or can be provided with materials such as sediment, cement, etc. in the tray 101 to simulate a real environment.

[0051] The product form of the present invention is not limited to the embodiments of this case. Any person who makes appropriate changes or modifications with a similar idea shall be regarded as not departing from the patent scope of the present invention.
