[0002] In the sole quality inspection process, circular or rectangular sample materials must be cut from specific parts of the sole in advance. Since the sole itself has three-dimensional curved surface features such as the arch curvature and forefoot warping, the cut sample still retains the original curvature shape. Direct inspection will lead to uneven force on the contact surface and data distortion. Usually, such samples are polished into a regular 1cm test block with uniform thickness to eliminate surface interference and meet the flatness requirements of the testing instrument for the sample.

[0019] The cover plate of the present invention is provided with a circular opening in the middle part, and four strip-shaped grooves forming a rectangular structure are provided on the outside of the circular opening. The circular opening corresponds to the rectangular space position formed by the four toothed edge clamping blocks, so that the shoe material to be tested can pass through the inside for clamping and positioning. The four rectangular blocks of the four toothed edge clamping blocks are respectively slidably connected to the inside of the four strip-shaped grooves to ensure the stability of the position movement of the four toothed edge clamping blocks. When the inner gear ring rotates, the four toothed edge clamping blocks are driven to slide in position through cooperation with the four gear plates.

When the front of the correction roller is lifted up, the sanding belt is driven to slide and adjust its position to the rear side. When the front of the correction roller moves downward, the sanding belt is driven to slide and adjust its position to the front side, thereby correcting the deviation of the sanding belt, preventing the sanding belt from deviating and falling off, and greatly reducing abnormal loss of the sanding belt.

[0021] The upper and lower bin covers of the present invention are both provided with translucent rectangular windows to facilitate monitoring and observation of the internal polishing process.

When the upper and lower bin covers are closed at the front side of the bin cover, dust overflow is reduced to avoid pollution to the environment. BRIEF DESCRIPTION OF THE DRAWINGS

A limiting post 611 is provided on the front upper portion of the right side wall for limiting the opening and closing handle 62. When the opening and closing handle 62 contacts the limiting post 611, the pulley 66 of the lower compartment cover 65 is located in the upper half of the guide slot 67. At this time, the upper compartment cover 64 and the lower compartment cover 65 are folded and opened to the front of the compartment cover 61, so that the sole material can be disassembled, assembled, and polished. When the upper compartment cover 64 and the lower compartment cover 65 are closed in front of the compartment cover 61, dust leakage is reduced, thereby avoiding environmental pollution.

[0042] The working principle of the polishing device for sole test piece testing of the present invention is as follows:

[0043] First, after sampling the round or rectangular material to be tested from the sole, take the material to be tested to this design and grind it into a uniform material with a thickness of 0.8-1.2cm;

[0044] Second, press the opening and closing handle 62 downward to lift the upper compartment cover 64. The lower compartment cover 65 moves upward along with the upper compartment cover 64, causing the pulley 66 to slide in the guide groove 67. The lower compartment cover 65 is folded toward the upper compartment cover 64 and close to the top of the front of the compartment cover 61, thus opening the front side of the compartment cover 61.

[0045] Third, place the material to be tested in the circular opening in the middle of the two cover plates 366, then control and start the electric push rod 364, which drives the inner gear ring 365 to rotate inside the open ring block 362. As the inner gear ring 365 rotates, it cooperates with the four gear plates 367 to drive the four toothed edge clamping blocks 368 to slide, thereby changing the size of the internal rectangular space and clamping the material to be tested inside the four toothed edge clamping blocks 368.

[0046] Fourth, turn the opening and closing handle 62 to close the upper bin cover 64 and the lower bin cover 65 at the front of the bin cover 61, and then synchronously control and start the first motor 52 in the left sanding belt grinding mechanism 4 and the right sanding belt grinding mechanism 5. The first motor 52 drives the sanding belt 54 to rotate at high speed on the driving roller 53, the first guide roller 56, the second guide roller 57 and the correcting roller 589, and then the linear module in the forward and reverse moving slide 2 drives the left sanding belt grinding mechanism 4 and the right sanding belt grinding mechanism 5 to approach each other so as to contact the two sides of the material to be tested, and perform two-way synchronous grinding on the material to be tested. During the grinding process, the two air nozzles of the air blowing head 7 blow out air at the grinding points on both sides of the material to be tested to reduce the grinding temperature, and the material powder generated by grinding is sucked into the external dust suction device through the dust suction port 8. At the same time, the air flow sucked in during dust suction and the air flow blown out by the air nozzle of the air blowing head 7 work together to accelerate the air flow rate, further cool the sole material, and reduce the impact of dust on the surrounding environment;

[0047] Fifth, when grinding the material to be tested, due to the large friction between the abrasive belt 54 and the material to be tested, the abrasive belt 54 is likely to deviate from the surface of the driving roller 53, the first guide roller 56, the second guide roller 57 and the correction roller 589. When the CCD visual inspection head 510 detects that the abrasive belt 54 has deviated, the second motor 5862 is started. The second motor 5862 acts as a power source to drive the worm 5863 to rotate. Through the cooperation between the worm 5863 and the worm wheel 5865, the toothed disc 5866 drives the toothed column 5867. And the connecting rod 5868 is shifted so that the support block 587 can be rotated and changed in position inside the positioning block 588. When the connecting rod 5868 pushes the bottom of the support block 587 forward, the front of the correction roller 589 is driven to lift upward, so that the sanding belt 54 slides and adjusts its position to the rear side. When the connecting rod 5868 pulls the bottom of the support block 587 backward, the front of the correction roller 589 is driven to move downward, and the sanding belt 54 is driven to slide and adjust its position to the front side, thereby changing the front and rear positions of the sanding belt 54, thereby ensuring the sanding effect of the sanding belt 54 on the sole material.

[0048] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments or to substitute equivalents for some of the technical features. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
