[0042] A second movable groove is arranged at the bottom of the activity cavity. A limiting block 124 is arranged in the second movable groove. A first connecting spring 125 is arranged at the bottom of the limiting block 124. One end of the first connecting spring 125 is fixedly connected to the bottom of the second movable groove. A first inclined surface is arranged on the limiting block 124. A third electromagnet 126 is arranged at the bottom of the second movable groove. The limiting block 124 is made of ferromagnetic metal.

[0043] The feeding rod 104 is provided with a third movable groove. The first movable block 120 is located in the third movable groove. The first movable block 120 is provided with a fourth movable groove. A second push block 127 is arranged in the fourth movable groove. A second connecting spring 128 is arranged on the second push block 127. One end of the second connecting spring 128 is fixedly connected to the inner wall of the fourth movable groove. The second push block 127 is provided with a second inclined surface. A fourth electromagnet 129 is arranged on the first movable block 120, and a third magnetic block is arranged on the second push block 127.

[0044] The feeding rod 104 is provided with a mounting rod 111. The mounting rod 111 is inclined. The mounting rod 111 is provided with a fifth movable groove. A cylinder is arranged in the fifth movable groove. A pushing rod 130 is arranged on the piston rod of the cylinder.

[0045] The pushing rod 130 is provided with a sixth movable groove. A stop block 131 is arranged in the sixth movable groove. A third connecting spring 132 is arranged at the bottom of the stop block 131. The pushing rod 130 is provided with a seventh movable groove. A second movable block 134 is arranged in the seventh movable groove. A return spring 135 is arranged on the second movable block 134. The return spring 135 abuts against the inner wall of the seventh movable groove. The second movable block 134 and the stop block 131 are connected by a connecting rope 133. A convex block 136 is arranged on the inner wall of the fifth movable groove. The convex block 136 penetrates through the seventh movable groove.

[0046] The base 101 is provided with an extension plate 112. The extension plate 112 is provided with a support rod 113. The support rod 113 is provided with a guide rod 114 and a collecting rod 115. One end of the guide rod 114 is located on one side of the mounting frame 102.

[0047] The belt 200 to be processed is placed on the feeding rod 104. The first movable block 120 moves to one end of the feeding rod 104 close to the support frame 103. The fourth electromagnet 129 is energized to attract the second push block 127 to move into the fourth movable groove. When the second push block 127 enters the fourth movable groove and the first movable block 120 moves towards the support frame 103, it does not contact the belt 200. After the first movable block 120 moves to one end of the feeding rod 104, the fourth electromagnet 129 is powered off. The second connecting spring 128 pushes the second push block 127 to move out of the fourth movable groove. The second push block 127 extends out of the fourth movable groove. The first movable block 120 moves towards the mounting frame 102. The second push block 127 pushes the belt 200 on the feeding rod 104 to move towards the mounting frame 102. Through the setting of the second inclined surface, the second push block 127 can intercept a part of the belt 200 from between multiple belts 200 and push it, and does not necessarily move to one end of all the belts 200 before pushing the belt 200 to move.

[0048] The second pushing block 127 stops moving after pushing a belt 200 off the feeding rod 104. The dropped belt 200 lands on the pushing rod 130. At this time, the stop block 131 is in the raised state, and the belt 200 is placed on the side wall of the stop block 131. The air cylinder pushes the pushing rod 130 to move towards the mounting frame 102. The pushing rod 130 drives the belt 200 to move towards the roller 106. When the belt 200 moves onto the roller 106, the second movable block 134 moves to one side of the convex block 136. When the pushing rod 130 continues to move, the convex block 136 blocks the movement of the second movable block 134. The pushing rod 130 moves relative to the second movable block 134, and the connecting rope 133 pulls the stop block 131 into the sixth movable groove. The stop block 131 enters the sixth movable groove. Since the pushing rod 130 and the mounting rod 111 are both inclined with respect to the mounting frame 102, the belt 200 on the pushing rod 130 falls from the pushing rod 130 onto the roller 106. At this time, the belt 200 is simultaneously sleeved on the roller 106 and the tensioning roller 119. The air cylinder drives the pushing rod 130 to move back. The first electromagnet 117 is energized to attract the first movable rod 107 to move downward. The tensioning roller 119 and the roller 106 cooperate to tension the belt 200. The movable frame 105 moves upward so that the belt 200 contacts the grinding wheel 116. The roller 106 drives the belt 200 to rotate to wedge the belt 200. After the belt 200 is wedged, the movable frame 105 moves downward. The first electromagnet 117 is de-energized so that the belt 200 is in a relaxed state. The third electromagnet 126 is energized to attract the limit block 124 into the second movable groove. The first pushing block 110 extends from the first movable groove and impacts on the belt 200. The belt 200 falls on the guide rod 114 and moves along the guide rod 114 to the collecting rod 115 to collect the processed belt 200. The second electromagnet 123 is energized to attract the second movable rod 121 to move into the movable cavity, causing the first pushing block 110 to reset.

[0049] The above description is only some preferred embodiments of the present disclosure and an explanation of the applied technical principles. Those skilled in the art should understand that the scope of the utility model involved in the embodiments of the present disclosure is not limited to the technical solutions formed by the specific combination of the above technical features.
