The intermittent mechanism stops for a while and moves for a while. When the conveyor belt 5 is conveying, the workpiece can be just sent to the inside of the support frame 4, and then the conveyor belt 5 stops. When the support frame 4 is sent to a high place and then returns to the bottom, the conveyor belt 5 continues to move and sends the next workpiece to the inside of the support frame 4. After the workpiece reaches the inside of the support frame 4, the staff can turn on the second motor 3, so that the lifting mechanism will take the support frame 4 to a high place, and then the staff turns on the first motor 2, and the rotating mechanism rotates with the support seat 25, and the support frame 4 can be rotated to the specified position. The bottom of the support frame 4 can be opened. After opening, the workpiece can be left at a high place, and then reversely rotated back to the original position, and the descending takes the support frame 4 back to the bottom again. By setting the cooperation of the intermittent mechanism and the lifting and rotating mechanism, the staff does not need to manually move the workpiece to the inside of the support frame 4. The device can automatically load and transport, saving manpower and improving work efficiency.

[0020] The rotating mechanism includes a first rotating shaft 21, which is rotatably connected to the output end of the first motor 2, a first gear 22 is fixedly connected to one side of the first rotating shaft 21, a second gear 23 is meshedly connected to one side of the first gear 22, the second gear 23 is fixedly connected to a support seat 25, a round block 24 is fixedly connected to the bottom of the second gear 23, and the round block 24 is rotatably connected to the base 1; when the staff turns on the first motor 2, the first motor 2 is fixedly installed on the inner side of the base 1 through the frame, so that the first rotating shaft 21 will rotate, the first gear 22 fixedly connected to one side rotates, and the second gear 23 meshed with it will rotate, and the second gear 23 and the support seat 25 are fixedly connected, so that the support seat 25 can also rotate, and the second gear 23 is mainly the round block 24 fixedly connected to the bottom, which can rotate inside the base 1, so the second gear 23 rotates normally under meshing. By providing a rotating mechanism, the workpiece can be sent to a designated position at a high place, and the operation is simple.

[0021] The lifting mechanism includes a second rotating shaft 31, which is rotatably connected to the output end of the second motor 3, a half gear 32 is fixedly connected to one side of the second rotating shaft 31, a third gear 33 is meshedly connected to one side of the half gear 32, a round rod 34 is fixedly connected to one side of the third gear 33, a rotating rod 35 is fixedly connected to one side of the round rod 34, a rocker 36 is rotatably connected to one side of the rotating rod 35, a block 37 is rotatably connected to one side of the rocker 36, a groove is provided inside the support seat 25, the block 37 is slidably connected to the groove, the block 37 is fixedly connected to the support frame 4, a support block 26 is fixedly connected to one side of the support seat 25, and the support block 26 is rotatably connected to the round rod 34; when the staff turns on the second electric Machine 3, the second rotating shaft 31 rotates, and the half gear 32 fixedly connected thereto rotates, so that the third gear 33 meshingly connected at the bottom rotates, and the round rod 34 on one side of the third gear 33 rotates inside the support block 26, so that the third gear 33 and the round rod 34 are fixedly connected, and the rotation of the third gear 33 can rotate the round rod 34, so that the rotating rod 35 fixedly connected on the other side of the round rod 34 can also rotate, and it moves with the rocker 36. The rocker 36 and the rotating rod 35 and the block 37 are all rotatably connected, mainly to prevent movement from being restricted, so that the rotating rod 35 can also drive the rocker 36 upward or downward while rotating a large circle, so that the block 37 can move up and down, and the support frame 4 can be raised and lowered. The third gear 33 rotates, and the block 37 moves up and down. This movement is reciprocating, and the half gear 32 has only half of the teeth. This half of the teeth can make the third gear 33 rotate, and the block 37 moves upward. After reaching the top, it stops, and then rotates to the part without teeth of the half gear 32. After waiting for a while, it rotates to the part with teeth, and rotates with the third gear 33, and the block 37 moves downward.

The main reason is that the vertical gear 62 has only half of the teeth, so the part with teeth can rotate with the fourth gear 63, but the part without teeth, the fourth gear 63 does not rotate, and the conveyor belt 5 stops, so that the workpieces can be sent to the inside of the support frame 4 one by one, and the workpieces are also arranged at a certain distance on the top of the conveyor belt 5, so the work is carried out in an orderly manner, and the material is automatically loaded, saving manpower.

[0023] The vertical gear 62 has only half of the teeth; the toothed portion brings the conveyor belt 5 forward, and the toothless portion of the conveyor belt 5 is paused.
