Under the action of the tension spring 19, the clamping block 17 is located at the limit near the center of symmetry. The iron 78 is not energized, and the pressure relief valve 25 is closed.

[0036] During operation, the waste compressor is placed on the conveyor belt 13 and the conveyor motor 16 is started. The conveyor motor 16 drives the conveyor belt 13 to move backward through the conveyor shaft 15 on the front side and the conveyor wheel 14 on the front side, while holding the block 17 Under the guidance limit, the compressor moves to the lower side of the sliding table 68, and then the conveying motor 16 stops and starts the auxiliary motor 48.

The rotating shaft 61 drives the piston cylinder 39 to rotate. The piston cylinder 39 drives the motor slide 36 through the piston 43 and the piston rod 42. At the same time, the linear motor 34 starts to move closer to the center of symmetry. When one side moves and feeds, the motor 31 starts to drive the motor shaft 24 and the cutting wheel 22 to rotate to realize the cutting of the compressor casing. After the cutting is completed, the clamping block 70 clamps the upper cover of the compressor that has been cut to release the pressure. The valve 56 is closed, the motor 31 stops, the linear motor 34 moves to the side away from the center of symmetry and resets, the auxiliary motor 48 reverses, the electromagnet 78 loses power, and the auxiliary tension spring 73 resets the spline cylinder 74 to move upward, and the air pump 51 generates a negative Press to reset the piston 43 to move up, while the piston 43 moves up The generated negative pressure drives the slider 44 forward through the auxiliary air pipe 53. When the trapezoidal block 66 abuts the wedge block 65, the trapezoidal block 66 pushes the wedge block 65 to move to both sides to reset, so that the clamping block 70 and the upper cover plate When disengaged, the upper cover plate falls into the recovery chamber 84, and at the same time, the spring 81 causes the lifting block 80 to move downward and reset, the cone block 64 and the wedge block 65 abut again, and then the pressure relief valve 56 opens, and the return spring 58 causes the slide plug 44 moves backward to reset, after the motor slide rail 36 rotates to two photoelectric switches 33 corresponding again, the auxiliary motor 48 stops to complete the reset of the entire device.

[0037] The beneficial effect of the present invention is that the conveying mechanism of the present invention is provided with a guide mechanism. After the operator places the compressor on the conveyor belt, under the action of the guide mechanism, the conveying mechanism can accurately convey the compressor to the clamping mechanism. Side, after that, the lifting mechanism drives the clamping mechanism and cutting mechanism to move down. After the clamping mechanism contacts the compressor, it automatically clamps and fixes the compressor. After that, the cutting mechanism cuts the compressor casing. After the cutting is completed, the clamping mechanism clamps the After the upper cover plate is cut, the lifting mechanism drives the clamping mechanism and the cutting mechanism to move upward and reset. During the upward movement, the clamping mechanism can move forward to convey the upper cover plate into the recycling box, and release the upper cover plate to realize automatic The upper cover is recovered and stored. Therefore, the present invention can automatically clamp and fix the compressor, and the installation and fixing process is simple, so that the overall processing efficiency is improved.
