DETAILED DESCRIPTION
[0018] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.
[0019] like Figure 1As shown, a workbench for auxiliary disassembly, separation and transmission of waste household appliances recycling includes a roller conveyor 1, two symmetrically distributed refrigerator door opening structures 5 are fixed on the upper surface of the roller conveyor 1, and two symmetrically distributed fixing frames 2 are fixed on the front and rear sides of the roller conveyor 1. The upper surface of the fixing frame 2 has a plurality of vertical support rods distributed at equal intervals, and a load-bearing plate 3 is fixed on the top of the vertical support rod. The load-bearing plate 3 has a U-shaped structure, and a positioning electric telescopic rod 4 is fixedly installed on the inner side of the load-bearing plate 3. The output shaft end of the positioning electric telescopic rod 4 is bonded with a buffer pad, which includes an outer skin and an inner lining. The inner lining is a sponge material and the outer skin is a rubber material. The waste refrigerator transported on the roller conveyor 1 is positioned by the positioning electric telescopic rod 4 and the buffer pad, thereby ensuring that the edge of the refrigerator door is aligned with the refrigerator door clamping block 507.
[0020] like Figure 2 、 Figure 3 、 Figure 4 and Figure 6 As shown, the refrigerator door opening structure 5 includes a support frame 501, both ends of the support frame 501 are fixed to the roller conveyor 1, a rotating rod 509 is inserted through the top of the support frame 501, one end of the rotating rod 509 is fixed to a rotating sleeve 502, an adjustable electric telescopic rod 505 is fixed on the inner side of the rotating sleeve 502, a lifting block 506 is fixed to the movable end of the adjustable electric telescopic rod 505, a refrigerator door clamping block 507 is fixed to one side of the lifting block 506, a rotating gear 510 is fixed to the outside of the other end of the rotating rod 509, and an output gear 5 is meshed and installed on one side of the rotating gear 510. 11. A rotating motor 504 is fixed to the axis of the output gear 511. A motor fixing plate 503 is provided below the rotating motor 504. One end of the motor fixing plate 503 is fixedly connected to the support frame 501. The lifting and lowering of the refrigerator door clamping block 507 is controlled by adjusting the electric telescopic rod 505, and the edge of the refrigerator door is clamped by the refrigerator door clamping block 507. Then, the rotating motor 504, the output gear 511, the rotating gear 510 and the rotating rod 509 are used to drive the rotating sleeve 502, the adjusting electric telescopic rod 505 and the refrigerator door clamping block 507 to rotate, thereby realizing automatic opening of the refrigerator door.
[0021] A positioning hole 508 is provided on the top of the support frame 501, and the rotating rod 509 is rotated and inserted into the inner side of the positioning hole 508. The end of the rotating rod 509 connected to the rotating sleeve 502 is flush with the side of the support frame 501, and a limited plug-in slot 513 is provided inside the rotating rod 509. The minimum distance between the limited plug-in slot 513 and the rotating sleeve 502 is the same as the thickness of the support frame 501. An anti-deflection plug-in block 512 is detachably installed on the inner side of the limited plug-in slot 513. The anti-deflection plug-in block 512 is an elastic element. The position of the rotating rod 509 is limited by the anti-deflection plug-in block 512 inserted into the inner side of the limited plug-in slot 513 to ensure that the rotating rod 509 does not move along the axial direction during rotation, thereby ensuring that the rotating rod 509 and the support frame 501 will not separate.
[0022] like Figure 5 As shown, the refrigerator door clamping block 507 includes a fixed skin 5071, which is in direct contact and fixed to the lifting block 506. Both ends of the fixed skin 5071 are fixed with curved elastic expansion pieces 5072, and the other end of the curved elastic expansion piece 5072 is fixed with a friction extrusion piece 5073. The existence of the curved elastic expansion piece 5072 allows the distance between the two friction extrusion pieces 5073 to be adjusted to adapt to different refrigerator door thicknesses and clamp the refrigerator door. The bottom end of the friction extrusion piece 5073 is fixed with a guide piece 5074, and the bottom of the guide piece 5074 is inclined at a thirty-degree angle toward the outside. After the guide piece 5074 with the inclined bottom contacts the refrigerator door, the guide piece 5074 can slide along the outside of the refrigerator door, thereby changing the distance between the two friction extrusion pieces 5073.
[0023] like Figure 7 As shown, the anti-deflection plug-in block 512 includes an intermediate connecting piece 5121, and both ends of the intermediate connecting piece 5121 are fixedly installed with a curved elastic connecting piece 5122, the other end of the curved elastic connecting piece 5122 is fixed with a docking connecting piece 5123, and the other end of the docking connecting piece 5123 is fixed with a limiting overlap piece 5124, the limiting overlap piece 5124 is U-shaped, and twice the maximum distance between the two ends of the limiting overlap piece 5124 is less than the width of the two docking connecting piece 5123 brackets, and the maximum distance between the two curved elastic connecting pieces 5122 is greater than the height dimension of the limiting plug-in slot 513, and the limiting overlap piece 5124 with a U-shaped bend at the end of the docking connecting piece 5123 is in contact with the outer surface of the rotating rod 509 to ensure that the anti-deflection plug-in block 512 will not fall after installation.
[0024] Working Principle: First, turn on the power of the device. After the power is turned on, the staff will place the waste refrigerator to be recycled on the surface of the roller conveyor 1 for transportation. When the waste refrigerator moves between the two support frames 501, the roller conveyor 1 stops moving, and the four positioning electric telescopic rods 4 are powered and started at the same time. The positioning electric telescopic rods 4 drive the buffer pads to approach the waste refrigerator. After the buffer pads make contact with the waste refrigerator, they push the waste refrigerator to slide on the roller conveyor 1 until all four buffer pads make contact with the waste refrigerator. At this time, the electric telescopic rod 505 is energized and drives the lifting block 506 and the refrigerator door clamping block 507 to move downward. During this process, the positioning electric telescopic rod 4 is energized and reset. When the refrigerator door clamping block 507 is close to the refrigerator door of the old refrigerator, the bottom end of the guide piece 5074 first contacts the refrigerator door. Since the bottom end of the guide piece 5074 is tilted 30 degrees outward, when the guide piece 5074 moves downward, the guide piece 5074 slides along the outside of the refrigerator door and causes the distance between the two friction and extrusion pieces 5073 to change, until the distance between the two friction and extrusion pieces 5073 is the same as the thickness of the refrigerator door, and the friction and extrusion pieces 5073 clamp the refrigerator door. At this time, the electric telescopic rod 505 is adjusted to drive the lifting block 506 and the refrigerator door clamping block 507 to continue to slide along the refrigerator door. At the same time, the rotating motor 504 is powered on and started to drive the output gear 511 and the rotating gear 510 to rotate. The rotating gear 510 drives the electric telescopic rod 505 to rotate through the rotating rod 509. At this time, the electric telescopic rod 505 is adjusted to drive the rotating motor 504, the lifting block 506 and the refrigerator door clamping block 507 to rotate upward. The refrigerator door clamping block 507, which slides along the outer side of the refrigerator door while rotating upward, drives the refrigerator door to rotate upward and open. The staff only needs to remove the sealing strip on the inside of the refrigerator door after the refrigerator door is opened. After the sealing strip is removed, the rotating motor 504 is reversed and drives the refrigerator door clamping block 507 and the refrigerator door to reset. At the same time, the electric telescopic rod 505 is adjusted to drive the lifting block 506 and the refrigerator door clamping block 507 to reset, so that the refrigerator door is automatically opened without manual operation of the refrigerator door, reducing the workload of the staff and improving the processing efficiency of waste refrigerators when recycling.
