[0041] Specifically, the removed unqualified quick-frozen food products can be transported to the top of the waste collection box 20. After that, the negative pressure adsorption is released, so that the unqualified quick-frozen food products can be stably dropped into the waste collection box 20, thereby realizing the collection of unqualified products.

[0042] In summary, when the overall equipment is in use:

[0043] The packaged quick-frozen food to be tested is placed on the feed end of the conveyor belt 2 and conveyed by the conveyor belt 2.

[0046] During this process, the motor 17 drives the screw rod 16 to rotate. Through the threaded connection relationship between the screw rod 16 and the driving block 8 and the movement limit relationship between the driving block 8 and the limit rod 18, the driving block 8 can be controlled to drive the second electric push rod 9 to move vertically relative to the conveying direction of the conveyor belt 2. When it moves to the unqualified product position, the operation of the motor 17 is stopped.

[0047] Afterwards, the second electric push rod 9 is controlled to drive the vacuum suction cup 10 to descend, thereby vacuum-absorbing the unqualified products. Afterwards, the second electric push rod 9 is controlled to control the vacuum suction cup 10 to move the unqualified products upward.

[0048] Then, the motor 17 is controlled to move so that the vacuum suction cup 10 moves the defective products off the conveyor belt 2 and is positioned above the waste collection box 20. The vacuum suction cup 10 is released from adsorption, so that the defective products can fall into the waste collection box 20 for collection, thereby achieving the removal of the defective products from the conveyor belt 2.
