An inclined strip-shaped control hole 414a is provided in the middle of the swing arm 414, and a hook claw 414b is provided at the lower end of the swing arm 414.

[0051] The fourth guide rail slider group 413 is arranged near the swing arm 414, the swing arm push block 415 is installed on the slider of the fourth guide rail slider group 413, a control rod 416 that can slide in the strip control hole 414a is fixed on the swing arm push block 415, and the linear drive assembly 412 is installed on the connecting plate frame 410 to push the swing arm push block 415 to slide left and right along the fourth guide rail slider group 413;

After the plasma is sealed in the bag and loaded on the plate, the pallet loaded with plasma enters along the roller on one side of the quick-freezing machine feeding equipment. The lateral limit mechanism controls the frequency of the pallet entering and exiting. When a pallet enters the middle position of the lateral feeding mechanism, the lateral limit mechanisms on both sides rise to prevent the pallet from moving left and right. At the same time, the longitudinal clamping device on the longitudinal feeding mechanism moves forward until the hook claw is aligned with the strip docking hole on the pallet. The connection with the strip docking hole is achieved by controlling the swing arm to swing, so that the longitudinal clamping device is connected to the pallet. Then, the longitudinal feeding mechanism is used to push the pallet into the plasma quick-freezing machine from the rear side. At this time, the edge of the pallet where the strip docking hole is located is still retained outside the quick-freezing machine, or the pallet can be pushed out of the quick-freezing machine through an active pushing device. After the quick freezing is completed, the pallet is grabbed by the hook claw and transferred forward to the lateral feeding mechanism and pushed out from the other side.

Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the present invention.
