[0010] The beneficial effects of the utility model are:

[0011] The heavy-duty automatic destacking machine provided by the utility model blocks the frame in the stacking state in the forward state by a blocking device and stops it at a set position. The lifting plate on the lifting platform is positioned between two frames in the stacking state by controlling the lifting platform. The lifting plate is extended to lift the lifting platform, and the frame at the bottom is left on the chain conveyor and transported to the next place, thereby realizing automatic destacking and improving destacking efficiency.

[0015] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0016] like Figure 1 As shown, the fixing frame 4 is a steel frame fixed to the ground, mainly used for assembling the lifting platform 2.

[0017] A heavy-duty automatic destacker, a chain conveyor 1, is used to transport the frames 6 in a stacked state;

[0018] The blocking device 5 is arranged at the front end of the chain conveyor 1. The blocking device 5 extends the blocking part by extending the cylinder. The blocking part is provided with a detection switch. The detection switch is used to detect whether the frame in the stacking state on the chain conveyor 1 is in the set position; when the blocking device 5 is extended, it can block the frame 6 in the stacking state that is in the moving state, and position the frame 6 in the stacking state under the lifting platform 2.

[0019] A lifting platform 2 is mounted on the fixed frame 1. The lifting platform 2 is shaped like a hollow square, with the center portion being used to access the stacking frames 6. The lifting platform 2 can be lowered from the top of the stacking frames 6 to the bottom of the stacking frames 6. A telescopic cylinder 3 is mounted on the lifting platform 2, which is equipped with a lifting plate 8 for insertion between two stacking frames 6.

[0020] The lifting platform 2 is provided with a lifting motor 9, which is arranged on the top of the fixing frame 4. The lifting motor 9 lifts the lifting platform body up and down in the vertical direction through a transmission rod and a chain or a guide rail.

[0021] During operation, the chain conveyor 1 transports stacked frames, each stack containing eight frames. A forklift loads the stacked frames onto the chain conveyor 1, which uses a flat chain as its conveyor chain. The finished frame stack 6 is transported by the chain conveyor 1 to the blocking device 5. At this point, the cylinder of the blocking device 5 is extended. Simultaneously, a detection switch detects the arrival of the finished stack, halting the chain conveyor 1 and retracting the blocking device 5. The blocking device 5 consists of two cylinders with guide rods, controlled by a solenoid valve. The two cylinders must rise or fall simultaneously.

[0022] The fixed frame 4 is composed of two small frames with four columns on each side, which are connected and assembled through an intermediate horizontal brace. The sides of the two small frames on the left and right are respectively provided with two linear guide rails in the vertical direction. The lifting platform 2 is installed on the vertical linear guide rails on the left and right sides. The lifting platforms 2 on the left and right sides are driven by a lifting motor 9 on the upper part. The lifting motor 9 can be equipped with a rotary encoder, and the rotary encoder controls the lifting height of the lifting platform 2 each time. Two telescopic cylinders 3 are installed on each lifting platform 2. Two horizontal linear guide rails 7 are installed on the telescopic cylinder 3, and lifting plates 8 are installed on the two horizontal linear guide rails 7. The two groups of telescopic cylinders 3 on the left and right are extended at the same time and inserted between the bottom frame and the seven frame rails above. The lifting plates 8 lift the remaining seven stacked frames, and the chain conveyor 1 runs to transport the frames on it to the next position. The lifting plate on telescopic cylinder 3 lifts all seven frames above the second frame. After lifting platform 2 rises 80mm, completely disengaging the first and second frames, lifting platform 2 stops rising. The rising height is calculated and controlled by an encoder. Chain conveyor 1 starts, driving the frames on it forward until the detection switch at the front detects that the forward frame is in place. Chain conveyor 1 stops, completing the unstacking and conveying of the first frame. Lifting platform 2 then places the already lifted, stacked frame 6 onto chain conveyor 1, and the above steps are repeated until all eight frames are unstacking.
