V-shaped guide mechanism 4 is arranged between floating horizontal moving part 1 and fixed longitudinal moving part 2, and the V-shaped guide mechanism 4 is used to realize the sliding guide in the lifting of floating horizontal moving part.

[0019] As shown in the accompanying Figure 2 , the fixed longitudinal moving part 2 of the embodiment includes fixed base 21, four groups of front and back drive drums 23 are arranged on the fixed base 21 through bearing seat 22, one side of the front and back drive drums 23 is connected with front and back drive speed reducer 26 of front and back drive motor 25 through chain transmission mechanism 24, distance measuring sensor 27 and proximity switch 28 are further arranged on the fixed base 21, and the distance measuring sensor 27, the proximity switch 28 and the front and back drive motor 25 are electrically connected with the PLC electric control system respectively.

[0020] As shown in the accompanying Figure 2 , 3 , the floating horizontal moving part 1 of the embodiment includes lifting floating rack 11, the lifting floating rack 11 is connected with the hydraulic lifting system 3 below, left and right drive shaft 14 driven by speed reducer 13 of left and right drive motor 12 is arranged on one side of the lifting floating rack 11 above, and left and right driven sprocket 15 is arranged on the other side, left and right drive sprocket 16 is arranged on the left and right drive shaft 14, U-shaped cover plate chain 17 and ordinary chain 18 are arranged between the left and right drive sprocket 16 and the left and right driven sprocket 15, and the left and right drive motor 12 is electrically connected with the PLC electric control system. U-shaped cover plate chain 17 and ordinary chain 18 are three groups, and each group of U-shaped cover plate chain and ordinary chain is located between two groups of front and back drive drums 23 of the fixed longitudinal moving part.

[0021] The hydraulic lifting system of this embodiment includes an electric hydraulic pump station, which is connected to a jack located below the floating horizontal movement component via a high-pressure oil pipe and an oil pipe interface. A synchronous flow divider valve is installed on the high-pressure oil pipe, and the electric hydraulic pump station and the synchronous flow divider valve are electrically connected to the PLC control system.

[0022] This embodiment of a hydraulic lifting and vertical reversing mechanism for artificial plywood comprises a floating lateral movement component, a fixed longitudinal movement component, a hydraulic lifting system, and a PLC electrical control system. The fixed longitudinal movement component is installed at a designated working position via expansion bolts. A V-shaped guide mechanism is provided between the floating lateral movement component and the fixed longitudinal movement component. The V-shaped guide mechanism is used to achieve sliding guidance during the lifting and lowering of the floating lateral movement component.

[0023] like Figure 1 As shown, a pile of plywood moves forward from the fixed longitudinal moving component 2 and enters the mechanism via the front and rear drive rollers 23. When the front end of the template blocks the proximity switch 28, the signal is fed back to the PLC control system. The PLC control system controls the front and rear drive motors 25 to stop. Then, the PLC control system controls the hydraulic lifting system to lift the floating transverse moving component 1. Then, the left and right drive motors 12 are started. The left and right drive motors 12 drive the U-shaped cover chain 17 and the ordinary chain 18 through the left and right drive shafts and left and right drive sprockets, sending the pile of plywood to be packed into the packing mechanism. After packing, the plywood returns to the front and rear drive rollers 23 of the fixed longitudinal moving component 2 via the floating transverse moving component 1. During this process, whether it is forward rotation to be sent into the packing mechanism or reverse rotation to return to the front and rear drive rollers, the U-shaped cover chain and the ordinary chain are in a taut state, ensuring that the load can be transmitted on the taut U-shaped cover chain in both forward and reverse rotation.

[0024] When the ranging sensor 27 detects that the plywood has returned to the specified distance, it sends a signal to the PLC control system. The PLC control system then stops the left and right drive motors 12. Next, the PLC control system controls the hydraulic lifting system to lower the floating transverse component 1. Then, the plywood enters the next process from the front of the fixed longitudinal component 2.
