The clamping piece 322 is provided with a groove structure, the groove structure arranged on the clamping piece 322 is clamped with a lug structure arranged on the pressing block 317, and the pressing block 317 is fixed on the inner wall of the bottom of the bearing outer frame 311 through a spring.

The working principle is as follows: the lifting height of the first electric telescopic rod 23 is controlled through the control box 12, the height adaptation of the composite wood-plastic material receiving component 3 and the feeding platform is realized, the first electric telescopic rod 23 stretches and retracts to drive the end plate 24 to lift, so that the lifting effect of the composite wood-plastic material receiving component 3 is achieved, the end plate 24 is set to be a Y-shaped plate body component, the bearing area is increased, the bearing capacity of the end plate 24 is improved, the sliding block 313 slides in the second sliding groove 15 in the lifting process of the receiving outer frame 311, the position stability of the receiving outer frame 311 in the lifting process is ensured, the receiving outer frame 311 in the initial state is positioned at the top of the machine box body 13, when the receiving outer frame 311 moves from top to bottom, the gear 315 is in contact with the inner wall of the smooth machine box body 13, the gear 315 does not rotate until the gear 315 is in contact with the rack 17 arranged on the inner wall of, the link rod 316 is caused to rotate downwards and press the pressing block 317, the pressing block 317 moves downwards to release the engagement between the bump structure on the pressing block 317 and the engagement piece 322, the feeding outer frame 321 rotates outwards around the rotating shaft 323 under the action of the main limiting spring 327, the rotating shaft 323 is located at the front side of the third sliding chute 314, the sleeved portion of the feeding outer frame 321 and the rotating shaft 323 is not on the central axis of the feeding outer frame 321, so that the feeding outer frame 321 will fall downwards under the action of gravity until the bottom of the feeding outer frame 321 contacts with the ground after rotating out, at this time, the feeding outer frame 321 is pushed inwards by manpower to move the rotating shaft 323 from the front side of the third sliding chute 314 to the rear side of the third sliding chute 314, the distance between the feeding outer frame 321 and the machine case 13 is reduced, under the blocking action of the machine case 13, the main limiting spring 327 maintains the stretched state, and the position of the feeding outer frame 321 is limited, meanwhile, the wedge block 329 loses the limitation of the position of the groove top surface of the mounting groove 3110 to the wedge block, the wedge block upwards pops under the restoring force action of the secondary limiting spring 3210 to play a role of a bridge connecting the material conveying outer frame 321 with the receiving outer frame 311, a worker can convey the wood-plastic board by using the conveyor belt structure 326 to enable the wood-plastic board to be upwards conveyed into the receiving groove 312, and the feeding process of the wood-plastic board is realized.

In conclusion, according to the lifting mechanism for stacking and feeding in wood plastic processing, the rotary material conveying structure 32 is arranged inside the wood plastic material receiving outer frame structure 31, so that each device has the material conveying structure of the device, the rotary material conveying structure 32 is accommodated inside the wood plastic material receiving outer frame structure 31 in an unused state, the occupied area is small, the device can be automatically popped out during use, the feeding process of workers is more convenient, the rotary material conveying structure 32 is matched with the wood plastic material receiving outer frame structure 31, the problem of height non-adaption caused by an external material conveying structure is avoided, the position of the material conveying structure does not need to be manually debugged during use, and the feeding efficiency of wood plastic plates is effectively improved; second electric telescopic handle 319 is in the shrink state during wood-plastic board material loading, and after lifting unit 2 began to start, second electric telescopic handle 319 outwards stretched out, carried on spacingly to the inside wood-plastic board of accepting groove 312, and simple structure need not manual operation and can realize that wood-plastic board's automation is spacing, and labour saving and time saving effectively guarantees the position stability of wood-plastic board in the transportation.

The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be able to cover the technical solutions and the inventive concepts of the present invention within the technical scope of the present invention.
