[0028] The present utility model provides a folding tray machine adapted to multiple trays as shown in Figures 1-5 which includes:

[0029] A frame body 100;

[0030] A conveying device 200, one end of the conveying device 200 extends to the inner bottom of the frame body 100;

[0031] A guiding device 300, the guiding device 300 includes a guiding edge 301 arranged inside the frame body 100, a positioning block 302 arranged on the frame body 100, and a connecting rod 303 arranged outside the frame body 100. One end of the connecting rod 303 is fixedly connected to the guiding edge 301, and the connecting rod 303 is fixedly connected to the positioning block 302 through a pin 304;

[0032] A fork extending device 400, the fork extending device 400 includes an installation box 401 fixed at the bottom of the connecting rod 303. One side of the installation box 401 is provided with an opening. A rotating cylinder 402 and a connecting block 403 are fixed on the inner top surface of the installation box 401. A regulating block 404 is fixed on the bottom workbench of the rotating cylinder 402. Both ends of the regulating block 404 are movably connected with a connecting rod 405. The bottom end of the connecting block 403 is movably connected with a blocking member 406, and one end of the blocking member 406 is movably connected with the other end of the connecting rod 405;

[0033] A jacking device 500, the jacking device 500 is arranged at the inner bottom of the frame body 100.

[0034] In addition, the frame body 100 is made of several square tubes welded together. The frame body 100 is a rectangular structure without a top cover and with an opening on one side, which is convenient for a forklift to take out or put in the stacked pallets through the opening. A lifting ring 101 is fixed to the top of the frame body 100 for easy movement. A baffle 102 and a blocking net 103 are fixed to the side surface of the frame body 100, which can play a protective role and prevent the structure inside the frame body 100 from being collided, and also prevent debris from falling into the frame body 100. Among them, the baffle 102 is arranged at the bottom of two adjacent side surfaces of the frame body 100, and the blocking net 103 is arranged in the middle and top of three adjacent side surfaces of the frame body 100. The blocking net 103 is also provided with a strip opening for the connection rod 303 and the latch 304 to pass through.

[0035] Specifically, the conveying device 200 uses a chain conveyor 201. There are two chain conveyors 201 in total. The two chain conveyors 201 are respectively arranged on both sides of the lifting device 500, so as to convey the pallet more stably.

[0036] It is worth mentioning that the chain conveyor 201 includes a fuselage 2011 and a power box 2012 arranged at the bottom of the fuselage 2011, a chain 2013 is arranged around the fuselage 2011, and a driving motor 2014 is arranged in the power box 2012. The driving motor 2014 is connected to the chain 2013 through a sprocket, and can transmit the power of the driving motor 2014 to the chain 2013, and then drive the pallet to the designated position through the chain 2013.

[0037] Specifically, the guide guard 301 is arranged in the vertical direction, which can guide and limit the up and down movement of the pallet. The positioning block 302 and the connecting rod 303 are provided with corresponding through holes that match the pin 304, which facilitates the fixed connection between the positioning block 302 and the connecting rod 303 through the pin 304. The position of the guide device 300 can be adjusted by changing the position of the pin 304.

[0038] It should be noted that the opening of the installation box 401 is set toward the frame body 100, and the blocking member 406 is a V-shaped structure. When the rotating cylinder 402 drives the adjusting block 404 to rotate counterclockwise, the adjusting block 404 drives the blocking member 406 to rotate clockwise through the connecting rod 405, and then extends one side of the blocking member 406 to the outside of the installation box 401, thereby supporting and fixing the pallet. On the contrary, the blocking member 406 cannot support and fix the pallet. At this time, the lifting device 500 can drive the pallet to move in the vertical direction.

[0039] Specifically, the lifting device 500 includes a mounting frame 501, a lifting cylinder 502 fixed on the mounting frame 501, and a lifting member 503 fixedly connected to the piston rod of the lifting cylinder 502. The lifting member 503 is a rectangular frame structure that can stably support the pallet. A linear bearing 504 is provided between the mounting frame 501 and the lifting member 503, which can enable the lifting cylinder 502 to remain stable during the process of pushing the pallet up and down.

[0040] Working principle: When stacking pallets, the destacking machine that is adaptable to a variety of pallets, after the pallet runs to the specified position on the chain conveyor 201, the jacking device 500 is lifted, and after reaching the required height, the jacking device 500 is locked, and the fork device 400 extends the blocking member 406 to hold the pallet, and then the next pallet is repeated The above operation can complete the stacking of the pallet, and after the stacking is completed, it is taken out from the other direction by a forklift; when depalletizing, the forklift places the stacked pallet at the specified position on the chain conveyor 201, and the jacking device 500 lifts the pallet and cooperates with the fork device 400 to hold the second-to-last layer of the pallet, and then the jacking device 500 returns to its position, and the penultimate layer of the pallet is placed on the chain conveyor 201 and transported out of the stacking area, and the next pallet is repeated The above operation can complete the depalletizing and placing. The destacking machine that can accommodate a variety of pallets has an advanced design and is easy to use. The guide edge guard 301, the positioning block 302, the connecting rod 303 and the latch 304 cooperate to form a guide device 300, and the rotating cylinder 402, the connecting rod 405 and the blocking member 406 cooperate to form a fork device 400. The guide device 300 and the fork device 400 are connected by bolts. When the guide device 300 is adjusted in position, the position of the fork device 400 also changes, so that a variety of pallets can be blocked. When storing pallets of different specifications, only the position of the latch 304 needs to be adjusted, and the adjustment is convenient. Moreover, the destacking machine that can accommodate a variety of pallets uses fewer components, reduces the complexity of the structure, and thus simplifies the installation process and improves the installation efficiency.

[0041] Finally, it should be noted that the above is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present utility model shall be included in the protection scope of the present utility model.
