[0020] The technical scheme of the utility model will be further specifically explained below by way of examples in conjunction with the drawings.

[0021] As Figures 1-2 shown, an adjustable fork distance disassembling and stacking tray machine comprises a rack 1, two shifting forks 2 are arranged on both sides of the rack 1, a lifting structure a for driving the shifting forks 2 to move up and down and a telescopic structure b for driving the shifting forks 2 to move horizontally and telescopically towards the middle part of the rack 1, the shifting fork 2 comprises a fork part 21 extending into a tray fork hole and arranged in a plate shape and a fixing part 22 for fixing the shifting fork 2, a top block 23 that can move up and down is arranged at a position close to the end of the top surface of the fork part 21, a push block 24 that is vertically arranged and in transmission connection with the bottom of the top block 23 is arranged on the side of the top block 23 facing the fixing part 22, when the shifting fork 2 extends into the tray fork hole, the push block is pressed, the top block 23 moves up synchronously to lift the tray, the top surface of the top block 23 is flush with the top surface of the fork part 21, and the push block 24 is above the adjacent side of the top block 23; two shifting forks are arranged on both sides of the rack, the lifting movement and the telescopic movement of the shifting forks are driven by the driving of the lifting structure and the telescopic structure, the telescopic structure can drive the shifting forks to move into the fork hole of the tray and lift multiple trays by the lifting structure, so as to disassemble and stack the trays, the lifting structure can be a combination structure of a chain wheel and a motor to drive the shifting forks to move up and down, or can be a structure of a pneumatic cylinder to drive the shifting forks to move up and down, the telescopic structure can be a structure of a motor driving a push rod to drive two shifting forks to move telescopically synchronously, or can be a structure of a pneumatic cylinder pushing two shifting forks to move telescopically synchronously.

[0022] During the process that the shifting fork extends into the tray fork hole, the shifting fork gradually enters the tray fork hole, and the top block also gradually enters the fork hole. After the top block completely enters the fork hole, the tray side wall contacts the push block and exerts pressure on the push block, causing the push block to move. The push block synchronously drives the top block through the transmission structure, causing the top block to move upward and push the tray, so that the bottommost tray is separated from all the remaining trays above it, thereby enabling the bottommost tray to be transported. This structure does not need a lifting structure to drive the shifting fork, but only needs an extension structure to drive the shifting fork, which can separate the bottommost tray from all the remaining trays above it, effectively reducing the driving and use of the device, reducing the driving steps, and synchronously pushing the tray during the extension and retraction of the shifting fork, ensuring the immediacy of the tray pushing, improving the reaction speed of the device action, and reducing device wear and saving energy.
