[0002] Furniture is made up of boards. Different types of boards also lead to differences in materials and prices. They can be divided into low-density fiberboard, medium-density fiberboard, high-density fiberboard, solid wood particle board, solid wood board, etc. The boards are processed by equipment to form a whole board, and then stacked, placed and packed for delivery to the processing plant. The processing plant selects boards according to customer customization requirements for prefabrication to facilitate workers to assemble the finished products.

[0040] Then, the stacked plates can be placed between the first side baffle 32 and the second side baffle 35 by the support of the support plate 373, and the rear side is blocked and limited by the rear baffle 363;

[0041] The motor 47 on the base 46 in the conveying structure 4 can also be driven, through the linkage of the transmission wheel 48 and the transmission belt 49, to drive one of the shaft rods 42 to rotate on the shaft frame 41, and then drive the conveyor belt 44 between the multiple pulleys 43 to rotate in the opposite direction to convey the plate to the left; and then the single plate is placed on the right end of the conveyor belt 44 and conveyed to the left; by controlling the lifting arm 372 to drive the support plate 373 to descend below the conveyor belt 44, the plate can be moved between the first side baffle 32 and the second side baffle 35, and then the first hydraulic cylinder 30 is contracted, and the first side baffle 32 is driven to descend by the auxiliary force of the limit column 31, and then the third hydraulic cylinder 381 in the clamping assembly 38 is driven to extend and the top plate 382 installed by the third bolt 383 is moved to the left to clamp the plate on the first side baffle 32; then the first hydraulic cylinder 30 is raised to a certain height to receive the second plate, and the operation is repeated to realize automatic stacking and placing of plate materials for stacking use;

[0042] When unloading is required, since the plate is located between the first side baffle 32 and the second side baffle 35, and the bottom is supported by the support plate 373 located above the conveyor belt 44; then, according to the thickness of the plate, the second hydraulic cylinder 371 can be controlled to drive the support plate 373 to descend to a height of a corresponding thickness, and then the first hydraulic cylinder 30 can be controlled to contract and drive the entire plate to descend, so that the support plate 373 descends to below the conveyor belt 44, and then the bottom plate is attached to the conveyor belt 44. At this time, the second plate from the bottom to the top is lowered by a corresponding thickness because the support plate 373, and then the second plate is still displaced between the first side baffle 32 and the second side baffle 35 under the cover of the first plate, and at the same time, the tightening assembly 38 is driven to tighten and limit the remaining plates to prevent the bottom plate from being moved out and falling due to gravity and causing damage to the conveyor belt 44;

[0043] Then, the driving block 45 is driven by the conveyor belt 44 to move the toggle block 45 from the left side of the first side baffle 32 to the right, pushing the plate out from under the first side baffle 32 and the second side baffle 35, and conveying it to the right along with the conveying structure 4, completing the single-piece unloading; after the single-piece plate is moved away, the support plate 373 can be driven to rise and lift it;

[0044] When the plate moves to the right along with the conveying structure 4, the right side of the conveying structure 4 can be provided with corresponding processing equipment, such as Figure 1The cutting machine body 6 shown in the arrangement can drive the second electric slide rail 51 in the adjustment structure 5 to drive the relatively inclined support arm 52 to move relatively when the plate has not separated from the conveying structure 4 and enters the processing table of the cutting machine body 6. The support arm 52 is connected with the movable connection to perform reverse flipping under force, thereby driving the load-bearing plate 53 to rise to a certain height, prompting the top wheel 54 to rise and extend from between the conveyor belts 44 to above the conveyor belt 44, so that the plate can be raised, and the electric push rod 552 on the push frame 551 in the pushing unit 55 is extended, and the front and rear side walls of the plate are forced by the push claw 553 (the length and installation position of the push claw 553 are set according to actual needs). The plate can be moved forward and backward through the top wheel 54 to adjust the position of the plate relative to the cutting machine body 6, and the plate can be adjusted according to the cutting width. Finally, the top wheel 54 is lowered and reset, and the plate is moved to the right through the conveying structure 4 to be fed to the processing equipment.
