Description

Technical Field

[0001] The invention relates to the technical field of automatic stacking equipment, in particular to an automatic stacking device for density board production. Background Art

[0002] Density board is a man-made board made of wood cellulose material and synthetic resin or other suitable adhesives, which are pressed under heating and pressure conditions. Density board is mainly used in furniture manufacturing, building decoration and packaging industries. During the production process of density board, it is usually necessary to paste kraft paper on its surface, which mainly plays the role of enhancing protection, improving appearance and moisture-proofing. After the density board is pasted with kraft paper, it needs to be stacked using an automatic stacking device after production is completed. However, the existing automatic stacking device has certain defects during use.

[0003] 1. In the process of pasting kraft paper on the existing density board, the conveying device is mainly used to continuously convey the density board to the roller press, and then the rolling effect of the roller press is used to paste the kraft paper on the density board. Since the kraft paper is continuous and the density board is also continuously conveyed, the continuous kraft paper needs to be cut. During the cutting process, the board and the conveying device are prone to slippage, which makes it easy for the edges to break during the cutting process. After cutting, the stacking robot is used for stacking, and the density board pasted with kraft paper needs to be positioned before stacking. The positioning action includes blocking and limiting and centering positioning. The blocking and limiting and centering positioning actions in the existing equipment are independent of each other and are performed one after another, which is cumbersome to operate.

[0004] 2. When palletizing existing density boards, they are usually adsorbed by a robot with a suction cup, and then moved to a designated position for palletizing. However, when the density boards with kraft paper are palletized by suction cups, the suction cups are usually directly adsorbed on the side of the density boards with kraft paper, which may cause the kraft paper and the density boards to fall off. If the density boards are directly palletized after the kraft paper is affixed, the edges of the density boards may easily become debonded and warped. Summary of the invention

The support, at this time, start the No. 1 hydraulic cylinder 5, the No. 1 hydraulic cylinder 5 drives the fixed frame 3 to descend until the mounting plate 925 moves to the bottom of the density board. When the mounting plate 925 moves downward, the bottom of the one-way flip plate 924 contacts the edge of the density board, so that the one-way flip plate 924 flips upward. When the mounting plate 925 moves to the bottom of the density board, the one-way flip plate 924 returns to the horizontal position. In this process, as the fixed frame 3 descends, the fixed pulley 431 and the mounting block 432 are driven to move downward, thereby pulling the steel rope 433, and synchronously driving the movable plate 414 and the guide slide rail 422 thereon to move in a centering manner, and then driving the slider 428 and the clamping claw 423 and the clamping block 429 thereon to move in a centering manner, and using the clamping block 429 to clamp and fix the side of the density board. At the same time, the telescopic rod 913, the mounting plate 925 and the one-way flip plate 924 are driven to move in the center, and the one-way flip plate 924 and the mounting plate 925 are used to clamp and fix the density board in a bottom supporting manner. The clamping stability is strong, and when the clamping block 429 is clamped, the connecting rod 923 is in a horizontal state, and when the connecting rod 923 is in a horizontal state, the clamping block 429 passes through between the two connecting rods 923, and is closer to the edge of the density board than the connecting rod 923, which is convenient for clamping the density board. After clamping, the stacking robot 6 moves the density board to the specified position, and then releases the clamping to realize automatic stacking of the density board. When the position of the clamping claw 423 needs to be adjusted according to the size of the board, the locking screw 424 is turned to loosen the crimping fixation of the guide rail 422 by the clamping block 427.At this time, slide the slider 428 along the guide rail 422. After sliding to the specified position, turn the locking screw 424 in the opposite direction, and use the clamping block 427 to clamp and fix the guide rail 422 again, so as to complete the position adjustment of the clamping claw 423. When the output end of the No. 1 hydraulic cylinder 5 contracts, under the elastic force of the No. 2 spring 412, the movable plate 414 is driven to move apart, thereby driving the clamping claw 423 to move apart, and the clamping claw 423 is reset. The length of the telescopic rod 913 is adjusted by the thread, which is convenient for adjusting the length of the telescopic rod 913 according to the size of the density board. After stacking, the output end of the No. 3 hydraulic cylinder 911 rises, and the locking of the telescopic rod 913 is released. Under the elastic force of the No. 1 spring 922, the rolling deformation mechanism 9 is reset to the initial state.

[0048] Working principle: During use, the present invention first uses the roller conveyor 1 to convey the density board with kraft paper pasted on it from left to right, and then uses the material blocking and limiting mechanism 2 to block and limit the density board. The material blocking and limiting mechanism 2 simultaneously drives the centering positioning mechanism 8 to move in the center, thereby realizing the clamping and positioning of the density board, ensuring the stable clamping of the density board, and avoiding shaking during slitting. Then, the automatic slitting mechanism 7 is used to cut from back to front to cut the kraft paper on the density board, thereby realizing the integrated linkage of the material blocking and limiting mechanism 2 and the centering positioning mechanism 8. After the positioning and slitting are completed, the rolling deformation mechanism 9 is used to roll the top edge of the density board to avoid the problem of degumming, and the rolling deformation mechanism 9 and the clamping claw 423 form an L shape, which is convenient for bottom support and side clamping of the density board, thereby improving the clamping stability. After clamping is completed, the stacking robot 6 is used to move the clamped density board to the specified position for automatic stacking, thereby realizing automatic stacking and stacking of the density board with kraft paper pasted on it.
