Description

Technical Field

[0001] This utility model relates to the field of artificial board machinery technology, specifically to a cutting device for a board assembly and laying line. Background Technology

[0002] The plywood production process includes veneer preparation, gluing and assembly, pressing, edge trimming, and sanding. After the plywood is assembled on the board laying line, it needs to enter the pressing process for pressing treatment.

[0003] Currently, plywood is usually not trimmed after assembly, resulting in burrs at the edges. During operations such as stacking the plywood blanks, these burrs break off and form wood chips that scatter on the surface of the blanks. After subsequent pressing processes, these chips can cause indentations on the surface of the blanks, leading to a reduction in the quality of the boards and an increase in production costs.

[0004] Secondly, after the plywood is assembled on the board laying line, it is cut into blanks and then stacked into piles before entering the pressing device for pressing. During the transfer and transportation process, problems such as blank breakage and edge loosening may occur due to vibration or bumps, which reduces the quality of the board. Utility Model Content

The first pressure plate 114, in conjunction with the cutting table 12, presses one side of the board blank. The cutter holder 13 continues to descend... A first cutting blade 18 cuts the edge of the slab, a second cutting blade 19 cuts off the waste edge, and a second pressure plate 116 presses down the cut waste edge and removes it from the slab. The waste edge comes out through the discharge port of the cutting table 12. The conveying mechanism 3, together with the conveyor belt, continues to convey the slab. The cut slab is conveyed away, and the uncut slab is moved to the cutting table 12 for cutting.

[0043] In using this utility model, a board-laying conveyor belt is provided on the left side of the conveying mechanism 3 and runs synchronously with it. Workers stack and lay boards on the board-laying conveyor belt to form a board blank. The board blank is conveyed to the conveying mechanism 3 via the board-laying conveyor belt. The side of the board blank moves to the cutting table 12. The conveying mechanism 3 stops conveying, the motor 28 starts, the second gear 212 rotates, driving the second rack 214 to descend, which in turn drives the pressure frame 26 to pre-press the board blank. The hydraulic cylinder 17 drives the cutter holder 13 to descend. The first pressure plate 114, in conjunction with the cutting table 12, presses one side of the board blank. The cutter holder 13 continues to descend, the first cutting blade 18 cuts the edge of the board blank, and the second cutting blade 19 cuts off the waste edge. The second pressure plate 116, in conjunction with the cut... The scrap edges are pressed down and detached from the slab.

The conveying mechanism 3, together with the conveyor belt, continues to transport the slab. The cut slab is transported away, and the uncut slab is moved to the cutting table 12 for cutting. The pre-pressing mechanism 2 pre-presses the slab, which can work with the edge-cutting mechanism 1 to press the slab as a whole, making the edges of the cut slab neater. This facilitates the subsequent edge-cutting operation after pressing. The edge-cut slab enters the cutting device to be cut into slabs of appropriate size and stacked for the next processing step. Through the pre-pressing of the slab, the slab can be made denser, avoiding problems such as slab breakage and edge collapse caused by vibration or bumps during subsequent transportation and loading, and further improving the quality of the product.

The mesh belt assembly 32 includes a mesh belt, and a plurality of limiting plates 33 are provided on the rear side of the mesh belt. The setting of the limiting plates 33 can facilitate the operator to lay the board blank. When laying the board, the operator only needs to align the far end of the board with the limiting plate 33 to align one side of the board blank. With this setting, only one side of the board blank needs to be cut.

[0045] Specifically, a support plate 34 is provided at the bottom of the conveyor belt frame 31. The support plate 34 is correspondingly arranged at the lower part of the upper mesh belt. When the pressure frame 26 pre-presses the blank, the support plate 34 supports the bottom of the blank, which makes the pre-pressing effect better, supports the mesh belt and can improve the service life of the mesh belt.

[0046] Example 4: The conveyor belt of the conveying mechanism 3 is a mesh belt. Edge-cutting mechanisms 1 are installed on both the front and rear sides of the conveying mechanism 3.

When using this invention, a board-laying conveyor belt is installed on the left side of the conveying mechanism 3 and runs synchronously with it. Workers stack and lay boards on the board-laying conveyor belt to form board blanks. The board blanks are conveyed to the conveying mechanism 3 via the board-laying conveyor belt. The two sides of the board blanks move to the two cutting tables 12 on both sides. When the conveying stops, the hydraulic cylinder 17 drives the cutter holder 13 to descend. The first pressure plate 114, together with the cutting table 12, presses one side of the blank. The cutter holder 13 continues to descend, and the first cutting blade 18 cuts the edge of the blank. The second cutting blade 19 cuts off the waste edge. The second pressure plate 116 presses down the cut waste edge and removes it from the blank. The waste edge comes out through the discharge port of the cutting table 12. The conveying mechanism 3, together with the conveyor belt, continues to convey the blank. The cut blank is conveyed away, and the uncut blank is moved to the cutting table 12 for cutting. The cut blank enters the cutting device to be cut into blanks of appropriate size and stacked for the next processing step.

[0047] Cutting both the front and back sides of the slab ensures that the edges of the slab are neat after pressing. After pressing, there is no need to saw the edges, and it can directly enter the next process, thereby reducing one edge-cutting process and reducing production costs.
