AI Technical Summary
In the prior art, when a vertical clamping knife clamps the wooden board, due to the different hardness of the wooden slices and the width of the solid wood substrate, the clamping is inaccurate, the board is easily deviated and cannot be accurately cut, resulting in a defective rate of 3-5%.
A plate cutting system is designed, using a "eight" shape claw and tab structure, and the plate is accurate and corrected through gears and transmission mechanisms. The "eight" shape claws of the corrector can adapt to the thickness of the board, and the tabs can effectively resist the core of the board to ensure that the board is in a correct position before cutting.
Through this technical means, the genuine product rate of the board reaches more than 99%, solving the defective product rate problem caused by inaccurate cutting of the board in the prior art.

Abstract
Description
Technical Field
[0001] The utility model relates to a wood processing machine, in particular to a board cutting device. Background Art
[0002] The trimming of wood-based boards after forming is completed on the production line. The quality of trimming determines the qualified rate of products. The cutting positioning of the prior art is completed by clamping knives that move relatively on both sides of the cutting machine. The clamping knives are perpendicular to the edges of the boards. Since the middle of the wood-based board is a solid wood substrate glued by solid wood strips, and the upper and lower surfaces of the wood-based board are wood slices, the width of the wood slices is slightly larger than that of the solid wood substrate. The four sides of the formed wood-based board are uneven. At the same time, the hardness of the wood slices is also different. When the vertical clamping knives clamp the wood-based board, the clamping knives on both sides cannot accurately clamp onto the solid wood substrate due to the different hardness of the wood slices and the different widths protruding from the solid wood substrate. As a result, the board shifts and its position cannot be corrected, and it cannot be accurately cut. There are errors in the cut boards, resulting in 3-5% defective products. Summary of the Invention
[0003] The purpose of the utility model is to overcome the defects of the prior art and disclose a board cutting system that can reliably correct the board and avoid cutting errors of the board.
[0004] The technical solution of the utility model is: a board cutting system, including a pusher. There is a board table behind the pusher. There is a board on the board table. There is a board correction table behind the board table. There is a cutting table behind the board correction table. There is a receiving board table behind the cutting table. There are two groups of board correction positioning devices on the board correction table. The special feature is that: the board correction positioning device is provided with a gear. On the left and right sides of the gear, there are a first transmission mechanism and a second transmission mechanism that are meshed with the gear through racks. The second transmission mechanism is connected with a cylinder for pushing. A corrector is fixed on the first transmission mechanism and the second transmission mechanism. The said corrector is provided with a support part. On the support part, there are "eight"-shaped claws. A clamping tongue is horizontally arranged in the middle of the "eight"-shaped claws.
[0005] Further, the minimum opening width d of the "eight"-shaped claws is adapted to the thickness of the board.
[0006] Further, the clamping tongue is horizontally arranged.
[0007] Further, the clamping tongue is arranged in the exact middle of the "eight"-shaped claws.
[0008] Further, the length S of the clamping tongue ≥ the width of the rough edge of the board.
[0009] Further, the width of the clamping tongue is equivalent to the width of the "eight"-shaped claws.
[0010] The working principle of the present utility model is as follows: Under the push of the pusher, the sheet material completely enters the calibration table through the front guiding mechanism and rollers of the calibration table. After that, the travel switch sends a signal, and the controller controls the cylinder to retract, driving one side of the transmission mechanism to move towards the middle of the calibration table. The rack on the transmission mechanism drives the gear to rotate, and the gear simultaneously drives the other side of the transmission mechanism to move towards the middle of the calibration table. The transmission mechanisms on both sides drive the calibrator to synchronously clamp onto the sheet material on the calibration table. Since there will be irregular burrs on the sheet skin of the sheet material, the calibrator is provided with "eight"-shaped claws, which can accurately insert the side edges of the sheet material with burrs into the calibrator. As the calibrator further squeezes towards the sheet material, the tongue on the calibrator presses against the core of the sheet material. Since the side edge of the core is a regular straight edge and the compressive strength of the core is higher than that of the sheet skin, the two tongues can accurately clamp the sheet material. Since the two groups of sheet material calibration and positioning devices corresponding to the movement direction of the sheet material on the calibration table work synchronously, the movement position of the sheet material is accurately calibrated before it enters the cutting table. After the sheet material is calibrated, under the action of the time controller, the controller controls the cylinder to extend, and the transmission mechanism moves towards both sides of the calibration table, thereby driving the calibrator to release from both sides of the sheet material. The sheet material accurately enters the cutting for edge cutting under the push of the subsequent sheet material.
[0011] Due to the adoption of the above technical solution, the present utility model enables the qualified rate of the cut sheet material to reach more than 99%, solving the problem in the prior art that the vertical blade type calibrator clamps the irregular burrs on the sheet skin of the sheet material, resulting in inaccurate calibration position of the sheet material and a cutting defective rate of 3 - 5%.
