Description

Technical Field

[0001] The utility model relates to a wood processing device, in particular to a device for correcting and positioning a board. Background Art

[0002] The trimming of the formed wood board is completed on the production line, and the quality of the trimming determines the qualified rate of the product. The cutting positioning of the prior art is completed by the clamping knives that move relatively on both sides of the cutting machine. The clamping knives are perpendicular to the edge of the board. Since the middle of the wood board is a solid wood substrate glued by solid wood strips, and the upper and lower surfaces of the wood 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 board are uneven. At the same time, the hardness of the wood slices is also different. When the vertical clamping knives clamp the wood 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 the position cannot be corrected, and the cutting cannot be accurately performed. There are errors in the cut board, and 3-5% of the products are defective. Summary of the Invention

[0003] The purpose of the utility model is to overcome the defects of the prior art and disclose a board correction positioner and its device that can reliably correct the board and avoid cutting errors of the board.

[0004] One of the technical solutions of the utility model is: a board correction positioner, characterized in that: it is provided with a support part, an "eight"-shaped claw is arranged on the support part, and a clamping tongue is arranged in the middle of the "eight"-shaped claw.

[0005] Another technical solution of the utility model is: a board correction positioning device, including a gear, a first transmission mechanism and a second transmission mechanism that are arranged on the left and right sides of the gear and meshed with the gear through racks. The second transmission mechanism is connected with a cylinder for pushing, and a board correction positioner fixed on the first transmission mechanism and the second transmission mechanism. The special feature is that: the said board correction positioner is provided with a support part, an "eight"-shaped claw is arranged on the support part, and a clamping tongue is arranged in the middle of the "eight"-shaped claw.

[0006] Further, the minimum opening width d of the "eight"-shaped claw is adapted to the thickness of the board.

[0007] Further, the clamping tongue is arranged horizontally.

[0008] Further, the clamping tongue is arranged in the exact middle of the "eight"-shaped claw.

[0009] Further, the length S of the clamping tongue ≥ the width of the rough edge of the board.

[0010] Further, the width of the tongue is equivalent to the width of the "eight"-shaped claw.

[0011] Since the above technical solutions are adopted in the present utility model, the positioner plate can be accurately calibrated, and the qualified rate of the cut plates can reach at least 99%. It solves the problem that in the prior art, the irregular burrs of the plate skin on the plate clamped by the vertical blade type calibrator lead to inaccurate calibration position of the plate, resulting in a cutting defective rate of 3-5%.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] For a clear understanding of the present utility model, the following Figures 1-5 further describes the present utility model in terms of specific embodiments.

[0019] Embodiment 1: A plate calibration positioner is provided with a support part 18, an "eight"-shaped claw 17 is arranged on the support part, and a tongue 14 is arranged in the middle of the "eight"-shaped claw.

[0020] Embodiment 2: A plate calibration positioner is provided with a support part 18, an "eight"-shaped claw 17 is arranged on the support part. The minimum opening width d of the "eight"-shaped claw is adapted to the thickness of the plate. A tongue 14 is arranged in the middle of the "eight"-shaped claw. The tongue is arranged horizontally and is located exactly in the middle of the "eight"-shaped claw. The length S of the tongue ≥ the width of the plate burr, and the width of the tongue is equivalent to the width of the "eight"-shaped claw.

[0021] Embodiment 3: A sheet metal correction and positioning device, comprising a gear 9, a first transmission mechanism 7 and a second transmission mechanism 21 disposed on the left and right sides of the gear 9 and meshing with the gear 9 through racks. The second transmission mechanism 21 is push-connected to a cylinder 8, and a corrector 12 fixed on the first transmission mechanism 7 and the second transmission mechanism 21. The said corrector 12 is provided with a support portion 18, an "eight"-shaped claw 17 is provided on the support portion 18, and a locking tongue 14 is horizontally provided in the middle of the "eight"-shaped claw 17.

[0022] Embodiment 4: A sheet metal correction and positioning device, comprising a gear 9, a first transmission mechanism 7 and a second transmission mechanism 21 disposed on the left and right sides of the gear 9 and meshing with the gear 9 through racks. The second transmission mechanism 21 is push-connected to a cylinder 8, and a corrector 12 fixed on the first transmission mechanism 7 and the second transmission mechanism 21. The said corrector 12 is provided with a support portion 18, an "eight"-shaped claw 17 is provided on the support portion 18. The minimum opening width d of the "eight"-shaped claw is adapted to the thickness of the sheet metal. A locking tongue 14 is horizontally provided in the middle of the "eight"-shaped claw 17. The locking tongue is provided in the exact middle of the "eight"-shaped claw and is horizontally arranged. The length S of the locking tongue is ≥ the width of the rough edge of the sheet metal, and the width of the locking tongue is equivalent to the width of the "eight"-shaped claw.

[0023] The working principle of the present utility model is as follows: The sheet material 2 is pushed by the pusher 1 and completely enters the correction table 11 through the front guiding mechanism 3 and the roller 4 of the correction table 11. After that, the travel switch emits a signal, and the controller controls the cylinder 8 to retract, driving the first transmission mechanism 7 on one side to move towards the middle of the correction table 11. The rack on the transmission mechanism drives the gear 9 to rotate, and the gear 9 simultaneously drives the second transmission mechanism 21 on the other side to move towards the middle of the correction table 11. The transmission mechanisms on both sides drive the corrector 12 to synchronously clamp the sheet material 2 on the correction table 11. Since the sheet material skin 20 on the sheet material 2 has irregular burrs, the corrector 12 is provided with "eight"-shaped claws 17, which can accurately insert the side edge of the sheet material 2 with burrs into the corrector 12. As the corrector 12 further squeezes towards the sheet material 2, the tongue 14 on the corrector 12 abuts against the sheet material core 19 of the sheet material. Since the side edge of the sheet material core 19 is a regular straight edge and the compressive strength of the sheet material core 19 is higher than that of the sheet material skin 20, the two tongues 14 can accurately clamp the sheet material 2. Since the two sets of sheet material correction and positioning devices corresponding to the front and back in the movement direction of the sheet material on the correction table 11 work synchronously, the movement position of the sheet material is accurately corrected before it enters the cutting table 10. After the sheet material is corrected, under the action of the time controller, the controller controls the cylinder 8 to extend, and the transmission mechanism moves towards both sides of the correction table 11, so as to drive the corrector 12 to release from both sides of the sheet material. The front sheet material accurately enters the cutting table 10 for edge cutting under the push of the subsequent sheet material. The present utility model can accurately correct and position the sheet material, so that the qualified rate of the cut sheet material reaches more than 99%, solving the problem in the prior art that the vertical blade type corrector clamps the irregular burrs of the sheet material skin on the sheet material, resulting in inaccurate sheet material correction position and a cutting defective rate of 3-5%.
