Description

Technical Field

[0001] The utility model belongs to the technical field of wood board processing, and in particular relates to an edge cleaning machine for fast and accurate positioning of wood boards. Background Art

[0002] At present, the most commonly used methods for wood board edge cleaning on the market are manual cutting and equipment cutting. With the progress of the times and the development of technology, manual cutting has gradually been replaced by equipment. The existing equipment cuts wood boards by manually placing the cut wood boards on the feeding mechanism, and then the clamping mechanism places the wood boards in the designated position and enters the cutting mechanism for edge cleaning.

[0003] Chinese patent document publication number CN219618016U discloses a wood board edge cleaning machine, which includes a feeding mechanism, a material rack, a clamping mechanism, a photographing and identifying mechanism, a pressing mechanism, a first transmission roller mechanism and a sawing mechanism. The photographing and identifying mechanism is arranged above the material rack, and the image acquisition end of the photographing and identifying mechanism corresponds to the material rack. The feeding end of the first transmission roller mechanism is arranged on one side of the clamping mechanism, and the discharging end of the first transmission roller mechanism corresponds to the feeding end of the sawing mechanism. The pressing mechanism is arranged above the first transmission roller mechanism and is used to press down and stabilize the material. The clamping mechanism is used to transfer the material from the material rack to the first transmission roller mechanism, and the first transmission roller mechanism is used to transfer the material to the sawing mechanism for cutting. However, the above-mentioned wooden board edge cleaning machine adopts a clamping mechanism to correct the offset angle of the wooden board. When the wooden board is long, the wooden board is easy to shake on the clamping mechanism, and the wooden board will also bend, resulting in low detection accuracy of the camera recognition mechanism. Moreover, the clamping claw assembly of the clamping mechanism will cause damage to the wooden board and produce clamping marks when the clamping force is large. In addition, the clamping mechanism clamps the wooden board upward through the lower clamping plate. When the wooden board is loosened, it is easy to cause the corrected wooden board to move inaccurately. Moreover, the steering motor group and the sliding guide rail assembly need to work together to realize the angle correction and movement of the wooden board. The operation process is complicated and the work efficiency is low. Utility Model Content

The side plates 84 are arranged on both sides of the sliding frame 83. The bottom roller 85 and the first pressure roller 86 are arranged between the two side plates 84, and the first pressure roller 86 is located above the bottom roller 85. The conveying motor 87 is fixed on the side plate 84 and connected to the bottom roller 85. The linear guide rail 88 is arranged between the mounting plate 81 and the sliding frame 83.

[0030] The board to be cleaned is transmitted to the positioning mechanism 3 through the feeding mechanism 2. The initial positions of the bottom roller 85 and the first pressure roller 86 of the positioning mechanism 3 are located at the downstream end of the feeding mechanism 2. After the board is transmitted to the positioning mechanism 3, the servo motor drives the bottom roller 85 to continue to transmit the board for a certain distance. When the board is located below the camera mechanism 6 as a whole, it stops and takes a photo, or the board is moved to the middle position through the linear guide 88, and then the camera mechanism 6 takes a photo of the board. The photo taken is processed by the camera mechanism 6 to identify whether the board is offset and whether the center line is aligned with the center line of the sawing mechanism 4. If it is not aligned, the angle is adjusted by controlling the two linear guides 88. After the correction is completed, the transmission motor 87 is actuated to transmit it to the sawing mechanism 4 of the next process. The sawing mechanism 4 performs edge cleaning on the board. After the edge cleaning is completed, the board is transmitted out through the discharging mechanism 5. The industrial control mechanism 7 realizes the control of each mechanism.

[0031] The device adopts a set of feeding mechanism 2 and linear conveying mechanism 8 to cooperate, which improves the corresponding speed of the action and has low equipment cost; the linear conveying mechanism 8 quickly adjusts the position after receiving the instruction, and then the transmission motor 87 drives the conveyor to the sawing mechanism 4, ensuring that the wood board cutting process is more stable and accurate, and improving the product qualification rate; the camera mechanism and the photo recognition mechanism determine the width and angle accurately, ensuring the material cutting accuracy and improving the product quality.

[0032] Furthermore, connecting plates 861 and torsion springs 862 are provided on both sides of the first pressure roller 86, one end of the connecting plate 861 is respectively connected to the inner rotating shafts 841 of the two side plates 84, the first pressure roller 86 is connected to the other ends of the connecting plates 861 on both sides, a fixing pin 863 is provided in the middle of the connecting plate 861, the torsion spring 862 is provided on the fixing pin 863, and the two ends are respectively abutted against the upper side of the rotating shaft 841 and the shaft of the first pressure roller 86.

[0033] The first pressure roller 86 has a certain elastic downward pressure by setting a connecting plate 861 and a torsion spring 862, which plays a stabilizing role, reduces or avoids the position deviation problem of the wooden board caused by vibration, ensures the placement accuracy of the wooden board, and thus ensures that the wooden board cutting process is smoother and more accurate, thereby improving the product qualification rate.

[0034] Furthermore, an opening 864 is provided at the end of the first pressure roller 86 of the connecting plate 861, and the opening 864 is connected with a screw rod; and an anti-slip pattern is provided on the surface of the bottom roller 85.

[0035] The opening 864 of the connecting plate 861 facilitates the installation of the first pressing roller 86 .

[0036] Furthermore, the sawing mechanism 4 is provided with a conveying roller 41, a second pressure roller 42, a conveying motor 43, a sawing roller 44 and a sawing motor, the sawing roller 44 is arranged across the frame 1, the sawing motor is fixed on the frame 1 and connected to the sawing roller 44; the upstream and downstream sides of the sawing roller 44 are respectively provided with conveying rollers 41 connected to the frame 1, the conveying motor 43 is fixed on the frame 1 and linked to the conveying roller 41, and the second pressure roller 42 is arranged above the conveying roller 41.

[0037] The conveying roller 41 and the second pressure roller 42 provide power for the wood board to be transmitted on the sawing mechanism 4, and provide a pressing force to avoid deviation during the sawing process, thereby ensuring that the wood board cutting process is smoother and more accurate, and improving the product qualification rate.

[0038] Furthermore, at least two conveying rollers 41 are provided on the upstream and downstream sides of the sawing roller 44 , and at least one conveying roller 41 on the upstream side and the downstream side is connected to a conveying motor 43 .

[0039] Setting multiple roots ensures a smoother cutting process.

[0040] Furthermore, the feeding mechanism 2 is arranged on one side of the upstream end of the positioning mechanism 3 .

[0041] Setting the feeding mechanism 2 only on one side can reduce the cost of the equipment; in addition, when the camera mechanism 6 detects that the wooden board cannot be sawed, the notch position on the other side can be returned from the other side, moved to the notch position by the linear mechanism, and then reversed and returned by the transmission motor 87.

[0042] Furthermore, the feeding mechanism 2 and the discharging mechanism 5 are conveyor belts or conveyor rollers.

[0043] Furthermore, the feeding mechanism 2 is a primary feeding mechanism 2.

[0044] The feeding mechanism 2 is a first-level feeding mechanism 2, which directly conveys the wooden board to the material rack, shortening the conveying and transfer time and improving efficiency;

[0045] Furthermore, the conveying motor 87 is a servo motor, which can more accurately control the position of the moving wooden board.
