Description

Technical Field

[0001] The invention relates to the technical field of wood turning, in particular to a plate cutting device with a CAD comparison and calibration function. Background Art

[0002] Cut wood boards refer to the process where the factory cuts, flattens, and straightens the imported logs according to the needs, and makes them into boards of various specifications, removing a large amount of impurities and irregular shapes, and then sells them to customers after pre-processing. A plate cutting device described in the patent application with announcement number CN213352761U comprises a frame, a conveying unit, a positioning and guiding unit, a side guard unit and a cutting unit; the conveying unit is arranged on the frame for conveying the plate; the positioning and guiding unit comprises a mounting table, a pushing mechanism and a guide plate mechanism; the mounting table is arranged on one side of the frame, the pushing mechanism is arranged on the mounting table, and the output end of the pushing mechanism faces the conveying unit; the side guard unit is arranged on the other side of the frame and opposite to the positioning and guiding unit; the guide plate mechanism is connected to the output end of the pushing mechanism, and the output end of the pushing mechanism drives the guide plate mechanism to translate above the conveying unit; the cutting unit is arranged on the frame, and the cutting unit is located at the rear end of the conveying direction of the conveying unit; When cutting wood in the cold northern regions, as the temperature drops, the water in the wood cell walls begins to freeze, causing the wood to shrink and its density to increase.

In addition, long-term exposure to low temperatures reduces the toughness of the wood, making it relatively brittle and susceptible to shock and vibration. This brittleness may cause the wood to crack and break more easily during the cutting process, which will also increase the difficulty and error of cutting. Summary of the invention

[0012] The present invention provides a plate cutting device with CAD comparison and calibration function. It has the following beneficial effects: 1. The present invention sets a focused irradiation mechanism so that the heat radiation can be concentrated to preheat the position to be cut. By heating, the shrinkage and deformation of the wood during the cutting process can be slowed down, thereby improving the accuracy and stability of cutting. In addition, heating may reduce the hardness of the wood, making it softer and easier to cut, which helps to improve cutting efficiency, reduce tool wear, and avoid the problem of accuracy loss under the reference CAD comparison and calibration.

[0013] 2. The present invention sets a focusing irradiation mechanism. As the high-precision cutting head descends, the opening and closing plate will continuously rotate under the hinged rotation of the rotating rod, and keep the infrared heat radiation lamp always facing the processing position of the high-precision cutting head to complete the heating work for the area. When the position is changed by continuous lifting and cutting, the heat radiation will not lose a lot of heat energy due to the wrong irradiation position during the frequent lifting and lowering process due to the fixed angle, resulting in poor heating effect and unstable heating effect.

[0014] 3. The present invention sets a focusing irradiation mechanism. When the heating efficiency of heat radiation is not enough to heat up the wooden board in the area around the high-precision cutting head, the heat absorbed by the connecting plate is quickly released to the wooden board through contact with the wooden board, thereby completing the heating effect of the wooden board with a lower temperature, and achieving as much as possible the stable heating effect on the wooden board under various working conditions, thereby further avoiding the adverse situation of low temperature of the wooden board.

[0015] 4. The present invention sets a focusing and irradiating mechanism. When the sliding rod slides in the hollow sliding groove, the positional relationship between the sliding rod and the scale groove can be observed. The farther the sliding rod is from the connecting sleeve, the more the hinged rod is pushed to rotate. This also means that the thicker the plate processed by the bottom of the high-precision cutting head, the deeper the penetration depth. This makes it easier for staff to quickly judge the high and low position status of the high-precision cutting head at this time, as well as the approximate thickness of the plate during cutting, which is more convenient for subsequent operations and processing.

[0016] 5. The present invention sets an irradiation adjustment mechanism. When the high-precision cutting head rises and moves away from the wooden board, the telescopic plate blocks the infrared heat radiation lamp less. This avoids the situation where, when the high-precision cutting head descends to cut the wooden board, several infrared heat radiation lamps of the heat radiation mechanism rotate simultaneously to heat the surface of the wooden board at the processing position, which eventually leads to excessive temperature and internal expansion of the wood, thus affecting the cutting accuracy. When the high-precision cutting head is away from the wooden board, the infrared heat radiation lamp is fully opened to heat the wooden board by heat radiation, so as to ensure sufficient heating effect at a long distance. The invention also adapts to different working conditions and takes corresponding heating measures to prevent accidents. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0019] Example 1: Please refer to Figure 1-4 The present invention provides a technical solution: a plate cutting device with CAD comparison and calibration function, comprising a cutting machine 1, a first slider 5 is arranged on the top of the cutting machine 1, a second slider 6 is arranged on the top of the first slider 5, a cutting machine 7 is arranged on one side of the second slider 6, a high-precision cutting head 8 is fixedly connected to the output end of the cutting machine 7, a wooden piece 9 is placed on the top of the cutting machine 1, and a heat radiation mechanism 2 is arranged on the outer wall of the cutting machine 7; The heat radiation mechanism 2 comprises: The connecting sleeve 201 is a circular ring structure, the inner wall of the connecting sleeve 201 is fixedly connected to the outer wall of the cutting machine 7, and an opening and closing plate 202 is provided at the bottom of the connecting sleeve 201. The connecting sleeve 201 is used to connect the opening and closing plate 202 and the cutting machine 7; The infrared heat radiation lamp 203 is a square plate-shaped structure. The infrared heat radiation lamp 203 is fixedly connected to the bottom of the opening and closing plate 202. A rotating rod 204 is fixedly connected to one side of the opening and closing plate 202. The opening and closing plate 202 is rotatably connected to the bottom of the connecting sleeve 201 through the rotating rod 204 on one side. The infrared heat radiation lamp 203 is used to heat the wood; When in use, first use CAD software to draw a drawing of the plate to be cut, and then transfer the drawing to the control system of the cutting machine 1 through USB, network connection, etc.; Comparison and calibration: After receiving the drawing, the control system of the equipment will automatically compare and calibrate to match the design size on the drawing with the size of the actual plate to ensure the cutting accuracy; Cutting and slitting: After the comparison and calibration, the equipment will automatically cut and slitting according to the design on the drawing. During this process, the equipment uses a slitting machine 1 and a precise control system to ensure the accuracy and efficiency of cutting; When cutting, the first slider 5 moves horizontally on the top of the cutting machine 1 under the control of the system, driving the second slider 6 to move, and the second slider 6 controls the cutting machine 7 to move longitudinally on the surface of the first slider 5, and drives the cutting machine 7 to move up and down through the second slider 6, so that the cutting machine 7 can move and rise freely, and drive the high-precision cutting head 8 at the bottom to complete the cutting of the wooden board below; When cutting wood boards in areas with low ambient temperatures or in winter, the infrared heat radiation lamp 203 is turned on in advance before the board needs to be cut, so that the radiant heat energy emitted outward by the infrared heat radiation lamp 203 is transferred to the wood below, and through the inclined surface of the opening and closing plate 202, the heat radiation is concentrated to preheat the position to be cut. As the temperature decreases, the water in the cell wall of the wood begins to freeze, causing the volume of the wood to shrink and the density to increase. This shrinkage may cause the size of the wood to change, thereby affecting the accuracy of the cutting. When exposed to low temperatures for a long time, the wood may deform, such as bending and twisting, which will also increase the difficulty and error of the cutting. By heating, the shrinkage and deformation of the wood during the cutting process can be slowed down, thereby improving the accuracy and stability of the cutting. In addition, heating may reduce the hardness of the wood, making it softer and easier to cut. This helps to improve cutting efficiency, reduce tool wear, and thus avoid the problem of accuracy loss under the reference CAD comparison and calibration. Example 2: Please refer to Figure 1-10 On the basis of the first embodiment, the present invention provides a technical solution: a gathering and irradiation mechanism 3 is arranged at the bottom of the connecting sleeve 201, and the gathering and irradiation mechanism 3 includes a telescopic rod 301, and a connecting plate 302 is fixedly connected to the bottom of the telescopic rod 301, and a copper pressing plate 303 is fixedly connected to the bottom of the connecting plate 302. The copper pressing plate 303 is a square plate structure, and the copper pressing plate 303 is used to absorb heat.

[0020] The outer wall of the connecting plate 302 is hinged with a hinged rod 305 through a rotating shaft 304, and the other end of the hinged rod 305 is fixedly connected to a sliding rod 306. A long plate 307 is fixedly connected to one side of the connecting sleeve 201, and a hollow sliding groove 308 is provided on the inner wall of the long plate 307. The sliding rod 306 is slidably connected in the inner wall of the hollow sliding groove 308. A sliding sleeve 309 is slidably connected to the outer wall of the hinged rod 305, and a pull rope 310 is fixedly connected to one side of the sliding sleeve 309. One end of the pull rope 310 is arranged on the outside of the opening and closing plate 202, and the sliding sleeve 309 is used to slide on the outer wall of the hinged rod 305.

[0021] A scale groove 312 is provided on the top of the long plate 307 , and the outer wall of the sliding rod 306 is fixedly connected with the long plate 307 . The long plate 307 is used to pull the sliding rod 306 to reset it, and a first built-in spring is provided on the inner wall of the copper pressure plate 303 .

[0022] The sliding sleeve 309 is an annular sleeve structure, and the scale groove 312 and the sliding rod 306 are used to observe the positional relationship between them and play a role in judging the distance; When the high-precision cutting head 8 descends to cut the plate, the copper pressure plate 303 will contact the surface of the wooden board, and because the first built-in spring inside the telescopic rod 301 will always push the connecting plate 302 and the copper pressure plate 303 against the bottom wooden board, as the high-precision cutting head 8 continues to descend, the telescopic rod 301 will be pressed and contracted because the copper pressure plate 303 is pressed, and one end of the hinged rod 305 will be driven to rise vertically through the connecting plate 302 and the rotating shaft 304, so that when one end of the hinged rod 305 rises, the sliding rod 306 at the other end will begin to slide outward in the hollow sliding groove 308 in the long board 307, and the pulling spring 311 will deform, so that the hinged rod 305 is hinged and rotated on the outer wall of the connecting plate 302, and the opening and closing plate 202 is pulled by the sliding sleeve 309 and the pull rope 310, and the sliding sleeve 309 can slide on the outer wall of the hinged rod 305, so the hinged rod 305 When the pull rope 310 is pulled to the opening and closing plate 202 by the sliding sleeve 309, the sliding sleeve 309 will naturally slide on the outer wall of the hinge rod 305 and present an angle state perpendicular to the pull rope 310 and the opening and closing plate 202, so that the infrared heat radiation lamp 203 under the opening and closing plate 202 will always face the bottom end of the hinge rod 305, and the bottom end of the hinge rod 305 is the position where the high-precision cutting head 8 needs to cut and process. Therefore, as the high-precision cutting head 8 descends, the opening and closing plate 202 will continue to rotate under the hinged rotation of the rotating rod 204, and keep the infrared heat radiation lamp 203 always facing the processing position of the high-precision cutting head 8 to complete the heating work for the area, so that when the position is changed by continuous lifting and cutting, the heat radiation will not lose a lot of heat energy due to the fixed angle and the wrong irradiation position during the frequent lifting and lowering process, resulting in poor heating effect and unstable heating effect. When the heat radiation of the infrared heat radiation lamp 203 is irradiated onto the wooden board, a part of it will also be irradiated onto the connecting plate 302, and the heat will be efficiently absorbed by the connecting plate 302, so as to maintain a certain temperature of the connecting plate 302, so as to achieve that when the high-precision cutting head 8 frequently moves to cut the wooden board, the heating efficiency of the heat radiation is not enough to heat up the wooden board in the area around the high-precision cutting head 8, and the heat absorbed by the connecting plate is quickly released to the wooden board by contacting with the wooden board, so as to complete the heating effect of the wooden board with a lower temperature, and to achieve as much as possible under various working conditions, still ensure the stable heating effect of the wooden board, and then further avoid the unfavorable situation of low temperature of the wooden board; When the sliding rod 306 slides in the hollow slide groove 308, the positional relationship between the sliding rod 306 and the scale groove 312 can be observed. The farther the sliding rod 306 is from the connecting sleeve 201, the more the hinge rod 305 is pushed to hinge and rotate. This also means that the thicker the plate processed by the bottom of the high-precision cutting head 8 is, the deeper the penetration depth is. This makes it easier for the staff to quickly judge the high and low position state of the high-precision cutting head 8 at this time, as well as the approximate thickness of the plate during cutting, which is more convenient for subsequent operations and processing. Example 3: Please refer to Figure 1-13 On the basis of Embodiment 1 and Embodiment 2, the present invention provides a technical solution: an illumination adjustment mechanism 4 is provided on the outer wall of the opening and closing plate 202, and the illumination adjustment mechanism 4 includes a first sliding frame 401, and the first sliding frame 401 is slidably connected to the outer wall of the opening and closing plate 202, and a pull rod 402 is fixedly connected to one side of the first sliding frame 401, and the other end of the pull rod 402 is fixedly connected to the second sliding frame 403, and the second sliding frame 403 is slidably connected to the outer wall of the opening and closing plate 202, and a telescopic plate 404 is fixedly connected to the outer wall of the second sliding frame 403, and a fixed sleeve 405 is slidably connected to the outer wall of the telescopic plate 404.

[0023] One side of the fixing sleeve 405 is fixedly connected to the outer wall of the rotating rod 204 , and the outer wall of the fixing sleeve 405 is fixedly connected to the outer wall of the opening and closing plate 202 .

[0024] A second built-in spring is disposed on the inner wall of the fixed sleeve 405, one end of the second built-in spring is fixedly connected to one side of the telescopic plate 404, and the other side of the second built-in spring is fixedly connected to the inner wall of the fixed sleeve 405; When the connecting sleeve 201 and the high-precision cutting head 8 are lowered, and the high-precision cutting head 8 is used to cut the wooden board, the change in the angle of the hinged rod 305 will always pull the pull rope 310 to the first sliding frame 401, and the first sliding frame 401 will synchronously pull the pull rod 402, the second sliding frame 403 and the telescopic plate 404 to slide on the outer wall of the opening and closing plate 202, and the telescopic plate 404 will slide out from the fixed sleeve 405 section by section, and will pull the second built-in spring in the fixed sleeve 405 and deform it, so the sliding sleeve 309 pulls the first sliding frame 401 through the pull rope 310, so that the opening and closing plate 202 on the inner wall of the first sliding frame 401 is always pulled and drives the rotating rod 204 to rotate in an articulated manner, so as to change the angle between the opening and closing plate 202 and the infrared heat radiation lamp 203, and when the telescopic plate 404 is pulled out of the fixed sleeve 405, the infrared heat radiation lamp 203 will be covered; As the high-precision cutting head 8 descends further, the angle of rotation of the articulated rod 305 increases, and the distance that the pull rope 310 and the first sliding frame 401 slide on the opening and closing plate 202 are pulled by the sliding sleeve 309 increases, so that when the high-precision cutting head 8 descends to cut the wooden board, the surface of the infrared heat radiation lamp 203 is shielded to a certain extent by the telescopic plate 404. The more the high-precision cutting head 8 descends, the more the telescopic plate 404 shields the surface of the infrared heat radiation lamp 203. When the high-precision cutting head 8 rises away from the wooden board, the telescopic plate 404 shields the surface of the infrared heat radiation lamp 203. The less obstruction there is for the infrared heat radiation lamp 203, so as to avoid the situation where, when the high-precision cutting head 8 descends to cut the wooden board, several infrared heat radiation lamps 203 of the heat radiation mechanism 2 rotate simultaneously to heat the surface of the wooden board at the processing position, which eventually leads to excessive temperature and internal expansion of the wood, thereby affecting its cutting accuracy. When the high-precision cutting head 8 is away from the wooden board, the infrared heat radiation lamp 203 is fully opened to heat the wooden board by thermal radiation, so as to ensure sufficient heating effect at a long distance, adapt to different working conditions and take corresponding heating measures to prevent accidents.

[0025] The above are only preferred specific implementation modes of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and inventive concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
