Description

Technical Field

[0001] This invention belongs to the field of building material processing technology, and in particular relates to a fixed-length cutting device and cutting method for eaves boards. Background Technology

[0002] An eaves cladding is a decorative component along the edge of a building's roof. It refers to a wooden or decorative panel that is installed perpendicular to the ground on both sides of the roof or at the overhanging eaves. It is usually fixed to the ends of the rafters at the eaves, enclosing the rafter ends and the internal roof structure. During the production and processing of eaves cladding, the panels usually need to be cut to specified sizes. To facilitate the cutting of the panels, a cutting device is typically used.

[0003] The existing authorization announcement number CN121245267 discloses a laser cutting device for metal sheets, including a body, a power box, and a cutting head; a hollow seat is installed on the power box, and a mounting sleeve is provided on the hollow seat, which passes vertically through its interior; two rollers are provided at the lower end of the mounting sleeve, a drive wheel is fixed on the outside, and an internal thread is provided in the inner cavity; a support plate is provided above the hollow seat, and a guide mechanism is provided between the two; the support plate and the mounting sleeve are connected by an axial synchronization component, and a rotary drive mechanism is installed on the support plate; the cutting head passes vertically through the interior of the mounting sleeve, and an external thread is provided on its outer side; an angle limiting mechanism is provided between the cutting head and the hollow seat.

[0004] However, the following defects exist during use:

[0005] 1. The cutting device described above can be used for different cutting conditions through three cutting modes: flat cutting mode, curved surface cutting mode and ordinary cutting mode. However, it is not convenient to limit the cutting length of the board during use, which makes it difficult to cut the board into the specified size during the cutting process, thus making it inconvenient to use.

[0006] 2. The cutting device described above protects the rollers, cutting head, and other structures by using a protective sleeve to prevent damage to the cutting head in the event of a collision. However, during use, it is not convenient to clean the cutting area of ​​the plate, and the presence of dust and other impurities can affect the laser cutting effect on the plate.

[0007] 3. The cutting device described above adjusts the direction of the rollers and the focal length of the cutting head through a rotary drive mechanism, which improves the utilization rate of components. However, during use, it is not convenient to detect the flatness of the plate, thus affecting the laser cutting effect on the plate due to the unevenness of the plate surface.

[0018] A further feature of the present invention is that a blower is fixedly connected to the upper part of the inside of the blower housing, and a filter screen is fixedly connected to the center of the inside of the blower housing.

[0019] A further feature of the present invention is that a plurality of connecting plates are fixedly connected at equal intervals on the lower surface of the extension plate, and the vertical support arm of the connecting plate is fixedly connected to one side outer wall of the feeding rack.

[0020] A side plate is fixedly connected to the upper part of one side of the outer wall of the L-shaped frame, and a distance measuring sensor is fixedly connected to the lower surface of the side plate.

[0021] A driven gear is fixedly connected to the outer wall of the sleeve rod. The driven gear is located below the mounting plate. A second drive motor is fixedly connected to one side of the upper surface of the mounting plate. The output shaft of the second drive motor extends to the lower part of the mounting plate and is fixedly connected to a driving gear. The driving gear meshes with one side of the driven gear.

[0022] The present invention also provides a cutting method for a fixed-length cutting device for eaves boards, the cutting method specifically including the following steps:

[0023] S1: First, set the position of the baffle according to the required cutting length, start the first drive motor to drive the threaded rod to rotate, so that the first slider moves the baffle on the mounting frame in the left and right direction to the position corresponding to the predetermined length, so that the baffle serves as the limiting reference for the advance of the plate. Then, adjust the position of the L-shaped plate according to the width of the plate, move the second slider along the slide rod to make the L-shaped plate reach the corresponding position on both sides of the plate, ensuring that the first pressure plate can accurately press on the edge of the plate, and tighten the positioning bolts to fix the L-shaped plate. Then, adjust the front and back position of the second pressure plate according to the width of the plate, loosen the locking plate and move the fixing rod to make the third slider slide in the front and back direction within the fixing frame, adjust the position of the second hydraulic cylinder to align the second pressure plate with the upper surface of the plate, and then lock the locking plate.

[0024] S2: Next, material feeding begins while simultaneously performing length-direction flatness detection. The sheet material is fed in from the extension plate, and the detection component is in working condition, with the measuring wheel in contact with the sheet surface. As the sheet material is conveyed forward into the feeding rack, the measuring wheel rolls along with the sheet material. When there are uneven areas on the sheet surface along the length direction, the measuring wheel will bounce vertically, causing the measuring plate to rise and fall via the measuring rod. The distance sensor monitors the position fluctuation of the measuring plate in real time, thereby completing the detection of the sheet material's length-direction flatness.

[0025] S3: Next, when the approximate cutting position of the board material moves to below the U-shaped frame, feeding is paused, and the second drive motor is started. The second drive motor drives the drive gear to rotate, causing the sleeve rod to rotate the measuring rod to adjust the orientation of the mounting base. The direction of the measuring wheel is adjusted to be consistent with the front-back direction. Then, the second electric slide rail is started, causing the fifth slider to move the L-shaped frame in the front-back direction. The measuring wheel then rolls on the surface of the board material to detect the flatness in the width direction of the board material. After the detection is completed, the measuring wheel is reset.

[0026] S4: Then, continue feeding, conveying the sheet forward until its front end contacts the baffle. At this point, feeding stops, and the designated length of the sheet rests on the feeding rack, ready for cutting, with the cutting position located below the U-shaped frame. Activate the first hydraulic cylinder to push the first pressure plate downwards to press down on the edge of the sheet, and simultaneously activate the second hydraulic cylinder to push the second pressure plate downwards to press down on the upper surface of the sheet, firmly fixing the sheet on the feeding rack.

[0027] S5: Next, adjust the height of the cutting and cleaning components according to the thickness of the sheet material. Activate the electric push rod to lower the first electric slide rail, causing the U-shaped frame, laser cutting head, and blower housing to descend to a height corresponding to the sheet material surface. Before cutting, activate the blower assembly for cleaning. Adjust the angle of the U-shaped frame using the electric turntable so that the blower pipe at the bottom of the blower housing is above the area to be cut. The blower operates, and the airflow, filtered through the filter, is blown out from the blower pipe to clean dust and other impurities from the area to be cut on the sheet material surface. After cleaning, adjust the angle of the U-shaped frame again using the electric turntable so that the laser cutting head is above the area to be cut.

[0028] S6: Finally, the first electric slide rail is activated, driving the fourth slider to move laterally, aligning the laser cutting head with the cutting start point. The laser cutting head then performs a fixed-length cut. During the cutting process, the generated dust is removed by the accompanying dust removal structure. After the cutting is completed, the first and second hydraulic cylinders drive the first and second pressure plates to rise and reset, releasing the fixing of the sheet material. The feeding mechanism continues to transport the next section of sheet material forward, repeating the above detection, cleaning, and cutting process to achieve continuous automatic fixed-length cutting of the fascia board.

[0029] The present invention has the following beneficial effects:

[0030] 1. This invention sets up a limiting component, using a first drive motor on the mounting frame to drive the baffle to a predetermined length position as a limiting reference, and adjusts the positions of the L-shaped plate and the second pressure plate according to the width of the plate, so that the first pressure plate and the second pressure plate can firmly fix the plate to the feeding rack from the edge and the top surface, respectively, thereby achieving precise length positioning of the plate, solving the problem of inconvenience in cutting the plate to a fixed length in the prior art, and significantly improving the accuracy and consistency of the cutting dimensions.

[0031] 2. This invention, by setting up a cutting component and using an electric turntable to adjust the angle of the U-shaped frame, allows the air blower at the bottom of the blower housing to be aligned with the position of the plate to be cut. The airflow generated by the blower is filtered through a filter and then blown out from the air blower to clean the dust in the cutting area. Then, the angle is adjusted again to allow the laser cutting head to cut, thereby realizing the automatic cleaning function before cutting. This solves the problem of inconvenience in cleaning the plate cutting position in the prior art and effectively avoids the impact of dust on the laser cutting effect.

[0032] 3. This invention, by setting up a detection component, utilizes a measuring wheel to adhere to the surface of the board. During the board conveying process, a measuring rod drives the measuring plate to rise and fall, and a distance sensor monitors position fluctuations in real time. Simultaneously, a second drive motor adjusts the direction of the measuring wheel and, in conjunction with the movement of a second electric slide rail, performs flatness detection in both the length and width directions of the board. This achieves comprehensive flatness detection of the board before cutting, solving the problem in existing technologies where it is inconvenient to detect the flatness of the board before cutting, and avoiding cutting defects caused by uneven board surfaces.

[0062] S1: First, set the position of the baffle 202 according to the required cutting length, start the first drive motor 201a to drive the threaded rod 201b to rotate, so that the first slider 201c drives the baffle 202 to move in the left and right direction on the mounting frame 201 to the position corresponding to the predetermined length, so that the baffle 202 serves as the limiting reference for the advance of the plate. Then, adjust the position of the L-shaped plate 203 according to the width of the plate, move the second slider 202b along the slide rod 202a so that the L-shaped plate 203 reaches the corresponding position on both sides of the plate, ensuring that the first pressure plate 204 can accurately press on the edge of the plate, and tighten the positioning bolt 202c to fix the L-shaped plate 203. Then, adjust the front and back position of the second pressure plate 206 according to the width of the plate, loosen the locking plate 205c and move the fixing rod 205b so that the third slider 205a slides in the front and back direction in the fixing frame 205, adjust the position of the second hydraulic cylinder 206a so that the second pressure plate 206 is aligned with the upper surface of the plate, and then lock the locking plate 205c.

[0063] S2: Next, material feeding begins while simultaneously performing length-direction flatness detection. The sheet material is fed in from the extension plate 401. At this time, the detection component 4 is in working condition, and the measuring wheel 407 is in contact with the sheet material surface. As the sheet material is conveyed forward into the feeding rack 1, the measuring wheel 407 rolls along with the sheet material. When there are uneven areas on the sheet material surface along the length direction, the measuring wheel 407 will generate vertical jumps, which will drive the measuring plate 406a to rise and fall through the measuring rod 406. The distance sensor 404b monitors the position fluctuation of the measuring plate 406a in real time, thereby completing the detection of the length-direction flatness of the sheet material.

[0064] S3: Next, when the approximate cutting position of the board material moves below the U-shaped frame 402, feeding is paused, and the second drive motor 405c is started. The second drive motor 405c drives the driving gear 405d to rotate, which in turn drives the driven gear 405b to rotate, causing the sleeve rod 405a to rotate the measuring rod 406 to adjust the orientation of the mounting base 406b. The direction of the measuring wheel 407 is adjusted to be consistent with the front-back direction. Then, the second electric slide rail 403 is started, causing the fifth slider 403a to move the L-shaped frame 404 in the front-back direction. The measuring wheel 407 then rolls on the surface of the board material to detect the flatness in the width direction of the board material. After the detection is completed, the measuring wheel 407 is reset.

[0065] S4: Then, continue feeding, conveying the sheet forward until its front end contacts the baffle 202. At this point, feeding stops, and the designated length of the sheet stops precisely on the feeding rack 1 to be cut, with the cutting position located below the U-shaped frame 304. Activate the first hydraulic cylinder 204a to push the first pressure plate 204 downward to press down on the edge of the sheet, and simultaneously activate the second hydraulic cylinder 206a to push the second pressure plate 206 downward to press down on the upper surface of the sheet, firmly fixing the sheet on the feeding rack 1.

[0066] S5: Next, adjust the height of the cutting and cleaning components according to the thickness of the sheet material. Activate the electric push rod 303a to lower the first electric slide rail 303, causing the U-shaped frame 304, the laser cutting head 305, and the blower housing 306 to descend to a height corresponding to the surface of the sheet material. Before cutting, activate the blower assembly for cleaning. Adjust the angle of the U-shaped frame 304 using the electric turntable 304a so that the blower pipe 307 at the bottom of the blower housing 306 is above the position to be cut. The blower 306a operates, and the airflow, filtered by the filter screen 306b, is blown out from the blower pipe 307 to clean dust and other impurities from the area to be cut on the sheet material surface. After cleaning, adjust the angle of the U-shaped frame 304 again using the electric turntable 304a so that the laser cutting head 305 is above the position to be cut.

[0067] S6: Finally, the first electric slide rail 303 is activated, driving the fourth slider 303d to move laterally, aligning the laser cutting head 305 with the cutting starting point. The laser cutting head 305 is then activated to perform a fixed-length cut. During the cutting process, the generated dust is removed by the matching dust removal structure. After the cutting is completed, the first hydraulic cylinder 204a and the second hydraulic cylinder 206a drive the first pressure plate 204 and the second pressure plate 206 to rise and reset, releasing the fixation on the board. The feeding mechanism continues to convey the next section of board forward, repeating the above detection, cleaning, and cutting process to achieve continuous automatic fixed-length cutting of the eaves board.

[0068] The above are merely preferred embodiments of the present invention and do not limit the present invention. Any modifications, equivalent substitutions, or improvements made to the technical solutions described in the foregoing embodiments, or to some of the technical features, shall fall within the protection scope of the present invention.

A cutting method for a fixed-length cutting device for eaves boards as described in any one of claims 1-9, characterized in that, The cutting method specifically includes the following steps: S1: First, set the position of the baffle (202) according to the required cutting length, start the first drive motor (201a) to drive the threaded rod (201b) to rotate, so that the first slider (201c) drives the baffle (202) to move in the left and right direction on the mounting frame (201) to the position corresponding to the predetermined length, so that the baffle (202) serves as the limiting reference for the advance of the plate. Then, adjust the position of the L-shaped plate (203) according to the width of the plate, move the second slider (202b) along the slide rod (202a) so that the L-shaped plate (203) reaches the corresponding position on both sides of the plate, ensuring that the first pressure plate (204) can accurately press on the edge of the plate, and tighten the positioning bolt (202c) to fix the L-shaped plate (203). Adjust the front and rear positions of the second pressure plate (206) according to the width of the plate, loosen the locking disc (205c), move the fixing rod (205b) to make the third slider (205a) slide in the front and rear direction within the fixing frame (205), adjust the position of the second hydraulic cylinder (206a) so that the second pressure plate (206) is aligned with the upper surface of the plate, and then lock the locking disc (205c). S2: Next, the material is fed in and the flatness of the length direction is detected simultaneously. The board is fed in from the extension plate (401). At this time, the detection component (4) is in working state and the measuring wheel (407) is in contact with the surface of the board. During the process of the board being conveyed forward into the feeding rack (1), the measuring wheel (407) rolls with the movement of the board. When there is an uneven area on the surface of the board along the length direction, the measuring wheel (407) will jump vertically and drive the measuring plate (406a) to rise and fall through the measuring rod (406). The distance sensor (404b) monitors the position fluctuation of the measuring plate (406a) in real time, thereby completing the detection of the flatness of the board in the length direction. S3: Immediately afterwards, when the approximate cutting position of the board moves to below the U-shaped frame (402), the feeding is paused, and the second drive motor (405c) is started. The second drive motor (405c) drives the active gear (405d) to drive the driven gear (405b) to rotate, causing the sleeve rod (405a) to drive the measuring rod (406) to rotate to adjust the orientation of the mounting base (406b), and adjust the direction of the measuring wheel (407) to be consistent with the front and back direction. Then, the second electric slide rail (403) is started to cause the fifth slider (403a) to drive the L-shaped frame (404) to move in the front and back direction. The measuring wheel (407) then rolls on the surface of the board to detect the flatness of the board in the width direction. After the detection is completed, the measuring wheel (407) is reset. S4: Then, continue feeding, conveying the plate forward until its front end contacts the baffle (202). At this point, feeding stops, and the specified length of the plate just stops on the feeding rack (1) to be cut, with the cutting position located below the U-shaped frame (304). Start the first hydraulic cylinder (204a) to push the first pressure plate (204) downward to press down on the edge of the plate, and at the same time start the second hydraulic cylinder (206a) to push the second pressure plate (206) downward to press down on the upper surface of the plate, firmly fixing the plate on the feeding rack (1); S5: Next, adjust the height of the cutting and cleaning components according to the thickness of the sheet material. Start the electric push rod (303a) to push the first electric slide rail (303) down, so that the U-shaped frame (304) and the laser cutting head (305) and blower shell (306) on it are lowered to the height corresponding to the surface of the sheet material. Before cutting, start the blower assembly for cleaning. Adjust the angle of the U-shaped frame (304) by the electric turntable (304a) so that the blower pipe (307) at the bottom of the blower shell (306) is above the position to be cut. The blower (306a) works, and the airflow is filtered through the filter screen (306b) and blown out from the blower pipe (307) to clean the dust and other impurities in the area to be cut on the surface of the sheet material. After cleaning, adjust the angle of the U-shaped frame (304) again by the electric turntable (304a) so that the laser cutting head (305) is above the position to be cut. S6: Finally, the first electric slide rail (303) is activated, driving the fourth slider (303d) to move laterally, aligning the laser cutting head (305) with the cutting starting point. The laser cutting head (305) is then activated to perform a fixed-length cut. During the cutting process, the generated smoke and dust are removed by the matching dust removal structure. After the cutting is completed, the first hydraulic cylinder (204a) and the second hydraulic cylinder (206a) drive the first pressure plate (204) and the second pressure plate (206) to rise and reset, releasing the fixation of the board. The feeding mechanism continues to convey the next section of board forward, repeating the above detection, cleaning and cutting process to achieve continuous automatic fixed-length cutting of the eaves board.
