Description

Technical Field

[0001] This invention relates to the field of bamboo and wood fiber integrated wall panel production and processing technology, and more specifically, to a dust-free cutting mechanism for the production of bamboo and wood fiber integrated wall panels. Background Technology

[0002] Bamboo and wood fiber integrated wall panels are environmentally friendly wall panels made from bamboo and wood powder, calcium powder, PVC, and other raw materials through extrusion molding. They are widely used in interior wall decoration. During the wall panel production process, a cutting machine is required to cut the panels to a fixed length.

[0003] Existing cutting machines are equipped with a sealing cover that covers the cutting blade. The sealing cover is pressed against the plate and moves with the cutting action, relying on negative pressure to suck up the cutting dust.

[0004] In existing technology, the bottom of the sealing cover slides directly in contact with the board. When moving, the rigid cover can easily scratch the surface of the bamboo and wood fiber wall panel. Adding a brush to the bottom of the sealing cover can reduce the risk of scratches, but the gaps in the brush are very easy to stick to and accumulate cutting dust. The dust can easily fall onto the board, resulting in incomplete dust removal and affecting the dust removal effect. After long-term use, the brush hardens and the seal fails, causing dust to overflow. At the same time, the hardened brush bristles can still scratch the board surface. Summary of the Invention

[0005] To address the above deficiencies, this invention provides a dust-free cutting mechanism for the production of bamboo and wood fiber integrated wall panels, thus solving the aforementioned problems.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A dust-free cutting mechanism for the production of bamboo and wood fiber integrated wall panels includes: The sealing cover body; The cutting saw blade is housed inside the sealed cover body, and the side wall of the sealed cover body is provided with a dust removal and air intake. Vertical openings are located on the front and rear sides of the sealing cover body; A transmission mechanism, located on the sealing cover body, is used to drive the cutting saw blade to lift and rotate to cut the wall panel. The transmission mechanism is linked to a sealing component for sealing the vertical opening. A flexible sealing mechanism is located inside the sealing cover body. The flexible sealing mechanism includes two rotating rollers, which are rotatably connected to the lower sides of the sealing cover body, and a sealing strip is sleeved between the two rotating rollers. The lower side of the sealing strip protrudes from the outer side of the bottom of the sealing cover body and is used to press against the surface of the wall panel. When the sealing cover body moves and cuts relative to the wall panel, the rotating roller drives the sealing strip to rotate cyclically.

[0007] Furthermore, the transmission mechanism includes a fixed frame fixedly installed on the top of the sealing cover body. The sealing cover body is provided with a sealing frame. The side wall of the sealing frame slides with the front and rear outer walls of the sealing cover body. The side wall of the sealing frame seals the top of the vertical opening. A linear drive element is installed on the fixed frame. The output end of the linear drive element passes through the fixed frame and is fixedly connected to the top of the sealing frame. A bearing seat is installed on the side wall of the sealing frame. An output shaft is connected between the two bearing seats. The cutting saw blade is connected to the output shaft. One end of the output shaft extends through the sealing frame. A driven wheel is connected to the end of the output shaft extending out of the sealing frame. A rotary drive element is installed on the sealing frame. A drive wheel is connected to the output end of the rotary drive element. A transmission belt connects the drive wheel and the driven wheel.

[0008] Furthermore, the sealing assembly includes a sealing gasket and a bellows cover. The sealing gasket is disposed on the sliding contact surface between the sealing frame and the sealing cover body. The bellows cover is disposed on the front and rear sides of the sealing cover body and below the vertical opening. The bottom end of the bellows cover is fixedly connected to the sealing cover body, and the top end of the bellows cover is fixedly connected to the bottom of the side wall of the sealing frame.

[0009] The sealing frame causes the bellows protective cover to extend and retract accordingly, and together with the sealing gasket, it seals the vertical opening. The vertical opening is blocked at different heights of the saw blade's rise and fall to prevent dust from escaping from the opening.

[0010] Furthermore, the two ends of the rotating roller are provided with toothed grooves, the sealing belt is a synchronous belt, the synchronous belt is assembled between the two rotating rollers, and the synchronous belt meshes with the toothed grooves for transmission.

[0011] The use of a synchronous belt in conjunction with a toothed groove prevents the sealing belt from slipping during rotation, thus improving the sealing effect.

[0012] Furthermore, the flexible sealing mechanism also includes a sealing plate and a brush roller. The sealing plate is fixedly connected to the left inner wall of the sealing cover body. The end of the sealing plate away from the sealing cover body is in contact with the left rotating roller. The brush roller is rotatably connected to the right inner wall of the sealing cover body. The bristles on the brush roller are in contact with the right rotating roller. Sealing brushes are connected to the front and rear side walls of the sealing cover body. The bristles of the sealing brushes cooperate with the side of the sealing strip for sealing.

[0013] Furthermore, the bristles of the brush roller and the sealing brush are made of flexible and wear-resistant material, and the sealing plate is made of flexible silicone material.

[0014] It ensures a tight seal without damaging the sealing strip, thus extending its service life.

[0015] Furthermore, an inclined fixing plate is fixedly connected inside the sealing cover body. The inclined fixing plate is located on the right side of the rotating roller and inside the sealing strip. A cleaning brush is connected to the inclined fixing plate, and the bristles of the cleaning brush are in contact with both the rotating roller and the sealing strip.

[0016] Dust is removed from the inside of the sealing strip by cleaning the brush, preventing dust from entering the toothed groove and causing jamming, thus maintaining stable long-term circulation.

[0017] Furthermore, the dust extraction air inlet is connected to an external dust extraction device via a flexible pipe.

[0018] The beneficial effects of this invention are: The flexible sealing mechanism is adopted. The lower side of the sealing strip protrudes from the bottom of the sealing cover body and presses against the wall panel surface. When the sealing cover body moves relative to the wall panel for cutting, the rotating roller drives the sealing strip to rotate in a cycle, forming a continuous seal as it moves with the cutting, so that the cutting cavity is always in a closed state. In conjunction with the dust removal air intake, the cutting dust is concentrated and removed, suppressing dust emission from the source. The rotating roller, sealing strip and wall panel are in rolling contact with each other without relative sliding, so as not to scratch the film surface of the wall panel.

[0019] The sealing strip is flexibly sealed around its perimeter by a sealing plate, brush roller, and sealing brush, preventing dust from escaping from the gap between the sealing strip and the sealing cover body, thus improving the sealing effect and ensuring thorough dust removal. As the sealing strip rotates, it passes through the sealing plate and brush roller, which cleans the dust adhering to the surface of the sealing strip and the rotating roller, keeping the sealing strip clean and preventing dust from falling onto the wall panel, thereby improving the dust removal effect.

[0021] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention can be practiced in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0022] This application provides a dust-free cutting mechanism for the production of bamboo and wood fiber integrated wall panels. Please refer to [link / reference]. Figures 1-8 :include: Sealing cover body 1; The cutting saw blade 2 is located inside the sealing cover body 1, and the side wall of the sealing cover body 1 is provided with a dust removal and air intake 3. Vertical openings 4 are located on the front and rear sides of the sealing cover body 1; The transmission mechanism, located on the sealing cover body 1, is used to drive the cutting saw blade 2 to lift and rotate to cut the wall panel. The transmission mechanism is linked to a sealing component for sealing the vertical opening 4. A flexible sealing mechanism is located inside the sealing cover body 1. The flexible sealing mechanism includes two rotating rollers 5, which are rotatably connected to the lower sides of the sealing cover body 1 respectively. A sealing strip 6 is sleeved between the two rotating rollers 5. The lower side of the sealing strip 6 protrudes from the bottom outer side of the sealing cover body 1 and is used to press against the surface of the wall panel. When the sealing cover body 1 moves and cuts relative to the wall panel, the rotating roller 5 drives the sealing strip 6 to rotate cyclically.

[0023] In practical applications, the sealing cover body 1 is installed on the cutting carriage of the cutting equipment. The cutting carriage of the cutting equipment drives the sealing cover body 1 to move laterally relative to the wall panel. The wall panel is continuously conveyed, and the cutting saw blade 2 is located above the position of the wall panel that needs to be cut. During cutting, the lower side of the sealing strip 6 presses against the wall panel surface. The transmission mechanism drives the cutting saw blade 2 to rise, fall, and rotate to cut the wall panel. When the sealing cover body 1 moves laterally, the lower side of the sealing strip 6 adheres to the wall panel surface. Since the wall panel is stationary while the sealing cover body 1 moves, the sealing strip 6 rubs against the wall panel surface, causing the rotating roller 5 and the sealing strip 6 to rotate cyclically. The sealing strip 6 continuously changes the strip segment in contact with the wall panel as the sealing cover body 1 moves, always sealing the gap between the bottom of the sealing cover body 1 and the wall panel, forming a continuous seal as the cutting moves. The dust extraction port 3 draws in the dust and wood chips generated during cutting inside the sealing cover body 1 and discharges them through the extraction port 3. After the cutting is completed, the cutting saw blade 2 is lifted and reset. The rotating roller 5, the sealing strip 6, and the wall panel are in rolling contact without relative sliding, so as not to scratch the film surface of the wall panel.

[0024] Refer to the instruction manual appendix Figure 1 Instruction manual attached Figure 2 Included with instruction manual Figure 4 The transmission mechanism includes a fixed frame 7 fixedly installed on the top of the sealing cover body 1. A sealing frame 8 is provided on the sealing cover body 1. The side wall of the sealing frame 8 slides with the front and rear outer walls of the sealing cover body 1. The side wall of the sealing frame 8 seals the top of the vertical opening 4. A linear drive element 9 is installed on the fixed frame 7. The output end of the linear drive element 9 passes through the fixed frame 7 and is fixedly connected to the top of the sealing frame 8. A bearing seat 10 is installed on the side wall of the sealing frame 8. An output shaft 11 is connected between the two bearing seats 10. The cutting saw blade 2 is connected to the output shaft 11. One end of the output shaft 11 extends through the sealing frame 8. A driven wheel 12 is connected to the end of the output shaft 11 extending out of the sealing frame 8. A rotary drive element 13 is installed on the sealing frame 8. A drive wheel 14 is connected to the output end of the rotary drive element 13. A transmission belt 15 is connected between the drive wheel 14 and the driven wheel 12.

[0025] In practical applications, during cutting, the rotary drive element 13 starts working, and the output end of the rotary drive element 13 drives the drive wheel 14 to rotate. The drive wheel 14 drives the driven wheel 12 and the output shaft 11 to rotate through the transmission belt 15. The output shaft 11 drives the cutting saw blade 2 to rotate at high speed. The linear drive element 9 starts working, and the output end of the linear drive element 9 extends into and drives the sealing frame 8 to slide downward along the front and rear outer walls of the sealing cover body 1, driving the cutting saw blade 2 to descend synchronously, cut into the wall panel surface and perform cutting. After cutting is completed, the linear drive element 9 drives the sealing frame 8 to rise, and the cutting saw blade 2 is lifted away from the wall panel and reset. The lifting and rotation of the cutting saw blade 2 can be controlled independently, and the cutting depth can be flexibly adjusted according to the wall panel thickness.

[0026] Refer to the instruction manual appendix Figure 4 Included with instruction manual Figure 5The sealing assembly includes a sealing gasket 16 and a bellows cover 17. The sealing gasket 16 is disposed on the sliding contact surface between the sealing frame 8 and the sealing cover body 1. The bellows cover 17 is disposed on the front and rear sides of the sealing cover body 1. The bellows cover 17 is disposed below the vertical opening 4. The bottom end of the bellows cover 17 is fixedly connected to the sealing cover body 1, and the top end of the bellows cover 17 is fixedly connected to the bottom of the side wall of the sealing frame 8.

[0027] In practical applications, when the sealing frame 8 is raised or lowered, the sealing frame 8 drives the bellows protective cover 17 to extend and retract accordingly, and works with the sealing gasket 16 to seal the vertical opening 4. The vertical opening 4 is blocked at different heights of the saw blade's rise and fall to prevent dust from escaping from the opening.

[0028] Refer to the instruction manual appendix Figure 3 Included with instruction manual Figure 7 The two ends of the rotating roller 5 are provided with toothed grooves 18, and the sealing belt 6 is a synchronous belt. The synchronous belt is assembled between the two rotating rollers 5 and meshes with the toothed grooves 18 for transmission.

[0029] In practical applications, a synchronous belt is used in conjunction with the toothed groove 18 to prevent the sealing belt 6 from slipping when rotating, thereby improving the sealing effect.

[0030] Refer to the instruction manual appendix Figure 2 Instruction manual attached Figure 3 Instruction manual attached Figure 6 Included with instruction manual Figure 8 The flexible sealing mechanism also includes a sealing plate 19 and a brush roller 20. The sealing plate 19 is fixedly connected to the left inner wall of the sealing cover body 1. The end of the sealing plate 19 away from the sealing cover body 1 is in contact with the left rotating roller 5. The brush roller 20 is rotatably connected to the right inner wall of the sealing cover body 1. The bristles on the brush roller 20 are in contact with the right rotating roller 5. The front and rear side walls of the sealing cover body 1 are connected to sealing brushes 21. The bristles of the sealing brushes 21 cooperate with the side of the sealing strip 6 for sealing. The bristles of the brush roller 20 and the sealing brushes 21 are made of flexible wear-resistant material. The sealing plate 19 is made of flexible silicone material.

[0031] In practical applications, the left side of the sealing strip 6 is sealed by the sealing plate 19, the right side of the sealing strip 6 is sealed by the brush roller 20, and the front and rear of the sealing strip 6 are sealed by the sealing brush 21. This prevents dust from escaping from the gap between the sealing strip 6 and the sealing cover body 1, improving the sealing effect, ensuring a tight seal, and preventing damage to the sealing strip 6, thus extending its service life. The brush roller 20 and the sealing brush 21 are located inside the sealing cover body 1 and do not directly contact the wall panel surface, preventing the problem of dust accumulation and hardening on the brush that could scratch the panel. During the cyclical rotation of the sealing strip 6, as it passes through the sealing plate 19 and the brush roller 20, the dust adhering to the surface of the sealing strip 6 and the rotating roller 5 can be cleaned, keeping the sealing strip 6 clean and preventing dust from falling onto the wall panel, thereby improving the dust removal effect.

[0032] Refer to the instruction manual appendix Figure 2 Instruction manual attached Figure 3 Included with instruction manual Figure 8 An inclined fixing plate 22 is fixedly connected inside the sealing cover body 1. The inclined fixing plate 22 is located on the right side of the rotating roller 5 and inside the sealing strip 6. A cleaning brush 23 is connected to the inclined fixing plate 22. The bristles of the cleaning brush 23 are in contact with the rotating roller 5 and the sealing strip 6 at the same time.

[0033] In practical applications, during the cyclic rotation of the sealing strip 6, when it passes the cleaning brush 23, the brush bristles scrape off the dust inside the sealing strip 6, keeping the sealing strip 6 clean and preventing dust from entering the toothed groove 18 and causing jamming. This ensures stable long-term cyclic operation.

[0034] Refer to the instruction manual appendix Figure 2 Included with instruction manual Figure 3 The dust extraction air inlet 3 is connected to an external dust extraction device via a flexible pipe 24.

[0035] In practical applications, during operation, an external dust collection device is used to extract the dust and wood chips generated during cutting inside the sealed cover body 1, which are then discharged through the air intake 3 and the flexible pipe 24.
