[0025] Example:

[0026] like Figures 1 to 4As shown, this utility model embodiment provides a special equipment for cutting sector-shaped plates, including a frame 1, a cutting unit 2, a conveying unit 3, a protective cover 4, a housing 5, and a chamfer ruler 6.

A fixing plate 205 is installed on the crossbar 204. Several movable rods 206 are movably installed on the fixing plate 205. An adjusting plate 207 is fixedly installed on the top of the movable rods 206. A screw 208 is installed in the middle of the adjusting plate 207. The screw 208 passes through the adjusting plate 207 and the fixing plate 205. An adjusting turntable 209 is installed at the top of the screw 208. A telescopic rod 210 is connected to the bottom of the movable rod 206. A spring 211 is installed between the telescopic rod 210 and the movable rod 206. An mounting plate 212 is installed at the bottom of the telescopic rod 210 that is adjacent to and parallel to the saw blade 203. Several short pressure rollers 213 are fixedly installed on the mounting plate 212.

[0027] This embodiment of the invention comprises a frame 1, a cutting unit 2, a conveying unit 3, a protective cover 4, a housing 5, and a chamfer ruler 6 as the main body of the equipment. The cutting unit 2 is fixed to the top of the frame 1 by two vertical rods 201. A motor 202 is mounted on the vertical rods 201, and the shaft of the motor 202 is connected to a saw blade 203 to achieve the cutting function. The top of the vertical rods 201 is fixed by a horizontal rod 204, and a fixing plate 205 is mounted on the horizontal rod 204. Several movable rods 206 are movably connected to the fixing plate 205. The top of the movable rods 206 is fixed to an adjusting plate 207. A screw 208 passes through the middle of the adjusting plate 207 and the fixing plate 205. An adjusting turntable 209 is provided at the top of the screw 208. Rotating the adjusting turntable 209 can move the movable rods 206 up and down. The movable rod 206 is connected to the telescopic rod 210 at its bottom. A spring 211 is installed between the telescopic rod 210 and the movable rod 206 to provide elastic pressure. An installation plate 212 is installed at the bottom of the telescopic rod 210 adjacent to and parallel to the saw blade 203. Several short pressure rollers 213 are fixed on the installation plate 212. The short pressure rollers 213 are connected to the movable rod 206 through the spring 211 and the telescopic rod 210. They can automatically press the board during cutting to prevent the board from shifting due to vibration or uneven force, ensuring cutting accuracy and reducing safety hazards caused by board slippage. Each unit is independently installed on the frame 1, with a compact structure and easy maintenance. The protective cover 4 covers the cutting unit 2 to block the flying debris when the saw blade 203 is working, improving the safety of the operator.

[0028] In one feasible implementation scheme, such as Figure 1 and Figure 2 As shown, the conveying unit 3 includes an active roller 301 and a passive roller 302. The active roller 301 and the passive roller 302 are installed at both ends of the upper part of the frame 1. The active roller 301 and the passive roller 302 are connected by a conveyor belt 303. The input end of the conveyor belt 303 is at one end of the active roller 301, and the output end of the conveyor belt 303 is at one end of the passive roller 302. The active roller 301 is connected to a motor 305 via a belt 304. The motor 305 is installed at the bottom of the frame 1. By installing the active roller 301 and the passive roller 302 at the upper ends of the frame 1 respectively, and connecting them via a conveyor belt 303, the input end of the conveyor belt 303 is located on one side of the active roller 301 and the output end is located on the other side of the passive roller 302. The active roller 301 is connected to the motor 305 installed at the bottom of the frame 1 via a belt 304. The motor 305 drives the active roller 301 to rotate, which in turn drives the conveyor belt 303 to transport the board. This reduces the manual pushing of the board, lowers labor intensity, and improves production efficiency. The active roller 301 and the passive roller 302 work together to ensure the smooth operation of the conveyor belt 303, preventing the board from shifting or getting stuck during transport. This provides a stable processing benchmark for subsequent cutting processes. The input and output directions of the conveyor belt 303 are clear and can be precisely matched with the position of the cutting unit 2, ensuring that the board passes through the saw blade 203 along a preset path, thus improving the continuity of the cutting process.

[0029] In one feasible implementation scheme, such as Figures 1 to 3 As shown, a slide rail 401 is provided on the side of the protective cover 4 near the input end of the conveyor belt 303, and an infrared emitter 402 is slidably mounted on the slide rail 401. By horizontally setting the slide rail 401 on the side of the protective cover 4 near the input end of the conveyor belt 303, and slidably mounting the infrared emitter 402 on the slide rail 401, the operator can adjust the position of the infrared emitter 402 on the slide rail 401 according to the cutting requirements, so that the emitted infrared rays are aligned with the cutting marking lines on the board. The infrared emitter 402 provides a visual cutting baseline, replacing the traditional visual alignment method, avoiding cutting angle or size deviations caused by human judgment errors. It is especially suitable for high-precision processing scenarios, and can also adapt to the cutting requirements of different specifications of boards, improving the applicability and ease of operation of the equipment. At the same time, it reduces the frequency of manual approach to the cutting area, reduces operational risks, improves alignment efficiency, and shortens the preparation time for a single cutting.

[0030] In one feasible implementation scheme, such as Figure 3As shown, a control button 403 is provided on the front of the protective cover 4. By providing the control button 403 on the front of the protective cover 4, the button is electrically connected to the first motor 202, the second motor 305, and the infrared transmitter 402 through a circuit. This allows for start / stop control or parameter adjustment of the components of the first motor 202, the second motor 305, and the infrared transmitter 402. At the same time, operators can perform operations such as starting, stopping, and adjusting the speed of the equipment from a safe distance, avoiding direct contact with the high-speed rotating saw blade 203, improving operational safety, facilitating rapid response to operational needs, reducing production interruptions caused by cumbersome operating procedures, and improving equipment operating efficiency.

[0031] In one feasible implementation scheme, such as Figure 1 and Figure 2 As shown, the chamfering ruler 6 includes a cantilever rod 601, which is vertically mounted on the outer casing 5 on one side of the input end. A connecting rod 602 is provided at the free end of the cantilever rod 601, and a ruler rod 603 is rotatably connected to the connecting rod 602. By assembling the cantilever rod 601, connecting rod 602, and ruler rod 603 into the chamfering ruler 6, the cantilever rod 601 is vertically mounted on the outer casing 5, and its free end is rotatably connected to the ruler rod 603 via the connecting rod 602. The ruler rod 603 can rotate around the connecting rod 602 to adjust the angle, forming cutting reference edges at different angles. This replaces the traditional estimation method without dedicated tools, solving the problem of existing equipment's inability to guarantee angle accuracy. It meets the needs of high-precision scenarios such as furniture manufacturing and decoration. Precise angle control can reduce the scrap rate of boards caused by cutting errors, save raw materials such as wood, and reduce enterprise production costs.

[0032] In one feasible implementation scheme, such as Figure 1 As shown, a power distribution box 101 is installed on the frame 1. The power distribution box 101 is electrically connected to motor 202, motor 305, infrared transmitter 402, and control button 403. By installing the power distribution box 101 on the frame 1, and electrically connecting it to motor 202, motor 305, infrared transmitter 402, and control button 403 via wires, the power supply and signal transmission to each electrical component are realized, forming a complete control system. As the control core of the equipment, the power distribution box 101 can centrally distribute power, regulate voltage, and control the coordinated operation of each component through circuit logic, avoiding action conflicts caused by independent control. The circuit is integrated into the power distribution box 101, reducing external line exposure and lowering the risk of electrical faults such as leakage and short circuits. At the same time, it facilitates regular maintenance and repair, ensuring long-term stable operation of the equipment. In addition, it can be expanded to connect other auxiliary equipment according to production needs, improving the intelligence and automation level of the equipment.

[0033] In one feasible implementation scheme, such as Figure 1 and Figure 2As shown, several long pressure rollers 102 are installed on the top of the frame 1. The long pressure rollers 102 are installed inside the protective cover 4 and are perpendicular to the conveyor belt 303. By installing several long pressure rollers 102 on the top of the frame 1, the long pressure rollers 102 are located inside the protective cover 4, and their axes are perpendicular to the conveying direction of the board. During the cutting process, the long pressure rollers 102 press the surface of the board at a preset height, forming a double fixation with the short pressure rollers 213 of the cutting unit 2. The long pressure rollers 102 cover a large area of ​​the board. In conjunction with the short pressure rollers 213, the board can be effectively suppressed from jumping up and down or shifting laterally during the conveying and cutting process. This is especially suitable for thinner or easily deformable fan-shaped boards. Stable board fixation can reduce the risk of wear or breakage of the saw blade 203 due to uneven force, extend the service life of the saw blade 203, and reduce the cost of consumable replacement.

[0034] In one feasible implementation scheme, such as Figure 1 and Figure 3 As shown, a filter table 7 is installed at the output end of the conveying unit 3. A grid 701 parallel to the output direction is provided on the upper part of the filter table 7, and an inclined plate 702 is provided on the lower part of the grid 701. The top of the filter table 7 is inclined. By installing a filter table 7 at the output end of the conveying unit 3, the top of the filter table 7 is inclined, and the upper part is equipped with a grid 701 parallel to the output direction. Below the grid 701 is an inclined plate 702. The cut board is conveyed to the filter table 7 via the conveyor belt 303. The grid 701 can block the board, and the debris falls through the gaps in the grid 701 and slides down the inclined plate 702 to the collection area. The inclined top and the inclined plate 702 are designed to use gravity to accelerate the sliding of debris, avoiding the accumulation of debris on the conveyor belt 303 or the cutting area, keeping the working environment clean. The debris falls to the bottom of the inclined plate 702 and can be uniformly treated by an external receiving box or a vacuum cleaner, reducing the frequency of manual cleaning, improving production continuity, and preventing debris from entering the subsequent processing stage with the board, preventing debris from scratching the surface of the board or affecting the operation of other equipment, ensuring product quality and equipment safety.

[0035] In one feasible implementation scheme, such as Figures 1 to 4 As shown, the frame 1 is provided with support legs 103 at its bottom. By providing support legs 103 at the bottom of the frame 1, the height of the support legs 103 can be adjusted to keep the equipment level, adapting to ground with different flatness. The support legs 103 provide reliable support, preventing the frame 1 from tilting due to uneven ground, ensuring the relative positional accuracy of components such as the cutting unit 2 and the conveying unit 3, preventing cutting errors or mechanical failures caused by equipment shaking, and reducing fatigue wear of the frame 1 and internal components due to vibration or uneven stress, thereby increasing the overall service life of the equipment and reducing maintenance costs.

[0036] In this embodiment of the utility model, a special equipment for cutting fan-shaped plates is implemented by placing the frame 1 on a flat ground and installing bottom support legs 103. The height of the support legs 103 is adjusted to keep the frame 1 horizontal, ensuring the stability of the equipment and preventing shaking during cutting that could affect accuracy. Two vertical rods 201 are fixed to the top of the frame 1, ensuring that the vertical rods 201 are perpendicular to the surface of the frame 1. A motor 202 is installed in the middle of the vertical rods 201, and a saw blade 203 is fixed to the shaft of the motor 202. The installation firmness and rotation smoothness of the saw blade 203 are checked. A horizontal rod 204 is installed at the top of the vertical rods 201 and fixed with bolts to form a stable structure. A fixing plate 205 is installed on the horizontal rod 204, and several movable rods 206 are passed through the fixing plate 205. An adjusting plate 207 is connected to the top, and a screw 208 passes through the middle and an adjusting turntable 209 is installed, ensuring that the movable rods 206 can move up and down synchronously when the turntable is rotated. A telescopic rod 210 is connected to the bottom of the movable rods 206 for telescopic movement. A spring 211 is installed between the rod 210 and the movable rod 206. The preload of the spring 211 is adjusted to a suitable level. An installation plate 212 is installed at the bottom of the telescopic rod 210, which is adjacent to and parallel to the saw blade 203. A short pressure roller 213 is fixed on the installation plate 212. The rotation direction of the short pressure roller 213 is parallel to that of the saw blade 203. An active roller 301 and a passive roller 302 are installed at both ends of the upper part of the frame 1, ensuring that their axes are parallel and perpendicular to the frame 1. The conveyor belt 303 is fitted over the active roller 301 and the passive roller 302. The tension of the conveyor belt 303 is adjusted. A second motor 305 is installed at the bottom of the frame 1. The second motor 305 is connected to the active roller 301 via a belt 304. Ensure the belt 304 is properly tensioned, confirm the input and output directions of the conveyor belt 303 are correct and aligned with the cutting unit 2, then wrap the protective cover 4 around the cutting unit 2 and secure it to the top of the frame 1 with bolts, ensuring the protective cover 4 completely covers the saw blade 203 and transmission components. Install a horizontal slide rail 401 on the side of the protective cover 4 closest to the input end of the conveyor belt 303, and slide an infrared transmitter 402 on the slide rail 401. Adjust the transmitter's position so it can move laterally along the slide rail 401. Install a control button 403 on the front of the protective cover 4, ensuring the button is positioned for easy operation from a safe distance. Wrap the outer casing 5 around the frame 1 to form a complete protective structure for the equipment. The structure includes a cantilever rod 601 vertically installed on one side of the input end of the outer casing 5. A ruler rod 603 is rotatably connected to the free end of the cantilever rod 601 via a connecting rod 602, ensuring that the ruler rod 603 can rotate around the connecting rod 602 to adjust its angle. Several long pressure rollers 102 are installed on the top of the frame 1 and inside the protective cover 4, ensuring that the axis of the long pressure rollers 102 is perpendicular to the direction of the conveyor belt 303 and that their height is adjusted to cooperate with the short pressure rollers 213 to press the plate. A filter table 7 is installed at the output end of the conveyor unit 3, with the top of the filter table 7 tilted. A grid 701 parallel to the output direction is laid on the upper part, and an inclined plate 702 is installed on the lower part, ensuring that debris can slide down the inclined plate 702 to the collection area. An electrical distribution box 101 is installed on the side of the frame 1.Connect motor 1 (202), motor 2 (305), infrared transmitter (402), and control button (403) to distribution box (101) via wires to form a centralized control system. Check the wiring connections for secure connections to prevent leakage or short circuits. After equipment assembly, rotate adjustment turntable (209) to test the smoothness of the up-and-down movement of short pressure roller (213) driven by movable rod (206) and the normal elasticity of spring (211). Manually rotate drive roller (301) to check the smoothness of conveyor belt (303) operation without jamming or deviation. Adjust the angle of chamfer ruler (603) and test the angle locking for secureness. (Use control button 4...) 03. Start motor 1 (202) and motor 2 (305), observe whether the rotation speed of saw blade 203 and the running speed of conveyor belt 303 meet the set values, move infrared emitter 402, test whether the infrared light is aligned with the cutting mark line of the board, adjust it until the mark line coincides with the cutting path of saw blade 203, simulate board conveying, observe whether the long pressure roller 102 and short pressure roller 213 press the board synchronously, and whether the size and angle of the board after cutting meet the accuracy requirements, test the function of filter table 7, put debris onto conveyor belt 303, observe whether the debris falls through grid 701 and slides down inclined plate 702 without accumulation. After the test is completed, adjust the chamfer ruler 6 to the required angle, press the control button 403, and start motor 2 305 and motor 1 202 in sequence. After the equipment runs stably, start feeding. The board moves towards the cutting unit 2 with the conveyor belt 303. First, it passes under the long pressure roller 102. The long pressure roller 102 presses the upper surface of the board at a preset height. When the front end of the board reaches the cutting area, the short pressure roller 213 automatically presses the board with the elastic pressure of the spring 211 and the telescopic rod 210 to ensure that the board does not shift during cutting. The saw blade 203 rotates at high speed to complete the cutting. The cut board continues to move with the conveyor belt 303. 03. The material is conveyed to the filter table 7. The grid 701 blocks the material from stopping, and the debris falls through the gaps in the grid 701 to the inclined plate 702 for collection. Repeat the feeding steps to achieve batch cutting. During the process, pay attention to the alignment of the material. If the angle or size needs to be adjusted, after stopping the machine, reset the chamfer ruler 6 and the infrared position, press the control button 403, and turn off motor 1 202 and motor 2 305 in sequence. After the saw blade 203 has completely stopped rotating, open the protective cover 4 to clean the debris near the saw blade 203. Regularly clean the debris collection box under the inclined plate 702 of the filter table 7 to prevent debris accumulation from affecting the operation of the equipment.
