[0002] In the field of door and window processing, high-precision cutting is a key link to ensure product quality, which usually relies on cutting equipment installed with high-performance cutting blades. However, high-precision cutting blades are very expensive, and their cutting edges will gradually wear and blunt during continuous cutting, resulting in rough cutting surface, decreased precision, and even the need to frequently replace new blades.

[0003] Most existing cutting equipment has single function and lacks online maintenance capability for expensive blades. When the blade is blunted, the operator usually needs to stop the machine and disassemble it to send it to a special blade grinding equipment for grinding, or directly replace a new blade. This offline maintenance method not only has a complicated process, consumes time and effort, and reduces equipment utilization, but more importantly, disassembling and reinstalling the blade can easily introduce installation errors, affecting the cutting precision of the same batch of processing; at the same time, a large amount of metal debris generated during cutting not only pollutes the working environment, but also may splash into the equipment, accelerating equipment wear, and even posing a threat to the safety of the operator.

[0063] The driving mechanism three 6 drives the sliding seat 207 to slide, so as to facilitate adjustment of the position of the machining platform 2 to adapt to cutting of workpieces of different lengths; the protective cover 203 cooperates with the protective cover 401 to double-block debris splashing and improve safety; the electric push rod 208 can firmly fix the workpiece to avoid that the workpiece is displaced during cutting to cause uneven stress of the saw blade body 304 and abrasion; the air pipe through groove 205 provides an installation channel for the debris collecting pipe 504 to ensure normal operation of the collecting system; the torque sensor 306 ensures that the protection assembly 4 is started only after the saw blade body 304 reaches the set rotating speed, so as to avoid interference between the protection assembly 4 and the saw blade at low rotating speed.

[0064] Further, the driving mechanism three 6 comprises a threaded rod 601, the threaded rod 601 is rotatably installed at the top of the base 1 below the machining platform 2, one end of the threaded rod 601 is connected to the output end of the third motor 602, the fixed end of the third motor 602 is connected to one side of the top of the base 1 away from the machining platform 2, one side of the base 1 is further provided with an operation panel 7 for controlling the whole device, the top of the base 1 is provided with a state display screen 8 for monitoring the running state of the equipment, and the input end of the third motor 602 is electrically connected with the external power supply.

[0066] Working principle: The operator starts the equipment through the operation panel 7, places the door and window workpiece on the surface of the machining platform 2, controls the electric push rod 208 to extend, and fixes the workpiece on the machining platform 2 to avoid displacement of the workpiece during cutting. Then the third motor 602 of the driving mechanism three 6 drives the threaded rod 601 to rotate, so that the sliding seat 207 slides along the top of the base 1, adjusting the relative position of the machining platform 2 and the saw blade body 304 until the workpiece to be cut aligns with the cutting groove 202.

[0067] The first motor 303 and the second motor 305 are started, the first motor 303 drives the connecting rotating rod 302 to rotate, and then drives the saw blade body 304 to rotate with the connecting rotating rod 302, the second motor 305 drives the saw blade body 304 to rotate for cutting; the torque sensor 306 detects the rotating speed of the saw blade body 304 in real time, when the rotating speed reaches 4000 rpm, the equipment automatically starts the protection assembly 4. At this time, the telescopic rod 4101 of the driving mechanism one 41 is elongated, pushing the moving seat 4102 to slide along the sliding groove 204 on the top of the installation partition plate 206, driving the protection cover 401 fixed by the installation clamping seat 4104 and the installation groove 405 to move, the displacement sensor 409 detects the distance between the protection cover 401 and the saw blade body 304 in real time, ensuring that there is no collision between the two and that the protection cover 401 can effectively cover the side of the saw blade body 304 away from the cutting groove 202.

[0068] During cutting, the cutting-out groove 404 of the protection cover 401 is attached to the surface of the saw blade body 304 to prevent debris from splashing; at the same time, the suction pump 505 of the collecting assembly 5 is started, and the debris generated by the saw blade body 304 cutting is collected to the discharge hole 408 under the action of the airflow through the material guide groove 402 on the inner wall of the protection cover 401, and then enters the collecting tank 501 through the debris collecting pipe 504, and the filter plate 503 filters the debris to avoid affecting the operation of the equipment.

[0069] When the saw blade body 304 needs to be sharpened, the air pump 4309 of the driving mechanism two 43 is started, air is filled into the cylinder body 4301 through the connecting air pipe 4303, the piston 4304 is pushed to move the connecting column 4305 and the mounting sleeve 4306, the sharpening block 4201 on the mounting sleeve 4306 moves to the saw blade body 304; the displacement sensor two 4202 detects the distance between the sharpening block 4201 and the saw blade body 304 in real time, ensures that the sharpening block 4201 and the saw blade body 304 maintain a suitable sharpening gap, and avoids excessive wear of the saw blade; at the same time, the scraper 4307 on the mounting sleeve 4306 moves with the mounting sleeve 4306, and the debris attached to the surface of the saw blade body 304 is scraped off, so that the sharpening effect is ensured. After cutting is completed, the motor and the air pump 505 are turned off, the tank cover 502 of the collecting tank 501 is opened to clean the debris, and the state display screen 8 displays the equipment operation state in real time, so that the operator can monitor.
