[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.

[0050] Further, the sliding seat 207 is driven by the third driving mechanism 6 and is slidingly installed on the top of the base 1. The mounting cover 201 is fixedly installed on one side of the sliding seat 207. The top of the sliding seat 207 is fixedly installed with the protective cover 203 away from one side of the mounting cover 201. The protective cover 203 is used to avoid the splashing of debris during cutting. The mounting cover 201 is fixedly installed with the electric push rod 208 away from the protective cover 203. The workpiece is fixed on the surface of the machining platform 2 through the electric push rod 208. The surface of the mounting partition plate 206 is provided with the air pipe through groove one 205 at a position corresponding to the debris collecting pipe 504, so that the debris collecting pipe 504 penetrates the mounting partition plate 206. The torque sensor 306 is arranged on one side of the cutting groove 202. The torque sensor 306 is used to detect the rotating speed of the saw blade body 304. When the rotating speed of the saw blade body 304 reaches 4000 rpm, the protection assembly 4 is started. The input end of the electric push rod 208 is electrically connected with the external power supply.

[0051] The third driving mechanism 6 drives the sliding seat 207 to slide, so as to adjust the position of the machining platform 2 and adapt to the cutting of workpieces with different lengths. The protective cover 203 cooperates with the protective cover 401 to double-block the splashing of debris and improve safety. The electric push rod 208 can firmly fix the workpiece, so as to avoid the displacement of the workpiece during cutting and the uneven stress of the saw blade body 304 and abrasion. The air pipe through groove one 205 provides an installation channel for the debris collecting pipe 504 and ensures the normal operation of the collecting system. The torque sensor 306 ensures that the protection assembly 4 is started only after the rotating speed of the saw blade body 304 reaches the set rotating speed, so as to avoid the interference between the protection assembly 4 and the saw blade at low rotating speed.

[0052] Further, the third driving mechanism 6 includes a threaded rod 601. The threaded rod 601 is rotatably installed on 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. The base 1 is also provided with an operation panel 7 for controlling the entire device. The top of the base 1 is provided with a state display screen 8 for monitoring the running state of the equipment. The input end of the third motor 602 is electrically connected with the external power supply.

[0053] The third motor 602 drives the threaded rod 601 to rotate, so as to realize the stable sliding of the sliding seat 207, ensure the accurate adjustment of the position of the machining platform 2, and improve the cutting precision. The operation panel 7 is convenient for the operator to centrally control the equipment and reduces the operation difficulty. The state display screen 8 displays the running state of the equipment in real time, so as to facilitate the operator to timely find problems such as abnormal rotating speed of the saw blade body 304 and failure of the protection assembly 4.

[0054] 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, fixes the workpiece on the machining platform 2, avoids the displacement of the workpiece in the cutting process. 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, adjusts the relative position of the machining platform 2 and the saw blade body 304, until the cutting part of the workpiece is aligned with the cutting groove 202.

[0055] Start the first motor 303 and the second motor 305, the first motor 303 drives the connecting rotating rod 302 to adjust the cutting angle of the saw blade body 304, and the second motor 305 drives the saw blade body 304 to rotate; the torque sensor 306 detects the rotating speed of the saw blade body 304 in real time, and when the rotating speed reaches 4000 revolutions / hour, the equipment automatically starts the protection assembly 4. At this time, the telescopic rod one 4101 of the driving mechanism one 41 is elongated, pushes the moving seat 4102 to slide along the sliding groove 204 on the top of the installation partition plate 206, drives the protection cover 401 fixed through the installation clamp seat 4104 and the installation groove 405 to move, and the displacement sensor one 409 detects the distance between the protection cover 401 and the saw blade body 304 in real time, so that the two do not collide and the protection cover 401 can effectively cover the side of the saw blade body 304 away from the cutting groove 202.

[0056] During the cutting process, the cutting slot 404 of the protection cover 401 is attached to the surface of the saw blade body 304, preventing 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 through the guide chute 402 on the inner wall of the protection cover 401 under the action of the airflow, 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.

[0057] When it is necessary to sharpen the saw blade body 304, the air pump 4309 of the driving mechanism two 43 is started, air is filled into the air cavity 4301 through the connecting air pipe 4303, the piston 4304 is pushed to drive the connecting column 4305 and the installation sleeve 4306 to move, so that the sharpening block 4201 on the installation sleeve 4306 approaches 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, so that the sharpening block 4201 and the saw blade body 304 maintain a suitable sharpening gap, avoiding excessive wear of the saw blade; at the same time, the scraper 4307 on the installation sleeve 4306 moves with the installation sleeve 4306, and the debris attached to the surface of the saw blade body 304 is scraped off, ensuring the sharpening effect. After cutting is completed, the motor and the suction 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 running state of the equipment in real time, facilitating the monitoring of the operator.
