[0002] Cutting machines are indispensable equipment for some light industries. Traditionally, cutting machines are machines that use the force of machine movement to pressurize the die to cut materials. Modern cutting machines have undergone some changes, and advanced technologies such as high-pressure water jets and ultrasonic waves have begun to be used in leather punching technology, but people still classify these devices as cutting machines. Cutting machines use a four-plus-one process, and the 4+1 processing process is better than 5-axis processing, and tool life, cutting time, and workpiece surface roughness can all be improved to a certain extent.

[0003] The cutting machine in the prior art has the following disadvantages: 1. When the workpiece is cut by the cutting machine, cutting debris is generated during the cutting process, and larger fragments remain on the surface of the processing table after cutting, affecting subsequent processing, and people need to manually clean the processing table; 2. When the cutting machine continuously processes the workpiece, when one end of the workpiece is cut, the other end is prone to warp up, affecting the processing effect. Therefore, improvements are made to the above problems. Utility Model Content

[0004] The purpose of the utility model is to provide a CNC four-plus-one cutting machine in order to solve the above-mentioned problem. The components inside the suction hood and the movable scraper cooperate to clean the surface of the processing table after processing to prevent waste chips from affecting subsequent processing; rubber rollers and rollers fix the workpiece on the processing table to prevent the workpiece from warping during processing.

[0005] The utility model achieves the above-mentioned purpose through the following technical scheme. A CNC four-plus-one cutting machine includes a bed, the bed is slidably connected to a processing frame, the bed is equipped with a processing table, a suction hood is installed under the processing table, a groove is opened on the surface of the processing table, a scraper is slidably connected to the surface of the processing table, the scraper is rotatably connected to a rotating plate through a rotating rod, the top of the rotating rod passes through the scraper, an electric push rod b is installed at the bottom end of the processing frame, the electric push rod b is installed with a bracket a, the bracket a is rotatably connected to a roller, the processing frame is installed with a connecting frame, the connecting frame is installed with a hydraulic cylinder, the hydraulic cylinder is installed with a bracket b, and the bracket b is rotatably connected to a rubber roller.

[0006] Preferably, the processing table is installed with a limit plate, the limit plate is installed with a motor, and the output end of the motor is fixedly connected with a screw.

[0007] Preferably, the screw is threadedly connected to a scraper frame, and electric push rods a are installed on both sides of the scraper frame.

[0008] Preferably, the electric push rod a is connected with a vertical rod through it, the vertical rod is slidably connected with a push plate, and the push plate is fixedly connected to the top end of the rotating rod.

[0009] Preferably, a filter is installed in the air suction hood, and the filter is located above the fan.

[0010] Preferably, a collecting rack is installed in the bed, the collecting rack is located below the groove, and mesh holes are opened on the surface of the processing table.

[0011] Preferably, the processing frame is slidably connected to a machine head, and the machine head is located above the processing table.

[0012] The beneficial effects of the utility model are:

[0013] The components inside the suction hood and the movable scraper cooperate to clean the surface of the processing table after processing to prevent waste chips from affecting subsequent processing; there are mesh holes on the surface of the processing table. When the workpiece is processed, the fan in the suction hood starts to continuously extract the air above, that is, suction is generated at the mesh holes on the surface of the processing table, which can continuously absorb the cutting chips on the surface of the processing table. The fine cutting chips enter the suction hood with the air under the action of suction, and are intercepted and filtered by the filter. After processing, the workpiece is removed, and the motor on the limit plate rotates to drive the connected screw to rotate. The rotation of the screw drives the connected scraper to scrape along the surface of the processing table, which can push large pieces of chips from the surface of the processing table. The scraper moves forward, and the scraper continues to move forward to push the debris to the groove. The debris enters the groove and falls into the collection frame. The electric push rod a on the scraper extends. When the electric push rod a continues to extend, the vertical rod connected to it slides along the push plate, and the push plate rotates outward around the scraper with the rotating rod as the axis. The rotation of the rotating rod drives the connected rotating plate to rotate inward. The inward rotation of the rotating plate pushes the waste chips on both sides to move inward into the groove, and falls along the groove into the collection box for collection. After cleaning, the electric push rod a shortens and drives the rotating plate to return to its original state. The motor reverses and drives the scraper to move backward to return to its original state. The processing table can be cleaned by the cooperation of the components inside the suction hood and the scraper.

[0014] The rubber roller and the wheel fix the workpiece on the processing table to prevent the workpiece from tilting during processing; when the workpiece is cut horizontally, the hydraulic cylinder on the connecting frame behind the processing frame extends, and the extension of the hydraulic cylinder pushes the connected bracket b downward, and the bracket b continues to move downward to drive the connected rubber roller to move downward and closely contact the surface of the workpiece, which can press the back of the workpiece to prevent the back of the workpiece from tilting and affecting the cutting when the front head cuts the workpiece horizontally. When the workpiece is cut longitudinally, the electric push rod b installed under the processing frame extends, and the extension of the electric push rod b pushes the connected bracket a downward, and the bracket a moves downward to drive the connected roller to move downward until the roller is in contact with the surface of the workpiece. When the processing frame drives the head to move forward and backward to cut the workpiece longitudinally, the roller continues to slide along the surface of the workpiece while pressing the workpiece to prevent it from tilting. The workpiece can be fixed by the roller and the rubber roller to prevent it from tilting during processing. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] Specifically, the processing table 2 is installed with a limit plate 10, which can facilitate the installation of the motor 19. The limit plate 10 is installed with the motor 19, and the output end of the motor 19 is fixedly connected to the screw 3. The rotation of the motor 19 drives the connected screw 3 to rotate.

[0023] Specifically, the screw rod 3 is threadedly connected to the scraper frame 1, and the rotation of the screw rod 3 drives the connected scraper frame 1 to move forward and backward. Electric push rods a7 are installed on both sides of the scraper frame 1, and the scraper frame 1 can fix the position of the electric push rods a7.
