[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. The automatic cutting device for door and window aluminum profiles can efficiently convey the aluminum profiles to be cut by starting the fifth servo motor to drive the coupling to drive the first conveying roller and the material conveyor belt, greatly improving the efficiency of the preliminary preparation for processing. During the conveying of the aluminum profiles, the sixth servo motor drives the third lead screw to rotate, causing the L-shaped connecting block to drive the first baffle to move downward, accurately resisting and positioning the aluminum profiles. This positioning method solves the problem that the aluminum profiles are always in the conveying state and cannot be cut, ensures the accuracy of the cutting position, effectively improves the cutting accuracy. Moreover, after the aluminum profiles are positioned, the fifth servo motor can be timely turned off to cancel the conveying, facilitating the smooth progress of the subsequent cutting operation, further improving the coherence and automation degree of the entire cutting process, thereby enhancing the production efficiency and reducing the labor cost.

[0021] 2. The automatic cutting device for door and window aluminum profiles, during the conveying of the aluminum profiles, by controlling the start of the fourth servo motor, cleverly utilizes the coordinated operation of the second rotating rod, the second gear, the first transmission belt and the third gear, enabling the first threaded rod to push the fixed connecting plate, and then driving the U-shaped correction plate to move. The design of the limiting plate and the guide rod ensures the smooth movement of the U-shaped correction plate. The synchronous movement of multiple U-shaped correction plates can drive the rotating rollers to accurately clamp both sides of the aluminum profiles. This design can quickly and efficiently complete the calibration and positioning of aluminum profiles with different widths, making them accurately located at the center of the material conveyor belt, not only ensuring the stability during the conveying process, but also providing an accurate reference for the subsequent cutting process, greatly improving the accuracy and efficiency of aluminum profile processing and reducing the scrap rate.

[0022] 3. The automatic cutting device for door and window aluminum profiles, after the aluminum profiles are calibrated and positioned, starts the first servo motor. Through the meshing of the first gear and the rack and the sliding of the track wheel in the track groove, the U-shaped support plate drives the cross beam and the disc cutter to move horizontally, accurately determining the cutting length. Then the air cylinder pushes the pressure wheel to press down the material conveyor belt, making it concave at the cutting position. The third servo motor drives the disc cutter to move downward, and the second servo motor drives it to move horizontally to complete the cutting. This method avoids cutting the material conveyor belt, ensures the normal operation and service life of the equipment. At the same time, the second baffle effectively blocks the flying of the chips generated by cutting, improves the working environment, reduces the cleaning cost, and improves the safety and efficiency of the cutting operation.

[0023] 4. After the aluminum profile is cut by this automatic cutting device for door and window aluminum profiles, reverse the sixth servo motor to move the first baffle upward, and then start the fifth servo motor to drive the material conveyor belt to convey, so that the aluminum profile can be sent to the designated position for subsequent processing, ensuring the continuity of the production process. Moreover, when the fifth servo motor drives the first conveying roller to rotate, the fourth gear will rotate synchronously. Through the transmission of the second transmission belt, the fifth gear drives the rotating brush to rotate. The rotating brush can effectively clean the cutting debris remaining on the surface of the material conveyor belt, avoiding the problem of affecting the subsequent processing accuracy of aluminum profiles due to more debris on the conveyor belt, improving the product quality, reducing the defective rate, and lowering the production cost.

[0024] 5. When conveying aluminum profiles of different weights and shapes by this automatic cutting device for door and window aluminum profiles, the tension of the material conveyor belt can be flexibly adjusted as needed. First, loosen the two nuts, and then use a hex wrench to rotate the hexagon connecting block to drive the second threaded rod to rotate. Since the second threaded rod is rotationally connected to the connecting piece, when rotating, it pushes the connecting piece to move. At this time, the two sliders slide smoothly in the third slide rail to ensure the smooth movement of the connecting piece. The movement of the two connecting pieces drives the second conveying roller to move, realizing the adjustment of the distance between the second conveying roller and the first conveying roller, and then accurately adjusting the tension of the material conveyor belt to ensure the stable conveying of aluminum profiles and improve the accuracy and efficiency of cutting and processing.

[0038] Starting the fifth servo motor 41 to drive the coupling 42 to drive the first conveying roller 43 and the material conveyor belt 56 can efficiently convey the aluminum profiles to be cut. During the conveying process of the aluminum profiles, the sixth servo motor 59 drives the third lead screw 60 to rotate, so that the L-shaped connecting block 62 drives the first baffle 63 to move downwards, accurately resisting and positioning the aluminum profiles. This positioning method solves the problem that the aluminum profiles are always in the conveying state and cannot be cut, and after the aluminum profiles are positioned, the fifth servo motor 41 can be timely turned off to cancel the conveying, which is convenient for the subsequent cutting operation to proceed smoothly.

[0040] During the conveying process of the aluminum profile, by controlling the start of the fourth servo motor 28, the coordinated operation of the second rotating rod 29, the second gear 30, the first transmission belt 32, and the third gear 31 is cleverly utilized, so that the first threaded rod 33 pushes the fixed connection plate 37, and then drives the U-shaped correction plate 36 to move. The design of the limit plate 34 and the guide rod 35 ensures the smooth movement of the U-shaped correction plate 36. The synchronous action of multiple U-shaped correction plates 36 can drive the rotating roller 39 to accurately clamp both sides of the aluminum profile, making it accurately located at the center position of the material conveyor belt 56.

[0042] After the aluminum profile is calibrated and positioned, the first servo motor 8 is started. Through the meshing of the first gear 10 and the rack 4 and the sliding of the track wheel 6 in the track groove 3, the U-shaped support plate 5 drives the cross beam 11 and the disc cutting machine 22 to move horizontally, accurately determining the cutting length. Then, the air cylinder 24 pushes the pressing wheel 25 downward to make the material conveyor belt 56 concave at the cutting position. The third servo motor 18 drives the disc cutting machine 22 to move downward, and the second servo motor 13 drives it to move horizontally to complete the cutting. This method avoids cutting the material conveyor belt 56. At the same time, the second baffle 64 effectively blocks the flying of the chips generated by cutting.

The rotating brush 47 can effectively clean the cutting chips remaining on the surface of the material conveyor belt 56, avoiding the problem of affecting the subsequent processing accuracy of the aluminum profile due to more chips on the conveyor belt.

[0045] Embodiment 5, as Figure 1 、 Figure 2 、 Figure 9 shown, an automatic cutting device for door and window aluminum profiles. Two mounting frames 48 are symmetrically and detachably connected to the left side of the material transporting base platform 1.

[0046] When transporting aluminum profiles of different weights and shapes, the tension of the material conveyor belt 56 can be flexibly adjusted as needed. During specific operations, first loosen the two nuts 55, and then use a hex wrench to rotate the hexagon connecting block 54 to drive the rotation of the second threaded rod 53. Since the second threaded rod 53 is rotatably connected to the connecting member 51, when rotating, it pushes the connecting member 51 to move. At this time, the two sliders 50 slide smoothly in the third slide rail 49 to ensure the smooth movement of the connecting member 51. The movement of the two connecting members 51 drives the movement of the second conveying roller 52, realizing the adjustment of the distance between the second conveying roller 52 and the first conveying roller 43, and then precisely adjusting the tension of the material conveyor belt 56 to ensure the stable transportation of aluminum profiles.

[0047] It should be noted that the present invention is an automatic cutting device for door and window aluminum profiles. When in use, start the fifth servo motor 41 to drive the coupling 42 to drive the first conveying roller 43 and the material conveyor belt 56 for transportation. Then move one end of the aluminum profile to be cut and processed to the upper end of the material conveyor belt 56 for transportation. At the same time, control the sixth servo motor 59 to start and drive the third lead screw 60 to rotate. At this time, the L-shaped connecting block 62 will drive the first baffle 63 to move downward as the third lead screw 60 rotates. After moving to the lowest position, the first baffle 63 will resist the aluminum profile during transportation. After one end of the aluminum profile abuts against the first baffle 63, the fifth servo motor 41 can be turned off to cancel its transportation. Then the aluminum profile can be cut, solving the problem that the aluminum profile is always in a transportation state and cannot be cut.

[0048] While transporting the aluminum profile, control the fourth servo motor 28 to start and drive the second rotating rod 29 to rotate. At this time, the two second gears 30 will rotate synchronously as the second rotating rod 29 rotates. At this time, under the driving action of the two first transmission belts 32, the two third gears 31 will be driven to rotate synchronously. Since the third gear 31 is rotatably connected to the L-shaped mounting plate 26 and the first threaded rod 33 is threadedly connected to the third gear 31, when the third gear 31 rotates, it will drive the first threaded rod 33 to push the fixed connection plate 37 towards the center position, and at the same time drive the two U-shaped calibration plates 36 to move. Here, under the action of the limiting plate 34 and the guide rod 35, the two U-shaped calibration plates 36 can move more smoothly. When the multiple U-shaped calibration plates 36 move synchronously, they will drive the multiple rotating rollers 39 to move until the multiple rotating rollers 39 clamp both sides of the aluminum profile, then the calibration and positioning of aluminum profiles of different widths can be completed, making it in the center position of the material conveyor belt 56. At the same time, the material conveyor belt 56 transports the aluminum profile, and after transporting it to the designated position, it can be cut and processed.

[0049] After calibrating and positioning the aluminum profile, control the first servo motor 8 to start and drive the first rotating rod 9 and the first gear 10 to rotate. Since the first gear 10 meshes with the rack 4 at one end of the first vertical plate 2, and the track wheels 6 at the lower end of the U-shaped support plate 5 horizontally slide in the track groove 3 opened at the other end of the first vertical plate 2, when the first servo motor 8 drives the first gear 10 to rotate, it will drive the U-shaped support plate 5 to move horizontally. When the two U-shaped support plates 5 move synchronously, they will drive the cross beam 11 and the disk cutting machine 22 installed on its upper end to move horizontally. After moving to a position where the distance between the disk cutting machine 22 and the first baffle 63 is the required cutting length of the aluminum profile, turn off the first servo motor 8. Then, push the pressure wheel 25 downward by the cylinder 24. Until the pressure wheel 25 contacts the surface of the material conveyor belt 56 and continues to move downward, it will press down the material conveyor belt 56. At this time, the material conveyor belt 56 below the cutting position of the aluminum profile will sink downward. Then, start the third servo motor 18 to drive the second lead screw 19 to rotate. The moving plate 20 will drive the disk cutting machine 22 to move downward as the second lead screw 19 rotates. After moving to the lowest position, start the disk cutting machine 22. At the same time, start the second servo motor 13 to drive the first lead screw 14 to rotate. At this time, the moving block 15 will drive the U-shaped connecting plate 17 and the disk cutting machine 22 to move horizontally as the first lead screw 14 rotates. When the disk cutting machine 22 moves horizontally, it can cut the aluminum profile. Since the material conveyor belt 56 below the cutting position of the aluminum profile is in a sunken state, it is possible to avoid cutting the material conveyor belt 56 during cutting. At the same time, under the action of the second baffle 64, it can effectively solve the problem of debris flying everywhere when cutting the aluminum profile.

[0050] After the aluminum profile is cut, reverse the sixth servo motor 59 to drive the first baffle 63 to move upward. Then, start the fifth servo motor 41 to continue driving the material conveyor belt 56 to convey, and the aluminum profile can be conveyed to the designated position for subsequent processing. When the fifth servo motor 41 drives the first conveying roller 43 to rotate, it will synchronously drive the fourth gear 44 to rotate. At this time, under the driving action of the second transmission belt 45, the fifth gear 46 will also rotate synchronously, and at the same time drive the rotating brush 47 to rotate. When the rotating brush 47 rotates, it can clean the cutting debris remaining on the surface of the material conveyor belt 56, avoiding too much debris on the surface of the material conveyor belt 56 affecting the subsequent processing accuracy when conveying the aluminum profile later.

[0051] When transporting aluminum profiles of different weights and shapes, the tension of the material conveyor belt 56 can be adjusted according to specific circumstances. During the adjustment, first loosen the two nuts 55, and then use a hexagon wrench to drive the hexagon connecting block 54 to rotate. When the hexagon connecting block 54 rotates, it will drive the second threaded rod 53 to rotate. Since the other end of the second threaded rod 53 is rotatably connected to the connecting member 51, when the second threaded rod 53 rotates, it will push the connecting member 51 to move. When the connecting member 51 moves, the two sliders 50 will move along with it within the third slide rail 49, so that the movement of the connecting member 51 can be made more stable. When the two connecting members 51 move, they will drive the second conveying roller 52 between them to move, so that the distance between the second conveying roller 52 and the first conveying roller 43 can be adjusted, and thus the tension of the material conveyor belt 56 can be adjusted.
