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

[0020] 1. The automatic cutting device for aluminum profiles for doors and windows 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 process of the aluminum profiles, the sixth servo motor drives the third screw to rotate, so that the L-shaped connecting block drives the first baffle to move down, and accurately blocks and positions the aluminum profiles. This positioning method solves the problem that the aluminum profiles are always in a conveying state and cannot be cut, ensures the accuracy of the cutting position, and effectively improves the cutting accuracy. Moreover, after the positioning of the aluminum profiles is completed, the fifth servo motor can be turned off in time to cancel the conveying, which is convenient for the smooth progress of subsequent cutting operations, further improving the continuity and automation of the entire cutting process, thereby improving production efficiency and reducing labor costs.

[0021] 2. The automatic cutting device for aluminum profiles for doors and windows controls the start of the fourth servo motor during the conveying process of aluminum profiles, and cleverly utilizes the coordinated operation of the second rotating rod, the second gear, the first transmission toothed belt and the third gear, so that the first threaded rod pushes the fixed plate, thereby driving the U-shaped correction plate to move. The design of the limit 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 roller to accurately clamp the two sides of the aluminum profile. This design can quickly and efficiently complete the calibration and positioning of aluminum profiles of different widths, so that they are accurately located in the center of the material conveyor belt, which not only ensures the stability during the conveying process, but also provides an accurate benchmark for subsequent cutting processing, greatly improving the precision and efficiency of aluminum profile processing and reducing the scrap rate.

[0022] 3. After the aluminum profile is calibrated and positioned, the automatic cutting device for aluminum profiles for doors and windows 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 crossbeam and the disc cutter to move horizontally, accurately determining the cutting length. Then the 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, ensuring the normal operation and service life of the equipment. At the same time, the second baffle effectively blocks the splashing of debris 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 cutting is completed, the automatic cutting device for doors and windows aluminum profiles reverses the sixth servo motor to move the first baffle up, and then starts the fifth servo motor to drive the material conveyor belt to convey the aluminum profile to the designated location for subsequent processing, thereby ensuring the continuity of the production process. Moreover, when the fifth servo motor drives the first conveyor roller to rotate, the fourth gear will rotate synchronously, and the fifth gear will drive the rotating brush to rotate through the transmission of the second transmission toothed belt. The rotating brush can effectively clean the cutting debris remaining on the surface of the material conveyor belt, thereby avoiding the problem of affecting the subsequent aluminum profile processing accuracy due to a large amount of debris on the conveyor belt, thereby improving product quality, reducing the defective rate, and reducing production costs.

[0024] 5. The automatic cutting device for aluminum profiles for doors and windows can flexibly adjust the tension of the material conveyor belt as needed when conveying aluminum profiles of different weights and shapes. First, loosen the two nuts, and then use a hexagonal wrench to rotate the hexagonal connecting block to drive the second threaded rod to rotate. Since the second threaded rod is rotatably connected to the connecting piece, the connecting piece is pushed to move when rotating. At this time, the two sliders slide smoothly in the third slide rail to ensure that the connecting piece moves smoothly. The movement of the two connecting pieces drives the second conveying roller to move, thereby adjusting 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 stable conveying of aluminum profiles and improve the accuracy and efficiency of cutting processing.

[0038] Starting the fifth servo motor 41 drives the coupling 42 to drive the first conveying roller 43 and the material conveyor belt 56, so as to efficiently convey the aluminum profile to be cut. During the conveying process of the aluminum profile, the sixth servo motor 59 drives the third screw 60 to rotate, so that the L-shaped connecting block 62 drives the first baffle 63 to move downward, and accurately blocks and positions the aluminum profile. This positioning method solves the problem that the aluminum profile is always in a conveying state and cannot be cut. Moreover, after the positioning of the aluminum profile is completed, the fifth servo motor 41 can be turned off in time to cancel the conveying, so as to facilitate the smooth progress of subsequent cutting operations.

The design of the limit plate 34 and the guide rod 35 ensures that the U-shaped correction plate 36 moves smoothly. The synchronous action of multiple U-shaped correction plates 36 can drive the rotating rollers 39 to accurately clamp the two sides of the aluminum profile, so that it is accurately located at the center of the material conveyor belt 56.

[0041] Embodiment three, as Figure 1-Figure 5 As shown, an automatic cutting device for aluminum profiles for doors and windows is provided, wherein two first vertical plates 2 are symmetrically welded to the upper end of a material transport base platform 1, a rack 4 is detachably connected to one end of the first vertical plate 2, two track wheels 6 are detachably mounted on the lower end of a U-shaped support plate 5, and the track wheel 6 slides horizontally in a track groove 3, a first fixed plate 7 is welded to one end of the U-shaped support plate 5, a first servo motor 8 is detachably connected to the upper end of the first fixed plate 7, the two first servo motors 8 have the same rotation speed and opposite rotation directions, an output end of the first servo motor 8 passes through the first fixed plate 7 and is detachably connected to a first rotating rod 9, a first gear 10 is welded to the outer surface of the first rotating rod 9, the first gear 10 is meshed with the rack 4, a crossbeam 11 is detachably connected to the upper ends of the two U-shaped support plates 5, two second vertical plates 12 are symmetrically welded to the upper end of the crossbeam 11, a second servo motor 13 is detachably connected to the front end of a second vertical plate 12, and an output end of the second servo motor 13 passes through the second vertical plate 12 and is detachably connected to the first screw rod 14 The movable block 15 is threadedly connected to the outer surface of the first screw rod 14, the two first slide rails 16 are detachably connected to the upper end of the beam 11, the movable block 15 is slidably connected to the two first slide rails 16, the U-shaped connecting plate 17 is welded to one side of the movable block 15, the third servo motor 18 is detachably connected to the top of the U-shaped connecting plate 17, the output end of the third servo motor 18 passes through the U-shaped connecting plate 17 and is detachably connected to the second screw rod 19, the movable plate 20 is threadedly connected to the outer surface of the second screw rod 19, the second slide rail 21 is detachably connected to one side of the U-shaped connecting plate 17, the movable plate 20 is slidably connected to the surface of the second slide rail 21, the disc cutter 22 is detachably connected to one side of the movable plate 20, the two second fixed plates 23 are symmetrically welded to one side of the beam 11, the cylinder 24 is detachably connected to the upper end of the second fixed plate 23, the output end of the cylinder 24 passes through the second fixed plate 23 and is detachably connected to the pressure wheel 25, and the two second baffles 64 are symmetrically welded to the upper end of the material transport base platform 1.

[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 crossbeam 11 and the disc cutter 22 to move horizontally, and the cutting length is accurately determined. Then the cylinder 24 pushes the pressure wheel 25 to press down the material conveyor belt 56, making it concave at the cutting position. The third servo motor 18 drives the disc cutter 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 splashing of debris generated by cutting.

[0043] Embodiment 4, as Figure 1 , Figure 2 , Figure 8 As shown, an automated cutting device for aluminum profiles for doors and windows is provided, wherein a third fixed plate 40 is detachably connected to one side of a material transport base platform 1, a fifth servo motor 41 is detachably connected to the upper end of the third fixed plate 40, an output end of the fifth servo motor 41 is detachably connected to a first conveying roller 43 via a coupling 42, a fourth gear 44 is welded to an outer surface of the first conveying roller 43, a second transmission toothed belt 45 is meshed with an outer surface of the fourth gear 44, an inner surface of the other end of the second transmission toothed belt 45 is meshed with a fifth gear 46, and the fifth gear 46 is welded to an outer surface of a rotating brush 47.

[0044] After the aluminum profile is cut, the sixth servo motor 59 is reversed to move the first baffle 63 upward, and the fifth servo motor 41 is started to drive the material conveyor belt 56 to convey the aluminum profile to a designated location for subsequent processing. Moreover, when the fifth servo motor 41 drives the first conveying roller 43 to rotate, the fourth gear 44 will rotate synchronously. Through the transmission of the second transmission toothed belt 45, the fifth gear 46 drives the rotating brush 47 to rotate. The rotating brush 47 can effectively clean the cutting debris remaining on the surface of the material conveyor belt 56, thereby avoiding the problem of affecting the subsequent aluminum profile processing accuracy due to a large amount of debris on the conveyor belt.

[0045] Embodiment 5, as Figure 1 , Figure 2 , Fig. 9 As shown, an automated cutting device for aluminum profiles for doors and windows is provided, wherein two mounting frames 48 are symmetrically and detachably connected to the left side of a material transport base platform 1, a third slide rail 49 is detachably installed in the mounting frame 48, a slider 50 is slidably connected to the third slide rail 49, a connector 51 is welded to the front ends of the two sliders 50, a second conveying roller 52 is rotatably connected between the two connectors 51, a second threaded rod 53 is rotatably connected to one side of the connector 51, a hexagonal connecting block 54 is welded to the other end of the second threaded rod 53, and two nuts 55 are both threadedly connected to the outer surface of the second threaded rod 53.

[0046] When conveying aluminum profiles of different weights and shapes, the tension of the material conveyor belt 56 can be flexibly adjusted as needed. During the specific operation, first loosen the two nuts 55, and then use a hexagonal wrench to rotate the hexagonal connecting block 54 to drive the second threaded rod 53 to rotate. Since the second threaded rod 53 is rotatably connected to the connecting member 51, the connecting member 51 is pushed to move during rotation. At this time, the two sliders 50 slide smoothly in the third slide rail 49 to ensure that the connecting member 51 moves smoothly. The movement of the two connecting members 51 drives the second conveying roller 52 to move, thereby adjusting the distance between the second conveying roller 52 and the first conveying roller 43, and then accurately adjusting the tension of the material conveyor belt 56 to ensure stable conveying of the aluminum profiles.

[0047] It should be noted that the present invention is an automated cutting device for aluminum profiles for doors and windows. When in use, the fifth servo motor 41 is started to drive the coupling 42 to drive the first conveying roller 43 and the material conveyor belt 56 for conveying, and then one end of the aluminum profile to be cut is moved to the upper end of the material conveyor belt 56 for conveying, and at the same time, the sixth servo motor 59 is controlled to start and drive the third screw rod 60 to rotate. At this time, the L-shaped connecting block 62 will drive the first baffle 63 to move downward with the rotation of the third screw rod 60. After moving to the lowest point, the first baffle 63 will resist the aluminum profile being conveyed. After one end of the aluminum profile resists the first baffle 63, the fifth servo motor 41 can be turned off to cancel its conveying, and then the aluminum profile can be cut, which solves the problem that the aluminum profile is always in a conveying state and cannot be cut.

[0048] When the aluminum profile is conveyed, the fourth servo motor 28 is controlled to start and drive the second rotating rod 29 to rotate. At this time, the two second gears 30 will rotate synchronously with the rotation of the second rotating rod 29. At this time, under the transmission action of the two first transmission toothed belts 32, the two third gears 31 will be synchronously driven to rotate. Since the third gear 31 is rotatably connected to the L-shaped mounting plate 26, and the first threaded rod 33 is internally threadedly connected to the third gear 31, when the third gear 31 rotates, the first threaded rod 33 will be driven to push the fixed plate 37 to move toward the center position, and at the same time, the two U-shaped correction plates 36 will be driven to move. Here, under the action of the limit plate 34 and the guide rod 35, the two U-shaped correction plates 36 can move more smoothly. When multiple U-shaped correction plates 36 move synchronously, they will drive multiple rotating rollers 39 to move. Until the multiple rotating rollers 39 clamp the two sides of the aluminum profile, the calibration and positioning of the aluminum profiles of different widths can be completed, so that it is in the center position of the material conveyor belt 56. At the same time, the material conveyor belt 56 conveys the aluminum profile, and it can be cut and processed after being conveyed to the specified position.

[0049] After calibrating and positioning the aluminum profile, the first servo motor 8 is controlled to start and drive the first rotating rod 9 and the first gear 10 to rotate. Since the first gear 10 is meshed with the rack 4 at one end of the first vertical plate 2, and the track wheel 6 at the lower end of the U-shaped support plate 5 slides horizontally 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 crossbeam 11 and the disc cutter 22 installed on the upper end thereof to move horizontally. After moving to the distance between the disc cutter 22 and the first baffle 63 to be the required aluminum profile cutting length, the first servo motor 8 is turned off, and then the pressure wheel 25 is pushed downward by the cylinder 24 until the pressure wheel 25 contacts the surface of the material conveyor belt 56 and continues to move downward to press down the material conveyor belt 56. At this time, the aluminum profile The material conveyor belt 56 below the material cutting position will be recessed downward, and then the third servo motor 18 will be started to drive the second screw rod 19 to rotate. The movable plate 20 will drive the disc cutter 22 to move downward as the second screw rod 19 rotates. After moving to the lowest point, the disc cutter 22 is started, and the second servo motor 13 is started to drive the first screw rod 14 to rotate. At this time, the movable block 15 will drive the U-shaped connecting plate 17 and the disc cutter 22 to move horizontally as the first screw rod 14 rotates. The disc cutter 22 can cut the aluminum profile when it moves horizontally. Since the material conveyor belt 56 below the aluminum profile cutting position is in a recessed state, the material conveyor belt 56 can be avoided from being cut during cutting. At the same time, under the action of the second baffle 64, the problem of debris splashing around when cutting the aluminum profile can be effectively solved.

[0050] After the cutting of the aluminum profile is completed, the sixth servo motor 59 is reversed to drive the first baffle 63 to move upward, and then the fifth servo motor 41 is started to continue to drive the material conveyor belt 56 to convey the aluminum profile 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 transmission action of the second transmission toothed belt 45, the fifth gear 46 will also rotate synchronously, and at the same time drive the rotating brush 47 to rotate. The rotating brush 47 can clean the cutting debris remaining on the surface of the material conveyor belt 56 when rotating, so as to avoid a lot of debris on the surface of the material conveyor belt 56 affecting the subsequent processing accuracy when the aluminum profile is subsequently conveyed.

[0051] When conveying aluminum profiles of different weights and shapes, the tension of the material conveyor belt 56 can be adjusted according to the specific situation. When adjusting, first loosen the two nuts 55, and then use a hexagonal wrench to drive the hexagonal connecting block 54 to rotate. When the hexagonal 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 accordingly in the third slide rail 49, so that the movement of the connecting member 51 can be 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 then the tension of the material conveyor belt 56 can be adjusted.
