[0026] To make the technical problems, technical solutions and beneficial effects of the utility model clearer, the utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0027] The embodiments provided by this utility model are as follows: Figures 1-6 As shown, an automatic feeding slitting machine includes a picking platform 10. One end of the picking platform 10 is provided with a fixed feeding component 20 and an input conveyor 30. The end of the input conveyor 30 away from the picking platform 10 is provided with a centering positioning platform 40, which is used to center the aluminum plate conveyed by the input conveyor 30. The end of the centering positioning platform 40 away from the input conveyor 30 is provided with a slitting component 50, which is used to cut the aluminum plate into several aluminum strips. The end of the slitting component 50 away from the input conveyor 30 is provided with an output conveyor 60.

[0028] The unloading assembly 20 includes a base 21, a first drive motor 22 is fixedly installed inside the base 21, a rotating column 23 that rotates around its own axis is vertically installed on the top of the base 21, the output end of the first drive motor 22 is fixedly connected to the rotating column 23, a rotating table 24 is horizontally fixedly installed on the top of the rotating column 23, a rotating frame 25 is horizontally fixedly installed on the rotating table 24, a second drive motor 26 is horizontally fixedly installed on the rotating frame 25, a lead screw 27 is rotatably connected to the rotating frame 25, the output end of the second drive motor 26 is fixedly connected to one end of the lead screw 27, and a conveying assembly 28 is threadedly connected to the lead screw 27. The conveying assembly 28 is used to pick up the aluminum plate on the worktable 10.

[0029] In use, external transport equipment stacks and transports aluminum plates onto the retrieval platform 10. The second drive motor 26 on the rotating frame 25 starts, driving the lead screw 27 to rotate around its own axis. The lead screw 27 then moves the conveying assembly 28 directly above the aluminum plates, picking up the aluminum plates from the top of the stack. Then, the first drive motor 22 inside the base 21 starts, driving the rotating column 23 to rotate around its own axis. The rotating column 23, through the rotating platform 24, drives the rotating frame 25 to rotate, achieving horizontal rotation of the aluminum plates during transport. Finally, the second drive motor 26 drives the lead screw 27 to rotate, thereby... The conveying assembly 28 moves to directly above the input conveyor 30 and smoothly places the aluminum plate down. Then, the input conveyor 30 moves the aluminum plate on it towards the centering positioning table 40. When the aluminum plate moves onto the centering positioning table 40, the centering positioning table 40 centers and aligns the aluminum plate. Under the action of the input conveyor 30, the aluminum plate continues to move towards the slitting assembly 50. The aluminum plate enters the slitting assembly 50, and the slitting assembly 50 cuts the aluminum plate into several aluminum strips. The cut aluminum strips move to the output conveyor 60 under the action of the input conveyor 30, and then the output conveyor 60 drives the processed aluminum strips to the next processing area.

[0030] Preferably, the conveying assembly 28 includes a conveying platform 281, a conveying connecting rod 282 fixedly installed on the top of the conveying platform 281, the conveying connecting rod 282 being threadedly connected to the lead screw 27, a vertically downward cylinder 283 fixedly installed at the bottom of the conveying platform 281, an adsorption platform 284 fixedly connected to the output end of the cylinder 283, an electric suction cup 285 fixedly installed on the adsorption platform 284, the adsorption end of the electric suction cup 285 being vertically downward and positioned below the adsorption platform 284.

[0031] Preferably, sliding rods 70 are vertically fixed at the four corners of the conveyor table 281, and the adsorption table 284 is slidably connected to the sliding rods 70. The bottom of the conveyor table 281 has a hole through which the electric suction cup 285 passes. The sliding rods 70 support and guide the adsorption table 284, improve the stability of the adsorption table 284 when it moves vertically, and prevent the adsorption table 284 from shaking violently when the rotating table 24 rotates, thereby affecting the conveying effect of the aluminum plate.

[0032] Preferably, the centering positioning stage 40 includes a positioning base 41, with both ends of the positioning base 41 fixedly connected to the input conveyor 30 and the slitting assembly 50, respectively. A positioning groove 42 is provided on the top of the positioning base 41, and a positioning seat 43 is fixedly provided at the bottom of the positioning groove 42. A third drive motor 44 is fixedly provided on the positioning seat 43, and a bidirectional threaded rod 45 is horizontally fixedly connected to the output end of the third drive motor 44. The end of the bidirectional threaded rod 45 away from the third drive motor 44 is rotatably connected to the positioning seat 43. The bidirectional threaded rod 45 is set in a direction perpendicular to the conveying direction of the aluminum plate. Centering components 46 are mirror-arranged on both sides of the bidirectional threaded rod 45 along the vertical center line, and the centering components 46 are partially arranged above the positioning groove 42.

[0033] Preferably, the centering component 46 includes a centering plate 461, which is threadedly connected to a bidirectional threaded rod 45. Several rotating rollers 462, which rotate around their own axis, are vertically arranged on one side of the centering plate 461 near the center of the bidirectional threaded rod 45. The two ends of the rotating rollers 462 are rotatably connected to the top and bottom of the centering plate 461, respectively. This arrangement ensures that the aluminum plate is in the center position when being cut, preventing the aluminum plate from shifting during movement and improving the cutting effect. On the other hand, during the movement of the aluminum plate, both sides are in contact with the rotating rollers 462, and the rotating rollers 462 rotate with the movement of the aluminum plate. The friction between the two is small, ensuring the centering effect without affecting the movement of the aluminum plate, resulting in high working efficiency.

[0034] Preferably, a support assembly 80 is provided on the positioning seat 43. The support assembly 80 includes a support plate 81, which is horizontally fixed on the positioning seat 43. A first rolling bearing 82 is symmetrically fixed on the support plate 81 along the vertical center line of the bidirectional threaded rod 45. The first rolling bearing 82 is fixedly sleeved on the bidirectional threaded rod 45 and is located between the two centering assemblies 46. The support assembly 80 plays a supporting and protective role for the bidirectional threaded rod 45. On the one hand, it can increase the stability of the bidirectional threaded rod 45 during operation and make the movement of the centering assembly 46 more stable. On the other hand, it can prevent the bidirectional threaded rod 45 from deforming after long-term use and improve the service life of the bidirectional threaded rod 45.

[0035] It should be noted that the bidirectional threaded rod 45 is a round rod-shaped structure with threads in opposite directions on the left and right sides along its vertical center line.

[0036] Preferably, the slitting assembly 50 includes a frame 51, with its two ends fixedly connected to a centering positioning table 40 and an output conveyor table 60, respectively. Two limiting rollers 52, which rotate around their own axes, are horizontally arranged on the frame 51. The two limiting rollers 52 are arranged vertically, with a gap between them that allows only the aluminum plate to pass through. The horizontal height of this gap is the same as the horizontal height of the aluminum plate when it passes through the centering positioning table 40. The setting direction of the limiting rollers 52 is perpendicular to the conveying direction of the aluminum plate. A cutting assembly 53 is provided on the frame 51. The cutting assembly 53 is used to cut the aluminum plate. The cutting assembly 53 is located on the side of the limiting rollers 52 away from the input conveyor table 30. The limiting rollers 52 play a limiting and supporting role, ensuring that the aluminum plate moves smoothly within the frame 51 and ensuring the cutting and slitting effect of the cutting assembly 53 on the aluminum plate.

[0037] Preferably, the cutting assembly 53 includes a positioning roller 531, which is horizontally fixed on the frame 51. A drive roller 532 driven by a motor is arranged parallel below the positioning roller 531. The drive roller 532 is rotatably connected to the frame 51. Several blade holders 533 are fixedly sleeved on the positioning roller 531. The blade holders 533 are sleeved on the drive roller 532 and connected to the drive roller 532 through a second rolling bearing 534. Annular blades 535 are provided on the blade holders 533 and are fixedly sleeved on the drive roller 532. This arrangement only requires one motor to drive the drive roller 532 to rotate synchronously and in the same direction, saving costs, providing good cutting results, and facilitating maintenance by staff.

[0038] Preferably, a support rod 90 is horizontally fixed on the frame 51. The support rod 90 is parallel to the positioning roller 531 and is positioned directly below the annular blade 535. The top height of the support rod 90 is flush with the gap height between the two limiting rollers 52. Several grooves 100 are formed on the top of the support rod 90. The position and number of the grooves 100 match the annular blade 535. The support rod 90 supports the aluminum plate inside the frame 51, improves the cutting effect of the aluminum plate, and avoids the situation of broken threads. The grooves 100 can ensure that the aluminum plate is cut fully while preventing the annular blade 535 from cutting the support rod 90, protecting the equipment and improving its service life. The support rod 90 is preferably a square rod structure to increase the contact area between the support rod 90 and the aluminum plate, resulting in a good supporting effect.

[0039] Preferably, both the input conveyor 30 and the output conveyor 60 are rotatably connected to a plurality of conveying rollers 110, the conveying rollers 110 being arranged in a direction perpendicular to the conveying direction of the aluminum plate, and the plurality of conveying rollers 110 being driven by a motor to rotate synchronously in the same direction.

[0040] All conveyor rollers 110 are equipped with sprockets at both ends. The sprockets on the same side of the conveyor rollers 110 are connected by a chain to achieve synchronous linkage. Any one conveyor roller 110 is driven to rotate by a motor installed on its side. Through the cooperation of the sprockets and the chain, all conveyor rollers 110 rotate synchronously in the same direction. This setting only requires one motor to drive all conveyor rollers 110 to rotate synchronously in the same direction, which saves costs and has a good conveying effect.

[0041] The working principle of this embodiment, and its more specific process, are as follows:

[0042] External transport equipment stacks and transports aluminum plates onto the retrieval platform 10. The second drive motor 26 on the rotating frame 25 starts, driving the lead screw 27 to rotate around its own axis. The lead screw 27 moves the conveyor platform 281 directly above the aluminum plates. The cylinder 283 on the conveyor platform 281 starts, driving the electric suction cup 285 vertically to the top of the aluminum plate stack via the suction platform 284. The electric suction cup 285 picks up the top aluminum plate. Then, the first drive motor 22 inside the base 21 starts... Machine 22 drives rotating column 23 to rotate around its own axis. Rotating column 23 drives rotating frame 25 to rotate via rotating table 24, realizing horizontal rotation during aluminum plate transportation. Then, second drive motor 26 drives lead screw 27 to rotate, thereby moving conveyor table 281 to directly above input conveyor table 30. Cylinder 283 drives electric suction cup 285 to move vertically onto input conveyor table 30 via suction table 284. Electric suction cup 285 smoothly lowers the aluminum plate. Then, the motor on input conveyor table 30 drives input conveyor table 3... All conveyor rollers 110 on the 0 rotate synchronously in the same direction, driving the aluminum plate to move towards the centering positioning platform 40. When the aluminum plate moves onto the positioning base 41, the third drive motor 44 starts, driving the bidirectional threaded rod 45 to rotate. The bidirectional threaded rod 45 drives the two centering plates 461 to move synchronously towards the aluminum plate. When the rotating rollers 462 on the two centering plates 461 contact the sidewalls of the aluminum plate, the third drive motor 44 stops, achieving the centering positioning of the aluminum plate. The aluminum plate continues to move under the action of the input conveyor 30. The aluminum sheet continues to move towards the slitting assembly 50, entering the frame 51. The aluminum sheet first passes through the gap between the two limiting rollers 52, and then moves onto the support rod 90. The motor drives the high-speed drive roller 532 to rotate, and the drive roller 532 drives all the annular blades 535 on it to rotate synchronously in the same direction. Several annular blades 535 cut the aluminum sheet into strips. The cut aluminum strips move to the output conveyor 60 under the action of the input conveyor 30, and then the output conveyor 60 drives the processed aluminum strips to move to the next processing area.

[0043] It should be noted that the horizontal length of the positioning base 41 and the frame 51 is less than the length in the direction of aluminum plate transportation, so as to ensure that the aluminum plate can be moved to the output conveyor 60 under the action of the input conveyor 30, and to ensure the continuity of aluminum plate transportation.

[0044] This utility model discloses an automatic feeding slitting machine. A feeding table 10 has a fixed feeding component 20 and an input conveyor 30 at one end. The feeding component 20 includes a base 21, a first drive motor 22 fixedly mounted inside the base 21, a rotating column 23 vertically mounted on the top of the base 21, and the output end of the first drive motor 22 fixedly connected to the rotating column 23. A rotating frame 25 is horizontally fixedly mounted on the top of the rotating column 23, and a second drive motor 26 is horizontally fixedly mounted on the rotating frame 25. A lead screw 27 is rotatably connected to the rotating frame 25, and the output end of the second drive motor 26 is fixedly connected to one end of the lead screw 27. A conveying component 28 is threadedly connected to the lead screw 27. This allows the automatic feeding slitting machine to freely select the feeding and discharging positions, enabling manufacturers to rationally arrange the production line layout according to their needs, saving production space. Furthermore, this slitting machine can automatically pick up and convey aluminum plates to be processed, improving the automation level of the production line, saving labor costs, and increasing work efficiency.
