Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] As Figures 1-5 shown, a shearing machine for the production of galvanized steel sheets includes a base 1. The upper surface of the base 1 is fixedly connected with a side frame 2. A limit groove 3 is provided on the inner wall of the side frame 2. A crankshaft 4 is rotatably connected to the inner wall of the side frame 2.

A first groove 8 is provided on the upper surface of the base 1. A rotating shaft is rotatably connected to the inner wall of the first groove 8. The number of the rotating shafts is two. One end of the rotating shaft penetrates through the inner wall of the first groove 8 and extends to the front of the base 1. A first motor is provided on the front of the base 1. The output end of the first motor is fixedly connected with the rotating shaft. One side of the outer surface of the rotating shaft is lapped with a conveyor belt 9;

[0024] In this embodiment, an annular groove 10 is provided on the upper surface of the base 1. A movable frame 11 is slidably connected to the inner wall of the annular groove 10. A collection box 12 is fixedly connected to the upper surface of the movable frame 11. A drive motor 13 is installed on the upper surface of the base 1. The output end of the drive motor 13 is fixedly connected with the movable frame 11. A second motor is provided on the front of the side frame 2. The output end of the second motor is fixedly connected with the crankshaft 4.

[0025] During specific use, when the second motor operates, its output drives the crankshaft 4 to rotate. When the crankshaft 4 rotates, it can perform a rotational movement with the I-shaped shaft 5 and drive the I-shaped shaft 5 to move. When the I-shaped shaft 5 moves on the crankshaft 4, it can perform a rotational movement with the fixed frame 6 and drive the fixed frame 6 to move up and down along the limit groove 3, and use the cutter 7 to cut the steel plate passing below the cutter 7. When the first motor operates, its output drives the rotating shaft to rotate and makes the conveyor belt 9 operate. The cut steel plate is conveyed by the conveyor belt 9 and falls into the collection box 12 on the movable frame 11. When the collection box 12 is full of the cut steel plates, the drive motor 13 operates and its output drives the movable frame 11 to rotate. At this time, the movable frame 11 performs a sliding movement with the annular groove 10, and drives another collection box 12 on the movable frame 11 to move to the position corresponding to the conveyor belt 9, which is convenient for collecting the cut steel plates and can also ensure the continuous operation of the equipment when taking the cut steel plates, thus ensuring the production efficiency.

[0026] In this embodiment, a second groove 14 is formed on the upper surface of the base 1. The inner wall of the second groove 14 is rotatably connected with a lower auxiliary roller 15. One end of the lower auxiliary roller 15 penetrates through the inner wall of the second groove 14 and extends to the front of the base 1. A third motor is installed on the front of the base 1, and the output end of the third motor is fixedly connected with the lower auxiliary roller 15.

[0027] During specific use, when the third motor operates, its output can drive the rotation of the lower auxiliary roller 15, and the lower auxiliary roller 15 can assist the passage of the uncut steel plate.

A piston rod 18 is provided at the output end of the cylinder 17. One end of the piston rod 18 penetrates through the upper surface of the mounting frame 16 and extends into the inner wall of the mounting frame 16. One end of the piston rod 18 is fixedly connected with a top frame 19. The inner side wall of the top frame 19 is rotatably connected with an upper auxiliary roller 20.

[0029] During specific use, when the cylinder 17 operates, it drives the movement of the piston rod 18, and the piston rod 18 drives the movement of the top frame 19, so that the upper auxiliary roller 20 of the top frame 19 contacts the steel plate passing through the lower auxiliary roller 15. When the lower auxiliary roller 15 rotates, it cooperates with the upper auxiliary roller 20 to facilitate the passage of the uncut steel plate.

[0030] In this embodiment, a square column 21 is slidably connected to the upper surface of the top frame 19. One end of the square column 21 penetrates through the upper surface of the top frame 19 and extends to the lower surface of the top frame 19. One end of the square column 21 is fixedly connected with a bottom plate 22. A sponge brush 23 is provided on the lower surface of the bottom plate 22. A tension spring 24 is fixedly connected to the upper surface of the top frame 19, and the tension spring 24 is fixedly connected with the square column 21.

[0031] During specific use, when the top frame 19 drives the upper auxiliary roller 20 to descend and contact the steel plate, the sponge brush 23 contacts the steel plate. The reaction force received from the steel plate causes the bottom plate 22 to drive the square column 21 to move upward. At this time, the tension spring 24 is in a stretched state and exerts a reaction force on the bottom plate 22, so that the sponge brush 23 is close to the steel plate, and the upper surface of the steel plate is cleaned by the sponge brush 23 when the steel plate passes through.

[0032] In this embodiment, a bidirectional screw 25 is rotatably connected to the inner surface of the top frame 19, and a chute 26 is formed on the upper surface of the top frame 19. The chute 26 penetrates the upper surface of the top frame 19 and extends to the lower surface of the top frame 19.

[0033] During specific use, the bidirectional screw 25 can rotate on the inner surface of the top frame 19 and perform a threaded movement with the connecting plate 28 when rotating.

[0034] In this embodiment, one end of the bidirectional screw 25 penetrates the inner surface of the top frame 19 and extends to the outer surface of the top frame 19, and a turntable 27 is fixedly connected to one end of the bidirectional screw 25.

[0035] During specific use, the bidirectional screw 25 can be conveniently rotated through the turntable 27.

[0036] In this embodiment, a connecting plate 28 is threadedly connected to one side of the outer surface of the bidirectional screw 25. The connecting plate 28 is slidably connected to the chute 26, and a roller 29 is rotatably connected to the inner surface of the connecting plate 28.

[0037] During specific use, when the bidirectional screw 25 rotates, it can perform a threaded movement with the two connecting plates 28 to drive the two connecting plates 28 to approach and limit the steel plate. The roller 29 rolls when the steel plate passes through.

[0038] Working principle: During use, when the second motor operates, its output drives the crankshaft 4 to rotate. When the crankshaft 4 rotates, it can perform rotational motion with the I-shaped shaft 5 and drive the I-shaped shaft 5 to move. When the I-shaped shaft 5 moves on the crankshaft 4, it can perform rotational motion with the fixed frame 6 and drive the fixed frame 6 to move up and down along the limit groove 3, and use the cutter 7 to cut the steel plate passing below the cutter 7. When the first motor operates, its output drives the rotating shaft to rotate and makes the conveyor belt 9 operate. The cut steel plate is conveyed by the conveyor belt 9 and falls into the collection box 12 on the movable frame 11. When the collection box 12 is full of the cut steel plates, the drive motor 13 operates and its output drives the movable frame 11 to rotate. At this time, the movable frame 11 makes a sliding motion with the annular groove 10, and drives another collection box 12 on the movable frame 11 to move to the position corresponding to the conveyor belt 9, which is convenient for collecting the cut steel plates and can also ensure the continuous operation of the equipment when taking the cut steel plates, ensuring production efficiency. After the uncut galvanized steel plate passes through the lower auxiliary roller 15, the cylinder 17 operates and drives the top frame 19 to move down through the piston rod 18, so that the upper auxiliary roller 20 contacts the galvanized steel plate. At this time, the top frame 19 drives the bottom plate 22 at the lower end of the square column 21 and the sponge brush 23 to contact the upper surface of the galvanized steel plate. The square column 21 moves up, and at this time the tension spring 24 is in a stretched state, making the sponge brush 23 close to the upper surface of the steel plate. When the bidirectional screw 25 rotates, it performs threaded motion with the two connecting plates 28 and drives the two connecting plates 28 to approach each other to limit the steel plate. When the third motor operates, its output drives the lower auxiliary roller 15 to rotate, and makes the limited steel plate pass through. At this time, the upper auxiliary roller 20 rotates, and the roller 29 on the inner surface of the connecting plate 28 rotates, ensuring that the steel plate can pass through and be correspondingly collected into the collection box 12 after cutting, and the sponge brush 23 can wipe the upper surface of the steel plate to prevent impurities from affecting the cutting quality during cutting.
