Detailed Embodiments

[0016] The following further describes the detailed embodiments of the present utility model with reference to the drawings.

[0017] As Figures 1-4As shown in the figure, an elevator sheet cutting device includes an installation table 2. A first conveyor roller section 3 and a second conveyor roller section 4 are arranged on the installation table 2. There is a gap between the first conveyor roller section 3 and the second conveyor roller section 4. Slide rails 5 are respectively arranged on both sides of the upper surface of the installation table 2. It also includes an installation groove 6. Support legs 7 that cooperate with the slide rails 5 are respectively arranged at both ends of the installation groove 6. A lead screw 8 is rotatably connected inside the installation groove 6. A slider 9 is slidably connected inside the installation groove 6. The slider 9 is threadedly connected to the lead screw 8. An installation plate 10 is arranged on the upper surface of the slider 9. A laser cutter 11 is arranged at the lower end of the installation groove 6. The installation plate 10 and the laser cutter 11 are connected through an intermediate member 12. Shells 13 are respectively arranged at both ends of the installation groove 6. First gears 14 are respectively arranged at both ends of the lead screw 8. The first gears 14 are located inside the shells 13. A bent plate 15 is arranged on one side of the support leg 7. A rotating shaft 16 is arranged on the bent plate 15. A second gear 17 that meshes with the first gear 14 is arranged at one end of the rotating shaft 16. A third gear 18 is arranged at the other end of the rotating shaft 16. A straight rack 19 that meshes with the third gear 18 is arranged on the installation table 2. The straight rack 19 and the slide rails 5 are respectively located on both sides of the installation table 2. A first motor 20 for driving the lead screw 8 to rotate is arranged on the outer surface of one of the shells 13.

[0018] A unwinding device is arranged at one end of the cutting device. The metal coil 1 is located on the unwinding device. The unwinding of the coil 1 is realized through the unwinding device. After the coil 1 passes through the anti-rolling process, it first passes through the first conveyor roller section 3. The first conveyor roller section 3 has its own power and can assist the movement of the coil 1 placed on the first conveyor roller section 3. After the coil 1 passes through the first conveyor roller section 3, it will enter the area between the first conveyor roller section 3 and the second conveyor roller section 4. In this area, the segmented cutting of the coil 1 is realized. The second conveyor roller section 4 also has its own power. The cut coil 1 is transported out by the second conveyor roller section 4.

[0019] When cutting the continuously moving coil 1, first start the first motor 20. The first motor 20 drives the lead screw 8 and the first gears 14 at both ends of the lead screw 8 to rotate. The first gears 14 drive the rotating shaft 16 and the third gear 18 on the rotating shaft 16 to rotate through meshing with the second gears 17. The third gear 18 drives the movement of the bent plate 15 through meshing with the straight rack 19. The support leg 7 is driven to move in the slide rail 5 through the bent plate 15, and then the installation groove 6 and the laser cutter 11 on the installation groove 6 are driven to move. The moving direction and speed of the installation groove 6 are the same as those of the coil 1. During the rotation of the lead screw 8, the mounting plate 10 is driven to move linearly along the lead screw 8 through cooperation with the slider 9. When the mounting plate 10 moves, it will drive the laser cutter 11 to move linearly along the lead screw 8, so that the laser cutter 11 can cut the coil 1 into rectangular plates. Since the length of the cut plate is relatively long and its front end has entered the second conveyor roller section 4, the second conveyor roller section 4 can transfer the cut plate out. When cutting the coil 1 next time, control the first motor 20 to rotate in the reverse direction to make the laser cutter 11 and the installation groove 6 return to their original positions. During the process of the laser cutter 11 returning to its original position, it does not cut the coil 1, and during the return process, the next cutting position of the coil 1 has not reached the predetermined position. When the coil 1 reaches the cutting position, the first motor 20 is started, and the coil 1 is continuously cut through the movement of the installation groove 6 and the laser cutter 11.

[0020] Further, an extrusion conveyor part is arranged on the first conveyor roller section 3. The extrusion conveyor part includes a cover shell 21 arranged on the upper surface of the installation table 2. A main shaft 22 is arranged inside the cover shell 21. A second motor 23 for controlling the rotation of the main shaft 22 is arranged on the outer surface of the cover shell 21. An extrusion wheel 24 is rotatably connected to the main shaft 22. When conveying the coil 1, start the second motor 23. The second motor 23 drives the main shaft 22 to rotate, and the main shaft 22 drives the extrusion wheel 24 to rotate. The coil 1 is located between the extrusion wheel 24 and the first conveyor roller section 3 and is extruded. Therefore, through the rotation of the extrusion wheel 24, the unwinding part of the coil 1 can be stably moved, and the part after the coil 1 is unwound is restricted, improving the movement stability of the coil 1.

[0021] Further, two rollers 25 are symmetrically arranged on the mounting plate 10. The two rollers 25 are respectively located on both sides of the slider 9. The rollers 25 can roll along the inner side wall of the installation groove 6. Through the rollers 25, a certain interval can be reserved between the mounting plate 10 and the upper surface of the installation groove 6 to reduce the frictional resistance when the mounting plate 10 moves in the installation groove 6, and the mounting plate 10 is supported by the rollers 25 to improve the movement stability of the mounting plate 10.

[0022] Further, the surface of the support leg 7 is hollowed out to save materials, and lubricating oil can be sprayed onto the meshing part of the first gear 14 and the second gear 17 through the hollowed-out part of the support leg 7.

[0023] Further, extension plates 26 are provided at both ends of the mounting groove 6 to increase the connection area between the housing 13 and the mounting groove 6, improve the mounting stability of the housing 13, and facilitate the protection of the first gear 14 inside the housing 13.

[0024] Since the metal coil 1 is relatively heavy as a whole, the motor load on the unwinding mechanism is also relatively large. When controlling the unwinding of the metal coil 1, the repeated start and stop of the motor will have an adverse effect on its service life. When this cutting device is in use, by controlling the movement of the laser cutter 11, the continuously moving coil 1 can be cut, so that the motor on the unwinding mechanism does not need to start and stop repeatedly, which is beneficial to extending its service life. Moreover, the first motor 20 that provides the power source for the movement of the laser cutter 11 has a relatively small load, and the repeated start and stop has a relatively small impact on it, and the maintenance cost is also lower, having good economy.
