[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0019] See also Figures 1 to 3 The worm gear 25 is meshed with the worm gear 26 at the bottom and meshed with the third motor 24 at the bottom. One end of the worm gear 25 is fixedly connected to the worm gear 26, and the other end of the worm gear 25 is fixedly connected to the third motor 24. A third positioning plate 23 is fixedly connected to the front and rear sides of one end of the upper surface of the base plate 1.
[0020] In this embodiment: when adjusting the width of the upper surface of the pushing roller 28, the first motor 17 is started, and the first motor 17 drives the bidirectional screw 6 fixedly connected to the output end to rotate. Since the threads on the outer surfaces of the front and rear sides of the rotating bidirectional screw 6 are opposite, the corresponding connected slider 3 is pushed to slide in the direction of the middle of the slide groove 2, thereby driving the support plate 4 fixedly connected to the top of the slider 3 to slide in the middle direction above the slide groove 2. During the sliding process of the support plate 4, the guide splint 27 fixedly connected at one end thereof will slide in the direction of the middle of the pushing roller 28 under the drive of the support plate 4. At the same time, the support plate 4 will drive the lifting slide 13 slidingly engaged with the lifting slide cavity 5 inside the lifting slide cavity 5 to move in the direction of the middle of the upper roller 12 during the sliding process. When the spacing between a group of guide clamps 27 matches the width of the steel plate to be pushed, the power supply of the first motor 17 is disconnected. At this time, the spacing between a group of support plates 4 matches the width of the steel plate. When the steel plate is pushed, the guide clamps 27 provided on the front and rear sides of the pushing roller 28 limit the front and rear sides of the pushed steel plate to prevent the moving trajectory of the steel plate from deviating.
[0021] When pushing the steel plate, the third motor 24 is started, and the third motor 24 drives the worm 25 fixedly connected to the output end to rotate. The rotating worm 25 drives the multiple sets of worm gears 26 meshingly connected above to rotate. The rotating worm gears 26 drive the pushing roller 28 correspondingly connected on one side to rotate. The rotating pushing roller 28 pushes the steel plate placed above to move onto the lower rolling roller 11, completing the pushing of the steel plate.
[0022] Please refer to Figure 1 and Figure 2 A lifting slide cavity 5 is provided in the middle of the inner side of the support plate 4, and a lower roller 11 is slidably connected to the lower side of the inner side of the lifting slide cavity 5, and a lifting slide 13 is slidably connected to the upper side of the inner side of the lifting slide cavity 5. The middle part of the lifting slide 13 is slidably connected to the upper roller 12. A measuring scale line is provided on the outer surface of one end of one side of the support plate 4, and a scale pointer 14 is fixedly connected to the lower side of one end of the lifting slide 13. A slide rod 8 is fixedly connected to the left and right ends of the upper surface of the lifting slide 13, and the top of the slide rod 8 is fixedly connected to the limiting slide 9. An electric telescopic rod 7 is provided in the middle of the rear side of the top of the support plate 4, and the top of the electric telescopic rod 7 is fixedly connected to the middle of the lower surface of the limiting slide 9. The inner walls of the left and right ends of the limiting slide 9 are respectively slidably connected to the outer walls of the left and right ends of the upper outside of the support plate 4, and a camera 15 is provided at one end of one side of the limiting slide 9.
[0023] When the upper roller 12 and the lower roller 11 are adjusted, the electric telescopic rod 7 drives the limit slide 9 fixed at the top to slide downward along the upper side of the outer side of the support plate 4, thereby driving the slide bars 8 fixed at the left and right ends of the lower surface of the limit slide 9 to slide downward, and the sliding bar 8 that descends will drive the lifting slide 13 fixed at the bottom to slide downward along the lifting slide cavity 1 5, and the scale pointer 14 fixed at the bottom end of one side of the sliding lifting slide 13 will slide downward along the measuring scale line. When the camera 15 captures the scale pointer 14 on the lifting slide 13 slidingly connected to the inner side of the opposite support plate 4 sliding to the specified scale line, the electric telescopic rod 7 stops descending. At this time, the upper roller 12 rotating on the inner side of the lifting slide 13 will hover at a specified height above the lower roller 11. When the upper roller 12 descends, the bevel gear 21 at one end thereof will slide downward along the lifting slide cavity 29 opened in the middle part of the inner side of the second positioning plate 18, thereby improving the stability of the upper roller 12 sliding up and down.
[0024] Please refer to Figure 1 、 Figure 2 and Figure 3The upper roller 12 and the lower roller 11 are both fixedly connected to a bevel gear 21 in the middle of the front side. The bevel gear 21 provided on the front side of the upper roller 12 is meshed with a bevel gear 20 at the bottom. A rotating rod 19 is provided in the middle part of the inner side of the bevel gear 20. The bottom of the rotating rod 19 is rotatably connected to one side of the upper surface of the base plate 1. One end of the rotating rod 19 is provided with a first positioning plate 16. The top of one end of the first positioning plate 16 is rotatably connected to the top of the rotating rod 19. A second positioning plate 18 is provided on the rear side of the rotating rod 19. The bottom of the second positioning plate 18 is fixedly connected to the top of the base plate 1. The top of the rotating rod 19 is fixedly connected to the second motor 22. The second motor 22 is located at one end of the top of the first positioning plate 16. A lifting slide cavity 29 is provided above the middle part of the inner side of the second positioning plate 18. The outer side of the bevel gear 21 is slidably connected to the inner side of the lifting slide cavity 29.
[0025] In this embodiment, when the upper roller 12 slides up and down, the bevel gear 21 fixedly connected to one side drives the bevel gear 1 20 meshing with the bevel gear 21 to slide downward along the cross clamp provided above the rotating rod 19, which helps to prevent the bevel gear 1 20 from affecting the downward trend of the bevel gear 21. An L-shaped support block is provided below the bevel gear 1 20, and the upper part of one side of the L-shaped support block is rotatably connected to the rear side of the bevel gear 2 21.
[0026] When metal is rolled, the second motor 22 is started, and the second motor 22 drives the rotating rod 19 fixedly connected to the output end to rotate, thereby driving the bevel gear 1 20 clamped on the outer side above the rotating rod 19 to rotate, and the rotating bevel gear 1 20 will drive the corresponding meshing connected bevel gear 2 21 on one side to rotate, and the rotating bevel gear 2 21 will drive the corresponding upper roller 12 on one side to rotate, and at the same time, the rotating rotating rod 19 will drive the meshing connected lower roller 11 on the lower side to rotate, and the rotating upper roller 12 and lower roller 11 will roll the metal plate moved to the bottom of the upper roller 12.
[0027] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
