[0018] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations. Example 1

A heating mechanism 5 is provided on the left first mounting block 206 and the left second mounting block 207, and the heating mechanism 5 is used to heat the rolling mechanism 3. A water cooling mechanism 6 is installed on the outer side of the right first mounting block 206 and the right second mounting block 207, and the water cooling mechanism 6 is used to cool the rolling mechanism 3. The interior of the first movable plate 204 and the second movable plate 205 is connected to the first mounting block 206 through a lifting mechanism 4, and the lifting mechanism 4 is used to lift the upper rolling roller. Two sets of clamping mechanisms 7 are provided on the second movable plate 205, and a roller changing mechanism 8 is installed on the rear side of the top end of the bottom plate 1, and the roller changing mechanism 8 is used to replace the damaged roller 301. Example 2

[0020] Please refer to Figure 2 and Figure 3 As shown, the mounting mechanism 2 further includes a first screw 201, which is rotatably connected to the inside of the two sets of fixed plates 101, and a first fixed rod 202 is fixedly connected between the two sets of fixed plates 101. The threads at both ends of the first screw 201 are in opposite directions, and a first movable plate 204 and a second movable plate 205 are respectively threadedly connected to both ends of the outer surface of the first screw 201, and the first movable plate 204 and the second movable plate 205 are slidably connected to the first fixed rod 202. A first servo motor is arranged on the outer side of one set of fixed plates 101. Machine 203, one end of the first screw 201 is fixedly mounted on the output end of the first servo motor 203, the inner sides of the first mounting block 206 and the second mounting block 207 are rotatably connected with a rotating disk 208, a double-headed cylinder 209 is arranged inside the rotating disk 208, both output ends of the double-headed cylinder 209 are fixedly mounted with a first clamping member 210, the outer sides of the left first mounting block 206 and the left second mounting block 207 are both mounted with a first driving motor 211, and the output end of the first driving motor 211 is fixedly connected to the left rotating disk 208.

[0021] It can be understood by those skilled in the art that the first screw 201 is driven to rotate by the output end of the first servo motor 203, so that the first movable plate 204 and the second movable plate 205 are brought closer to or farther from each other, so that the first mounting blocks 206 and the second mounting blocks 207 on both sides are brought closer to or farther from each other; and when approaching, the spacing between the first mounting blocks 206 and the second mounting blocks 207 on both sides is adapted to the length of the upper roller and the lower roller, and then both output ends of the double-headed cylinder 209 are extended, so that the two groups of first clamping members 210 abut against the inner walls of the rollers 301 at both ends of the upper roller and the lower roller to achieve fixation; the left rotating disk 208 is driven to rotate by the output end of the first drive motor 211 to drive the upper roller and the lower roller to rotate. During metal rolling, the rotation directions of the output ends of the two groups of first drive motors 211 in the present invention are opposite, thereby achieving rolling of metal materials. Example 3

[0022] Please refer to Figure 4 As shown, the lifting mechanism 4 includes a first screw rod 401 and a first connecting rod 402, the first movable plate 204 and the second movable plate 205 are both rotatably connected to the first screw rod 401, the first connecting rod 402 is fixedly connected to the inside of the first movable plate 204 and the second movable plate 205, the first mounting block 206 is threadedly connected to the first screw rod 401, the first mounting block 206 is slidably connected to the first connecting rod 402, and the top of the first movable plate 204 and the second movable plate 205 are both installed with a first stepper motor 403, and the top of the first screw rod 401 is fixedly connected to the output end of the first stepper motor 403.

[0023] It can be understood by those skilled in the art that by starting the first stepper motors 403 on both sides, the output end of the first stepper motor 403 drives the first screw rod 401 to rotate, so that the first mounting blocks 206 on both sides slide up and down synchronously along the outer surface of the first connecting rod 402. On the one hand, the metal plate can be pressed into different thicknesses according to the needs of real life, and on the other hand, the height of the upper roller can be changed. Example 4

[0024] Please refer to Figure 5 As shown, the heating mechanism 5 includes a second drive motor 501, and the second drive motor 501 is installed on the top of the first mounting block 206 on the left and the bottom of the second mounting block 207 on the left. The output end of the second drive motor 501 is fixedly connected with a driving tooth 502, and the first mounting block 206 on the left and the second mounting block 207 on the left are rotatably connected with a rotating rod 503, and the outer surface of the rotating rod 503 is fixedly installed with a driven tooth 504 meshing with the driving tooth 502, and the outer end of the rotating rod 503 is fixedly connected with a mounting member 505, and the internal thread of the mounting member 505 is connected to the heating tube 506.

[0025] It can be understood by those skilled in the art that in real life, metal rolling is divided into hot rolling situations, and the hot metal plate passes between the upper roller and the lower roller. In order not to change the material properties of the metal itself, it is necessary to prevent the heat on the hot metal plate from disappearing. Therefore, the present invention introduces a heating tube 506, and two groups of heating tubes 506 heat the upper roller and the lower roller respectively, and the upper roller and the lower roller are in a rotating state, so the upper roller and the lower roller can be well heated evenly; the output end of the second driving motor 501 drives the driving tooth 502 to rotate, and then the driven tooth 504 and the rotating rod 503 rotate as a whole, driving the heating tube 506 to rotate; since the mounting member 505 and the heating tube 506 are threadedly connected, the heating tube 506 can also be quickly replaced. Example 5

[0026] Please refer to Figure 6 , Figure 7 and Figure 8 As shown, the water cooling mechanism 6 includes a fixed cylinder 601, the outer sides of the first right mounting block 206 and the second right mounting block 207 are both connected with the fixed cylinder 601, the interior of the fixed cylinder 601 is provided with a first telescopic cylinder 602, a second telescopic cylinder 603 and a third telescopic cylinder 604, a fixing part 605 is welded inside the fixed cylinder 601, a second screw rod 606 is rotatably connected inside the fixing part 605, a second stepping motor 607 is arranged on the inner wall of the fixed cylinder 601, the other end of the second screw rod 606 is fixedly connected to the output end of the second stepping motor 607, and the outer surface of the second screw rod 606 is threadedly connected with a moving part 608.

[0027] Please refer to Figure 7 As shown, the interior of the fixed cylinder 601 is rotatably connected to the first connecting arm 609 and the second connecting arm 610, the interior of the third telescopic cylinder 604 is rotatably connected to the third connecting arm 611 and the fourth connecting arm 612, the other ends of the first connecting arm 609 and the second connecting arm 610 are rotatably connected to the scissor-type telescopic member 613, and the other two ends of the scissor-type telescopic member 613 are rotatably connected to the third connecting arm 611 and the fourth connecting arm 612 respectively, the interiors of the first telescopic cylinder 602 and the second telescopic cylinder 603 are both provided with a sliding groove 615, and the scissor-type telescopic member 613 is provided with a sliding rod 614 adapted to the sliding groove 615, the sliding rod 614 is slidably connected to the sliding groove 615, and the scissor-type telescopic member 613 is connected to the movable member 608.

[0028] Please refer to Figure 6As shown, a connecting frame 616 is fixedly installed on the outer end of the third telescopic cylinder 604, and a second screw 617 is rotatably connected in the connecting frame 616. The threads at both ends of the second screw 617 have opposite rotation directions. A second fixing rod 618 is also installed in the connecting frame 616, and two groups of second clamping members 620 are slidably connected to the second fixing rod 618.

A second servo motor 619 is installed on the outside of the connecting frame 616, and one end of the second screw 617 is fixedly connected to the output end of the second servo motor 619. The second clamping member 620 is used to clamp the U-shaped tube 621.

[0029] It can be understood by those skilled in the art that in real life, metal rolling is also divided into cold rolling. Therefore, the present invention introduces a U-shaped tube 621. The two ends of the outer part of the U-shaped tube 621 are connected to an external hose (the hose is not drawn in the present invention). The U-shaped tube 621 is filled with cooling water. The U-shaped tube 621 has a large area, which improves the cooling effect. The second screw 617 is driven to rotate by the output end of the second servo motor 619, so that the two groups of second clamping members 620 are close to or away from each other. When they are close, the U-shaped tube 621 is clamped, and when they are away from each other, the U-shaped tube 621 is released. The second screw 606 is driven to rotate by the output end of the second stepper motor 607, so that the moving member 608 reciprocates, driving the scissor-type telescopic member 613 to be in an extended or retracted state. When extended, The first telescopic cylinder 602, the second telescopic cylinder 603 and the third telescopic cylinder 604 are driven to slide out of the interior of the fixed cylinder 601, so that the U-shaped tube 621 is automatically taken out from the interior of the upper roller and the lower roller. When retracting, the first telescopic cylinder 602, the second telescopic cylinder 603 and the third telescopic cylinder 604 are driven to retract into the interior of the fixed cylinder 601, so that the U-shaped tube 621 is installed in the interior of the upper roller and the lower roller. The cooperation of the slide rod 614 and the slide groove 615 improves the movement stability of the scissor-type telescopic member 613. The present invention designs a water cooling mechanism 6, which is used during cold rolling on the one hand, and on the other hand, at the end of hot rolling, since the temperature of the upper roller and the lower roller is relatively high, in order to avoid the risk of scalding of the staff, the upper roller and the lower roller can also be cooled by water cooling. Example 6

[0030] Please refer to Figure 7As shown, the clamping mechanism 7 includes a rotating cylinder 701, a third screw rod 703 and a movable frame 706. Two groups of rotating cylinders 701 are rotatably connected inside the second movable plate 205. A third driving motor 702 for driving the rotating cylinder 701 to rotate is also installed in the second movable plate 205. The third screw rod 703 is rotatably connected to the inside of the rotating cylinder 701. The movable frame 706 is threadedly connected to the third screw rod 703. One end of the third screw rod 703 is fixedly installed on the output end of the third stepping motor 705. The third stepping motor 705 is arranged on the outside of the rotating cylinder 701. The movable frame 706 is slidably connected to the third connecting rod. On the connecting rod 704, the third connecting rod 704 is welded in the rotating cylinder 701, and the third screw rod 707 is rotatably connected in the movable frame 706. The third servo motor 709 is installed on the outside of the movable frame 706. The output end of the third servo motor 709 extends into the movable frame 706 and is fixedly connected to one end of the third screw rod 707. The threads at both ends of the third screw rod 707 have opposite rotation directions, and both ends of the outer surface of the third screw rod 707 are threadedly connected with a third clamping member 710. A third fixed rod 708 is also connected in the movable frame 706, and the third clamping member 710 is slidably connected to the third fixed rod 708.

[0031] It can be understood by those skilled in the art that, during metal rolling, in order not to affect the feeding of the metal, the rotating cylinder 701 needs to be rotated to an outward position, so the present invention provides a third driving motor 702; the third screw rod 703 is driven to rotate by the output end of the third stepper motor 705, so that the movable frame 706 slides back and forth along the outer surface of the third connecting rod 704; the third screw rod 707 is driven to rotate by the output end of the third servo motor 709, so that the two groups of third clamping members 710 are moved closer to or away from each other.

[0035] Working principle and use process of this device: In order to clearly describe the roller changing principle of the present invention, we use Figure 1 and Fig.14 For the sake of perspective, in real life, the upper roller and the lower roller are both integral roller-shaped cylinders. When a certain part is damaged, it is necessary to completely replace the entire roller. In the present invention, the upper roller and the lower roller are composed of a plurality of groups of rollers 301 threadedly connected. Therefore, when a certain part is damaged, it is sufficient to replace the corresponding roller 301. We name the rollers 301 in the upper roller and the lower roller by position. The rollers 301 at the two end positions are D-1 and D-2, and the roller 301 between D-1 and D-2 is named D-3. When the roller 301 at D-1 is replaced, the U-shaped tube 621 is pulled out to the outside of the upper roller and the lower roller, and the two output ends of the double-headed cylinder 209 on the left are retracted, driving the first clamping member 210 not to abut against the inner wall of the roller 301 at D-1, and the first screw 201 is driven to rotate by the output end of the first servo motor 203, so that the first movable plate 204 and the second movable plate 205 are separated from each other, while the upper roller and the lower roller are still in a clamped state as a whole, and the second drive The output end of the stepping motor 501 drives the heating tube 506 to rotate to a position where the roller changing operation is not affected. The fourth stepping motor 804, the fifth stepping motor 808 and the electric push rod 810 are used in coordination, so that the mounting plate 812 moves to the position of the roller 301 at D-1, and the roller 301 at D-1 is inside the mounting plate 812. The fourth clamping member 819 clamps the outer wall of the roller 301 at D-1, and the output end of the third driving motor 702 drives the heating tube 506 to rotate to a position where the roller changing operation is not affected. The fourth stepping motor 804, the fifth stepping motor 808 and the electric push rod 810 are used in coordination, so that the mounting plate 812 moves to the position of the roller 301 at D-1, and the roller 301 at D-1 is inside the mounting plate 812. The fourth clamping member 819 clamps the outer wall of the roller 301 at D-1. The rotating drum 701 rotates to a horizontal position, and under the action of the output end of the third stepper motor 705, the two sets of third clamping members 710 move to the roller 301 adjacent to the right side of the D-1 roller 301, and then under the action of the output end of the third servo motor 709, the two sets of third clamping members 710 are moved closer to each other to clamp the roller 301, and then under the cooperation of the fifth stepper motor 808 and the fourth drive motor 814, the roller 301 at D-1 is driven to rotate and move to the left side. The roller 301 at D-1 is removed by the fourth stepper motor 804, the fifth stepper motor 808 and the electric push rod 810, and the mounting plate 812 returns to the initial position. The external manipulator places the new roller 301 inside the mounting plate 812, and the fourth clamping member 819 clamps the outer wall of the new roller 301. The above operation is repeated, so that the new roller 301 rotates and moves to the right, so that the new roller 301 is installed at D-1. When replacing the roller 301 at D-2, the U-shaped tube 621 is pulled out to the outside of the upper roller and the lower roller, and the two output ends of the double-headed cylinder 209 on the right side are retracted, driving the first clamping member 210 not to abut against the inner wall of the roller 301 at D-2, and the first screw 201 is driven to rotate by the output end of the first servo motor 203, so that the first movable plate 204 and the second movable plate 205 are separated from each other, while the upper roller and the lower roller are still in a clamped state as a whole, and the same replacement method of the roller 301 at D-1 can be adopted; When a roller 301 at D-3 is replaced, the U-shaped tube 621 is pulled out to the outside of the upper roller and the lower roller, and the two output ends of the double-headed cylinder 209 on the right are retracted, driving the first clamping member 210 not to abut against the inner wall of the roller 301 at D-2, and the first screw 201 is driven to rotate through the output end of the first servo motor 203, so that the first movable plate 204 and the second movable plate 205 are separated from each other, while the upper roller and the lower roller are still in a clamped state as a whole. In order to describe the replacement principle more clearly, it is assumed that Fig.14 The roller 301 marked with D-3 needs to be replaced. First, under the action of the output end of the third stepper motor 705, the two groups of third clamping members 710 move to the roller 301 adjacent to the left side of the D-3 roller 301, and then under the action of the output end of the third servo motor 709, the two groups of third clamping members 710 are moved close to each other to clamp the roller 301. Under the cooperation of the fifth stepper motor 808 and the fourth drive motor 814, the roller 301 at D-3 is driven to rotate and move to the right side, so that the roller 301 at D-3 and the roller 301 on its right side are completely removed. That is, Fig.14 The four rollers 301 shown in the figure are then driven to move to the right, and the four rollers 301 are clamped as a whole by the double-headed cylinder 209 on the right. Then, under the cooperation of the third stepper motor 705 and the third servo motor 709, the roller 301 on the right side adjacent to the roller 301 at D-3 is clamped, and then under the cooperation of the fifth stepper motor 808 and the fourth drive motor 814, the roller 301 at D-3 is driven to rotate and move to the left side, thereby realizing the Fig.14 The marked D-3 roller 301 is removed, and then the mounting plate 812 returns to its initial position. The external manipulator places the new roller 301 inside the mounting plate 812, and the fourth clamping member 819 clamps the outer wall of the new roller 301. The opposite operation of removing the D-3 roller 301 is performed to install the new roller 301 at the D-3 position, and form new upper and lower rollers. This is convenient and fast, and the entire process is automated, meeting the needs of the staff.
