[0023] The specific implementation of the present invention is further described below in conjunction with the accompanying drawings. Example 1

[0024] like Figure 1 The corrugated plate rolling machine shown in the figure comprises a main roller 1, an auxiliary roller 4, a front roller 5, a rear roller 7, a laser photoelectric switch 8 and a length measuring wheel 9, wherein the main roller 1 is driven to rotate by a main roller servo drive device 3 electrically connected to a motion controller 2, as shown in FIG. Figure 2 As shown, the main roller servo drive device 3 in this embodiment includes a main roller servo driver 29 and a main roller servo motor 30. The main roller servo driver 29 is electrically connected to the motion controller 2, and the main roller servo motor 30 is electrically connected to the main roller servo driver 29. The main roller 1 is mechanically connected to the output shaft of the main roller servo motor 30. The auxiliary roller 4 is located directly below the main roller 1 and is parallel to the main roller 1. The center line of the auxiliary roller 4 and the center line of the main roller 1 are located on the same vertical plane. The auxiliary roller 4 is driven to move vertically by an auxiliary roller lifting drive device electrically connected to the motion controller 2. The vertical movement of the auxiliary roller 4 is used to adjust the distance between the main roller 1 and the auxiliary roller 4. When the auxiliary roller 4 moves downward, the distance between the auxiliary roller 4 and the main roller 1 is increased. At this time, the plate 6 can be placed on the auxiliary roller 4, and after the plate 6 is rolled, the corrugated roll can be easily unloaded. The auxiliary roller 4 is also driven to rotate by the auxiliary roller servo drive device 31 electrically connected to the motion controller 2, and is used to convey the plate 6 when in use. Figure 2As shown, the auxiliary roller servo drive device 31 in this embodiment includes an auxiliary roller servo driver 32 and an auxiliary roller servo motor 33. The auxiliary roller servo driver 32 is electrically connected to the motion controller 2, the auxiliary roller servo motor 33 is electrically connected to the auxiliary roller servo driver 32, and the auxiliary roller 4 is mechanically connected to the output shaft of the auxiliary roller servo motor 33. In the present invention, the auxiliary roller 4 and the main roller 1 have the same rotational linear speed and opposite directions, and are used to convey the plate 6 clamped between the main roller 1 and the auxiliary roller 4 forward when in use. The auxiliary roller 4 and the main roller 1 have the same linear speed. According to the diameters of the main roller 1 and the auxiliary roller 4, the rotational angular velocities of the two are determined to achieve matching of the rotational speeds of the auxiliary roller 4 and the main roller 1, and jointly drive the plate 6 to move.

[0025] like Figure 1 As shown, the front roller 5 in the present invention is located in front of the auxiliary roller 4 and parallel to the auxiliary roller 4, the front roller 5 is driven to move vertically by a front roller lifting drive device electrically connected to the motion controller 2, and the front roller 5 moves upward to bend the plate 6 upward from the front of the main roller 1, the rear roller 7 is located behind the auxiliary roller 4 and parallel to the auxiliary roller 4, the rear roller 7 is driven to move vertically by a rear roller lifting drive device electrically connected to the motion controller 2, and the rear roller 7 moves upward to bend the plate 6 upward from the rear of the main roller 1, and the plate 6 is bent upward by the front roller 5 and the rear roller 7 on both sides of the auxiliary roller 4, so that the plate 6 is arc-shaped, thereby achieving the purpose of rolling the plate.

[0026] like Figure 1 As shown, the laser photoelectric switch 8 in the present invention is electrically connected to the motion controller 2 and is located in front of the main roller 1. When the present invention is in use, when the auxiliary roller 4 moves upward until the upper surface and the lower surface of the plate 6 contact the main roller 1 and the auxiliary roller 4 respectively, the height of the plate 6 is equal to that of the laser photoelectric switch 8. The laser photoelectric switch 8 is used to mark the position of the plate 6 when the plate 6 hits the laser photoelectric switch 8 as a reference position. When the plate 6 is transported to its end and reaches the laser photoelectric switch 8, and blocks the light beam of the laser photoelectric switch 8, a signal is sent to the motion controller 2, and the main roller 1 and the auxiliary roller 4 stop transporting the plate 6 forward. like Figure 2 As shown, the measuring wheel 9 in the present invention is located behind the main roller 1 and is electrically connected to the motion controller 2, and is used to measure the distance moved by the plate 6 after marking the reference position and feed back to the motion controller 2. The motion controller 2 controls the rotation of the main roller 1 and the auxiliary roller 4 according to the distance, thereby realizing closed-loop control of the moving distance position of the plate 6.

[0027] like Figure 2As shown, the auxiliary roller lifting drive device in the present invention includes an auxiliary roller left hydraulic cylinder 10 and an auxiliary roller right hydraulic cylinder 11 respectively connected to the left end and the right end of the auxiliary roller 4, and the piston rods of the auxiliary roller left hydraulic cylinder 10 and the auxiliary roller right hydraulic cylinder 11 are synchronously extended and retracted to drive the left and right ends of the auxiliary roller 4 to move vertically synchronously, ensuring that the auxiliary roller 4 is always in a horizontal state during the movement. The front roller lifting drive device includes a front roller left hydraulic cylinder 12 and a front roller right hydraulic cylinder 13 respectively connected to the left end and the right end of the front roller 5, and the piston rods of the front roller left hydraulic cylinder 12 and the front roller right hydraulic cylinder 13 are synchronously extended and retracted to drive the left and right ends of the front roller 5 to move vertically synchronously, and the front roller 5 is always in a horizontal state during the lifting process. The rear roller lifting drive device includes a rear roller left hydraulic cylinder 14 and a rear roller right hydraulic cylinder 15 respectively connected to the left end and the right end of the rear roller 7, and the piston rods of the rear roller left hydraulic cylinder 14 and the rear roller right hydraulic cylinder 15 are synchronously extended and retracted to drive the left and right ends of the rear roller 7 to move vertically, and the rear roller 7 is always in a horizontal state during the lifting process. The closed-loop control process of the positions of the front roller 5, the auxiliary roller 4, and the rear roller 7 in the present invention involves the problem of synchronous control of the left and right hydraulic cylinders. In the motion controller 2, the deviation axis is defined and the deviation control command is compensated to the left or right hydraulic cylinder to realize dual-cylinder synchronous control, thereby improving the positioning accuracy and parallelism of each roller. This synchronous control is a prior art and will not be described in detail in the present invention.

In order to reduce the hardware cost, the auxiliary roller 4, the front roller 5, and the rear roller 7 of the corrugated plate rolling machine are divided into three groups and controlled in sequence during the control process. Specifically, the axis hanging function is used in the motion controller 2 to use the two-way analog closed-loop control in the controller to control the closed-loop movement of the hydraulic cylinders on the left and right sides of the auxiliary roller 4.

When the front roller 5 reaches the predetermined position, the middle unhooking and axis hanging functions are also used for the closed-loop movement of the hydraulic cylinders on the left and right sides of the rear roller 7. In this way, two-way analog closed-loop axes are used to realize 6-way closed-loop control, thereby reducing hardware costs.
