[0016] The following is combined with Figure 1-4 The specific implementation methods of the utility model are further described in detail.

[0017] Embodiment 1, the technical solution is that when the present application is in use, the two supporting inclined plates 2 above the bed 1 form a V-shaped structure, which can support the tank body 25 of the PPH liquid storage tank of different diameters, and the tank body 25 is placed at the two supporting inclined plates 2, and then the height of the driving motor 6 is adjusted by adjusting the hand wheel 24 to drive the lifting and lowering adjustment device 4, so that the output shaft 7 of the motor is aligned with the tank body 25, so as to facilitate the operation of the cutting device 9. When the cutting device 9 is used for cutting, the electric cutting machine 17 and the controller 10 are started, and the driving motor 6 is started at the same time. The driving motor 6 drives the mounting plate 8 together with the cutting device 9 to rotate around the tank body 25, so as to facilitate the operation of the cutting device 9. During cutting, the controller 10 controls the stepping motor 18 to work according to the set cycle. Every time the cutting device 9 rotates with the mounting plate 8 for a certain period of time, the stepping motor 18 controls the screw to rotate the set stroke, thereby driving the electric cutting machine 17 to feed the set depth, so as to completely cut the tank body 25. The present application has a simple structure, is easy to use, has strong practicality, has high cutting efficiency and liberates manpower.

[0018] Embodiment 2, based on embodiment 1, specifically, when the present application is used, the frame 3 and the bed 1 are fixed on the workshop floor by anchor bolts or casting, and the tank 25 to be cut is placed on the two supporting inclined plates 2 as shown in the attached drawings of the specification. The tank 25 has a certain deadweight, and the cutting operation can be completed without applying an additional fixing device. Then, the height of the drive motor 6 can be adjusted according to the position of the axis of the tank 25, so as to facilitate the operation of the cutting device 9. When adjusting, the adjustment hand wheel 24 is turned clockwise to drive the screw 21 to rotate, and the rotation of the screw 21 will drive the large bracket 5 through the large screw sleeve 22, and the large bracket 5 is restricted by the vertical sliding cooperation of the large sliding sleeve 23 and the sliding rod 20, so the screw 21 will drive the large bracket 5 to move downward along the sliding rod 20 as the adjustment hand wheel 24 rotates clockwise, and then the drive motor 6 will also move downward with the large bracket 5; correspondingly, the counterclockwise rotation of the hand wheel will cause the screw 21 to drive the drive motor 6 to move downward with the large bracket 5, and then the height of the drive motor 6 can be adjusted. It is sufficient to adjust the output shaft 7 of the driving motor 6 to be roughly aligned with the can body 25, so that the two sets of cutting devices 9 can cut the can body 25 at the same time, thereby improving the cutting efficiency.

[0019] During cutting, the drive motor 6 is started, and the output shaft 7 of the drive motor 6 drives the mounting plate 8 together with the cutting device 9 to rotate around the outer edge of the tank body 25, so that the cutting operation can be performed. During cutting, the electric cutting machine 17 and the control and stepper motor 18 should also be in the starting state. The controller 10 can control the stepper motor 18 to work according to the set cycle. Every time the cutting device 9 rotates with the mounting plate 8 for a certain period of time, the stepper motor 18 controls the screw to rotate the set stroke. Specifically, every time the mounting plate 8 rotates for a certain period of time, that is, the cutting device 9 rotates around the tank body 25 for cutting for a certain period of time, the controller 10 controls the stepper motor 18 on the connecting plate 12 to rotate forward by the set stroke. The forward rotation of the stepper motor 18 will drive the adjusting screw 13 to rotate forward. The forward rotation of the adjusting screw 13 will act on the small bracket 16 through the small screw sleeve 14, and the small bracket 16 is restricted by the small sliding sleeve 15 and the vertical rod 11. Therefore, the forward rotation of the adjusting screw 13 will drive the small bracket 16 to move a corresponding distance along the vertical rod 11 close to the axis direction of the tank body 25. At the same time, the electric cutting machine 17 on the small bracket 16 also moves a corresponding distance close to the axis direction of the tank body 25, that is, the feeding depth of the electric cutting machine 17 is deepened, and the cutting of the tank body 25 can be completed.

[0020] Embodiment 3, based on embodiment 2, the controller 10 is a PLC controller 10, and can also control the stepper motor 18 to drive the adjusting screw 13 to reverse, thereby driving the small bracket 16 and the electric cutting machine 17 to reverse and reset. Its specific control logic can be adopted from the prior art, and this application will not describe it in detail. This application uses a battery 19 to power the electric cutting machine 17, the controller 10, and the stepper motor 18 to avoid entanglement of the pulling wire during the rotation process.
