[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] Reference Figure 2-4, the utility model provides an embodiment: a capping device for a capping machine, comprising a chassis 1, a driving cabinet 2 is arranged on the top of the chassis 1, a lifting assembly is arranged between the chassis 1 and the driving cabinet 2, a motor 3 is arranged on one side of the driving cabinet 2, a bidirectional threaded column 4 is fixedly connected to the output end of the motor 3, a connecting block 5 is threadedly connected to the outer wall of the bidirectional threaded column 4, a slider 6 is slidably connected to the inside of the connecting block 5, a clamping plate 7 is fixedly connected to the lower surface of the slider 6, a fixing block 8 is fixedly connected to one side of the connecting block 5, a sliding column 9 is slidably connected to the inside of the fixing block 8, a spring 10 is sleeved on the outer wall of the sliding column 9, one end of the spring 10 is fixedly connected to the inside of the fixing block 8, the other end of the spring 10 is fixedly connected to the outer wall of the sliding column 9, the sliding column 9 passes through the connecting block 5 and extends to the inside of the sliding block 6, the bidirectional threaded column 4 is rotatably connected to the inside of the driving cabinet 2, a tank body 21 is arranged on the upper surface of the chassis 1, a tank cover 22 is threadedly connected to the inside of the tank body 21, and a pull handle 11 is fixedly connected to one end of the sliding column 9;

[0030] Specifically, by pulling the handle 11, the slide post 9 is pulled, so that the position of the slider 6 will no longer be engaged by the slide post 9, so that the slider 6 can slide smoothly and drive the clamping plate 7 to disengage, and when the slide post 9 is pulled, the spring 10 will be squeezed due to the displacement of the slide post 9. In this way, when installing a new clamping plate 7, after the slider 6 slides and docks into the inside of the connecting block 5, the handle 11 can be released, so that the spring 10 can restore itself and drive the slider 9 to be pushed back to its original position, thereby engaging the position of the slider 6 and fixing the position of the clamping plate 7. After replacing the clamping plate 7, the motor 3 can be driven to rotate the bidirectional threaded column 4, thereby driving the connecting blocks 5 and the clamping plates 7 on both sides to move synchronously, thereby clamping the tank cover 22.

[0031] Reference Figure 1 The lifting assembly includes a telescopic column 12, a hydraulic push rod 13, a connecting plate 14 and a second motor 15. The output end of the hydraulic push rod 13 is fixedly connected to the lower surface of the connecting plate 14. One end of the telescopic column 12 is fixedly connected to the side wall of the connecting plate 14. The second motor 15 is fixedly connected to the inside of the connecting plate 14. The output end of the second motor 15 passes through the connecting plate 14 and is fixedly connected to the upper surface of the drive cabinet 2. The telescopic column 12 and the hydraulic push rod 13 are fixedly connected to the upper surface of the chassis 1.

[0032] Reference Figure 2-3 Specifically, the connecting plate 14 is pushed by the hydraulic push rod 13 to be raised and lowered under the restriction of the telescopic column 12, so that the driving motor 2 15 can drive the driving cabinet 2 to rotate synchronously, so that the bottle cap clamped by the driving cabinet 2 is driven to rotate, thereby screwing and sealing.

[0033] A plurality of rubber pads 16 are fixedly connected to the outer wall of the clamping plate 7, and the rubber pads 16 are evenly distributed according to the length of the clamping plate 7. An inclined slot plate 17 is slidably connected inside the clamping plate 7. A fixed column 18 is fixedly connected inside the clamping plate 7. A limiting column 19 is slidably connected inside the fixed column 18. One end of the limiting column 19 is fixedly connected to the lower surface of the inclined slot plate 17. A spring 20 is sleeved on the outer wall of the limiting column 19. One end of the spring 20 is fixedly connected to the upper surface of the fixed column 18, and the other end of the spring 20 is fixedly connected to the inside of the inclined slot plate 17.

[0034] Specifically, when the clamping plate 7 clamps the corresponding position of the bottle cover 22, the friction force can be increased by the rubber pad 16, and when the bottle cover is just clamped at the corresponding position, the inclined groove plate 17 will be acted upon by a force, thereby driving the limiting column 19 to slide in the fixed column 18, and squeezing the spring 20 at the same time, so that the elastic potential energy generated by the spring 20 can react to the clamped position of the corresponding bottle cover 22 through the inclined groove plate 17, thereby increasing the stability during clamping.

[0035] Working principle: when it is necessary to use the equipment to clamp the tank cover 22 for rotation, we first pull the handle 11 to make the slide post 9 move synchronously, so that the slide post 9 can be separated from the inside of the slider 6, so that the slider 6 can slide smoothly and drive the clamping plate 7 to be separated together, and when the slide post 9 is pulled, the spring 10 will be pulled and squeezed. In this way, when installing a new clamping plate 7, after the slider 6 is re-engaged in the corresponding connecting block 5, the pulling force applied to the handle 11 can be cancelled, so that the spring 10 can generate the force of elastic potential energy to push the slide post 9 back to its original position, thereby engaging the position of the slider 6 and fixing the position of the clamping plate 7, so that the corresponding clamping plate 7 can be quickly replaced to the size suitable for the corresponding tank cover 22. At this time, the hydraulic push rod 13 is started again to let The push connecting plate 14 drives the driving cabinet 2 to move up and down under the restriction of the telescopic column 12. When the driving cabinet 2 reaches the position required to clamp the tank cover 22, the motor 1 3 is started again, so that the two-way threaded column 4 is driven to rotate, thereby driving the connecting blocks 5 and the clamping plate 7 on both sides to move toward the center position, so as to clamp the tank cover 22. At this time, the inclined slot plate 17 will be subjected to force first, so that the limiting column 19 slides in the fixed column 18 while exerting a squeezing force on the spring 2 20. At this time, the spring 20 will, through the interaction of forces, push the inclined slot plate 17 to further stabilize the clamping position of the tank cover 22, and then cooperate with the rubber pad 16 to prevent the tank cover 22 from slipping, so that when the motor 2 15 drives the driving cabinet 2 to drive the tank cover 22 to rotate synchronously, it can be more stable and not easy to fall off.

[0036] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
