[0024] The utility model is now further described in conjunction with the accompanying drawings and specific implementation methods.

[0025] The utility model provides a lifting structure of an automatic can sealing machine, such as Figures 1 to 5As shown, it includes a body and a control panel 1, a first microswitch 2, a third microswitch 4, a first motor 5, a second motor 6, a guide rail 7, a loading platform 8 and a canning mechanism arranged on the body; the control panel 1 is respectively connected to the first microswitch 2, the third microswitch 4, the first motor 5 and the second motor 6; the guide rail 7 is longitudinally arranged in the middle of the body, and a loading platform 8 for loading the can body is slidably arranged on the guide rail 7 up and down, the loading platform 8 is connected to the first motor 5, the canning mechanism is arranged above the loading platform 8 and connected to the second motor 6, the canning mechanism is used to abut the top of the can body and perform canning operations, the loading platform 8 is provided with a first microswitch 2 for triggering the can body abutting against the canning mechanism, and the canning mechanism is provided with the third microswitch 4.

[0026] The loading platform 8 of the utility model is connected to the first motor 5 and is slidably arranged on the guide rail 7 in the middle of the machine body, so that cans of different heights can be directly placed on the loading platform 8 without adjusting the structure of the loading platform 8. The can is placed on the loading platform 8, and the control panel 1 controls the first motor 5 to drive the loading platform 8 to rise. The can sealing mechanism above the loading platform 8 abuts against the top of the can, thereby triggering the first micro switch 2 on the loading platform 8. The control panel 1 controls the second motor 6 to drive the can sealing mechanism to perform the can sealing operation. After the can sealing operation is completed, the can sealing mechanism triggers the third micro switch 4, and the first motor 5 drives the loading platform 8 to descend along the guide rail 7. The operation is simple and easy to use, and can automatically seal cans of different heights.

[0027] like Figure 5 As shown, it also includes a second micro switch 3 and a contact plate 22. The contact plate 22 is arranged on the bottom plate. The second micro switch 3 is connected to the control panel 1. The second micro switch 3 is arranged on the stage 8 and is in active contact with the contact plate 22 along the movement path of the stage 8. The second micro switch 3 is also arranged on the stage 8 of this embodiment. When the canning operation is completed, the travel switch 9 responds, and the control panel 1 controls the first motor 5 to reverse and drive the stage 8 to descend. The second micro switch 3 on the stage 8 hits the contact plate 22 on the bottom plate of the canning machine and is triggered. At this time, the control panel 1 controls the first motor 5 to stop rotating, so that the stage 8 stops descending. The design is ingenious. The contact plate 22 of this embodiment is L-shaped and is arranged at a position matching the second micro switch 3. In other embodiments, the shape of the contact plate 22 can also be adjusted according to actual needs.

[0028] like Figure 4As shown, the can sealing mechanism includes a transmission mechanism 10, a pressure head 11 and a roller 12, the transmission mechanism 10 is connected to the second motor 6, the roller 12 is connected to the transmission mechanism 10, the pressure head 11 is against the inner edge of the top surface of the can cover, and the second motor 6 drives the roller 12 to abut against the outer edge of the can cover through the transmission mechanism 10 to cooperate with the pressure head 11 to perform can sealing operations. The pressure head 11 of this embodiment is used to fix the can body and abut against the inner edge of the top surface of the can cover, the second motor 6 is used to drive the transmission mechanism 10, and the transmission mechanism 10 is connected to the two rollers 12, driving the two rollers 12 to abut against the outer edge of the can cover, the pressure head 11 and the roller 12 cooperate inside and outside to perform can sealing operations, the can sealing effect is good, no manual operation is required, and the can sealing efficiency is improved.

[0029] like Figure 3 and Figure 5 As shown, it also includes a travel switch 9. The can sealing mechanism is provided with a travel switch 9 for recording the can sealing travel of the can sealing mechanism. The third micro switch 4 is provided on the travel path of the travel switch 9.

[0030] In this embodiment, when the can sealing mechanism performs the can sealing operation, the can sealing stroke of the can sealing mechanism will be synchronously transmitted to the travel switch 9, and the travel switch 9 is used to record the can sealing stroke of the can sealing mechanism. After the can sealing operation is completed, the travel switch 9 will trigger the third micro switch 4, so that the control panel 1 controls the first motor 5 to reverse and drive the loading platform 8 to descend. This process is closely linked and conforms to the logic of use.

[0031] Furthermore, the sealing stroke of the sealing mechanism corresponds to the number of revolutions of the second motor 6 driving the transmission mechanism 10. The sealing stroke of the sealing mechanism of this embodiment is related to the diameter of the can body to be sealed. For can bodies with different diameters, the number of revolutions of the second motor 6 is also different, so it can be flexibly adjusted according to actual conditions.

[0032] like Figure 2 , Figure 4 and Figure 5 As shown, it also includes a screw rod 13 and a gear set, the screw rod 13 is longitudinally arranged in parallel behind the guide rail 7, the first motor 5 is arranged at the bottom of the body, the motor shaft 19 of the first motor 5 is connected to the screw rod 13 through the gear set, the loading platform 8 is connected to the screw rod 13, and the first motor 5 drives the loading platform 8 to move up and down through the screw rod 13. This embodiment connects the motor shaft 19 and the screw rod 13 of the first motor 5 through the gear set, and can effectively transmit the rotational power of the motor shaft 19 to the screw rod 13. The screw rod 13 is longitudinally arranged in parallel with the guide rail 7, which makes the structure of the entire body more compact while satisfying the need to drive the loading platform 8 to move up and down, thereby improving the utilization rate of the internal space of the body. In addition, by selecting a gear set with different numbers of teeth, the rotation speed of the screw rod 13 can be adjusted, so that the lifting speed of the loading platform 8 can be flexibly controlled.

[0033] like Figure 2 , Figure 4 and Figure 5 As shown, the slide block 21 is also included. The slide block 21 is slidably arranged on the guide rail 7. One side of the stage 8 is fixedly connected to the slide block 21 and extends to the rear of the guide rail 7 to be connected to the screw rod 13. The screw rod 13 rotates to drive the stage 8 to move up and down along the guide rail 7 through the slide block 21. The stage 8 of this embodiment moves up and down along the guide rail 7 through the slide block 21, which improves the smoothness of the stage 8 when moving, and also improves the stability of the stage 8 when moving.

[0034] like Figure 1 , Figure 4 and Figure 5 As shown, the loading platform 8 includes a bracket 14, a base 15, a compression spring, a guide plate 16 and a driving plate 17. The bracket 14 is connected to the first motor 5. One side of the bracket 14 is slidably arranged on the guide rail 7 up and down, and the other side of the bracket 14 is fixedly provided with the base 15. The compression spring is placed in the base 15. The guide plate 16 is movably arranged on the base 15 up and down through the compression spring. The driving plate 17 is rotatably connected to the guide plate 16 to place and position the can body. The can sealing mechanism abuts against the top of the can body and triggers the first micro switch 2 on the bracket 14 through the driving plate 17 and the compression spring.

[0035] When the first motor 5 of this embodiment drives the bracket 14 to move up and down, the base 15, compression spring (not shown in the figure), guide plate 16 and driving plate 17 on the bracket 14 move up and down in the middle of the machine body together with the bracket 14. When the can body on the driving plate 17 rises to the top of the can body against the can sealing mechanism, since the guide plate 16 is set on the base 15 by the compression spring and moves up and down, the bracket 14 will continue to rise until the guide plate 16 presses down to trigger the first micro switch 2 on the bracket 14, the first motor 5 stops rotating forward, and the second motor 6 starts to rotate to drive the can sealing mechanism to perform the can sealing operation. The compression spring not only has a certain buffering effect, but also ensures that the first micro switch 2 can be triggered smoothly.

[0036] like Figure 4 and Figure 5 As shown, it also includes a positioning column 18, and a plurality of guide grooves (not shown in the figure) are radially distributed on the guide plate 16, the guide grooves are oriented toward the center of the guide plate 16 and are evenly distributed circumferentially around the center of the guide plate 16, the positioning column 18 is slidably arranged in the guide grooves, and the driving plate 17 is provided with a plurality of arc-shaped through holes 20 for the positioning column 18 to pass through, the arc-shaped through holes 20 are evenly distributed circumferentially around the center of the driving plate 17, the driving plate 17 rotates forward or reversely, and the arc-shaped through holes 20 drive the positioning column 18 to synchronously reciprocate in the guide groove, and the spacing between the positioning columns 18 is synchronously scaled to fix or release the tank body, thereby realizing the positioning of the tank body at the center of the driving plate 17.

[0037] The guide plate 16 of this embodiment is radially distributed with a plurality of guide slots, which are all oriented toward the center of the guide plate 16 to ensure that the tank is located at the center of the guide plate 16. A plurality of positioning posts 18 are slidably arranged in the guide slots, and the positioning posts 18 are used to position the tank. The driving plate 17 is provided with a plurality of arc-shaped through holes 20 for the positioning posts 18 to pass through. The driving plate 17 rotates to drive the positioning posts 18 on the guide plate 16 to synchronously scale, and the tank is fixed or released, thereby realizing the positioning of tanks of different diameters at the center of the driving plate 17, with a simple structure and convenient operation.

[0038] like Figure 4 and Figure 5 As shown, the number of the positioning posts 18, the guide slots and the arc-shaped through holes 20 are all at least three. Since at least three positioning posts 18 are required to position the tank body, the guide slots in this embodiment are set to three, which can ensure that the tank body can be accurately positioned while minimizing the processing steps and saving production costs. The arc-shaped through holes 20 are also set to three accordingly. In other embodiments, the number of positioning posts 18, guide slots and arc-shaped through holes 20 can also be adjusted according to actual needs.

[0039] The working process of the utility model is as follows:

[0040] The user first places the can body to be sealed on the driving disk 17, rotates the driving disk 17, and the positioning column 18 positions the can body, and then places the can cover on the can body to start the automatic can sealing operation.

[0041] Press the start button (not shown) of the control panel 1, and the control panel 1 controls the first motor 5 to rotate forward to drive the bracket 14, the can body and the can cover on the driving disk 17 to rise together, until the can cover abuts against the pressure head 11. Since the guide disk 16 is movably arranged on the base 15 by the compression spring, the bracket 14 will continue to rise, and the driving disk 17 presses down to trigger the first micro switch 2 on the bracket 14. At this time, the first motor 5 stops rotating forward, and the second motor 6 starts to rotate to drive the can sealing mechanism to perform the can sealing operation.

[0042] When the can sealing mechanism is performing the can sealing operation, the travel switch 9 on the can sealing mechanism will synchronously record the can sealing stroke. After the can sealing operation is completed, the travel switch 9 triggers the third micro switch 4, so that the control panel 1 controls the first motor 5 to reverse and drive the bracket 14 to descend together with the sealed can on the driving disk 17. At the same time, the second motor 6 stops rotating.

[0043] Since the second micro switch 3 is provided on the bracket 14, when the first motor 5 reverses and drives the bracket 14 to descend until the second micro switch 3 touches the contact plate 22 on the bottom plate of the machine body, the second micro switch 3 is triggered, the control panel 1 controls the first motor 5 to stop, the bracket 14 descends to the bottom of the machine body, and finally the sealed can body is taken out from the driving disk 17, and the can sealing operation is completed.

[0044] The directional terms mentioned in this specification are defined relative to the structures shown in the drawings. They are relative concepts and may change accordingly according to different locations and different usage conditions. Therefore, these or other directional terms should not be interpreted as restrictive terms.

[0045] The above description is only a preferred embodiment of the present utility model and is not a limitation on the design of the present case. Any equivalent changes made based on the key design of the present case shall fall within the protection scope of the present case.
