[0002] The can sealing machine is used for packaging and forming cans. The packaging cans include a can body and a can lid. The can sealing machine seals the bottom and cover of the cylindrical can body. When the existing can sealing machine is working, the can body is brought to the can body slot of the turntable assembly by a conveyor belt. The turntable assembly rotates to bring the can body at the can body slot into the machine. The turntable assembly has two layers and is arranged separately. The upper layer is used to accommodate the can lid, and the lower layer is used to accommodate the can body. When the turntable assembly rotates to the rolling and sealing station, the lifting mechanism located at the rolling and sealing station drives the can body and the can lid to rise, and the can lid is pressed onto the can body by the pressure head. At the same time, the edge of the can lid is rolled and sealed on the can body by the edge sealing device.

[0003] For example, Chinese patent publication number CN209226546U discloses a turntable assembly for a can seamer adapted to different can heights.

[0023] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0024] See also Figure 1-5 The utility model provides a technical solution: a can sealing machine adapted to different can heights, comprising a chassis 1, a rotating assembly 4, and a turntable assembly 2 and a guide mechanism 3 respectively provided on one side of the top of the chassis 1;

[0025] The turntable assembly 2 includes a tank cover layer 21 and a tank body layer 22. The tank cover layer 21 can be adjusted and installed on the top of the tank body layer 22. The tank body layer 22 is connected to the rotating assembly 4. A threaded screw block 5 is rotatably installed at the center of the top of the tank body layer 22. The tank cover layer 21 and the threaded screw block 5 are connected by threaded fit. A first connecting column 211 and a second connecting column 221 are fixedly installed at equal intervals on the circumference of the adjacent surfaces of the tank cover layer 21 and the tank body layer 22. A connecting block 212 is provided between the first connecting column 211 and the second connecting column 221. A compression spring 222 is provided at the bottom of the inner wall of the second connecting column 221.

[0026] With the opening of the tank body groove 220 facing the outside of the tank body layer 22, the tank cover hole 210 and the tank body groove 220 are rotated by the servo motor in the rotating assembly 4, and the corresponding tank body can be transferred to the feeding station and the sealing station. The tank cover and the tank body can be pressed together by the pressure head assembly on the top of the chassis 1. The tank body sealing technical solution is an existing technology and will not be described in detail here.

[0027] By screwing the threaded screw block 5, the tank cover layer 21 in the turntable assembly 2 can be adjusted downward to a distance from the tank body layer 22 under the cooperation of the connecting column, the connecting block 212 and the compression spring 222, so that the distance between the tank cover layer 21 and the tank body layer 22 can be flexibly adjusted, thereby being suitable for feeding and capping tanks of different heights. The tank cover holes 210 and the tank body grooves 220 adjacent to each other in the turntable assembly 2 are guided and supported by the first connecting column 211, the second connecting column 221 and the connecting block 212, so that after the distance between the tank cover layer 21 and the tank body layer 22 is adjusted, deformation and damage during the transportation and capping of bottles and cans can be avoided.

[0028] Among them, tank cover holes 210 are opened at equal intervals on the top circumference of the tank cover layer 21, and tank body grooves 220 are opened correspondingly on the top circumference of the tank body layer 22, and the tank body grooves 220 are U-shaped openings. Through the opening of the tank body grooves 220 facing the outside of the tank body layer 22, the tank cover holes 210 and the tank body grooves 220 are rotated to the corresponding feeding station and sealing station by the servo motor in the rotating component 4.

[0029] Among them, the connecting block 212 is fixedly installed in the inner wall of the first connecting column 211, and the connecting block 212 is movably inserted into the inner wall of the second connecting column 221 at one end away from the first connecting column 211. The connecting block 212 and the inner wall of the second connecting column 221 are connected by a compression spring 222. By screwing the threaded screw block 5, the tank cover layer 21 in the turntable assembly 2 can be adjusted downward to the distance from the tank body layer 22 under the cooperation of the connecting column, the connecting block 212 and the compression spring 222, so that the distance between the tank cover layer 21 and the tank body layer 22 in the turntable assembly 2 can be flexibly adjusted, so that it can be suitable for feeding and capping tanks of different heights.

[0030] Among them, the rotating component 4 includes a servo motor, and the can layer 22 is fixedly installed on the output end of the servo motor. After the servo motor in the rotating component 4 rotates, the can cover hole 210 and the can groove 220 can be transferred to the feeding station and the sealing station.

[0031] Among them, the guide mechanism 3 includes an upper rib 31 and a lower rib 32. Both the upper rib 31 and the lower rib 32 are arc-shaped. The lower rib 32 is fixedly rotated on the top side of the chassis 1. A telescopic rod 33 is fixedly installed on the top of the lower rib 32. A positioning bolt 330 is fixedly installed on the outside of the telescopic rod 33. The movable end of the telescopic rod 33 is fixedly connected to the upper rib 31. A connecting groove 310 is provided on the side of the upper rib 31 close to the tank cover layer 21. The tank cover layer 21 slides in the connecting groove 310. The upper rib 31 and the lower rib 32 in the guide mechanism 3 can be telescopically adjusted by the telescopic rod 33 and can be positioned by the positioning bolt 330, so that the upper connecting groove 310 of the upper rib 31 can match the height of the tank cover layer 21, and the tank cover layer 21 can slide in the adjusted connecting groove 310, thereby playing a role in stabilizing and guiding the adjusted tank cover layer 21.

[0032] Working principle: When in use, the opening of the tank body groove 220 faces the outside of the tank body layer 22, and the tank cover hole 210 and the tank body groove 220 are rotated by the servo motor in the rotating assembly 4, so that the corresponding tank body can be transferred to the feeding station and the sealing station, and the tank cover and the tank body can be pressed together by the pressure head assembly on the top of the chassis 1;

[0033] When the distance between the can cover layer 21 and the can body layer 22 in the turntable assembly 2 is adjusted to adapt to the sealing of cans of different heights, by screwing the threaded screw block 5, the can cover layer 21 in the turntable assembly 2 can be adjusted downwardly to the distance between the can body layer 22 under the cooperation of the connecting column, the connecting block 212 and the compression spring 222, so that the distance between the can cover layer 21 and the can body layer 22 can be flexibly adjusted, thereby being suitable for feeding and sealing cans of different heights. The first connecting column 211, the second connecting column 221 and the connecting block 212 guide and support the can cover holes 210 and the can body grooves 220 of each two in the turntable assembly 2, so that after the distance between the can cover layer 21 and the can body layer 22 is adjusted, deformation and damage can be avoided during the transportation and sealing of bottles and cans;

[0034] Then, the upper rib 31 and the lower rib 32 in the guide mechanism 3 can be telescopically adjusted by the telescopic rod 33 and can be positioned by the positioning bolt 330, so that the upper connecting groove 310 of the upper rib 31 can match the height of the tank cover layer 21, and the tank cover layer 21 can slide in the adjusted connecting groove 310, thereby playing a role in stabilizing and guiding the adjusted tank cover layer 21.
