[0021] The guide plate 2 of the utility model is radially distributed with a plurality of guide slots 4, and the guide slots 4 are all oriented toward the center of the guide plate 2 to ensure that the tank body is located at the center of the guide plate 2. A plurality of positioning posts 3 are slidably arranged in the guide slots 4, and the positioning posts 3 are used to position the tank body. The driving plate 1 is rotatably connected to the guide plate 2, and the driving plate 1 is provided with a plurality of arc-shaped through holes 5 for the positioning posts 3 to pass through. The driving plate 1 rotates to drive the positioning posts 3 on the guide plate 2 to synchronously scale, and the tank body is fixed or released, thereby realizing the positioning of tank bodies of different diameters at the center of the driving plate 1, with a simple structure and convenient operation.

[0022] like Figures 1 to 3 As shown, it also includes a slider 6, the open end of the guide slot 4 located on the side of the guide disk 2 is in a "convex" shape, the slider 6 is inserted from the open end of the guide slot 4 and slides to the closed end of the guide slot 4, one end of the positioning column 3 is fixed on the slider 6, and the other end of the positioning column 3 passes through the arc through hole 5. The open end of the guide slot 4 on the side of the wire disk of this embodiment is in a "convex" shape, the slider 6 is inserted from the open end of the guide slot 4 and slides to the closed end of the guide slot 4, one end of the positioning column 3 is fixed on the slider 6, and the "convex" design limits the slider 6 to slide only in the guide slot 4, and the open end on the side of the guide disk 2 also facilitates the installation of the slider 6 and the positioning column 3. As for the length of the guide slot 4, it can be set according to actual needs. The longer the length of the guide slot 4, the more tanks with different diameters can be positioned.

[0023] like Figure 1 and Figure 3As shown, the diameter of the driving disk 1 is larger than the diameter of the guide disk 2. In this embodiment, the diameter of the driving disk 1 is larger than the diameter of the guide disk 2. This design facilitates the user's hand to rotate the driving disk 1 through the edge of the driving disk 1. In other embodiments, the diameter of the driving disk 1 can also be designed to be the same as the diameter of the guide disk 2, and only a bump or other structure that can be operated by the user's hand is added to the driving disk 1 to achieve the same rotation effect.

[0024] like Figure 1 and Figure 2 As shown, the number of the guide slots 4 and the arc-shaped through holes 5 are at least three, and the width of the arc-shaped through holes 5 matches the diameter of the positioning column 3. Since at least three positioning columns 3 are required to position the tank body, the guide slots 4 of this embodiment are set to three, which can minimize the processing steps and save production costs while ensuring that the tank body can be accurately positioned. The arc-shaped through holes 5 are also set to three accordingly. In other embodiments, the number of the guide slots 4 and the arc-shaped through holes 5 can also be adjusted according to actual needs. The width of the arc-shaped through holes 5 matches the diameter of the positioning column 3, so that when the drive disk 1 is rotated, the inner side wall of the arc-shaped through holes 5 can accurately push the positioning column 3 to reciprocate in the guide slot 4. In this embodiment, the distance between the positioning columns 3 is reduced when the drive disk 1 is rotated clockwise, and the distance between the positioning columns 3 is expanded when the drive disk 1 is rotated counterclockwise.

[0025] like Figures 1 to 3 As shown, the drive disk 1 further includes a bolt 7, a through hole 8 is provided at the center of the circle of the drive disk 1, a threaded blind hole 9 is provided at the center of the circle of the guide disk 2, and the bolt 7 passes through the through hole 8 of the drive disk 1 and cooperates with the threaded blind hole 9 of the guide disk 2, so that the drive disk 1 is rotatably connected to the guide disk 2. In this embodiment, a through hole 8 is provided at the center of the circle of the drive disk 1, and a threaded blind hole 9 is provided at the center of the circle of the guide disk 2, and the depth of the threaded blind hole 9 is less than the length of the bolt 7, so when the bolt 7 passes through the through hole 8 of the drive disk 1 and cooperates with the threaded blind hole 9 of the guide disk 2 for locking, the drive disk 1 can rotate around the bolt 7.

[0026] like Figure 2 and Figure 3As shown, it also includes a base 10 and a cylindrical connector 11. The base 10 is fixedly arranged on the can sealing machine. The base 10 is provided with a first cylindrical boss 12, and the bottom of the guide plate 2 is provided with a second cylindrical boss 13; the cylindrical connector 11 is fixedly arranged on the base 10 in cooperation with the first cylindrical boss 12, and the guide plate 2 is movably sleeved in the cylindrical connector 11 through the second cylindrical boss 13. The base 10 of this embodiment is fixedly arranged on the can sealing machine, which is convenient for can sealing operations on the positioned can body. The base 10 is provided with a first cylindrical boss 12, and the bottom of the guide plate 2 is provided with a second cylindrical boss 13. The cylindrical boss is matched with the cylindrical connector 11, so that the installation process is more convenient, and the cylindrical shape is consistent with the can body, which is more beautiful.

[0027] like Figure 2 and Figure 3 As shown, the inner surface of the cylindrical connector 11 and the outer surface of the first cylindrical boss 12 are provided with mutually matching threads, and the cylindrical connector 11 and the first cylindrical boss 12 are fixedly connected by threads. In this embodiment, the cylindrical connector 11 and the first cylindrical boss 12 are fixed by threaded connection, and other connection methods can also be used for fixing in other embodiments.

[0028] like Figure 2 and Figure 3 As shown, the guide plate 2 further includes a compression spring 14. The first cylindrical boss 12 and the second cylindrical boss 13 are respectively provided with a plurality of corresponding blind holes 15 along the axial direction. The two ends of the plurality of compression springs 14 are respectively against the blind holes 15 of the first cylindrical boss 12 and the blind holes 15 of the second cylindrical boss 13, so that the guide plate 2 is movably sleeved in the cylindrical connector 11 through the second cylindrical boss 13. Since the can seamer has an impact force when it contacts the can cover during the can seaming operation, the compression spring 14 is arranged inside the cylindrical connector 11 in this embodiment to provide a certain buffering effect and ensure the smooth progress of the can seaming operation.

[0029] like Figure 2 As shown, the number of the compression springs 14 and the blind holes 15 are both four, and the blind holes 15 are evenly distributed on the first cylindrical boss 12 and the second cylindrical boss 13. In this embodiment, the number of the compression springs 14 and the blind holes 15 are both four, and the blind holes 15 are evenly distributed on the first cylindrical boss 12 and the second cylindrical boss 13, so that the force is more balanced. In other embodiments, the number of the compression springs 14 and the blind holes 15 can also be adjusted.

[0030] The use process of the utility model is as follows:

[0031] The user first rotates the drive disk 1 counterclockwise to maximize the spacing between the positioning posts 3, and then places the can body to be sealed between the positioning posts 3 of the drive disk 1 and covers the can cover. The drive disk 1 is rotated clockwise, and the positioning posts 3 are driven by the inner wall of the arc-shaped through hole 5 and slide along the guide slots 4 through the slider 6 until they abut against the outer periphery of the can body. Since the guide slots 4 face the center of the guide disk 2 and are evenly distributed around the center of the guide disk 2, when the positioning posts 3 abut against the outer periphery of the can body, the can body is at the center of the drive disk 1, and the positioning of the can body is completed, and then the can sealing operation can be carried out.
