Figure 6 The upper and lower ends of the positioning shaft 22 are respectively provided with a locking disc 221 and a positioning disc 222, and a straight groove 223 is provided between the locking disc 221 and the positioning disc 222. Figure 5The upper end of the locking disk 221 is provided with a first dividing groove 100 and a second dividing groove 200, one end of the first dividing groove 100 passes through the first axial hole 21 and is connected with the second dividing groove 200, and the other end passes through the outer wall of the locking disk 221; the first dividing groove 100 is connected with the slot 223, and the locking disk 221 is provided with a clamping bolt 224 at the first dividing groove 100; the dial core seat 2 is connected to the dial 4 through the positioning pin 3, and the dial 4 is provided with a second axial hole 41 adapted to the positioning disk 222, refer to the attached Figure 3 and attached Figure 4 The dial 4 is provided with a locking assembly 5, which is used to fix the dial 4 to the dial core seat 2. In the present invention, the dial core seat 2 is sleeved on the dial shaft 1 through the first shaft hole 21. Figure 7 , tighten the clamping bolt 224, the locking plate 221 between the clamping bolt 224 and the first shaft hole 21 approaches the first shaft hole 21, and the two sides of the dial shaft 1 in the first shaft hole 21 (the two sides of the dial shaft 1 are roughly the two end directions of the clamping bolt 224) contact the locking plate 221, continue to tighten the clamping bolt 224, the locking plate 221 between the second partition groove 200 and the first shaft hole 21 approaches the direction of the clamping bolt 224, and the contact between the dial shaft 1 in the first shaft hole 21 and the locking plate 221 changes from a line to a surface, and the increased contact area is mostly close to the second partition groove 200. This setting makes the locking plate 221 hold the dial shaft 1 in the first shaft hole 21 well, and it is also conducive to improving the coaxiality of the locking plate 221 and the dial shaft 1, which is conducive to the accurate entry and exit of the bottle on the dial 4. Secondly, it is conducive to eliminating the matching clearance and improving the positioning accuracy of the dial 4, especially it is very convenient to adjust the angle and orientation of the intersection of the dial 4. Third, the fixation of the dial core seat 2 and the dial shaft 1 is completed by a clamping bolt 224, which effectively improves the installation speed of the dial core seat 2 and the dial shaft 1. After the dial core seat 2 is fixed, the dial 4 is installed on the dial core seat 2 through the positioning plate 222, ensuring that the dial 4 and the dial core seat 2 are coaxially arranged, and then the dial 4 is connected to the dial core seat 2 through the positioning pin 3, and then fixed by the locking assembly 5. In this structural design, when replacing the dial 4, only the locking assembly 5 needs to be disassembled, and the dial core seat 2 does not need to be disassembled. In addition, the positioning installation method of the positioning pin 3 makes it unnecessary to adjust the handover position when replacing the dial 4, which greatly improves the production efficiency of replacing specification parts.

[0029] As another embodiment of the present invention: Figure 8 The first dividing groove 100 between the second dividing groove 200 and the first axial hole 21 extends downward to the bottom of the dial core seat 2. This design can reduce the connection strength of the locking plate 221 between the second dividing groove 200 and the first axial hole 21. In the process of fixing the locking plate 221 and the dial shaft 1, it is beneficial to make the locking plate 221 between the second dividing groove 200 and the first axial hole 21 approach the direction of the clamping bolt 224.

[0030] As another embodiment of the present invention: Fig. 9 The second dividing groove 200 extends downward to the bottom of the dial core seat 2. This design can reduce the connection strength of the locking plate 221 between the second dividing groove 200 and the first axial hole 21. In the process of fixing the locking plate 221 and the dial shaft 1, it is beneficial to make the locking plate 221 between the second dividing groove 200 and the first axial hole 21 approach the direction of the clamping bolt 224.

[0031] As another embodiment of the present invention, the first dividing groove 100 and the second dividing groove 200 are vertically distributed. This structural design is beneficial to improving the coaxiality of the locking disk 221 and the dial shaft 1.

[0032] As another embodiment of the present invention: the first axial holes 21 are symmetrically distributed along the first dividing groove 100 . This structural design is beneficial to improving the coaxiality of the locking disk 221 and the dial shaft 1 .

[0033] One installation method of the positioning pin 3: a disc 23 is provided at the lower end of the dial core seat 2, the positioning shaft 22 is fixed at the upper end of the disc 23, the diameter of the disc 23 is larger than the diameter of the positioning shaft 22, and the positioning screw 6 passes through the disc 23 and is threadedly connected to the positioning pin 3. The positioning pin 3 is fixed on the disc 23 by the positioning screw 6, and the dial is installed from top to bottom, which is conducive to reducing the difficulty of installation and improving the installation speed.

[0034] As another embodiment of the present invention: a positioning groove 231 adapted to the positioning pin 3 is provided on the disc 23. In this structural design, the positioning groove 231 is used to improve the installation accuracy of the positioning pin 3 and also facilitates a stronger connection between the positioning pin 3 and the disc 23.

[0035] An implementation of the locking assembly 5: The locking assembly 5 includes a cover plate 51 and a screw handle 52, wherein the cover plate 51 is located above the dial 4, and the screw handle 52 passes through the cover plate 51 and is threadedly connected to the dial shaft 1. With this structural design, the screw handle 52 can be manually screwed to press the cover plate 51, thereby fixing the dial 4.

[0036] Another implementation of the locking assembly 5: the locking assembly 5 includes a locking screw, which passes through the dial 4 and is threadedly connected to the dial core seat 2.

[0037] As another embodiment of the present invention: the dial 4 is provided with an avoidance hole 42 at the clamping bolt 224, and the avoidance hole 42 is connected with the second shaft hole 41. Through this structural design, when it is necessary to adjust the intersection position of the dial 4, there is no need to disassemble the dial 4. It is only necessary to use an Allen wrench to loosen the clamping bolt 224 of the dial core seat 2 in the avoidance hole 42 of the dial 4, rotate the dial 4 to rotate it to a suitable position, and then tighten the clamping bolt 224. The intersection position adjustment is very convenient and time-saving.

[0038] As another embodiment of the present invention: the avoidance hole 42 and the positioning pin 3 are both covered by the cover plate 51 .

[0039] Specifically, a step is provided on the dial shaft 1, and when the dial core seat 2 is sleeved on the dial shaft 1, its bottom is tightly pressed against the step surface.

[0040] In the present invention, the dial core seat 2 is clamped on the step of the dial shaft 1 by the clamping bolt 224 to perform vertical axial height positioning and radial locking positioning, the positioning pin 3 is fixed to the dial core seat 2 by the positioning screw 6, the dial 4 is coaxially arranged with the dial core seat 2 by the positioning plate 222, and then positioned and connected by the positioning pin 3, and finally the cover plate 51 is pressed against the dial 4 by the screw 52. When changing the bottle specification, only the screw 52 needs to be manually unscrewed to take out the cover plate 51 and the dial 4. Align the dial 4 that adapts to the bottle specification size with the positioning pin 3 on the dial core seat 2, quickly place it on the positioning pin 3, and then manually tighten the screw 52, ​​and use the cover plate 51 to press the dial 4 to complete the replacement of the dial 4. The present invention adopts the positioning technology of the dial core seat 2 and the positioning pin 3 to determine the center and orientation of the dial 4. When changing the bottle specification, only the screw 52 needs to be manually unscrewed to take out the cover plate 51 and the dial 4, and there is no need to adjust the handover position, which greatly improves the production efficiency of changing specification parts. The dial core seat 2 uses a clamping bolt 224 to clamp the dial shaft 1, and no longer uses the key connection method of the prior art solution, which completely eliminates the matching clearance of the key connection method, and the intersection position is more accurately positioned. If the intersection position of the dial 4 needs to be adjusted, it is not necessary to disassemble the dial 4. It is only necessary to loosen the clamping bolt 224 in the avoidance hole 42 of the dial 4 with an inner hexagonal wrench, rotate the dial 4 to rotate it to a suitable position, and then tighten the clamping bolt 224. The intersection position adjustment is very convenient and time-saving.
