[0023] To make the purpose, technical solutions, and advantages of the present invention more clear, the following will be combined with the accompanying drawings to clearly and completely describe the technical solutions of the present invention. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] Refer to the attached Figure 2 This embodiment provides a bottle pressing mechanism, including a turntable 2 rotatably arranged on a frame 1, a lifting rod 3 slidably arranged on the turntable 2, a bottle body 4 is provided at the upper end of the lifting rod 3, and a driving member 5 for driving it to rise and fall is connected to the lower end of the lifting rod 3. A positioning plate 6 is fixed to the turntable 2 above the lifting rod 3, and the positioning plate 6 rotates with the turntable 2. A bottle pressing shaft 7 is slidably arranged on the positioning plate 6, and a spring 8 is provided between the bottle pressing shaft 7 and the positioning plate 6. A bottle pressing plate 9 is fixed on the bottle pressing shaft 7. Through this structural design, the bottle pressing plate 9 is installed on the positioning plate 6 by the spring 8. The bottle pressing plate 9 is provided with a bottle pressing hole 10 that matches the bottle body 4. The upper hole diameter of the bottle pressing hole 10 is small and the lower hole diameter is large so as to adapt to the bottle shoulder. In the present invention, the driving member 5 drives the lifting rod 3 to move upward, driving the bottle body 4 to rise. The bottle body 4 is inserted into the bottle pressing hole 10. The bottle body 4 drives the bottle pressing plate 9 to rise. The rising bottle plate drives the bottle pressing shaft 7 to rise, and the spring 8 is compressed. Correspondingly, the elastic force of the spring 8 makes the bottle shoulder and the bottle pressing hole 10 press tightly together, completing the bottle pressing action. After the capping head above the bottle body 4 moves downward to complete the capping action, the driving member 5 drives the lifting rod 3 to move downward, driving the bottle body 4 to descend, and the bottle body 4 is separated from the bottle pressing hole 10. The present invention completes the bottle pressing action by raising the bottle body 4 instead of lowering the bottle pressing plate 9, reducing the length of the lifting rod 3 and shortening its suspended portion. After long-term use, the structural rigidity of the lifting rod 3 can still be well maintained, ensuring that the bottle body 4 and the bottle pressing plate 9 are always coaxial during the bottle pressing process.

[0025] An embodiment of the driving member 5: the driving member 5 includes a cam 051 fixed on the frame 1, and a pulley 052 is rotatably provided at the lower end of the lifting rod 3. The pulley 052 rolls along the upper end of the cam 051, driving the lifting rod 3 to continuously rise and fall.

[0026] As another embodiment of the present invention: a positioning plate is fixed to the upper end of the lifting rod 3, and the positioning plate is used to place the bottle body 4. The lifting rod 3 drives the bottle body 4 to move up and down through the positioning plate.

[0027] A way to install the bottle pressing shaft 7: refer to the attached Figure 3 A bottle pressing sleeve 11 is fixed on the positioning plate 6, the bottle pressing shaft 7 is slidably arranged at the lower end of the bottle pressing sleeve 11, the upper end of the bottle pressing shaft 7 is arranged in the bottle pressing sleeve 11, and the two ends of the spring 8 are respectively connected to the bottle pressing sleeve 11 and the bottle pressing shaft 7.

[0028] One installation method of the spring 8: the upper end of the bottle pressing sleeve 11 is threadedly connected with a locking bolt 12, and the spring 8 is arranged between the locking bolt 12 and the bottle pressing shaft 7. In this structural design, it is convenient to adjust the pre-tightening pressure of the spring 8 by the locking bolt 12.

[0029] As another embodiment of the present invention, a convex ring 13 is fixed on the bottle pressing shaft 7, and a stop surface is provided in the bottle pressing sleeve 11 to cooperate with the convex ring 13, and the stop surface is located below the convex ring 13. The stop surface prevents the convex ring 13 from moving downward, thereby limiting the bottle pressing shaft 7 from sliding out from below.

[0030] As another embodiment of the present invention: a lower positioning column 14 is fixed to the upper end of the convex ring 13, and the lower positioning column 14 is inserted into the spring 8. This structure is convenient for installing the spring 8 and for positioning the spring 8.

[0031] An embodiment of the locking bolt 12: Figure 4 The locking bolt 12 includes an upper positioning post 0121 and a fixing plate 0122 fixed to the outside of the upper positioning post 0121. The fixing plate 0122 is disposed within the bottle pressing sleeve 11 and is threadedly connected to the bottle pressing sleeve 11. The lower end of the upper positioning post 0121 is inserted into the spring 8. This structure facilitates the installation of the spring 8, the positioning of the spring 8, and the adjustment of the preload pressure of the spring 8.

[0032] An implementation method for preventing the bottle pressing shaft 7 from rotating during the up and down movement: a guide pin 15 is provided on the bottle pressing shaft 7, and a guide groove is provided in the bottle pressing sleeve 11. When the bottle pressing shaft 7 is raised or lowered, the guide pin 15 slides up and down along the guide groove on the bottle pressing sleeve 11 to ensure that the bottle pressing hole 10 is always coaxial with the bottle body 4.

[0033] As another embodiment of the present invention: Figure 5 A positioning groove 16 is provided on the bottle pressing sleeve 11, and a positioning block adapted to the positioning groove 16 is provided on the positioning plate 6. When the bottle pressing sleeve 11 is installed on the positioning plate 6, the positioning block cooperates with the positioning groove 16 to facilitate the positioning of the bottle pressing sleeve 11, so that the bottle pressing hole 10 on the bottle pressing plate 9 is coaxial with the bottle shoulder.

[0034] One installation method of the positioning disc 6 is as follows: a hollow shaft 17 is fixed on the turntable 2 , and the positioning disc 6 is fixed on the hollow shaft 17 .
