[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] As shown in the figure, this utility model discloses a bottle cap guiding mechanism, including a fixing plate 1, a spring sheet 3, and a mounting ring 2. The mounting ring 2 includes an annular portion 21, a connecting portion 22, and a spring sheet retaining block 23. The connecting portion 22 is connected to the bottom of the annular portion 21. The spring sheet retaining block 23 is circumferentially mounted on the outside of the annular portion 21. The spring sheet 3 passes through the gap between the two spring sheet retaining blocks 23. The fixing plate 1 presses on the mounting ring 2. The top of the fixing plate 1 is flush with the top of the mounting ring 2, and the bottom of the fixing plate 1 is flush with the bottom of the mounting ring 2. The fixing plate 1 and the mounting ring 2 are connected by multiple fasteners.

[0033] In the initial position, the spring plate 3 is deformed into a 35° inward state with the vertical line. The cap assembly C, carrying the cap D, descends with the cam E. When the cam E reaches the 93.5° position, the cap D contacts the spring plate 3. Subsequently, the cap D and the spring plate 3 remain in contact and move downward synchronously. During this period, the position of the spring plate D3 remains unchanged. After the cam reaches the 130° position, the present invention begins to detach from the cap guide seat and move downward (the cap and the spring plate remain in contact). When the cam reaches the 180° position, the present invention detaches from the cap, and the spring plate returns to its upright state due to elasticity. When the cam reaches the 190° position, the pressure head presses down to complete the capping action. Then, the present invention continues to move upward to return to the initial position to receive the next set of caps. Returning to the initial state also avoids interference with the listening device and affects the listening process.

[0034] The process of attaching the cover in this utility model:

[0035] Status awaiting cover acceptance: such as Figure 10 Relying on the physical constraint of the cap guide seat F, the spring plate 3 maintains a certain inward state, forming an annular lifting space slightly smaller than the inner diameter of the cap.

[0036] Cap holding: When the bottle cap is delivered to the correct position, the spring plate 3 contacts the bottle cap and moves downwards synchronously.

[0037] Cap release: The device carries the bottle cap down to the bottle mouth and completes the capping action; when the bottle cap touches the bottle mouth 2mm away, the spring plate 3 disengages from the bottle cap, the spring plate 3 actively opens and disengages from the bottle cap, and resets to receive the next set of caps.

[0038] In one embodiment of this utility model, the spring plate retainer 23 is located at the upper outer side of the annular portion 21. This allows other parts to be installed at the lower end of the spring plate retainer 23.

The bottom of the spring sheet 3 is located in the mounting space A between the surface 221, the clearance groove 101 and the annular portion 21. The mounting space A is used to install the bottom of the spring sheet 3.

[0040] In one embodiment of this utility model, the spring sheet 3 has a bent structure. The spring sheet 3 includes a horizontal sheet 31 and a vertical sheet 32. The horizontal sheet 31 is located at the bottom and faces the fixing plate 1. The vertical sheet 32 ​​passes through the gap between the two spring sheet clips 23. In this way, the bottom of the entire spring sheet 3 is fixed, the upper end is used to guide the cover, and the vertical sheet 32 ​​of the spring sheet 3 can be deformed.

[0041] In one embodiment of this utility model, a spring ring 4 is also included. The spring ring 4 is located at the mounting space A, with its inner side contacting the outer side of the vertical piece 32 and its bottom contacting the top of the horizontal piece 31. The spring ring 4 is used to fasten the horizontal piece 31 of all the spring pieces 3 and to mount the spring pieces 3.

[0042] In one embodiment of the present invention, the fixing plate 1 is provided with a slot that matches the spring plate block 23 at the position facing the spring plate block 23, and the top of the spring plate block 23 is inclined downward.

[0043] In one embodiment of this utility model, a fixing connecting plate 102 is provided on one side of the fixing plate 1, and a fixing connecting hole 1021 is provided at the fixing connecting plate 102.
