[0105] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. The description of the at least one exemplary embodiment is actually only illustrative, but not as any limitation on the present application and its application or use. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without any creative work, fall within the scope of protection of the present application.

[0106] As Figure 1 and Figure 2As shown, this embodiment of the invention provides a bottle cap opening and closing device, which includes a base 10, a bottle body clamping mechanism 20, a first buffer mechanism 30, a bottle cap clamping mechanism 40, and a rotary drive mechanism 50. The bottle body clamping mechanism 20 is rotatably mounted on the base 10 and is used to clamp the bottle body. The first buffer mechanism 30 is disposed between the bottle body clamping mechanism 20 and the base 10. The bottle cap clamping mechanism 40 is disposed opposite to the bottle body clamping mechanism 20 and is used to clamp the bottle cap. The rotary drive mechanism 50 is drivenly connected to the bottle body clamping mechanism 20, and drives the bottle body clamping mechanism 20 to rotate relative to the bottle cap clamping mechanism 40, so that the bottle body and the bottle cap are tightened or opened relative to each other.

[0107] The technical solution provided by this invention uses a bottle body clamping mechanism 20 to clamp the bottle body and a bottle cap clamping mechanism 40 to clamp the bottle cap. A rotary drive mechanism 50 drives the bottle body clamping mechanism 20 to rotate, causing the bottle body to rotate relative to the bottle cap. Furthermore, the first buffer mechanism 30 prevents the bottle body and bottle cap from being screwed too tightly, thus avoiding damage. In the process of opening or tightening the bottle cap, the bottle body clamping mechanism 20 applies rotational force to the bottle body. Compared to the conventional method where the bottle cap clamping mechanism 40 applies rotational force to the bottle cap, this method provides greater torque, facilitating the opening or tightening of the bottle cap.

[0108] like Figures 3 to 5 As shown, the bottle clamping mechanism 20 includes a support base 21, a drive mechanism, a first clamping assembly 22, a second clamping assembly 23, and a second buffer mechanism. The drive mechanism is mounted on the support base 21. The first clamping assembly 22 and the second clamping assembly 23 are disposed opposite each other on the support base 21. The drive mechanism is driven to the first clamping assembly 22 and / or the second clamping assembly 23, driving the first clamping assembly 22 and / or the second clamping assembly 23 to move. The first clamping assembly 22 and the second clamping assembly 23 cooperate to clamp the bottle. The first clamping assembly 22 and / or the second clamping assembly 23 are provided with the second buffer mechanism.

[0109] The bottle is placed between the first clamping component 22 and the second clamping component 23, and the bottle is clamped by the cooperation of the first clamping component 22 and the second clamping component 23. Since at least one of the first clamping component 22 and the second clamping component 23 is provided with a second buffer mechanism, when the bottle is clamped, the clamping component with the second buffer mechanism can pre-compress the bottle, avoiding excessive pressure on the bottle and reducing the clamping force exerted on the bottle, thereby reducing the possibility of damage to the bottle due to excessive clamping force. Simultaneously, the drive mechanism is connected to at least one of the first clamping component 22 and the second clamping component 23, enabling automatic clamping of the bottle and improving the convenience of bottle clamping.

[0110] In the embodiment, the second buffering mechanism comprises a first buffering assembly 24, and the first clamping assembly 22 comprises a first connecting portion 221 and a first bottle body clamping portion 222. The first connecting portion 221 is arranged on the support seat 21. The first bottle body clamping portion 222 is arranged on the side of the first connecting portion 221 close to the second clamping assembly 23. The first buffering assembly 24 is arranged between the first connecting portion 221 and the first bottle body clamping portion 222, and the first bottle body clamping portion 222 is movable relative to the first connecting portion 221 through the first buffering assembly 24. When the bottle body is clamped, the first bottle body clamping portion 222 abuts against the bottle body, and the bottle body generates a certain acting force on the first bottle body clamping portion 222. Under the action of the buffering assembly, the first bottle body clamping portion 222 has a tendency to move away from the bottle body, and moves away from the bottle body to avoid over-pressing the bottle body and to avoid or reduce the situation of clamping the bottle body.

[0143] According to the technical scheme, the bottle cap clamping mechanism 40 is provided with the first clamping jaw assembly and the second clamping jaw assembly, when clamping the bottle cap, the first clamping jaw assembly or the second clamping jaw assembly can be selected to clamp the bottle cap according to the type of the bottle cap or the specific scene where the bottle cap is located. Compared with the traditional technical scheme, in the present scheme, the first clamping jaw assembly and the second clamping jaw assembly are driven by the third driving member 42, so that the number of driving members is reduced, the size of the bottle cap clamping mechanism 40 is reduced, and the weight and cost of the bottle cap clamping mechanism 40 are reduced. Moreover, the first clamping jaw assembly and the second clamping jaw assembly can independently perform clamping actions, which facilitates clamping different types of bottle caps and expands the application range of the bottle cap clamping mechanism 40.

[0144] The structure of the first clamping jaw assembly and the structure of the second clamping jaw assembly can be the same or different. In the present scheme, the structure of the first clamping jaw assembly and the structure of the second clamping jaw assembly are different. In this way, the bottle cap clamping mechanism 40 can take different types of bottle caps, further improving the application scenarios of the bottle cap clamping mechanism 40 and expanding the application range of the bottle cap clamping mechanism 40.

In the present scheme, the machine body 41 extends in the vertical direction, and the first clamping jaw assembly and the second clamping jaw assembly are respectively located on the two sides of the machine body 41 which are oppositely arranged. In this way, the first clamping jaw assembly and the second clamping jaw assembly can avoid mutual interference when working, which improves the flexibility of the bottle cap clamping mechanism 40. Further, at least one of the first clamping jaw assembly and the second clamping jaw assembly is adjustable relative to the position of the machine body 41. In the present embodiment, the position of the second clamping jaw assembly relative to the machine body 41 is adjustable. When clamping the bottle cap by the second clamping jaw assembly, the second clamping jaw assembly is adjusted to a suitable position, then the bottle cap is clamped by the second clamping jaw assembly, and after clamping is completed, the position of the second clamping jaw assembly can be adjusted again as needed to complete the overall clamping action. In this way, the flexibility of the bottle cap clamping mechanism 40 can be further improved, the use range thereof is expanded, and the opening and tightening of the bottle cap are facilitated.

When clamping the bottle cap, the plurality of first bottle cap clamping portions 43 of the first clamping jaw assembly are close to the clamped bottle cap until the plurality of first bottle cap clamping surfaces are in abutment with the bottle cap. The plurality of clamping portions can clamp bottle caps of different sizes and shapes, thereby improving the adaptability of the first clamping jaw assembly.

[0146] Specifically, the contact area between the first bottle cap clamping surface of the first bottle cap clamping portion 43 and the bottle cap is located on the curved surface or the plane of the first bottle cap clamping surface, or the contact area between the first bottle cap clamping surface of the first bottle cap clamping portion 43 and the bottle cap has a plurality of contact areas, and the plurality of contact areas form an included angle with each other at the part on the first bottle cap clamping surface.

In this embodiment, the first clamping jaw assembly comprises the second anti-slip structure 431, and the second anti-slip structure 431 is a second anti-slip pattern, which is arranged on the first bottle cap clamping surface, and the second anti-slip pattern is a vertically arranged stripe structure.

[0149] Specifically, the second jaw assembly comprises a plurality of clamping rods 44 that cooperate to clamp the bottle cap. In this embodiment, the extension direction of the clamping rod 44 is the vertical direction, and the plurality of clamping rods 44 are annularly distributed. When the bottle cap is clamped by the second jaw assembly, the third driving member 42 drives the plurality of clamping rods 44 to approach the bottle cap until the plurality of clamping rods 44 are all in abutment with the bottle cap, completing the clamping of the clamped bottle cap. In this way, the contact area between the clamping rod 44 and the bottle cap can be increased, and the stability of the second jaw assembly in clamping the bottle cap is improved. Furthermore, in this way, the plurality of clamping rods 44 are reasonably distributed, which can reduce the space occupied by the second jaw assembly, facilitate the extension of the plurality of clamping rods 44 into the outer periphery of the bottle cap, and clamp the bottle cap, thereby improving the flexibility of clamping the bottle cap.

[0150] As shown in Figures 9 to 13 the clamping rod 44 comprises a first clamping section having a second bottle cap clamping surface for clamping the bottle cap. The second bottle cap clamping surface of at least one clamping rod 44 is a plane or an arc surface.
