Description

Technical Field

[0001] This utility model relates to the field of food and pharmaceutical packaging technology, and specifically to a capping device. Background Technology

[0002] Capping machines primarily cap bottles after the corks have been added. Existing capping machines typically consist of a cutting blade, a connecting shaft, and a mounting base. The cutting blade is mounted on the lower end of the connecting shaft via rolling bearings, while the upper end of the connecting shaft is fixedly mounted on the mounting base. Due to variations in bottle sizes and capping characteristics, the hardness and thickness of the aluminum cap significantly affect the sealing performance and appearance after capping. This type of capping device has the following shortcomings:

[0003] 1) When the aluminum cap is too long, the rolled cap needs more aluminum edging, but the rolled cap angle cannot be adjusted, which affects the appearance of the rolled cap;

[0004] 2) When the height of the bottle neck step, rubber stopper and aluminum cap combination is different for bottles of different specifications, it cannot be adjusted accordingly, which affects the quality of capping.

[0005] 3) When the aluminum cap is too short or too thick, the rolling cutter will experience a greater reaction force from the cap, which will affect the quality of the cap and the service life of the rolling cutter. Utility Model Content

[0006] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a capping device with adjustable capping angle, strong adaptability and good capping effect.

[0007] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0008] A capping device includes a mounting base, a connecting shaft, and a rolling cutter. The rolling cutter is rotatably mounted on one end of the connecting shaft, and the other end of the connecting shaft is elastically connected to the mounting base. The connecting shaft also abuts against the mounting base, and the abutting surface is an arc surface. The mounting base is provided with an angle adjustment mechanism for adjusting the angle of the connecting shaft, and the mounting base is provided with a clearance space to avoid changes in the angle of the connecting shaft.

[0009] As a further improvement to the above technical solution:

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0029] In this utility model, unless otherwise explicitly specified and limited, the terms "assembly," "connection," "joining," and "fixing" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0030] Figures 1 to 4 An embodiment of the capping device of this utility model is shown, such as Figure 1 and Figure 2As shown, the capping device of this embodiment includes a mounting base 1, a connecting shaft 2 and a rolling cutter 3. The rolling cutter 3 is rotatably mounted on one end of the connecting shaft 2, and the other end of the connecting shaft 2 is elastically connected to the mounting base 1. The connecting shaft 2 also abuts against the mounting base 1, and the abutting surface is an arc surface. The mounting base 1 is provided with an angle adjustment mechanism 4 for adjusting the angle of the connecting shaft 2, and the mounting base 1 is provided with a clearance space 5 to avoid changes in the angle of the connecting shaft 2.

[0031] The capping device has an arc-shaped contact surface between the connecting shaft 2 and the mounting base 1. The angle of the connecting shaft 2 can be adjusted by the angle adjustment mechanism 4, and the clearance space 5 can avoid changes in the angle of the connecting shaft 2, thereby adjusting the capping tilt angle of the capping blade 3. When the aluminum cap is too long, it can cap deeper and more edges, meet the appearance requirements of capping, ensure the capping effect, and improve the capping quality. At the same time, it can adapt to the capping angle requirements of different bottles, with high adaptability. In addition, the connecting shaft 2 and the mounting base 1 are elastically connected, so that the capping blade 3 has a certain amount of movement in the height direction, which can adapt to the capping of bottles with different bottle mouth heights and avoid bottle breakage.

[0032] Furthermore, in this embodiment, the angle adjustment mechanism 4 includes multiple elastic adjustment components 6, which are arranged circumferentially around the mounting base 1. Each elastic adjustment component 6 includes a first elastic element 61 and an adjusting element 62. One end of the first elastic element 61 is connected to the connecting shaft 2, and the other end is connected to the adjusting element 62. The adjusting element 62 is threadedly connected to the mounting base 1. Tightening the adjusting element 62 compresses the first elastic element 61, thereby pushing the connecting shaft 2 to deflect and achieving angle adjustment of the rolling cutter 3. Since multiple elastic adjustment components 6 are provided and arranged circumferentially around the mounting base 1, angle adjustment in multiple directions can be achieved. In addition, tightening the adjusting element 62 increases the clamping force of the rolling cutter 3, allowing the rolling cutter 3 to clamp thicker aluminum caps and ensuring the cap-clamping effect. Specifically, there are three elastic adjustment components 6. During adjustment, one component is kept stationary while the other two are adjusted according to the required adjustment angle. Preferably, the contact surface between the connecting shaft 2 and the mounting base 1 is spherical to accommodate multi-angle adjustment.

[0033] Furthermore, in this embodiment, multiple first limiting rods 21 are provided around the connecting shaft 2, and the first elastic members 61 are correspondingly sleeved on the first limiting rods 21. The first limiting rods 21 limit the extrusion direction of the first elastic members 61, which is beneficial to the accuracy of angle adjustment.

[0034] Furthermore, in this embodiment, the capping device also includes a pressure regulating component 7, which is used to adjust the capping force of the capping blade 3. It can adapt to bottles with different clamping force requirements, exhibiting good adaptability.

[0035] Furthermore, in this embodiment, the pressure regulating component 7 includes a second elastic element 72 and a first adjusting nut 73. The first adjusting nut 73 is threaded onto the connecting shaft 2, and the second elastic element 72 is sleeved on the connecting shaft 2 and located between the first adjusting nut 73 and the mounting base 1. During adjustment, the first adjusting nut 73 is first tightened, and the second elastic element 72 pulls the connecting shaft 2. Then, the capping angle and capping clamping force are adjusted through the angle adjusting mechanism 4. Since the capping blade 3 is tilted, when the clamping force is large, the downward axial force will also increase. At this time, the upward tension of the second elastic element 72 can cancel out the downward axial force, so that the capping blade 3 can press the edge upward to ensure sealing and adapt to bottles with different thicknesses and bottle mouth heights. In addition, the connecting shaft 2 is elastically connected to the mounting base 1 through the second elastic element 72, so that the capping blade 3 has a certain amount of movement in the height direction, which can adapt to bottles with different bottle mouth heights, realize fine adjustment of the blade height, and avoid bottle breakage.

[0036] Furthermore, in this embodiment, a protective cover 74 is detachably provided on the mounting base 1, and the protective cover 74 covers the pressure regulating component 7. This protects the pressure regulating component 7 and also improves the aesthetics.

[0037] Furthermore, in this embodiment, the capping device also includes a capping arm 8, with the mounting base 1 connected to the capping arm 8. The capping arm 8 is equipped with a height adjustment component 9 for adjusting the connection height of the mounting base 1. The height of the mounting base 1 is adjusted by the height adjustment component 9, thereby adjusting the capping height of the capping blade 3 to meet the capping requirements of bottles of different sizes.

[0038] Furthermore, in this embodiment, the height adjustment assembly 9 includes an adjusting screw 91, a third elastic element 92, and a second adjusting nut 93. The two ends of the adjusting screw 91 are connected to the rolling cutter arm 8 and the mounting base 1, respectively. The third elastic element 92 is located between the rolling cutter arm 8 and the mounting base 1 and is sleeved outside the adjusting screw 91. The second adjusting nut 93 is threaded to one end of the adjusting screw 91 and abuts against the outside of the rolling cutter arm 8. The other end of the adjusting screw 91 is provided with a limiting part 94, which abuts against the outside of the mounting base 1. Tightening the second adjusting nut 93 pulls the third elastic element 92, thereby increasing the height of the mounting base 1 and the rolling cap height; loosening it has the opposite effect. Simultaneously, the third elastic element 92 has a buffering effect on the reaction force borne by the rolling cutter 3.

[0039] Furthermore, in this embodiment, a connecting seat 11 is provided on one side of the mounting base 1, and the connecting seat 11 is connected to the rolling cutter arm 8. This facilitates the connection between the mounting base 1 and the connecting seat 11.

[0040] Furthermore, in this embodiment, the rolling cutter arm 8 is provided with a mounting hole 81 and an oblong hole 82 for adjusting the mounting angle of the rolling cutter arm 8. The rolling cutter arm 8 cooperates with an external mounting shaft through the mounting hole 81 and is connected to an external mounting bracket through the oblong hole 82. It should be equipped with a locking member for locking. The mounting angle can be adjusted by adjusting the locking position of the locking member and the oblong hole 82.

Any person skilled in the art can make many possible variations and modifications to the present invention, or modify it into equivalent embodiments, without departing from the scope of the present invention. Therefore, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention, without departing from the content of the present invention, should fall within the protection scope of the present invention.
