[0004] Regarding the above-mentioned prior art, the inventor believes that there are still the following defects to be solved:

[0005] Since the bottle caps are conveyed by a conveyor belt, during use, not only does it require manually placing the bottle caps into the placement groove for objects to be pressed, but also the gaskets need to be placed at the mouth of the plastic bottle caps. However, the continuous rolling of the conveyor belt makes these operations difficult to perform. Therefore, the inventor believes that the existing pressing devices for bottle cap gaskets still need to be improved. Summary of the Utility Model

Specific implementation mode

[0023] The following combines the attached Figures 1-5 Further detailed description will be made on the specific implementation mode of the present utility model.

[0024] Embodiment 1

[0025] A gasket pressing device for plastic bottle cap processing includes a base 10, and a gasket pressing mechanism 20 is provided on the base 10. The gasket pressing mechanism 20 is used to press the gasket placed at the mouth of the bottle cap into the bottle cap. This is the prior art and will not be elaborated here.

[0026] In this embodiment, a rotating tabletop 30 is rotatably provided on the base 10. A transmission groove 31 is provided on the surface of the rotating tabletop 30. The transmission groove 31 is concentric with the rotating tabletop 30, and a plurality of object-to-be-pressed placement plates 40 are movably provided in the transmission groove 31. An object-to-be-pressed placement groove 41 is provided on the surface of the object-to-be-pressed placement plate 40. A connection structure 50 is connected between the object-to-be-pressed placement plate 40 and the transmission groove 31. When the rotating tabletop 30 rotates, the object-to-be-pressed placement plate 40 is driven to move synchronously through the connection structure 50. The object to be pressed is the bottle cap and the gasket placed at the mouth of the bottle. When in use, the bottle cap with a gasket at its mouth is placed in the object-to-be-pressed placement groove 41. When the rotating tabletop 30 rotates on the surface of the base 10, the object-to-be-pressed placement plate 40 is driven to rotate through the connection structure 50, thereby driving the bottle cap with a gasket at its mouth to rotate together. When the bottle cap with a gasket at its mouth moves to the gasket pressing mechanism 20, the gasket is pressed into the bottle cap through the gasket pressing mechanism 20. It can be understood that the movement of the object-to-be-pressed placement plate 40 is mainly through the transmission of the connection structure 50. Therefore, when it is necessary to place the bottle cap into the object-to-be-pressed placement groove 41, the transmission of the connection structure 50 can be released, so that the object-to-be-pressed placement plate 40 stops moving. In this way, the object-to-be-pressed placement plate 40 that has not released the transmission of the connection structure 50 continues to move to the gasket pressing mechanism 20, while the object-to-be-pressed placement plate 40 that has released the connection structure 50 can temporarily stop moving, facilitating the placement or removal of the bottle cap.

[0027] In this embodiment, the connection structure 50 includes a fixed block 51A fixed on the rotating table 30 and a connection bolt 52A threadedly connected to the fixed block 51A. A connection groove is provided on the side surface of the object-to-be-pressed placement plate 40. During use, by rotating the connection bolt 52A, the connection bolt 52A is inserted into the connection groove, and thus the connection between the object-to-be-pressed placement plate 40 and the rotating table 30 can be realized, and the movement of the object-to-be-pressed placement plate 40 can be achieved. Conversely, by removing the connection bolt 52A from the connection groove of the object-to-be-pressed placement plate 40, the transmission can be released.

[0028] Although the connection structure 50 is released, under the action of friction, the object-to-be-pressed placement plate 40 will still move together with the rotating table 30, which will also affect the placement of the bottle caps and gaskets. To solve this problem, a stop mechanism 70 is provided on the base 10. The stop mechanism 70 includes a stop plate 71 fixed on the base 10 and a stop bolt 72 threadedly connected to the stop plate 71. After the connection structure 50 is released, the stop bolt 72 can be rotated and inserted into the connection groove on the side surface of the object-to-be-pressed placement plate 40. In this way, other object-to-be-pressed placement plates 40 move with the rotating table 30, and the object-to-be-pressed placement plate 40 connected to the stop mechanism 70 is connected to the base 10 and completely stops.

[0029] In some embodiments, the rotating table 30 is a ring structure, and a driving mechanism 60 is provided between the rotating table 30 and the base 10. The driving mechanism 60 includes a motor 61 fixed to the base 10, a gear 62 fixed to the output shaft of the motor 61, and a gear ring 63 fixed to the rotating table 30. The gear 62 is meshed and connected to the gear ring 63. During use, the external power supply of the motor 61 is turned on, the output shaft of the motor 61 drives the gear 62 to rotate, the gear 62 drives the gear ring 63 to rotate, and the gear ring 63 drives the rotating table 30 to rotate.

[0030] Rollers 42 are installed at the bottom of the object-to-be-pressed placement plate 40.

[0031] An annular rotating groove 11 is provided on the surface of the base 10, and the rotating table 30 is rotatably installed in the rotating groove 11.

[0032] Furthermore, an induction device is provided on the gasket pressing mechanism 20. When the induction device senses that the bottle cap with the pre-placed gasket just reaches directly below the gasket pressing mechanism 20, the motor 61 stops rotating. The induction device can be an infrared sensor and other existing technologies. For existing technologies, reference can be specifically made to the Chinese utility model patent bottle cap gasket pressing device with the application number 201921854860.6, which will not be elaborated here.

[0033] Embodiment Two

[0034] Embodiment 2 has substantially the same structure as Embodiment 1, except that: the connection structure 50 includes a damping structure 51B connected between the object-to-be-pressed placement plate 40 and the rotating tabletop 30.

[0035] In Embodiment 1, when the object-to-be-pressed placement plate 40 that is active in the front is fixed to the base 10 through the stop mechanism 70, if the staff does not place the bottle cap well and release the limit of the stop mechanism 70 on the object-to-be-pressed placement plate 40 within a certain time, then when the object-to-be-pressed placement plate 40 in the rear moves following the rotating tabletop 30, it may be blocked by the object-to-be-pressed placement plate 40 in the front. In this case, the rotating tabletop 30 cannot rotate normally, which is likely to cause the motor 61 to burn out. To prevent this situation from occurring, we propose the second embodiment of the connection structure 50. In Embodiment 2, the connection structure 50 is a damping structure 51B provided between the object-to-be-pressed placement plate 40 and the rotating tabletop 30. The damping structure 51B can be a friction block fixed to the bottom of the object-to-be-pressed placement plate 40. The friction block is in close contact with the rotating tabletop 30. Through the frictional force, the rotating tabletop 30 can drive the object-to-be-pressed placement plate 40 to move synchronously. When one of the object-to-be-pressed placement plates 40 is locked by the stop mechanism 70, although the object-to-be-pressed placement plate 40 in the rear will be blocked, it will not cause the rotation of the rotating tabletop 30, thereby preventing the motor 61 from burning out.

[0036] For a gasket pressing device for plastic bottle cap processing of the present utility model, a plurality of object-to-be-pressed placement plates 40 are connected to the rotatable rotating tabletop 30 through the connection structure 50. The bottle caps with gaskets placed at their mouths are sent one by one under the gasket pressing mechanism 20 through the rotation of the rotating tabletop 30 for pressing. Moreover, by disassembling the connection structure 50, the object-to-be-pressed placement plate 40 can be separated from the rotating tabletop 30. After the object-to-be-pressed placement plate 40 separated from the rotating tabletop 30 is limited by the stop mechanism 70, the bottle cap and the gasket can be stably placed in the object-to-be-pressed placement groove 41 without affecting the feeding of other object-to-be-pressed placement plates 40 to the gasket pressing mechanism 20.

[0037] Finally, it should be noted that: the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
