detailed description

In the following, the technical solutions in the embodiments of the present invention will be clearly and completely described with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

Example one

Please refer to FIGS. 1 to 4. In an embodiment of the present invention, an automatic capping device for a plastic container includes a cam divider 7. The divided output end of the cam divider 7 is fixed through the lower part of the casing. The plate 11 is fixed to the two-layer dial 14 connected by a support rod 18. The dial 14 at the upper end is fixed with an upper connecting plate 15 for receiving the turntable positioning plate 9 through another support rod 18. When the cam divider 7 When the driving dial 14 rotates, the upper connecting plate 15 and the turntable positioning plate 9 follow the rotation and cooperate with the friction of the lower fixing plate 11 to rotate and position the placed plastic container. The side end of the dial 14 is provided with a through connection The lever assembly drives the positioning buckle cap assembly moving up and down along the guide rail 4. The side end of the positioning buckle cap assembly is provided with a cover chute 20 for container lid placement, so that when the dial 14 transports the plastic container directly below the positioning buckle cap assembly At this time, the positioning buckle cap assembly is moved down to achieve secondary positioning, and at the same time, the container lid on the lid chute 20 is buckled at the buckle position of the plastic container, thereby completing the one-time buckle process with a high degree of automation.

During positioning, the plastic container rotates during rotation. At this time, the turntable positioning plate 9 fixed on the upper plate 15 passes under the characteristic position of the bottle mouth on the plastic container, and the handle position is The turntable positioning plate 9 blocks it so that it cannot rotate, thereby completing positioning.

The above-mentioned cam divider 7 is driven and rotated by a motor 8, and the motor 8 is fixed to the cam divider 7 through a motor base.

Specifically, the dial 14 is provided with a plurality of station opening slots, and each station slot corresponds to a turntable positioning plate 9 respectively.

It should be noted that during the entire operation of the device, all the actions are completed during the rotation of the cam divider 7 once. The number of stations of the cam divider 7 is the same as that of the dial 14. The division of the cam divider 7 is at a stationary stage. The opening slot of the dial 14 should be stopped at the place where the plastic container is placed and under the positioning buckle cover assembly.

The positioning buckle cover assembly includes a slide plate 13 slidably mounted on the guide rail 4. The lower end of the slide plate 13 is respectively fixed with a punch 5 and a pressing positioning plate 6. The punch 5 is used to buckle the container lid in the cover chute to plastic. The position of the lid of the container, and the positioning plate 6 for pressing down is used for secondary positioning of the handle position of the plastic container.

Specifically, the link assembly includes a cam divider sprocket 1, an eccentric sprocket 2, and a deflecting link 3. The cam divider sprocket 1 is fixed on an output shaft of the cam divider 7, and passes through a chain 16. It is rotatably connected with the eccentric sprocket 2 fixed on the sprocket shaft 12. The eccentric position of the eccentric sprocket 2 is rotatably connected with one end of the eccentric link 3. The other end of the eccentric link 3 is hinged on the slide plate 13. In the above, when the cam divider 7 rotates, the cam divider sprocket 1 is driven to rotate. The cam divider sprocket 1 drives the eccentric sprocket 2 to rotate through the chain 16. The eccentric sprocket 2 drives the slide plate 13 to and fro through the eccentric link 3. Moving up and down.

Example two

In the specific implementation process of the present invention, another embodiment is proposed to complete the application. Specifically, the lower fixing plate 11 is further provided with a rotating disk 19, which is located behind the positioning buckle cover assembly (here The rear refers to the direction opposite to the rotating direction of the dial 14). The plastic container is forcibly positioned when the rotating disk 19 is rotated to ensure the positioning effect.

It is obvious to a person skilled in the art that the present invention is not limited to the details of the above-mentioned exemplary embodiments, and the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention. Therefore, the embodiments are to be regarded as exemplary and non-limiting in every respect, and the scope of the present invention is defined by the appended claims rather than the above description, and therefore is intended to fall within the claims. All changes that are within the meaning and scope of equivalent elements are encompassed by the invention. Any reference signs in the claims should not be construed as limiting the claims involved.

In addition, it should be understood that although this specification is described in terms of embodiments, not every embodiment includes only an independent technical solution. This description of the specification is for clarity only, and those skilled in the art should take the specification as a whole. The technical solutions in the embodiments can also be appropriately combined to form other implementations that can be understood by those skilled in the art.
