Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] The technical solution of the present utility model is described in detail below in conjunction with the specific drawings.

The power assembly 4 provides power for the thrust plate assembly 6. Under the action of the thrust plate assembly 6, the lifting screw assembly 5 moves up and down, and the lifting screw assembly 5 drives the cover-screwing mechanism 3 to move up and down. The other side of the power assembly 4 is connected to the cam divider 9 through a gear, and the cam divider 9 is connected to the dial assembly 7. The cam divider 9 drives the dial assembly 7 to rotate intermittently through the interaction between the conjugate cam on the input shaft and the dividing plate of the needle bearings evenly distributed on the output shaft, as well as the design of the curved segments and straight segments of the cam.

[0032] The capping mechanism 3 includes a sliding base plate 301, a capping head 302, a first motor 303, a first linear bearing 304, and a belt transmission assembly 305. The capping head 302 is mounted on the bottom surface of the sliding base plate 301 through a support rod 306 and fixed by a bolt assembly. The capping head 302 is mounted on the bottom surface of the sliding base plate 301 through a head pulley seat and fixed by a head pulley shaft bushing and a bolt assembly. The first linear bearing 304 is mounted on the diagonal line of the sliding base plate 301. The first motor 303 is driven by a belt transmission assembly 305. 5 is connected to the capping head 302 and drives the capping head 302 to rotate; the belt drive assembly 305 includes a driving wheel, a driven wheel and a transmission belt. The driving wheel starts to rotate through the first motor 303. Since there is static friction between the driving wheel and the transmission belt, the rotation of the driving wheel will cause the transmission belt to start moving. At the same time, static friction will also be generated between the transmission belt and the driven wheel. This static friction becomes the driving force for the driven wheel to rotate. When the first motor 303 is started, its rotation is transmitted to the head pulley through the driving wheel and the transmission belt, thereby driving the capping head 302 to rotate. In a specific embodiment, the driving wheel is an O-type V-belt pulley with an outer diameter of 80-, and the transmission belt is an O-type 835 long triangle belt.

[0036] The lifting screw assembly 5 includes a lifting screw 501, a sleeve 502 and a floating joint 503. The sleeve 502 cooperates with the lifting screw 501. The floating joint 503 is fixed to the center of the sliding base plate 301 through a thread. The lower end of the lifting screw 501 is connected to the upper end of the second optical axis 604 through a thread. When the eccentric wheel 10 rotates, it drives the thrust plate assembly 6 to move up and down, and then drives the lifting screw assembly 5 to move up and down, thereby driving the screw capping mechanism 3 to move upward or downward, so that the screw capping head 302 is close to or away from the bottle mouth.

[0037] The dial assembly 7 includes a dial shaft 701 with a dial connected to the upper end thereof, the dial including a dial upper plate 702 and a dial lower plate 703, the two dials being fixed to the dial shaft 701 through a dial support rod 704 and a dial pressure plate 705, forming a stable dial structure.

The clutch power axle 708 is provided with a spring 709 on the outside to ensure the close contact between the clutch flywheel 707 and the clutch power axle 708, thereby ensuring the reliability and stability of the power transmission. The lower end of the clutch power wheel shaft 708 is connected to the cam divider 9.

[0038] In order to prevent the wine bottles from falling off the conveying mechanism 2 when the capping machine is working, a guard plate 11 is provided on the side of the dial close to the conveying mechanism 2.

[0039] The following is a detailed description of the operation of the above-mentioned single-head automatic capping machine:

[0040] The conveying mechanism conveys the filled and capped products to the dial of the equipment and stacks a certain number of bottles. There are 12 notches (stations) of corresponding bottle sizes and shapes on the dial assembly. The rotation of the dial is driven by the output shaft of the cam divider. After each rotation of a station, it stops at a rotation angle (relative to the input shaft). During the stop process, the capping mechanism is pressed down by the reducer, eccentric wheel, and connecting rod, and is lifted up after the capping is completed. When the capping mechanism is lifted to a certain height and detached from the bottle, the cam divider enters and rotates to a station again, allowing the next product to enter the capping station; when the capped product rotates to the subsequent conveying mechanism, it is sent away by the conveying mechanism to enter the post-process, and the cycle is repeated, thus completing the automatic capping of the product.

[0041] The serial numbers of the embodiments of the present application are only for description and do not represent the advantages and disadvantages of the embodiments. The above are only preferred embodiments of the present application, and do not limit the patent scope of the present application. Any equivalent structure or equivalent process transformation made by using the contents of the present application specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present application.
