[0005] The main object of the present invention is to provide an automatic filling and sealing machine, which can effectively solve the problems in the background art.

[0006] To achieve the above object, the technical solution adopted by the present invention is as follows: An automatic filling and sealing machine includes a conveying mechanism, and a feeding device, a filling device, a disinfection and sterilization device, a heat-sealing and film-covering sealing device, and a discharging device arranged in sequence along the conveying direction of the conveying mechanism. The feeding device is used for feeding empty containers and transferring them onto the conveying mechanism. The conveying mechanism transports the empty containers to the filling device for liquid filling. The conveying mechanism transports the liquid-filled containers to the heat-sealing and film-covering sealing device for heat-sealing a film at the opening of the container. Finally, it is transported to the discharging device by the mechanism and discharged through the discharging device. The feeding device includes a material feeding mechanism and an automatic box dropping mechanism. The material feeding mechanism includes a vibrating disk and its material transmission assembly. The material transmission assembly includes a transmission guide rail. The starting end of the transmission guide rail is connected to the discharging end of the vibrating disk. A defective product pushing assembly is arranged in the middle section of the transmission guide rail. The end of the transmission guide rail is arranged above the conveying mechanism and is provided with a material pushing assembly to push the material into the container on the conveying mechanism. The automatic box dropping mechanism is fixedly arranged at the starting end of the conveying mechanism. The automatic box dropping mechanism includes a motor, a plurality of synchronous belt wheels, a synchronous belt cooperating with the plurality of synchronous belt wheels, and a plurality of lower box wheels. The lower box wheels and the synchronous belt wheels are installed on the same shaft. A space is formed between the plurality of lower box wheels for accommodating the containers. The motor drives the synchronous belt to move, thereby driving the synchronous belt wheels cooperating with the synchronous belt and the lower box wheels connected to the synchronous belt wheels to rotate. As the lower box wheels rotate, the lowermost box located between the lower box wheels is pulled down by the rotation of the lower box wheel teeth.

[0007] As a further improvement, the filling device includes a liquid filling mechanism. The liquid filling mechanism is arranged above the conveying mechanism. The liquid filling mechanism includes a liquid filling cavity. The liquid filling cavity is connected to a liquid injection gun through a catheter. The liquid injection gun injects the liquid into the container.

[0008] As a further improvement, the disinfection and sterilization device is arranged above the conveying mechanism, between the filling device and the heat-sealing and film-covering sealing device.

[0009] As a further improvement, a box scraping assembly is further arranged at the front end of the heat-sealing and film-covering sealing device. The box scraping assembly includes a mounting frame installed on the conveying mechanism. A driving source is fixedly arranged at the upper end of the mounting frame. The output end of the driving source is provided with a box scraping fixing plate. A plurality of rotating motors are arranged on the box scraping fixing plate. The output end of the rotating motor passes through the box scraping fixing plate to set a first rotating gear. A plurality of second rotating gears are arranged at the lower end of the box scraping fixing plate and form a rotating slideway with the first rotating gear through a chain. A plurality of box scraping blades are evenly arranged on the rotating slideway. The box scraping blades abut against the edge of the container on the conveying mechanism.

[0010] Compared with the prior art, the present invention has the following beneficial effects: The automated assembly line design ensures the effective operation of the feeding device, filling device, disinfection and sterilization device, heat sealing and laminating device, and discharging device without any other complex operations. By using a motor to control the box dropping wheel, it has high running accuracy and a fast box dropping speed, reaching 12,000 per hour. By adjusting the configuration of the box dropping wheel, it can meet various boxes or cups with different cup mouth shapes, improving its application breadth. Since it does not use air pressure to push, it avoids bringing air pollution. The box dropping wheel has a spiral inclined plane, so it has a downward driving force on the box or cup, giving the box or cup a certain initial velocity when falling, so that the falling speed is much greater than free fall, greatly improving the box dropping speed. By setting the box scraping component, it effectively avoids the problem of air leakage in heat sealing and laminating due to material dropping on the side of the container.
