[0002] Existing filling and feeding devices are prone to poor operational stability, high failure rate, and insufficient material feeding leading to leakage when feeding three types of materials alternately or simultaneously. Summary of the Invention

[0003] The purpose of this invention is to address the shortcomings of existing technologies by proposing a filling and pushing device and a mechanism having a filling and pushing device.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a filling and pushing device, comprising a frame, a servo motor, a filling nozzle assembly, a three-color feed pipe, a three-color filling pump assembly, a rotary valve, a rotary valve cam, and a rotary valve switch rod assembly. The filling nozzle assembly is provided at the upper end of the frame. One side of the filling nozzle assembly is a filling nozzle, and the other side of the filling nozzle assembly is connected to the discharge end of three rotary valves. The upper ends of the three rotary valves are respectively connected to the corresponding three-color feed pipes. The three rotary valves are connected to the rotary valve cam through the rotary valve switch rod assembly. The rotary valve cam drives the rotary valve to connect with the three-color feed pipe. The rear ends of the three rotary valves are correspondingly connected to the three-color filling pump assembly. The driving part of the three-color filling pump assembly is driven by a servo motor, so that the three-color filling pump assembly drives the material in the corresponding rotary valve to be ejected from the filling nozzle of the filling nozzle assembly.

The rear end of the housing has a first connection port, the lower front side of the housing has a sloped discharge end, and the upper end of the housing has a feed port. The rear end of the inner liner is rotatably and sealingly connected to the first connection port. The rotary valve core is mounted on the rotary valve seat. The front end of the inner liner is connected to the rotary valve core and is rotated and sealed by the rotary valve seat. The rotary valve shaft passes through the housing and the rotary valve seat and is connected to the rotary valve core.
