This utility model relates to the field of pharmaceutical filling technology and discloses a quantitative filling device for ointments, including a transmission groove with a
conveyor belt inside; a rectangular frame with a guide rail at its front end and a filling
assembly at its front end; the filling
assembly includes a filling
nozzle, a filling hose, and a control box; a synchronous movement
assembly is provided between the filling
nozzle and the guide rail, the synchronous movement assembly including a moving part and a
servo motor, the moving part including a lead screw, a
locking plate, and a moving base. By setting the synchronous movement assembly, multiple sets of filling nozzles can complete filling while moving at the same speed as the filling
bottle, which can effectively improve filling efficiency. By setting a lifting unit, the height of the guide rail and the filling
nozzle can be adjusted synchronously, facilitating filling. By setting the connecting block and the
locking plate to have a movable
interlocking relationship, the device can be easily installed and disassembled, and subsequent maintenance and replacement are more convenient.
