Automatic filling equipment

The utility model discloses automatic filling equipment, belongs to the technical field of filling machinery and aims to solve the problems of unstable running, low automation degree and the like of a filling box body driving mechanism in the prior art. The automatic filling equipment comprises a cam driving mechanism, a filling amount adjusting mechanism, a filling control mechanism and a filling executing mechanism, wherein an output shaft of a plunger cam is directly connected with an output shaft of a main power motor to provide power for a cam moving rod; the other end of a power arm is combined with a hook in the filling control mechanism to control whether the action of filling is performed or not; a linking block can rotate around an axial hole of an adjusting bolt and is linked with a screw threaded rod of an adjusting rod through threads; a sensor is used for sending a filling signal to control an air cylinder to extend out; and a plunger control rod rotates around a control rod shaft and drives a piston to reciprocate. The stability of filling amount and the accuracy of filling are ensured through adjustment of a stepping motor. The automatic filling equipment is compact in structure, high in execution precision and high in automation degree and facilitates the realization of high-speed automation.
