(1) arranging the sour milk bottles to be filled on the filling conveying plate in parallel, abutting against the fixed clamping plate, and then inserting the movable clamping plate on the filling conveying plate to enable the movable clamping plate and the fixed clamping plate to clamp the sour milk bottles; the controller is started, the motor is controlled by the controller to drive the transmission wheel to rotate, the filling transport plate is driven to transmit forwards through the friction plate, when the positioning hole moves between the light emitter and the light receiver, light rays emitted by the light emitter are received by the light receiver, the light receiver transmits signals to the controller, the controller receives the signals of the light receiver and then outputs instructions to control the motor to stop working, and the filling transport plate stops moving;
(2) the controller receives signals of the light receiver and simultaneously outputs instructions to the electric control lifter and starts timing, the electric control lifter is controlled to contract to drive the transverse plate to move downwards, when the transverse plate moves downwards to the conical surface at the bottom of the gun body to tightly press the bottle mouth, the time set by an internal program of the controller is reached, the electric control lifter is controlled to stop working by the controller at the moment, and simultaneously the instructions are output to the electric control air pump and the electric control switch to control the electric control air pump to start working, so that negative pressure is formed in the sour milk bottle, and the sour milk can be filled into the bottle more easily and more quickly; the electric control switch is controlled to be switched off, the coil is powered off, the magnetism disappears, the moving block moves downwards under the action of gravity, the stepped surface is separated from the conical surface, and the yoghourt flows into the liquid filling cavity from the fermentation tank through the hose, the guide pipe and the gap of the cross rod;
(3) at the moment, because the bottom surface of the liquid outlet cylinder is attached to the bottom surface of the liquid filling cavity, the yoghourt in the liquid filling cavity enters the liquid outlet cylinder from the liquid flowing hole, then enters the yoghourt bottle from the liquid outlet cylinder through the depth measuring tube for filling, and after the moving block moves downwards, the depth measuring tube also extends to the bottom position of the yoghourt bottle;
(4) when the yoghourt liquid level reaches a certain height, the controller controls the electric control air suction pump to stop working through information sent back by the wireless liquid level sensor, and controls the electric control switch to close and the controller to start timing at the same time, the coil is electrified to generate magnetism, and the permanent magnet is placed in the gap of the side wall of the liquid outlet cylinder, the magnetic attraction of the coil enables the moving block to integrally move upwards, the stepped surface is attached to the conical surface again, so that the yoghourt is prevented from flowing into the filling cavity from the guide pipe; when the liquid level of the yoghourt reaches the set height of the controller, the yoghourt bottle is not filled, and when the moving block moves upwards, the residual yoghourt in the liquid outlet cylinder continuously enters the yoghourt bottle from the depth measuring tube under the action of gravity to supplement the milk quantity in the yoghourt bottle;
