In this embodiment, when the container 30 is conveyed in a straight line to enter the filling station, the motor i 210 drives the pulley 209 to rotate, since the pulley 209 is engaged with the synchronous belt 208, and the synchronous belt 208 is fixed on the cross beam 205, the pulley 209 will roll along the synchronous belt 208, through the sliding fit of the inner carriage 207 and the guide rail i 206, the filling frame 200 will be driven by the motor i 210 to translate on the cross beam 205, the moving direction and the moving speed of the filling valve 204 are consistent with the conveying direction and the conveying speed of the container 30, so the filling valve 204 obtains the capability of moving synchronously with the container 30, when the container 30 is conveyed, the synchronous tracking mechanism 201 drives the filling valve 204 to translate synchronously in a horizontal direction along with the container 30, then the filling valve 204 will descend under the driving of the lifting mechanism 202 to abut against the container 30 to complete the filling operation, after the filling is completed, the lifting mechanism 202 lifts the filling frame 200 to make the filling valve 204 leave the container 30, the motor I210 rotates reversely to drive the filling frame 200 to move reversely and return to the initial position to prepare the next filling process, and the filling valve 204 is in butt joint with the container 30 in the synchronous movement process of the container 30 and completes the filling operation, so that the working mode of the whole filling device is continuous, and the production efficiency is improved. When the filling valve 204 needs to perform other processes, the station switching mechanism 203 drives the cross beam 205 to translate in the horizontal plane along the direction perpendicular to the arrangement direction of the filling valve 204, so that the filling valve 204 quickly leaves the filling station where the container 30 is located in the horizontal direction.
In addition, as shown in fig. 12, in order to increase the stability of the filling valve 204 when it is abutted against the container 30, a bottle mouth clamping assembly is further provided on the filling frame 200, the bottle mouth clamping assembly includes two oppositely arranged clamping plates 219, the clamping plates 219 are driven by an air cylinder, notches 220 are provided on the clamping plates 219, when the clamping plates 219 approach each other, the notches 220 are abutted to form a fixing structure for clamping the bottle mouth of the container 30, once the container 30 is clamped, the filling valve 204 is defaulted to be opposite to the bottle mouth of the container 30, and then the filling procedure can be executed.
In the initial state, the filling valve 204 is always above the conveyor belt and directly above the center lines of the two screws 101, so after the screws 101 are input into the container 30, the center lines of the screws 101, the container 30 and the filling valve 204 are all in the same vertical plane, and the filling valve 204 is driven by the synchronous tracking mechanism 201 and the lifting mechanism 202 to make a rotary motion in the vertical plane. As shown in fig. 13, the path indicated by the open arrows is the range in which the filling valve 204 is reset waiting to enter the filling state, and the path indicated by the solid arrows is the range in which the filling valve 204 enters the filling state. During the filling phase, the screw 101 is in continuous motion, i.e. the container 30 is in motion all the time. Because the filling valve 204 can translate, the capability of synchronous and co-directional movement with the container 30 is obtained, and the technical effect of synchronous tracking continuous filling is further obtained. Once the container 30 is full, the fill valve 204 is immediately raised, translated back, lowered, and filled.
