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.

Second embodiment of the utility model:

based on the structure of the above embodiment, the difference lies in the driving unit, in this embodiment, the driving unit adopts an air cylinder or an electric cylinder, the output end of the air cylinder or the electric cylinder is connected with the corresponding sliding base 111, and the air cylinder or the electric cylinder respectively drives the two sliding bases 111 to move close to or away from each other relative to the same central line. Although the form of the driving unit is different, the movement mode of the final driving screw 101 is consistent, and the two screws 101 can be driven to move reversely and synchronously in a parallel state, so that the distance between the two screws 101 is adjusted, and the size of the grouping area 105 and the size of the calling area 106 are adjusted to adapt to containers of different bottle types.

Third embodiment of the utility model:

the filling material may form a residue in the line of the filling valve 204, and in order to remove the residue, a cleaning mechanism 40 is provided on one side of the grouping device 10 in the present embodiment, as shown in fig. 1. During cleaning, the station switching mechanism 203 carries the filling valve 204 from the filling station to the cleaning station, and the lifting mechanism 202 lowers the filling valve 204 to be aligned and communicated with the cleaning connecting piece in the cleaning mechanism 40, so that the cleaning process can be performed on the filling valve 204.

The above embodiments are only for further illustration of the present invention, and should not be construed as limiting the scope of the present invention, and the technical engineers in the art can make insubstantial modifications and adaptations of the present invention based on the above disclosure and disclosure of the utility model.
