as shown in figure 4, before the material box is pushed onto the weighing module, the weighing seat is in a state of being close to each other under the pushing of the air cylinder, and the weighing modules on the weighing seat are close to each other at the moment and form an integral weighing platform structure, so that the material box is pushed onto the weighing modules.

As shown in figure 5, after six magazines are pushed up to the weighing module, the six magazines are in a mutual abutting state, in order to ensure that the weighing modules are not influenced by the magazines which are close to each other or are mutually overlapped at the edge part, the weighing seat pulls open the weighing seat which is close to the weighing seat under the contraction of the cylinder, the weighing seat drives the magazines which are placed on the weighing modules to be separated from each other, and the mutual influence among the magazines in the weighing process is avoided.

And the weighing module independently weighs each material box, transmits the data to the PLC for processing, and performs different feeding filling on each material box according to the data processed by the PLC until the specified precision requirement is met.

And finally, after filling, the air cylinder is pushed out to drive the movable weighing seat to move along the movable guide rail, so that the movable weighing seat and the corresponding material box are brought back to a close state, and the material box is conveniently discharged after material supplementing and filling.

A filling method adopting the online weighing filling machine specifically comprises the following steps:

firstly, a plurality of material boxes are sent to a main filling area for filling simultaneously, and the filling amount of all the material boxes is lower than the standard filling amount.

And then, conveying the plurality of cartridges subjected to primary filling to a weighing and feeding filling area for feeding filling, weighing the cartridges by a weighing module before feeding filling, controlling a feeding filling machine to perform different feeding filling on the cartridges according to the weighed data, driving the weighing modules to be separated from each other by a weighing seat moving mechanism when the cartridges are weighed, and enabling the cartridges placed on the weighing modules not to influence each other in the weighing process.

And finally, extruding the material box after the material supplementing filling by the material box after the initial filling under the action of a box pushing mechanism to obtain a weighing material supplementing filling area, so as to realize continuous production, conveying the material box after the two times of filling to a post-process by a filled material box conveyor, and leaving the material box after the initial filling in the weighing material supplementing filling area for weighing and material supplementing filling.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents and improvements made within the spirit and principle of the present invention are intended to be included within the scope of the present invention.
