Description

Technical Field

[0001] The utility model relates to an auxiliary device of a down filling machine, in particular to a weighing box for automatically cleaning down ash (down ash refers to down, dust or similar impurities). Background Art

[0002] A complete set of down filling machines is usually equipped with a down weighing mechanism, which is usually composed of a box and a weighing bin arranged in the box. The weighing bin is fixed in the box through a frame. During the operation of the down filling machine, the filling material is transported from the filling box to the weighing bin of the weighing box. The weighing bin is equipped with a weighing sensor, which can accurately measure the weight of the filling material. The control system of the down filling machine will automatically control the operation of the down filling machine according to the preset filling amount and weight to ensure the accuracy and consistency of the filling material. Finally, the down is filled into the prefabricated cut pieces through the filling head.

[0003] When the down is transferred from the filling box to the weighing box, since the down is relatively light, some of it will fall outside the weighing bin and form down ash after a long period of accumulation. It is usually necessary to open the box manually for cleaning, which is time-consuming and labor-intensive and needs to be improved. Utility Model Content
