Automatic down filling machine filling down precisely

Abstract

The invention discloses an automatic down filling machine filling down precisely. The automatic down filling machine comprises a down storage box, weighing cabinets, weighing boxes, down filling pipes, a control mechanism and conveying mechanisms, wherein the weighing cabinets are arranged on the two sides of the down storage box; the weighing boxes are arranged in the weighing cabinets; the down filling pipes are arranged on the weighing cabinets and connected with the conveying mechanisms; the conveying mechanisms are controlled by the control mechanism; each weighing box comprises a closed weighing box body, a bottom plate, a weighing sensor and an air outlet connecting pipe; each weighing sensor is fixed below each bottom plate; each weighing box body is fixed on the bottom plate; each weighing box body is perpendicular to each bottom plate; an air inlet pipe orifice is formed at the upper part of each weighing box body; each air outlet connecting pipe is arranged at the lower part of each weighing box body; each air inlet pipe orifice and each air outlet connecting pipe are connected with each conveying mechanism; ventilated windows are formed at the peripheries of cuboids at the upper parts of the box bodies; and filter screens are arranged on the ventilated windows. The automatic down filling machine filling the down precisely is high in down filling precision and good in down filling effect.

Description

technical field [0001] The invention relates to a down filling device, in particular to an automatic down filling machine, which belongs to the technical field of down filling devices. Background technique [0002] At present, there are two main methods of filling down in down products: for a large amount of filling at one time, first insert the down pipe into the cavity to be filled, and grasp the mouth of the down to prevent the down from overflowing during filling , and then use the blower to generate inhalation airflow to fill the down into the cavity through the high-speed rotating impeller; for down products with a small cavity, the filling amount is very small at one time, and the operator will stuff the down weighed in advance into the cavity by hand. In the gall cavity. Filling with a blower has high efficiency, but the high-speed rotating impeller will damage the down and consume a lot of energy; the manual filling method has defects such as low efficiency, poor w...

But in the process of actual use, the transmission mechanism transports the down in the down storage box to the weighing box, and the airflow conveying the down enters the weighing box and then flows out through the ventilation window. Since there is a ventilation window on the upper part of the weighing box, The air flow can only flow out from this ventilation window, causing the weighing box to shake slightly, thus affecting the weighing accuracy of the weighing box, and thus affecting the down filling accuracy of the down filling machine
