Down filling machine filling down precisely

Abstract

The invention discloses a down filling machine filling down precisely. Weighing cabinets are arranged on the two sides of a down storage box; weighing boxes are arranged in the weighing cabinets; down filling pipes are arranged on the weighing cabinets and connected with conveying mechanisms; the conveying mechanisms are controlled by a control mechanism; the control mechanism controls the conveying mechanisms to convey the down in the down storage boxes into the weighing boxes and then discharge the down in the weighing boxes from the down filling pipes; each down filling pipe comprises a down inlet pipe, a connecting pipe and a down outlet pipe which are sequentially connected into a down filling pipe body; an air return pipe and a blowing pipe are arranged on each down inlet pipe; the down inlet pipes, the air return pipes and the blowing pipes are connected with the conveying mechanisms; the air return pipes and the blowing pipes are communicated with the down inlet pipes; each down filling pipe body is internally provided with a down conveying pipe; a gap is reserved between the front end of each down conveying pipe and the tail end of each down outlet pipe; an air return filter screen pipe is fixed between each down conveying pipe and each down filling pipe body; and each air return pipe is communicated with each air return filter screen pipe. The 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 a down filling machine, and 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 working enviro...

Problems solved by technology

However, during actual use, the down will remain in the down filling tube, resulting in inaccurate down filling each time, poor filling effect, and unguaranteed quality of down filling. At the same time, down will be wasted. Clean up, after a long time of use, the down will accumulate more and more, which may cause the down filling tube to be unusable, thus affecting the use of the down filling machine
