Down filling head with improved structure

Abstract

The invention relates to a down filling head with an improved structure, and belongs to the technical field of filling equipment for down products. The down filling head comprises an outer sleeve pipe, an air return pipe and a down filling pipe, wherein one end of the outer sleeve pipe is provided with a down outlet pipe in a contraction way, the cavity of the down outlet pipe is communicated with the cavity of the outer sleeve pipe, the other end of the down outlet pipe is provided with the fixed flange disc of the outer sleeve pipe, one end of the air return pipe is inserted into the cavity of the outer sleeve pipe, the pipe wall of one end of the air return pipe is provided with an air return hole, the other end of the air return pipe extends out of the cavity of the outer sleeve pipe, the down filling pipe is positioned in the cavity of the air return pipe, a down outlet at one end of the down filling pipe extends out of the cavity of the air return pipe, and the down outlet is correspondingly communicated with the cavity of the down outlet pipe. The down filling head is characterized by also comprising an automatic cleaning mechanism of the air return pipe, wherein the automatic cleaning mechanism is arranged at the other end of the air return pipe, the other end of the air return pipe is provided with a pneumatic pipeline valve joint, and the pneumatic pipeline valve joint is provided with a pneumatic pipeline valve. The down filling head has the advantages that the labor strength of workers is obviously reduced, and the working efficiency of a down filling machine is ensured.

Description

technical field [0001] The invention belongs to the technical field of filling equipment for down products, and in particular relates to a down filling head with improved structure. Background technique [0002] The aforementioned down products are not limited to such as down jackets, duvets, down pads, down pillows, etc. When making such products, it is necessary to fill the down into prefabricated tubes, and then quilting to form down products. [0003] Before the introduction of special down filling machines, most down products manufacturers manually filled the tubes with down. This operation method has the following shortcomings: first, the labor intensity of the workers is high and the efficiency is low; second, the filling volume error is large, Affect the quality of down products and even damage the reputation of the business, because in the process of manual down filling, workers use electronic scales or similar measuring instruments to measure, and the judgment of ...

AI Technical Summary

Problems solved by technology

It can be seen that there are at least the following technical problems in this method of cleaning the return air pipe: first, the labor intensity of the workers is high; second, it affects the work efficiency of the down filling machine; Cleaning at a specified time will cause the down filling work to be interrupted suddenly, and if the cleaning is not thorough, it will affect the reasonable period or reasonable time for smooth filling
