Down filling head

Abstract

The invention discloses a down filling head which comprises a down outputting pipe, an air return pipe and an outer sleeve. The outer sleeve comprises a sleeve cavity and a down filling nozzle connected with one end of the sleeve cavity, the other end of the sleeve cavity is sealed by a flange, the air return pipe is sleeved outside the down outputting pipe, the other end of the air return pipe is sealed with the other end of the down outputting pipe, one ends of the down outputting pipe and the air return pipe are arranged in the sleeve cavity while the other ends of the same extend out of the sleeve cavity, an air return hole is formed in an air return pipe body positioned outside of the sleeve cavity, an outer air return pipe is sleeved outside the down filling nozzle, and an outer air return space is formed between the down filling nozzle and the outer air return pipe; at a down outlet of the down filling nozzle, an interval between one end of the outer air return pipe and the down filling nozzle is smaller than that allowing down to pass, and an air outlet is arranged between the other end of the outer air return pipe and the down filling nozzle. When the down filling head is utilized for down filling, the down cannot fly around, so that environment is unaffected, and weight of the down entering a garment piece is guaranteed; and more importantly, smoothness of air return is guaranteed, so that plumping of the garment piece is avoided.

Description

technical field [0001] The invention relates to a down filling head for an automatic down filling machine. Background technique [0002] The utility model patent with the authorized announcement number CN202247079U discloses a down filling tube (i.e. down filling head) used on a fully automatic down filling machine. The down filling tube and the utility model patent with the authorized announcement No. 202808338U disclose a filling The structure of the down tube is similar. This type of down tube includes an inner tube and a sleeve. There is a gas return channel between the inner tube and the sleeve. The end of the sleeve is sealed with the inner tube. The back end of the sleeve is equipped with a collection branch pipe, which is connected to the return flow channel. During the whole process of filling down, the down enters the predetermined position with the airflow, and the gas flows out from the sleeve, so that it can be efficiently to fill with cashmere.

AI Technical Summary

Problems solved by technology

[0004] 1. Down can enter the return channel, and then flow out of the working environment along other return holes, which will cause environmental problems and waste down;

[0005] 2. The outflowing down is a part of the down that has been measured accurately, and the weight of the down filled in the clothing will not meet the standard after the outflow;

[0006] 3. Some down will be blocked in the air return hole, causing the air return to be blocked

However, some garment parts are semi-breathable or even airtight, and the airflow entering them will not be discharged, so that the garment parts will bubble and bulge, which will affect the smooth progress of the down filling work.
