a velvet tube

Abstract

The invention discloses a down filling pipe which comprises a down filling pipe body, wherein a lock clamp device is arranged at the front end of the down filling pipe body. According to the down filling pipe, since the lock clamp device is arranged at the front end of the down filling pipe body, an operator is only required to insert the front end of the down filling pipe body into a liner chamber to be filled with down products and then controls the lock clamp device during down filling, the lock clamp device can clamp cloth with the front end of the down filling pipe body tightly, the labor intensity of the operator is reduced, the down leakage is avoided, the working environment is improved, and the waste of expensive down is avoided.

Description

technical field [0001] The invention relates to a down filling device, in particular to a down filling tube, 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-filling tube 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 workin...

AI Technical Summary

Problems solved by technology

However, when the down-filling tube is in use, the operator needs to insert the down-filling tube into the cavity of the down product to be filled, and then grasp the cloth and the down-filling tube by hand. Fatigue occurs. Once the fabric and the down-filling tube are not tightly grasped, that is, a little loose, the down will overflow, which affects the working environment and causes waste of expensive down
