Embodiment Construction

[0013] The present invention is described below in conjunction with accompanying drawing.

[0014] as attached figure 1 , 2 The shown down filling tube of the present invention includes a tube body 1, a baffle 2 and a torsion spring (not shown in the figure); the tail end of the tube body 1 is provided with a baffle 2; the baffle The piece 2 is hinged with the tube body 1; the hinge of the tube body 1 and the blocking piece 2 is provided with a torsion spring; the tube body 1 is also provided with an inner sleeve 3.

[0015] In the down-filling tube of the present invention, during the down-feeding process, the airflow conveying down overcomes the torsion of the torsion spring, pushes away the flap, and conveys the down; when the down-feeding is completed, the flap is closed due to the torsion of the torsion spring. The down filling tube of the present invention can only transport down in one direction, and can well prevent the down from flowing backward.

Abstract

The invention discloses a down feather feeding pipe. The down feather feeding pipe comprises a pipe body, a baffle and a torsion spring, wherein the baffle is arranged at the tail end of the pipe body and hinged to the pipe body, the torsion spring is arranged in the hinging position of the pipe body and the baffle, and an inner sleeved pipe is further arranged inside the pipe body. In the down feather conveying process of the down feather feeding pipe, the air flow for conveying down feather overcomes the torsion of the torsion spring, jacks the baffle open and conveys the down feather. After the down feather is conveyed, the baffle is closed due to the torsion of the torsion spring. The down feather feeding pipe can only convey the down feather in a signal direction, and can well prevent the down feather from flowing backwards.

Description

technical field [0001] The invention relates to a down filling tube, in particular to a down filling tube of a small down filling machine, and belongs to the technical field of components of down filling devices. Background technique [0002] my country is a big down producing country. 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 gall cavity to be filled, and grasp the mouth of the down by hand, then To prevent the down from overflowing during down filling, the blower is used to generate an inhaled airflow to fill the down into the cavity through the high-speed rotating impeller; for down products with small cavity, the filling amount at one time is very small, and the operator will weigh it in advance. The down is stuffed into the gall cavity by hand. Filling with a blower has high efficiency, but the high-speed rotating impeller will damage the down and consume a lot o...
