Anti-static down feather weighing box

Abstract

The invention discloses an anti-static down feather weighing box, and belongs to auxiliary facilities of a down filling machine. The anti-static down feather weighing box comprises a base plate, a weighing box body composed of an upper box body and a lower box body, a down feather inlet tube, a down feather outlet tube and an air filter screen arranged on the side wall of the upper box body, wherein the down feather outlet tube is fixed to the base plate and is communicated with the lower box body; a top air filter screen is arranged at the top of the upper box body; a down feather collection and extraction hopper is arranged in a cavity of the lower box body; the down feather inlet tube or the down feather outlet tube is connected with one end of an anti-static lead wire; the other end of the anti-static lead wire is a ground terminal; when one end of the anti-static lead wire is connected with the down feather inlet tube, the down feather inlet tube is made of metallic materials, the down feather outlet tube is made of metallic or nonmetallic materials; when the anti-static lead wire is connected with the down feather outlet tube, the down feather outlet tube is made of metallic materials, and the down feather inlet tube is made of metallic or nonmetallic materials. The anti-static down feather weighing box can prevent the down feather from getting out, and has the advantages that the box body is protected; velvet accumulation is avoided; energy consumption is reduced; the weighing accuracy and security are guaranteed.

Description

Technical field [0001] The present invention is a auxiliary facility technology field for the charging machine, which involves a kind of anti -static down weight box. Background technique [0002] The charging machine mentioned above can be seen in the public Chinese and foreign patent documents.

Problems solved by technology

[0005] It is not limited to the down weighing box exemplified above and has the following disadvantages: First, due to the influence of the traditional design concept, the down outlet pipe is connected to the lower side of the weighing box body, so although it can meet the requirements of the down in the negative pressure state. Under the requirement that the body of the self-weighing box enters the down tube through the down outlet tube, but the negative pressure usually needs to be kept at a level greater than 0.3MPa, that is to say, the down pressure must be above 0.3MPa, so when the down is drawn out of the weighing box When the body enters the down tube, it is easy to drill out from the pinholes on the down tube (the pinholes produced when sewing the down tube). On the one hand, it affects the workplace, that is, the environment of the down filling place. Cause down waste, on the other hand, affect the actual amount of down filling due to the escape of down and damage the reputation of down product manufacturers

Some people may suggest that reducing the negative pressure of the aforementioned down can avoid the phenomenon that the down is drilled from the pinhole of the down tube. However, when the negative pressure is reduced to below 0.3MPa, the experiment shows that the weight in the weighing box It is difficult for the down to enter the down tube through the down outlet tube, and even cause the down filling to fail; secondly, because the down tube is usually relatively narrow after quilting, in order to have a good control effect on the down in the adjacent down tube, avoid Under the state of use, feathers are piled up, so the volume of the weighing box is usually enough to meet the weight of eider down of about 3g, that is to say, the overall volume of the weighing box is relatively small, but because the weighing box in the prior art The box body is only provided with a filter screen around it (such as CN200814517U, which is called a breathable window), so under the action of the air flow, the down in the down box in a fluffy state is introduced into the weighing box box through the down introduction pipe, due to the air mixed in the down It is difficult to lead out from the filter screen to the outside in time, resulting in poor cashmere feeding and even deformation and cracking of the weighing box; third, since the weighing box is usually composed of upper and lower parts, the upper part is a cuboid and the lower part is a An inverted quadrangular truss that is narrowed from top to bottom and connected to a cuboid, and in order to ensure the effective air-permeable area, the side length of the upper part is increased as much as possible, so as to increase the effective area of ​​the filter screen arranged on the surrounding walls of the upper part. However, increasing the side length of the upper part of the weighing box also increases the size of the lower inverted square platform, so the diameter (inner diameter) of the part corresponding to the down outlet pipe also increases accordingly, resulting in weighing Down accumulation occurs at the bottom of the heavy box. The current method is to increase the down pressure to make up for it. However, increasing the down pressure will not only cause the technical problem of drilling down (down drilled from the needle hole of the down bobbin). In addition, it also causes an increase in energy consumption; Fourth, due to the lack of anti-static measures, it is very easy to affect the weighing accuracy and there are unwanted safety hazards caused by static electricity
