Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a powder charging device for a dye liquor blending machine.

[Prior Art] The dye liquid supplied to a dyeing machine such as a continuous pad dyeing machine is prepared using dyes of various colors, dyeing aids, and water as raw materials.

As the dye, sometimes a liquid dye is used, and sometimes a powder dye is used. As for dyeing aids such as surfactants and finishing pastes, liquid urea, starch paste, succinol, sodium alginate, etc., and powdered sodium chloride, soda ash, etc. are used.

The liquids prepared in each dedicated tank, that is, liquid dye, liquid auxiliary agent, and water, are prepared using a dispenser having a cylinder and a piston, which is controlled by a microcomputer, as shown in Japanese Patent Publication No. 12386/1986, for example. A predetermined amount can be automatically fed to the liquid preparation tank.

However, because it has been difficult to automate powder handling for powder dyes and powder auxiliaries, conventional methods have been to use pre-measured powder directly placed in a container after feeding the liquid into the liquid preparation tank. There was no other choice but to insert the body manually.

Problems to be solved by the invention
Since the powder to be charged is placed directly into the container, there is a problem that the powder in the container deteriorates due to moisture absorption, or scatters and mixes with other weighed powders or contaminates the surrounding environment.

In addition, human errors such as adding the wrong powder or forgetting to add the powder may occur, and the desired dye solution may not be obtained. If dyeing is performed without obtaining the desired dye solution, it becomes necessary to dye the fabric, etc., which has been dyed once again, resulting in a decrease in the efficiency of the dyeing process.

SUMMARY OF THE INVENTION An object of the present invention is to provide a powder feeding device for a dye liquor mixer that solves the above problems by automating the feeding of powder necessary for dyeing.
