Description
Technical field
The utility model belongs to granular material weighing-appliance technical field, especially relates to a kind of granular material accurate weighing system automatically.
Background technology
What current printing and dyeing mill dyeing adopted mostly is that technologist outputs material list according to formula, and then arrive material room scale and go out dyestuff, often kind of dyestuff, by manually being gone out by electronic balance scale, enters production.If there is aberration in production process, then formula adjustment is carried out to the dyestuff inside dye vat.Adopt in this way, often also exist because the inaccurate of artificial weighing causes aberration, even get wrong dyestuff, cause serious economic loss.Because pulvis dyestuff is weighed by the carrying out of manual a spoonful a spoonful, pure manual operations, process is loaded down with trivial details, and outside dyestuff can be scattered in often, causes waste and pollute working environment.
In order to solve the deficiencies in the prior art, there has been proposed various solution, as Chinese patent literature discloses a kind of powder dye automatic weighing system [application number: 201310218100.7], its system comprises frame, charging gear, mobile revolving dials manipulator, mobile splicing dolly and electric cabinet, multiple charging gear is disposed side by side in frame, below the front end of charging gear, correspondence arranges mobile splicing dolly, mobile revolving is set in the rear end correspondence of charging gear and dials manipulator, electric cabinet is arranged on frame side, charging gear comprises dyestuff case and screw feeder, dyestuff lower box part installs screw feeder, screw feeder front end is shaped with discharge opening, screw feeder rear end and mobile revolving are dialled manipulator and are coordinated and realize discharging, dyestuff upper box part is connected with feed pipe and negative tube, this negative tube connects negative-pressure air fan.
Such scheme structure is simple, design science reasonable, effectively improve the weighing efficiency of dyeing recipe, weighs reproducible, avoids pulvis to pollute working environment, and liberation labour power, improves working environment.But scheme at least exists following weak point: be difficult to after when long-term time clean filter, even if dust also can be caused when carrying out clean to expand, serious environment pollution, and weighing precision is not high.On the other hand, weighing precision is difficult to ensure, Long-Time Service can cause precision to reduce, and easily causes granular material to waste.In addition, in granular material weighing process, equally easily dust pollution is caused.
