Description

Gravity type autoweighting mixer

Technical field

The present invention relates to the quantitative mixing dye technology field of plastic grain, refer more particularly to and plastic grain quantitatively can be mixed painted gravity type autoweighting mixer.

Background technology

Produce on the market now be used for plastic grain quantitative the autoweighting mixer of the mixture of colours, mostly be the formula of whisking, what whisk the employing of formula autoweighting mixer is the horizontal metering and conveying device, described metering and conveying device comprises cylindrical shell, the inside of cylindrical shell is equipped with feeding spiro rod, one end of described cylindrical shell is provided with the reductor of drive screw, the other end of cylindrical shell is a discharging opening, the top of cylindrical shell is provided with charging aperture, described charging aperture is connected with feed hopper, when the metering and conveying device metering finishes to stop to carry, because metering and conveying device is a horizontal, easily produces landing so be positioned at the plastic grain of metering and conveying device discharging opening, thereby causes the metering inaccuracy, now the measuring accuracy of the autoweighting mixer of producing on the market be generally ± 1%, can only be used for the lower place of mixed-precision requirement; What whisk that the mixing coloured part of formula autoweighting mixer adopts is shaft, and when shaft stirred, the sinking that plastic grain is heavy, light come-up were easy to generate non-uniform phenomenon, thereby cause aberration.

Summary of the invention

Technical problem to be solved by this invention is: a kind of gravity type autoweighting mixer that can make plastic grain measuring accuracy height, uniform coloring when quantitatively mixing is painted is provided.

For addressing the above problem, the technical solution used in the present invention is: gravity type autoweighting mixer, comprise at least two feed hoppers, the bottom of each feed hopper connects the charging aperture of corresponding metering and conveying device, the discharging opening of each metering and conveying device all is connected to and is mixed into hopper, the described below that is mixed into hopper is provided with and is attached thereto logical mixing casing, described metering and conveying device is the tilting setting, the charging aperture of metering and conveying device all is lower than its discharging opening, the inside of described mixing casing is provided with from top to bottom: upper hopper, awl cap and following funnel, upper hopper, there are the gap each other in awl cap and following funnel, the upper edge of upper hopper and following funnel all fits with the inwall that mixes casing, the top of described awl cap be positioned at upper hopper discharging opening under, the gap formation Flow of Goods and Materials passage between lower edge and the inwall that mixes casing of awl cap.

The angle of inclination that described metering and conveying device is become with horizontal direction is 10~20 degree.

Described metering and conveying device comprises cylindrical shell, the inside of cylindrical shell is equipped with feeding spiro rod, and an end of described cylindrical shell is provided with the reductor of drive screw, and the other end of cylindrical shell is a discharging opening, the top of cylindrical shell is provided with charging aperture, and described charging aperture is connected with feed hopper.

The invention has the beneficial effects as follows: the present invention adopts the metering and conveying device of tilting, and the charging aperture of metering and conveying device is lower than its discharging opening, eliminated the landing phenomenon of material after metering finishes, thereby measuring accuracy is increased to ± 0.5%; What mixing coloured part of the present invention adopted is the hybrid technology of simple waterfall type, by upper hopper, awl cap and following funnel being set from top to bottom at the mixing box house, material is subjected to the gravity effect, from top to bottom successively through upper hopper, awl cap and following funnel, material carries out " close-minute-close " three and intersects mutually and see through mixed process in whole flow process, reach the purpose of mixing uniform coloring, thereby eliminated the painted uneven phenomenon of the caused mixing of mechanical agitation.
