The static mixing system of a kind of High Precision Automatic weight-loss type
Technical field
The utility model relates to a kind of plastics machinery and concentrates feeding system, and especially a kind of plastics machinery is concentrated the static mixing system of the High Precision Automatic weight-loss type of feeding system special use.
Background technology
In industrial production, particularly in the plastics-production industry, need to measure accurately and control the material of Powdered or liquid state etc., dosing is being brought into play more and more important effect aborning, just because of the popularity of its application, if can improve the precision of feeding system, the stability of metering, important realistic meaning is just arranged.At present, for the plastics machinery material loading, concentrate the static mixing system of High Precision Automatic weight-loss type of feeding system, also belong at home blank, general adopt according to different material shapes more, adopt vacuum feeding, the powder material loading, spiral material loading and artificial loading, its blanking device is comprised of variable speed electric motors, particularly and the reinforced engagement type twin-screw of volumetric metering, the cutting stock weight of this device depends on accumulation degree and the screw speed of material, can cause cutting stock weight unstable, the quantity that can not maintain a long-term stability, it only has preliminary mass transport ability, but the recipe ratio according to material is carried out the accurate measurement material loading and is mixed, can't reach its requirement.
" weight loss type feeder for modified engineering plastics for example, application number: 201020l80400.2 ", it discloses a kind of weight loss type feeder for modified engineering plastics, it comprises feed hopper, it is characterized in that: it also comprises weightless storehouse, (discharging opening is connected with weightless storehouse charging aperture by being flexible coupling described feed hopper, on described weightless storehouse, be provided with LOAD CELLS, bottom, described weightless storehouse is provided with agitator, bottom, described weightless storehouse is provided with screw(-type) feeder, described screw(-type) feeder is connected with motor, described screw(-type) feeder discharging opening is connected with conveyance conduit by being flexible coupling.This device structure design is unreasonable, and volume is larger, and particularly it adopts the mode of suspention to be connected on LOAD CELLS in weightless storehouse, makes sensor be subject to the vibration effect of plant equipment, has reduced control accuracy.
Summary of the invention
For solving the problem existed in background technology, the purpose of this utility model is to provide a kind of high accuracy, low maintenance, fully integrated, metering accurately, be mixed evenly, reduce the static mixing system of automatic weight-loss type of material waste, this system can be carried out PLC control, can pass through the blending process implementing monitoring, formula error rate control accuracy is high, and measure control is accurate, and can carry out information storage and remote monitoring.
For achieving the above object, the utility model by the following technical solutions: the static mixing system of a kind of High Precision Automatic weight-loss type comprises hopper, weight-loss type weighing unit, auger conveyor, static blender; Described hopper by bearing support on the weight-loss type weighing unit, and with auger conveyor UNICOM; On described weight-loss type weighing unit, variable-frequency motor is set, variable-frequency motor is supported by supporting base, and the variable-frequency motor output shaft is connected with the helical axis of auger conveyor, and helical axis is placed in the barrel of auger conveyor; The barrel port of export of described auger conveyor is provided with static blender, and static blender is by blanking tube, upper conical blanking body, and inferior pyramidal blanking body forms; Controller is connected with hopper, weight-loss type weighing unit, auger conveyor, static blender respectively.
During work, auger conveyor is pressed fixedly discharging of desired speed, when the weight of material of hopper reaches predetermined value, under the control material is quick, in hopper, when charging reaches predetermined value, stops charging, thereby improves the degree of accuracy and the control accuracy of weighing.
The beneficial effect of the static mixing system of High Precision Automatic weight-loss type of the present utility model is as follows:
1. the utlity model has high accuracy, low maintenance, fully integrated, measure accurately, mix, reduce the material waste, can carry out PLC control, can pass through the blending process implementing monitoring, formula error rate control accuracy is high, measure control is accurate, and can carry out information storage and remote monitoring.
2. the utility model can carry out continuous accurate measurement and abundant mixed material according to the proportioning of material, to reach high accuracy, high-quality purpose, have high accuracy, the low maintenance, fully integrated, guarantee product quality and measuring accuracy, mix, reduce the material waste, improve the uniformity of mixture, the formula error rate is controlled in 0.1%.
3. the utility model has solved the coarse problem of mixed section, carries weight to be easy to control, and has guaranteed that the proportioning of material is errorless, and output and accuracy are higher than traditional mixing system, and the product quality high conformity, be easy to control.
