Abstract

The utility model provides a swing mixing machine which is used for mixing powder lots and provided with a swing mechanism. The swing mixing machine is characterized in that an electric motor simultaneously drives two rollers to move together through a speed reduction device, a driving shaft, and a Y-shaped rocker arm. As the projections of hinge pin shaft lines on both ends of the driving shaft on a plane which is perpendicular to the driving shaft line are mutually perpendicular, when one roller needs greater torque, the other roller needs minor torque. Accordingly, compared with an existing swing mixing machine, the motor power only needs increasing by fifty percent to seventy percent under the condition that the production is increased by twice, and the machine vibration is reduced.

Description

Swing mixer

The utility model relates to a kind of mixing of materials that is used for, particularly the mixing arrangement with swing mechanism of powder mixing.

The shaker mixer that is applied to industries such as dyestuff, food, medicine, chemical industry at present is by motor, deceleration device, and driving shaft, the fork-shaped rocking arm, driven shaft, cylinder and bearing housing thereof are formed.Swiss Patent CH216,760 inventions that provided are exactly this mixer.This mixer mainly is the mixing that is used for powder, also can be used for the mixing of liquid.Motor drives driving shaft by deceleration device and rotates, and driving shaft drives cylinder by the fork-shaped rocking arm and rotates, and cylinder drives driven shaft by another fork-shaped rocking arm and rotates.Between driving shaft and the fork-shaped rocking arm, between fork-shaped rocking arm and the cylinder, link by hinge between fork-shaped rocking arm and the driven shaft.The work intermediate roll has rotation simultaneously, translation and three kinds of motions of swing.The motion mode of this uniqueness of cylinder give with cylinder in a kind of impulse action that replaces of material, make material alternately be in cohesion or dispersity, thereby have outstanding mixed effect.Even two or more materials that contrast heavily differs greatly or quantity differs greatly also can give good mixing.Because cylinder is not general uniform rotation, change by the moment of torsion that the fork-shaped rocking arm passes to cylinder by driving shaft, theory analysis and experiment show, whenever driving shaft rotates a week, with the peak value that two moments of torsion occur is that the valley of peak and two moments of torsion is a minimum, peak value is approximately 2 to 4 with the ratio of valley, and the phasic difference of peak value and valley is 90 degree.If press the required peak torque configuration motor of machine, the machinery load too low made the power factor of motor very low when motor can be in valley at the moment of torsion of driving shaft.

The purpose of this utility model provides a kind of new shaker mixer, makes that the mechanical load of the moment of torsion that driving shaft transmitted of shaker mixer and motor is more steady, under the identical situation of power of motor, improves the output of machine.

The utility model is achieved in that it has motor, deceleration device, driving shaft, driven shaft, cylinder, the fork-shaped rocking arm, bearing housing, between driving shaft and fork-shaped rocking arm, between fork-shaped rocking arm and the cylinder, link by hinge between fork-shaped rocking arm and the driven shaft, it is orthogonal with the two hinge pin axis that are connected the cylinder end that the fork-shaped rocking arm connects the active axle head, the bearing pin axis of two hinges on the cylinder is vertical mutually, it is vertical mutually with the two hinge pin axis that are connected the cylinder end that the fork-shaped rocking arm connects driven axle head, the axis of driving shaft and driven shaft is parallel to each other, motor drives the rotation of driving shaft constant speed by deceleration device, it is characterized in that: the hinge pin axis at the two ends of driving shaft is orthogonal perpendicular to the projection in the plane of driving shaft axis, and driving shaft drives two cylinders rotations simultaneously by the fork-shaped rocking arm at its two ends.

The utility model architectural feature also is: two fork-shaped rocking arms that drive same cylinder have identical physical dimension, or four fork-shaped rocking arms in the device have identical physical dimension.

The utility model architectural feature also is: the physical dimension of two driven shafts in the device is identical.

Above-mentioned shaker mixer is on-stream, because the hinge pin aperture center line of both ends of main drive shaft is in the phasic difference that 90 degree are arranged perpendicular to the projection in the plane of driving shaft axis, again since cylinder at the volley, the peak value of its needed moment of torsion and the phasic difference of valley are 90 degree, this has just guaranteed that it is smaller value that the cylinder of an other end that has the initiative only needs the moment of torsion of driving shaft output when the cylinder of driving shaft one end needs the moment of torsion of driving shaft output to be higher value.Increased a cylinder though therefore compare with original shaker mixer, under the situation that output doubles, power of motor only need increase by 50 to 70 percent.Therefore the mechanical load of motor also becomes steady.Torque by the driving shaft transmission also becomes more steady, and this has reduced mechanical vibration again.Because cylinder places the both sides of bearing housing respectively, a shared bearing housing can reduce floor space thus.

Concrete structure of the present utility model is provided by following examples and accompanying drawing.
