Description

The positive and negative swing gyratory shaker of two guide rods

Technical field

The utility model relates to and is used for fixing the mixer that object mixes in the container, the positive and negative swing gyratory shaker of two guide rods of the positive and negative swing rotation of particularly a kind of shaft.

Background technology

At present, most of general mixer can only stir towards a direction rotation, and the mixed object in the container is also only rotated towards a direction.This makes that fibrous solute dissolving is slow, easily twines for containing fiber in the viscosity ratio higher liquid, particularly liquid or easily during drawing fiber shape solute, forming bad mixed zone easily, and mixing power seriously increases, stirring efficiency reduces greatly.For example: certain manufacturing rubber oar liquid, adopt traditional unidirectional alr mode, stir a cylinder oar liquid time spent and reach 12 hours.Report is arranged and experiment showed, that this type objects adopts positive and negative rotation stirring efficiency to be much higher than the stirring efficiency of folk prescription to rotation.Be both above-mentioned certain manufacturing rubber oar liquid, adopt the alr mode of positive and negative rotary oscillation, stirring a cylinder oar liquid only needs in two and one-half-hours.

The positive and negative rotation stirring technique of having announced at present ZL91229052.8 " positive and negative rotation hold concurrently reciprocating agitator ", ZL00268919.7 " alternation transmission mixer " and ZL01220629.6 " mixer of positive and negative rotation " etc. are arranged.The complex structure that ZL91229052.8 adopts, take up room greatly, the reciprocating motion necessity of rotating shaft is little, and the difficulty of increasing for sealing is very big; ZL00268919.7 adopts intermittently changement of gear, considered that also the commutation motion is easy to generate inertia impact, but because the movement velocity of power shaft is constant, so though inertia impact is littler than not adding the commutation rapidly that just pauses, but can't avoid the inertia impact that very high startup acceleration causes and the mesh impact of the frequent reverse wheel between cog of gear, account for 1/2nd and 1/3rd in addition dead time of (is example to rotate 120 ° and 180 ° of angles), also can reduce real work efficient; The mechanism that ZL01220629.6 adopts is more ingenious, but certain restriction is but arranged for mounting means, decelerator and motor can only be contained in the side and can not be contained on the axial line of shaft, so the real space occupancy is preferred plan not necessarily, simultaneously connecting rod is connected pin (in the specification unlisted and be illustrated) the stressed complexity, stressed big of usefulness in the structure with connecting rod base, is easy to damage.

The utility model content

The purpose of this utility model provide a kind of simple in structure, pendulum angle is easily transferred, it is little to impact, easy for installation, the positive and negative gyratory shaker of two guide rods that stirring efficiency is high.

Realization principle of the present utility model is: at the middle part of general mixer, a movement transforming device is set, converts rotatablely moving of motor or the output of motor acceleration and deceleration device the motion of positive and negative swing rotation to.

The technical scheme that realizes the utility model purpose is: a kind of pair of positive and negative swing gyratory shaker of guide rod comprises motor, reducing gear, movement transforming device, shaft and blade.This movement transforming device is made up of two groups of guide-bar mechanisms.First group is crank guide rod mechanism, comprise crank, bearing, top guide bar and casing, crank is installed on the output shaft of motor, bearing is connected on the crank by pin and is placed in the groove of top guide bar, top guide bar is connected with casing by the guide rod pin, rotatablely moving of crank axle is converted to the swing of top guide bar; Second group is oscillating guidebar mechanism, is made up of top guide bar, driving lever pin, lower guide rod and casing, and the driving lever pin is installed on the top guide bar and with lower guide rod and is connected, and in the pendulum guide rod group, with the swing of top guide bar, is converted to the swing of lower guide rod.Lower guide rod and shaft are rigidly connected, and drive shaft do swing rotation; The power shaft that rotatablely moves of swing is that the shaft that promptly is connected with lower guide rod of output shaft that the output shaft of motor and swinging rotatablely moves is on same axial line.

Compared with prior art, the utility model has brought following beneficial effect: the utility model adopts the method for the length ratio of adjusting fork and guide rod, makes to drive the final needed pendulum angle of guide rod that obtains shaft and realize agitating function.Consider the problem of structure and efficient, the angle of two groups of mechanism's guide rod pendulum angles can be carried out suitable calculating adjustment as required, in the utility model, as long as adjust the offset of crank.The pendulum angle that first, second group guide rod of the utility model is selected for use is respectively: 60 ° and 120 °.Simultaneously, the angular acceleration of the crank guide rod mechanism of employing of the present utility model when the swing commutation is zero, so the inertia impact when commutating in other mechanisms has steadily been eliminated in the utility model motion.The power shaft that swing of the present utility model rotatablely moves be the shaft that is connected with lower guide rod of output shaft and the output shaft that rotatablely moves of swing of motor on same axial line, bring bigger convenience to installation, also make complete machine that better outward appearance is arranged.
