Be equipped with (mixing) shaft 23 in the agitator 2, the vertical setting of (mixing) shaft 23 in this embodiment, and (mixing) shaft 23 is coaxial with agitator 2, and (mixing) shaft 23 upper end and support threaded connection. Be equipped with push pedal 22 in agitator 2, it is concrete, push pedal 22 bottom offsets with the bottom of agitator 2, and push pedal 22 in this embodiment is the cross along horizontal cross-section, and the welding of push pedal 22 top is in the bottom of (mixing) shaft 23, and the length of push pedal 22 is greater than the internal diameter of measuring bucket 3.
The specific implementation process is as follows:
the present embodiment describes the operation of the device by taking the example of configuring a mixed medicament including a medicament 1, a medicament 2, and a medicament 3 in a volume of 1:2: 3. Initially, the top of the piston 31 is equal to the top of the measuring barrel 3 in height, and when the medicines need to be proportionally configured, the pushing member 4 is manually started, the push rod of the pushing member 4 is controlled to retract, so that the measuring rod 32 slides downwards, when the pushing member slides to the position corresponding to the scale mark of '1' and the bottom of the measuring barrel 3, the pushing member 4 is closed, the first driving member is opened, the first driving member drives the stirring barrel 2 and the measuring barrel 3 to rotate forwards, and at the moment, the measuring barrel 3 rotates forwards relative to the push plate 22 and the stirring shaft 23.
Then, the medicine 1 is squeezed into the measuring barrel 3 from the upper end of the measuring barrel 3, the medicine entering the measuring barrel 3 falls on the piston 31 and rotates along with the measuring barrel 3, when the medicine 1 on the piston 31 increases, the medicine 1 which just enters is protruded upwards, and after the medicine 1 is contacted with the bottom of the push plate 22, the medicine 1 is pushed flat by the bottom of the push plate 22, and when the medicine 1 is completely filled in the measuring chamber, the medicine 1 is stopped being squeezed in.
Then the first driving piece is closed, the pushing piece 4 is opened, the push rod of the pushing piece 4 is controlled to retract, the piston 31 is made to slide downwards, when the scale mark of 3 is aligned with the bottom of the measuring barrel 3, the first driving piece is opened after the pushing piece 4 is closed, the first driving piece is controlled to drive the stirring barrel 2 to rotate in the reverse direction, then the medicine 2 is squeezed into the measuring barrel 3 from the upper side of the measuring barrel 3, when the measuring chamber is completely filled with the medicine 2, the squeezing of the medicine 2 is stopped, the steps are repeated, the measuring rod 32 is made to slide downwards to the scale mark of 6 to slide to the position opposite to the bottom of the measuring barrel 3, and the medicine 3 is squeezed into the measuring barrel 3 again. When the dose 3 has completely filled the measurement chamber, the measurement of the entire dose is completed.
Then slide piston 31 upwards through impeller 4, push 3 kinds of medicaments in the measuring chamber one by one in agitator 2, when the medicament passes through push pedal 22, under the effect of push pedal 22, the medicament is by even dispersion to slide to being close to agitator 2 inner wall one side under centrifugal action, close impeller 4 when piston 31 slides to pasting with push pedal 22 bottom at last, push pedal 22 and (mixing) shaft 23 stir the medicament in agitator 2.
In the stirring process, through impeller 4 control piston 31 up-and-down reciprocating sliding, when piston 31 glides downwards, inhale the medicament in agitator 2 in measuring bucket 3, when piston 31 glides upwards, impel inspiratory medicament to glide upwards, get into agitator 2 once more, so, can impel the medicament along vertical slip, improve the stirring effect.
Example 2
In addition to embodiment 1, as shown in fig. 2, an annular retainer 6 is provided in the mixer drum 2 in this embodiment, and the outer wall of the retainer 6 is attached to the inner wall of the mixer drum 2. The left side and the right side of the retainer ring 6 are respectively provided with a lower pressing rod 51 and a guide rod, and the lower ends of the lower pressing rod 51 and the guide rod are welded on the retainer ring 6. The upper end of the guide rod penetrates through the bracket, and a pressing component is arranged above the pressing rod 51.
The pressing assembly comprises a spring, a cam 5 and a second driving piece, the second driving piece in the embodiment adopts a motor, and the second driving piece is fixed on the bracket through a bolt. The output shaft of the second driving member is connected to a cam 5 through a spline, and the cam 5 is opposed to the top of the push-down lever 51. The upper end of the lower pressure lever 51 is welded with a convex block, and the two ends of the spring are respectively welded on the convex block and the bracket.
When measuring the medicament, the check ring 6 is positioned at the upper end of the stirring barrel 2 under the action of the spring. When the medicament is stirred, after the medicament completely enters the stirring barrel 2, the second driving piece is started, the second driving piece drives the cam 5 to rotate, the lower pressing rod 51 is pushed downwards in the rotating process of the cam 5, the retainer ring 6 is enabled to slide downwards, the medicament adhered to the inner wall of the stirring barrel 2 is pushed downwards, and meanwhile, the piston 31 slides downwards through the pushing piece 4, and the medicament in the stirring barrel 2 is sucked into the measuring barrel 3.
After the cam 5 releases the lower pressing rod 51, the lower pressing rod 51 resets under the action of the spring, the retainer ring 6 slides upwards along with the lower pressing rod, the control piston 31 slides upwards at the moment, the medicament is pushed into the stirring barrel 2 again to be stirred, the medicament is further promoted to move vertically, and the stirring effect is improved.
When the mixed medicament is to be used, the first drive member, the second drive member and the pusher 4 are all in the closed position, and the piston 31 is located at the upper end of the measuring cylinder 3. Along with the use of mixing the medicament, just reduce the back to the medicament of retaining ring 6 middle part cavity position, because part medicament is located retaining ring 6 below, it is comparatively inconvenient to use, make retaining ring 6 lapse through the second driving piece this moment, when promoting the adhesion in the medicament of 2 inner walls of agitator downwards, because the space between retaining ring 6 bottom and the 2 bottoms of agitator reduces, the medicament that is located retaining ring 6 below is to being close to (mixing) shaft 23 one side motion under the squeezing action of retaining ring 6, the medicament is just to the cavity position at retaining ring 6 middle part this moment, facilitate the use, after retaining ring 6 slides to the bottom of agitator 2, close the second driving piece.
The foregoing is merely an example of the present invention and common general knowledge in the art of designing and/or characterizing particular aspects and/or features is not described in any greater detail herein. It should be noted that, for those skilled in the art, without departing from the technical solution of the present invention, several variations and modifications can be made, which should also be regarded as the protection scope of the present invention, and these will not affect the effect of the implementation of the present invention and the practicability of the patent. The scope of the claims of the present application shall be determined by the contents of the claims, and the description of the embodiments and the like in the specification shall be used to explain the contents of the claims.
