There is the required accompanying drawing used in technology description to be briefly described, it should be apparent that, drawings in the following description are only this
The embodiment of invention, for those of ordinary skill in the art, on the premise of not paying creative work, can also basis
The accompanying drawing of offer obtains other accompanying drawings.
Fig. 1 is a kind of structure chart of the powder micro-measurement screw rod based on servo-drive of the embodiment of the present invention；
Fig. 2 is a kind of blade of powder micro-measurement screw rod and the vertical view of screw rod based on servo-drive of the embodiment of the present invention
Figure.
Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation describes, it is clear that described embodiment is only part of the embodiment of the present invention, rather than whole embodiments.It is based on
Embodiment in the present invention, those of ordinary skill in the art are obtained every other under the premise of creative work is not made
Embodiment, belong to the scope of protection of the invention.
Refer to Fig. 1 to Fig. 2, a kind of technical side of the powder micro-measurement screw rod based on servo-drive of the embodiment of the present invention
Case includes：
Driving part 1, gear-box 2, mixing component 3, transfer unit 4 and discharging mouthpiece 5.
Driving part 1 includes servomotor and the reductor being connected with servomotor, servomotor, reductor and output shaft
It is sequentially connected, the output shaft that servomotor is used for sliding tooth roller box 2 rotates.
Gear-box 2 includes casing and the input shaft being arranged in casing；At least two output shafts, gear are additionally provided with casing
The output shaft of case may be designed as rotating Vortex or counter rotating two ways, powder microflowmeter of the present embodiment based on servo-drive
Amount screw rod limits output shaft as rotating Vortex.
Mixing component 3 includes agitating shaft and the blade being arranged on agitating shaft, and blade quantity is at least one, works as the number of blade
Measure for two or more when, blade is circumferentially disposed along agitating shaft.As shown in Fig. 2 blade 31 is located at the top of screw rod 41, and both it
Between there is gap.Specifically, agitating shaft is Longitudinal extending, some blades 31 can circumferentially be uniformly arranged on stirring along the vertical direction
The bottom of axle, stirring motor driving agitating shaft rotate and rotate stirring raw material with movable vane piece 31, and compact-sized, torque is big, transmission
Efficiency high, it is easy to operate, and blade 31 can be the curved structure of spiral torsional, this blade 31 have larger DIFFUSION IN TURBULENCE power and compared with
Low shearing force, reduce resistance when blade 31 rotates stirring raw material so that agitating device smooth running, noise is low, and stirring is former
Material is uniform.
Transfer unit 4 includes barrel and is built in the screw rod 41 of barrel, and the quantity of screw rod 41 is consistent with output shaft, and with it is defeated
Shaft connects one to one.It should be noted that multiple screw rods in the present embodiment can be intermeshed.
It is conveying capacity according to screw rod transmission gauge amount formula V=F × H × n × ε × η, wherein V, F is free volume, and H is
Screw rod helical pitch, n are screw speed, and ε is charging efficiency, and η is transfer efficiency.
As can be seen that on the premise of ε and η is stable from formula, when conveying micro powder, F, H and n need to be reduced,
Wherein F and H is the form parameter of conveying screw rod, and difficult and processing cost lifting can be brought to processing by being made too small；And rotating speed n
Then determined by motor and mediation member, but common electric machine under the low speed easily drift about by speed, and rotary speed unstabilization is fixed, so as to make
Fluctuated into feed flow, therefore by setting servomotor to solve above-mentioned technical problem in the present embodiment.
After F, H and n are stable, ε and η then turn into the main reason for influence conveys stability.Wherein η transfer efficiencies mainly by
The material and the structure of screw rod conveyed together decides on, and in the case of single screw rod conveying or non-engaging spiro rod, material easily exists
Adhesion accumulation occurs for screw rod groove portion, reach it is a certain amount of after adhesion layer peel off, low when high during so as to cause transfer efficiency, influence
Measuring accuracy.Therefore it is intermeshed using screw rod in the present embodiment, when screw rod rotate with entirely from cleaning function, from basic
On solve the problems, such as flowed fluctuation in course of conveying.In terms of still further aspect, before conveying stabilization is built upon feed stabilization
Put, the stabilization of charging aperture pan feeding speed is presented as in this equipment, is understood from principle, be the stabilization of ε charging efficiencies
Property.Approximately, the origin cause of formation of pan feeding flowed fluctuation is similar with the genetic facies of flowed fluctuation in course of conveying.Set in past same type
In standby, to solve the problems, such as that charging aperture bridge formation increases lateral agitating paddle, but there is stirring blind area, feeding mouth surrounding position in lateral agitating paddle
Put and still suffer from bridge formation risk.A kind of spiral plane agitating paddle is employed in the present embodiment, between blade bottom and conveying screw rod between
Gap is minimum while can carry out sweeping to whole feeding mouth section, in the absence of stirring blind area, so as to solve asking for charging aperture bridge formation
Topic.
The present invention is described in detail above, for those of ordinary skill in the art, according to the embodiment of the present invention
Thought, there will be changes in specific embodiments and applications, in summary, this specification content should not be understood
For limitation of the present invention.
