Abstract

An electronic speed-regulating flexible shaft driven stirrer belongs to chemical experiment stirring equipment, is an improvement of a traditional stirring rod directly driven by a motor, mainly comprises a speed regulator, a flexible shaft, a coupler and a stirring rod, integrates a driving element with the electronic speed regulator, and is driven by the flexible shaft and vertically finely adjusted by the coupler, so that the stirrer has the advantages of convenience and dexterity in regulation, light weight and high working efficiency.

Description

Electronic speed-regulating mixer driven by a flexible shaft

The utility model relates to a kind of electronic speed regulation flexible axle and drives agitator, belongs to the chemical engineering experiment mixing plant.

The kind of drive of known common experimental agitator is directly to drive stirring rod by motor to carry out transmission and stir, and when needs are often regulated the motor upright position, regulates trouble because of motor is heavy, and experimental work is time-consuming takes a lot of work, efficient is low.

The purpose of this utility model is to avoid the above-mentioned weak point of prior art, and a kind of upright position is fine-tuning, easy to adjust, the electronic speed regulation flexible axle of electromechanical drives agitator and provide.

The purpose of this utility model reaches by following technical measures.

The utility model includes a platform that has a column, fixedly respectively there is the flexible axle of a nut at slide block and two connecting rods, a stirring rod and the two ends that column is connected respectively through two, the panel of one velometer is provided with conversion stacked switch, indicator lamp and power switch, and wiring board and motor that joins with it and control transformer are housed in this velometer.The fastening connection seat of nationality screw on this velometer, the circular drive sleeve that square hole is arranged in the installing one in this connection seat, and join with the square termination that is positioned at velometer, round-meshed coupling head, drive sleeve passes that connection seat and the square head shaft core of a flexible axle one end join and mat flexible axle nut is threaded with connection seat, and coupling head nationality holding screw and motor reel are affixed.

One coupling is made up of porose coupling head of axle sleeve, wherein the centre with screw and axle sleeve tightening and the axle that is with bearing, this flat upper end passes in the notch of the axle core that coupling head inserts flexible axle one end, and by the nut of flexible axle one end and being threaded of coupling head, this lower end is tightened up folder through spiral and is connected with stirring rod.The guide securement of axle sleeve periphery is applied mechanically that screw is fixed on the axle sleeve and is affixed with the connecting rod on top.

The utility model compared with prior art has following advantage: it is the flexible axle transmission that the utility model changes the direct transmission of original motor, attaching coupling on flexible axle, make the vertical adjusting of original heaviness become the adjusting dexterity conveniently, and combined integrated driving element and electronic speed regulation instrument, improved service efficiency widely.

The explanation of accompanying drawing drawing:

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is the line map of wiring board in the velometer.

Fig. 3 is the panel schematic diagram of velometer.

Following the utility model will describe in detail embodiment (in conjunction with the accompanying drawings).

Fig. 1 and the utility model shown in 3 include the platform 1 that has column 18, the flexible axle 19 and the velometer 25 of a

nut

9 and 20 are respectively arranged through

fixing slide block

15 and 17 connecting rods 14 and 16 that are connected with column 18, a stirring rod 2, two ends.The panel 35 of velometer 25 is provided with conversion stacked switch 32, indicator lamp 33 and power switch 34, the DC servo-motor 26 and the control transformer 30 that wiring board 31 are housed in the velometer 25 and join with it.

Nationality screw 23 fastening connection seats 24 on the velometer 25, the circular drive sleeve 21 that square hole is arranged in the installing one in this connection seat 24, this drive sleeve 21 is joined with the square termination, the round-meshed coupling head 29 that are positioned at velometer 25, drive sleeve 21 passes that connection seat 24 and the square head shaft core 191 of a flexible axle 19 1 ends join and nationality flexible axle nut 20 is threaded with connection seat 24, coupling head 29 nationality holding screws 22 and motor 26 spool affixed.

Coupling 5 is by axle sleeve 6, form with porose coupling head 8 in the screw 10 and the centre of axle sleeve 6 tightenings and the axle 12 that is with bearing 13, in the notch 192 of the axle core 191 of flat upper end 121 insertion flexible axles 19 1 ends of axle 12, and be threaded with coupling head 8 by the nut 9 of flexible axle 19 1 ends, the lower end of axle 12 is tightened up folder 4 through spiral and is connected with stirring rod 2.The guide securement of axle sleeve 6 peripheries cover 11 usefulness screws 7 are fixed on the axle sleeve 6 and are affixed with the connecting rod 14 on top.

The utility model is to realize speed change by the voltage that changes DC servo-motor 26 armature two ends.The line map of the wiring board 31 in the velometer 25 is seen Fig. 2, and the first edge joint 220V power supply of control transformer 30 is paid the limit and is divided into 10 grades, and 1 grade is 5V, and 2 grades is 10V, and 3 grades is 15V ... 10 grades is 80V.According to using needs, regulate conversion stacked switch 32, with the alternating current of different voltages through rectifier bridge ZLQ1 rectification, the power supply of rectifier bridge ZLQ2 is from upper and lower two taps of transformer 30, voltage is constant, for Exciting Windings for Transverse Differential Protection, capacitor C and resistance R constitute buffer circuit, RD after rectifier bridge ZLQ2 rectification ₁, RD ₂Be fusible link, holding circuit, motor 26 rotating speed adjustable extents 0～3000 are changeed.Along with the rotation of motor 26, the axle 12 and the stirring rod 2 that drive successively in coupling head 29, driving coupling cover 21, flexible axle 19, the coupling 5 are rotated.Unscrew screw 7, coupling 5 can overlap in 11 in guide securement and move up and down, and tightens screw 7 when being adjusted to correct position.
