Specific embodiments

[0037] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention;

[0038] Refer to Figure 1-10 , a fully automated volumetric flask mixer, including a bottom plate 1 and a volumetric flask 4. It is characterized in that two columns 2 are installed on the bottom plate 1, and a main shaft 6 and a sub-shaft 7 are rotatably installed between the two columns 2 from bottom to top. A reduction motor 3 is installed on the bottom plate 1, and the drive shaft of the reduction motor 3 and the main shaft 6 are driven through a pulley drive assembly 5;

[0039] The pulley drive assembly 5 includes a driving pulley, a driven pulley and a belt. The driving pulley is installed on the drive shaft of the reduction motor 3, the driven pulley is installed on the main shaft 6, and the driving pulley and the driven pulley are connected by a belt. Among them, the diameter of the driving pulley is smaller than the diameter of the driven pulley.

[0040] When the reduction motor 3 drives, it can directly drive the driving pulley to rotate, and use the belt to control the rotation of the driven pulley, so as to provide power for the main shaft 6, so that it can rotate relative to the column 2.

[0041] One end of the main shaft 6 and the sub-shaft 7 close to the reduction motor 3 are driven by a crank 8, a connecting rod 9 and a first rocker arm 10. One end of the crank 8 is vertically fixed to the end of the main shaft 6, the other end of the crank 8 is rotatably installed with one end of the connecting rod 9, the other end of the connecting rod 9 is rotatably installed with one end of the first rocker arm 10, and the other end of the first rocker arm 10 is vertically fixed to the end of the sub-shaft 7. Two second rocker arms 11 are vertically fixed on the sub-shaft 7, and a support plate 12 is commonly fixed at one end of the two second rocker arms 11 far from the sub-shaft 7;

[0042] When the main shaft 6 rotates, the crank 8 makes a complete circular motion, and under the cooperation of the connecting rod 9, it can drive the first rocker arm 10, the second rocker arm 11 and the support plate 12 to make a reciprocating swinging motion. After the support plate 12 and the volumetric flask 4 swing, they can present the states shown in Figure 3 and Figure 4 , so as to repeatedly shake the volumetric flask up and down, and the solution can be mixed.

[0043] Above the side of the support plate 12 close to the column 2, a screw drive motor 14, a screw 15, and a first sliding seat 16 are installed.

[0044] The screw drive motor 14 is fixedly installed on the support plate 12, and the drive shaft of the screw drive motor 14 is fixedly connected to one end of the screw 15. The screw 15 is rotatably installed on the support plate 12 through a bearing. The screw 15 is threadedly installed with the first sliding seat 16. The first sliding seat 16 is provided with a threaded hole matching the screw 15. A through groove is provided above the support plate 12. An extension plate 18 extending to the other side of the through groove is installed on the first sliding seat 16. A pressing plate 19 is installed at one end of the extension plate 18 away from the first sliding seat 16. A plurality of bottle cap fixing components 24 are installed below the pressing plate 19; a fixing rod 20 is also installed below the pressing plate 19.

[0045] Below the side of the support plate 12 away from the column 2, a second sliding seat 21, a bottle body fixing component 22, and a base 13 are installed; the lower end of the fixing rod 20 is connected to the second sliding seat 21, and a plurality of bottle body fixing components 22 are detachably installed on the second sliding seat 21.

[0046] The base 13 is detachably fixedly installed on the support plate 12, and the bottom of the volumetric flask 4 is placed on the base 13. Refer to Figure 10 As shown, the base 13 has a variety of different specifications and forms, so as to facilitate the adaptation to volumetric flasks 4 of different specifications for use; in this embodiment, the base 13 is fixedly installed on the support plate 12 by means of bolts.

[0047] Among them, the first sliding seat 16 is slidably installed with the first sliding rail 17, and the first sliding rail 17 is fixedly installed on the support plate 12.

[0048] Among them, the second sliding seat 21 is slidably installed with the second sliding rail 23, and the second sliding rail 23 is fixedly installed on the support plate 12.

[0049] Further, the bottle cap fixing component 24 includes a sleeve. The top of the sleeve is detachably fixedly installed on the pressing plate 19 by bolts. The specification of the sleeve is replaced according to the specification of the volumetric flask 4. An elastic pressing block 240 is installed inside the sleeve. A bottle cap 40 is provided at the mouth of the volumetric flask 4. The sleeve is sleeved on the mouth of the volumetric flask 4, and the lower end of the elastic pressing block 240 abuts against the top surface of the bottle cap 40. The bottle cap fixing component 24 can be applicable to volumetric flasks 4 and bottle caps 40 of different specifications, and can be pressed and positioned from top to bottom.

[0050] Further, the bottle body fixing component 22 includes a U-shaped clamping seat. The U-shaped clamping seat has two arc-shaped claws 220, and elastic pressing pads 221 are fixed on the bottom surfaces of the two arc-shaped claws 220. As Figure 10As shown, specifically, the U-shaped holder is detachably mounted with the second slide seat 21 by bolts, and the bottle fixing assembly 22 of different specifications can be replaced, so that the bottle fixing assembly 22 can achieve an effective bottle fixing effect when replacing the volumetric flask 14 of different specifications; ensuring the safety and stability of the volumetric flask 14 during the mixing process. Figure 10 In the figure, the two volumetric bottles 14 on the left are smaller than the two volumetric bottles 14 on the right, so the two bottle body fixing assemblies 22 on the left are also smaller than the two bottle body fixing assemblies 22 on the right.

[0051] Further, the top surface of the base 13 is provided with a groove matching the bottom of the volumetric flask 4. The arrangement of the groove can better place the volumetric flask 4 and achieve a stable supporting effect on the bottom of the bottle.

[0052] The reduction motor 3 and the screw drive motor 14 are connected to the host externally, and are used for driving and setting motion parameters of each motor. When in use, the volumetric flask 4 is placed on the base 13, and the speed and time of the reduction motor 3 can be set according to the properties of the liquid to achieve the corresponding operation. The host sends a command and the device starts to work. The screw drive motor 14 drives the screw 15 to rotate, and controls the first slide 16, the extension plate 18, the pressure plate 19, the fixed rod 20, the second slide 21, the bottle body fixing assembly 22, and the bottle cap fixing assembly 24 to move down along the bracket plate 12 at the same time, wherein the bottle cap fixing assembly 24 can cover the bottle mouth of the volumetric flask 4, and the lower end of the elastic pressure block 240 is against the top surface of the bottle cap 40, so that the bottle cap 40 can be pressed, and at the same time, the arc claw 220 of the bottle body fixing assembly 22 cooperates with the elastic pressure pad 221 to press the bottle body of the volumetric flask 4, so that the volumetric flask 4 can be stably positioned on the bracket plate 12, and then the mixing operation is performed.

[0053] By utilizing the driving effect of the reduction motor 3, the support plate 12 and the volumetric flask 4 can be controlled to perform repeated up and down swinging movements, and they can swing up and down 90 degrees, thereby achieving a mixing effect on the internal solution.

[0054] Among them, the elastic pressure pad 221 and the elastic pressure block 240 can both be made of rubber material, which can not only avoid achieving stable pressing pressure on the bottle body and bottle cap 40 of the volumetric flask 4, but also increase friction, and also avoid damage to the bottle body, ensuring safety during mixing.

[0055] The invention can realize artificial mixing operation on volumetric flasks, and can be adapted to the mixing operation of 5ml, 10ml, 20ml, 25ml, 50ml, 100ml, 150ml, 200ml, 250ml and even larger volumetric flasks of 500ml and 1000ml.
