Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0021] Please refer to Figures 1-4 , the present utility model provides a technical solution: a medicine mixing device for biomedical research, including a bottom plate 1, a non-slip pad 2 is fixedly connected to the lower surface of the bottom plate 1, and on the upper
[0022] surface of the bottom plate 1, a column 3 is fixedly connected, on the upper surface of the column 3, a panel 4 is fixedly connected, a quantitative mechanism 5 is arranged on the upper surface of the panel 4, and a mixing mechanism 6 is arranged on one side surface of the column 3; the quantitative mechanism 5 includes a connecting block 501, a hose 502, a clamping block 503, a discharge head 504, a sliding groove 505, a sliding block 506, a pulling block 507, a measuring cylinder 508, a conical groove 509, an observation port 510 and scale lines 511. A connecting block 501 is fixedly connected to the upper surface of the panel 4, a hose 502 is fixedly connected to the lower surface of the connecting block 501, a clamping block 503 is fixedly connected to the outer surface of the hose 502, one end of the hose 502 is fixedly connected to a discharge head 504, a sliding groove 505 is opened on the upper surface of the connecting block 501, a sliding block 506 is slidably connected to the inner surface of the sliding groove 505, a pulling block 507 is fixedly connected to one side surface of the sliding block 506, a measuring cylinder 508 is fixedly connected to the upper surface of the connecting block 501, a conical groove 509 is opened on the inner surface of the measuring cylinder 508, an observation port 510 is fixedly connected to the outer surface of the measuring cylinder 508, and scale lines 511 are fixedly connected to the outer surface of the measuring cylinder 508. Through the settings of the connecting block 501, the hose 502, the clamping block 503, the discharge head 504, the sliding groove 505, the sliding block 506, the pulling block 507, the measuring cylinder 508, the conical groove 509, the observation port 510 and the scale lines 511, when in use, first clamp the clamping block 503 into the feed inlet 605 to fix the hose 502 and the discharge head 504, then pour the medicine into the conical groove 509 in the measuring cylinder 508. This shape design is beneficial for the medicine to be concentrated at the bottom for more accurate measurement. The liquid level of the medicine inside the measuring cylinder 508 can be directly observed through the observation port 510, and the scale lines 511 clearly mark the volume of the medicine, so that the addition amount of the medicine can be accurately controlled according to the needs of the experiment or mixing. Then pull the pulling block 507 to drive the sliding block 506 to slide inside the sliding groove 505, so that the sliding block 506 no longer blocks the injection port. The medicine will pass through the connecting block 501 and the hose 502 in sequence and finally be discharged from the discharge head 504 and enter the mixing tank 603, realizing quantitative operation and improving the accuracy of biomedical research.
[0023] Furthermore, multiple groups of non-slip pads 2 are arranged on the lower surface of the bottom plate 1, and the columns 3 are symmetrically arranged with respect to the central axis of the panel 4. Through the setting of the non-slip pads 2, when in use, the non-slip pads 2 can increase the friction between the bottom plate 1 and the tabletop, ensuring the safety and accuracy of the operation.
[0024] Furthermore, the connecting block 501 is symmetrically arranged with respect to the central axis of the panel 4. The inner dimension of the sliding groove 505 matches the outer dimension of the sliding block 506. Through the arrangement of the sliding groove 505 and the sliding block 506, during use, the sliding block 506 slides inside the sliding groove 505, and the sliding groove 505 limits the sliding block 506, making the sliding of the sliding block 506 more stable.
[0025] Furthermore, the mixing mechanism 6 includes a servo motor 601, a rotating shaft 602, a mixing tank 603, a top plate 604, a feed inlet 605, a sealing cover 606, a driving motor 607, a stirring shaft 608, stirring blades 609, crushing columns 610, and a discharge port 611. One side surface of the column 3 is fixedly connected to a servo motor 601, one side surface of the servo motor 601 is fixedly connected to a rotating shaft 602, one end of the rotating shaft 602 is fixedly connected to a mixing tank 603, the upper surface of the mixing tank 603 is fixedly connected to a top plate 604, the upper surface of the top plate 604 is fixedly connected to a feed inlet 605, the upper surface of the feed inlet 605 is rotatably connected to a sealing cover 606, the upper surface of the top plate 604 is fixedly connected to a driving motor 607, the lower surface of the driving motor 607 is fixedly connected to a stirring shaft 608, the outer surface of the stirring shaft 608 is fixedly connected to stirring blades 609, the outer surface of the stirring shaft 608 is fixedly connected to crushing columns 610, and the lower surface of the mixing tank 603 is fixedly connected to a discharge port 611. Through the servo motor 601, the rotating shaft 602, the mixing tank 603, the top plate 604, the feed inlet 605, the sealing cover 606, the driving motor 607, the stirring shaft 608, the stirring blades 609, the crushing columns 610, and the discharge port
[0026] For the setting of 611, during use, open the sealing cover 606 above the feed inlet 605, and put the medicines to be mixed into the interior of the mixing tank 603 through the feed inlet 605. The sealing cover 606 can seal the mixing tank 603 after the feeding is completed, preventing the material from splashing out during the mixing process and the entry of external impurities. Then start the driving motor 607. The driving motor 607 starts to work and drives the stirring shaft 608 to rotate. The stirring blades 609 on the outer surface of the stirring shaft 608 perform a stirring action in the mixing tank 603 as the stirring shaft 608 rotates, so that the materials at different positions are fully mixed to ensure the uniformity of mixing. At the same time, the crushing columns 610 outside the stirring shaft 608 also rotate together with the stirring shaft 608. During the mixing process, there may be cases of caking or larger particles. The crushing columns 610 use the impact force and frictional force generated by their rotation to impact and crush these caked or large particles, making them into finer particles for better mixing with other materials evenly. When it is necessary to adjust the angle of the mixing tank 603 or perform some special mixing operations, start the servo motor 601. The servo motor 601 works and drives the rotating shaft 602 to rotate. The rotating shaft 602 then drives the mixing tank 603 fixedly connected thereto to rotate. By precisely controlling the rotation speed and rotation angle of the servo motor 601, the position and posture of the mixing tank 603 can be flexibly adjusted to meet the requirements of different mixing processes. When the mixing is completed, open the discharge port 611 on the lower surface of the mixing tank 603. The evenly mixed material flows out from the discharge port 611 under the action of its own gravity and enters the next technological process or storage container.
[0027] Furthermore, the rotating shaft 602 is symmetrically arranged with respect to the central axis of the top plate 604. The outer dimension of the clamping block 503 matches the inner dimension of the feed inlet 605. Through the settings of the clamping block 503 and the feed inlet 605, during use, the clamping block 503 is clamped into the feed inlet 605, which can fix the hose 502 and the discharge head 504 to make the feeding more stable.
[0028] Furthermore, the feed inlet 605 is symmetrically arranged with respect to the central axis of the top plate 604. The feed inlet 605 and the sealing cover 606 form a sealing structure. Through the setting of the feed inlet 605, during use, a quantitative mechanism 5 is provided on multiple groups of feed inlets 605, and different medicines can be added quantitatively.
[0029] Furthermore, multiple groups of stirring blades 609 are evenly distributed on the outer surface of the stirring shaft 608 at equal intervals, and multiple groups of crushing columns 610 are evenly distributed on the outer surface of the stirring shaft 608 at equal intervals. Through the setting of the crushing columns 610, during use, the crushing columns 610 use the impact force and frictional force generated by their rotation to impact and crush these caked or large particles, making them into finer particles for better mixing with other materials evenly.
[0030] Working principle: Open the sealing cover 606 above the feed inlet 605, insert the clamping block 503 into the feed inlet 605, fix the hose 502 and the discharge head 504, and then pour the medicine into the conical groove 509 in the measuring cylinder 508. This shape design is conducive to concentrating the medicine at the bottom for more accurate measurement. The liquid level of the medicine inside the measuring cylinder 508 can be visually observed through the observation port 510, and the scale line 511 clearly marks the volume of the medicine. Thus, the addition amount of the medicine can be precisely controlled according to the needs of the experiment or mixing. Then, pull the pulling block 507 to drive the sliding block 506 to slide inside the sliding groove 505, so that the sliding block 506 no longer blocks the filling port. The medicine will pass through the connecting block 501 and the hose 502 in sequence and finally be discharged from the discharge head 504 and enter the mixing tank 603, realizing quantitative operation and improving the accuracy of biomedical research. After the medicine is put into the mixing tank 603 through the feed inlet 605, the sealing cover 606 is closed to seal the mixing tank 603, preventing the material from splashing out during the mixing process and external impurities from entering. Then, start the driving motor 607. The driving motor 607 starts to work and drives the stirring shaft 608 to rotate. The stirring blades 609 on the outer surface of the stirring shaft 608 perform stirring actions inside the mixing tank 603 as the stirring shaft 608 rotates, making the materials at different positions fully mixed to ensure the uniformity of mixing. At the same time, the crushing columns 610 outside the stirring shaft 608 also rotate together with the stirring shaft 608. During the mixing process, there may be cases of caking or larger particles. The crushing columns 610 use the impact force and friction generated by their rotation to impact and crush these caking or large particles, making them into finer particles for better mixing with other materials. When it is necessary to adjust the angle of the mixing tank 603 or perform some special mixing operations, start the servo motor 601. The servo motor 601 works and drives the rotating shaft 602 to rotate. The rotating shaft 602 then drives the mixing tank 603 fixedly connected to it to rotate. By precisely controlling the rotation speed and rotation angle of the servo motor 601, the position and attitude of the mixing tank 603 can be flexibly adjusted to meet the requirements of different mixing processes. When the mixing is completed, open the discharge port 611 on the lower surface of the mixing tank 603. The uniformly mixed material flows out from the discharge port 611 under the action of its own gravity and enters the next process flow or storage container. Among them, the models of the servo motor 601 and the driving motor 607 are YE2-132S-4.
