Description

Technical Field

[0001] This invention relates to the field of powder mixing equipment technology, specifically to a laboratory micro-powder mixing equipment. Background Technology

[0002] Powder mixing is a fundamental process in materials preparation, chemical production, pharmaceutical research and development, and precision laboratory studies. The uniformity, non-contamination, and operational adaptability of mixing directly affect product quality and the accuracy and repeatability of experimental results. Currently, most mainstream powder mixing equipment in the industry is large-scale industrial equipment, such as V-type mixers and three-dimensional motion mixers. These are designed to adapt to large-scale, high-volume production scenarios, enabling powder mixing at the kilogram or even ton level, and have played a crucial role in industrial mass production.

[0003] However, existing industrial-grade mixing equipment is significantly mismatched with the micro-mixing needs in laboratory and precision materials preparation fields, failing to meet the customized proportioning and mixing requirements for milligram-level micro-powders. Specific shortcomings are manifested in several aspects:

[0004] Firstly, existing mixing equipment is mainly used for kilogram-level and ton-level mixing, with a large single mixing volume. However, laboratory research often involves small-dose, customized formulation experiments, requiring the processing of milligram-level trace powders. When existing equipment is used in such scenarios, it is prone to uneven mixing and serious material residues, resulting in a large waste of powder raw materials, which cannot meet the precise experimental needs of laboratories.

[0005] Secondly, existing mixing equipment generally uses stirring rods, screws, and other stirring mechanisms for forced mixing. During the mixing process, the stirring components are in direct contact with the powder. On the one hand, this can easily cause wear on the stirring components, and the wear debris can mix into the powder, causing material contamination and affecting the purity of precision materials or experimental results. On the other hand, the presence of the stirring mechanism creates many cleaning dead spots inside the equipment, making subsequent cleaning difficult and easily causing cross-contamination between different batches of powder, further limiting its application in the field of precision material preparation.

[0056] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention are described clearly and completely. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0057] To achieve the above objectives, the present invention adopts the following technical solution: a laboratory micro-powder mixing device, comprising: a support assembly, which includes a base support 100, on the surface of the base support 100 a first support 200 and a second support 300, and a driving component 400 mounted on the outer side of the second support 300; a mixing assembly 500, which includes a mixing seat 510 rotatably disposed between the first support 200 and the second support 300, the mixing seat 510 having a material cavity 511 inside, the material cavity 511 having an inner... The component has multiple sets of insertion holes 530; the collision assembly 600 includes a ball 610, a pull rope 620 and a locking component 630, a through hole 540 is provided on one side of the insertion hole 530, the pull rope 620 passes through the through hole 540, the top of each pull rope 620 is connected to a ball 610, and the bottom of the pull ropes 620 in the same row are connected to the locking component 630; the cover assembly 700 includes a cover plate 710, the bottom surface of the cover plate 710 is in contact with a turnover plate 720, and the turnover plate 720 has multiple sets of elastic claws built in.

[0058] The mixing equipment includes the following modes: feeding mode, where the mixing tube 800 is placed in each insertion hole 530, and the locking component 630 pulls down to lock the pull rope 620 and the ball 610; covering mode, where the cover plate 710 covers the top of the material cavity 511 and presses down on the mixing tube 800, causing the locking component 630 to unlock and release the pull rope 620, and the elastic claw clamps and locks the mixing tube 800; mixing mode, where the mixing seat 510 flips to mix the powder in the mixing tube 800, and the ball 610 collides with the mixing tube 800 to improve the mixing uniformity; and unloading mode, where the cover plate 710 is removed and each set of mixing tubes 800 is taken out, and the locking component 630 resets and locks.

[0059] In the above scheme:

[0060] 1. The mixing base 510 has multiple sets of sockets 530 built in, which can simultaneously place multiple sets of mixing tubes 800 to realize the simultaneous mixing of multiple batches of trace powders. It is suitable for the needs of multiple experiments in the laboratory, greatly improves experimental efficiency, and avoids the tedious and time-consuming operation of a single set.

[0061] 2. The powder is turned over by the mixing seat 510 and can also be shaken horizontally by the bottom support component 100 to achieve multi-dimensional stirring and improve the mixing uniformity of the powder.

[0062] 3. The design of the collision component 600 has the following effects: In the waiting state, the locking component 630 can lock the pull rope 620, thereby locking the collision ball 610 and preventing the collision ball 610 from moving freely; when the cover plate 710 is closed, the locking component 630 can be unlocked, thereby releasing the collision ball 610, allowing the collision ball 610 to swing freely within a certain range. The collision ball 610 collides with the mixing tube 800, using the collision vibration to break up powder agglomeration, improve mixing uniformity, and reduce powder residue on the sealing plug 820 or the top of the tube 810.

[0063] 4. When the cover plate 710 is closed, it can automatically lock the mixing tube 800 and unlock the ball 610. When picking up materials, it can simultaneously bring out multiple sets of mixing tubes 800, which greatly reduces the intensity of manual operation. At the same time, after the material is unloaded, the operator can remove the turnover plate 720 and quickly transfer multiple sets of mixing tubes 800 to the next heating process.

[0064] In this embodiment, the base support component 100 includes a base 110, on which horizontal guide rails 111 are symmetrically mounted. A reciprocating moving plate 120 is slidably mounted on the top of the two sets of horizontal guide rails 111, and a bottom plate 121 is mounted on the surface of the reciprocating moving plate 120. A longitudinal bar 130 is provided in the middle of the bottom surface of the reciprocating moving plate 120, and a sliding groove 131 is opened inside the longitudinal bar 130. The longitudinal bar 130 is located between the two sets of horizontal guide rails 111.

[0065] A rotating shaft 140 is rotatably mounted inside the base 110. A driven gear 141 is provided at the bottom end of the rotating shaft 140, and a turntable 142 is provided at the top end of the rotating shaft 140. A sliding column 143 is provided on the side surface of the turntable 142. The sliding column 143 slides into the sliding groove 131. The turntable 142 is located between two sets of horizontal guide rails 111. A first motor 150 is provided on the bottom surface of the base 110 and meshes with the driven gear 141.

[0066] In the above scheme: the first motor 150 drives the rotating shaft 140 and the turntable 142 to rotate. Through the cooperation of the sliding column 143 and the sliding groove 131, the reciprocating moving plate 120 is driven to move smoothly back and forth along the horizontal guide rail 111, thereby driving the mixing seat 510 to shake horizontally. While compacting the powder, it causes the powder remaining on the inner wall of the sealing plug 820 and the tube 810 to fall down, reducing material waste and improving the density of powder mixing.

[0067] In this embodiment, the first support member 200 includes a first support plate 210, which is vertically disposed at one end of the surface of the base plate 121. The top end of the first support plate 210 is provided with an electric slip ring 220, and the inner conductive rod 221 of the electric slip ring 220 is connected to the mixing seat 510 through a flange.

[0068] In the above scheme: the electric slip ring 220 provides continuous power supply when the mixing seat 510 is flipped. The inner conductive rod 221 not only supports the mixing seat 510, but also stabilizes the current transmission, avoids the power supply line from getting tangled or broken, and ensures that the electromagnet 520 continuously attracts the cover plate 710, thus ensuring the stability of the flipping mixing process and not interrupting the mixing process.

[0069] In this embodiment, the top outer periphery of the material cavity 511 is provided with a mating groove 512, and the cover plate 710 is fitted into the mating groove 512. The mating groove 512 is symmetrically provided with mounting grooves 513. Each set of mounting grooves 513 is equipped with a set of electromagnets 520. The two sets of electromagnets 520 are electrically connected to the inner conductive rod 221.

[0070] In the above scheme: the mating groove 512 at the top of the material chamber 511 precisely matches the cover plate 710, guiding the cover plate 710 to quickly align and close, avoiding misalignment, and providing a precise positioning basis for the subsequent locking of the mixing tube 800 by the elastic claw and the pressing and unlocking of the ball 610, thus improving the ease of operation; after the electromagnet 520 is energized, it attracts the cover plate 710, achieving a firm connection between the cover plate 710 and the mixing seat 510, so that the cover plate 710 will not fall off or loosen when the mixing is flipped or shaken horizontally. The mechanism ensures the stability of the mixing tube 800 and prevents powder spillage. It also ensures that the cover plate 710 and the mixing seat 510 rotate synchronously. The positioning structure is simple and easy to pick up and put down. The electromagnet 520 is powered by the inner conductive rod 221 and can achieve continuous adsorption. When the cover plate 710 is pressed down, it fits into the mating groove 512 and accurately contacts the mixing tube 800 as it descends. This triggers the locking component 630 to unlock the ball 610, realizing the integrated linkage of closing the cover and unlocking the ball 610, and improving the continuity of the process.

[0071] In this embodiment, the locking component 630 includes a first lifting plate 631, a second lifting plate 635, and a linkage rod 633. The bottom ends of multiple sets of pull ropes 620 located in the same row are all connected to the first lifting plate 631. The bottom end of the first lifting plate 631 is provided with a first spring rod 632. The bottom of the insertion holes 530 in the same row is provided with a second lifting plate 635. The bottom end of the second lifting plate 635 is provided with a second spring rod 636. Multiple sets of linkage rods 633 are provided. The middle part of each set of linkage rods 633 is rotatably connected to a fixed plate 634. One end of the linkage rod 633 extends to the bottom of the first lifting plate 631, and the other end of the linkage rod 633 extends to the bottom of the second lifting plate 635. The first lifting plate 631 and the second lifting plate 635 move in opposite directions.

[0072] In the above scheme: the first lifting plate 631 and the second lifting plate 635 move in opposite directions through the linkage rod 633. When the cover plate 710 is pressed down, it drives the second lifting plate 635 to descend, which in turn drives the first lifting plate 631 to rise, automatically releasing the pull rope 620 and the ball 610. When picking up materials, the cover plate 710 rises, the spring rod drives the lifting plate to reset, and automatically locks the ball 610, eliminating the need for manual operation and improving efficiency. All pull ropes 620 in the same row are connected to the first lifting plate 631. Through the synchronous transmission of the linkage rod 633, the synchronous locking and releasing of multiple sets of balls 610 is achieved, avoiding deviations in the state of a single set of balls 610, ensuring that all mixing pipes 800 can be hit by the balls 610 during mixing, and improving the uniformity and consistency of mixing.

[0073] In this embodiment, the bottom surfaces of the cover plate 710 are magnetically connected to the electromagnet 520 on both sides. The bottom surface of the cover plate 710 is provided with a baffle frame 713. The center of the surface of the cover plate 710 is provided with a handle 712, and through holes are provided around the handle 712.

[0074] In the above scheme: the handle 712 on the surface of the cover plate 710 facilitates the quick handling of the cover plate 710 by the experimental personnel, improving the ease of operation; the enclosure frame 713 can accurately limit the turnover plate 720, prevent the turnover plate 720 from shifting at the bottom of the cover plate 710, and ensure that the elastic claws are accurately connected with the mixing pipe 800; the through hole corresponds to the screw hole 721 of the turnover plate 720, which facilitates the fixing of the turnover plate 720 by the locking knob 711, and the connection is firm.

[0075] In this embodiment, the turnover plate 720 is fitted into the area enclosed by the enclosure frame 713. The turnover plate 720 has screw holes 721 inside, which are located below the through hole. The cover plate 710 is connected to the turnover plate 720 through a locking knob 711. The bottom surface of the turnover plate 720 is provided with multiple sets of docking discs 730. Each set of docking discs 730 corresponds to a set of mixing pipes 800. The bottom surface of the docking discs 730 is provided with multiple sets of elastic claws 731.

[0076] In the above scheme: the docking plate 730 corresponds one-to-one with the mixing tube 800, and the elastic claw 731 can firmly clamp the mixing tube 800. When picking up the material, the cover plate 710 drives the turnover plate 720 to rise synchronously, bringing out multiple sets of mixing tubes 800 at one time, eliminating the need for manual handling and greatly improving material picking efficiency. The elastic claw 731 clamps the mixing tube 800 by deformation, ensuring a firm grip without damaging the mixing tube 800. During the transfer process, the mixing tube 800 will not loosen or tip over, avoiding powder spillage and ensuring experimental accuracy and material utilization. The turnover plate 720 can be quickly separated from the cover plate 710. After separation, it can directly carry multiple sets of mixing tubes 800 to the next experimental station, realizing the unified turnover of multiple sets of mixing tubes 800, adapting to the needs of multiple batches and continuous experiments in the laboratory, and reducing the frequency of manual transfer.

[0077] In this embodiment, the mixing tube 800 includes a tube body 810 and a sealing plug 820. The top sidewall of the tube body 810 is provided with an outer ring body 811, and the top of the tube body 810 is covered by a stepped sealing plug 820. Multiple sets of elastic claws 731 engage with the bottom of the outer ring body 811. The outer ring body provides precise clamping points for the elastic claws 731, which can engage with the bottom of the outer ring body 811, achieving a secure connection between the mixing tube 800 and the transfer plate 720, preventing the mixing tube 800 from falling off or shifting during transfer and mixing.

[0078] In this embodiment, the second support member 300 includes a second support plate 310, and the driving component includes a second motor 420 and a coupling 430. The second support plate 310 is vertically disposed on the other end of the surface of the base plate 121. A drive shaft 311 is rotatably mounted on the top of the second support plate 310. One end of the drive shaft 311 is connected to the mixing seat 510 through a flange, and the other end of the drive shaft 311 is connected to the coupling 430. A third support plate 410 is provided at intervals on the outer side of the second support plate 310. The second motor 420 is provided on the top outer wall of the third support plate 410, and the output end of the second motor 420 is connected to the coupling 430.

[0079] In the above scheme: the second motor 420 drives the drive shaft 311 to rotate through the coupling 430, the power transmission is smooth and the mixing uniformity is improved; the drive shaft 311 is connected to the mixing seat 510 through the flange, the connection is tight and firm and will not loosen even after long-term use; the second support plate 310 and the third support plate 410 provide firm support for the drive component 400 and reduce shaking during driving.

[0080] In this embodiment, the inner wall of the second support plate 310 is provided with a position sensor 320, and the bottom surface of the mixing seat 510 is provided with a calibration plate 550.

[0081] Working principle and usage process of this invention:

[0082] S1, Mixing pipe 800 placement:

[0083] The experimenter loads the powder to be mixed into the tube body 810 of the mixing tube 800, and then covers it with the sealing plug 820; inserts each mixing tube 800 into the insertion hole 530, at which point the mixing tube 800 is placed against the top surface of the second lifting plate 635; repeats the above actions to complete the placement of each mixing tube 800.

[0084] At this time, the first lifting plate 631 is at the bottom and the second lifting plate 635 is at the top. The first lifting plate 631 pulls down multiple sets of ropes 620 in a taut state. In this way, each set of touching balls 610 can be positioned to prevent the touching balls 610 from rolling freely.

[0085] S2, Cover plate 710 closed:

[0086] The cover plate 710 is inserted into the mating groove 512. The electromagnet 520 is energized to attract the cover plate 710. During the insertion process, the elastic claws 731 at the bottom of each turnover plate 720 deform and engage with the mixing pipe 800. Then the cover plate 710 continues to press down, which will abut against each mixing pipe 800 as it descends. The mixing pipe 800 abuts against the second lifting plate 635 as it descends and compresses the second spring rod 636. The second lifting plate 635 presses down on one end of the linkage rod 633, causing the other end of the linkage rod 633 to pry up the first lifting plate 631. The first lifting plate 631 moves upward and stretches the first spring rod 632. Each set of pull ropes 620 loses its downward pull and loosens, allowing the ball 610 to swing freely within a certain range.

[0087] S3, Tilting and Mixing:

[0088] The second motor 420 drives the coupling 430 and the drive shaft 311 to rotate, thereby causing the mixing seat 510 and the cover plate 710 to rotate synchronously. The inner conductive rod 221 follows the rotation and keeps supplying power to the electromagnet 520.

[0089] The powder in each mixing tube 800 is turned over and mixed. During the turning process, the ball 610 will move and collide with each mixing tube 800. The rope 620 can restrict the movement range of the ball 610, thereby improving the mixing efficiency and uniformity.

[0090] S4, Horizontal Swaying:

[0091] After the flipping is completed, the calibration plate 550 moves into the position sensor 320, the second motor 420 stops working, and the mixing seat 510 is in a horizontal state;

[0092] The first motor 150 drives the driven gear 141 to rotate, the driven gear 141 drives the rotating shaft 140 to rotate, the rotating shaft 140 drives the top turntable 142 to rotate, the turntable 142 drives the sliding column 143 to move longitudinally in the sliding groove 131, and finally drives the contact strip 130, the reciprocating moving plate 120 and the bottom plate 121 to move horizontally back and forth along the horizontal guide rail 111, and finally realize the horizontal reciprocating motion of the mixing seat 510. During the reciprocating motion, the mixing tube 800 shakes and compacts the powder, and the ball 610 collides with the tube wall of the mixing tube 800, causing the powder remaining on the top of the sealing plug 820 and the inner wall of the tube body 810 to fall, improving the compactness of the powder and reducing the adhesion of the bottom surface of the sealing plug 820.

[0093] S5, Material Retrieval:

[0094] After the horizontal shaking ends, the electromagnet 520 is de-energized. The cover plate 710 is lifted by the handle 712. When the cover plate 710 is lifted, the turnover plate 720 is lifted accordingly. The elastic claws in the turnover plate 720 clamp the mixing tube 800 and lift it accordingly, so as to realize the unified picking of multiple mixing tubes 800 without the need for manual picking one by one.

[0095] During the lifting process of the cover plate 710 and the mixing pipe 800, the second lifting plate 635 loses downward pressure, the second spring rod 636 drives the second lifting plate 635 to lift, the linkage rod rotates to reset, the first spring rod 632 drives the first lifting plate 631 to descend, and the first lifting plate 631 pulls down each pull rope 620 to a taut state, so as to ensure that the position of the ball 610 remains unchanged.

[0096] S6, turnover board 720 separation:

[0097] By unscrewing each locking knob 711, the transfer plate 720 is detached from the cover plate 710. The operator can then quickly transfer multiple mixing tubes 800 to the next heating station via the transfer plate 720, achieving unified transfer without the need to remove and transfer them individually.
