Description

Technical Field

[0001] The present invention relates to the technical field of solid sample addition, and more specifically, to a split magnetic attraction type powder barrel, a powder barrel storage tank, and a solid sample addition instrument. Background Art

[0002] In many fields such as drug research and development, high-throughput screening, analysis and identification, material science, and catalyst research, the addition of trace amounts of liquid and solid samples is a common requirement. In order to automatically and accurately dispense trace amounts of liquid and powdered solid raw materials, high-precision quantitative sample addition instruments are usually used. Different from liquids, due to the diversity of the morphology and properties of solid powders, they lack fluidity and uniformity. At the same time, properties such as van der Waals forces and electrostatic forces show significant differences among different categories, making it difficult to ensure the sample addition accuracy and efficiency of various solid powders when using an automatic quantitative sample addition instrument.

[0003] The current mainstream solid sample addition method is to load solid powder into a powder barrel with a special structural design. Usually, a driving gear driven by a motor interacts with the powder barrel to achieve the effect of powder discharge. For the sample addition tasks of multiple powders, multiple powder barrels are usually required. Therefore, the volume of the powder barrel and the convenience of matching with the machine become particularly important.

[0004] The powder barrels used in the prior art need to use additional fixing parts to enable them to match the relative positions of the driving parts. Therefore, they are relatively large in volume and not easy to store. At the same time, the powder barrels are designed as consumables for long-term use, with complex structures and mostly made of metal rod materials, resulting in high costs. For the sample addition tasks of multiple powders, in order to avoid poor contamination, usually a large cleaning cost or the cost of purchasing new consumables is required. Summary of the Invention

[0048] The technical scheme of the present invention will be further described in detail below in conjunction with specific embodiments. It should be understood that the following embodiments are only exemplary descriptions and explanations of the present invention and should not be construed as limiting the scope of protection of the present invention. All technologies implemented based on the above content of the present invention are included in the scope that the present invention is intended to protect.

[0049] The present embodiment provides a split magnetic powder barrel, comprising: a driving part and a powder barrel part magnetically connected to the driving part; wherein the powder barrel part is used to store solid powder, and the driving part is used to drive the powder rod inside the powder barrel part to rotate to control the powder output. Since the powder barrel part needs to be replaced frequently in practice, and the driving part is a durable part, the present embodiment designs the driving part and the powder barrel part separately, and the two are connected by a quick-connect method. Specifically, the magnetic method of the present embodiment can be used to achieve quick connection, and this magnetic connection method has a directional effect.

[0050] See also Figures 1 - 7, the driving part includes a housing 10, a transmission wheel 11, a transmission rod 12, a first magnetic component 13 and a capping 14. The capping 14 is arranged at the upper end of the housing 10. The transmission wheel 11 is in transmission connection with the transmission rod 12. The transmission wheel 11 is arranged at the first end of the housing 10. The first magnetic component 13 is arranged at the second end of the housing 10. The first end and the second end are arranged opposite to each other. The transmission rod 12 passes through the housing 10 and extends out from the second end of the housing 10. The powder bucket part includes a bucket body 20, a bucket cover 21, a powder rod 22 and a second magnetic component 23. The bucket body 20 is used to hold solid powder. The bucket cover 21 is hermetically connected to the upper end of the bucket body 20. The lower end of the bucket body 20 has a powder outlet 201. The powder rod 22 is arranged inside the bucket body 20. The first end of the powder rod 22 is arranged in the central hole of the bucket cover 21 and can rotate relative to the central hole of the bucket cover 21. The second end of the powder rod 22 cooperates with the powder outlet 201 to control the powder output of the solid powder. The second magnetic component 23 is arranged on the bucket cover 21 and is magnetically attracted to the first magnetic component 13. When the second magnetic component 23 is magnetically attracted to the first magnetic component 13, the transmission rod 12 is in transmission connection with the powder rod 22.

[0051] Through the mutual cooperation of the second magnetic component 23 and the first magnetic component 13, the quick connection of the driving part and the powder bucket part can be realized, and the connection position is accurate. At the same time, after connection, the transmission rod 12 is in transmission connection with the powder rod 22. The transmission wheel 11 transmits power to the powder rod 22 through the transmission rod 12, and the rotation of the powder rod 22 controls the powder output.

[0052] Adopting the split magnetic powder bucket method can solve the positioning problem in automatic equipment, avoid using large-sized accessories, and at the same time, the designed small bucket body 20 is convenient for access and can prevent the solid powder from oxidation and moisture absorption.

[0053] In some embodiments, the first magnetic component 13 includes a plurality of first magnets. The plurality of first magnets are arranged in a circular array centered on the transmission rod 12, and any two adjacent first magnets have opposite polarities. The second magnetic component 23 includes a plurality of second magnets. The plurality of second magnets are arranged in a circular array centered on the powder rod 22, and any two adjacent second magnets have opposite polarities. The plurality of first magnets and the plurality of second magnets are in one-to-one correspondence and are in a mutually attracting state.

[0054] The driving part is as Figure 3 and Figure 4 shown. This component is non-consumable and can be quickly connected to a variety of powder buckets through four reverse magnets at 90°. The orientation is corrected by magnetic force, making it more convenient to use. The bottom of the driving component also includes evenly arranged buffer damping members to prevent powder leakage caused by the rapid impact between the powder bucket part and the driving part. The movement mode of this driving part is rotation, with a relatively compact structure and easy to disassemble and replace.

[0055] In some embodiments, the barrel body 20 has a sample addition port 202, which is provided with a silica gel plug 24 and is located on the side of the barrel body 20. There are two ways to add solid powder into the barrel body 20. One is to open the barrel lid 21 and add from the top, and the other is to open the silica gel plug 24 and add from the side.

[0056] In some embodiments, stirring wires 222 are provided on the powder rod 22, and the stirring wires 222 are made of polytetrafluoroethylene. By providing the stirring wires 222, the solid powder in the barrel body 20 can be made more uniform, avoiding powder solidification and being beneficial to improving the accuracy of powder output. Using polytetrafluoroethylene stirring wires 222 and a powder rod 22 made of plastic material greatly reduces the cost of the powder barrel and makes the multi-category sample addition task more economical.

[0057] A powder blocking block 221 is provided at the second end of the powder rod 22, and the powder blocking block 221 has a plurality of U-shaped powder output grooves; the powder output port 201 includes a plurality of fan-shaped ports, and the plurality of U-shaped powder output grooves cooperate with the plurality of fan-shaped ports to control the output of solid powder.

[0058] In some embodiments, the upper end of the powder rod 22 has an internal hexagonal groove, and the end of the transmission rod 12 is a metal rod with an external hexagonal chamfer and can be inserted and driven with the upper end of the powder rod 22. Among them, the upper end surface of the powder rod 22 is flush with or lower than the upper end surface of the barrel lid 21.

[0059] In some embodiments, the barrel body 20, the barrel lid 21 and the powder rod 22 are all made of plastic material; specifically, the material of the barrel body 20 is PETG (polyethylene terephthalate-1,4-cyclohexanedimethanol ester) added with an antistatic agent. Thus, the solid powder in the barrel body 20 is not prone to generating static electricity, thereby ensuring the stability of powder output.

[0060] Exemplarily, an outwardly convex clamping edge 203 is provided at the top of the barrel body 20, and a clamping groove adapted to the outwardly convex clamping edge 203 is provided on the lower bottom surface of the barrel lid 21. The barrel lid 21 is hermetically connected to the barrel body 20 through the outwardly convex clamping edge 203 and the clamping groove.

[0061] In some embodiments, a circular shaft sleeve 25 is provided in the central hole of the barrel lid 21, and the first end of the powder rod 22 is arranged in the circular shaft sleeve 25; the lower end inside the barrel body 20 is rotationally matched with the powder blocking block 221. Through the joint restraint of the circular shaft sleeve 25 and the barrel body 20 on the powder rod 22, the upper and lower ends of the powder rod 22 are controlled to prevent eccentricity.

[0062] In some embodiments, buffer damping members are uniformly arranged at the bottom of the driving part, refer to Figure 4 , both ends of the transmission rod 12 are provided with ball bearings 121, and the ball bearings 121 are fixedly arranged relative to the housing 10; the stability of the rotation of the transmission rod 12 is ensured by the two ball bearings 121.

[0063] Furthermore, the housing 10 contains an annular magnet 18 for magnetic connection with a solid sample adding instrument. The annular magnet 18 is located at the side of the housing 10.

[0064] In some embodiments, a sandwich layer 15 is provided inside the housing 10. The sandwich layer 15 is fixed by the housing 10 and the screw cap 14. One of the ball bearings 121 is disposed in the sandwich layer 15 and is cooperatively fixed by a snap ring 19;

[0065] A gear transmission member 16 is fixedly provided at the center of the transmission wheel 11. The gear transmission member 16 is engaged with the transmission rod 12 through a "one"-shaped notch. The gear transmission member 16 is disposed on the screw cap 14 through a bearing to ensure the stable rotation of the gear transmission member 16.

[0066] In some embodiments, a light shielding sheet 17 is provided between the screw cap 14 and the transmission wheel 11. The light shielding sheet 17 rotates synchronously with the transmission wheel 11. The light shielding sheet 17 is used to cooperate with a photoelectric induction switch to determine the rotation angle and control the opening and closing state of the powder outlet 201.

[0067] Specifically, the light shielding sheet 17 has a plurality of light shielding teeth 171 for sensing the photoelectric induction switch. The number of the light shielding teeth 171 is the same as the number of the sector-shaped openings of the powder outlet 201; when any one of the light shielding teeth 171 is sensed by the photoelectric induction switch, the powder blocking block 221 can block all the sector-shaped openings; when the driving part is magnetically connected to the powder bucket part (i.e., the initial connection position), one of the light shielding teeth 171 is exactly sensed by the photoelectric induction switch; thus, when the light shielding sheet 17 rotates synchronously with the transmission wheel 11 to any position where one of the light shielding teeth 171 is sensed by the photoelectric induction switch, the powder blocking block 221 can block all the sector-shaped openings, so as to better control the powder output amount, and when the driving part and the powder bucket part are at the initial connection position, the powder will not flow out from the powder outlet 201.

[0068] In some embodiments, referring to Figure 2 and Figure 4 , a vibration assembly 40 is provided inside the housing 10. The vibration assembly 40 includes a vibration frame 41, a vibrator 42 and a vibration frame bearing 43. Among them, both the vibration frame 41 and the vibration frame bearing 43 are sleeved on the transmission rod 12 and can rotate relative to the transmission rod 12, so that the normal rotation of the transmission rod 12 is not affected after the installation of the vibration frame 41 and the vibration frame bearing 43. At the same time, the vibration of the vibrator 42 can be transmitted to the transmission rod 12 through the vibration frame 41, so as to transmit the vibration effect to the powder bucket part below, thereby achieving the effect of preventing powder jamming.

[0069] Furthermore, the vibration assembly 40 further includes a spring contact connector female seat 44. The spring contact connector female seat 44 is electrically connected to the vibrator 42 and can be electrically connected to the spring contact connector male seat on the solid sample dispenser to control parameters such as the movement mode, frequency, and amplitude of the vibrator 42.

[0070] Refer to Figure 8 , this embodiment further provides a powder bucket storage tank for storing the powder bucket part in any of the above embodiments, including: a tank body 30, a tank cover 31, an upper buffer pad 32, and a lower buffer pad 33; a rack structure is designed on the upper half of the tank body 30, and the rack structure can place the bucket cover 21 on the upper edge of the tank body and fix the direction; the upper buffer pad 32 is arranged on the tank cover 31, and the lower buffer pad 33 is arranged at the bottom inside the tank body 30; the tank cover 31 is connected to the tank body 30 in a covering manner; the upper buffer pad 32 and the lower buffer pad 33 are silicone pads with a polytetrafluoroethylene layer on the surface. The powder bucket storage tank can store the unused powder bucket part and ensure the sealing performance, thereby avoiding the dampness or contamination of the solid powder. At the same time, the powder bucket storage tank is convenient for access and can prevent the powder from oxidizing and absorbing moisture.

[0071] This embodiment further provides a solid sample dispenser, including the split magnetic powder bucket in any of the above embodiments.
