Description

Technical Field

[0001] The present application relates to the technical field of automatic intelligent powder adding equipment, and in particular to an automatic powder feeding equipment. Background Art

[0002] In the fields of chemical technology and biotechnology, powder or liquid addition is often required to meet various sample addition requirements in the experiment. The addition actions are frequent and the powder dosage accuracy requirements are high.

[0003] In the prior art, manual sampling, handheld powder sampling, and semi-automatic powder sampling are usually used for sampling. Among them, manual sampling is to manually take a spoonful of powder and place it on the powder receiving tray of the milligram-level electronic scale, and gently hit the spoon with your fingers to make the powder fall into the powder receiving tray of the electronic scale little by little. Long-term operation can easily cause visual fatigue. Therefore, this method is not only inefficient but also difficult to control the amount of powder added; handheld powder sampling is to manually use a handheld powder sampler for sampling. In this process, although tools are used to assist the operation, the powder adding efficiency can be improved to a certain extent, the powder adding amount cannot be accurately controlled; semi-automatic powder sampling is to manually place the reinforcer and reaction bottle filled with powder in a fixed position of the machine, and use the machine to perform powder sampling. After the completion, the bottle is taken out. Only one reinforcer or one reaction bottle can be placed at a time. Although this method can meet the requirements of accurate powder addition to a certain extent, the powder addition amount is at the milligram level, so the electronic scale is very sensitive. A small amount or the impulse generated when the powder falls can also affect the reading of the electronic scale. In addition, since the reading of the electronic scale is real-time, there will be some powder in the air that has not fallen after the reading of the electronic scale reaches the required value. When the powder falls, it will exceed the required value, or the actual weight of the powder will be less than the reading of the electronic scale due to the impulse, which cannot meet the requirements of accurate powder addition. It has the disadvantages of low sample addition efficiency, low degree of automation, and low powder addition accuracy.

[0004] Therefore, there is an urgent need for an automated powder feeding equipment with high automation, high sample adding efficiency and precise powder adding amount control. Summary of the Invention

For those skilled in the art, the specific meanings of the above terms in this application can be specifically understood.

[0043] Figure 1 This is a schematic diagram of the overall structure of an automated powder feeding device for this application. For ease of description, the directions involved in this application are as follows: Figure 1 The direction shown is subject to Figure 1 As shown, an automatic powder feeding device includes a sample feeding module, a weighing device 5, and an electrical cabinet 6. The electrical cabinet 6 is used to realize signal transmission and electrical control between the weighing device 5 and the sample feeding module. The sample feeding module cooperates with the weighing device 5 to perform powder feeding.

[0044] The sample adding module includes a displacement drive module 1, a sample adding drive device 2, a sample feeder 3, and a powder receiving trough assembly 4. The sample adding drive device 2, the sample feeder 3, and the powder receiving trough assembly 4 are connected to the same side of the displacement drive module 1. The displacement drive module 1 drives the sample adding drive device 2 and the sample feeder 3 to move up and down along the Z direction to coordinate feeding.

[0045] The sampler 3 can be used to store materials to be sampled therein. A sample outlet 301 is provided at the lower portion of the sampler 3 , and materials can be discharged from the sampler 3 through the sample outlet 301 .

[0046] The reaction bottle socket of the weighing device 5 is arranged below the sample outlet 301 of the sample injector 3 . A reaction bottle is placed in the reaction bottle socket for weighing the weight of the material added into the reaction bottle by the sample injector 3 through the weighing device 5 .

[0047] The powder receiving trough assembly 4 is arranged between the sample feeder 3 and the weighing device 5. The electrical cabinet 6 controls the powder receiving trough assembly to move back and forth along the Y direction below the sample outlet 301 according to the weighing signal of the weighing device 5, so that the powder receiving trough assembly moves toward or away from the sample outlet 301.

[0048] Specifically, Figure 2 This is a schematic diagram of the structure of the weighing device 5 in this application, as shown in FIG. Figure 2 As shown, the weighing device 5 includes a reaction bottle guide 51, a cover body 52 and a weighing module. The weighing module is installed in the cover body 52. ​​The reaction bottle guide 51 is arranged above the cover body 52. ​​The reaction bottle guide 51 includes a positioning hole 511 that passes through in the axial direction. The positioning hole 511 is coaxially arranged with the reaction bottle socket of the weighing module, and is used to limit the reaction bottle connected to the reaction bottle socket to avoid the occurrence of reaction bottle position offset during the automated powder feeding process.

[0049] Figure 3 This is a schematic diagram of the structure of the weighing module in this application, such as Figure 3 As shown, the weighing module includes an electronic scale mounting bracket 53, an electronic scale 54, and a reaction bottle carrier 55. The reaction bottle carrier 55 is connected to the top of the electronic scale 54. A reaction bottle socket for accommodating a reaction bottle is provided above the reaction bottle carrier 55. The reaction bottle socket is located below the sample outlet 301 of the sampler 3.

[0050] In some preferred embodiments, the electronic scale 54 is a milligram-level electronic scale for improving the sensitivity and accuracy of weighing.

[0051] Specifically, such as Figure 1 As shown, the displacement drive module 1 includes a Y-axis drive module 11 and a displacement support seat 12. The sample loading drive device 2 and the sample loader 3 are connected to the same side of the displacement support seat 12. The displacement support seat 12 is connected to the output end of the Y-axis drive module 11 and is used to drive the sample loading drive device 2 and the sample loader 3 to move along the Y direction through the Y-axis drive module 11.

[0052] In some preferred embodiments, the displacement drive module 1 also includes a first Z-axis drive module 13 and a Z-axis drive module slider mounting plate 14. The Z-axis drive module slider mounting plate 14 is slidably connected to the upper part of the displacement support seat 12 through the first Z-axis drive module 13. The sample loading drive device 2 and the sample loader 3 are connected to the output end of the first Z-axis drive module 13 through the Z-axis drive module slider mounting plate 14, and are used to drive the sample loading drive device 2 and the sample loader 3 to move along the Z direction through the first Z-axis drive module 13.

[0053] Furthermore, the displacement drive module 1 also includes a second Z-axis drive module 15, and the sample loading drive device 2 is connected to the top of the Z-axis drive module slider mounting plate 14 through the second Z-axis drive module 15. The sample loading drive device 2 is connected to the output end of the second Z-axis drive module 15. Under the driving action of the second Z-axis drive module 15, the sample loading drive device 2 rises and falls along the Z direction to cooperate with the sample loaders 3.

[0054] For example, when adding samples, the second Z-axis driving module 15 drives the sample adding drive device 2 to descend along the Z direction, so that the sample adding drive device 2 descends to be connected to the sample adder 3, and transmits its driving force to the sample adding shaft of the sample adder 3, and the sample adding shaft of the sample adder 3 is pushed out from the sample outlet 301, so that the material can flow out of the sample adder 3 through the sample outlet 301; when the sample adding is stopped, the second Z-axis driving module 15 drives the sample adding drive device 2 to rise along the Z direction, so that the sample adding drive device 2 rises to be separated from the sample adder 3, thereby stopping its power transmission to the sample adding shaft of the sample adder 3, and the sample adding shaft of the sample adder 3 retracts to its end in the up and down directions to seal the sample outlet 301, so that the material stops flowing out.

[0055] In some preferred embodiments, the displacement drive module 1 further includes a first X-axis drive module 16 and a second X-axis drive module 17. The sampler 3 is connected to the bottom of the Z-axis drive module slider mounting plate 14 through the first X-axis drive module 16, and the sample loading drive device 2 is connected to the output end of the second Z-axis drive module 15 through the second X-axis drive module 17, so that the sample loading drive device 2 and the sampler 3 can cooperate to load samples at multiple positions along the X-direction, and load samples to multiple reaction bottles arranged along the X-direction, respectively, to improve the loading efficiency of a single operation.

[0056] Correspondingly, the reaction bottle guide 51 is provided with a plurality of positioning holes 511 arranged along the X direction, and the positioning holes 511 are coaxially arranged with the reaction bottle socket of the weighing module. The reaction bottle carrier 55 is provided with a plurality of reaction bottle sockets, and the plurality of reaction bottle sockets are arranged along the X direction, which are used to cooperate with the sampler 3 to add powder at multiple positions along the X direction, thereby improving the powder adding efficiency of a single operation.

[0057] In some preferred embodiments, the sample loading amount is controlled by the upper and lower connection cooperation of the sample loading drive device 2 and the sample loader 3 in the Z-axis direction, and the rotation of the driving end of the sample loading drive device 2 around its axis.

[0058] Specifically, Figure 4 This is a schematic diagram of the structure of the sample adding drive device in this application, such as Figure 4 As shown, the sample adding drive device 2 includes a driver 21, a bearing seat 22, and a drive shaft 23. The drive shaft 23 is connected to the driving end of the driver 21 through the bearing seat 22. Under the driving action of the driver 21, the drive shaft 23 drives the sample adding shaft of the sampler 3 to rotate and discharge the material.

[0059] In some preferred embodiments, the drive shaft 23 includes a pin 232, such as Figure 5 As shown, the pin shaft 232 is eccentrically arranged relative to the axis of the driving shaft 23, wherein the so-called eccentricity means that the driving pin is not located on the axis of the sample loading device, so that when the driver 21 rotates, the pin shaft 232 will drive the sample loading shaft of the sampler 3 to rotate around its axis.

[0060] In some preferred embodiments, the drive shaft 23 further includes an elastic member 231 , and the pin 232 is elastically connected to the lower portion of the drive shaft 23 through the elastic member 231 and extends downward, so that the pin 232 can be maintained in an extended position under the action of the elastic member 231 .

[0061] In some embodiments, the elastic member 231 may be a spring, which may be sleeved on the pin 232. In this way, the pin 232 can be kept in the extended position in a natural state, and the pin 232 can be prevented from retracting when power is transmitted to the sample loading shaft of the sample injector 3, thereby preventing the sample loading accuracy from being affected.

[0062] In some preferred embodiments, the number of the elastic members 231 and the pin shafts 232 is four, and the four pin shafts 232 are connected to the lower part of the driving shaft 23 in a cross distribution through the elastic members 231, so that when the driving shaft 23 transmits power to the sample loading shaft, the force on the sample loading shaft and the driving shaft can be evenly distributed, thereby extending the service life of the driving member.

[0063] Correspondingly, a holder that matches the pin 232 structure is also provided on the top of the sample injector 3 , so that the pin 232 can more efficiently transmit the rotational driving force to the sample injector shaft of the sample injector 3 .

[0064] Specifically, Figure 6 This is a schematic diagram of the structure of the sampler in this application, Figure 7 Schematic diagram of the side cross-section structure of the sample injector in this application, as shown in FIG. Figure 5 、 Figure 6 As shown, the sampler 3 includes a sample storage container 31, a sample loading shaft 32, a feeding box 33, and a holder 34. The sample loading shaft 32 is arranged in the sample storage container 31 along the axis of the sample outlet 301. The top of the sample loading shaft 32 is connected to the driving shaft 23 through the holder 34. Under the action of the driving force, the sample loading shaft 32 can rotate around its axis and can be displaced up and down along its axis to open or block the sample outlet 301.

[0065] In some preferred embodiments, the top of the card holder 34 is provided with four bosses 341, such as Figure 8 As shown, the bosses 341 are spaced apart around the axis of the holder 34, forming a gap between adjacent bosses 341. When the sample loading drive device 2 is lowered to engage with the sample loading device 3, the pin 232 can extend into the gap between two adjacent bosses 341, causing the sidewalls of the pin 232 to abut against the sidewalls of the bosses 341. The abutted pin 232 and bosses 341 can transmit power.

[0066] In some preferred embodiments, the sample loading shaft 32 includes a material discharging blade 321 and a sample loading groove 322. The material discharging blade 321 is located at the lower part of the sample loading shaft 32 and is used to stir and break up the material in the sample storage container 31 to improve the smoothness of the discharge. The sample loading groove 322 is located on the side of the lower part of the sample loading shaft 32 and is spirally arranged in a threaded shape along the axis of the sample loading shaft 32, so that when discharging, the material is slowly discharged through the threaded tooth-shaped sample loading groove 322, which is convenient for precise control of the discharge amount.

[0067] In some preferred embodiments, in order to further improve the accuracy of the powder feeding amount, the powder receiving trough assembly 4 is provided below the sampler 3, and the powder receiving trough assembly 4 is connected to the lower part of the displacement support seat 12, and is located below the sample outlet 301 and telescopically displaced along the Y direction to cooperate with receiving the excess material fed by the sampler 3. After the reading of the weighing device 5 reaches the required value, the powder receiving trough assembly is used to receive some powder selected in the air that has not yet fallen onto the weighing device 5. When the powder falls down, the weight of the powder on the weighing device 5 will exceed the preset situation.

[0068] Specifically, Figure 9 This is a schematic diagram of the structure of the powder receiving trough assembly 4 in this application, as shown Figure 9 As shown, the powder receiving trough assembly 4 includes a displacement driver 41, a driver mounting plate 42, a powder receiving trough 43, and a guide shaft 44. The displacement driver 41 is fixedly connected between the displacement support seat 12 and the driver mounting plate 42. The powder receiving trough 43 is connected to the output end of the displacement driver 41. Under the driving action of the displacement driver 41, the powder receiving trough 43 is reset and moved along the Y direction to cooperate with the sampler 3 to perform the powder receiving action.

[0069] In some preferred embodiments, the displacement driver 41 can be a through-type screw stepper motor, or a push rod motor or a cylinder, etc., as long as it can complete the action of pushing and retracting the powder receiving trough 43 along the Y direction, the specific form is not further limited here.

[0070] In some preferred embodiments, both ends of the powder receiving trough 43 are connected to the driver mounting plate 42 via the guide shaft 44, so as to prevent the powder receiving trough 43 from being offset in other directions during the displacement process, thereby increasing the stability of the displacement process.

[0071] The above is a detailed introduction to the specific implementation methods of the present application. For those skilled in the art, several improvements and modifications can be made to the present application without departing from the principles of the present application. These improvements and modifications also fall within the scope of protection of the claims of the present application.
