Description
Technical Field
[0001] This utility model relates to the field of powder sampling technology, and in particular to a spatial multi-point automated sampling device. Background Technology
[0002] In the daily production of the powder processing industry, ensuring the consistency of powder material quality within a batch is crucial, and its testing highly depends on the accurate acquisition of representative samples. Current mainstream sampling methods rely on manual operation: operators must use sampling probes to manually insert and collect samples point by point from different locations within large-capacity packaging (such as ton bags). This process has significant drawbacks: First, it is inefficient; manual point-by-point sampling is time-consuming and labor-intensive, affecting overall production efficiency. Second, it is prone to large operational deviations; the selection of sampling points, the depth and angle of insertion / removal, and the sample collection process are easily affected by human factors such as operator skill level and fatigue, leading to insufficient sample representativeness. Third, these deviations directly affect the accuracy and reliability of subsequent testing and analysis results, thus impacting the objectivity of batch quality judgment.
[0003] Therefore, it is necessary to provide a high-efficiency, accurate, and spatially multi-point automated sampling device that can simultaneously perform multi-point sampling in space. Utility Model Content

[0008] Preferably, a plurality of the sampling probe mechanisms are arranged at intervals on the sampling support.
[0009] Preferably, the sampling probe body is detachably mounted on the sampling bracket.
[0010] Preferably, the sampling opening and closing assembly includes an opening and closing movement drive module and a sealing structure. The opening and closing movement drive module is disposed on the sampling probe body, and the sealing structure is movably disposed on the sampling probe body. The output end of the opening and closing movement drive module is connected to the sealing structure. The opening and closing movement drive module drives the sealing structure to move, thereby opening or closing each of the sampling ports.
[0011] Preferably, the sampling probe body has an internal accommodating space for accommodating materials, each sampling port is connected to the accommodating space, the sealing structure is movably disposed in the accommodating space and divides the accommodating space into several cavities along the length direction of the sampling probe body, and the sampling ports are connected to the cavities one by one; the sealing structure is driven to move by the opening and closing moving drive module, so that the sealing structure blocks the sampling ports at the positions of each cavity.
[0012] Preferably, the sealing structure has a plurality of sealing portions along the length direction of the sampling probe body, the sealing portions dividing the accommodating space into a plurality of cavities; the sealing structure is driven to move by the opening and closing moving drive module, so that each of the sealing portions moves into or out of the cavity, thereby sealing the sampling port at the location of each cavity.
[0013] Preferably, the spatial multi-point automated sampling device further includes a negative pressure extraction system and a negative pressure sampling tube. Each cavity is connected to the negative pressure extraction system and the negative pressure sampling tube. The negative pressure extraction system is used to provide negative pressure to the negative pressure sampling tube so as to extract the material in each cavity through each negative pressure sampling tube.

[0015] Compared with existing technologies, this utility model's spatial multi-point automated sampling device incorporates a lifting mechanism and a swing arm mechanism. The lifting mechanism drives the swing arm mechanism to rise and fall, while the swing arm mechanism drives the sampling bracket to swing, thereby adjusting the spatial position of the sampling probe mechanism. This allows the sampling probe mechanism to be aligned with different areas of a large-capacity package requiring sampling. Furthermore, because multiple sampling ports are spaced along the length of the sampling probe body, the sampling probe body can achieve sampling at different depths when the lifting mechanism lowers the sampling probe mechanism. The sampling opening and closing component can synchronously control the opening and closing of these sampling ports to collect samples at appropriate times. Therefore, this utility model's spatial multi-point automated sampling device can simultaneously perform automated multi-point sampling in space, effectively improving sampling efficiency while avoiding deviations caused by manual operation, ensuring the accuracy and representativeness of the samples.

[0022] To explain in detail the technical content, structural features, objectives and effects of this utility model, the following description is provided in conjunction with the embodiments and accompanying drawings.
[0023] Please see Figures 1 to 4 The spatial multi-point automated sampling device 100 of this utility model includes a frame 1, a lifting mechanism 2, a swing arm mechanism 3, a sampling bracket 4, and a sampling probe mechanism 5. The lifting mechanism 2 is mounted on the frame 1; the swing arm mechanism 3 is mounted on the lifting mechanism 2, and the lifting mechanism 2 drives the swing arm mechanism 3 to move up and down; the sampling bracket 4 is connected to the swing arm mechanism 3, and the swing arm mechanism 3 drives the sampling bracket 4 to swing; the sampling probe mechanism 5 includes a sampling probe body 51 and a sampling opening and closing assembly 52. The sampling probe body 51 is mounted on the sampling bracket 4, and the sampling probe body 51 has a plurality of sampling ports 511 spaced apart along its length direction. The sampling opening and closing assembly 52 is connected to the sampling probe body 51, and the sampling opening and closing assembly 52 is used to synchronously open or close each sampling port 511. The lifting mechanism 2 can be an existing linear motion lifting module.
[0024] When using the spatial multi-point automated sampling device 100 of this invention for sampling, the lifting mechanism 2 can drive the swing arm mechanism 3 to rise and fall, and the swing arm mechanism 3 can drive the sampling bracket 4 to swing, thereby adjusting the spatial position of the sampling probe mechanism 5 so that it can be aligned with different areas of the large-capacity packaging that needs to be sampled. Multiple sampling ports 511 on the sampling probe body 51 are spaced apart along the length direction, enabling sampling at different depths. The sampling opening and closing component 52 can synchronously control the opening or closing of these sampling ports 511 to collect samples at appropriate times. Therefore, the spatial multi-point automated sampling device 100 of this invention can achieve automated spatial multi-point synchronous sampling, effectively improving sampling efficiency and exhibiting high sampling efficiency. At the same time, it avoids deviations caused by manual operation, ensuring the accuracy and representativeness of the sampling.
[0025] Please see Figure 1 and Figure 3In one embodiment, the swing arm mechanism 3 includes a first connecting arm 31, a rotary arm drive module 32, and a second connecting arm 33. One end of the first connecting arm 31 is connected to the lifting mechanism 2, and the rotary arm drive module 32 is disposed on the other end of the first connecting arm 31. The output end of the rotary arm drive module 32 is connected to one end of the second connecting arm 33, and the rotary arm drive module 32 is used to drive the second connecting arm 33 to rotate. The sampling bracket 4 is connected to the other end of the second connecting arm 33. By setting the first connecting arm 31, the rotary arm drive module 32, and the second connecting arm 33, the swing arm mechanism 3 provides a foundation for the connection between the first connecting arm 31 and the lifting mechanism 2. The rotary arm drive module 32 can drive the second connecting arm 33 to rotate, thereby driving the sampling bracket 4 and its sampling probe mechanism 5 to swing, so that the sampling probe mechanism 5 can adjust the sampling position in a wider range, further improving the flexibility and applicability of the device, and can adapt to the sampling needs of large-capacity packaging of different sizes and positions. However, the structure of the swing arm mechanism 3 is not limited to this. For example, the swing arm mechanism 3 can also use only the aforementioned rotary arm drive module 32 and the second connecting arm 33. By directly mounting the rotary arm drive module 32 on the lifting mechanism 2, the rotary arm drive module 32 directly drives the second connecting arm 33 to rotate, thereby causing the sampling bracket 4 and its sampling probe mechanism 5 to swing. The rotary arm drive module 32 can be an existing rotary motor, but is not limited to this.
[0026] Furthermore, the spatial multi-point automated sampling device 100 also includes a rotation drive module 6, which is mounted on the swing arm mechanism 3. The output end of the rotation drive module 6 is connected to the sampling bracket 4, and the rotation drive module 6 is used to drive the sampling bracket 4 to rotate. By setting the rotation drive module 6, the sampling bracket 4 can be driven to rotate, thereby driving the sampling probe mechanism 5 to rotate. This allows adjustment of the angle position when the sampling probe body 51 is inserted into the powder material, enabling sampling at a more suitable angle position, further improving the accuracy and representativeness of the sampling, and ensuring that powder samples at different angle positions can be obtained. In this embodiment, the rotation drive module 6 drives the sampling bracket 4 together with the sampling probe mechanism 5 to rotate and adjust its position in the horizontal direction, thereby adjusting the orientation of the sampling port 511 to meet the sampling requirements. However, this is not a limitation. For example, in other optional embodiments, the rotation drive module 6 drives the sampling bracket 4 together with the sampling probe mechanism 5 to rotate and adjust its angle position on a plane such as an inclined plane or a vertical plane. The rotation drive module 6 can use an existing rotary motor, but is not limited to it.
[0027] Preferably, several sampling probe mechanisms 5 are arranged at intervals on the sampling support 4. The interval arrangement of multiple sampling probe mechanisms 5 on the sampling support 4 allows the device to simultaneously sample multiple different locations on a large-capacity package, greatly improving sampling efficiency and enabling the simultaneous acquisition of samples from multiple different locations. This provides a more comprehensive reflection of the quality of the powder material and further ensures the objectivity of batch quality assessment. In this embodiment, the number of sampling probe mechanisms 5 is five, but this is not a limitation.
[0028] Furthermore, the sampling probe body 51 is detachably mounted on the sampling bracket 4. The detachable mounting method of the sampling probe body 51 facilitates operation when the sampling probe mechanism 5 or the sampling probe body 51 is damaged or needs to be replaced with a sampling probe mechanism 5 or the sampling probe body 51 of different specifications. This improves the maintenance convenience and versatility of the device, and allows for flexible replacement of the appropriate sampling probe mechanism 5 or the sampling probe body 51 according to different powder material characteristics and sampling requirements.
[0029] Please see Figures 1 to 6 In one embodiment, the sampling opening and closing assembly 52 includes an opening and closing movement drive module 521 and a blocking structure 522. The opening and closing movement drive module 521 is disposed on the sampling probe body 51, and the blocking structure 522 is movably disposed on the sampling probe body 51. The output end of the opening and closing movement drive module 521 is connected to the blocking structure 522. The opening and closing movement drive module 521 drives the blocking structure 522 to move, thereby opening or closing each sampling port 511. The sampling opening and closing assembly 52 controls the opening or closing of each sampling port 511 by driving the blocking structure 522 to move through the opening and closing movement drive module 521. The structure is simple and the control is precise. When sampling is required, the opening and closing moving drive module 521 drives the sealing structure 522 to move and open the sampling port 511, allowing the powder material to enter. After sampling is completed, the driving sealing structure 522 moves to close the sampling port 511, preventing the sample from falling or becoming contaminated, thus ensuring the integrity and purity of the sample. The opening and closing moving drive module 521 can be an existing lifting cylinder, but is not limited to it. Specifically, to ensure the stability of the installation of the opening and closing moving drive module 521, it can also be further installed and positioned on the sampling bracket 4, but is not limited to it.
[0030] Furthermore, the sampling probe body 51 has an internal accommodating space 512 for containing materials. Each sampling port 511 is connected to the accommodating space 512. The sealing structure 522 is movably disposed within the accommodating space 512 and divides the accommodating space 512 into several cavities 512a along the length of the sampling probe body 51. Each sampling port 511 is connected to a corresponding cavity 512a. The sealing structure 522 is moved by the opening and closing movement drive module 521, so that the sealing structure 522 seals the sampling port 511 at the position of each cavity 512a. The accommodating space 512 of the sampling probe body 51 provides a place for temporary storage of materials. The sealing structure 522 divides the accommodating space 512 into multiple cavities 512a, and each cavity 512a is connected to the corresponding sampling port 511, so that samples collected from different sampling ports 511 can be stored in different cavities 512a, avoiding mixing between samples. The opening and closing moving drive module 521 drives the sealing structure 522 to move within the accommodating space 512, thereby blocking or opening the sampling port 511 corresponding to each cavity 512a. This allows for precise control of the sampling timing and sample quantity of each sampling port 511, further improving the accuracy of sampling.
[0031] Specifically, the sealing structure 522 has several sealing portions 522a along the length of the sampling probe body 51, which divide the accommodating space 512 into several cavities 512a. The sealing structure 522 is moved by the opening and closing movement drive module 521, causing each sealing portion 522a to move into or out of the cavity 512a, thereby sealing the sampling port 511 at the location of each cavity 512a. For example, the sealing structure 522 may have several sealing portions 522a arranged at intervals on a rod (not shown in the figure), with the opening and closing movement drive module 521 connected to the rod to drive the sealing structure 522 to move, but this is not a limitation. The sealing portions 522a on the sealing structure 522 not only serve to divide the accommodating space 512 into cavities 512a, but can also seal the sampling port 511 by moving into or out of the cavity 512a. When the sealing part 522a enters the cavity 512a, it can effectively seal the corresponding sampling port 511 to prevent material from entering; when the sealing part 522a leaves the cavity 512a, the sampling port 511 opens and the material enters the cavity 512a.
[0032] In one embodiment, after the material enters the cavity 512a, the sealing part 522a of the sealing structure 522 can be driven to move into the cavity 512a by the opening and closing moving drive module 521, so that the sealing part 522a re-seals the sampling port 511. During this process, the sealing part 522a can push the material in the cavity 512a to move, but is not limited thereto.
[0033] Please see Figure 1 , Figure 3 and Figure 5 In one embodiment, the spatial multi-point automated sampling device 100 of this utility model further includes a negative pressure extraction system 7 and a negative pressure sampling tube 8. Each cavity 512a is connected to the negative pressure extraction system 7 with a negative pressure sampling tube 8. The negative pressure extraction system 7 provides negative pressure to the negative pressure sampling tube 8 to extract the material from each cavity 512a through the negative pressure sampling tube 8. By setting up the negative pressure extraction system 7 and the negative pressure sampling tube 8, the sample in the cavity 512a can be smoothly extracted by the negative pressure, avoiding the occurrence of residue or contamination of the sample during the extraction process. At the same time, each cavity 512a corresponds to an independent negative pressure sampling tube 8, which can ensure that the samples from different cavities 512a do not mix with each other, ensuring the independence and accuracy of the samples and providing a reliable sample basis for subsequent detection and analysis.
[0034] Furthermore, the spatial multi-point automated sampling device 100 of this utility model also includes a sample collection module 9, which is mounted on the frame 1. The sample collection module 9 has several metering and packaging sections 91, and each negative pressure sampling tube 8 is connected to one of the metering and packaging sections 91. The metering and packaging sections 91 are used to meter and package the materials. A negative pressure is provided to the negative pressure sampling tubes 8 by the negative pressure sampling system 7, so that the materials in each cavity 512a are drawn into each metering and packaging section 91 through each negative pressure sampling tube 8. By setting up the sample collection module 9, automatic metering and packaging of samples are realized. Each negative pressure sampling tube 8 draws samples from different cavities 512a into the metering and packaging sections 91, which can accurately meter and package the samples, facilitating subsequent labeling, testing, and storage. This process is fully automated, avoiding errors and contamination that may be caused by manual operation, further improving the efficiency and reliability of the entire sampling process, and enabling samples to quickly and accurately enter the testing stage.
[0035] Combination Figures 1 to 6 The specific working principle of the spatial multi-point automated sampling device 100 of this utility model is as follows:
[0036] The material to be sampled is transported to the operating range of the automated sampling platform. The lifting mechanism 2 is activated, driving the swing arm mechanism 3 to rise and adjust to a suitable height so that the sampling probe mechanism 5 can be aligned with the sampling area of large-capacity packaging (such as ton bags). The rotary arm drive module 32 in the swing arm mechanism 3 operates, driving the second connecting arm 33 to rotate, thereby causing the sampling bracket 4 and the sampling probe mechanism 5 to swing and reach the required lateral position for sampling. If the sampling angle needs to be adjusted, the rotation drive module 6 will drive the sampling bracket 4 to rotate, thereby driving the sampling probe mechanism 5 to adjust to a suitable insertion angle. The opening and closing movement drive module 521 drives the sealing structure 522 to move, causing the sealing part 522a on the sealing structure 522 to descend and enter the corresponding cavity 512a, thereby sealing and closing each sampling port 511.
[0037] Next, the lifting mechanism 2 is activated, driving the swing arm mechanism 3, along with the sampling bracket 4 and the sampling probe mechanism 5, to descend. Once the sampling probe mechanism 5 is inserted into the material and reaches the designated sampling position, the sampling opening and closing assembly 52 begins operation. The opening and closing movement drive module 521 drives the sealing structure 522 to move, causing the sealing part 522a on the sealing structure 522 to leave the corresponding cavity 512a. At this time, each sampling port 511 opens. Because the sampling ports 511 on the sampling probe body 51 are spaced apart along the length direction and are connected to different cavities 512a, the powder material will enter the corresponding cavity 512a through each sampling port 511, achieving multi-point sampling at different depths and positions.
[0038] After sampling is completed, the opening and closing moving drive module 521 drives the sealing structure 522 to move, causing the sealing part 522a to enter each cavity 512a, sealing the corresponding sampling port 511 and preventing the sample from falling or mixing. Subsequently, the negative pressure extraction system 7 is activated, applying negative pressure to the corresponding cavity 512a through each negative pressure sampling tube 8, extracting the sample from the cavity 512a. The sample is then transported through the negative pressure sampling tube 8 to the metering and packaging section 91 of the sample collection module 9. The metering and packaging section 91 accurately measures the sample and then packages it, completing the entire sampling process.
[0039] Throughout the sampling process, multiple sampling probes 5 can operate simultaneously to sample from different locations, significantly improving sampling efficiency. Furthermore, the automated control of the entire process avoids various deviations caused by manual operation, ensuring sampling accuracy and sample representativeness, and providing a reliable basis for subsequent testing, analysis, and batch quality assessment.
[0040] In addition, the sampling probe body 51 adopts a detachable installation method. When it is necessary to replace the sampling probe mechanism 5 or the sampling probe body 51, simply remove the old sampling probe mechanism 5 or the sampling probe body 51 from the sampling bracket 4 and install the new sampling probe mechanism 5 or the sampling probe body 51. The operation is simple and convenient, which improves the maintenance efficiency and versatility of the device.
[0041] In summary, the automated multi-point sampling device 100 of this invention can simultaneously perform multi-point sampling in space, and the entire sampling process is automated, greatly saving sampling time and improving production efficiency. Secondly, the automated multi-point sampling device 100 of this invention precisely controls the sampling position, angle, and depth through a mechanical structure, avoiding deviations caused by manual operation and ensuring the accuracy and representativeness of the sampling, making subsequent testing and analysis results more accurate and reliable. Furthermore, the automated multi-point sampling device 100 of this invention, through the cooperation of the swing arm mechanism 3, the lifting mechanism 2, and the rotation drive module 6, allows the sampling probe mechanism 5 to adjust its position and angle within a wide range to adapt to different sampling needs. Finally, the automated multi-point sampling device 100 of this invention, through the coordinated work of the sampling opening and closing component 52, the negative pressure extraction system 7, and the sample collection module 9, ensures the integrity, independence, and purity of the samples, providing a reliable sample basis for batch quality judgment.
[0042] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Therefore, any equivalent variations made in accordance with the scope of the present utility model application shall still fall within the scope of the present utility model.
