Description

Technical Field

[0001] This application relates to the field of powder sampling technology, specifically to powder sampling devices. Background Technology

[0002] In the production, storage, and transportation of powder materials (such as lithium battery active material powders), the uniformity and representativeness of samples are crucial for quality control. Therefore, accurate sampling techniques are a vital step in ensuring powder quality. Currently, powder sampling mainly includes manual sampling and mechanical sampling. Manual sampling is performed by operators based on experience and prescribed procedures. The advantage of this method is its flexibility, allowing for adjustments to specific situations. However, due to differences in operator skills and work attitudes, the results of manual sampling are often difficult to standardize. Mechanical sampling, on the other hand, often results in incomplete or ineffective sampling. Utility Model Content

[0005] This application utilizes a powder sampling device installed on the production pipeline. A drive unit propels a sampling component along a first pipeline towards the production pipeline, collecting powder at the sampling location. The drive unit then propels the sampling component away from the production pipeline, delivering the powder to a second pipeline at the discharge location, from which it is then transported to the sample collection area. Because the first pipeline is directly connected to the production pipeline, the problems of incomplete and ineffective sampling are solved, allowing for rapid sample acquisition at the sampling location and ensuring the timeliness and representativeness of the samples. The second pipeline, corresponding to the discharge location, effectively transports the powder to the sample collection area, avoiding sample scattering and dust contamination issues that may occur during manual sampling, thus improving sampling accuracy and safety. Through the cooperation of the drive unit, the entire sampling process is automated, optimizing the continuity and reliability of sampling, reducing sampling errors caused by human factors, and allowing sampling to be performed without interrupting the production process, significantly reducing the risk of operational interruptions.

The first connecting section connects the first material-receiving section and the second material-receiving section, and the second connecting section is connected to the driving component. A material-receiving space is formed between the first material-receiving section and the second material-receiving section. The driving component is used to drive the material-receiving component to move in the direction of the material-receiving position so that the material-receiving space is filled with the powder. The driving component is also used to drive the material-receiving component to move in the direction of the material-discharging position so as to transport the powder in the material-receiving space to the second pipe.

[0007] In some embodiments of this application, the outer diameters of the first and second material-taking parts are the same as the inner diameter of the first pipe.

[0008] In some embodiments of this application, the first connecting part is movably connected to the second picking part to adjust the distance between the first picking part and the second picking part.

[0009] In some embodiments of this application, the first pipeline is connected to the production pipeline via a first flange, and the drive component is connected to the first pipeline via a second flange.

[0010] In some embodiments of this application, a baffle plate is further provided at the connection between the drive component and the first pipe, and the baffle plate is located inside the second flange.

[0011] In some embodiments of this application, the first pipe and the second pipe are arranged perpendicular to each other.

[0012] In some embodiments of this application, the second pipeline includes a third connecting part and a conveying pipe. The third connecting part and the conveying pipe are connected by a third flange. The third connecting part is disposed opposite to the discharge position and communicates with the first pipeline. The diameter of the end of the third connecting part connected to the first pipeline is smaller than the diameter of the end of the third connecting part connected to the conveying pipe.

[0013] In some embodiments of this application, a clamp is also provided at one end of the second conduit near the sample collection area.

[0043] Please see Figure 1 and Figure 2 This application provides a powder sampling device 10 for sampling powder within a production pipeline 100. The powder sampling device 10 includes a first pipeline 200, a second pipeline 300, a sampling component 400, and a driving component 500. The first pipeline 200 includes a sampling position 201 and a discharging position 202. The sampling position 201 is connected to the production pipeline 100 to receive powder within the production pipeline 100. The second pipeline 300 is connected to both the discharging position 202 and a sample collection area 11. The sampling component 400 is arranged along the length of the first pipeline 200 and is used to collect powder from the sampling position 201. The driving component 500 is connected to the end of the first pipeline 200 furthest from the production pipeline 100. The material taking component 400 is fixed on the driving component 500. The driving component 500 is used to drive the material taking component 400 to reciprocate between the material taking position 201 and the material discharging position 202, so as to transport the powder obtained by the material taking component 400 to the sample collection area 11 through the material discharging position 202 and the second pipe 300.

[0044] This application provides a powder sampling device 10 installed on the production pipeline 100. A drive unit 500 can drive a sampling component 400 to move along the first pipeline 200 towards the production pipeline 100, collecting powder at sampling position 201. The drive unit 500 then drives the sampling component 400 to move away from the production pipeline 100, conveying the powder to the second pipeline 300 at the discharge position 202, and from there to the sample collection area 11. Since the first pipeline 200 is directly connected to the production pipeline 100, the required sample can be quickly obtained at sampling position 201, ensuring timely and representative sampling. The second pipeline 300 corresponds to the discharge position 202, effectively conveying the powder to the sample collection area 11, avoiding sample scattering and dust pollution problems that may occur during manual sampling, thus improving the accuracy and safety of sampling. With the assistance of the drive unit 500, the entire sampling process is automated, optimizing the continuity and reliability of sampling, reducing sampling errors caused by human factors, and allowing sampling to be carried out without interruption of the production process, greatly reducing the risk of operation interruption.

[0045] This application provides a powder sampling device 10 installed on the production pipeline 100. A driving component 500 drives a sampling component 400 to move along the first pipeline 200 towards the production pipeline 100, collecting powder at sampling position 201. The driving component 500 then drives the sampling component 400 to move away from the production pipeline 100, conveying the powder to the second pipeline 300 at the discharge position 202, and from there to the sample collection area 11. Since the first pipeline 200 is directly connected to the production pipeline 100, the problem of incomplete or ineffective sampling is solved, allowing for rapid acquisition of the required sample at sampling position 201, ensuring the timeliness and representativeness of the sample. The second pipeline 300, corresponding to the discharge position 202, effectively conveys the powder to the sample collection area 11, avoiding sample scattering and dust pollution problems that may occur during manual sampling, thus improving the accuracy and safety of the sampling. With the assistance of the drive unit 500, the entire sampling process is automated, optimizing the continuity and reliability of sampling, reducing sampling errors caused by human factors, and allowing sampling to be carried out without interruption of the production process, greatly reducing the risk of operation interruption.

[0046] like Figure 2As shown, in one embodiment of this application, the material-receiving component 400 includes a first material-receiving section 401, a first connecting section 403, a second material-receiving section 402, and a second connecting section 404 arranged sequentially in a direction away from the material-discharging position 202. The first connecting section 403 connects the first material-receiving section 401 and the second material-receiving section 402, and the second connecting section 404 is connected to the driving component 500. A material-receiving space is formed between the first material-receiving section 401 and the second material-receiving section 402. The driving component 500 is used to drive the material-receiving component 400 to move in the direction of the material-receiving position 201 so that the material-receiving space is filled with powder. The driving component 500 is also used to drive the material-receiving component 400 to move in the direction of the material-discharging position 202 so as to transport the powder in the material-receiving space to the second pipe 300. This material-receiving space provides sufficient volume for sample storage, ensuring that enough powder is successfully collected. The drive unit 500 can drive the picking unit 400 to move towards the picking position 201, so that the powder discharged from the production pipe 100 fills the picking space. The drive unit 500 also drives the picking unit 400 to move towards the discharging position 202, so that the powder in the picking space is transported to the second pipe 300. This design effectively reduces mechanical interference during sampling and ensures the stability of the sample during transfer, reducing the possibility of sample scattering and loss. The structure of the picking unit 400 allows for rapid switching between sampling and discharging processes, greatly improving sampling efficiency and meeting the requirements of modern production for rapid response and high-quality control. Optionally, the drive unit 500 can be a cylinder.

[0047] In one embodiment of this application, the outer diameters of the first picking section 401 and the second picking section 402 are the same as the inner diameter of the first pipe 200. By ensuring that the outer diameter of the picking section is completely consistent with the inner diameter of the first pipe 200, seamless connection can be achieved, avoiding leakage and retention of powder during the transfer process. This tightness reduces the frictional resistance of the material during flow, thereby improving the flowability and efficiency of sampling. It enhances the overall stability and sealing of the system, effectively preventing dust contamination and sample scattering, ensuring cleanliness and safety during the sampling process. It simplifies the installation and maintenance process of the device, reducing the risk of failure due to misalignment or poor connection.

[0048] In one embodiment of this application, the first connecting part 403 is movably connected to the second picking part 402 to adjust the distance between the first picking part 401 and the second picking part 402. This adjustable connection method allows for flexible setting of the picking space size according to different production conditions and sampling requirements, thereby adapting to various types and particle sizes of powders. This ensures that sampling can cover a sufficient sample volume when processing different powders, improving the representativeness and accuracy of the samples. The movable connection design reduces sampling difficulties caused by the characteristics of the powder itself. By adjusting the distance between the picking parts, clogging of powder during the picking process can be effectively avoided, thereby achieving smoother powder flow and collection. At the same time, this setting also reduces the wear of the equipment itself and extends its service life. The movable connection also allows for fine-tuning of the picking part during the sampling process to cope with changes that may occur during production. Optionally, the first connecting part 403 and the second picking part 402 are threaded together.

[0049] In one embodiment of this application, the first pipe 200 is connected to the production pipe 100 via a first flange 601, and the drive component 500 is connected to the first pipe 200 via a second flange 602.

[0050] In one embodiment of this application, a baffle plate 604 is further provided at the connection between the drive component 500 and the first pipe 200, and the baffle plate 604 is located inside the second flange 602. The baffle plate 604 can effectively prevent the powder from flowing backward or leaking during the conveying process, ensuring that the powder remains stable when flowing in the pipe. The baffle plate 604 can also play a role in cleaning and guiding to some extent. When the powder flows to the connection, the baffle plate 604 can help concentrate the powder flow and reduce the possibility of stagnation and blockage. This will help improve the powder conveying efficiency and ensure the accuracy and efficiency of the sampling process. The presence of the baffle plate 604 also helps protect the drive component 500. By preventing the powder from directly contacting the drive component 500, the risk of wear on the mechanical parts by the powder can be reduced, and the service life of the equipment can be extended.

[0051] In one embodiment of this application, the first pipe 200 and the second pipe 300 are arranged perpendicularly to each other. This vertical pipe structure facilitates smooth flow of powder within the pipes. When powder flows from the first pipe 200 to the second pipe 300, the vertical connection reduces friction and resistance during powder transfer, ensuring rapid powder transport. The vertical configuration of the first and second pipes 300 also facilitates inspection and maintenance.

[0052] In one embodiment of this application, the second pipe 300 includes a third connecting part 301 and a conveying pipe 302. The third connecting part 301 and the conveying pipe 302 are connected by a third flange 603. The third connecting part 301 is disposed opposite to the discharge position 202 and communicates with the first pipe 200. The diameter of the end of the third connecting part 301 connected to the first pipe 200 is smaller than the diameter of the end of the third connecting part 301 connected to the conveying pipe 302. This smaller diameter at the end connected to the first pipe 200 not only effectively guides and concentrates the powder flowing into the conveying pipe 302, reducing the risk of powder scattering during transfer, but also utilizes gravity to accelerate the flow of the powder, ensuring that the powder can quickly and smoothly fill the conveying pipe 302. This design optimizes the flowability of the powder and improves the overall system efficiency.

[0053] In one embodiment of this application, a clamp 800 is also provided at the end of the second conduit 300 near the sample collection area 11. The clamp 800 makes the sample collection process simpler and more efficient. The clamp 800 can quickly and securely fix the sampling bag, ensuring that the bag will not be accidentally moved or detached during sampling. Optionally, the clamp 800 can be an airbag clamp. When the sampling bag is placed on the clamp 800, the airbag clamp 800 can inflate to clamp the sampling bag.

[0054] In one embodiment of this application, a weighing module 900 is provided in the sample collection area 11 at the lower end of the second pipe 300 for weighing the obtained powder. The weighing module 900 can monitor the weight of the sample in real time to ensure that the quantity of each sample taken meets the expectation.

[0055] The working principle of this application is as follows: The operator places the sampling bag on the sampling bag holder 800, and sets the weight of a single powder package, the number of sampling packages in a single batch, the dwell time of the drive component 500 at the sampling position, and the dwell time of the drive component 500 at the dispensing position 202 through the controller. The powder sampling device 10 is then started. At this time, the drive component 500 drives the picking component 400 to move towards the sampling position, where it stays for the set dwell time, and the sample falls into the sampling space. After the dwell time ends, the drive component 500 drives the picking component 400 to move towards the dispensing position 202, and the sample falls into the sampling bag through the second pipe 300, and sampling is repeated. The weighing module 900 displays the weight of the powder in the sampling bag in real time. If the sample in the sampling bag reaches the set weight of a single powder package multiplied by the number of sampling packages in a single batch, the drive component 500 drives the picking component 400 to stop at the dispensing position 202, ending the sampling process.

[0056] The controller records the production time of the powder and the corresponding sampling time for each batch. If the sampling time exceeds 80% of the production time, it indicates that the obtained sample does not meet the sampling coverage requirement and is therefore unacceptable. The controller is then used to change the dwell time at the material discharge position 202 to dwell time / 80%, and subsequent operations are performed based on the changed parameters to ensure that the sampling coverage is met.

[0057] If the production line for producing powder gives an end signal and the weight of the powder on the weighing module 900 does not reach the set weight of a single bag of powder multiplied by the actual number of sample bags, the controller will give a stop signal. The cycle will stop after the current drive component 500 drives the picking component 400 to move toward the discharging position 202.

[0058] The controller will signal to halve the dwell time of the currently configured drive unit 500 at the feeding position 202, and will then perform subsequent operations according to the modified parameters. This parameter change aims to ensure that subsequent sample weights meet the standard. If the weight of the last package does not meet the requirements, the controller will send an audible and visual alarm signal to the touchscreen display, requiring manual reset and manual replenishment of the sample weight. If three consecutive single-package weights fail to meet the requirements, the controller will send an audible and visual alarm signal to the touchscreen display, requiring manual reset and a check of whether sampling was effective.

[0059] The above embodiments are only used to illustrate the technical solutions of this application and are not intended to limit it. Although this application has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this application without departing from the spirit and substance of the technical solutions of this application.
