Description

Technical Field

[0001] The present invention belongs to the technical field of material detection, and in particular relates to a sampling inspection device and a use method thereof. Background Art

[0002] In modern industrial production, the quality control of powdered materials is one of the key links to ensure the quality of the final product. Powdered materials are usually transported to the destination by powder tankers, and then quality tested before entering the powder silo to ensure that they meet the relevant technical standards. However, the current powder testing method mainly relies on manual operation. This traditional method has many problems and challenges and needs to be improved urgently.

[0003] First, the existing sampling process has significant safety hazards. Sampling personnel usually need to climb onto the top of the powder tanker and open the manhole cover for visual inspection and sampling. This operation is carried out in an open-air environment. Especially in bad weather conditions (such as heavy rain, heavy snow, strong wind, etc.), sampling personnel are prone to slipping on slippery surfaces or falling from the ladder, leading to serious production safety accidents. In addition, the sampling process is exposed to the external environment, which may also cause the powder sample to be contaminated, affecting the accuracy of the test results.

[0004] Secondly, the lack of comprehensiveness and representativeness of sampling is a major problem of existing methods. Since the sampling point is limited to the manhole cover of the tank truck, the sampling area is relatively concentrated and cannot cover all the powder areas in the tank. This limitation means that the sample obtained may not represent the overall quality of the powder in the entire tank, especially when the powder is stratified or unevenly mixed during the loading process, which easily leads to the risk of inconsistent test results with the actual powder quality.

[0005] In addition, the low efficiency of powder unloading in the existing process has seriously affected the overall efficiency of logistics. In the traditional process, after the powder tanker arrives at the sampling site, it needs to go through a long sampling, sample delivery and inspection process, which usually takes nearly 3 hours. During this period, the powder tanker and the driver are in a static waiting state, resulting in low vehicle utilization, increased transportation costs and time costs. Moreover, since the entire inspection process takes a long time, it leads to increased transportation costs, which ultimately pushes up the market price of powder materials and affects the economic benefits of enterprises.

[0006] In addition, the traditional sampling, sample delivery, and inspection processes all rely on manual operations, which not only consumes a lot of human resources, but also poses management risks. The complexity of manual operations increases the possibility of errors, such as improper operations or inaccurate data records, which may affect the quality control of powders and the smooth progress of the production process. Summary of the invention

[0007] The purpose of the present invention is to solve the problem that the existing technology relies on manual operation, which increases the complexity of the process, is prone to human errors or irregular operations, and affects the accuracy and consistency of powder quality control.

[0019] Compared with the prior art, the present invention has the following beneficial effects: The sampling and inspection device integrates sampling, tableting, mold shifting and detection functions into one device, realizing automation and efficient collaboration of each process. The functional modules work closely together to ensure that the entire process from sample collection to detection is completed efficiently in a controlled environment. The flexibility of the device enables the tableting mold to move accurately between different positions to meet various work requirements. The overall design improves operational efficiency and consistency of sample processing, while ensuring the accuracy and reliability of test results, providing a comprehensive and reliable solution for sample inspection.

[0020] The mold shifting device can accurately move the tableting mold between different processes through linear motion or circular motion to meet various work requirements. This design improves the operational flexibility of the device and can adapt to complex operational requirements in different production environments. Since the mold shifting device can quickly and accurately position the tableting mold to the required position, it reduces waiting time and improves the overall operational efficiency.

[0021] The tablet pressing device applies uniform vertical pressure through the pressing drive to ensure that the powder sample is evenly pressed and formed, ensuring the consistency and quality stability of the sample.

DETAILED DESCRIPTION

[0042] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0043] refer to Figure 1-13 As shown, the present invention discloses a sampling and testing device on one hand, which includes a frame 1, a tablet pressing mold 2, a mold shifting device 3, a sampling device 4, a tablet pressing device 5, a detection device 6 and an electric control device 7; Specifically, the frame 1 is the basic structure of the sampling and testing device, supporting and installing components. The frame 1 is made of high-strength materials such as steel or aluminum alloy to ensure that it can withstand the mechanical stress applied during operation.

[0044] The tablet pressing mold 2 is a device used to tablet the sample during the inspection process, ensuring that the sample can be smoothly fed into the detection device for analysis.

[0045] The mold shifting device 3 is used to accurately position the tablet pressing mold.

[0046] The sampling device 4 is used to collect powder samples from the unloading conveying pipe of the powder tank truck.

[0047] The tablet pressing device 5 is used to tablet the collected sample to make it suitable for subsequent detection steps.

[0048] The detection device 6 is used to detect and analyze the sample after tableting to determine whether the sample meets the technical standards.

[0049] The electronic control device 7 is electrically connected to the above-mentioned mold shifting device 3, sampling device 4, tablet pressing device 5, detection device 6, demoulding device 9, core resetting device 12, sample sealing device 13 and marking device 14; and is used to control the operation process of the entire device, including the steps of sampling, tablet pressing, detection, demoulding, sample sealing and marking.

[0050] In the above embodiment, the mold shifting device 3, the tablet pressing device 5 and the detection device 6 are arranged on the frame 1 or the detection device 6 is installed outside the frame 1, and the sampling device 4 is connected to the unloading conveying pipe 8 of the powder tank truck.

[0051] The tableting mold 2 includes an outer mold 2.1 and a core 2.2. The core 2.2 is a cylindrical structure arranged inside the outer mold 2.1. The outer mold 2.1 is a sleeve-shaped structure with a through hole design that runs from top to bottom. The through hole is tightly matched with the core 2.2 to ensure that the core can remain stable during the tableting process; a core stopper 2.3 is provided at the lower part of the through hole. The function of the stopper 2.3 is to limit the core 2.2 to the lower position to prevent the core 2.2 from falling out of the lower part of the outer mold 2.1 due to gravity or other external forces. The stopper 2.3 not only ensures the safety and stability of the core during operation, but also effectively prevents the core from accidentally falling off, thereby increasing the operational reliability of the equipment; a stopper 2.4 is provided on the outer side of the upper end of the outer mold 2.1. The stop table 2.4 is used to precisely cooperate with the mold bracket 3.2 of the mold shifting device 3. Through this cooperation, the mold bracket 3.2 can provide stable support and precise positioning for the tablet pressing mold, thereby ensuring that the tablet pressing mold can maintain a stable posture during various operations (such as tablet pressing, shifting and demolding) and will not be displaced due to external forces, thereby improving the accuracy and consistency of the tablet pressing operation.

[0052] The mold shifting device 3 includes a driving mechanism 3.1 and a mold bracket 3.2. The driving mechanism 3.1 is fixed to the frame 1 and connected to the moving parts of the mold bracket 3.2. The tableting mold 2 is installed on the mold bracket 3.2. Through the mold shifting device 3, the tableting mold 2 can be smoothly moved between different operating positions to meet various operating requirements such as loading, tableting and testing.

[0053] The driving mechanism 3.1 is preferably a linear driving mechanism 3.1.1. The linear driving mechanism 3.1.1 includes a linear motion component, a guide assembly and a power assembly. The guide assembly is mounted on the frame 1, and the linear motion component is supported and mounted thereon by the guide assembly to ensure the stability and accuracy of its motion path. The power assembly is connected to the linear motion component, and by driving it to perform reciprocating linear motion along the track of the guide assembly, the linear displacement of the mold bracket 3.2 is achieved, thereby driving the tableting mold 2 to move precisely between different positions. The type of power assembly can be diverse, including motors, cylinders, hydraulic cylinders or electric cylinders, etc., and a suitable power source is selected according to specific application requirements to ensure the efficiency and reliability of the displacement process.

[0054] In addition, the drive mechanism 3.1 can also be in the form of a circular drive mechanism. The drive mechanism 3.1 realizes the position change of the tableting mold 2 through a circular motion component. The circular drive mechanism can move the mold bracket 3.2 along a circular path, thereby flexibly adjusting the working position of the tableting mold 2 to meet the requirements of different process steps. Whether it is a linear drive mechanism or a circular drive mechanism, the mold shifting device 3 can ensure the precise positioning and stable movement of the tableting mold 2 in various operation links such as loading, tableting, and testing, thereby improving the working efficiency and operation accuracy of the entire device.

[0055] The sampling device 4 includes a feeding barrel 4.1, a taking barrel 4.2, a taking piston 4.3 and a taking drive 4.4. The two ends of the feeding barrel 4.1 are respectively connected to the unloading conveying pipe 8 of the powder tank truck to ensure that the powder can be smoothly transported from the tank truck to the sampling device. The taking barrel 4.2 includes a segmented structure of a taking section 4.2.1 and a discharging section 4.2.2. The taking section 4.2.1 is located in the feeding barrel 4.1, and a taking port 4.2.11 is provided at the head of the taking section 4.2.1. The taking port 4.2.11 faces the direction of the incoming material, so that the powder can smoothly enter the taking port during the transportation process, ensuring the efficiency and quality of sample collection.

[0056] The discharge section 4.2.2 is provided with a discharge port 4.2.21, and a first valve 4.5 is provided below the discharge port 4.2.21. The first valve 4.5 is used to control the powder to flow out of the discharge port 4.2.21, and a sample storage cylinder 4.6 is connected below the first valve 4.5 to temporarily store the collected powder samples. A second valve 4.7 is also provided below the sample storage cylinder 4.6 to release or continue to process the stored samples at an appropriate time.

[0057] Since the feeding cylinder 4.1 generates a relatively high air pressure when feeding, during the sampling process, after the first valve 4.5 is opened and closed, the air pressure in the sample storage cylinder 4.6 will be balanced with the air pressure in the feeding cylinder 4.1, which is usually higher than the external atmospheric pressure. In order to prevent the sample in the storage cylinder from being damaged due to excessive pressure, a pressure relief valve 4.8 is provided on the sample storage cylinder 4.6. The function of the pressure relief valve 4.8 is to open when the air pressure in the sample storage cylinder 4.6 is too high, release the excessive pressure, and finally balance the air pressure in the storage cylinder with the external atmospheric pressure, thereby ensuring the safety and stability of the sample during the storage process.

[0058] The material taking piston 4.3 is arranged inside the material taking barrel 4.2 and driven by the material taking driving member 4.4. Under the action of the material taking driving member 4.4, the material taking piston 4.3 moves along the axial direction of the material taking barrel 4.2, and the powder material is smoothly transported from the material taking section 4.2.1 to the material discharging section 4.2.2, so that the sampling device can accurately control the collection and transportation process of the powder material sample to ensure the integrity and representativeness of the sample.

[0059] In order to further optimize the sampling process, a pressure sensor 4.9 is also provided on the feeding barrel 4.1. The pressure sensor 4.9 is used to detect the air pressure in the feeding barrel 4.1 in real time to determine the conveying state of the powder. This function enables the device to adjust the sampling and conveying operations in time according to the pressure changes in the feeding barrel 4.1, ensure the continuity and efficiency of the sampling process, and prevent sampling failure or inaccuracy caused by air pressure fluctuations.

[0060] The tablet pressing device 5 comprises a bottom plate 5.1, a top plate 5.2, a connecting member 5.3 and a pressing driving member 5.4.

[0061] The bottom plate 5.1 is fixed on the frame 1 to provide a stable support base for the entire tablet pressing device. The pressing drive 5.4 is installed on the bottom plate 5.1 and is responsible for providing the required vertical pressure for the tablet pressing process. The bottom plate 5.1 and the top plate 5.2 are arranged parallel to each other to form a parallel and stable structure to ensure uniform force transmission during the tablet pressing process. The bottom plate 5.1 and the top plate 5.2 are connected by a plurality of connectors 5.3, which not only play a fixing role, but also provide additional support for the stability of the top plate 5.2 to prevent structural deformation or displacement caused by uneven pressure during the powder material forming process.

[0062] An upper pressing head 5.5 is provided below the top plate 5.2, and the bottom surface of the upper pressing head 5.5 is arranged parallel to the bottom plate 5.1 to ensure that the pressure applied during tableting is evenly distributed on the tableting mold 2, thereby ensuring the consistency and reliability of the molding quality of the powdered material.

[0063] A pressing rod 5.6 is provided on the pressing driving member 5.4. The pressing rod 5.6 is arranged at the output end of the pressing driving member 5.4 so as to press the powder sample in the tablet pressing mold 2 under the drive of the pressing driving member 5.4.

[0064] The pressure rod 5.6 is also provided with a mold closing spring 5.7, which provides auxiliary pressure during the tableting process to ensure that when the pressing drive is running, pressure can be applied to the outer mold 2.1 smoothly and evenly, avoiding the tableting effect being affected by instantaneous pressure fluctuations.

[0065] In the above embodiment, the pressing drive member 5.4 can select different power sources according to specific application requirements, including electric cylinders, hydraulic cylinders, air cylinders, crank slider mechanisms or cam mechanisms, etc. The diversified power selection makes the tablet pressing device more adaptable, can meet the requirements of different tablet pressing strengths and speeds, and ensure that the best tablet pressing effect can be achieved under various process conditions.

[0066] In order to further improve the accuracy and controllability of the tableting process, a force sensor 5.8 is provided between the upper pressure head 5.5 and the top plate 5.2. The force sensor 5.8 can monitor the pressure applied to the tableting die in real time, ensuring that each step of the powder material forming process is within the optimal pressure range, thereby improving the accuracy and consistency of the powder material forming and effectively avoiding tableting defects caused by excessive or insufficient pressure.

[0067] The detection device 6 includes a standard sample 6.1 and a standard sample reset mechanism 6.2. When the detection device 6 is in a non-detection state or is being calibrated, the standard sample reset mechanism 6.2 moves the standard sample 6.1 to a predetermined detection position for calibration. The standard sample reset mechanism 6.2 can adopt a translational standard sample reset mechanism to send the standard sample 6.1 to the detection position by horizontal movement, or a flip reset mechanism to position the standard sample 6.1 within the detection area by flipping. The flexible standard sample reset design ensures the accuracy and efficiency of the calibration process and improves the overall reliability and ease of operation of the detection device.

[0068] The sampling and testing device also includes a demoulding device 9, which is used to safely and smoothly remove the tablet 10 from the tableting mold 2. The demoulding device 9 can ensure the mold stability and sample integrity after the tableting process, and ensure the smooth and efficient demoulding operation. The demoulding device 9 includes a mold limiting mechanism 9.1, a demoulding ejector rod 9.2 and a demoulding power member 9.3.

[0069] The mold limiting mechanism 9.1 plays the role of fixing and limiting the outer mold 2.1 of the tableting mold. During the demoulding process, the outer mold 2.1 is subjected to a certain external force. The role of the mold limiting mechanism 9.1 is to ensure that the outer mold 2.1 will not be displaced or loosened during the entire demoulding process, thereby maintaining the overall stability of the device and the consistency of operation, and further effectively preventing the outer mold 2.1 from any deviation or sliding during the demoulding process, ensuring the smooth progress of the demoulding operation.

[0070] The demoulding ejector pin 9.2 is a key executive component in the demoulding process, and directly acts on the tablet 10. One end of the demoulding ejector pin 9.2 is connected to the demoulding power member 9.3. Through the power provided by the demoulding power member 9.3, the demoulding ejector pin 9.2 can generate sufficient thrust to eject the tablet 10 from the tablet mold 2. The demoulding ejector pin 9.2 can ensure that the force transmission is uniform and stable during the process of pushing the tablet 10, thereby avoiding any damage to the surface or internal structure of the tablet 10.

[0071] The demoulding power member 9.3 provides a driving force source for the demoulding ejector 9.2, which can be hydraulic, pneumatic or electric. The appropriate power component is selected according to the specific application requirements. The demoulding power member 9.3 can accurately control the magnitude and speed of the thrust according to the properties of the tablet 10 and the characteristics of the mold. The demoulding power member 9.3 ensures the accuracy of the demoulding process and reduces the damage to the tablet caused by excessive or uneven force, thereby improving the integrity of sample processing.

[0072] The demoulding device 9 can ensure smooth and accurate demoulding during operation. Whether it is the stable support provided by the mold limit mechanism 9.1, the precise thrust transmission of the demoulding ejector 9.2, or the reliable drive of the demoulding power member 9.3, the coordinated work of these components can significantly reduce the potential damage to the tablet during the demoulding process, ensuring that the tablet 10 maintains the consistency of its shape and physical properties when it is ejected from the mold 2. This optimized design ultimately improves the processing efficiency and overall quality of the samples, ensuring that each sample can complete demoulding and subsequent operations in the best condition.

[0073] In addition, the sampling and inspection device also includes a scraper 11, which is used to remove excess powder from the tableting mold 2 after the powder filling is completed. The scraper 11 can be fixedly or movably arranged on the frame 1. When the scraper 11 is fixedly arranged, the mold shifting device 3 moves the tableting mold 2 through the scraper 11, so that the scraper 11 and the tableting mold 2 move relative to each other, thereby scraping off excess powder on the mold surface, ensuring the cleanliness of the mold surface, and preventing excess powder from affecting the subsequent tableting process. When the scraper 11 is movably arranged, the scraper 11 itself moves on the tableting mold 2 through an independent motion mechanism to scrape off excess powder. Through this design, the scraper 11 can adapt to different operating requirements and ensure the cleanliness of the mold surface, thereby improving the accuracy and consistency of the tableting process.

[0074] In order to ensure that the mold core 2.2 can be accurately reset after each operation, the device also includes a mold core reset device 12. The mold core reset device 12 includes a mold core reset driver 12.1 and a mold core pressure rod 12.2. The mold core reset driver 12.1 transmits power through the mold core pressure rod 12.2 to push the mold core 2.2 from the working position back to the initial position, ensuring that the mold core can return to the correct position after each tabletting operation and prepare for the next operation. In order to prevent the impact force during the reset process from damaging the mold core, an elastic member 12.3 is provided at the head of the mold core pressure rod 12.2. The elastic member 12.3 absorbs part of the impact force during the reset process, reduces the direct impact on the mold core, prolongs the service life of the mold core, and improves the operational safety and stability of the entire device.

[0075] In addition, the sampling and inspection device also includes a sample sealing device 13, which is located below the loading point of the tableting mold. The main function of the sample sealing device 13 is to receive the powder collected from the sampling process and package it. The sample sealing device 13 can automatically seal the collected powder sample in a dedicated container to prevent the sample from being contaminated or damaged by the external environment during transportation or storage, ensure the integrity and safety of the sample, and provide reliable guarantee for subsequent quality inspection and analysis.

[0076] Furthermore, the sampling and testing device also includes a marking device 14, which marks the powder sample for identification and archiving.

[0077] During use, the sampling and inspection device ensures that the entire process from sampling to final sealing and labeling can be completed efficiently and accurately.

[0078] The following steps are included: The first step: issuing a sampling instruction. The electronic control device 7 first issues a sampling instruction to start the sampling program of the device.

[0079] Step 2: Pressure detection and judgment: the pressure sensor 4.9 detects the pressure in the feeding barrel 4.1 in real time and transmits the detected pressure signal to the electronic control device 7. The electronic control device 7 determines whether the feeding barrel 4.1 is in the powder conveying state according to the pressure signal. If the device detects that the feeding barrel 4.1 is not in the powder conveying state, the subsequent operation is not triggered to avoid unnecessary actions.

[0080] Step 3: Sampling operation. After confirming that the feeding tube 4.1 is in the powder conveying state, the electronic control device 7 issues a sampling command. At this time, the sampling device 4 starts to work, the first valve 4.5 opens, and the material taking drive 4.4 drives the material taking piston 4.3 to move to the material taking section 4.2.1. The powder enters the material taking piston 4.3 through the feeding port at the head of the material taking section 4.2.1. Subsequently, the material taking drive 4.4 drives the material taking piston 4.3 to convey the powder to the discharge section 4.2.2. The powder enters the sample storage tube 4.6 from the discharge port 4.2.21 through the opened first valve 4.5. After completion, the first valve 4.5 is closed and the pressure relief valve 4.8 is opened to balance the pressure in the sample storage tube 4.6 with the external pressure. At this time, the sampling process is completed.

[0081] Step 4: Loading process, the electronic control device 7 issues a loading command, and the mold shifting device 3 moves the tablet pressing mold 2 to the loading position. At this time, the second valve 4.7 is opened, and the powder in the sample storage cylinder 4.6 is smoothly loaded into the tablet pressing mold 2, and then the second valve 4.7 is closed to complete the loading operation.

[0082] Step 5: scraping off the excess material. After the loading is completed, the electronic control device 7 issues a scraping command. The scraping member 11 moves relative to the tablet pressing mold 2 to scrape off the excess powder on the surface of the tablet pressing mold 2 to ensure that the mold surface is clean and avoid excess powder affecting the quality of subsequent tablet pressing operations.

[0083] Step 6: Tablet pressing operation. After the scraping is completed, the electronic control device 7 issues a tablet pressing command, and the mold shifting device 3 moves the tablet pressing mold 2 to the tablet pressing position. The tablet pressing device 5 is started, and the clamping drive 5.4 drives the pressure rod 5.6 and the mold closing spring 5.7 to operate. The mold closing spring 5.7 makes the outer mold 2.1 fit tightly with the bottom surface of the upper pressure head 5.5, and the pressure rod 5.6 applies pressure to press the powder inside the mold core 2.2. The force sensor 5.8 monitors the pressure in the tablet pressing process in real time. When the pressure reaches the set value, the clamping drive 5.4 drives the pressure rod 5.6 and the mold closing spring 5.7 to retract, completing the tablet pressing operation.

[0084] Step 7: Sample inspection. After the tableting operation is completed, the mold shifting device 3 moves the tableting mold 2 and the sample tablet 10 therein to the position of the detection device 6. The electronic control device 7 issues an inspection instruction, and the detection device 6 inspects the sample tablet 10 and transmits the inspection result to the electronic control device 7. After the inspection is completed, the detection device 6 exits the inspection state.

[0085] Step 8: Sample demoulding, the electronic control device 7 issues a demoulding command, and the mold shifting device 3 moves the tableting mold 2 to the demoulding position. The mold limiting mechanism 9.1 firmly limits the tableting mold 2, and the demoulding power part 9.3 drives the demoulding ejector 9.2 to eject the sample tablet 10 from the tableting mold 2, ensuring that the sample is smoothly separated from the mold.

[0086] Step 9: Sample sealing, the demoulding sample pressed sheet 10 or the residual material scraped off in the fifth step enters the feeding port of the sample sealing device 13. The electronic control device 7 issues a sample sealing instruction, and the sample sealing device 13 seals the sample to ensure that the sample is not contaminated and damaged during transportation and storage.

[0087] Step 10: Sample sealing and labeling: After the sample is sealed, the labeling device 14 labels the sealed sample. The labeling device 14 generates a label containing sample information for sample identification and archiving, ensuring the traceability and management of the sample in subsequent processes.

[0088] Step 11: Mold core reset, the electronic control device 7 issues a mold core reset command, and the mold shifting device 3 moves the tablet pressing mold 2 to the mold core reset position. The mold core reset driving member 12.1 drives the mold core pressing rod 12.2 to push the mold core 2.2 back to the initial position to prepare for the next tablet pressing operation.

[0089] Step 12: Reset the standard sample of the detection device. When the detection device 6 is in a non-detection state or is being calibrated, the electronic control device 7 issues a standard sample reset instruction, and the standard sample reset mechanism 6.2 moves the standard sample 6.1 to the detection position to ensure the accuracy of the next detection operation.

[0090] The above steps complete a working cycle of the device. The above steps can be performed in sequence or in parallel when there is no conflict, so as to improve efficiency.

[0091] Embodiment 2: The driving mechanism 3.1 is a circular driving mechanism 3.1.2, which includes a circular motion module. The mold bracket 3.2 is connected to the circular motion component in the circular motion module, and the circular motion module drives the mold bracket 3.2 to rotate.

[0092] The scraper 11 is movably arranged on the frame 1 , and the scraper 11 moves to scrape off the excess powder on the tablet pressing mold 2 .

[0093] The rest is the same as in Example 1.
