Description

Technical Field

[0001] This utility model relates to the field of production testing, and more specifically, to a particle detection component for use on a continuous production line. Background Technology

[0002] Hard granules on the production line, such as phosphate granules, often contain larger, non-compliant particles mixed in with the qualified smaller particles. Oversized particles can negatively impact the final product's appearance, performance, and even damage subsequent processing equipment. Therefore, effectively monitoring the particle size distribution of materials during production, processing, and transportation is crucial for ensuring product quality and process stability.

[0003] Current testing methods primarily rely on manual sampling. Workers manually collect a portion of the fertilizer, count it, and calculate the percentage of large particles to determine the fertilizer's pass rate. While simple and easy to implement, this method has several inherent drawbacks. Regarding testing effectiveness, manual sieving and weighing are time-consuming and labor-intensive, making it difficult to meet the real-time monitoring needs of continuous production processes. It also fails to promptly detect and correct anomalies, resulting in low testing efficiency. Regarding accuracy, manual visual inspection and sieving results are easily influenced by the operator's subjective judgment and skill level, leading to deviations, a lack of objectivity and consistency, and significant human error. For workers, prolonged repetitive sampling and sieving work increases their workload significantly. Utility Model Content

[0004] The present invention aims to overcome at least one of the defects (deficiencies) of the prior art and provide a particle detection component for continuous production lines, making detection more convenient.

[0005] The technical solution adopted by this utility model is to provide a particle detection component for a continuous production line, comprising:

[0006] Erect supports for use on the transmission path of the production line;

[0007] The support frame is equipped with a movable sampling arm, which is used to take samples along the transmission path;

[0008] The support frame is also equipped with a testing platform, which includes a material guiding channel;

[0009] The material guide channel is equipped with a detection component, a feeding port, and a return port that connects to the transmission path.

[0010] In this technical solution, the testing station is directly installed on the production line using a support frame, enabling real-time online sampling and material return to the production line. This eliminates the need for manual sampling and return, significantly improving convenience. The sampling arm is used to sample particles from the production line; the feed port is the entry point for particle samples into the testing station; and the return port is the exit point for tested particle samples, connected to the transmission path so that tested particles can flow back to the production line. This ensures that even frequent testing does not affect production output, allowing for multiple tests to improve the pass rate of produced particles. The testing station is used to test the particles on the production line to obtain the required data. This solution, through the coordinated arrangement of the support frame, sampling arm, testing station, feed port, testing components, and return port, automates sampling, testing, and material return, making testing more convenient, greatly improving testing efficiency, and saving manpower and testing time.

[0011] Furthermore, the support frame includes a support rod and a horizontal frame, the horizontal frame is provided with a horizontal moving mechanism, and the horizontal moving mechanism is provided with a lifting seat; the sampling arm is disposed on the lifting seat.

[0012] In this technical solution, the horizontal frame is connected to the top of the support rod, which supports the horizontal frame above the conveyor path of the production line. A horizontal moving mechanism moves the lifting seat horizontally, thereby moving the sampling arm on the lifting seat horizontally. The lifting seat moves the sampling arm longitudinally. This makes the movement of the sampling arm more flexible, adaptable to more production lines of different specifications, meeting more diverse sampling needs, and improving applicability. For user manufacturers, this increases the utilization rate of the detection components in this solution. Furthermore, the entire sampling process does not require manual adjustment of the sampling arm's position, simplifying the sampling operation.

[0013] Furthermore, the sampling arm includes: a shielding plate and a sampling box; the shielding plate is connected to the lifting base and forms at least a shielding direction in the transmission direction and towards the detection table; the sampling box is rotatably mounted on the shielding plate; the material storage height of the sampling box is at least not less than the material thickness on the transmission path; a gap is left between the sampling box and the shielding plate.

[0014] In this technical solution, the shielding plate forms a barrier in the transmission direction. When sampling is to be performed at a specific location, the sample particles around it will not enter the sampling box due to the shielding plate. The shielding plate also forms a barrier on one side of the detection platform, which can prevent the sample flowing out of the return port from re-entering the sampling box. This improves the accuracy of sampling and the reliability of the test results. At the same time, since no manual shielding is required, the convenience of the sampling operation is also improved.

[0015] The material storage height of the sampling box is at least as high as the material thickness along the transmission path. This means that the sampling box can collect particles from the top to the bottom of the sampling section on the production line. Since large particles are usually located at the top and small particles at the bottom on the production line, this design allows for uniform sampling of both large and small particles, thereby improving the representativeness of the sample.

[0016] A gap is left between the sampling box and the shielding plate. The gap provides sufficient rotation space for the sampling box and avoids the shielding plate affecting the rotation of the sampling box.

[0017] Furthermore, the testing platform includes: a material receiving section, a testing section, and a return section connected sequentially from high to low; the feeding port is located on the side of the material receiving section away from the transmission path; the return port is located on the side of the return section close to the transmission path; the testing component includes: a weighing device, which is installed on the material receiving section.

[0018] In this technical solution, the receiving section is a structure used to receive the sample to be tested. The sample enters from the receiving section, flows into the testing section for testing, and then passes through the return section before being recycled back to the production line. The weighing device is used to weigh the sample on the receiving section to obtain weight data.

[0019] Furthermore, the material receiving section includes a material storage bin with an inclined surface inside; the material storage bin has a discharge port on the side near the detection section, the discharge port has an opening and closing door, and the feeding port is located at the top of the material storage bin; the weighing device is located below the material storage bin and is used to measure the weight change of the material storage bin.

[0020] In this technical solution, the sample particles to be tested enter the silo through the feeding port, and the weighing device obtains the weight data of the sample by measuring the weight change in the silo. The opening and closing door is used to block the sample to be tested inside the silo. When the opening and closing door is opened, since the ground inside the silo is inclined, the sample to be tested flows out of the receiving section under the action of gravity and enters the testing section.

[0021] Furthermore, the opening and closing gate is rotatably mounted on the discharge port; when the opening and closing gate is opened, it forms a scraper so that the material passing through the discharge port is flattened; the feeding port is provided with a screening mechanism, and the screening mechanism is provided with multiple filter holes; the filter holes are used to retain excessively large particles in the screening mechanism.

[0022] In this technical solution, the opening and closing door allows the material to be tested to be laid flat, facilitating testing in the detection section and avoiding inaccurate test data caused by stacking. The filter holes, which hold excessively large particles within the screening mechanism, can be understood as particles larger than the filter holes remaining inside, while particles smaller than the filter holes pass through and enter the storage hopper. This separates large and small particles, allowing qualified small particles to be recycled and unqualified large particles to remain in the screening mechanism. When small particles enter the detection section from the storage hopper, the weight of the large particles is obtained through a weighing device. Combined with the total weight of the material to be tested, the proportion of large particles can be determined.

[0023] Furthermore, the detection section includes a conveying assembly, which includes a conveyor belt and a drive table for driving the conveyor belt. The detection assembly includes an image acquisition device, which is located above the conveyor belt. The conveyor belt is used to transport particles entering the detection section, and the upper surface of the conveyor belt is horizontal and forms a background screen.

[0024] In this technical solution, the conveyor belt is used to transport the material to be tested from the receiving section to the return section. The image acquisition device photographs the material on the conveyor belt to obtain data such as particle size or particle count. The upper surface of the conveyor belt forms the background for the photographing. Preferably, the material to be tested is dispersed rather than piled on the conveyor belt to facilitate the acquisition of data such as particle size or particle count. Compared to an inclined upper surface, a horizontal upper surface of the conveyor belt can prevent material particles from rolling off during the photographing process, thereby facilitating photographing and data acquisition.

[0025] Furthermore, the testing station also includes a support base, with fastening components on both sides of the support base, and the conveying assembly is fixed above the support base via the fastening components.

[0026] In this technical solution, the support base and the transmission component are connected by fasteners to form a detachable connection, which facilitates the replacement of the transmission component.

[0027] Furthermore, the support base is provided with a cleaning assembly, which includes at least a cleaning scraper and a wiping strip, so that the surface of the conveyor belt is cleaned after passing through the support base.

[0028] In this technical solution, the conveyor belt will be contaminated by material particles after multiple conveying processes. Since the surface of the conveyor belt serves as the background for the shooting, cleaning it with the cleaning component can ensure the cleanliness of the material particles in the shooting results, further improving the reliability of the detection results.

[0029] Furthermore, the return section is an inclined U-shaped groove, and the bottom of the return section is connected to the support base;

[0030] The return material section is located on the side near the detection section below the conveyor belt.

[0031] In this technical solution, the bottom of the material return section can be directly connected to the support base or connected via an indirect component. The side of the material return section closest to the detection end is located below the conveyor belt, allowing material particles on the conveyor belt to fall smoothly into the U-shaped trough, ensuring that all material particles in the detection section can be recycled back to the production line.

[0032] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0033] (1) This utility model achieves the automation of online sampling, testing and return of materials in the production line by setting up a support frame, sampling arm, testing table, feeding port, testing components and return port, which makes testing more convenient, greatly improves testing efficiency and saves manpower and testing time.

[0034] (2) The present invention enables the tested particles to flow back to the production line through the setting of the return port, so that even if the testing is frequent, the production output will not be affected, thereby improving the pass rate of the produced particles through multiple tests.

Detailed Implementation

[0040] The accompanying drawings are for illustrative purposes only and should not be construed as limiting the scope of this invention. To better illustrate the following embodiments, some components in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product. It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings.

[0041] Example 1

[0042] refer to Figure 1 and Figure 4 This embodiment provides a particle detection component for a continuous production line, comprising:

[0043] Erect supports for installation on the transmission path of production line 700;

[0044] The support frame is equipped with a movable sampling arm 200, which is used to sample along the transmission path;

[0045] The support frame is also equipped with a testing platform, which includes a material guiding channel;

[0046] The material guide channel is equipped with a detection component, a feeding port 312, and a return port connected to the transmission path.

[0047] refer to Figure 1 Preferably, the support frame includes a support rod 110 and a horizontal frame 120, a horizontal moving mechanism 121 is provided on the horizontal frame 120, and a lifting seat 122 is provided on the horizontal moving mechanism 121; the sampling arm 200 is disposed on the lifting seat 122.

[0048] The horizontal frame 120 is connected to the top of the support rod 110, which supports the horizontal frame 120 above the transmission path of the production line 700. The horizontal moving mechanism 121 moves the lifting seat 122 horizontally, thereby moving the sampling arm 200 on the lifting seat horizontally. The lifting seat 122 moves the sampling arm 200 longitudinally. This makes the movement of the sampling arm 200 more flexible, adaptable to more different specifications of the production line 700, meeting more diverse sampling needs, and improving applicability. For user manufacturers, this increases the utilization rate of the detection components in this solution. Furthermore, the entire sampling process does not require manual adjustment of the sampling arm 200's position, simplifying the sampling operation.

[0049] refer to Figure 1 and Figure 2Preferably, the sampling arm 200 includes: a shielding plate 210 and a sampling box 220; the shielding plate 210 is connected to the lifting seat 122 and forms at least a shield in the transmission direction and towards the detection table; the sampling box 220 is rotatably mounted on the shielding plate 210; the material storage height of the sampling box 220 is at least not less than the material thickness on the transmission path; a gap is left between the sampling box and the shielding plate 210.

[0050] The shielding plate 210 forms a barrier in the transmission direction. When sampling is to be performed at a specific location, the sample particles around it will not enter the sampling box 220 due to the shielding plate 210. The shielding plate 210 also forms a barrier on one side of the detection table, preventing samples flowing out of the return port from re-entering the sampling box 220. This improves the accuracy of sampling and the reliability of the test results. At the same time, since manual shielding is not required, the convenience of the sampling operation is also improved. The material storage height of the sampling box 220 is at least not less than the material thickness along the transmission path, meaning that the sampling box 220 can obtain the particle layer from the top to the bottom of the sampling section on the production line 700. Since large particles are usually located at the top and small particles at the bottom on the production line 700, this design ensures that particles of all sizes can be sampled evenly, thereby improving the representativeness of the sample. A gap is left between the sampling box and the shielding plate 210. By setting the interval, sufficient rotation space can be provided for the rotation of the sampling box 220, avoiding the influence of the shielding plate 210 on the rotation of the sampling box 220.

[0051] refer to Figure 3 Preferably, the testing platform includes: a material receiving section 300, a testing section 400, and a return section 500 connected sequentially from high to low; the feeding port 312 is located on the side of the material receiving section 300 away from the transmission path; the return port is located on the side of the return section 500 close to the transmission path; the testing component includes: a weighing device 320, which is mounted on the material receiving section 300.

[0052] refer to Figure 3 and Figure 4Specifically, the material receiving section 300 includes a material storage bin 310, which has an inclined surface. The material storage bin 310 has a discharge port 311 on the side near the detection section 400, and the discharge port 311 has an opening / closing door 313. The feeding port 312 is located at the top of the material storage bin 310. The weighing device 320 is located below the material storage bin 310 and is used to measure the weight change of the material storage bin 310. The opening / closing door 313 is rotatably mounted on the discharge port 311. When the opening / closing door 313 is open, it forms a scraper to flatten the material passing through the discharge port 311. The feeding port 312 has a screening mechanism 314 with multiple filter holes. The filter holes are used to retain excessively large particles within the screening mechanism 314.

[0053] refer to Figure 3 and Figure 4 The detection section 400 includes a conveying assembly, which includes a conveyor belt 410 and a drive table 420 for driving the conveyor belt 410. The detection assembly includes an image acquisition device 430, which is positioned above the conveyor belt 410. The conveyor belt 410 is used to transport particles entering the detection section 400, and its upper surface is horizontal, forming a background screen. The detection table also includes a support base 600, with fastening members 610 on both sides. The conveying assembly is fixed above the support base 600 via the fastening members 610.

[0054] refer to Figure 3 and Figure 4 The return section 500 is an inclined U-shaped trough 510, and the bottom of the return section 500 is connected to the support base 600; the side of the return section 500 near the detection section 400 is located below the conveyor belt 410.

[0055] refer to Figure 3 and Figure 4 Preferably, the support base 600 is provided with a cleaning component (not shown in the figure), which includes at least a cleaning scraper and a wiping strip, so that the surface of the conveyor belt 410 is cleaned after passing through the support base 600. The cleaning scraper first removes contaminants from the conveyor belt 410, and the wiping strip then wipes and cleans the conveyor belt to ensure that the surface of the conveyor belt 410 is clean.

[0056] In this embodiment, the particle detection component is used as follows: the sampling arm 200 samples from the transmission path of the production line 700; the horizontal moving mechanism 121 and the lifting seat 122 move the particle material to be tested to the feeding port 312 for feeding; large particles remain in the screening mechanism 314, and small particles remain in the storage bin 310; at this time, the opening and closing door 313 is closed, and the weighing device 320 obtains the total weight of the large and small particles; when the opening and closing door 313 is opened, the small particles roll from the storage bin 310 to the conveyor belt 410, and the weighing device 320 obtains the weight of the large particles, thereby calculating the proportion of large particles and obtaining the non-compliance rate data. The image acquisition device 430 takes pictures of the small particles on the conveyor belt 410 to obtain data information such as particle quantity and diameter. After the data is collected, the conveyor belt 410 conveys the small particles to the U-shaped trough 510, from which they roll back onto the production line 700.
