[0002] The finished product detection device of the granule coating method production line is mainly used for quality detection of granule products after coating treatment to ensure that they meet relevant standards and requirements.

[0003] After searching, the Chinese patent with publication number CN115372374A discloses a pesticide granule coating method production line finished product detection device, which includes a base, and the base is provided with: a front end feeding assembly for feeding granule tablets to be detected; a guide assembly connected with the front end feeding assembly; a rear end feeding assembly connected with the guide assembly; a placement table; and a clamping member connected with the rear end feeding assembly, which can clamp and move the granule tablets to be detected by batches to the placement table; and an ultraviolet camera is fixedly arranged above the placement table and can shoot the entire placement table. The patent has the following advantages and effects: the tablets to be detected do not need to be placed at a specific position of the detection carrier by human, which is more convenient and ensures that the ultraviolet camera can irradiate the entire placement table; at the same time, the step of taking out the tablets to be detected from the detection carrier by human can be omitted, and the risk of pollution of the detection object caused by secondary contact is reduced.

[0004] However, the above-mentioned application has the following disadvantages:

[0005] In the above-mentioned device, the tablets cannot be placed in suspension, and there is a contact area between the tablets and the detection carrier. This part of the area cannot be detected by the ultraviolet camera, so there is a detection dead angle, which reduces the detection range of the ultraviolet camera for the tablets, affects the accuracy of detection, and if the detection efficiency needs to be improved, a large number of tablets need to be detected at the same time. When there are many tablets, they are easy to accumulate together, which further causes a dead angle between the tablets and the ultraviolet camera, further affects the accuracy of detection, and affects the use.

[0020] The granular coating production line finished product detection device provided by the application improves the prior art and has the following improvements and advantages:

[0021] Firstly, by arranging the driving mechanism, when the granular tablets are placed in the inside of the detection box, the driving motor can be started, the driving motor drives the transmission gear to rotate through the rotating shaft, the transmission gear is in meshing transmission with the transmission gear ring, the transmission gear ring in turn drives the inner driving ring to rotate, the inner driving ring in turn drives the detection box to rotate, the rotation of the detection box can make the granular tablets in the inside of the detection box turn over, thereby improving the detection range of the ultraviolet camera on the granular tablets and increasing the detection accuracy.

[0022] Secondly, through the design of the movable mechanism, when the drive mechanism rotates the detection box and the inner drive ring, the right inner drive ring can drive the movable gear to rotate via the right transmission gear ring. The movable gear can then drive the transmission shaft to rotate, which in turn drives the threaded sleeve to rotate inside the fixed block. Since the threaded sleeve and the fixed block are connected by a thread, the threaded sleeve can move in its axial direction, thereby driving the entire movable seat, the inner drive ring, and the detection box to reciprocate. The movable seat can move on the sliding shaft inside the movable groove. The reciprocating motion of the detection box can vibrate and flatten the granular tablets inside the detection box, preventing the granular tablets from accumulating inside the detection box and thus avoiding the situation where the granular tablets cannot be detected by the ultraviolet camera, further improving the accuracy of the detection.

[0023] Thirdly, this invention, through the setting of the feeding mechanism, allows the feeding motor to be started after the granular tablets are separated and transported by the feeding plate. The feeding motor drives the drive shaft to rotate, and the drive shaft is threadedly connected to the feeding pipe. The feeding pipe will then move downwards. When the bottom of the feeding pipe contacts the sealing plate, the sealing plate will flip downwards, causing the bottom of the feeding pipe to move into the detection box. At the same time, the feeding port on the feeding pipe will correspond to the feeding plate. At this time, the granular tablets on the feeding plate can enter the inside of the feeding pipe through the feeding port, and then enter the inside of the detection box through the feeding port. Meanwhile, the inside of the detection box is equipped with multiple distribution plates, and the granular tablets will enter between the multiple distribution plates, so that the granular tablets can be evenly distributed inside the granular tablet detection box. This achieves automatic and uniform feeding, while also ensuring uniform distribution of granular tablets and improving the detection effect.

[0024] Fourthly, this invention utilizes a blower mechanism. When the detection box rotates to flip the internal granular tablets, the connecting rod rotates with the detection box. The connecting rod is threadedly connected to the piston plate inside the air inlet pipe. As the detection box rotates, the piston plate moves inside the air inlet pipe, compressing the air inside. The compressed air enters the venturi tube through the connecting port and the air inlet pipe. Under the Venturi effect, outside air is drawn into the venturi tube through the air inlet and then enters the detection box through the check valve. At this time, any powder that may be present inside the detection box will leave the detection box with the airflow, thus achieving the effect of automatic dust removal when flipping the granular tablets.

[0025] Fifthly, this invention, through the setting of the sampling mechanism, when the granular tablets fall into the collection box, the collision between the granular tablets and the collection box may cause the granular tablets to break. At this time, dust can be formed inside the sampling box. Under the illumination of the searchlight on the image acquisition device two, the dust will be illuminated by the searchlight due to the Tyndall effect. Then, the image acquisition device two can be used to acquire images, which can then be compared with normal data to determine the strength of the coating of the current batch of granular tablets. If more dust appears, it indicates that the coating strength of the current granular tablets is low; conversely, if less dust appears, it indicates that the coating strength of the current granular tablets is high.

[0037] The present invention will now be described in detail, and the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0038] This invention provides an improved finished product testing device for a granule coating production line. The technical solution of this invention is as follows:

[0039] like Figures 1 to 8 As shown, this embodiment of the invention provides a finished product testing device for a granule coating production line, including a movable base 1, which is a rectangular plate. Two sets of mounting frames 2 are fixedly installed on the movable base 1. Each set of mounting frames 2 has two frames, which are symmetrically arranged on the movable base 1. An outer mounting ring 3 is fixedly installed between each set of mounting frames 2. The outer mounting ring 3 has a circular ring structure. An inner drive ring 4 is movably installed inside the outer mounting ring 3. The inner drive ring 4 has a circular ring structure. A detection box 5 is fixedly installed between the three inner drive rings 4. The detection box 5 has a hollow rectangular structure and is made of ultra-white glass. Multiple ultraviolet cameras 6 are evenly distributed and fixedly installed on the inner wall of the inner drive ring 4. When granule tablets are placed inside the detection box 5, the ultraviolet cameras 6 can then detect the surface coating of the granule tablets inside the detection box 5 using ultraviolet light. A drive mechanism is provided on the outer mounting ring 3, and a movable mechanism is provided on the movable base 1.

[0040] like Figure 2 and Figure 3 As shown, the drive mechanism includes a drive motor 7, a transmission cover 9, a transmission gear 10, a rotating shaft 11, and a transmission gear ring 12. The drive motor 7 is fixedly mounted on the middle outer mounting ring 3. The transmission cover 9 is a hollow cylindrical structure and is fixedly mounted on the middle outer mounting ring 3 at the position corresponding to the drive motor 7. The transmission gear 10 is a circular structure and is located inside the transmission cover 9. The rotating shaft 11 is a cylindrical structure and is fixedly mounted on the output end of the drive motor 7, and the rotating shaft 11 is fixedly connected to the transmission gear 10. There are two transmission gear rings 12, which are respectively embedded in the middle outer mounting ring 3. On the right outer mounting ring 3, the transmission gear 10 meshes with the transmission gear ring 12 on the middle outer mounting ring 3. Through the setting of the drive mechanism, when the granular tablets are placed inside the detection box 5, the drive motor 7 can be started. The drive motor 7 drives the transmission gear 10 to rotate through the rotating shaft 11. The transmission gear 10 meshes with the transmission gear ring 12, and the transmission gear ring 12 can then drive the inner drive ring 4 to rotate. The inner drive ring 4 can then drive the detection box 5 to rotate. The rotation of the detection box 5 can cause the granular tablets inside the detection box 5 to flip, thereby improving the detection range of the ultraviolet camera 6 for granular tablets and increasing the accuracy of the detection.

[0041] like Figure 2 and Figure 4As shown, the movable mechanism includes a base 13, a sliding shaft 15, a movable gear 16, a transmission shaft 17, a fixed block 18, and a threaded sleeve 19. The base 13 is a rectangular plate with a movable groove 14. The movable seat 1 is movably installed inside the movable groove 14. The sliding shaft 15 is cylindrical and is movably installed inside the movable groove 14, penetrating the side wall of the movable seat 1. The movable gear 16 is circular and is embedded inside the right outer mounting ring 3, meshing with the right transmission gear ring 12. The transmission shaft 17 is cylindrical and is fixedly connected to the movable gear 16. The fixed block 18 is a rectangular block. The threaded sleeve 19 is a cylindrical structure with reciprocating threads on its side wall and is fixedly sleeved on the transmission shaft 17. The fixed block 18 has threads inside that are compatible with the threaded sleeve 19. The groove and threaded sleeve 19 are movably installed inside the fixed block 18. Through the setting of the movable mechanism, when the drive mechanism drives the detection box 5 and the inner drive ring 4 to rotate, the right inner drive ring 4 can drive the movable gear 16 to rotate through the right transmission gear ring 12. The movable gear 16 can drive the transmission shaft 17 to rotate, and the transmission shaft 17 can then drive the threaded sleeve 19 to rotate inside the fixed block 18. Since the threaded sleeve 19 and the fixed block 18 are connected by threads, the threaded sleeve 19 can move in its axial direction, thereby driving the entire movable seat 1, the inner drive ring 4 and the detection box 5 to reciprocate. The movable seat 1 can move on the sliding shaft 15 inside the movable groove 14. The reciprocating motion of the detection box 5 can vibrate and flatten the granular tablets inside the detection box 5, avoiding the situation where the granular tablets accumulate inside the detection box 5 and cannot be detected by the ultraviolet camera 6, thus further improving the accuracy of detection.

[0042] like Figure 1 and Figure 5As shown, a feeding mechanism is provided above the movable seat 1. The feeding mechanism includes a transmission seat 20, a conveyor belt 21, a partition 22, a feeding hopper 23, a feeding plate 24, a dust cover 25, and a feeding pipe 26. The transmission seat 20 is a hollow structure and is located on the upper side of the movable seat 1. The conveyor belt 21 is movably installed inside the transmission seat 20 via a motor. Granule tablets can be moved by the conveyor belt 21. The partition 22 is an annular plate and is fixedly installed inside the transmission seat 20 at a position corresponding to the conveyor belt 21. The partition 22 can prevent granule tablets from falling off the sides of the conveyor belt 21. The feeding hopper 23 is a hollow trapezoidal structure that gradually decreases in size from top to bottom. The feeding plate 24 is a rectangular plate arranged at an angle, and the feeding plate 24 has openings on it. The conveyor belt 21 has multiple rectangular slots. After the granular tablets move to the position of the feeding plate 24 on the conveyor belt 21, they can be transported separately through the multiple rectangular slots on the feeding plate 24. The dust cover 25 is a hollow structure and is fixedly installed between the top of the feeding hopper 23 and the transmission seat 20. The dust cover 25 can prevent external dust from entering the interior of the feeding hopper 23 during transportation. The feeding pipe 26 is a hollow rectangular structure with its opening facing downwards. The feeding pipe 26 is movably installed inside the feeding hopper 23. The feeding pipe 26 has a feeding port 27 at the position corresponding to the position of the feeding plate 24. The feeding port 27 is a rectangular slot and communicates with the interior of the feeding pipe 26. The feeding motor 28 is fixedly installed on the top of the dust cover 25. A drive shaft 29 is fixedly installed on the output end of the device. The drive shaft 29 is a cylindrical structure with threads on its side wall. The drive shaft 29 passes downward through the top wall of the feed pipe 26 and is threadedly connected to the feed pipe 26. A feed inlet 30 is provided on the top of the detection box 5 corresponding to the position of the feed pipe 26. The feed inlet 30 is a rectangular groove that communicates with the interior of the detection box 5. A sealing plate 31 is movably installed on one side of the interior of the feed inlet 30 via a torsion spring shaft. The sealing plate 31 is a rectangular plate. Multiple distribution plates 32 are fixedly installed inside the detection box 5. The distribution plates 32 are rectangular glass plates. After the granular tablets are separated and transported by the feed plates 24, the feed motor 28 can be started, which drives the drive shaft 29 to rotate. The drive shaft 29 is threadedly connected to the feed tube 26, causing the feed tube 26 to move downwards. When the bottom of the feed tube 26 contacts the sealing plate 31, the sealing plate 31 flips downwards, moving the bottom of the feed tube 26 into the detection box 5. Simultaneously, the feed port 27 on the feed tube 26 aligns with the feed plate 24, allowing the granules on the feed plate 24 to enter the feed tube 26 through the feed port 27, and then through the feed inlet 30 into the detection box 5. The detection box 5 contains multiple distribution plates 32, allowing the granules to be evenly distributed within the detection box 5. This achieves both automatic and uniform feeding, as well as uniform distribution of the granules.And improve detection results.

[0043] like Figure 2 and Figure 7 As shown, a discharge port 33 is provided on the bottom wall of the detection box 5 away from the feed inlet 30. The discharge port 33 is a rectangular groove. A discharge shaft 34 is movably installed inside the discharge port 33. The discharge shaft 34 is a torsion spring shaft. A discharge plate 35 is fixedly sleeved on the discharge shaft 34. The discharge plate 35 is a rectangular plate. An electric push rod 36 is fixedly installed on the top wall of the detection box 5 at the position corresponding to the discharge shaft 34. The output end of the electric push rod 36 penetrates downward through the top wall of the detection box 5 and communicates with the inside of the detection box 5. When the granules are tested, the electric push rod 36 can be activated. The electric push rod 36 pushes the output end downward to squeeze the discharge plate 35. After being squeezed, the discharge plate 35 will flip. The flipping allows the granules inside the detection box 5 to be discharged through the discharge port 33, achieving the effect of rapid feeding.

[0044] like Figure 2 and Figure 6As shown, the test box 5 is equipped with a blower mechanism, which includes an air inlet pipe 48, a connecting rod 49, a first check valve pipe 50, a venturi pipe 51, a second check valve pipe 52, and an air inlet pipe 54. The air inlet pipe 48 is a hollow rectangular structure and is located on the left side of the test box 5. A support leg 8 is fixedly installed between the bottom of the air inlet pipe 48 and the movable seat 1. A rectangular piston plate is installed inside the air inlet pipe 48. The connecting rod 49 is a cylindrical structure and is fixedly installed on the left side wall of the test box 5 and located inside the air inlet pipe 48. The connecting rod 49 is threaded and passes through the piston plate. The check valve tube 50 is fixedly installed on the top right side of the air inlet pipe 48 and communicates with the inside of the air inlet pipe 48. The check valve tube 50 prevents air inside the air inlet pipe 48 from flowing to the outside, while allowing outside air to enter the air inlet pipe 48. The venturi tube 51 is embedded in the inside left side of the detection box 5. The check valve tube 52 is fixedly installed on the venturi tube 51 and communicates with the inside of the detection box 5. The check valve tube 52 allows air inside the venturi tube 51 to enter the inside of the detection box 5, while preventing air inside the detection box 5 from entering the venturi tube 51. A connection port 5 is provided on the inside right side of the connecting rod 49. 3. The connection port 53 is a T-shaped cylindrical groove, and the air inlet pipe 54 is a cylindrical structure. The air inlet pipe 54 is fixedly installed between the connecting rod 49 and the venturi tube 51. The air inlet pipe 54 connects the connection port 53 and the interior of the venturi tube 51. Air inlets 55 are provided on the left side of both the upper and lower walls of the detection box 5. The air inlets 55 are cylindrical grooves that extend into and connect with the interior of the venturi tube 51. Through the setting of the blower mechanism, when the detection box 5 rotates to flip the internal granular tablets, the connecting rod 49 will rotate with the detection box 5. The connecting rod 49 and the piston plate inside the air inlet pipe 48 are threaded together. As the detection box 5 rotates, the piston plate moves inside the air inlet pipe 48, compressing the air inside the air inlet pipe 48. The compressed air enters the venturi tube 51 through the connection port 53 and the air inlet pipe 54. Under the venturi effect, outside air is drawn into the venturi tube 51 through the air inlet port 55, and then enters the detection box 5 through the check valve pipe 52. At this time, any powder that may be present inside the detection box 5 will leave the detection box 5 with the airflow, thus achieving the effect of automatic dust removal when turning over granular tablets.

[0045] like Figure 1 , Figure 7 ,and Figure 8As shown, a comparison mechanism is provided on the right side of the detection box 5. The comparison mechanism includes a comparison box 37, a connecting cover 38, an air guide plate 39, a comparison plate 40, an image acquisition device 41, and a filter plate 47. The comparison box 37 is a hollow rectangular structure and is located on the right side of the detection box 5. The connecting cover 38 is a hollow trapezoidal structure, and its interior gradually decreases in size towards the comparison box 37. The connecting cover 38 is fixedly installed on the right side wall of the detection box 5. An opening is provided on the right side of the detection box 5, and the comparison box 37 and the connecting cover 38 communicate with the interior of the detection box 5. The filter plate 47 is fixedly installed on the right side of the interior of the detection box 5, and the holes in the filter plate 47 are smaller than the diameter of the granule tablets. The air guide plate 39 is an obliquely arranged plate and is fixedly installed on the lower left side of the interior of the comparison box 37. The comparison plate 40 is black. A rectangular plate is set at an angle. The comparison plate 40 is fixedly installed inside the comparison box 37. The image acquisition device 41 is obliquely embedded in the comparison box 37 at the position corresponding to the comparison plate 40. Through the setting of the comparison mechanism, when the powder inside the detection box 5 is blown to the right, the powder will move with the airflow to the inside of the connecting cover 38 and the comparison box 37. After being guided by the air guide plate 39, the powder and airflow will be blown onto the comparison plate 40. Since the comparison plate 40 is black, the powder will be very conspicuous on the comparison plate 40. At this time, the image acquisition device 41 can be used to acquire the image of the comparison plate 40, so as to acquire the amount of powder in the granules inside the detection box 5. Then it can be compared with normal data to know the breakage rate of this batch of granules inside the detection box 5.

[0046] The comparison mechanism also includes a comparison box 42, a receiving seat 43, a guide plate 44, a collection box 45, and an image acquisition device 46. The comparison box 42 is a hollow rectangular structure with a black interior. It is located on the right side of the movable seat 1. The receiving seat 43 is also a hollow rectangular structure, fixedly installed on the top of the comparison box 42 corresponding to the discharge plate 35. When the discharge plate 35 is flipped, it moves into the receiving seat 43, allowing the granules inside the detection box 5 to fall into the comparison box 42 through the receiving seat 43. The guide plate 44 is a triangular block, fixedly installed at the top inside the comparison box 42. The granules falling into the receiving seat 43 are guided by the guide plate 44 and fall towards the center of the comparison box 42. The collection box 45 is a hollow rectangular structure, embedded in the bottom inside the comparison box 42. Image acquisition device 2 46 is obliquely installed inside the upper part of image acquisition box 42, and a searchlight is provided on image acquisition device 2 46. Collection box 45 can collect granular tablets. Then, collection box 45 can be pulled out of the inside of image acquisition box 42 to process granular tablets. Due to the setting of the image acquisition mechanism, when granular tablets fall into the inside of collection box 45, the collision between granular tablets and collection box 45 may cause granular tablets to break. At this time, dust can be formed inside the image acquisition box 42. Under the illumination of the searchlight on image acquisition device 2 46, the dust will be illuminated by the searchlight under the Tyndall effect. Then, the image acquisition device 2 46 can be used to acquire images, which can then be compared with normal data to determine the strength of the coating of the current batch of granular tablets. If more dust appears, it means that the coating strength of the current granular tablets is low. Conversely, if less dust appears, it means that the coating strength of the current granular tablets is high.

[0047] Specific implementation steps: Through the setting of the drive mechanism, when the granular tablets are placed inside the detection box 5, the drive motor 7 can be started. The drive motor 7 drives the transmission gear 10 to rotate through the rotating shaft 11. The transmission gear 10 meshes with the transmission gear ring 12, which in turn drives the inner drive ring 4 to rotate. The inner drive ring 4 in turn drives the detection box 5 to rotate. The rotation of the detection box 5 can cause the granular tablets inside the detection box 5 to flip, thereby improving the detection range of the ultraviolet camera 6 for the granular tablets and increasing the accuracy of the detection.

[0048] Simultaneously, through the setting of the movable mechanism, when the drive mechanism drives the detection box 5 and the inner drive ring 4 to rotate, the right inner drive ring 4 can drive the movable gear 16 to rotate through the right transmission gear ring 12. The movable gear 16 can drive the transmission shaft 17 to rotate, and the transmission shaft 17 can then drive the threaded sleeve 19 to rotate inside the fixed block 18. Since the threaded sleeve 19 and the fixed block 18 are connected by threads, the threaded sleeve 19 can move in its axial direction, thereby driving the entire movable seat 1, the inner drive ring 4, and the detection box 5 to reciprocate. The movable seat 1 can move on the sliding shaft 15 inside the movable groove 14. The reciprocating motion of the detection box 5 can vibrate and flatten the granular tablets inside the detection box 5, avoiding the situation where the granular tablets accumulate inside the detection box 5 and cannot be detected by the ultraviolet camera 6, thus further improving the accuracy of detection.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention. Therefore, the invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
