Description

Technical Field

[0001] This utility model relates to the field of capsule testing machine technology, specifically a waste capsule rejection module for a capsule testing machine. Background Technology

[0002] During the production process, empty capsules inevitably have various types of defects, mainly including excessive length or length, black spots on the surface, air bubbles, oil stains, wrinkles, pinch marks, brittleness, discoloration, burrs on the cut, and abnormalities inside the capsule. Therefore, capsules need to be inspected by a capsule inspection machine, and defective capsules need to be removed by a rejection module.

[0003] A search revealed a Chinese patent (CN102680491B) disclosing a rejection-type intelligent capsule inspection machine, comprising a feeding device, an electronic inspection device, a conveying device, a rejection device, a discharge device, a blowing and suction device, and a main control system. The feeding device, electronic inspection device, conveying device, rejection device, and blowing and suction device are electrically connected to the main control system. The feeding device is located at the beginning of the conveying device, and the discharge device is located at the end of the conveying device. The invention utilizes a feeding interface, a retaining wall, an air outlet, and a sensor probe to control the discharge speed, preventing excessive material accumulation in the storage box and thus affecting feeding. Multiple cameras work together to image different parts of the capsules, avoiding missed detections and improving inspection accuracy. The rejection device's air nozzle blows defective products out of the conveyor belt. The machine is simple in structure, fast, convenient, and does not damage the capsules.

[0004] The aforementioned patent proposes to install the air nozzle of the rejection device on the inside of the conveyor belt, and blow the waste capsules out from the inside to the outside of the conveyor belt through the air nozzle. However, in actual use, the installation of the air nozzle on the inside of the conveyor belt is limited by the installation space, which restricts its installation and disassembly, making it inconvenient. Moreover, when blowing out waste capsules, the movement channel of the capsule is short, and the capsule is easily rebounded by the air from the air nozzle, making it impossible for the capsule to be discharged from the conveyor belt. Therefore, we propose a waste capsule rejection module for a capsule detection machine. Utility Model Content

[0005] The technical problem to be solved by this application is that the air nozzle is installed on the inside of the conveyor belt. The installation space is limited during installation, which restricts its installation and disassembly, making it inconvenient. Moreover, when blowing out waste capsules, the channel is short, and the capsules are easily bounced by the air from the air nozzle, making it impossible for the capsules to be discharged from the conveyor belt. To address the aforementioned technical problems, this application provides a waste capsule rejection module for a capsule testing machine, comprising a conveyor belt and a mounting plate. The mounting plate is mounted on an outer support of the conveyor belt, and an air nozzle is mounted on the outer surface of the mounting plate. A discharge assembly is provided on the inner side of the conveyor belt support, comprising an L-shaped discharge pipe and a guide pipe. The L-shaped discharge pipe is positioned on the inner side of the conveyor belt support corresponding to the air nozzle, and the guide pipe is connected below the L-shaped discharge pipe. The guide pipe is inclined and one end extends to the outer side of the conveyor belt.

[0006] In some embodiments, the guide tube is provided with a flow guiding component, which is used to guide the waste capsule so that the waste capsule is discharged from the guide tube through the flow guiding component.

[0007] In some embodiments, the flow guiding assembly includes a support shaft and a flow guiding plate, the flow guiding plate being sleeved outside the support shaft and located inside the guide tube, the flow guiding plate being inclined.

[0008] In some embodiments, a vibrating assembly is installed inside the guide tube, and the guide plate is vibrated by the vibrating assembly to prevent the waste capsule from stagnating on the guide plate.

[0009] In some embodiments, the vibrating assembly includes a rotating shaft that is laterally rotatable inside a guide tube. A plurality of vibrating wheels are fitted on the outer surface of the rotating shaft. The plurality of vibrating wheels are all in contact with the bottom of the guide plate. The rotating shaft is connected to the eccentric part of the plurality of vibrating wheels. A motor is installed outside the guide tube, and the output end of the motor is connected to the rotating shaft.

[0010] In some embodiments, the rear side of the L-shaped discharge pipe is connected to a connecting box, and the support shaft is rotatably connected inside the connecting box.

[0011] In some embodiments, the support of the conveyor belt has a notch near the L-shaped discharge pipe.

[0012] This utility model has at least the following beneficial effects: 1. In this utility model, waste capsules are blown into the L-shaped discharge pipe through the air nozzle and discharged through the guide pipe. By installing the air nozzle on the outer side of the conveyor belt bracket, the installation of the air nozzle is not limited by space and is easy to install. By setting the L-shaped discharge pipe and the guide pipe, the blowing channel of the air nozzle is extended, avoiding the phenomenon of capsule rebound.

[0013] 2. In this utility model, the rotating shaft is driven by a motor to rotate, and the rotating shaft drives the vibrating wheel on it to rotate. When the end of the vibrating wheel away from the eccentric point rotates from below to above, it causes the vibrating wheel to lift one end of the guide plate. When the vibrating wheel detaches from the surface of the guide plate, one end of the guide plate falls downward due to its own weight. As the motor works, the guide plate vibrates continuously, preventing the capsules from stagnating inside the guide tube. This allows the capsules to pass through the guide plate and be discharged from the guide tube for unified collection. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Example 1: Please refer to Figure 1As shown in Figure 5, this utility model provides a technical solution: a waste capsule rejection module for a capsule testing machine, including a conveyor belt 1 and a mounting plate 2. The mounting plate 2 is mounted on a support on the outer side of the conveyor belt 1. An air nozzle 3 is mounted on the outer surface of the mounting plate 2. A discharge assembly is provided on the inner side of the support of the conveyor belt 1. The discharge assembly includes an L-shaped discharge pipe 4 and a guide pipe 5. The L-shaped discharge pipe 4 is located on the inner side of the support of the conveyor belt 1, corresponding to the air nozzle 3. The guide pipe 5 is connected to the lower part of the L-shaped discharge pipe 4. The guide pipe 5 is inclined and one end extends to the outer side of the conveyor belt 1. Specifically, the capsules are conveyed by the conveyor belt 1 and detected by the image captured by the camera in the previous process. The image data is transmitted to the main control system, which detects whether there are any defects inside the capsule. If the data is found to be unqualified, the main control system will calculate the time it takes for the capsule to reach the air nozzle 3 based on the rotation speed of the conveyor belt 1. Once the calculated time is reached, the main control system will send a command to the air nozzle 3 to blow air out of the capsule. The capsule enters the L-shaped discharge pipe 4 and is guided by the guide pipe 5. By installing the air nozzle 3 on the outer side of the conveyor belt 1 support, the installation of the air nozzle 3 is not limited by space and is easy to install. Furthermore, by setting the L-shaped discharge pipe 4 and the guide pipe 5, the blowing channel of the air nozzle 3 is extended, avoiding the phenomenon of capsule rebound.

[0018] The support of the conveyor belt 1 has a notch near the L-shaped discharge pipe 4. Specifically, by making the notch, the support of the conveyor belt 1 is prevented from blocking the capsule when the air nozzle 3 blows the capsule out.

[0019] Example 2: Based on Example 1, as follows Figures 1-5 As shown, this utility model provides a technical solution: In some embodiments, a flow guiding component 6 is provided inside the guide tube 5. The flow guiding component 6 is used to guide the waste capsule, so that the waste capsule is discharged from the guide tube 5 through the flow guiding component 6.

[0020] The flow guiding assembly 6 includes a support shaft 62 and a flow guiding plate 61. The flow guiding plate 61 is sleeved on the outside of the support shaft 62 and is located inside the guide tube 5. The flow guiding plate 61 is inclined. Specifically, when the capsule enters the guide tube 5 from the L-shaped discharge pipe 4, it falls onto the flow guiding plate 61, and the capsule is guided by the inclined flow guiding plate 61.

[0021] The rear side of the L-shaped discharge pipe 4 is connected to the connecting box 8, and the support shaft 62 is rotatably connected inside the connecting box 8. Specifically, the support shaft 62 is set inside the connecting box 8 so that one end of the guide plate 61 extends into the interior of the connecting box 8, so that the capsule can accurately fall onto the surface of the guide plate 61 when it falls from the L-shaped discharge pipe 4.

[0022] Example 3: Based on Example 1, such as Figures 1-5As shown, this utility model provides a technical solution: a vibration component is installed inside the guide tube 5, and the guide plate 61 is shaken by the vibration component to prevent the waste capsule from stagnating on the guide plate 61.

[0023] The vibratory assembly includes a rotating shaft 71 that is laterally rotatable inside the guide tube 5. Multiple vibratory wheels 72 are fitted onto the outer surface of the rotating shaft 71, and each vibratory wheel 72 is in contact with the bottom of the guide plate 61. The rotating shaft 71 is connected to the eccentric portion of each vibratory wheel 72. A motor 73 is installed outside the guide tube 5, and the output end of the motor 73 is connected to the rotating shaft 71. Specifically, the motor 73 drives the rotating shaft 71 to rotate, which in turn drives the vibratory wheels 72 to rotate. When the end of the vibratory wheel 72 furthest from the eccentric portion rotates from below to above, it lifts one end of the guide plate 61 upwards. After the vibratory wheel 72 detaches from the surface of the guide plate 61, one end of the guide plate 61 falls downwards due to its own weight. As the motor 73 operates, the guide plate 61 vibrates continuously, preventing the capsules from stagnating inside the guide tube 5. This allows the capsules to pass through the guide plate 61 and be discharged from the guide tube 5 for unified collection.

[0024] Based on the above embodiments, the following is the complete working principle of the above embodiments: During use, the camera captures and detects images from the preceding process, and transmits the image data to the main control system. The main control system detects whether there are any defects inside the capsule. If the detected data is deemed unqualified by the main control system, the system calculates the time it takes for the capsule to reach the air nozzle 3 based on the rotational speed of the conveyor belt 1. After the calculated time is reached, a command is sent to the air nozzle 3 to blow air out of the capsule. The capsule enters the L-shaped discharge pipe 4 and is guided by the guide pipe 5. By installing the air nozzle 3 on the outer side of the conveyor belt 1 support, the installation of the air nozzle 3 is not limited by space, facilitating its installation. Furthermore, by setting the L-shaped discharge pipe 4... The guide tube 5 extends the blowing channel of the air nozzle 3, preventing capsule rebound. After the capsule enters the guide tube 5, it falls onto the guide plate 61. The motor 73 drives the rotating shaft 71 to rotate, which in turn drives the vibrating wheel 72 on it to rotate. When the end of the vibrating wheel 72 away from the eccentric point rotates from below to above, it lifts one end of the guide plate 61 upward. After the vibrating wheel 72 detaches from the surface of the guide plate 61, one end of the guide plate 61 falls downward due to its own weight. As the motor 73 works, the guide plate 61 vibrates continuously, preventing the capsule from stagnating inside the guide tube 5. This allows the capsule to pass through the guide plate 61 and be discharged from the guide tube 5 for unified collection.
