Description

Technical Field

[0001] This application relates to the field of pill processing technology, and in particular to a self-controlled pill selection device. Background Technology

[0002] Water-honey pills, as one of the traditional dosage forms of traditional Chinese medicine, play an important role in clinical applications due to their convenient administration, accurate dosage, and ease of storage. In the production process of water-honey pills, the formed pills undergo a strict selection process to separate qualified products that meet the specified size and roundness requirements, and to remove unqualified products that are too large, too small, deformed, or stuck together, thus ensuring the uniformity of drug quality and the accuracy of dosage.

[0003] Currently, centrifugal shot separators are commonly used in the industry for screening water-honey shot. These separators primarily work by utilizing the centrifugal force exerted on larger shot particles as they move along the spiral structure; larger particles experience greater centrifugal force and move outwards, while smaller particles aggregate inwards. However, this type of separator requires workers to transport the shot particles to the top hopper of the centrifugal shot separator for feeding, resulting in low feeding efficiency. Summary of the Invention

[0004] To improve the efficiency of shot selection, this application provides an automated shot selection device.

[0005] The automated shot sorting equipment provided in this application adopts the following technical solution:

[0006] An automated shot selection device includes a feeding mechanism and multiple shot selection mechanisms. The feeding mechanism includes a central silo and multiple discharge pipes. The central silo is used to hold shot pellets. The bottom of the central silo is connected to the discharge pipes. The discharge pipes are equipped with electric valves. The shot selection mechanism includes a distribution silo. The distribution silo is connected to the discharge pipes. A first level sensor is installed inside the distribution silo.

[0007] By adopting the above technical solution, the central silo automatically opens and closes its feed pipe through a linkage between a first level sensor and an electric valve. When the material level in the distribution silos falls below a threshold, the silo is automatically replenished to prevent downtime due to empty silos; when full, the valve closes to prevent overflow, achieving automatic feeding and thus improving the feeding efficiency of the shot sorting system. Multiple independent shot sorting mechanisms are connected to the central silo via discharge pipes, supporting synchronous sorting operations and increasing the throughput per unit time.

[0008] Optionally, it also includes a feeding mechanism, which includes a feeding hopper and a vacuum pump. The feeding hopper is equipped with a feed pipe, which is connected to a central silo. The vacuum pump is connected to the central silo, and a second material level sensor is installed inside the central silo.

[0009] By adopting the above technical solution, the second material level sensor monitors the height of pellets in the central hopper in real time. When the material level is lower than the set threshold, the vacuum pump is automatically started to create a vacuum, and the pellets are sucked into the hopper through the feed pipe by negative pressure; the pump is automatically stopped when the hopper is full to avoid dry pumping or overload.

[0010] Optionally, the material distribution bin includes a main body, a discharge port, and a first motor. The discharge port is equipped with a stirring rod, and the output end of the first motor is connected to the stirring rod.

[0011] By adopting the above technical solution, a stirring roller is installed at the feeding port to avoid feeding interruption caused by pellet accumulation, thus achieving uniform discharge.

[0012] Optionally, a lifting mechanism is also included, which includes a fixed rod, a movable rod, and a first motor. The fixed rod is provided with a slide rail, one end of the movable rod is slidably mounted on the slide rail, and the other end is connected to the central hopper. The output end of the first motor is connected to the movable rod.

[0013] By adopting the above technical solution, the lifting mechanism uses a motor to drive the movable rod to slide on the fixed rod slide, and supports the lifting of the central hopper, which facilitates subsequent cleaning and maintenance.

[0014] Optionally, the shot selection mechanism includes a main rod and an angle adjustment section. The main rod has a spiral feed disc along its length. The angle adjustment section includes a first connecting rod, a second connecting rod, and an adjusting rod. The first connecting rod and the second connecting rod are respectively connected to the upper and lower adjacent side walls of the spiral feed disc. The first connecting rod has a first internal thread inside, and the second connecting rod has a second internal thread inside that rotates in the opposite direction to the first internal thread. The adjusting rod has external threads at both ends that match the first internal thread and the second internal thread. One end of the adjusting rod is located on the first connecting rod, and the other end is located on the second connecting rod.

[0015] By adopting the above technical solution, the reverse threads at both ends of the adjusting rod are engaged with the internal threads of the connecting rod. When the adjusting rod is rotated, the distance between the first connecting rod and the second connecting rod can be changed simultaneously, thereby adjusting the tilt angle of the spiral feed disc and improving the applicability to pills with different diameters, densities, and surface roughness.

[0016] Optionally, the bottom of the spiral feed disc is provided with a first discharge port and a second discharge port. The first discharge port is located on the outside of the spiral feed disc, and the second discharge port is located on the inside of the spiral feed disc and extends along the length of the main rod to the side below the first discharge port.

[0017] By adopting the above technical solution, the spiral feeder achieves sorting by utilizing the difference in centrifugal force when the pellets roll. Qualified pellets (high sphericity) have a large centrifugal force and move along the outer side of the spiral feeder, exiting from the first outlet; unqualified pellets have a small centrifugal force and roll along the inner side of the spiral feeder, being collected through the second outlet. The second outlet extends to the side and below the first outlet, forming a three-dimensional flow separation, avoiding pellet mixing caused by the traditional single outlet.

[0018] Optionally, it also includes a conveyor belt and a collection trough, wherein one end of the conveyor belt is connected to the first discharge port and the other end is connected to the collection trough.

[0019] By adopting the above technical solution, the conveyor belt is directly connected to the first discharge port (qualified pellet outlet) and the collection tank, realizing full automation of the sorting-conveying-collection process. Qualified pellets, after being sorted by the spiral feeder, do not require manual transfer and are directly fed into the collection tank via the conveyor belt, reducing production line downtime.

[0020] Optionally, the shot selection mechanism is provided with a support frame at the bottom, and the support frame is provided with multiple pulleys at the bottom.

[0021] By adopting the above technical solution, the pulley enables the shot selection mechanism to move freely, facilitating rapid adjustment of the shot selection mechanism's position.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. By setting up a central silo for unified material feeding, and linking the first material level sensor in the distribution silo with the electric valve, the feed pipe automatically opens and closes. When the material level in the distribution silo falls below the threshold, material is automatically replenished to avoid downtime due to an empty silo; when the silo is full, the valve closes to prevent overflow, achieving automatic material distribution and unloading, thereby improving production efficiency. Multiple independent shot sorting mechanisms are connected to the central silo via the unloading pipe, supporting synchronous sorting operations and increasing the throughput per unit time.

[0024] 2. The height of pellets in the central hopper is monitored in real time by a second material level sensor. When the material level is lower than the set threshold, the vacuum pump is automatically started to create a vacuum, and the pellets are sucked into the hopper through the feed pipe by negative pressure. The pump is automatically stopped when the hopper is full.

[0025] 3. By installing a stirring roller at the feeding port, the feeding interruption caused by pellet accumulation is avoided, thus achieving uniform discharge;

[0026] 4. By engaging the reverse threads at both ends of the adjusting rod with the internal threads of the connecting rod, the distance between the first and second connecting rods can be changed simultaneously when the adjusting rod is rotated, thereby achieving continuous adjustment of the spiral feed disc tilt angle and improving the applicability to pills with different diameters, densities, and surface roughness.

Detailed Implementation

[0034] The following is in conjunction with the appendix Figure 1 -Appendix Figure 6 This application will be described in further detail below.

[0035] This application discloses a self-controlled shot sorting device, referring to... Figures 1-2The system includes a feeding mechanism 1 and four shot sorting mechanisms 2. The feeding mechanism 1 includes a central silo 11 and multiple discharge pipes 12. The central silo 11 is used to hold the shot to be sorted. The bottom of the central silo 11 is connected to the discharge pipes 12, and the discharge pipes 12 are equipped with electric valves 121. The shot sorting mechanism 2 includes a distribution silo 21. The top of the distribution silo 21 is connected to the discharge pipes 12, and the distribution silo 21 is equipped with a first level sensor 2111. The level signal of the first level sensor 2111 is received by the central controller, which simultaneously controls the opening and closing of the electric valves 121. When the first level sensor 2111 senses that the level in the distribution silo 21 is lower than the threshold, the central controller controls the electric valves 121 to open, automatically replenishing the distribution silo 21 with shot, avoiding shutdown when the silo is empty. When the silo is full, the electric valves 121 are closed to prevent overflow, thus achieving automatic feeding.

[0036] Reference Figure 1 The system also includes a feeding mechanism 3. The feeding mechanism 3 includes a feeding hopper 31 and a vacuum pump 32. The feeding hopper 31 is equipped with a feed pipe 311, which is connected to a central silo 11. The vacuum pump 32 is connected to the central silo 11 via a vacuum conduit. A second level sensor 111 is installed inside the central silo 11 to detect the material level inside. The central controller receives the level signal from the second level sensor 111 and controls the vacuum pump 32 to start and stop. When the second level sensor 111 senses that the material level in the central silo 11 is below a threshold, the central controller controls the vacuum pump 32 to open, creating a negative pressure between the central silo 11 and the feed pipe 311, thereby drawing pellets into the central silo 11 and automatically replenishing it. When the silo is full, the vacuum pump 32 is turned off, achieving automatic feeding, dispensing, and unloading.

[0037] Reference Figure 3 The material distribution bin 21 includes a main body 211, a discharge port 212, and a first motor 213.

The angle adjustment section 23 includes a first connecting rod 231, a second connecting rod 232, and an adjusting rod 233. The first connecting rod 231 and the second connecting rod 232 are respectively connected to the upper and lower adjacent side walls of the spiral feed disc 221. The first connecting rod 231 has a first internal thread 2311 inside, and the second connecting rod 232 has a second internal thread 2321 inside, rotating in the opposite direction to the first internal thread 2311. The adjusting rod 233 has external threads 2331 at both ends that match the first internal thread 2311 and the second internal thread 2321, respectively. One end of the adjusting rod 233 is located on the first connecting rod 231, and the other end is located on the second connecting rod 232. The rotating adjustment rod 233 can shorten the distance between the first connecting rod 231 and the second connecting rod 232, thereby adjusting the tilt angle of the spiral feed disc 221 and improving its applicability to pills with different diameters, densities and surface roughness.

[0040] Reference Figure 5 The spiral feed disc 221 has a first discharge port 2211 and a second discharge port 2212 at its bottom. The first discharge port 2211 is located on the outer side of the spiral feed disc 221 and is used to screen out qualified pills. The second discharge port 2212 is located on the inner side of the spiral feed disc 221 and extends along the length of the main rod 22 to the side below the first discharge port 2211. The second discharge port 2212 is used to collect unqualified pills, avoiding material mixing caused by the traditional single outlet. (Refer to...) Figure 1 It also includes a conveyor belt 5 and a collection trough 6. One end of the conveyor belt 5 is connected to the first discharge port 2211, and the other end is connected to the collection trough 6, which can automatically transport qualified pills to the collection trough 6, realizing the full automation of the sorting-conveying-collection process.
