[0030] Figure 1 This is a schematic structural diagram of a conveying device according to an embodiment of the present invention, such as... Figure 1 As shown, and with reference Figure 2 and 3 This utility model provides a conveying device for pills. The conveying device includes a pill screening machine 100, a collecting hopper 200, a pill refining machine 300, and a feeding device 400.

[0031] like Figure 2 As shown, the pellet screening machine 100 includes a housing 110 and a screening assembly 120 disposed inside the housing 110. The bottom of the housing 110 has a discharge port 111 so that the pellets screened by the screening assembly 120 can be discharged from the housing 110. The collecting hopper 200 is arranged with its opening facing upwards to collect the pellets.

[0032] like Figure 1 As shown, a receiving hopper 310 is formed on the pharmaceutical refining machine 300. The feeding device 400 is connected to the collecting hopper 200 through the pipeline 410 to transfer the pills in the collecting hopper 200 to the receiving hopper 310.

[0033] In this embodiment, the sieving machine 100 uses the sieving component 120 to screen out irregularly shaped pills that do not meet the requirements due to their small size, and discharges the screened pills from the box 110 through the discharge port 111 at the bottom of the box 110 to the collecting hopper 200. Since the two ends of the pipeline 410 are connected to the collecting hopper 200 and the receiving hopper 310 respectively, the feeding device 400 can suck the pills in the collecting hopper 200 to the receiving hopper 310, and then the pills enter the pharmaceutical refining machine 300 for further processing through the receiving hopper 310.

[0034] To ensure the normal operation of the shot sieving machine 100 and the pharmaceutical refining machine 300, and to prevent the high-temperature operation of the pharmaceutical refining machine 300 from affecting the pills in the shot sieving machine 100, the shot sieving machine 100 and the pharmaceutical refining machine 300 are spaced apart. This invention, through a pipe 410 connecting the feeding device 400 and the collecting hopper 200, can directly transport the pills to the pharmaceutical refining machine 300. This avoids the need for manual collection of irregularly shaped pills and subsequent transport to the pharmaceutical refining machine 300, facilitating the reprocessing of the pills and improving production efficiency.

[0035] In some embodiments of this utility model, such as Figure 2 As shown, there are multiple discharge ports 111 spaced apart. The conveying device also includes a conveying device 500, which is located on the lower side of the housing 110. All discharge ports 111 are located above the conveying device 500. The collecting hopper 200 is located downstream of the conveying device 500.

[0036] In this embodiment, the arrangement of multiple discharge ports 111 at intervals at the bottom of the box 110 significantly improves the discharge efficiency of the pills from the box 110. Furthermore, a conveying device 500 is provided below the discharge ports 111 to collect the pills falling from the discharge ports 111 onto the conveying device 500 into the collection hopper 200 located downstream of the conveying device 500, thereby improving the overall conveying efficiency of the conveying device.

[0037] Alternatively, in some embodiments of this utility model, multiple discharge ports 111 are respectively arranged above the conveying device 500 or the collecting hopper 200. That is to say, some pills can fall directly into the collecting hopper 200 through the discharge ports 111 located above the collecting hopper 200 without the need for conveying by the conveying device 500, thereby improving the collection efficiency of the pills.

[0038] In some embodiments of this utility model, such as Figure 2 As shown, the conveying device 500 includes a conveyor belt 510 and a collection hopper 200 disposed adjacent to the downstream side of the conveyor belt 510.

[0039] In this embodiment, after the conveyor belt 510 receives the pills falling from the discharge port 111, it conveys the pills to the collection hopper 200. The structure of conveying the pills by the conveyor belt 510 avoids the pills from getting stuck or blocked when being conveyed on the conveying device 500, and improves the conveying efficiency of the pills to the collection hopper 200.

[0040] In some embodiments of this utility model, the conveying device 500 includes an inclined feeding plate, a collecting hopper 200 connected to one end of the feeding plate, and the end of the feeding plate near the collecting hopper 200 is lower than the end away from the collecting hopper 200.

[0041] In this embodiment, the collecting hopper 200 is disposed adjacent to the downstream side of the feeding plate. After the pills fall onto the collecting plate, they roll into the collecting hopper 200 under the action of gravity, thus enabling the feeding plate to convey the pills. The structure of conveying pills through the feeding plate does not require additional electricity, saving energy and reducing costs.

[0042] In some embodiments of this utility model, the feeding device 400 includes a vacuum feeder 420, and the two ends of the pipeline 410 are respectively connected to the hopper 200 and the vacuum feeder 420.

[0043] In this embodiment, the pipeline 410, connected to the collecting hopper 200 and the vacuum feeder 420, forms a closed pipeline 410. That is, the pipeline 410 is a closed structure except for the openings at both ends. The operation of the vacuum feeder 420 in conjunction with the pipeline 410 is unaffected by height, allowing the pills to be transported from a lower to a higher position. This enables the pills in the lower collecting hopper 200 to be transferred to the higher receiving hopper 310, where they then fall into the pharmaceutical refining machine 300 for further processing. Furthermore, the closed pipeline 410 prevents contamination of the pills during transport within the pipeline, ensuring the quality of the pills.

[0044] In some embodiments of this invention, the vacuum feeder 420 is equipped with a vacuum hopper, creating a negative pressure inside the vacuum feeder 420, while the collecting hopper 200 at the feed inlet is at atmospheric pressure, forming a pressure difference. This pressure difference drives air to carry the pills through the pipe 410 and flow towards the vacuum hopper. The pills entering the vacuum hopper impact a filter screen located inside the vacuum hopper. Because the filter screen allows air to pass through while blocking solid pill particles, the pills fall to the bottom of the vacuum hopper.

[0045] In some embodiments of this invention, a level gauge is installed inside the vacuum hopper. When the pills in the vacuum hopper accumulate to a preset height, the level gauge detects a signal, which is sent to the control system. The control system then issues a command to stop the vacuum feeder 420. After the vacuum feeder 420 stops working, the pressure inside the vacuum hopper returns to normal. The discharge valve at the bottom of the vacuum hopper is opened, allowing the pills accumulated at the bottom of the hopper to fall into the refining machine 300 below by gravity. Finally, after discharge is completed, the discharge valve is closed.

[0046] In some embodiments of this utility model, the cross-sectional area of ​​the end of the pipe 410 connected to the hopper 200 is smaller than the cross-sectional area of ​​the end of the pipe 410 connected to the vacuum feeder 420.

[0047] In this embodiment, the cross-sectional area of ​​the pipe 410 connected to one end of the vacuum feeder 420 is larger, which improves the suction efficiency of the vacuum feeder 420 and makes the two ends of the pipe 410 have a larger pressure difference, thereby improving the suction efficiency.

[0048] When the cross-sectional area of ​​the end of the pipe 410 connected to the hopper 200 is large, multiple pills may enter at the same time, which may easily cause blockage of the pills in the pipe. However, by designing the cross-sectional area of ​​the end of the pipe 410 connected to the hopper 200 to be smaller, so that only one pill can enter at a time, the possibility of pills getting stuck in the pipe 410 is reduced. Moreover, since the pipe 410 gradually expands during the pill transportation process, the possibility of pills getting stuck in the pipe 410 is further reduced.

[0049] In some embodiments of this utility model, the feeding device 400 includes a screw conveyor, which is disposed inside the pipeline 410 to convey the pills to the receiving hopper 310.

[0050] In some embodiments of this utility model, the screening component 120 is a drum screen 121.

[0051] Alternatively, in some embodiments of this utility model, the screening component 120 is a vibrating screen.

[0052] In the two embodiments described above, the structure of screening out non-compliant irregularly shaped pills by means of drum screen 121 or vibrating screen is simple, does not require manual screening, and improves screening efficiency.

[0053] In addition, the drum screen 121 has low operating noise, which helps to improve the working environment of the factory where the shot sieve machine 100 is located.

[0054] In some embodiments of this utility model, such as Figure 3As shown, the drum screen 121 includes elastic support members 1211 at both ends, a cylinder 1212 with screen holes, and a drive shaft 1213. The two ends of the cylinder 1212 are rotatably connected to the two elastic support members 1211, which restrict the cylinder 1212 to move only in the vertical direction. The cylinder 1212 rotates via the drive shaft 1213, where an eccentric block 1214 is fixedly connected to the side wall of the drive shaft 1213. Due to the centrifugal force generated by the eccentric block 1214 during the rotation of the drive shaft 1213, and because the elastic support members 1211 restrict the vertical movement of the cylinder 1212, the drive shaft 1213 and the cylinder 1212 sway vertically during the rotation of the drive shaft 1213. This improves the screening efficiency when screening pills and reduces the occurrence of pill clogging of the screen holes.

[0055] In some embodiments of this utility model, bearings are provided at both ends of the drive shaft 1213. The elastic support member 1211 includes a spring and a limiting groove. One end of the spring is fixedly connected to the limiting groove, and the other end is fixedly connected to the bearing, so as to be rotatably connected to the drive shaft 1213 through the bearing.

[0056] In some embodiments of this utility model, the pellet sieving machine 100 and the pharmaceutical refining machine 300 are arranged at intervals, and the distance between the pellet sieving machine 100 and the pharmaceutical refining machine 300 is between 2m and 3m.

[0057] In this embodiment, the shot sieving machine 100 and the pharmaceutical refining machine 300 are spaced apart to ensure their normal operation and prevent the high-temperature operation of the pharmaceutical refining machine 300 from affecting the pills in the shot sieving machine 100. This also optimizes the layout of the conveying device in the factory, allowing workers to operate on the side of the pharmaceutical refining machine 300 and the shot sieving machine 100 that is closer to each other, facilitating maintenance of both machines. However, if the distance between the shot sieving machine 100 and the pharmaceutical refining machine 300 is too large, the pill conveying process between them will be difficult. Therefore, it is preferable to set the distance between the shot sieving machine 100 and the pharmaceutical refining machine 300 to be 2m to 3m.

[0058] In some embodiments of this utility model, the pipeline 410 is made of stainless steel. The stainless steel pipeline can withstand high temperatures and is not easily deformed, so as to ensure the normal delivery of the pills.

[0059] In some embodiments of this utility model, the collecting hopper 200 is located at one end of the shot sieving machine 100 near the pharmaceutical refining machine 300, and this end is the feeding end of the shot sieving machine 100, while the other end is the discharging end of the shot sieving machine 100. The discharging end of the shot sieving machine 100 is equipped with a screen box, on which an inclined screen is provided. The end of the screen near the conveying device 500 is lower than the other end, so that unqualified pills, i.e., oversized pills, are blocked on the upper side of the screen and then roll onto the conveying mechanism. Qualified pills that pass through the screen are then conveyed to the next process.

[0060] In some embodiments of this utility model, the screen box may also include a vibrating screen.

[0061] Therefore, those skilled in the art should recognize that although many exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications conforming to the principles of the present invention can be directly determined or derived from the disclosure of the present invention without departing from the spirit and scope of the present invention. Therefore, the scope of the present invention should be understood and recognized as covering all such other variations or modifications.
