Description

Technical Field

[0001] The present application relates to the technical field of screening of traditional Chinese medicine particles, and in particular to a centrifugal pill selection machine. Background Art

[0002] In the process of preparing traditional Chinese medicine granules, it is usually necessary to screen the vegetation pill particles, so as to screen out the light and irregular pill particles and obtain round and uniform-sized pill particles.

[0003] The commonly used screening equipment is the centrifugal pill separator. When in use, the pills are poured into the hopper. At this time, the pills flow out from the discharge port on one side of the hopper and fall on the spiral slide, thereby separating the light and irregular pills through centrifugal force.

[0004] When the pill particles flow out of the discharge port on the hopper, the discharge port is easily blocked, affecting the screening efficiency. Utility Model Content

[0005] In order to reduce the adverse effects on screening efficiency, the present application provides a centrifugal pill selecting machine.

[0006] The centrifugal pill selecting machine provided in this application adopts the following technical solution:

[0007] A centrifugal pill selecting machine comprises a machine body and a hopper which is arranged on the upper side of the machine body and opens upward, a discharge pipe is fixedly connected and communicated with the lower side of the hopper, the discharge pipe opening is located on the side away from the hopper, one end of the discharge pipe away from the hopper is inclined downward, a blocking plate for blocking the discharge pipe is provided at the opening of the discharge pipe, and a clearing component for clearing the discharge pipe is provided on the discharge pipe.

[0008] By adopting the above technical solution, the sealing plate is opened, and the pills in the hopper move along the length direction of the discharge pipe until they are separated from the discharge pipe from the opening of the discharge pipe. At this time, the clearing component on the discharge pipe continuously clears the pills in the discharge pipe, thereby reducing the possibility of the pills blocking the discharge pipe and reducing the adverse effects on the screening efficiency.

[0009] Optionally, the dredging assembly includes a plurality of dredging rods arranged along the length direction of the discharge pipe and perpendicular to the length direction of the discharge pipe, the dredging rods all pass through the discharge pipe and are slidably connected to the discharge pipe, and a moving part for driving the dredging rod to move is provided on the outer wall of the discharge pipe.

[0010] By adopting the above technical solution, the moving part drives the dredging rod to move in a direction perpendicular to the length of the material pipe. At this time, the dredging rod slides in the discharge pipe, thereby changing the position of the pills in contact with the dredging rod in the height direction of the discharge pipe, thereby reducing the possibility of pill accumulation in the discharge pipe.

[0011] Optionally, the moving member includes a moving frame located above the dredging rod. The upper ends of the dredging rods are fixedly connected to the lower side of the moving frame. One side of the discharge pipe is fixedly connected with a motor facing the moving frame. A rotating column is sleeved and fixedly connected to the output shaft of the motor. The rotation axis of the rotating column does not coincide with the output shaft of the motor. The rotating column is inserted into the moving frame and abuts against the two side walls of the moving frame parallel to the length direction of the discharge pipe. When the rotating column rotates, neither side of the moving frame perpendicular to the discharge pipe contacts the rotating column.

[0012] By adopting the above technical solution, the motor drives the rotating column to perform eccentric motion along the output shaft of the motor. Thus, during the process of the motor driving the rotating column to rotate, the rotating column continuously presses the two sides of the moving frame arranged parallel to the length direction of the discharge pipe, so that the moving frame drives the dredging rod to move in the length direction of the dredging rod, which is convenient for dredging the discharge pipe, reduces the possibility of pills blocking the discharge pipe, and reduces the adverse impact on the screening efficiency.

[0013] Optionally, two sides of the discharge pipe near one end of the blocking plate are fixedly connected with inserting plates perpendicular to the length direction of the discharge pipe. The ends of the inserting plates far away from the discharge pipe are bent towards each other. Both sides of the blocking plate are inserted between the bent ends of the inserting plates and the end wall of the discharge pipe.

[0014] By adopting the above technical solution, the blocking plate is slidably connected to the end wall of the discharge pipe through the inserting plates. When discharging materials, the blocking plate is driven to slide upwards, thereby driving the discharge pipe to open, and the opening size of the discharge pipe can be adjusted by the sliding position of the blocking plate, which is convenient for discharging materials.

[0015] Optionally, a guiding plate facing away from the hopper is fixedly connected to the lower side of the discharge pipe near one end of the blocking plate. The guiding plate is parallel to the length direction of the discharge pipe. When the blocking plate blocks the discharge pipe, the lower side of the blocking plate abuts against the guiding plate.

[0016] By adopting the above technical solution, when the pills flow out of the discharge pipe, they move onto the guiding plate. At this time, the guiding plate guides the pills, which is convenient for discharging materials. At the same time, the blocking plate abuts against the guiding plate, improving the stability of the blocking plate.

[0017] Optionally, the machine body includes a main rod arranged in the height direction. The lower end of the main rod is fixedly connected with a bottom plate. The lower side of the hopper is fixedly connected with the main rod. A slideway spirally wound around the main rod in multiple layers in the length direction of the main rod is fixedly connected to the main rod. A partition plate parallel to the height direction of the main rod is fixedly connected to the upper side of the end of the slideway far away from the hopper. The partition plate is arranged along the length direction of the end of the slideway far away from the hopper.

[0018] By adopting the above technical solution, the pills fall onto the slide through the discharge pipe and rotate downward along the length direction of the slide. At this time, the pills are subjected to centrifugal force during the rotation, so that the light pills are located on the side of the slide close to the main rod. When the pills rotate to near the partition plate, the partition plate separates the pills of uniform size from the light pills, reducing the possibility of light pills being mixed with pills of uniform size.

[0019] Optionally, the cross-sectional diameter of the lower side of each layer of the slideway along the height direction of the main rod gradually decreases toward the side away from the hopper.

[0020] By adopting the above technical solution, when the pills move along the slide, the shape of each layer of the slide increases the centrifugal force on the pills, thereby further facilitating the separation of light pills and improving the screening efficiency.

[0021] Optionally, a side of the blocking plate away from the guide plate is fixedly connected with a fixing portion facing away from the hopper.

[0022] By adopting the above technical solution, it is easy to drive the driving part to drive the blocking plate to move, thereby facilitating the opening or blocking of the discharge pipe and reducing the adverse effect on the screening efficiency.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. Open the blocking plate. The pills in the hopper move along the length of the discharge pipe until they are separated from the discharge pipe from its opening. The dredging component on the discharge pipe continuously dredges the pills in the discharge pipe, reducing the possibility of pills blocking the discharge pipe and the adverse effect on screening efficiency.

[0025] 2. The motor drives the rotating column to move eccentrically along the output shaft of the motor, so that when the motor drives the rotating column to rotate, the rotating column continuously squeezes the two sides of the moving frame arranged parallel to the length direction of the discharge pipe, so that the moving frame drives the dredging rod to move in the length direction of the dredging rod, thereby facilitating the dredging of the discharge pipe, reducing the possibility of pills blocking the discharge pipe, and reducing the adverse effects on the screening efficiency;

[0026] 3. When the pills flow out of the discharge pipe, they move to the guide plate. At this time, the guide plate guides the pills to facilitate feeding. At the same time, the blocking plate abuts against the guide plate to improve the stability of the blocking plate. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0030] The present application will be further described in detail below with reference to the accompanying drawings.

[0031] An embodiment of the present application discloses a centrifugal shot blasting machine. Refer to Figure 1 , a centrifugal shot blasting machine includes a machine body 1 and a hopper 2 arranged at the upper end of the machine body 1. The hopper 2 has an upward opening, and the lower end of the hopper 2 is set as a cone whose diameter gradually decreases towards one end close to the machine body 1. The machine body 1 includes a vertical main rod 11 with a height of 1 m, and the lower end of the hopper 2 is fixedly connected to the upper end of the main rod 11. One side of the hopper 2 close to the main rod 11 is fixedly connected with a discharge pipe 21 communicating with the inside of the hopper 2. The opening of the discharge pipe 21 is located at the end far from the hopper 2, and the end of the discharge pipe 21 far from the hopper 2 is inclined towards the direction close to the slideway 13.

[0032] A blocking plate 22 for blocking the discharge pipe 21 is provided at the end of the discharge pipe 21 far from the hopper 2. Plug-in plates 23 are fixedly connected to both sides of the discharge pipe 21 close to the blocking plate 22 and arranged in the vertical direction, and the ends of the plug-in plates 23 far from the discharge pipe 21 are bent towards each other at a right angle. The blocking plate 22 is plugged between the bent ends of the plug-in plates 23 and the end wall of the discharge pipe 21.

[0033] Refer to Figure 1 , a fixing part 221 perpendicular to the blocking plate 22 and facing away from the discharge pipe 21 is fixedly connected to the middle part on the upper side of the blocking plate 22, and a guiding plate 24 facing away from the hopper 2 is fixedly connected to the lower side of the discharge pipe 21 close to the blocking plate 22. When the blocking plate 22 blocks the discharge pipe 21, the lower side of the blocking plate 22 abuts against the upper side of the guiding plate 24, and a dredging component 3 for dredging the pills inside the discharge pipe 21 is provided on the discharge pipe 21.

[0034] A horizontal base 12 is fixedly connected to the lower end of the main rod 11, and a slideway 13 spirally wound around the main rod 11 in multiple layers is fixedly connected in the height direction of the main rod 11. In the embodiment of the present application, it is set to 6 layers. The lower sides of each layer of the slideway 13 are all conical shapes with diameters gradually decreasing (not shown in the figure), and the hole diameters of each layer of the slideway 13 in the horizontal direction gradually increase from the hopper 2 towards the direction close to the bottom plate.

[0035] Refer to Figure 1 , a vertical retaining edge 131 having the same shape as the slideway 13 is fixedly connected to the side of the slideway 13 away from the main rod 11, and a vertical partition plate 132 is fixedly connected to the upper side of the end of the slideway 13 close to the bottom plate. The partition plate 132 is located in the middle of the slideway 13 in the width direction. A first discharge port 133 is formed between the lower end of the slideway 13 and the side away from the main rod 11 and the partition plate 132, and a second discharge port 134 is formed between the side of the slideway 13 close to the main rod 11 and the partition plate 132. A first collecting hopper 14 adapted to the first discharge port 133 is fixedly connected to one side of the bottom plate, and a second collecting hopper 15 adapted to the second discharge port 134 is fixedly connected to the bottom plate.

[0036] The blocking plate 22 is driven to slide upward through the fixing part 221, so as to open the discharge pipe 21. At this time, the pills in the hopper 2 move along the length direction of the discharge pipe 21. At this time, the dredging assembly 3 on the discharge pipe 21 continuously dredges the pills in the discharge pipe 21, reducing the possibility of the pills blocking the discharge pipe 21. When the pills flow out of the discharge pipe 21, they move onto the guide plate 24. At this time, the guide plate 24 guides the pills until they fall onto the slideway 13 and rotate downward along the length direction of the slideway 13. The retaining edge 131 blocks the pills from falling. At this time, the pills are subjected to centrifugal force during the rotation process, so that the pills with light mass are located on the side of the slideway 13 close to the main rod 11, and the pills with uniform size are located on the side of the slideway 13 away from the main rod 11. Until they move to the partition plate 132, the pills with uniform size are separated from the pills with light mass. The pills with uniform size move through the first discharge port 133 into the first collecting hopper 14, and the pills with light mass move through the second discharge port 134 into the second collecting hopper 15, completing the pill selection.

[0037] The opening size of the discharge pipe 21 can be adjusted by the sliding position of the blocking plate 22, and when the blocking plate 22 blocks the discharge pipe 21, it abuts against the guide plate 24, improving the stability of the blocking plate 22. During the process of the pills moving along the slideway 13, the shape of each layer of the slideway 13 increases the centrifugal force received by the pills, facilitating the separation of the pills with light mass and improving the screening efficiency.

[0038] Refer to Figure 1 and Figure 2, the dredging component 3 includes a plurality of dredging rods 31 arranged along the length direction of the discharge pipe 21 and perpendicular to the discharge pipe 21. In the embodiment of the present application, two are provided and the diameter is 0.5 cm. The lower ends of the dredging rods 31 all pass through the discharge pipe 21 and are slidably connected to the side wall of the discharge pipe 21. A moving member 32 for driving the sliding of the dredging rod 31 is provided on the upper side of the discharge pipe 21.

[0039] The moving member 32 includes a moving frame 321 located at the upper end of the dredging rod 31, and the upper ends of the dredging rods 31 are fixedly connected to the lower side of the moving frame 321. A motor 322 facing the moving frame 321 is provided on one side of the discharge pipe 21. A fixing plate 323 is fixedly connected to the side of the discharge pipe 21 close to the motor 322. The motor 322 is fixedly connected to the fixing plate 323, and the output shaft of the motor 322 passes through the fixing plate 323 and is fixedly connected to a disc 324 whose axis coincides with the output shaft of the motor 322.

[0040] A driving rod 325 facing the moving frame 321 is fixedly connected to the axis of the disc 324 on the side away from the motor 322. An eccentrically arranged rotating column 326 is sleeved and fixedly connected to the driving rod 325. The rotating column 326 is inserted into the moving frame 321 and abuts against the two side walls of the moving frame 321 parallel to the length direction of the discharge pipe 21. When the motor 322 drives the rotating column 326 to rotate through the disc 324 and the driving rod 325, neither side of the moving frame 321 perpendicular to the length direction of the discharge pipe 21 contacts the rotating column 326.

[0041] The motor 322 drives the rotating column 326 to move eccentrically along the output shaft of the motor 322 through the disc 324 and the driving rod 325, and continuously squeezes the two sides of the moving frame 321 arranged parallel to the length direction of the discharge pipe 21, so that the moving frame 321 drives the dredging rod 31 to move in the length direction of the dredging rod 31, which is convenient for dredging the discharge pipe 21.

[0042] The implementation principle of a centrifugal pill - selecting machine in the embodiment of the present application is as follows: The fixing part 221 drives the blocking plate 22 to slide upward, thereby opening the discharge pipe 21. At this time, the pills in the hopper 2 move along the length direction of the discharge pipe 21. At this time, the motor 322 drives the rotating column 326 to move eccentrically along the output shaft of the motor 322 through the disc 324 and the driving rod 325, and continuously squeezes the two sides of the moving frame 321 arranged parallel to the length direction of the discharge pipe 21, so that the moving frame 321 drives the dredging rod 31 to move in the length direction of the dredging rod 31, which is convenient for dredging the discharge pipe 21.

[0043] The above are all the preferred embodiments of the present application. It does not limit the protection scope of the present application accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
