Description

Technical Field

[0001] The utility model relates to the technical field of pharmaceutical production, in particular to an automatic feeding device for pharmaceutical production. Background Art

[0002] Drugs can enter the human body through oral administration, injection, external application or other means to produce specific physiological effects. For drugs similar to some granular capsules, the raw materials need to be ground into powder first during production and then further sieved. In this process, a drug screening device will be used. The feeding device is a component of the drug screening device and is responsible for adding drugs or raw materials into the screening device for screening. Most of the existing feeding devices adopt a bucket-shaped structure design, which has certain drawbacks in use. Fine granular solid drug powder is easy to block the feeding pipe during feeding and requires manual cleaning, resulting in a reduction in feeding efficiency and inability to ensure the continuity of feeding. If an open feeding device is directly adopted, the one-time feeding amount is relatively large, the load on the screening device is large, and a large amount of dust is easily generated. In view of this, in-depth research on the above problems has led to the generation of this case. Summary of the Utility Model

[0003] Aiming at the deficiencies of the prior art, the utility model provides an automatic feeding device for pharmaceutical production, which solves the problems put forward in the background art.

[0004] To achieve the above purposes, the utility model is realized through the following technical solutions: An automatic feeding device for pharmaceutical production, including a powder bin and a screw conveyor arranged at the lower part of the powder bin. The screw conveyor is arranged in an inclined direction and the outlet end is vertically downward. The outlet end of the screw conveyor is connected to a temporary hopper. The lower part of the temporary hopper is connected to a feeding cylinder bin. The feeding cylinder bin is arranged horizontally and rectangular through slots are opened on the upper and lower sides. The lower end of the lower rectangular through slot is connected to a feeding through slot. The feeding through slot is connected to the screening device. An intermittent feeding mechanism is arranged in the feeding cylinder bin;

[0005] The intermittent feeding mechanism includes a fixed shaft, a sleeve seat, a baffle plate and a driving mechanism. The fixed shaft is rotatably inserted into the feeding cylinder bin and is coaxially arranged with the center of the feeding cylinder bin. The sleeve seat is fixedly sleeved on the outer side of the fixed shaft. The baffle plate is welded to the side wall of the sleeve seat along an annular array. The driving mechanism is arranged outside the feeding cylinder bin and the output end is connected to the fixed shaft.

[0006] The outlet end of the above screw conveyor is connected to the temporary hopper through a sealed connection member.

[0007] The above-mentioned sealed connection member includes a round-square transition pipe, an annular flange, and a rectangular flange. The annular flange is welded to the upper end of the round-square transition pipe and is assembled and connected to the outlet end of the screw conveyor. The rectangular flange is welded to the lower end of the round-square transition pipe and is assembled and connected to the temporary hopper.

[0008] An ultrasonic vibrator is assembled and connected to the side wall of the above-mentioned temporary hopper.

[0009] Blowing and sweeping assemblies are symmetrically arranged on the front and rear side walls of the above-mentioned feeding silo.

[0010] The above-mentioned blowing and sweeping assembly includes a V-shaped air duct, a sweeping pipe, and a jet nozzle. The V-shaped air duct is arranged on the front and rear sides of the feeding silo, and one end is connected to a high-pressure nitrogen storage tank through a solenoid valve. The sweeping pipes are arranged in a V-shape and are respectively communicated with the side walls of the V-shaped air duct. The jet nozzles are embedded in the front and rear side walls of the feeding silo and are communicated with the sweeping pipes.

[0011] The utility model provides an automatic feeding device for pharmaceutical production, which has the following beneficial effects: For the automatic feeding device for pharmaceutical production, the processed medicinal powder in the powder bin is directly introduced into the temporary hopper through a screw conveyor, and in cooperation with the intermittent feeding mechanism arranged in the feeding silo, the medicinal powder is continuously fed into the screening device. The intermittent feeding mechanism, through the cooperation of the baffle plates arranged in a ring shape and the feeding silo, when the opening part between the feeding plates is directly opposite to the position of the upper temporary hopper, the medicinal powder in the temporary hopper falls into the guiding space formed by the two feeding plates and the feeding silo. The fixed shaft continuously rotates. When the medicinal powder moves to the position of the falling through groove, it falls into the screening device under the action of gravity. The driving mechanism is used to adjust the rotation speed of the fixed shaft, thereby realizing the intermittent continuous feeding operation of the medicinal powder, which not only solves the problem that the feeding pipe of the traditional bucket-shaped feeding device is easily blocked, but also avoids the problem of a large one-time feeding amount of the open feeding device.

Detailed implementation manner

[0016] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0017] Embodiment: Combining the attached drawings of the specification Figures 1-3 As can be seen, the present application specifically designs an automatic feeding device for pharmaceutical production, including a powder bin 1 and a screw conveyor 2 arranged below the powder bin 1. The screw conveyor 2 is arranged in an inclined direction and the outlet end is vertically downward. The outlet end of the screw conveyor 2 is connected to a temporary hopper 3. The lower part of the temporary hopper 3 is connected to a feeding silo 4. The feeding silo 4 is arranged horizontally and rectangular through slots are opened on the upper and lower sides. The lower end of the lower rectangular through slot is connected to a blanking chute 5. The blanking chute 5 is connected to a screening device 6. An intermittent feeding mechanism is arranged in the feeding silo 4. The intermittent feeding mechanism includes a fixed shaft 7, a sleeve seat 8, a baffle plate 9 and a drive mechanism 10. The fixed shaft 7 is rotatably inserted into the feeding silo 4 and is coaxially arranged with the center of the feeding silo 4. The sleeve seat 8 is fixedly sleeved outside the fixed shaft 7. The baffle plate 9 is welded to the side wall of the sleeve seat 8 along an annular array. The drive mechanism 10 is arranged outside the feeding silo 4 and the output end is connected to the fixed shaft 7. The processed medicinal powder in the powder bin 1 is directly introduced into the temporary hopper 3 through the screw conveyor 2, and in cooperation with the intermittent feeding mechanism arranged in the feeding silo 4, the medicinal powder is continuously fed into the screening device 6. The intermittent feeding mechanism cooperates with the feeding silo 4 through the baffle plates 9 arranged in an annular shape. When the opening part between the baffle plates faces the position of the upper temporary hopper 3, the medicinal powder in the temporary hopper 3 falls into the guiding space formed by the two baffle plates and the feeding silo 4. The drive mechanism 10 is used to control the continuous rotation of the fixed shaft 7. When the medicinal powder moves to the position of the blanking chute, it falls into the screening device 6 under the action of gravity. The drive mechanism 10 adjusts the rotation speed of the fixed shaft 7, thereby realizing the intermittent continuous feeding operation of the medicinal powder, which not only solves the problem that the blanking pipe of the traditional bucket-shaped feeding device is easy to block, but also avoids the problem of a large one-time feeding amount of the open feeding device.

[0018] In the specific implementation process, as a preferred setting, the outlet end of the above-mentioned screw conveyor 2 is connected to the temporary hopper 3 through a sealing connection member. The sealing connection member includes a round-square transition pipe 11, an annular flange 12, and a rectangular flange 13. The annular flange 12 is welded to the upper end of the round-square transition pipe 11 and is assembled and connected to the outlet end of the screw conveyor 2. The rectangular flange 13 is welded to the lower end of the round-square transition pipe 11 and is assembled and connected to the temporary hopper 3. The upper end of the round-square transition pipe 11 is hermetically connected to the outlet end of the screw conveyor 2 through the annular flange 12, and the lower part of the round-square transition pipe 11 is hermetically connected to the temporary hopper 3 by using the rectangular flange 13. When the screw conveyor 2 feeds the powder into the temporary hopper 3, there will be no dust leakage, which can greatly improve the quality of the powder transfer and feeding operation and avoid powder waste at the same time.

[0019] In the specific implementation process, as a preferred setting, an ultrasonic vibrator 14 is assembled and connected to the side wall of the above-mentioned temporary hopper 3 to further improve the stability of the powder feeding downward in the temporary hopper 3 and increase the feeding speed.

[0020] In the specific implementation process, as a preferred setting, air injection and blowing components are symmetrically arranged on the front and rear side walls of the above-mentioned feeding silo 4. The air injection and blowing components include a V-shaped air guide pipe 15, a blowing pipe 16, and a jet nozzle 17. The V-shaped air guide pipe 15 is arranged on the front and rear sides of the feeding silo 4 and one end is connected to a high-pressure nitrogen storage tank through an electromagnetic valve. The blowing pipes 16 are arranged in a V shape and are respectively communicated with the side walls of the V-shaped air guide pipe 15. The jet nozzles 17 are embedded in the front and rear side walls of the feeding silo 4 and are communicated with the blowing pipes 16. Since the powder particles may be adsorbed on the baffle 9 during the transfer and feeding process, if not cleaned in time, it may affect the feeding operation efficiency. Therefore, the electromagnetic valve can be controlled to open and close automatically at a certain time interval, so as to blow the side wall of the baffle 9 with the high-pressure nitrogen in the high-pressure nitrogen storage tank. The high-pressure nitrogen enters the blowing pipe 16 through the V-shaped air guide pipe 15 and is further ejected through the jet nozzle 17. On the one hand, the blowing operation of the baffle 9 can be realized, and on the other hand, the feeding speed can be increased. Under the push of the gas, the powder can fall rapidly.

[0021] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
