Description

Technical Field

[0001] The present application relates to the technical field of material conveying, and particularly relates to a medicinal vacuum feeding device. Background Art

[0002] A vacuum feeder is a dust-free closed pipeline conveying device that conveys granular or powdery materials by means of vacuum suction. Utilizing the air pressure difference between the vacuum and the ambient space, gas flow is formed in the pipeline to drive the powdery material to move, thereby completing the conveying of the powder. When manufacturing powdery drugs, a vacuum feeder is required for the feeding operation.

[0003] In the related art, a vacuum feeder is designed, which includes a vertical cylinder. An outlet is provided at the bottom of the vertical cylinder. A suction pump is connected to the top of the vertical cylinder through a pipeline. A suction pipe is connected to the side wall of the vertical cylinder through a pipeline. A mixer is also provided on the pipeline between the suction pipe and the vertical cylinder. A dust removal cloth bag is fixedly arranged on the inner wall of the vertical cylinder. During the feeding operation, the outlet is docked with the injection port of the reaction tank, the suction pipe is placed into the barrel storing the powdery drug, the suction pump is started, a negative pressure environment is formed between the vertical cylinder and the reaction tank, the suction pipe extracts the powdery drug, the powdery drug and air are mixed by the mixer and then enter the vertical cylinder. The powdery drug is blocked by the dust removal cloth bag and cannot enter the suction pump. Due to gravity and the limited negative pressure wind force in the vertical cylinder, it starts to fall and falls into the reaction tank from the outlet at the bottom of the vertical cylinder to complete the feeding.

[0004] During the implementation of the present application, it is found that at least the following problems exist in this technology: During the feeding operation, it is necessary to maintain the docking state between the outlet and the injection port of the reaction tank, but there is a lack of a reliable connection structure between the vertical cylinder and the reaction tank. Once the vertical cylinder is interfered by an external force, the outlet and the injection port of the reaction tank may be separated from each other, and external air will instantly rush into the vertical cylinder and the reaction tank, causing the powdery drug to spill and posing a safety hazard. Utility Model Content

[0005] In order to improve the connection stability between the vertical cylinder and the reaction tank during the feeding operation and improve the safety of the feeding process, the present application provides a medicinal vacuum feeding device.

[0006] The medicinal vacuum feeding device provided by the present application adopts the following technical solutions:

[0007] A medicinal vacuum feeding device includes a vertical cylinder. An outlet is provided at the bottom of the vertical cylinder. A plurality of support blocks are arranged on the vertical cylinder, and all the support blocks are symmetrically arranged at the center on the outer wall of the vertical cylinder. A grasping rod is connected to the support block. One end of the grasping rod is rotatably matched with the support block. A clamping block is arranged at the other end of the grasping rod. The clamping block is used to press against the outer wall of the reaction tank. A pressing component is arranged on the grasping rod. The pressing component is used to drive the grasping rod to deflect and lock.

[0008] By adopting the above technical solution, during the feeding operation, after docking the discharge port with the charging port of the reaction tank, the clamping rod is driven to deflect and lock by the pressing component, and the clamping block approaches and presses against the outer wall of the reaction tank. Under the combined action of multiple clamping rods, the clamping block applies a pressing force from different circumferential directions of the reaction tank, and all the clamping blocks clamp and fix the reaction tank. At this time, the vertical cylinder is reliably connected to the reaction tank through the clamping rod, thereby improving the connection stability between the vertical cylinder and the reaction tank during the feeding operation and enhancing the safety of the feeding process.

[0009] Preferably, the clamping block is rotatably matched with the clamping rod.

[0010] By adopting the above technical solution, when using the present application to dock and fix reaction tanks with different outer diameters, since the clamping block and the clamping rod are rotatably matched, the clamping block can automatically adapt to the outer wall of the reaction tank and fit with the outer wall of the reaction tank, so as to improve the connection stability between the present application and reaction tanks with different diameters and expand the application range of the present application.

[0011] Preferably, the clamping rod is bent towards the side close to the vertical cylinder.

[0012] By adopting the above technical solution, the clamping rod is bent towards the side close to the vertical cylinder, so that there is a larger reserved space inside the clamping rod, minimizing the contact between the top edge of the reaction tank and the rotating rod and ensuring that the movement of the clamping rod is not interfered by the reaction tank.

[0013] Preferably, the pressing component includes an adjusting block, a sliding pin, and a threaded rod. The clamping rod is provided with an adjusting hole along its length direction. The adjusting block is arranged in the adjusting hole. A sliding groove is provided on the side wall of the adjusting hole. One end of the sliding pin is rotatably and slidably arranged in the sliding groove, and the other end of the sliding pin is fixedly connected to the side wall of the adjusting block. The threaded rod is rotatably arranged on the outer side wall of the vertical cylinder, and the threaded rod is threadedly engaged with the adjusting block.

[0014] By adopting the above technical solution, when it is necessary to drive the clamping rod to deflect towards or away from the vertical cylinder, the threaded rod is driven to rotate. The threaded rod is threadedly engaged with the adjusting block and drives the adjusting block to approach or move away from the vertical cylinder. The sliding pin and the sliding groove are in a rotational and sliding fit. The adjusting block deflects and slides simultaneously in the adjusting hole. In this way, the adjusting block drives the clamping rod to deflect towards or away from the vertical cylinder, and the threaded rod also has a locking effect on the adjusting block, forming a stable triangular structure among the threaded rod, the clamping rod, and the vertical cylinder, improving the connection reliability between the vertical cylinder and the reaction tank.

[0015] Preferably, a first gear is coaxially fixed on the threaded rod. A rotating ring is sleeved outside the vertical cylinder. The rotating ring is rotatably connected to the vertical cylinder. A first toothed ring is fixedly arranged on the top of the rotating ring, and the first toothed ring is meshed with all the first gears.

[0016] By adopting the above technical solution, the rotating ring is driven to rotate. The first toothed ring at the top of the rotating ring meshes with all the first gears, driving all the first gears to rotate together, and the rotating directions of all the first gears are the same and the rotation angles are equal. Thus, by only driving the rotating ring to rotate, all the gripping rods can be driven to deflect together, and the activities among all the gripping rods are synchronized.

[0017] Preferably, a second toothed ring is fixedly arranged at the bottom of the rotating ring. An adjusting rotating shaft is rotatably arranged on the outer side wall of the vertical cylinder. A second gear is coaxially fixed on the adjusting rotating shaft. The second toothed ring meshes with the second gear. A knob is fixedly arranged at one end of the adjusting rotating shaft away from the vertical cylinder.

[0018] By adopting the above technical solution, when the knob is turned, the knob applies a torsional force to the adjusting rotating shaft, thereby driving the second gear to rotate. The second toothed ring rotates and meshes with the second gear, and the rotating ring rotates under the influence of the second toothed ring. Thus, it is convenient to apply a torsional force to the rotating ring from one side of the vertical cylinder, and the interference of the hand on the activities of the gripping rods is avoided as much as possible when directly rotating the rotating ring.

[0019] Preferably, a rubber pad is fixedly arranged on the inner side wall of the clamping block.

[0020] By adopting the above technical solution, the rubber pad inside the clamping block, on the one hand, helps to increase the friction between the clamping block and the reaction tank, further improving the connection stability between the vertical cylinder and the reaction tank; on the other hand, it plays a buffering role between the reaction tank and the clamping block to protect the outer wall of the reaction tank.

[0021] Preferably, a hanging handle is fixedly arranged at the top of the vertical cylinder.

[0022] By adopting the above technical solution, when separating the vertical cylinder from the reaction tank, the vertical cylinder can be lifted through the hanging handle, which is convenient for applying a lifting force to the vertical cylinder.

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

[0024] 1. By arranging the vertical cylinder, the discharge port, the support block, the gripping rod, the clamping block, and the tightening component, the tightening component drives the gripping rod to deflect and lock. Under the common action of multiple gripping rods, the clamping block applies a tightening force from different circumferential directions of the reaction tank, and all the clamping blocks clamp and fix the reaction tank. Thus, when performing the feeding operation, the connection stability between the vertical cylinder and the reaction tank is improved, and the safety of the feeding process is improved;

[0025] 2. By arranging the adjusting block, the sliding pin, the threaded rod, the adjusting hole, and the sliding groove, the control of the deflection movement of the gripping rod in the direction close to or away from the vertical cylinder is realized. The threaded rod also has a locking effect on the adjusting block, forming a stable triangular structure among the threaded rod, the gripping rod, and the vertical cylinder, improving the reliability of the connection between the vertical cylinder and the reaction tank;

[0026] 3. By setting the first gear, rotating ring, first toothed ring, second toothed ring, knob, and second gear, simply driving the knob to rotate makes it easy to apply a torsional force to the rotating ring from one side of the vertical cylinder, which can drive all the gripping rods to deflect together, and the activities of all the gripping rods are synchronized.

[0030] The following will further elaborate on the present application in conjunction with the attached Figure 1-2 drawings.

[0031] An embodiment of the present application discloses a medicinal vacuum feeding device. Referring to Figure 1 , it includes a vertical cylinder 1. A discharge port 11 is provided at the bottom of the vertical cylinder 1, and a suction pipeline for connecting to a suction pump is reserved at the top of the vertical cylinder 1. A hanging handle 15 for lifting the vertical cylinder 1 is also fixedly provided at the top of the vertical cylinder 1, and a suction pipeline for connecting to a suction pipe is reserved on the side wall of the vertical cylinder 1. A dust removal cloth bag is also provided inside the vertical cylinder 1, and the dust removal cloth bag is located between the suction pipeline and the suction pump pipeline.

[0032] Referring to Figure 1 and Figure 2 , three support blocks 12 are provided on the vertical cylinder 1, and the three support blocks 12 are symmetrically arranged at the center on the outer wall of the vertical cylinder 1. A gripping rod 2 is connected to the support block 12. One end of the gripping rod 2 is rotatably fitted with the support block 12, and a clamping block 21 is rotatably provided at the other end of the gripping rod 2. The clamping block 21 is used to tightly press against the outer wall of the reaction tank. A rubber pad 212 is fixedly provided on the inner side wall of the clamping block 21. The rubber pad 212 helps to increase the friction between the clamping block 21 and the reaction tank and plays a buffering role between the reaction tank and the clamping block 21 to protect the outer wall of the reaction tank. The gripping rod 2 is bent towards the side close to the vertical cylinder 1 to increase the space inside the gripping rod 2 and ensure the movement range of the gripping rod 2. A tightening component 3 is provided on the gripping rod 2, and the tightening component 3 is used to drive the gripping rod 2 to deflect and lock.

[0033] Referring toFigure 1 With Figure 2 , after docking the discharge port 11 with the charging port of the reaction tank, the driving rod 2 is driven by the tightening component 3 to deflect towards the vertical cylinder 1, so that the clamping block 21 approaches the outer wall of the reaction tank. The outer wall of the reaction tank blocks the clamping block 21, forcing the clamping block 21 to deflect, so that the rubber pad 212 inside the clamping block 21 faces and approaches the outer wall of the reaction tank until the clamping block 21 and the outer wall of the reaction tank are tightly pressed against each other. Under the combined action of multiple driving rods 2, the clamping blocks 21 apply a tightening force from different circumferential directions of the reaction tank, thereby clamping and fixing the reaction tank. In this way, when the feeding operation is carried out, the connection stability between the vertical cylinder 1 and the reaction tank is improved, and the safety of the feeding process is improved.

[0034] To facilitate driving the driving rod 2 to deflect and lock, referring to Figure 1 , the tightening component 3 includes an adjusting block 31, a sliding pin 311, and a threaded rod 32. An adjusting hole 22 is provided along the length direction on the upper half of the driving rod 2, and the adjusting block 31 is arranged in the adjusting hole 22. A sliding groove 221 is provided on the side wall of the adjusting hole 22. One end of the sliding pin 311 rotates and slides in the sliding groove 221, and the other end of the sliding pin 311 is fixedly connected to the side wall of the adjusting block 31. The threaded rod 32 is rotatably arranged on the outer side wall of the vertical cylinder 1, and the threaded rod 32 is threadedly engaged with the adjusting block 31.

[0035] Referring to Figure 1 , by driving the threaded rod 32 to rotate, the threaded rod 32 is engaged with the adjusting block 31 and drives the adjusting block 31 to approach or move away from the vertical cylinder 1. The adjusting block 31 simultaneously deflects and slides in the adjusting hole 22, and the adjusting block 31 drives the driving rod 2 to deflect. The threaded rod 32 also has a locking effect on the adjusting block 31, forming a stable triangular structure among the threaded rod 32, the driving rod 2, and the vertical cylinder 1, improving the reliability of the connection between the vertical cylinder 1 and the reaction tank.

[0036] To facilitate synchronous control of all the driving rods 2, referring to Figure 1 , a first gear 321 is coaxially fixed on each threaded rod 32. A rotating ring 13 is sleeved outside the vertical cylinder 1, and the rotating ring 13 is rotatably connected to the vertical cylinder 1. A first toothed ring 131 is fixedly arranged on the top of the rotating ring 13, and the first toothed ring 131 is meshed with all the first gears 321. Driving the rotating ring 13 to rotate, the first toothed ring 131 on the top of the rotating ring 13 is meshed with all the first gears 321, driving all the first gears 321 to rotate together. Therefore, by only driving the rotating ring 13 to rotate, all the driving rods 2 can be driven to deflect together, facilitating synchronous control of all the driving rods 2.

[0037] To minimize interference of the hand on the movement of the driving rod 2 when directly rotating the rotating ring 13, referring to Figure 1, a second gear ring 132 is fixedly arranged at the bottom of the rotating ring 13, an adjusting rotating shaft 14 is rotatably arranged on the outer side wall of the vertical cylinder 1, a second gear 142 is coaxially fixed on the adjusting rotating shaft 14, the second gear ring 132 is meshed with the second gear 142, and a knob 141 is fixedly arranged at one end of the adjusting rotating shaft 14 away from the vertical cylinder 1. When the knob 141 is turned, a torsional force is applied to the adjusting rotating shaft 14, and the second gear 142 is driven to rotate. The second gear ring 132 is meshed with the second gear 142 to drive the rotating ring 13 to rotate, which avoids the interference of the hand on the movement of the grasping rod 2 when the rotating ring 13 is directly rotated.

[0038] The implementation principle of a medicinal vacuum feeding device according to an embodiment of the present application is as follows: during the feeding operation, the discharge port 11 is docked with the feeding port of the reaction tank. When the knob 141 is turned, the adjusting rotating shaft 14 rotates and drives the second gear 142 to rotate. The second gear ring 132 drives the rotating ring 13 to rotate as it meshes with the second gear 142. At this time, the first gear ring 131 at the top of the rotating ring 13 meshes with all the first gears 321, driving all the first gears 321 to rotate together, and all the threaded rods 32 also rotate together. The threaded rod 32 meshes with the adjusting block 31 and drives the adjusting block 31 to approach the reaction tank. The adjusting block 31 simultaneously deflects and slides in the adjusting hole 22, and pulls the sliding groove 221 through the sliding rod, pulling the grasping rod 2 to deflect towards the vertical cylinder 1. The clamping block 21 approaches and presses against the outer wall of the reaction tank. Under the combined action of multiple grasping rods 2, the clamping block 21 applies a pressing force from different circumferential directions of the reaction tank, and all the clamping blocks 21 clamp and fix the reaction tank. In this way, during the feeding operation, the connection stability between the vertical cylinder 1 and the reaction tank is improved, so as to improve the safety of the feeding process.

[0039] The above are all the preferred embodiments of the present application. The protection scope of the present application is not limited by this. 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.
