Description

Technical Field

[0001] This utility model belongs to the technical field of feeding equipment, and relates to a feeding equipment for raw materials used in the synthesis of powdered pharmaceuticals. Background Technology

[0002] Butanol black powder is usually a white to grayish-white powder. When preparing butanol black powder, multiple raw materials need to be added to the reaction vessel in a certain proportion, so feeding equipment is used.

[0003] Chinese utility model patent CN219384076U discloses a quantitative phosphorus pentoxide feeding device, including a feeding tank. A conveying pipe is connected through and fixedly to the center of the top of the feeding tank. An electronic weighing device is fixedly connected to the middle of the inner wall of the feeding tank. A weighing tube is connected through and fixedly to the center of the electronic weighing device. A drive shaft is rotatably connected through and fixedly to the center of the outer diameter of the weighing tube. A storage plate is connected through and fixedly to the rear end of the outer diameter of the drive shaft. This feeding device allows material to fall onto the storage plate by opening a solenoid valve. A motor drives the storage plate to rotate and pour out the material from the storage plate. Because the material on the storage plate comes into contact with the inner wall of the weighing tube, material residue adheres to the inner wall of the weighing tube, resulting in inaccurate raw material feeding.

[0004] Therefore, there is an urgent need to design a raw material feeding device for the synthesis of powdered pharmaceuticals that can reduce raw material residue in the weighing tube and make feeding more accurate. Utility Model Content

[0005] To address the problems existing in the background technology, this utility model proposes a raw material feeding device for the synthesis of powdered drugs.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A raw material feeding device for the synthesis of powdered drugs includes a feeding tank, a weighing tube that slides vertically through the bottom surface of the feeding tank, and a feed pipe that is fixedly inserted through the top surface of the feeding tank, with the bottom end of the feed pipe extending downwards into the top end of the weighing tube.

[0008] The weighing tube is equipped with a rotating plate inside, and several scrapers are slidably arranged on the inner wall of the weighing tube. A driving assembly is provided on the weighing tube, which can drive the plate to rotate in the vertical direction and drive the scrapers to rotate in the horizontal direction.

[0009] A sleeve is fixedly installed at the end of the placement plate, and several sliding rods slide evenly through the sleeve. A striking block is fixedly connected to one end of each sliding rod that extends into the sleeve. A transmission component is installed on the weighing tube. When the sleeve rotates, the transmission component drives several sliding rods to slide on the sleeve in sequence.

[0010] Furthermore, an annular electronic weighing device is fixedly installed on the inner wall of the feeding tank. The weighing tube is located inside the electronic weighing device, and two support rods are symmetrically fixedly connected to the outer surface of the weighing tube. Both support rods are fixedly connected to the top of the electronic weighing device.

[0011] Furthermore, a toothed ring is coaxially rotatably connected to the top of the weighing tube, and several scrapers are fixedly connected to the bottom of the toothed ring;

[0012] The weighing tube is internally connected to a connecting ring, and several scrapers are fixedly connected to the top of the connecting ring. The placement plate is movably disposed inside the connecting ring.

[0013] Furthermore, the drive assembly includes a motor, which is fixedly connected to the outer surface of the bottom of the weighing tube. A connecting rod is fixedly connected to the output end of the motor, and a spur gear is coaxially fixedly connected to the top end of the connecting rod. The spur gear meshes with a gear ring.

[0014] Furthermore, a rotating shaft is rotatably passed through the weighing tube, and the placement plate is fixedly sleeved on the rotating shaft. A second bevel gear is coaxially and fixedly connected to one end of the rotating shaft.

[0015] A first bevel gear is fixedly sleeved on the connecting rod, and the first bevel gear meshes with a second bevel gear.

[0016] Furthermore, the sleeve is fixedly fitted onto the other end of the rotating shaft.

[0017] Furthermore, the transmission component includes a second mating block, and a connecting plate is fixedly connected to the outer surface of the weighing tube, with the second mating block fixedly connected to the end of the connecting plate;

[0018] Each of the slide rods is fixedly connected to a first mating block at one end extending outside the sleeve, and each first mating block abuts against and slides with a second mating block;

[0019] Each first mating block is fixedly connected to the outer surface of the sleeve with a spring, and the spring is sleeved on the corresponding slide rod.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. When discharging the raw material from the weighing tube, starting the motor drives the connecting rod, the first bevel gear, and the spur gear to rotate. The first bevel gear drives the second bevel gear to rotate, causing the rotating shaft and the placement plate to rotate. The placement plate tilts during rotation, causing the raw material to fall downwards. At the same time, the spur gear drives the gear ring to rotate, causing the scraper to slide on the inner wall of the weighing tube. The scraper removes the raw material adhering to the inner wall of the weighing tube, so as to discharge more raw material and reduce raw material residue.

[0022] 2. When the shelf rotates, it will drive the sleeve, sliding rod, striking block, and first mating block to rotate. When one of the first mating blocks rotates to the position of the second mating block, the second mating block will squeeze the first mating block, causing the sliding rod to slide into the sleeve. The striking block will leave the inner wall of the sleeve and compress the spring. As the first mating block rotates away from the second mating block, the spring will push the first mating block away from the sleeve, causing the striking block to move towards the inner wall of the sleeve. The striking block collides with the inner wall of the sleeve and generates vibration. The vibration will be transmitted to the shelf, so that the raw materials adhering to the shelf will fall off, further reducing the raw material residue in the weighing tube and making the feeding more accurate.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] like Figures 1-6As shown, the technical solution adopted by this utility model is as follows: A raw material feeding device for the synthesis of powdered medicines includes a feeding tank 1, with a weighing tube 3 vertically sliding through the bottom surface of the feeding tank 1. A feed pipe 2 is fixedly inserted through the top surface of the feeding tank 1, and a solenoid valve 201 is installed on the feed pipe 2. The bottom end of the feed pipe 2 extends downward to the top end of the weighing tube 3, so that the feed pipe 2 can pass the raw material into the weighing tube 3 for feeding.

[0032] A window is provided on the side of the feeding tank 1, and an inspection door 101 is hinged inside the window. By opening the inspection door 101, the operator can inspect the internal structure of the feeding tank 1 and clean the interior of the feeding tank 1.

[0033] An annular electronic weighing device 5 is fixedly installed on the inner wall of the feeding tank 1. This electronic weighing device 5 is a type of electronic scale and is an existing product. Electronic weighing devices are also described in patent CN219384076U mentioned in the background art. The weighing tube 3 is located inside the electronic weighing device 5, and two support rods are symmetrically fixedly connected to the outer surface of the weighing tube 3. Both support rods are fixedly connected to the top of the electronic weighing device 5. Weighing through the symmetrical weighing tube 3 of the electronic weighing device 5 allows for more accurate feeding.

[0034] A plate 6 is rotatably mounted inside the weighing tube 3, and several scrapers 8 are slidably mounted on the inner wall of the weighing tube 3. The scrapers 8 are arranged in a circular array inside the weighing tube 3.

[0035] A toothed ring 4 is coaxially rotatably connected to the top of the weighing tube 3, and several scrapers 8 are fixedly connected to the bottom of the toothed ring 4. A positioning ring is fixedly connected to the bottom surface of the toothed ring 4, and the positioning ring is rotatably connected to the top surface of the weighing tube 3. This positioning ring can position the toothed ring 4 at the top of the weighing tube 3.

[0036] A connecting ring 19 is rotatably connected inside the weighing tube 3, and several scrapers 8 are fixedly connected to the top of the connecting ring 19. The connecting ring 19 can increase the stability of the scrapers 8. The placement plate 6 is movably disposed inside the connecting ring 19. When the placement plate 6 is rotated to a horizontal position, the placement plate 6 and the connecting ring 19 cooperate to seal the weighing tube 3, allowing the raw material to fall onto the top of the placement plate 6.

[0037] The weighing tube 3 is equipped with a drive assembly, which can drive the plate 6 to rotate in the vertical direction and drive several scrapers 8 to rotate in the horizontal direction.

[0038] The drive assembly includes a motor 9, which is fixedly connected to the outer surface of the bottom of the weighing tube 3. A connecting rod 13 is fixedly connected to the output end of the motor 9, and the connecting rod 13 is vertically arranged.

[0039] A support block 20 is fixedly connected to one side of the weighing tube 3, and the connecting rod 13 rotates through the support block 20. The support block 20 can support the connecting rod 13 to increase its stability.

[0040] A spur gear 12 is coaxially fixed to the top of the connecting rod 13, and the spur gear 12 meshes with the gear ring 4. The motor 9 drives the connecting rod 13 and the spur gear 12 to rotate, and the spur gear 12 drives the gear ring 4 to rotate, thereby causing several scrapers 8 to rotate together in the horizontal direction.

[0041] A rotating shaft 7 is rotatably inserted through the weighing tube 3. The rotating shaft 7 is horizontally arranged, and both ends of the rotating shaft 7 extend outside the weighing tube 3. A placement plate 6 is fixedly sleeved on the rotating shaft 7, and a second bevel gear 10 is coaxially fixedly connected to one end of the rotating shaft 7.

[0042] A first bevel gear 11 is fixedly sleeved on the connecting rod 13, and the first bevel gear 11 meshes with the second bevel gear 10. The connecting rod 13 drives the first bevel gear 11 to rotate, the first bevel gear 11 drives the second bevel gear 10 to rotate, the second bevel gear 10 drives the rotating shaft 7 to rotate, and the rotating shaft 7 drives the shelf 6 to rotate in the vertical direction.

[0043] A sleeve 16 is fixedly provided at the end of the shelf 6, and the sleeve 16 is fixedly sleeved on the other end of the rotating shaft 7.

[0044] Several sliding rods 21 are evenly slidably passed through the sleeve 16, and each sliding rod 21 has a striking block 17 fixedly connected to one end that extends into the sleeve 16. The cross-sectional shape of the sliding rod 21 is rectangular, so that the sliding rod 21 can only slide on the sleeve 16 and cannot rotate.

[0045] The weighing tube 3 is equipped with a transmission component. When the sleeve 16 rotates, the transmission component drives several sliding rods 21 to slide on the sleeve 16 in sequence.

[0046] The transmission component includes a second mating block 15. A connecting plate is fixedly connected to the outer surface of the weighing tube 3, and the second mating block 15 is fixedly connected to the end of the connecting plate.

[0047] Each slide rod 21 has a first mating block 18 fixedly connected to one end extending outside the sleeve 16. Each first mating block 18 abuts against and slides with a second mating block 15. Both the first mating block 18 and the second mating block 15 are trapezoidal blocks, so that the first mating block 18 and the second mating block 15 are engaged by means of inclined surfaces.

[0048] A spring 14 is fixedly connected between each first mating block 18 and the outer surface of the sleeve 16, and the spring 14 is sleeved on the corresponding slide rod 21. In the initial state, the spring 14 pushes the first mating block 18, so that the striking block 17 abuts against the inner wall of the sleeve 16.

[0049] Working principle:

[0050] In use, connect one end of the feed pipe 2 to the tank containing the raw material of butylammonium black powder, and the raw material in the tank will enter the interior of the feed pipe 2. Move the feeding tank 1 to the feed port of the butylammonium black powder synthesis tank, so that the bottom end of the weighing pipe 3 extends into the feed port and feeds the material.

[0051] Open the solenoid valve 201 to allow the raw material in the feed pipe 2 to fall into the weighing pipe 3, where it will accumulate on top of the shelf 6. The weight of the raw material falling into the weighing pipe 3 can be detected by the electronic weighing device 5. As the amount of raw material in the weighing pipe 3 increases, the weighing pipe 3 can slide downward relative to the bottom surface of the feed tank 1.

[0052] Once the appropriate weight of raw material has fallen into the weighing tube 3, the solenoid valve 201 is closed. The feed pipe 2 stops discharging. The motor 9 is started, driving the connecting rod 13 to rotate. The connecting rod 13 drives the first bevel gear 11 and the spur gear 12 to rotate. The first bevel gear 11 drives the second bevel gear 10 to rotate. The second bevel gear 10 drives the rotating shaft 7 and the placement plate 6 to rotate. The placement plate 6 rotates to an inclined state, and the raw material on the placement plate 6 falls and enters the butammonium black drug synthesis tank through the bottom end of the weighing tube 3.

[0053] The spur gear 12 drives the gear ring 4 to rotate, and the gear ring 4 drives the scraper 8 and the connecting ring 19 to rotate on the inner wall of the weighing tube 3. The scraper 8 can scrape off the raw material adhering to the inner wall of the weighing tube 3.

[0054] The rotating shaft 7 simultaneously drives the sleeve 16, slide rod 21, striking block 17, and first mating block 18 to rotate. When one of the first mating blocks 18 rotates to the position of the second mating block 15, the second mating block 15 will press against the first mating block 18. The first mating block 18 pushes the slide rod 21 to slide inward into the sleeve 16, causing the striking block 17 to move away from the inner wall of the sleeve 16 and compress the spring 14. As the first mating block 18 gradually rotates away from the second mating block 15, the spring 14 will push the first mating block 18, causing the striking block 17 to move towards the inner wall of the sleeve 16. The striking block 17 will collide with the inner wall of the sleeve 16, generating vibration, which will be transmitted to the shelf 6.

[0055] As the sleeve 16 rotates, the second mating block 15 sequentially presses the corresponding first mating block 18, causing the striking block 17 to strike the sleeve 16 one by one, so that the raw materials adhering to the shelf 6 fall off.

[0056] By combining the scraper 8 and the striking block 17, the amount of raw material residue in the weighing tube 3 can be reduced, making the feeding more accurate.

[0057] After loading, rotate the shelf 6 to a horizontal position for reuse.

[0058] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
