Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of raw drug production, and specifically relates to a feeding device for raw drug production. Background Art
[0002] Generally, raw drugs are powders or granules that are irritating to the esophagus and gastric mucosa, or have a bad taste, are volatile, are easily decomposed by saliva in the mouth, or are easily inhaled into the trachea. These drugs are filled into raw material shells, which not only protects the drug properties from being damaged, but also protects the digestive organs and respiratory tract. Removing the raw material shell may cause drug loss, drug waste, and reduced drug efficacy. The production of capsule drugs requires many steps. First, the raw drug is coarsely pulverized, and then ground into powder, which is beneficial for filling the raw drug into the raw material shell.
[0003] In the Chinese patent with the publication number CN220258273U, a feeding device for raw drug production is mentioned. The utility model includes a bottom plate. Two fixing frames are fixedly connected to the upper surface of the top of the bottom plate. The upper surface of the fixing frame is fixedly connected to the outside of the mixing cylinder. A blower is fixedly installed at one end of the mixing cylinder. A main material feeding port is arranged at the top of the mixing cylinder. An auxiliary material feeding port is arranged at the top of the mixing cylinder. One end of the mixing cylinder is connected to an operation cylinder. An inlet plate is fixedly connected inside the operation cylinder. A circular through hole is arranged at the center position of the inlet plate. A motor is fixedly installed on the upper surface of the top of the operation cylinder. The output end of the motor passes through the top of the operation cylinder and is connected to a rotating shaft. A first grinding disc is fixedly connected to the bottom of the rotating shaft.
[0004] Although this device mixes and blows the raw materials into the operation cylinder by using the blower before grinding and further mixes them under the action of the blower wind in the operation cylinder, the mixing process is greatly affected by factors such as air flow, particle size, and density of the raw materials, and it is difficult to ensure the uniformity of mixing. Especially for raw materials with large particle size differences, it may lead to uneven mixing, further resulting in uneven mixing of the ground raw drugs, and cannot guarantee the consistency of the composition and quality of the raw drugs.

[0030] The crushing mechanism 2 is installed inside the support frame 1 and is used for crushing the raw medicine.
[0031] The grinding mechanism 3 is installed at the lower end of the crushing mechanism 2 and is used for grinding the raw medicine.
[0032] The mixing mechanism 4 is installed at the lower end of the grinding mechanism 3 and is used for mixing the raw medicine powder.
[0033] The crushing mechanism 2 includes a feed hopper 21 fixedly installed inside the support frame 1, and a crushing roller 22 is rotatably installed inside the feed hopper 21.
[0034] Two driving motors 23 are relatively fixedly installed on one side of the feed hopper 21, and the output end of the driving motor 23 is fixedly connected to the crushing roller 22 through a coupling.
[0035] As can be seen from the above, during use, the main material and auxiliary material of the raw medicine are first put into the upper end of the feed hopper 21 by personnel, the driving motor 23 is started through the PLC controller to drive the crushing roller 22 to rotate, and the two crushing rollers 22 rotate to generate a shearing force to crush the raw material. By crushing the raw material into small particles and then grinding, the grinding efficiency can be improved, and the feeding efficiency of the raw medicine can be further improved. The small-particle raw material can be more evenly distributed in the grinding mechanism 3, which helps to avoid problems such as uneven grinding or blockage, improve the quality of grinding the raw material, and then enter the grinding mechanism 3 for grinding and then enter the mixing mechanism 4 for full mixing.
[0036] Embodiment 2: This is the second embodiment of the present invention, including a grinding mechanism 3 installed at the lower end of the crushing mechanism 2 and used for grinding the raw medicine.
[0037] The mixing mechanism 4 is installed at the lower end of the grinding mechanism 3 and is used for mixing the raw medicine powder.
[0038] The grinding mechanism 3 includes a grinding barrel 31 fixedly connected to the lower end of the feed hopper 21, and a blanking plate 32 is fixedly installed at the lower end of the grinding barrel 31.
[0039] A rotating motor 33 is fixedly installed inside the blanking plate 32, a rotating shaft 34 is rotatably installed at the upper end of the blanking plate 32, the output end of the rotating motor 33 is fixedly connected to the rotating shaft 34 through a coupling, a plurality of grinding discs 35 are evenly fixedly installed on the outer surface of the rotating shaft 34, a plurality of grinding balls 36 are evenly fixedly installed on the upper ends of the grinding discs 35, and a plurality of grinding balls 36 are all rotatably connected to the inner wall of the grinding barrel 31. A material distribution plate 37 is fixedly installed on the outer surface of the rotating shaft 34.
[0040] As can be seen from the above, the small particle raw materials broken by the crushing mechanism 2 enter the interior of the grinding barrel 31. The rotation motor 33 is started through the PLC controller to rotate, thereby driving the rotation shaft 34 to rotate, further causing the grinding disc 35, the grinding balls 36 and the material distribution disc 37 to rotate.

By arranging multiple layers of grinding discs 35 and grinding balls 36, the raw materials can be ground multiple times, improving the fineness of particle grinding. The ground particles enter the mixing mechanism 4 through the blanking disc 32, and the mixing mechanism 4 fully mixes the multiple ground raw materials.
[0041] Embodiment 3: This is the third embodiment of the present invention, including a mixing mechanism 4, which is installed at the lower end of the grinding mechanism 3 and is used for mixing the raw material powder of the medicine.

[0045] As can be seen from the above, during use, the insertion plate 45 is inserted into the threaded connection slot 44, and the corrugated pipe 46 is stretched, so that the inlet end of the corrugated pipe 46 is located at the lower end of the grinding barrel 31. The ground raw materials are discharged through the blanking disc 32, and the corrugated pipe 46 can prevent the ground raw materials from escaping into the air during discharging, causing waste of raw materials.
[0046] After the grinding work is completed, the operator disassembles the corrugated pipe 46, screws the sealing cover matching the mixing barrel 43 onto the outer surface of the threaded connection slot 44 to seal the mixing barrel 43. Then, the stepping motor 41 is started through the PLC controller to drive the rotating shaft 42 to rotate, thereby driving the mixing barrel 43 to rotate to fully mix the multiple ground raw material medicines. By rotating the mixing barrel 43, it can be ensured that the raw material medicines are evenly mixed during the mixing process, ensuring the consistency of the composition and quality of each mixing batch, reducing the batch-to-batch difference of the products.
