Description

Technical Field

[0001] This utility model belongs to the field of raw material processing technology for pill production, and in particular relates to a raw material mixing device for pill production. Background Technology

[0002] Pills, such as traditional Chinese medicine pills, contain various medicinal plant tissues. After the medicinal plants are pulverized, the dry powder needs to be mixed. After the mixing process, the drug components are evenly mixed to obtain a mixed powder (dry mixing process). The mixed powder is processed into a paste with a certain viscosity by adding solvent (wet mixing process). After the paste is repeatedly mixed, it is finally fed into a pill-making device to be processed into pills. The pills are then processed into finished medicine pills.

[0003] During the mixing process, especially in the later stages when solvent is added, the viscosity of the material increases, making mixing extremely difficult. The uniformity of the paste mixture is crucial to the quality of the final pill product. Current mixing equipment uses a mixing chamber with a rotating shaft connected within it. Mixing rods are welded to the rotating shaft. During mixing, gaps exist between the mixing rods, especially as the material's viscosity increases, making it impossible for the mixing shaft and rods to fully and evenly mix the paste.

[0004] The reason is that the stirring structure cannot mix the materials back and forth by pushing them. Materials with high viscosity can only be tumbled by the stirring structure and cannot move horizontally in the chamber, which leads to insufficient uniformity of the paste mixture.

[0005] Meanwhile, in the initial stage of mixing, due to the high dryness of the powder being added to the silo for dry mixing, a large amount of dust escapes from the inlet of the silo during the mixing process, resulting in serious dust emission in the mixing workshop.

[0006] Therefore, the subsequent cleaning of the workshop is very complicated, and the dust emission poses a serious threat to the health of the operators. Utility Model Content

[0007] Based on the above background, the purpose of this utility model is to provide a mixing device for raw materials in pill production.

[0008] To achieve the above objectives, the present invention adopts the following technical solution:

[0009] A raw material mixing device for pill production includes a mixing bin, and a mixing and pushing mechanism is assembled and connected inside the mixing bin. The mixing and pushing mechanism includes a plurality of mixing shafts rotatably connected to the mixing bin, and a plurality of staggered mixing structures are installed on each mixing shaft.

[0010] The mixing structure includes a bracket fixedly connected to the mixing shaft, and a mixing frame is detachably installed on the bracket. The mixing frame includes a curved support part, and a number of toothed structures are integrally formed on the curved support part.

[0011] The mixing and pushing mechanism also includes a drive structure that drives the mixing shaft to rotate;

[0014] The upper dust cover can be detachably installed on the upper dust cover.

[0015] Preferably, the mixing and pushing mechanism includes a first mixing shaft and a second mixing shaft;

[0016] The first mixing shaft and the second mixing shaft are respectively fixedly connected to the two ends of the first rotating shaft and the second rotating shaft, and bearings that rotatably connect the first rotating shaft and the second rotating shaft are installed on the side walls on both sides of the silo body.

[0017] The mixing structures on the first mixing shaft and the second mixing shaft are staggered.

[0018] Preferably, the drive structure includes a first gear fixedly mounted on a first mixing shaft on one side, and a second gear fixedly mounted on a second mixing shaft on one side;

[0019] The first gear meshes with the second gear. A driven pulley is fixedly mounted on the first gear. The gear also includes a pulley motor. A driving pulley is fixedly mounted on the output shaft of the pulley motor and is connected to the driven pulley via a transmission belt.

[0020] Preferably, the bracket has an installation groove, and the curved bracket part is integrally formed with a rectangular bracket part, which is fastened in the installation groove by a number of mounting screws;

[0021] The toothed structure includes curved walls distributed on the curved support portion.

[0022] Preferably, the upper dust cover is provided with a discharge port, and a conical guide shroud is fixedly connected to the discharge port;

[0023] The dust extraction hood structure covers the upper part of the dust extraction hood structure.

[0024] Preferably, the dust extraction hood structure includes an exhaust hood, the exhaust end of which is connected to a spring hose, which is connected to an external exhaust pipe.

[0025] Preferably, one end of the exhaust hood is hinged to a mounting bracket, which is fixedly installed on the upper dust cover;

[0027] Preferably, the bottom of the hopper is connected to a discharge pipe, and a discharge valve plate is slidably connected to the discharge pipe.

[0028] Preferably, a steel frame supporting the silo body is fixedly connected to the bottom of the silo body.

[0029] This utility model has the following beneficial effects:

[0030] 1. The purpose of rotating a first mixing shaft and a second mixing shaft in opposite directions is as follows: During the mixing process of the first mixing shaft, the material is pushed to one side in conjunction with the mixing structure, while the other second mixing shaft, which rotates in the opposite direction, pushes the material in the opposite direction in conjunction with the mixing structure. This method achieves horizontal mixing of the material in the bin, and ensures thorough mixing of the material. The material can not only be tumbled and mixed, but also pushed and mixed horizontally.

[0031] 2. In the structural design of the mixing rack, because the curved support part (shaped like a fan) has several toothed structures integrally formed, during the mixing process, it can fully refine the materials, especially the materials in the paste, such as the encapsulated particles (lumpy, incompletely dispersed matter) in the paste.

The extraction hood is flip-up, facilitating full exposure of the conical guide hood position during material feeding. Attached Figure Description

[0046] Example 1

[0047] like Figure 1-7 As shown, a raw material mixing device for pill production includes a mixing chamber 1. The structure of the mixing chamber 1 is as follows: the mixing chamber 1 includes a chamber body 12 with a rectangular cross-sectional shape, and the top of the chamber body 12 is integrally formed with a conical chamber part 11 with an increased opening.

[0048] Meanwhile, a mixing and pushing mechanism 5 is assembled and connected inside the mixing hopper 1. The mixing and pushing mechanism 5 includes a pair of mixing shafts that are spaced apart and rotatably connected to the mixing hopper 1. The rotatable connection method is a conventional method disclosed in the prior art. Specifically, the mixing and pushing mechanism 5 includes a first mixing shaft 51 and a second mixing shaft 52. The two ends of the first mixing shaft 51 and the second mixing shaft 52 are respectively fixedly connected to a first rotating shaft and a second rotating shaft. Bearings that rotatably connect the first rotating shaft and the second rotating shaft are installed on the side walls on both sides of the hopper body 12.

[0049] Meanwhile, several staggered mixing structures 56 are installed on both the first mixing shaft 51 and the second mixing shaft 52.

[0050] The mixing structure 56 includes a bracket 561 fixedly connected to the mixing shaft (the inner end of the bracket 561 is an arc-shaped opening that matches the shaft structure and is welded and fixed to the first mixing shaft 51 and the second mixing shaft 52), and a mixing rack is detachably installed on the bracket 561.

[0051] Specifically, the mixing rack includes a curved support section 5621, on which several toothed structures 56211 are integrally formed.

[0052] Specifically, the bracket 561 has a mounting groove, and the curved bracket part 5621 is integrally formed with a rectangular bracket part 561, which is fastened to the mounting groove by a number of mounting screws. The toothed structure is distributed on the curved wall of the curved bracket part 5621.

[0053] The aforementioned mixing and pushing mechanism 5 also includes a drive structure for driving the mixing shaft to rotate; the drive structure adopts a gear transmission structure.

[0054] The advantage of the gear transmission structure is that during the gear transmission process, if the first mixing shaft 51 moves clockwise, the corresponding second mixing shaft 52 will rotate in the opposite direction, such as counterclockwise.

[0055] The purpose of the first mixing shaft 51 and the second mixing shaft 52 rotating in opposite directions is as follows: during the mixing process of the first mixing shaft 51, the mixing structure 56 pushes the material to one side, while the other second mixing shaft 52, which rotates in the opposite direction, pushes the material in the opposite direction in conjunction with the mixing structure 56. In this way, the material in the bin is horizontally pushed and mixed.

[0056] Specifically, the mixing structures 56 are staggered on the first mixing shaft 51 and the second mixing shaft 52. Specifically, the mixing structures 56 on the first mixing shaft 51 are arranged along the length direction, while the mixing structures 56 are staggered in the circumferential direction. Similarly, the mixing structures 56 on the second mixing shaft 52 are staggered in the same way.

[0057] All the mixing structures 56 on the second mixing shaft 52 are offset from the mixing structures 56 on the first mixing shaft 51 in terms of horizontal projection position (i.e., the mixing structures 56 on the first mixing shaft 51 and the mixing structures 56 on the second mixing shaft 52 are offset). That is, the mixing structures 56 on the first mixing shaft 51 extend into the gaps between the mixing structures 56 on the second mixing shaft 52.

[0058] During the rotation process, the mixing structure 56 on the first mixing shaft 51 is staggered, and a spiral driving force is generated during the rotation. Similarly, the mixing structure 56 on the second mixing shaft 52 generates a spiral driving force. Since the first mixing shaft 51 and the second mixing shaft 52 rotate in opposite directions, the materials in the bin are pushed and pulled to achieve thorough mixing.

[0059] Especially during the subsequent wet mixing process with added solvents, pastes with high viscosity can be fully mixed in this way.

[0060] Meanwhile, in the above structure, because the curved support part 5621 (shaped like a fan) has several toothed structures integrally formed, during the mixing process, it can fully refine the materials, especially the materials in the paste, such as the encapsulated particles (lumpy, incompletely dispersed matter) in the paste.

[0061] Example 2

[0062] like Figure 1-6As shown, this embodiment, based on the structure of embodiment 1, specifically discloses the detailed structure of the drive structure. The drive structure includes a first gear 53 fixedly mounted on a first mixing shaft 51 on one side, and a second gear fixedly mounted on a second mixing shaft 52 on one side. The first gear 53 meshes with the second gear, and a driven pulley 55 is fixedly mounted on the first gear. It also includes a pulley motor 54, and a driving pulley 541, which is connected to the driven pulley via a transmission belt, is fixedly mounted on the output shaft of the pulley motor 54.

[0063] The above-mentioned transmission structure enables the first mixing shaft 51 and the second mixing shaft 52 to rotate.

[0064] The above-mentioned transmission structure is a conventional transmission structure disclosed in the prior art.

[0065] Example 3

[0066] like Figure 1-6 As shown, in this embodiment, based on the structure of embodiment 2, the top of the mixing hopper 1 is detachably connected to an upper dust cover 13 (specifically, several screws are fixedly installed on the top of the mixing hopper 1, the screws pass through the upper dust cover 13 and are tightened with upper nuts). At the same time, in order to facilitate material feeding, the upper dust cover 13 is provided with a discharge port, and a conical guide shroud 131 is fixedly connected to the discharge port.

[0067] The material is added through a conical guide shroud 131. This structure effectively reduces dust generated during material feeding and mixing in the dry mixing process.

[0068] Meanwhile, a flip-open dust extraction hood structure is installed on the top of the upper dust cover 13. The dust extraction hood structure covers the upper part of the dust extraction hood structure. Further dust extraction is achieved through the dust extraction hood structure.

[0069] The aforementioned dust extraction hood structure includes an extraction hood 3, the air outlet of which is connected to a flexible spring hose 31. In existing methods, the flexible spring hose 31 is connected to an external exhaust pipe (the installation method is the same as in the prior art, via a flange connection). Specifically, by utilizing the flexibility of the flexible spring hose 31, the extraction hood 3 can be flipped, facilitating full exposure of the conical guide hood 131 during material feeding.

[0070] The above-mentioned exhaust hood 3-spring hose 31-external exhaust pipe is a conventional exhaust and dust removal method disclosed in the prior art. If a fan, such as an axial flow fan, is installed at the air outlet end of the external exhaust pipe, exhaust and dust removal can be achieved.

[0071] The front and rear side walls of the left end of the above-mentioned exhaust hood 3 are hinged with mounting brackets 21 (L-shaped, hinged by a pin), and the mounting brackets 21 are fixedly installed on the upper dust cover 13.

[0072] Meanwhile, the other end of the exhaust hood 3 has an electric push rod 2, which is hinged to the upper dust cover 13. Specifically, the pushing end of the electric push rod 2 is fixedly connected to the upper hinge sleeve, and is hinged to the exhaust hood 3 via a pin.

[0073] The bottom of the electric push rod 2 is fixedly connected to a hinge ear, which is hinged to the hinge seat fixed on the upper dust cover 13 by a pin.

[0074] Under normal circumstances, the exhaust hood 3 exhausts and discharges materials. When material needs to be added, the exhaust hood 3 is flipped under the push of the electric push rod 2.

[0075] The use of a pair of electric push rods 2 to drive the exhaust hood 3 is a conventional flipping method disclosed in the prior art. For example, the electric push rods 2 are conventional electric telescopic rods with a pushing force of 20-30 kg disclosed in the prior art. The synchronous operation of the pair of electric push rods 2 is also a conventional method disclosed in the prior art. For example, the electric push rods 2 are connected in series to the power supply, and synchronous operation is achieved by turning on the main switch of the power supply and simultaneously energizing them.

[0076] The bottom of the aforementioned hopper 12 is connected to a discharge pipe 121 (rectangular in shape). According to the existing discharge method, a discharge valve plate 1211 is slidably connected to the discharge pipe 121. Under normal circumstances, the discharge valve plate 1211 blocks the cavity of the discharge pipe 121. When discharge is required, the discharge valve plate 1211 is pulled out to discharge the material.

[0077] During the discharge process, the viscous paste flows down the discharge pipe 121. Due to its viscosity, the paste is easily discharged. In actual operation, the first mixing shaft 51 and the second mixing shaft 52 can further assist in discharging the paste (discharging is even easier while the paste is in motion).

[0078] Meanwhile, in the existing manner, a steel frame 4 supporting the storage compartment 12 is fixedly connected to the bottom of the storage compartment 12. The steel frame 4 serves as a support frame supporting the bottom of the entire device.

[0079] Of course, the above description is not intended to limit the present utility model, and the present utility model is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present utility model should also fall within the protection scope of the present utility model.
