Description

Technical Field

[0001] This utility model belongs to the field of solid dosage form granulation, and specifically relates to a solid dosage form granulation and forming machine. Background Technology

[0002] When solid dosage forms are formed, the solid dosage form powder needs to be poured into a mold and then pressed into shape using a powder tableting machine. The characteristics of powder pressing are: high pressure and slow speed are required to facilitate the expulsion of gas between powder molecules and overall shaping. Existing tableting machines are divided into high-pressure tableting machines and low-pressure tableting machines according to the pressure.

[0003] According to Chinese Patent No. CN214386026U, a calcium tablet granulation and molding machine is disclosed. This utility model relates to the technical field of calcium tablet molding machines. The calcium tablet granulation and molding machine includes a base, a housing fixedly connected to the upper surface of the base, a lifting structure on the upper part of the base, a slide rail fixedly connected to the upper surface of the base, a slider slidably connected to the upper surface of the slide rail, a storage box fixedly connected to the upper surface of the slider, a rotating device on one side of the middle of the upper surface of the base, a molding die on the upper part of the storage box, an electric rod on the middle of the rear end face of the housing, a feeding plate fixedly connected to the output end of the electric rod, a molding die on the upper part of the base near the feeding plate, an extrusion device on the upper part of the molding die, and fixed frames symmetrically arranged on the middle of the upper surface of the inner cavity of the housing. This solves the problems of inconvenient pressure control, excessive powder accumulation reducing service life, inconvenient movement, and inconvenient drug removal in existing calcium tablet granulation and molding machines.

[0004] As can be seen from the above structure, although the stamping method can achieve an effective granulation effect, the efficiency of granulation by stamping is low. After one set of granulation is completed, it is necessary to wait for feeding and refeeding before a second granulation can be carried out, which leads to a reduction in granulation effect. Therefore, a granulation and molding machine with continuous granulation is proposed to solve the problem of low granulation efficiency. Utility Model Content

[0005] In view of the problems mentioned in the background art, the purpose of this utility model is to provide a solid dosage form granulation machine to solve the problems mentioned in the background art.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0007] A solid dosage form granulation machine includes a base plate, a granulation assembly fixedly connected to the upper end of the base plate, the granulation assembly including a granulation box disposed on the upper end of the base plate, granulation rollers rotatably connected to both sides of the inner side of the granulation box, the outer surface of each granulation roller having multiple granulation grooves, a drive motor fixedly connected to one side of the granulation box, the output shaft of the drive motor passing through the granulation box and fixedly connected to the granulation rollers, a transmission gear fixedly connected to the other end of each granulation roller passing through the granulation box, the transmission gears meshing with each other, and a feeding plate fixedly connected to one side of the lower end of the granulation box.

[0008] As a preferred technical solution, the upper end of the granulation box is provided with a feeding port, the inside of the feeding port is fixedly connected to a feeding channel, the upper end of the feeding channel is fixedly connected to a feeding bin, and the inside of the feeding channel is provided with a feeding component.

[0009] As a preferred technical solution, the feeding assembly includes a rotating shaft rotatably connected inside the feeding channel. Each outer surface of the rotating shaft is fixedly connected to a material distribution plate, and multiple material distribution plates are provided. A feeding motor is fixedly connected to the outside of the feeding channel, and the output shaft of the feeding motor is fixedly connected to the rotating shaft.

[0010] As a preferred technical solution, each of the upper corners of the base plate is fixedly connected with a fixing through hole, and a fixing screw is inserted into the fixing through hole. The fixing screw passes through the fixing through hole and is threadedly connected to the base layer.

[0011] As a preferred technical solution, the feeding plate includes a frame disposed at the lower end of the granulation box, a powder plate is fixedly connected to the inner side of the frame, and a filter screen plate is fixedly connected to the inner side of the frame directly above the powder plate.

[0012] As a preferred technical solution, the upper end of the base plate is movably connected to a first collection box and a second collection box, the first collection box being located directly below the powder plate and the second collection box being located directly below the filter screen plate.

[0013] As a preferred technical solution, a support frame is fixedly connected to both sides of the upper end of the base plate, the other end of the support frame is fixedly connected to the granulation component, and a movable handle is fixedly connected to the outer side of the support frame.

[0014] In summary, the present invention has the following main advantages:

[0015] First, the granulation component of this utility model first controls the drive motor to start and drive the granulation roller to rotate. Under the action of the transmission gear, the rotation of the granulation roller can drive multiple granulation rollers to rotate relative to each other. When the granulation roller rotates, powder is added into the granulation box through the feeding channel. Then, under the rotation of multiple granulation rollers, the powder is extruded and shaped inside the granulation tank. Thus, the relative rotation of multiple granulation rollers realizes a continuous extrusion and shaping process, which gets rid of the limitation of intermittent operation, effectively increases granulation efficiency, and can better meet the output requirements of industrial production.

[0016] Secondly, this utility model, through its feeding assembly, allows powder to be added into the feeding hopper and then fed through the feeding channel. During feeding, the feeding motor is started to drive the rotating shaft, which in turn drives multiple distribution plates to rotate. This rotation of the distribution plates prevents powder from clogging inside the feeding channel, effectively solving the problem of easy clogging during powder feeding, ensuring the smoothness of the feeding process, and preventing interruptions due to blockages. This ensures a continuous supply of raw materials for subsequent granulation, and the smooth feeding maintains production continuity, reducing downtime for cleaning due to blockages, thereby improving overall production efficiency. The rotation of the distribution plates also has a certain stirring effect on the powder, making the powder more evenly distributed in the channel, which helps to evenly fill the material during subsequent granulation and improves granulation quality.

A feeding plate 11 is fixedly connected to one side of the lower end of the granulation box 21.

[0024] refer to Figure 1 , Figure 2 and Figure 4 The granulation box 21 has a feeding port 3 at its upper end. A feeding channel 4 is fixedly connected inside the feeding port 3. A feeding bin 5 is fixedly connected to the upper end of the feeding channel 4. A feeding assembly 6 is set inside the feeding channel 4. The feeding assembly 6 includes a rotating shaft 61 rotatably connected inside the feeding channel 4. A distribution plate 62 is fixedly connected to the outer surface of the rotating shaft 61. Multiple distribution plates 62 are provided. A feeding motor 63 is fixedly connected to the outer side of the feeding channel 4. The output shaft of the feeding motor 63 is fixedly connected to the rotating shaft 61. Powder is added into the feeding bin 5 and then fed through the feeding channel 4. During feeding, the feeding motor 63 is started to drive the rotating shaft 61 to rotate. The rotation of the rotating shaft 61 can drive multiple distribution plates 62 to rotate. Thus, the rotation of the distribution plates 62 can prevent the powder from clogging inside the feeding channel 4, effectively solving the problem of easy clogging during powder feeding and ensuring the smoothness of the feeding process.

[0025] refer to Figure 1 Each of the upper corners of the base plate 1 is fixedly connected with a fixing through hole 9, and a fixing screw 10 is inserted into the fixing through hole 9. The fixing screw 10 passes through the fixing through hole 9 and is threaded to the base layer. The device can be fixed by placing the device in a suitable position and then threading the fixing screw 10 through the fixing through hole 9 to the base layer.

[0026] refer to Figure 2 and Figure 3The feeding plate 11 includes a frame 111 located at the lower end of the granulation box 21. A powder plate 113 is fixedly connected to the inner side of the frame 111. A filter screen plate 112 is fixedly connected to the inner side of the frame 111 directly above the powder plate 113.

The first collection box 12 is located directly below the powder plate 113, and the second collection box 13 is located directly below the filter screen plate 112. The formed granules fall onto the surface of the feeding plate 11. Under the action of the filter screen plate 112, the granules can be filtered, and the unprocessed powder can be filtered onto the surface of the powder plate 113 for feeding, thereby achieving the effect of separate feeding during use.

[0028] Operating principle and advantages: First, by placing the device in a suitable position and threading the fixing screws 10 through the fixing through holes 9 to the base surface, the device can be fixed. After fixing, the device can be used. Powder is added into the feeding hopper 5 and then fed through the feeding channel 4. During feeding, the feeding motor 63 is started to drive the rotating shaft 61 to rotate. The rotation of the rotating shaft 61 drives multiple distributing plates 62 to rotate, thus preventing the powder from clogging inside the feeding channel 4. Then, the drive motor 24 is started to drive the granulation roller 22 to rotate. Under the rotation of the granulation roller 22, the powder is transferred to the feed channel 4. The moving gear 25 drives multiple granulation rollers 22 to rotate relative to each other. When the granulation rollers 22 rotate, powder is added into the granulation box 21 through the feeding channel 4. Then, under the rotation of multiple granulation rollers 22, the powder is extruded and shaped inside the granulation tank 23. Thus, the relative rotation of multiple granulation rollers 22 realizes a continuous extrusion and shaping process, which gets rid of the limitation of intermittent operation and effectively increases the granulation efficiency. The granulated particles fall onto the surface of the feeding plate 11. Under the action of the filter screen 112, the particles can be filtered. Unprocessed powder can be filtered onto the surface of the powder plate 113 for feeding, thus achieving the effect of separate feeding during use.
