[0002] Soft capsules are one of the dosage forms of health foods. Common ones include propolis, deep-sea fish oil and soy isoflavones. The production methods of soft capsule health foods are generally compression and dripping methods. The compression method is to place the drug between two rubber plates and press it with a steel mold. In the continuous production process, the production is automated and efficient, and it can be quickly formed, with little difference in the finished products.

[0003] Related patent documents disclose a capsule forming device comprising a capsule pressing device and a capsule drying device. The capsule pressing device comprises a pair of forming rollers rotating in opposite directions. The forming rollers include a central rotating shaft with a heating ring connected to the outside of the rotating shaft via a bearing. A fixing plate is disposed on the outside of the heating ring. The fixing plate and the heating ring are integrally formed. An arc-shaped fixing plate is disposed between adjacent fixing plates. A forming plate is fixed to the outside of the arc-shaped fixing plate. The rotating shaft is driven by a driving device. The outer surface of the forming plate has grooves. A liquid medicine filling device is disposed above the pair of forming rollers. Rubber sheet film-forming cylinders are also disposed on both sides of the pair of forming rollers. During use, a rubber sheet is attached to the grooves of the two forming plates, and liquid medicine is sandwiched between the two rubber sheets. The two rubber sheets are then heated and bonded together to form a capsule.

[0004] However, the capsule is easily adhered to the groove of the forming roller under the action of the forming roller and is difficult to fall off from the forming roller automatically. Utility Model Content

[0005] In order to make the capsule easily fall off the forming roller, the present application provides a rapid forming device for capsule products.

[0006] This application provides a rapid prototyping device for capsule products, which adopts the following technical solutions:

[0007] A rapid prototyping device for capsule products comprises two relatively rotating forming rollers, the outer walls of the forming rollers being formed with grooves, an air outlet hood being provided inside the forming rollers, the forming rollers comprising an outer layer, a mesh layer and an inner layer, the groove being located on the outer layer, the mesh layer being attached to the inner wall of the outer layer and forming the bottom of the groove, a plurality of through holes being provided on the inner layer, each through hole being connected to a groove through the mesh layer; a fixed shaft being provided inside the forming rollers, the forming rollers being rotatably connected to the fixed shaft, the air outlet hood being fixed on the fixed shaft and being located below the forming rollers, the opening of the air outlet hood being downwardly connected to the groove through the through holes, and an air pump for supplying air into the air outlet hood being connected to the air outlet hood.

[0008] By adopting the above technical solution, when in use, the two forming rollers rotate relative to each other, and the grooves on the two forming rollers are used to form capsules. When the capsules move with the forming rollers and stick to the grooves, the grooves rotate to the bottom of the air outlet hood. Due to the outer layer, mesh layer and inner layer structure adopted by the forming rollers, the grooves on the outer layer are connected to the air outlet hood through the mesh layer and the through holes, so that the pressurized gas generated by the air pump in the air outlet hood is blown into the grooves, so that the capsules in the grooves are blown out of the grooves, so that the capsules can be easily fallen off from the forming rollers.

[0009] Preferably, a brush roller is provided outside the forming roller, and the outer wall of the brush roller moves relative to the outer wall of the forming roller, and the outer wall of the brush roller is arranged close to the outer wall of the forming roller.

[0010] Preferably, two brush rollers are provided on the outside of the same forming roller, and a transmission gear is provided on the same end of the two brush rollers, and the transmission gears on the two brush rollers are meshed.

[0011] Preferably, support plates are provided at both ends of the forming roller, the support plates are rotatably connected to the fixed shaft through bearings, an inner edge is provided on the inner wall of the inner layer, and the support plates and the inner edge are fixed by connecting bolts.

[0012] Preferably, a driving gear is coaxially fixed on one end of the forming roller, the driving gear is connected to a driving gear, the driving gear is connected to a driving motor for driving the driving gear to rotate, the driving gear is engaged with the driving gear, each of the two forming rollers is engaged with a driving gear and the two driving gears are connected to the driving gears and are engaged with each other.

[0013] Preferably, a driven gear is coaxially fixedly provided on one end of the brush roller, and the driving gear is meshed with the driven gear.

[0014] Preferably, an air suction hood is provided inside the forming roller, the air suction hood faces obliquely upwards where the two forming rollers cooperate with each other, and the air suction hood is connected to a vacuum pump.

[0015] Preferably, connecting screws are provided on the inner walls of both ends of the forming roller, the connecting screws pass through the inner layer and the mesh layer, and the connecting screws are threadedly connected to the outer layer.

[0016] In summary, this application also has at least one of the following beneficial technical effects:

[0017] 1. Since there is also a suction hood inside the forming roller, the vacuum pump connected to the suction hood makes the rubber sheet in the groove stick to the inner wall of the groove, so that the shape of the formed capsule is relatively stable, reducing the difference in the finished product;

[0018] 2. A brush roller is installed under the forming roller. Since the brush roller contacts the outer wall of the forming roller, when the tape is blown by the pressurized gas in the groove, the brush roller moves the capsule, thereby accurately peeling the capsule from the groove.

[0019] 3. Each forming roller is connected to a driving gear, and each driving gear is connected to an active gear. The two active gears are also meshed with each other. Therefore, driven by the driving motor, the two active gears can keep the two forming rollers in the same rotation speed and maintain the accurate relative position;

[0020] 4. The forming roller consists of an outer layer, a mesh layer and an inner layer. The mesh layer has a small hole structure that can be connected to the through holes and grooves, reducing excessive deformation of the rubber sheet in the grooves and facilitating the production of the forming roller.

[0021] 5. Support plates are set at both ends of the forming roller, which are rotatably connected to the fixed shaft through the support plates and bearings, making the installation of the forming roller more convenient, and the air outlet cover and the air suction cover can be fixed on the fixed shaft inside the forming roller.

[0027] The following is combined with Figure 1-4 This application is described in further detail.

[0028] The present application embodiment discloses a rapid prototyping device for capsule products, referring to Figure 1 and Figure 2, including two forming rollers 1, the two forming rollers 1 are arranged opposite to each other, and the outer surfaces of the two forming rollers 1 are provided with grooves 2. The two forming rollers 1 rotate at the same speed relative to each other so that the grooves 2 on the two forming rollers 1 can face each other. When the two rubber sheets are squeezed between the two forming rollers 1, a capsule is formed at the position of the two grooves 2, and then continues to rotate downward. Due to the viscosity of the capsule, it may stick to any one of the two forming rollers 1. A brush roller 3 is provided below the forming roller 1. Both ends of the brush roller 3 are rotatably connected to the frame 5. The brush roller 3 is arranged parallel to the forming roller 1, and the brush roller 3 contacts the side wall of the forming roller 1, so that the brush roller 3 can clean the surface of the forming roller 1. When a capsule sticks to the groove 2 of the forming roller 1, the brush roller 3 can move the capsule from the groove 2.

[0029] A fixed shaft 4 is provided inside the forming roller 1, and bearings 41 are provided on the fixed shaft 4. Both ends of the fixed shaft 4 are fixed to the frame 5. The forming roller 1 is rotatably connected to the fixed shaft 4 through the bearings 41. An air suction hood 6 and an air outlet hood 7 are provided inside the forming roller 1. The air suction hood 6 and the air outlet hood 7 are both fixedly connected to the fixed shaft 4. The opening of the air suction hood 6 faces obliquely upward from the mating position of the two forming rollers 1 and is close to the inner wall of the forming roller 1. The opening of the air outlet hood 7 faces vertically downward and is close to the inner wall of the forming roller 1. An air outlet pipe 61 is connected to the air suction hood 6, and an air inlet pipe 71 is connected to the air outlet hood 7. Multiple air inlet pipes 71 are arranged along the axial direction of the fixed shaft 4 so that the air inlet pipe 71 can evenly distribute the air pressure to the air outlet hood 7. At the same time, the air outlet hood 7 is arranged along the axial direction of the forming roller 1 and the distributed length covers multiple grooves 2 along the axial direction of the forming roller 1. The air inlet pipe 71 extends along the fixed shaft 4 away from one end of the air outlet hood 7 and is connected to the air pump 72, which supplies pressurized gas to one end of the air outlet hood 7; the air outlet pipe 61 extends along the fixed shaft 4 away from one end of the suction hood 6 and is connected to the vacuum pump 62. The vacuum pump 62 is used to suck air from the position of the suction hood 6 to maintain a low pressure inside the suction hood 6. When the groove 2 on the forming roller 1 rotates to the position of the suction hood 6, the groove 2 is connected to the suction hood 6; when the groove 2 on the forming roller 1 rotates to directly below the air outlet hood 7, the groove 2 is connected to the air outlet hood 7; since the interior of the suction hood 6 is under negative pressure, the rubber sheet can be more easily deformed and enter the groove 2; when the capsule is completed, the capsule rotates to the bottom of the air outlet hood 7 with the forming roller 1, and the pressurized gas in the air outlet hood 7 will blow away the side of the capsule that is bonded to the groove 2, and then cooperate with the brush roller 3 to accurately separate the capsule from the forming roller 1.

[0030] The forming roller 1 includes an outer layer 11, a mesh layer 12, and an inner layer 13. The outer layer 11, mesh layer 12, and inner layer 13 are arranged in sequence from the outside inward. A groove 2 is provided in the outer layer 11, and the bottom of the groove 2 is arranged to penetrate. The mesh layer 12 is located on the inner wall of the outer layer 11, so that the mesh layer 12 blocks the position of the groove 2 and forms the bottom of the groove 2. At the same time, a plurality of through holes 14 are provided in the inner layer 13. The inner layer 13 is attached to the inner wall of the mesh layer 12 and cooperates with the outer layer 11 to clamp the mesh layer 12. A through hole 14 is provided at the bottom of each groove 2, and the through holes 14 are used to connect the air outlet hood 7 and the air intake hood 6. Because the mesh layer 12 has a mesh structure, the rubber sheet in the groove 2 is supported on the mesh layer 12 without causing excessive deformation. The small hole structure of the mesh layer 12 is utilized to reduce the manufacturing difficulties caused by opening a large number of small holes at the bottom of the groove 2.

[0031] refer to Figure 3 The forming roller 1 is provided with support plates 42 at both ends. The support plates 42 are rotatably connected to the fixed shaft 4 through bearings 41. An inner edge 131 is formed on the inner wall of the inner layer 13. The inner edge 131 is parallel to the support plate 42. Connecting bolts 43 are provided through the support plate 42. The connecting bolts 43 are threadedly connected to the inner edge 131, so that the forming roller 1 can be rotatably connected to the fixed shaft 4 through the support plates 42. A plurality of connecting screws 15 are provided on the inner walls at both ends of the forming roller 1. The connecting screws 15 penetrate the inner layer 13 and the mesh layer 12 and are threadedly connected to the outer layer 11, so that the connecting screws 15 fix the outer layer 11, the mesh layer 12 and the inner layer 13 together.

[0032] refer to Figure 4 A driving gear 81 is coaxially fixedly provided on the surface of a support plate 42 and the forming roller 1. The driving gear 81 is meshed with a driving gear 82. The driving gear 82 is connected to a driving motor 9. The driving motor 9 is fixed on the frame 5. The output shaft of the driving motor 9 is coaxially fixedly connected to the driving gear 82. The diameter of the driving gear 82 is smaller than the diameter of the driving gear 81. The driving gears 81 connected to the two forming rollers 1 are each connected to a driving gear 82. The two driving gears 82 are meshed with each other. One driving motor 9 can simultaneously drive the two driving gears 82 to rotate relative to each other. At the same time, the two driving gears 82 drive the two forming rollers 1 to rotate in opposite directions. Due to the setting of the driving gear 81 and the driving gear 82, the two forming rollers 1 maintain an accurate positional relationship.

[0033] The driven gear 83 is also meshed with the driving gear 81, and the driven gear 83 is coaxially fixed on the brush roller 3, so that the brush roller 3 is driven to rotate when the driving gear 81 rotates, and the number of teeth of the driving gear 81 is greater than the number of teeth of the brush roller 3. The meshing position of the driving gear 81 and the brush roller 3 deviates from the fitting position of the brush roller 3 and the forming roller 1, so that the rotation linear speeds of the brush roller 3 and the outer wall of the forming roller 1 are different, so that the brush roller 3 can clean the outer wall of the forming roller 1; two brush rollers 3 are arranged at the lower part of the same forming roller 1, and a transmission gear 84 is provided at the same end of the two brush rollers 3. The transmission gears 84 on the two brush rollers 3 are externally meshed with each other, so that the rotation directions of the two brush rollers 3 are opposite, and the two sides of the capsule are respectively moved, so that after any side of the capsule is blown open, it can be easily peeled off by the two brush rollers 3.

[0034] The working process of this embodiment:

[0035] When the groove 2 on the forming roller 1 rotates to the position corresponding to the air suction hood 6, the rubber sheet is deformed into the groove 2 by the negative pressure, and then the capsule is formed and sticks to the groove 2. As the forming roller 1 rotates to the bottom of the air outlet hood 7, the air pressure in the air outlet hood 7 causes the capsule to separate from the groove 2 or move. Then, when it continues to rotate to the position of the two brush rollers 3, the brush rollers 3 can peel off the capsule movably connected in the groove 2.

[0036] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
