Description

Technical Field

[0001] The present invention relates to the technical field of soft capsule production, and particularly relates to an apparatus and a preparation method for preparing rubber sheets for soft capsule production. Background Art

[0002] Soft capsules, which belong to a type of packaging for capsules, are commonly used in pharmaceutical or health food capsules. They are a type of capsule dosage form in which liquids, semi-solids, liquid-solids, powders and other drugs are processed and sealed in soft capsule materials. They have the advantages of fast disintegration speed, high bioavailability, and very low content deviation. The rubber sheet of a soft capsule is mainly made of gelatin, glycerin and other pharmaceutical excipients. When producing the rubber sheet of a soft capsule, various raw materials usually need to be accurately weighed and put into a clean container, and then heated to a certain temperature to dissolve them quickly. At the same time, appropriate auxiliary materials are added to achieve the ideal concentration and consistency. After mixing evenly and removing impurities or bacteria, the glue solution is extruded through a special extrusion head or pump head to form continuous slender filaments. Then, the filaments are exposed to hot air or nitrogen flow to be quickly dried and form a solid rubber sheet.

[0003] When producing the rubber sheet of a soft capsule, if particles, precipitates or other impurities appear during the production process and the temperature is uneven during the drying process, it may affect the uniformity and stability of the colloid, resulting in uneven texture of the produced rubber sheet, and causing areas on the produced soft capsule that are prone to react with saliva. As a result, the rubber sheet becomes sticky when it encounters saliva, is not easy to swallow smoothly, and has poor comfort during taking. In order to improve the comfort of taking soft capsules, in the prior art, generally, when preparing the glue solution, excessive stirring is not carried out to reduce the generation of unnecessary particles, precipitates or foams, thereby improving the uniformity and stability of the colloid. Also, extracts of banana stems, pumpkin capsule powders, red date meat pastes, and a large proportion of sodium octenyl succinate aluminum starch are added to the raw materials in a certain proportion, so as to greatly improve the water absorption and adhesion resistance, anti-leakage, and anti-dry hardness of the capsules, be able to greatly reduce the thickness of the capsules, save more space, reduce the volume of the capsules, and do not significantly affect the disintegration time. It can also achieve the effects of anti-leakage, anti-swallowing adhesion, maintaining softness, and being more easily swallowed.

[0004] However, if the raw materials are not properly stored under the correct conditions during the process of supporting the rubber sheet, such as too high or too low temperature, or are contaminated during the addition process, it may also cause the produced soft capsules to become sticky when they encounter saliva and not be easy to swallow smoothly. At this time, the method of avoiding excessive stirring to reduce unnecessary particles, precipitates or foams generated by the raw materials is difficult to solve the problem that the produced soft capsules become sticky when they encounter saliva and are not easy to swallow smoothly. Summary of the Invention

[0005] The present invention provides a rubber sheet preparation device and a preparation method for soft capsule production, which solves the problem in the prior art that due to the contamination of raw materials during the addition process or the presence of a large number of particles, precipitates or foams in the raw materials, the texture of the produced rubber sheet is uneven, resulting in areas on the produced soft capsules that are prone to react with saliva, thus causing the soft capsules to become sticky when entering the mouth.

The driving gear drives the first sleeve shaft to rotate within the first sleeve. The rotating disk drives the housing and the outer shell to rotate through the first sleeve.

[0076] S5. Driving: The first sleeve shaft drives the first helical gear to rotate. The first helical gear drives the second helical gear to rotate. The second helical gear drives the third helical gear to rotate. At this time, the third helical gear drives the second sleeve to rotate. The first helical gear drives the second sleeve shaft to rotate. There is relative rotation between the first sleeve shaft and the second sleeve, and the rotation directions between the first sleeve and the second sleeve shaft are opposite.

[0077] S6. Stirring: At this time, with the rotation of the second sleeve and the second sleeve shaft, the corresponding stirring impellers are driven to rotate. The two stirring impellers are arranged oppositely.

[0086] The working principle and beneficial effects of the present invention are:

[0087] 1. In the present invention, as the two stirring impellers rotate in opposite directions, the raw materials are sucked into the shell from the corresponding multiple feed slots, and then the raw materials entering the shell are discharged into the position of the discharge slot. At this time, under the action of the two stirring impellers, the raw materials inside the shell are convected and then discharged from the discharge slot, thereby stirring the raw materials, improving the uniformity of stirring, and reducing the possibility of particulate inclusion, precipitation or foam in the glue after stirring. Through the setting of the scraper, while cooperating with the stirring impeller to stir the raw materials, the raw materials attached to the inner wall of the mixing drum due to viscosity are scraped off and continued to be stirred, thereby improving the uniformity and efficiency of stirring.

[0088] 2. In the present invention, the glue liquid entering the discharge barrel will flow into the transition barrel from the discharge hopper. Through the setting of the filter screen, larger particle inclusions and bubbles can be effectively filtered out to make the glue liquid more uniform. At this time, the agitator is started to stir the glue liquid entering the transition barrel, which can not only further improve the uniformity of the glue liquid, but also remove the bubbles generated in the glue liquid, so that the produced rubber skin is more uniform.

[0089] 3. In the present invention, since the discharge trough has a certain angle, the discharge end of the discharge trough is close to the position of the sliding plate. In this way, after the glue liquid enters the discharge hopper along the connecting tube and the discharge pipe, the possibility of splashing of the glue liquid can be reduced, and the bubbles that may be mixed in the glue liquid are further eliminated, and then the glue liquid can be discharged.

[0090] 4. In the present invention, the stirred glue liquid can be filtered through the cooperation of the stirring part and the filtering component, which improves the uniformity of the glue liquid, reduces the inclusion of impurities such as precipitation and bubbles in the glue liquid, and improves the quality of the produced rubber. Through the setting of the discharging component, the thickness of the rubber can be adjusted, the uniformity of the rubber is improved, and the phenomenon of bubbles included in the glue liquid during work can be reduced, thereby improving the quality of the rubber.

Detailed implementation manners

[0104] Next, in combination with the embodiments of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present invention.

[0105] Embodiment 1

[0106] As Figures 1 to 11 shown, this embodiment proposes a rubber film preparation device for soft capsule production, including a fixed frame 1, a stirring cylinder 2, a stirring assembly, a filtering and impurity removal assembly, a support frame 3, a discharging assembly, and a forming assembly. The stirring cylinder 2 is fixedly installed on the fixed frame 1, and the stirring assembly is installed in the stirring cylinder 2 for preparing raw materials. The stirring assembly includes a top shell 4, a first motor 5, a driving gear 6, a rotating disk 7, a first toothed ring 8, an intermediate gear 9, a scraping plate 10, and a stirring part. The top shell 4 is fixedly installed on the top of the stirring cylinder 2, the first motor 5 is fixedly installed on the top shell 4, the driving gear 6 is fixedly installed on the output end of the first motor 5, the rotating disk 7 is rotatably installed on the stirring cylinder 2, the first toothed ring 8 is fixedly installed on the rotating disk 7, the intermediate gear 9 is rotatably installed on the top shell 4, the intermediate gear 9 meshes with the first toothed ring 8 and the driving gear 6 respectively. A scraping plate 10 is fixedly installed on the rotating disk 7, and the scraping plate 10 is slidably matched with the inner wall of the stirring cylinder 2. The stirring part is installed on the driving gear 6 for stirring the raw materials.

[0107] Specifically, when producing the rubber film of the soft capsule, first, various raw materials are accurately weighed and poured into the stirring cylinder 2, then the heater 23 is started to heat the raw materials to a certain extent to dissolve them, and then an appropriate amount of auxiliary materials are added to the melted raw materials. At this time, the first motor 5 is started, the first motor 5 drives the driving gear 6 to rotate, the driving gear 6 drives the intermediate gear 9 to rotate, the intermediate gear 9 drives the first toothed ring 8 to rotate, so as to drive the rotating disk 7 to rotate through the first toothed ring 8, and the rotating direction of the rotating disk 7 is opposite to that of the driving gear 6. Then, the rotating disk 7 can drive the scraping plate 10 to rotate, and the driving gear 6 drives the stirring part to rotate. When stirring the raw materials and the added auxiliary materials in the stirring cylinder 2, through the setting of the scraping plate 10, while cooperating with the stirring part to stir the raw materials, the raw materials attached to the inner wall of the stirring cylinder 2 due to viscosity are scraped off and continue to be stirred, improving the uniformity and efficiency of stirring. The stirred glue solution will pass through the filtering and impurity removal assembly to filter and remove impurities from the stirred glue solution, and reduce the occurrence of bubbles or particles in the glue solution. Then, the glue solution is discharged into the discharging assembly, and the glue solution is coated on the forming assembly. After the rubber film is formed, the rubber film is sent to the next process or wound and stored.

[0108] As described above, as Figures 3 to 6As shown in the figure, the stirring part includes a first sleeve 11, a first sleeve shaft 12, a housing 13, an outer shell 14, a feed trough 15 and a discharge trough 16. The first sleeve 11 is fixedly installed on the rotating disk 7, the first sleeve shaft 12 is fixedly installed on the driving gear 6, the first sleeve shaft 12 and the first sleeve 11 are rotationally matched, the housing 13 is fixedly installed on the first sleeve 11, the outer shell 14 is fixedly installed on the housing 13, a plurality of feed troughs 15 are equiangularly arranged at the upper and lower ends of the outer shell 14, and the discharge trough 16 is fixedly installed at the middle part of the outer shell 14 at equal angles.

[0109] Specifically, when stirring the raw materials, since the driving gear 6 and the rotating disk 7 rotate in opposite directions, the driving gear 6 can drive the first sleeve shaft 12 to rotate in the first sleeve 11. Through the rotation of the rotating disk 7, the rotating disk 7 drives the first sleeve 11 to rotate, thereby driving the housing 13 and the outer shell 14 to rotate and stirring the raw materials.

[0110] As described above, as Figures 3 to 6 shown in the figure, it further includes a first helical gear 17, a second helical gear 18, a third helical gear 19, a second sleeve 20, a second sleeve shaft 21, a stirring impeller 22 and a heater 23. The first helical gear 17 is rotatably installed on the housing 13, the first helical gear 17 is fixedly connected to the first sleeve shaft 12, the second helical gear 18 is rotatably installed on the inner side wall of the housing 13, the third helical gear 19 is rotatably installed on the housing 13, the second helical gear 18 meshes with the first helical gear 17 and the third helical gear 19 respectively, the second sleeve 20 is fixedly installed on the third helical gear 19, the second sleeve shaft 21 is fixedly installed on the first helical gear 17, the second sleeve shaft 21 and the second sleeve 20 are rotationally matched, stirring impellers 22 are fixedly installed on both the second sleeve 20 and the second sleeve shaft 21, the two stirring impellers 22 are located at the upper and lower ends of the plurality of discharge troughs 16, and the heater 23 is fixedly installed on the stirring cylinder 2.

[0111] Specifically, as the first set of shafts 12 rotate in the first sleeve 11, the first set of shafts 12 drive the first helical gear 17 to rotate. The first helical gear 17 drives the second helical gear 18 to rotate, and the second helical gear 18 drives the third helical gear 19 to rotate. At this time, the third helical gear 19 drives the second sleeve 20 to rotate, and the first helical gear 17 drives the second set of shafts 21 to rotate. There is relative rotation between the first sleeve 11 and the second sleeve 20, and the rotation directions of the first sleeve 11 and the second set of shafts 21 are opposite. At this time, as the second sleeve 20 and the second set of shafts 21 rotate, the corresponding stirring impellers 22 are driven to rotate. The two stirring impellers 22 are arranged oppositely. With the reverse rotation of the two stirring impellers 22, the raw materials can be sucked into the housing 14 from the corresponding multiple feeding slots 15, and then the raw materials entering the housing 14 are all discharged to the position of the discharge slot 16. At this time, under the action of the two stirring impellers 22, the raw materials inside the housing 14 undergo convection and are then discharged from the discharge slot 16, thereby stirring the raw materials, improving the uniformity of stirring, and reducing the possibility of particulate inclusions, precipitation, or foaming in the stirred adhesive solution.

[0112] As Figure 3 , Figure 4 and Figure 7 As shown in

[0113] Specifically, after the adhesive solution is prepared, it needs to be discharged. At this time, the valve 25 is started, and the adhesive solution can enter the discharge cylinder 24. The adhesive solution entering the discharge cylinder 24 will flow into the transition cylinder 26 from the discharge hopper 27. Through the setting of the filter screen 28, relatively large inclusions and bubbles can be effectively filtered out, making the adhesive solution more uniform. At this time, the stirrer is started to stir the adhesive solution entering the transition cylinder 26, which can not only further improve the uniformity of the adhesive solution but also remove the bubbles generated in the adhesive solution, making the produced rubber sheet more uniform.

[0114] As Figures 1 to 3 and Figure 8As shown, the supporting frame 3 is fixedly mounted on the fixed frame 1, the discharging assembly is mounted on the supporting frame 3, and is used to control the discharging of the glue liquid. The discharging assembly includes a discharging hopper 30, a connecting tube 31, a discharge trough 32, a first water pump 33, a feed pipe 34 and a discharge pipe 35. The discharging hopper 30 is fixedly mounted on the supporting frame 3, the connecting tube 31 is fixedly mounted on the discharging hopper 30, a discharge trough 32 is fixedly mounted on one side of the connecting tube 31, the first water pump 33 is fixedly mounted on the fixed frame 1, the feed pipe 34 is connected between the input end of the first water pump 33 and the discharge end of the transition tube 26, and the discharge pipe 35 is connected between the output end of the first water pump 33 and the connecting tube 31.

[0115] Specifically, after being stirred by the ultrasonic agitator 29, the first water pump 33 is started. The first water pump 33 extracts the glue liquid in the transition tube 26 through the feed pipe 34, and then discharges the glue liquid into the connecting tube 31 through the discharge pipe 35. The glue liquid entering the connecting tube 31 will enter the discharge hopper 30 through the discharge groove 32. Since the discharge groove 32 has a certain angle, the discharge end of the discharge groove 32 is close to the position of the sliding plate 36. In this way, after the glue liquid enters the discharge hopper 30 along the connecting tube 31 and the discharge pipe, the possibility of splashing of the glue liquid can be reduced, and the bubbles that may be mixed in the glue liquid are further eliminated, and then the glue liquid can be discharged.

[0116] The above, such as Figure 8 As shown, it also includes a sliding plate 36 and a first electric cylinder 37. Two sliding plates 36 are slidably installed on both sides of the inside of the discharge hopper 30, and the first electric cylinder 37 is fixedly installed on both sides of the outside of the discharge hopper 30. The two sliding plates 36 are fixedly connected to the output ends of the corresponding first electric cylinders 37.

[0117] Specifically, when discharging the glue liquid from the discharge hopper 30, it is also necessary to adjust the position of the sliding plate 36 to adjust the thickness of the manufactured rubber. First, according to the requirement of the rubber thickness, the first electric cylinders 37 on both sides of the discharge hopper 30 are started. The first electric cylinders 37 on both sides of the discharge hopper 30 respectively drive the corresponding sliding plates 36 to move electrically, thereby adjusting the size of the discharge end of the discharge hopper 30, thereby adjusting the thickness of the manufactured rubber, and then the first electric cylinders 37 are closed and locked.

[0118] like Figure 9 , Figure 11As shown in the figure, the forming assembly is installed on the discharging assembly and is used to form rubber solution into rubber sheets. The forming assembly includes a forming roller 38, a material guiding roller 39, a spiral cooling pipe 40, a second water pump 41, a liquid discharging pipe 42, a liquid inlet pipe 43, a cooler 44, a second gear ring 45, a second motor 46 and a fourth gear 47. The forming roller 38 is rotatably installed on the support frame 3. The forming roller 38 is located below the discharging end of the discharging hopper 30. The material guiding roller 39 is rotatably installed on the support frame 3. The spiral cooling pipe 40 is fixedly installed inside the forming roller 38. The second water pump 41 is fixedly installed on the support frame 3. One end of the spiral cooling pipe 40 is rotatably communicated with the liquid discharging pipe 42. The liquid discharging pipe 42 is communicated with the input end of the second water pump 41. The other end of the spiral cooling pipe 40 is rotatably communicated with the liquid inlet pipe 43. The liquid inlet pipe 43 is communicated with the output end of the second water pump 41. The cooler 44 is fixedly installed on the liquid discharging pipe 42. The second gear ring 45 is fixedly installed on the forming roller 38. The second motor 46 is fixedly installed on the support frame 3. A fourth gear 47 is fixedly installed at the output end of the second motor 46. The fourth gear 47 meshes with the second gear ring 45.

[0119] Specifically, after the rubber solution leaves the discharging hopper 30 through the two sliding plates 36 and flows onto the forming roller 38, the second motor 46 is started at this time. The second motor 46 drives the fourth gear 47 to rotate. The fourth gear 47 drives the second gear ring 45 to rotate. The second gear ring 45 can drive the forming roller 38 to rotate. At this time, the coolant in the spiral cooling pipe 40 cools the rubber solution, so that the rubber solution is formed into a rubber sheet. At this time, the second water pump 41 is started. The second water pump 41 extracts the coolant in the spiral cooling pipe 40 through the liquid discharging pipe 42, and the cooler 44 is started to cool the coolant in the liquid discharging pipe 42. Then, the cooled coolant is discharged into the spiral cooling pipe 40 through the liquid inlet pipe 43, so that the forming roller 38 always maintains a relatively low temperature. Then, the rubber solution coated on the forming roller 38 is cooled until the rubber solution is formed into a rubber sheet. Then, the rubber sheet is manually peeled off, laid on the material guiding roller 39, and then the rubber sheet is sent to the next process or the formed rubber sheet is wound up.

[0120] As described above, as Figure 10 shown in the figure, it further includes a material pushing assembly. The material pushing assembly includes a second electric cylinder 48, a mounting frame 49 and a material pushing roller 50. The second electric cylinder 48 is fixedly installed on the support frame 3. The mounting frame 49 is fixedly installed at the output end of the second electric cylinder 48. A material pushing roller 50 is rotatably installed on the mounting frame 49.

[0121] Specifically, when manufacturing the rubber sheet, start the second electric cylinder 48. The second electric cylinder 48 drives the mounting frame 49 to move, and the mounting frame 49 drives the material pushing roller 50 to move until the material pushing roller 50 contacts the formed rubber sheet. With the movement of the rubber sheet, the material pushing roller 50 will also rotate on the mounting frame 49, thereby making the thickness of the rubber sheet more uniform and improving the quality of the rubber sheet.

[0122] In summary, when manufacturing the rubber sheet of soft capsules, first accurately weigh various raw materials and pour them into the mixing cylinder 2. Then start the heater 23 to heat the raw materials to a certain extent to dissolve them. Then add appropriate auxiliary materials to the melted raw materials. At this time, start the first motor 5. The first motor 5 drives the driving gear 6 to rotate. The driving gear 6 drives the intermediate gear 9 to rotate. The intermediate gear 9 drives the first toothed ring 8 to rotate. Thus, the rotating disk 7 is driven to rotate by the first toothed ring 8, and the rotating direction of the rotating disk 7 is opposite to that of the driving gear 6. Then the scraping plate 10 can be driven to rotate by the rotating disk 7. The first sleeve shaft 12 is driven to rotate by the driving gear 6. Since the rotating directions of the driving gear 6 and the rotating disk 7 are opposite, the driving gear 6 can drive the first sleeve shaft 12 to rotate within the first sleeve 11. With the rotation of the rotating disk 7, the rotating disk 7 drives the first sleeve 11 to rotate, thereby driving the housing 13 and the outer shell 14 to rotate.

[0123] As the first sleeve shaft 12 rotates in the first sleeve 11, the first sleeve shaft 12 drives the first bevel gear 17 to rotate. The first bevel gear 17 drives the second bevel gear 18 to rotate. The second bevel gear 18 drives the third bevel gear 19 to rotate. At this time, the third bevel gear 19 drives the second sleeve 20 to rotate. The first bevel gear 17 drives the second sleeve shaft 21 to rotate. Relative rotation occurs between the first sleeve shaft 12 and the second sleeve 20, and the rotating directions of the first sleeve 11 and the second sleeve shaft 21 are opposite. At this time, with the rotation of the second sleeve 20 and the second sleeve shaft 21, the corresponding stirring impellers 22 are driven to rotate. The two stirring impellers 22 are arranged oppositely. With the reverse rotation of the two stirring impellers 22, the raw materials can be sucked into the outer shell 14 from the corresponding multiple feeding grooves 15, and then the raw materials entering the outer shell 14 are all discharged to the position of the discharge groove 16. At this time, under the action of the two stirring impellers 22, the raw materials inside the outer shell 14 undergo convection and are then discharged from the discharge groove 16, thereby stirring the raw materials, improving the uniformity of stirring, and reducing the possibility of particulate inclusions, precipitation, or foaming in the stirred glue. When stirring the raw materials and added auxiliary materials in the mixing cylinder 2, through the setting of the scraping plate 10, while cooperating with the stirring impellers 22 to stir the raw materials, the raw materials adhering to the inner wall of the mixing cylinder 2 due to viscosity are scraped off and continue to be stirred, further improving the uniformity and efficiency of stirring.

[0124] After the glue liquid is prepared, it needs to be discharged. At this time, start the valve 25 and the glue liquid can enter the discharge barrel 24. The glue liquid entering the discharge barrel 24 will flow into the transition barrel 26 from the discharge hopper 27. Through the setting of the filter screen 28, large particles and bubbles can be effectively filtered out to make the glue liquid more uniform. At this time, start the agitator to stir the glue liquid entering the transition barrel 26, which can not only further improve the uniformity of the glue liquid, but also remove the bubbles generated in the glue liquid, so that the produced rubber is more uniform.

[0125] After being stirred by the ultrasonic stirrer 29, the first water pump 33 is started. The first water pump 33 extracts the glue liquid in the transition tube 26 through the feed pipe 34, and then discharges the glue liquid into the connecting tube 31 through the discharge pipe 35. At this time, the position of the sliding plate 36 is adjusted to adjust the thickness of the rubber. First, according to the requirement of the rubber thickness, the first electric cylinders 37 on both sides of the discharge hopper 30 are started. The first electric cylinders 37 on both sides of the discharge hopper 30 respectively drive the corresponding sliding plates 36 to move electrically, thereby adjusting the thickness of the discharge hopper 30. The size of the material end can be adjusted to adjust the thickness of the manufactured rubber, and then the first electric cylinder 37 can be closed and locked. At this time, the glue liquid entering the connecting tube 31 will enter the discharge hopper 30 through the discharge groove 32. Since the discharge groove 32 has a certain angle, the discharge end of the discharge groove 32 is close to the position of the sliding plate 36. In this way, after the glue liquid enters the discharge hopper 30 along the connecting tube 31 and the discharge pipe, the possibility of splashing of the glue liquid can be reduced, and the bubbles that may be mixed in the glue liquid are further eliminated, and then the glue liquid can be discharged.

[0126] After the glue solution leaves the discharge hopper 30 through the two sliding plates 36, it flows onto the forming roller 38. At this time, the second motor 46 is started, and the second motor 46 drives the fourth gear 47 to rotate. The fourth gear 47 drives the second toothed ring 45 to rotate, and the second toothed ring 45 can drive the forming roller 38 to rotate. At this time, the coolant in the spiral cooling pipe 40 cools the glue solution, so that the glue solution is formed into rubber sheets. Then, the second electric cylinder 48 is started, and the second electric cylinder 48 drives the mounting bracket 49 to move. The mounting bracket 49 drives the pushing roller 50 to move until the pushing roller 50 contacts the formed rubber sheet. With the movement of the rubber sheet, the pushing roller 50 will also rotate on the mounting bracket 49, so that the thickness of the rubber sheet is more uniform, improving the quality of the rubber sheet. At this time, the second water pump 41 is started, and the second water pump 41 extracts the coolant in the spiral cooling pipe 40 through the drain pipe 42, and the cooler 44 is started to cool the coolant in the drain pipe 42, and then the cooled coolant is discharged into the spiral cooling pipe 40 through the inlet pipe 43, so that the forming roller 38 always maintains a low temperature, and then the glue solution coated on the forming roller 38 is cooled until the glue solution is formed into a rubber sheet. Then, the rubber sheet is manually peeled off, laid on the guiding roller 39, and then the rubber sheet is sent to the next process or the formed rubber sheet is wound up.
