[0045] The following will further elaborate on the present invention in conjunction with the attached Figures 1-13 drawings.

[0046] A lubricity - increasing device for axial mixing of gelatin hollow capsules, as Figures 1-13 shown, in this embodiment, it includes a frame body 1, a quantitative feeding mechanism 2, a powder micro - feeding mechanism 3, a lubricity - increasing roller mechanism 4, a discharging mechanism 5, an upper mounting plate 6, a lower mounting plate 7, and a lower mechanism mounting frame 8. The upper mounting plate 6 and the lower mounting plate 7 are respectively installed on the frame body 1, the upper mounting plate 6 is located above the lower mounting plate 7, and the lower mechanism mounting frame 8 is installed on the lower mounting plate 7.

An injection port is provided at the upper end of the roller 401, and a discharging opening is formed at the lower end. Three stirring baffles 402 are evenly arranged on the inner peripheral surface of the roller 401 to ensure the stirring and mixing effect of the capsules and the powdery materials. The roller drive assembly is used to drive the roller 401 to roll, so that the capsules and the powdery materials in the roller 401 are mixed under the action of rolling and stirring. The discharging mechanism 5 is arranged on the lower mechanism mounting frame 8, and the discharging mechanism 5 is used to control whether to discharge the capsules in the roller 401 from the discharging opening at the lower end of the roller 401.

[0048] The quantitative feeding mechanism 2 and the powder micro-feeding mechanism 3 are both located on the upper side of the lubricity increasing roller mechanism 4.

The powder micro-feeding mechanism 3 has a powder output end, and the powder output end of the powder micro-feeding mechanism 3 extends into the collecting pipe 9. The lower end of the collecting pipe 9 extends into the injection port of the roller 401. The quantitative feeding mechanism 2 is used to receive and store capsules according to a predetermined amount and to inject the capsules into the collecting pipe 9 through the capsule output end of the quantitative feeding mechanism 2. The quantitative feeding mechanism 2 is used to receive and store the powdery material required for the lubricity increasing process and to inject the powdery material into the collecting pipe 9 according to a predetermined amount. The capsules and the powdery material enter the inside of the roller 401 axially through the collecting pipe 9 to achieve sufficient stirring and mixing of the subsequent capsules and the powdery material.

[0049] Specifically, as Figures 3-5 shown, in this embodiment, the roller drive assembly includes a roller drive motor 403, a drive gear 404, a slewing bearing 405, and a roller connecting frame 406. The housing of the roller drive motor 403 is mounted on the lower mechanism mounting frame 8, and the drive shaft of the roller drive motor 403 is mounted with a drive gear 404. The slewing bearing 405 is a hollow structure and has an inner fixed ring portion 4051 and an outer rotating gear ring portion 4052. The specific structure of the slewing bearing 405 in this embodiment adopts the existing technology; the roller drive motor 403 is a commercially available product and is controlled by an external control system. The inner fixed ring portion 4051 of the slewing bearing 405 is mounted on the lower mechanism mounting frame 8, the outer rotating gear ring portion 4052 of the slewing bearing 405 is engaged with the drive gear 404, and the roller 401 passes through the inside of the inner fixed ring portion 4051 of the slewing bearing 405 and the lower mechanism mounting frame 8 respectively. The outer peripheral surface of the roller 401 is fixedly connected to the outer rotating gear ring portion 4052 of the slewing bearing 405 through the roller connecting frame 406. The roller drive motor 403 drives the drive gear 404 and then rotates the roller 401 to achieve the effect of mixing the capsules and the powdery material under the action of rolling and stirring.

[0050] Specifically, as Figures 6-8As shown in the figure, in this embodiment, the discharging mechanism 5 includes a discharging mechanism base plate 501, a cylinder A 502, a plugging plate support frame 503, a rotating plugging plate 504, and a plugging plate rotating shaft 505. The discharging mechanism base plate 501 is installed on the lower mechanism mounting frame 8. There are two symmetrically arranged cylinders A 502 on the left and right. The outer shells of each cylinder A 502 are respectively fixed to the discharging mechanism base plate 501. The telescopic directions of the driving ends of each cylinder A 502 are all parallel to the axial center line of the roller 401. The driving ends of each cylinder A 502 are all located on the side away from the upper mounting plate 6. The driving ends of each cylinder A 502 are respectively connected to the plugging plate support frame 503. The rotating plugging plate 504 is located on the side of the plugging plate support frame 503 close to the discharging opening at the lower end of the roller 401. One end of the plugging plate rotating shaft 505 is fixed to the rotating plugging plate 504. A rotating bearing seat 506 is arranged on the plugging plate support frame 503. The other end of the plugging plate rotating shaft 505 is rotatably connected to the rotating bearing seat 506 through a rotating bearing 507. In this embodiment, the cylinders A 502 are all commercially available products and are controlled by an external control system.

[0051] When the driving ends of each cylinder A 502 are in the retracted state, the rotating plugging plate 504 is driven to move through the plugging plate support frame 503. The rotating plugging plate 504 covers the discharging opening at the lower end of the roller 401 and can rotate together with the roller 401 to ensure that the mixed capsules and powdery materials do not leak when the roller 401 rotates. When the driving ends of each cylinder A 502 are in the extended state, the rotating plugging plate 504 is driven to move through the plugging plate support frame 503. The rotating plugging plate 504 moves away from the discharging opening at the lower end of the roller 401, so that the capsules in the roller 401 can be discharged.

[0052] One end of four uniformly arranged guide rods A 508 is connected to the plugging plate support frame 503. The other ends of each guide rod A 508 respectively pass through the discharging mechanism base plate 501. The length directions of each guide rod A 508 are all parallel to the axial center line of the roller 401 to ensure the stable movement of the plugging plate support frame 503. A plurality of protective covers C 509 are installed on the side of the discharging mechanism base plate 501 away from the upper mounting plate 6 and outside the roller 401 to play a role in protecting against dust inside.

[0053] Specifically, as Figure 1 、 Figure 9 and Figure 10 shown, in this embodiment, the quantitative feeding mechanism 2 includes a diversion groove 201 and two groups of cooperatively arranged bins 202, feeding baffles 203, and cylinders B 204.

[0054] The silos 202 of each group have openings at both the upper and lower ends. The outer sides of the silos 202 of each group are fixedly connected to the frame body 1 respectively. The silos 202 of each group are all located above the upper mounting plate 6. The outer shells of the cylinders B 204 of each group are mounted on the upper mounting plate 6. The driving ends of the cylinders B 204 of each group are connected to the feeding baffle plates 203 of the same group. The driving ends of the cylinders B 204 of each group stretch and drive the feeding baffle plates 203 of the same group to block or open the lower openings of the silos 202 of the same group. In this embodiment, the cylinders B 204 are all commercially available products and are controlled by an external control system. The diversion chute 201 has openings at both the upper and lower ends. The upper opening of the diversion chute 201 is mounted on the lower surface of the upper mounting plate 6. The setting position of the upper opening of the diversion chute 201 corresponds to the lower openings of all the silos 202. Capsule passing holes are respectively opened on the upper mounting plate 6 corresponding to the lower openings of the respective silos 202. The lower opening of the diversion chute 201 serves as the capsule output end of the quantitative feeding mechanism 2 and is connected to the upper end of the collecting pipe 9. The diversion chute 201 enables the capsules output from the respective silos 202 to enter the collecting pipe 9 uniformly through the diversion chute 201.

[0055] In this embodiment, the two groups of silos 202 are arranged parallel to each other. In this embodiment, the quantitative feeding mechanism 2 further includes a feeding switching component base 205, a feeding switching hopper 206, and a cylinder C 207. The feeding switching component base 205 is respectively connected to the upper openings of the two groups of silos 202. Silo doors 211 are respectively hinged on both sides of the feeding switching component base 205. Each silo door 211 is respectively used to close or open the upper opening of a corresponding silo 202, which is convenient for use such as maintenance. A main feeding port is opened on the feeding switching component base 205. The main feeding port is respectively communicated with the upper openings of the two groups of silos 202. The outer shell of the cylinder C 207 is mounted on the feeding switching component base 205 at a position outside the main feeding port. The driving end of the cylinder C 207 is fixedly connected to the outer side surface of the feeding switching hopper 206. The feeding switching hopper 206 is located above the main feeding port. The feeding switching hopper 206 has openings at both the upper and lower ends. In this embodiment, the cylinders C 207 are all commercially available products and are controlled by an external control system. In this embodiment, a protective cover A 210 is further provided on the feeding switching component base 205. The protective cover A 210 is used to cover the feeding switching hopper 206 and the cylinder C 207 and play a role in dust protection. The protective cover A 210 is provided with a main feeding hole corresponding to the upper opening of the feeding switching hopper 206. The main feeding hole can be used to connect an external feeding pipeline and input capsules into the quantitative feeding mechanism 2.

[0056] The telescopic movement of the driving end of the air cylinder C 207 drives the feeding switching hopper 206 to move, so that the lower opening of the feeding switching hopper 206 corresponds to the upper opening of one group of bins 202 or the upper opening of the other group of bins 202. Thus, the input capsules can be controlled to enter the corresponding bins 202, and a predetermined amount of capsules are input and stored separately in each bin 202 during use.

[0057] On the upper mounting plate 6, guide rods B 208 are respectively installed at positions on both sides of the moving direction of each group of feeding baffles 203. Each guide rod B 208 passes through the corresponding feeding baffle 203, and the length directions of the respective guide rods B 208 are parallel to the moving direction of the corresponding feeding baffle 203 to ensure the stable movement of the feeding baffle 203. On the feeding switching assembly base 205, guide rods C 209 are respectively installed at positions on both sides of the moving direction of the feeding switching hopper 206. Each guide rod C 209 passes through the feeding switching hopper 206, and the length directions of the respective guide rods C 209 are parallel to the moving direction of the feeding switching hopper 206 to ensure the stable movement of the feeding switching hopper 206.

In this embodiment, one end of a charging pipe 316 is also communicated with the cylinder 307. The other end of the charging pipe 316 has an opening and is closed by a cover B 317. The setting of the charging pipe 316 facilitates the user to simply input powdery material into the cylinder 307.

[0059] The driving end of cylinder D 302 extends and retracts, driving the feed valve core shaft 303 to move axially within the valve core shaft passage, connecting the powder holding groove 3031 with the inner hole of the guide sleeve 305, or simultaneously with the discharge hole 3041 and the air inlet hole 3042. A linear bearing 315, through which the feed valve core shaft 303 passes, is also provided on the outside of the feed valve block 304 to ensure accurate movement of the feed valve core shaft 303.

[0060] The powder holding tank 3031 contains a capacity adjustment block 312. An adjusting rod 313 is provided inside the other end of the feeding valve core shaft 303 away from the cylinder D 302 along the axial direction of the feeding valve core shaft 303. A threaded portion A is provided at the end of the adjusting rod 313 close to the cylinder D 302.

The space formed between one side of 302 and the side of the powder holding tank 3031 close to the cylinder D 302 is the powder holding space 30311. A protective cover B 319 is also provided on the feeding mechanism base plate 301 to cover and protect the point where the feeding valve core shaft 303 passes through.

[0061] Initially, the driving end of cylinder D 302 is retracted, allowing the powdered material in barrel 307 to flow through the lower opening of barrel 307 and the guide sleeve 305 into the aforementioned powder storage space 30311, which holds a fixed volume of powdered material. The driving end of cylinder D 302 then extends, allowing powder storage space 30311 to simultaneously align with both discharge port 3041 and air inlet 3042. An external air supply device then blows compressed air through air inlet 3042, allowing the powdered material in powder storage space 30311 to reliably and fully flow through guide tube 309 and into manifold 9. The provision of powder micro-feeding mechanism 3 effectively prevents problems such as excessive amounts of powdered material exceeding the pharmacopoeial range or insufficient amounts affecting lubricity.

[0062] Rotate the adjustment rod 313 to drive the capacity adjustment block 312 to rotate axially along the feeding valve core shaft 303 in the powder containing groove 3031, thereby adjusting the distance between one side of the capacity adjustment block 312 close to the cylinder D 302 and one side of the powder containing groove 3031 close to the cylinder D 302, and changing the volume of the powder containing space 30311, so that the injection amount of the powdery material can be adjusted according to different usage requirements.

[0063] When the nut 314 is tightened, the nut 314 presses the limit bushing 315, and the limit bushing 315 further presses the limit stop edge of the adjustment rod 313 between the limit bushing 315 and the other end face of the feeding valve core shaft 303, thereby restricting the axial rotation of the adjustment rod 313.

[0064] Working principle:

[0065] During use, first inject a predetermined amount of capsules into the two bins 202 respectively and temporarily store the capsules, and load the powdery material into the cartridge 307; when the equipment needs to feed and start the process, the cylinder A 502 in the discharging mechanism 5 is in the retracted state, the rotary sealing plate 504 is in close fit with the drum 401, and the cylinder B 204 corresponding to one group of bins 202 is controlled to push the feeding baffle 203, so that the feeding baffle 203 is moved away from the lower opening of the same group of bins 202. At this time, the gelatin hollow capsules in the bin 202 flow into the drum 401 through the diversion groove 201 and the collecting pipe 9. During the flow of the capsules, compressed air conveys the powdery material from the powder micro-feeding mechanism 3 to the drum 401 to complete the addition of the powdery material; when the gelatin hollow capsules and the powdery material flow into the drum 401, the drum drive motor 403 starts to operate, drives the drum 401 to rotate through the gear 406 and the slewing bearing 402, and drives the driving gear 404 to rotate the drum 401, so as to realize the mixing of the capsules and the powdery material under the action of rolling and stirring; when the materials are stirred to the system set time, the cylinder A 502 extends, the rotary sealing plate 504 is separated from the drum 401, and the materials flow out of the drum 401 to complete this process flow. During the stirring of the materials, the bin 202 for emptying the capsules can be re-loaded with capsules. Since the time for inputting capsules into the bin 202 is longer than the stirring and mixing time, another bin 202 with stored capsules can be used to inject capsules into the drum 401 next time, and the two bins 202 are switched to use to realize continuous feeding, effectively reducing the process time for continuous use.
