Description

Technical Field

[0001] The utility model relates to the technical field of soft capsule production and processing, and particularly relates to a liquid conveying device for soft capsule production and processing. Background Art

[0002] Soft capsules are a new dosage form that can quantitatively inject and encapsulate nutrient solutions, oily drugs, drug suspensions, drug powders, pastes, etc. into capsules to form sealed capsules with regular shapes and different sizes.

[0003] For example, a liquid conveying device for soft capsule production and processing with the patent number CN220496208U includes a pill pressing machine and a filtering tank. The filtering tank includes a filtering tank body, a filter plate arranged on the filtering tank body, and filter holes arranged on the filter plate; a first liquid conveying pipe is arranged on the filtering tank body on one side of the filter plate, and the filtering tank body on the other side of the filter plate is communicated with the pill pressing machine. The above document still has deficiencies. When in use, it is necessary to reduce the feeding of large-particle materials into the filter hole plate and be able to send the large-particle materials filtered by the filter hole plate back to the colloid mill for re-grinding, reducing the cleaning cycle of the orifice plate blocked by large-particle materials and reducing the frequency of manual disassembly and maintenance. A viscosity sensor, an on-line chromatograph, and a temperature sensor are arranged on the glue liquid conveying pipe between the second regulating valve and the third booster pump, so as to facilitate the feedback of the viscosity parameter, component parameter, and temperature parameter of the glue liquid conveyed through the glue liquid conveying pipe. However, the materials in the tank are directly conveyed into the colloid mill through a pipeline after being mixed. The volume in the colloid mill is fixed, and the materials that cannot enter the colloid mill will accumulate in the pipeline. If the accumulation time is long, the materials are prone to precipitate, thereby affecting the quality of the materials. When in use, it is not convenient to convey a fixed amount of materials into the colloid mill. At the same time, the filter screen in the filter filters the particulate matter in the liquid. When filtering, the particulate matter is prone to accumulate on the surface of the filter screen, blocking the filter screen and thus affecting the passage of the liquid. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the problem that it is not convenient to convey a fixed amount of materials into the colloid mill, and a liquid conveying device for soft capsule production and processing is proposed.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0006] Design a liquid conveying device for soft capsule production and processing, including a base and a tank body. The base is fixedly connected to the tank body through a support column. A quantitative mechanism is arranged below the tank body. The base is fixedly connected to a filtering tank through a cushion block. An anti-blocking mechanism is arranged inside the filtering tank. A filter screen is fixedly connected to the inner wall of the filtering tank. The filtering tank is communicated with the pill pressing machine through a first pipeline. The pill pressing machine is fixedly connected to the upper surface of the base.

[0007] Preferably, the metering mechanism includes a barrel fixedly connected to the lower surface of the tank body. The barrel is communicated with the tank body. An eccentric wheel is rotatably connected to the lower part of the barrel through a bearing. A support rod is fixedly connected to the surface of the eccentric wheel. The outer wall of the eccentric wheel is in contact with a slide rod. The outer wall of the slide rod is slidably connected to the barrel. A spring is sleeved on the outer wall of the slide rod, and both ends of the spring are fixedly connected to the slide rod and the barrel respectively. The upper end of the slide rod is fixedly connected to a piston, and the outer wall of the piston is in contact with the outer wall at the discharge port of the tank body.

[0008] Preferably, the anti-blocking mechanism includes a vertical rod fixedly connected to the inner wall of the filter tank. The vertical rod is rotatably connected to the outer wall of a rotating rod through a bearing. Four impellers are fixedly connected to the outer wall of the rotating rod. A connecting rod is fixedly connected to the outer wall of the rotating rod. A cleaning brush is fixedly connected to the outer wall of the connecting rod, and the cleaning brush is in contact with the outer wall of the filter net.

[0009] Preferably, the filter tank is communicated with a hydrocyclone through a second pipeline, and the filter tank and the hydrocyclone are respectively fixedly connected to both ends of a third pipeline.

[0010] Preferably, the hydrocyclone is communicated with a colloid mill, and a fourth pipeline is fixedly connected to the left side of the colloid mill.

[0011] Preferably, the end of the fourth pipeline is fixedly connected to the barrel.

[0012] The beneficial effect of a liquid conveying device for soft capsule production and processing proposed by the present utility model is as follows: Through the cooperation among the barrel, the eccentric wheel, the support rod, the slide rod, the spring and the piston, the support rod drives the eccentric wheel to rotate, the eccentric wheel drives the slide rod to slide, the slide rod drives the piston to move, the piston separates from the feeding port of the tank body, and the material inside the tank body enters into the barrel and fills the inside of the barrel. When the support rod rotates in the reverse direction, the piston moves in the opposite direction to the above-mentioned movement direction, and the piston blocks the feeding port of the tank body. The high-pressure pump on the outer wall of the fourth pipeline conveys the material inside the barrel into the colloid mill. The volume of the barrel is fixed, and the amount of material entering the colloid mill each time is fixed, avoiding the accumulation of material in the fourth pipeline. When in use, it is convenient to convey a fixed amount of material into the colloid mill.

[0013] Through the cooperation among the vertical rod, the rotating rod, the impeller, the connecting rod and the cleaning brush, when the liquid enters the filter tank through the third pipeline, the liquid flushes the impeller to drive the impeller to rotate. The impeller drives the rotating rod to rotate, the rotating rod drives the connecting rod to rotate, and the connecting rod drives the cleaning brush to rotate. When the cleaning brush rotates, it cleans the filter net, avoiding the particles in the liquid from adhering to the surface of the filter net and causing blockage to the filter net. When filtering, the particulate matter is not likely to accumulate on the surface of the filter net to cause blockage to the filter net, and thus will not affect the passage of the liquid.

The outer wall of the piston 306 is in contact with the outer wall at the discharge port of the tank body 2. The piston 306 blocks the discharge port of the tank body 2.

[0027] The rod 301 drives the eccentric wheel 302 to rotate. The eccentric wheel 302 drives the sliding rod 304 to slide. The sliding rod 304 drives the piston 306 to move.

[0028] The anti-blocking mechanism 4 includes a vertical rod 401, a rotating rod 402, an impeller 403, a connecting rod 404 and a cleaning brush 405. The vertical rod 401 is fixedly connected to the inner wall of the filter tank 5. The outer wall of the vertical rod 401 is rotatably connected to the outer wall of the rotating rod 402 through a bearing. The vertical rod 401 supports the rotating rod 402. Four impellers 403 are fixedly connected to the outer wall of the rotating rod 402, and the impeller 403 drives the rotating rod 402 to rotate;

The impeller 403 drives the rotating rod 402 to rotate. The rotating rod 402 drives the connecting rod 404 to rotate. The connecting rod 404 drives the cleaning brush 405 to rotate. When the cleaning brush 405 rotates, it cleans the filter screen 6, preventing the particles in the liquid from adhering to the surface of the filter screen 6 and blocking the filter screen 6. During filtration, particulate matter is not likely to accumulate on the surface of the filter screen 6 and block the filter screen 6, thus not affecting the passage of the liquid.

[0031] Working principle:

[0032] When the liquid device for soft capsule production and processing is in use, a preset amount of glycerol and purified water are put into the interior of the tank body 2. The heating wire heats the interior of the tank body 2, and the preset temperature is 65°C to 75°C. A preset amount of gelatin is put in, and the stirring mechanism inside the tank body 2 stirs the added materials;

[0033] Quantitative mechanism:

[0034] After the materials inside the tank body 2 are evenly mixed, the rotating support rod 301 is rotated. The support rod 301 drives the eccentric wheel 302 to rotate. The eccentric wheel 302 drives the sliding rod 304 to slide. The sliding rod 304 drives the piston 306 to move. The piston 306 separates from the material outlet of the tank body 2. The materials inside the tank body 2 enter the interior of the barrel 301 and fill the interior of the barrel 301. The support rod 303 is rotated in the reverse direction, and the piston 306 moves in the opposite direction to the above-mentioned movement direction. The piston 306 blocks the material outlet of the tank body 2. The high-pressure pump on the outer wall of the fourth pipeline 12 transports the materials inside the barrel 301 to the interior of the colloid mill 11. The volume of the barrel 301 is fixed, and the amount of materials entering the colloid mill 11 each time is fixed, preventing the materials from accumulating inside the fourth pipeline 12. During use, it is convenient to transport a fixed amount of materials into the colloid mill 11;

[0035] Pill pressing and processing stage:

[0036] The colloid mill 11 processes the material. After processing, the material enters the hydrocyclone 10 to form a liquid. The liquid enters the filter tank 5 through the third pipeline 9. The filter screen 6 filters the particles in the liquid. The liquid enters the inside of the pill press 13 through the first pipeline 7 via the filter screen 6 for soft capsule production and processing, completing the liquid transportation for soft capsule production and processing. The particles that cannot pass through the filter screen 6 return to the hydrocyclone 10 through the second pipeline 8;

[0037] Anti-blocking stage:

[0038] When the liquid enters the filter tank 5 from the third pipeline 9, the liquid flushes the impeller 403 to drive the impeller 403 to rotate. The impeller 403 drives the rotating rod 402 to rotate. The rotating rod 402 drives the connecting rod 404 to rotate. The connecting rod 404 drives the cleaning brush 405 to rotate. When the cleaning brush 405 rotates, it cleans the filter screen 6, preventing the particles in the liquid from adhering to the surface of the filter screen 6 and causing blockage to the filter screen 6. During filtration, the particulate matter is not likely to accumulate on the surface of the filter screen 6 to cause blockage to the filter screen 6, and thus will not affect the passage of the liquid.

[0039] Embodiment 2:

[0040] Refer to the appendix Figure 1-6 In this embodiment, for a liquid transportation device for soft capsule production and processing, the metering mechanism 3 further includes a rubber sleeve 3a1. The rubber sleeve 3a1 wraps around the outer wall of the support rod 303 to protect the friction between the hand and the support rod 303;

[0041] Due to the action of the rubber sleeve 3a1, when the staff rotates the support rod 303, the hand of the staff contacts the support rod 303 through the rubber sleeve 3a1, and the rubber sleeve 3a1 protects the friction between the hand and the support rod 303.

[0042] Working principle:

[0043] When the staff rotates the support rod 303, the hand of the staff contacts the support rod 303 through the rubber sleeve 3a1, and the rubber sleeve 3a1 protects the friction between the hand and the support rod 303.
