Description

Technical Field

[0001] This utility model is a pharmaceutical preparation filling equipment, belonging to the field of filling technology. Background Technology

[0002] In the filling stage of formulation production, the filling pipe installed at the outlet of the storage silo is the core channel connecting the formulation and the filling container. The prepared formulation (such as liquid or ointment) in the storage silo flows continuously along the filling pipe by gravity or pressure, precisely injecting it into the filling container (such as a glass bottle or plastic bottle) below, completing the quantitative dispensing. This process requires that, according to production needs, after filling one container, the position of the next container be quickly adjusted to ensure precise alignment with the outlet of the filling pipe, achieving continuous production.

[0003] During the gap caused by adjusting the position of adjacent containers, residual formulation in the filling tube will drip due to the lack of a container to hold it. From the perspective of the cause of residue, the inner wall of the filling tube will adsorb some formulation (especially highly viscous pastes and emulsions). Even if the feeding is paused, the residual formulation in the tube will slowly seep downwards under gravity. If the outlet of the filling tube is not drip-proofed, this residual formulation will drip onto the production table, floor, or equipment surface during the brief gap of adjusting the container. This dripping phenomenon causes two problems: firstly, it causes formulation waste, especially for high-value pharmaceutical or precision chemical formulations; frequent dripping will accumulate into considerable material loss, increasing production costs. Secondly, it seriously affects the cleanliness of the working environment. If the dripped formulation is liquid, it will form stains on the table that are difficult to clean after drying; if it is viscous, it will also attract dust and impurities, not only damaging the sanitary environment of the production area but also potentially affecting the quality of subsequent fillings due to cross-contamination, failing to meet the strict hygiene requirements of the production environment. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a formulation filling device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a formulation filling device, comprising: Base; The storage bin has a three-way switching valve installed at the lower end, and the three-way switching valve is installed on the upper surface of the base. The dispensing unit, installed on the upper surface of the base and used in conjunction with the three-way switching valve, is used to remove the formulation from the storage hopper; A discharge pipe is installed at one end of a three-way switching valve. A connecting chamber is installed at the end of the discharge pipe away from the three-way switching valve. A filling pipe is installed at the lower end of the connecting chamber.

[0006] Furthermore, the filling component includes a filling cylinder, which is mounted on the upper surface of the base. One end of the filling cylinder is connected to a three-way switching valve. A piston is slidably installed inside the filling cylinder. A connecting rod is mounted on one side of the piston.

[0015] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0016] Please see Figures 1-4 This utility model provides a technical solution: a formulation filling device, including a base 1 with a "U"-shaped cross-section. A three-way switching valve 31 is installed at the lower end of a storage bin 3. The three-way switching valve 31 is installed on the upper surface of the base 1. A filling cylinder 2 is installed on the upper surface of the base 1. One end of the filling cylinder 2 is connected to the three-way switching valve 31. A piston 26 is slidably installed inside the filling cylinder 2. A connecting rod 23 is installed on one side of the piston 26. The end of the connecting rod 23 away from the piston 26 extends to the outside of the filling cylinder 2. A first cylinder 25 is installed on the upper surface of the base 1. The first cylinder 25 is arranged parallel to the connecting rod 23. A movable seat 22 is installed on the end of the connecting rod 23 away from the piston 26, so that the movable end of the first cylinder 25 is connected to the movable seat 22, thus completing the connection between the movable end of the first cylinder 25 and the end of the connecting rod 23 away from the piston 26.

[0017] A positioning seat 27 is installed on the upper surface of the base 1 by screws. The cylinder end of the first cylinder 25 is connected to the positioning seat 27 by bolts. The positioning seat 27 is sleeved on the filling cylinder 2. A clamp 21 is sleeved on the end of the filling cylinder 2 away from the three-way switching valve 31. The clamp 21 is connected to the base 1 by screws. A support 24 is installed on the end of the cylinder end of the first cylinder 25 away from the positioning seat 27. The support 24 is connected to the base 1 by screws. The support 24, clamp 21 and positioning seat 27 provide support and limit the filling cylinder 2 and the first cylinder 25. A connecting seat 6 is provided inside the base 1 so that the screws pass through the connecting seat 6 and the base 1 and are connected to the corresponding components. This distributes the force on the screws to multiple parts of the base 1, which helps to reduce the requirements for the wall thickness of the base 1. The first cylinder 25 drives the connecting rod 23 to drive the piston 26 to reciprocate. When the piston 26 retracts, the preparation in the storage bin 3 is sucked into the dispensing cylinder 2 through the three-way switching valve 31 to achieve quantitative material dispensing. When the piston 26 moves forward, it pushes the preparation to the discharge pipe 4 and then injects it into the filling container through the filling pipe 42. This quantitative material dispensing method can accurately control the single filling dosage. The third cylinder 32 is rotatably installed on the upper surface of the base 1. The movable end of the third cylinder 32 is rotatably connected to the valve core in the three-way switching valve 31. When the third cylinder 32 extends or retracts, it can switch the passage of the three-way switching valve 31, so that the dispensing cylinder 2 is connected to the internal space of the storage bin 3 or to the discharge pipe 4, so as to achieve orderly switching between material dispensing and material retrieval.

[0018] See Figures 1-4The discharge pipe 4 is installed at one end of the three-way switching valve 31. A connecting chamber 41 is installed at the end of the discharge pipe 4 away from the three-way switching valve 31. A filling pipe 42 is installed at the lower end of the connecting chamber 41. A vertically arranged second cylinder 5 is provided on the upper side of the connecting chamber 41. A lower ring 43 is installed at the upper end of the connecting chamber 41. An upper ring 52 is installed on the upper side of the lower ring 43. Two rods 51 are installed on the lower surface of the cylinder body end of the second cylinder 5. The rods 51, the upper ring 52 and the lower ring 43 are connected by hexagonal socket head cap screws. A rubber column 53 is installed at the movable end of the second cylinder 5. The rubber column 53 passes through the upper ring 52 and extends into the connecting chamber 41. The outer diameter of the rubber column 53 is the same as the inner diameter of the upper ring 52 and the inner diameter of the filling pipe 42. The outer diameter of the rubber column 53, driven by the second cylinder 5, is perfectly matched to the inner diameter of the filling tube 42. Before the adjacent filling container is repositioned, the second cylinder 5 is activated to push the rubber column 53 downwards along the inner wall of the filling tube 42, thoroughly scraping away the adsorbed formulation inside the filling tube 42. The scraped formulation falls into the filling container below as the rubber column 53 moves. During the interval between switching filling container positions, no residual formulation drips from the filling tube 42, avoiding waste caused by formulation dripping, reducing material loss of high-value formulations, lowering production costs, and maintaining a clean working environment. The entire cleaning process does not require manual disassembly or wiping of the filling tube 42, avoiding interruptions to the production process due to manual operation, achieving seamless connection between filling, cleaning, and container changing, significantly improving production efficiency. Furthermore, the rubber column 53 is soft and will not scratch the inner wall of the filling tube 42, ensuring the sealing and smooth operation of the filling tube 42 for long-term use.
