Description

Technical Field

[0001] This utility model relates to the technical field of material filling devices, specifically to a double-layer material filling device for nicotinic acid sustained-release tablets. Background Technology

[0002] Nicotinic acid sustained-release tablets are a type of drug used to treat hyperlipidemia. They consist of a core drug layer and a sustained-release coating layer. The dual-layer material filling device for nicotinic acid sustained-release tablets is mainly used to fill the two different materials, usually the core drug layer and the sustained-release coating layer.

[0003] Existing methods for filling the dual-layer nicotinic acid sustained-release tablets mostly rely on conventional tablet filling equipment, which cannot quickly and accurately fill both layers. Furthermore, during filling, the drug core layer and sustained-release coating layer materials stored in the equipment lack corresponding auxiliary protective functions. The drug core layer material suffers from severe stratification, as it is typically composed of a mixture of multiple components that are prone to stratification upon entering the equipment. This results in inconsistent component proportions, severely impacting the stability and uniformity of the nicotinic acid sustained-release tablet's efficacy. Meanwhile, the sustained-release coating layer material is highly hygroscopic, easily absorbing moisture from the air and causing particles to stick together, making it difficult to fill the tablets evenly and accurately. This affects the film-forming quality of the sustained-release coating layer in subsequent processes and the drug's sustained-release performance, making it difficult to guarantee the quality of the nicotinic acid sustained-release tablets. Utility Model Content

[0004] In view of the problems existing in the current double-layer material filling device for nicotinic acid sustained-release tablets, this utility model is proposed.

[0005] Therefore, the purpose of this utility model is to provide a double-layer material filling device for nicotinic acid sustained-release tablets, which solves the problem that existing double-layer materials for nicotinic acid sustained-release tablets lack professional filling devices during the filling process, making it impossible to efficiently and quickly fill the double-layer materials, and the filling process lacks corresponding auxiliary protection functions for the drug core layer material and sustained-release coating layer material stored inside.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0008] The slide rail compartment has second limiting grooves on the side walls at both ends, and two injection pipes are slidably connected thereto. The injection pipes at both ends are fixedly connected. The output ends of the drug tank device and the coating tank device are fixedly connected to flow valves. The tops of the injection pipes at both ends are fixedly connected to the output ends of the flow valves at both ends, respectively. The bottom of the slide rail compartment has a filling tube head fixedly connected through an opening. The bottoms of the injection pipes at both ends are slidably connected to the bottom of the slide rail compartment. The U-shaped support compartment has a drive mechanism fixedly connected to the U-shaped support base and the injection pipes inside. The side wall of the base is fixedly connected to a display controller, and the top of the base is fixedly connected to a fan assembly.

[0009] Preferably, the lifting mechanism includes a hydraulic cylinder, a sliding port, and a limiting slider. The hydraulic cylinder is fixedly connected to one end of the top of the base. A sliding port is opened on one side wall of the base, and a limiting slider is slidably connected thereto. The limiting slider is fixedly connected to the U-shaped support chamber. One side wall of the limiting slider passes through the sliding port and is fixedly connected to one end of the hydraulic cylinder.

[0010] Preferably, the driving mechanism includes a cylinder, a propulsion link, and a sliding hole. The cylinder is fixedly connected inside the cavity of the U-shaped support chamber. One end of the cylinder passes through the side wall of the U-shaped support chamber and is fixedly connected to the propulsion link. The side wall of the slide rail chamber has a sliding hole. One end of the propulsion link passes through the sliding hole and is fixedly connected to the side wall of one of the injection pipes.

[0011] Preferably, a motor is fixedly connected to the top of the drug tank device, one end of the motor passes through the side wall of the drug tank device and is fixedly connected to a stirring plate.

[0014] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0015] 1. This utility model utilizes a hydraulic cylinder installed in the lifting mechanism to push a limit slider to slide in the sliding port, thereby moving the U-shaped support chamber and filling components up and down, facilitating the adjustment of the filling height. A cylinder installed in the drive mechanism pushes a propulsion connecting rod to move the injection pipe and the U-shaped support seat synchronously, allowing injection pipes with different discharges to accurately connect with the filling pipe head.

The coating material tank device is connected to a blower assembly via a connecting pipe and a multi-hole spray pipe. The blower provides airflow, which is sprayed through the multi-hole spray pipe to agitate the coating material, keeping it dry and constantly moving. At the same time, combined with the activated carbon dehumidification sleeve on the inner side wall of the chamber, the drying effect is further enhanced, effectively preventing the coating material from absorbing moisture and sticking together. This provides comprehensive protection for the core drug layer material and the sustained-release coating layer material, improving product quality.

[0017] 3. This utility model utilizes a ceramic anti-stick coating installed inside the cavity of the injection pipe and filling pipe head, which can effectively prevent materials from sticking to the cavity of these components, greatly reducing material residue and simplifying cleaning.

[0024] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0025] This utility model discloses a double-layer material filling device for nicotinic acid sustained-release tablets.

[0026] This utility model provides, for example Figure 1-3 The device for filling a double-layer material of nicotinic acid sustained-release tablets shown includes a base 1. The top of the base 1 is fixedly connected to a U-shaped support chamber 2 via a lifting mechanism. The inner sidewalls at both ends of the U-shaped support chamber 2 are provided with first limiting grooves 3 and are slidably connected to U-shaped support seats 4. The top two ends of the U-shaped support seats 4 are fixedly connected to a drug material tank device 5 and a coating material tank device 6. A slide rail chamber 7 is fixedly connected between the sidewalls of the U-shaped support chamber 2.

[0027] The slide rail compartment 7 has second limiting grooves 8 on both sides of its cavity, and two injection pipes 9 are slidably connected to them. The injection pipes 9 are fixedly connected to each other. The output ends of the drug tank device 5 and the coating tank device 6 are fixedly connected to flow valves 10. The tops of the injection pipes 9 are fixedly connected to the output ends of the flow valves 10 at both ends, respectively. The bottom of the slide rail compartment 7 is fixedly connected to a filling tube head 11 through an opening. The bottoms of the injection pipes 9 are slidably connected to the bottom of the cavity of the slide rail compartment 7. The cavity of the U-shaped support compartment 2 is equipped with a drive mechanism fixedly connected to the U-shaped support seat 4 and the injection pipes 9. The side wall of the base 1 is fixedly connected to a display controller 12, and the top of the base 1 is fixedly connected to a fan assembly 13. Using the U-shaped support compartment 2 set at one end of the lifting mechanism, the filling component is supported while the height of the filling component can be adjusted by the lifting mechanism. Using the U-shaped support seat 4 that slides in the first limiting groove 3 and the two injection pipes 9 that slide in the second limiting groove 8, the filling component is pushed by the drive mechanism. The device allows for the synchronous movement of two injection pipes 9 and U-shaped support base 4. This movement aligns the two injection pipes 9 with different discharge points to the filling head 11. Under control, the material is discharged through the filling head 11 for precise filling. The device utilizes a drug tank 5 and a coating tank 6. The internal structure of the drug tank 5 ensures uniform mixing of the drug material, while the internal structure of the coating tank 6 keeps the coating material dry and prevents adhesion. A flow valve 10 precisely controls the feeding quantity. A display controller 12 facilitates device control. A fan assembly 13 provides airflow to the coating tank for drying. This addresses the problems of existing nicotinic acid sustained-release tablets lacking a professional filling device during the filling process, hindering efficient and rapid filling of the double-layer material, and lacking corresponding auxiliary protection for the internal drug core layer and sustained-release coating layer during the filling process.

[0028] In order to move the filling component at one end up and down, such as Figure 1 and 2 As shown, the lifting mechanism includes a hydraulic cylinder 14, a sliding opening 15, and a limiting slider 16. The hydraulic cylinder 14 is fixedly connected to one end of the top of the base 1. The sliding opening 15 is opened on one side wall of the base 1, and the limiting slider 16 is slidably connected thereto. The limiting slider 16 is fixedly connected to the U-shaped support chamber 2. One side wall of the limiting slider 16 passes through the sliding opening 15 and is fixedly connected to one end of the hydraulic cylinder 14. By using the lifting mechanism composed of the hydraulic cylinder 14, the sliding opening 15, and the limiting slider 16, the limiting slider 16 is pushed by the hydraulic cylinder 14 to slide in the sliding opening 15, thereby driving the filling component at one end to move up and down.

[0029] In order to push the injection pipe 9 and the U-shaped support 4, such as Figure 2As shown, the driving mechanism includes a cylinder 17, a push rod 18, and a sliding hole 19. The cylinder 17 is fixedly connected inside the cavity of the U-shaped support chamber 2. One end of the cylinder 17 passes through the side wall of the U-shaped support chamber 2 and is fixedly connected to the push rod 18. The side wall of the slide rail chamber 7 has a sliding hole 19. One end of the push rod 18 passes through the sliding hole 19 and is fixedly connected to the side wall of one of the injection pipes 9. The other end of the push rod 18 is fixedly connected to the inner side walls of both ends of the U-shaped support seat 4. By using the driving mechanism composed of the cylinder 17, the push rod 18, and the sliding hole 19, the cylinder 17 pushes the push rod 18 to move, thereby causing the push rod 18 to pass through the sliding hole 19 and push the injection pipe 9 and the U-shaped support seat 4.

[0030] To ensure the pharmaceutical materials are thoroughly mixed, such as... Figure 1-3 As shown, a motor 20 is fixedly connected to the top of the drug tank device 5. One end of the motor 20 passes through the side wall of the drug tank device 5 and is fixedly connected to a stirring plate 21. The motor 20 and the stirring plate 21 are used to stir the drug material so that it is mixed evenly.

[0031] To prevent the coating material from absorbing moisture and sticking together, such as Figure 1 and 2 As shown, a connecting pipe 22 is fixedly connected to the top of the coating material tank device 6. One end of the connecting pipe 22 passes through the side wall of the coating material tank device 6 and is fixedly connected to a multi-hole spray pipe 23. An activated carbon dehumidification sleeve 24 is fixedly connected to the inner side wall of the coating material tank device 6. An air outlet filter 25 is opened at the top of the coating material tank device 6. The input end of the connecting pipe 22 is fixedly connected to the output end of the fan assembly 13. Using the multi-hole spray pipe 23 located at the bottom of the connecting pipe 22, after the air source is provided by the fan assembly 13, the air source is sprayed out through the multi-hole spray pipe 23 to keep the coating material dry and make the material move continuously. In conjunction with the activated carbon dehumidification sleeve 24, the drying effect is further enhanced, thereby preventing the coating material from absorbing moisture and sticking together.

[0032] To prevent material from adhering to the cavity of the injection pipe 9 and the filling tube head 11, such as Figure 2 and 3 As shown, the cavity of the injection pipe 9 and the filling pipe head 11 is provided with a ceramic anti-stick coating. The ceramic anti-stick coating is used to prevent the material from sticking to the cavity of the injection pipe 9 and the filling pipe head 11.
