Description

Technical Field

[0001] This utility model relates to the field of oral liquid production technology, and in particular to an oral liquid dispensing device. Background Technology

[0002] In the pharmaceutical manufacturing industry, oral liquids are widely used due to their advantages such as precise dosage and convenient administration. The efficiency, accuracy, and material utilization rate of the filling process directly affect product quality and production costs. Currently, there are many types of oral liquid filling equipment on the market, but they generally suffer from problems such as insufficient material supply stability, low filling efficiency, and bottle positioning deviation. For example, a Chinese patent proposes an oral liquid filling device, patent publication number CN223118111U. When in use, the above patent realizes the automated filling of oral liquid through the cooperation of the filling head and the conveying mechanism, which replaces manual operation to a certain extent and improves the convenience of production. However, the above patent only solves the problem of low efficiency of manual filling, and does not optimize the design for the stability of the feeding pressure, the accuracy of multi-channel synchronization and the reliability of bottle positioning. The applicant discovered the following shortcomings when implementing the above plan: 1. The device does not have an overflow return structure, so the pipeline pressure is prone to be too high or fluctuating during the material conveying process. This not only affects the continuity of material conveying, but may also lead to an increase in filling accuracy deviation. At the same time, excess material cannot be recovered, resulting in raw material waste. 2. The device lacks a synchronous clamping and positioning structure adapted to multi-channel filling during use. The bottle is prone to displacement or tipping during filling, resulting in material spillage. Furthermore, the single-channel or limited-channel design results in low dispensing efficiency, making it difficult to adapt to large-scale production scenarios and thus reducing the practicality of the device.

[0003] Therefore, we propose an oral liquid dispensing device to solve the above problems. Utility Model Content

Detailed Implementation

[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0017] Reference Figure 1-5 An oral liquid dispensing device includes a workbench 1, and further includes: A distribution pipe 3 is fixedly installed on one side of the workbench 1, and the distribution pipe 3 is connected to a conveying pump 4. The other end of the conveying pump 4 is connected to a storage tank 2 through a pipe. Eight sets of parallel extrusion cylinders 6 are fixedly installed on the top of the workbench 1 near the distribution pipe 3, and an extrusion structure is provided inside the workbench 1 corresponding to the eight sets of extrusion cylinders 6. A conveyor belt 7 is fixedly installed on the top of the workbench 1 away from the side of the extrusion cylinder 6, and a needle bracket is fixedly installed on the top of the workbench 1 near the conveyor belt 7. A clamping assembly 8 is provided on the side of the workbench 1 near the middle of the conveyor belt 7.

[0018] Furthermore, an overflow pipe 5 is installed on one side of the distribution pipe 3, and the other end of the overflow pipe 5 is connected to the top of the storage tank 2. By installing an overflow pipe 5 on one side of the distribution pipe 3 and connecting the other end of the overflow pipe 5 to the top of the storage tank 2, excess material in the distribution pipe 3 can be returned to the storage tank 2 in a timely manner, avoiding excessive pressure in the distribution pipe 3 from affecting the stability of material conveying. At the same time, the material can be recycled, reducing material waste and ensuring the continuous and efficient operation of the packaging process.

[0019] Furthermore, a one-way valve is fixedly installed on one side of the squeezing cylinder 6, and eight sets of parallel needles are fixedly installed inside the needle holder. A set of conveying pipes is fixedly installed at the one-way valves of the eight squeezing cylinders 6, and the other end of each conveying pipe is fixedly connected to the top of the distribution pipe 3. The tops of the eight squeezing cylinders 6 are connected to the eight sets of needles through connecting pipes. The one-way valve fixedly installed on one side of the squeezing cylinder 6 can effectively prevent material backflow and ensure the unidirectionality and accuracy of material conveying. The eight sets of parallel needles fixed inside the needle holder correspond one-to-one with the eight sets of squeezing cylinders 6 through connecting pipes. With the connection of the conveying pipes between the squeezing cylinders 6 and the distribution pipe 3, the synchronous feeding and dispensing operations of the eight channels are realized, which greatly improves the dispensing efficiency of oral liquid. Moreover, the multiple parallel structures ensure the uniformity of material distribution in each dispensing channel and improve the product dispensing accuracy.

[0020] Furthermore, the extrusion structure includes a first pneumatic telescopic rod 9, a mounting plate 10, and piston rods 11. A set of first pneumatic telescopic rods 9 is fixedly installed on both sides of the bottom of the workbench 1, and a mounting plate 10 is fixedly installed between the output ends of the two sets of first pneumatic telescopic rods 9. A set of piston rods 11 is fixedly installed at the top of the mounting plate 10 corresponding to the eight sets of extrusion cylinders 6, and the other ends of the multiple sets of piston rods 11 extend into the interior of the extrusion cylinders 6 and are fixedly installed with pistons. The extrusion structure uses two sets of first pneumatic telescopic rods 9 to drive the mounting plate 10 to lift and lower synchronously. The eight sets of piston rods 11 at the top of the mounting plate 10 extend into the interior of the eight sets of extrusion cylinders 6 and drive the pistons to move. The synchronous extrusion action of the eight sets of extrusion cylinders 6 is realized through pneumatic drive. The driving force is stable and controllable, and the output of the extrusion cylinders 6 can be accurately controlled, thereby ensuring the consistency of the dispensing dosage of each oral liquid. At the same time, the structural design is simple, easy to maintain and debug, and reduces the equipment failure rate.

[0021] Furthermore, the clamping assembly 8 includes a fixed plate 12, a slide rail 13, a second pneumatic telescopic rod 14, and a push plate 15. A T-shaped fixed plate 12 is fixedly installed at the bottom end of the worktable 1 near the conveyor belt 7. The second pneumatic telescopic rod 14 is fixedly installed on one side of the fixed plate 12, and the slide rail 13 is fixedly installed on the side of the fixed plate 12 away from the second pneumatic telescopic rod 14. An L-shaped push plate 15 is fixedly installed at the output end of the second pneumatic telescopic rod 14. The T-shaped fixed plate 12 in the clamping assembly 8 provides a stable mounting base for the second pneumatic telescopic rod 14 and the slide rail 13. The second pneumatic telescopic rod 14 drives the L-shaped push plate 15 to move. With the guiding effect of the slide rail 13, the movement of the push plate 15 is more stable and reliable, providing stable power transmission and motion guidance for subsequent clamping actions. This ensures that the clamping assembly 8 can respond quickly and execute clamping actions accurately, and guarantees the positioning stability of the oral liquid bottle during the conveying process.

[0022] Furthermore, the clamping assembly 8 also includes clamping plates 16 and connecting rods 17. Two sets of connecting rods 17 are hinged to the bottom end of the push plate 15 on the side opposite to the second pneumatic telescopic rod 14. A set of clamping plates 16 are slidably installed on both sides of the top of the slide rail 13, and the tops of the two sets of clamping plates 16 have eight semi-circular openings. The other ends of the two sets of connecting rods 17 are hinged to the bottom ends of the two sets of clamping plates 16. The push plate 15 is hinged to the two sets of clamping plates 16 at the top of the slide rail 13 via the two sets of connecting rods 17, forming a linkage structure. When the push plate 15 moves, it can... The connecting rod 17 drives the two sets of clamping plates 16 to move synchronously relative to each other or in opposite directions along the slide rail 13, realizing the rapid clamping and releasing of the oral liquid bottle; the eight semi-circular openings at the top of the two sets of clamping plates 16 can correspond one-to-one with the eight sets of needles, accurately adapting to the eight sets of synchronous dispensing channels, and can simultaneously position and clamp eight oral liquid bottles, which not only ensures the stability of the oral liquid bottles during dispensing and avoids dispensing deviations caused by bottle tilting or displacement, but also matches the eight sets of synchronous dispensing structure, further improving the overall dispensing efficiency and ensuring the continuity and accuracy of the dispensing process.

[0023] In summary: The oral liquid material in the storage tank 2 is pumped into the distribution pipe 3 by the conveying pump 4. The distribution pipe 3 conveys the material to eight extrusion cylinders 6 through multiple sets of conveying pipes (during the conveying process, the one-way valve on one side of the extrusion cylinder 6 prevents the material from flowing back and ensures that the material enters the extrusion cylinder 6 in one direction). When the material pressure in the distribution pipe 3 is too high, the excess material flows back to the storage tank 2 through the overflow pipe 5, realizing material recycling and stabilizing the pressure in the distribution pipe 3, ensuring continuous material supply. When the conveyor belt 7 transports the oral liquid bottle to below the needle, the clamping assembly 8 is activated: the second pneumatic telescopic rod 14 drives the L-shaped push plate 15 to move. The push plate 15 drives the two sets of clamping plates 16 at the top of the slide rail 13 to move synchronously relative to each other along the slide rail 13 through two sets of connecting rods 17. The eight sets of semi-circular openings at the top of the clamping plates 16 are used to accurately clamp and position the eight oral liquid bottles (corresponding one-to-one with the eight sets of needles), preventing the bottles from shifting during dispensing. Subsequently, the squeezing structure is activated: the two sets of first pneumatic telescopic rods 9 extend synchronously, driving the mounting plate 10 to rise. The eight sets of piston rods 11 at the top of the 10 push the piston in the squeezing cylinder 6 upward, pressing the material in the squeezing cylinder 6 into the corresponding eight sets of needles through the connecting pipe. The needles inject the material quantitatively into the eight oral liquid bottles that are clamped and positioned, completing the synchronous dispensing. After dispensing, the first pneumatic telescopic rod 9 retracts, driving the piston rod 11 and piston to reset. A negative pressure is formed in the squeezing cylinder 6, and new material is sucked in from the distribution pipe 3 through the one-way valve and the conveying pipe, preparing for the next dispensing. At the same time, the second pneumatic telescopic rod 14 resets, and the push plate 15 drives the two sets of clamping plates 16 to move in opposite directions through the connecting rod 17, releasing the oral liquid bottles. The conveyor belt 7 transports the dispensed oral liquid bottles to the next process. This cycle achieves continuous and efficient oral liquid dispensing operation.
