Description

Technical Field

[0001] This utility model relates to the technical field of liquid filling, and more specifically, to a high-viscosity liquid filling device for oral liquid production. Background Technology

[0002] In the chemical and pharmaceutical manufacturing industries, the precise filling of high-viscosity liquids has always been a technical challenge. Taking oral liquids and syrups as examples, these materials with non-Newtonian fluid properties often exhibit a "stringing" phenomenon during the filling process due to strong intermolecular forces and high cohesive forces. This means that when the filling nozzle completes the liquid injection and lifts up, the liquid cannot be stopped in time to form a thin, long, thread-like suspension.

[0003] This adhesion not only leads to filling accuracy deviations, but more importantly, residual liquid strands can easily come into contact with the bottle opening or outer wall during container transfer, causing secondary contamination. For pharmaceutical products with strict aseptic requirements, trace amounts of liquid adhering to the bottle can become a breeding ground for microorganisms, directly affecting product shelf life and medication safety. Therefore, a device can be designed to effectively fill highly viscous liquids. Utility Model Content

[0004] The purpose of this invention is to provide a high-viscosity liquid filling device for oral liquid production, which can effectively prevent high-viscosity liquids from stringing and sticking to the outer wall of the container during filling.

[0005] This utility model is achieved through the following technical solution: The high-viscosity liquid filling device for oral liquid production of this utility model includes a feeding pipe, a vertically arranged first corrugated pipe, a vertically arranged second corrugated pipe, a connecting pipe, a driving device for driving the connecting pipe to rise and fall, a conveyor belt located directly below the second corrugated pipe, and a bottle body located on the conveyor belt; the lower end of the first corrugated pipe is connected to the feeding pipe; the connecting pipe is used to connect the upper end of the first corrugated pipe and the upper end of the second corrugated pipe.

[0006] Furthermore, the lower end of the second corrugated pipe is provided with a filling pipe, which is used to extend into the bottle body.

[0007] Furthermore, the upper sidewall of the infusion pipe is provided with a first connecting plate, the lower side of the first connecting plate is provided with a first telescopic rod, and the lower end of the first telescopic rod is provided with a base plate.

[0008] Furthermore, a second connecting plate is provided on the lower outer wall of the connecting pipe, and a second telescopic rod is provided between the first connecting plate and the second connecting plate.

[0009] Furthermore, a spring is fitted on the outer wall of the second telescopic rod, with one end of the spring connected to the first connecting plate and the other end connected to the second connecting plate.

[0010] Furthermore, the driving device includes a vertically arranged support plate, a bracket for supporting the support plate, a telescopic cylinder vertically arranged on the side wall of the support plate, a driving plate horizontally arranged at the end of the telescopic rod of the telescopic cylinder, and a first connecting rod arranged on the upper side wall of the connecting pipe; the first connecting rod is connected to the driving plate.

[0011] Furthermore, the lower end of the feeding pipe is connected to the lower end of the first corrugated pipe, and the lower end of the feeding pipe is U-shaped; the support plate is disposed between the feeding pipe and the first corrugated pipe, and the lower end sidewall of the feeding pipe is connected to the support plate by a second connecting rod.

[0012] Furthermore, the sidewall of the feeding pipe and the sidewall of the support plate are fixedly connected by a connecting block.

[0013] The technical solution of this utility model has at least the following advantages and beneficial effects: The high-viscosity liquid filling device for oral liquid production of this utility model, during use, uses a pump to deliver a fixed amount of liquid into a feeding pipe, which then sequentially passes through a second corrugated pipe, a connecting pipe, and a first corrugated pipe before being filled into the bottle. After a single bottle is filled, the driving device drives the connecting pipe to rise. During the rising process, the first and second corrugated pipes are stretched, creating a certain suction force on the liquid. This allows the liquid suspended at the lower end of the first corrugated pipe to be drawn into it, effectively preventing the viscous liquid from stringing at the end of the first corrugated pipe and preventing it from adhering to the outside of the bottle during movement. When the next empty bottle moves directly below the first corrugated pipe, the driving device drives the connecting pipe to move downwards, causing the first and second corrugated pipes to retract to their previous positions. This not only does not affect the original filling efficiency and accuracy but also effectively prevents the liquid from contacting areas outside the bottle, thus effectively improving the filling quality.

Detailed Implementation

[0018] Example

[0019] The following description, in conjunction with specific embodiments, further illustrates the point, as shown in the appendix. Figure 1 -Appendix Figure 3 As shown, the high-viscosity liquid filling device for oral liquid production in this embodiment includes a feeding pipe 11, a vertically arranged first corrugated pipe 12, a vertically arranged second corrugated pipe 13, a connecting pipe 14, a driving device 20 for driving the connecting pipe 14 to move up and down, a conveyor belt located directly below the second corrugated pipe 13, and a bottle body located on the conveyor belt; the lower end of the first corrugated pipe 12 is connected to the feeding pipe 11; the connecting pipe 14 is used to connect the upper end of the first corrugated pipe 12 and the upper end of the second corrugated pipe 13. Specifically, during use, a fixed amount of liquid is pumped into the feeding pipe 11, and then sequentially passed through the second corrugated pipe 13, the connecting pipe 14, and the first corrugated pipe 12 before being filled into the bottle. After a single bottle is filled, the driving device 20 drives the connecting pipe 14 to rise. During the rising process of the connecting pipe 14, the first corrugated pipe 12 and the second corrugated pipe 13 are stretched, so that the first corrugated pipe 12 and the second corrugated pipe 13 generate a certain suction force on the liquid, which can draw the liquid suspended at the lower end of the first corrugated pipe 12 into the first corrugated pipe 12. This can effectively prevent viscous liquid from forming threads at the end of the first corrugated pipe 12 and prevent it from adhering to the outside of the bottle during the movement of the bottle. When the next empty bottle moves directly below the first corrugated pipe 12, the driving device 20 drives the connecting pipe 14 to move down, so that the first corrugated pipe 12 and the second corrugated pipe 13 retract to their previous positions. This method will not affect the original filling efficiency and filling accuracy, and can effectively prevent the liquid from coming into contact with parts outside the bottle, thus effectively improving the filling quality.

[0020] In this embodiment, the lower end of the second corrugated pipe 13 is provided with a filling pipe 15, which is used to extend into the bottle body. Specifically, the connecting pipe 14 and the first corrugated pipe 12 are driven to move downward by the driving device 20, so that the filling pipe 15 extends into the bottle body, which enables more accurate filling. The lower end of the second corrugated pipe 13 and the feeding pipe 11 are both fixed.

[0021] In this embodiment, the upper sidewall of the infusion pipe 15 is provided with a first connecting plate 16, the lower side of the first connecting plate 16 is provided with a first telescopic rod 17, and the lower end of the first telescopic rod 17 is provided with a base plate 111. Specifically, by setting the first telescopic rod 17 and the first connecting plate 16, it can be ensured that the infusion pipe 15 and the first corrugated pipe 12 can be raised and lowered stably, and the first telescopic rod 17 can play the role of a lower limit, that is, the lowermost end of the movement range of the first corrugated pipe 12 can be fixed by the first telescopic rod 17.

[0022] In this embodiment, a second connecting plate 18 is provided on the lower outer wall of the connecting pipe 14, and a second telescopic rod 19 is provided between the first connecting plate 16 and the second connecting plate 18. A spring 110 is sleeved on the outer wall of the second telescopic rod 19, with one end of the spring 110 connected to the first connecting plate 16 and the other end connected to the second connecting plate 18. Specifically, by providing the second telescopic rod 19 and the spring 110 between the first connecting plate 16 and the second connecting plate 18, it is possible to ensure that the first corrugated pipe 12 can be stably stretched and shortened, and the second telescopic rod 19 can be used to determine the range of stretching and shortening of the first corrugated pipe 12, avoiding excessive stretching and excessive shortening.

[0023] The driving device 20 in this embodiment includes a vertically arranged support plate 21, a bracket for supporting the support plate 21, a telescopic cylinder 23 vertically arranged on the side wall of the support plate 21, a driving plate 24 horizontally arranged at the end of the telescopic rod of the telescopic cylinder 23, and a first connecting rod 25 arranged on the upper side wall of the connecting pipe 14; the first connecting rod 25 is connected to the driving plate 24. Specifically, the telescopic cylinder 23 can pull the driving plate 24, the connecting pipe 14, the first bellows 12 and the second bellows 13, etc., to move. The telescopic cylinder 23 can be hydraulic, electric screw, or pneumatic.

[0024] In this embodiment, the lower end of the feeding pipe 11 is connected to the lower end of the first corrugated pipe 12, and the lower end of the feeding pipe 11 is U-shaped. A support plate 21 is disposed between the feeding pipe 11 and the first corrugated pipe 12, and the lower side wall of the feeding pipe 11 is connected to the support plate 21 via a second connecting rod 112. The side wall of the feeding pipe 11 and the side wall of the support plate 21 are fixedly connected via a connecting block 113. Specifically, the feeding pipe 11 can be fixed using the second connecting rod 112 and the connecting block 113.

[0025] In summary, the high-viscosity liquid filling device for oral liquid production in this embodiment delivers a fixed amount of liquid to the feeding pipe 11 via a pump, and then sequentially through the second corrugated pipe 13, the connecting pipe 14, and the first corrugated pipe 12 before being filled into the bottle. After a single bottle is filled, the driving device 20 drives the connecting pipe 14 to rise. During the rising process of the connecting pipe 14, the first corrugated pipe 12 and the second corrugated pipe 13 are stretched, so that the first corrugated pipe 12 and the second corrugated pipe 13 generate a certain suction force on the liquid, which can draw the liquid suspended at the lower end of the first corrugated pipe 12 into the first corrugated pipe 12. This can effectively prevent the viscous liquid from forming threads at the end of the first corrugated pipe 12 and prevent it from adhering to the outside of the bottle during the movement of the bottle. When the next empty bottle moves directly below the first corrugated pipe 12, the driving device 20 drives the connecting pipe 14 to move downward, so that the first corrugated pipe 12 and the second corrugated pipe 13 retract to their previous positions. This method will not affect the original filling efficiency and filling accuracy, and can effectively prevent the liquid from coming into contact with parts outside the bottle, thus effectively improving the filling quality.

Various modifications and variations can be made to this utility model by those skilled in the art.
