AI Technical Summary
When traditional filling equipment fills oral fluids, high-speed fluids are prone to sputtering or stir up foam in the bottle, resulting in reduced filling efficiency. Especially for drugs that need to avoid foam, existing equipment is difficult to find a balance between efficient filling and anti-sputtering.
The circulating filling assembly with multiple sets of filling heads is adopted to extend the relative rest time between the filling head and the bottle opening through synchronous movement and clamping, ensuring a stable filling environment and avoiding sputtering and foaming.
Efficient filling under slow infusion is achieved, filling efficiency is improved, and oral liquid sputtering and foam generation are avoided, ensuring consistency in filling quality.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of filling mechanisms, in particular to a filling mechanism for an oral liquid production line. Background Technique
[0002] The oral liquid filling mechanism is used to accurately and automatically fill liquid products into bottles or containers. Common types include piston filling machines, pump filling machines, gravity filling machines, and metering filling machines. The oral liquid filling mechanism can improve production efficiency, ensure filling accuracy and consistency. Automated operation reduces manual intervention, lowers production costs, and increases production speed at the same time. The equipment can accurately control the filling volume to ensure that the liquid dose in each bottle is consistent and meets quality standards.
[0003] The filling mechanism is a key tool in the large-scale production of oral liquids, but there are still certain problems: Traditional filling equipment improves filling efficiency by increasing the liquid perfusion speed, which results in a short perfusion time between the filling head and a single oral liquid bottle. High-speed fluid is likely to splash out from the mouth of the oral liquid bottle or generate foam inside the bottle. For oral liquid drugs that are prone to foaming but need to avoid it, when using such filling equipment, only the filling time can be extended, which leads to a reduction in filling efficiency. Therefore, in view of the above current situation, there is an urgent need to develop a filling mechanism for an oral liquid production line to overcome the deficiencies in current practical applications and meet current requirements. Content of the Utility Model
[0004] The purpose of the utility model is to provide a filling mechanism for an oral liquid production line to solve the problems raised in the above background technique.
[0005] To achieve the above purpose, the utility model provides the following technical solution: A filling mechanism for an oral liquid production line includes a base, a conveyor belt, and a filling component. The conveyor belt is horizontally installed at the middle position on the top of the base, and the filling component is horizontally arranged on the top of the conveyor belt and is fixedly connected to the base.
[0006] The filling component includes a mounting shell, a cylinder, a drive belt a, a drive belt b, a transmission box, and a motor. The mounting shell is fixedly connected to the base by screws. The motor is vertically installed at the top edge of the mounting shell. The drive belt a is vertically installed at the middle position inside the mounting shell. Two groups of drive belts b are horizontally installed at the bottom edge positions inside the mounting shell. The cylinder is vertically installed at the top edge of the mounting shell. A transmission box is installed inside the mounting shell. The drive belt a and the drive belt b are drivenly connected to the motor through the transmission box. The drive wheels at both ends of the drive belt a and the drive belt b are respectively in transmission connection with a transmission shaft b and a transmission shaft a.
[0007] Preferably, equidistant filling heads are installed around the edge of the conveyor belt a. Specifically, the filling heads are used to fill the oral liquid bottles. Since the filling heads and the oral liquid bottles are in a synchronous motion state, the filling heads can maintain a longer relative static time with a single oral liquid bottle, providing a stable filling environment.
[0008] Preferably, a belt is nested on the edge of the conveyor belt b. A number of equidistant card slots are opened on the outer wall of the belt. Specifically, there are two sets of conveyor belt b and the belt, which are distributed relatively. Through the cooperation of the two sets of relatively distributed card slots, the oral liquid bottles can be clamped and fixed.
[0009] Preferably, a drive shaft a and a drive shaft b are provided inside the transmission case. The drive shaft a vertically penetrates the top and bottom of the transmission case and is rotationally and slidably connected to the transmission case. The drive shaft b horizontally penetrates and is arranged on one side of the transmission case and is rotationally connected to the transmission case. A bevel gear a is sleeved on the middle section of the drive shaft a, and a bevel gear b is nested at the end of the drive shaft b. The bevel gear a and the bevel gear b have the same structure and are meshed. Specifically, when the drive shaft b moves up and down, it will drive the transmission case to move up and down synchronously and keep the bevel gear a and the bevel gear b meshed.
[0010] Preferably, a keyway is opened on the middle section of the drive shaft a. The bevel gear a is adapted to the keyway of the drive shaft a, and the bevel gear a and the drive shaft a are axially slidably connected through the keyway. Specifically, the keyway can enable the bevel gear a to still be adapted to the drive shaft a after lifting.
[0011] Preferably, the end of the telescopic shaft of the cylinder is rotationally connected to the drive shaft a through a spherical plain bearing. Specifically, the spherical plain bearing is a fish-eye joint. The cylinder cooperates with the drive shaft b to drive the conveyor belt a to move up and down, so as to adjust the distance between the filling head and the bottom oral liquid bottle.
[0012] Compared with the prior art, the present utility model provides a filling mechanism for an oral liquid production line, which has the following beneficial effects:
[0013] It adopts a conveyor belt a and multiple groups of filling heads to form a circulating filling assembly, which can fill multiple oral liquid bottles simultaneously, improve the filling efficiency, and while ensuring high efficiency, effectively extend the filling time between the filling head and a single oral liquid bottle, enabling it to maintain overall high-efficiency filling at a relatively slow perfusion speed of the oral liquid, and avoiding the oral liquid splashing out of the oral liquid bottle or generating foam in the oral liquid bottle.

[0022] Embodiment:
[0023] Please refer to Figures 1 - 4, the present utility model provides a technical solution: a filling mechanism for an oral liquid production line, including a base 10, a conveyor belt 20 and a filling assembly 30. The conveyor belt 20 is horizontally installed at the middle position on the top of the base 10. The filling assembly 30 is horizontally arranged on the top of the conveyor belt 20 and is fixedly connected to the base 10.
[0024] The filling assembly 30 includes a mounting shell 301, a cylinder 302, a drive belt a 303, a drive belt b 304, a transmission box 305 and a motor 306. The mounting shell 301 is fixedly connected to the base 10 by screws. The motor 306 is vertically installed at the top edge of the mounting shell 301. The drive belt a 303 is vertically installed at the middle position inside the mounting shell 301. Two groups of drive belts b 304 are horizontally installed at the inner bottom edge position of the mounting shell 301. The cylinder 302 is vertically installed at the top edge of the mounting shell 301. A transmission box 305 is installed inside the mounting shell 301. The drive belt a 303 and the drive belt b 304 are drivenly connected to the motor 306 through the transmission box 305. The drive wheels at both ends of the drive belt a 303 and the drive belt b 304 are respectively in transmission connection with a transmission shaft b 3054 and a transmission shaft a 3053. The outer diameters and lengths of the drive belt a 303 and the drive belt b 304 are the same.
[0025] Preferably, equidistant filling heads 3031 are installed around the edge of the drive belt a 303. Specifically, the filling heads 3031 are used to perform filling operations on oral liquid bottles. Since the filling heads 3031 and the oral liquid bottles are in a synchronous movement state, the filling heads 3031 can maintain a longer relative static time with a single oral liquid bottle, providing a stable filling environment.
[0026] Preferably, a belt 3041 is nested on the edge of the drive belt b 304. A number of equidistant card slots 3042 are opened on the outer wall of the belt 3041. Specifically, there are two groups of the drive belt b 304 and the belt 3041, which are distributed relatively. Through the cooperation of the two relatively distributed card slots 3042, the oral liquid bottles can be clamped and fixed.
[0027] Preferably, a transmission shaft a 3053 and a transmission shaft b 3054 are provided inside the transmission box 305. The transmission shaft a 3053 vertically penetrates the top and bottom ends of the transmission box 305 and is rotationally and slidably connected to the transmission box 305. The transmission shaft b 3054 is horizontally penetrated and arranged on one side of the transmission box 305 and is rotationally connected to the transmission box 305. A bevel gear a 3051 is sleeved on the middle section of the transmission shaft a 3053. A bevel gear b 3052 is nested at the end of the transmission shaft b 3054. The bevel gear a 3051 and the bevel gear b 3052 have the same structure and are meshed. Specifically, when the transmission shaft a 3053 moves up and down, it will drive the transmission box 305 to move up and down synchronously and keep the bevel gear a 3051 and the bevel gear b 3052 meshed.
[0028] Preferably, a keyway 3055 is provided in the middle section of the transmission shaft a3053. The bevel gear a3051 is adapted to the keyway 3055 of the transmission shaft a3053, and the bevel gear a3051 is slidably connected to the transmission shaft a3053 along the axial direction through the keyway 3055. Specifically, by providing the keyway 3055, the bevel gear a3051 can still be adapted to the transmission shaft a3053 after lifting.
[0029] Preferably, the end of the telescopic shaft of the air cylinder 302 is rotatably connected to the transmission shaft a3053 through a spherical plain bearing. Specifically, the spherical plain bearing is a rod end bearing. The air cylinder 302 cooperates with the transmission shaft b3054 to drive the conveyor belt a303 to lift, so as to adjust the distance between the filling head 3031 and the bottom oral liquid bottle.
[0030] Working principle: The empty oral liquid bottles are sequentially placed at one end of the conveyor belt 20. During the conveying process, they will pass through the filling assembly 30. When the empty oral liquid bottles approach the conveyor belt b304, they will be clamped and fixed by the belts 3041 on both sides through the card slots 3042 and continue to be conveyed. At the same time, the filling head 3031 will rotate to be vertically aligned with the empty oral liquid bottle and penetrate into it. At this time, the external pipeline is connected to the filling head 3031 for oral liquid filling. By continuously repeating the above process, continuous batch filling of empty oral liquid bottles is realized. It should be noted here that the filling assembly 30 is driven by an external motor to rotate the transmission shaft a3053. Under the mutual cooperation of the bevel gear a3051 and the bevel gear b3052, the transmission shaft b3054 is driven to rotate, so as to realize the synchronous movement of the conveyor belt a303 and the conveyor belt b304.
[0031] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variation thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements not only includes those elements, but also includes other elements not expressly listed, or elements inherent to such process, method, article or device.
