Description

Technical Field

[0001] This application relates to the technical field of dispensing equipment, and particularly to an oral liquid filling equipment. Background Art

[0002] Oral liquid medicine is usually stored in glass bottles and needs to be quantitatively poured using filling equipment. However, the liquid injection head of the existing filling equipment is responsible for two functions: lifting and quantitative liquid discharge, and the realization of these two functions relies on two independent mechanisms, resulting in a relatively complex structure. Summary of the Invention

[0003] The purpose of this application is to provide an oral liquid filling equipment with a simpler structure.

[0004] To achieve the above purpose, this application provides an oral liquid filling equipment, which includes a workbench. A configuration chamber and a medicine bottle conveyor belt are arranged on the workbench. The configuration chamber includes a liquid storage tank fixedly connected to the workbench. A cylinder is fixedly connected to the front of the liquid storage tank through a suspension plate. The movable end of the cylinder is fixedly connected to a quantifier through a linkage plate. The main body of the quantifier is a U-shaped tube, and both ends of the U-shaped tube are vertically downward. The two vertical parts of the U-shaped tube are respectively a liquid suction part and a liquid discharge part. The liquid suction part is communicated with the liquid storage tank through a liquid suction pipe, and a first electric control valve is arranged on the liquid suction pipe. A fixed handle is inserted into the liquid suction part. The fixed handle includes a plug rod fixedly arranged. The upper end of the plug rod is located in the liquid suction part and is fixedly connected to a piston. The lower end of the liquid discharge part is fixedly connected to a liquid injection cone, and a second electric control valve is arranged in the liquid injection cone. When the liquid injection cone descends, it is adapted to inject liquid medicine into the oral liquid bottles on the medicine bottle conveyor belt, synchronously completing the functions of descending and liquid injection, as well as the actions of ascending and liquid suction.

[0005] As a preference, the inner wall of the liquid suction part has a lower limit ring, the piston is located below the lower limit ring, and the connection part of the liquid suction pipe and the liquid suction part is located above the lower limit ring, preventing the piston structure from crossing the through hole on the side wall of the liquid suction part and causing liquid leakage.

[0006] As a preference, the inner wall of the liquid suction part further has an upper limit ring, the upper limit ring is located above the lower limit ring, and the connection part of the liquid suction pipe and the liquid suction part is located between the lower limit ring and the upper limit ring, which is beneficial to improving the structural strength of the entire quantitative tube.

[0007] As a preference, a sliding ring is fixedly connected to the lower end of the liquid suction part, and the plug rod is adapted to pass through the sliding ring to form a sliding pair, which can improve the smoothness of the movement of the quantifier relative to the plug rod.

[0008] As an optimization, the transition between the liquid absorption part and the liquid discharge part is an arc, and the top of the arc is fixedly connected to the lower surface of the linkage plate to obtain the lifting power.

[0009] As an optimization, there are several metering devices. The several metering devices are parallel to each other and are arranged equidistantly on the same horizontal line, and are lifted synchronously, so as to fill multiple dispensing medicine bottles.

[0010] As an optimization, the front bottom of the liquid storage tank has a support plate, and the lower end of the plug rod is fixedly connected to the support plate; a rib plate is fixedly connected between the lower surface of the suspension plate and the front of the liquid storage tank to ensure the connection stability of the air cylinder.

[0011] As an optimization, the medicine bottle conveyor belt is located in front of the workbench, and the liquid injection cone is located above the medicine bottle conveyor belt to ensure that the lower end of the liquid injection cone is always aligned with the bottle mouth of the dispensing medicine bottle.

[0012] Compared with the prior art, the beneficial effects of the present application are as follows:

[0013] (1) By designing the U-shaped metering device structure, the lifting, liquid absorption and liquid discharge actions are realized by using a single drive, so that the lifting motion and the liquid absorption and discharge actions can be linked, effectively reducing the structural complexity of the main functional parts of the filling equipment and reducing the failure rate during the operation of the equipment;

[0014] (2) This design has high working stability, simple and accurate control of quantitative filling. The filling equipment has a reasonable structural design, can fill multiple dispensing bottles at the same time, and has a relatively high working efficiency. Description of the Drawings

[0025] It should be noted that the terms "first", "second", etc. in the description and claims of the present application are used to distinguish similar objects, and do not necessarily need to describe a specific order or sequence.

[0026] The terms "including" and "having" and any variations thereof in the description and claims of the present application are intended to cover non-exclusive inclusion. For example, a process, method, system, product or device that includes a series of steps or units does not necessarily have to be limited to those steps or units clearly listed, but may include other steps or units not clearly listed or inherent to these processes, methods, products or devices.

[0027] Such as Figures 1-7The oral liquid filling equipment shown includes a horizontally arranged workbench 1, on which a configuration chamber 2 and a medicine bottle conveyor belt 8 are provided. The configuration chamber 2 includes a liquid storage tank 201 fixedly connected to the workbench 1 for storing the oral liquid to be sub-packed. A cylinder 3 is fixedly connected to the front of the liquid storage tank 201 through a suspension plate 203. Only the cylinder barrel of the cylinder 3 is fixedly connected to the suspension plate 203. A rib plate 204 is fixedly connected between the lower surface of the suspension plate 203 and the front of the liquid storage tank 201 to ensure the horizontal stability of the suspension plate 203.

[0028] The movable end of the cylinder 3 is fixedly connected to a metering device 5 through a linkage plate 4, which can quantitatively inhale and discharge the oral liquid to be sub-packed. The main part of the metering device 5 is a U-shaped tube 520. The inside of the U-shaped tube 520 is connected and both ends are open. Both ends of the U-shaped tube 520 are vertically downward. Therefore, the U-shaped tube 520 has two vertical parts. The transition between the liquid suction part 521 and the liquid discharge part 525 is an arc, and the top of the arc is fixedly connected to the lower surface of the linkage plate 4. The two vertical parts of the U-shaped tube 520 are respectively the liquid suction part 521 and the liquid discharge part 525. The liquid suction part 521 is close to the liquid storage tank 201, and the liquid discharge part 525 is far from the liquid storage tank 201. Moreover, there are several metering devices 5, and these metering devices 5 are parallel to each other and arranged at equal distances on the same horizontal line, and can simultaneously fill the corresponding number of oral liquid bottles with liquid medicine.

[0029] The liquid suction part 521 is connected to the liquid storage tank 201 through a flexible liquid suction pipe 7. The liquid suction pipe 7 is generally made of food-grade silicone material, taking into account flexibility and safety. The inner wall of the liquid suction part 521 has a lower limit ring 523, and the connection between the liquid suction pipe 7 and the liquid suction part 521 is located above the lower limit ring 523. The inner wall of the liquid suction part 521 usually also has an upper limit ring 524, and the upper limit ring 524 is located above the lower limit ring 523. The connection between the liquid suction pipe 7 and the liquid suction part 521 is actually located between the lower limit ring 523 and the upper limit ring 524. Both the lower limit ring 523 and the upper limit ring 524 have through holes penetrating the upper and lower end faces for the liquid flow to pass through. The cavity formed between the lower limit ring 523 and the upper limit ring 524 is directly connected to the liquid suction pipe 7, and the upper limit ring 524 can further improve the structural strength of the U-shaped tube 520.

[0030] A first electric control valve 503 is provided on the liquid suction pipe 7 for controlling the on-off state of the liquid suction pipe 7. A fixed handle 6 is inserted into the liquid suction part 521. The fixed handle 6 includes a plug rod 601 fixedly arranged. In fact, a support plate 202 is provided at the front bottom of the liquid storage tank 201, and the lower end of the plug rod 601 is fixedly connected to the upper surface of the support plate 202. A coaxial slip ring 522 is also fixedly connected to the lower end of the liquid suction part 521. The plug rod 601 is adapted to pass through the slip ring 522 to form a sliding pair, which can effectively improve the stability of the movement of the liquid suction part 521 relative to the fixed handle 6. The upper end of the plug rod 601 is located inside the liquid suction part 521 and is fixedly connected with a piston 602. The piston 602 is made of medical rubber material and can be used for a long time without affecting the quality of oral liquid. The piston 602 is located below the lower limit ring 523. The slip ring 522 and the lower limit ring 523 limit the upper and lower extreme positions of the piston 602, so that when the piston 602 reciprocates up and down once, the quantifier 5 can inhale and discharge a standard amount of oral liquid. The lower limit ring 523 can prevent the piston 602 from crossing the connection part of the liquid suction pipe 7 and the liquid suction part 521, avoiding the pollution and waste caused by the oral liquid flowing into the space below the piston 602.

[0031] The lower end of the liquid discharge part 525 is fixedly connected with a liquid injection cone 501. The upper end of the liquid injection cone 501 is large and the lower end is small, and the lower end can be inserted into the mouth of the oral liquid bottle. A second electric control valve 504 is arranged in the liquid injection cone 501 for controlling the on-off of the liquid injection cone 501. When the liquid injection cone 501 descends, it can inject the liquid medicine into the oral liquid bottle on the medicine bottle conveyor belt 8. The medicine bottle conveyor belt 8 is located in the front of the workbench 1 and is restricted by the rollers rotatably connected to the workbench 1. The liquid injection cone 501 is located above the medicine bottle conveyor belt 8. The oral liquid bottle moves horizontally under the drive of the medicine bottle conveyor belt 8 and will stop briefly during filling and capping.

[0032] Working principle: The first electronic control valve 503 and the second electronic control valve 504 are precisely opened and closed under the control of an industrial computer. The cylinder 3 is indirectly controlled by the industrial computer through a pneumatic system. Before use, the equipment is initialized. The second electronic control valve 504 is first closed, and the first electronic control valve 503 is opened. The cylinder 3 drives the U-shaped tube 520 to move upward, and the oral liquid to be dispensed is sucked into the U-shaped tube 520 through the liquid suction tube 7. Subsequently, the first electronic control valve 503 is closed, and the second electronic control valve 504 is opened. The cylinder 3 drives the U-shaped tube 520 to move downward, and the air in the U-shaped tube 520 is discharged. This process is repeated multiple times until all the air in the U-shaped tube 520 is discharged. The space between the piston 602 and the injection cone 501 is filled with the oral liquid medicine to be dispensed. At this time, the first electronic control valve 503 is closed, and the second electronic control valve 504 is opened. The cylinder 3 moves again, causing the piston 602 to move from the contact position with the slip ring 522 to the contact position with the lower limit ring 523. The injection cone 501 synchronously moves downward and inserts into the mouth of the oral liquid bottle, and quantitatively injects the oral liquid medicine into the stationary oral liquid dispensing bottle. Immediately afterwards, the second electronic control valve 504 is closed, and the first electronic control valve 503 is opened. The cylinder 3 drives the U-shaped tube 520 to move upward, causing the piston 602 to move from the contact position with the lower limit ring 523 to the contact position with the slip ring 522, and allowing the quantifier 5 to suck in an oral liquid with a capacity equal to that of a standard dispensing bottle again. The medicine bottle conveyor belt 8 moves once to move the filled dispensing bottle to the next station and move the unfilled new dispensing bottle to the position below the parallel injection cone 501. Repeating this process can efficiently fill the oral liquid.

Those skilled in the art of this industry should understand that the present application is not limited by the above embodiments. What is described in the above embodiments and the specification is only the principle of the present application.
