Description

Technical Field

[0001] This utility model relates to the field of drop filling equipment technology, and in particular to a device for online precise metering of drop filling equipment. Background Technology

[0002] Currently, drop filling equipment is widely used in food, pharmaceutical, and chemical industries. One of its core requirements is to achieve accurate online metering during the filling process to ensure that the dosage of each bottle of drops meets the standards.

[0003] However, existing online precision metering devices in drop filling equipment filter the liquid during use. Most existing filter structures are fixed installations, requiring the disassembly of numerous pipelines for replacement. This process is complex, time-consuming, and severely impacts the continuous operation of the production line, shortens the lifespan of filter components, and further increases maintenance costs. To address these technical problems, this utility model provides an online precision metering device for drop filling equipment. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a device for online precise metering of drop filling equipment.

[0005] This utility model is achieved using the following technical solution: a device for online precise metering of a drop filling equipment, comprising a conveying assembly for conveying drop bottles, a filling assembly for filling drop bottles on one side of the conveying assembly, a liquid inlet pipe fixedly connected to the liquid inlet of the filling assembly, a precise metering assembly for controlling the precise metering of the filling assembly at one end of the liquid inlet pipe, a filter assembly for filtering the liquid being filled by the filling assembly on the liquid inlet pipe, a replacement assembly for quickly replacing the filter assembly on the filter assembly, an installation port for easy installation of the filter assembly on the liquid inlet pipe, the filter assembly comprising a filter tube disposed inside the installation port, a filter plate disposed inside the filter tube, a limiting ring disposed on one side of the filter plate, and the cylindrical surface of the limiting ring being fixedly installed to the inner wall of the filter tube.

[0006] Through the above technical solutions, the conveying component can stably transport the dropper bottles to be filled to the bottom of the filling component, ensuring accurate filling position; the precision metering component is connected to the filling component through the liquid inlet pipe, and can monitor and control the liquid flow rate entering the filling component in real time to achieve accurate metering; the filter tube is installed on the liquid inlet pipe through the installation port, and its internal filter plate can intercept impurities in the liquid, preventing impurities from entering the filling component and clogging the channel or affecting the metering accuracy; the limiting ring can fix the filter plate to prevent the filter plate from shifting under liquid impact and ensure filtration stability.

[0007] As a further improvement to the above solution, a cleaning ring is fixedly installed on the other side of the filter plate. The inner ring surface of the cleaning ring is inclined, and the outer ring surface of the cleaning ring is in contact with the inner wall of the filter tube.

[0008] Through the above technical solution, the close fit design between the cleaning ring and the inner wall of the filter tube can slightly scrape the inner wall of the filter tube during the removal of the cleaning ring, reduce the adhesion of impurities on the tube wall, help keep the inside of the filter tube clean, and extend the maintenance cycle of the filter assembly.

[0009] As a further improvement to the above solution, a plurality of connecting rods arranged in a ring array are fixedly installed on one side of the cleaning ring, and a blocking ring for preventing the flow of filtered debris is fixedly installed at one end of the plurality of connecting rods, and the inner ring surface of the blocking ring is inclined.

[0010] Through the above technical solution, the connecting rod can fix the position of the blocking ring, so that the blocking ring is located at the liquid inflow end of the filter plate; the inclined inner ring surface can guide the liquid to the filter plate and also initially block larger particles of impurities, preventing large particles of impurities from directly impacting the filter plate and causing blockage. At the same time, it can temporarily intercept impurities, reduce the rapid accumulation of impurities on the surface of the filter plate, and improve filtration efficiency.

[0011] As a further improvement to the above solution, the replacement component includes two sealing plates that are slidably sleeved on the filter tube. Both sealing plates are semi-circular arc-shaped and are fitted together to form a complete cylinder. The two connection points between the filter tube and the installation port are located inside the cylinder formed by the two sealing plates.

[0012] With the above technical solution, two semi-circular sealing plates can be slidably fitted onto the filter tube, forming a complete cylinder after fitting, which encloses the connection between the filter tube and the installation port, effectively preventing liquid leakage from the connection; at the same time, the sliding design of the sealing plates facilitates subsequent disassembly, providing a basis for the rapid replacement of the filter assembly.

[0013] As a further improvement to the above solution, clamps are slidably fitted on both ends of the two sealing plates, and both clamps are located at the connection between the adjacent filter tube and the installation port.

[0014] With the above technical solution, the clamps are fitted on both ends of the sealing plate, which can further strengthen the fit between the sealing plate and the filter pipe and the installation port, and enhance the sealing effect; and the sliding characteristics of the clamps make it easy to quickly disassemble when replacing the filter components without having to disassemble the pipeline, thus improving the convenience of replacement.

[0015] As a further improvement to the above solution, two fixing plates for controlling the opening and closing of the clamps are fixedly installed on one side of each clamp. Each clamp has a bolt on one side, and the bottom ends of the two bolts are threaded downwards through the adjacent fixing plates and fitted with nuts.

[0016] Through the above technical solution, the fixing plate provides an installation carrier for the bolts and nuts. By tightening the bolts and nuts, the clamp can be contracted, so that the clamp fits tightly against the sealing plate. When disassembling, simply loosen the bolts and nuts to open the clamp. The operation is simple, further shortening the replacement time of the filter components and ensuring the continuous operation of the production line.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model achieves graded filtration and auxiliary cleaning of the filling liquid by setting up a filter assembly, including a filter tube, filter plate, limiting ring, cleaning ring, connecting rod, and blocking ring. It can effectively intercept impurities and prevent clogging of the filling assembly, reduce impurity accumulation, extend the life of the filter components, and ensure the metering accuracy of the precision metering assembly.

[0020] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0021] Please combine Figures 1-5This embodiment of a device for online precise metering of a drop filling equipment includes a conveying assembly 1 for conveying drop bottles, a filling assembly 2 for filling drop bottles on one side of the conveying assembly 1, a liquid inlet pipe 3 fixedly connected to the liquid inlet of the filling assembly 2, a precise metering assembly 4 for controlling the precise metering of the filling of the filling assembly 2 fixedly connected to one end of the liquid inlet pipe 3, a filter assembly for filtering the liquid being filled by the filling assembly 2 on the liquid inlet pipe 3, and a replacement assembly for quickly replacing the filter assembly on the filter assembly.

[0022] The inlet pipe 3 has an installation port 7 for easy installation of the filter assembly. The filter assembly includes a filter pipe 501 disposed inside the installation port 7. The filter pipe 501 has a filter plate 502 disposed inside it. A limiting ring 503 is provided on one side of the filter plate 502. The cylindrical surface of the limiting ring 503 is fixedly installed to the inner wall of the filter pipe 501.

[0023] The conveying assembly 1 can stably convey the dropper bottle to be filled to the bottom of the filling assembly 2, ensuring accurate filling position; the precision metering assembly 4 is connected to the filling assembly 2 through the liquid inlet pipe 3, and can monitor and control the liquid flow rate entering the filling assembly 2 in real time to achieve accurate metering; the filter tube 501 is installed on the liquid inlet pipe 3 through the installation port 7, and the filter plate 502 inside it can intercept impurities in the liquid, preventing impurities from entering the filling assembly 2 and clogging the channel or affecting the metering accuracy; the limiting ring 503 can fix the filter plate 502 to prevent the filter plate 502 from being displaced under liquid impact, ensuring filtration stability.

[0024] A cleaning ring 8 is fixedly installed on the other side of the filter plate 502. The inner ring surface of the cleaning ring 8 is inclined, and the outer ring surface of the cleaning ring 8 is in contact with the inner wall of the filter tube 501.

[0025] The close fit design between the cleaning ring 8 and the inner wall of the filter tube 501 allows for slight scraping of the inner wall of the filter tube 501 during the removal of the cleaning ring 8, reducing the adhesion of impurities to the tube wall, helping to keep the inside of the filter tube 501 clean, and extending the maintenance cycle of the filter assembly.

[0026] A plurality of connecting rods 9 arranged in a ring array are fixedly installed on one side of the cleaning ring 8. A blocking ring 10 for preventing the flow of filtered debris is fixedly installed at one end of the plurality of connecting rods 9. The inner ring surface of the blocking ring 10 is inclined.

[0027] The connecting rod 9 can fix the position of the blocking ring 10, so that the blocking ring 10 is located at the liquid inflow end of the filter plate 502; the inclined inner ring surface can guide the liquid to flow to the filter plate 502, and can also initially block larger particles of impurities, preventing large particles of impurities from directly impacting the filter plate 502 and causing blockage. At the same time, it can temporarily intercept impurities, reduce the rapid accumulation of impurities on the surface of the filter plate 502, and improve filtration efficiency.

[0028] The replacement component includes two sealing plates 601 that are slidably fitted onto the filter tube 501. Both sealing plates 601 are semi-circular arc-shaped and fit together to form a complete cylinder. The two connection points between the filter tube 501 and the mounting port 7 are located inside the cylinder formed by the two sealing plates 601.

[0029] Two semi-circular sealing plates 601 can slide onto the filter tube 501, forming a complete cylinder after fitting, which encloses the connection between the filter tube 501 and the mounting port 7, effectively preventing liquid leakage from the connection. At the same time, the sliding design of the sealing plates 601 facilitates subsequent disassembly, providing a basis for quick replacement of the filter assembly.

[0030] Both ends of the two sealing plates 601 are slidably fitted with clamps 602, and both clamps 602 are located at the connection between the adjacent filter tube 501 and the installation port 7.

[0031] The clamp 602 is fitted onto both ends of the sealing plate 601, which can further strengthen the fit between the sealing plate 601 and the filter tube 501 and the mounting port 7, and enhance the sealing effect; and the sliding characteristics of the clamp 602 make it easy to quickly disassemble when replacing the filter assembly without having to disassemble the pipeline, thus improving the convenience of replacement.

[0032] Two fixing plates 11 for controlling the opening and closing of the clamps 602 are fixedly installed on one side of each clamp 602. Each clamp 602 has a bolt 12 on one side. The bottom ends of the two bolts 12 are threaded downward through the adjacent fixing plates 11 and fitted with nuts.

[0033] The fixing plate 11 provides an installation carrier for the bolts 12 and nuts. By tightening the bolts 12 and nuts, the clamp 602 can be contracted, so that the clamp 602 fits tightly against the sealing plate 601. When disassembling, simply loosen the bolts 12 and nuts to open the clamp 602. The operation is simple, further shortening the replacement time of the filter components and ensuring the continuous operation of the production line.

[0034] The implementation principle of the device for online precise metering of a drop filling equipment in this application embodiment is as follows: First, the conveying component 1 is started, and the conveying component 1 drives the drop bottle to be filled to move towards the filling component 2 until the drop bottle reaches the bottom of the filling component 2 and is positioned. Subsequently, the filling liquid flows from the precision metering component 4 to the liquid inlet pipe 3. The liquid first contacts the blocking ring 10 inside the filter tube 501. The inclined inner ring surface of the blocking ring 10 guides the liquid to flow to the filter plate 502. Next, after passing through the blocking ring 10, the liquid flows through the gap between the connecting rods 9 to the cleaning ring 8, and the inclined inner ring surface of the cleaning ring 8 further guides the liquid to flow smoothly to the filter plate 502. Finally, the liquid passes through the filter plate 502, which intercepts small impurities in the liquid. The filtered clean liquid flows into the filling assembly 2 through the liquid inlet pipe 3. During this process, the limiting ring 503 always fixes the position of the filter plate 502 to prevent the filter plate 502 from shifting under the impact of the liquid.

[0035] When the clean liquid enters the filling assembly 2, the precision metering assembly 4 monitors the liquid flow rate in the inlet pipe 3 in real time and sends a control signal to the filling assembly 2 according to the preset drop dosage. After receiving the signal, the filling component 2 adjusts the liquid dispensing volume and injects a fixed amount of liquid into the positioned dropper bottle below, completing the filling of a single dropper bottle. After filling is completed, the conveying component 1 carries the filled dropper bottle away from the filling component 2, and at the same time conveys the next dropper bottle to be filled to the bottom of the filling component 2, repeating the above filtration and filling process.

[0036] When the filter components become clogged or reach their maintenance cycle, first, stop the equipment operation and close the liquid passage between the precision metering component 4 and the liquid inlet pipe 3 to prevent liquid leakage. Subsequently, use tools to loosen the bolts 12 and nuts on the clamp 602. The threaded engagement between the bolts 12 and nuts gradually loosens, causing the two fixing plates 11 to move away from each other. The fixing plates 11 then cause the clamp 602 to open. Next, slide the open clamp 602 off from both ends of the sealing plate 601, and then slide the two semi-circular sealing plates 601 off the filter tube 501 to both sides to expose the connection between the filter tube 501 and the mounting port 7. Next, remove the filter tube 501 from the installation port 7 of the liquid inlet tube 3 and replace it with a new filter tube 501. The new filter tube 501 is pre-installed with a filter plate 502, a limiting ring 503, a cleaning ring 8, a connecting rod 9, and a blocking ring 10. Finally, install the new filter tube 501 into the installation port 7, slide the two sealing plates 601 onto the filter tube 501 in sequence and fit them together to form a complete cylinder, then slide the clamp 602 onto both ends of the sealing plate 601, align the connection between the filter tube 501 and the installation port 7, tighten the bolts 12 and nuts, so that the clamp 602 shrinks and presses the sealing plate 601, ensuring that the connection is sealed and leak-free. After the replacement is completed, the equipment can be restarted to resume operation.

[0037] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
