Description

Technical Field

[0001] This utility model relates to the field of liquid filling technology, specifically to a liquid filling device. Background Technology

[0002] In industrial production such as food, beverage, daily chemical, and pharmaceutical, automated filling of liquid products is a crucial step in the packaging process. Liquid filling equipment is used to fill a fixed quantity of liquid materials (such as water, oil, emulsions, detergents, and pharmaceutical solutions) into containers such as bottles, barrels, and cans, requiring features such as high filling accuracy, stable operation, cleanliness and hygiene, and ease of operation.

[0003] Current filling equipment cannot adjust the flow rate according to demand, which can easily lead to underfilling or overflow. Furthermore, liquid may continue to flow even before the container is in place or during the replacement process, resulting in waste and leakage. This can cause liquid to drip onto the filling platform, increasing the cleaning burden. Therefore, we propose a liquid filling device. Utility Model Content

Detailed Implementation

[0023] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0024] Example: Figures 1-5 As shown, this utility model discloses a liquid filling device, including a support frame 1. A liquid storage tank 2 is fixedly installed on the upper end of the support frame 1. A funnel tank 3 is fixedly connected to the lower end of the liquid storage tank 2. An L-shaped conveying pipe 4 is fixedly connected to the output end of the funnel tank 3. An adjusting shell 5 is fixedly installed on the outer periphery of the L-shaped conveying pipe 4. A placement plate 6 is fixedly connected to the inside of one side of the support frame 1. A cavity 7 is opened inside the adjusting shell 5. A lead screw 8 is rotatably connected to the lower end of the cavity 7. A threaded block 9 is threadedly connected to the outer periphery of the lead screw 8. A piston 10 is fixedly connected to one side of the threaded block 9.

[0025] The L-shaped conveying pipe 4 is internally fixedly connected with a retaining ring 11, and the outer periphery of the piston 10 passes through the L-shaped conveying pipe 4 and engages with the retaining ring 11. One end of the lead screw 8 is fixedly connected with a small gear 12, which passes through the outer periphery of the piston 10 through the L-shaped conveying pipe 4 and engages with the retaining ring 11, thus playing a guiding and limiting role and preventing the piston from shifting or falling off.

[0026] The adjustment housing 5 has a geared motor 13 fixedly installed on one end of its outer periphery. The adjustment housing 5 has a large gear 14 rotatably connected to one end of its inner periphery. The output end of the geared motor 13 passes through the adjustment housing 5 and is connected to the large gear 14 via a coupling. The outer periphery of the large gear 14 is meshed with the small gear 12. When the geared motor 13 is started, it drives the large gear 14 to rotate, which in turn drives the small gear 12 and the lead screw 8 to rotate. This causes the threaded block 9 to drive the piston 10 to move back and forth in the L-shaped conveying pipe 4, thereby realizing continuous adjustment of the filling flow rate.

[0027] The lower end of the L-shaped conveying pipe 4 is threaded with a threaded cap 15. The lower end surface of the threaded cap 15 is provided with several water outlet holes 16. The lower end of the threaded cap 15 is rotatably connected to a grooved wheel 17. The surface of the grooved wheel 17 is provided with a through hole 20, and the through hole 20 corresponds to the water outlet hole 16. The through hole 20 can periodically align with or stagger the water outlet hole 16, thereby realizing the "opening" and "closing" of liquid discharge.

[0028] A micro motor 18 is installed on one side of the threaded cap 15. The output end of the micro motor 18 is connected to a semi-grooved wheel 19, and the outer circumference of the semi-grooved wheel 19 is engaged with the grooved wheel 17. The engagement of the semi-grooved wheel 19 and the grooved wheel 17 forms a typical intermittent grooved wheel mechanism. When the micro motor 18 drives the semi-grooved wheel 19 to rotate continuously, it drives the grooved wheel 17 to rotate periodically and intermittently, so that the through hole 20 is aligned with the water outlet hole 16 at regular intervals, realizing intermittent quantitative liquid dispensing and effectively preventing dripping after filling.

[0029] The upper end of the storage tank 2 is fixedly equipped with a servo motor 21. The output end of the servo motor 21 is connected to a rotating column 22 via a coupling. Several stirring rods 23 are fixedly connected to the outer periphery of the rotating column 22. The lower end of the rotating column 22 is fixedly connected to a scraper 25 via a connecting rod 24. The scraper 25 is in contact with the inner wall of the storage tank 2. By rotating synchronously with the stirring rods 23, the scraper 25 can scrape off the viscous material adhering to the tank wall, ensuring uniform liquid flow and improving filling consistency.

[0030] The placement plate 6 has a fixedly connected placement tray 26. A water inlet trough 27 is formed on the outer periphery of the placement tray 26, with an inclined bottom. A connecting pipe 28 is connected to one side of the water inlet trough 27. A collection box 29 is slidably connected to the lower end of one side of the support frame 1. An inlet pipe is provided at the upper end of the liquid storage tank 2. The placement tray 26 is used to hold bottles, cans, and other containers to be filled. The inclined bottom of the water inlet trough 27 on the outer periphery of the placement tray 26 facilitates the collection of overflowing or dripping liquid.

[0031] Working Principle: In use, the liquid to be filled is first injected into the storage tank 2 through the inlet pipe. The servo motor 21 is started, driving the rotating column 22, stirring rod 23, and scraper 25 to rotate, stirring the liquid in the tank and removing residue from the tank walls, ensuring uniform and stable material distribution. Based on the required filling volume, the reduction motor 13 is started, driving the large gear 14 to mesh with the small gear 12, rotating the lead screw 8, causing the threaded block 9 to push the piston 10 within the L-shaped delivery pipe 4, adjusting the flow area between it and the outlet hole 16, thereby setting a suitable liquid flow rate. The container to be filled is placed on the placement tray 26, and the micro motor 18 is started, driving the semi-grooved wheel 19 to rotate, causing the grooved wheel 17 to move intermittently. When the through hole 20 on the grooved wheel 17 is aligned with the water outlet hole 16 on the threaded cap 15, the liquid flows out from the storage tank 2 through the funnel tank 3 and the L-shaped conveying pipe 4 and enters the container; when the through hole 20 is misaligned with the water outlet hole 16, the liquid outlet channel is closed and the liquid outlet stops, realizing the intermittent operation of "one filling at a time". During the filling process, if a small amount of liquid overflows or drips, it will flow into the water inlet trough 27 along the placement tray 26, and then be discharged into the sliding collection box 29 through the connecting pipe 28 for centralized recycling, keeping the working environment clean.
