[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example 1:

[0024] Please see Figures 1-4 This utility model provides a quantitative filling equipment for a detergent production line, including a conveyor frame 1, a bracket 11 fixedly installed on the top of the conveyor frame 1, a storage tank 3 installed on the bracket 11, the output end of the storage tank 3 is connected to a piston tank 2 through an inlet pipe 21, the piston tank 2 is connected to an outlet pipe 22, the end of the outlet pipe 22 away from the piston tank 2 is connected to a filling nozzle, a sealing plug 26 is provided inside the piston tank 2, one side of the sealing plug 26 is connected to a pull rod 261, the pull rod 261 is connected to the output end of an electric telescopic rod 24 through a connecting plate 25, the electric telescopic rod 24 is installed on the outside of the piston tank 2, and a one-way pipe 23 is provided on both the inlet pipe 21 and the outlet pipe 22;

[0025] Both ends of the inlet pipe 21 are connected to the piston tank 2 and the storage tank 3 respectively via flanges, and both ends of the outlet pipe 22 are connected to the piston tank 2 and the filling nozzle respectively via flanges.

[0026] The one-way tube 23 includes an inlet 231, the diameter of which gradually decreases from the outer end to the inner end. A limit frame 233 is fixedly installed in the one-way tube 23. A guide rod 234 is slidably arranged in the limit frame 233. One end of the guide rod 234 is connected to a sealing ball 232. The sealing ball 232 is connected to the limit frame 233 through a spring 235.

[0027] The inlet 231 inside the one-way tube 23 on the inlet pipe 21 is located near the end of the storage tank 3, and the inlet 231 inside the one-way tube 23 on the outlet pipe 22 is located near the end of the piston tank 2.

[0028] Specifically, the electric telescopic rod 24 is activated and extended, driving the pull rod 261 via the connecting plate 25. The pull rod 261 pulls the sealing plug 26 outward within the piston tank 2, creating a negative pressure inside the piston tank 2. At this time, the sealing ball 232 inside the one-way tube 23 on the inlet pipe 21 overcomes the spring force of the spring 235 under the negative pressure, driving the guide rod 234 to move towards the limit frame 233, opening the inlet port 231, and allowing detergent to flow from the storage tank 3 into the piston tank 2 through the inlet pipe 21. Meanwhile, the sealing ball 232 inside the one-way tube 23 on the outlet pipe 22 tightly blocks the inlet port 231 under the action of the spring 235 and external pressure, preventing detergent backflow.

[0029] When the electric telescopic rod 24 retracts, it pushes the pull rod 261 and the sealing plug 26 to move inward inside the piston tank 2, increasing the pressure inside the piston tank 2. Under the action of pressure and the elastic force of the spring 235, the sealing ball 232 in the one-way tube 23 on the inlet pipe 21 blocks the inlet port 231, preventing the detergent from flowing back into the storage tank 3. Under the action of pressure, the sealing ball 232 in the one-way tube 23 on the outlet pipe 22 overcomes the elastic force of the spring 235, and the inlet port 231 opens. The detergent in the piston tank 2 is then poured into the packaging container through the outlet pipe 22 and the filling nozzle.

[0030] By precisely controlling the extension and retraction stroke of the electric telescopic rod 24, the moving distance of the sealing plug 26 in the piston tank 2 can be determined, thereby controlling the volume of liquid suction and filling each time, realizing quantitative filling. The one-way tube 23 ensures that the detergent can only flow in one direction, effectively preventing the backflow and leakage of detergent, avoiding the problem of inaccurate filling volume caused by backflow, and further improving the accuracy of quantitative filling.

[0031] Both ends of the inlet pipe 21 and the outlet pipe 22 are connected by flanges, which facilitates disassembly and installation. When a component fails, it can be quickly replaced, reducing the maintenance time and cost of the equipment.

[0032] Even if components such as piston can 2 and sealing plug 26 wear out due to long-term use, the sealing ball 232 inside the one-way tube 23 can still maintain a good seal under the action of spring 235, reducing inaccurate metering and material waste caused by leakage.

[0033] Furthermore, to improve the efficiency of removing residual detergent from the inner wall of storage tank 3, please refer to... Figures 1-4 The top of the storage tank 3 is bolted to a top cover 31, and a motor 32 is mounted on the top cover 31. The output end of the motor 32 is connected to a rotating shaft 33 via a flange. The rotating shaft 33 is connected to a connecting piece 35 via a first connecting bracket 34. The connecting piece 35 is fixedly mounted on one side of the first scraper 351. The rotating shaft 33 is connected to a second scraper 37 via a second connecting bracket 36.

[0034] Both the first scraper 351 and the second scraper 37 are attached to the inner wall of the liquid storage tank 3, and the first scraper 351 is inclined.

[0035] Specifically, both the first scraper 351 and the second scraper 37 are in contact with the inner wall of the storage tank 3, allowing for full contact with the tank wall. When the scrapers rotate, they can directly scrape off the detergent adhering to the tank wall, reducing residue. At the same time, the inclined first scraper 351 exerts an oblique force on the detergent, causing the detergent to flow along the inclined direction of the scraper and guiding the detergent to quickly gather at the bottom of the storage tank 3 for easy centralized discharge. The first scraper 351 and the second scraper 37 work simultaneously, scraping the inner wall of the storage tank 3 from different angles and positions, which can more thoroughly clean the tank wall, avoid scraping dead corners, and further improve the discharge efficiency of residual detergent.

[0036] Working principle: Detergent is added to the storage tank 3. The electric telescopic rod 24 is activated and extended, which drives the pull rod 261 through the connecting plate 25. The pull rod 261 pulls the sealing plug 26 outward in the piston tank 2, creating a negative pressure inside the piston tank 2. At this time, the sealing ball 232 in the one-way tube 23 on the inlet pipe 21 overcomes the elastic force of the spring 235 under the action of negative pressure, driving the guide rod 234 to move towards the limit frame 233. The inlet 231 opens, and the detergent flows from the storage tank 3 into the piston tank 2 through the inlet pipe 21. Meanwhile, the sealing ball 232 in the one-way tube 23 on the outlet pipe 22 tightly blocks the inlet 231 under the action of the spring 235 and external pressure.

[0037] Then, the electric telescopic rod 24 retracts, pushing the pull rod 261 and the sealing plug 26 inward within the piston tank 2, increasing the pressure inside the piston tank 2. Under the pressure and the elastic force of the spring 235, the sealing ball 232 inside the one-way tube 23 on the inlet pipe 21 blocks the inlet port 231, preventing detergent from flowing back into the storage tank 3. Under the pressure, the sealing ball 232 inside the one-way tube 23 on the outlet pipe 22 overcomes the elastic force of the spring 235, opening the inlet port 231. The detergent in the piston tank 2 is then poured into the packaging container through the outlet pipe 22 and the filling nozzle. By precisely controlling the extension and retraction stroke of the electric telescopic rod 24, the movement distance of the sealing plug 26 within the piston tank 2 is determined, thereby controlling the volume of liquid drawn and filled each time, achieving quantitative filling.
