Description

Technical Field

[0001] This utility model relates to the technical field of nail polish dispensing equipment, specifically a color-developing nail polish filling equipment. Background Technology

[0002] Tinted nail polishes face significant technical challenges in storage and filling due to their content of volatile organic solvents (such as ethyl acetate and toluene) and easily oxidized and polymerized resin components.

[0003] Issues with easy spoilage during storage:

[0004] While traditional glass bottles or rigid plastic containers can hold nail polish, a physical gap exists between the cap and the bottle opening, preventing a complete seal. During long-term storage, continuous solvent evaporation leads to increased viscosity, while air infiltration triggers oxidation and polymerization reactions, causing clumping, layering, or discoloration. The industry commonly uses antioxidants to delay spoilage, but this doesn't eliminate the sealing defects, and chemical additives may affect safety and color rendering.

[0005] Secondary contamination and losses during the filling process:

[0006] Current filling methods mostly use gravity flow or pump-pressed open filling, which leaves the filling nozzle and bottle mouth exposed, causing solvent evaporation to pollute the environment and waste raw materials; manual operation can easily introduce dust, microorganisms and other pollutants, posing significant hygiene risks; high-viscosity nail polish requires pressurized filling, but rigid containers are prone to breakage under pressure, while flexible packaging lacks suitable closed filling equipment.

[0007] Therefore, there is an urgent need for a technical solution that combines high-sealing storage with non-exposed filling capabilities to improve the shelf life of colored nail polish after filling and reduce filling losses. Utility Model Content

[0008] (a) Technical problems to be solved

[0009] To address the shortcomings of existing technologies, this utility model provides a color-developing nail polish filling device, which solves the problems mentioned in the background art.

[0010] (II) Technical Solution

[0011] To achieve the above objectives, this utility model provides the following technical solution: a color-developing nail polish filling device, characterized in that it includes a filling machine outer shell and a storage inner liner. The filling machine outer shell has a pressurizing chamber, and the storage inner liner has a storage chamber. The storage inner liner is embedded in the pressurizing chamber. A pressurizing pipe is fixedly connected to one end face of the pressurizing chamber, and a pressurizing machine is fixedly connected to the pressurizing pipe. A filling outer tube is fixedly connected to one end face of the storage chamber. The filling outer tube penetrates the filling machine outer shell, and a filling inner tube is slidably disposed within the filling outer tube. A filling channel is formed within the filling inner tube. A first discharge port and a second discharge port are respectively formed at one end of the outer circumference of the filling channel. A clamping groove is formed on the side of the filling outer tube near the second discharge port, and a clamping component is disposed within the clamping groove.

[0012] Preferably, the clamping assembly includes a clamping base, a threaded rod, and a sealing clamping block. The clamping base has a threaded hole and a first sliding groove, which are connected through the clamping base. The threaded rod is threaded to the threaded hole, and the sealing clamping block is slidably connected to the first sliding groove. One end of the threaded rod is fixedly connected to a rotating base, and the other end of the threaded rod is rotatably connected to the sealing clamping block.

[0013] Preferably, a second sliding groove is formed on the inner circular surface of the filling outer tube, a limiting slider is fixedly connected to the outer circular surface of the filling inner tube, the limiting slider is slidably connected to the second sliding groove, and a limiting ring is fixedly connected to the outer circular surface of the filling inner tube, the limiting ring being used to limit the extreme position of the sliding of the filling inner tube relative to the filling outer tube.

[0014] Preferably, the width of the sealing clamping block is equal to the width of the clamping slot, the sealing clamping block is adapted to the threaded hole, and the end of the sealing clamping block away from the threaded rod is provided with anti-slip texture.

[0015] Preferably, the distance from the side of the second discharge port away from the filling machine housing to the side of the clamping slot away from the filling machine housing is equal to the distance from the limiting ring to the side of the filling outer tube away from the filling machine housing, and the thickness of the second discharge port is equal to the thickness of the clamping slot.

[0016] Preferably, the distance from the side of the first discharge port away from the storage cavity to the side of the storage cavity near the filling outer tube is equal to the distance from the limiting ring to the side of the filling outer tube away from the filling machine housing.

[0017] (III) Beneficial Effects

[0019] 1. This solution uses a storage liner made of corrosion-resistant flexible material and sets up a first discharge port and a second discharge port to completely isolate the nail polish inside the storage chamber from the outside air under storage conditions. This prevents the nail polish from evaporating, becoming contaminated, or undergoing chemical reactions such as oxidation or polymerization, thus maintaining product stability and extending shelf life.

[0020] 2. This solution uses a booster to pressurize and compress the storage liner in the booster chamber, and a clamping component to fix and seal the empty bottle to be filled. This allows the nail polish to flow into the bottle without exposure through the filling channel during the filling process, thereby preventing evaporation, leakage or secondary pollution during filling, achieving the goal of efficient and automated filling and improving hygiene and safety.

[0026] This utility model embodiment provides a color-developing nail polish filling device, such as... Figure 1-4 As shown, the filling machine includes a shell 11, a pressurizing chamber 12, a storage liner 13, a storage chamber 14, a pressurizing pipe 15, a pressurizer 16, a filling outer pipe 17, a filling inner pipe 18, a filling channel 19, a first discharge port 20, a second discharge port 21, a clamping slot 22, a clamping base 23, a threaded hole 24, a threaded rod 25, a rotating base 26, a first sliding groove 27, a sealing clamping block 28, a second sliding groove 30, a limiting slider 31, and a limiting ring 32.

[0027] like Figure 1-4As shown, a pressurizing chamber 12 is provided inside the outer shell 11 of the filling machine, and a storage chamber 14 is provided inside the storage liner 13. The storage liner 13 is embedded in the pressurizing chamber 12. A pressurizing pipe 15 is fixedly connected to one end face of the pressurizing chamber 12. A pressurizing machine 16 is fixedly connected to the pressurizing pipe 15. A filling outer tube 17 is fixedly connected to one end face of the storage chamber 14. The filling outer tube 17 passes through the outer shell 11 of the filling machine. A filling inner tube 18 is slidably arranged inside the filling outer tube 17. A filling channel 19 is provided inside the filling inner tube 18. A first discharge port 20 and a second discharge port 21 are respectively provided at one end of the outer circular surface of the filling channel 19. A clamping slot 22 is provided on the side of the filling outer tube 17 near the second discharge port 21. A clamping component is provided in the clamping slot 22.

[0028] It is worth noting that the storage liner 13 is made of a corrosion-resistant flexible material, specifically an aluminum-plastic composite film or a PE / PVC film with an internal anti-corrosion coating.

[0029] The first discharge port 20 and the second discharge port 21 ensure that the nail polish in the storage chamber 14 is isolated from the outside air under storage conditions, thereby preventing the nail polish from evaporating, becoming contaminated, or undergoing chemical reactions such as oxidation or polymerization that cause the nail polish to deteriorate.

[0030] The clamping assembly includes a clamping base 23, a threaded rod 25, and a sealing clamping block 28. The clamping base 23 has a threaded hole 24 and a first sliding groove 27, which are connected through the clamping base 23. The threaded rod 25 is threaded to the threaded hole 24, and the sealing clamping block 28 is slidably connected to the first sliding groove 27. One end of the threaded rod 25 is fixedly connected to a rotating base 26, and the other end of the threaded rod 25 is rotatably connected to the sealing clamping block 28.

[0031] A second sliding groove 30 is provided on the inner circular surface of the filling outer tube 17. A limiting slider 31 is fixedly connected to the outer circular surface of the filling inner tube 18. The limiting slider 31 is slidably connected to the second sliding groove 30. A limiting ring 32 is fixedly connected to the outer circular surface of the filling inner tube 18. The limiting ring 32 is used to limit the extreme position of the sliding of the filling inner tube 18 relative to the filling outer tube 17.

[0032] The width of the sealing clamping block 28 is equal to the width of the clamping slot 22. The sealing clamping block 28 is adapted to the threaded hole 24. The end of the sealing clamping block 28 away from the threaded rod 25 is provided with anti-slip texture.

[0033] The sealing clamping block 28 is designed to prevent the colored nail polish flowing out of the second outlet 21 from leaking.

[0034] The distance from the side of the second discharge port 21 away from the filling machine housing 11 to the side of the clamping slot 22 away from the filling machine housing 11 is equal to the distance from the limiting ring 32 to the side of the filling outer tube 17 away from the filling machine housing 11. The thickness of the second discharge port 21 is equal to that of the clamping slot 22. The distance from the side of the first discharge port 20 away from the storage cavity 14 to the side of the storage cavity 14 near the filling outer tube 17 is equal to the distance from the limiting ring 32 to the side of the filling outer tube 17 away from the filling machine housing 11.

[0035] When this solution is used for filling nail polish, firstly, the empty bottle to be filled is clamped in the clamping slot 22, and the rotating base 26 is rotated. The rotating base 26 drives the threaded rod 25 to rotate around the axis of the threaded rod 25. The threaded rod 25 is threadedly connected to the threaded hole 24, thereby moving towards the direction of the empty bottle to be filled. The threaded rod 25 pushes the sealing clamping block 28 to slide along the first sliding groove 27, and the sealing clamping block 28 clamps the empty bottle to be filled.

[0036] Then, push the inner filling tube 18 into the storage cavity 14, and slide the limiting slider 31 along the second sliding groove 30 until the limiting ring 32 contacts the side of the outer filling tube 17 away from the storage cavity 14. At this time, the first discharge port 20 enters the storage cavity 14, and the second discharge port 21 is aligned with the clamping slot 22. The empty bottle to be filled is aligned with the second discharge port 21.

[0037] Finally, the booster 16 is started. The booster 16 fills the booster chamber 12 with air through the booster pipe 15, thereby pressurizing the booster chamber 12. The increased air pressure in the booster chamber 12 compresses the storage liner 13. The storage liner 13 squeezes the nail polish in the storage chamber 14 into the filling channel 19 through the first discharge port 20, and into the empty bottle to be filled through the second discharge port 21.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
