Description

Technical Field

[0001] This utility model relates to the technical field of filling, specifically to an anti-drip device for filling essence liquid. Background Technology

[0002] Serum filling is a core step in cosmetic production, crucial to product quality and brand image. This process is typically carried out in a highly clean, dust-free workshop, using automated or semi-automated precision filling equipment to inject high-concentration serum into strictly sterilized containers with milliliter-level precision.

[0003] According to Chinese Patent No. CN221093703U, an anti-drip filling head includes a filling tube with a liquid outlet end sealed and multiple liquid outlet holes on its side wall; it also includes a sealing assembly for sealing the liquid outlet holes of the filling tube; the sealing assembly includes a fixing sleeve, a spring, and a sealing shell connected in sequence on the filling tube, and the bottom of the sealing shell has a sealing ring protruding from its bottom surface for sealing the liquid outlet holes.

[0004] In the above solution, the protruding part at the bottom of the sealed shell is used to block the liquid outlet, which still has the following disadvantages: when blocking the liquid outlet, it is necessary to probe into the inside of the liquid outlet, and it will take a certain amount of time to block and open the liquid outlet. The liquid inside the liquid outlet may leak during the opening and closing gap. Utility Model Content

[0005] The purpose of this invention is to provide an anti-drip device for filling essence, in order to solve the problem that when the liquid outlet is blocked or opened, a certain amount of time is spent, and the liquid inside the outlet may drip during the opening and closing gap.

[0006] To achieve the above-mentioned utility model objectives, the present utility model adopts the following technical solution: a serum filling anti-drip device, including a sliding folding plate, the sliding folding plate being slidably disposed on one side of a filling nozzle, two positioning plates being fixed on the surface of the filling nozzle, a sliding hole being provided at the bottom of one side of the positioning plate, a sliding rod being slidably inserted inside the sliding hole, one end of the sliding rod being fixed to one side of the sliding folding plate, a return spring being wound around the surface of the sliding rod, and a nut being threadedly connected to one end of the sliding rod.

[0007] Preferably, the top surface of the horizontal plane of the sliding folding plate is provided with an installation groove, and a sealing gasket is fixed inside the installation groove.

[0008] Preferably, a support folding plate is provided on one side of the filling nozzle, an electric push rod is fixed on the top surface of the support folding plate, the telescopic rod of the electric push rod is slidably inserted into the top surface of the support folding plate, and a lifting plate is fixed at the bottom end of the telescopic rod of the electric push rod.

[0009] Preferably, a fixed arc plate is detachably provided on one side of the lifting plate, two limiting rings are fixedly sleeved on the filling nozzle, two threaded grooves are opened on one side of the lifting plate, two fixing bolts are provided on the fixed arc plate, and one end of the fixing bolt passes through the fixed arc plate and is threadedly connected to the threaded groove.

[0010] Preferably, a limiting plate is fixed on one side of the lifting plate, and a limiting opening is provided on one side of the supporting folding plate, with the limiting plate and the limiting opening slidingly engaged.

[0011] Preferably, a stabilizing hole is provided at the upper end of one side of the positioning plate, and two stabilizing rods are fixed on one side of the sliding folding plate, with the stabilizing hole and the stabilizing rods slidably inserted.

[0012] Compared with existing technologies, the essence filling anti-drip device that adopts the above technical solution has the following beneficial effects: 1. By combining the lateral force generated by moving the container with the elastic restoring force of the return spring, the sliding folding plate opens and closes synchronously as the container moves closer to or further away from the filling nozzle, thus effectively preventing the leakage of essence during the filling process. 2. The telescopic rod of the electric push rod moves downward, pushing the lifting plate to move down synchronously, which in turn drives the filling nozzle to descend, allowing it to smoothly enter or exit the bottle mouth. The filling nozzle is installed on one side of the lifting plate through a fixed arc plate and is fastened to the outer wall of the nozzle by a limit ring, thereby enhancing its installation stability on the lifting plate. Third, during the downward movement of the lifting plate, the limiting plate moves up and down synchronously along the limiting port, which can further improve the stability of the lifting plate during movement. At the same time, when the sliding plate slides laterally, the stabilizing rod moves laterally along the stabilizing hole, which also effectively enhances the structural stability during the sliding process.

[0018] The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0019] like Figure 1 and Figure 4 As shown, an anti-drip device for filling essence includes a sliding folding plate 2, which is slidably disposed on one side of a filling nozzle 1. Two positioning plates 3 are fixed on the surface of the filling nozzle 1. A sliding hole 4 is provided at the bottom of one side of the positioning plate 3. A sliding rod 5 is slidably inserted into the sliding hole 4. One end of the sliding rod 5 is fixed to one side of the sliding folding plate 2. A return spring 6 is wound around the surface of the sliding rod 5. A nut 7 is threaded to one end of the sliding rod 5. An installation groove 8 is provided on the top surface of the horizontal plane of the sliding folding plate 2. A sealing gasket 9 is fixed inside the installation groove 8.

[0020] During use, when the container moves directly below the filling nozzle 1, its lateral displacement will exert a lateral thrust on the sliding baffle 2, causing the sliding baffle 2 to push open from the nozzle 1. During the movement, the sliding baffle 2 drives the sliding rod 5 to slide synchronously along the sliding hole 4, thereby compressing the return spring 6 and accumulating its return elastic potential energy. After the container moves out from under the filling nozzle 1, the return spring 6 releases its rebound force, pushing the sliding baffle 2 to quickly return to its original position and re-seal the nozzle 1. The sliding baffle 2 is equipped with a rubber sealing gasket 9, which can effectively prevent liquid leakage. If the elasticity of the return spring 6 decreases due to long-term use, the operator can remove the nut 7 and replace the failed spring to ensure that the sliding baffle 2 continues to work reliably. The lateral force generated by moving the container and the elastic restoring force of the return spring 6 work together to make the sliding baffle 2 open and close synchronously as the container moves closer to or further away from the filling nozzle 1, thereby effectively preventing the leakage of essence during the filling process.

[0021] like Figure 2 and Figure 3As shown, a support plate 10 is provided on one side of the filling nozzle 1. An electric push rod 11 is fixed on the top surface of the support plate 10. The telescopic rod of the electric push rod 11 is slidably inserted into the top surface of the support plate 10. A lifting plate 12 is fixed at the bottom end of the telescopic rod of the electric push rod 11. A fixing arc plate 13 is detachably provided on one side of the lifting plate 12. Two limiting rings 14 are fixedly sleeved on the filling nozzle 1. Two threaded grooves 15 are opened on one side of the lifting plate 12. Two fixing bolts 16 are provided on the fixing arc plate 13. One end of the fixing bolt 16 passes through the fixing arc plate 13 and is threadedly connected to the threaded groove 15.

[0022] During use, the telescopic rod of the electric push rod 11 moves downward, pushing the lifting plate 12 to move down synchronously, which in turn drives the filling nozzle 1 to descend, allowing it to smoothly enter or exit the bottle mouth. The filling nozzle 1 is installed on one side of the lifting plate 12 through the fixed arc plate 13 and is fastened to the outer wall of the nozzle by the limiting ring 14, thereby enhancing its installation stability on the lifting plate 12.

[0023] like Figure 2 and Figure 4 As shown, a limit plate 17 is fixed on one side of the lifting plate 12, and a limit opening 18 is opened on one side of the supporting folding plate 10. The limit plate 17 and the limit opening 18 are slidably matched. A stabilizing hole 19 is opened at the upper end of one side of the positioning plate 3. Two stabilizing rods 20 are fixed on one side of the sliding folding plate 2. The stabilizing hole 19 and the stabilizing rods 20 are slidably inserted.

[0024] During use, as the lifting plate 12 moves downward, it drives the limiting plate 17 to slide up and down synchronously along the limiting port 18, which can further improve the stability of the lifting plate 12 during movement. At the same time, when the sliding folding plate 2 slides laterally, the stabilizing rod 20 moves laterally along the stabilizing hole 19, which also effectively enhances the structural stability during its sliding process.

[0025] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
