Description

Technical Field

[0001] This utility model relates to the field of paint filling technology, and in particular to a paint filling anti-drip device. Background Technology

[0002] Filling is an essential packaging step in paint production, and this operation is generally carried out using paint filling machines.

[0003] However, existing paint filling machines are not equipped with corresponding pressure reducing and anti-drip devices. During the paint filling process, they are easily affected by pneumatic high pressure, which can cause splashing. After the filling operation, the filling nozzle may drip paint due to its own structure, resulting in low overall filling efficiency and affecting the performance of subsequent use. In addition, the existing filling protection components are not easy to install and use on paint filling machines, and disassembly and assembly are relatively troublesome. Therefore, the overall performance is generally poor and the scope of application is limited.

[0004] Based on this, the present invention proposes a paint filling anti-drip device to solve the above problems. Utility Model Content

The threaded sleeve 3 and the inner guide groove 2 are interconnected. A mating sleeve 13 is fixedly connected to the upper end of the anti-drip filling head 10. The pressure-reducing filling guide frame 1 is assembled with the anti-drip sleeve 4 and the mating sleeve 13 through mutual alignment. The outer diameter of the anti-drip sleeve 4 corresponds to and matches the inner diameter of the mating sleeve 13. A pressure-reducing mesh plate 12 is movably installed at the bottom of the anti-drip sleeve 4, and its inner diameter corresponds to and matches the outer diameter of the pressure-reducing mesh plate 12.

After a single filling, it can use its own structure to generate tension to support and protect the remaining coating inside, preventing it from dripping. This effectively ensures the overall safety of use and the anti-drip effect of the coating filling operation.

[0038] Working principle:

[0039] By assembling this device onto the filling nozzle of a paint filling machine, drip-proof filling of designated containers can be achieved. The mating flange 5 is stably threaded onto the outside of the mating threaded sleeve 3 via a threaded adapter connection structure between the internal threaded sleeve 8 and the mating threaded sleeve 3. Depending on the assembly method of the paint filling machine nozzle, if the nozzle uses flange mating, aligning the mating flange 5 with the nozzle will achieve the alignment of the pressure-reducing filling guide frame 1 on the paint filling machine. If the paint filling machine uses a threaded connection assembly structure, the pressure-reducing filling guide frame 1 can be aligned with the nozzle. The pressure-reducing filling guide frame 1 is aligned and assembled with the filling nozzle through the internal threaded groove 7 of the threaded sleeve 3, ensuring stable installation of the pressure-reducing filling guide frame 1 on the paint filling machine. The paint filling machine, pneumatically controlled, guides the material into the inner guide trough 2. Under pressure, the paint is diverted from the pressure-reducing diversion trough 6 inside the inner guide trough 2, increasing filling smoothness, and then converges into the anti-drip associated sleeve 4. After passing through the pressure-reducing mesh plate 12, the pressure is reduced again, and the paint is filled into the designated container from the anti-drip filling head 10. Under pressure, the anti-drip spring... The elastic film 19 expands outward under its own elastic structure, allowing for smooth paint filling. After filling, the anti-drip elastic film 19 rebounds into the anti-drip filling head 10, generating tension to support any remaining paint, thus effectively preventing paint dripping during and after the filling process. The pressure-reducing mesh plate 12 is aligned and inserted into the positioning slot 16 via the alignment and fastening assembly block 17, and then rotated into the rotating fastening slot 18 for fastening. This enables the pressure-reducing mesh plate 12 to be rotated and fastened inside the anti-drip associated sleeve 4, facilitating the anti-drip function of the pressure-reducing mesh plate 12. The quick disassembly and assembly of the leak-proof sleeve 4 facilitates the regular maintenance or replacement of the pressure-reducing mesh plate 12. The anti-drip filling head 10, through the installation structure between the mating sleeve 13 and the anti-drip sleeve 4, is assembled and secured by inserting the alignment assembly block 11 into the bottom of the mating slot 14 and rotating it into the rotating locking groove 15. This quick disassembly device structure makes the replacement of the anti-drip filling head 10 at the bottom of the pressure-reducing filling guide frame 1 faster and more convenient, which helps to expand the overall applicability and thus effectively improves the overall comprehensive performance.
