Description

Technical Field

[0001] This utility model relates to the field of water-based paint packaging technology, and in particular to a filling head. Background Technology

[0002] Water-based paint is an environmentally friendly coating that uses water as the main solvent or dispersion medium. It forms an emulsion by being evenly dispersed in water. During application, the water evaporates, leaving a cured paint film. Water-based paint uses water instead of organic solvents, reducing fire hazards. Application tools can be directly cleaned with water, eliminating the need to purchase additional thinner, thus saving resources and reducing operating costs. In terms of performance, water-based paint has excellent application adaptability. Its paint film has a microporous structure, which is highly breathable and reduces blistering or peeling on walls. It has excellent adhesion and can be applied directly in humid environments or enclosed spaces without the need for special ventilation equipment. In addition, water-based paint supports brushing, rolling, or spraying, has a moderate drying speed, and is flexible in color matching, easily mixing with water-based pigments to meet personalized needs. When repairing, there is no obvious color difference in localized painting. Post-repair maintenance is simple, and its application fields are wide, covering home decoration and industrial scenarios. With the increasing health awareness of consumers, water-based paint, with its dual advantages of environmental protection and performance, is gradually becoming the mainstream choice in the coating market.

[0003] Water-based paints, due to their environmentally friendly nature of using water as a diluent, require safe and efficient filling processes through filling heads in industrial production. However, in current practical applications, water-based paint filling heads are prone to paint residue during use. If they are not easily disassembled, cleaning becomes extremely difficult. If the residual paint dries and clogs the channels, it will affect subsequent fillings and may even damage the internal structure of the equipment. In addition, water-based paints are highly susceptible to various impurities during production, storage, and transportation. If the filling head cannot filter these impurities, they will directly enter the filling container along with the paint, leading to a decrease in the purity of the water-based paint after filling. This will affect its physical and chemical properties, resulting in roughness, peeling, and orange peel defects on the surface of the coated product, seriously affecting product quality and appearance, and reducing the product's market competitiveness.

[0023] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0024] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0025] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0026] Example 1:

[0027] Reference Figures 1-5 This is the first embodiment of the present utility model. This embodiment provides a filling head, including an installation tube 1, one end of the installation tube 1 is connected to a discharge tube 2, an installation ring 3 is snapped onto the outside of the discharge tube 2, a filter assembly 4 is provided inside the installation tube 1, and an installation assembly 5 is provided at one end of the installation tube 1.

[0028] As the main structure of the water-based paint filling head, the installation pipe 1 serves to transport the water-based paint and support other components. It provides a channel for the water-based paint to flow from the inlet to the outlet, ensuring the stability and functionality of the entire filling head structure. The outlet pipe 2 serves as the final channel for the water-based paint to flow out of the filling head and into the packaging container. The installation ring 3 provides a fulcrum for the installation of the filter assembly 4. The filter assembly 4 filters the water-based paint as it flows through the installation pipe 1 into the container, intercepting solid impurities and ensuring that the filled water-based paint meets quality standards, thus improving product quality and stability. The installation assembly 5 facilitates the installation and disassembly of the installation pipe 1, i.e., the entire filling head, enabling maintenance, cleaning, and component replacement of the filling head, while ensuring the sealing of the connections to prevent leakage of water-based paint during the filling process.

[0029] The filter assembly 4 includes a filter screen 41 fixedly connected to the inner wall of the mounting ring 3. The inner wall of the mounting tube 1 is provided with a snap-fit ​​groove 42, and the inner wall of the snap-fit ​​groove 42 snaps into the outer side of the filter screen 41.

[0030] The filter screen 41 is designed to filter water-based paint, ensuring that the water-based paint being filled meets quality standards. The snap-fit ​​groove 42 is designed to fix the filter screen 41, ensuring that the filter screen 41 will not shift or loosen under the impact of the water-based paint, thus continuously and effectively performing its filtering function.

[0031] The mounting assembly 5 includes a mounting thread 51 fixedly connected to the outside of the discharge pipe 2. A connecting shell 52 is rotatably connected to the outside of the mounting pipe 1, and the inner wall of the connecting shell 52 is threadedly connected to the outside of the mounting thread 51.

[0032] The installation thread 51 and the connecting shell 52 are used to achieve a stable connection between the installation pipe 1 and the discharge pipe 2. The threaded connection facilitates installation and disassembly, makes it easy to maintain and clean the filling head, and ensures the sealing of the connection to prevent water-based paint from leaking during the filling process.

[0033] Example 2:

[0034] This is the second embodiment of the present invention, which is based on the previous embodiment.

[0035] Specifically, a limiting ring 6 is fixedly connected to the outer side of the installation pipe 1, and the outer side of the limiting ring 6 is rotatably connected to the inner wall of the connecting shell 52. A sealing ring 7 is provided on the inner wall of the discharge pipe 2.

[0036] The limiting ring 6 restricts the movement range of the connecting shell 52, preventing it from moving horizontally along the axial direction of the mounting pipe 1 during rotation. This would cause the connecting shell 52 to detach from the mounting pipe 1, losing its limiting effect and leading to unstable connection and water-based paint leakage. The sealing ring 7 prevents water-based paint from leaking from the connection between the discharge pipe 2 and the mounting pipe 1, ensuring the sealing of the filling process, improving filling efficiency, and avoiding waste of water-based paint and pollution to the surrounding environment.

[0037] Specifically, the inner wall of the installation pipe 1 is connected to the water inlet pipe 8, and the outer side of the water inlet pipe 8 is equipped with a valve 9.

[0038] The water inlet pipe 8 is designed to introduce cleaning water into the installation pipe 1. After the filling operation is completed, clean water can be introduced through the water inlet pipe 8 to clean the inside of the installation pipe 1 and the filter assembly 4, remove residual water-based paint, prevent the water-based paint from clogging the pipe after drying or affecting the quality of the next filling, and ensure the cleanliness and normal use of the filling head. The valve 9 is designed to control the opening and closing of the water inlet pipe 8, and also to prevent water-based paint from entering the water inlet pipe 8 during the filling process.

[0039] Specifically, a ball valve 10 is provided on the inner wall of the installation pipe 1, and a fixing ring 11 is fixedly connected to the inner wall of the installation pipe 1.

[0040] The ball valve 10 is used to control the flow of water-based paint in the installation pipe 1. By operating the opening and closing of the ball valve 10, it is possible to control whether the water-based paint can enter the discharge pipe 2 through the installation pipe 1 for filling, so as to realize flexible control of the filling process and meet different filling requirements. The fixing ring 11 is used to further improve the sealing performance of the ball valve 10 after it is closed, and prevent the water-based paint from leaking through the gap between the ball valve 10 and the installation pipe 1.

[0041] Specifically, a connecting rod 12 is fixedly connected to the top of the ball valve 10, and an actuating frame 13 is rotatably connected to the outside of the mounting tube 1, with the inner wall of the actuating frame 13 fixedly connected to the outside of the connecting rod 12.

[0042] The connecting rod 12 can transmit the rotational motion of the actuating frame 13 to the ball valve 10, and the opening and closing of the ball valve 10 can be controlled by rotating the actuating frame 13, realizing remote operation of the water-based paint flow, improving the convenience and safety of operation. The actuating frame 13 can be easily rotated by the operator.

[0043] Example 3:

[0044] This is the third embodiment of the present invention, which is based on the first two embodiments.

[0045] Specifically, the inner wall of the mounting tube 1 is fixedly connected with a snap ring 14, and the inner wall of the mounting ring 3 is provided with a sealing groove 15, and the inner wall of the sealing groove 15 is snapped with the outer side of the snap ring 14.

[0046] The engagement ring 14 and the sealing groove 15 work together to form a sealing structure after the mounting ring 3 and the mounting tube 1 are closed, effectively preventing water-based paint from leaking from the connection between the mounting ring 3 and the mounting tube 1, ensuring that the water-based paint can pass smoothly through the filling head for filling according to the predetermined path, thereby improving filling quality and efficiency.

[0047] Specifically, the inner wall of the mounting ring 3 is threadedly connected to a limiting bolt 16, and the outer side of the mounting tube 1 is fixedly connected to a limiting block 17, with the inner wall of the limiting block 17 threadedly connected to the outer side of the limiting bolt 16.

[0048] The limiting bolt 16 can be further fixed after the mounting ring 3 and the mounting tube 1 are closed. At the same time, it is convenient to release the limiting of the mounting ring 3 when needed, so as to facilitate the cleaning or replacement of the filter screen 41. The limiting block 17 can cooperate with the limiting bolt 16 to fix the mounting ring 3, enhance the connection stability between the mounting ring 3 and the mounting tube 1, and ensure that the entire filling head is structurally reliable during long-term use and can continuously and stably complete the filling task of water-based paint.

[0049] In use, first align one end of the connecting shell 52 with one end of the discharge pipe 2. Then rotate the connecting shell 52. The connecting shell 52 rotates along the mounting thread 51 on the outside of the discharge pipe 2, thereby driving the mounting pipe 1 to move horizontally until it stops against the discharge pipe 2. Then rotate the actuating frame 13. The actuating frame 13 drives the connecting rod 12 and the ball valve 10 to rotate, thereby releasing the limit on the water-based paint. At this time, the water-based paint is discharged into a suitable container through the guide of the mounting pipe 1 and the filter screen 41. Then close the ball valve 10. It should be noted that after the ball valve 10 is opened, the valve 9 needs to be in the closed state. Then, before the water-based paint dries, turn the valve 9 to open the water inlet pipe 8. Clean water enters the mounting pipe 1 through the guide of the water inlet pipe 8, thereby rinsing the part of the mounting pipe 1 and the filter screen 41 on the right side of the ball valve 10. At the same time, the clean water after cleaning is discharged from the discharge port of the mounting pipe 1.

[0050] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
