Technical Field

[0001] This utility model relates to the field of water-based coating filling equipment, and in particular to a water-based polyurethane coating filling device. Background Technology

[0002] In the field of coating production and processing, waterborne polyurethane coatings are widely used in various industries such as construction, furniture, and automobiles due to their advantages such as being environmentally friendly and pollution-free, having strong adhesion, and good flexibility. As the final and crucial step in the production of waterborne polyurethane coatings, the filling method and equipment performance directly determine the final product quality, production efficiency, and raw material loss rate.

[0003] Submersible filling has gradually become the mainstream choice for waterborne polyurethane coating filling because it can effectively solve problems such as splashing and foaming of viscous materials. However, the current submersible filling equipment still has many technical pain points and cannot meet the needs of refined production.

[0004] However, existing submersible filling devices have obvious shortcomings in practical applications: In terms of filling cleanliness, a large amount of residual paint easily adheres to the outer wall of the filling section during the process of submerging into the container and resetting. After the filling port leaves the liquid surface, there is a lack of timely cleaning and anti-drip structure, and the residual paint on the outer wall is very likely to drip, which not only wastes raw materials, but also contaminates the outer wall of the container and the production table, increasing subsequent cleaning costs. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a water-based polyurethane coating filling device, which aims to solve the problem in the prior art that "a large amount of residual coating is easily attached to the outer wall of the filling part of the submersible filling device, and there is a lack of timely cleaning and anti-drip structure after the filling port leaves the liquid surface, which makes the residual coating very easy to drip, resulting in waste of raw materials, pollution of the outer wall of the container and the production table, and increased subsequent cleaning costs".

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a water-based polyurethane coating filling device, including a filling part, a cleaning mechanism is provided on the outside of the filling part, and a mounting bracket for fixing to the filling equipment is fixedly connected to the rear side of the cleaning mechanism. The cleaning mechanism includes a sleeve fitted over the outside of the filling section. The upper part of the sleeve has multiple sets of mounting grooves. A rubber component is snapped between the sleeve and the outside of the mounting grooves by a mounting assembly. The inner ring surface of the rubber component is in contact with the outside of the filling section. A fixing lug is fixedly connected to the outside of the sleeve. A rotating part is rotatably connected to the lower part of the fixing lug. The upper part of the rotating part is elastically connected to the outside of the fixing lug by a tension spring. A sealing assembly is fixedly installed on the inner wall of the rotating part by bolts.

[0007] As a further description of the above technical solution: The mounting assembly includes multiple sets of support blocks, which are evenly arranged on the outer arc surface of the sleeve. A positioning ring is slidably connected to the inner wall of each support block, and a fastening bolt is threaded to the inner wall of each support block. The end of the fastening bolt is pressed against the outer arc surface of the positioning ring. An arc-shaped protrusion is provided on the inner ring surface of the positioning ring. Multiple sets of positioning blocks are fixedly connected to the outer side of the rubber component. A groove is opened on the outer side of each positioning block, and the arc-shaped protrusion of the positioning ring is inserted into the inner wall of the groove of the positioning block.

[0008] As a further description of the above technical solution: The enclosure assembly includes a base plate disposed at the lower part of the sleeve. A mounting plate is fixedly connected to the right side of the base plate, and a rubber slider is fixedly connected to the upper part of the mounting plate.

[0014] This utility model has the following beneficial effects: 1. In this utility model, the inner ring surface of the rubber part of the cleaning mechanism is tightly attached to the outer side of the filling part.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0019] Reference Figure 1 - Figure 3This utility model provides an embodiment of a water-based polyurethane coating filling device, including a filling section 1, which is a component of a submersible filling device capable of being inserted into the bottom of a container. This section is responsible for accurately delivering the water-based polyurethane coating to the target container, reducing foaming and material splashing. A cleaning mechanism 2 is provided on the outer side of the filling section 1, which can remove residual coating from the outer wall of the filling section 1 and seal it after the filling section 1 is reset, preventing coating dripping and ensuring filling cleanliness. A mounting bracket for fixing to the filling equipment is fixedly connected to the rear side of the cleaning mechanism 2. The frame 3 provides stable support; the cleaning mechanism 2 includes a sleeve 21, which provides an installation carrier for the cleaning and sealing components. The sleeve 21 is fitted onto the outside of the filling section 1. The upper part of the sleeve 21 has multiple sets of mounting grooves 22, which provide precise installation positions for the rubber parts 23, facilitating quick positioning of the rubber parts 23, while reserving a certain amount of room for movement to accommodate slight deformation of the rubber parts 23; the rubber parts 23 are snapped onto the outside of the sleeve 21 and the mounting grooves 22 by mounting components 24, and the inner ring surface is tightly fitted to the filling section 1. When moving up and down, residual paint on the surface is scraped off, allowing excess paint to flow down into the container. The inner ring surface of the rubber part 23 fits against the outer side of the filling part 1. A fixing ear 25 is fixedly connected to the outer side of the sleeve 21, serving as a mounting fulcrum for the rotating part 26 and providing stable rotational support for the rotating part 26, ensuring smooth opening and closing of the sealing assembly 27. The lower part of the fixing ear 25 is rotatably connected to the rotating part 26, connecting the fixing ear 25 and the sealing assembly 27. It can rotate around the fixing ear 25, driving the sealing assembly 27 to open and close the outlet of the filling part 1. In the combined action, the upper part of the rotating part 26 is elastically connected to the outer side of the fixed ear 25 through a tension spring 28. The elastic force pulls the rotating part 26, so that the sealing component 27 of the filling part 1 in the reset state fits tightly against the sleeve 21, enhancing the sealing effect and realizing automatic reset after filling. The inner wall of the rotating part 26 is fixedly installed with the sealing component 27 by bolts. When the filling part 1 is in the reset state, it seals the outlet of the filling part 1 to prevent excess paint from dripping. During filling, it can be opened as the filling part 1 descends without affecting the filling process.

[0020] Reference Figure 1 - Figure 3The mounting assembly 24 includes multiple sets of support blocks 241, evenly distributed on the outer arc surface of the sleeve 21, providing sliding support for the positioning ring 242. The support blocks 241 are evenly arranged on the outer arc surface of the sleeve 21. The positioning ring 242 is slidably connected to the inner wall of the support block 241. The arc-shaped protrusion on the inner ring surface of the positioning ring 242 engages with the groove of the positioning block 244, enabling quick snap-fit ​​fixing of the rubber part 23 and ensuring a secure installation of the rubber part 23. Fastening bolts 243 are threadedly connected to the inner wall of the support block 241. By rotating the fastening bolts 243, the positioning ring 242 is compressed and locked. The positioning is convenient for disassembly and adjustment. The end of the fastening bolt 243 is pressed against the outer arc surface of the positioning ring 242. The inner ring surface of the positioning ring 242 is provided with an arc-shaped protrusion, which is precisely matched with the groove of the positioning block 244, enhancing the connection stability between the positioning ring 242 and the rubber part 23. Multiple sets of positioning blocks 244 are fixedly connected to the outside of the rubber part 23. With the arc-shaped protrusion of the positioning ring 242, the positioning installation of the rubber part 23 is realized, preventing the rubber part 23 from shifting during operation. The outer side of the positioning block 244 is provided with a groove, and the arc-shaped protrusion of the positioning ring 242 is inserted into the inner wall of the groove of the positioning block 244. Reference Figure 1 - Figure 3 The sealing assembly 27 includes a base plate 271 for blocking the outlet of the filling section 1. The base plate 271 has an inclined outer edge for guiding the paint into the filling container. The base plate 271 is located at the lower part of the sleeve 21. A mounting plate 272 is fixedly connected to the right side of the base plate 271 for fixing a rubber slider 273. A rubber slider 273 is fixedly connected to the upper part of the mounting plate 272. The rubber slider 273 is semi-circular with rounded edges. As the filling section 1 continues to descend, the base plate 271 is in continuous contact with the outer side of the filling section 1 until the base plate 271 is fully opened. At this time, the rubber slider 273 slides on the outer side of the filling section 1 to avoid scratching the outer wall of the filling section 1. The left side of the base plate 271 is fixedly installed with the rotating part 26.

[0021] Reference Figure 2 - Figure 4A sealing gasket 4 is fixedly connected to the lower part of the sleeve 21, filling the gap between the sleeve 21 and the base plate 271, enhancing the sealing performance, and preventing paint evaporation and dust ingress. Two sets of sealing parts 5 are fixedly connected to the lower part of the sealing gasket 4. The lower opposite sides of the two sets of sealing parts 5 are set as inclined surfaces, which are adapted to the outer side of the base plate 271 to improve the sealing fit and form double sealing protection. The lower part of the sealing part 5 is attached to the outer side of the base plate 271. The rubber slider 273 is set as a semi-circle, and the arc edge of the rubber slider 273 is set as rounded corners to improve the compatibility with the filling part 1 and reduce friction damage during cleaning. The two sides of the upper part of the mounting groove 22 are set as opposite inclined surfaces to facilitate the quick insertion and positioning of the rubber part 23, reduce the installation difficulty, and improve the assembly efficiency. The fixing ear 25 is set as an L shape. The lower part of the base plate 271 is provided with reinforcing ribs to improve the load-bearing capacity and deformation resistance of the base plate 271 and extend the service life of the sealing component 27.

[0022] Working principle: When in use, the entire device is first fixed to the corresponding filling equipment by the mounting bracket 3. At this time, the tension spring 28 is in a naturally contracted state, pulling the rotating part 26 to tighten towards the sleeve 21, which drives the bottom plate 271 of the sealing component 27 to fit tightly against the sealing part 5 at the bottom of the sleeve 21, firmly sealing the outlet of the filling part 1.

[0023] After the filling equipment is started, the filling section 1 moves downward to begin the filling operation. As the filling section 1 moves downward, its bottom first presses against the bottom plate 271. The filling section 1 continues to apply downward pressure to overcome the elastic force of the tension spring 28, pushing the rotating part 26 to rotate outward around the connection of the fixed ear 25, thereby causing the bottom plate 271 to flip open and expose the discharge port of the filling section 1. At this time, the rubber slider 273 slides on the outside of the filling section 1. Since the rubber slider 273 is semi-circular and the arc edge is rounded, it can reduce friction damage with the filling section 1 and reduce the contact area with the coating.

[0024] After filling is completed, the filling part 1 is reset upward. During the reset process, the outer side of the filling part 1 rubs tightly against the rubber part 23. The rubber part 23 completely scrapes off the residual water-based polyurethane coating on the surface of the filling part 1, allowing the residual water-based polyurethane coating to flow into the filling container. At the same time, as the filling part 1 moves upward, the elastic force of the tension spring 28 is released, pulling the rotating part 26 to reset quickly. The bottom plate 271 re-fits the sealing part 5, and the device returns to the initial sealing state, reducing the dripping of coating. Then the filling container is removed.

[0025] When the rubber part 23 wears out due to long-term use and needs to be replaced, the fastening bolts 243 on the support block 241 can be loosened to release the compression and fixation on the positioning ring 242. The positioning ring 242 can be slid to make the arc-shaped protrusion on the inner ring surface disengage from the groove of the positioning block 244 on the outer side of the rubber part 23, so that the old rubber part 23 can be removed and the new rubber part 23 can be embedded into the mounting groove 22 of the sleeve 21. The above steps can be reversed, which is efficient and convenient.

[0026] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
