Description

Technical Field

[0001] This utility model relates to the field of solvent dripping technology, and in particular to a dripping device. Background Technology

[0002] The water-based paint dripping device originated from the strict control of VOC emissions, which has driven the technological innovation of oil-to-water conversion. The device is compatible with water-based paints of various viscosities and can be applied in automotive, furniture, and construction machinery scenarios, promoting the upgrading of the coating industry towards high efficiency and environmental protection.

[0003] When applying water-based paints, issues such as excessively thick wet film, uneven gloss, inconsistent coating thickness, or excessive chalking leading to an insufficiently thin film can arise. Over-dilution or substrate water absorption can also cause chalking, resulting in inadequate film thickness. Therefore, a dripping device is required. However, traditional devices often employ straight cylinders or simple baffle structures, which are prone to creating turbulent dead zones or uneven mixing. The low shear force prevents the uniform dispersion of pigments or resins in the water-based paint, easily leading to clumping due to excessively high local concentrations or sedimentation in low-viscosity areas. This further results in coating sagging, uneven gloss, and poor adhesion, reducing the practicality of the dripping device and increasing economic costs. Utility Model Content

Detailed Implementation

[0021] 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.

[0022] 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.

[0023] 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.

[0024] Example 1:

[0025] Reference Figures 1-4 This is the first embodiment of the present invention. This embodiment provides a dripping device, including a tank 1, and a flow stabilizing component 2 is provided on the inner wall of the tank 1.

[0026] Tank 1 serves as the main container of the device, holding water-based paint raw materials and providing space for reaction or mixing.

[0027] The flow stabilizing component 2 includes a threaded connecting ring 201 fixedly connected to the inner wall of the tank 1. A flow guide cylinder 202 is threadedly connected to the inner wall of the threaded connecting ring 201. A spiral groove 203 is formed on the inner wall of the flow guide cylinder 202. A spiral guide plate 204 is rotatably connected to the inner wall of the flow guide cylinder 202. A connecting shaft 205 is fixedly connected to the inner wall of the spiral guide plate 204. A connecting rod 206 is fixedly connected to the outer side of the connecting shaft 205. A stirring blade 207 is fixedly connected to the outer side of the connecting rod 206.

[0028] The threaded connecting ring 201 is used to connect the guide tube 202 to the inner wall of the tank 1, enabling detachable installation. The guide tube 202 guides the paint into the tank and forms a spiral flow path, enhancing the mixing effect. The spiral groove 203 and the spiral guide plate 204 work together to form a spiral flow channel, strengthening fluid mixing. The guide tube 202 is connected to the output end of the drive motor 5 via the connecting shaft 205. When the spiral guide plate 204 rotates on the inner wall of the guide tube 202, its blades move relative to the spiral groove 203 on the inner wall of the guide tube 202, causing... Within the spiral flow channel, the paint experiences forced vortices due to the spiral structure, subjecting it to shearing and mixing. Furthermore, the changes in the spiral channel's cross-section and the spiral direction result in tangential and axial forces along the spiral direction, enhancing turbulence and promoting mixing. When the paint flows through the spiral channel formed by the spiral groove 203 and the spiral guide plate 204, the changes in the channel's cross-section and the spiral direction cause tangential and axial forces along the spiral direction, creating forced vortices and further enhancing turbulence, thus mixing the pigments within the paint. The resin and other components are thoroughly mixed, while reducing dead zones and preventing paint accumulation in corners. The drive motor 5 directly drives the connecting shaft 205 via coupling 6. The connecting shaft 205, through connecting rod 206, simultaneously rotates the spiral guide plate 204 and the stirring blade 207, forming a synergistic structure of a single power source and dual actuators. The stirring blade 207 generates strong shearing force, breaking up agglomerates in the paint and promoting dispersion. Simultaneously, the synergistic effect of the stirring blade 207 and the spiral guide plate 204 improves mixing efficiency. It should be noted that, if necessary, the spiral groove 203... The spiral guide plate 204 can be rotatably connected to the spiral guide plate 204 via a miniature bearing 608ZZ deep groove ball bearing to form low-friction rotation. Fluororubber O-rings are installed to prevent paint from seeping into the bearing area, ensuring long-term stable operation. The gap between the spiral guide plate 204 and the spiral groove 203 needs to be controlled between 0.1 and 0.3 mm to ensure that the paint always flows in the direction of the spiral guide plate 204. In addition, the spiral guide plate 204 needs to be made of stainless steel 304 with anodized surface and a thickness ≥2 mm to withstand the shear force generated by the stirring blade 207.

[0029] Example 2:

[0030] This is the second embodiment of the present invention, which is based on the previous embodiment.

[0031] Specifically, the top of the tank body 1 is fixedly connected to a first connecting flange 3 by bolts, and a sealing plate 4 is fixedly connected to the top of the first connecting flange 3.

[0032] The first connecting flange 3 is used to seal the top of the tank 1, and can also be used to fix the whole device in other positions by bolts. In addition, the first connecting flange 3 can also be equipped with a paint inlet to connect with external paint dispensing equipment. The sealing plate 4 is used to seal the connection between the coupling 6 and the first connecting flange 3 to prevent leakage.

[0033] Specifically, a drive motor 5 is fixedly connected to the top of the sealing plate 4 via a bracket, and a coupling 6 is fixedly connected to the output end of the drive motor 5 through the first connecting flange 3. The outer side of the coupling 6 is fixedly connected to the outer side of the connecting rod 206.

[0034] The drive motor 5 serves as the power source for the flow stabilizing component 2, directly driving the stirring blade 207 and the spiral guide plate 204. The coupling 6 serves as the connecting component connecting the drive motor 5 and the connecting rod 206, and is mainly used to transmit the rotational power of the drive motor 5.

[0035] Specifically, a support column 7 is fixedly connected to the outside of the tank body 1, and the outside of the support column 7 is covered with a frosted coating 8.

[0036] The support column 7 provides structural support and can also be used as a temporary handle to improve the portability of the device. The frosted coating 8 increases friction with the hands or tools of the operator, improving stability during transport. The material of the frosted coating 8 can be PET polyester or polyurethane. The PET polyester coating provides high abrasion resistance, while the polyurethane coating provides a flexible and non-slip surface to adapt to different operating environments.

[0037] Example 3:

[0038] This is the third embodiment of the present invention, which is based on the first two embodiments.

[0039] Specifically, a second connecting flange 9 is fixedly connected to the bottom of the tank body 1. An L-shaped connecting post 10 and a sealing ring 16 are fixedly connected to the bottom of the second connecting flange 9. A patch 11 is fixedly connected to the outside of the L-shaped connecting post 10. The outside of the patch 11 is rotatably connected to the outside of the guide tube 202.

[0040] The second connecting flange 9 seals the bottom of the tank 1 to prevent leakage and can be bolted to connect the device to other equipment. The L-shaped connecting column 10 supports the patch 11 to prevent it from shifting. The patch 11 fits against the outside of the guide tube 202 to assist in supporting the guide tube 202. The sealing ring 16 seals the connection between the guide tube 202 and the second connecting flange 9 to prevent leakage when the device is started. The sealing ring 16 is made of food-grade silicone with a temperature range of -40℃ to 200℃ to ensure no risk of leakage.

[0041] Specifically, a drip nozzle 12 is fixedly connected to the bottom of the guide tube 202, and a control valve 13 is fixedly connected to the bottom of the drip nozzle 12.

[0042] The nozzle 12 and the control valve 13 work together to control the paint dripping speed and flow rate, enabling a thin-coat, multi-layer process. It should be noted that the nozzle 12 is designed with a tapered or expanding flow channel to reduce fluid resistance and prevent clogging. The expanding structure can reduce the fluid flow rate and reduce the generation of bubbles, while the tapered structure can improve the controllability of dripping. The control valve 13 controls the flow rate by adjusting the opening degree. The model of the control valve 13 is Q41F-16P or J941H-16. This technology is common knowledge to those skilled in the art and will not be elaborated further here.

[0043] Specifically, an inverted conical guide block 14 is fixedly connected to the inner wall of the tank 1, and the outer side of the inverted conical guide block 14 is covered with an anti-stick coating 15.

[0044] The inverted conical guide block 14 utilizes gravity to allow the paint to slide down the inclined surface to the inlet of the guide tube 202, avoiding the problem of material accumulation in the corner of the flat-bottomed tank. The anti-stick coating 15 is made of polytetrafluoroethylene to reduce surface energy, reduce paint adhesion, reduce waste liquid generation, and the thickness is controlled at 50-100μm to ensure corrosion resistance and easy cleaning.

[0045] When using water-based paint, first open the first connecting flange 3 to ensure there are no foreign objects inside the tank 1. Then, introduce the paint into the tank 1 through the inlet added to the first connecting flange 3. Next, turn on the drive motor 5 to rotate the connecting shaft 205, which in turn drives the connecting rod 206 and the stirring blade 207 to rotate synchronously, thus dispersing the paint inside the tank 1 and improving its uniformity. At the same time, the connecting rod 206 also drives the connecting shaft 205 and the spiral guide plate 204 to rotate synchronously. At this time, the spiral guide plate 204 and the spiral groove 203 cooperate. Shear force is generated to ensure that the paint always flows in the path of the spiral guide plate 204. Then, the nozzle 12 is opened by the control valve 13 to let the paint flow out. The opening and closing of the control valve 13 is operated according to the required amount of paint to avoid the situation of too much paint or too little paint. As the paint flows out, the combined action of the stirring blade 207 and the spiral guide plate 204 forms a swirling shearing and spiral propulsion composite flow mode, which improves the practicality of the device. After use, the bolts of the first connecting flange 3 and the second connecting flange 9 are contacted, and the entire flow stabilizing component 2 is pulled out for cleaning.

[0046] 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.
