Technical Field
[0001] This utility model relates to the field of coating production technology, specifically a coating dilution device for coating production. Background Technology
[0002] Coatings, as materials that can be applied to the surface of objects to form a continuous, strong, protective, decorative, or special-performance solid film, play an extremely important role in modern life and industrial production. In the early days, coatings were mainly made from vegetable oils or natural lacquer, hence the common name "oil paint." With the booming development of the petrochemical industry and the continuous advancement of chemical synthesis technology, coatings today have long since transcended their traditional scope. Many products are now chemically synthesized, encompassing a wider variety of types and applications, making the term "coating" more appropriate. It includes various types such as water-based and oil-based paints, and is widely used as a key material in many fields such as construction, automobile manufacturing, shipbuilding, and furniture production. Different application scenarios place significantly different performance requirements on coatings. For example, architectural exterior wall coatings need good weather resistance and stain resistance, while automotive coatings have high requirements for gloss, hardness, and scratch resistance. To meet these diverse performance needs, the dilution process in coating production is crucial. A proper dilution ratio can adjust key indicators of the coating, such as viscosity, drying speed, and coating performance, thereby ensuring that the coating achieves the expected results during use.
[0003] Traditional paint dilution methods primarily rely on manual operation. Workers judge the paint-to-thinner ratio based on experience and manually add and stir. Firstly, manual operation has limited precision, making it difficult to guarantee consistent dilution ratios each time. Even experienced workers are affected by factors such as mood and fatigue, leading to performance variations between different batches of paint. This not only increases the difficulty of product quality control but may also reduce customer satisfaction. Secondly, manual stirring is inefficient and cannot meet the demands of large-scale industrial production. With technological advancements, some paint manufacturers have begun to adopt mechanized dilution equipment.
[0004] However, existing paint dilution equipment still has some shortcomings. Some equipment lacks precision in controlling the amount of thinner added, failing to meet the precision requirements of high-end paint production. It also cannot monitor various parameters during the dilution process in real time, such as dilution ratio and mixing uniformity, making it difficult to identify and resolve problems promptly. Furthermore, some equipment has an unreasonable stirring structure design, resulting in poor stirring effect and inadequate mixing of paint and thinner. This may lead to localized unevenness in the paint during use, affecting the quality and appearance of the coating. Therefore, it is necessary to design a paint dilution device for paint production.

Example
[0023] Based on the existing problems of inaccurate control of diluent addition and uneven mixing, the preferred embodiment of the paint dilution device for paint production provided by this utility model is as follows: Figure 1-4 The image shows a paint dilution device for paint production, comprising a support leg 1, a paint dilution cylinder 2 fixedly mounted on the top of the support leg 1, an arched base 11 on one side of the support leg 1, a top cover 3 fixedly mounted on the top of the paint dilution cylinder 2, a paint inlet pipe 4 connected to the top of the top cover 3, a discharge pipe 5 connected to the bottom of the paint dilution cylinder 2, and a control valve sleeved on the outer wall of the discharge pipe 5; a dilution water tank box 6 fixedly mounted on the top of the arched base 11, and a control box 7 fixedly mounted on the front of the dilution water tank box 6; and a stirring and dilution assembly 8, which is disposed inside the dilution water tank box 6 and inside and above the paint dilution cylinder 2; the stirring and dilution assembly 8 includes: a volume control dilution part 81, which is disposed inside the dilution water tank box 6 and above the paint dilution cylinder 2; and a stirring part 82, which is disposed above and inside the paint dilution cylinder 2, and above and to one side of the volume control dilution part 81.
[0024] The volume control dilution part 81 includes: a support plate 811, which is fixedly installed on one side of the outer wall of the dilution water tank box 6; a water pump 8113, which is set at the bottom of the inner wall of the dilution water tank box 6 via a support seat; an L-shaped support plate 812 is provided above the support plate 811, and the L-shaped support plate 812 is fixedly installed on the top of the top cover 3. An addition volume control sleeve 813 is fixedly installed on the top of the L-shaped support plate 812. The addition volume control sleeve 813 has a movable through hole 814 on its top, and the movable through hole 814 movably passes through the L-shaped support plate 812.
[0025] The movable perforation 814 is equipped with a control volume moving column 815. The outer wall of the control volume moving column 815 is fitted with a spring 816. The two ends of the spring 816 are respectively fixedly installed at the bottom of the L-shaped support plate 812 and the bottom of the control volume moving column 815. The top of the support plate 811 is fixedly installed with a lifting hydraulic cylinder 817, and the connecting end of the lifting hydraulic cylinder 817 is fixedly connected to the bottom of the control volume moving column 815 through the support column.
[0026] The top of the volume control moving column 815 is provided with a water inlet connecting groove 818, the inner wall of the water inlet connecting groove 818 is provided with a volume control water inlet hole 1 819, the outer wall of the volume control sleeve 813 is provided with a volume control water inlet hole 2 8110, and the volume control water inlet hole 1 819 and the volume control water inlet hole 2 8110 are compatible. The inside of the volume control water inlet hole 2 8110 is connected to a dilution water inlet pipe 8111, and the other end of the dilution water inlet pipe 8111 is connected to the top cover 3.
[0027] A control valve 8112 is fitted on the outer wall of the dilution inlet pipe 8111. The connection port of the water pump 8113 is connected to a telescopic delivery pipe 8114. The other end of the telescopic delivery pipe 8114 is connected to the interior of the water inlet connection groove 818. A sealing ring is fitted on the outer wall of the telescopic delivery pipe 8114 and is located on the top of the addition control sleeve 813.
[0028] Furthermore, this embodiment, by incorporating a lifting hydraulic cylinder 817, a flow control moving column 815, and a spring 816, can precisely adjust the relative positions of the water inlet connecting groove 818 and the flow control water inlet holes 1 and 2 8110. The lifting stroke of the lifting hydraulic cylinder 817 can be set via the control box 7 according to the type of paint, initial concentration, and target dilution ratio, thereby controlling the flow rate and total amount of diluent entering the paint dilution cylinder 2. This effectively avoids the problem of excessive or insufficient diluent addition due to human error or inaccurate valve adjustment. Simultaneously, the conveying section, composed of the conveying pump 8113, the telescopic conveying pipe 8114, and the control valve 8112, ensures stable diluent delivery. The telescopic conveying pipe 8114 can flexibly extend and retract during the lifting and lowering of the flow control moving column 815, ensuring the sealing and stability of the connection and preventing diluent leakage. Example
[0029] Please see Figures 1-4 Furthermore, based on Embodiment 1, the stirring part 82 includes: a motor 821, which is located above the top cover 3; a detection connecting pipe 828, which is connected to the outer wall of the paint dilution cylinder 2 and is used to extract the diluted liquid for detection; a stirring dilution rod 822 is provided at the output end of the motor 821 through a coupling, and the stirring dilution rod 822 movably passes through the top of the top cover 3 and extends into the interior of the paint dilution cylinder 2; a mounting cylinder 823 is fixedly installed at the bottom of the stirring dilution rod 822, and mounting rods 824 are fixedly installed at equal intervals around the outer circumference of the mounting cylinder 823.
[0030] A stirring ring 825 is fixedly installed at the other end of the mounting rod 824. An irregularly shaped connecting frame rod 826 is fixedly installed on the outer wall of the stirring and diluting rod 822 through the mounting ring. The irregularly shaped connecting frame rod 826 is symmetrically trapezoidal, and a stirring scraper 827 is sleeved on the outer wall of the irregularly shaped connecting frame rod 826.
[0031] Furthermore, in this embodiment, a motor 821 drives the stirring and dilution rod 822 to rotate at high speed, which in turn drives the mounting cylinder 823, mounting rod 824, stirring ring 825, irregular connecting frame rod 826, and stirring scraper 827 to work together. The stirring ring 825 forms a large-scale circumferential stirring flow field inside the paint dilution cylinder 2, which can quickly disperse the paint and diluent and accelerate the initial mixing of the two. With the help of the irregular connecting frame rod 826 and stirring scraper 827, they can move closely to the inner wall of the paint dilution cylinder 2, effectively preventing the paint and diluent from adhering and accumulating on the cylinder wall, ensuring that the material around the cylinder wall can also fully participate in the mixing, and avoiding the formation of mixing dead zones. At the same time, the detection and connecting pipe 828 can timely understand the dilution degree and mixing state of the paint, effectively reducing the waste of raw materials and the decline in production efficiency caused by unqualified dilution.
[0032] In use, the operator first injects the paint into the paint dilution cylinder 2 through the paint inlet pipe 4, while ensuring that the dilution water tank 6 contains sufficient thinner. Then, the operator sets the paint-to-thinner ratio parameters through the control box 7 and starts the device.
[0033] Furthermore, the volume control dilution section 81 operates first to precisely control the amount of diluent added. The lifting hydraulic cylinder 817 starts according to a preset program, pushing the volume control moving column 815 upward within the moving through hole 814 of the volume control sleeve 813. At this time, the spring 816 fitted on the outer wall of the volume control moving column 815 is compressed. When the volume control moving column 815 rises to a certain position, the volume control water inlet hole 819 on the inner wall of its top water inlet connecting groove 818 aligns with the volume control water inlet hole 8110 on the outer wall of the volume control sleeve 813, forming a connecting channel. At the same time, the conveying water pump 8113 at the bottom of the inner wall of the dilution water tank box 6 starts, pumping the diluent into the water inlet connecting groove 818 through the telescopic conveying pipe 8114. Since the volume control water inlet hole 819 and the volume control water inlet hole 8110 are connected, the diluent flows into the paint dilution cylinder 2 through the dilution water inlet pipe 8111. By controlling the lifting hydraulic cylinder 817 to push the control column 815 to its rising height and dwell time, the inflow of diluent can be precisely controlled to achieve the preset mixing ratio. When the amount added is sufficient, the lifting hydraulic cylinder 817 retracts, and under the elastic force of the spring 816, the control column 815 descends, causing the control water inlet hole one 819 and the control water inlet hole two 8110 to misalign, cutting off the diluent delivery channel and stopping the addition of diluent.
[0034] Furthermore, simultaneously with or after the addition of diluent at the controlled dilution section 81, the stirring section 82 begins operation. The motor 821 starts, its output driving the stirring dilution rod 822 to rotate. The stirring dilution rod 822, in turn, drives the mounting cylinder 823, mounting rod 824, and stirring ring 825 at the bottom to rotate together. The stirring ring 825 agitates the paint and diluent within the paint dilution cylinder 2, causing them to mix initially. Simultaneously, the irregularly shaped connecting frame rod 826 on the stirring dilution rod 822 drives the stirring scraper 827, which is fitted onto its outer wall, to rotate. The stirring scraper 827 adheres closely to the inner wall of the paint dilution cylinder 2, not only scraping off the paint adhering to the cylinder wall to participate in the mixing but also enhancing liquid convection, resulting in a more uniform mixture of paint and diluent.
[0035] During the dilution process, if it is necessary to test indicators such as the concentration of the diluted liquid, the diluted liquid in the paint dilution cylinder 2 can be drawn out through the detection connecting pipe 828 for testing. After the paint and thinner are fully mixed and homogeneous, the control valve on the outer wall of the discharge pipe 5 is opened, and the diluted paint is discharged from the discharge pipe 5 for subsequent production processes. Throughout the dilution process, the operator can monitor and adjust the operating status and parameters of each component in real time through the control box 7 to ensure that the paint dilution work is completed effectively and accurately.
[0036] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the 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 this utility model should be included within the protection scope of this utility model.
