Description

Technical Field

[0001] This utility model relates to the field of water-based paint temperature control, and in particular to a temperature control system for the water-based paint coating process. Background Technology

[0002] Water-based paints, as environmentally friendly coatings, are widely used in furniture manufacturing, panel processing, and hardware coating due to their low emissions of volatile organic compounds (VOCs) and their friendliness to humans and the environment. The spray coating process is one of the core processes in water-based paint application. It involves continuously spraying water-based paint evenly onto the surface of a workpiece to form a smooth and even coating. The quality of this coating directly determines the aesthetic appearance and lifespan of the workpiece.

[0003] In the water-based paint spraying process, temperature is a key parameter affecting coating quality and production stability. The viscosity, flowability, and film-forming properties of water-based paints are extremely sensitive to temperature changes: if the temperature is too low, the viscosity of the paint increases and the flowability decreases, easily leading to uneven coating thickness, sagging, or pinhole defects during spraying; if the temperature is too high, the evaporation rate of water in the paint accelerates, which not only makes the spray curtain prone to breakage but also forms problems such as orange peel and bubbles on the coating surface. It may also cause premature cross-linking of the paint components, affecting coating adhesion. Furthermore, temperature fluctuations in the spraying environment, the temperature of the water-based paint storage tank, and the temperature during the pre-drying stage after spraying can further exacerbate the instability of coating quality.

[0004] When cooling water-based paint, when low-temperature water is injected from the bottom, the heat of the water-based paint in the inner tank is carried away through heat conduction. Since the density of cold water is greater than that of hot water, when cold water is injected into the tank, it will naturally sink to the bottom of the tank due to its higher density, while the density of hot water will naturally rise to the top of the tank due to its lower density. When cold water is injected from the bottom, it will push the hot water in the tank to move upward, forming convection. This convection helps to cool the liquid in the entire tank evenly. The existing technology still has the following problems when used: When water is injected from below, the water in the interlayer flows out from above. The water flow in the upper corner is weaker, resulting in a slower water flow rate in that area. Consequently, the cooling water temperature in this area is higher, which affects the cooling effect of the cooling water on the paint in the inner tank. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology, this utility model provides a temperature control system for water-based paint coating process, which can solve the following technical problems: when water is injected from below and the water in the interlayer flows out from above, the water flow in the upper corner is weak, which will result in a slower water flow rate in this area, resulting in a higher cooling water temperature in this area, thus affecting the cooling effect of the cooling water on the water-based paint in the inner tank.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a water-based paint coating process temperature control system, including an outer tank and an inner tank, with a sandwich layer formed between the outer tank and the inner tank. Cooling water is injected into the sandwich layer through a cooling water inlet. A water outlet groove is provided on the outer side of the top of the outer tank, allowing the cooling water in the sandwich layer to be discharged from the water outlet groove. An inclined plate is fixed to the outer side of the outer tank below the water outlet groove, and a water-proof cover is fixed to the edge of the inclined plate. The water-proof cover can be welded to the outer tank and can cover the water outlet groove inside. A cooling water outlet is provided at the lowest point of the water-proof cover. The cooling water in the sandwich layer is evenly discharged through the water outlet groove, collected at the lowest point by the inclined plate, and discharged through the cooling water outlet.

[0007] As a preferred embodiment of this utility model, the water-proof cover includes a top plate, which is welded to the outside of the outer tank and located above the water outlet trough. Annular baffles are provided at the edges of the top plate and the inclined plate.

[0008] As a preferred embodiment of this utility model, the inner can is internally connected to a first paint outlet and a second paint outlet. Both the first paint outlet and the second paint outlet extend outward a certain distance after passing through the outer can, and are sealed at the contact point with the outer can.

[0009] As a preferred embodiment of this utility model, the top surfaces of the outer tank and the inner tank are on the same horizontal line, and a sealing rubber is provided on the top surface. The top surface of the outer tank is fixed with a top cover by bolts.

[0010] As a preferred embodiment of this utility model, the top surface of the top cover is provided with a paint sampling port and an exhaust port, and the paint sampling port and the exhaust port are provided with plugs.

[0011] As a preferred embodiment of this utility model, a paint can is fixed to the inner bottom wall of the inner can, a paint guide tube is provided inside the paint can, a filter screen is sleeved on the outside of the paint guide tube, and the filter screen is placed on top of the paint can and fixed by a fixing nut.

[0012] As a preferred technical solution of this utility model, the paint guide tube has a high and wide paint inlet, the paint inlet is welded to the middle part of the paint can, and the bottom end of the paint inlet extends downward through the outer can and the inner can and then extends downward a certain distance.

[0013] As a preferred embodiment of this utility model, a plug is provided at the top opening of the paint injection port.

[0014] Compared with the prior art, the beneficial effects that this utility model can achieve are: Low-temperature cooling water is injected into the jacket through the cooling water inlet to remove the temperature inside the inner tank. As the cooling water is injected, the high-temperature water above flows down through the water outlet channel, is received and guided by the inclined plate, and is then discharged through the cooling water outlet, thus achieving the function of evenly discharging the warm water above.

[0016] To make the technical means, creative features, and achieved objectives and effects of this utility model easier to understand, the present utility model is further described below with reference to specific embodiments. However, the following embodiments are merely preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described in the implementation are all within the protection scope of this utility model without creative effort. Example

[0017] Please refer to Figures 1-4 As shown, this utility model provides a temperature control system for water-based paint coating processes, including an outer tank 1 and an inner tank 15. A paint tank 16 is disposed inside the inner tank 15, and a paint inlet 12 extends through the interior of the paint tank 16. Multiple paint outlet holes 17 are opened on the outer side of the paint inlet 12, such as... Figure 4As shown, the paint outlet 17 is welded to the outer tank 1, inner tank 15, and paint tank 16, thus initially fixing the outer tank 1, inner tank 15, and paint tank 16. The bottom of the paint inlet 12 extends a certain distance through the outer tank 1 and connects to external paint injection equipment for a stable supply of water-based paint. A filter screen 18 is fitted on the outside of the paint inlet 12, and a fixing nut 19 is screwed onto the outside of the paint inlet 12. The fixing nut 19 can fix the filter screen 18 to the top of the paint tank 16. The filter screen 18 can be a filter screen with a frame. After the water-based paint is filtered, it flows between the inner tank 15 and the paint tank 16. The frame can support the filter screen to ensure the stability of the filter screen 18 installation. At the same time, a rubber gasket is set between the filter screen 18 and the top of the paint tank 16 for sealing. A sealing rubber ring is set between the filter screen 18 and the paint inlet 12. The outer side of the inner tank 15 is provided with a first paint outlet 2 and a second paint outlet 11. The first paint outlet 2 and the second paint outlet 11 can penetrate the outer tank 1 and extend outward for a certain distance. The first paint outlet 2 and the second paint outlet 11 are both welded to the outer tank 1. During the painting process, water-based paint enters the interior of the paint tank 16 through the paint inlet 12 and the paint outlet 17. The water-based paint level inside the paint tank 16 gradually increases and enters the space between the inner tank 15 and the paint tank 16 after passing through the filter screen 18. It is then transported to the water-based paint delivery pipeline through the first paint outlet 2 and the second paint outlet 11. like Figures 1-4 As shown, the top surfaces of the outer tank 1 and the inner tank 15 are on the same horizontal plane, and the outer tank 1 and the inner tank 15 are provided with a top cover 8. The contact surfaces of the outer tank 1 and the inner tank 15 with the top cover 8 are provided with sealing rubber 6, and the top cover 8 is connected to the outer tank 1 by bolts passing through it, thereby fixing the top cover 8. An exhaust port 9 is provided in the center of the top cover 8, and a paint sampling port 7 is provided on the top surface of the top cover 8. The paint sampling port 7 leads to the interior of the paint tank 16 and is used by staff to collect samples of water-based paint. like Figures 1-4 As shown, a cooling water inlet 13 is provided at the bottom of the outer side of the outer tank 1. The cooling water inlet 13 is used to inject low-temperature cooling water. The cooling water enters the interlayer between the outer tank 1 and the inner tank 15. As the water level rises, the cooling water continuously overflows from the outlet trough 14 opened on the outer side of the outer tank 1 and flows onto the inclined plate 3 welded to the outer side of the outer tank 1. A top plate 5 is welded to the outer side of the outer tank 1. The top plate 5 is located above the outlet trough 14. An annular baffle 4 is welded between the top plate 5 and the inclined plate 3. The annular baffle 4 blocks the overflowing cooling water. Since the inclined plate 3 has a certain slope, the bottom of the annular baffle 4 also has a certain slope. A cooling water outlet 10 is installed on the lower side of the annular baffle 4 to discharge the heated cooling water. The cooling water inlet 13 and the cooling water outlet 10 are connected to a chiller through a liquid transfer pipe and are linked together. The chiller circulates and cools the cooling water, and the chiller temperature can be set. The cooling water is cooled by a chiller and then fed into the jacket through pipes and cooling water inlet 13. Because the temperature of the chilled water is high, it will push the heated cooling water upwards, causing it to overflow from the outlet tank 14 and then be poured back into the chiller through the cooling water outlet 10 for further cooling. This circulation process achieves the cooling of the water-based paint.
