Description

Technical Field

[0001] This utility model relates to a paint spraying water spray booth, and more specifically, it relates to a paint spraying water spray booth. Background Technology

[0002] A paint spraying water shower booth (also commonly known as a "water shower test booth" or "artificial rain test booth") is indeed a device used to test the coating effect. It mainly simulates environmental conditions such as rain washing or long-term rain exposure to evaluate the coating's adhesion, water resistance, blistering resistance, and overall protective performance.

[0003] A paint spraying water shower booth is a device used to test the coating effect of paint. When conducting usage tests, actual rainfall is random (such as heavy rain, drizzle, intermittent rainfall), while water shower booths usually use a fixed flow rate and spray angle, which cannot simulate the diversity of real rainfall, and therefore cannot fully evaluate the waterproof performance of the paint.

[0004] Therefore, a new solution is needed to address this problem. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a paint spraying water spraying cabinet, which aims to solve the technical problem that the equipment cannot simulate the diversity of real rainfall.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a paint spraying water spraying cabinet includes a cabinet body, a U-shaped plate is fixedly installed at the front end of the cabinet body, an electric cylinder is fixedly installed on the upper left side of the U-shaped plate, a movable through plate is fixedly installed at the output end of the electric cylinder, the movable through plate is located in the U-shaped groove of the U-shaped plate, two fixed blocks are fixedly installed at the lower end of the movable through plate, a through pipe is movably connected to the opposite surfaces of the two fixed blocks, a plurality of water spray pipes are fixedly installed on the outer surface of the through pipe, a servo motor is fixedly installed at the right end of the right fixed block, the output end of the servo motor is fixedly installed to the right end of the through pipe, a water storage tank and a variable frequency water pump are fixedly installed at the upper end of the U-shaped plate, the variable frequency water pump is connected to the water storage tank, a flexible pipe is fixedly installed at the outlet of the variable frequency water pump, and the flexible pipe is fixedly connected to the through pipe.

[0007] The present invention is further configured such that: a guide rod is fixedly installed on the upper right side of the movable through plate, and the guide rod is movably interlocked with the top of the U-shaped plate.

[0008] The present invention is further configured such that: two fans are movably connected to the front side of the movable through plate, and the fans are located in front of the through pipe.

[0009] The present invention is further configured such that: a water collection box is fixedly installed at the lower part of the U-shaped groove of the U-shaped plate, and a water outlet pipe is fixedly connected to the right end of the water collection box.

[0010] In summary, this utility model has the following beneficial effects:

[0011] By using a variable frequency water pump to precisely adjust the water flow rate by changing the motor speed, the intensity of rainfall from heavy rain to drizzle can be accurately simulated, overcoming the limitation of traditional equipment that can only fix the flow rate. This allows for the simulation of the diversity of natural rainfall, ensuring more comprehensive and accurate test results. A servo motor drives the pipe and spray pipe to rotate at a certain angle, achieving 0-90° adjustment of the spray direction. This simulates non-vertical spraying scenarios caused by terrain or wind direction during actual rainfall. A fan provides wind power to simulate the wind speed and direction during natural rainfall, further improving the realism of the test and ensuring that the test results are consistent with actual usage conditions. This enhances the comprehensiveness of the evaluation of the waterproof performance of the coating. Attached Figure Description

[0019] The present invention will now be described in detail with reference to the accompanying drawings.

[0020] A paint spraying water spray booth, such as Figures 1 to 3 As shown, the system includes a cabinet 1. A U-shaped plate 2 is fixedly installed at the front end of the cabinet 1. An electric cylinder 3 is fixedly installed on the upper left side of the U-shaped plate 2. A movable through plate 4 is fixedly installed at the output end of the electric cylinder 3. The movable through plate 4 is located in the U-shaped groove of the U-shaped plate 2. Two fixed blocks 5 are fixedly installed at the lower end of the movable through plate 4. A through pipe 6 is movably connected to the opposite surfaces of the two fixed blocks 5. Several water spray pipes 7 are fixedly installed on the outer surface of the through pipe 6. A servo motor 8 is fixedly installed at the right end of the right fixed block 5. The output end of the servo motor 8 is fixedly installed at the right end of the through pipe 6. A water storage tank 9 and a variable frequency water pump 10 are fixedly installed at the upper end of the U-shaped plate 2. The variable frequency water pump 10 is connected to the water storage tank 9. A flexible pipe 11 is fixedly installed at the outlet of the variable frequency water pump 10. The flexible pipe 11 is fixedly connected to the through pipe 6.

[0021] like Figure 1 As shown, a guide rod 12 is fixedly installed on the upper right side of the movable tube plate 4. The guide rod 12 is movably interlocked with the top of the U-shaped plate 2. The guide rod 12 provides a guiding function. Its interlocking connection with the top of the U-shaped plate 2 can guide the movable tube plate 4 to move smoothly along a predetermined path, reduce shaking and deviation, and ensure the stability and consistency of the spraying process.

[0022] like Figure 1 As shown, two fans 13 are movably connected to the front side of the movable plate 4. The fans 13 are located in front of the pipe 6. The two fans 13 are installed in front of the movable plate 4 and in front of the water spray pipe 7. Driven by the front motor, the fans 13 can generate wind force of 0-5. When the spraying is in progress, the fans 13 start to simulate the effect of natural wind on rainfall: at low wind speed, the water flow direction is slightly deflected; at high wind speed, it forms an oblique spray and accelerates the water flow on the paint surface, realistically recreating the complex environment of rainstorm accompanied by strong wind.

[0023] A water collection box 14 is fixedly installed at the lower part of the U-shaped groove of the U-shaped plate 2. A water outlet pipe 15 is fixedly connected to the right end of the water collection box 14. The water after spraying falls into the water collection box 14 at the lower part of the U-shaped plate 2 and is discharged to the external recycling system through the water outlet pipe 15 to avoid water accumulation affecting the operation of the equipment.

[0024] Working principle: A spray gun is used to evenly spray paint onto the front side of cabinet 1. Water is stored in the water tank 9. A variable frequency water pump 10 is electrically connected to an external power supply via an external control switch group. The pump 10 draws water from the tank 9 and delivers it through a flexible pipe 11 to the connecting pipe 6, finally spraying it out from the spray pipe 7. The flexible pipe 11 has good flexibility and corrosion resistance, allowing it to adapt to the up-and-down movement of the movable connecting plate 4 without affecting water flow. The connecting pipe 6 is fixed below the movable connecting plate 4, and multiple spray pipes 7 are installed on its outer surface to evenly spray water onto the coating panel to be tested. The water pump 10 adopts variable frequency speed control technology. Its working principle is as follows: by changing the frequency of the input power supply, the motor speed is adjusted, thereby controlling the output flow of the variable frequency water pump 10. When simulating heavy rain, the frequency is increased to increase the flow, so that the water spray pipe 7 sprays out a high-speed water flow; when simulating drizzle, the frequency is reduced to decrease the flow, forming a fine water mist. The water spray pipes are evenly distributed on the surface of the through pipe 6. The water flow delivered by the variable frequency water pump 10 is distributed to each water spray pipe through the through pipe to ensure the uniformity of spraying. By adjusting the flow rate, the amount of water sprayed on the front side of the cabinet 1 per unit time can be directly controlled to achieve precise control of the rainfall intensity.

[0025] A servo motor 8 is fixedly installed on the right end of the right-side fixing block 5. The output end of the servo motor 8 is fixedly installed on the right end of the pipe 6. The servo motor 8 drives the pipe 6 to rotate, thereby driving the water spray pipe 7 to adjust its angle. The servo motor drives the pipe 6 to rotate within ±45° within the fixing block 5 through high-precision rotation control. When the pipe 6 rotates, the spray direction of the water spray pipe 7 changes accordingly, which can simulate non-vertical spraying scenarios such as crosswind rainfall and directional heavy rainfall. For example, rotating the pipe 6 clockwise can make the spray direction deflect to the right side of the cabinet 1, simulating... In real-world environments, due to wind-induced shifts in rainfall, the electric cylinder 3 pushes the movable plate 4 vertically up and down along the U-shaped groove of the U-shaped plate 2 via its telescopic movement. When the movable plate 4 moves down, the overall position of the water spray pipe 7 decreases, and the spraying area shifts from the top of the cabinet 1 to the middle or bottom, allowing the water spray pipe 7 to cover different height areas. This ensures that all parts of the coating surface receive sufficient spray testing. By adjusting the height of the electric cylinder 3, the coating can be tested at different heights, avoiding some areas from not being fully tested and improving the accuracy of the test results.

[0026] Two fans 13 are installed on the front side of the movable plate 4, in front of the water spray pipe 7. Driven by the front motor, the fans 13 can generate wind force of 0-5. When the spraying is in progress, the fans 13 start to simulate the effect of natural wind on rainfall: at low wind speed, the water flow direction is slightly deflected; at high wind speed, it forms an oblique spray and accelerates the water flow on the paint surface, realistically recreating the complex environment of rainstorm accompanied by strong wind.

[0027] In summary, the variable frequency water pump 10 precisely adjusts the water flow rate by changing the motor speed, accurately simulating the rainfall intensity from heavy rain to drizzle, overcoming the limitation of traditional equipment that can only fix the flow rate, simulating the diversity of natural rainfall, and ensuring more comprehensive and accurate test results. The servo motor 8 drives the through pipe 6 and the spray pipe 7 to rotate at a certain angle, realizing the spray direction adjustment from 0-90°, simulating the non-vertical spraying scenario caused by terrain or wind direction in actual rainfall. The fan 13 provides wind power, simulating the wind speed and direction during natural rainfall, further improving the realism of the test, ensuring that the test results are consistent with actual use, and improving the comprehensiveness of evaluating the waterproof performance of the coating.

[0028] It is worth noting that the servo motor 8 disclosed in the above embodiments is specifically a Panasonic MINAS A6 series, the electric cylinder 3 is specifically a Festo EGC series, and the variable frequency water pump 10 is specifically a Grundfos CR series. The external control switch group and the external power supply control the operation of the servo motor 8, the electric cylinder 3, and the variable frequency water pump 10 adopt the methods commonly used in the prior art.

All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
