Description

Technical Field

[0001] The present invention relates to the technical field of environmentally friendly paint coating, and more specifically, to an environmentally friendly paint coating device and coating method based on a roller coating process. Background Art

[0002] In modern industrial production, paint coating is one of the important processes to improve product appearance quality and extend service life. Roller coating process, as the core technology of surface treatment, is widely used in industrial coating of metal, wood, plastic and other substrates. Traditional paint coating methods such as spraying and brushing have problems such as large material waste, serious environmental pollution and uneven coating. Roller coating process, as an efficient and environmentally friendly coating method, has been widely used in recent years.

[0003] However, traditional roller coating equipment still faces some challenges in practical applications. The material is prone to deviation or instability when entering the coating area, which affects the coating accuracy. For substrates that need to be puttyed first, traditional equipment is difficult to automatically and evenly add the putty layer. The unused paint is directly discharged or wasted, which not only increases the cost but also pollutes the environment. The coated material takes a long time to dry naturally, which affects production efficiency and has high energy consumption. Therefore, it is of great significance to develop an efficient and environmentally friendly paint coating device that can solve the above problems. Summary of the invention

[0015] An environmentally friendly coating coating method based on a roller coating process comprises:

[0016] The material is placed on the surface of the guide seat, and the distance between the second guide plate and the first guide plate is adjusted by starting the third electric telescopic rod to adapt to materials of different sizes. Then the fifth servo motor starts its output shaft to rotate and drives a guide wheel to rotate under the action of the bevel gear. At this time, the multiple guide wheels are rotated under the action of the multiple first gears and the second gears, so as to transport the material;

[0017] The output shaft of the first servo motor is started to drive a conveyor roller to rotate, and at this time, multiple conveyor rollers are driven to rotate under the action of the conveyor belt, thereby driving the material to be transported. While the conveyor belt moves, the first auxiliary roller presses it, and the output shaft of the sixth servo motor is started to drive the putty roller to rotate. At this time, putty powder can be applied to the surface of the material. However, when the coating thickness needs to be adjusted, the first electric telescopic rod is started, and the piston rod of the first electric telescopic rod drives the first sliding seat to move on the surface of the first guide rail, thereby adjusting the height of the first protective shell and the putty roller;

[0018] The heating mixing box and the fourth servo motor are started, and the heating mixing box heats the paint inside it. At the same time, the output shaft of the fourth servo motor rotates to drive the mixing shaft and the mixing blade to rotate, thereby mixing and stirring the paint to make the paint evenly heated. Then the booster pump is started to extract the paint inside the heating mixing box and transport it to the spray pipe through the material guide pipe;

[0019] The paint falls on the surface of the paint roller through the spray head, and the second servo motor and the third servo motor are started at the same time. The second servo motor and the third servo motor respectively drive the paint roller and the scraper roller to rotate, and the paint roller will apply the paint on the surface of the material, and then the scraper roller will scrape out the excess paint. When it is necessary to adjust the height of the paint roller, the second electric telescopic rod is started, and the piston rod of the second electric telescopic rod drives the second sliding seat to move on the surface of the second guide rail, thereby driving the paint roller and the scraper roller to adjust the height. At the same time, the conveyor belt is driven to rise under the action of the second pulling roller, and the remaining paint will fall on the surface of the collecting bucket, and then the paint will enter the inside of the discharge inclined plate through the guide bucket, and fall into the inside of the spring telescopic rod under the action of the discharge inclined plate;

[0020] The paint falling into the screening frame will pass through the screening net under the action of gravity, and at the same time, the vibration motor starts and drives the screening frame to move back and forth longitudinally under the action of the fourth mounting seat and the spring telescopic rod, thereby increasing the probability of the paint passing through the screening net, and then the paint enters the interior of the heating mixing box;

[0021] After coating is completed, the unloading conveyor belt transports the material. The electric opening and closing door on one side is opened. At this time, the unloading conveyor belt moves the material to the bottom of the UV lamp, and closes the electric opening and closing door. The material is irradiated by the UV lamp and UV-cured. At the same time, the first blower and the second blower are started and the air inside the curing box is cooled down by the action of the air duct. After curing is completed, the electric opening and closing door on the other side is opened, and the unloading conveyor belt will continue to transport the material.

[0022] 3. Beneficial effects

[0023] Compared with the prior art, the advantages of the present invention are:

[0024] (1) The present invention can guide the material through the guiding mechanism, and then the conveying mechanism can transport the material. At the same time, the coating mechanism can coat the surface of the material with putty powder, and then the coating mechanism can coat the surface of the material with environmentally friendly paint. At the same time, the feeding mechanism can continuously transport the paint. After the coating is completed, the unloading conveyor belt can transport the material, and the curing mechanism can UV cure the material.

[0025] (2) The present invention ensures that the material always maintains a stable position during the coating process through the setting of the guiding mechanism, avoids deviation, and improves the coating accuracy. Through the setting of the coating mechanism, putty powder can be coated on the surface of the substrate, thereby ensuring that the surface of the material is flat and consistent, reducing manual intervention and improving work efficiency. Through the setting of the feeding mechanism, unused paint can be collected and filtered and returned to the feeding system, thereby minimizing waste, reducing environmental pollution, and saving resources. Through the setting of the curing mechanism, the drying time of the coated material is shortened, the production efficiency is improved, and the energy consumption is reduced.

While the conveying belt 103 moves, the first auxiliary roller 106 presses it. The sixth servo motor 207 is started to drive the putty roller 206 to rotate through its output shaft. At this time, the surface of the material can be coated with putty powder. However, when the coating thickness needs to be adjusted, the first electric telescopic rod 204 is started. The piston rod of the first electric telescopic rod 204 drives the first sliding seat 202 to move on the surface of the first guide rail 201, thereby adjusting the height of the first protective shell 205 and the putty roller 206.

[0058] By starting the heating mixing box 401 and the fourth servo motor 404, the heating mixing box 401 will heat the paint inside it, and at the same time, the output shaft of the fourth servo motor 404 rotates to drive the mixing shaft 402 and the mixing blade 403 to rotate, so as to mix and stir the paint so that the paint is heated evenly. Then, the booster pump 405 is started to extract the paint inside the heating mixing box 401 and transport it to the spray pipe 407 through the guide pipe 406;

[0059] The paint falls on the surface of the paint roller 306 through the spray head 408, and the second servo motor 308 and the third servo motor 309 are started at the same time. The second servo motor 308 and the third servo motor 309 respectively drive the paint roller 306 and the scraper roller 307 to rotate, and the paint roller 306 will apply the paint on the surface of the material, and then the scraper roller 307 will scrape out the excess paint. When it is necessary to adjust the height of the paint roller 306, the second electric telescopic rod 304 is started, and the piston rod of the second electric telescopic rod 304 drives the second sliding seat 302 to move on the surface of the second guide rail 301, thereby driving the paint roller 306 and the scraper roller 307 to adjust their heights. At the same time, the conveyor belt 103 is driven to rise under the action of the second pulling roller 311, and the remaining paint will fall on the surface of the collecting bucket 107, and then the paint will enter the inside of the discharge inclined plate 109 through the guide bucket 108, and fall into the inside of the spring telescopic rod 409 under the action of the discharge inclined plate 109;

[0060] The paint falling into the screening frame 411 will pass through the screening net 412 under the action of gravity, and at the same time, the vibration motor 413 is started and drives the screening frame 411 to move back and forth longitudinally under the action of the fourth mounting seat 410 and the spring telescopic rod 409, thereby increasing the probability of the paint passing through the screening net 412, and then the paint enters the interior of the heating mixing box 401;

[0061] After coating is completed, the unloading conveyor belt 7 transports the material, and the electric opening and closing door 602 on one side is opened. At this time, the unloading conveyor belt 7 moves the material to the bottom of the UV lamp 605, and closes the electric opening and closing door 602. The material is irradiated by the UV lamp 605 and UV-cured. At the same time, the first blower 606 and the second blower 607 are started and the air inside the curing box 601 is cooled down by the action of the air duct 608. After curing is completed, the electric opening and closing door 602 on the other side is opened, and the unloading conveyor belt 7 will continue to transport the material.
