[0002] Microchannel aluminum flat tube (also known as "parallel flow aluminum flat tube") is a thin-walled porous flat tubular material made of refined aluminum rods, hot extruded, and surface zinc sprayed for corrosion protection. It is mainly used in air-conditioning systems of various refrigerants. As a pipeline component carrying new environmentally friendly refrigerants, it adopts new environmentally friendly manufacturing and is the key material for the new generation of parallel flow microchannel air-conditioning heat exchangers.

[0003] In the manufacturing process of air-conditioning heat exchangers, after the microchannel flat tubes, fins and collecting tubes are assembled, brazing flux is sprayed on them, and then they are heated and welded into a core body in a heating furnace. The traditional roll coating method has a relatively single function. First, the impurities on the surface of the flat tubes need to be processed before roll coating to purify them. At the same time, after roll coating, they need to wait for drying before proceeding to the next step. Therefore, it is not convenient for this structure to be completed in one piece, and there are operational limitations. Utility Model Content

[0025] Please refer to Figures 1-4, the present utility model provides a technical solution: a roll coating mechanism for a microchannel flat tube, which includes: a roll coating box body 1. On both sides at one end of the top of the roll coating box body 1, motor boxes 3 are fixedly connected. Driven by the motor boxes 3, external gas is introduced. The entering gas is heated by a heating wire 2, and after heating, the gas is disordered by the rotation of a fan blade. The driving end of the motor box 3 is fixedly connected with a fan blade. Through the rotation of the fan blade, the gas is disordered and blown to the surface of the flat tube body 10 to complete the drying operation. A heating wire 2 is arranged at the bottom end of the fan blade, and the temperature is heated through the heating wire 2. The heating wire 2 is fixedly connected to the inner wall of the roll coating box body 1. A partition plate 4 is fixedly connected at the middle part inside the roll coating box body 1. Through the partition plate 4, heating and roll coating can be separated to prevent the sticking of the coating. A material cylinder 5 is arranged on one side of the partition plate 4, and the material cylinder 5 is fixedly connected to the roll coating box body 1. Fixing blocks 13 are fixedly connected to both the upper and lower ends on one side inside the roll coating box body 1. A threaded rod 14 is rotatably connected inside the fixing block 13. A scraping plate 12 is threadedly connected to the middle of the threaded rod 14. By pouring the flat tube body 10 into the inside of the roll coating box body 1 through the opening on one side, first, the upper surface of the flat tube body 10 abuts against the scraping plate 12, and its impurities can be scraped off. A brush roller 7 is rotatably fitted at the bottom end inside the material cylinder 5. The upper surface of the flat tube body 10 cooperates with the brush roller 7 to brush the coating onto the upper part of the flat tube body 10. An impurity collection box 8 is arranged on one side of the bottom end of the roll coating box body 1. After the gas enters the inside of the impurity collection box 8, due to the action of gravity, the impurities are stored inside the impurity collection box 8. An exhaust net 9 is fixedly connected to the other side of the bottom end inside the roll coating box body 1 for exhausting the gas.

[0026] The top end of the impurity collection box 8 is fixedly connected with an air inlet pipe 15. One end of the air inlet pipe 15 is fixedly connected with a dust suction pipe 18. One end of the dust suction pipe 18 is fixedly connected with a dust suction hood 11. The dust suction hood 11 sucks in the gas. After being sucked in, the gas flows through the dust suction pipe 18 to the air inlet pipe 15 and enters the inside of the impurity collection box 8. The dust suction hood 11 is located inside the scraping plate 12. Openings are provided at both ends of the roll coating box body 1. A support roller 6 is arranged at the bottom end of the opening, and both ends of the support roller 6 are fixedly connected to the roll coating box body 1. The flat tube body 10 is rollingly fitted above the support roller 6, and the flat tube body 10 abuts and cooperates with the scraping plate 12. A wind pump 17 is fixedly connected to one side of the top end inside the impurity collection box 8. The wind pump 17 pumps out the gas inside the impurity collection box 8 to reach a vacuum state. A filter screen 16 is arranged at the input end of the wind pump 17, and the filter screen 16 is movably connected to the impurity collection box 8.

[0027] Working principle: when in use, first pour the flat tube body 10 through the internal opening of the roller coating box 1 on one side. First, the upper surface of the flat tube body 10 contacts the shovel plate 12, which can scrape off the impurities. During the scraping process, the air pump 17 extracts the internal gas of the impurity collection box 8 to reach a vacuum state. At this time, the dust hood 11 sucks the gas, which flows to the air inlet pipe 15 through the dust suction pipe 18 after suction and enters the interior of the impurity collection box 8. Through the action of gravity, the impurities are stored in the interior of the impurity collection box 8. Then, the upper surface of the flat tube body 10 cooperates with the brush roller 7 to brush the paint to the top of the flat tube body 10. The flat tube body 10 continues to move toward one end of the roller coating box 1, and the motor box 3 drives it to introduce external gas. The incoming gas is heated by the heating wire 2. After heating, the fan blades rotate to confuse the gas and blow it to the surface of the flat tube body 10 to complete the drying operation. Then, the flat tube body 10 is discharged through one end of the roller coating box 1 to complete the roller coating operation.
