2. The transfer film flowing to the water surface of the transfer tank is subjected to an ink dissolving solution deodorization treatment before entering the transfer area 44. The method specifically comprises the following steps: the deodorizing device is provided with a deodorizing liquid box 46, a deodorizing fan 47, a deodorizing filter screen 48, a deodorizing air pipe 49 and the like, wherein the deodorizing liquid box 46 can be arranged on the left side and/or the right side, a deodorizing cover 50 is arranged above the transfer printing groove 44, the deodorizing liquid box 46 is positioned below the right side of the deodorizing cover 50, a safety door 51 is arranged above the left side of the deodorizing cover 50, an electric control door 52 is arranged below the left side of the deodorizing cover 50, and a display touch screen 28 is arranged on the electric control door 52.

The design of the invention is characterized in that the transfer printing film is unreeled from a transfer printing film support frame, passes through a space between an ink solution passive film pressing roller and an ink solution driven roller under the guidance of a transfer printing film guide roller, the ink solution driven roller coats the ink solution on the transfer printing film, and then the transfer printing film is transmitted and output on a conveying track; compared with the traditional ink solution spraying mode, the printing ink solution passive film pressing roller is used for adhering the printing ink solution from the printing ink solution remaining groove, the adhering uniformity of the rolling surface of the printing ink solution passive film pressing roller is good, and after the transfer film passes through the space between the printing ink solution passive film pressing roller and the printing ink solution passive wheel roller, the printing ink solution is uniformly coated on the transfer film, so that the water transfer printing quality is improved, and the higher product surface effect is realized.

Secondly, a plurality of uniformly distributed concave points are arranged on the rolling surface of the ink solution driven wheel roller, and the uniform ink solution is left on the ink solution driven wheel roller under the action of an elastic scraper; the transfer printing film spring tension automatic adjusting rod is arranged, so that the wrinkle of the film paper is relieved, the surface of the film is smooth, the solution is more uniform when being rolled and coated, and the thickness of the film is consistent; under the operation of the film pressing wheel, the transfer printing film is synchronous with the conveying track, so that the film and the conveying track cannot slip, the flow film is stable and smooth, and the reliability is good. And in the launching process of the transfer printing film, the transfer printing film cannot wrinkle after launching due to the action of the three-surface guiding air openings, and the wrinkled films are naturally separated according to three directions, so that the smooth flowing of the transfer printing film in water is ensured.

Moreover, the method for rolling and coating the flow film by the ink solution has reasonable process flow arrangement, ensures good controllability of the flow film process, is stable in flow film, is not easy to cause equipment failure or poor products, is environment-friendly and tasteless, and improves the working environment of workshop staff.

The above description is only a preferred embodiment of the present invention, and is not intended to limit the technical scope of the present invention, so that any minor modifications, equivalent changes and modifications made to the above embodiment according to the technical spirit of the present invention are within the technical scope of the present invention.
