[0029] The working principle of all the contents in the above embodiments is as follows:

[0030] During use, first place the material on the conveying roller 3 inside the processing frame 2 to make it move uniformly into the box body 1. At this time, the cleaning cylinder 7 on the processing frame 2 sweeps the impurities attached to the surface of the material to make the attached impurities loose. Then, the larger loose impurities are blocked in front of it by the staggered scraping plates 8 to prevent the larger impurities from entering the box body 1. Subsequently, use an external blower to blow the wind through the air inlet pipe 20 into the air outlet box 11. Then start the external drive to drive the semi-gear 17 to rotate. The semi-gear 17 drives the rack 16 engaged with it to reciprocate. Thus, the sliding plate 13 reciprocates inside the slide rail 12. During this process, the sliding plate 13 drives the air regulating plate 15 to swing, and under the action of the return spring 19, the air regulating plate 15 can be made to swing left and right, so as to blow the surface of the material, and the smaller impurities on the surface of the material are blown onto the blanking plates 9 on both sides of the processing frame 2. At the same time, under the blocking action of the scraping plates 8, the smaller impurities are prevented from floating to the rear end position of the material. Thus, the impurities are discharged outside the processing frame 2 through the blanking port 10;

[0031] The cleaned material enters the box body 1 under the action of the conveying roller 3. Then, the PETG decorative film on the feeding roller 6 is wound around another feeding roller 6 through the adjusting roller 5. Subsequently, start the electric push rod 23 to push the mounting frame 21 to rotate, so that the roller 24 on one side of the mounting frame 21 fits on the top of the PETG decorative film and squeezes the PETG decorative film to fit down on the surface of the material. Immediately afterwards, make the heating pipe 25 work and transfer the heat to the outer surface of the roller 24 to heat the PETG decorative film, so as to make it fit on the surface of the material, and thus complete the hot pressing work of the PETG decorative film. Subsequently, the material is transported to the outside of the box body 1 through the conveying roller 3 and the limiting roller 4.
