[0038] A dust suction pipe 7 inserted into the groove is fixedly installed on one side of the dust suction box 4, and two hoses 8 connected to the brush plate 2 are fixedly installed on the surface of the dust suction pipe 7;

[0039] A material feeding mechanism is provided on one side of the UV printer body 1 , and a clamping mechanism for fixing the winding drum is provided on one side of the UV printer body 1 .

[0040] During use, the winding drum is installed and fixed by the clamping mechanism, and the material drum is fixed and discharged by the feeding mechanism, so that the material passes through the two brush plates 2 and is fixed to the winding drum. At the same time, the distance between the two brush plates 2 is adjusted by the adjusting mechanism so that the brush plates 2 are in contact with the upper and lower surfaces of the material. The two print heads in the UV printer body 1 cooperate with the winding drum to rotate to collect the material for double-sided printing. During the process, the brush plates 2 are used to clean the impurities and dust attached to both sides of the material. At the same time, the fan 5 forms a negative pressure in the dust suction box 4, and the cleaned dust and impurities are sucked into the dust suction box 4 through the dust suction hole 3, the hose 8 and the dust suction pipe 7, and collected through the collecting drawer 6. The impurities and dust can be processed by subsequently extracting the collecting drawer 6. Therefore, the impurities and dust attached to the surface of the material can be cleaned, and the impurities and dust are prevented from affecting the printing and curing effects of the material, thereby effectively improving the printing quality and efficiency of the material.
