With the continuous expansion of the application field of inkjet printing, the printing of double-layer materials like paper bags is more and more popular. Most duplex material printing today still uses a solution of air suction devices in combination with battens. According to the method, the air suction cavity and the belt corresponding to the opening of the air suction cavity are arranged below the jet printing module, the pressing strip is arranged in front of the jet printing module, when a material is located on the belt, the air suction sucks the lower layer of the material, the material moves forward along with the belt, and the pressing strip presses the upper layer of the material when the material reaches the lower portion of the pressing strip, so that the upper layer of the material can be pressed down to a certain extent, but the pressing strip cannot be arranged below the spray nozzle, after the material leaves a range pressed by the pressing strip, the material still becomes high, as the deformation degree of each material is different, the distance from the material to the surface of the spray nozzle is different, the spray nozzle is easily scratched due to too close distance, the surface of the material is polluted due to light weight, the spray nozzle is scratched, the spray nozzle is damaged due to too far, printing content caused by flying ink is not real, the printing effect is seriously affected, and the defective rate of products is increased.
