Description

Technical Field

[0001] The utility model relates to the technical field of printing devices, in particular to a double-sided printing composite film printing device. Background Art

[0002] Composite membrane is a separation membrane with a microporous membrane or ultrafiltration membrane as a support layer, and a dense homogeneous membrane with a thickness of only 0.1 to 0.25 μm as a barrier layer on its surface. The structural design of this membrane greatly increases the amount of material that can pass through it. Double-sided printing of composite membrane is mainly the process of printing design patterns, texts, etc. on the surface of the composite membrane.

[0003] The existing double-sided printing composite film printing device also has the following problems. The existing device generally prints on the composite film roll after fixing it. Referring to a film double-sided printing device disclosed in the patent application with reference to publication number CN219749215U, in this utility model, the static electricity on the surface of the film body can be eliminated by the static electricity removal component, thereby reducing the adhesion of dust, and then the dust removal component is used to remove dust from the surface of the film body, thereby preventing the influence of dust adhesion on printing, and then the cooling component is used to cool the film body to prevent the printing surface from being worn by directly rolling it up after printing.
