Description

Technical Field

[0001] This utility model relates to the field of automatic printing technology for film materials, and more specifically, to an automatic inkjet printing device for film materials. Background Technology

[0002] In automated packaging production workshops, thermal transfer printing or laser printing is typically used for printing on PE film surfaces. Thermal transfer printing requires ribbon changes, which increases process input and leads to frequent ribbon replacements in automated systems, impacting production efficiency. Laser printing, on the other hand, is quick and convenient, but it can damage the film surface and cause dust pollution. Therefore, existing technologies have further incorporated inkjet printing equipment for this purpose.

[0003] For example, the patent with publication number CN220332299U discloses a PE film printing machine that feeds the film material into a printing box and uses multiple printheads for printing. After printing, ultraviolet lamps are used to quickly cure the dye sprayed onto the PE film, thereby achieving rapid drying of the pattern on the PE film. However, since the surface of PE film material is usually relatively smooth, although ultraviolet lamps are used to further cure and stabilize the pattern after printing, there is still a possibility that the printed part will be scratched during subsequent conveying or rolling.

[0004] Based on the above description, there is an urgent need for an automatic inkjet printing device for film materials that can ensure the printed pattern is stable and not easily scratched off. Utility Model Content

[0005] The purpose of this invention is to provide an automatic inkjet printing device for film materials, which aims to solve the technical problem that the printed pattern has poor stability when applied to PE film due to the smooth surface of the film material.

[0008] Preferably, the conveying mechanism includes a horizontal feed roller group and a horizontal discharge roller group; the horizontal feed roller group and the horizontal discharge roller group are respectively located at both ends of the frame; the plasma processor is suspended at the end of the horizontal feed roller group close to the horizontal discharge roller group; the drying mechanism is located at the end of the plasma processor away from the horizontal discharge roller group; and the first curing mechanism is located between the drying mechanism and the plasma processor.

[0009] Preferably, one end of the plasma processor is connected to the frame via multiple first lifting rods; the other end of the plasma processor extends toward the horizontal feed roller group.

[0010] Preferably, the horizontal feed roller group is lower than the horizontal discharge roller group; a tensioning roller is sandwiched between the horizontal feed roller group and the horizontal discharge roller group.

[0011] Preferably, the first curing mechanism includes a horizontal ultraviolet lamp plate and an inclined ultraviolet lamp plate; the horizontal ultraviolet lamp plate is located at one end of the plasma processor near the tensioning wheel; the inclined ultraviolet lamp plate is located at one end of the horizontal ultraviolet lamp plate near the tensioning wheel; the irradiation surface of the inclined ultraviolet lamp plate is parallel to the conveying surface of the tensioning wheel.

[0012] Preferably, the printing mechanism is suspended at one end of the horizontal discharge roller group near the first curing mechanism; the second curing mechanism is located at the end of the printing mechanism away from the first curing mechanism.

[0013] Preferably, the frame is provided with a spray box at one end away from the horizontal feed roller; the horizontal discharge roller group includes multiple discharge rollers; the spray box is located between a pair of discharge rollers; and the printing mechanism is inserted into the interior of the spray box via a second lifting rod.

[0015] The technical solution of this utility model embodiment has at least the following advantages and beneficial effects:

[0016] This invention uses a drying mechanism to pre-dry the film material at the feed end and remove impurities. Then, a plasma processor is used to treat the surface of the film material, making the surface rough and removing static electricity to facilitate printing by the printing mechanism. After the plasma processor treatment, the film material is further cured and dried by a first curing mechanism, and then printed by the printing mechanism. After printing, it is sent to a second curing mechanism for further curing, finally completing the automatic printing of the film material. The printed images and text have high stability and are not easily scratched. Attached Figure Description

[0026] In this embodiment, the film material is fed into the frame 1 from one end via the conveying mechanism 2 and exited from the other end. During its passage through the frame 1, the film material is processed sequentially by the drying mechanism 3, the plasma processor 4, the first curing mechanism 5, the inkjet printing mechanism 6, and the second curing mechanism 7 to complete the automatic printing process.

Subsequently, it is further cured and dried by the tilted UV lamp plate 52, so as to facilitate clearer printing later.
