Description

Technical Field

[0001] The present application relates to the technical field of printing technology, and in particular to an anti-rust film printing device. Background Art

[0002] Anti-rust film is a material synthesized from polyethylene, VCI anti-rust particles, anti-rust oil and other ingredients. It is mainly used to package some metal devices that are prone to rust. Modern high-precision machinery needs to be protected with relatively high quality during transportation, so anti-rust film plays a vital role.

[0003] Printing is a technology that transfers ink from originals such as text, pictures, photos, anti-counterfeiting, etc. to the surface of materials such as paper, textiles, plastics, leather, PVC, PC, etc. through processes such as plate making, inking, and pressurization, in order to batch reproduce the contents of the originals. The printing device is a mechanical device used to complete these processes.

[0004] The anti-rust film printing device can realize accurate printing of patterns, texts, images, etc. on the surface of the anti-rust film. Compared with the traditional spraying or engraving methods, the anti-rust film printing device can ensure clear patterns, bright colors, and better durability.

[0005] For example, patent publication number CN214934585U specifically discloses a film printing device, which uses a printing roller in a printing box for printing, and uses a first electric push rod to drive a first connecting plate and a second connecting plate to adjust the height of the printing roller, and uses a first motor at the first connecting plate to drive a first rotating rod to rotate, so that the printing roller can be effectively rotated, and a rotating roller arranged at the first support plate is used to support the film, so that the flatness of the film can be maintained while the film is being transmitted, thereby facilitating efficient printing and avoiding printing creases.

[0006] However, in the above patent, a rotating roller at a fixed position is used to support the film to maintain the flatness of the film. However, during the printing process of the film, due to the different tightness or thickness of the film when it is rolled up, when the film passes through the rotating roller, the rotating roller cannot be adjusted according to the actual situation of the film, so that the tension on the film is too large or too small.

[0007] Therefore, it is necessary to provide a rust-proof film printing device to solve the above problems.

[0044] A fourth roller 12 is mounted on a bearing near the winding roller 3 on the mounting frame 4, and a second roller 10 and a third roller 11 are mounted on bearings on both sides of the upper end of the mounting frame 4, so that the second roller 10, the third roller 11 and the fourth roller 12 can guide the conveyance of the film and form a transmission path for the film together with the unwinding roller 2 and the winding roller 3;

[0045] like Figure 2 and Figure 3 As shown, a tensioning mechanism 7 is installed on a bearing at a position of the mounting frame 4 close to the unwinding roller 2, and the tensioning mechanism 7 is used to tension the film released by the unwinding roller 2, so that the printed film has fewer wrinkles and improves printing accuracy;
