Description

Technical Field

[0001] The utility model relates to the technical field of packaging bag printing, in particular to a printing device for packaging bag production. Background Art

[0002] Plastic packaging bags are made of plastic and are used to produce various daily necessities. They are widely used because of their small size and portability. However, they are also listed as one of the sources of white pollution because of their difficulty in degradation. In the production of traditional packaging bags, various logos are often printed on their surfaces to promote their products or advertisements due to their high circulation. However, when printing packaging bags, due to their light weight and the easy generation of static electricity on the surface after friction, wrinkles are easily generated on the surface during transportation before printing, which affects the printing effect. After searching, the patent document with the publication (announcement) number: CN218366975U discloses a printing device for packaging bag production, including a smoothing device, which is arranged inside a box body and can smooth the surface of the packaging bag waiting to be printed. The smoothing device mainly includes an extrusion wheel and a release rod. The central axis of the extrusion wheel is rotatably connected with an inclined rod. The printing device for packaging bag production is provided with a smoothing device. When the electric hydraulic rod moves downward, it will drive the extrusion wheel to roll and smooth the surface of the packaging bag below. At the same time, the inclined rod will also open to both sides under the extrusion accordingly. Finally, the inclined rods on both sides will also be attracted to the surface of the magnetic block due to the attraction of the magnetic block. At this time, the electric hydraulic rod moves upward, thereby driving the inclined rods on both sides to move upward synchronously. At this time, the inclined rod will be separated from the attraction between the magnetic block due to the extrusion of the release rod, and the reset spring will also pull the inclined rods on both sides to reset again, thereby smoothing the packaging bag below.

[0003] The existing printing equipment is not convenient to tighten the packaging bag during printing, and the rolling flattening is adopted, which will cause wrinkles in the packaging bag during printing, resulting in poor printing effect. Utility Model Content
