Description

Technical Field

[0001] The utility model relates to a packaging bag spray painting device, belonging to the technical field of packaging bags. Background Art

[0002] Packaging bags are an indispensable part of our daily life. They are not just containers for loading items, but also have multiple functions such as protecting goods, facilitating transportation and storage. According to their uses, they can be divided into food bags, supermarket bags, medical bags, etc. Each type of packaging bag has its specific advantages and application scenarios.

[0003] A Chinese public patent (publication number: CN 209521416 U) discloses a spray painting device on a snack packaging bag production device, including a base, a bracket fixedly connected to the upper end of the base, a spray painting trolley installed on the bracket, a groove on the base, a guide rail installed inside the groove, a slider installed on the guide rail, a roller box fixedly connected to the upper end of the slider, a fixed plate and a support block fixedly connected to the base, a motor installed on the fixed plate, and a roller fixedly connected to one end of the motor shaft. The utility model can fix the snack packaging bag in the roller box by installing a roller box and fixing the movable roller in the roller box to one end of the knob to prevent the snack packaging bag from deviating and causing poor spray painting. By fixing the roller box to the slider and installing an elastic rubber ring on the roller, the device can be suitable for fixing and rolling snack packaging bags of various sizes;

[0004] Although the above-mentioned equipment can effectively prevent the snack packaging bag from shifting during inkjet printing and causing poor inkjet printing by clamping the snack packaging bag in the roller box, the above-mentioned equipment still has certain defects.
