Description

Technical Field

[0001] The utility model relates to the technical field related to packaging bag processing, and is provided with a curing device for food packaging bag printing production. Background Art

[0002] Bag curing, also known as bag curing, involves placing the laminated film into a curing chamber to allow the main agent and curing agent of the polyurethane adhesive to react. The primary purpose of curing is to allow the main agent and curing agent to fully react within a specified timeframe to achieve optimal composite strength. A secondary purpose is to remove residual low-boiling-point solvents. Traditional curing chambers typically consist of a box housing two winding rollers. The bottom of the box features a pipe carrying hot steam or hot oil, connected to a steam or kerosene-fired boiler that provides the required heat. During operation, the bag is wrapped around the two winding rollers. The rotation of one of the rollers pulls the bag from one winding roller to the other, evenly heating the stretched bag and completing the curing process. However, this curing method requires workers to monitor each curing chamber individually to prevent bags in one chamber from being fully cured while the winding rollers are idle. This wastes energy, slows production, increases labor costs, and results in a poor user experience.

[0003] Application number CN202120092992.0 discloses a packaging bag aging device, comprising a housing, comprising an outer housing, an inner housing disposed within the outer housing, a plurality of connecting blocks fixedly connected between the outer and inner housings, each of which has a ventilation hole in the middle, four universal wheels with a locking function fixedly connected to the lower side of the housing, an air inlet and an air outlet fixedly connected to the upper side of the housing, and two bag winding devices disposed within the inner housing, one of which has an observation device disposed on its lower side. By providing the outer and inner housings, the utility model can form a cavity between the outer and inner housings, helping to maintain the temperature within the housing and achieving better packaging bag aging. Furthermore, by providing the bag winding device and the observation device, the user can be alerted after the packaging bag is wound, thus avoiding production delays.

[0004] Although the utility model proposed above can form a cavity between the outer box and the inner box by arranging the outer box and the inner box, which helps to maintain the temperature in the box and make the packaging bag curing effect better, and at the same time, by arranging the bag winding device and the observation device, the user can be reminded after the packaging bag is rolled up to avoid production delays, but there is a shortcoming that the device described above is not yet able to perform curing treatment on all different types of packaging bags. This requires the two second guide rollers inside the frame to move downward through the driving mechanism, thereby increasing the length of the packaging bag passing through the box at the same time, and then increasing the time the packaging bag passes through the box, thereby increasing the curing time of the packaging bag, and then being able to adjust the curing time of the packaging bag to ensure the curing effect on different types of packaging bags, thereby improving the scope of application of the curing device.
