Printing roller offset fuzzy prevention assembly for food packaging materials

Abstract

The invention relates to the technical field of food packaging materials, and discloses a printing roller offset fuzzy prevention assembly for food packaging materials. The printing roller offset fuzzy prevention assembly comprises a support frame, a power device is fixedly connected to the outer side of the top of the support frame, a rotating shaft is rotatably connected to the top of the power device, an anti-offset mechanism is rotatably connected to the middle of the rotating shaft, a hot stamping roller is movably connected into the anti-offset mechanism, and a hot stamping plate is movably connected to the bottom of the hot stamping roller. According to the printing roller offset fuzzy prevention assembly for the food packaging materials, the anti-offset mechanism is installed between the power device and the hot stamping roller, when the hot stamping roller jumps, a rolling ball extrudes a trigger supporting hand, so that the trigger supporting hand drives an extrusion sleeve and an extrusion rod to move towards the inner side, then a stabilizing head makes contact with a special-shaped groove, therefore, jumping rotation of the rotating shaft is limited, the unbalance state of the hot stamping roller is adjusted, and hot stamping images and texts on the outer side of plastic are clearer.

Description

technical field [0001] The invention relates to the technical field of food packaging materials, in particular to a food packaging material used for preventing offset and blurring of printing rollers. Background technique [0002] At present, plastic packaging materials account for more than 30% of all kinds of packaging materials, second only to paper products. In my country's food packaging materials, the application of plastics has exceeded 50% of the total food packaging materials, ranking first among all kinds of packaging materials, and printing on food materials can better play a role in publicity and attract consumers to buy. [0003] Printing is to add exquisite appearance to plastic products. Plastic printing mainly includes two parts, one is hot stamping of large pieces of printing paper on plastic products, and the other is small-area spray printing, which is done by hand. They all use stamping paper for hot stamping, but during the hot stamping process, the rel...
