[0002] Paper packaging occupies an important position in the circulation of modern commodities. With the continuous growth of market demand and consumers' increasing requirements for product information identification, a coding device for paper packaging production has come into being. In traditional paper packaging production, the methods of identifying product information are often relatively simple, such as handwriting or using simple seals. These methods are not only inefficient, but also difficult to ensure the clarity and accuracy of the identification. With the advancement of science and technology, coding technology has gradually been introduced into the field of paper packaging production. In the production process of cartons, in order to facilitate people's identification, it is necessary to spray code on the cartons. When spraying code on the cartons, the coding device is one of the indispensable components.

The telescopic support rod 910 drives the limit slider 98 to slide in the limit slide frame 95 and stretch the reset spring 97, so that the toggle plate 94 can adapt to cartons of different thicknesses and align them. When the cartons on the conveyor belt 7 pass through the pressing plate 913, the friction force drives the pressing plate 913 and the rolling column 91 to rotate around the axis of the rolling column 91. When the rolling column 91 rotates, it drives multiple groups of pressing plates 913 to squeeze the surface of the cartons in turn, so that the cartons on the conveyor belt 7 can be pressed, and the vacuum pump 991 and the electric heating wire inside the heating tube 992 are turned on. The vacuum pump 991 draws external gas into the heating tube 992. 92, the incoming gas is heated by the electric heating wire inside the heating tube 992, the heated gas enters the exhaust pipe 994 from the connecting pipe 993, enters the outlet pipe 997 through the movable pipe 995, and is finally blown out from the outlet pipe 997 to dry the coded cartons on the conveyor belt 7.
