The invention discloses an EPS foam packing box production process. The EPS foam packing box production process comprises pre-foaming, curing and forming procedures, wherein in the curing procedure, EPS foam particles are conveyed to a pressure-loading tank; hot air of which the pressure is 0.4-0.6 kilogram force per square centimeter and the temperature is 35-45 DEG C is injected into the tank body of the pressure-loading tank; the pressure and the temperature of hot air in the tank body are kept unchanged, and the EPS foam particles are stored for 0.5-1 hour; hot air is injected into the tank body again, thereby increasing the internal pressure of tank body to 0.8-1.2 kilogram force per square centimeter; the internal pressure and temperature of the tank body are kept unchanged, and the EPS foam particles are stored for 0.8-1.2 hours; hot air is injected into the tank body for the third time, thereby increasing the internal pressure of tank body to 1.8-2.2 kilogram force per square centimeter; and the internal pressure and temperature of the tank body are kept unchanged, the EPS foam particles are stored for 0.8-1.2 hours, and then the curing treatment is completed. According to the EPS foam packing box production process, a pressurizing and warming mode is adopted for the curing treatment, the curing effect is good, and the cell internal negative pressure recovery rate reaches 99%.

The invention discloses an EPS temperature-increasing pressurizing curing process. The EPS temperature-increasing pressurizing curing process comprises the steps that EPS particles are conveyed to a pressure-loading tank; hot air of which the pressure ranges from 0.4 kgf / cm<2> to 0.6 kgf / cm<2> and the temperature ranges from 35 DEG C to 45 DEG C is injected into the pressure-loading tank; the pressure and temperature of the hot air in a tank body remain unchanged, and the EPS particles are stored for 0.5 h to 1 h; the hot air is injected into the pressure-loading tank again, and the pressure in the tank body is increased to 0.8 kgf / cm<2> to 1.2 kgf / cm<2>; the pressure and temperature in the tank body remain unchanged, and the EPS particles are stored for 0.8 h to 1.2 h; the hot air is injected into the pressure-loading tank again, and the pressure in the tank body is increased to 1.8 kgf / cm<2> to 2.2 kgf / cm<2>; the pressure and temperature in the tank body remain unchanged, the EPS particles are stored for 0.8 h to 1.2 h, and curing of the EPS particles is completed. Curing treatment is conducted on EPS in a temperature-increasing pressurizing mode, the curing effect is good, and the negative pressure recovery rate in cell reaches 99%.

The invention relates to the technical field of packaging composite curing, in particular to a packaging composite curing treatment method and system, comprising a curing box, a top wall of the curing box is provided with a mounting plate, two sides of the mounting plate are mounted with gears that maintain meshing relationship, and the gears are respectively inclined A fixed cylinder is installed at the bottom through a fixed connection arm, and a movable cylinder is arranged inside the fixed cylinder. There are two winding rollers, and the outer sides of the two winding rollers on the same side are connected by the belt surface of the same packaging bag. The invention solves the problem that the food packaging bag is heated unevenly due to the change of position, which eventually leads to poor curing effect of the packaging bag. The proposed curing treatment device can improve the curing effect of the food packaging bag, and the working efficiency of the curing process is significantly improved, which is beneficial to improve the quality of the final product.
