Drying equipment for packaging boxes

Abstract

The invention relates to the field of packaging box processing equipment, in particular to drying equipment for packaging boxes. A microwave device of the drying equipment is installed at the leftmostend of a working table, a hot drying device is located in the middle of the working table, a heat dissipation section is located at the right end of the working table, the working table is provided with a conveyor belt, the left side of the conveyor belt is a packaging box drying inlet, and the right side of the conveyor belt is a packaging box drying outlet; a conveying belt is arranged betweenthe hot drying device and the heat dissipation section, is perpendicular to the working table and is connected with the conveyor belt for cooperative use; and an arc-control device is installed insidethe microwave device, the packaging boxes with small metal pieces can be dried in a microwave heating mode, the effect that the packaging boxes can be evenly dried is ensured, the product quality isimproved, and at the same time, electric arcs are prevented from damaging the microwave device. The reasonable layout of the microwave device and the hot drying device adapts to the drying requirements of different products, good effects of sterilization, mildew prevention and the like are achieved, and the situation that the boxes are affected with damp during sea transportation can also be avoided.

Description

technical field [0001] The invention relates to the field of packaging box processing equipment, in particular to a drying equipment for packaging boxes. Background technique [0002] After the packaging box is formed by colloidal adhesion, the box body needs to be heated and dried, and finally the products are collected and packed. The previous drying process uses hot air drying to dry the packaging box, but the existing hot air drying equipment cannot evenly blow the air to the product, resulting in uneven drying effect of the product. If the hot air blows directly to the The packaging box will also cause the product to be softened and affect the quality of the product. If microwave heating is used for drying, since most of the packaging boxes have metal flakes, when the conductor shields the electromagnetic field generated by the microwave oven, the charge will be redistributed on the surface of the conductor, resulting in a potential difference. If the potential differe...

The previous drying process uses hot air drying to dry the packaging box, but the existing hot air drying equipment cannot blow air evenly on the product, resulting in uneven drying effect of the product. If the hot air blows directly to The packaging box will also cause the product to be softened, affecting product quality

If microwave heating is used for drying, since most of the packaging boxes have metal flakes, when the conductor shields the electromagnetic field generated by the microwave oven, the charge will be redistributed on the surface of the conductor, resulting in a potential difference. If the potential difference is too large, it may break down the air and generate an arc. The inner wall of the equipment was damaged, so the method of microwave heating has not been applied to the drying process of the packaging box
