Hot air drying equipment for corrugated case printing machine

Abstract

The invention discloses hot air drying equipment for a corrugated case printing machine. The hot air drying equipment structurally comprises a draught fan, side supporting plates, a dehumidification pipe, control panels and a drying box, wherein the draught fan is fixedly installed at the top of the drying box, the side supporting plates are welded to the side ends of the drying box, and the dehumidification pipe is fixedly installed at the upper ends of the side supporting plate in an embedded manner. In the drying process, hot air is guided into conduction pipes through air inlets in the front ends of connecting supporting plates, so expansion films expand and swell, at the moment, the angle between swinging plate bodies increases, the four outer sides of a corrugated plate are propped open, magnetic attraction is carried out through second magnetic blocks on laminating plates and first magnetic blocks, meanwhile the laminating plates rotate around positioning shafts, when the laminating plates are attached to the surfaces of the swinging plate bodies, collision plates and the surfaces of the swinging plate bodies maintain laminating strength, the traction on the outer side on the corrugated plate is improved, large shrinkage occurring to the corrugated plate in the drying process is prevented, and ink printing gelatinization of the corrugated plate during drying is avoided.

Description

technical field [0001] The invention relates to the field of corrugated carton machinery, and more specifically, relates to a hot air drying device for a corrugated carton printing machine. Background technique [0002] Corrugated box is the most widely used packaging product. During the production of corrugated boxes, it is necessary to mark the surface of the corrugated cardboard, transfer ink from the printing plate to the corrugated cardboard, and the printed corrugated cardboard needs to pass The hot air drying equipment dries the ink on its surface, but when drying the corrugated cardboard with printing on multiple sides, the corrugated cardboard is directly put into the hot air drying equipment, resulting in different drying strengths on multiple sides of the corrugated cardboard, resulting in multiple corrugated cardboards. The degree of shrinkage of the surface is different, resulting in different degrees of ink shrinkage on each board surface, and the bottom surfac...

[0002] Corrugated box is the most widely used packaging product. During the production of corrugated boxes, it is necessary to mark the surface of the corrugated cardboard, transfer ink from the printing plate to the corrugated cardboard, and the printed corrugated cardboard needs to pass The hot air drying equipment dries the ink on its surface, but when drying the corrugated cardboard with printing on multiple sides, the corrugated cardboard is directly put into the hot air drying equipment, resulting in different drying strengths on multiple sides of the corrugated cardboard, resulting in multiple corrugated cardboards. The degree of shrinkage of the surface is different, resulting in different degrees of ink shrinkage on each board surface, and the bottom surface of the corrugated cardboard is in direct contact with the placement board inside the hot air drying equipment, which is likely to cause the ink printing on the bottom surface of the corrugated cardboard to gel when drying. Reduce the clarity of ink printing on the surface of corrugated cardboard after drying
