Description

Technical Field

[0001] This utility model relates to the field of cardboard drying technology, and in particular to a drying component for cardboard processing. Background Technology

[0002] In the production of cardboard boxes, the boxes need to be processed through multiple steps such as gluing, flattening, and laminating. These steps require the use of glue and water with high humidity, so the cardboard boxes are prone to moisture and deformation during the production process. Drying the cardboard boxes can quickly remove the moisture, allowing the boxes to return to their original shape and improving production efficiency.

[0003] In document CN212902485U, a multi-angle drying device for cardboard box processing includes a lower box with an exhaust vent at its front end. An upper box is detachably connected to the upper part of the lower box, and a control box is fixedly connected to the front end of the upper box. A heat dissipation door is located on the left side of the upper box, and heat exhaust vents are located on both the left and right sides of the upper end of the upper box. An air inlet is fixedly connected between the heat exhaust vents. This multi-angle drying device for cardboard box processing adopts a mature drying method, using a perforated conveyor belt to dry and bake the cardboard boxes from the bottom, thus overcoming the inherent drying blind spots of existing equipment. An adjustable opening structure allows for adjustment of the drying airflow within the box, controlling the gas flow rate and ensuring efficient drying.

[0004] Existing drying equipment for cardboard box processing, when using hot airflow to dry cardboard boxes, has several drawbacks. For a single top-mounted drying unit, the hot airflow is difficult to cover the bottom of the cardboard for drying, resulting in poor drying effect. For a dual-airflow drying unit, the bottom and top hot airflows can easily create turbulent airflows within the drying chamber, causing the cardboard to shift and become displaced. This is not conducive to the normal transport of cardboard by traditional conveyor belt structures and increases the frequency of equipment maintenance.

[0005] To address the above problems, a drying assembly for cardboard box processing is proposed. Utility Model Content
