Paper box drying equipment for compacting side interior

Abstract

The invention discloses paper box drying equipment for compacting the side interior. The paper box drying equipment structurally comprises a sealing door, conversion heat barrels, a displacement frame, a drying heat box and a distance adjusting head. The sealing door is hinged to the right side of the drying heat box. The four conversion heat barrels are arranged and vertically welded to the upperportion of the drying heat box and are arranged on the left side and the right side of a paper board correspondingly. A bottommost head end column is started and drives a bottom end column and a self-adaptation column to start to roll on the paper board, when the bottom end column and the self-adaptation column roll to the center, the bottom end column and the self-adaptation column can be contracted into the head end column, the two ends are staggered for rolling again, in the rolling process, an expanding groove can dry the paper board, grinding points can compress the paper board, the paper board can be compressed while being dried, the interior gap is fully filled when the water is evaporated to dryness, the paper board integrally becomes more compact, and after the paper board is folded into a paper box, more durability is achieved.

Description

technical field [0001] The invention relates to a carton drying device, in particular to a carton drying device with inner compaction on opposite sides. Background technique [0002] Cartons are widely used in packaging, industry, transportation, etc. The raw materials can be pure cardboard, composite boards with metal ions, or waterproof materials. Cartons are made by folding cardboard. As a result, the cardboard needs to be dried before folding to ensure the stability of the carton after folding. When drying the cardboard, a method similar to aeration is generally used, and the cardboard is placed in a hot air box for drying. [0003] Based on the above description, the inventors found that the existing carton drying equipment compacted on the opposite side mainly has the following deficiencies, such as: [0004] In the prior art, when the cardboard is dried, there will be gaps inside while the internal water vapor is evaporated, which will cause the force-bearing area of...

AI Technical Summary

Problems solved by technology

[0004] In the prior art, when the cardboard is dried, there will be gaps inside while the internal water vapor is evaporated, which will cause the force-bearing area of ​​the internal gaps to become smaller when the cardboard is folded, and the whole carton will easily collapse. , the folded carton has low strength, which affects the use of the carton
