AI Technical Summary

Technical Problem

Existing paper product printing drying equipment, when using drying gas to blow on the surface of paper products, is prone to causing the edges of the paper products to flip up. Incompletely dried ink is scratched by adjacent parts or the paper products themselves, affecting the quality of the printed product.

Method used

The system uses a drying chamber, an air supply unit, and multiple sets of drying pipes to dry paper products thoroughly and efficiently with drying gas. At the same time, the suction fan of the adsorption mechanism generates negative pressure, which is used to adsorb the paper products through the air holes on the conveyor belt, keeping them flat and preventing the edges from turning over.

Benefits of technology

It achieves rapid and uniform curing of ink, improves the quality of printed products, reduces the accumulation of harmful gases in the equipment, and improves the working environment.

Abstract

This application relates to a paper printing dryer, comprising: a support frame; two side plates disposed opposite to each other at the top of the two support frames; a conveyor disposed between the two side plates; the conveyor including a conveyor belt with multiple ventilation holes; a drying chamber disposed between the tops of the two side plates; multiple sets of drying pipes disposed inside the drying chamber; and an air supply unit disposed on the drying chamber; and an adsorption mechanism comprising a housing disposed between the two side plates; multiple exhaust fans disposed inside the housing. This application, through the combined use of the drying chamber, the air supply unit, and the multiple sets of drying pipes, can comprehensively and efficiently dry the ink on paper products. The negative pressure generated by the exhaust fans of the adsorption mechanism adsorbs the paper products through the ventilation holes, effectively preventing the edges of the paper products from turning over due to gas blowing, thus improving the quality of the printed products.
