Lifting type suspension drying machine

Abstract

The invention discloses a lifting type suspension drying machine which comprises a machine frame, lifting mechanisms, air nozzles and bellows. A conveying mechanism is disposed inside the lower end of the machine frame, and paper operates from left to right through the conveying mechanism. The machine frame has multiple sections, and the bellows are disposed in each section of machine frame. The bellows is divided into an upper bellows and a lower bellows. The upper bellows and the lower bellows are arranged at the upper end and the lower end of the conveying mechanism respectively. The lower end of the upper bellows and the upper end of the lower bellows are connected with a row of air nozzles. The upper portion of the front side of each section of machine frame is provided with a fan. The lifting mechanism is correspondingly disposed in the upper bellows or the lower bellows of each section of machine frame. The bellows are designed to be of a vertically movable structure, the interval between the air nozzles and the paper can be regulated precisely, paper drying efficiency is improved, and the lifting type suspension drying machine is also suitable for drying paper-based materials of different thicknesses. Due to unique air nozzle design, outlet air can operate along a curved surface, so that tension on the paper is reduced, and the paper is protected from breakage caused by too high stress.

Description

technical field [0001] The invention relates to a drying machine, in particular to a lifting suspension drying machine. Background technique [0002] The horizontal impregnation and drying production line mainly uses urea-formaldehyde resin and phenolic glue to impregnate, glue, dry and stack paper-based materials. When the existing drying equipment dries the impregnated paper-based material, the drying air duct and the upper and lower air nozzles in the equipment are all in a fixed production and assembly mode. When the distance between the air nozzle and the paper is too small, it is not conducive to paper threading. It is not conducive to paper drying when it is too large, so it is not suitable for drying paper-based materials with different thicknesses; in addition, the original nozzle structure adopts asymmetrical nozzles, which directly blow to the surface of the paper, and the wind is easy to make the paper Broken, the wind is small and the drying effect is not ideal...
