Humidifying device of calender

Abstract

The invention discloses a humidifying device of a calendar. The humidifying device of the calendar comprises a steam box, the steam box is arranged at the position between a first calender and a second calender, the steam box is of a cylindrical structure, the axis of the cylinder is parallel to the axis of the first calender and the axis of the second calender, the steam box is provided with an upward air outlet which is parallel to the axis of the steam box, the axial width of the air outlet is identical with the width of a paper web, the air outlet is arranged below paper, supporting arms are arranged at the two ends of the upper portion of the steam box, the supporting arms are connected with a rack through a supporting structure, one end of the steam box is provided with an air inlet, the air inlet is connected with a steam inlet pipe, a condensed water outlet is formed in the other end of the steam box and connected with a water outlet pipe, the steam inlet pipe is provided with a steam flow control valve, and the water outlet pipe is provided with a condensed water outlet valve. Steam is sprayed to the surface of paper through small openings, moisture on the surface of the water is improved, the smoothness of the paper surface during subsequent calendaring is increased, and product quality is improved.

Description

technical field [0001] The invention relates to the technical field of papermaking equipment, in particular to a humidifying device for a calender. Background technique [0002] In the paper production process in the prior art, paper products require high smoothness, but after soft pressing and calendering, the smoothness cannot meet the technical standard requirements, and even the smoothness of the paper surface after passing through the calender If it is too small, it will fail to meet the product quality requirements, produce substandard products or even waste products, cause losses to production, and also affect the economic benefits of the enterprise. Contents of the invention [0003] The purpose of the present invention is to solve the above-mentioned problems existing in the prior art, and to provide a calender humidifying device; the present invention makes the paper humidify with steam before passing through the second calender, so that the moisture content of t...
