Wide-pressing area belt type calender

Abstract

The invention relates to a wide-pressing area belt type calendar which comprises a stand (11), wherein a heat roller (3) is installed on the stand (11); an upper press roller (5) is arranged on the heat roller (3); and the upper press roller (5) is installed on the stand (11) by a movable bearing seat (6). The wide-pressing area belt type calendar is characterized in that a first guide roller (2) is arranged at the oblique lower part of the heat roller (3); the first guide roller (2) is installed on the stand (11) by a first movable bearing device (1); a first steel belt (4) is surrounded between the first guide roller (2) and the upper press roller (5); the oblique upper part of the upper press roller (5) is provided with a second guide roller (8); the second guide roller (8) is installed on the stand (11) by a second movable bearing device (9); a second steel belt (10) is surrounded between the second guide roller (8) and the heat roller (3); and horizontal grooves are respectively arranged on the connecting positions of the stand (11) and the upper press roller (5) and the second guide roller (8). The invention has the advantages of wide press area, adjustable pressure and convenience for steel belt replacement.

Description

technical field [0001] The invention relates to a calender, in particular to a wide-nip belt-type calender, which is mainly used for the finishing process of continuous or discontinuous ironing of textiles and paper products, and improvement of smoothness, gloss and flatness. It belongs to the technical field of calender mechanical equipment. Background technique [0002] The calender is the supporting equipment of the glazing coating machine. After the paint layer coated on the surface of the printed matter is dried, it is then calendered by a calender, which can greatly improve the smoothness, gloss and flatness of the glazing coating. Existing calenders are generally two-roll calenders, and the two rolls are steel rolls and soft rolls. When working, only the deformation of the soft rolls is in contact. The nip between the two rolls is relatively narrow. The finished paper or fabric has uneven surface and insufficient smoothness, and the soft roll needs to be replaced fr...

AI Technical Summary

Problems solved by technology

Existing calenders are generally two-roll calenders, and the two rolls are steel rolls and soft rolls. When working, only the deformation of the soft rolls is in contact. The nip between the two rolls is relatively narrow. The finished paper or fabric has uneven surface and insufficient smoothness, and the soft roll needs to be replaced frequently

Chinese patent 200820037182.X discloses a double-belt calender, which uses two sets of belt calender rollers symmetrically arranged on the frame to increase the width of the nip, which solves the above problems, but because the two sets of belt calender rollers Symmetrical arrangement, the pressure between the two belts is small, and the pressure adjustment is difficult, and the pressure cannot be adjusted according to the production needs; in addition, if the steel belt is damaged, it is inconvenient to replace the steel belt
