Dual-pressure stepless pressure regulation roller calender

Abstract

The invention relates to a dual-pressure stepless pressure regulation roller calender which comprises a cloth inlet device, a cloth outlet device, a rack, a heating mirror surface roller, a stepless pressure regulation roller, a rubber bent roller and a cooling water roller, wherein the stepless pressure regulation roller comprises a roller core, a roller sleeve, a nylon sleeve, a side-surface sealing strip, an end-surface sealing ring and a bearing. Through adoption of the calender, continuous secondary calendering can be performed on the single side of fabric, different styles can be rolled without replacing the nylon roller, the production efficiency is improved, the energy is saved, and the production cost is reduced.

Description

technical field [0001] The invention relates to a roller calender, in particular to a double-pressure stepless pressure-regulating roller calender used in the printing and dyeing industry. Background technique [0002] The existing calender generally adopts ordinary fixed medium-high three-roll calender, including cloth feeding device, cloth discharging device, frame, heated mirror roller, fiber roller and mirror roller, heated mirror roller, fiber roller and mirror roller They are all arranged on the frame, wherein the heated mirror roll is set above the fiber roll, the mirror idler roll is set below the fiber roll, and the heated mirror roll is connected to the oil cylinder; when the calender is working, the heated mirror roll Calendering of the fabric by heating mirror rolls and fiber rolls; when two conventional rolls are pressed together, bending occurs, that is, the linear pressure is higher at the ends of the rolls than in the middle, in which case it cannot Correspo...

[0002] The existing calender generally adopts ordinary fixed medium-high three-roll calender, including cloth feeding device, cloth discharging device, frame, heated mirror roller, fiber roller and mirror roller, heated mirror roller, fiber roller and mirror roller They are all arranged on the frame, wherein the heated mirror roll is set above the fiber roll, the mirror idler roll is set below the fiber roll, and the heated mirror roll is connected to the oil cylinder; when the calender is working, the heated mirror roll Calendering of the fabric by heating mirror rolls and fiber rolls; when two conventional rolls are pressed together, bending occurs, that is, the linear pressure is higher at the ends of the rolls than in the middle, in which case it cannot Corresponding to a variety of calendering pressures, the best effect can only be produced when a certain pressure is used, so that when using the same cloth to produce different styles, it is necessary to change different rolls; and for different In order to produce the same style of cloth, different rolls must be changed, and multiple tests must be carried out on the nylon rolls to determine the ideal style after rolling out; this requires more equipment, more time, and more More manpower and more cost can finally find a suitable calendering process, which undoubtedly brings a lot of troubles to calendering manufacturers; and when some fabrics need to be calendered twice on one side, the fabric needs to be re-calendered. Put it into the calender and go through it again for the second calendering, so its production efficiency is low, and energy consumption and labor costs increase at the same time
