Description
Technical field
The present invention relates to a kind of soft boots pressure device of toilet paper machine and its application, belong to tissue Machines technical field.
Background technology
With the high speed development of paper-making industry, the high speed of paper machine speed is lifted, and has higher to want press section dehydrating effect
Ask, and the application of shoe press technology just substantially improves dewatering of the paper machine under the conditions of high-speed cruising.Shoe press is
The transient behavior of roll press is dehydrated, the long-time width pressure area dehydration being changed under static pressure, is a kind of wide nip press.With tradition
Squeezing is compared, and the pressure area of shoe press is the several times of traditional pressure area.Due to the characteristic, under the conditions of identical speed, page exists
The residence time of boot-shaped pressure area is the several times of traditional pressure area, while shoe press can obtain higher line pressure, be a kind of introversion
Face pressure area, is face contact form.So shoe press helps to improve page dehydration efficiency, the curing of paper web is more advantageous to, is made
Paper web obtains more preferable intensity before the drying, so that press section obtains more preferable runnability, and water content in paper web
Reduce, steam consumption is also greatly saved.
Traditional boots pressure device is generally made of boots roller, counter-pressure cylinder, load locking and some auxiliary elements, wherein boots roller
Major part is made of boots plate, swivel head, crossbeam, bearing block etc., and it is boots set that flexible material is set with outside boots roller.The roller core of boots roller is
Static and non-rotating, whole boots roller does not have driving device in itself；Overcoat-boots set of flexible material is set with outside roller core, boots set passes through
Pressing plate is installed on the special bearing of roller core, and boots set is only rotary part；Boots plate is the core of shoe press, its one end
Special hydraulic cylinder is connected to, they are fixed on the beam inside boots roller together, and boots plate is to counter-pressure cylinder under the action of oil cylinder
Apply pressure.Hydraulic oil is injected into the recessed groove between pressure shoe and boots set by oilhole special in pressure shoe.
Since the design of these recessed grooves is very unique, make to produce a floor height pressure oil film between boots plate and boots set, and in high pressure oil-film force
The effect learned and under fluid dynamic effect, support, lubricate and cool down boots plate and boots set.This Liquid Lubrication Condition can make
Friction substantially prolongs the service life of boots set in the degree that power consumption is low, abrasion is extremely slight, reduce at the same time
Energy consumption.
Traditional boots pressure device is mainly used in the manufacturing of cardboard, wrapping paper and filing paper etc., its dehydrating effect compared with
To be advanced, it has huge superiority in terms of longitudinal pressure, separately adjustable nip width and line pressure is changed.However, defending
During the manufacturing of raw paper, traditional boots pressure device is with regard to helpless, this is because production toilet paper is different from paperboard
Or Cultural Paper, toilet paper pliability require high, and require certain air permeability, this allow for toilet paper should have in dry-pressing area compared with
High aridity, while line pressure cannot be excessive, the line pressure of toilet paper is generally required in below 170N, and traditional boots pressure device
Line pressure generally in 700-1000N, the pliability requirement of toilet paper production can not be met since pressure is excessive.Therefore, having must
Design a kind of soft boots pressure device suitable for toilet paper machine production.
