Description
Technical field
The utility model is related to a kind of soft boots pressure devices of toilet paper machine, 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 promoted, and has higher want to press section dehydrating effect
It asks, and the application of shoe press technology just substantially improves dewatering of 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, it is more advantageous to the solidification of paper web, is made
Paper web obtains better intensity before the drying, to make press section obtain better runnability, and water content in paper web
It reduces, 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, entire boots roller itself is without driving device；Housing-boots set of flexible material is set with outside roller core, boots set passes through
Pressing plate is mounted 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
It is connected to special hydraulic cylinder, they are fixed on together on the beam inside boots roller, and boots plate is to counter-pressure cylinder under the action of oil cylinder
Apply pressure.Hydraulic oil is injected by oilhole special in pressure shoe in the recessed groove between pressure shoe and boots set.
Since the design of these recessed grooves is very unique, a floor height pressure oil film is generated between so that boots plate and boots is covered, and in high pressure oil-film force
And the effect that under fluid dynamic effect, support, lubrication and cooling boots plate and boots cover.This Liquid Lubrication Condition can make
The degree that friction is low in power consumption, abrasion is extremely slight, therefore the service life of boots set is substantially prolonged, reduce simultaneously
Energy consumption.
Traditional boots pressure device is mainly used in the manufacturing of cardboard, wrapping paper and filing paper etc., dehydrating effect compared with
To be advanced, it has huge superiority in terms of changing longitudinal pressure, separately adjustable nip width and line pressure.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 dry-pressing area should have compared with
High aridity, while line pressure cannot be excessively high, the line pressure of toilet paper is generally required in 170N hereinafter, and traditional boots pressure device
Line pressure generally in 700-1000N, the pliability requirement of toilet paper production is cannot be satisfied since pressure is excessive.Therefore, having must
Design a kind of soft boots pressure device suitable for toilet paper machine production.
