Description
Technical field
The present invention relates to the technical field of paper making equipment, specifically a kind of high speed paper machine, more particularly to its machinery
Attachment structure.
Background technology
Documents, the patent No.：200980136442.6 the applying date：2009.09.16 patentee：Metso is worn
Amber karr Si Tade companies, this case disclose a kind of " tissue machine and the method for manufacturing tissue paper web ", the thin paper papermaking
Machine includes：For forming the wet end of fibrous web；For squeezing the press section of the fibrous web, the press section includes：It is single
Individual squeezer, the squeezer include：First pressing part；Second pressing part, formed between the pressing part have it is pre-
The press. nips of constant-pressure；Press felt, the press felt around multiple deflector rolls and with the fibrous web one of formation
Rise by the press. nips and contacted with the fibrous web to be run with loop checking installation, second pressing part is arranged on institute
State the inner side in the loop of press felt；Smooth zone, the smooth zone around multiple deflector rolls and with the fibrous web one of formation
Rise by the press. nips and contacted with the fibrous web to be run with loop checking installation, first pressing part is arranged on institute
State the inner side in the loop of band；And transfer roller, the transfer roller are arranged on the inner side in the loop of the smooth zone；Drying section, this is dry
Dry portion is used to finally dry the fibrous web after squeezing in the press. nips, and the drying section includes being used for institute
State the fibrous web after squeezing and carry out finally dry drying surface；The transfer roller is arranged to together with the dry surface
Transmission nip is formed, for the fibrous web to be sent into the dry surface, wherein the smooth zone is arranged in institute
State and transport the fibrous web after the squeezing between press. nips and the transmission nip, the tissue machine is characterised by：
The upstream of the squeezer is provided with pre-dehydration device, to run the pressure for entering the squeezer in the fibrous web
Area is squeezed before by the fibrous web predrainage to preferably 15-30% mass dryness fraction；And the press felt and the light
Slide strips are arranged to after the press. nips are left separate and define therebetween that angle α, angle α are at least 5 ° each other immediately
To prevent the fibrous web rewetting after the squeezing.
From the foregoing, it can be understood that during the head box operation of existing general paper machine, its intensity in length and breadth to page is to carry out
Adjustment, intensity requirement of the various occasions in market to finished paper can not be met.Paper machine is in the process of running if hair simultaneously
Excessive wear, which occurs, in blanket just to be needed to change in time, because woollen blanket is pressed on rod lower side, it is necessary to one ton of the rod of weighing of driving a vehicle
Son lifting rear is replaceable, and whole process wastes time and energy, and have impact on the production efficiency of paper machine.
Due to paper machine in paper process is processed, it is necessary to page is dried, when paper industry is dried, a large amount of water can be produced and steamed
Gas.Because page and yankee cylinder are initially contacted to leaving, the degree of saturation of its water vapour is different.During initial contact, its water steams
Vapour contains saturated vapor, very moist, it is impossible to which reuse, then the steam quality in stage is higher, can reclaim substantially.It is and existing
The humidity discharging moist steam device of paper machine is generally too complicated, and complete equipment cost is high, maintenance inconvenience, or only installs one
Simple equipment, humid air is discharged, and is not handled differently for the steam in former and later two stages, is wasted substantial amounts of dry
Dry steam, is unfavorable for energy-saving and emission-reduction.Finally, high-speed broad-width toilet paper goes out yankee cylinder, need to be performed with creping doctor.A period of time makes
After, blade is all over the blunt blade for needing more to renew.Because blade is wider, it is necessary to which 2 people, which operate, could complete tool changing simultaneously
Work, entirely extracts old knife out, and inserting the process of new knife needs to take one minute or so, for high-speed paper machine, fortune per second
Rotary speed will reach 20 ms/min, shut down the time of one minute, and the paper yield of a km will be lost.
The content of the invention
It is an object of the invention to provide a kind of improved paper machine, and it can overcome the head box of paper machine in the prior art
Intensity in length and breadth to page is to be adjusted, and the woollen blanket of paper machine is not easy to change, the drying section of paper machine is to dry steam
Not recycle, while paper machine scraper is replaced and is not easy, some shortcomings to waste time and energy.
To achieve these goals, the technical scheme is that：A kind of high speed paper machine, it mainly include pedestal and according to
The secondary forming part being arranged on pedestal, press section, drying section and corrugation portion, it is characterised in that：Forming part is provided with paper forming machine
Structure and head box adjustment mechanism, press section are provided with paper dewatering mechanism and roller hoisting mechanism, and drying section is provided with humidity discharging moist steam
Device, corrugation portion are provided with doctor assemblies and paper winder.
In use, paper pulp is sprayed by head box, l Water Paper page is formed between the forming net and woollen blanket above format roll, is led to
The effect of overmolding roller centrifugal force is dehydrated, and the page after dehydration is run between vacuum carrying roller and yankee cylinder with woollen blanket,
Further carry out high line super pressure-high temperature dehydration.Page is peeled off, and then run by the creping doctor in yankee cylinder from yankee cylinder
Coil paper is carried out to reel machine, so as to complete from paper pulp to the process into paper.
Due to being provided with head box adjustment mechanism in forming part, by the regulation of head box spray angle, control slurry falls
A slurry point position, so as to be implemented as the requirement of paper different tension intensity performances in length and breadth.Press section is provided with roller hoisting mechanism, when need
Will more felt changing when, rotating nuts, roller is just elevated, and after reserving space, woollen blanket is just easily exchanged.Whole mechanism operation letter
Just, it is more efficient, multiple rollers can be lifted simultaneously, do not limited by driving a vehicle.Drying section is provided with humidity discharging moist steam device,
Water vapour very moist caused by page and yankee cylinder initial contact can be separated with gas hood, then pass through gland steam exhauster
Emit, when page advances to the rear stage, the steam quality in gas hood is higher, can directly recycle, this with simple
The structure method that is handled differently water vapour it is highly effective, be greatly improved energy-saving effect, and apparatus structure is simple, cost
It is relatively low, for ease of maintenaince and maintain.Corrugation portion is then provided with tool changing sheet devices, and whole exchanging knives process only needs one man operation complete
Into, while tool change time is original a quarter, substantially increases the efficiency of allowing blade replacement, reduces labor intensity, improves
Production efficiency.
