Description
Technical field
The utility model is related to papermaking equipment fields, and in particular to a kind of page transfer roller arrangement.
Background technology
Paper technology is roughly divided into two steps：Paper pulp molding and page moisture removal.In forming part, paper pulp molding is formed
The higher page of water content, is then transferred to press section by transfer device, by press section to remove excessive moisture in page,
Finished product page is set to reach qualified degree of draining.
In the prior art, page is shifted by transferring roller from forming part to press section, in transfer process, due to driving page
The roller of transfer is oppositely arranged up and down so that page enters press section pressure area with horizontal direction, this causes air to be easy with paper
Page enters roll nip and press section pressure area, and then bubbling is generated under page, will finally page be caused to give a discount.Especially producing
When lightweight paper page, large quantity of air is easier to bring press section pressure area by page, and page bubbling will continue to increase, and pass through in page
During press section pressure area, large quantity of air causes page both sides to wrinkle when being flowed to both sides among page, occurs more serious
Discounting phenomenon.Page, which gives a discount, will lead to the serious consequence of sheet break.
Chinese patent CN206873195U provides a kind of suction roller of fast dewatering to avoid page discounting problem, wraps
It includes and aspirates roller body, drip tray, scraper, the first felt, wet end and the second felt, suction roller is in contact with the first felt；Water receiving
Disk closely install by suction roller direction of rotation, and the side close to suction roller in drip tray is arranged in scraper, with drip tray side at 90~
150°；Horizontal plane residing for scraper is located at below the horizontal plane aspirated residing for roll axis；It includes roller bearing and setting to aspirate roller body
Roll body is aspirated on roller bearing, protective layer is coated with outside suction roller body, it includes suction roller body wall, suction roller body wall to aspirate roll body
Be arranged on protective layer it is several aspirate hole, prevent the anti-reverse of moisture adverse current close to aspirating hole site and be provided on the inside of suction roller body wall
Flow device；Second felt is set to wet end.The suction roller of the fast dewatering, the mass dryness fraction for the paper for ensureing out reduce follow-up steam
Consumption meets the needs of environmental protection and client to produce the product for capableing of fast dewatering.But which increase the energy of equipment
Consumption, and maintenance cost also increases simultaneously.
Meanwhile in page transfer process, there is also the risks come back on page for the moisture on felt.Water on felt
Divide and come back on page the water content that will increase page, is lowered into the degree of draining of press section page, it is up-to-standard to obtain
Finished product page, paper machine will be by further increasing press section equipment energy consumption.
Accordingly, it is desirable to provide one kind effectively can avoid page from giving a discount, while moisture on felt being avoided to come back to page
The lower page of upper and energy consumption shifts roller arrangement.
Utility model content
