Description
Technical field
The invention belongs to the technical field of paper for daily use papermaking, specially a kind of control method of shaping part device.
Background technology
Paper for daily use is quantitatively relatively low, typically in 10-30g/m2, Substance is lower, the evenness of paper is required higher.?
Paper for daily use field of papermaking, Fourdrinier yankee machine are most widely used types, during paper for daily use of manufacturing paper with pulp, general logical
Overregulate the jet nit point of slurry to improve the evenness of paper.Pulp suspension is through head box with certain spray angle and jet velocity
Degree injection is to being coated on the bag net and forming net of breast roll.The position of pulp suspension injection is referred to as jet nit point, and jet nit point is to length
For net paper machine, it is an extremely important parameter, it determines original shaping, so as to affect paper formation and retention, paper
Various physical properties have much relations with evenness, and evenness is bad, not only affect the physical property of paper, and also impact paper is outer
See, finally affect into the use quality of paper.Application No.：201310080979.3《The method for improving pulp fiber intertexture effect》
Chinese invention patent provide a kind of method for improving pulp fiber intertexture effect, the method uses fourdrinier machine, the length
Net paper machine includes to house the head case of slurry, the breast roll that neighbouring head case is arranged and net for no reason, this for no reason net include forming net and
The bag net being coated on breast roll, the head case are provided with a mouth spray to spray pulp suspension, the whitewashing to bag net and forming net
Mouth is made up of top lip of slice setting up and down and aulaeum, and the breast roll is located at below aulaeum, and the position of pulp suspension injection claims
For jet nit point, on the breast roll, the centreline definition of vertical forming net initiating terminal is vertical center line, and the method is by adjust net
The vertical center line that the starting point of point is located at horizontal range breast roll is online for the bag of 8-12mm, vertical interval between aulaeum and breast roll
For 3.7-3.8mm, the purpose of the intertexture effect for improving pulp fiber is reached.The present invention is online in the bag of breast roll by reducing page
Original shaping, be effectively improved slurry intertexture effect of the pulp suspension in jet nit point, lift paper product quality.But this regulation
Mode is very single, can not improve sometimes the evenness of paper only by adjustment jet nit point well.
Shake machine is important equipment in the paper machine, by the shake to online slurry so that fiber is uniformly distributed simultaneously
Strengthen the orientation of transverse fiber, hence for becoming the evenness of paper, aspect intensity ratio, become paper surface quality etc. to have significantly
Optimization function.Traditional shake machine application when, paper machine highest operating speed in 300m/min, with paper machine operation speed
Raising, traditional shake machine is all increasingly unsatisfactory for use requirement on amplitude, shake frequency.As paper for daily use is quantitatively relatively low, car
Speed is higher, very high to formation of sheet requirement, generally believes shake DeGrain in current industry, and at present, papermaking producer does not still have
Have and shake machine is applied to paper for daily use manufactures paper with pulp field.
Content of the invention
Present invention aims to the problem that presently, there are and provide a kind of shaping part device control method, specifically
