Abstract
The utility model discloses a paper web surface flattening processing apparatus, including setting up the upper and lower felt wrapped roll on the paper machine, be close to the overarm brace lower part of going up felt wrapped roll paper feed front end vertically is equipped with the heating device corresponding with the paper web width, and heating device includes that the under shed longitudinal section is the mounting groove and a plurality of heating unit of setting in the mounting groove of establishing ties of U -shaped, and vertical size of mounting groove is unanimous with the width size of paper web, the heating surface of every heating unit corresponds corresponding region in the width of paper web respectively, and a plurality of heating unit covers the whole region that heating mounting groove and paper web width correspond jointly. The utility model discloses a set up heating device and heat the paper web that gets into before the felt wrapped roll, make the paper web ascending plastic deformation in thickness side will only be limited to the region that paper surface temperature reaches and is higher than the fluxing point, and will only produce elastic deformation in the inside thickness orientation of paper web to improve the level and smooth degree and the glossiness of paper web, make the paper web keep the purpose of higher bulk.
Description
Technical field
The utility model belongs to pulp technology for making paper, specifically, relates to a kind of paper surface leveling treating apparatus.
Background technology
In paper, because of the impact of factors such as paper pulp online evenness, wire mark and blanket marks etc., all there is surface irregularity, smoothness is low and glossiness is low phenomenon in Paper or cardboard.Prior art utilizes hard calender or soft press-polishing machine to modify paper surface.Hard calender adopts the principle of mechanical presses paper surface to be flattened to improve its planarization, but the raising still Shortcomings to paper surface smoothness and glossiness; Soft press-polishing machine is that admittance deep fat or steam improve roll surface temperature to felt wrapped roll heating in felt wrapped roll roll body, when paper web enters felt wrapped roll nip, hot pressing is carried out to paper surface, improve smoothness and the glossiness of paper surface, but conduction oil or steam are easily from felt wrapped roll side leakage, thus produce pollution to paper surface, and corollary equipment is complicated, use cost is high.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, by adopting trimming device to solve problems of the prior art, thus provides a kind of paper surface to flatten treating apparatus.
In order to realize the purpose of this utility model, the technical solution adopted in the utility model is:
A kind of paper surface leveling treating apparatus, comprise that to be arranged on paper machine upper, lower felt wrapped roll, longitudinally the heater corresponding with paper web fabric width is provided with near the overarm brace bottom of described upper felt wrapped roll paper feed front end, heater comprises mounting groove that under shed longitudinal section takes the shape of the letter U and is arranged in series several heating units in mounting groove, the longitudinal size of mounting groove and the fabric width consistent size of paper web, respective regions in the fabric width of the corresponding paper web of heating surface difference of described each heating unit, several heating units cover the heating mounting groove whole region corresponding with paper web fabric width jointly.
Described U-lag groove inwall is provided with reflecting layer.
Described heating unit is electrothermal tube.
The utility model heats entering the paper web before felt wrapped roll by arranging heater, plastic deformation on web thickness direction to be reached being only limitted to paper surface temperature and higher than the region of fluxing point, and paper web inner thickness direction only will produce elastic deformation, thus the bulk of paper can remain on higher level after making press polish process, reach the smoothness and glossiness that not only improve paper web but also paper web can be made to keep the object of higher bulk.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Fig. 2 is the structural representation of the utility model heater;
In figure: upper and lower felt wrapped roll 1,2, paper web 3, heater 4, overarm brace 5, mounting groove 6, heating unit 7.
Detailed description of the invention
The utility model specifically can be implemented by the technology illustrated in technical scheme, and by the following examples can the utility model will be further described, but scope of the present utility model is not limited to following embodiment.
Embodiment: as Fig. 1---shown in Fig. 2;
A kind of paper surface leveling treating apparatus, comprise that to be arranged on paper machine upper, lower felt wrapped roll 1, 2, longitudinally the heater 4 corresponding with paper web 3 fabric width is provided with near overarm brace 5 bottom of described upper felt wrapped roll 1 paper feed front end, heater 4 comprises mounting groove 6 that under shed longitudinal section takes the shape of the letter U and is arranged in series several heating units 7 in mounting groove 6, the longitudinal size of mounting groove 6 and the fabric width consistent size of paper web 3, respective regions (namely each heating unit controls the heating in certain fabric width region) in the fabric width of the corresponding paper web 3 of heating surface difference of described each heating unit 7, several heating units 7 cover the heating mounting groove 6 whole region corresponding with paper web 3 fabric width jointly.
Described U-lag 6 groove inwall is provided with reflecting layer, and reflecting layer can adopt, and as pasted aluminium foil, or adopting the mode of mirror process to be formed, can improve the thermal efficiency by arranging reflecting layer.
Heating unit 7 generally adopts electric energy as thermal source as the control device of large power, electrically heat pipe heater 4 accesses QCS/DCS system or outside connected switch by Artificial Control by overarm brace 5.
When the paper web that paper machine runs by upper and lower felt wrapped roll 1,2 time, heater is energized, heating unit 7 is heated and is heated by paper web 3 surface longitudinal of heat radiation to respective regions, improving the temperature on paper web 3 surface makes paper web 3 surface fiber temperature reach or higher than fluxing point, during the nip that paper web is passed through subsequently, plastic deformation on the paper sheet thickness direction that felt wrapped roll produces page extruding is only limited to paper surface temperature and reaches or higher than the region of fluxing point, and paper inner thickness direction only produces elastic deformation.Reach the smoothness and glossiness that not only improve paper but also paper can be made to keep the object of higher bulk.
