Abstract
The papermaking film all-in-one that this technology provides a kind of economize energy, reduces body paper waste, improves working (machining) efficiency.It comprises dewatering of pulp device, pressing device, drying unit, calendering device, wrap-up, between calendering device and wrap-up, arrange film device, it is silica gel roller, squeeze film head, the screw extruder of silica gel that described film device comprises chill roll and surface in relative rotation; Through squeezing synthesis body paper after dewatering of pulp, dry, then pass through between chill roll and silica gel roller after press polish, then rolling; Have the squeeze film head for polyethylene being extruded between chill roll and body paper above between chill roll and silica gel roller, squeeze film head communicates with providing poly screw extruder to it.
Description
Technical field
This technology relates to paper making equipment, specifically, is papermaking film all-in-one.
Background technology
Paper making equipment generally comprises dewatering of pulp device, pressing device, drying unit, calendering device, wrap-up; Paper manufacturing streams generally, through squeezing synthesis body paper after dewatering of pulp, then drying, rolling after press polish.
In order to body paper film, need the body paper that width is very wide to be cut into the less small-sized body paper of multireel width, then by have unwinding device, film device, wrap-up film equipment film is carried out to the small-sized body paper of each volume.
When papermaking, need wrap-up to body paper rolling, when body paper is cut into small-sized body paper, also need small-sized body paper unwinding and rewinding; When film, also need small-sized body paper unwinding and rewinding.That is, in order to body paper film, need repeatedly unwinding and rewinding, waste manpower and materials, production efficiency is low.And, when carrying out film, due to two edges often rolling up small-sized body paper have cannot the slitter edge of film, and for the small-sized body paper of multireel, slitter edge just has 2n, and n is the volume number of small-sized body paper.This also result in the waste of body paper.
Summary of the invention
The object of this technology is to provide the papermaking film all-in-one of a kind of economize energy, the waste of minimizing body paper, raising working (machining) efficiency.
Papermaking film all-in-one described in this technology, comprise dewatering of pulp device, pressing device, drying unit, calendering device, wrap-up, between calendering device and wrap-up, arrange film device, it is silica gel roller, squeeze film head, the screw extruder of silica gel that described film device comprises chill roll and surface in relative rotation; Through squeezing synthesis body paper after dewatering of pulp, dry, then pass through between chill roll and silica gel roller after press polish, then rolling; Have the squeeze film head for polyethylene being extruded between chill roll and body paper above between chill roll and silica gel roller, squeeze film head communicates with providing poly screw extruder to it.
In order to fully cool silica gel roller, above-mentioned papermaking film all-in-one, described film device also comprises and silica gel roller the second chill roll in relative rotation, and described chill roll and the second chill roll lay respectively at the both sides of silica gel roller.
Above-mentioned papermaking film all-in-one, is characterized in that: all have axial cooling duct in chill roll, silica gel roller, the second chill roll, cooling water flow supercooling passage.By cooling water, chill roll, silica gel roller, the second chill roll are cooled, cool rapider.
The beneficial effect of this technology: this technology is organically combined papermaking with film, film is carried out in paper-making process, specifically,, after body paper press polish, before rolling, polyethylene is applied to body paper, and by the extruding of chill roll and silica gel roller, make polyethylene be coated in a side surface of body paper uniformly.In addition, we know, from about 150 DEG C of the polyethylene that squeeze film head is extruded, temperature is higher, and chill roll also plays cooling effect to polyethylene and silica gel roller.This technology carries out film to body paper, carries out film again, decrease operation, energy efficient without the need to being cut into the small-sized body paper of multireel to body paper; And after film, only have two slitter edges, save body paper.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of papermaking film all-in-one.
Detailed description of the invention
See the all-in-one of papermaking film shown in 1 shown in figure, comprise dewatering of pulp device, pressing device, drying unit, calendering device 1, film device 2, wrap-up 3.Film device is between calendering device and wrap-up, and described film device comprises chill roll 4, second chill roll 5 and surperficial silica gel roller 6, squeeze film head 7, screw extruder for silica gel.Chill roll and the second chill roll lay respectively at the both sides of silica gel roller, and silica gel roller is drive roll, drive the chill roll and the rotation of the second chill roll that are in contact with it.The cooling duct 8 that axial Cooling Water flows through all is had in chill roll, silica gel roller, the second chill roll.Through squeezing synthesis body paper 9 after dewatering of pulp, then drying, to pass through between chill roll and silica gel roller after two pressure roller press polish of calendering device again, the wind-up roll winding then in wrap-up.Squeeze film head communicates with providing poly screw extruder to it, for polyethylene is extruded into squeeze film head between chill roll and body paper between chill roll and silica gel roller above.Screw extruder delivers to squeeze film head the polyethylene of melting, and is expressed between chill roll and body paper by squeeze film head, by the extruding of chill roll, makes polyethylene coating on body paper surface.The width of polyethylene on silica gel roller axial direction squeezed out from squeeze film head is slightly less than the width of body paper, and the polyethylene width that body paper width equals to squeeze out from squeeze film head substantially adds the width of two of body paper both sides uncoated polyethylene slitter edges.
Claims (3)
1. papermaking film all-in-one, comprise dewatering of pulp device, pressing device, drying unit, calendering device, wrap-up, it is characterized in that: between calendering device and wrap-up, arrange film device, it is silica gel roller, squeeze film head, the screw extruder of silica gel that described film device comprises chill roll and surface in relative rotation; Through squeezing synthesis body paper after dewatering of pulp, dry, then pass through between chill roll and silica gel roller after press polish, then rolling; Have the squeeze film head for polyethylene being extruded between chill roll and body paper above between chill roll and silica gel roller, squeeze film head communicates with providing poly screw extruder to it.
