Abstract
The invention discloses a roll paper on-line humidifying device which is provided with a humidifying roll arranged on a stand, a plurality of axially distributed suction passages are arranged below the roll surface of the humidifying roll, the suction passages are communicated with the outside through suction holes distributed on the roll surface of the humidifying roll; a roll paper winding section of the humidifying roll is internally provided with a water fog hood communicated with a water fog generator, an end face suction hood communicated with a vacuum pump is arranged at at least one end of the humidifying roll, and the part in which a suction mask of the end face suction hood is positioned just faces outside the suction passages below the roll surface of the humidifying roll. Compared with the prior art, the invention continuously humidifies single-layer or multi-layer paper when roll paper is unwound, and has the advantages of high humidifying efficiency and good humidifying quality.
Description
Technical field
The present invention relates to the printing machinery technical field, especially a kind of roll web that has been used for before printing to uncoiling carries out the device of humidification.
Background technology
In typography, often need print as stock two-layer or two-layer above multi-ply paper, this multi-ply paper, especially the multi-sheet printed paper that is rolled into tubular tends to take place layering, staggered floor phenomenon and causes printing product to scrap in printing process, for overcoming layering, the generation of staggered floor phenomenon, generally need on printing machine, increase a pressing mechanism, its objective is multi-ply paper is compressed, but because the low excessively influence pressurization effect that tends to of the water content of the fiber of paper and paper.The raw material of printing paper is the roll web that is rolled into tubular mostly, also such paper wood is not carried out the machinery of humidification at present, after just roll web being removed housing material mostly, place the bigger warehouse of humidity, rely on roll web to draw airborne hydrone naturally and reach the humidification purpose.This humidification process disadvantage is more, and the one, water content is wayward; The 2nd, the time is long, takes up an area of big; The 3rd, humidification is inhomogeneous, and the middle body of paper and marginal portion water content are inconsistent, even the scollop, scallop that causes edge moisture content to exaggerate generate to curl and cause whole coil paper to scrap.
Summary of the invention
Problem to be solved by this invention provides a kind of roll paper on-line humidifying device that quickly and evenly roll web is carried out humidification.
In order to address the above problem, the technical solution used in the present invention is: this roll paper on-line humidifying device has one to be contained in damper applicator roller on the frame by bearing and bearing block, the supply spool paper bag is walked around this damper applicator roller in the roll web coil feed line or in the web printing production line, the roll surface that this damper applicator roller is used for contacting with roll web has the aspirating unit of many axially-aligned, and these aspirating units are in communication with the outside by the suction hole that is distributed on the described roll surface; The water smoke cover that is communicated with water fog generator is equipped with in the outside in the position that described damper applicator roller is held by roll web, and the roll web that is used for outside surrounding described damper applicator roller provides vaporific moisture content; The end face air-suction cover that is communicated with vavuum pump is equipped with at an end or two ends at described damper applicator roller, the air entry of this end face air-suction cover covers on outside the port of the aspirating unit under that part of damper applicator roller roll surface that the cover mouth with described water smoke cover faces at least, suction by vavuum pump, make the two sides that surround the roll web on the described damper applicator roller form draught head, thereby the water smoke in the roll web outside is infiltrated roll web.
In such scheme, described aspirating unit has multiple structure according to the structure difference of described damper applicator roller, when described damper applicator roller has the part of roll surface is when being served as or being served as by a big cylindrical shell of barrel thickness by a solid cylinder, and this aspirating unit can be provided in a side of the hole in cylinder or the cylindrical shell; When described damper applicator roller has the part of roll surface is when being served as by the thin cylindrical shell of a barrel, and described aspirating unit can also be the passage that is separated to form by this cylindrical shell and the parts that are connected with this roller.
In above-mentioned each scheme, outside described damper applicator roller roll surface, along the direct of travel of roll web, be positioned at described water smoke cover rear the roll surface air-suction cover that is communicated with vavuum pump can also be housed, this cover can sop up unnecessary water smoke and be convenient to make roll web to separate with described damper applicator roller.Can also be provided with at the roll surface of described damper applicator roller and to be communicated with described suction hole, netted crossing groove, these slot openings are outside described damper applicator roller roll surface, to enlarge the air-breathing area of described suction hole to roll web, these grooves can be the grooves that groove face is " V " font according to the difference of processing technology, also can be the rectangular grooves of cross section.
Owing to adopted technique scheme, the present invention compared with prior art has following beneficial effect:
1, can be to the uncoiling process, in addition in the print production process continuously to uncoiling paper wood carry out humidification, therefore, the humidification efficiency height.
2, owing to be the paper wood two sides to be formed pressure reduction ground water smoke is infiltrated in the paper wood, therefore,, no matter be that single-part stationery or multi-ply paper can reach the purpose to the even humidification of paper wood as long as rational suction hole of abundant distribution or groove are set.
3, by the suction hole of control paper wood both sides and pressure differential and the water smoke concentration between the water smoke cover mouth, just can control the humidification degree to paper wood, therefore, can control roll web humidification degree, the humidification quality is good.

The specific embodiment
The invention will be further described below in conjunction with accompanying drawing embodiment:
The damper applicator roller of roll paper on-line humidifying device shown in Figure 1 is by being connected with left end disc left end shaft assembly 7, cylindrical shell 9, right end disc right-hand member shaft assembly 10 is by screw 8,17 connect and compose, left end disc left end shaft assembly 7 and right end disc right-hand member shaft assembly 10 all pass through bearing, bearing block 6, gripper shoe 5, base 3 and screw 2,4,14 are contained on the frame 1, right end disc right-hand member shaft assembly 10 is connected with one by key 16 and is used for and print production line locking pivoted pulley 15, the cylindrical shell 9 of damper applicator roller is to be processed into by cylinder, the hole that is drilled with 22 axially-aligned within it is as aspirating unit, these aspirating units are by the suction hole of dense distribution on cylindrical shell 9 and the external communications of cylindrical shell 9, as shown in Figure 5; Among Fig. 2, roll web on the printing production line held the cylindrical shell 9 of damper applicator roller by guide roller 21, in the roll web section of holding in the cylindrical shell outside, the water smoke cover 19 that is communicated with water fog generator 20 is housed, also be communicated with water pipe between the water tank of the lower end of water smoke cover 19 and water fog generator 20, direct of travel along roll web, the roll surface air-suction cover 18 that is communicated with vavuum pump also is equipped with in the outside that is positioned at the cylindrical shell at water smoke cover 19 rears, vavuum pump in the present embodiment is installed in other position of production line, omits among the figure to indicate.
