Abstract
The utility model discloses a novel roll paper crimp-preventing device which consists of a paper guiding roller (1), a reverse rotation roller (2), a wall board (3), a locking screw (4) and a bearing seat (5). The paper guiding roller (1) is fixed on the wall board (3) through the locking screw (4), the reverse rotation roller (2) is located under the paper guiding roller (1) slantingly and connected with the bearing seat (5), and the bearing seat (5) is fixed on the wall board (3). The novel roll paper crimp-preventing device has the advantages of being scientific in design, simple in structure, convenient to install, quick to maintain and good in crimp-preventing effect, improving the product pass percent and the like, widely meets the paper crimp-preventing operation requirement in the printing industry and is an effective helper in the domestic printing industry and worthy of popularization.
Description
Technical field
The utility model relates to field of printing machinery, is exactly a kind of web paper Anti-curling device specifically.
Background technology
In China's print field, cigarette peduncle paper printing occupies more than half market at present.Generally, processing after thin paper printing is applicable to circle and presses circle guillotine, paper in reel circle is pressed circle guillotine, and generally by unreeling,---------six master operations such as secondary traction---cross cutting---finished product collection are formed, and ground paper is applicable to paper transverse cutting unit in one-level traction in correction.Yet, in production practice, because being subject to the impact of the factors such as printing process and raw MAT'L, no matter be thin paper or ground paper, all there is the phenomenon that paper is curling, particularly evident with the slim paper of 100 grams/m of following specifications.If paper upsweeps, generally adopt the method for humidification to improve, but effect is still undesirable; If paper is curling downwards, under prior art condition, cannot solve.Paper curling, affects the exterior quality of product, causes reject rate to rise, and client's product applicability is affected greatly simultaneously.Therefore, be necessary it to be further improved.
Summary of the invention
The utility model just can effectively overcome above-mentioned technical disadvantages, provide there is design science, simple in structure, easy for installation, maintenance is quick, Anti-curling is effective, improve a kind of web paper Anti-curling device of the features such as conforming product rate, it is widely used in the job requirements of printing industry to paper Anti-curling, be the capable helper of domestic press, be worth promoting.
Technical purpose of the present utility model is achieved in that a kind of web paper Anti-curling device, dancing roll, reverse roll, wallboard, tie down screw, bearing seat, is consisted of.Dancing roll is fixed on wallboard by tie down screw, and reverse roll is positioned at the oblique below of dancing roll, and reverse roll is connected with bearing seat, and bearing seat is fixed on wallboard.
Described dancing roll carries bearing, and is hollow structure;
Described dancing roll and the quantitative proportion of reverse roll are N:(N-1);
Described dancing roll, the quantity of reverse roll, can increase and decrease according to actual effect, generally take 4 dancing rolls, 3 reverse roll proportionings as best;
The installation parallel with reverse roll of described dancing roll, and can rotate with paper;
First described reverse roll is positioned at the back lower place of first dancing roll, and first reverse roll is positioned at the back upper place of second dancing roll, the roll surface spacing of dancing roll and reverse roll between 15-30 millimeter, after by that analogy;
Described a kind of web paper Anti-curling device, a dancing roll is furnished with two tie down screws, and a reverse roll is furnished with two bearing seats;
Principle of work of the present utility model is: by the effect of dancing roll and reverse roll, change the running orbit of paper, and under the tension force effect of equipment, make paper high and low, again and again bend motion, thereby become smooth, make it enter smoothly subsequent processing, reach and eliminate the curling object of paper.
The beneficial effects of the utility model are:
1, prevent that rolled efficiency is good.Conventional roll coil paper printing technology is all after paper in reel is unreeled, rectified a deviation, directly to enter printing machinery to carry out production operation, paper in reel, particularly slim paper, easily occur curling up or down, if paper upsweeps, traditional method is humidification, but effect is still undesirable; If curling downwards, under prior art, cannot solve.The utility model device, is exactly to be used for specially preventing that paper is curling, by the effect of dancing roll and reverse roll, changes the running orbit of paper, and under the tension force effect of equipment, makes paper high and low, again and again bends motion, thereby become smooth.
2, improve conforming product rate.In existing printing technology, this device is not installed, when production operation, can often there is the curling phenomenon of paper, make unstable product quality, reject rate rises.This product is arranged on the paper transport path before printing machinery paper feed, paper is before entering printing machinery production, must, through the operation of this device Anti-curling, guarantee that paper can entirely enter the subsequent handlings such as traction, cross cutting, thereby improve the qualification rate of product.
3, easy to maintenance quick.The utility model product structure is simple, parts convenient disassembly and with low cost, more easily maintenance after breaking down.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is made to more full and accurate explanation
Fig. 1 is structural representation of the present utility model and doubles as Figure of abstract
In figure: 1, dancing roll, 2, reverse roll, 3, wallboard, 4, tie down screw, 5, bearing seat
The specific embodiment
By the following examples, the utility model is described in more detail, but as long as within the scope of main idea of the present utility model, is not limited in following examples.
A web paper Anti-curling device, is comprised of dancing roll (1), reverse roll (2), wallboard (3), tie down screw (4), bearing seat (5).Dancing roll (1) is fixed on wallboard (3) by tie down screw (4), reverse roll (2) is positioned at the oblique below of dancing roll (1), reverse roll (2) is connected with bearing seat (5), and bearing seat (5) is fixed on wallboard (3).
It is example that the present embodiment only be take four dancing rolls, three reverse roll proportionings:
During work: paper in reel from top to bottom first through the upper surface of first dancing roll (1) around to lower surface, again through the upper surface of first reverse roll (2) around to lower surface, again through the upper surface of second dancing roll (1) around to lower surface, same principle, until through the upper surface of the 4th dancing roll (1), then entering circle, paper in reel press circle guillotine or paper transverse cutting unit to be produced into finished product or half-blank.
Above-described embodiment is only one of preferred embodiment of the present utility model; not with this, limit protection domain of the present utility model; therefore: all equivalences of doing according to shape of the present utility model, structure, principle change, within all should being covered by protection domain of the present utility model.
