Abstract
The utility model relates to a paper wrinkle-resistance guide roll, which can effectively prevent papers from wrinkling, and has the advantages of simple structure and convenient use. The paper wrinkle-resistance guide roll comprises a guide roll body, and is characterized in that the two spiral expansion line slots are arranged on the circular surface of the guide roll body, the two spiral expansion line slots are respectively spirally expanded to the two end portions from the middle position of the guide roll body, and the spiral directions of the two spiral expansion line slots are opposite.
Description
Technical field
The utility model relates to printing machinery technical field, specifically the guiding roller of intaglio press.
Background technology
In intaglio press, walking material system starts to extend to winding portion from the portion of unreeling and finishes, in this system, main part is exactly guiding roller, so guiding roller be in intaglio press quantity at most, one of the widest, the part that has the greatest impact of distributing, the vital function that mainly plays traction, flattening paper and compensation, transferring power, the service condition of guiding roller directly has influence on the normal operation of paper printing quality and even whole printing equipment.Guiding roller adopts aluminium alloy extrusions to process conventionally, on its surface, can hold system intersection wire casing (is bidirectional screw wire casing, as shown in Figure 2), these wire casings can play the effect of getting rid of residual air between paper and guiding roller on the one hand, can increase on the other hand the friction force to paper, prevent from skidding; The guiding roller of similar this kind of structure requires paper very high with the parallelism of guiding roller axis, once have local wrinklingly in operational process, after multiple guiding rollers amplify, there will be wadding in a big way, normally the carrying out and the quality of paper of impact production.
Utility model content
The purpose of this utility model is the deficiency overcoming in above-mentioned background technology, and a kind of anti-wadding guiding roller is provided, and this guiding roller should be able to prevent curl effectively, and has feature simple in structure, easy to use.
For realizing above object, the utility model has adopted following technical scheme:
A kind of anti-wadding guiding roller, comprise a guiding roller body, it is characterized in that: the circumferential surface of described guiding roller body offers two sections of spirals and launches wire casing, two sections of described spirals launch wire casing and by the position, middle of guiding roller body, to two end convolution, are launched respectively, and the hand of spiral of two sections of spiral expansion wire casings is contrary.
The external diameter of described guiding roller body reduces gradually from two position, Xiang Qi middle, end, forms two and is arranged symmetrically with and round table surface that upper bottom surface is connected, and described guiding roller body is less than the external diameter 0.03-0.08mm of end at the external diameter of position, middle.
The helical angle that described spiral launches wire casing is 45～60 degree, and helical pitch is 6-10cm, groove width 3-5mm, groove depth 1.5～2.0mm.
Principle of work of the present utility model is:
1. after opening two sections of spirals expansion wire casings of system, on the surface of guiding roller body, form two pulling faces that stretch to two ends spiral from position, middle respectively, in the process of guiding roller rotation, pulling face can apply to paper the component of both direction, component is perpendicular to the axis of guiding roller body, the power advancing as paper, another component is parallel to the axis of guiding roller body the edge application of force towards paper width direction, this power can flatten paper to a certain extent, improves the situation of wadding;
2. the external diameter of guiding roller body reduces gradually from two position, Xiang Qi middle, end, at guiding roller body cireular frequency is identical everywhere in the situation that, the position linear velocity that radius is larger is higher, therefore the linear velocity of guiding roller body surface increases to end gradually from its position, middle, paper can be oriented the trend of two ends motion (because deflector roll is symmetrical, so these two movement tendencies can be cancelled out each other under normal circumstances), when having part to occur wadding, wrinkling position can be towards deflector roll two end motions, shakeout, thereby effectively solve wadding problem.
The beneficial effects of the utility model are: the utility model launches wire casing and reduces the radius at deflector roll middle part by offering spiral; deflector roll can be shakeout wrinkling position (in actual production when rotating; when curl is serious; through several deflector rolls, can realize and shakeouing); even paper and deflector roll slightly error of parallelism; also can shakeout voluntarily; without shutting down, safeguard; guarantee the quality of paper; and integral structure is simple; realize easily, installation process is identical with existing deflector roll, can not increase overwork amount.
Accompanying drawing explanation
Fig. 1 is main TV structure schematic diagram of the present utility model.
Fig. 2 is the main TV structure schematic diagram of existing guiding roller.
The specific embodiment
Below in conjunction with Figure of description, the utility model is described in further detail, but the utility model is not limited to following examples.
As shown in Figure 1, a kind of anti-wadding guiding roller, the guiding roller body 1(that comprises an aluminum is equipped with rotating shaft 3), the circumferential surface of described guiding roller body offers two sections of spirals and launches wire casing 2, two sections of described spirals launch wire casing and by position, the middle A of guiding roller body, to two end B spirals, are launched respectively, the helixangleβ that spiral launches wire casing is 45～60 degree, helical pitch S is 6～10cm, groove width 3～5mm, groove depth 1.5～2.0mm, and two sections of spirals launch the hand of spiral contrary (cw, another conter clockwise) of wire casing.
The external diameter of described guiding roller body reduces to its position, middle A gradually from two end B, forms two and is arranged symmetrically with and round table surface that upper bottom surface is connected, and described guiding roller body is less than the external diameter 0.03-0.08mm of end at the external diameter of position, middle.
In Fig. 2, also has intersection wire casing 4.
