The structure of the invention is as follows: in the rubberizing arrangement of the tier calendering working procedure in which it uses the auxiliary compression roller (2) and the compression roller (3) to do number arraying to the steel wire (1) provided by the expending machine and simultaneously provides the steel wire to the calendering host machine roller (4) to do rubberizing (5), the auxiliary compression roller (2) is arranged with the state that it is separated from the compression roller (3), the degree between the connecting line that starts from the center of the compression roller (2) to the center of the compression roller (3) and the horizontal line (L) is between 10 degrees to 30 degrees (theta), the depth (H) of the containing groove (6) of the compression roller (3) to accommodate the steel wire (1) is arranged to be 45 percent to 55 percent of the diameter (D) of the steel wire (1).
Description
Technical field
The present invention relates to a kind of roller structure, when in the calendering procedure of making tire, producing belt or carcass with steel wire rubberizing sheet, be used for arranging EPI (Ends perinch cord density) as the steel wire radical, relate in particular to the cohesive force and the rubber permeability that can improve steel wire and rubberizing, when reducing cord cohesive force bad, the wire radical that can obtain the tire calendering procedure of uniform rubberizing EPI is arranged the roller structure of usefulness.
Background technology
As everyone knows, so-called tire calendering procedure is meant on the two sides of unprocessed cord steel wire is set, and covers the operation of certain thickness rubber then, also can be called rubberizing (Topping) operation.
That is to say, in existing tire calendering procedure, when steel wire is carried out rubberizing, for the EPI that arranges with the radical of this steel wire is harmonious, by help roll and pressure roller the radical of described steel wire is allocated, all-steel cord is placed on the calender main frame roller, then, carry out rubberizing.
In addition, in calendering procedure,, then can cause the bad of cord if the cord mounting groove degree of depth of described pressure roller is too shallow; On the contrary, if the degree of depth of this mounting groove is too dark, produce adverse influence when then on calender main frame roller, being placed to cord on the rubber.
Yet, prior art as above is described, because the structure of the structure of described pressure roller and all-steel cord, gauge of wire and cord (for example, mutually the amount of twining, whether solderless wrapped connection (Wrapping) is arranged), have more difficulty aspect the depth structure of setting the pressure roller groove.
Summary of the invention
The present invention proposes in order to solve described the problems of the prior art, its purpose is to provide a kind of steel wire radical of the tire calendering procedure that has improved to arrange the roller structure of usefulness, when steel wire is carried out the rubberizing operation, can improve the cohesive force and the rubber permeability of steel wire and rubberizing, it is half-finished bad to reduce tire.
To achieve these goals, structure of the present invention is, carry out in the tape sticking device of tire calendering procedure of rubberizing by auxiliary pressure roller and pressure roller the steel wire that is provided by the expansion machine being carried out when radical is arranged its steel wire being offered calendering main frame roller, the state setting of described auxiliary pressure roller to separate with pressure roller, should assist the center of pressure roller to become 10 °～30 ° angles with horizontal line with the line at the center of pressure roller, the degree of depth of the steel wire mounting groove of described pressure roller is arranged to 45%～55% of described steel wire diameter.

Shown in Fig. 4 (B), (C) be according to the present invention and existing apparatus permeates the comparison diagram of the degree of rubber between steel wire.
The specific embodiment
Below, the present invention is described in detail with reference to the accompanying drawings.
Shown in Figure 1 is is arranged on state brief configuration figure in the tire calendering procedure with the present invention, Fig. 2 and shown in Figure 3 be the front view and the part amplification profile of major part of the present invention.
Of the present invention being constructed as follows: carry out in the tape sticking device of tire calendering procedure of rubberizing 5 carrying out when radical is arranged its steel wire being offered calendering main frame roller 4 by auxiliary pressure roller 2 and 3 pairs of steel wires that provide by the expansion machine 1 of pressure roller, the state setting of described auxiliary pressure roller 2 to separate with pressure roller 3, should assist the center of pressure roller 2 to become 10 °～30 ° angles (θ) with horizontal line L with the line at the center of pressure roller 3, the depth H of steel wire 1 mounting groove 6 of described pressure roller 3 is arranged to 45%～55% of described steel wire 1 diameter D.
That is to say that the present invention carries out radical by auxiliary pressure roller 2 and 3 pairs of steel wires 1 that provided by known expansion machine of pressure roller and arranges, wherein the depth H of the mounting groove 6 of described pressure roller 3 is carried out calibration setup one time in 45%～55% the mode of steel wire 1 diameter D.
In addition, Height Adjustment as described pressure roller 3 and auxiliary pressure roller 2, that is to say, the state setting of described auxiliary pressure roller 2 to separate with pressure roller 3, center that should auxiliary pressure roller 2 and the line at the center of pressure roller 3 become the structure of 10 °～30 ° angles (θ) with horizontal line L, arrangement radical to steel wire 1 carries out the secondary correction, when carrying out rubberizing with 4 pairs of steel wires 1 of described calendering main frame roller and rubber, can improve cohesive force and rubber permeability.
On the other hand, the comparison sheet of the cohesion test of the present invention and cord existing apparatus, steel cord rolled products and rubber is used in following table 1 expression, hence one can see that, the permeability of the sample that obtains by the present invention is than the calendering rubberizing sheet that obtains by existing apparatus, and its rubber permeability is very much better.
