Abstract
The utility model belongs to a flattening roll, in particular to a soft-rubber-faced groove-type flattening roll applicable to industries about film-coating, cloth-spraying, compounding and printing and used for flattening the flexible base materials. The flattening roll comprises a central spindle which is wrapped with a soft rubber face; annular rectangular-groove are formed on the soft rubber face and distributed at intervals; and the angle of the inclined angle of each annular rectangular-groove ranges from 70 degrees to 85 degrees. The utility model has the advantages as follows: the flattening effect is good, the angle wrapping angle is wide, and the flattening roll is suitable for the expanding to a variety of flexible base materials, especially for use under the vacuum condition.
Description
Technical field
The utility model belongs to a kind of leveling roller, is specifically related to a kind of plated film that is applicable to, coating is compound, and industries such as printing flatten the flexible glue face groove leveling roller of use to flexible parent metal.
Background technology
In industries such as weaving, printing and dyeing, film, plated film, coating, compound, papermaking, printing, all exist flexible parent metal to send out the problem of wrinkle at present.Cause fold that many-sided reason is arranged.As the reason of base material itself, the reason of equipment, and many-sided influences such as technological condition and external environment condition.The defective of base material itself, in uneven thickness as base material.When base material applies tension force, in the position of the thinner thickness of base material fold appears easily.When base material when the fabric width direction has edge slack, fold also appears easily.Equipment because there is problem not parallel or distortion in each deflector roll, all causes base material fold to occur in installation and manufacturing process easily.The needs of technological condition, base material are divided in operation process between different tensile regions, also cause base material fold to occur easily.There are variation in temperature or humidity in the working environment in the technological process of whole base material, also can cause base material fold to occur.
Because above a variety of causes fold occurs for fear of base material, improves product quality and production efficiency, and all need flatten it before folding line and surface deficiency appear in base material.Multiple leveling roller has appearred in the position up till now, as the arc leveling roller, and cydariform formula leveling roller, screw-type leveling roller etc.But existing various leveling roller exists structure complicated, and the flattening effect is undesirable, shortcomings such as narrow application range.
Summary of the invention
The purpose of this invention is to provide a kind of simple in structurely, flatten effectively, the cornerite wide ranges is fit to various base materials are flattened, and is particularly useful for the flexible glue face groove leveling roller of use vacuum condition under.
The present invention is achieved in that a kind of flexible glue face groove leveling roller, and it comprises mandrel, and mandrel is surrounded by the flexible glue face outward, has the ring-type rectangular channel on described flexible glue face.
Described ring-type rectangular channel is equidistantly at the flexible glue face arranges.
The angle of the leaning angle of described ring-type rectangular channel is between 70 °～85 °.
The material of described mandrel is a corrosion-resistant steel.
The material of described flexible glue face is nitrile rubber or silaatic.
The utility model has the advantages that flatten effectively, the cornerite wide ranges is fit to various flexible parent metals are flattened, and is particularly useful for use vacuum condition under.
Description of drawings
Fig. 1 is a kind of flexible glue face groove leveling roller scheme drawing provided by the utility model.
Fig. 2 is the partial enlarged drawing of Fig. 1.
Among the figure, 1 mandrel, 2 flexible glue faces, 3 annular table, 4 circular grooves.
The specific embodiment
Below in conjunction with drawings and Examples to originally being that some information are described in detail:
As depicted in figs. 1 and 2, a kind of flexible glue face groove leveling roller, it comprises mandrel 1, mandrel is surrounded by flexible glue face 2 outward, has ring-type rectangular channel 4 on described flexible glue face 2.Described ring-type rectangular channel 4 was arranged along axially being equidistantly of flexible glue face 2.The angle of the leaning angle of described ring-type rectangular channel 4 is between 70 °～85 °.The material of described mandrel 1 is a corrosion-resistant steel.The material of described flexible glue face 2 is nitrile rubber or silaatic.
A kind of flexible glue face groove leveling roller, structure is for to process many equidistant annular rectangular channels at whole roll surface, the annular rectangular channel has certain angle of inclination, and simultaneously annular groove depth is deepened successively from leveling roller roll surface mediad two ends, simultaneously leveling roller from the centre to both sides size symmetry.Form the equally spaced ring surface that contacts with base material at roll surface.To the face institute applied pressure that goes in ring, cause the distortion of annular table by flexible parent metal tension force, the distortion of annular table is increased to both sides successively by the center, drives the flexible parent metal that is contacted and extends in the fabric width direction.Use the nitrile rubber of flexible glue face, the hardness by the design nitrile rubber makes it can not cause the damage of base material.
As shown in Figure 1, mandrel 1 coats the flexible glue face 2 of going up soft, and in order to improve the load-carrying capacity of mandrel 1, material can be selected medium-carbon steel or alloy steel for use, also can select stainless steel material as required for use.Flexible glue face 2 material selection nitrile rubbers also can be selected silaatic for use, to improve service life, its electric conductivity are increased to some extent, can effectively reduce the static that friction produced with plastic basis material, satisfy the flattening of various flexible parent metals, and can not cause its damage.In order to improve the adhesive ability of flexible glue face 2, at the encapsulate place, the roughness that the surface requirements of mandrel 1 is high reaches good in conjunction with effect.
Whole flexible glue face 2 roll surfaces process many equidistant annular rectangular channels 4.Annular rectangular channel 4 has certain angle of inclination angle, and scope is between 70 °～85 °, and annular groove depth is deepened successively from leveling roller roll surface mediad two ends simultaneously.Annular rectangular channel 4 is in the length decision by roll surface of central authorities and the depth difference of end, and roll surface length is short, and the depth difference of circular groove 4 is littler, and roll surface length is big more, and the depth difference of circular groove 4 is big more, and leveling roller is symmetrical to the maintenance of both sides size from the centre simultaneously.Forming annular table 3 at roll surface contacts with base material.By flexible parent metal tension force to going in ring 3 applied pressures of platform, cause the distortion of annular table 3, because annular table 3 has outside angle, the size of annular table 3 outwards increases gradually simultaneously, its outside distortion is also increasing, drives the flexible parent metal that is contacted and extends in the fabric width direction.By the size of appropriate design annular table 3 and circular groove 4, reach desirable flattening effect.Because its flattening characteristics, base material cornerite scope can be greater than 180 °.
Mandrel 1 has adopted solid material, has eliminated the dead space of bleeding, and in the process of encapsulate, guarantees 2 encapsulate layer densification, eliminates bubble and carries secretly, has reduced bleeding the time of vacuum apparatus.
Connect end at mandrel 1 and load onto high-precision bearing, can replace with the idler roller of any cornerite in the equipment.The linear velocity height, noiselessness, stable drive, easy for installation.
The utility model is structurally avoided and has been reduced existence in the unfavorable space of vacuum suction, is applicable under the vacuum condition and uses, and has reduced bleeding the time of vacuum apparatus.
