Description
Technical field
It the utility model is related to the technical field of PU leathers production, and in particular to a kind of crimping of concave convex texture PU leathers
Roller.
Background technology
PU is English poly urethane abbreviation, chemical Chinese " polyurethane ".PU leathers be exactly polyurethane into
The epidermis of part.It is widely used in makeing the decoration of case and bag, clothes, footwear, vehicle and furniture now, it has increasingly obtained agreeing for market
Fixed, its application is wide, and quantity is big, as many as kind, is that traditional natural leather can not meet.Its quality of PU leathers
There are quality, good PU skins even, fixed effect good surface-brightening also more expensive than corium price.
PU leathers are widely used in the fields such as sofa, case and bag, leather shoes, belt, decorative cover.Other PU leathers can also be used for
Decoration, i.e., PU leathers are wrapped in the surface of some objects, so as to improve the aesthetic feeling of the object and class.But current PU leathers
Itself all it is monochromatic, without decorative pattern, it is all solid color to cause the object of decoration out；If it is intended to pass through PU leather bags
If wrapping up in object and forming decorative pattern, it is necessary to which the PU leathers of a variety of different colours carry out cutting and are spliced.This mode is not only
Operation construction is complicated, and cost is higher.Construction effect is also limited to the technical merit of workmen.If it is intended to show recessed
Convex effect, it is also necessary to which multiple PU leathers are carried out stacking construction by workmen, and difficulty of construction is bigger.
Moreover, also do not produce the special processing equipment of concave-convex effect for PU leathers on the market at present.
The content of the invention
The purpose of this utility model is：A kind of overcome the deficiencies in the prior art, there is provided crimping of concave convex texture PU leathers
Roller, bar-shaped trough is provided with upper pressure roller, and strip bulge is provided with corresponding to bar-shaped trough on lower compression roller, so as to be passed through in PU leathers
When crossing pressure roller and lower compression roller, once bar-shaped trough is mutually engaged with strip bulge, then PU leathers is subjected to crimping, makes PU leathers
Surface forms concave convex texture；Spacing at the top of the bottom land and strip bulge of bar-shaped trough is equal to the spacing between upper pressure roller and lower compression roller
And the spacing between the cell wall of bar-shaped trough side wall corresponding with strip bulge is equal to the spacing between upper pressure roller and lower compression roller, from
And extruding positioning is carried out to PU leathers while crimping, prevent PU leathers from causing crimping due to itself flexibility and retractility
Failure；The diameter of upper pressure roller and lower compression roller is equal, and rotating speed is equal, so as to improve contract when bar-shaped trough is engaged with strip bulge
It is right.
Technical solution adopted in the utility model is：
The crimping roller of concave convex texture PU leathers, include the upper pressure roller and lower compression roller of mutual cooperation, the upper pressure roller is with pushing
The thickness for being smaller than PU leathers between roller, the arc surface of the upper pressure roller are uniformly provided with more axially arranged bar-shaped troughs,
The arc surface of the lower compression roller corresponds to bar-shaped trough and is respectively equipped with the strip bulge of respective amount, between adjacent two bar-shaped troughs
Cambered surface between cambered surface distance and adjacent two strip bulges is apart from equal, and the linear velocity and lower compression roller of upper pressure roller arc surface
Arc surface linear velocity it is equal, and the steering of upper pressure roller and lower compression roller is opposite.
The further improvement project of the utility model is, when upper pressure roller and lower compression roller turn to bar-shaped trough and be engaged with strip bulge
When, the spacing at the top of the bottom land and strip bulge of the bar-shaped trough is equal to the spacing between upper pressure roller and lower compression roller.
The further improvement project of the utility model is, when upper pressure roller and lower compression roller turn to bar-shaped trough and stung with strip bulge
During conjunction, between the spacing between the cell wall side wall corresponding with strip bulge of the bar-shaped trough is equal between upper pressure roller and lower compression roller
Away from.
The further improvement project of the utility model is that the rotating shaft A of the upper pressure roller and the rotating shaft B of lower compression roller pass through transmission
Device is connected.
The further improvement project of the utility model is that the diameter of the upper pressure roller and lower compression roller is equal, and rotating speed is equal.
The beneficial effects of the utility model are：
Firstth, the crimping roller of concave convex texture PU leathers of the present utility model, is provided with bar-shaped trough on upper pressure roller, and under
Strip bulge is provided with corresponding to bar-shaped trough on pressure roller, so that when PU leathers pass through upper pressure roller and lower compression roller, once bar shaped
Groove is mutually engaged with strip bulge, then PU leathers is carried out into crimping, PU leather surfaces is formed concave convex texture.
Secondth, the crimping roller of concave convex texture PU leathers of the present utility model, at the top of the bottom land and strip bulge of bar-shaped trough
Spacing is equal to spacing of the cell wall of the spacing and bar-shaped trough between upper pressure roller and lower compression roller with strip bulge between corresponding side wall
The spacing being equal between pressure roller and lower compression roller, so as to carry out extruding positioning to PU leathers while crimping, prevent PU skins
Remove from office due to itself flexibility and retractility and cause crimping to fail.
3rd, the crimping roller of concave convex texture PU leathers of the present utility model, the diameter of upper pressure roller and lower compression roller is equal, rotating speed
It is equal, so as to improve compatible degree when bar-shaped trough is engaged with strip bulge.
