Abstract
The invention discloses a thin film wind-up roll comprising a wind-up roll body, wherein an elastic surface layer is arranged on the surface of the wind-up roll body and is a foaming sponge layer. With the adoption of the technical scheme, the thin film wind-up roll has the beneficial effects that the surface of the wind-up roll is additionally provided with the elastic surface layer, after the thin film is rolled, the elastic surface layer plays a role in the cooling shrinkage process, thus buffering the shrinkage, therefore, the wind-up roll and the whole thin film can be protected from deforming due to the shrinkage of the thin film after being rolled.
Description
Technical field:
The present invention relates to a kind of film take-up roller.
Background technology:
The production of film all is flow casting molding or blow molding generally, and the film after the moulding needs special wrap-up that it is carried out rolling, and in actual production; Because the film of harsh output has certain heat, in film take-up behind wind-up roll, because the cooling shrinkage of film; It can produce pressure to wind-up roll; After pressure acquires a certain degree, will make wind-up roll produce distortion, and then cause whole volume film rolling to deform.
Summary of the invention:
The objective of the invention is in order to overcome the shortcoming of above-mentioned prior art, a kind of film take-up roller of avoiding causing because of cooling shrinkage because of the film after the rolling distortion is provided.
Goal of the invention of the present invention can realize through following technical scheme: film take-up roller, include the wind-up roll body, and on the surface of wind-up roll body, be provided with one deck elasticity top layer.
The elasticity top layer is for sending out foam sponge layer.
The wind-up roll body is a paper bowl.
The wind-up roll body is a plastic roller.
After adopting the present technique scheme; The invention has the beneficial effects as follows: increase one deck elasticity top layer on the surface of wind-up roll; After film take-up, in the process of cooling shrinkage, the elasticity top layer plays a role; Cushion this contraction, thereby avoid because of film shrinks wind-up roll and whole volume film being deformed after the rolling.
Description of drawings:
Fig. 1 is the constructional drawing of film take-up roller of the present invention;
Fig. 2 is the constructional drawing of film rolling of the present invention.
The specific embodiment:
Below in conjunction with accompanying drawing present technique is described further.
The film take-up roller of present embodiment includes wind-up roll body 1, on the surface of wind-up roll body 1, is provided with one deck elasticity top layer, and the elasticity top layer is for sending out foam sponge layer 2, and wind-up roll body 1 is paper bowl or plastic roller.After film 3 rollings, in cooling process, film 3 cooling shrinkages, send out foam sponge layer 2 and receive the effect of convergent force and be compressed distortion this moment, thereby cushioned film 3 amounts of contraction, avoids the distortion of wind-up roll and film rolling.
The above only is preferred embodiment of the present invention, is not the present invention is done any pro forma restriction.Any those of ordinary skill in the art; Do not breaking away under the technical scheme scope situation of the present invention; All the method for above-mentioned announcement capable of using and technology contents are made many possible changes and modification to technical scheme of the present invention, or are revised as the equivalent embodiment of equivalent variations.So every content that does not break away from technical scheme of the present invention, the equivalence of doing according to the present invention's shape, structure and principle changes, and all should be covered by in protection scope of the present invention.
