Description of drawings
Fig. 1 is the schematic diagram that the former preferred embodiment is made in the roll extrusion of the utility model LGP.
Among Fig. 1, relevant Reference numeral is as follows:
10---the tabula rasa film; 11---the first live roller; 12---the second live roller; 13---the first pressure is regulated roller; 14---the second pressure is regulated roller 15---rolling roller.
The specific embodiment
The basic conception that former is made in the roll extrusion of the utility model LGP is, the employing rolling roller is set, in order to site and the profile mode by roll extrusion is printed on the LGP film.
In order to make those skilled in the art understand better the technical solution of the utility model, the utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Referring to Fig. 1, the schematic diagram of former preferred embodiment is made in the roll extrusion of expression the utility model LGP.This LGP roll extrusion is made former and is comprised that the first live roller 11, the second live roller 12, the first pressure are regulated roller 13, the second pressure is regulated the parts such as roller 14 and rolling roller 15, wherein:
The first live roller 11 and the second live roller 12 are the workpiece transfer unit, are used for support and conveying as the LGP film 10 of workpiece.
The first pressure adjusting roller 13, the second pressure are regulated roller 14 and all can be floated, and wherein the first pressure adjusting roller 13 can contact LGP film 10, the second pressure adjusting roller 14 supports the first pressure adjusting roller 13 into workpiece; These pressure adjustment roll wheels are as the workpiece support parts, in order to play the effect of workpiece support division when the roll extrusion operation, the first pressure is wherein regulated the roll extrusion supporting surface of roller 13 and the roll extrusion working face of rolling roller 15 arranges in opposite directions; By the interoperation of rolling roller 15 with these workpiece support parts, the final realization carried out the roll extrusion operation to the LGP film 10 as workpiece.
