Description
Technical field
The invention belongs to the tire machinery technical field, particularly relate to and a kind ofly be used for the applying Wrapping apparatus of bracing ply cord and use this device to carry out the production technology of doubling heat bag.
Background technology
Usually adopt the bracing ply cord fabric cutting machine bracing ply cord to be become the bracing ply curtain fabric strips of parallelogram shape with angle requirement severing by the width of technique initialization in the tire manufacturing at present, bracing ply curtain fabric strips with institute's severing splices in regular turn automatically then, again dual-side is carried out film afterwards and fit and bound edge, coil into necessarily required spool at last for preface building green tyre use down.
The bracing ply cord fabric cutting machine of prior art and applying edge covering mechanism are incorporated into a manufacturing line, and this manufacturing line comprises mainly that mouth and input end link to each other in regular turn leads opening mechanism, storage cloth mechanism, fixed length conveying mechanism, cutting mechanism, bracing ply conveying mechanism, detent mechanism, splicing body, shedding mechanism, applying edge covering mechanism and spooler.Its working process is at first to utilize to lead opening mechanism the bracing ply cord is separated with isolation shield on being coated on its two sides, on the one hand isolating pad cloth being batched the back reclaims, by storage cloth mechanism the bracing ply cord is flowed to the fixed length conveying mechanism on the other hand, the fixed length conveying mechanism again with bracing ply cord fixed length, decide angle and be transported to cutting mechanism, and cut into parallelogram bracing ply curtain fabric strips by cutting mechanism.Bracing ply curtain fabric strips after the shearing is transported to by the bracing ply conveying mechanism on the applying bound edge load-transfer device of detent mechanism, and the process detent mechanism is delivered to splicing body and splices automatically again.Spliced bracing ply cord is transported to the applying edge covering mechanism by shedding mechanism, fitting and bound edge according to different technological requirements, is rolled into required volume by the bracing ply cord of spooler after with the applying bound edge at last, uses for next process.
But existing applying bound edge is cold adhesive type glue, cold bound edge for applying and the bound edge that carries out on low-angle severing manufacturing line, promptly in advance rolling is made and twined to the bound edge film, then the bound edge of fitting is led out and implemented to film by the speed that is complementary with the bracing ply cord, the major defect of this technology is:
1, because existing applying bound edge is the cold rubberizing sheet of cold bound edge, cold rubber piece flexibility and poor ductility are easy to generate bubble in the bracing ply behind the applying bound edge, and the quality of tire is had a significant impact;
2, Fig. 1 is the bracing ply schematic cross-section behind the prior art bound edge; The bracing ply schematic cross-section that Fig. 2 has definite shape for applying section band; As shown in Figure 1 and Figure 2, the all-steel meridian tire bracing ply 100 both sides type glue 200 of prior art are the uniform list structure of thickness, development along with technology, all-steel meridian tire bracing ply 100 requires the section of applying adhesive tape to have definite shape, promptly need film to have different shapes, below be referred to as type glue, shown in the medium-sized glue 300 of Fig. 2, this just makes the preparation rolling difficulty increase earlier of type glue, can not finish by cold applying form.
