Description
Technical field:
The invention belongs to tire processing and manufacturing technical field, relate to a kind of carcass of old tire or reproducing method that tire jacking row is prepared into the process, particularly a kind of rubber tyre of new tire again of utilizing.
Background technology:
At present in the tire production manufacture process, can produce position defectiveness such as part sidewall and circle mouth, but the tire that the tire top is intact, existing this part tire is all scrapped processing, causes the wasting of resources, in order to take full advantage of these resources, the design and propose a kind of brand-new tire again manufacturing process economic worth is arranged very much, this production technology more both had been different from traditional tyre rebuilding, also was different from existing new tire production.In addition, along with the quick increase of automobile use amount, application quality and the quantity of tire are also more and more higher, and the raw materials for production of tire also more and more lack.In the tire manufacturing process of routine, tire earlier will be by the banburying operation before making, the material of making tire is produced sizing material, sizing material will be tested before entering subsequent processing, just can enter next step glue component preparatory process, the preparatory process of glue component is divided into 6 workshop sections, and the one, extrude workshop section, sizing material enters extruder head, extrudes different semi-finished product glue: parts such as tyre surface, sidewall, rim of the mouth and apex strip; The 2nd, calender passes with the raw material cord in calendering workshop section, and last finished product is carcass; The 3rd, the tyre bead pressing section is entwined after making tyre bead that many steel wire kiss-coatings be arranged; The 4th, the cord severing, cord is become suitable width and connects joint by severing; The 5th, paste apex strip, the apex strip that extruder is extruded by manual assembly to tyre bead; The 6th, the belt moulding, between spindle, many steel wires come out by eyelet strip, pass die panel simultaneously with sizing material again, make steel wire two sides kiss-coating, and belt is blocked into angle and the width of regulation behind the kiss-coating; Deliver to the tire building operation then, semifinished part is assembled into green tire at make-up machine, send into vulcanization process again, green tire is installed on the vulcanizer, after finished tire is made in sulfuration, the operation of testing again.Understanding some tire in existing these preparation process has incomplete tire because a variety of causes becomes, the utilization of these incomplete tires becomes the scheme that prior art is being inquired into.But at present, these incomplete tires mainly are to reclaim to refine glue and use again, and are about to incomplete tire and carry out again processing and preparing as rubber raw materials and become the product rubber raw materials; In the incomplete tire of prior art, various defect problems such as its incompleteness mainly contains that bubble in the sidewall, the tire ear is discontented, sidewall incipient scorch and carcass distortion, the defective goods rate that goes out of existing production technology and technology is about 2%-5%, can cause the waste of various resources at present to the recycling mode of these incomplete tires, and the recycling power consumption is bigger, and environment is unfriendly.
Summary of the invention:
The objective of the invention is to overcome the shortcoming that prior art exists, seek to design a kind of reproducing method of rubber tyre, qualified tire top in the solution tire production process or in the junked tire and the re-using problem of carcass, adopt composite regenerated formula processing and preparing technology, become the qualified new tire of finished product qualified tire tire top and carcass are composite regenerated.
To achieve these goals, the present invention tire is pushed up defective old tire earlier or new tire uses cutting equipment by the separation cuts technology tire to be pushed up and the carcass separation cuts, obtain complete qualified carcass, the back combined type of being polished respectively in the qualified tire top of qualified carcass and cutting and separating or new processing and preparing again constitutes complete tire embryo, send into again in the conventional vulcanizing equipment and vulcanize, finish tire manufacturing process again; Its specific implementation process comprises that the preparation of tire top, carcass preparation, embryo synthesize, vulcanize typing and five steps of finished product detection:
(1) tire top preparation: push up intact tire and the defective new tire in other positions earlier, classify by model, decorative pattern, again the tire top is carried out cutting and separating along tire shoulder portion from tire, cutting and separating adopts the artificial cutting equipment enforcement of implementing or adopt, tire top after the cutting and separating should be regular, its tangent plane and tire central shaft keeping parallelism; Then, the fluffing of polishing of the tire top medial surface after the cutting and separating is handled, the polishing fluffing is handled to adopt and is manually implemented or adopt grinding apparatus to implement, and can not destroy inner belt during polishing, carries out dust removal process again after the polishing fluffing; At last, brushing rubber cement on the tire top medial surface of polishing fluffing forms the spare tire top;
(2) carcass preparation: select the satisfactory qualified carcass after the separation cuts for use, or select for use conventional first stage building machine according to same model tyre production technology and the material requirements of routine, make forming carcass, again the carcass outer surface is polished to fluff and handle, form standby carcass;
(3) embryo is synthetic: the spare tire top of selecting for use conventional second stage building machine to have handled well is wrapped on the standby carcass and carries out moulding, forms the tire embryo;
(4) sulfuration typing: the tire embryo of forming is put into conventional tyre vulcanizer carry out first cure, make compound recycled product tire;
(5) finished product detection: the recycled product tire to preparation detects, and qualified tire is packaged into the product tire, defective tire is carried out cutting and separating again handle or the waste recovery utilization.
The present invention relates to the tire cutting and comprise hand cutting tool cutting and the cutting of tire cutting and separating machine; Tire curing unit is conventional fair product, comprises the radial vulcanizer that the ZL2009200252204 patent relates to; The tyre reconditioning vulcanizer that the ZL2011202270416 patent relates to, or the tyre reconditioning vulcanizer that relates to of 2011101786747 patents; The carcass grinding apparatus adopts conventional rubber polishing structure, realizes that the tire top outer surface after the polishing constitutes hair line structure.
The present invention compared with prior art, its design technology principle is simple, processing cost is low; Tire top bonding and sulfuration with carcass with waste tire reduces processing step, and is simple to operate, energy-conserving and environment-protective, refuse reclamation, environmental friendliness.
