Doubling hot pack device of belted layer and doubling hot pack production process

Abstract

The invention discloses a doubling hot pack device of a belted layer, comprising a gluing and edge-binding conveyer belt, unwinding equipment for unwinding a belted layer cord fabric, a centering device, an extruder for providing model glue synchronously and a feeding device and a calendar thereof, a gluing device for gluing the model glue with the belted layer cord fabric, a edge-binding device for carrying out edge-binding on the model glue and the belted layer cord fabric, an air-cooling system for cooling the belted layer after the gluing and edge-binding process is finished, and a rolling apparatus for rolling up the cooled belted layer cord fabric. The invention also discloses a doubling hot pack production process using the device; the off-line doubling hot pack device of the invention is separated from the cutting production line so that the whole production efficiency can be improved. The hot gluing and edge-binding are adopted, and bending is carried out gradually by utilizing the good ductility and stickiness of the hot type glue, thereby reducing bubbles and improving the production quality. Meanwhile, different grooves are arranged on a roller according to the model glues designed by different customers so as to meet the requirements on the customers and improve the customer satisfaction.

Description

technical field [0001] The invention belongs to the technical field of tire machinery, and in particular relates to a laminating and hemming device for belt cords and a production process for using the device to carry out lamination hot-packing. Background technique [0002] At present, belt ply cutting machines are usually used in tire manufacturing to cut the belt ply into parallelogram-shaped belt ply strips according to the width and angle requirements set by the process, and then cut the belt ply ply strips in order Splicing is performed automatically, and then the two sides are laminated and wrapped, and finally wound into a certain required reel for the next forming tire blank. [0003] The prior art belt ply cutting machine and the bonding and hemming mechanism are integrated into one production line, which mainly includes a guide mechanism, a fabric storage mechanism, a fixed-length conveying mechanism, and a shearing mechanism, which are connected in sequence betwe...

Problems solved by technology

[0005] 1. Because the existing hemming is cold-wrapped and cold-applied film, the cold film has poor flexibility and ductility, and air bubbles are prone to occur in the belt layer after laminating and hemming, which has a great impact on the quality of the tire;

[0006] 2, figure 1 It is a schematic cross-sectional view of the belt layer after hemming in the prior art; figure 2 Schematic diagram of the cross-section of the belt layer with a certain shape for the fit section belt; such as figure 1 , figure 2 As shown, the molding rubber 200 on both sides of the all-steel radial tire belt layer 100 in the prior art is a strip structure with uniform thickness. There is a certain shape, that is, the film needs to have different shapes, which are called type glue below, such as figure 2 As shown in the medium glue 300, this makes it more difficult to prepare the mold glue into rolls, and it cannot be completed by cold lamination
