Multi-piece compression roller assembly and method for manufacturing pneumatic tire

Abstract

The invention discloses a multi-piece compression roller assembly and a method for manufacturing a pneumatic tire. The multi-piece compression roller assembly comprises a lifting lead screw assembly,a power output assembly, a lifting sliding table, a multi-piece pressing roller, a rotary air cylinder, a rotary driver, a swing type falling connecting rod, a swing falling base, an air cylinder set,a rotary shaft support, a swing check block and a head clamping plate. According to the multi-piece compression roller assembly, the head grabbing is carried out by change from materials formerly absorbed by vacuum into a corresponding mechanical structure, so that the falling phenomenon of the head of materials is avoided, and the reliability and the stability of forming equipment is improved. Due to the falling phenomenon affects the whole forming process, the efficiency cost is improved by avoiding the falling. Manual intervention is carried out only by one operator, so that the labor costis saved. In addition, by the automatic feeding and discharging of a forming drum, the manual operation steps are omitted, and the safety risk of the operator is reduced.

Description

technical field [0001] The invention belongs to the technical field of a tire preparation device and a preparation method thereof, and in particular relates to a method for preparing a pneumatic tire with a multi-piece pressing roller assembly. Background technique [0002] At present, most of the functions of the multi-piece pressure roller assembly are only to attach the rubber parts of the rolled tire to the building drum; however, in actual use, the rubber parts often fall during the lamination process. The head of the rolled tire blank rubber part is fixed on the building drum in the early stage of lamination in a certain way, so that the problem of material falling can be avoided. At present, some manufacturers use the vacuum suction cup on the forming drum to absorb the head of the material on the forming drum to assist in completing the drum loading action, but the vacuum suction cup still has the problem of low reliability. Therefore, the present invention aims to ...
