Cart for storing tire second stage building tire blank

Abstract

The invention provides a tire second stage molding wheel blank storage car. A ring tray is supported by a cradle fixedly arranged on a car body. The height of the cradle is higher than the height of the outward raise of a lower entry. The cradle is a ring cylinder or a plurality of support pillars. A lifting mechanism is arranged under a tray inner hole. A round bracket is fixedly positioned at the top end of a piston of the lifting mechanism; the diameter of the bracket is smaller than the diameter of the central hole of a wheel blank; the circumference of the round bracket is articulated and provided with 3 to 6 upper entry brackets at a regular interval; and at an initial status, the external wings of the upper entry brackets slope upwards and inwards. A second stage molding wheel blank is horizontally positioned on the storage car with the tray holding the side and the crest part of the tire, and the lower entry passes through the tray inner hole and sinks. When the wheel blank isdropped down, and the upper entry brackets are caused to turn outwards by a lower tire circle and a concave camber matching with an upper entry rises upwards. The bracket is lifted by the lifting mechanism and the upper entries are held by the upper entry brackets to avoid the deformation of the wheel blank. When the wheel blank is taken out, the bracket falls, and the upper entry brackets are plucked by the lower tire circle to recover to the initial status. The wheel blank storage car can keep the wheel blank from deformation, thereby being convenient in the storage and delivery of second stage molding wheel blank of a huge tire; besides, the wheel blank storage car is simple in structure and convenient in usage.

Description

(1) Technical field [0001] The invention relates to a transportation device for tire blanks in the tire production process, in particular to a two-stage tire blank storage vehicle, which is especially suitable for storing and transporting giant engineering tire two-stage blank blanks. (2) Background technology [0002] A section of the carcass tube of the formed tire blank is expanded on the spreader, and then the carcass is finger-wrapped and buckled on the half-drum building drum, and the rubber core is pressed by the pressure roller, and the shoulder pad rubber is wound and sealed. Carry out turn-up, and wind the sidewall rubber to obtain the second-stage formed tire blank. The bead of the second-stage formed tire blank is not retracted, and the upper and lower bead are respectively tilted to the two sides of the tire. And because the texture of the green tire before vulcanization and setting is soft, it is easy to deform. Especially for giant OTR tires, the tire blank ...

AI Technical Summary

Problems solved by technology

In addition, if there is no special equipment, the surface of the green tire will inevitably be contaminated with mud and oil during storage and transportation.

[0003] The storage and transportation of the second-stage green tire after molding will seriously affect the quality of the tire, and may even lead to the scrapping of the green tire
