Tyre building machine

Abstract

The invention relates to a tyre building machine which comprises an operating floor, a feed table and a drive control bin. A first feed roller and a second feed roller are arranged on the feed table;a sliding support frame and a multilayer pre-laminating device are arranged on the operating floor; a tyre building drum is arranged between the sliding support frame and the multilayer pre-laminatingdevice; a rotary shaft is arranged in the tyre building drum in a penetrating way; one end of the rotary shaft is connected with a support frame pivot hole on the sliding support frame in an embedding way; the other end of the rotary shaft is connected with a roller joining pipe arranged in the multilayer pre-laminating device in an embedding way; a pre-laminating motor is arranged in the drive control bin; a cylindrical through hole is formed in the roller joining pipe; a first bearing and a second bearing are arranged at two ends of the through hole; the first bearing enables a connector ofthe rotary shaft to be locked into the through hole; and the second bearing in the through hole enables a motor rotary shaft to be locked and pivotly connected into the roller joining pipe. The invention provides the tyre building machine capable of folding and pressing multiple layers of sheets into a tyre semi-finished product and capable of realizing convenient pre-laminating treatment on thetyre semi-finished product.

Description

technical field [0001] The invention relates to the field of mechanical production, in particular to the field of tire building, in particular to a tire building machine. Background technique [0002] Tires are circular elastic rubber products that are rolled on the ground and rolled on various vehicles or machinery. In 1845, R.w. Thomson, a civil engineer born in Scotland, invented the pneumatic tyres, and obtained a patent from the British government under the title of "Wheel Improvement for Carriages and Other Vehicles". On December 10 of the same year, the first pneumatic tire was born. Tires are usually installed on metal rims, which can support the vehicle body, buffer external impacts, realize contact with the road surface and ensure the driving performance of the vehicle. [0003] Tires are often used under complex and harsh conditions, and they are subjected to various deformations, loads, forces, and high and low temperature effects during driving, so they must h...

Problems solved by technology

[0004] In the prior art, the production of tires is relatively complicated, and the sheets need to be wound and laid layer by layer, and then cured by heating. The pre-pressing operation of multi-layer sheets of tire semi-finished products, without pre-pressing, it is easy to leave air gaps between each layer of sheets, which will affect the molding effect of the tire during curing

As a result, the quality of the finished tire is problematic, causing potential safety hazards during use; at the same time, after the tire semi-finished product is produced, it is generally necessary to remove the tire semi-finished product before proceeding to the next step, and it cannot be directly transferred to the pre-pressing device for pre-pressing treatment
