Shoulder wedge feeding frame and front guiding and positioning method thereof

Abstract

The invention relates to a shoulder wedge feeding frame and a front guiding and positioning method thereof. A fixed edge guiding device and method capable of realizing the purpose of pressing downwards, rotating and pushing laterally simultaneously is used for realizing synchronous conveying of two shoulder wedges in limited conveying distance, thereby improving the conveying consistency of the two shoulder wedges to ensure that the two shoulder wedges can be accurately jointed on shoulder positions in parallel. The device is mainly provided with a conveying frame and a conveying template, wherein the conveying template is used for conveying shoulder wedges onto a forming drum and is installed on the conveying frame through a supporting frame. Different from the prior art, at least one group of fixed edge guiding mechanisms are arranged on brackets along the conveying direction of shoulder wedges. The fixed edge guiding mechanisms comprise at least one group of guiding rollers which are axially arranged between brackets at two sides and can axially rotate, and surface rollers of the guiding rollers are spirally arranged along the central line in the transverse direction and the brackets at two sides in the oblique direction. At least two groups of compression rollers which are driven by cylinders are arranged above the guiding rollers in the vertical direction, and the vertical central lines of the guiding rollers and the compression rollers are coincident.

Description

technical field [0001] The invention relates to a tire shoulder pad rubber supply rack used in tire manufacturing and a front guiding positioning method thereof, belonging to the field of rubber machinery. Background technique [0002] At present, in the manufacturing process of all-steel radial tires and semi-steel passenger car tires, it is necessary to transfer the green tires to the forming drum for lamination of shoulder pads on both sides. [0003] The currently used shoulder pad rubber feeder and its conveying technology is to cut the detached pad rubber according to the tire model specifications, and transfer it to the front end through the conveying template to be wound on the carcass. In this process, it is relatively simple to fix the edge or guide the center of the two shoulder pads, and it is easy to have the defect of asymmetric fit, which directly affects the quality of tire production and the safety performance in use. [0004] Such as the prior patent appli...
