Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of tire production devices, in particular to an automatic feeding and discharging device for semi-steel radial convex white ring tire production. BACKGROUND

[0002] Semi-steel radial convex white ring tire is a new type of tire in which the body cord is arranged in the radial direction, and the cushion layer with cord arrangement or near-cord arrangement is tightly wrapped around the body. The convex white ring refers to a raised white ring-shaped decoration provided on the tire side and integrally formed with the tire. The semi-steel radial convex white ring tire is composed of six main parts: tread, body, side, cushion layer (or belt), bead, and inner liner (or air tight layer). The stress strength is improved, and compared with the traditional diagonal tire, the semi-steel radial tire has a rigid belt between the tread and the body cord layer, so that when the tire rolls on the road, the circumferential deformation is small, the relative slip is small. Due to the large radial elasticity of the tire body, the tire contact area is increased and the pressure is reduced, so the tread is wear-resistant and puncture-resistant, and the mileage is 30% longer than that of ordinary diagonal tires.

[0003] At present, with the increasing demand for semi-steel radial tires in the market, researchers in related fields have made some improvements to the production efficiency of the equipment for producing semi-steel radial convex white ring tires. For example, the patent document with application number 202410124362.5 discloses an automatic feeding and discharging device for tire production, which discloses that "through the linkage of multiple structures, the automatic feeding, discharging and conveying of the next production process of the tire can be completed in the tire production process; the semi-finished tire to be surface treated can be fixed on the workbench mechanically, compared with the traditional manual feeding, discharging and fixing of the tire, the labor intensity of the workers is reduced, and the efficiency of the tire production is improved".

[0004] However, actual production experience shows that the related device provided by the prior art can realize automatic feeding and discharging in theory, but in actual operation, the tires to be taken are stacked one by one, and the friction and shaking of the clamping structure during transmission and clamping can easily cause the multiple tires in the stacked state to fall, thereby lacking the implementation conditions for subsequent automatic feeding and discharging.
