Problems solved by technology

[0006] In addition, if the mass of rubber in the tread portion is large, the rubber will flow into the sidewall portion and be mixed, and there is a problem that it is difficult to maintain the inherent characteristics of the sidewall portion.
[0007] On the other hand, in the past, as a measure for improving this problem, the quality deviation of the rubber in the tread portion was minimized to minimize the generation of exudate and the inflow to the sidewall portion. Diversification, there is a limit to the solution of the problem, the current situation requires the development of technology that can prevent the leakage of the tread part and the flow into the sidewall part

Embodiment Construction

[0012] The present invention will be described in detail below with reference to the accompanying drawings.

[0013] figure 1 It is a diagram showing the overall configuration of an electron beam irradiation device for preventing exudation from a tread portion of a green tire according to the present invention.

[0014] The present invention is constituted to include: upper and lower expansion rims 2a, 2b, which fix and maintain tire blanks 1 of various specifications under a certain pressure and make them rotate; electron beam irradiators 3 are arranged on the above-mentioned upper and lower expansion rims 2a, 2b at a certain interval. The tread portion 1a of the green tire 1 is provided separately; and the electron beam shielding film 5 has the electron beam penetration portion 4 arranged between the green tire 1 and the electron beam irradiator 3, so that the tire on the green tire 1 Parts other than the face 1a were not irradiated with electron beams.

Abstract

The invention provides an electron beam emission apparatus for rubber spew prevention of a tire tread. An electron beam is irradiated to the tire tread of the tire mold for local vulcanization before the vulcanization process in order to prevent the spew on the tire tread of the tire mold in the vulcanization process of tire.

Description

technical field [0001] The present invention relates to an electron beam irradiation device for preventing spew from the tread portion of green tires, which is used during vulcanization to prevent spew from the tread portion of green tires during tire vulcanization. Partial vulcanization is performed by irradiating electron beams to the tread portion of the green tire before the process. Background technique [0002] When manufacturing tires, vulcanization is generally carried out in the tire manufacturing field as follows: the green tire completed in the tire building process is placed in a vulcanization mold, and a predetermined time elapses while heat and pressure are applied from the inside / outside , so that the vulcanizing agent mixed in the compounding process of the tire rubber reacts with the rubber molecules to obtain the stable inherent properties of the tire rubber. [0003] At this time, the pre-designed rubber and reinforcing materials of each part are subjecte...
