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
The present invention relates to a kind of electron beam irradiation device of exudate (Spew) of the fetus face that is used to prevent tire base (Green Tyre), when the tyre vulcanization operation for the exudate of the fetus face that prevents the tire base, and at the fetus face irradiation electronics line of vulcanization process forward direction tire base and carry out spot cure.
Background technology
When making tire, in general make field following enforcement sulfuration operation at tire: the tire base that will finish in the tire building operation is put in the sulfurizing mould, and applying from the inside/outside side under heat and the pressure status through the scheduled time, thereby make the vulcanizing agent and the rubber molecule reaction of in the engagement process of rubber for tire, sneaking into, to obtain the stable intrinsic property of rubber for tire.
At this moment, the rubber of She Ji each several part and reinforcement material etc. are subjected to heat and pressure in mould in advance, and determine certain thickness and position.
Particularly, the exudate of fetus face (Spew) produces in following process: be produced as half-finished size (particularly tread width) difference according to the production schedule in the molding procedure of tire base, therefore produce the mass deviation of tread-rubber, form the exudate that has produced above-mentioned fetus face in the process of pattern with fetus face closing sulfurizing mould at the tire base.
That is, sulfurizing mould is closed, and the tread-rubber of tire base is owing to the flow behavior (viscosity) of rubber is full of the space of the sky of mould, at this moment, if the quality of fetus face rubber produces exudate more at most.
In addition,, then can flow into rubber and mix, thereby have the problem of the inherent characteristic that is difficult to keep sidewall portion to sidewall (Sidewall) portion if the quality of fetus face rubber is more.
On the other hand, in the past as the measure that is used to improve this problem, the mass deviation of fetus face rubber is minimized, and make the generation of exudate and minimize to the inflow of sidewall portion, but because the specification of tire and the variation of pattern, have boundary for the solution of problem, present situation need be developed the technology that can prevent to produce the exudate of fetus face and flow into sidewall portion.
Summary of the invention
Therefore, the present invention is corresponding above-mentioned requirements and the invention that proposes, its purpose is to provide a kind of electron beam irradiation device, it is in order to prevent the exudate of fetus face, and prevent because of in the molding procedure of tire base, being produced the different mass deviations that produce tread-rubber of tread width according to the production schedule, thereby the exudate that causes fetus face flow into sidewall portion, this electron beam irradiation device prevents that by spot cure tyre surface from producing exudate and exudate flow into sidewall portion at this tyre surface irradiation electronics line of sulfuration forward direction of tire mold face.
To achieve these goals, the present invention constitutes and comprises: the wheel rim that expands up and down, and fixedly keep the tire base of multi-size and make this tire base rotation with certain pressure; The electron beam irradiation device, at certain intervals with the tread portion that is disposed at the tire base on the above-mentioned wheel rim that expands up and down from setting; And electronics line screened film, have the electronics line breakthrough part that is disposed between tire base and the electron beam irradiation device, make that the position beyond the fetus face of above-mentioned tire base does not produce electron beam irradiation.
Description of drawings
Fig. 1 is the pie graph of the electron beam irradiation device of the exudate that is used to prevent fetus face of the present invention.
Fig. 2 is the chart of 300% modulus corresponding with the electron beam irradiation amount of expression fetus face.
The specific embodiment
Below describe the present invention with reference to the accompanying drawings in detail.
Fig. 1 is all pie graphs of electron beam irradiation device of the exudate of the expression fetus face that is used to prevent the tire base of the present invention.
The present invention constitutes and comprises: expand up and down wheel rim 2a, 2b, fixedly keep the tire base 1 of multi-size and make it rotation with certain pressure; Electron beam irradiation device 3, at certain intervals be disposed at above-mentioned expand up and down wheel rim 2a, 2b on the fetus face 1a of tire base 1 separate setting; And electronics line screened film 5, it has the electronics line breakthrough part 4 that is disposed between tire base 1 and the electron beam irradiation device 3, so that the position beyond the fetus face 1a of above-mentioned tire base 1 does not produce electron beam irradiation.
The present invention with this structure, by above-mentioned expand up and down wheel rim 2a, 2b with tire base 1 horizontal arrangement and keep certain pressure.The electron beam irradiation device 3 of keeping certain intervals with the fetus face 1a of this tire base 1 and fixedly installing, when tire base 1 and above-mentioned wheel rim 2a, the 2b of expanding up and down when the arrow A direction is rotated, can shine the electronics line of certain hour to the fetus face 1a of tire base 1 equably.Promptly, tire base 1 is produced with various specification according to the production schedule in molding procedure, therefore for to desirable fetus face 1a irradiation electronics line, solid line and imaginary line state move and the length of regulating electronics line breakthrough part 4 in the drawings can to make above-mentioned electronics line screened film 5.At tire base 1 when the arrow B direction moves and has arrived the precalculated position, detect this situation by known sensor, up-down adjustment electronics line screened film 5 and the length of regulating electronics line breakthrough part 4, thus make the electronics line of irradiation or not other positions of tire base 1 and only shine fetus face 1a.
Produce spot cure by electron beam irradiation device 3 to the fetus face 1a of tire base 1 irradiation electronics line like this, can in the little scope of the mass deviation of the fetus face 1a of tire base 1, make exudate in the sulfurizing mould produce and minimize, can not flow into exudate simultaneously to sidewall portion.
On the other hand, referring to the chart of 300% modulus (Modulus) corresponding of the fetus face 1a of the expression tire base 1 of Fig. 2 with the electron beam irradiation amount.Half-finished 300% modulus comparative result that the electron beam irradiation of above-mentioned graphical presentation by fetus face 1a obtains, the electron beam irradiation amount is many more, and 300% modulus is also high more.That is, along with the electron beam irradiation amount increases, spot cure, elasticity increases, and the viscosity of rubber reduces simultaneously.
The electron beam irradiation device of the exudate of the above-mentioned fetus face that is used to prevent the tire base, carry out spot cure by fetus face irradiation electronics line, in sulfurizing mould, when sulfuration, can make the exudate of tyre surface minimize and prevent the effect that exudate flows into to sidewall portion thereby have at vulcanization process forward direction tire base.
