Embodiment 1

[0041] Example 1, such as figure 1 As shown, the tire film electronic irradiation crosslinking pretreatment device mainly includes an irradiation room 1 , a shielding room 2 , a conveyor belt 3 and an electron accelerator 4 . in,

[0042] On the inner walls of the irradiation room 1 and the shielding room 2, there are all attached ray-absorbing plates that can be made of lead plates or stainless steel plates.

[0043] An electron accelerator 4 is arranged inside the irradiation chamber 1 and above the conveyor belt 3,

[0044] The conveyor belt 3 is a stainless steel wire mesh structure as a whole, and extends through the irradiation room 1 and the shielding room 2 . The gap between the conveyor belt 3 and the entrance and exit of the irradiation chamber 1 and the shielding chamber 2 is 3-6 cm, so as to minimize the space for radiation leakage under the premise of allowing the conveyor belt 3 to carry the film through.

[0045] The conveyor belt 3 includes a horizontal conv...

Abstract

The invention discloses a tire rubber sheet electron radiation crosslinking pretreatment device and a tire rubber sheet electron radiation crosslinking pretreatment method. A conveyor belt used for realizing an arc-shaped conveying track is arranged in a shielding room; based on the ray absorption by the interior wall of the shielding room, the ratio of attenuation generated by multiple times of refraction is increased by increasing the reflection times of rays, and thus, the rays can be absorbed to a maximum degree and the ray leakage can be reduced so as not to pollute the environment and hurt the body the operators. The device mainly comprises a radiation room, the shielding room and the conveyor belt for conveying rubber sheets, wherein an electron accelerator is arranged in the radiation room and above the conveyor belt, and the conveyor belt runs through the radiation room and the shielding room. Ray absorbing plates are adhered on all of the inner walls of the radiation room and the shielding room. The conveyor belt comprises a horizontal conveying part arranged in the radiation room and below the electron accelerator and an oblique conveying part arranged in the shielding room. The oblique conveying part has at least one group of left and right symmetric and vertically bent continuous conveying section.

Description

technical field [0001] The tire film electronic radiation crosslinking pretreatment device and method thereof described in the present invention are applied to the radiation crosslinking pretreatment of tire film, and belong to the technical field of rubber machinery and electronic radiation. Background technique [0002] With the continuous innovation of rubber tire manufacturing technology, it is imperative to improve the film vulcanization equipment and process using traditional technology. [0003] Compared with the traditional method of vulcanizing the film by applying pressure and heating to the drum or flat vulcanizer, the high-energy electron beam is used to irradiate the surface of the film to excite and ionize the rubber molecules and generate free radicals to achieve intermolecular crosslinking and vulcanization , can not only achieve the same thermal vulcanization effect, but also reduce the complexity of equipment structure and operation process, and can signifi...
