Description

Technical Field

[0001] The utility model belongs to the technical field of electron accelerators, in particular to an electron beam radiation pre-vulcanization device for an inner liner of an all-steel tire. Background Art

[0002] Electron beam pre-vulcanization refers to the use of electron beams to irradiate rubber products so that the rubber molecules can achieve a certain degree of cross-linking, which can effectively reduce the amount of rubber used, thereby saving costs; at the same time, it ensures product quality, shortens the later vulcanization time, and improves production efficiency. In real life, when the inner liner of an all-steel tire is pre-vulcanized, the inner liner film is transmitted to the electron beam radiation box through a transmission mechanism for pre-vulcanization. Since most electron beam radiation pre-vulcanization devices are not equipped with a tensioning component, it is impossible to adjust the tension of the inner liner film on the transmission mechanism. When the inner liner film becomes loose, it is easy to fall off the transmission mechanism, thereby affecting the pre-vulcanization of the inner liner film.

[0003] A Chinese patent document (application publication number CN220242490U) discloses an electron beam radiation pre-vulcanization device for an inner liner of an all-steel tire, which includes a shielding room arranged on a support frame, and an electric vacuum system for generating an electron beam arranged in cooperation with the shielding room, wherein the electric vacuum system includes an electron gun, an accelerating tube and a scanning extraction device, and an external shielding and transmission component is arranged on the outside of the shielding room.

[0004] It can be seen that the patent document cited above also has the same problem. Although it realizes the small modular and integrated layout of the equipment, it lacks a tensioning component, making it impossible to adjust the tension of the material on the transmission component. When the material becomes loose, it is easy to fall off the transmission mechanism, thereby affecting the pre-vulcanization treatment of the material. Utility Model Content

[0005] The utility model aims to provide an electron beam radiation pre-vulcanization device for an inner liner of an all-steel tire, so as to solve the problems raised in the background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an electron beam radiation pre-vulcanization device for the inner liner of an all-steel tire, comprising an electron beam radiation box for pre-vulcanization treatment of the inner liner of an all-steel tire, which is arranged at the top of a processing table, a vertical plate is installed on the side of the top of the processing table, a plurality of transmission rods are installed on one side of the vertical plate, an inner liner film is commonly arranged between the plurality of transmission rods, and a tensioning assembly is arranged at the top of the vertical plate.

[0007] The tensioning assembly includes a fixed block, the top of which is equipped with a first screw rod, the top of which is equipped with a first torque, the bottom of which is equipped with a connecting block, the inner side wall of which is equipped with a pressure rod, and the bottom end of the pressure rod contacts the top of the inner lining film.

[0008] As a preferred embodiment, a second screw rod is provided through one side of the outermost transmission rod, a second torque is installed at one end of the second screw rod, and a limiting rod is installed on the outer wall of the second screw rod, and one side of the limiting rod is in contact with one side of the inner lining film.

[0009] As a preferred embodiment, a guide rod is installed at the top of the connecting block, and the outer wall of the guide rod passes through the top of the fixing block.

[0010] As a preferred embodiment, the other end of the second screw rod is connected to a bearing at one end of the inner wall of the transmission rod.

[0011] As a preferred embodiment, a through slot is formed at the top end of the outer wall of the transmission rod, and the inner side of the through slot is slidably connected to the outer side of the limiting rod.

[0012] As a preferred embodiment, fixing grooves are provided on both sides of the electron beam irradiation box, and the outer wall of the inner lining film passes through the two fixing grooves.

[0013] As a preferred embodiment, the back side of the electron beam irradiation box is fixedly connected to one side of the vertical plate.

[0014] Compared with the prior art, the technical effects and advantages of the utility model are as follows:

[0015] The electron beam radiation pre-vulcanization device for the inner liner of the all-steel tire benefits from the design of the first turning knob, the connecting block and the pressure rod. The first turning knob is turned to drive the first screw rod to move downward. The first screw rod moves downward to drive the pressure rod to move downward through the connecting block until the pressure rod tensions the surface of the inner liner film. In this way, the tension adjustment of the inner liner film is convenient, so that the inner liner film is prevented from being loose and easily falling off the transmission rod, thereby not affecting the pre-vulcanization treatment of the inner liner film.

[0016] By providing a second torque, a second screw rod and a limit rod, rotating the second torque drives the second screw rod to rotate, and then drives the limit rod to move left and right. This method can limit the inner lining film of different widths to meet various needs. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] The present embodiment provides a second screw rod 7 penetrating one side of the outermost transmission rod 5, the outer wall of the second screw rod 7 is connected to a bearing at one end of the transmission rod 5, a second twist 8 is installed at one end of the second screw rod 7, the outer wall of the second twist 8 is also provided with an anti-slip thread, and the outer wall of the second screw rod 7 is equipped with a limiting rod 9, and one side of the limiting rod 9 is in contact with one side of the inner lining film 6.

[0030] In this embodiment, a guide rod 405 is installed on the top of the connecting block 404, and the outer wall of the guide rod 405 passes through the top of the fixed block 401. The guide rod 405 is slidably connected to the fixed block 401, and the connecting block 404 is guided and limited by the guide rod 405.

[0033] How it works

[0034] First, according to the width of the inner lining film 6, the second knob 8 is rotated. The rotation of the second knob 8 drives the limiting rod 9 to move left and right through the second screw rod 7. In this way, the inner lining film 6 of different widths can be limited to meet various needs. Secondly, one end of the inner lining film 6 is passed through several transmission rods 5 on one side of the electron beam radiation box 3, and penetrates the electron beam radiation box 3 through two fixed grooves 301 on the electron beam radiation box 3, and then passes through several transmission rods 5 on the other side of the electron beam radiation box 3. When the inner lining film 6 is transmitted for pre-vulcanization treatment, the first knob 403 is rotated. The first knob 403 drives the connecting block 404 to move downward through the first screw rod 402 until the pressure rod 406 tightens the surface of the inner lining film 6. In this way, the inner lining film 6 is conveniently tensioned and adjusted, thereby preventing the inner lining film 6 from loosening and easily falling off the transmission rod 5, thereby not affecting the pre-vulcanization treatment of the inner lining film 6.
