Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0022] Please refer to Figures 1-4 , an embodiment of the present utility model is: a cutting device for processing foamed rubber tires, including a base 1. The top of the base 1 is rotatably connected to a first rotating rod 2 through a bearing. The top end of the first rotating rod 2 is fixedly connected to a workbench 3. The interiors of both the base 1 and the workbench 3 are hollow. A fixing mechanism 4 is arranged on the workbench 3, and a cutting mechanism 5 is arranged on the base 1; The fixing mechanism 4 includes: sliding grooves 41, a second rotating rod 45. The number of sliding grooves 41 is two. The two sliding grooves 41 are oppositely opened on the top of the workbench 3. The inner wall of each sliding groove 41 is slidably connected to a slider 42. The top of each slider 42 is fixedly connected to a fixing block 44. The opposite surfaces of the two sliders 42 are respectively fixedly connected to a spring 43, and the other ends of the two springs 43 are respectively fixedly connected to the inner walls of the two sliding grooves 41. The second rotating rod 45 is rotatably connected to the top of the workbench 3 through a bearing. The top end of the second rotating rod 45 is fixedly connected to a push plate 46. The push plate 46 is elliptical in shape, and its outer wall is respectively in contact with the two fixing blocks 44. The bottom end of the second rotating rod 45 extends into the interior of the workbench 3. The bottom end of the second rotating rod 45 is fixedly connected to an adjusting gear 47. A first electric telescopic rod 48 is fixedly installed on the inner wall of the workbench 3. The piston end of the first electric telescopic rod 48 is fixedly connected to a rack 49. The rack 49 is meshed with the adjusting gear 47. After placing the tire on the workbench 3, the first electric telescopic rod 48 is started to drive the rack 49 to move. The rack 49 drives the adjusting gear 47 and the second rotating rod 45 to rotate, thereby driving the push plate 46 to rotate and push the fixing block 44, so that the fixing block 44 drives the slider 42 to slide along the inner wall of the sliding groove 41 and stretch the spring 43, so that the two fixing blocks 44 move away from each other and tightly fix the tire. And the push plate 46 is set to be elliptical, which can adjust the distance between the two fixing blocks 44 according to the size of the tire, facilitating the fixation of tires of different sizes and improving the applicability of the device. The cutting mechanism 5 includes: a support frame 51. The support frame 51 is fixedly connected to the top of the base 1 and is located behind the workbench 3. The support frame 51 is in an inverted "L" shape. A second electric telescopic rod 52 is fixedly installed on the inner side of the top of the support frame 51. The piston end of the second electric telescopic rod 52 is fixedly connected to a mounting frame 53. A motor 54 is fixedly installed in the inner cavity of the mounting frame 53. The output end of the motor 54 is fixedly connected to a rotating shaft through a coupling. The right side of the rotating shaft penetrates through the mounting frame 53 and extends to the right. A cutting blade 55 is fixedly installed at the extended end of the rotating shaft. By starting the second electric telescopic rod 52 to drive the mounting frame 53, the motor 54, and the cutting blade 55 to move downward, and at the same time starting the motor 54 to drive the rotating shaft to rotate, the rotating shaft drives the cutting blade 55 to rotate to perform a cutting operation on the tire.

[0023] Working principle: After placing the tire on the workbench 3, start the first electric telescopic rod 48 to drive the rack 49 to move. The rack 49 drives the adjusting gear 47 to rotate, and the adjusting gear 47 drives the second rotating rod 45 to rotate. Thus, the second rotating rod 45 drives the push plate 46 to rotate and push against the fixed block 44. Thereby, the fixed block 44 drives the slider 42 to slide along the inner wall of the chute 41 and stretch the spring 43. Thus, the two fixed blocks 44 move away from each other and tightly fix the tire. And the push plate 46 is set to be oval. When the push plate 46 rotates, the spring 43 contracts by its own elastic force and drives the slider 42 to move. The slider 42 drives the fixed block 44 to move. Thereby, the distance between the two fixed blocks 44 can be adjusted according to the size of the tire, facilitating the fixation of tires of different sizes.

[0024] Please refer to Figures 1-4 , on the basis of the above embodiment, in another embodiment of the present utility model, the bottom end of the first rotating rod 2 extends into the interior of the base 1. A rotating mechanism 6 is provided on the base 1. The rotating mechanism 6 includes: a first bevel gear 61, which is fixedly connected to the bottom end of the first rotating rod 2. It further includes: a third rotating rod 62, which is rotatably connected to the front inner wall of the base 1 through a bearing. A second bevel gear 63 is fixedly connected to the rear end of the third rotating rod 62. The front end of the third rotating rod 62 penetrates through the base 1 and extends forward. A handwheel 64 is fixedly connected to the extending end of the third rotating rod 62. The second bevel gear 63 meshes with the first bevel gear 61. Support legs 7 are respectively and fixedly connected to the four corners of the bottom of the base 1. When rotating the handwheel 64, the handwheel 64 drives the third rotating rod 62 and the second bevel gear 63 to rotate, thereby driving the first bevel gear 61 to rotate. Thus, the first bevel gear 61 drives the first rotating rod 2 and the workbench 3 to rotate, thereby driving the fixed tire to rotate, facilitating the cutting operation on different parts of the tire and improving the practicability.

[0025] Working principle: Rotate the handwheel 64 to drive the third rotating rod 62 to rotate. The third rotating rod 62 drives the second bevel gear 63 to rotate. The second bevel gear 63 drives the first bevel gear 61 to rotate. Thus, the first bevel gear 61 drives the first rotating rod 2 to rotate. The first rotating rod 2 drives the workbench 3 to rotate, thereby driving the tire fixed on the workbench 3 to rotate, facilitating the cutting operation on different parts of the tire.

[0026] It should be noted that, for the convenience of control, control switches for controlling opening and closing are provided on the first electric telescopic rod 48, the second electric telescopic rod 52, and the motor 54 in the above embodiments.
