[0028] The detection control mechanism includes a moving frame 8, which is horizontally arranged above the base 1. The moving frame 8 is parallel to the conveying roller 3. A pressure sensor 19 is installed on the top of the moving frame 8. A fixed plate 20 is installed at the detection end of the pressure sensor 19. A plurality of springs 22 are installed at one end of the fixed plate 20 away from the pressure sensor 19. A moving plate 21 is installed at one end of the spring 22 away from the fixed plate 20. A plurality of slide bars 16 are installed at one end of the moving plate 21 away from the fixed plate 20. A mounting frame 15 is horizontally installed at the lower end of the slide bar 16 through the moving frame 8. The slide bar 16 is slidably connected to the moving frame 8. A rotating roller 14 for facilitating tire tread transportation is horizontally arranged inside the mounting frame 15. Both ends of the rotating roller 14 are rotatably connected to the inner wall of the mounting frame 15. A controller 10 for receiving data information of the pressure sensor 19 and controlling the rotation speed of the conveying roller 3 on the rear linkage line bracket 9 is installed at the bottom of the rear linkage line bracket 9. Lifting components for lifting the moving frame 8 are arranged at both ends of the moving frame 8.

[0029] When in use, the tire tread passes through the conveying roller 3 on the front linkage line bracket 2, the lower end of the rotating roller 14 and the conveying roller 3 on the rear linkage line bracket 9 in sequence, and the tire tread squeezes and pushes the rotating roller 14, so that the pressure sensor 19 generates an initial pressure value.

[0030] When the conveying speed of the tire tread by the conveying roller 3 on the rear linkage line bracket 9 is greater than the conveying speed of the tire tread by the conveying roller 3 on the front linkage line bracket 2, the tire tread between the front linkage line bracket 2 and the rear linkage line bracket 9 is tightened, the tire tread squeezes and pushes the rotating roller 14, the rotating roller 14 pushes the mounting frame 15 to move, the mounting frame 15 pushes the slide bar 16 to move, the slide bar 16 pushes the movable plate 21 to move, the movable plate 21 compresses the spring 22, the spring 22 squeezes the fixed plate 20, the fixed plate 20 squeezes the detection end of the pressure sensor 19, so that the pressure value detected by the pressure sensor 19 becomes larger, the pressure sensor 19 transmits the detected pressure value to the controller 10, the controller 10 controls the power motor of the conveying roller 3 on the rear linkage line bracket 9, reduces the conveying speed of the tire tread, until the pressure value detected by the pressure sensor 19 remains stable, that is, the conveying speed of the tire tread by the conveying roller 3 on the front linkage line bracket 2 is equal to the conveying speed of the tire tread by the conveying roller 3 on the rear linkage line bracket 9.

[0031] When the conveying speed of the tire tread by the conveying roller 3 on the rear linkage line bracket 9 is lower than the conveying speed of the tire tread by the conveying roller 3 on the front linkage line bracket 2, the tire tread between the front linkage line bracket 2 and the rear linkage line bracket 9 becomes loose, and the tire tread moves downward. Under the action of gravity and the elastic force of the spring 22, the rotating roller 14, the mounting frame 15, the sliding rod 16, and the movable plate 21 move downward, so that the pressure value detected by the pressure sensor 19 becomes smaller. The pressure sensor 19 transmits the detected pressure value to the controller 10. The controller 10 controls the power motor of the conveying roller 3 on the rear linkage line bracket 9 to increase the conveying speed of the tire tread until the pressure value detected by the pressure sensor 19 remains stable, that is, the conveying speed of the tire tread by the conveying roller 3 on the front linkage line bracket 2 is equal to the conveying speed of the tire tread by the conveying roller 3 on the rear linkage line bracket 9.

[0032] The lifting assembly includes two fixed frames 11, which are vertically mounted on the upper ends of the base 1 at both ends of the moving frame 8. A motor 13 is mounted on the bottom of the fixed frame 11, and a rotating shaft 12 is mounted on the output end of the motor 13. The upper end of the rotating shaft 12 is rotatably connected to the top of the fixed frame 11. A screw 18 is mounted on the side wall of the rotating shaft 12. A moving block 17 is rotatably connected to the side wall of the screw 18 through a thread. The moving block 17 moves along the inner wall of the fixed frame 11. The two moving blocks 17 are on the same horizontal plane, and one end of the moving block 17 close to the moving frame 8 is mounted on the side wall of the moving frame 8.

[0033] After the conveying roller 3 on the rear linkage line bracket 9 has completed the adjustment of the tire tread conveying speed, the motor 13 is started, the output end of the motor 13 drives the rotating shaft 12 to rotate, the rotating shaft 12 drives the screw 18 to rotate, under the action of the thread, the screw 18 drives the moving block 17 to move up and down, the moving block 17 drives the moving frame 8 to move up and down, so that the pressure value detected by the pressure sensor 19 is restored to the initial value.

[0034] The limiting mechanism includes two mutually parallel mounting rods 4, and the two mounting rods 4 are horizontally arranged below the conveying roller 3. The mounting rods 4 and the conveying roller 3 are perpendicular to each other. A plurality of fixing rods 6 are vertically installed on the upper ends of the mounting rods 4. A rotating cylinder 7 for facilitating tire tread transportation is rotatably connected to the side walls of the fixing rods 6. The fixing rods 6 are arranged between two adjacent conveying rollers 3. Electric telescopic rods 5 for driving the mounting rods 4 to move are horizontally installed on the side walls of the two mounting rods 4 that are away from each other. The electric telescopic rods 5 are installed on the side walls of the rear linkage line bracket 9 and the front linkage line bracket 2.

[0035] When in use, the electric telescopic rod 5 is started according to the width of the tire tread, and the output end of the electric telescopic rod 5 drives the mounting rod 4 to move, the mounting rod 4 drives the fixing rod 6 to move, and the fixing rod 6 drives the rotating cylinder 7 to move, so that the rotating cylinders 7 on the two mounting rods 4 limit the tire tread on the conveying roller 3.

[0036] Working principle of a front and rear linkage line speed adjustment device for tire production:

[0037] When in use, the electric telescopic rod 5 is started according to the width of the tire tread, and the output end of the electric telescopic rod 5 drives the mounting rod 4 to move, the mounting rod 4 drives the fixing rod 6 to move, and the fixing rod 6 drives the rotating cylinder 7 to move, so that the rotating cylinders 7 on the two mounting rods 4 limit the tire tread on the conveying roller 3.

[0038] The tire tread passes through the conveying roller 3 on the front linkage line support 2, the lower end of the rotating roller 14 and the conveying roller 3 on the rear linkage line support 9 in sequence, and the tire tread squeezes and pushes the rotating roller 14, so that the pressure sensor 19 generates an initial pressure value.

[0039] When the conveying speed of the tire tread by the conveying roller 3 on the rear linkage line bracket 9 is greater than the conveying speed of the tire tread by the conveying roller 3 on the front linkage line bracket 2, the tire tread between the front linkage line bracket 2 and the rear linkage line bracket 9 is tightened, the tire tread squeezes and pushes the rotating roller 14, the rotating roller 14 pushes the mounting frame 15 to move, the mounting frame 15 pushes the slide bar 16 to move, the slide bar 16 pushes the movable plate 21 to move, the movable plate 21 compresses the spring 22, the spring 22 squeezes the fixed plate 20, the fixed plate 20 squeezes the detection end of the pressure sensor 19, so that the pressure value detected by the pressure sensor 19 becomes larger, the pressure sensor 19 transmits the detected pressure value to the controller 10, the controller 10 controls the power motor of the conveying roller 3 on the rear linkage line bracket 9, reduces the conveying speed of the tire tread, until the pressure value detected by the pressure sensor 19 remains stable, that is, the conveying speed of the tire tread by the conveying roller 3 on the front linkage line bracket 2 is equal to the conveying speed of the tire tread by the conveying roller 3 on the rear linkage line bracket 9.

[0040] After the adjustment is completed, the motor 13 is started, and the output end of the motor 13 drives the rotating shaft 12 to rotate, and the rotating shaft 12 drives the screw 18 to rotate. Under the action of the thread, the screw 18 drives the moving block 17 to move upward, and the moving block 17 drives the moving frame 8 to move upward, so that the pressure value detected by the pressure sensor 19 is restored to the initial value.

[0041] When the conveying speed of the tire tread by the conveying roller 3 on the rear linkage line bracket 9 is lower than the conveying speed of the tire tread by the conveying roller 3 on the front linkage line bracket 2, the tire tread between the front linkage line bracket 2 and the rear linkage line bracket 9 becomes loose, and the tire tread moves downward. Under the action of gravity and the elastic force of the spring 22, the rotating roller 14, the mounting frame 15, the sliding rod 16, and the movable plate 21 move downward, so that the pressure value detected by the pressure sensor 19 becomes smaller. The pressure sensor 19 transmits the detected pressure value to the controller 10. The controller 10 controls the power motor of the conveying roller 3 on the rear linkage line bracket 9 to increase the conveying speed of the tire tread until the pressure value detected by the pressure sensor 19 remains stable, that is, the conveying speed of the tire tread by the conveying roller 3 on the front linkage line bracket 2 is equal to the conveying speed of the tire tread by the conveying roller 3 on the rear linkage line bracket 9.

[0042] After the adjustment is completed, the motor 13 is started, and the output end of the motor 13 drives the rotating shaft 12 to rotate, and the rotating shaft 12 drives the screw 18 to rotate. Under the action of the thread, the screw 18 drives the moving block 17 to move downward, and the moving block 17 drives the moving frame 8 to move downward, so that the pressure value detected by the pressure sensor 19 is restored to the initial value.

[0043] It is obvious to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments, and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention.
