Description

Technical Field

[0001] This utility model relates to the field of tire pad fabric cutting technology, and in particular to a tire pad fabric cutting device with adaptive guiding positioning. Background Technology

[0002] In the tire manufacturing process, tire pad fabric, as an important component of the reinforcing structure, is widely used in key parts such as the tire carcass ply and belt ply. It plays a role in enhancing tire strength, improving tensile performance, and maintaining tire shape stability. Its cutting precision is not only related to the smooth progress of subsequent laying and molding processes, but also directly affects the tire's structural uniformity, driving stability, and service life.

[0003] Currently, traditional tire pad fabric cutting equipment mostly adopts manual or semi-automatic operation, and generally lacks adaptive adjustment function for pad fabrics of different widths. This results in poor guiding and clamping effect, affecting cutting accuracy and production stability. In addition, most of these devices use fixed guiding structures, which cannot be adjusted synchronously according to the actual width of the pad fabric. This can easily lead to problems such as insecure clamping, material displacement, or even crushing.

[0028] like Figure 4 As shown, it also includes an electric slide rail 121 and a slider 122.

[0029] like Figure 1 , Figure 5 and Figure 6 As shown, it also includes a cutting plate 17, a first sliding plate 172, a stop plate 18, and a spring 19. The cutting plate 17 is installed on the top left side of the support frame 1. A cutting groove 171 is opened on the top left side of the cutting plate 17. The first sliding plate 172 is provided on the front side of the top of the cutting plate 17. The stop plate 18 is slidably connected to the top center of the cutting plate 17.

[0031] like Figure 1 , Figure 5 and Figure 7 As shown, it also includes a second sliding plate 251 and a loading box 26. A sliding groove 25 is provided on the top right side of the support frame 1. The sliding groove 25 is located below the front side of the first sliding plate 172. A second sliding plate 251 is provided on the lower right side of the support frame 1.

[0032] When using this device, firstly, place the tire pad fabric to be cut at the entrance between the first transmission roller 4 and the second transmission roller 5, ensuring it is flat and wrinkle-free to avoid deviation or jamming during transport. Then, connect the power supply, start the controller 27, and perform a no-load test on each actuator to ensure that the first motor 2, electric push rod 15, and electric slide rail 121 are functioning correctly. After confirming everything is in order, start the first motor 2. Its output shaft drives the first gear 3 to rotate, which in turn drives the second transmission roller 5 to rotate synchronously through the meshing second gear 6, thus smoothly feeding the tire pad fabric into the cutting area. Next, start the second motor 8, whose output shaft drives the first bevel gear... Wheel 9 rotates, driving the bidirectional screw 10 to operate synchronously via the second bevel gear 11 meshing with it. The sliding plate 12 moves inward or outward accordingly, automatically adapting the distance between the guide rollers 14 on both sides to the current width of the padding cloth, achieving initial clamping and positioning. The electric slide rail 121 can also be activated according to the thickness of the tire padding cloth, causing it to move the slider 122 up and down, thereby adjusting the height of the guide rollers 14, further improving clamping stability and achieving a more precise adaptive guiding function. When the tire padding cloth enters the cutting area, it is guided above the cutting plate 17. At this point, the handwheel 21 can be manually rotated according to the required cutting length, driving the screw 20 to rotate, thereby driving the second baffle 22 to move back and forth. The cutting length is precisely positioned using the ruler 24. Before cutting, the abutment plate 18 is in its natural state under the action of the spring 19. When the set length is reached, the controller 27 issues a command to activate the electric push rod 15. Its telescopic rod pushes the connecting plate 151 downward, causing the cutting blade 16 to vertically cut into the tire pad cloth. The cutting blade 16 presses against the abutment plate 18 while contacting the pad cloth, compressing the spring 19 to ensure stable and reliable cutting. After cutting, the cutting blade 16 returns to its original position, the spring 19 returns to its original state, and the abutment plate 18 returns to its original position, releasing the pad cloth. The cut tire pad cloth loses its support and falls from the cutting groove 171 under the action of gravity. Subsequently, it slides along the first sliding plate 172. The material slides into the material chute 25 and continues to slide down to the second material plate 251, finally falling into the loading box 26 for centralized collection. This achieves automatic separation and collection of finished products, improving work efficiency and reducing manual intervention. If the cutting size needs to be changed, the position of the second baffle 22 can be adjusted by rotating the handwheel 21 again, and the precise positioning can be made with reference to the ruler 24 to meet the production needs of different specifications of products. After use, turn off the power and stop the operation of the first motor 2, the second motor 8, the electric slide rail 121 and the electric push rod 15 in sequence. Clean up the residual materials, check the lubrication status of each moving part, and perform daily maintenance to extend the service life of the equipment and ensure the stability and safety of the next use.
