It is mainly used to withstand various tensions generated during the operation of the conveyor belt, preventing excessive stretching or breakage. It provides stable structural support for the conveyor belt, keeping it in good shape and operating condition. At the same time, it can also enhance the conveyor belt's impact and wear resistance, extending its overall service life. Common conveyor belt core materials include cotton canvas, nylon canvas, polyester canvas, and other types. Different core materials are suitable for different working environments and conveying needs. For example, some are suitable for light-duty conveying scenarios, while others are suitable for heavy-duty, high-strength conveying applications. In the production and application of conveyor belts, the selection of the core has a significant impact on the performance and effectiveness of the conveyor belt.

[0003] In the production process of rubber conveyor belt cores, the installation and fixation of the unwinding shaft is crucial. Traditional unwinding methods are prone to problems such as unstable unwinding shafts, which can cause swaying and deviation due to the tension of the belt blank during unwinding, resulting in unstable belt blank transportation and affecting the subsequent calendering and molding quality. Alternatively, the installation and disassembly process is cumbersome, requiring multiple tools, consuming a lot of manpower and time, and reducing production efficiency. Conventional limiting methods have poor adaptability to different specifications of unwinding shafts, making it difficult to meet diverse production needs. Therefore, a new type of rapid forming device for rubber conveyor belt cores is needed. Utility Model Content

[0021] Please see Figure 1-5 This utility model provides a technical solution: a novel rapid forming device for rubber conveyor belt cores, wherein: The device base 1 provides stable support for the entire device, and the first side plate 2 is fixedly connected to the top of the device base 1, serving as the mounting base for the unwinding shaft limiting assembly.

[0022] The detachable rotating shaft 10 is rotatably connected to the surface of the first side plate 2, and the unwinding shaft 11 is fixedly sleeved on the outer surface of the detachable rotating shaft 10 for mounting the blank roll.

[0023] The slide groove 12 is formed on the surface of the first side plate 2. The retaining plate 13 is slidably connected to the inside of the first side plate 2. The threaded rod 14 is rotatably connected to the inside of the first side plate 2. The retaining plate 13 is threadedly sleeved on the outer surface of the threaded rod 14. The knob 15 is rotatably connected to the surface of the first side plate 2 and fixedly connected to the threaded rod 14. Rotating the knob 15 can drive the threaded rod 14 to rotate, so that the retaining plate 13 slides along the slide groove 12.

[0024] The clamping plate 13 contacts the detachable rotating shaft 10, and its surface is provided with an arc-shaped groove adapted to the detachable rotating shaft 10. The surface of the first side plate 2 is provided with a slot for installing the detachable rotating shaft 10. The unwinding shaft 11 is fixed by clamping the detachable rotating shaft 10 with the clamping plate 13, making installation and disassembly convenient.

[0025] Multiple fans A16 are fixedly connected at equal intervals to the top of the first side plate 2, and multiple fans B17 are fixedly connected to the top of the device base 1. The unwinding shaft 11 is located between the fans A16 and the fans B17, which can preheat or cool the strip blank at the unwinding shaft 11 to improve the subsequent processing effect.

[0026] A third side plate 4 is fixedly connected to the top of the device base 1. A motor 18 is fixedly connected to the surface of the third side plate 4. A bidirectional screw 19 is fixedly connected to the output end of the motor 18. The bidirectional screw 19 is rotatably connected to the third side plate 4. The motor 18 provides power for the rotation of the bidirectional screw 19.

[0027] A slider 20 is threaded onto the outer surface of the bidirectional screw 19. The slider 20 is slidably connected to the top of the device base 1. A bracket 21 is fixedly connected to the top of the slider 20. A guide roller 22 is rotatably connected to the surface of the bracket 21. The rotation of the bidirectional screw 19 drives the slider 20 to move, thereby adjusting the position of the guide roller 22 through the bracket 21 to limit the deviation on both sides of the blank.

[0028] A second side plate 3 is fixedly connected to the top of the device base 1, and a hydraulic cylinder 8 is fixedly connected to the top of the second side plate 3. A lifting bracket 7 is fixedly connected to the output end of the hydraulic cylinder 8. The lifting bracket 7 is slidably connected to the second side plate 3, and the hydraulic cylinder 8 can push the lifting bracket 7 to slide to adjust its position.

[0029] The surfaces of the second side plate 3 and the lifting bracket 7 are rotatably connected with pressure rollers 23. The distance between the lifting bracket 7 and the pressure rollers 23 on the surface of the second side plate 3 can be adjusted by the hydraulic cylinder 8 to accommodate strip blanks of different thicknesses. The strip blanks are guided by the guide rollers 22 and then rolled into shape by the pressure rollers 23.

[0030] Two pressure roller protection components 9 are slidably connected to the outer surface of the pressure roller 23. The two pressure roller protection components 9 are fixedly connected by bolts. The pressure roller protection components 9 can be smooth pressure roller sleeves or patterned pressure roller sleeves, which can protect the pressure roller and realize the surface texture processing of the blank, and have a wide range of applications.

[0031] The top of the device base 1 is fixedly connected to a fourth side plate 5, and a winding roller 6 is rotatably connected to the surface of the fourth side plate 5, which is used to wind up the strip blank after calendering to complete the entire strip core forming process.

[0032] Working principle: The strip is wound onto the unwinding shaft 11. First, the knob 15 on the surface of the first side plate 2 is rotated to drive the threaded rod 14 to rotate, causing the clamping plate 13 to slide along the slide groove 12. After the clamping plate 13 is opened, the detachable rotating shaft 10 is installed in the slot of the first side plate 2. The knob 15 is rotated in the opposite direction to allow the clamping plate 13 to clamp the detachable rotating shaft 10 through the arc groove, thus fixing the unwinding shaft 11. The motor 18 drives the bidirectional screw 19 to move the slider 20, and the guide roller 22, whose position is adjusted by the bracket 21, limits the two sides of the strip to prevent deviation. The strip extends to the second side. At the pressure roller 23 on the side of plate 3, the hydraulic cylinder 8 at the top of the second side plate 3 is activated to push the lifting bracket 7 to slide, and the distance between the lifting bracket 7 and the pressure roller 23 on the surface of the second side plate 3 is adjusted to match the thickness of the strip blank. The fan A16 at the top of the first side plate 2 and the fan B17 at the top of the device base 1 preheat or cool the strip blank at the unwinding shaft 11. After being guided by the guide roller 22, the strip blank is calendered by the pressure roller 23. The formed strip blank is wound up by the winding roller 6. The two pressure roller protection components 9 on the outer surface of the pressure roller 23 are fixed by bolts to realize pressure roller protection or strip blank surface texture processing.

[0033] Example 1: (Reference) Figure 1 ) The pressure roller protection component 9 can be a smooth pressure roller sleeve. Two smooth pressure roller protection components 9 are fixed to the outer surface of the pressure roller 23 by bolts. After the strip blank is guided by the guide roller 22, it enters between the pressure rollers 23. The smooth pressure roller sleeve contacts the surface of the strip blank. During the calendering process, it will not change the original surface state of the strip blank. It can effectively prevent the pressure roller 23 from directly contacting the strip blank and causing scratches, thus protecting the surface of the strip blank. At the same time, it ensures that the surface of the strip blank is flat and smooth, improving the appearance quality of the product. It is suitable for the production of rubber conveyor belt cores with high requirements for surface smoothness.

[0034] Example 2: (Reference) Figure 2 ) Replace the pressure roller protection component 9 with a patterned pressure roller sleeve, which is also fixed to the outer surface of the pressure roller 23 with bolts. When the belt passes through the pressure roller 23, the patterned pressure roller sleeve will press a preset pattern on the surface of the belt, increasing the friction of the belt surface and meeting the needs of conveyor belt use in specific scenarios. No additional pattern processing steps are required, simplifying the production process. Moreover, the patterned pressure roller sleeve is easy to replace, and different pattern styles can be changed as needed, improving the versatility and flexibility of the device.

[0035] Example 3: (Reference) Figure 1-5 ) When producing rubber conveyor belt cores for food transportation, a smooth pressure roller sleeve is selected as the pressure roller protection component 9. This ensures that the surface of the belt blank is smooth and free of impurities, meets food hygiene standards, and guarantees the safety of the food transportation process.

[0036] When producing rubber conveyor belt cores for conveying mining materials, the pressure roller protection component 9 is replaced with a patterned pressure roller sleeve, which forms an anti-slip pattern on the surface of the belt blank, enhances the friction between the conveyor belt and the material, prevents the material from slipping during the conveying process, and improves the conveying efficiency and stability.

[0037] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
