BRIEF DESCRIPTION OF THE DRAWINGS

[0028] Figure 1 This is a flow chart of the method mentioned in Example 1 of the present invention. DETAILED DESCRIPTION

[0029] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0030] The present invention solves the problem of easy breaking of the transmission belt by integrally casting the rubber top surface, the base layer and the rubber bottom surface in sequence, and prevents sliding between the rubber surface and the base belt through the microfiber textile layer, and optimizes and improves the structure, performance and durability of the transmission belt through the tempered wire; based on the low temperature treatment method, the transmission belt is prevented from shrinking and the yarn slipping; the transmission belt is prevented from stretching after long-term use through high temperature protection treatment; a mold is also set to uniformly press the transmission belt, and a canvas layer is placed on top to ensure the smooth operation of the transmission belt, prevent the yarn from jumping during operation, and improve the cloth surface quality. Specifically include the following contents.

[0031] Embodiment 1:

[0032] See also Figure 1 The present invention provides a special microfiber transmission belt and a preparation method thereof, comprising:

[0033] S1: Process the rotating metal skeleton and the corresponding microfiber textile layer according to the size of the transmission belt; the details are as follows:

[0034] Building a rotating metal skeleton and two corresponding microfiber textile layers based on the size of the transmission belt to be processed can ensure that the transmission belt can fit the transmission equipment and ensure the normal operation of the transmission belt.

[0035] S2: putting the rubber polymer material into a mixer and mixing it until the materials are evenly mixed to obtain a rubber casting raw material and a nylon sheet base raw material;

[0036] S3: pouring the casting raw material into a rotating metal mold to obtain a rubber bottom surface, and then placing a microfiber textile layer;

[0037] The rubber bottom surface is poured into a rotating metal mold, and then the microfiber textile layer is placed; the microfiber textile layer can enhance the strength and wear resistance of the transmission belt, improve the stability and precision of the transmission belt, reduce the transmission error, and ensure the normal operation of the transmission system; at the same time, because the microfiber textile layer has a lower internal friction coefficient, the friction loss of the transmission belt is small during operation, which can reduce energy loss and improve transmission efficiency. The microfiber textile layer also has high strength and excellent tensile resistance, which can make the transmission belt not easy to deform or break when subjected to tension, ensuring the reliability of the transmission system. The microfiber textile material also has good high temperature resistance and can maintain stable performance in high temperature environments, which is suitable for transmission needs under some special working conditions.

[0038] S4: pouring a nylon base layer raw material onto the microfiber textile layer to obtain a nylon base layer for the base layer, evenly laying the tempered wire on the nylon base layer for the base layer, pouring the remaining nylon base layer raw material onto the tempered wire to obtain a complete nylon base layer, and finally pouring a rubber raw material on the nylon base layer to obtain a rubber top surface;

[0039] The nylon base layer is poured onto the microfiber textile layer, and then the tempered wire is evenly laid on the nylon base layer. Then the remaining nylon base material is poured onto the tempered wire to obtain a complete nylon base layer, and finally the rubber top surface is poured on the nylon base layer; this can ensure a stable connection between the nylon base layer and the rubber bottom surface. By setting the tempered wire in the middle nylon base layer, the tempered wire can be used as a reinforcing material, which can effectively increase the tensile strength and load-bearing capacity of the transmission belt; the hardness and strength of the tempered wire can effectively improve the wear resistance of the transmission belt and extend its service life; setting the tempered wire in the nylon base layer can maintain the softness and bendability of the transmission belt, which is beneficial to the operation of the transmission belt and adaptability to various working conditions. The application of tempered wire in the transmission belt can achieve optimization and improvement of the structure, performance and durability of the transmission belt. Such a design can ensure that the transmission belt has better stability and reliability in various industrial application scenarios.

[0040] During the pouring process from S3 to S4, the metal skeleton is kept in a continuous rotation state by rotating 50,000 times, so that the gas in the mold can be discharged smoothly, thereby obtaining a sound casting. When the mold rotates, the flow state of the molten rubber liquid in the casting changes greatly due to the effect of gravity. The specific pouring thickness can be controlled by the amount of poured rubber liquid. The casting prepared by the integrated pouring method has uniform thickness, smooth interface and no bubbles, and can be used to prepare low-loss special microfiber transmission belts.

[0041] S5: Take out the solidified casting body and place the casting body in a low temperature treatment device at -60°C for a certain period of time; the details are as follows:

[0042] The casting body is treated at -60℃ low temperature, which can make it have the characteristics of low resistance and anti-shrinkage. This allows the transmission belt to provide good grip in extremely cold environments. At the same time, it is not easily affected by temperature and shrinks. It can be used in cold areas and provide good safety protection.

[0043] S6: placing the low temperature treated casting body in a heating device at 150°C for a certain period of time; the details are as follows:

[0044] High temperature treatment of rubber at 150°C can prevent the special microfiber transmission belt from elongating and ensure the stability of the transmission belt.

[0045] S7: uniformly pressing and molding the high temperature treated casting body to obtain a ring-shaped jointless special microfiber transmission belt; the details are as follows:

[0046] The transmission belt obtained by a unified one-time pressing method through the mold can have a higher flatness, which can improve the smoothness of the operation of the two-for-one twister, ensure that the operating tolerance does not exceed plus or minus 1 wire, that is, 0.01 mm, prevent the two-for-one twister from jumping, and improve the quality of the textile fabric.

[0047] S8: A canvas layer is provided on the outer surface of the rubber top surface of the transmission belt; specifically as follows:

[0048] A ring-shaped seamless wear-resistant textile fabric divided into several colors can also be placed on the rubber top surface of the pressed and formed ring-shaped seamless special microfiber transmission belt. The rubber surface can be coated with multiple colors. If only a small amount of color is coated, light green can be used as the base color and golden stripes can be used to distinguish them. The rubber top surface can also be divided into seven equal parts, each corresponding to a color, and every two colors can be distinguished by golden stripes to ensure the beauty of the transmission belt.

[0049] S9: Cut, trim and inspect the transmission belt according to the preset size. Details are as follows:

[0050] Cutting the transmission belt according to the size of the transmission equipment can preserve the fit between the transmission belt and the transmission equipment and ensure the stable twisting of the yarn. During the yarn twisting process, two or more strands of yarn are laid flat on the special microfiber transmission belt, and short, medium and long segments are obtained by twisting based on the required twist. The special microfiber transmission belt can evenly extend it, making the fabric feel smoother, silkier and softer.

[0051] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
