Description

Technical Field

[0001] The invention relates to the technical field of rubber production and processing, in particular to a rubber mould for producing conveyor belts. Background Art

[0002] As an important transmission equipment in the field of industrial automation and logistics transportation, the quality and performance of conveyor belts are directly related to production efficiency, safety and cost-effectiveness. Rubber conveyor belts are widely used in mines, ports, factories and other occasions due to their excellent wear resistance, tear resistance and adaptability.

[0003] After searching, the Chinese patent number CN115772298A discloses that the invention provides a rubber mold for producing patterned conveyor belts, characterized in that the material formula of the rubber mold is as follows by weight: 60 to 70 parts of EPDM rubber, 10-20 parts of EPDM rubber, 30 to 45 parts of reinforcing agent, 10 to 15 parts of zinc oxide, 5 to 10 parts of erucamide, 2 to 3 parts of oleamide, 10 to 15 parts of softener, 1 to 5 parts of antioxidant, 1 to 5 parts of stearic acid, 2 to 7 parts of vulcanizing agent DCP, 1 to 5 parts of cross-linking agent TAIC, and 1 to 5 parts of polytetrafluoroethylene powder. The rubber mold of the invention for producing patterned conveyor belts has mechanical properties such as hardness and strength that meet the production requirements of patterned conveyor belts and has excellent heat resistance. It is used to replace traditional iron molds, which greatly reduces the weight of the mold and makes it easy to operate. It can improve the production efficiency of patterned conveyor belts and reduce the manufacturing cost of patterned conveyor belts. In addition, it is not easy for mold sticking to occur during the production of patterned conveyor belts, and the surface quality of the produced conveyor belt products is good.

[0004] However, the existing rubber molds for producing conveyor belts need to produce conveyor belts of different widths according to different requirements when producing rubber conveyor belts, and the rubber molds of the conveyor belts lack the function of automatic adjustment. Therefore, when adjusting the width of the conveyor belt, manual operation or fixed molds are usually relied on, resulting in low adjustment accuracy and poor flexibility. At the same time, the molds need to be frequently replaced when producing conveyor belts of different specifications, thereby increasing the equipment replacement cost and production time. Based on this, the present invention designs a rubber mold for producing conveyor belts to solve the above problems. Summary of the invention

The lifting assembly includes a connecting base plate 20 installed on the top of the mixing barrel 16, a supporting plate 21 is installed on the top of the connecting base plate 20, a connecting top plate is arranged on the top of the supporting plate 21, two groups of support plates 21 are arranged and are symmetrically distributed, a second dual-axis motor 22 is installed on one side of the supporting plate 21 on the left, a first rotating rod 23 is installed on the output shaft on one side of the second dual-axis motor 22, a second rotating rod 24 is installed between the supporting plates 21, a passive rod 25 is installed on one side of the second rotating rod 24, a connecting rod 26 is installed on the output shaft on the other side of the second dual-axis motor 22, a rotating belt 27 is installed on the outer ring of the passive rod 25 and the connecting rod 26, a cam 28 is installed on the outer ring of the first rotating rod 23 and the second rotating rod 24, a sliding groove 29 is opened at the bottom of the connecting top plate, the cam 28 slides in the inner cavity of the sliding groove 29, and a telescopic assembly is installed between the support plate 21 and the connecting top plate.

[0044] The telescopic assembly includes a second telescopic rod 30 installed on the top of the support plate 21, the top of the second telescopic rod 30 is connected to the bottom of the connecting top plate, and the second telescopic rod 30 is provided in four groups and distributed in a rectangular array.

[0045] The working principle of the embodiment of the present invention is as follows: the mixing barrel 16 is used as a container for the mixed material and is connected to the material storage box 2 through the connecting pipe 17. During the mixing process, the second dual-axis motor 22 is started to drive the first rotating rod 23 and the second rotating rod 24 to rotate at different speeds. This differential rotation causes the two groups of cams 28 to generate elliptical trajectory motion in the slide groove 29 connected to the top plate, thereby driving the top plate connected and the mixing assembly thereon to vibrate up and down. This vibration is combined with the rotation of the mixing rod 32 and the mixing plate 33 driven by the rotating motor 31 to form a composite mixing effect.

After vulcanization, it is cooled to below 50°C through the conveyor belt 1 and cut into finished products.

[0049] The working principle of the embodiment of the present invention is: various raw materials are added to the mixing barrel 16 according to the formula ratio, and stirred and mixed by the rotating motor 31. After a period of stirring, additives such as vulcanizing agent DCP, auxiliary cross-linking agent TAIC and polytetrafluoroethylene powder are added, and stirring is continued until the materials are completely dispersed and uniform, and then the mixed materials are input into the storage box 2 through the connecting pipe 17, and the strip embryo is formed by the extrusion action of the electric push rod 4 and the extrusion plate 5. In this process, the adjustment component adjusts the width of the conveyor belt according to production requirements, and finally the strip embryo enters the vulcanization box for dynamic vulcanization treatment.

Subsequently, the mixed material is fed into the storage box 2, and the material is extruded into a strip-shaped embryo through the support and parallelism correction of the extrusion plate 5 driven by the electric push rod 4 and the first telescopic rod 6. At the same time, the first dual-axis motor 10 in the adjustment component drives the unidirectional screw 11 to adjust the width of the conveyor belt according to production requirements.
