From "waste" to "rebirth" tire vulcanizer with smart wings

Into the vulcanization workshop of Shandong Qilun Rubber Co., LTD., a subsidiary of Shandong Huasheng Rubber Group, the heat wave immediately came. In the production line, a strip of raw tires are loaded into the vulcanization machine, and the pattern is heated in the mold after the appropriate time and suitable conditions, and it becomes a finished tire after the setting. "The production of tires needs to go through many processes, and vulcanization is an indispensable part of the production of tires. The vulcanization process is actually similar to the "steamed bun". "Before they are cooked, they are raw and inedible, but after steaming in a steamer, they become delicious." Shandong Qilun rubber Co., Ltd. vulcanization workshop director Deng Yuxiang figuratively said.

In the middle of the many mechanical vulcanizing machines lined up, there is a "new" vulcanizing machine that looks a little "different", this "new" vulcanizing machine is not only more beautiful in appearance, low noise, but also more intelligent in operation. The worker's master Shi Yungang is simultaneously operating the "new" vulcanizing machine and the eleven mechanical vulcanizing machines beside it. The reporter noted that Shi Yungang only needs to scan the code setting on the "new" vulcanization machine, and the birth tire is automatically loaded into the vulcanization machine through the manipulator, and the pressure, temperature, time and other data are displayed on the equipment screen in real time, and the workers no longer need to operate other procedures; The other mechanical vulcanization machine requires manual loading and unloading of tires, "push" "support" "pressure" medium series of operations; Especially when the mold is alternating, the tensile height of the capsule needs to be replaced to complete the styling sleeve, and the labor intensity is very different. "This' new 'vulcanizing machine is called dual power intelligent vulcanizing machine, was put into use in November last year, the use of the process, obviously feel to reduce the labor intensity of workers, improve production efficiency and accuracy, and achieve energy saving and consumption reduction." Workshop director Deng Yuxiang introduced.

The dual-power intelligent vulcanizing machine was developed by Guorao Rubber Industry Research Institute of Qingdao University of Science and Technology, and was put into use in the vulcanizing workshop of Shandong Qilun Rubber Co., LTD., in November 2020, and its "predecessor" was a traditional mechanical vulcanizing machine. After a period of comparative use, it was found that the daily output of the modified dual-power intelligent vulcanizer was 8% higher than that of the traditional mechanical vulcanizer, and the shaping accuracy was more accurate, so as to reduce the scrap rate and improve product quality. At the same time, the mechanical vulcanization machine can operate a maximum of about 10 units, and the intelligent machine can operate 15 units at the same time, and the efficient working efficiency is undoubtedly a major breakthrough for the rubber tire industry. In December last year, Shandong Huasheng Rubber Group issued relevant documents, planning to transform 61 vulcanizing machines in its companies, and the first batch of 14 vulcanizing machines are currently being transformed, which greatly reduces the input cost of enterprises.

Guangrao Rubber Industry Research Institute of Qingdao University of Science and Technology is a new research and development institution jointly established by Qingdao University of Science and Technology and Guangrao County government. It was put into operation in November 2019. "In the process of investigation of rubber tire enterprises in Guangrao County, it was found that most of the vulcanizing machines of enterprises are traditional mechanical vulcanizing machines introduced around 2003, and after more than ten years of use, they have now entered the years of overhaul or scrap." But the mechanical components of these vulcanizers are very strong and have good precision, and how to deal with these old mechanical vulcanizers has become a common problem in the rubber industry of Guangrao County." Lin Guangyi, the leader of research and development of dual-power intelligent vulcanizing machine and president of Guangrao Rubber Industry Research Institute of Qingdao University of Science and Technology, said. "Using the original mechanical mechanism of the mechanical vulcanization machine, introducing advanced hydraulic control, electrical control, automatic control and intelligent control system, so that the entire old equipment is upgraded into an intelligent vulcanization machine" has become the research and development topic of Lin Guangyi and his team. In order to successfully promote the project in the industry, Qingdao University of Science and Technology Guangrao Rubber Industry Research Institute and Shandong Huasheng Rubber Group signed an agreement to upgrade a traditional mechanical vulcanization machine for the enterprise free of charge.

"In March 2020, after the docking of the two sides was completed, we invested in the research and development process, the basic transformation was completed in July, and after two months of data collection, the expected effect was fully achieved." Lin Guangyi introduced that in the process of research and development, due to the use of hydraulic power in the center of the dual-power intelligent vulcanization machine, the problem of dual-power coordination was encountered in the process of dual-power compatibility. Perseverance wears away the stone. Through numerous data operations and the use of virtual prototyping technology for high-frequency complex simulation, the R & D team completed the optimal design of dual-power coordination in the fastest time and at the lowest cost, ensuring the high reliability of the product, and the temperature difference was controlled from the old 10℃ to about 5℃. The "dual power intelligent vulcanizing machine" renovation project has reached the international advanced level after identification.

In the tide of the transformation and upgrading of the rubber tire industry cluster, the county aims at the industry's cutting-edge technology and high-end products, the implementation of innovation-driven strategy, and the promotion of the main position of innovation and independent innovation ability of enterprises. Vigorously promote enterprise scientific and technological innovation, increase investment in "soft" and "hard" facilities, strengthen docking with top universities and research institutes in the field, and establish a platform for industry-university-research cooperation; Increase the introduction of talents, build their own high-level R & D team; Strengthen the construction of scientific research platforms, purchase advanced research and development equipment, and build a number of provincial and above enterprise technology centers and engineering centers. Among them, Qingdao University of Science and Technology Guangrao Rubber Industry Research Institute focuses on the construction of "4 centers +2 platforms", rubber new material research and development center, rubber intelligent equipment research and development center, waste rubber high-value recycling research and development center, rubber factory environmental assessment and inspection research and development center and rubber industry public testing service platform, rubber factory environmental testing and evaluation service platform, Strive to realize the transformation of scientific research achievements and promote the transformation of old and new kinetic energy in the rubber tire industry.
