Present situation and Prospect of Wuxi belt Co., Ltd Wu Yizhen; transmission is mechanical transmission is an important transmission form, with the level of industrial technology and continuous improvement of machinery and equipment precision Huaqing quantization function and personalized requirements, and its increasingly wide range of applications, the transmission form is increasing. As a belt drive in the main parts of the transmission belt by original is vulnerable to a direction change, varieties and specifications to the diversity development, by the conventional package tape and ordinary flat with the development of the narrowband to broadband banded with a cutting edge with multi wedge belt synchronous belt rope core belt and film base flat belt and so on. These drives have been widely used in many fields, such as automobile machinery, textile machinery, light industry, and so on, which play a more and more important role in the national economy and people’s daily life.
With the continuous improvement of the standard of the variety of the transmission belt, new material and new technology are used in the production of the drive belt.
Our transmission belt production equipment through years of introduction, digestion, absorption and self development, have made great progress, especially, since the 90s of the 20th century, to the cord production, belt and cutting edge with synchronous belt and multi wedge belt two series as the main generation can meet the needs of China’s drive to belt made. This paper mainly expounds the development of production technology and production equipment in recent years in our country, and introduces the present situation and future development.
Wrapping cloth belt wrapped belt according to the skeleton material and structure can be divided into 7 and reasonable structure of the cloth curtain cloth curtain packaging, uniform force, bending force, etc., can greatly improve the use life of the belt and the use of performance. Advanced industrial countries early in the 20th century, 6 in has completed the belt cord structure upgrading, China to in the late 1990s began large-scale wrapped belt cord structural transformation.
Cord wrapped belt such as according to the section shape and use can also be divided into ordinary belt narrowband automobile belt and agricultural machinery transmission belt etc.. The manufacturing process mainly for each component to cord hanging plastic sheet compression rubber strip extruding cloth cutting and forming cable compression rubber cloth bag, vulcanization, test view performance dimensions.
Cord wrapped belt forming process is the belt body parts are combined into a strip. These processes include tensile cord cable, adhesive film, stretch film and compression film strip joint, wrap cloth and so on. These processes according to different process can finish such as a car with a manual single forming has been gradually phased out, also can be done step by step is to convert the string adhesive film stretch film and compression of the film strip is made into a ladder with a core, the Bucheng strip in the next.
The single drum with core is formed in a single drum forming machine. The single drum forming machine structure similar to the cut edge belt forming machine, mainly by the main transmission device expansion drum cutting sheath device grinding tailstock discharge wire arranging device of cord tension system and electric control system. Qingdao Yi Lida through the digestion and absorption of the machine has completed research projects during nine, and through the identification of the former Ministry of chemical industry. The forming method for anti forming method, namely according to the specifications of the first expansion drum do sheath, accordingly wrap stretch film adhered film cord compression film, followed by knife razed part glue, then disc knife cut with a core. The biggest advantage of this method is the cable tension uniform, high degree of automation. Due to the sheath cutting manufacturing time-consuming and by the expansion drum size limit, and is suitable for single types of specifications, the length of the Yi 2500nmV with mass production.
