Description

Clean V-belt production line

Technical Field

The utility model belongs to the technical field of V-shaped belt preparation, and particularly relates to a clean V-shaped belt production line.

Background

With the continuous improvement of the material culture level of Chinese people, the consumption upgrading products emerge endlessly. Especially, the household appliances are updated every year. The transmission V belt is used as a key part of the impeller washing machine and is more concerned by a host machine factory and users, the service life of the washing machine V belt is prolonged from three years to six years, and is prolonged to ten years, and is finally the same as the service life of the whole washing machine, namely, how to change a wearing part into a functional part is a very complex problem faced by production enterprises.

At present, the production of V-belts and outer wrapping fabrics of washing machines at home and abroad adopts the process of dipping the rubber cement. The solid rubber after mixing is put into a stirring tank, then gasoline No. 120 or solvent oil is added, the mixture is fully stirred to prepare liquid rubber (commonly called as sizing agent), and then the liquid rubber is dipped, dried and coiled by a sizing agent machine through a rubber containing groove. This process has a number of disadvantages: firstly, two sides of the canvas are coated with the same amount of rubber, so that the front side and the back side cannot be distinguished; secondly, a large amount of gasoline is volatilized in the production process, so that fire accidents are easily caused; thirdly, the chemical smell of the production workshop is strong, so that the environmental pollution is caused, and the human body is easily damaged; fourthly, the canvas processed by the process is used for producing the V-belt of the washing machine, and cannot meet the requirement of cleanness of a washing machine production enterprise on the transmission V-belt. In the operation process of the V-belt, rubber powder continuously falls off due to heat generated by friction of a working surface, and the rubber powder is continuously blown by a fan on one side of a motor belt wheel to cause pollution at the bottom of an outer barrel of the washing machine and around a transmission module of the washing machine, even pollution to the internal environment of the whole washing machine, and serious failure of a computer board or capacitor breakdown can be caused. When the internal maintenance is opened, the state is often very dark. Therefore, for decades, washing machine V-belts had to be pre-degummed before they were delivered to customers. The manual work and the raw materials are wasted, and because the diamond grinding wheel is driven by the motor, the canvas on the surface of the V-shaped belt is damaged to a certain extent while degumming is carried out, so that the product quality is influenced.
