Problems and solutions in the design and manufacture process of roller.With the rapid development of China's capital construction and technological progress, a large number of construction of the drainage pipeline project, for the roller to provide a broad market. The demand of the society has driven the development of the enterprise. Now the concrete drainage pipe enterprise has spread all over the country, some enterprises in the big city have introduced the advanced roller equipment.

     At the same time, it also brings a new flexible interface pipe, which has played a good role in promoting the production of reinforced concrete drainage pipe. In order to meet the requirements of the majority of drainage pipe production enterprises, many machinery manufacturing enterprises are committed to the development, design, production of high quality and low price drainage equipment.

     Drainage equipment mainly includes hanging roller cement pipe machine (hereinafter referred to as roller machine) and reinforced concrete drain pipe steel mold (hereinafter referred to as cement pipe mold) two parts. The roller is composed of the main motor, the transmission mechanism, the feeding mechanism, the main frame, the main transmission shaft, the rod shaft and the movable door frame.
