Description

Technical Field

[0001] The utility model relates to the technical field of assembly lines, and particularly relates to a general-purpose assembly line with rotatable speed adjustment. Background Art

[0002] An assembly line is a commonly used material conveying and transfer device in industrial production processes. According to different structural forms of the assembly line, it can be divided into: linear assembly lines, branch assembly lines, circulating assembly lines, and parallel assembly lines. Taking the circulating assembly line as an example, its structure usually includes a circular conveyor line and a carrying platform. Materials are placed on the carrying platform and run along with the circular conveyor line. When the materials reach the designated workstations, operators remove the materials, and then the circular conveyor line continues to operate. However, the material carrying platform of this kind of assembly line is usually fixedly arranged on the circular conveyor line, and the form of the carrying platform is also specific. Therefore, it can only be used for specific products separately according to requirements. In short, the assembly line is used for one-to-one use of individual products, lacking commonality and versatility. Moreover, the carrying platform of the existing assembly line cannot be adjusted in angle, and it is not convenient to pick up materials. Therefore, it needs to be improved.
