Bobbin and assembling method thereof

Abstract

The invention discloses a bobbin and an assembling method thereof. The bobbin comprises a roller body and stop plates which are arranged at the two ends of the roller body; the roller body is integrally manufactured and formed and comprises a coiled pipe and stop edges which are formed at the two ends of the coiled pipe; an annular groove is formed in the inner side of each stop edge at the corresponding end part of the coiled pipe; a first notch groove is formed in each stop edge; a stop block is arranged at the position, on each annular groove, on the inner side of the corresponding stop edge; a through hole is formed in the intermediate position of each stop plate; a second notch groove is formed in the edge of each through hole; each through hole is formed in the corresponding annular groove in a sleeving manner; each stop block is arranged in the corresponding second notch groove to prevent the corresponding stop plate from rotating. When the bobbin is assembled, the stop edge at one end of the roller body is clamped into the through hole of the corresponding stop plate, one side of each stop edge is clamped into the corresponding second notch groove, each first notch groove in the other side of the corresponding stop edge is clamped at the edge of the corresponding through hole, and the roller body is rotated clockwise until the stop blocks are clamped into the second notch grooves and the through holes are completely formed in the annular grooves in the sleeving manner. The bobbin is detachable and is convenient to transport, so that the transport cost is reduced; the bobbin is assembled easily and quickly, so that the production efficiency can be improved; the quality is more stable because of the integrated roller body of the bobbin.

Description

Technical field [0001] The invention relates to a winding device, in particular to an spool and an assembly method thereof. Background technique [0002] The spool is a winding tool used to wind rope belts, lace belts, 3D printing lines, hoses, zippers, metal wires, steel ropes, etc. The spool generally includes a reel body and baffles at both ends of the reel body. According to the different materials and specifications of the product being wound, the specifications and materials of the spool are also different. Existing spools generally include one-piece and detachable ones. The material of one-piece spools is usually plastic or metal. The price of such one-piece spools is high due to material and production reasons. In addition, the integrated spool cannot be disassembled after it is produced, the overall volume is large, and the space occupied is also large, resulting in increased transportation costs. The existing detachable spool is produced separately from the baffle an...

AI Technical Summary

Problems solved by technology

Although this kind of detachable I-shaped wheel has the advantages of transportation, because the flange and the winding shaft are connected by threads, its assembly and production must have certain technical requirements, which will increase the production cost virtually.
