Description

Technical Field

[0001] The utility model relates to the technical field of cable production equipment, in particular to a motor-direct-driven cable drum pay-off driving mechanism. Background Art

[0002] Metal wire is widely used in the circuits of various electrical appliances due to its good conductivity and toughness. During the production process, the metal wire on the wire reel needs to be transmitted as needed and processed during the transmission process. However, the wire reel has a large mass due to the large amount of metal wire, and the existing wire reel pay-off device is difficult to translate according to the needs of wire reel pay-off. It is extremely laborious to transport the wire reel to the pay-off device. In continuous production, the amount of metal wire used on the wire reel is large, and workers need to frequently transport the wire reel, which greatly increases the labor intensity of the workers. The existing wire reel pay-off mechanism mostly adopts a belt transmission mechanism to realize the drive connection. However, the drive connection of the belt transmission has more connection structures, which is prone to failure and has power loss for the control of tension during transmission. At the same time, the structure occupies more space. The installation space of some factories is limited, resulting in the inability to install and use the equipment normally. Utility Model Content
