Description

Technical Field

[0001] The utility model relates to the technical field of chain winding, in particular to an automatic chain production winding device. Background Art

[0002] A chain is an assembly of identical or identically spaced components connected in series in the form of kinematic pairs. As an important basic mechanical product, it has the characteristics of both gear transmission and belt transmission and is widely used in machinery, automobile, petrochemical, metallurgy, mining, textile and papermaking fields. The chain needs to go through multiple steps in the production process to form a chain and there are subsequent steps after the chain is formed. In the existing workshop production process, after the chain is output, it is often directly piled up at the unloading end of the production equipment, which easily causes the chains to get entangled with each other. In addition, due to the characteristics of the chain itself, the scattered chains interfere with each other, making it very inconvenient to wind up the chain.

[0003] For example, a patent with a national authorized patent announcement number of CN220906766U discloses an automatic chain production rolling device, which relates to the technical field of chain production equipment, including a base, a plurality of interlayers are arranged inside the base, a hole is opened on the side of the base, a transmission rod is arranged in the hole, a first groove and a second groove are arranged at one end of the transmission rod away from the base, a plurality of gears are installed on the transmission rod, the gears are located in the interlayer, a plurality of tracks are arranged on the upper surface of the base, the tracks are located above the interlayer, a landslide is installed at one end of the base, and a rolling device is arranged at the end of the base away from the landslide, the rolling device includes a support column, the support column is connected to a rotating rod, and a limiting plate is arranged on the outer periphery of the rotating rod. The automatic chain production rolling device of the utility model arranges an elastic steel plate on the track to guide the chain in the track to rise and contact with the permanent magnet arranged on the surface of the rotating rod, and the chain is wound according to the rotation of the rotating rod, thereby reducing the workload of manual chain winding.

[0004] However, the above-mentioned automatic chain production winding device does not have the function of assisting the chain to attach to the sprocket during the chain winding process, which may cause the chain head to fall off during the chain winding process. It also does not have the function of automatically switching the winding disk during the chain winding process. After a roll of chain is produced, the operator needs to manually intervene to replace the new winding disk, which will increase the downtime of the production line and reduce production efficiency.
