Description

TECHNICAL FIELD

[0001] The utility model relates to a coiling machine technology field, concretely is a kind of coiling machine solid drum clutch device. BACKGROUND

[0002] In the working process of strip coiler, the steel strip needs to be coiled by the drum. Currently, there are two kinds of coiling drums, one is the expansion drum, and the other is the solid drum. When the solid drum is used to coil the steel strip, a clutch device is needed to connect the solid drum and the transmission device.

[0003] The prior art with publication number CN211100864U discloses a coiling machine solid drum clutch device, which includes a speed reducer placed on the coiling machine. The power input shaft of the speed reducer is in transmission connection with the driving device of the coiling machine. The output end of the power output shaft is coaxially and spacedly distributed with the solid drum. A pull rod is axially sleeved in the power output shaft. An inner tooth sleeve is arranged between the power output shaft and the solid drum. An extension mechanism is installed outside the speed reducer. The extension end of the extension mechanism is in transmission connection with the other end of the power output shaft through a rotating piece. The driving device drives the speed reducer to drive the pull rod and the inner tooth sleeve to rotate synchronously with the power output shaft. The inner tooth sleeve and the solid drum are respectively provided with meshing teeth and tooth grooves on one end thereof.
