In order to solve the problems, the following technical scheme is provided:

the utility model discloses a supplementary device of rolling up of strip includes the frame, has the batching of horizontal arrangement to rise the head that contracts in this frame. The device is characterized in that a rotating shaft is arranged on the rack above the reeling expansion head, the rotating shaft is in rotating fit with the bracket, and a driving mechanism for driving the rotating shaft to rotate is arranged between the rotating shaft and the bracket. The rotating shaft is fixedly provided with a connecting arm, one side of the connecting arm corresponding to the reeling expansion and contraction head is provided with an arc-shaped notch, and the distance from the axis of the notch to the rotating shaft is equal to the distance from the axis of the reeling expansion and contraction head to the rotating shaft. One end of the notch far away from the rotating shaft is hinged with a clamping arm, and a belt is arranged between one end of the notch close to the rotating shaft and one end of the clamping arm far away from the connecting arm. And a connecting rod extending outwards is fixed on the outer side of the clamping arm, and a driving cylinder is hinged between the outer end of the connecting rod and the connecting arm.

The clamping arm comprises a straight line section and an arc-shaped section, one end of the straight line section is hinged to the connecting arm, the other end of the straight line section is fixed to one end of the arc-shaped section, and the belt is located between the other end of the arc-shaped section and one end of the notch.

The driving mechanism is a motor.

By adopting the scheme, the method has the following advantages:

because the utility model discloses a coiling of supplementary coiling apparatus batches the frame that contracts head top and has the pivot, there is the actuating mechanism who is used for driving pivot pivoted between pivot and support, be fixed with the linking arm in the pivot, it has curved breach to batch linking arm one side that contracts the head and correspond, it has the clamp arm to keep away from one of the breach of pivot to serve articulated, there is the belt between the clamp arm one end of being close to breach one end of pivot and keeping away from the linking arm, the outside of clamp arm is fixed with the connecting rod that outwards stretches out, it has the driving cylinder to articulate between the outer end of connecting rod and linking arm. When in use, the hollow sleeve is firstly placed on the coiling expansion and contraction head to be tensioned and fixed. Then, the driving mechanism drives the connecting arm to rotate, so that the notch and the hollow sleeve are concentric. Then, the piston rod of the driving cylinder extends out, so that the belt is coated on one side of the hollow sleeve. Then, one end of the belt material enters between the belt and the hollow sleeve and is pressed and fixed by the belt. And then, the hollow sleeve is driven to rotate by the expansion and contraction head, and the strip material is tightly wrapped on the hollow sleeve after the strip material is wrapped on the hollow sleeve for 1-2 circles. And finally, the driving cylinder is contracted, the driving mechanism drives the connecting arm to reset, and the coiling expansion and contraction head continues to drive the hollow sleeve to rotate to complete coiling. The auxiliary coiling device can realize automatic coiling, has good centering effect compared with manual coiling, does not need to be contacted with a strip material by a worker, has high safety and does not have potential safety hazard. Moreover, the auxiliary coiling device does not need to process a jaw on the hollow sleeve, so that the strength of the hollow sleeve cannot be reduced, and the hollow sleeve is not easy to deform, does not need to be reground, and cannot be damaged or scrapped under the combined action of coiling tension and wrapping force.
