The reeling of the thin strip in the strip steel production line, particularly the last reeling of the bright plate, needs to be assisted and reeled by a belt wrapper because a jaw of a reeling machine cannot be used to avoid crease marks.

Chinese patent No. CN 210847708U discloses a novel belt rolling aid, which comprises a base and a rolling aid main body; the winding assisting main body is arranged on the base and comprises a main block body, two groups of winding assisting assemblies and a belt, wherein one end of the main block body is provided with a containing groove, the main block body is opposite to the top and the bottom of the containing groove to form two pairs of mounting arms, the two groups of winding assisting assemblies are oppositely arranged on the two mounting arms, each winding assisting assembly comprises an arm, a fixing seat and an arm driving piece, each arm is hinged with the end part of the corresponding mounting arm, one surface of each arm, facing the containing groove, is provided with an arc-shaped groove, a plurality of winding assisting rollers are arranged on the arc-shaped grooves at intervals at preset intervals, the fixing seats are correspondingly arranged on the top or the bottom of the main block body, and a push rod of each arm driving piece is hinged with each arm; and two ends of the belt are oppositely wound on the main block body and the auxiliary winding roller of the holding arm.

The prior art has the following technical defects: the novel belt wrapper using the technology is used in the wrapper process of the strip steel:

when the upper coiling and wrapper-assisting or the lower coiling and wrapper-assisting are used, because the strip steel is thin strip steel, the two wrapper-assisting assemblies can only act one group, and because the two wrapper-assisting assemblies are too large in appearance, only one group of wrapper-assisting rollers wrapped by the other group of belts is large in distance relative to the working wrapper-assisting assemblies, and the wrapping angle of the actual wrapper-assisting belts generated by the belts is too small, when wrapper-assisting is generated, especially when the first circle of strip steel cannot be tightly wrapped on the coiling reel, and finally the wrapper-assisting device returns to a non-working position, the coiling tension slips to influence coiling;

the main block faces to the winding assisting roller of the arc-shaped groove arranged in the accommodating groove, and because the belt forms an inner side wrapping circle relative to the winding drum at the working position, the belt is not required to be arranged and is not beneficial to replacing the belt at the later stage;
