Bending mechanism for pipeline repair hose production

The invention discloses a bending mechanism for pipeline repair hose production, and relates to the technical field of hose production, the bending mechanism comprises a rack, two folding plates which are symmetrically distributed are rotatably arranged on the rack, the bending mechanism further comprises clamping pieces which are rotatably arranged on the folding plates, and the multiple clamping pieces are arranged at equal intervals; the driving assembly is used for driving the two folding plates to rotate towards the middle of the rack at the same time; the locking assembly is arranged in the folding plate and used for locking the clamping piece; and the unlocking assembly is arranged in the folding plate, and in the rotating and folding process of the folding plate, the unlocking assembly unlocks the locking assembly, so that the clamping piece passively clamps the hose repair material. Through cooperation of the driving assembly, the clamping piece, the locking assembly and the unlocking assembly, in th
