Description

Technical Field

[0001] The utility model relates to the technical field of curling equipment, in particular to a curling device for flanging and forming a vertical axial flow fan. Background Art

[0002] The curling machine consists of a frame, an automatic lifting mechanism, and an automatic curling mechanism. The characteristic is that a threaded clutch is welded on the frame. The main shaft is divided into five sections, three straight sections, and two threaded sections. There are three rotating rods distributed at 120 degrees. There is a roller at one end of the rotating rod and a roller at the other end. The motor drives the main shaft through the worm gear and worm drive to drive the automatic lifting mechanism and the automatic curling mechanism to work, and the entire curling process is completed automatically. The workpiece rotates at high speed, and the upper and lower edges of the workpiece are squeezed and deformed to form a curling effect.

[0003] A curling device for a conical paper cup forming machine that is convenient for collecting and releasing conical paper cups is disclosed in the Chinese utility model patent application publication specification CN216610245U, which includes a support frame, a rotating plate and a motor. The inner upper end of the support frame is fixedly connected to a first hydraulic rod, the lower end of the first hydraulic rod is fixedly connected to a conical pressing plate, the inner side of the conical pressing plate is slidably connected to a curling template, the inner lower end of the support frame is rotatably connected to the rotating plate, the upper end of the rotating plate is fixedly connected to a fixed rod, the upper end of the fixed rod is fixedly connected to two placement racks, the right side of the support frame is fixedly connected to a first hydraulic press, the upper end of the first hydraulic press is connected to a second hydraulic rod, the upper end of the second hydraulic rod is connected to a top block, the upper side of the right end of the support frame is fixedly connected to a storage tube, the inner side of the lower end of the storage tube is rotatably connected to a limiting plate, the conical paper cup is placed by the placement rack through the conical pressing plate, the curling template and the placement rack, and the conical pressing plate can be moved up and down by the action of the first hydraulic rod, so that the conical pressing plate contacts the conical paper cup.

[0004] However, the device lacks the function of adjusting the structure to adapt to the processing of materials of different sizes. The structure that cannot be adjusted during use cannot perform curling on materials of different sizes, which reduces production efficiency and requires the purchase of corresponding equipment according to materials of different sizes, increasing investment costs. Moreover, the device lacks the function of facilitating the disassembly and installation of the mold. During use, the mold flanges the material for a long time, which is not convenient for replacement and maintenance, and the mold wears out, resulting in poor flanging effect of the worn mold on the material, and failure to provide reliability for the curling of the material.
