When the film blowing machine reels the material, it usually uses a reel to reel it in. When ordinary reels are reeling, it is easy for the material to fall off and wrap around the reel, resulting in unbalanced reeling, which leads to uneven reeling and requires repeated work to restore the reeling. The labor degree is large and the work efficiency is low. In order to prevent the above accidents from happening, a guide device is usually used to assist in reeling. The prior art publication number CN219990662U proposes a winding guide device for a seven-layer co-extrusion film blowing machine, comprising a winding shell and a winding guide mechanism arranged on the winding shell, wherein a motor is fixed to one side wall of the winding shell, and a storage groove is formed at one end of the winding shell on the side where the motor is located, wherein the storage groove passes through the top wall of the winding shell, and the inner walls on both sides of the storage groove are rotatably connected with a columnar support shaft, the output shaft of the motor passes through the winding shell and is coaxially connected to one of the support shafts, and a winding roller is horizontally arranged in the storage groove, and extension columns are symmetrically welded at both ends of the winding roller, and positioning grooves are formed on the outer walls of the two support shafts toward the inside thereof.
