Technical Field
[0001] This utility model relates to the field of shoe support manufacturing technology, and in particular to a shoe support bending mechanism. Background Technology
[0002] Shoe trees, also called shoe stretchers or shoe trees, are common tools inserted into the cavity of shoes to maintain their shape and prevent deformation. They have the effect of maintaining shoe shape and preventing wrinkles. They are usually made of plastic, metal or paper and are commonly used in shoe stores to maintain shoe shape and improve the visual effect.
[0003] Paper shoe supports are an environmentally friendly, lightweight, and economical type of shoe support, mainly used for temporary or short-term use. They are usually supported by recyclable cardboard and are typically made using a hot-pressing and bending process.
[0004] After the hot-pressing and bending process, existing shoe toes require workers to manually remove them from the mold. However, due to the hot-pressing process, workers are prone to burns when removing them. To address this issue, the inventor has proposed a shoe toe bending mechanism to solve the aforementioned technical problems. Utility Model Content

Guide posts are fixedly installed at both ends of the bottom surface of the limiting plate. The guide posts extend toward the inclined surface and are fixedly connected to both ends of the inclined surface. The two ends of the pressing movable plate are movably connected to the guide posts. The guide posts are used to provide directional movement for the pressing movable plate.
[0007] In a further embodiment of the above description, the heating frame is installed on the bottom surface of the lower movable plate, and a heat insulation plate is provided between the heating frame and the lower movable plate. The bottom surface of the heating frame has an installation groove that extends toward the top surface of the heating frame. The upper bending die is detachably installed in the installation groove.

The ejector cylinder drives the top block on the shoe upper to lift the shoe sole. After being lifted, the shoe sole separates from the first, second, and third lower bending dies. After separation, the ejector cylinder resets, and the stepper motor, through the connecting shaft, drives the first and third lower bending dies to rotate in a direction away from the inclined surface, while simultaneously driving the shoe sole to fold together. When folded to a certain angle, the shoe sole, under the action of gravity, naturally falls off the rotating first and third lower bending dies, achieving the removal effect. There is no need for workers to manually remove the bent shoe sole from the mold, preventing burns. Attached Figure Description
