Description

Technical Field

[0001] This utility model relates to the field of shoe toe shaping machine technology, and more specifically to a clamping device for a shoe toe shaping machine. Background Technology

[0002] In shoe manufacturing, the shaping of the toe area is a crucial step, directly impacting the shoe's aesthetics. The effectiveness of toe shaping is also a key indicator of shoe quality. Toe shaping generally involves two main steps: first, heat softening the toe surface, followed by cold pressing to shape it. Both heat softening and cold pressing require clamping the toe and heel as a single unit. Especially in the heat softening process, existing toe shaping machines typically only clamp the toe, resulting in the toe not being fully straightened and clamped during softening, easily leading to wrinkles along the shoe's edge and negatively affecting the shaping effect. To address this, the inventor proposes a clamping device for a toe shaping machine. This device clamps the toe and heel of the shoe surface separately, ensuring they are straightened and facilitating a more efficient heat softening process.

[0003] To effectively clamp the shoe upper, facilitate the hot pressing process, and improve shoe manufacturing efficiency, Chinese Patent (Authorization Announcement No.: CN204861489U) discloses a quick mold changing device for a shoe toe shaping machine. This utility model includes a fixed mold frame mounted on a worktable, comprising an upper mold frame and a lower mold frame. The upper mold frame is positioned above the lower mold frame, and a lifting mechanism connects the upper and lower mold frames, allowing the upper mold frame to move up and down along the lower mold frame. The lower mold frame also includes a fixed frame for placing template clamping seats, which are located on the left and right sides of the fixed frame. Each template clamping seat includes a fixing block and a protective plate pressure block, which together form a groove for embedding the template. A tightening screw is provided at the template clamping seat position. This utility model uses clamping seats to quickly and effectively clamp the shoe upper at the toe position, facilitating shaping.

[0004] The solution still has some shortcomings in application. When shaping the toe, the entire upper needs to be clamped, otherwise wrinkles can easily occur at the toe. At the same time, since the shaping machine needs to shape uppers of different sizes, it also needs to have a stretching function to clamp and straighten uppers of different sizes to improve the shaping quality. Therefore, the clamping structure of the shaping machine needs to be improved so that it can clamp the entire upper and straighten it according to different sizes, thereby improving the shaping quality and further enhancing its practicality.
