Description

Technical Field

[0001] This utility model relates to the field of plate and frame lifting structure technology, and in particular to a plate and frame lifting structure for a vacuum forming equipment. Background Technology

[0002] In recent years, with the advancement of textile technology, the demand for seamless stitching technology has gradually emerged. Among these technologies, hot pressing is a commonly used method for shaping shoe uppers. Existing technologies generally involve hot pressing and cold pressing devices, along with a worktable. During operation, a mold and the shoe upper to be processed are placed on the worktable. The worktable is then moved to the hot pressing device, where the upper hot plate presses down onto the worktable to shape it. Afterward, the mold and shoe upper are transferred to the cold pressing device, where the upper cold plate presses down onto the worktable to cool it, allowing the thermoformed shoe upper to cool completely. With the development and improvement of shoe upper processing technology, the shoe manufacturing machinery industry has also undergone upgrades. The vacuum forming process required for shoe upper processing is what we call vacuum shaping.

[0003] In existing vacuum mesh frame lifting structures, the lifting mechanism consists of two cylinders mounted on a support base, moving vertically up and down. Because the mesh frame has a certain weight, over time this can lead to cylinder piston rod eccentricity, wear of the sealing rings, and asynchronous lifting between the left and right cylinders, causing the mesh frame to jam and move unevenly. Furthermore, the limited cylinder stroke restricts the shape of the mesh frame, limiting its lifting height and obstructing the worker's view when placing mold materials, making operation inconvenient. Therefore, these technical problems need to be addressed. Utility Model Content
