Description

Technical Field

[0001] The utility model relates to the technical field of shoe processing, in particular to an automatic cutting device for shoe upper materials. Background Art

[0002] The automatic cutting machine for shoe upper materials is composed of a moving mechanism, a lifting mechanism, a pressure seat, and a mold. The shoe upper material is initially a large-area material and is spread flat on the conveyor. The moving mechanism drives the lifting mechanism to move left and right for cutting. The mold is installed at the bottom of the pressure seat. The lifting mechanism drives the pressure seat to descend, allowing the mold to squeeze and cut the shoe upper material. After cutting the current row, the conveyor drives the shoe upper material to move and cut the entire row at the next position.

[0003] In the process of implementing this solution, the inventors found that the following problems in the prior art have not been well solved: since the mold is a groove-shaped mold, after cutting is completed, the material often gets stuck inside the mold, especially for some rubber upper materials, which are more likely to get stuck, resulting in the depth inside the mold becoming shallower. If multiple layers of material are cut together, the depth inside the mold will be relatively deep, which will result in the inability to complete the cutting thoroughly the next time. The material stuck inside the mold still needs to be manually removed, which is time-consuming and labor-intensive and affects work efficiency. Utility Model Content
