Description

Technical Field

[0001] This application relates to the technical field of shoe production, and in particular to a glue coating device for shoe production. Background Art

[0002] In the process of shoe production, in order to bond the shoe upper and the sole together, it is usually necessary to spray glue on the sole. A glue coating machine is mainly a mechanical device used to apply liquid glue on the surface of textiles, paper boxes or leather. The coating machine sprays the glue onto the required products through air pressure and applies glue to the shoes during production.

[0003] However, for existing glue coating machines with a relatively high degree of automation, the glue coating head is usually controlled by a robotic arm. The price and maintenance cost of the robotic arm are difficult for some start-up enterprises to bear. In view of the above related technologies, the applicant proposes a glue coating machine that has fewer control modules, reduces the equipment investment in the research and development and trial-and-error processes, and can complete the adaptive control spraying of the sole with a simple mechanical structure.

The height assisting mold 41 is placed parallel to the frame 1 on one side of the positioning mold 2, and the upper surface height of the height assisting mold 41 is set corresponding to the upper surface height of the shoe sole. And the height assisting mold 41 is a shoe sole filled with materials such as clay in the gaps, so that the surface is smooth to form a continuous curve; one end of the lifting connecting rod 42 is fixed to the glue application structure 3, and the other end extends towards the upper surface of the height assisting mold 41; the sliding ball 43 is rotatably connected to one end of the lifting connecting rod 42 close to the height assisting mold 41, and the sliding ball 43 abuts against the upper surface of the height assisting mold 41, so that the lifting connecting rod 42 changes in height with the undulation of the height assisting mold 41.
