Description

Full-automatic sole rubberizing line printer

Technical Field

The invention relates to sole processing equipment, in particular to a full-automatic sole gluing and scribing machine.

Background

In the shoes manufacturing industry, sole, vamp are generally separately produced, then with the sole with the vamp laminating each other, generally adopt the mode of glue laminating, consequently, need coat a glue film in advance in the side of sole, this glue film needs to satisfy certain altitude requirement and can not be full with the side of sole completely. Therefore, before the sole side is glued, an annular marking line is often drawn on the side of the sole according to the preset gluing requirement, and then the sole side below the marking line is glued, so that the glue layer coated can meet the preset requirement. And because the side surface of the sole is uneven, the marking line on the side surface of the sole is difficult to automatically mark by adopting a machine. In the past, the idea that the marking pen is fixed and automatic marking is realized through rotation of the sole is provided, but the idea is not feasible at all because the distance difference between the marking pen and the toe cap, the heel and the side face of the sole is too large, and the problem that the marking pen and the sole are inevitably blocked due to the sudden change of the distance in the rotation process of the sole cannot be solved, so that in the shoe manufacturing industry, at present, only manual marking can be performed only through manual marking, manual marking needs a worker to hold the sole with one hand and carry a pen with the other hand for annular marking, the angle of the sole needs to be continuously changed and the angle of the pen point needs to be adjusted, and the problems are quite troublesome, low in production efficiency, easy to make mistakes in marking and low in accuracy.
