Device for spraying adhesive to shoe vamp

Abstract

The invention provides a device for spraying an adhesive to a shoe vamp. The device comprises a conveyor, a multi-joint manipulator and a support, wherein the multi-joint manipulator and the support are located beside the conveyor, an adhesive cup is fixedly connected to the support, the tail end joint of the multi-joint manipulator is fixedly connected with a spray gun rack, a spray gun is installed on the spray gun rack, and an included angle formed by the spray gun and the tail end joint of the multi-joint manipulator is 45 degrees. Due to the fact that the included angle formed by the spray gun and the tail end joint of the multi-joint manipulator is 45 degrees, the spray gun is naturally and obliquely arranged after the tail end joint of the multi-joint manipulator is arranged vertically, the adhesive can be simultaneously sprayed to stitch positions of the inside of the bottom of the shoe vamp and the side edge of the shoe vamp during adhesive spraying, namely simultaneous adhesive coating of the stitch positions of the inside of the bottom of the shoe vamp and the side edge of the shoe vamp can be achieved through one-time adhesive spraying action, and the production efficiency is relatively higher. In addition, due to the fact that the adhesive cup is arranged, an adhesive brush can be soaked in the adhesive cup when the adhesive spraying action is not executed and is not prone to curing, frequent spray gun and spray head replacement is also not needed, and the cost is relatively lower.

Description

technical field [0001] The invention relates to shoe-making equipment, in particular to a shoe upper glue spraying device. Background technique [0002] In the production of shoes, before the upper and the sole are bonded to each other, in addition to the need to apply glue to the sole, it is also necessary to apply glue to the bottom of the upper and the seam where the side of the upper and the sole are bonded. The positions that need to be glued on the surface are located at the bottom and the side respectively. Usually, two glue brushing actions are required, and the production efficiency is relatively low. [0003] In addition, in the process of applying glue, the glue brush will inevitably need to be exposed to the air after being glued. The glue on the glue brush is easy to cure, and the brush needs to be replaced frequently, which is relatively expensive. [0004] In view of this, the applicant has carried out in-depth research on the structure of the shoe upper glue...
