TECHNICAL FIELD

[0001] The present application relates to the technical field of gluing device, more particularly to the automatic gluing device on the shoe midsole paperboard production line. BACKGROUND

[0002] The current shoe sole generally includes upper, midsole and lower sole, the upper and midsole are called small sole, and the lower sole is called large sole, which improves the utilization rate of energy and environmental protection, and the small sole and large sole can be made of recycled materials (such as paperboard). The production line of some current soles is separate, but there are also production lines of shoe soles and shoe production lines connected to them, and the finished soles are transported to the shoe production line. After the small sole and the upper are sewn, the lower surface of the midsole needs to be glued. At present, glue dispensing machine is mainly used for glue dispensing, that is, the upper with the midsole is sleeved on the shoe last, so that the lower surface of the midsole is horizontally upward, and then the head of the glue dispensing machine dispenses glue on the lower surface of the midsole in multiple points. One midsole needs to be glued multiple times, which cannot effectively improve the production efficiency. Therefore, some people propose to use a rolling brush gluing method to glue, that is, the rolling brush with glue is erected, and the midsole is also erected. The midsole is conveyed by a conveying chain. When the midsole passes through the rolling brush, the gluing is completed, which can improve the gluing efficiency.
