Description

Hot melt machine

The invention relates to a hot melt glue dispenser, in particular to a hot melt glue machine applied to shoe processing.

The dispensing machine is a processing equipment frequently used in the processing of the footwear industry. The glue is applied to the shoes that are still in the semi-finished state, and the operator controls the dispensing machine to move the dispensing head or the glue gun of the dispensing machine. In order to meet the needs of on-site processing, the gluing operation is performed on the upper or the sole of the processed shoe.

In the prior art dispensing operation, the processing shoes are first placed on the fixture board on the dispensing machine table, and the glue head or the glue spraying gun is displaced on the machine table to move to the glued parts required for processing the shoes.
