The invention relates to a dispensing machine used for sticking a cover of wet towel. The dispensing machine comprises a support, a conveyor belt, a sensor, a gear mechanism, a heat melt machine and a control device, wherein the conveyor belt is disposed on the support, the sensor is disposed on the support, the gear mechanism comprises an air cylinder, an air cylinder seat frame and a block. The dispensing machine is characterized by also comprising a lateral movement mechanism, a longitudinal movement mechanism and a glue spraying nozzle, wherein the glue spraying nozzle is disposed at one end of a supporting rod, the other end of the supporting rod is fixed on the longitudinal movement mechanism. The moving trajectory of the glue spraying nozzle is a square or a circle, and the glue is dispensed in a linear manner. Compared with a conventional technology of brushing the glue on the surface, the dispensing machine can save glue amount and is convenient for use.
