Energy-saving type single-point heating glue curing device

The invention relates to the technical field of dispensing machines, in particular to an energy-saving type single-point heating glue curing device which comprises a bottom plate, a conveying belt, a side plate and a first mounting plate arranged on the bottom plate, a glue storage box arranged on the first mounting plate, and a positioning mechanism comprising a first electric push rod, one end is fixedly connected with the side plate, and the other end is slidably connected with the first positioning plate through a sliding mechanism. A first motor is controlled to sequentially and positively and negatively alternately drive a cross rod to rotate by an angle, so that two groups of dispensing machines sequentially move to a position below a second electric push rod for dispensing operation, meanwhile, a fourth motor drives a driving rod to rotate, and the driving rod drives a cleaning rod to rotate through a transmission belt; and the rotating cleaning rod can clean residual glue on a glue outlet in the bott
