Feeding device of SMT printing machine

The utility model relates to the technical field of solder paste printing machines, and discloses a feeding device of an SMT printing machine, which comprises a fixed bottom plate, a mounting plate is fixedly mounted on the front side of the fixed bottom plate, a first motor is fixedly mounted on one side of the mounting plate, a bearing is fixedly mounted on the front side of the fixed bottom plate, the first motor drives a first synchronizing wheel to rotate, and the first synchronizing wheel drives a second synchronizing wheel to rotate. And after a fixed bottom plate moves downwards to a proper height, a user starts a telescopic air cylinder, the telescopic air cylinder drives a material pressing block to enter a solder paste barrel and extrude solder paste in the solder paste barrel, and the solder paste in the solder paste barrel is extruded through the material pressing block. Solder paste in the solder paste barrel is discharged through the solder paste extruding nozzle under the action of pressure, a
