cutting mechanism and a conveying belt; the conveying belt comprises a driving wheel and a belt face, a clamping groove is formed in the belt face, a rubber roll, a feeding roller and a discharging roller are arranged above the belt face,
adhesive tape is wound in the rubber roll, a first transverse shaft is connected to thedriving wheel, a driven gear is arranged on the first transverse shaft in a sleeving manner, a rotation part is rotatably connected to the end face of the driven gear, two magnetic blocks with opposite magnetic properties are connected to the rotating part, a second transverse shaft is arranged on the outer side of the first transverse shaft, a drive mechanism is connected to the second transverseshaft, a
metal bar is connected to the second transverse shaft, a driving gear is connected to the second transverse shaft, the
cutting mechanism comprises an air cylinder and a
cutting knife, the cutting knife is fixedly connected to the air cylinder, the bottom of the cutting knife is provided with an
electric heating wire electrically connected with the
metal bar, an inclined groove is formedin the cutting knife, the high end of the groove is away from the driving gear, a push rod rotatably connected with the rotating part is in sliding connection into the groove, and the two side portions of the cutting knife are rotatably connected with rollers through connecting rods. Automatic sealing of a
carton is achieved.
