7. A spray disinfection method of an automatic spray disinfection system of a filling machine as claimed in any one of claims 1-6, comprising the steps of:

step one: placing a packaging bottle to be sterilized in a carrying groove (3) at the top of a carrying frame (2), then moving the packaging bottle to a designated position to be treated by a conveying belt (100), driving a rotating rod (601) and a sleeve (602) to rotate by a motor (8) until a supporting rod (603) deflects 180 degrees, at this time, the packaging bottle is directly positioned between an upper clamping plate (609) and a lower clamping plate (610), starting an electric first push rod (605), driving the upper clamping plate (609) and the lower clamping plate (610) which are correspondingly arranged to be close to each other by the electric first push rod (605) through pushing a cross rod (608) until the packaging bottle is clamped, and then driving the packaging bottle to deflect into a first spraying box (501) by the supporting rod (603) through a series of structures under the action of the motor (8), wherein a packaging bottle opening is propped against the top of a carrying table (703);

step two: starting an electric push rod II (702), the electric push rod II (702) drives a lifting plate (701) to move upwards until a vertical rod (707) drives a side spray head (708) and an upper spray head (717) to pass through a through groove (704) at the bottom of a bearing table (703) and gradually enter the packaging bottle, the electric push rod III (712) drives the bearing plate (713) and the upper spray head (717) to synchronously move downwards, then a centrifugal pump (12) and a hot water plate heat exchanger (13) are started again, hot water sprayed by the upper spray head (717) and the side spray head (708) performs omnibearing spraying on the surface and the inner wall of the packaging bottle, so that a plurality of substances attached to a glass can are swelled and fall, and the bearing plate (713) drives a folding baffle (715) to descend through a connecting plate (716) in the descending process, so that the first spray box (501) is in a closed state, and the problem of water outflow is effectively avoided.

Step three: after the hot water sprays, when the hot water is required to spray, the water with a certain concentration is prepared in advance and stored in the liquid storage tank (15), the packaging bottles are replaced in the material carrying groove (3) at the top of the material carrying frame (2) under the drive of the motor (8), the packaging bottles move to the position close to the second spraying tank (502) under the cooperation of the conveying belt (100), the packaging bottles are subjected to the omnibearing spraying disinfection on the inside and the outer surface of the rinsing according to the same treatment step of the hot water spraying, the packaging bottles after the spraying are replaced at the top of the material carrying frame (2), and the conveying belt (100) conveys the packaging bottles subjected to the hot water spraying and the water rinsing to a filling area.
