the sterilization structure mainly comprises a sterilization lamp structure and an ozone sterilization structure which are respectively aimed at the outer wall and the inner wall of the capsule;

when the capsule mold 11 drives the formed hollow capsule to enter the dark box 13, the outer surface of the capsule is irradiated for sterilization through the sterilizing lamp structure, and the sterilizing lamp structure intermittently performs a light upward irradiation process, so that the light can be prevented from leaking in the sealing process when the capsule forming structure is fed and discharged, specifically, the driving shaft 14 drives the rotating roller 15 to rotate continuously, when the sterilizing lamp beads 16 on the rotating roller 15 face upward, the capsule sterilization is performed, and when the sterilizing lamp beads 16 rotate downward, the light can be absorbed through the dark box 13, the sterilizing lamp beads 16 adopt a normally open arrangement, the phenomenon that the lamp beads are subjected to the impact of continuous high-voltage pulse when the light is continuously turned on to influence the service life is prevented, but considering that the sterilizing lamp beads 16 normally open can accumulate a large amount of heat, when the sterilizing lamp beads 16 rotate to the bottom of the dark box 13, through a low-temperature area formed by the refrigerating plate 19, the rapid heat exchange can be carried out, the temperature at the sterilizing lamp bead 16 is reduced, and the service life is ensured;

the sterilization box 25 is driven to ascend and descend by using a telescopic driving structure, so that the sterilization box 25 can avoid when the capsule forming structure goes in and out, and the capsule forming structure moves downwards when the capsule forming structure is paused and is pressed on the capsule forming structure to sterilize, concretely, the driving structure mainly drives the sterilization box 25 to move by using the air cylinder 21, and uses a guide structure formed by the guide rod 22, the support spring 23 and the slide block 24 to carry out auxiliary support on the sterilization box 25, so that the movement of the sterilization box 25 is smoother, smoother and straighter, when the sterilization box 25 is pressed downwards by the driving structure, on one hand, the capsule forming structure is unfolded and forms a sealed cavity with the sterilization box, on the other hand, the air supply pipes 29 in the sterilization box 25 are tightly connected with the vent holes 12 on the capsule mold 11, and the number of the air supply pipes 29 is consistent with the number of the capsule molds 11, and point-to-point connection is carried out, when the sterilization starts, the air is supplied to the sterilization box 25 through the air supply pipe 30, oxygen is converted into ozone in the ozone discharge pipe 25 by using the high-voltage discharge principle, and the ozone is sent to the inside of the capsule mold 11 along the vent hole 12 and enters the cavity wall of the hollow capsule to effectively sterilize the inner wall of the capsule;

considering that the air supply pipe 30 is connected with the top of the capsule mold 11 in a contact way and is not completely sealed when the ozone sterilization structure is used for sterilization, ozone is dissipated, the ozone is mainly present below the isolation plate 27, the sterilization box 25 and the cavity formed by the capsule molding structure, after the sterilization is finished, the capsule mold 11 and the capsule have residual ozone, the ozone has foul smell and is very difficult to eat after being dissipated into the air, so the ozone recovery structure is used for recovering the ozone at the two places, in the ozone recovery structure, the second recovery pipe 35 is directly connected with the sterilization box 25, the ozone dissipated at the connecting position of the air supply pipe 30 and the capsule mold 11 is absorbed, the top plate 31 is connected with the side surface of the sterilization box 25 and can move downwards along with the side surface, when the capsule molding structure which is sterilized moves to the bottom, the air suction pipe 33 on the caisson 32 is connected with the vent hole 12 on the capsule mould 11 point to point, so that the first recovery pipe 34 connected with the caisson 32 is used for extraction, and no ozone residue is ensured in the capsule;

and because the existence of the upper and lower pressure levers 6 of the movable frame 5, because of the structural requirement, the sterilization box 25 is provided with a pressing groove, so a gap of the contact part of the pressing groove and the pressure block 7 is reserved during sealing, the external sealing structure is used for supplementary sealing, the external sealing structure uses the insertion rod 43 as a drive, the insertion rod 43 is connected to the sterilization box 25 and can move downwards along with the insertion rod, when the insertion rod 43 enters the sterilization box from the insertion hole 42 on the hollow block 41, the insertion rod can contact one end of the lever 40 to tilt the lever, so that the rotating plate 37 is driven to rotate through the connecting rod 39, the isolation cover 38 covers the sterilization box 25 at the position of the pressing groove, the effective supplementary sealing is carried out, the integrity of the whole structure is ensured, and the sterilization work of the capsule can be safely carried out.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
