Pulling the small adjustment plate outwards adjusts the hot air output flow to a moderate level. When pulling the medium adjustment plate outwards, hot air passes sequentially through the duct exhaust fan and the guide box, allowing for a large-diameter guide hole hot air flow output to the preheating chamber. Pushing both the small and medium adjustment plates back into the pull-out chamber simultaneously minimizes the hot air flow, thus forming a waste heat extraction and guide hole diameter adjustment structure. This structure offers the advantage of heat recovery and utilization. Simultaneously, the guide box evenly discharges hot air, and the hot air output flow can be adjusted according to the bottle size, achieving uniform preheating of the bottle and reducing the occurrence of deformation, cracks, or breakage.

All of the above are existing technologies and can be implemented using existing technologies.

[0035] Example 2

[0036] Please see Figure 1-7 The preheating section 3 is located on the outside of the sterilization dryer body 2. The preheating section 3 includes a preheating box 301 bolted to the top surface of the workbench 1. The preheating box 301 is hollow, which facilitates the conveyor belt mechanism 4 to transport the bottles into the preheating box 301. Movable sliding doors are provided on both sides of the preheating box 301. The height of the sliding doors can be adjusted to accommodate bottles of different heights and reduce heat loss. Exhaust pipes 302 are bolted to both sides of the preheating box 301. The end of the exhaust pipe 302 away from the preheating box 301 is bolted to the outer wall of the sterilization dryer body 2. The exhaust pipe 302 is connected to the heating area inside the sterilization dryer body 2, which facilitates the conduction of heat to the inside of the preheating box 301 to preheat the bottles and achieve the effect of heat recovery and utilization.

[0037] An exhaust fan 303 is installed inside the exhaust duct 302. The preheating chamber 301 is interconnected with the interior of the exhaust duct 302. The exhaust duct 302 is interconnected with the interior of the exhaust fan 303 and the sterilization dryer body 2. When the exhaust fan 303 is started via the control terminal, the residual heat inside the sterilization dryer body 2 can be discharged into the interior of the preheating chamber 301. A guide box 304 is bolted to the side of the preheating chamber 301 away from the exhaust duct 302. A pull-out cavity 305 is opened inside the guide box 304. The pull-out cavity 305 is interconnected with the interior of the exhaust duct 302. Hot air is discharged into the interior of the preheating chamber 301 through the exhaust duct 302 and the guide box 304 in sequence. An orifice adjustment component is installed inside the pull-out cavity 305. By starting the exhaust duct 302 and adjusting the orifice adjustment component, the residual heat inside the sterilization dryer body 2 is introduced into the interior of the preheating chamber 301 to preheat the bottles.

[0038] Example 3

[0039] Please see Figure 1-7The aperture adjustment components include a medium-sized adjustment plate 306 and a small-sized adjustment plate 307 slidably disposed inside the pull-out cavity 305. The medium-sized adjustment plate 306 has multiple sets of medium-sized guide holes inside, and the small-sized adjustment plate 307 has multiple sets of small-sized guide holes inside. Sliding grooves 308 are provided on both the top and bottom surfaces inside the pull-out cavity 305. The guide box 304 has multiple sets of large-diameter guide holes inside. Two sets of sliding grooves 308 are provided, symmetrically distributed along the transverse central axis of the preheating chamber 301. The two sets of sliding grooves 308 are respectively positioned above and below the medium-sized adjustment plate 306 and the small-sized adjustment plate 307. The inner walls of both sets of sliding grooves 308... A sliding support rod 309 is connected by screws. The sliding support rod 309 is horizontally arranged inside the sliding groove 308. A sliding sleeve block 310 is slidably sleeved on the outer side of the sliding support rod 309. The outer walls of the medium-sized adjustment plate 306 and the small-sized adjustment plate 307 are bolted to the side of the sliding sleeve block 310 away from the sliding groove 308. When the medium-sized adjustment plate 306 or the small-sized adjustment plate 307 is pulled outward, the medium-sized adjustment plate 306 and the small-sized adjustment plate 307 drive the sliding sleeve block 310 to slide on the outer side of the sliding support rod 309. Therefore, it can provide support and sliding function for the top and bottom ends of the medium-sized adjustment plate 306 and the small-sized adjustment plate 307.

[0040] By pulling the small adjustment plate 307 outwards, hot air passes sequentially through the duct exhaust fan 303, the medium adjustment plate 306, and the interior of the preheating chamber 301, thus adjusting the diameter of the guide hole to a medium size. When the medium adjustment plate 306 is pulled outwards, hot air passes sequentially through the duct exhaust fan 303 and the guide box 304, maintaining a large-diameter guide hole hot air flow output to the preheating chamber 301. Therefore, when the small adjustment plate 307 and the medium adjustment plate 306 are pushed back into the pull-out chamber 305, the hot air flow can be adjusted to the minimum, thus forming a structure with an adjustable guide hole diameter, achieving the purpose of adjusting the hot air output flow and improving preheating uniformity.

[0041] A fixing block 311 is provided below the medium-sized adjusting plate 306 and the small-sized adjusting plate 307. One end of the fixing block 311 is bolted to the outer wall of the preheating box 301. The inner wall of the fixing block 311 is in contact with the bottom surface of the medium-sized adjusting plate 306 and the small-sized adjusting plate 307. A small threaded rod 312 is provided below both the medium-sized adjusting plate 306 and the small-sized adjusting plate 307. Two sets of small threaded rods 312 are provided on the side of the fixing block 311 away from the small-sized adjusting plate 307 and the medium-sized adjusting plate 306. The end of the threaded rod 312 passes through the interior of the fixing block 311 and the medium-sized adjusting plate 306 in sequence, and is threadedly connected to the inner side of the fixing block 311 and the medium-sized adjusting plate 306. The end of the other set of small threaded rods 312 passes through the interior of the fixing block 311 and the small-sized adjusting plate 307 in sequence, and is threadedly connected to the inner side of the fixing block 311 and the small-sized adjusting plate 307. Threaded slots are provided on the parts of the medium-sized adjusting plate 306 and the small-sized adjusting plate 307 near the fixing block 311. Threaded slots are provided inside the fixing block 311.

[0042] When the end of the small threaded rod 312 is held and continuously rotated, the tip of the small threaded rod 312 can be rotated and inserted into the fixing block 311, the small adjusting plate 307, or the medium adjusting plate 306, thus securing the small adjusting plate 307 and the medium adjusting plate 306 back into the pull-out cavity 305. When the end of the small threaded rod 312 is held and continuously rotated in the opposite direction, the tip of the small threaded rod 312 can be sequentially moved out of the fixing block 311, the small adjusting plate 307, or the medium adjusting plate 306. Internally, the fixing measures of the medium-sized adjustment plate 306 or the small-sized adjustment plate 307 are removed to facilitate the readjustment of the hot air output flow rate. The outer walls of the medium-sized adjustment plate 306 and the small-sized adjustment plate 307 are welded with plug strips 313. The pull-out cavity 305 has a slot 314 on the side wall near the plug strip 313. The plug strip 313 and the slot 314 form a transverse plug-in structure. The plug-in state of the plug strip 313 and the slot 314 improves the stability of the side walls of the small-sized adjustment plate 307 and the medium-sized adjustment plate 306.

[0043] Working principle: First, hold the bottom end of the small threaded rod 312 and rotate it continuously until the end of the small threaded rod 312 near the fixed block 311 moves out of the small adjustment plate 307 and the medium adjustment plate 306, releasing the fixing measures on the medium adjustment plate 306 and the small adjustment plate 307. Then, pull out the small adjustment plate 307 or the medium adjustment plate 306 according to the size of the bottle to be sterilized and dried.

[0044] Next, after pulling the small adjustment plate 307 outward, the hot air passes through the duct exhaust fan 303, the medium adjustment plate 306, and the interior of the preheating box 301 in sequence, allowing the hot air output flow rate to be adjusted to a moderate level. When pulling the medium adjustment plate 306 outward, the hot air passes through the duct exhaust fan 303 and the guide box 304 in sequence, allowing the hot air flow rate of the preheating box 301 to be output through the large-diameter guide hole. When the small adjustment plate 307 and the medium adjustment plate 306 are pushed back into the pull-out cavity 305 at the same time, the hot air flow rate can be adjusted to the minimum. After adjusting the flow orifice diameter according to the bottle size, hold the bottom end of the small threaded rod 312 again and rotate it until the small threaded rod 312 is inserted into the rotating insertion fixing block 311, the small adjustment plate 307, or the medium adjustment plate 306, completing the fixing measures for the medium adjustment plate 306 or the small adjustment plate 307.

[0045] Finally, the bottles to be dried and sterilized are placed on the surface of the conveyor belt mechanism 4. The sterilization dryer is started through the control terminal. After the conveyor belt mechanism 4 starts, it transports the bottles to the interior of the preheating chamber 301. The exhaust fan 303 discharges the residual hot air into the interior of the exhaust pipe 302. The exhaust pipe 302 then discharges the residual hot air into the interior of the guide box 304. The guide box 304 discharges uniform hot air to preheat the bottles. Then, the conveyor belt mechanism 4 continues to transport the bottles to the interior of the sterilization dryer body 2. The heating module inside the sterilization dryer body 2 continues to heat up and sterilize the bottles, finally completing the work.
