[0022] Embodiment 1
[0023] The following with reference to the attachedFigures 1-5 A further description of the present utility model is as follows:
[0024] The present utility model provides a hot air circulation tunnel sterilization oven 10. Please refer to Figures 1-5 . The hot air circulation tunnel sterilization oven 10 includes an oven main body 100 and a driving mechanism 200.
[0025] Among them, the oven main body 100 includes a drying section 110, a front door cover 140 connected to the feeding end 120 of the drying section 110 and capable of opening and closing the feeding port 130 of the drying section 110, and a rear door cover 170 connected to the discharging end 150 of the drying section 110 and capable of opening and closing the discharging port 160 of the drying section 110.
[0026] In this embodiment, a plurality of limiting grooves 180 are recessed in both the feeding end 120 and the discharging end 150. The extending direction of the plurality of limiting grooves 180 is perpendicular to the length direction of the drying section 110. A plurality of limiting bars 190 are convexly provided on either the front door cover 140 or the rear door cover 170. Each limiting bar 190 is correspondingly embedded in the limiting groove 180 and can slide along the length direction of the limiting groove 180.
[0027] In this embodiment, the front door cover 140 and the rear door cover 170 are simultaneously connected to the driving mechanism 200 and can be lifted and lowered synchronously.
[0028] Specifically, in this embodiment, the driving mechanism 200 includes a driving member 210 and two sets of lifting assemblies 220 arranged symmetrically. The driving member 210 includes a motor.
[0029] Among them, the lifting assembly 220 includes a first rotating shaft 221, a second rotating shaft 222, a first rotating wheel 223, a second rotating wheel 224, a first gear 225, a second gear 226, a rack 228 and a conveyor belt 229. The axis lines of the first rotating shaft 221 and the second rotating shaft 222 are arranged in parallel, and the axis lines are perpendicular to the length direction of the drying section 110. The first rotating shaft 221 and the second rotating shaft 222 are rotatably connected to the side wall of the drying section 110. The first rotating wheel 223 and the first gear 225 are sleeved on the first rotating shaft 221, and the second rotating wheel 224 and the second gear 226 are sleeved on the second rotating shaft 222. One end of the first rotating shaft 221 away from the side wall is connected to the rotating shaft of the motor.

[0030] The hot air circulation tunnel sterilization oven 10 provided in this embodiment works as follows: Estimate the height of the material to be dried, turn on the motor, the rotation of the motor shaft drives the rotation of the first rotating shaft 221, which in turn drives the rotation of the first rotating wheel 223 and the first gear 225. The first gear 225 drives another first gear 225 to rotate in the opposite direction, which drives the rotation of another first rotating shaft 221, and thus drives the rotation of another first rotating wheel 223. The first rotating wheel 223 drives the second rotating wheel 224 to rotate through the conveyor belt 229, which drives the rotation of the second rotating shaft 222, and thus drives the reverse rotation of the two second gears 226. The second gears 226 drive the rack 228 to move up or down, which drives the front door cover 140 or the rear door cover 170 to move up and down to the specified position, so as to realize the simultaneous lifting and lowering of the front door cover 140 and the rear door cover 170 to adjust to the appropriate height for the material to pass through, reduce the inlet and outlet openings, and avoid bringing in too many external pollutants.
[0031] In summary, for the hot air circulation tunnel sterilization oven 10 provided in this embodiment, the hot air circulation tunnel sterilization oven 10 can realize the simultaneous lifting and lowering of the front door cover 140 and the rear door cover 170, so as to meet the requirements of bottles of different heights to enter and exit the drying section 110 of the oven, and at the same time avoid the entry of external pollution sources into the drying section 110 through the large opening of the drying section 110, which affects sterilization, and has a wide range of applications.
