Detailed Description of the Embodiments

[0018] The following further elaborates in detail on the specific embodiments of the present utility model. Figure 1-2

[0019] By Figure 1-2 ​Provided is a dryer for plastic bottle production according to the present utility model, which includes a drying box 10. A rotating disk 20 is rotatably arranged inside the drying box 10. Limiting rods 30 are fixed on the surface of the rotating disk 20. The limiting rods 30 are used to limit the plastic bottles. The specific usage method is to put the bottle mouth down on the limiting rods 30. A plurality of supporting members 40 are fixed on the lower side surface of the limiting rods 30. The supporting members 40 are used to support the plastic bottles. After being supported by the supporting members 40, there will be a certain gap between the lower end of the plastic bottle and the surface of the rotating disk 20, which facilitates the water inside the plastic bottle to flow out. The drying box 10 is equipped with a rotating mechanism 50 for driving the rotating disk 20 to rotate. By driving the rotating disk 20 to rotate through the rotating mechanism 50, under the action of centrifugal force, the water on the surface of the plastic bottle can be thrown off. Further, in order to accelerate the drying of the plastic bottle, the inside of the limiting rod 30 is hollow and through holes 31 are provided on the side surface. A hot air head 60 for introducing hot air into the limiting rod 30 is installed on the surface of the rotating disk 20. The hot air head 60 is connected to a hot air blower 61. During the rotation of the rotating disk 20, the hot air blower 61 works to generate hot air, and the hot air is blown into the plastic bottle through the hot air head 60, which is convenient for drying the inside of the plastic bottle. In addition, due to the setting of the supporting members 40, the hot air inside the plastic bottle will also flow out through the gap at the lower end of the plastic bottle and gradually fill the drying box 10, drying the outer wall of the plastic bottle.

[0020] The supporting member 40 can be any one of a rectangle, a circle, and a triangle. In this embodiment, the supporting member 40 is preferably a triangular sheet structure, and the number of the supporting members 40 is 2-4. The triangular structure can support the bottle mouth and play a simple limiting role.

[0021] In order to improve the dehydration effect of the plastic bottle when the rotating disk 20 rotates, the lower end of the limiting rod 30 is inclined outward. It can be understood that when the rotating disk 20 rotates, it drives the plastic bottle to rotate around the center of the rotating disk 20, and a centrifugal force is generated during the rotation. This centrifugal force makes the water on the inner wall of the plastic bottle move away from the center of the rotating disk 20, and the lower end of the limiting rod 30 is inclined outward, so that the water on the inner wall of the plastic bottle flows downward along the inner wall of the plastic bottle when moving away from the center of the rotating disk 20, thereby accelerating the discharge from the bottle mouth.

[0022] A rotating shaft 21 is fixed to the rotating disk 20. The lower end of the rotating shaft 21 is rotatably connected to the bottom of the drying box 10. The rotating mechanism 50 includes a motor 51 fixed inside the drying box 10, a gear 52 fixed to the output shaft of the motor 51, and a gear ring 53 fixed to the rotating shaft 21. The gear 52 is meshed with the gear ring 53. When the external power supply of the motor 51 is connected, the output shaft of the motor 51 drives the gear 52 to rotate, the gear 52 drives the gear ring 53 to rotate, the gear ring 53 drives the rotating shaft 21 to rotate, and the rotating shaft 21 rotates to drive the rotating disk 20 to rotate.

[0023] The inside of the rotating shaft 21 is hollow and its lower end penetrates through the drying box 10. The hot air blower 61 is installed at the lower end of the drying box 10. A connecting pipe 62 is provided at the air outlet of the hot air blower 61. The connecting pipe 62 is connected to the rotating shaft 21 through a rotary joint 63. During operation, the hot air blower 61 generates hot air, which is sent into the inside of the rotating shaft 21 through the connecting pipe 62, and then sent into the hot air head 20 through the rotating shaft 21. It enters the limiting rod 30 through the hot air head 20 and is ejected from the through holes on the side of the limiting rod 30 to dry the inner wall of the plastic bottle.

[0024] An air inlet pipe 64 is connected to the air inlet of the hot air blower 61. A circulation pipe 65 is connected between the inside of the drying box 10 and the air inlet pipe 64. A humidity sensor 66 is connected to the circulation pipe 65. The hot air blower 61 replenishes new dry air through the air inlet pipe 64, and the dry air is sent into the drying box 10 after being heated by the hot air blower 61. The hot air in the drying box 10 will return to the air inlet pipe 64 again through the circulation pipe 65. The humidity sensor 66 is used to detect the humidity of the air in the circulation pipe 65.

[0025] The drying box 10 is provided with an exhaust pipe 70 for discharging the humid air in the drying box 10 to the outside.

[0026] Solenoid valves 80 are provided on the air inlet pipe 64, the circulation pipe 65 and the exhaust pipe 70. At the beginning, air is introduced through the air inlet pipe 64. When there is enough hot air in the drying box 10, the air intake volume of the air inlet pipe 64 can be gradually reduced, and the hot air is circulated through the circulation pipe 65. When the humidity of the air in the circulation pipe 65 is relatively high, the circulation pipe 65 is closed, the exhaust pipe 70 is opened to discharge the hot and humid air, and dry air is replenished through the air inlet pipe 64 again.

[0027] A dryer for plastic bottle production of the present utility model supports and limits the plastic bottle through the inclined limiting rod 30 and several supporting members 40 fixed at the bottom of the limiting rod 30, so that when the rotating disk 20 rotates, the water on the inner surface of the plastic bottle can be better thrown out through the bottle mouth. Through the settings of the circulation pipe 65, the exhaust pipe 70 and the humidity sensor 66, the dry hot air can circulate between the drying box 10, the circulation pipe 65 and the hot air blower 61, reducing energy waste, and when the humidity sensor 66 detects that the humidity inside the circulation pipe 65 is relatively high, the wet air can be discharged through the exhaust pipe.

[0028] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments or perform equivalent replacements for some of the technical features. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
