However, this method usually requires a long processing time, and the automation degree of the equipment is relatively low, often requiring manual intervention. Especially in mass production, the drying and conveying of bottles are often separate processes, and the connection between processes is not tight enough, which easily leads to the stagnation of the production line and reduces the overall production efficiency. For this reason, we propose a sterile drying oven for PE bottles. Content of the Utility Model

The first cylinder extends under the instruction of the control unit, driving the second cylinder and the servo motor to move towards the position where the PE bottles are located. When the telescopic end of the second cylinder approaches the PE bottle, the second cylinder starts to work to further adjust the position of the clamping jaws so that they can accurately clamp the PE bottles. After the clamping jaws clamp the PE bottles, the first cylinder and the second cylinder work together to lift the PE bottles from the storage box and move them above the conveyor belt. The servo motor rotates according to the instruction of the control unit, driving the clamping jaws and the PE bottles to flip, ensuring that the mouths of the PE bottles face downward, and then accurately sleeving the mouths on the moving air blowing pipe. The air compressor provides sterile air, which is conveyed through the connecting pipe into the cavity of the conveyor belt, and the sterile air in the cavity then enters the PE bottles through the air blowing pipe for drying treatment. During the continuous operation of the conveyor belt, the air blowing pipe moves forward with the drying PE bottles. When the air blowing pipe reaches the end of the conveyor belt, the dried PE bottles will automatically fall off the air blowing pipe and enter the next process. As the conveyor belt moves in a cycle, new air blowing pipes are sent into the drying area, and at the same time, new PE bottles are clamped and flipped by the clamping and flipping mechanism and sleeved on the air blowing pipe. The whole process circulates without manual intervention, ensuring the continuity and high efficiency of the production line. Description of the Drawings

Through the precise control of the cylinder and the servo motor 11, the clamping and flipping mechanism can accurately grab the PE bottle 6 and complete the flipping action to ensure that the bottle mouth is accurately sleeved on the air blowing pipe 2.
[0020] The air blowing pipe 2 is of a conical structure, and the diameter of the air blowing pipe 2 is smaller than the diameter of the mouth of the PE bottle 6, ensuring that the air can be concentrated and penetrate deep into the bottle.
[0021] The air compressor 4 contains sterile air, ensuring that no pollutants enter the bottle during the drying process and maintaining the sterility of the drying environment.
[0022] An air flow regulating valve 17 is provided between the air blowing pipe 2 and the connecting pipe 3 to control the size of the air flow entering the air blowing pipe 2, ensuring that the air flow during the drying process adapts to different bottle specifications and drying requirements.
