Example

[0018] Please see Figure 1 and Figure 2 The following technical solution is provided, specifically disclosed: A battery box 15 is fixedly connected to the outer side of the frame 3 by bolts, and a storage battery 14 is fixedly connected to the inner cavity of the battery box 15 by bolts. A charging port 16 is opened at the middle of one side of the battery box 15, and the output end of the charging port 16 is unidirectionally electrically connected to the input end of the storage battery 14. A display 6 is fixedly connected to the top of the outer side of the constant temperature oil tank 8 by bolts. A temperature sensor 7 is fixedly connected to the bottom of one side of the constant temperature oil tank 8 by bolts. The output end of the temperature sensor 7 is unidirectionally electrically connected to the input end of the display 6. A pressure sensor 20 is fixedly connected to the bottom of the gas tank 13 by bolts. The output end of the pressure sensor 20 is unidirectionally electrically connected to the input end of the display 6. An auxiliary roller 9 is fixedly connected to the middle of the left and right sides of the frame 3 by bearings. A rubber ring is provided on the surface of the auxiliary roller 9. A PLC controller 17 is fixedly connected to the upper end of the outer side of the frame 3 by bolts. The output end of the PLC controller 17 is unidirectionally electrically connected to the input ends of the electric telescopic rod 5, the oil pump 2 and the fan 12. In practical use, a circulating constant-temperature system is formed by the constant-temperature oil tank 8, oil pump 2, and circulation pipeline 4. Oil pump 2 circulates the oil in the constant-temperature oil tank through the circulation pipeline, ensuring stable temperature between the fixed roller 11 and the movable roller 19 during calendering. Stable temperature helps improve the calendering quality of PTFE material and avoids changes in material properties due to temperature fluctuations. The electric telescopic rod 5 can move the movable plate 18 and the movable roller 19 up and down, thereby changing the distance between the movable roller 19 and the fixed roller 11. This allows for flexible adjustment of the calendering thickness according to the processing requirements of the PTFE air filter element, meeting the production requirements of different specifications of products.

[0019] In use: Charge the battery 14 through charging port 16, add an appropriate amount of oil to the constant temperature oil tank 8, and inflate the gas tank 13. The operator sets the extension length of the electric telescopic rod 5 and adjusts the distance between the movable roller 19 and the fixed roller 11 according to the processing requirements of the PTFE air filter element via the PLC controller 17. Start the oil pump 2, which draws oil from the constant temperature oil tank 8 and circulates it through the circulation pipe 4. The temperature sensor 7 monitors the oil temperature in real time and transmits the data to the display 6. If the oil temperature is abnormal, the constant temperature oil tank can be adjusted accordingly to ensure the oil temperature remains stable within a suitable range. Start the fan 12, which transports the gas from the gas tank 13 to the frame 3 through the pipe, and the gas is discharged from the exhaust port 10. The air pressure sensor 20 monitors the air pressure in the gas tank in real time and transmits the data to the display 6. If the air pressure is insufficient, replenish the air in time to ensure ventilation. Place the PTFE material on the auxiliary roller 9, and the material enters between the movable roller 19 and the fixed roller 11 with the assistance of the auxiliary roller. The electric telescopic mast 5 applies pressure, causing the movable and fixed rollers to calender the material. During calendering, the ventilation system operates continuously, removing dust and heat. In the event of a power outage, the battery 14 automatically supplies power to the electric telescopic mast 5, oil pump 2, and fan 12, ensuring continued operation for a period of time and preventing production interruptions. Operators can monitor and control the operation of the electric telescopic mast 5, oil pump 2, and fan 12 throughout the process via the PLC controller 17. Simultaneously, parameters such as oil temperature and air pressure can be viewed in real time on the display 6 to ensure stable equipment operation and product quality.
