[0029] Specifically: The inside of the driven rotating cylinder 207 can be engaged with the tooth grooves of the driving gear 210 and used in cooperation. When the driving gear 210 rotates, it can drive the driven rotating cylinder 207 to rotate.

[0035] Specifically: The second motor 304 is fixed to the surface of the motor plate 205 to prevent the shaking of the second motor 304 during operation from affecting the normal use of this molding machine.

[0036] Working principle: Connect this pulp molding container forming machine to an external power supply device. The external power supply device is electrically connected to the electric cylinder 104, the first motor 211, the heating rod 301, the temperature sensor 302, and the second motor 304 to provide power. The control terminal 101 is electrically connected to the electric cylinder 104, the first motor 211, the heating rod 301, and the second motor 304 for associated control. The temperature sensor 302 can monitor the temperature of the heat-conducting oil 305 inside the pressing block 201 in real time and send a signal to the control terminal 101. The temperature of the heat-conducting oil 305 sent by the temperature sensor 302 is displayed on the surface of the control terminal 101 in real time. Set the drying temperature through the control terminal 101 and start the heating rod 301 and the second motor 304. The heating rod 301 heats the heat-conducting oil 305, and the output end of the second motor 304 drives the temperature sensor 302 to rotate to stir the heat-conducting oil 305, making the heat-conducting oil 305 evenly heated. When the temperature monitored by the temperature sensor 302 is lower than the set drying temperature, the heating rod 301 continuously heats the heat-conducting oil 305. When the temperature monitored by the temperature sensor 302 is greater than or equal to the set drying temperature, the control terminal 101 controls the heating rod 301 to be turned off. Such a setting enables precise control of the surface temperature of the pressing block 201, avoiding damage to the pulp molding container when the pressing block 201 presses down due to excessive local temperature. Place the pulp molding container to be dried and formed inside the mold cavity 102. When the temperature displayed on the control terminal 101 reaches the set drying temperature, set the pressing-down duration through the control terminal 101 and start the electric cylinder 104 and the first motor 211. The electric cylinder 104 extends, and the pressing block 201 moves into the mold cavity 102 to dry and form the pulp molding container. The output end of the first motor 211 drives the rotating shaft 209 to rotate, driving the driving gear 210 to rotate accordingly. The driving gear 210 drives the driven rotating cylinder 207 to rotate, and the cutting knife 208 cuts the surface of the top of the excess pulp molding container. Such a design eliminates the need for manual corner correction by workers, reducing the labor intensity of workers. After reaching the set time, the electric cylinder 104 shortens, and the formed pulp molding container can be taken out.
