A second conveyor belt 9 is installed between the third rotating shaft 5, the fourth rotating shaft 6, the fifth rotating shaft 7 and the sixth rotating shaft 8, and the second conveyor belt 9 bypasses the bottom of the second rotating shaft 3, that is, the first conveyor belt 4 extends downward to the middle position of the second conveyor belt 9, and the first conveyor belt 4 contacts the second conveyor belts 9 on both sides to form a conveying and turning channel for the film material.

[0019] The first conveyor belt 4 contacts the second conveyor belt 9 on the side of the fourth rotating shaft 6 to form a feeding channel, and the first conveyor belt 4 contacts the second conveyor belt 9 on the side of the third rotating shaft 5 to form a discharging channel. Driven by the friction of the second conveyor belt 9, the third rotating shaft 5, the fourth rotating shaft 6, the fifth rotating shaft 7 and the sixth rotating shaft 8 can rotate synchronously in the same direction, wherein the first rotating shaft 2 and the fourth rotating shaft 6 can rotate synchronously in the opposite direction, that is, the first conveyor belt 4 and the second conveyor belt 9 rotate synchronously in the opposite direction, so that the film material between the two conveyor belts can move and turn over by squeezing and clamping each other.
