Similarly, the upper film 5 drives the rotary gluing piece 42 to rotate clockwise, and the rotary gluing piece 42 uniformly adheres the adhesive to the surface of the upper film 5. When the upper film material 5 rotates along with the nip roll 41 to contact with the lower film material 6, the upper film material 5 and the lower film material 6 are bonded and pressed by the nip roll 41, and then the seed film covering is completed. The belt 12 is continuously driven forward in this process. Finally, the seed film after the film covering is rolled by the rolling tension of the rolling shaft 13.

The row spacing can be accurately controlled by PLC control, and the plant spacing can be accurately controlled by adjusting the positions of the seed sucking and releasing mechanism 3 and the die stamping mechanism 2. The matrix hole array can make the seeds germinate and smoothly root the soil.

The storability of the seed film is greatly improved, the seed film can be processed in advance, the working time is increased under the condition of not influencing the farming season, and a film spreading machine which only performs simple rotary motion can be used for replacing a transplanter with a complex mechanism.
