[0026] In this utility model:

[0027] First, the geotextile is moved forward by the matching motion of two rollers 6. The operator controls the motor 4, which drives the drive shaft 5 to rotate the turntable 24. The turntable 24 drives the slide rail 33 via the slider 26. The slide rail 33, slider 26, and turntable 24 form an eccentric wheel assembly. The slide rail 33 drives the slider 29 on the slide rod 25 via the reciprocating rod 32. The back-and-forth movement of the slider 29 drives the correcting roller 31 to reciprocate through the long rod 30. The correcting roller 31, through the friction between its multiple sets of correcting rods 39 and the geotextile, and the back-and-forth oscillation, can smooth out the wrinkles in the geotextile, eliminating the need for manual wrinkle smoothing. As the geotextile continues to move forward, the control motor 4 can also drive the rotating shaft 8 via two bevel gears 9. The rotating shaft 8 drives the rotating shaft 11 via bevel gear 12. The rotating shaft 11 drives the rotating shaft 13 via the pulley assembly 14. The rotating shaft 13 drives the fixed block 16 to rotate via the turntable 15. The fixed block 16 is threadedly connected to the slider 17 via the threaded rod 18, which in turn drives the turntable 19 to rotate. Because the slider 20 is restricted by the bracket 2, the rotation of the turntable 19 can drive the slider 20 to slide up and down within the bracket 2, thereby driving the needle-punching plate 22 to needle the geotextile. When it is necessary to adjust the needle-punching depth, the threaded rod 18 is turned, which causes the slider 17 to slide downward, thereby causing the center of the turntable 19 to move away from the center of the turntable 15, achieving an eccentric wheel structure. This increases the range of motion of the needle-punching plate 22, completing the adjustment of the needle-punching depth of the geotextile by the needle-punching plate 22. This can be done without disassembling the entire machine for adjustment, making the whole process time-saving, labor-saving, and highly intelligent. After the needle-punching is completed, the drive motor 34 drives the turntable 36 to rotate via the rotating shaft 35, thereby winding and collecting the geotextile.
