At the same time, starting the servo motor (8) drives the belt (9) and the pulley (10), one of the pulleys (10) drives the feeding roller (4) to rotate, and the other pulley (10) drives the winding roller (30) to rotate, and the bamboo fibers on the outer wall of the feeding roller (4) can be wound on the outer wall of the winding roller (30); S4: simultaneously starting the rotating motor (25) to drive the bidirectional screw (24) to rotate, so that one end of the squeezing plate (21) can be threadedly connected to the bidirectional screw (24), so that the two squeezing plates (21) can drive the squeezing rollers (22) to move until they are attached to both sides of the bamboo fiber. When the bamboo fiber moves, it can be squeezed to squeeze out the moisture contained in the bamboo fiber; S5: Start the lifting cylinder (29) to drive the extrusion plate (27) to rise, so that the extrusion plate (27) can fit the bottom of the bamboo fiber, thereby further extruding the bamboo fiber, and the excess water will pass through the screen (28) and fall into the inner cavity of the device body (1). The water in the inner cavity of the device body (1) can be discharged by opening the drain pipe (2); S6: After all the bamboo fibers are wound onto the outer wall of the winding roller (30), the servo motor (8) is started in reverse, so that the bamboo fibers on the outer wall of the winding roller (30) can be rewound onto the outer wall of the feeding roller (4), thereby repeatedly drying the bamboo fibers through the blowing fan (5), the electric heating wire (6), and the extrusion plate (21). After drying, the dried bamboo fibers can be unloaded from the feeding roller (4).
