[0032] Working principle: During use, the preheated hemp fiber raw material is placed into the grinding chamber 601. The hydraulic rod 4 is activated, causing the upper pressure mold 501 to descend. Through the arrangement of the upper pressure mold 501 and the grinding chamber 601, the hemp fiber raw material is hot-pressed and formed. As the lifting plate 5 descends, the hook plate 8 automatically feeds into the rear end of the lifting rod 11. After completion, when the hydraulic rod 4 returns to its original position, it rises a short distance and then drives the lifting rod 11 to rise through the hook plate 8. When the lifting rod 11 passes through the L-shaped plate 17 and the push block 18, it pushes the formed hemp fiber... After the PVC-formed board is pushed out, the trapezoidal board 14 moves under the action of the irregular hole 15 and the sliding rod 16. The roller 24 causes the push rod 21 to rise, which makes the rear end of the push block 18 rise faster, causing the hemp fiber-formed board to slide forward and place the prepared collection frame in front of the worktable 1 for automatic unloading, avoiding manual removal from the grinding cavity 601. When the stop rod 801 contacts the U-shaped rod 12, the hook plate 8 tilts. At this time, the lifting rod 11 returns to its original position with the push block 18 under the action of gravity, waiting to work again.
