The material grabbing mechanism 2 is arranged above the feeding frame 11 and comprises a grabbing part 21 used for clamping the left side and the right side of the bamboo strip, a lifting power part 22 driving the grabbing part 21 to vertically move and a material grabbing seat 23 used for fixing the lifting power part 22.

The grabbing part 21 is a pneumatic clamping jaw, and the clamping width of the pneumatic clamping jaw is slightly smaller than the width of the bamboo strips.

The feeding mechanism 3 comprises a feeding driving component 31 for driving the grabbing mechanism 2 to do arc motion in the front-back direction.

The arc motion comprises a lifting arc at the rear section and a descending arc (such as an arch) at the front section, and the material grabbing mechanism 2 firstly lifts upwards and then descends in the process of moving from back to front.

The lifting movement is used to assist the drawing of the bamboo strips, and the lowering movement is used to return, the grip portion 21 can be moved up to get around the bamboo strips in the drawing operation.

When the material grabbing mechanism 2 grabs, the grabbing part 21 generally grabs the front section part of the bamboo batten on the uppermost layer, and the rear section part of the bamboo batten is easy to be pressed on the lower layer or the bamboo joints on the lower layer are clamped on the adjacent bamboo joints due to stacking, so that the feeding mechanism 3 is blocked in the front and rear feeding processes.

In the process that the material grabbing mechanism 2 is driven by the feeding mechanism 3 to move from the rear side material grabbing station to the front side material loading station, a lifting pulling action is provided, so that the condition of material feeding blocking can be effectively avoided.
