The movable die moves towards the die holder to convey the previous working procedure to the arc-shaped bamboo chips on the die holder, and the arc-shaped bamboo chips are pressed and flattened through extrusion, so that the bamboo chips are shaped in a heat preservation mode. However, in the process of pressing the arc-shaped bamboo chips, the existing pressing equipment does not pre-tighten the arc-shaped bamboo chips in the length direction for use or clamping, so that the arc-shaped bamboo chips are frequently cracked or over-pressed, the thickness of the formed straight bamboo chips is difficult to control, and more cracks exist, so that the obtained bamboo chips have the following defects:

firstly, the bamboo chips have large fiber damage, poor toughness and low resistance capability.

Secondly, the bamboo chips are not beautiful due to the appearance of the bamboo chips, and the glue amount for treating the cracks on the bamboo chips is increased (namely, the cracks on the bamboo chips are treated by glue), so that the cost is increased.

Thirdly, the qualified rate of the formed straight bamboo chips is low, and the production requirements of enterprises cannot be met.

Fourthly, the width directions of the flattened bamboo chips are uneven, so that the materials are not convenient to arrange (namely, the edges of the redundant bamboo chips need to be cut off for trimming), the waste of the bamboo chips is caused, and the cost is increased.

In view of the above, the present inventors have conducted extensive studies on existing pressing apparatuses and have made the present invention.
