The structural arrangement of the unfolding wing 14 is not only beneficial to the separation of the ramie strips after splitting, but also convenient to flatten the separated ramie strips.
The working process is as follows: after the forwardly conveyed ramie strips contact the positioning tip 11, the positioning tip 11 moves along the hollow structure of the ramie strips due to the hollow structure of the ramie strips, the trend of the ramie strips is controlled, the guide is provided for advancing of the ramie strips, the self-centering function of the cutter is realized, and the ramie strips move along the axial direction of the positioning tip 11. Under the guiding effect of location point 11, the ramie strip contacts with the cutting edge 121 of connecting at location point 11 rear portion, and cutting edge 121 splits the ramie strip from the upside, forms small-angle split mouth, and the quality of split ramie dissection is influenced to the angle of cutting edge 121, and knife face 122 plays the effect of supplementary direction on the vertical direction. The guiding function of the flared shape formed by the upper cover 21 and the lower U-shaped body 22, the positioning tip 11 and the knife surface 122 ensures that the ramie strips are quickly aligned and slide along the axial direction of the positioning tip 11, so that the ramie strips are quickly split and unfolded along the axial direction on one side. The boat-shaped splitting head 13 gradually increases the splitting angle of the split ramie strips, and the ramie strips split by a certain angle enter the part of the unfolding wing 14 at the rear end of the combined cutter, so that the split ramie strips are gradually unfolded to a flat state. The height of the flat rectangular space at the rear end of the combined cutter in the embodiment is 8mm, and the split ramie strips are unfolded and laid on one side by the flat rectangular space to be in a state that the ramie core faces upwards and the phloem faces downwards, so that conditions are provided for stripping the ramie core in the next step.
The principle and the implementation mode of the invention are explained by applying a specific example, and the description of the embodiment is only used for helping to understand the method and the core idea of the invention; meanwhile, for a person skilled in the art, according to the idea of the present invention, the specific embodiments and the application range may be changed.
