Description

Technical Field

[0001] The utility model relates to the field of bamboo material processing equipment, in particular to a centering guide mechanism. Background Art

[0002] In the field of bamboo processing technology, since some bamboos have bitter knots on their surfaces, in order to ensure that the bitter knots after bamboo splitting are located on the surfaces of the upper and lower bamboos respectively to avoid splitting from the position of the bitter knots when splitting, the part with the bitter knots needs to be rotated before splitting, so that some bitter knots face upwards, while the corresponding other bitter knots face downwards. Currently, the position of the bitter knots needs to be adjusted before splitting, and after the adjustment is completed, it is sent to the splitting process for splitting, and the centering needs to be performed before splitting to ensure that the width of each bamboo piece after splitting is uniform.

[0003] The existing centering mechanism of the bamboo splitting machine is generally arranged at one end close to the bamboo splitting knife for centering before splitting. The bamboo is usually split by pushing the material so that the bamboo is continuously approached to the bamboo splitting knife to complete the splitting. However, the existing centering mechanism has a small contact area with the bamboo at the centering position, which easily causes the bamboo to shift in position during the splitting process, resulting in the problem of uneven size of the bamboo pieces after the bamboo is split.
