Description

Technical Field

[0001] This utility model relates to the field of pencil processing technology, and in particular to a pencil board grooving machine. Background Technology

[0002] In the pencil production process, a pencil board grooving machine is used to create multiple narrow grooves on a wooden board to hold the pencil lead. Existing pencil board grooving machines require conveyor rollers to press the board firmly during grooving. The board is then transported through a conveyor trough to the grooving assembly for grooving. During this process, the sides of the board are restrained by the conveyor trough to prevent skewing. However, the conveyor troughs of existing pencil board grooving machines can only restrain boards of a fixed width, and cannot be used for boards of different widths. This results in overly wide boards not being able to pass through the conveyor trough, or overly narrow boards skewing during transport, leading to poor grooving quality. Utility Model Content
