Description

Technical Field

[0001] The utility model relates to the technical field of wood processing, in particular to a device for grinding corners of wooden boards of wooden packaging boxes. Background Art

[0002] Wooden packaging boxes are wooden boxes used for packaging. There is no specific regulation on their size. Generally, they are determined according to specific requirements and are mainly made of four wooden boards. Wooden packaging boxes are widely used for their strength, convenient material acquisition, moisture resistance and other advantages.

[0003] The existing (Announcement No.: CN213673317U) discloses a wood edge and corner grinding device, which fixes a wooden board on an operating table. Under the action of a slider and a slide groove, the wooden board can be easily moved, so that the wooden board can be fixed according to the required grinding requirements. Under the action of a bearing and a shaft rod, people can rotate the wooden board conveniently so that the four corners of the wooden board can be evenly grinded, avoiding manual hand-held wood grinding, effectively avoiding poor wood grinding effect, and at the same time reducing the work danger of the staff, facilitating the control of the wood edge and corner grinding device, reducing the difficulty of people grinding the wood edges and corners, and meeting people's needs.

[0004] However, the three corner surfaces of the same side of the wooden board need to be polished (the upper, lower and side surfaces of the corner), so the above patent ignores this problem, resulting in incomplete polishing of the wooden board corners. Secondly, waste chips will be generated during the polishing process of the wooden board, which will affect the operating environment in the long run and endanger the inhalation health of the staff.
