Description

Technical Field

[0001] The invention relates to the technical field of bamboo skewer polishing, in particular to a bamboo skewer polishing machine. Background Art

[0002] Bamboo sticks refer to objects made of bamboo or wood that are cut and processed into slender shapes. The two ends are usually smooth or sometimes sharpened. They are used as tools for piercing, fixing or decoration. The shape of bamboo sticks can be straight, or it can be spiral, wavy or other special designs. It is suitable for fixing some small foods, such as small meatballs, shrimps, vegetable pieces, etc. The spiral bamboo sticks can provide additional support due to their spiral shape. These foods are not easy to slip during the baking process, and are easier to flip and bake evenly. When making spiral bamboo sticks, the surface of the bamboo sticks is generally polished by a grinding drill to drill out a threaded groove. After the groove is drilled, the surface of the bamboo stick is polished.

[0003] In the prior art, when polishing a spiral bamboo stick, the surface of the bamboo stick is generally polished by hand-held sandpaper, and then the spiral groove on the surface of the bamboo stick is polished by a brush or a polishing air bag.
