Description

Technical Field

[0001] The invention relates to the technical field of bamboo product milling processing, in particular to processing equipment and a processing method for bamboo bottle caps. Background Art

[0002] Bamboo is a plant that grows very fast. It is highly renewable and easily degradable. Therefore, bottle caps made of bamboo are more environmentally friendly instead of traditional plastic ones.

[0003] In the prior art, in the shape of a bamboo bottle cap used for food storage bottles, its main body is in the shape of a flat rotating body with a step structure on its side. The lower step is provided with an annular groove for connecting the sealing rubber ring. When in use, the upper step covers the bottle mouth, and the sealing rubber ring connected to the lower step is interference fit with the inner side of the bottle mouth. In the existing process of the above-mentioned bamboo bottle cap, a flat bamboo board is used as the base material, and a CNC milling machine is used to cut the flat bamboo board into two sizes of circular plates. The two sizes of circular plates are coaxially fitted to form a stepped bottle cap shape, and then the bottle cap is clamped on the milling machine. An annular groove is milled on the side edge of the lower step for connecting the sealing rubber ring. This processing method requires many steps and is complicated. In addition, the process of gluing the two sizes of circular plates to each other is prone to errors, making it difficult to achieve complete coaxiality, thereby affecting the sealing performance of the bottle cap covering the bottle mouth, and easily leading to a large amount of scrap being wasted.

[0076] Step 6: Control the XZ dual-axis moving module 7 to drive the turning and milling tool 8 downward and move in the X direction to separate from the bamboo round rod 9;

[0077] Reference Figure 5 and Figure 8 Step 7: Control the lifting cylinder 62 to drive the saw blade 61 to move downward, and cut the bamboo round rod 9 at the position of the chamfer 111, so that the cut-off part forms the shape of a bamboo bottle cap.
