Description

Technical Field

[0001] This utility model relates to a chamfering mechanism, specifically a medium fiberboard chamfering mechanism, belonging to the field of board chamfering technology. Background Technology

[0002] Medium-density fiberboard (MDF) is a type of engineered wood product made from wood fibers, formed under high temperature and pressure with synthetic resin adhesives. It has a uniform internal structure, a smooth surface, and is easy to process, making it commonly used in furniture manufacturing, decorative finishing, and audio equipment. MDF possesses good physical properties and stability, and is easy to carve, glue, and paint; however, it has poor moisture resistance and easily swells when exposed to water, requiring use in a dry environment or moisture-proofing treatment.

[0003] Medium-density fiberboard (MDF) is commonly used in custom furniture manufacturing due to its smooth surface and ease of processing, making it highly favored by the furniture industry. However, due to varying customization needs and different board thicknesses, existing equipment struggles to quickly adjust the chamfering depth and adapt to different board thicknesses, reducing work efficiency. Therefore, this paper proposes a MDF chamfering mechanism. Utility Model Content

The height adjustment component 3 includes an adjustment sleeve 301, a sliding plate 302 and a moving rod 303. The adjustment sleeve 301 and the sliding plate 302 are fixed together, and the moving rod 303 is fixed on the adjustment sleeve 301.

[0026] Please refer to this carefully. Figure 1 , Figure 2 and Figure 3 The adjusting sleeve 301 is provided with an interface 304, which can be connected to an industrial vacuum cleaner to collect the dust generated during the chamfering process and avoid affecting the workers. A guide rod 305 is fixed on the adjusting sleeve 301. The guide rod 305 is slidably connected to the housing 101, and the upper end of the guide rod 305 extends into the housing 101.

[0027] Please refer to this carefully. Figure 2 and Figure 4 The moving rod 303 is mounted on the housing 101 via the driving component 4. The driving component 4 includes a connecting plate 401, which is fixed to the moving rod 303. A positioning rod 408 is slidably connected to the connecting plate 401.

[0028] Please refer to this carefully. Figure 2 and Figure 4 The positioning rod 408 is fixed inside the housing 101. The positioning rod 408 serves to guide the connecting plate 401. The connecting plate 401 can slide on the positioning rod 408. A slider 402 is fixed on the connecting plate 401. A lead screw 403 is installed inside the slider 402.
