Description

Technical Field

[0001] This invention relates to the field of manufacturing technology for chamfering edge banding strips for wooden boards, and in particular to a device for automatically adjusting the chamfering angle of the upper and lower chamfering of edge banding strips for wooden tabletops. Background Technology

[0002] As people's living standards improve, the requirements for wooden furniture are becoming increasingly higher. Beyond durability, higher demands are being placed on safety and aesthetics. In the manufacturing process of wooden furniture, edge banding strips need to be applied to the sides of the wooden panels.

[0003] Initially, edge banding was applied manually. However, with the promotion of automated factories, automatic edge banding machines have emerged. For example, Chinese patent CN205021353U discloses a device for chamfering the upper and lower edges of artificial edge banding. This device includes a frame with a conveying mechanism for horizontally conveying trimmed artificial boards. A bracket is located next to the conveying mechanism on the frame, and a vertical screw and vertical guide posts on its left and right sides are mounted on the bracket. An upper slide and a lower slide, which can be adjusted up and down along the vertical guide posts, are fitted on the vertical screw. An upper motor base is connected to the front end of the upper slide, and an upper motor that tilts left and right is mounted on the upper motor base. An upper grinding wheel for grinding and chamfering the upper edge of the edge banding is mounted on the output shaft at the upper end of the upper motor. A lower motor base is connected to the rear end of the lower slide, and a lower motor that tilts left and right is mounted on the lower motor base. A lower grinding wheel for grinding and chamfering the lower edge of the edge banding is mounted on the output shaft at the lower end of the lower motor. The chamfering device in this patent can adapt to the width and thickness of the engineered wood panel and can simultaneously chamfer the top and bottom edges, resulting in high efficiency.

[0004] However, as the factory's manufacturing scope expands, it needs to manufacture wooden tabletops with different beveling angles. If the beveling device in the aforementioned patent is used, firstly, manual adjustment is required, affecting the manufacturing pace; secondly, different models of machines need to be purchased directly, increasing the factory's cost investment.
