A furniture board grinding device

Abstract

The invention discloses a furniture board grinding device. The angle oscillating mechanism of the invention can drive the grinding mechanism to vibrate, so that the grinding belt of the grinding mechanism can be polished in the left and right directions, and the grinding running direction of the grinding belt can be well controlled. The included angle with the left and right directions of the workbench changes within a certain angle range to prevent the abrasive belt from scratching the surface of the plate due to pressure changes during the previous period of grinding and the subsequent period of grinding when the abrasive belt is grinding the plate The grinding pressure control mechanism of the present invention adopts the pressure belt to carry out compression, and while the pressure belt applies the pressure towards the direction of the belt grinding plate to the grinding mechanism, the pressure belt also moves with the grinding mechanism, effectively ensuring the contact between the abrasive belt and the plate during compression. Surface contact, the pressure belt can be set as a rough structure with protrusions, which is convenient for the grinding belt to drive it to move together, to ensure grinding efficiency, and to prevent friction and energy loss caused by the relative movement between the pressure belt and the abrasive belt.

Description

technical field [0001] The invention relates to the field of furniture board processing, in particular to a furniture board grinding device. Background technique [0002] At present, the furniture plate grinding device on the market generally uses a grinding belt for grinding. When the ordinary grinding belt is polished, the edge of the grinding belt and the surface of the workpiece are often prone to large grinding marks during the grinding process, resulting in The surface of the board is not bright, and after the subsequent painting, the grinding marks are very obvious. Moreover, the grinding belt is generally pressed on the surface of the board with a pressing wheel, which leads to a line contact between the belt and the board during pressing, and the grinding efficiency It is not high, and the grinding accuracy is difficult to control, and it is easy to produce over-polished parts or under-polished parts. It is difficult to ensure the flatness of the board, which affect...
