Description

Technical Field

[0001] The invention relates to the technical field of furniture board cutting, and in particular to a cutting and feeding device for furniture board. Background Art

[0002] Most of the boards on the market are large rectangular flat boards with a size of 1.2m*2.4m*0.18m. Large solid wood flat boards are heavier due to their abundant materials. To make furniture with solid wood boards, you need to cut them to get the desired shape and size. However, solid wood boards are relatively thick and large in size. There are currently two ways to cut boards. One is to drive the board close to the cutting machine and cut it, and the other is to hold the cutting machine by hand to cut the board. The way to get the board close to the cutting machine is generally to push it manually. There are risks in this process. For example, when the manpower is not as strong as the cutting torque, the board will be displaced, which will also cause hand injuries. Of course, hydraulic rods will be used to drive the board close to the cutting, but when the board contacts the cutting machine, the tail end of the board will vibrate. Without a pressing component, the board will bounce and displace, which will eventually lead to inaccurate cutting of the board. Summary of the invention
