Description

Technical Field

[0001] The utility model relates to the technical field of furniture processing, in particular to a cutting machine. Background Art

[0002] Furniture is made of various materials through a series of technical processing. Materials are the material basis of furniture. Therefore, in addition to the basic requirements of functionality, aesthetics and craftsmanship, furniture design is also closely related to materials. Most of the existing furniture is made of wood. Wooden furniture needs to be cut during processing. Cutting machines are commonly used cutting equipment.

[0003] A Chinese patent discloses a wood cutting machine for furniture processing (authorization announcement number CN217225867U), and its specification discloses that "starting the electric telescopic rod drives the connecting plate to move vertically, the connecting plate drives the square column to move, the square column drives the mounting plate to move, and the mounting plate drives the limiting roller to move vertically, so that the limiting roller presses the surface of the plate to avoid shaking when the plate is cut. Under the action of the compression spring, it is convenient to protect the surface of the plate to avoid excessive downward pressure of the electric telescopic rod driving the limiting spoke to move, causing damage to the surface of the plate and affecting the use effect." However, according to common knowledge, since the compression spring has a certain elasticity, when the high-speed rotating saw blade contacts the plate, the force acting on the plate at this time will be transmitted to the compression spring, and cause a certain deformation of the compression spring. At this time, the plate is prone to swing to a certain extent, which is likely to cause problems such as substandard cutting quality. Utility Model Content

After the motor 45 is powered on, it can drive the saw blade 46 to rotate, and when the electric push rod 412 extends, it can drive the rotating saw blade 46 to continuously move backward. At this time, both ends of the first placement rack 47 slide on the two second placement racks 48 respectively. At this time, through the continuous backward movement of the rotating saw blade 46, the plate can be cut.
