Wherein the guiding mechanism 200 is arranged on the feeding machine body 100 at intervals for guiding the movement of the section bar, the feeding mechanism 300 is arranged above the guiding mechanism 200 at intervals, the feeding mechanism 300 can move in the vertical direction relative to the feeding machine body 100, and the feeding mechanism 300 can provide downward pressure for the section bar and push the section bar to move along the guiding mechanism 200. The speed measuring mechanism 400 is disposed at the entrance of the feeding body 100 for measuring the moving speed of the profile. The conveying roller 110 is embedded in the feeding body 100, and the controller is electrically connected to the feeding mechanism 300 and the speed measuring mechanism 400 respectively, receives the speed information fed back by the speed measuring mechanism 400, and controls the feeding mechanism 300 to operate according to the speed information.

Since the feeding of the profile is subject to varying resistance during the machining of the profile, such as cold bending or grinding, the static friction between the profile and the feeding mechanism 300 needs to be increased accordingly in order to ensure that the profile does not slip during the feeding. In the above technical scheme, when the controller detects that the movement speed of the profile is less than the linear speed provided by the feeding mechanism 300, the controller controls the feeding mechanism 300 to descend to provide a larger downward pressure for the profile, so as to increase the static friction force between the feeding mechanism 300 and the profile, and avoid the influence on the processing of the profile caused by the slippage of the profile in the feeding process.
