[0002] Long workpieces with U-shaped or I-shaped cross-sections are generally referred to as profiles. The raw profiles need to be cut into fixed lengths according to the designed dimensions. Existing production processes often use cutting machines, which use cylinders or other devices to propel a rotating grinding wheel or saw blade along a linear trajectory to cut the profiles. However, this requires manual measurement and positioning of the profile material. This manual measurement and positioning is not only inefficient but also lacks precision, impacting the quality and yield of the finished profiles. Utility Model Content

[0005] When the present invention is in operation, the rotating roller on the second conveyor frame conveys the longer raw material profile to the conveyor roller of the first conveyor frame. At the same time, under the action of the sprocket assembly, the output shaft on the rear side of the reducer drives the swing shaft to rotate, and the swing shaft drives the limit stop seat to rotate above the conveyor roller, so as to realize the length positioning of the profile on the conveyor roller from the end. The two positioning cylinders on both sides respectively position the left and right sides of the profile. The clamping cylinder presses the upper surface of the profile to position it by pressing the pressure block. The rear end of the profile is limited by the limit stop seat, and the front end of the profile extends between the first and second conveyor frames. The cutting machine cuts the profile part extending out of the first conveyor frame to a fixed length. The cut profile is transported backward to the material receiving area, and the raw material profile continues to be transported backward in a cycle for the next cutting. Compared with the prior art, the present invention has the beneficial effect of improving the efficiency and accuracy of profile cutting by continuously transporting the profile and cutting the profile to a fixed size, thereby improving the quality of the profile and increasing the output.

[0006] As a further improvement of the present invention, the first conveyor frame includes two symmetrical side brackets, each of which is fixed at the bottom to a plurality of support frames. The roller shafts at the left and right ends of the conveyor roller are respectively rotatably connected to the two side brackets.
