The invention relates to the field of aluminum profile
machining equipment, in particular to an automatic
cutting machine of an aluminum profile. The automatic
cutting machine comprises a feeding conveying table, a discharging conveying table, a quantitative limiting device, an ejection device and a transmission device; the feeding conveying table comprises a feeding conveying belt, the discharging conveying table is provided with a discharging conveying belt, the quantitative limiting device comprises a positioning component and a
cutting component, the positioning component is provided with a positioning
assembly, and the cutting component is located between the feeding conveying belt and the discharging conveying belt and is provided with a cutting
assembly; and the transmission device is provided with a conveying
assembly, and the ejection device is arranged between the output end of the feeding conveying belt and the input end of the discharging conveying belt and is located below the cutting device. According to the automatic cutting
machine, the automatic feeding, cutting, ejection and discharging manner is adopted, manpower output is reduced, and the working efficiency of cutting operation is improved; and accurate grasping on the to-be-
cut aluminum profile position is achieved through a sensing component, and the method is high in working efficiency, accurate in cutting size and high in uniformity of products.
