According to the automatic unloading and spreading machine according to claim 1, the wheel seat of the driven wheel is in the shape of ㄇ, and the transverse rod of the wheel seat is passed through the perforation of the base of the fifth adjustment component. According to claim 1 or 10 of the automatic feeding and spreading machine, the base of the fifth adjustment component is installed on the third guide rod, and a handle is provided above the base, and the handle can be released by loosening the handle. The base can be moved left and right on the third guide rod to adjust the position and position; the base is provided with perforations, which can be passed through by the transverse rod of the wheel base, and an elastic element is arranged under the transverse rod, and is corresponding to the aforesaid An adjustment element is arranged above the perforation, and the central axis of the adjustment element extends into the transverse rod of the wheel base. The quick-adjusting wheel can quickly adjust the up and down movement distance of the central axis to adjust the position of the driven wheel and change the distance or gap between the driven wheel and the first conveyor belt of one of the first conveying components to match the thickness of the object. According to the automatic unloading and spreading machine according to claim 1, the air chamber of the second conveying component is connected to an external air pump by a pipeline. According to the automatic feeding and spreading machine described in claim 1, the air chamber air holes of the air chamber are preferably elongated holes; the conveyor belt air holes of the second conveyor belt are preferably circular holes to prevent airflow from entering the air chamber. The problem of leakage occurs before the air hole, resulting in the problem of insufficient vacuum suction. According to the automatic unloading and spreading machine according to claim 1, an inkjet printer is installed on the sixth adjustment component, and the sixth adjustment component is installed on the fourth guide rod, so that the inkjet printer can be installed on the fourth guide rod. The fourth guide rod is moved and adjusted left and right by the sixth adjustment component, and is positioned to match the position of the text, number or pattern to be printed on the object; the fourth guide rod is guided by more than one guide rod. The guide rod is composed of a guide rod, and the two sides of the guide rod are combined with the fourth rod seat, and then the fourth rod seat is installed on the chassis component.
