The printing plate of the circular screen printer is cylindrical, the circular screen printer directly adopts a guide belt, the printing speed is high and can reach 5000m per hour, but the circular screen printer only can print fixed patterns, is suitable for grey cloth produced in batch and has a narrow application range. The printing plate of the flat screen printing machine is a planar screen printing plate, and the cloth feeding of the flat screen printing machine is provided with a guide belt and a bedplate. The flat screen printing machine is called a circular or oval printing machine, is suitable for various printing materials, such as mucilage, water paste, printing ink and the like, and has a wide application range.

A novel printing machine with small occupied area and a large number of table plates is provided with a three-dimensional feeding frame and a three-dimensional discharging frame, wherein two groups of vertical feeding or discharging mechanisms and a horizontal direction adjusting mechanism for connecting the two groups of vertical feeding or discharging mechanisms are arranged on the three-dimensional feeding frame and the three-dimensional discharging frame. Taking the vertical feeding mechanism as an example, feeding chains rotating in the vertical direction are installed on two sides of the vertical feeding mechanism in the vertical direction, a plurality of feeding supporting pieces are installed on the non-sprocket sides of the feeding chains, and the printing bedplate supports the feeding supporting pieces on two sides. The feeding chain is driven by the transmission mechanism to drive the printing table plate to move in the vertical direction. When the automatic printing machine works, the printing table plate moves vertically from bottom to top under the action of the vertical feeding mechanism and then is transferred to the other vertical feeding mechanism by the horizontal direction adjusting mechanism to move from top to bottom. Although the novel printing machine with the structure increases the number of the table plates in unit area and improves the yield, the novel printing machine still has certain problems: two sets of perpendicular feed mechanism on three-dimensional advance, ejection of compact frame adopt the chain structure, and the chain can't accomplish two sets of perpendicular feed mechanism paces unanimously completely when the drive stamp platen, and after the accumulation error, the level is transferred to the perpendicular feed mechanism stamp platen height at mechanism both ends and is not at same horizontal plane, causes the level to transfer to the unable smooth handing-over stamp platen of mechanism, consequently has great problem in the aspect of above-mentioned structural reliability, stability.
