PLC automatic control steel drum screen printing machine

Patent Application No. X

The utility model relates to the technical field of printing machinery, in particular to a PLC automatic control steel drum screen printing machine. A plurality of parallel positioning positioning rollers are arranged on the upper surface of the machine seat, and a positioning block is arranged on the frame on the back side of the machine base with the positioning rollers. The screen plate is located above the positioning roller, and is connected to a guide rail of a sliding seat through a screen plate fixing frame. The sliding block is movably sleeved on the frame, and the sliding carriage is controlled by a driving mechanism. A squeegee is mounted above the screen, and the squeegee is driven by a cylinder. The power mechanism of the screen printing machine is controlled by a PLC controller. After adopting such a structure, the steel drum is placed on the positioning roller. The roller is supported on the lower side of both sides of the steel drum, and one end of the steel drum is pressed against the positioning block to position the steel drum. The positioning is simple and reliable. When the steel drum is printed, the roller can be rotated along with the horizontal movement of the screen to ensure the uniformity of the printing, and the steel drum is subjected to uniform force. The printed graphic is clear and does not adhere.
