[0030] See Figure 6 , the synchronous pulley transmission mechanism 2 adopted by the present utility model includes a transmission member, a transmission shaft 207 and a fixed support; the transmission shaft 207 is arranged inside the forming chamber box body 5 through the fixed support; the drive mechanism 1 is connected to the transmission shaft 207 through the transmission member and drives the transmission shaft 207 to rotate; the first multi-link mechanism and the second multi-link mechanism are respectively arranged at both ends of the transmission shaft 207; the transmission shaft 207 drives the flap 308 to rotate around the axis of the transmission shaft 207 through the first multi-link mechanism and the second multi-link mechanism respectively. Exemplarily, the transmission member may include a driving synchronous pulley 201, a fixing ring 204, a synchronous belt 202 and a driven synchronous pulley 205; the driven synchronous pulley 205 is sleeved outside the transmission shaft 207 and is connected to the transmission shaft 207 through a key and is fixed to the driven synchronous pulley 205 through the fixing ring 204 to prevent the driven synchronous pulley 205 from axially moving along the transmission shaft 207; the synchronous belt 202 is wound around the driving synchronous pulley 201 and the driven synchronous pulley 205; the drive mechanism 1 drives the driving synchronous pulley 201 to rotate; the driving synchronous pulley 201 drives the transmission shaft 207 to rotate around the axis of the transmission shaft 207 through the synchronous belt 202 and the driven synchronous pulley 205.

The drive shaft 207 drives the second connecting rod 302 to rotate, and the second connecting rod 302 drives the movement of the remaining connecting rods through the rotating shaft pin 305, thereby driving the flip cover 308 to flip up and down, and finally realizing the opening or closing of the forming width 6. See Figure 1 , in the retracted state of the flip cover 308, when the forming cylinder 4 is ready, after the power of the motor 104 passes through the reducer 105 and the synchronous belt 202, it drives the flip cover 308 to slowly retract counterclockwise along the established track of the connecting rod for normal equipment printing; see Figure 8 , in the state where the flip cover falls: after printing is completed and the printed part moves down below the substrate, at this time, the motor 104 drives the connecting rod to rotate clockwise through the reducer 105, thereby driving the flip cover 308 to slowly lower until it covers the forming width 6 and is airtight, and then the parts of the forming cylinder can be removed.
