The discharge roller 20 of the printer is used for discharging the unprinted printed substrate, and the receiving roller 150 is used for collecting the printed substrate after printing.

Referring to fig. 1, first, by disposing the discharging roller 20 outside the frame 10, an operator can replace and disassemble the printing substrate 60 at the outside. And the discharging roller 20 is arranged at the outer side relative to the two guide rollers, so that the printing substrate 60 can bypass the two guide rollers in the frame 10, and the influence of factors such as external error touch or wind power on the flattening of the printing substrate 60 is avoided.

Secondly, since the discharging roller 20 is usually disposed at the lower side of the frame 10, if the discharging roller 20 is far away from the second guide roller 40, and the printing substrate 60 on the discharging roller 20 directly passes through the second guide roller 40, the flattening effect of the printing substrate 60 between the discharging roller 20 and the second guide roller 40 is easily reduced, so that the printing substrate 60 has obvious wrinkles under gravity or other factors, which may increase the difficulty of flattening the printing substrate 60 by the second guide roller 40, and even when the second guide roller 40 is flattened, the conveying direction of the printing substrate 60 is inclined. By arranging that the printing substrate 60 firstly bypasses the first guide roller 30, and the distance between the two guide rollers is smaller than the distance between the first guide roller 30 and the discharging roller 20, the extension length of the printing substrate 60 between the two guide rollers is shorter, so that the printing substrate 60 is less affected by factors such as gravity, and the like, and therefore, the printing substrate 60 is not easy to wrinkle, and the printing substrate 60 is beneficial to flattening; meanwhile, when the distance between the two guide rollers is small, the tensioning effect on the printing base material 60 is good, and the printing base material 60 can advance according to the original conveying direction due to the good tensioning effect.

More importantly, in the horizontal direction, the second guide roller 40 is disposed between the first guide roller 30 and the discharging roller 20, and meanwhile, after the printing substrate 60 on the discharging roller 20 bypasses the first guide roller 30 which is relatively far away, the printing substrate 60 bypasses the side of the second guide roller 40 close to the discharging roller 20 and then extends to the printing platform 50, so that the printing substrate 60 and the two guide rollers have a larger contact area, thereby enabling the printing substrate 60 to have a better holding effect on the guide rollers, further enabling the flattening and guiding effects of the guide rollers on the printing substrate 60 to be more stable and accurate, enabling the printing substrate 60 to be kept in a flattened state when being conveyed to the upper side of the printing platform 50, and facilitating printing.

With continued reference to fig. 1, the second guide roller 40 is further optimized in that the second guide roller 40 is a screw-thread flattening roller, and after the printing substrate 60 is well flattened and guided during the conveying process, the printing substrate 60 is flattened again by the screw-thread flattening roller, so that the printing substrate 60 between the second guide roller 40 and the printing platform 50 is more flat. The first guide roller is a rubber roller or a metal roller, and the holding force between the first guide roller and the printing substrate can be increased in the process of conveying the printing substrate, so that the printing substrate can be always close to the first guide roller to be conveyed, and the conveying is more accurate and stable.
