As shown in fig. 11, in the embodiment, the conveying direction of the first conveying device 1100 is perpendicular to the conveying direction of the second conveying device 1200, the feeding end of the second conveying device 1200 is opposite to the discharging end of the first conveying device 1100, the discharging end of the first conveying device 1100 conveys the printing medium 1000 to the feeding end of the second conveying device 1200, and the storing device 1300 is arranged below the discharging end of the second conveying device 1200. As shown in fig. 10, the discharging end of the first conveyor 1100 is located at a predetermined height of the feeding end of the second conveyor 1200. The preset height is a height difference between the conveying surface of the first conveying device 1100 and the conveying surface of the second conveying device 1200 in the vertical direction in this embodiment, and is 200mm in this embodiment; therefore, the printing medium 1000 conveyed on the first conveyor 1100 falls from the discharge end of the first conveyor 1100 into the feed end of the second conveyor 1200, and the printing medium 1000 is conveyed further by the second conveyor 1200 and falls from the discharge end of the second conveyor 1200 into the stocker 1300 for collection.

The first stopping member 1211 is located on a side of the second conveying device 1200 away from the first conveying device 1100, and the first stopping member 1211 is located on a side of the second conveying device 1200 away from the first conveying device 1100. Since the first stopping member 1211 is located on a side of the second conveying device 1200 away from the first conveying device 1100, in a process that the printing medium 1000 conveyed on the first conveying device 1100 falls into a feeding end of the second conveying device 1200 from a discharging end of the first conveying device 1100, the printing medium 1000 makes a parabolic motion, and mainly the first stopping member 1211 stops the printing medium 1000 from falling from the second conveying device 1200. Therefore, in this embodiment, the height of the first stopping member 1211 is set to be lower than the preset height by 40mm to 60mm, and specifically, the height of the first stopping member 1211 is 150mm, so that the printing medium 1000 can be stopped from falling from the second conveying device 1200, the height of the first stopping member 1211 can be reasonably controlled, and waste of materials caused by the fact that the first stopping member 1211 is too high is avoided.

As shown in fig. 11, a second blocking mechanism 1110 is provided on the first conveyance device 1100, and the second blocking mechanism 1110 is used to block the printing medium 1000 from falling from the first conveyance device 1100 during the conveyance of the printing medium 1000 by the first conveyance device 1100. In this embodiment, the second material blocking mechanism 1110 includes a third material blocking member 1111 and a fourth material blocking member 1112, the third material blocking member 1111 and the fourth material blocking member 1112 are respectively disposed on two opposite sides of the second conveying device 1200 along the fourth direction, the third material blocking member 1111 and the fourth material blocking member 1112 are respectively disposed on two opposite sides of the first belt along the fourth direction, and the fourth direction is perpendicular to the conveying direction of the first conveying device 1100. In this embodiment, the second blocking member 1212, the third blocking member 1111, and the fourth blocking member 1112 only need to prevent the printing medium 1000 from falling off from the conveying device in the process, and therefore the heights of the second blocking member 1212, the third blocking member 1111, and the fourth blocking member are greater than or equal to the height of the printing medium 1000.

As shown in fig. 10, in the present embodiment, the width of the printing medium 1000 is smaller than the length of the printing medium 1000, for example, the printing medium 1000 is a remote controller, and a pattern is printed on a housing of the remote controller. In the present embodiment, the conveying direction of the first conveying device 1100 is parallel to the width direction of the printing medium 1000, and the conveying direction of the second conveying device 1200 is parallel to the length direction of the printing medium 1000. While the width S2 of the second conveyor 1200 in the fifth direction is smaller than the width S1 of the first conveyor 1100 in the fourth direction. After the printing medium 1000 is fed onto the first conveying device 1100, as shown in fig. 10, the conveying direction of the first conveying device 1100 is parallel to the width direction of the printing medium 1000, the conveying direction of the second conveying device 1200 is parallel to the length direction of the printing medium 1000, and because the width of the printing medium 1000 is smaller than the length of the printing medium, the width of the first conveying device 1100 in the fourth direction is set to be matched with the length of the printing medium 1000, and the width of the second conveying device 1200 in the fifth direction is reduced, so that the width of the second conveying device 1200 can be matched with the width of the printing medium 1000, and the requirement for conveying the printing medium 1000 is met; and reducing the width of the second conveyor 1200 in the fifth direction reduces the size of the printing apparatus, thereby facilitating packaging and transportation.

Example 5

As shown in fig. 17, the inkjet printing apparatus according to embodiment 5 of the present invention is modified from embodiment 2 to embodiment 4. Specifically, in the present embodiment, the conveying direction of the first conveying device 1100 is not perpendicular to the conveying direction of the second conveying device 1200, but the conveying direction of the first conveying device 1100 is inclined to the conveying direction of the second conveying device 1200. In the present embodiment, the conveying direction of the first conveying device 1100 and the width direction of the printing medium 1000 are inclined to each other, and the conveying direction of the second conveying device 1200 is parallel to the length direction of the printing medium 1000. After the printing medium 1000 is fed onto the first conveying device 1100, as shown in fig. 17, the conveying direction of the first conveying device 1100 is inclined to the width direction of the printing medium 1000, the conveying direction of the second conveying device 1200 is parallel to the length direction of the printing medium 1000, and because the width of the printing medium 1000 is smaller than the length of the printing medium 1000, the width of the first conveying device 1100 in the fourth direction is set to meet the conveying requirement of the printing medium 1000, and meanwhile, after the width of the second conveying device 1200 in the fifth direction is reduced, the width of the second conveying device 1200 can also be matched with the width of the printing medium 1000, so that the requirement of conveying the printing medium 1000 is met; and reducing the width of the second conveyor 1200 in the fifth direction reduces the size of the printing apparatus, thereby facilitating packaging and transportation.

Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; such modifications and substitutions do not depart from the spirit and scope of the present invention.
