The printing trolley 3 is slidably mounted on the cross beam 2, namely the reciprocating sliding direction of the printing trolley 3 on the cross beam 2 is parallel to the conveying direction of the printing medium, and the moving direction of the printing trolley during ink-jet printing is parallel to the conveying direction of the printing medium; since the sliding connection of the carriage 3 to the cross member 2 is well known to those skilled in the art, it will not be described in detail here.
As shown in fig. 7, the operation principle of the printer in embodiment 1 is as follows (also taking printing five packing boxes as an example, the length, width and height of each packing box are 20cm, 20cm and 10cm respectively, and the packing boxes are used for packing fresh products such as live fish and live shrimp): the motor rotates, the output shafts are driven to rotate synchronously through the output shafts, the driving wheel and the chain, and the conveying rollers 4 rotate synchronously to sequentially drive the five packing boxes to move along the conveying direction of the medium, so that the five packing boxes are placed on the conveying frame 1 (the arrangement direction of the five packing boxes is the same as the sliding direction of the printing trolley 3). Then the printing trolley 3 slides on the beam 2 to print the five packing boxes; the printing steps of the printing trolley 3 are as follows:

The mode of conveying the printing medium by the conveying device also improves the efficiency of conveying the printing medium to the printing area.

Example 3:
as shown in fig. 9 to 12, the printer according to embodiment 3 of the present invention is modified from that of embodiment 1. Specifically, the printer in embodiment 3 further includes a first limit baffle 5 and a second limit baffle 6, where the first limit baffle 5 and the second limit baffle 6 are both parallel to the conveying direction of the printing medium, and the first limit baffle 5 and the second limit baffle 6 are both perpendicular to the mounting platform 10. The first limit baffle 5 is arranged between two supporting plates 8, and the lower end of the second limit baffle 6 is fixedly arranged on one supporting plate 8. As shown in fig. 13 and 14, the first limit fence 5 is provided with a plurality of through holes 11 through which the feed roller 4 passes, and the through holes 11 are uniformly distributed in the feed direction of the printing medium. The plane opposite to the second limiting baffle 6 on the first limiting baffle 5 is set as a first limiting plane, the plane opposite to the first limiting baffle 5 on the second limiting baffle 6 is set as a second limiting plane, and the first limiting plane and the second limiting plane are parallel to the conveying direction of the printing medium.
In this embodiment, the first limit baffle 5 is connected in the following two ways:
the first connection mode is that the lower extreme fixed connection of first limit baffle 5 is on mounting platform 10 (if the welding), and on the direction of motion of crossbeam this moment, the distance between first limit plane and the second limit plane is preset distance, and the size of this preset distance matches each other with the size of packing box on the crossbeam direction of motion (for example when the size of packing box on the crossbeam direction of motion is 20cm, preset distance establishes to 20.5cm, because there is the error in the size of packing box, has set up 0.5 cm's surplus, guarantees that the packing box can pass smoothly).
The second connection mode is that the first limit baffle 5 is installed on the installation platform 10 in a movable mode along the movement direction of the cross beam, namely, an adjusting mechanism for adjusting the position of the first limit baffle 5 is arranged on the installation platform 10.

Two sliding holes 13 are arranged on the mounting platform 10, the sliding holes 13 are waist-shaped holes, the length directions of the two sliding holes 13 are parallel to the moving direction of the cross beam, the distance between the two sliding holes 13 is equal to the distance between the two bolt mounting holes 12, and one sliding hole 13 corresponds to one bolt mounting hole 12. After the bolt 15 passes through the corresponding first sliding hole 13 and one bolt mounting hole 12, the mounting plate 14 is connected with the mounting platform 10, and after the bolt 15 is screwed down through a nut, the mounting plate 14 is fixed with the mounting platform 10.
