The printer comprises a frame 7, a mounting platform 10, a beam 2, a printing trolley 3 and a conveying device, wherein the mounting platform 10 is horizontally and fixedly mounted on the frame 7. As shown in fig. 5 and 6, the conveying device includes a conveying frame 1 and a plurality of first conveying rollers 4, the conveying frame 1 is arranged horizontally, the conveying frame 1 includes two support plates 8 arranged in parallel, the two support plates 8 are vertically mounted on a mounting platform 10, a printing medium conveying channel is formed between the two support plates 8, and the printing medium is conveyed along the conveying channel (i.e. the conveying channel is in the conveying direction of the printing medium).

The plurality of conveying rollers are arranged between the two supporting plates 8 and are uniformly distributed along the conveying direction of the printing medium, the axes of the conveying rollers are parallel to each other, and the included angle alpha between the projection of the axes of the conveying rollers in the horizontal direction and the projection of the supporting plates 8 in the horizontal direction is 90 degrees; the both ends of each conveying roller are rotated respectively and are installed on two backup pads 8, and one end of each conveying roller passes one of them each backup pad 8, pass one of them backup pad 8 at each conveying roller and serve and install driven sprocket 9, each driven sprocket 9 all connects on same chain, the other end of this chain is connected with the action wheel, this action wheel is driven by the motor, loop through action wheel and chain drive respectively from the driving wheel rotation after the motor output shaft rotates for each conveying roller synchronous rotation.

The beam 2 is horizontally disposed above the transport frame 1, the beam 2 and the transport direction of the printing medium are parallel to each other, and both ends of the beam 2 are mounted on the frame 7, and the mounting structure of the beam 2 and the frame 7 is well known to those skilled in the art and will not be described in detail herein. 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 synchronously rotate through the output shafts, the driving wheel and the chain, and the first conveying rollers 4 synchronously rotate 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:

s1, moving the beam to a position above the first printing medium (when the printer is in an initial state, the beam is at the non-printing position, and the beam is far away from the transmission device, as shown in FIG. 8; step S1, moving the beam from the non-printing position to printingAfter the medium is over, the beam is at the print station and is close to the transport device, as shown in fig. 4), and the time taken by the beam is t₁The sliding stroke of the corresponding cross beam is S₂；

Especially in the printing production process of the production lineExample 1 shortens (Nt) when the number of printing media is (N +1)₂+Nt₄+Nt₅) Thereby remarkably improving printing efficiency, embodiment 1 shortens (NS)₂+NS₄+NS₅) Thereby significantly reducing the energy consumption of the device.

Meanwhile, the inkjet printer in embodiment 1 conveys the printing medium in the manner of the first conveying roller, so that the smoothness of conveying the printing medium is improved, and the printing medium can be conveyed to a correct printing position, thereby improving the printing effect of the pattern on the printing medium.

The moving speed V of the cross beam in the existing flat-panel printer₁Is lower than the moving speed V of the printing trolley 3₂This in turn requires a longer time for the beam to move over the print media, which also results in less efficient printing by the apparatus. In the embodiment 1, the moving distance of the beam is greatly shortened, and the printing efficiency is improved from another aspect. The manner in which the printing medium is conveyed 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 baffle 5 is provided with a plurality of through holes 11 through which the first transport rollers 4 pass, and the through holes 11 are uniformly distributed along the transport direction of the printing medium.
