The black, blue, red and yellow are four primary colors, so that the black ink nozzle group 21, the blue ink nozzle group 22, the red ink nozzle group 23 and the yellow ink nozzle group 24 are mutually combined by matching with computer color matching software and PLC motion control, and patterns and designs with different colors can be printed on the edge sealing strip.
Correspondingly, four residual ink recovery containers are arranged below the four groups of ink nozzle groups. The four remaining ink recovery tanks correspond to the black remaining ink recovery tank 41, the blue remaining ink recovery tank 42, the red remaining ink recovery tank 43, and the yellow remaining ink recovery tank 44, respectively.
The ink recovery device 4 further includes a sub-tank 45 and an ink pump. Each of the remaining ink recovery tanks corresponds to one of the sub ink tanks 45 and the ink pump. The ink pump transports ink in the main ink tank 46 to the corresponding sub ink tank 45, and the sub ink tank 45 communicates with the corresponding ink head set. The method can be used for independently recycling the residual ink with different colors, so that recycling can be realized, pollution and waste of ink are avoided, and zero-discharge ink is realized.
In one embodiment, the cross beam plate 12 is provided with a printing platform 6, i.e. the printing platform is arranged below a number of ink jet groups. The printing platform and the residual ink recovery containers are integrally formed. Thereby being convenient for processing and installing the residual ink recovery container. The opening of the residual ink recovery container is rectangular, and the length direction of the residual ink recovery container is perpendicular to the moving direction of the edge sealing strip.
In one embodiment, a plurality of proximal stoppers 37 are disposed at intervals on both sides of the printing platform 6 in the longitudinal direction. Specifically, the number of the proximal stoppers 37 is set according to the edge banding, and in this embodiment, four edge banding is processed at the same time, so that the number of the proximal stoppers 37 in this embodiment is five. The proximal stoppers 37 are arranged at intervals, a transport channel is formed between adjacent proximal stoppers 37, and the edge sealing strip moves in the transport channel. The proximal stopper 37 plays a role in spacing the edge banding so that when a plurality of edge banding are processed, the plurality of edge banding can be spaced apart from one another by a distance of one end.
In one embodiment, a first transition roller 38 and a first flat carriage 13 are provided on a side of the first driven roller 311 remote from the first drive roller 31. A second transition roller 39 and a second carriage 14 are provided on a side of the second driven roller 321 remote from the second drive roller 32. A plurality of distal limiting blocks 15 are arranged on the first flat carriage 13 and the second flat carriage 14. The number of the far-end limiting blocks 15 is the same as the number and the functions of the near-end limiting blocks 37, and the function of separating a plurality of edge sealing strips is achieved.
The working principle of this embodiment is that four edge banding passes through the first flat carriage 13 and the first transition roller 38 in sequence, then passes through the lower part of the first driven roller 311, then passes through between the first driven roller 311 and the first driving roller 31, is clamped by the first driving roller 31 and the first driven roller 311, then passes through the upper part of the first driving roller 31, then passes through the lower parts of the black ink jet head group 21, the blue ink jet head group 22, the red ink jet head group 23 and the yellow ink jet head group 24, then passes through the upper part of the second driving roller 32, then passes through between the second driving roller 32 and the second driven roller 321, is clamped by the second driving roller 32 and the second driven roller 321, then passes through the lower part of the second driven roller 321, and then passes through the upper part of the second transition roller 39 and the first flat carriage 13.
The edge banding can move below the black ink jet head group 21, the blue ink jet head group 22, the red ink jet head group 23 and the yellow ink jet head group 24 by controlling the rotation of the first driving roller 31 and the second driving roller 32, and the edge banding is jet-printed by the black ink jet head group 21, the blue ink jet head group 22, the red ink jet head group 23 and the yellow ink jet head group 24, and the black ink jet head group 21, the blue ink jet head group 22, the red ink jet head group 23 and the yellow ink jet head group 24 are controlled by computer color matching software, so that patterns with various colors and patterns can be jet-printed.
In the process of jet printing, the sprayed surplus ink is recovered by respective surplus ink recovery containers, the recovered surplus ink falls into the main ink barrel 46, then the ink in the main ink barrel 46 is conveyed to the auxiliary ink barrel 45 through the ink pump, the ink nozzle group is communicated with the auxiliary ink barrel 45, and then the ink is sprayed from the ink nozzle group, so that the recovery and the utilization of the surplus ink are realized.
According to the invention, the edge banding is transported in a conveyor belt-free mode by the mutual matching of the first driving roller 31, the first driven roller 311, the second driving roller 32 and the second driven roller 321, that is, when the edge banding is subjected to jet printing, the bottom of the edge banding does not drive a medium which moves, so that ink is not sprayed on the conveyor belt, and compared with the prior art, the cleaning of a moving medium (conveyor belt) is omitted, so that continuous production of the edge banding is realized, and the production efficiency of the edge banding is further improved.
Meanwhile, the corresponding residual ink recovery containers are arranged at the bottoms of the ink nozzle groups, so that the recovery of the residual ink is realized, the recycling of the residual ink is realized, and the ink recycling device has the advantages of no waste of ink and no pollution.
Embodiment 3 As shown in FIG. 6, the structure of the present embodiment is similar to that of embodiment 2, except that the ink curing devices 7 are correspondingly arranged in the direction along which the edge sealing strips move in the plurality of ink nozzle groups, and after the ink nozzle groups jet ink on the edge sealing strips, the ink on the edge sealing strips is cured and dried when passing through the ink curing devices. That is, the black ink head set 21, the blue ink head set 22, the red ink head set 23, and the yellow ink head set 24 are each provided with one black ink curing device 71, one blue ink curing device 72, one red ink curing device 73, and one yellow ink curing device 74, respectively. The ink curing device in this embodiment employs a UV lamp including an LED lamp and a mercury lamp, but the ink curing device includes, but is not limited to, a UV lamp.
Black ink curing device 71, blue ink curing device 72, red ink curing device 73, and yellow ink curing device 74. The ink on the edge banding strip can be quickly air-dried before the next spray printing, so that the spray printing effect is better.
The above-described embodiments are merely preferred embodiments of the present invention, and the present invention is not limited in any way, and other variations and modifications may be made without departing from the technical aspects set forth in the claims.
