Description

TECHNICAL FIELD

[0001] The utility model belongs to printing technical field, concretely relates to a movable nozzle module platform. BACKGROUND

[0002] Traditional single pass nozzle module platform usually adopts fixed installation method, and nozzles are arranged along the printing width direction to form continuous printing area, and the structure is like the single pass digital inkjet printing machine multi-column nozzle fixing plate fine adjustment device disclosed in the utility model patent with the authorization announcement number CN205800514U, which comprises: a base plate, which is provided with a plurality of columns of holes, the columns are staggered and differ by an equal distance, a nozzle is installed in each hole, a fixing hole for fixing the fine adjustment device is formed in the base plate, and the nozzles are sequentially installed in the fixing holes.

[0003] The above-mentioned single pass nozzle module platform needs to install a nozzle array capable of covering the entire 1800mm width for a 1800mm printing device. However, in actual application, especially in the corrugated paper industry, the image distribution is mostly on the left side, the middle and the right side, and the two side edges often do not need to be printed. In this case, the traditional fixed nozzle installation method causes the nozzles on the two side edges and some parts in the printing area to be in a non-working state for a long time, which not only reduces the utilization efficiency of the nozzles but also increases the risk of nozzle clogging. In order to prevent nozzle clogging, regular ink pressing operations must be performed, which further increases the consumption of ink. UTILITY MODEL CONTENT

[0004] The utility model aims at providing a movable nozzle module platform to solve the problems of low nozzle utilization rate, high nozzle clogging risk and large ink consumption of the existing single pass nozzle module platform.

[0005] In order to achieve the above-mentioned purpose, the technical scheme of the utility model is as follows:

[0007] Preferably, the nozzle modules each comprise a moving platform, a driving motor, a nozzle mounting seat and a plurality of nozzle units, the moving platform is installed on the first straight rail through the linear motor, the lower surface of the moving platform is provided with a second straight rail perpendicular to the length direction of the cross beam, the nozzle mounting seat is connected to the corresponding second straight rail through sliding and connected to the corresponding driving motor, and the nozzle units are distributed on the corresponding nozzle mounting seat.

[0008] Preferably, the spray head monomers are arranged in a "pin" shape on the corresponding spray head mounting seat.

[0009] Preferably, the spray head mounting seat is stepped with the adjacent surface of other spray head mounting seats.

[0016] In order to further understand the content of the utility model, the utility model is described in detail in combination with examples, and the following examples are used to illustrate the utility model but not to limit the scope of the utility model.

[0017] Referring to the drawings Figure 1 The utility model relates to a movable spray head module platform, which comprises a cross beam 1 and a plurality of spray head modules 2, the bottom of the cross beam 1 is provided with a first linear track 3 arranged along the length direction (the printing width direction) of the cross beam, and the spray head modules 2 are respectively slidably connected to the first linear track through linear motors 4.

[0018] Each of the printhead module 2 comprises a moving platform 5, a driving motor 8, a printhead mounting base 7 and several printhead units 9, the moving platform 5 is installed on the first linear track 3 through the linear motor 4, the lower surface of the moving platform 5 is provided with the second linear track 6 perpendicular to the length direction (the printing length direction) of the crossbeam 1, the printhead mounting base 7 is slidingly connected on the corresponding second linear track 6 and connected with the corresponding driving motor 8, the adjacent surface of the printhead mounting base and other printhead mounting bases is in a stepped shape, and the printhead units 9 are distributed on the corresponding printhead mounting base 7 in a 'pin' shape.

[0019] In use, the position of the printhead module 2 is dynamically adjusted according to the image distribution on the paper, so that the printhead module 2 only works above the area needing printing, specifically: when the printing area covers the whole paper, the plurality of printhead modules 2 can be combined for printing, as shown in the figure, and the printing mode is the same as the conventional single pass printhead module platform; when the printing area does not cover the whole paper, the printhead modules 2 can be separated, as shown in the figure, or part of the printhead modules 2 are combined and part of the printhead modules 2 are separated, as shown in the figure, so that the printhead module 2 only works above the area needing printing. Figure 1 Figure 2 Figure 3 Each printhead module 2 realizes the printing of the corresponding area by driving the printhead mounting base 7 to move along the second linear track 6 once through the driving motor 8 when working.
