The light emitted from the curing mechanism 42 is arranged in parallel with the inclined surface 431.

Preferably, the connecting base 43 is provided with a plurality of rows of waist-shaped holes 432 penetrating the inclined surface 431, and the length direction of the waist-shaped holes 432 is perpendicular to the plumb direction.

In the present embodiment, each row of the waist-shaped holes 432 includes a plurality of waist-shaped holes 432 arranged at intervals, and the length direction of the waist-shaped holes 432 extends along the arrangement direction; the connecting base 43 can adjust the relative position relationship between the connecting base 43 and the curing mechanism 42 along the length direction of the waist-shaped hole 432, that is, the relative position relationship between the curing mechanism 42 and the printing module 4 body in the width direction can be adjusted through the waist-shaped hole 432 on the inclined surface 431. A plurality of rows of waist-shaped holes 432 are formed in the vertical surface of the connecting seat 43 away from the inclined surface 431, and the length direction of each row of waist-shaped holes 432 is parallel to the plumb direction. The height relative position of the printing module 4 body and the connecting seat 43 is adjusted through the waist-shaped hole 432 on the vertical surface, and then the relative height position relation of the curing mechanism 42 and the printing module 4 body is adjusted. The positional relationship of the curing mechanism 42 with respect to the body of the print module 4 in the height direction and the width direction is adjusted from the waist-shaped holes 432 on both side surfaces.

Preferably, as shown in fig. 7, the print module 4 includes a protection cover 44, the protection cover 44 is disposed on a side surface of the body of the print module 4, and forms a protection cavity with the side surface, and the curing mechanism 42 is accommodated in the protection cavity.

In this embodiment, the protective cover 44 is provided to prevent the light emitted from the curing mechanism 42 from being emitted to other places and causing damage to other equipment mechanisms or the human body.

Preferably, the acute angle of the light emitted from the curing mechanism 42 with respect to the direction in which the liquid is ejected from the ejection head 45 is set to 3 ° to 5 °.

In this embodiment, it is avoided that the light inclination angle of the curing mechanism 42 is too high, which results in the light not being irradiated in place, and the inclination angle is also avoided being low, and a part of the light is reflected to irradiate the nozzle 45, which results in invalid installation. Preferably set at 4.

Preferably, the print module 4 includes a plurality of nozzles 45, and the plurality of nozzles 45 are seamlessly spliced along the scanning direction.

In this embodiment, each nozzle 45 is configured as a seamless joint, so that the influence of the air flow on the middle nozzle 45 in the scanning process of the nozzle 45 is reduced, and ink flying is further caused. And the seamless splicing of the plurality of spray heads 45 is convenient for controlling the printing of the whole printing module 4.

Preferably, the print module further includes a fixing member, and the fixing member is provided with a fixing portion for fixing the nozzles 45, so that the adjacent nozzles 45 are fixed to the fixing member.

In this embodiment, the fixing member is configured as the bottom surface of the print module body 41, and the two ends of the nozzles 45 are fixed to the fixing member by screws or the like, so that each nozzle is seamlessly spliced and fixed to the fixing member.

Finally, it should be noted that: the above embodiments are only used for illustrating the technical solutions of the present application, and not for limiting the same; while the utility model has been described in detail and with reference to the foregoing embodiments, it will 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; and the modifications or the substitutions do not make the essence of the corresponding technical solutions depart from the scope of the technical solutions of the embodiments of the present invention.
