[0038] Through the above scheme: by arranging a lifting mechanism 9 and two adjusting mechanisms on the upper part of the base plate 1, the nozzle 12 in the device is located at the lower part of the second adjusting mechanism 11.

[0039] In this embodiment, the protective cover 6 includes a transparent cover 61, and the rear right end and the rear left end of the transparent cover 61 are movably connected to movable doors 62, the front end of the transparent cover 61 is fixedly connected to a control panel 63 and is provided with a plurality of air inlet holes 64, the rear end of the transparent cover 61 is provided with a connecting hole 65, the transparent cover 61 is fixedly connected to the bottom plate 1, the dust suction component 7 includes a dust collector 71, the input end of the dust collector 71 is fixedly connected to a fixed pipe 72, the front end of the fixed pipe 72 is fixedly connected to a suction nozzle 73, the output end of the dust collector 71 is fixedly connected to a dust storage box 74, the dust collector 71 and the dust storage box 74 are both fixedly connected to the rear of the protective cover 6, the fixed pipe 72 is interlaced with the connecting hole 65, and the suction nozzle 73 is located inside the protective cover 6.

[0040] Through the above scheme: by providing a protective cover 6 on the upper part of the base plate 1 and providing a dust suction component 7 at the rear of the protective cover 6, when the device is in use, the protective cover 6 can protect other components used for printing operations in the device to prevent printing failure caused by foreign objects touching the device during operation.

This design not only realizes the recycling of resources and reduces waste, but also greatly simplifies the cleaning process of the device, providing great convenience for subsequent use.
