The alignment electric slide rail, in conjunction with the lifting and lowering of the cooperating frame and support platform, enables continuous printing. A flip motor drives the flip processing frame to rotate, changing the air intake angle of the cooling fan to directly cool the printing contact area. This achieves printing cooling. The bidirectional air intake counter-current reduces material misalignment caused by unilateral direct airflow, improving production stability. The cooling fan exhausts air outwards, while external air intake is achieved through cooling fixing holes and a processing mesh cage. This internal and external air intake circulation controls the internal ambient temperature, improving printing stability and speed. Attached Figure Description

[0042] To ensure stable operation of the equipment, the input terminals of the alignment electric slide rail 201, linkage electromagnet 205, cooling cooler 208, circulating pump 211, and fitting electric slide rail 212 are all electrically connected to the output terminal of an external power supply.

[0043] The printing limit box 1 is equipped with a mating component 3 inside;

[0044] The supporting component 3 includes a horizontal electric slide rail 301, a translation processing box 302, a translation electric slide rail 303, a print head 304, a flip motor 305, a flip processing frame 306, a cooling fan 307, a cooling fixing hole 308, and a processing mesh cage 309.

[0045] A horizontal electric slide rail 301 is installed at the top of the inner side of the printing restriction box 1. A translation processing box 302 is installed at the bottom of the horizontal electric slide rail 301 through a slide rail seat. The translation processing box 302 is slidably installed inside the printing restriction box 1 to realize the displacement support and positioning restriction.

[0046] A translational electric slide rail 303 is installed at the bottom of the translational processing box 302, and a print head 304 is installed at the bottom of the translational electric slide rail 303 via a slide rail seat.

[0047] Both ends of the printhead 304 are equipped with a flip motor 305 via a motor mount. The output shaft of the flip motor 305 is snapped with a flip processing frame 306.

In conjunction with the alignment electric slide rail 201, the lifting and lowering frame 202 and the support platform 206 are raised and lowered to achieve continuous printing. At this time, the flip motor 305 drives the flip processing frame 306 to rotate along the print head 304, changing the air intake angle of the cooling fan 307 to directly cool the printing contact position, thus achieving printing cooling. At this time, the cooling fan 307 exhausts air outward. The external air is blocked and restricted by the processing mesh cage 309 and enters the inside of the printing restriction box 1 through the cooling fixing hole 308, achieving direct cooling of the inside and improving the stability and speed of printing.
