[0021] See also Figures 1 to 4 The utility model provides a technical solution: a printed part air circulation cooling device, comprising a 3D printer 1, a printing platform 3 is fixedly arranged at the bottom of the inner side of the 3D printer 1, a storage bin 6 is opened at the bottom of the printing platform 3 corresponding to the bottom end of the 3D printer 1, a refrigeration mechanism is arranged inside the storage bin 6, and the refrigeration mechanism includes a semiconductor refrigeration sheet 7, cooling mechanisms 4 are arranged on both sides of the printing platform 3 through hydraulic rods 12, and the cooling mechanism 4 includes a fixed plate 13, and the fixed plate 13 is fixedly arranged on the top of the output rod of the hydraulic rod 12, and a nozzle 14 is fixedly arranged at one end of the fixed plate 13, and the shape of the printing platform 3 is "U"-shaped. By arranging the cooling mechanism 4 on both sides of the printing platform 3, it is avoided that the cooling mechanism 4 affects the movement of the print head inside the 3D printer 1, and the practicability is high.

[0022] In this embodiment, a groove is provided at the top of the storage bin 6, and the groove is arranged at the bottom of the printing platform 3. The semiconductor refrigeration sheet 7 is fixedly installed inside the groove. A cold conduction plate 15 is fixedly provided on the top of the semiconductor refrigeration sheet 7, and the cold conduction plate 15 is arranged inside the groove. A heat conduction plate 8 is fixedly provided at the bottom of the semiconductor refrigeration sheet 7, and the bottom end of the heat conduction plate 8 is fixedly arranged inside the storage bin 6. A front air inlet 5 and a rear air outlet 9 are equidistantly provided inside the front and rear ends of the storage bin 6, and a heat conduction plate 8 is fixedly provided inside the front air inlet 5. Ventilation fan, fixed tubes 17 are fixedly installed inside the storage bins 6 on both sides of the groove, and a telescopic tube 16 is fixedly installed on the top of the fixed tube 17. The cold generated by the semiconductor refrigeration chip 7 can be guided out through the cold conduction plate 15, which is convenient for the subsequent discharge of cold air. The heat of the semiconductor refrigeration chip 7 can be guided out through the heat conduction plate 8, and the heat is dissipated through the front air inlet 5, the ventilation fan and the rear air outlet 9 to ensure the normal operation of the semiconductor refrigeration chip 7. The cold air inside the groove can be discharged through the fixed tube 17 and the telescopic tube 16, which is convenient for the subsequent cooling of the print.

[0023] In this embodiment, a first circulation port 10 is opened on the inner wall of the rear side of the 3D printer 1 corresponding to the top of the printing platform 3, and a powerful fan is fixedly installed inside the first circulation port 10. A second circulation port 11 is opened on the inner wall of the rear side of the 3D printer 1 corresponding to the bottom of the printing platform 3, and a circulation pipe 18 is fixedly installed between the first circulation port 10 and the second circulation port 11.

When the powerful fan is in operation, the air inside the 3D printer 1 can be discharged from the inside of the groove through the first circulation port 10, the circulation pipe 18 and the second circulation port 11, thereby circulating the air to avoid energy waste.

[0024] In this embodiment, a box door 2 is installed inside the front end of the 3D printer 1 through a pivot, and the bottom end of the hydraulic rod 12 is fixedly arranged inside the storage bin 6. The fixing plate 13 can be raised and lowered by the hydraulic rod 12 to facilitate cooling of the printed part.

[0025] When the print air circulation cooling device is used, the top of the telescopic tube 16 is fixedly connected to the nozzle 14, the box door 2 is closed, and when printing, the semiconductor refrigeration chip 7 is energized to reduce the top temperature of the semiconductor refrigeration chip 7 and increase the bottom temperature.

At the same time, the front air inlet 5 and the ventilation fan inside the heat conduction plate 8 are started to blow toward the heat conduction plate 8 to facilitate the heat dissipation of the semiconductor refrigeration chip 7. The powerful fan inside the first circulation port 10 is started, and the powerful fan draws the air inside the 3D printer 1 into the interior of the circulation pipe 18, and enters the interior of the groove through the circulation pipe 18 and the second circulation port 11, so that the air inside the groove The air pressure increases and enters the interior of the nozzle 14 through the fixed tube 17 and the telescopic tube 16. The nozzle 14 blows cold air toward the printed workpiece. As printing proceeds, the fixed plate 13 is driven to rise by the hydraulic rod 12, and the fixed plate 13 drives the nozzle 14 and stretches the telescopic tube 16, thereby cooling the printed workpiece. The air inside the 3D printer 1 forms a cycle through the first circulation port 10, the circulation tube 18, the second circulation port 11, the groove, the fixed tube 17, the telescopic tube 16 and the nozzle 14, which is convenient for recycling cold air and avoids energy waste. The 3D printer 1 has high practicality. By arranging the fixed plate 13, the nozzle, etc. on both sides of the printing platform 3 and driving the cooling mechanism 4 to rise and fall by the hydraulic rod 12, collision between the printing head and the cooling mechanism 4 is avoided.
