Description

Technical Field

[0001] The present application relates to the technical field of 3D printing, and in particular to a real-time drying device for 3D printing consumables. Background Art

[0002] Currently, consumables used in printing are sometimes stored improperly and become damp, requiring pre-drying to maintain their printing and material properties. Existing pre-drying methods typically involve placing the reel and consumables in a high-temperature, constant-temperature chamber for heating. This process, taking advantage of the fact that hot air absorbs moisture more readily, allows moisture in the consumables to escape into the air, effectively drying the damp consumables.

[0003] However, the above-mentioned solution for drying the consumables has the following disadvantages: the consumables need to be dried in advance for 4 to 12 hours (depending on the type of consumables), which makes the preparation time too long and is not conducive to rapid 3D printing production. Summary of the Invention

At this time, the air in the drying pipe becomes humid hot air; then the humid hot air in the drying pipe enters the cold end of the refrigerator through the cooling inlet pipe, so that the heat of the humid hot air can be discharged, thereby forming humid cold air; then the humid cold air passes through The refrigeration outlet pipe enters the desiccant box to form dry cold air; then, the dry cold air enters the cooling pipe through the dry outlet pipe, so that the consumables can be cooled; next, the dry cold air enters the air pump through the pump inlet pipe, which can cool the air pump, thereby completing a whole cycle; in summary, by adopting the above scheme, by using the device scheme for real-time drying of consumables proposed in this application, the consumables do not need to be dried for several hours in advance. Only the consumables need to be passed into the device when preparing for the printing task, and then sent into the 3D printer through the device to achieve real-time drying, saving the lengthy pre-drying time of the consumables required for the 3D printing process, thereby facilitating rapid production of 3D printing.

[0036] The following is combined with Figure 1-10 This application is described in further detail.

[0037] Identical components are denoted by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "upper," "lower," "bottom," and "top" used in the following description refer to directions in the accompanying drawings, and the terms "inner" and "outer" refer to directions toward or away from the geometric center of a particular component, respectively.

[0038] Example 1: A real-time drying device for 3D printing consumables, such as Figure 1-Figure 5 As shown, it includes a shell 2 and a power connection unit 21 installed on the shell 2; a preheating tube 22 and a cooling tube 24 are installed in the shell 2, and the end of the preheating tube 22 close to the cooling tube 24 is connected to the drying tube 23 through a pipeline, and the preheating tube 22 is also connected to the drying tube 23 through an external tube 25. The consumables 1 pass through the shell 2, the preheating tube 22, the drying tube 23 and the cooling tube 24 in sequence; an air pump 26, a refrigerator 27, a heater 28 and a desiccant box 29 are installed in the shell 2, and the cooling tube 24 is connected to the air pump 26 through the pump inlet pipe 261. The inlet of the pump 26 is connected, and the outlet of the air pump 26 is connected to the hot end 271 of the refrigerator 27 through the pump outlet pipe 262. The hot end 271 of the refrigerator 27 is connected to the heater 28 through the heating inlet pipe 281. The heater 28 is connected to the preheating pipe 22 through the heating outlet pipe 282. The drying pipe 23 is connected to the cold end 273 of the refrigerator 27 through the cooling inlet pipe 272. The cold end 273 of the refrigerator 27 is connected to the desiccant box 29 through the cooling outlet pipe 274. The desiccant box 29 is connected to the cooling pipe 24 through the drying outlet pipe 291.

[0039] like Figure 3 and Figure 5 As shown, a temperature sensor 283 is installed on the heating outlet pipe 282. The temperature sensor 283 is electrically connected to the heater 28 through a controller, which can be a PLC. The heating power of the heater 28 can be adjusted through the temperature sensor 283 and the controller.

[0040] like Figure 1 and Figure 2 As shown, a radiator 3 is mounted on the hot end 271 of the refrigerator 27. The radiator 3 includes a heat sink 31 connected to the hot end 271 of the refrigerator 27 and a plurality of cooling fans 32 mounted at both ends of the heat sink 31. The housing 2 is provided with a plurality of cooling vents 20, which are arranged in a one-to-one correspondence with the plurality of cooling fans 32. Furthermore, theoretical analysis shows that, for the refrigerator 27, the cold air received by the cold end 273 of the refrigerator 27 is insufficient to sufficiently cool the waste heat discharged from the hot end 271 of the refrigerator 27. Therefore, the radiator 3 is introduced to dissipate heat from the hot end 271 of the refrigerator 27.

[0041] Working principle: First, the air pump 26 extracts dry cold air from the cooling pipe 24 through the pump inlet pipe 261, and then sends it to the hot end 271 of the refrigerator 27 through the pump outlet pipe 262; then the dry cold air is initially heated by the hot end 271 of the refrigerator 27 to become hot dry air, and then the hot dry air enters the heater 28 through the heating inlet pipe 281 for secondary heating to the specified temperature; next, the hot dry air enters the preheating pipe 22 and the drying pipe 23 through the heating outlet pipe 282, and quickly raises the consumables 1 to the target temperature in the preheating pipe 22, and takes away the moisture of the consumables 1 in the drying pipe 23. At this time, the air in the drying pipe 23 becomes humid hot air; then the humid hot air in the drying pipe 23 enters the cold end 273 of the refrigerator 27 through the cooling inlet pipe 272, so that the heat of the humid hot air can be discharged. This forms wet cold air; the wet cold air then enters the desiccant box 29 through the refrigeration outlet pipe 274, thereby forming dry cold air; then, the dry cold air enters the cooling pipe 24 through the drying outlet pipe 291, thereby cooling the consumable 1; next, the dry cold air enters the air pump 26 through the pump inlet pipe 261, which can cool the air pump 26, thereby completing a whole cycle; in summary, by adopting the above scheme, by using the device scheme for real-time drying of consumables 1 proposed in this application, the consumables 1 do not need to be dried for several hours in advance. It is only necessary to pass the consumables 1 into the device when preparing for the printing task, and then send it into the 3D printer through the device to achieve real-time drying, saving the lengthy pre-drying time of the consumables 1 required for the 3D printing process, which is conducive to rapid production of 3D printing.

When heat dissipation is not required, the first electric push rod 42 is first activated. At this time, the output end of the first electric push rod 42 drives the sealing plate 43 to seal the heat dissipation port 20, thereby reducing the ingress of dust into the housing 2.
