[0027] Embodiment 1

[0028] The technical solution in the embodiment of the present application is to effectively solve the technical problems that the above-mentioned device uses organic solvent ethanol to absorb the harmful gases generated by the photosensitive resin. This absorption device needs to be carried by staff, which is extremely inconvenient. In addition, the feeding port of the stirring device cannot be sealed, and toxic gases are likely to overflow from here, resulting in low practicability. The general idea is as follows:

[0029] In view of the problems existing in the prior art, the utility model provides a light-curing 3D printing color material mixing device, which includes a stirring tank 1, a driving motor 104 is fixedly installed in the middle of the top of the stirring tank 1, the output end of the driving motor 104 is drivingly connected with a stirring roller 105, a raw material outlet 101 is fixedly installed on one side of the bottom of the stirring tank 1, an exhaust fan 3 is fixedly installed on one side of the top of the stirring tank 1, a filter screen 32 is fixedly connected inside the exhaust fan 3, one end of the exhaust fan 3 is fixedly connected with a flexible pipe 31, a feeding box 21 is fixedly installed on the other side of the top of the stirring tank 1, a sealing cover 22 is movably connected to the top of the feeding box 21, a sealing component 2 is arranged between the feeding box 21 and the sealing cover 22, an absorption box 4, which is movably connected to one end of the flexible pipe 31, fixing components 5 are fixedly arranged on both sides of the absorption box 4, a solvent inlet 41 is fixedly installed on the top of the absorption box 4, a guide plate 44 is fixedly connected to the bottom inside the absorption box 4, and a liquid outlet 45 is fixedly installed on one side of the bottom of the absorption box 4.

[0030] In some embodiments, the sealing component 2 includes a clamping block 201, which is fixedly connected to one side of the sealing cover 22, a clamping groove 203 is fixedly connected to one side of the feeding box 21, a clamping hole 202 is formed on the surface of the clamping block 201, a notch 207 is formed in the middle of the clamping groove 203, a clamping rod 204 is inserted into one side of the notch 207, a spring 206 is arranged around the surface of the clamping rod 204, and a stop piece 205 is fixedly installed at one end of the clamping rod 204 close to the notch 207, as Figures 1-5As shown, when the mixing tank 1 needs to be sealed, first pull the clamping rod 204 outwards. The clamping rod 204 compresses the spring 206 under the action of the retaining piece 205. At this time, insert the clamping block 201 into the notch 207 inside the clamping groove 203. Stop pulling the clamping rod 204, and it enters the inside of the clamping hole 202 under the action of the spring 206, thus completing the sealing of the blanking box 21 and preventing harmful gases from overflowing from here.

[0032] In the specific implementation process, when the mixing tank 1 needs to be sealed, first pull the clamping rod 204 outwards. The clamping rod 204 compresses the spring 206 under the action of the retaining piece 205. At this time, insert the clamping block 201 into the notch 207 inside the clamping groove 203. Stop pulling the clamping rod 204, and it enters the inside of the clamping hole 202 under the action of the spring 206, thus completing the sealing of the blanking box 21 and preventing harmful gases from overflowing from here. When the absorption tank 4 needs to be fixed, first rotate the runner 53. The runner 53 drives the screw rod 52 to rotate. At this time, the screw rod 52 drives the grounding plate 55 to move downwards. Since the screw rod 52 is connected to the grounding plate 55 through a bearing and the grounding plate 55 is restricted by the guide rod 54 and will not rotate, until the pressurizing plate 551 inside the grounding plate 55 contacts the ground. Continue to rotate the runner 53. At this time, the grounding plate 55 starts to squeeze the pressurizing spring 552. Under the action of the pressurizing spring 552, the pressurizing plate 551 contacts the ground more fully, improving the fastening effect.

A pressurizing spring 552 is fixedly connected to the top of the pressurizing plate 551. As Figures 1-5As shown, continue to rotate the rotating wheel 53. At this time, the grounding plate 55 opens and compresses the pressurizing spring 552. Under the action of the pressurizing spring 552, the pressurizing plate 551 contacts the ground more fully, improving the fastening effect.

[0036] Embodiment 3

[0037] Based on Embodiment 1, the embodiment of the present application is a feasible technical solution for a light-curing 3D printing color material mixing device. The general idea is as follows:

[0038] In some embodiments, an anti-slip pad 102 is fixedly connected to the bottom of the mixing tank 1.

[0039] Embodiment 4

[0040] Based on Embodiment 1, the embodiment of the present application is a feasible technical solution for a light-curing 3D printing color material mixing device. The general idea is as follows:

[0041] In some embodiments, anti-slip patterns are fixedly provided at the bottom of the pressurizing plate 551, as Figure 1 - shown, which can improve the fastening effect. The top of the screw 52 is fixedly connected to a rotating wheel 53. A plurality of universal wheels 43 are fixedly connected to the bottom of the absorption box 4, as Figures 1-5 shown, which can facilitate the movement of the absorption box 4.

[0042] The working principles of the mixing tank 1, the exhaust fan 3, and the absorption box 4 in the present utility model have been disclosed in a mixing device for 3D printing light-curing materials disclosed in Chinese Patent Application No. CN202123346408.9. Its working principle is that when in use, first start the air extraction pump 7. The suction end of the air extraction pump 7 sucks air through the suction pipe 6 and the suction plate 4, and then transmits it through the air outlet pipe 8 to the first connection column 9 and the second connection column 10, and finally enters the absorption box 11. And the filter plate 5 can filter the dust in the air when the air extraction pump 7 is working, preventing the dust from contaminating the liquid in the absorption box 11, improving the service life of ether or ethanol in the absorption box 11, and the filter plate 5 can be pulled out from the suction plate 4 through the pulling groove to clean and replace the filter plate 5. And a dust-proof plate 15 is connected through the support column 18, effectively preventing the dust from falling into the ventilation holes and entering the absorption box 11. When the liquid in the absorption box 11 needs to be replaced, the first connection column 9 and the second connection column 10 can be separated by rotating the threaded stud 16, so that the absorption box 11 can be separated from the air extraction pump 7. Shake the absorption box 11, and the spring layer 12 will better shake the absorption box 11, and the liquid guide plate 19 will better guide out the solution in the absorption box 11.

[0043] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly illustrating the present utility model, rather than limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation manners here. And the obvious changes or modifications derived therefrom are still within the protection scope of the present utility model.
