DETAILED DESCRIPTION

[0040] The utility model will be explained further in detail now in combination with the drawings. These drawings are all simplified schematic diagrams, and only illustrate the basic structure of the utility model in a schematic manner, so they only show the relevant components of the utility model.

[0041] As Figures 1-7 The specific embodiment of the utility model with automatic feeding function of light-cured 3D printer shown in the figure includes rack 1, rotating platform 2 rotatingly installed on rack 1, at least one trough 3 arranged on rotating platform 2, automatic feeding device 4 installed on rack 1 and printing device 5 for 3D printing. We should understand that the rotating platform 2 mentioned in this embodiment can drive the trough 3 to rotate on the rack 1, and the specific structures of the rotating platform 2, the trough 3 and the rack 1 can all adopt the structures in the prior art, such as the patent number CN117162483 of the applicant's prior application, and the specific structure implementation of the rotating platform 2, the trough 3 and the rack 1 etc. will not be elaborated here.

[0042] As Figure 2As shown, the automatic feeding device 4 in the embodiment includes at least one liquid storage tank 41 mounted on the rack 1 for storing printing raw materials, a "7" shaped feeding rack 42 fixedly mounted on the rack 1, a first liquid guide clamping block 43 mounted at the end of the "7" shaped feeding rack 42, and a liquid guide pipe 44, wherein one end of the liquid guide pipe 44 is connected with the liquid storage tank 41 through a liquid guide pump, the other end is clamped on the first liquid guide clamping block 43, and the liquid outlet of the liquid guide pipe 44 is located above the rotating platform 2 and is correspondingly arranged with the trough 3. In the embodiment, three troughs 3 are arranged in a circle on the rotating platform 2, and three liquid storage tanks 41 are correspondingly arranged. The three troughs 3 and the three liquid storage tanks 41 are one-to-one corresponding. Different materials of printing raw materials are arranged in the three troughs 3, and the printing raw materials in the liquid storage tank 41 are consistent with the printing raw materials in the corresponding trough 3. It should be understood that the number of the troughs 3 can also be one, two, four, etc. The number of the troughs 3 and the liquid storage tanks 41 can be reduced or increased according to the needs of the printing finished product and the types of printing materials required by the customer. Here, the number of the troughs 3 and the liquid storage tanks 41 is not absolutely limited.

[0043] In use, when the rotating platform 2 drives the trough 3 needing to be replenished with raw materials to rotate below the liquid outlet of the liquid guide pipe 44, the corresponding liquid guide pump is started to transport the raw materials in the corresponding liquid storage tank 41 to the trough 3 through the liquid guide pipe 44. That is, the printing position corresponding to the printing device 5 is arranged on the rotating platform 2, and the feeding position corresponding to the liquid outlet of the liquid guide pipe 44 is arranged. During printing operation, the trough 3 is located at the printing position of the rotating platform 2. When it is necessary to replenish the trough 3 with raw materials, the rotating platform 2 rotates the trough 3 to the feeding position for feeding operation. The replenishment process does not require manual assistance, and realizes rapid and automatic action.

[0044] Referring to Figure 2 To ensure the stability of the liquid guide pipe 44 on the "7" shaped feeding rack 42, the automatic feeding device 4 further includes at least one second liquid guide clamping block 45 mounted on the horizontal edge and / or vertical edge of the "7" shaped feeding rack 42. In the embodiment, one second liquid guide clamping block 45 is arranged on the horizontal edge and the vertical edge of the "7" shaped feeding rack 42. In use, one end of the liquid guide pipe 44 is connected with the liquid storage tank 41, and the other end sequentially passes through the second liquid guide clamping block 45 on the vertical edge of the "7" shaped feeding rack 42, the second liquid guide clamping block 45 on the horizontal edge of the "7" shaped feeding rack 42, and the first liquid guide clamping block 43, so that the liquid outlet of the liquid guide pipe 44 is vertically downward or slightly inclined downward, thereby ensuring that the liquid outlet of the liquid guide pipe 44 corresponds to the trough 3 needing to be replenished with raw materials.

[0045] It should be further explained that, as Figure 5As shown, the second liquid guide clamp block 45 and the first liquid guide clamp block 43 are of the same structure, and here only the structure of the first liquid guide clamp block 43 is taken as an example to be described in detail. The first liquid guide clamp block 43 comprises a clamp block body 431 fixedly installed at one end of the "7" shaped feeding rack 42, at least one clamp hole 432 for inserting the liquid guide pipe 44 is arranged on the clamp block body 431, and a cutout 433 is arranged at the other end of the clamp block body 431, and the cutout 433 extends into the clamp hole 432. In use, the liquid guide pipe 44 is first inserted into the clamp hole 432, and then the clamp block body 431 with the cutout 433 is fastened by a screw, so that the liquid guide pipe 44 is conveniently installed and the position of the liquid guide pipe 44 is kept stable during use.

[0046] As a preferred embodiment, in order to avoid real-time monitoring of the remaining material in the trough 3 by personnel, a liquid level sensor for real-time monitoring of the material level in the corresponding trough 3 is arranged on the inner side of the trough 3. When the liquid level in the trough 3 is lower than a set threshold, the feeding is started, so that the automatic detection of the required material of the printer, the judgment of the remaining material and the feeding are completely automated, and the labor cost is reduced. It should be understood that the electrical elements such as the liquid guide pump and the liquid level sensor in the embodiment need to be provided with power to supply electric energy. The size, installation position and connection mode of the power supply with the electrical elements can be selected and adjusted by the person skilled in the art according to the actual use requirements, and here the size, installation position and connection mode of the power supply with the electrical elements are not described in detail.

[0047] As Figure 6As shown, the printing device 5 in the embodiment includes a lifting frame 51 fixedly installed on the frame 1, a lifting mechanism 52 installed on the lifting frame 51, and a printing platform 54 installed on the output end of the lifting mechanism 52 through a quick-change mechanism 53. The quick-change mechanism 53 includes a support plate 521 connected with the output end of the lifting mechanism 52, a matching frame 522 fixedly arranged on the printing platform 54, a fastening slot 523 arranged on the side of the matching frame 522 matched with the support plate 521, a fastening screw hole 524 arranged on the support plate 521, and a fastening screw 525 matched with the fastening slot 523 and the fastening screw hole 524. When the printing platform 54 needs to be fastened and matched with the support plate 521, the fastening screw 525 is screwed into the fastening screw hole 524 through the fastening slot 523. When a printing platform 54 of a different model or size needs to be replaced, the fastening screw 525 needs to be manually screwed, the original printing platform 54 is removed from the support plate 521 by using the fastening slot 523 on the corresponding matching frame 522 of the printing platform 54, the corresponding matching frame 522 of the printing platform 54 to be replaced is installed on the support plate 521, and the fastening screw 525 is screwed to achieve the replacement of the printing platform 54. The quick-change mechanism 53 in the embodiment can quickly replace the printing platform 54 through the loosening and tightening of the fastening screw 525, and the operation is simple and the replacement speed is fast.

[0048] In actual application, it is found that the smoothness of the printing surface of the printing platform 54 has a great influence on the ease of taking the finished product of different materials, specifically, for a standard smooth surface, the relative universality is strong for the use of conventional rigid materials, the adhesion and demolding difficulty are moderate, for an anodized surface, the relative adhesion is weak for the flexible material with strong adhesion, the demolding is easy, and for an 80-mesh frosted surface, the relative adhesion is strong for the powder material with weak adhesion. Therefore, the printing surface of the printing platform 54 in the embodiment adopts one of a smooth surface, an anodized surface, and an 80-mesh frosted surface, and the specific adjustment is made according to the different use materials.

[0049] In actual use, in order to avoid that the material after printing is not solidified and residual liquid drops fall on the rotating platform 2 or other material hoppers 3, such as Figure 7As shown, the cleaning mechanism 57 in the embodiment is provided with a drip-proof mechanism 55 on the lifting mechanism 52, the cleaning mechanism 57 drip-proof mechanism 55 comprising a drip-proof motor 551 fixedly installed on the lifting frame 51 of the cleaning mechanism 57, and a drip-proof baffle 552 coaxially arranged with the output shaft of the cleaning mechanism 57 drip-proof motor 551. The cleaning mechanism 57 drip-proof motor 551 drives the cleaning mechanism 57 drip-proof baffle 552 to rotate with the vertical direction as the rotation axis. After the printing is completed, the drip-proof motor 551 is started to rotate, driving the drip-proof baffle 552 to rotate to the lower side of the printed object adhered on the printing platform 54, which can effectively prevent the residual droplets on the printed object from falling.

[0050] As Figures 1-3 As shown, the rotating platform 2 of the light-curing 3D printer of the embodiment is further provided with a blow-drying mechanism 56 for performing a blow-drying process on the printed object and a cleaning mechanism 57 for cleaning the printed object. In the 3D technology, the blow-drying and cleaning of the printed object are relatively common processes, and the blow-drying mechanism 56 and the cleaning mechanism 57 that can be easily obtained on the market can be directly or modifiedly applied to the embodiment, and the specific structure of the blow-drying mechanism 56 and the cleaning mechanism 57 will not be described in detail here.

[0051] It should be understood that the specific embodiments described above are only used to explain the present application, and are not used to limit the present application. The obvious changes or modifications derived from the spirit of the present application are still within the protection scope of the present application.
