[0020] In order to describe the technical content, structural features, achieved purposes and effects of the application in detail, the technical solutions in the embodiments of the application will be described below in conjunction with the drawings in the embodiments of the application. Obviously, the described embodiments are only a part of the embodiments of the application, rather than all of the embodiments. In the following description, for the purpose of explanation, many specific details are set forth to provide a detailed description of various exemplary embodiments or implementations of the invention. However, various exemplary embodiments may also be implemented without these specific details or in the case of one or more equivalent arrangements. In addition, various exemplary embodiments may be different, but are not necessarily exclusive. For example, without departing from the inventive concept, the specific shape, structure and characteristics of the exemplary embodiment may be used or implemented in another exemplary embodiment.

[0021] The present application embodiment provides an automatic feeding device for a 3D printer, such as Figure 1-3 As shown, the automatic feeding device 100 includes: a feeding trough 10 and a feeding mechanism 20 installed on the side wall of the feeding trough 10.

[0022] The trough 10 is located below the 3D printer's printing platform and holds consumables. The bottom of the trough 10 is made of a transparent material. A light source shines upward through the bottom of the trough 10, causing the consumables in the trough 10 to solidify into a 3D product on the printing platform based on the image projected by the light source.

[0023] The feeding mechanism 20 is detachably mounted on the side wall of the trough 10 , and automatically adds consumables into the trough 10 when the consumables in the trough 10 are reduced.

[0024] like Figure 1 、 5 As shown in Figures 6 and 7, the feeding mechanism 20 includes a storage bottle 1 and a feeding member 2. The storage bottle 1 is used to store consumables. The feeding member 2 has a feeding channel 21 for conveying the consumables in the storage bottle 1 to the material trough 10. The feeding channel 21 has a feeding port 211 that cooperates with the storage bottle 1 and a discharging port 212 that extends into the material trough 10. The feeding port 211 is located above the discharging port 212. The consumables in the storage bottle 1 are conveyed from the discharging port 212 to the material trough 10 via the feeding port 211. The feeding member 2 is further provided with a clamping groove 22 that is clamped with the side wall of the material trough 10. The clamping groove 22 is arranged to avoid the feeding channel 21. The feeding member 2 is detachably mounted on the material trough 10 through the clamping groove 22 and the side wall of the material trough 10, which facilitates the disassembly and assembly of the feeding member 2.

[0025] The feeding component 2 includes a first part 23 connected to the storage bottle 1, a second part 24 extending into the material trough 10 and a third part 25 located outside the material trough 10. The first part 23 is located on the upper side of the clamping groove 22, and the clamping groove 22 is formed between the second part 24 and the third part 25. The feed port 211 is opened on the first part 23, the discharge port 212 is opened on the second part 24, and the feeding channel 21 is formed inside the first part 23 and the second part 24; a through hole is opened on the third part 25, so that the third part 25 can be grasped, which facilitates the disassembly and assembly of the feeding mechanism 20.

[0026] like Figure 4 As shown, when the feeding member 2 is clamped on the side wall of the trough 10, there is a distance d between the discharge port 212 and the bottom of the trough 10 for the consumables to be discharged from the discharge port 212. In the embodiment of the present application, the distance d is 10mm-20mm.

[0027] The consumables in the material tank 10 are consumed during the printing process, and the liquid level of the consumables in the material tank 10 drops. Due to the pressure difference and the liquid level difference, the consumables in the storage bottle 1 are automatically replenished into the material tank 10 through the feeding channel 21, so that the liquid level of the consumables in the material tank 10 rises, realizing the automatic feeding function of the automatic feeding device 100.

[0028] The present application realizes the automatic feeding function of the automatic feeding device through the liquid level difference and pressure difference between the consumables in the storage bottle and the consumables in the material trough. It has a simple structure, convenient operation and low production cost.

[0029] The above shows and describes the basic principles, main features and advantages of the present application. Those skilled in the art should understand that the present application is not limited to the above embodiments. The above embodiments and descriptions are only for illustrative purposes. Various changes and improvements may be made to the present application without departing from the spirit and scope of the present application. The scope of protection claimed in the present application is defined by the appended claims, the description and their equivalents.
