[0026] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention and are not used to limit the present invention.

[0027] Example: Figure 1-4 As shown, the utility model provides a technical solution, a resin filtering mechanism for 3D printing equipment, comprising a fixed support box 1, a dual filter assembly 2 is provided at the side end of the fixed support box 1, and the dual filter assembly 2 includes a centrifugal fixed barrel 201, a transmission motor 202, a centrifugal frame 203, a closing support frame 204, a lifting electric push rod 205, a snap-fit ​​sealing cover 206, an alignment snap-fit ​​strip 207, an intercepting net box 208, a reflux matching pipe 209, a reflux pump 210, a separation pipe rack 211 and a separation pump 212;

[0028] The bottom end of the fixed support box 1 is connected with a centrifugal fixed barrel 201, and a transmission motor 202 is installed at the bottom end of the centrifugal fixed barrel 201 through a motor seat. The output shaft of the transmission motor 202 is fixedly connected to a centrifugal frame 203 at a position corresponding to the centrifugal fixed barrel 201. The centrifugal frame 203 is rotatably installed on the inner side of the centrifugal fixed barrel 201 to achieve steady centrifugal processing. The top of the fixed support box 1 is clamped with a closing support frame 204, and the top of the closing support frame 204 is clamped with a lifting electric push rod 205. The bottom end of the lifting electric push rod 205 is clamped with a clamping sealing cover 206. The top of the inner side of the fixed support box 1 is fixed with an alignment clamping strip 207, and the top of the alignment clamping strip 207 is clamped with an interception net box 208.

[0029] A reflux matching pipe 209 is connected through one end of the fixed support box 1 at the position corresponding to the snap-fit ​​sealing cover 206, and a reflux pump 210 is installed through the motor base at one end of the fixed support box 1 at the position corresponding to the reflux matching pipe 209. A separation pipe rack 211 is connected through one end of the centrifugal fixed barrel 201 and the fixed support box 1. One end of the reflux matching pipe 209 is connected to one end of the reflux pump 210 through an adapter, and one end of the separation pump 212 is connected to one end of the separation pipe rack 211 through an adapter to achieve steady reflux processing. A separation pump 212 is installed through the motor base at one end of the fixed support box 1 at the position corresponding to the separation pipe rack 211;

[0030] For stable operation of the equipment, the input ends of the transmission motor 202 , the lifting electric push rod 205 , the reflux pump 210 and the separation pump 212 are all electrically connected to the output end of the external power supply.

[0031] A linkage assembly 3 is provided at the bottom end of the fixed support box 1, and the linkage assembly 3 includes a fixed electric push rod 301, a load-bearing assembly frame 302, a separation and collection box 303, a matching net box 304, a recovery pipe rack 305, a processing pump 306, an inlet pipe 307, an outlet pipe 308 and a limiting valve 309;

[0032] The bottom end of the fixed support box 1 is equidistantly connected to a number of fixed electric push rods 301, and the side ends of the fixed electric push rods 301 are connected to the load-bearing combination frame 302. The bottom end of the fixed support box 1 is fitted with the top of the load-bearing combination frame 302 to achieve steady alignment support and improve the stability of the support positioning. The bottom end of the inner side of the load-bearing combination frame 302 is connected to the separation and collection box 303, and the inner side of the separation and collection box 303 is sleeved with a matching net box 304. A recovery pipe rack 305 is connected between the separation and collection box 303 and the centrifugal fixed barrel 201. The recovery pipe rack 305 One end of 05 is connected to one end of the treatment pump 306 through an adapter to achieve steady reflux extraction. One end of the separation and collection box 303 is installed with a treatment pump 306 at the position of the recovery pipe rack 305 through a motor base. The top of the closed support frame 204 is penetrated by an inlet pipe 307. The bottom of the centrifugal fixed barrel 201 is equidistantly penetrated by several external discharge pipes 308. The external discharge pipes 308 are placed inside the matching net box 304 to ensure stable processing of external interception. One end of the inlet pipe 307 and the external discharge pipe 308 are embedded with a limiting valve 309.

[0033] For stable operation of the device, the input ends of the fixed electric push rod 301 , the process pump 306 and the limiting valve 309 are all electrically connected to the output end of the external power supply.

[0034] The working principle and use process of the present invention are as follows: when the resin is filtered, the lifting electric push rod 205 drives the locking sealing cover 206 to drive the centrifugal fixed barrel 201 to rise and open the centrifugal fixed barrel 201. At this time, the resin in the fixed support box 1 flows into the inner side of the centrifugal fixed barrel 201, and the transmission motor 202 drives the centrifugal frame 203 to centrifuge the resin in the centrifugal fixed barrel 201. During centrifugation, the lifting electric push rod 205 drives the locking sealing cover 206 to close and seal the centrifugal fixed barrel 201. At this time, the limiting valve 309 opens the inlet pipe 307 to inject new resin into the inner side of the fixed support box 1, thereby realizing continuous printing and resin filtering processing at the same time. The resin after centrifugation is extracted by the separation pump 212 and the separation tube rack 211 and flows back into the inner side of the fixed support box 1. The resin in the fixed support box 1 is extracted by the reflux pump 210 and the reflux matching pipe 209. The resin is intercepted and filtered by the interception net box 208, which is beneficial to multi-stage separation and improves the filtering effect.

[0035] After the centrifugal separation is completed, the limiting valve 309 opens the external discharge pipe 308 to discharge the remaining resin mixture into the inner side of the matching net box 304 at the position of the separation and collection box 303. The matching net box 304 is used to filter and separate the resin liquid, and the resin liquid flows into the inner side of the separation and collection box 303. The impurities are blocked and intercepted inside the matching net box 304. The processing pump 306 and the recovery pipe rack 305 extract the resin liquid inside the separation and collection box 303 and inject the resin liquid into the inner side of the centrifugal fixed barrel 201 to achieve further separation and recovery, ensuring sufficient treatment of the resin liquid and reducing resource waste. The fixed electric push rod 301 drives the fixed support box 1 to move upward to separate the fixed support box 1 and the load-bearing combination frame 302. At this time, the staff can take out and replace the matching net box 304 from the inner side of the separation and collection box 303, and the centrifugal separation of the resin liquid can continue at this time, thereby not affecting the overall operation and improving the processing efficiency.

[0036] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents.
