Therefore, a 3D printer waste powder recycling device is needed to meet people's needs.

[0006] Therefore, the purpose of this invention is to provide a waste powder recycling device for 3D printers.

[0007] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a waste powder recycling device for 3D printers, including a base, a support frame installed at the top of the base, and an installation box installed at the top of the support frame.

[0008] As a preferred embodiment of the waste powder recycling device for 3D printers of this utility model, the bottom end of the mounting box is equipped with a feeding pipe, and the inside of the feeding pipe is equipped with a solenoid valve body.

[0009] As a preferred embodiment of the waste powder recycling device for 3D printers of this utility model, the reciprocating sliding mechanism includes a mounting frame, which is fixedly installed on the side wall of the mounting box. A first rectangular hole is provided inside the mounting frame, and a second rectangular hole and a third rectangular hole are provided at the top and bottom of the mounting frame, respectively, and the second rectangular hole and the third rectangular hole are connected to the first rectangular hole.

[0010] As a preferred embodiment of the waste powder recycling device for 3D printers of this utility model, wherein: the interior of the first rectangular hole is provided with a mounting block body, and the top of the mounting block body is provided with a push plate that penetrates the second rectangular hole, and a connecting plate is provided at one end of the push plate that is close to each other.

[0011] As a preferred embodiment of the waste powder recycling device for 3D printers of this utility model, the bottom end of the mounting block body is equipped with a guide block body that cooperates with the third rectangular hole, and high-pressure spring bodies are installed on the side walls at both ends of the guide block body. The two ends of the high-pressure spring bodies are fixedly connected to the guide block body and the side wall of the third rectangular hole, respectively.

[0012] As a preferred embodiment of the waste powder recycling device for 3D printers of this utility model, the rotary extrusion mechanism includes a support plate, which is fixedly installed on the side wall of the mounting box.

[0015] The waste toner recycling device for 3D printers of this utility model has the following beneficial effects:

[0016] This invention first uses a stepper motor to drive the extrusion rod to rotate and extrude the mounting block body. The guide block body cooperates with the third rectangular hole, causing the extrusion rod to rotate and extrude the mounting block body. This compression causes the push plate and guide block body to slide, deforming the high-pressure spring body. The elastic recovery of the high-pressure spring body then causes the mounting block body and push plate to slide back and forth. This back and forth movement of the mounting block body and push plate, in turn, causes the filter box and wire mesh to slide back and forth, thus filtering the waste powder through the wire mesh.

[0017] This utility model firstly uses an arc-shaped base and a storage bucket to cooperate with each other, and connects to the main body of the bolt rod through a threaded hole. The main body of the through hole and the main body of the crossbar cooperate with each other, so that the main body of the bolt rod rotates and slides inside the threaded hole, and drives the extrusion plate to slide at the same time. This makes it easy for the extrusion plate to slide to position and fix the storage bucket and the arc-shaped base, thus making it easy for operators to install and disassemble the storage bucket.

[0029] Example 1: Refer to Figures 1-5This is the first embodiment of the present invention. This embodiment provides a waste powder recycling device for 3D printers, which enables the reuse of 3D printer waste powder. It is necessary to filter the impurities mixed in with the 3D printer waste powder to avoid the waste powder containing impurities during reuse, which would affect the use effect. At the same time, the filtered 3D printer waste powder is not convenient for operators to collect and clean, which causes inconvenience to operators. The device includes a base 1, a support frame 2 installed on the top of the base 1, and a mounting box 3 installed on the top of the support frame 2. A reciprocating sliding mechanism 4 is installed on one side wall inside the mounting box 3, and a filter component 5 is provided on the side wall of the reciprocating sliding mechanism 4. A feed pipe 301 is installed at the bottom of the mounting box 3, and a solenoid valve body 302 is installed inside the feed pipe 301.

[0030] Combination Figure 1 , Figure 2 and Figure 3 In an embodiment of this utility model, the reciprocating sliding mechanism 4 includes a mounting frame 401, which is fixedly mounted on the side wall of the mounting box 3. A first rectangular hole 402 is provided inside the mounting frame 401.

[0032] The specific working principle is as follows: When waste powder needs to be filtered for the 3D printer, the stepper motor 802 is first started to drive the drive shaft 803 and the extrusion rod 804 to rotate. The extrusion rod 804 rotates and extrudes the mounting block body 405. The guide block body 408 cooperates with the third rectangular hole 404 to make the extrusion rod 804 rotate and extrude the mounting block body 405. The extrusion of the mounting block body 405 can drive the push plate 406 and the guide block body 408 to slide and extrude the high-pressure spring body 409 to deform. The elastic recovery of the high-pressure spring body 409 drives the mounting block body 405 and the push plate 406 to slide back and forth. The back and forth sliding of the mounting block body 405 and the push plate 406 drives the filter box 501 and the wire mesh 502 to slide back and forth, thereby filtering the waste powder through the wire mesh 502.

[0033] Example 2: Refer to Figures 1-5 This is the first embodiment of the present invention. This embodiment provides a waste powder recycling device for 3D printers, which enables the reuse of 3D printer waste powder. It is necessary to filter the impurities mixed in with the 3D printer waste powder to avoid the waste powder containing impurities during reuse, which would affect the use effect. At the same time, the filtered 3D printer waste powder is not convenient for operators to collect and clean, which causes inconvenience to operators.

[0035] Combination Figure 2 , Figure 4 and Figure 5In an embodiment of this utility model, the installation and disassembly mechanism 7 includes a bolt rod body 701, which is threadedly connected to the inside of the threaded hole 603. One end of the bolt rod body 701 is rotatably mounted with a pressing plate 702 via a bearing, and an anti-slip pad is installed on the outer wall of the pressing plate 702. A crossbar body 703 that penetrates the through hole body 604 is installed on the side wall of the pressing plate 702.

[0036] The specific working principle is as follows: when it is necessary to collect the filtered waste toner from the 3D printer, the arc-shaped base 601 and the collection bucket 602 cooperate with each other and are threadedly connected to the bolt rod body 701 through the threaded hole 603. The through hole body 604 and the crossbar body 703 cooperate with each other, so that the bolt rod body 701 rotates and slides inside the threaded hole 603, driving the extrusion plate 702 to slide at the same time. This makes it easy for the extrusion plate 702 to slide and position and fix the collection bucket 602 and the arc-shaped base 601, thus making it easy for the operator to install and disassemble the collection bucket 602.
