[0037] The following further elaborates on this application Figure 1 - Figure 7 in conjunction with the attached drawings.

[0038] The embodiment of this application discloses a cleaning device for 3D printing resin.

[0039] Referring to Figure 1 , Figure 2 , Figure 3 A cleaning device for 3D printing resin includes the body 1 of the printer and the resin box 2. On one side of the resin box 2, there are two movable seats 3 fixed on the inner side wall of the inner cavity of the body 1. The two movable seats 3 are symmetrically arranged, and their structures and installation methods are the same. The inner side walls of the two movable seats 3 are in contact with the two side surfaces of the telescopic slide rail 4, and they rotate relative to each other with a certain damping. One end of the second spring 14 is fixedly connected to the inner cavity surface of the telescopic slide rail 4 close to the movable seat 3, and the other end of the second spring 14 is fixedly connected to the surface of the extended end of the telescopic slide rail 4. On the surface of one side of the inner cavity of the telescopic slide rail 4, one side surface of the rack 5 is fixedly connected, and the rack 5 is meshed with the first gear 92.

[0040] Two movable seats 3 with the same structure and symmetrically arranged are fixedly connected to one side inner wall of the body 1, and the movable seat 3 and the telescopic slide rail 4 are rotatably arranged with a certain damping. Therefore, when the telescopic slide rail 4 rotates 90° in the movable seat 3 and fits with the inner wall of the body 1, it will play a certain limiting role. One side of the inner cavity of the telescopic slide rail 4 is fixedly provided with a rack 5, and the other side is a smooth surface, which can neither affect the meshing of the first gear 92 and the rack 5 nor affect the movement of the first gear 92 in the inner cavity of the telescopic slide rail 4.

[0041] Referring to Figure 5 , Figure 6 , Figure 7, a cleaning mechanism 9 is provided on one side of the rack 5. The cleaning mechanism 9 includes a first gear 92 meshed on one side of the rack 5. A rotating shaft 912 is fixedly penetrated through the middle of the first gear 92. The outer surface of the upper part of the rotating shaft 912 is rotatably connected to a limit disk 91. The height of the limit disk 91 is higher than that of the first gear 92. The lower surface of the upper part of the limit disk 91 is attached to the upper surface of the telescopic slide rail 4, and the upper surface of the lower part of the limit disk 91 is attached to the lower surface of the telescopic slide rail 4. Therefore, the limit disk 91 and the telescopic slide rail 4 are slidably arranged relative to each other. The lower end of the rotating shaft 912 is fixedly penetrated through the middle of the upper surface of the cleaning cover 93. The middle position of the inner cavity side wall of the cleaning cover 93 is fixedly connected to one side surface of four cross bars 99. The four cross bars 99 are arranged in an array, and their structures and installation methods are the same. The four cross bars 99 are fixedly penetrated by fixing rods 98 away from one side of the side wall of the cleaning cover 93. The cross bars 99 are fixed in the middle position of the fixing rods 98. The outer surface of the lower part of each fixing rod 98 is fixedly connected to one side surface of three triangular cleaning cutters 910. The three triangular cleaning cutters 910 fixed to the lower part of each fixing rod 98 are arranged in an array. A second gear 97 is fixedly penetrated through the upper part of each fixing rod 98. The four second gears 97 are all meshed with an internal gear ring 96. The outside of the internal gear ring 96 is fixedly connected to the inner surface of a fixed disk 95. The middle of the upper surface of the fixed disk 95 is fixedly penetrated by a negative pressure suction pipe 94. A heating filament 911 is fixedly arranged in a circle on the lower surface of the fixed disk 95. The heating filament 911 can heat and melt the hardened resin. A cleaning brush 10 is fixedly arranged in a circle on the outer surface of the cleaning cover 93, and the cleaning brush 10 has a good cleaning effect.

[0042] The first gear 92 is meshed with the rack 5, which enables the first gear 92 to rotate on its own when moving in the telescopic slide rail 4 and drives the rotating shaft 912 fixedly connected thereto to rotate. The lower surface of the upper part and the upper surface of the lower part of the limit disk 91 rotatably arranged on the outer surface of the upper part of the rotating shaft 912 can just be attached to and slide relative to the upper surface and the lower surface of the telescopic slide rail 4. Therefore, when the first gear 92 and the rotating shaft 912 rotate, the limit disk 91 will not rotate along with it, but the rotation of the rotating shaft 912 can drive the cleaning cover 93 fixedly connected to its lower part to rotate along with it, and further drive the cross bars 99 and the fixing rods 98 fixedly connected to the inner wall of the cleaning cover 93 to revolve. When the fixing rods 98 revolve, since the second gears 97 fixedly connected to the upper parts of the fixing rods 98 and the internal gear ring 96 are meshed, the second gears 97 and the fixing rods 98 can rotate on their own while revolving, and at the same time drive the triangular cleaning cutters 910 fixedly connected to the lower surface of the fixing rods 98 to rotate on their own, so that the triangular cleaning cutters 910 can break the hardened resin, so that the negative pressure suction pipe 94 sucks away the broken resin. One side of the upper part of the negative pressure suction pipe 94 is fixedly connected to one side of the limit disk 91 (as Figure 3As shown, the negative pressure suction pipe 94 will not rotate together with the rotating shaft 912, and the fixed disk 95 fixedly arranged in the middle of the negative pressure suction pipe 94 and the internal gear ring 96 will not rotate either. Only in this way can the second gear 97 rotate around the sun while rotating on its own axis.

[0043] It should be noted that the four cross bars 99, the second gear 97, the fixed rod 98, and the triangular cleaning tool 910 fixedly arranged at the lower part of the fixed rod 98 should be no less than three, and four is the best. And the number of the triangular cleaning tools 910 fixedly arranged at the lower part of the fixed rod 98 should be at least two, and three is the best. Otherwise, the cleaning effect will be affected.

[0044] Refer to Figure 2 、 Figure 3 、 Figure 4 The limiting disk 91 is arranged with a flat surface on one side of the rack 5, and both sides of this flat surface are fixedly connected to one side of two symmetrically arranged rollers 11. And one side surface of the roller 11 far from the movable seat 3 is fixedly connected to one end of the pull rope 7, and the end of the pull rope 7 far from the roller 11 is fixedly connected to the wire reel 13. And one side surface of the roller 11 on the side of the movable seat 3 is fixedly connected to one end of the first spring 8, and the side of the first spring 8 far from the roller 11 is fixedly connected to the inner wall of one side of the limiting strip 6. And one side surface of the wire reel 13 is fixedly connected to the output end of the micro servo motor 12. And the roller 11, the pull rope 7, and the first spring 8 are all located in the inner cavity of the limiting strip 6 and can slide in the inner cavity of the limiting strip 6. And the lower surface of the limiting strip 6 is fixedly connected to one side of the upper surface of the telescopic slide rail 4.

[0045] The rotation of the output end of the micro servo motor 12 can drive the wire reel 13 to rotate, winding or releasing the pull rope 7. When the pull rope 7 is wound, it can pull the roller 11 to move in the inner cavity of the limiting strip 6, and then pull the entire cleaning mechanism 9 to move. And when the roller 11 moves, the limiting strip 6 can play a role in supporting and guiding, and the first spring 8 will also be stretched following the movement of the roller 11. And the limiting strip 6 can also play a supporting role when the first spring 8 is stretched, especially at the semi-circular part of the telescopic slide rail 4. When the wire reel 13 releases the pull rope 7, the first spring 8 can also pull the roller 11 and the entire cleaning mechanism 9 back to achieve reciprocating motion.

[0046] It should be noted that usually, this device is closely attached to the inner wall of the printer body 1 through the cooperation of the telescopic slide rail 4 and the movable seat 3. And when leaning against the side wall of the printer body 1, the extended end of the telescopic slide rail 4 will retract into the telescopic slide rail 4 following gravity, which can save space and will not affect the normal printing of the printer.

[0047] The main body 1 of the printer, the resin cartridge 2, the micro servo motor 12, the heating filament 911, and the negative pressure suction pipe 94 are all prior arts, and their structural principles will not be elaborated too much. In addition, this device also requires a PLC to control the micro servo motor 12 and the suction device to cooperate with the negative pressure suction pipe 94. The PLC and the suction device are also prior arts and will not be elaborated too much here.

[0048] The implementation principle of the 3D printing resin cleaning device in the embodiment of the present application is as follows: When the staff is ready to clean the resin cartridge 2, they only need to rotate the telescopic slide rail 4 connected to the movable seat 3 of the device leaning against the inner cavity side wall of the main body 1, and then adjust the telescopic slide rail 4 to a state parallel to the resin cartridge 2, and the cleaning brush bristles 10 are in contact with the bottom surface of the resin cartridge 2. At this time, the extending end of the telescopic slide rail 4 is pushed out under the action of the second spring 14. At this time, the staff can turn on the control switch of the micro servo motor 12 to make the micro servo motor 12 work. The output end of the micro servo motor 12 rotates clockwise, and drives the wire reel 13 to wind up the pulling rope 7, thereby driving the pulling rope 7 to drive the roller 11 and the limit disk 91 fixedly connected to the roller 11 to move, thus driving the entire cleaning mechanism 9 to move. Since the first gear 92 and the rack 5 are meshed, when the first gear 92 moves, it will rotate itself. At this time, the first gear 92 will drive the cleaning cover 93 to rotate. The cleaning cover 93 can drive the cross bar 99, the fixed rod 98 and the second gear 97 to revolve. And because the second gear 97 and the internal gear ring 96 are meshed, and since the internal gear ring 96 is fixed and immovable, when the second gear 97 follows the revolution, it also rotates itself and can drive the triangular cleaning tool 910 to rotate itself to clean the hardened resin in the resin cartridge 2. The heating filament 911 arranged at the lower part of the fixed disk 95 can melt the hardened resin, which is convenient for the negative pressure suction pipe 94 to suck out the resin. The cleaning brush bristles 10 fixedly arranged outside the cleaning cover 93 can not only clean the resin on the bottom surface, but also clean the resin remaining on the side wall and the corner.

[0049] When the entire cleaning mechanism 9 moves to one side of the micro servo motor 12, the wire reel 13 stops winding and will release the pulling rope 7. At this time, the first spring 8 will pull the entire cleaning mechanism 9 back to realize reciprocating cleaning.

[0050] The above are all the preferred embodiments of the present application, and the protection scope of the present application is not limited hereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
