[0002] A three-dimensional printer is a rapid prototyping process that uses a layer-by-layer stacking method to fabricate a three-dimensional model. Its operation process is similar to that of a traditional printer. However, a traditional printer prints ink on paper to form a two-dimensional flat drawing, while a three-dimensional printer stacks materials such as clay layer by layer through methods such as spraying adhesives or extrusion to form a three-dimensional entity. It can automatically and quickly transform design ideas into prototypes with certain structures and functions or directly manufacture parts, so as to quickly evaluate and modify product designs to respond to market demands and improve the competitiveness of enterprises.

Detailed implementation manners

[0029] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present utility model clearer and more understandable, the present utility model will be further described in detail below with reference to the Figures 1-11 accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0030] Referring to Figure 1 and Figure 2 , a clay 3D printer with a monitoring assembly, comprising a frame 1, a material barrel 2, a feeding device 3, a monitoring assembly 4, an extrusion machine 5, a connecting pipe 6 and a control device 7. The material barrel 2 is fixedly arranged on one side of the frame 1. The feeding device 3 includes a power assembly 31, a lifting rod 32 and a feeding tray 33. The power assembly 31 is fixedly arranged on one side of the bottom end of the material barrel 2. The lifting rod 32 is vertically arranged and penetrates through the material barrel 2. The feeding tray 33 is fixedly arranged at the top end of the lifting rod 32. The two ends of the connecting pipe 6 are respectively communicated with the material barrel 2 and the extrusion machine 5. The clay is loaded in the material barrel 2, and the power assembly 31 is used to drive the lifting rod 32 and the feeding tray 33 to rise, so as to extrude the clay in the material barrel 2 and feed it into the extrusion machine 5.

[0031] Referring to Figure 3 and Figure 4, the power component 31 is set as a drive motor, and a driving gear 311 is fixedly arranged on the rotating shaft of the drive motor. Correspondingly, a rotating shaft 11 is rotatably connected to the frame 1. The rotating shaft 11 is kept parallel to the rotating shaft of the drive motor. A driven gear 111 is fixedly arranged on the rotating shaft 11. The driving gear 311 and the driven gear 111 are connected by a transmission chain 312. A reversing gearbox 34 is arranged between the rotating shaft 11 and the lifting rod 32. The reversing gearbox 34 includes a worm 341 and a worm wheel 342. The worm 341 is fixedly arranged on the rotating shaft 11. A thread 321 is arranged on the surface of the lifting rod 32. The worm wheel 342 is threaded with the lifting rod 32 and meshes with the worm 341. The rotating shaft of the drive motor rotates to drive the driven gear 111 to rotate through the driving gear 311 and the transmission chain 312. The driven gear 111 rotates to drive the lifting rod 32 to lift through the meshing worm 341 and worm wheel 342, so as to extrude the clay in the material bucket 2 into the extruder 5.

[0032] Refer to Figure 3 , Figure 5 and Figure 6 , the monitoring component 4 is located at the bottom end of the material bucket 2. The monitoring component 4 includes a first sensor 41, a second sensor 42 and a third sensor 43 from top to bottom in sequence. The first sensor 41, the second sensor 42 and the third sensor 43 are all inductive sensors. The first sensor 41, the second sensor 42 and the third sensor 43 are all fixed to the frame 1 and located on one side of the lifting rod 32. The control device 7 includes a main control board 71 and a driver 72. The driver 72 is electrically connected to the main control board 71, and the first sensor 41 and the drive motor are both electrically connected to the driver 72. A first alarm 44 and a second alarm 45 are fixedly arranged on the frame 1. The first alarm 44 is set as a red light strip, and the second alarm 45 is set as a blue light strip. Thus, the second sensor 42 is electrically connected to the red light strip, and the third sensor 43 is electrically connected to the blue light strip.

[0033] Add clay to the material bucket 2. When the third sensor 43 senses that the bottom end of the lifting rod 32 is nearby, the third sensor 43 will transmit a signal to the blue light strip, causing the blue light strip to light up to prompt the staff that the amount of clay in the material bucket 2 is full. The lifting rod 32 and the feeding tray 33 rise to extrude the clay into the extruder 5. When the lifting rod 32 rises near the second sensor 42, the second sensor 42 will transmit a signal to the red light strip, causing the red light strip to light up to remind the staff that the clay in the material bucket 2 is about to be completely extruded. As the lifting rod 32 and the feeding tray 33 continue to rise to completely extrude the clay in the material bucket 2, at this time, the bottom end of the lifting rod 32 is near the first sensor 41, and the first sensor 41 transmits a signal to the driver 72, so that the driver 72 controls the drive motor to stop working. The setting of the red light strip and the blue light strip facilitates the staff to understand the amount of clay in the material bucket 2, so that sludge can be added to the material bucket 2.

[0034] Refer to Figure 7 , a moving frame 8 is horizontally and longitudinally slidably arranged on the frame 1, and the extruder 5 is horizontally and transversely slidably arranged on the moving frame 8. In order to enable the moving frame 8 to meet the moving requirements of horizontal longitudinal sliding, a longitudinal movement motor 12 is fixedly arranged on the frame 1, and a longitudinal movement rotating rod 121 is horizontally and transversely rotatably connected to the frame 1, and the longitudinal movement rotating rod 121 is driven to rotate by the longitudinal movement motor 12. At both ends of the longitudinal movement rotating rod 121, a first conveyor belt 122 is wound and driven. The two ends of the moving frame 8 are respectively fixed to the two conveyor belts. When the longitudinal movement rotating rod 121 rotates, the moving frame 8 and the extruder 5 are driven to make horizontal longitudinal sliding movements through the first conveyor belt 122.

[0035] In order to enable the extruder 5 to meet the moving requirements of horizontal transverse sliding on the moving frame 8, a transverse movement track 82 is horizontally and transversely fixedly arranged on the moving frame 8. Correspondingly, a transverse movement seat 83 is fixedly arranged on one side of the extruder 5, and the transverse movement seat 83 is seated on the transverse movement track 82. A transverse movement motor 81 is fixedly arranged on the moving frame 8, and a second conveyor belt 84 is driven on the rotating shaft of the transverse movement motor 81. The transverse movement seat 83 is fixed to the second conveyor belt 84. The rotating shaft of the transverse movement motor 81 rotates, thereby driving the conveyor belt to drive. During the transmission of the conveyor belt, the transverse movement seat 83 and the extruder 5 make horizontal transverse sliding movements, so as to realize the position adjustment of the extruder 5.

[0036] Refer to Figure 8 and Figure 9, the extruder 5 includes an extrusion motor 51, a hopper 52, a screw 53 and a discharge head 54. One side of the hopper 52 is fixed to the transverse movement seat 83, and both ends of the connecting pipe 6 are respectively communicated with the material barrel 2 and the hopper 52. The extrusion motor 51 is fixedly arranged on the hopper 52, so that the rotating shaft of the extrusion motor 51 passes through the hopper 52. One end of the screw 53 is fixed to the rotating shaft of the extrusion motor 51 and keeps a vertical state. The discharge head 54 is arranged at the bottom end of the hopper 52 and communicated with the screw 53. After the ceramic clay enters the hopper 52 through the connecting pipe 6, the rotating shaft of the extrusion motor 51 rotates to convey the ceramic clay to the discharge head 54 through the screw 53 and discharges it through the discharge head 54, thus completing 3D printing.

[0037] Refer to Figure 10 , a printing platform 9 is arranged on the frame 1 in a lifting and sliding manner. For this purpose, a lifting motor 91 is vertically and fixedly arranged on the frame 1. A lifting screw rod 92 is fixedly arranged on the rotating shaft of the lifting motor 91, and a nut seat 93 is threaded on the lifting screw rod 92. The bottom end of the nut seat 93 is fixedly provided with a fixing plate 94. A guide rod 95 is vertically arranged on the frame 1, so that the fixing plate 94 can move up and down along the guide rod 95. Finally, one side of the printing platform 9 is fixedly arranged on the fixing plate 94. The ceramic clay extruded by the extruder 5 is on the printing platform 9. When it is necessary to adjust the longitudinal distance between the printing platform 9 and the extruder 5, the rotating shaft of the lifting motor 91 rotates to drive the lifting screw rod 92 to rotate, thereby driving the nut seat 93, the fixing plate 94 and the printing platform 9 to move up and down.

[0038] Refer to Figure 11 , in addition, the driving motor, the longitudinal movement motor 12, the transverse movement motor 81, the extrusion motor 51 and the lifting motor 91 are all electrically connected to the driver 72. The main control board 71 controls the driver 72, so as to control the working states of the driving motor, the longitudinal movement motor 12, the transverse movement motor 81, the extrusion motor 51 and the lifting motor 91 through the driver 72. After using the ceramic clay 3D printer to complete 3D printing, in order to facilitate the stop of the ceramic clay 3D printer, an extruder bypass switch 13 is arranged on the surface of the frame 1 of the ceramic clay 3D printer, and the extruder bypass switch 13 is electrically connected to the driver 72. After the driving motor, the longitudinal movement motor 12, the transverse movement motor 81, the extrusion motor 51 and the lifting motor 91 are forced to stop, the driver 72 can still be controlled to start through the extruder bypass switch 13, so that the driving motor, the longitudinal movement motor 12, the transverse movement motor 81, the extrusion motor 51 and the lifting motor 91 continue to work.

[0039] The specific implementation principle of the embodiment of the present application is as follows: when the clay 3D printer is needed, clay is loaded into the material barrel 2 of the clay 3D printer. When the bottom end of the lifting rod 32 is located near the third sensor 43, the third sensor 43 transmits a signal to the blue light strip so that the blue light strip lights up, indicating that the material barrel 2 is full of clay. During the rotation process, the rotating shaft of the driving motor drives the rotating shaft 11 to rotate through the driving gear 311, the transmission chain 312 and the driven gear 111. The rotating shaft 11 drives the lifting rod 32 and the loading tray 33 to rise through the reversing gear box 34, so as to squeeze the clay into the connecting pipe 6 and transmit it to the silo 52.

[0040] The rotating shaft of the extruder motor 51 rotates to drive the screw 53 to rotate, and the screw 53 rotates to spirally convey the clay to the discharge head 54 and discharge it onto the printing platform 9, so as to perform 3D printing. The rotating shaft of the lifting motor 91 rotates to drive the lifting screw 92 to rotate, thereby driving the nut seat 93, the fixing plate 94 and the printing platform 9 to rise and fall, so as to adjust the distance between the printed product on the printing platform 9 and the extruder. The rotating shaft of the longitudinal motor 12 rotates to drive the longitudinal rotation rod 121 to rotate, and the longitudinal rotation rod 121 rotates to drive the first conveyor belt 122 arranged around its two ends to transmit, thereby driving the mobile frame 8 and the extruder 5 on the mobile frame 8 to move horizontally and longitudinally. The rotating shaft of the transverse motor 81 rotates to drive the second conveyor belt 84 arranged around its rotating shaft to transmit, and the second conveyor belt 84 drives the transverse seat 83 fixed to the extruder 5 to slide horizontally along the transverse track 82 during the transmission process, so as to adjust the horizontal and transverse position of the extruder 5. By adjusting the lifting and lowering of the printing platform 9, the horizontal longitudinal and horizontal lateral positions of the extruder 5 are adjusted, so that the clay 3D printer can perform complete 3D printing movement.

[0041] As the lifting rod 32 and the loading tray 33 rise to squeeze the clay into the connecting tube 6, when the bottom end of the lifting rod 32 rises to the vicinity of the second sensor 42, the second sensor 42 transmits a signal to the red light strip, which lights up to remind the staff that the clay in the barrel 2 is about to run out. When the bottom end of the lifting rod 32 rises to the vicinity of the first sensor 41, it indicates that the lifting rod 32 in the barrel 2 has been completely used up, and the first sensor 41 transmits a signal to the driver 72, thereby controlling the clay 3D printer to stop working.

[0042] The utility model is described above by way of example in conjunction with the accompanying drawings. It is obvious that the specific implementation of the utility model is not limited to the above-mentioned method. As long as various non-substantial improvements are made using the method concept and technical solution of the utility model, or the concept and technical solution of the utility model are directly applied to other occasions without improvement, they are all protected by the utility model.
