All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1 to 3, a 3D printer for strengthening and toughening a ceramic skeleton for metal treatment includes a table 1, a fixing plate 2 is fixedly installed below the table 1, and the position of the fixing plate 2 is fixed, a base 3 is fixedly connected to the upper surface of the fixing plate 2, current control devices are disposed in the base 3 and the fixing plate 2, a connecting pipe 4 is fixedly connected to the upper surface of the base 3, and the upper end of the connecting pipe 4 is located in the middle of the table 1, so that the connecting pipe 4 can move up and down relative to the table 1 when the table 1 moves up and down, a sealing block 5 is fixedly connected to the middle of the upper surface of the table 1, the sealing block 5 is made of rubber material, and the upper surface is sealed, so that when an auxiliary connecting mechanism is not normally used, the upper surface of the table 1 can be in a planar state, thereby ensuring the integrity of an initially ejected material, the upper end of the connecting pipe 4 is movably connected with a conical block 6 positioned below the sealing block 5, so that when the auxiliary connecting mechanism works normally, after the workbench 1 moves downwards for a certain distance, the connecting pipe 4 drives the conical block 6 to move upwards relative to the workbench 1, materials sprayed on the surface of the workbench 1 are penetrated through the conical block 6, meanwhile, the workbench 1 gradually moves downwards along with the materials sprayed layer by layer, the conical block 6 penetrates through the materials layer by layer, a connecting cavity 9 is arranged in the inner cavity of the connecting pipe 4, the middle part of the connecting cavity 9 is communicated with the outside through a groove in the side surface of the connecting pipe 4, so that the materials can flow into the connecting cavity 9 under the action of the communication between the connecting cavity 9 and the outside while the conical block 6 and the connecting pipe 4 penetrate through the multiple layers of materials, and the materials positioned at the inner side of the materials and with slower solidification rate are bonded together, thereby improving the bonding tightness degree between each layer of the model.

Referring to fig. 2-3, a conductive block 10 is fixedly connected to the middle of a connection tube 4, an N-type material 11 is disposed at the upper end of the connection tube 4 and above the conductive block 10 at one side, a P-type material 12 is disposed at the upper end of the connection tube 4 and above the conductive block 10 at the other side, the lower ends of the N-type material 11 and the P-type material 12 are both in contact with the conductive block 10, a contact block 13 is fixedly mounted at the middle of the tapered block 6, the contact block 13 is in contact with the upper ends of the N-type material 11 and the P-type material 12, the connection tube 4 is made of a ceramic material, so that when the conductive block 10 is energized, when current flows in the order of the conductive block 10, the P-type material 12, the contact block 13, the N-type material 11 and the conductive block 10 at the other side, the connection tube 4 can gradually absorb heat under the peltier effect, thereby increasing the solidification rate of the lower-layer material in contact therewith, and the outer surface of the conical block 6 can release heat synchronously, so that when the conical block 6 in the auxiliary connecting mechanism gradually penetrates through each layer of material, the loss of the material is further reduced, and the integrity of the material in the normal working process of the auxiliary connecting mechanism is further ensured.

Referring to fig. 1, after the mold is machined, the temperature inside and outside the conductive block 10 can be gradually raised by changing the flowing direction of the current, so that the material contacting the inner and outer walls of the connecting pipe 4 is gradually softened, and the material inside the connecting cavity 9 is softened and further bonded, thereby further enhancing the connection efficiency of the auxiliary connecting mechanism, and the separation efficiency between the connecting pipe 4 and the mold can be further improved when the worktable 1 moves upwards, thereby preventing the connecting pipe 4 from being unable to be separated from the mold or the mold from deforming during the separation process.

Referring to fig. 3, the middle of the connecting pipe 4 is movably connected with a supporting block 7 located below the sealing block 5, the middle of the supporting block 7 has the same diameter as the inner cavity of the connecting cavity 9, and the bottom surface of the supporting block 7 is movably connected with the bottom surface of the inner cavity of the workbench 1 through a spring 8, so that when the auxiliary connecting mechanism works normally, the supporting block 7 can automatically move to the middle of the sealing block 5 under the action of the spring 8, and thus when the auxiliary connecting mechanism works normally, the surface of the workbench 1 can always keep a complete horizontal state, and the situation that the material in a molten state drips downwards through the connecting cavity 9 is avoided.

Referring to fig. 2, the connection between the connecting pipe 4 and the conical block 6 is made of rubber, and the outward rotation angle is zero to thirty degrees, so that when the model is taken out, the connecting pipe 4 and the conical block 6 move downwards relative to the model by the upward movement of the workbench 1, and the conical block 6 can be deformed under the action of the rubber at the connection between the connecting pipe 4 and the conical block 6, so that the connecting structure between the material in the connecting cavity 9 and the material outside the connecting cavity is not damaged, thereby ensuring the tightness between the material in the connecting cavity 9 and the material on the outer surface of the connecting pipe 4.

The using method of the invention is as follows:

auxiliary connection: when the three-dimensional inkjet printer normally works, every blowout one deck material, workstation 1 just descends the one deck for toper piece 6 upwards stretches out for workstation 1 under the effect of connecting pipe 4 and fixed plate 2, thereby makes the middle part of toper piece 6 upper end through the material, and descends along with workstation 1 gradually, runs through every layer of material, thereby makes the material can condense together through connecting chamber 9, and then increases the inseparable degree of condensing of model.

And (3) cooling the lower layer: when the three-dimensional printer normally works, the model is connected in an auxiliary mode through the auxiliary connecting mechanism, under the effect of electrifying the conductive block 10, current flows through the conductive block 10, the P-type material 12, the contact block 13, the N-type material 11 and the conductive block 10 on the other side in sequence, so that heat is absorbed by the inner side and the outer side of the conductive block 10 under the effect of the Peltier effect, and the solidification rate of the lower-layer material is accelerated.

At the normal during operation of lower floor's cooling body, under the effect of Peltier effect, the outside temperature of contact block 13 risees gradually, thereby make toper piece 6 deepen the material inside gradually, the resistance that receives is less, thereby avoided causing the condition of destruction to the material shape to take place, and after accomplishing the processing, can flow through the direction through the change electric current, make conducting block 10 inside and outside temperature rise gradually, thereby make the material with the contact of connecting pipe 4 inside and outside wall soften gradually, and then make when the model takes out, can not destroyed by auxiliary connection mechanism, the inseparable degree of connection of material in the chamber 9 is connected in the while further strengthening.
