[0046] The forming mechanism 1 can alternately press the raw materials into bricks with rectangular and right-angled triangle structures, or simultaneously press the raw materials into bricks with rectangular and right-angled triangle structures, depending on the brick shape required for the stacking process;

[0047] The two opposite sides of the rectangular brick 6 are respectively provided with a first convex strip 61 and a first concave strip 62, and the two right-angled sides of the right-angled triangle brick 7 are respectively provided with a second convex strip 71 and a second concave strip 72, so as to increase the stability of the stacking between the refractory bricks;

[0048] The stacking mechanism 3 drives the bricks to flip, translate and lift, adjusts the position of the bricks, and stacks the bricks of different shapes on the platform mechanism 4 in combination, so that the bricks of different shapes stacked on the platform mechanism 4 can fit the space inside the kiln 5, and the internal space of the kiln 5 can be reasonably used, so that the kiln 5 can burn more bricks in a single operation, thereby improving the working efficiency of the kiln 5 and saving energy consumption.

[0049] In this embodiment, by cooperating with the transfer mechanism 2 and the stacking mechanism 3, on the one hand, for the kiln with an arched structure inner cavity, when only rectangular bricks are stacked for drying, the upper part and the two side parts cannot be fully filled with rectangular bricks. In order to make full use of the space, right-angled triangular bricks can be filled, that is, rectangular bricks and right-angled triangular bricks are stacked and arranged in a combined manner, and the internal space of the kiln 5 is reasonably utilized to achieve full utilization of energy consumption. The special combined arrangement method also further improves the drying efficiency and the stability of brick stacking during the drying process; on the other hand, it can automatically drive the bricks to flip, translate and lift, adjust the position of the bricks, and facilitate the stacking and arrangement of the bricks in different postures on the platform mechanism 4. It has a high degree of automation and can mass-produce zirconia bricks.

[0050] In detail, first, a quantitative amount of raw materials is injected into the mold assembly 13 manually or through an existing robotic arm, the pressing assembly 12 presses the raw materials into refractory bricks of different shapes, and the demolding assembly 14 drives the bricks to be demolded; then, the transfer mechanism 2 successively and alternately receives the bricks of different shapes and completes the transfer of the bricks; then, the stacking mechanism 3 drives the bricks to flip, translate and lift, adjusts the body position and location of the bricks, and stacks the bricks of different shapes on the platform mechanism 4 in combination, and the padding assembly 33 evenly sprinkles the waste brick powder in the gap between the stacked rectangular bricks and the right-angled triangle bricks to prevent the right-angled triangle bricks from damaging the first convex strip 61 of the rectangular bricks, so that the bricks of different shapes stacked on the platform mechanism 4 can adapt to the space inside the kiln 5 and reasonably utilize the space inside the kiln 5; finally, the platform mechanism 4 drives the carrier plate 45 to carry the bricks of different shapes into the space inside the kiln 5, and blocks the entrance of the kiln 5 to uniformly burn the bricks.

[0051] Further, if Figure 1-Figure 7 As shown, the molding mechanism 1 includes a frame 11, a pressing assembly 12 arranged on the frame 11, a mold assembly 13 arranged on the frame 11, and a demoulding assembly 14 arranged on the mold assembly 13;

[0052] The pressing assembly 12 includes a second hydraulic component 121 disposed on the frame 11, a connecting plate disposed on the output shaft of the second hydraulic component 121, a rectangular pressing block 122 disposed at the bottom of the connecting plate and located directly above the first die 134, a fifth concave strip 123 disposed on one side of the rectangular pressing block 122, a sixth convex strip 124 disposed on the other side of the rectangular pressing block 122, a sixth concave strip 125 disposed at the bottom of the rectangular pressing block 122, a triangular pressing block 126 disposed at the bottom of the connecting plate and located directly above the second die 1393, a belt 127 embedded and rotatably disposed on the peripheral side of the triangular pressing block 126, a roller embedded and rotatably disposed inside the triangular pressing block 126 and used to drive the belt 127 to turn, and a second motor 128 disposed inside the triangular pressing block 126 and used to drive a roller;

[0053] The mold assembly 13 includes a frame 131 arranged on the frame 11, a first mold frame 132 arranged inside the frame 131 and used for forming rectangular bricks 6, a first template 133 slidably arranged between the inner side walls of the first mold frame 132, a first mold opening 134 arranged through the frame 131 and located inside the first mold frame 132 and matching the rectangular bricks 6, two groups of first hanging buckles 135 symmetrically arranged at the bottom of the frame 131, a first bottom plate 136 slidably arranged between the two first hanging buckles 135 and matching the first mold opening 134, a third concave strip 137 opened on the inner side wall of the first mold frame 132, a third convex strip 138 arranged on the inner side wall of the first mold frame 132 opposite to the other inner side wall, and a third mold opening 134 arranged on the inner side wall of the first mold frame 132. The fourth convex strip 139 on the first bottom plate 136, the second mold frame 1391 arranged inside the frame 131 and used for forming the right-angled triangle brick 7, the second template 1392 slidably arranged between the inner walls of the second mold frame 1391, the second mold opening 1393 which is set through the frame 131 and located inside the second mold frame 1391 and matches the right-angled triangle brick, two groups of second hanging buckles 1394 symmetrically arranged at the bottom of the frame 131, the second bottom plate 1395 which is slidably arranged between the two second hanging buckles 1394 and matches the second mold opening 1393, the fourth concave strip 1396 arranged on the inner wall of the second mold frame 1391 and the fifth convex strip 1397 arranged on the second bottom plate 1395.

[0054] It should be noted that the pressing component 12 can press rectangular bricks and right-angled triangle bricks at the same time, or can press rectangular bricks and right-angled triangle bricks separately. When it is necessary to press rectangular bricks and right-angled triangle bricks at the same time, the raw materials are injected into the first mold frame 132 and the second mold frame 1391 respectively, and the rectangular pressing block 122 and the triangular pressing block 126 press the raw materials in the first mold frame 132 and the second mold frame 1391 into rectangular bricks and right-angled triangle bricks respectively. When it is necessary to press rectangular bricks or right-angled triangle bricks separately, the raw materials are injected into the first mold frame 132 or the second mold frame 1391 separately, and the rectangular pressing block 122 or the triangular pressing block 126 presses the raw materials in the first mold frame 132 or the second mold frame 1391 separately into rectangular bricks or right-angled triangle bricks.

[0055] It is worth mentioning that when the triangular pressing block 126 is pressing the right-angled triangle brick blank, the triangular pressing block 126 gradually descends in the second mold frame 1391. At the same time, the second motor 128 drives the belt 127 on the outer edge of the triangular pressing block 126 to work. The belt 127 transports the raw material on one side of the second mold frame 1391 obliquely upward to the other side, until the raw material inside the second mold frame 1391 is pressed into a right-angled triangle brick blank.

[0056] In this embodiment, by cooperating with the setting of the pressing component 12 and the mold component 13, on the one hand, the raw materials can be pressed into rectangular bricks or right-angled triangle bricks individually, or the raw materials can be pressed into rectangular bricks or right-angled triangle bricks at the same time, and the shape of the bricks required for the stacking process can be selected, thereby improving the efficiency of brick pressing; on the other hand, when pressing right-angled triangle bricks, the raw materials on one side of the inside of the second mold frame 1391 can be transported obliquely upward to the other side, which facilitates the molding of right-angled triangle bricks and improves the molding effect of right-angled triangle bricks.

[0057] In detail, a certain amount of raw materials is injected into the first mold frame 132 or the second mold frame 1391 manually or through an existing robotic arm, and the second hydraulic component 121 drives the connecting plate with the rectangular pressing block 122 and the triangular pressing block 126 to descend simultaneously, and the rectangular pressing block 122 descends into the first mold frame 132 to press the raw materials into rectangular bricks, or the triangular pressing block 126 descends into the second mold frame 1391, and at the same time, the second motor 128 drives the belt 127 on the outer edge of the triangular pressing block 126 to work, and the belt 127 transports the raw materials on one side of the inside of the second mold frame 1391 obliquely upward to the other side, until the raw materials inside the second mold frame 1391 are pressed into right-angled triangle bricks. Finally, the second hydraulic component 121 drives the connecting plate with the rectangular pressing block 122 and the triangular pressing block 126 to rise and reset simultaneously for next use.

[0058] Further, if Figure 6-Figure 7 As shown, the demolding assembly 14 includes a first motor 141 arranged inside the frame 131, an elliptical disk 142 arranged on the output shaft of the first motor 141, two groups of blocks 143 respectively arranged on the first template 133 and the second template 1392 and slidingly matched with the edge of the elliptical disk 142, and two groups of first hydraulic parts 144 arranged at the bottom of the frame 131 and used to drive the first base plate 136 and the second base plate 1395 to translate respectively.

[0059] In this embodiment, the demoulding assembly 14 is provided to facilitate rapid demoulding of the rectangular bricks and right-angled triangle bricks after being pressed.

[0060] In detail, after the rectangular brick or the right-angled triangle brick is pressed into shape, the first motor 141 drives the elliptical disk 142 to rotate a certain angle, so that the elliptical disk 142 drives the first template 133 and the second template 1392 to approach each other through the block 143 to open the first mold frame 132 and the second mold frame 1391, and then, the first hydraulic component 144 drives the first bottom plate 136 and the second bottom plate 1395 to translate to open the first mold opening 134 and the second mold opening 1393.

[0061] Further, if Figure 1-Figure 2 and Figure 7-Figure 13As shown, the stacking mechanism 3 includes a lifting assembly 31 arranged on the frame 11, a flip assembly 32 arranged on the lifting assembly 31, and a padding assembly 33 arranged on the frame 11;

[0062] The lifting assembly 31 includes two sets of first screw rods 311 arranged on the frame 11, a lifting block 312 threadedly arranged on the first screw rods 311, and a third motor 313 arranged on the frame 11 and used to drive the first screw rods 311;

[0063] The transfer mechanism 2 includes a fifth motor 21 arranged on the moving block 325, a U-shaped frame 22 arranged on the output shaft of the fifth motor 21, a sixth motor 23 arranged on a side wall of the U-shaped frame 22, an electric clamp 24 arranged on the output shaft of the sixth motor 23, a vertical hole opened on the other side wall of the U-shaped frame 22, a third screw rod 25 rotatably arranged inside the vertical hole, a slider 26 threadedly arranged on the third screw rod 25, a strip plate 27 arranged on the side of the slider 26, a plurality of groups of vacuum suction cups 28 arranged on the strip plate 27, and a seventh motor 29 arranged at the bottom of the U-shaped frame 22 and used to drive the third screw rod 25.

[0064] It should be noted that the vacuum suction cups 28 are arranged in two rows on the strips 27 to avoid the second concave strips 72 of the right-angled triangle bricks or the first concave strips 62 of the rectangular bricks, and the vacuum suction cups 28 are connected to an existing external vacuum generator through a hose.

[0065] In this embodiment, the lifting assembly 31 cooperates with the transfer mechanism 2 to automatically receive right-angled triangle bricks or rectangular bricks for transfer.

[0066] In detail, after the rectangular brick or the right-angled triangle brick is demolded, the third motor 313 of the lifting assembly 31 drives the first screw rod 311 to rise with the transfer mechanism 2 through the lifting block 312, so that the top of the U-shaped frame 22 is against the bottom of the right-angled triangle brick or the rectangular brick, and the seventh motor 29 drives the third screw rod 25 to rise with the strip 27 through the slider 26 until the vacuum suction cup 28 on the strip 27 sucks the bottom of the right-angled triangle brick or the rectangular brick, and then the seventh motor 29 drives the third screw rod 25 to descend with the right-angled triangle brick or the rectangular brick through the vacuum suction cup 28. When the right-angled triangle brick or the rectangular brick needs to be flipped, the electric clamp 24 clamps the right-angled triangle The vacuum suction cup 28 is separated from the bottom of the right-angled triangle brick or the rectangular brick, and then the sixth motor 23 drives the electric clamp 24 to flip the right-angled triangle brick or the rectangular brick 90 degrees, so as to facilitate the flat stacking of the right-angled triangle brick or the rectangular brick. The sixth motor 23 drives the electric clamp 24 to flip the rectangular brick 180 degrees, so as to flip the rectangular brick up and down to avoid the first convex strip 61 affecting the stability of the rectangular brick stacking. After flipping, the seventh motor 29 drives the third screw rod 25 to rise with the strip 27 through the slider 26 again, so that the vacuum suction cup 28 sucks the right-angled triangle brick or the rectangular brick again for stacking.

[0067] Further, if Figure 2 and Figure 8-Figure 9 As shown, the flip assembly 32 includes a bar frame 321 rotatably arranged between the two lifting blocks 312 through a damper, a gear 322 arranged at the end of the bar frame 321, a rack 323 arranged on the frame 11 and used to drive the gear 322, a second screw rod 324 rotatably arranged inside the bar frame 321, a moving block 325 threadedly arranged on the second screw rod 324, and a fourth motor 326 arranged inside the bar frame 321 and used to drive the second screw rod 324.

[0068] In this embodiment, by cooperating with the turning assembly 32 and the transfer mechanism 2, the bricks can be driven to turn over, translate and lift, adjust the position of the bricks, and combine bricks of different shapes on the platform mechanism 4.

[0069] In detail, after the transfer mechanism 2 transfers the right-angled triangle brick or the rectangular brick, the lifting component 31 drives the bar frame 321 to lower the transfer mechanism 2. When the gear 322 passes the position of the rack 323, the rack 323 drives the gear 322 to rotate the bar frame 321 180 degrees, so that the U-shaped frame 22 of the transfer mechanism 2 opens downward, thereby flipping the right-angled triangle brick or the rectangular brick. Then, the fourth motor 326 drives the second screw rod 324 to translate the right-angled triangle brick or the rectangular brick through the moving block 325 and the U-shaped frame 22. At the same time, the fifth motor 21 can drive the U-shaped frame 22 to rotate with the right-angled triangle brick or the rectangular brick, so that the right-angled triangle brick or the rectangular brick is stacked at a specified position on the supporting plate 45 in a specified position.

[0070] Further, if Figure 1-Figure 2 As shown, the cushioning assembly 33 includes an outer frame 331 arranged on the frame 11, a material box 332 arranged on the outer frame 331 and filled with brick powder, and several groups of automatic injection pipes 333 arranged at the bottom of the material box 332.

[0071] It should be noted that the fired waste brick slag is crushed and then injected into the material box 332 for reuse. This is because after one side of the rectangular brick with the first concave strip 62 is placed on the supporting plate 45, the upper surface of the rectangular brick will have a first convex strip 61. When the right-angled triangle brick is placed flat on the upper surface of the rectangular brick, the first convex strip 61 on the upper surface of the rectangular brick will be deformed by pressure. Therefore, it is necessary to evenly spread the waste brick powder on both sides of the first convex strip 61 on the upper surface of the rectangular brick to support the flat right-angled triangle brick and prevent the first convex strip 61 on the upper surface of the rectangular brick from being damaged.

[0072] It is worth mentioning that after a layer of rectangular bricks are stacked on the carrier plate 45, two right-angled triangular bricks form a rectangular pattern and lie flat on the upper surface of the rectangular bricks in the layer.

[0073] In this embodiment, by cooperating with the cushioning assembly 33 and the platform mechanism 4, on the one hand, waste brick powder can be evenly spread on the stacking of the right-angled triangle brick blanks and the rectangular brick blanks to support the right-angled triangle brick blanks and prevent the first convex strip 61 on the upper surface of the rectangular brick blanks from being damaged, thereby reducing the breakage rate of the brick blanks and improving the integrity of the brick blanks; on the other hand, the spread waste brick powder increases the gap between the right-angled triangle brick blanks and the rectangular brick blanks, preventing the brick blanks from sticking and deforming during the drying process, ensuring uniform heating and improving the firing efficiency of the brick blanks.

[0074] In detail, when rectangular bricks are stacked on the supporting plate 45, the supporting plate 45 gradually moves toward the material box 332, so that the neatly stacked rectangular bricks on the supporting plate 45 gradually move to the lower position of the material box 332, and the automatic injection pipe 333 evenly spreads the waste brick powder on the upper surface of the neatly stacked rectangular bricks in turn.

[0075] Further, if Figure 1 As shown, the platform mechanism 4 includes a base frame 41 arranged on the side of the kiln 5, a fourth screw rod 42 arranged between the base frame 41 and the kiln 5, an eighth motor 43 arranged on the base frame 41 and used to drive the fourth screw rod 42, a support block 44 threadedly arranged on the fourth screw rod 42, a bearing plate 45 arranged on the support block 44, and a sealing door 46 arranged on one side of the bearing plate 45.
