[0015] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are: 1. In the present invention, by providing a heating component, the fitting plate cooperates with the second spring to drive the moving rod and the pressing block to reciprocate periodically in the sealed box. In cooperation with the intake pipe, the air collecting hood, the connecting pipe and the heating plate, unidirectional conveyance of the hot air in the main body of the firing furnace can be achieved, enabling the hot air to heat and raise the temperature of the bottom of the ceramic tile blank through the heating plate. By heating the bottom of the blank directionally and efficiently through the heating plate, the internal stress difference in the blank caused by gravity can be alleviated, enabling the bottom to quickly reach the sintering temperature and be preliminarily solidified to form a stable support layer, reducing the risk of deformation or cracking caused by uneven shrinkage. Forcing the unidirectional flow of the hot air and concentrating it at the bottom of the blank reduces heat dissipation and improves the utilization rate of thermal energy. Moreover, the preferential heating of the bottom can adjust the distribution of thermal stress inside the blank, avoiding defects such as cracking and warping caused by excessive temperature difference between the upper and lower layers, ensuring that the structure of the blank is uniform and dense, and improving the quality of the finished product.

[0016] 2. In the present invention, by providing a flipping balance component, the driving motor drives the rotating disc and the connecting frame to rotate. Moreover, the gear system composed of the second gear, the first gear and the fixed ring enables the first gear to be driven in the same ratio as the fixed gear ring. The first gear drives the balance plate to rotate and keeps the balance plate always in a horizontal state, so that the ceramic tile blank placed thereon does not shift or tilt during rotation, avoiding deformation or breakage caused by the movement of the blank. At the same time, the uniform compound movement of the rotation and revolution of the balance plate, combined with the temperature control system of the main body of the firing furnace, ensures that all surfaces of the ceramic tile blank are heated evenly, reduces the concentration of thermal stress, and significantly improves the density, flatness and yield of the fired ceramic tile. This device is particularly suitable for the firing process of high-precision ceramic tile samples.

[0017] 3. In the present invention, by providing a stabilizing component, the forward and reverse lead screw cooperates with the rotating rod and the sleeve to drive the movable placement plate to move, so that the distance between the two placement plates meets the placement requirements of the ceramic tile blank. Then, the staff, through the cooperation of the rotating rod and the sleeve, drives the movable lead screw and the lead screw seat to cooperate with the first telescopic rod to drive the movable plate to move through transmission. The first telescopic rod supports and limits the movable plate, improving the stability of the movement of the movable plate. The movable plate drives the stabilizing plate to stably limit both sides of the ceramic tile blank, ensuring the stability during the firing of the ceramic tile blank, thereby improving the quality of the finished ceramic tile blank. Moreover, through the adjustability of the distance between the two movable placement plates and the stabilizing plate, the firing furnace can be applicable to the firing of ceramic tile blanks of different specifications, improving the applicability of this device.

The pressure block 914 transports the hot air in the firing furnace body 1 to the bottom of the ceramic tile blank through its own reciprocating motion in cooperation with the sealed box 910.

[0023] The implementation method is specifically as follows: By setting the heating component 9, the fitting plate cooperates with the second spring 913 to drive the moving rod 915 and the pressing block 914 to reciprocate periodically in the sealing box 910. Cooperating with the air inlet pipe, the air collecting hood 905, the connecting pipe and the heating plate 901 can realize the unidirectional transportation of the hot air in the firing furnace body 1, so that the hot air heats up the bottom of the ceramic tile blank through the heating plate 901. By heating the bottom of the blank directionally and efficiently through the heating plate 901, the internal stress difference of the blank caused by gravity can be alleviated, the bottom can quickly reach the sintering temperature and be preliminarily solidified to form a stable supporting layer, reducing the risk of deformation or cracking caused by uneven shrinkage. Forcing the unidirectional flow of hot air and concentrating it at the bottom of the blank reduces heat loss and improves the thermal energy utilization rate. Moreover, the priority heating of the bottom can adjust the thermal stress distribution inside the blank, avoiding defects such as cracking and warping caused by too large temperature difference between the upper and lower layers, ensuring that the blank structure is uniform and dense, and improving the finished product quality.

[0024] The flipping and balancing component 7 includes a plurality of first gears 701 distributed in a circumferential array. One side of the first gear 701 is rotationally connected to the connecting frame 12 through a rotating shaft. The other end of the rotating shaft extends to the other side of the connecting frame 12 and is connected to one side of the balance plate 6. One side of the first gear 701 is meshed with a second gear 703. The second gear 703 is rotationally connected to one side of the connecting frame 12 through a connecting shaft. One side of a plurality of second gears 703 away from the first gear 701 is meshed with the same fixed gear ring 704. The fixed gear ring 704 is connected to one side of the mounting frame 4. The number of teeth, module and pitch circle radius of the first gear 701 and the fixed gear ring 704 are the same. One side of the mounting frame 4 is fixedly installed with a driving motor 702 through a mounting plate. One end of the output shaft of the driving motor 702 is connected with a transmission shaft. The other end of the transmission shaft extends to the other side of the mounting frame 4 and is connected to one side of the rotating disc 13. The fixed gear ring 704 is sleeved outside the transmission shaft, and there is a gap between the two.

[0025] The implementation method is specifically as follows: By setting the flipping and balancing component 7, the driving motor 702 drives the rotating disc 13 and the connecting frame 12 to rotate. Moreover, the gear system composed of the second gear 703, the first gear 701 and the fixed ring 903 enables the first gear 701 and the fixed gear ring 704 to be driven in the same ratio. The first gear 701 drives the balance plate 6 to rotate and keeps the balance plate 6 always in a horizontal state, so that the ceramic tile blank placed thereon does not shift or tilt during the rotation process, avoiding deformation or breakage caused by the movement of the blank. At the same time, the uniform compound movement of the uniform rotation and revolution of the balance plate 6, combined with the temperature control system of the firing furnace body 1, ensures that the surfaces of the ceramic tile blank are heated evenly, reduces the concentration of thermal stress, and significantly improves the density, flatness and finished product rate of the fired ceramic tile. This device is particularly suitable for the firing process of high-precision ceramic tile samples.

[0026] The stabilizing component 8 includes two symmetrically arranged fixed seats, the fixed seats are connected to the top of the balance plate 6, a positive and negative lead screw 803 and a rotating rod 806 are respectively rotatably connected between the two fixed seats, two symmetrically arranged movable placement plates 801 are threadedly connected to the outer surface of the positive and negative lead screw 803, a sleeve 807 is rotatably connected to the other side of the movable placement plate 801, the rotating rod 806 is sleeved in the sleeve 807, a movable lead screw is rotatably connected to one side of the movable placement plate 801, a lead screw seat 809 is threadedly connected to one side of the movable lead screw, the other end of the lead screw seat 809 is connected to a movable plate 811, a plurality of stabilizing plates 802 are connected to the top of the movable plate 811, a driving wheel 808 is connected to the outer surface of the sleeve 807, one end of the movable lead screw away from the lead screw seat 809 extends to the other side of the movable placement plate 801 and is connected to a driven wheel 804, a transmission belt 805 is connected between the driving wheel 808 and the driven wheel 804, first telescopic rods 810 are arranged on both sides of the lead screw seat 809, and both ends of the first telescopic rods 810 are respectively connected to one side of the movable placement plate 801 and one side of the movable plate 811, and the positive and negative lead screw 803 is symmetrically arranged along the central position, and the thread directions on both sides are opposite.

[0027] The specific implementation method is as follows: By setting the stabilizing component 8, the positive and negative lead screw 803 cooperates with the rotating rod 806 and the sleeve 807 to drive the movable placement plate 801 to move, so that the distance between the two placement plates meets the placement requirements of the ceramic tile blanks. After that, the staff, through the cooperation of the rotating rod 806 and the sleeve 807, through transmission, makes the movable lead screw cooperate with the lead screw seat 809 to drive the movable plate 811 to move with the first telescopic rods 810. The first telescopic rods 810 support and limit the movable plate 811, improving the stability of the movement of the movable plate 811. The movable plate 811 drives the stabilizing plates 802 to stably limit both sides of the ceramic tile blank, ensuring the stability during the firing of the ceramic tile blank, thereby improving the quality of the ceramic tile blank after being formed. And through the adjustability of the distance between the two movable placement plates 801 and the stabilizing plates 802, the firing furnace can be applicable to the firing of ceramic tile blanks of different specifications, improving the applicability of the device.

[0028] Working principle: When in use, the staff member opens the heat preservation door 2 and pushes out the push plate 5 through the electric push rod 11. The staff member places the ceramic tile blank on the stable component 8. Before that, the staff member adjusts the distance between the two movable placement plates 801 according to the actual size of the ceramic tile blank. The staff member rotates the rotation knob to drive the forward and reverse lead screw 803 to rotate. The forward and reverse lead screw 803 cooperates with the rotating rod 806 and the sleeve 807 to drive the movable placement plate 801 to move, so that the distance between the two placement plates meets the placement requirements of the ceramic tile blank. The cooperation between the rotating rod 806 and the sleeve 807 can stably limit the movement of the movable placement plate 801 and improve the stability of the movable placement plate 801 during movement. After that, the staff member places the ceramic tile blank on the tops of the two movable placement plates 801. Then, the staff member rotates the knob. The knob drives the rotating rod 806 to rotate. The rotating rod 806 drives the sleeve 807 to rotate. The sleeve 807 drives the driving wheel 808 to rotate. The driving wheel 808 drives the driven wheel 804 to rotate through the transmission belt 805. The driven wheel 804 drives the moving lead screw to rotate. The moving lead screw drives the lead screw to move. The lead screw seat 809 cooperates with the first telescopic rod 810 to drive the moving plate 811 to move. The first telescopic rod 810 supports and limits the moving plate 811 and improves the stability of the moving plate 811 during movement. The moving plate 811 drives the stabilizing plate 802 to stably limit both sides of the ceramic tile blank, ensuring the stability of the ceramic tile blank during firing, thereby improving the quality of the ceramic tile blank after being finished. And due to the adjustability of the distance between the two movable placement plates 801 and the stabilizing plate 802, the firing furnace can be applicable to the firing of ceramic tile blanks of different specifications, improving the applicability of the device.

[0029] After the stable placement of the ceramic tile blank is completed, the staff member sends the ceramic tile blank back into the firing furnace main body 1 through the electric push rod 11 and the push plate 5. The staff member controls the temperature inside the firing furnace main body 1 by operating the control panel 3. During the firing process, the drive motor 702 is started. The drive motor 702 is a high-temperature resistant motor. The drive motor 702 drives the rotating disc 13 to rotate. The rotating disc 13 drives the connecting frame 12 to rotate. During the rotation process, the second gear 703 revolves around the fixed tooth ring 704, causing the second gear 703 to rotate on its own axis. The second gear 703 drives the first gear 701 to rotate. Since the number of teeth, module, and pitch circle radius of the first gear 701 and the fixed tooth ring 704 are the same, the first gear 701 and the fixed tooth ring 704 are driven in the same ratio. The first gear 701 drives the balance plate 6 to rotate and keeps the balance plate 6 always in a horizontal state. Through the gear system composed of the first gear 701, the second gear 703, and the fixed tooth ring 704, the balance plate 6 is always in a horizontal state.

[0030] During the firing process, since the balance plate 6 always rotates relative to the connecting frame 12, the extrusion wheel 904 periodically contacts the extrusion block 902, and cooperates with the first spring 911 to drive the sliding rod 909 to reciprocate, and the sliding rod 909 drives the sliding plate 906 to reciprocate, and the sliding plate 906 drives the bonding plate to reciprocate, and the bonding plate cooperates with the second spring 913 to drive the moving rod 915 to reciprocate, and the moving rod 915 drives the pressure block 914 to reciprocate periodically in the sealing box 910, and cooperates with the air inlet pipe, the air collecting hood 905, the connecting pipe and the heating plate 901 to realize the one-way transportation of hot air in the firing furnace body 1, so that the hot air is heated to the bottom of the tile blank through the heating plate 901, thereby accelerating the forming speed of the bottom surface of the tile blank.
