Description

Technical Field

[0001] This utility model relates to the field of porcelain firing technology, and in particular to a firing device for large-scale decorative porcelain. Background Technology

[0002] Large decorative porcelain pieces, such as large vases, porcelain paintings, and sculptures, require extremely high stability during firing due to their size, weight, and complex shapes. Traditional kiln firing methods typically involve placing the porcelain pieces on kiln cars or firing plates and then pushing them into the kiln. For large porcelain pieces, slight wobbling or vibration is inevitable during movement. This instability can easily cause the porcelain to tip over, collide, or suffer internal stress damage during firing, resulting in low yields or even the complete loss of the piece.

[0003] In existing technologies, such as the porcelain feeding and pushing device disclosed in patent CN218179656U, the automated conveying of porcelain is achieved by setting up a moving carrier. However, the core of such devices lies in the carrier moving and the kiln remaining stationary. When carrying large porcelain pieces, the carrier and the porcelain on it move a long distance on the track. Any unevenness, gaps at the track interface, or minor impacts from the drive system during the process can be amplified into harmful vibrations to the porcelain. Especially before and after firing, when the porcelain is at room temperature and its texture is fragile, it is more sensitive to shaking. Therefore, a firing device for large decorative porcelain is needed to meet people's needs. Utility Model Content

[0004] The purpose of this invention is to provide a firing apparatus for large-scale decorative porcelain, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a firing device for large-scale decorative porcelain, comprising a firing carrier, a support frame, a kiln, and a linear track.

[0006] The firing carrier is fixed on the ground, and the top is a flat refractory platform for placing porcelain. Since the firing carrier itself is fixed, the porcelain does not need to be moved from the time it is placed on it until it is removed after firing, thus fundamentally eliminating the risk of shaking caused by the movement of the carrier.

[0007] The kiln has an open bottom and one open end. The bottom opening is used to accommodate the firing medium, and the end opening is used to open and close the hatch to allow porcelain to be placed in and taken out. The kiln is lined with high-performance insulation materials and a heating system, such as electric heating wires and gas burners, to ensure the temperature environment required for firing.

[0008] The linear track is fixed to the ground, providing precise guidance for the movement of the kiln.

[0009] The support frame is located at the bottom of the kiln and supports the entire kiln. The bottom of the support frame is equipped with track wheels, whose grooves engage with a straight track, ensuring that the kiln can only move horizontally along the track and preventing deviation. To further provide driving force, the support frame is also equipped with heavy-duty wheels driven by a motor. The bottom of the heavy-duty wheels is in direct contact with the ground, and the motor drives the heavy-duty wheels to roll, thereby propelling the entire kiln smoothly along the track.

[0010] Preferably, the firing carrier is constructed of refractory bricks or thermal insulation materials, possessing good load-bearing capacity and thermal stability.

[0011] Preferably, the linear track consists of four sets, all fixed parallel to the ground. Each set is equipped with the same number of track wheels, and every two sets are arranged on the same side of the bottom opening of the kiln, forming a stable double-sided support, which further ensures the stability of the kiln when it moves.

[0012] To optimize the positioning and locking of the kiln after it moves to the working position, this utility model also includes a buffer and locking mechanism. A horizontally arranged insertion hole is pre-installed on the side of the firing carrier facing away from the kiln door. A buffer spring is welded to the end of the insertion hole via a pre-embedded steel plate, and a buffer block is welded to the end of the buffer spring. Correspondingly, a connecting plate is provided on the bottom end of the side of the kiln facing away from the door, and a horizontally arranged plug is provided on one side of the connecting plate. When the kiln moves towards the firing carrier, the plug is inserted into the insertion hole and compresses the buffer spring. The spring's buffering effect absorbs the final impact force when the kiln reaches its position, achieving a flexible connection and avoiding hard collisions that could affect the kiln structure or the porcelain.

[0013] To ensure a tight seal between the kiln and the firing carrier during firing and prevent heat loss, this invention also includes a precise positioning and locking mechanism. A slot is pre-drilled on the side of the firing carrier near the insertion hole. A vertically arranged electric telescopic rod is installed within the slot. A positioning pin is mounted on the telescopic shaft of the electric telescopic rod. When the plug is fully inserted into the insertion hole, the electric telescopic rod is activated, causing the positioning pin to extend upwards and insert into a pre-set positioning hole at the bottom of the plug, thereby locking the plug in the insertion hole and achieving a secure connection between the kiln and the firing carrier.

[0014] To further improve the reliability and automatic alignment of the locking mechanism, a return spring is connected between the telescopic shaft of the electric telescopic rod and the positioning pin. The side of the plug near the insertion hole opening is wedge-shaped. When the plug is inserted, even with slight deviations, the wedge-shaped surface can guide the plug to enter smoothly. If the positioning pin is not fully aligned with the hole on the plug, the return spring provides a certain degree of buffering and self-adaptation, ensuring that locking is eventually completed under the continuous action of the electric telescopic rod.

[0015] The beneficial effects of this utility model are: This invention employs an innovative design of a movable kiln, ensuring that large porcelain pieces remain stationary on a fixed firing platform throughout the entire firing cycle. This completely eliminates any risk of shaking or vibration caused by movement, providing unprecedented stability for the perfect firing of large porcelain pieces. Furthermore, the kiln's movement is driven by a motor, and its positioning and locking are controlled by an electric telescopic rod, facilitating automated operation and reducing manual labor intensity and operational risks.

[0016] The present invention effectively absorbs the impact force when the kiln is in place by setting buffer springs and buffer blocks, so as to achieve smooth docking. The positioning pin locking mechanism driven by electric telescopic rod ensures the firmness of the connection between the kiln and the firing carrier during the firing process, with good sealing and less heat loss.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Reference Figure 1-4A large-scale porcelain firing device includes a firing carrier 1, a support frame 2, a kiln 3, and a linear track 4. The firing carrier 1 is fixed on the ground, and the top is a flat refractory platform for placing porcelain. The kiln 3 is open at both the bottom and one end. The bottom opening is used to accommodate the firing carrier 1, and the end opening is used to open and close the hatch. The interior is lined with high-performance insulation material and a heating system. The linear track 4 is fixed on the ground. The support frame 2 is set on the bottom of the kiln 3. The bottom of the support frame 2 is equipped with a track wheel 5. The groove of the track wheel 5 is engaged with the linear track 4. The support frame 2 is equipped with a heavy-duty wheel 6, which is driven by a motor and whose bottom is in contact with the ground.

[0021] Specifically, in this embodiment, the firing carrier 1 is constructed of refractory bricks or thermal insulation materials.

[0022] Specifically, in this embodiment, there are four sets of linear tracks 4, all of which are fixed parallel to each other on the ground. Each set is equipped with the same number of track wheels 5, and every two sets are arranged on the same side of the bottom opening of the kiln 3.

[0023] Specifically, in this embodiment, a horizontally arranged insertion hole 7 is reserved on the side of the firing carrier 1 away from the kiln 3 door. A buffer spring 8 is welded to the end of the insertion hole 7 through a pre-embedded steel plate. A buffer block 9 is welded to the end of the buffer spring 8. A connecting plate 10 is provided on the bottom end of the side of the kiln 3 away from the door. A horizontally arranged plug 11 is provided on one side of the connecting plate 10. The plug 11 corresponds to the position of the insertion hole 7.

[0024] Specifically, in this embodiment, a slot 12 is reserved on the side of the carrier 1 near the insertion hole 7. A vertically arranged electric telescopic rod 13 is provided in the slot 12. A positioning pin 14 is provided on the telescopic shaft of the electric telescopic rod 13. The positioning pin 14 is inserted into the bottom end of the plug 11 located in the insertion hole 7.

[0025] Specifically, in this embodiment, a return spring 15 is connected between the telescopic shaft of the electric telescopic rod 13 and the positioning pin 14, and the side of the plug 11 near the opening of the insertion hole 7 is wedge-shaped.

[0026] During installation, the firing support 1 is first securely fixed in the predetermined position on the ground. The firing support 1 is made of refractory bricks with a flat platform on top. Four sets of linear tracks 4 are fixed parallel to each other on the ground, with the tracks extending under the firing support 1. The kiln 3 is supported on the tracks by the support frame 2 at its bottom. The grooves of the track wheels 5 at the bottom of the support frame 2 are precisely engaged with the linear tracks 4, and the heavy-duty wheels 6 driven by the motor are in contact with the ground.

[0027] During operation, the large porcelain pieces to be fired are first securely placed on the refractory platform atop the fixed firing carrier 1. Then, the drive motor is started, and the heavy-duty wheels 6 rotate, propelling the entire kiln 3 along the straight track 4 towards the firing carrier 1. As the kiln 3 approaches the firing carrier 1, the plugs 11 at its bottom align and insert into the insertion holes 7 on the firing carrier 1. The wedge-shaped surface at the front end of the plug 11 aids in guidance. During insertion, the end of the plug 11 contacts and compresses the buffer spring 8, absorbing any remaining kinetic energy through the buffer block 9 and the buffer spring 8, allowing the kiln 3 to smoothly and gently enter position.

[0028] After the kiln 3 completely covers the firing carrier 1, the electric telescopic rod 13 is activated, pushing the positioning pin 14 upward. With the assistance of the return spring 15, the positioning pin 14 adaptively inserts into the positioning hole at the top of the plug 11, firmly locking the plug 11 and thus tightly fixing the kiln 3 and the firing carrier 1 together. At this point, the kiln 3 door can be closed, and the heating system can be started for firing.

[0029] After firing, once the kiln 3 has cooled, first retract the electric telescopic rod 13 to unlock the positioning pin 14 from the bolt 11. Then, drive the kiln 3 to move in the opposite direction, detaching it from the firing carrier 1. Finally, the fired porcelain can be safely removed from the stationary firing carrier 1.

[0030] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
