Description

Technical Field

[0001] The invention relates to the technical field of ceramic firing, and in particular to a ceramic firing system and a use method thereof. Background Art

[0002] In the field of ceramic firing, the temperature uniformity of the firing furnace has always been a key factor affecting the quality of ceramic products.

[0003] However, the heating elements of traditional ceramic firing systems are mostly fixedly installed. During the firing process, heat can only be transferred in a fixed radiation direction. Since the distance between the ceramic blank and the heating element varies at different positions in the furnace, a large local temperature difference will inevitably form. This uneven temperature distribution can easily cause ceramic products to encounter many quality problems during firing. For example, the thermal stress caused by the temperature difference can cause the ceramic to crack, and the product will deform due to uneven local heating, which will not meet the dimensional accuracy requirements. It will also cause uneven color, greatly reducing the yield and aesthetics of ceramic products, making it difficult to meet the growing market demand for high-quality ceramics.

[0015] The method for using the ceramic firing system comprises the following steps:

[0016] S1: placing the ceramic to be fired on the ceramic firing rack, turning on the hot air blower and the resistance heater, the hot air blower generates hot air to blow the heat generated by the resistance heater from bottom to top, so as to heat and fire the ceramic on the ceramic firing rack;

[0017] S2: During heating, the driving motor is also turned on to drive the rotating shaft and the linkage frame to rotate forward and reversely. When the linkage frame rotates forward and reversely, it slides with the first sliding pin through the first sliding through hole and drives the second movable frame, the vertical frame, and the movable adapter frame to move left and right. When the movable adapter frame moves left and right, it drives the adapter shaft and the heat guide plate to rotate. At the same time, the heat guide plate rotates based on the adapter shaft and slides with the fixed slide rod through the sliding through slot, so that the heat guide plate swings left and right based on the adapter shaft as the center, so that the heat is evenly blown left and right, so that the ceramics on the ceramic firing placement rack are evenly heated and fired;

[0018] S3: When the linkage frame rotates forward and reversely, it also slides with the second sliding pin through the second sliding through hole at the bottom, so that the second sliding pin, the first movable frame, the hot air blower and the resistance heater move left and right, so as to evenly heat the ceramics in the ceramic firing furnace left and right;

[0019] S4: During the firing process, the controller controls the operation of the hot air blower, the resistance heater, and the drive motor according to the temperature information sensed by the temperature sensors at various positions, so as to ensure that the heat is transmitted to various positions in the ceramic firing furnace in real time and evenly until the ceramic is fired into a finished product.

[0020] The beneficial effects of the present invention are:

[0021] 1. In the present invention, the hot air generated by the hot air blower will blow the heat generated by the resistance heater from bottom to top, so as to heat and fire the ceramics on the ceramic firing placement rack; at the same time, the driving motor drives the shaft to rotate forward and reverse, so that the linkage frame rotates forward and reverse based on the shaft. When the linkage frame rotates forward and reverse, it will slide with the first sliding pin through the first sliding through hole and drive the second movable frame, the vertical frame, and the movable adapter frame to move left and right, so that the heat guide plate can swing left and right based on the adapter shaft. In this way, through the left and right swing of the heat guide plate, the heat heated in the furnace can be blown evenly from bottom to top, so that the ceramics on the ceramic firing placement rack can be evenly heated and fired;

[0022] 2. In the present invention, when the linkage frame rotates forward and reversely, the second sliding through hole at the bottom can slide and cooperate with the second sliding pin, so that the first movable frame can move left and right and drive the hot air blower and the resistance heater to move left and right. In this way, the ceramic firing furnace can be evenly heated left and right by changing the heating source position of the hot air blower and the resistance heater, so that the heat can be more evenly distributed in the furnace, ensuring that the ceramic is heated more fully and evenly, which greatly guarantees the quality of ceramic firing;

[0023] 3. In the present invention, only one driving motor is needed to realize the left-right adjustment of the position of the heating source such as the hot air blower and the resistance heater, and also realizes the two functional effects of the heat guide plate swinging and guiding the heat evenly to the left and right, so as to ensure that the ceramic is heated more evenly during firing and the firing effect is better;

[0024] 4. In the present invention, during the firing process, a temperature sensor is also set, and the controller will control the start and stop of the hot air blower and the resistance heater and the forward and reverse working stroke of the drive motor according to the temperature information sensed by the temperature sensor at each position, so as to ensure that the heat heated by the hot air blower and the resistance heater can be transmitted to each position in real time and evenly, avoiding the heating elements in the previous ceramic firing system mostly adopting a fixed installation mode, resulting in the heat in the firing process can only be transmitted in a fixed radiation direction, thereby causing uneven temperature distribution of the ceramic body at different positions in the furnace, thereby causing ceramic products to encounter many quality problems during firing. Ultimately, it can improve the yield and aesthetics of ceramic products, ensure better overall use effect, and be suitable for promotion and use. BRIEF DESCRIPTION OF THE DRAWINGS
