Description

Technical Field

[0001] This utility model relates to the field of brick blank production technology, and in particular to a kiln line for simultaneous feeding of multiple types of brick blanks. Background Technology

[0002] In the production process of architectural ceramic tiles, after the tile blanks are pressed and formed, they need to be sent to a drying kiln for drying to remove moisture and improve the strength of the blanks, preparing them for subsequent glazing and firing processes. In order to improve production efficiency, a multi-layer drying method is usually adopted for the tile blanks. However, when the press malfunctions, the corresponding conveyor line will interrupt the supply of tile blanks, resulting in an empty kiln. An empty kiln will disrupt the stable airflow organization and temperature distribution within the kiln, not only affecting the drying quality of other normal tile blanks in that layer, causing defects such as uneven drying and cracking, but also increasing energy consumption and reducing drying efficiency due to the unbalanced heat distribution.

[0015] In one embodiment of this utility model, such as Figure 1-6As shown, a multi-brick synchronous kiln feeding line includes a first press 11, a second press 12, a third press 13, a first conveying assembly 21, a second conveying assembly 22, a third conveying assembly 23, a fourth conveying assembly 24, a fifth conveying assembly 25, a sixth conveying assembly 26, a diversion assembly 3, a first lifting assembly 4, a second lifting assembly 5, a third lifting assembly 6, and a fourth lifting assembly 7. One end of the first conveying assembly 21 is connected to the first press 11, and the other end of the first conveying assembly 21 is provided with the first lifting assembly 4. The first lifting assembly 4 is used to lift the bricks from the first conveying assembly 21 to one end of the fourth conveying assembly 24, and the other end of the fourth conveying assembly 24 is used to connect to the first layer of the drying kiln. One end of the second conveying assembly 22 is connected to the second press 12, and the other end of the second conveying assembly 22 is provided with the second lifting assembly 7. Component 5; the second lifting component 5 is used to lift the brick blank of the second conveying component 22 to one end of the fifth conveying component 25, and the other end of the fifth conveying component 25 is used to connect to the second layer of the drying kiln; one end of the third conveying component 23 is connected to the third press 13, and the other end of the third conveying component 23 is provided with the third lifting component 6, which is used to lift the brick blank of the third conveying component 23 to one end of the sixth conveying component 26, and the other end of the sixth conveying component 26 is used to connect to the third layer of the drying kiln; one end of the first conveying component 21, one end of the second conveying component 22 and one end of the third conveying component 23 are respectively provided with the fourth lifting component 7, which is used to lift the brick blank to the diversion component 3 or to take bricks from the diversion component 3 and lower them, and the diversion component 3 is used to divert the brick blank. In this embodiment, the number of the first press 11, the second press 12, the third press 13, the first conveying assembly 21, the second conveying assembly 22, the third conveying assembly 23, the first lifting assembly 4, the second lifting assembly 5, and the third lifting assembly 6 are all two, and the number of the fourth lifting assembly 7 is six. The first lifting assembly 4, the second lifting assembly 5, the third lifting assembly 6, and the fourth lifting assembly 7 have the same structure, but they lift the brick blanks to different heights. The first conveying assembly 21, the second conveying assembly 22, the third conveying assembly 23, and the fourth lifting assembly 7 are also different. Component 24, the fifth conveying assembly 25, and the sixth conveying assembly 26 are existing technologies and are all motor-driven conveying roller group structures. Specifically, the first press 11, the second press 12, and the third press 13 produce three types of brick blanks respectively. The two first presses 11 are connected to the fourth conveying assembly 24 through the corresponding first conveying assembly 21 and the first lifting assembly 4. The two second presses 12 are connected to the fifth conveying assembly 25 through the corresponding second conveying assembly 22 and the second lifting assembly 5. The two third presses 13 are connected to the sixth conveying assembly 26 through the corresponding third conveying assembly 23 and the third lifting assembly 6.The diversion component 3 is connected to the first conveying component 21, the second conveying component 22, and the third conveying component 23 respectively via the fourth lifting component 7. Specifically, the diversion component 3 is a motor-driven conveying roller assembly structure. During operation, the two first presses 11 produce brick blanks. The first conveying component 21 conveys the brick blanks from one end to the other. The first lifting component 4 at the other end of the first conveying component 21 lifts the brick blanks to the fourth conveying component 24, which then conveys them to the first layer of the drying kiln. Similarly, the two second presses 12 produce brick blanks. The second conveying component 22 conveys the brick blanks from one end to the other. The second lifting component 5 at the other end of the second conveying component 22 lifts the brick blanks to the first layer of the drying kiln. The fifth conveying assembly 25 conveys the brick blanks to the second layer of the drying kiln. Two third presses 13 produce brick blanks. The third conveying assembly 23 conveys the brick blanks from one end to the other. The third lifting assembly 6 at the other end of the third conveying assembly 23 lifts the brick blanks to the sixth conveying assembly 26, which then conveys them to the third layer of the drying kiln, allowing the drying kiln to dry brick blanks on all three layers simultaneously. Furthermore, if one of the first presses 11 malfunctions, the other first press 11 increases its pressing frequency and lifts the brick blanks to the diversion assembly 3 via the corresponding fourth lifting assembly 7. The diversion assembly 3 then conveys the brick blanks to the first conveying assembly 21 of the malfunctioning first press 11. Above, bricks are taken down via the fourth lifting component 7 and placed into the first conveying component 21 of the faulty first press 11. Similarly, when one of the second presses 12 or the third press 13 fails, the other second press 12 or the third press 13 increases the pressing frequency and replenishes bricks. Preferably, if both first presses 11 fail, the second press 12 or the third press 13 can also replenish bricks to the first conveying component 21 via the diversion component 3, thereby ensuring that brick blanks are continuously conveyed to the three kiln-entry conveying lines of the fourth conveying component 24, the fifth conveying component 25, and the sixth conveying component 26. This prevents one of the kiln-entry conveying lines from being empty, which would cause changes in the airflow and temperature inside the drying kiln, thus affecting the quality and efficiency of brick blank drying. It should be noted that during the brick replenishment process, the corresponding conveying... The conveying speed of the conveying components can be finely adjusted to ensure that the infeeding speed of the three infeeding conveyor lines is the same, achieving the goal of synchronously feeding multiple brick blanks into the kiln. This invention, through the first press 11, second press 12, third press 13, first conveying component 21, second conveying component 22, third conveying component 23, fourth conveying component 24, fifth conveying component 25, sixth conveying component 26, diversion component 3, first lifting component 4, second lifting component 5, third lifting component 6, and fourth lifting component 7, not only achieves multi-line parallel operation, allowing the drying kiln to simultaneously dry multiple layers of brick blanks and improve production efficiency, but also effectively prevents changes in airflow and temperature within the drying kiln due to one infeeding conveyor line being empty.This ensures the quality and efficiency of brick drying, guarantees the stability and continuity of the production process, and reduces losses caused by equipment failure.

[0016] like Figure 2-3 As shown, the first lifting assembly 4 includes a base plate 41, a lifting plate 42, a mounting frame 43, a first pulley 441, a second pulley 442, a conveyor belt 45, a first drive unit 46, and a second drive unit 47. The first drive unit 46 is mounted on the top surface of the base plate 41, and its output end is connected to the lifting plate 42. The first drive unit 46 is used to drive the lifting plate 42 to move up and down. The bottom of the mounting frame 43 is mounted on the lifting plate 42. The first pulley 441 and the second pulley 442 are rotatably mounted on both ends of the top of the mounting frame 43. Both ends of the conveyor belt 45 are mounted on the first pulley 441 and the second pulley 442, respectively. The second drive unit 47 is used to drive the first pulley 441 to rotate. In this embodiment, the first drive unit 46 is a cylinder. There are two mounting brackets 43, two first pulleys 441, two second pulleys 442, two conveyor belts 45, and two drive units 47. The two mounting brackets 43 are respectively mounted on the top surface of the lifting plate 42 and are arranged opposite each other. The first pulley 441 and the second pulley 442 are respectively mounted on the two ends of the top of each mounting bracket 43, and the two ends of the conveyor belt 45 are wound around the first pulley 441 and the second pulley 442. The conveyor belt 45 is specifically located between two adjacent conveyor rollers. When it is necessary to lift the brick blank, the output shaft of the first drive unit 46 extends out. The first drive unit 46 lifts the lifting plate 42 upwards. The lifting plate 42 drives the conveyor belt 45 to move upwards through the mounting frame 43. The two conveyor belts 45 move upwards from the gap between the conveyor rollers, thereby lifting the brick blank. After the lifting plate 42 rises to the set height, the two second drive units 47 drive the corresponding first pulleys 441 to rotate. Under the action of the second pulleys 442, the two conveyor belts 45 transport the brick blank to the fourth conveying assembly 24. After the brick blank has completely entered the fourth conveying assembly 24, the first drive unit 46 drives the lifting plate 42 to descend and reset, preparing for the lifting of the next brick blank.

[0017] like Figure 3-4As shown, the second drive unit 47 includes a second motor 471, a transmission belt 472, a third pulley 473, and a fourth pulley 474. The second motor 471 is mounted on the mounting frame 43. The third pulley 473 is mounted on the output end of the second motor 471. The third pulley 473 is connected to the fourth pulley 474 via the transmission belt 472. The fourth pulley 474 is coaxially arranged with the first pulley 441. The fourth pulley 474, the third pulley 473, and the transmission belt 472 are all located inside the mounting frame 43. In this embodiment, during operation, the second motor 471 drives the third pulley 473 at its output end to rotate. The third pulley 473 drives the fourth pulley 474 to rotate via the transmission belt 472. Because the fourth pulley 474 is coaxially arranged with the first pulley 441, it also drives the first pulley 441 to rotate, which is convenient and quick.

[0018] like Figure 2-3 As shown, the first lifting assembly 4 further includes guide rods 48. One end of the guide rod 48 is installed on the base plate 41, and the other end is installed on the frame of the first conveying assembly 21. The lifting plate 42 is slidably mounted on the guide rods 48. In this embodiment, there are four guide rods 48. One end of each guide rod 48 is installed on the top surface of the base plate 41, and the other end is installed on the frame of the first conveying assembly 21. This connects the base plate 41 and the frame of the first conveying assembly 21 into an integrated structure, preventing misalignment of the first lifting assembly 4. Furthermore, the lifting plate 42 is guided and slid by the guide rods 48, which not only improves the smoothness and stability of the lifting process but also prevents the lifting plate 42 from shifting.

[0019] like Figure 2-3 As shown, the first lifting assembly 4 further includes a height block 491 and a buffer block 492. The height block 491 is installed on the lifting plate 42, and the buffer block 492 is installed on the top of the height block 491. The buffer block 492 can abut against the frame of the first conveying assembly 21. In this embodiment, there are two height blocks 491 and two buffer blocks 492. The two height blocks 491 are respectively installed at both ends of the lifting plate 42, and the buffer blocks 492 are respectively installed on the top of the two height blocks 491. The buffer blocks 492 are made of rubber. When the lifting plate 42 moves upward, the buffer blocks 492 can play the purpose of shock absorption, buffering and limiting. It can not only prevent the second motor 471 from being damaged by rigid collision with the output roller of the first conveying assembly 21, but also, when the lifting plate 42 is about to reach the set height, the rubber buffer blocks 492 can abut against the frame of the first conveying assembly 21, so that the lifting plate 42 can stop slowly and stably, reducing collision noise and vibration.

[0020] like Figure 5-6 As shown, it also includes telescopic components 8. The fourth conveying component 24, the fifth conveying component 25, the sixth conveying component 26, and the diversion component 3 are each equipped with a telescopic component 8. The telescopic components 8 are located above the first lifting component 4, the second lifting component 5, the third lifting component 6, or the fourth lifting component 7. In this embodiment, the number of telescopic components 8 is twelve. The fourth conveying component 24, the fifth conveying component 25, and the sixth conveying component 26 are each equipped with two telescopic components 8, and the diversion component 3 is equipped with six telescopic components 8. When the fourth lifting component 7 lifts the brick blank to the diversion component 3, specifically, the supporting end of the telescopic component 8 retracts, thereby providing clearance space for the brick blank to rise and fall. After the brick blank is lifted above the supporting end of the telescopic component 8, the telescopic end of the telescopic component 8 returns to its original position, and then the fourth lifting component 7 descends a set distance, causing the telescopic component 8 to... The supporting end of the brick blank rests against the bottom surface of the brick blank. Then, the conveyor belt of the fourth lifting component 7 transports the brick blank. After the brick blank is transported away, the fourth lifting component 7 descends and resets. When it is necessary to lower the brick blank to pick it up, the brick blank is transported to the telescopic component 8 and supported by the supporting end of the telescopic component 8. Then, the lifting end of the fourth lifting component 7 moves upward and lifts the brick blank, so that the brick blank is separated from the supporting end of the telescopic component 8. Then, the telescopic end of the telescopic component 8 retracts, and the fourth lifting component 7 drives the brick blank to descend, thereby achieving the purpose of picking up the brick blank from the diversion component 3. After picking up the brick blank, the supporting end of the telescopic component 8 resets.

[0021] like Figure 5-6 As shown, the telescopic assembly 8 includes a mounting plate 81, support rollers 82, and a third drive unit 83; the third drive unit 83 is mounted on the frame of the fourth conveying assembly 24, the frame of the fifth conveying assembly 25, the frame of the sixth conveying assembly 26, or the frame of the diversion assembly 3. The output end of the third drive unit 83 is mounted on the mounting plate 81, and the mounting plate 81 is mounted with a plurality of rotatable support rollers 82. In this embodiment, the third drive unit 83 is a cylinder. The working principle is explained here using the frame of the diversion component 3 as an example. Specifically, the two ends of the diversion component 3 are respectively equipped with telescopic components 8. The two ends of the brick blank are supported by the two sets of telescopic components 8, thereby ensuring the placement stability of the brick blank. Furthermore, the third drive unit 83 is installed on the frame of the diversion component 3. The output end of the third drive unit 83 is equipped with the mounting plate 81. The mounting plate 81 is located inside the frame of the diversion component 3. Each mounting plate 81 is equipped with five support rollers 82. During operation, the extension and retraction of the output end of the third drive unit 82 drives the movement of the support rollers 82, thereby providing sufficient clearance space for the brick blank, which is convenient and quick.
