Description

Technical Field

[0001] This utility model relates to the field of ceramic tile production technology, and in particular to a turning device for bricks to be fired. Background Technology

[0002] In the production process of ceramic tiles, powder is first pressed to form shaped tiles, then the surface of the tiles is decorated with glaze, and finally they are fired in a kiln. Current ceramic tile production methods, when producing tiles of different sizes, require multiple kilns for separate production due to kiln width limitations and different feeding methods for large and small tiles. One kiln is dedicated to firing smaller tiles, while another is dedicated to firing larger tiles. This results in high investment and maintenance costs for kiln equipment, and the production lines of different kilns occupy a large area, seriously hindering enterprises from improving efficiency and reducing costs.

[0003] In the existing technology, for a production line that needs to produce products of different specifications, in order to stably support large-sized products, a steering machine is mainly configured on the glazing line to meet the steering needs of different sized tiles. However, because the speed of the steering machine affects the speed of the glazing line, the speed of the glazing line is limited, which affects the production capacity and cannot meet the production needs, and the uneven force applied to the tiles by the lifting or driving force rotation in the middle of the steering machine will also affect the quality of the tiles, leading to problems such as easy cracking, cracking or warping of the tiles. Utility Model Content

[0004] To address the aforementioned shortcomings, the purpose of this utility model is to propose a steering device for bricks to be fired, which solves the problems of uneven force applied to bricks by the current steering mechanism, affecting the quality of ceramic tiles, and the limited production capacity due to the influence of the steering mechanism on the glaze line speed.

[0009] The second transport mechanism includes a brick feeding conveying component, a waiting conveying component, and a brick discharging conveying component. The brick feeding conveying component and the waiting conveying component are arranged side by side, and the conveying direction of the brick feeding conveying component is the same as that of the waiting conveying component. The brick discharging conveying component is vertically mounted on the frame and is arranged to avoid the waiting conveying component. The conveying direction of the brick discharging component is perpendicular to that of the waiting conveying component.

[0010] The frame is equipped with several displacement detectors, which are used to detect the movement of the bricks into position and send the detection signals to the control device.

[0011] Preferably, the feeding end of the first transport mechanism is aligned with the feeding end of the second transport mechanism, and the discharging end of the first transport mechanism is aligned with the discharging end of the second transport mechanism.

[0012] The first transport mechanism and the second transport mechanism are respectively horizontally mounted on the frame.

[0013] Preferably, the overall lifting mechanism includes a base, a lifting drive motor, a transmission chain, and several lifting components. The frame is movably mounted above the base via several of the lifting components. The lifting drive motor is connected to the transmission chain, and the transmission chain is connected to the several lifting components.

[0014] Preferably, the brick feeding conveying assembly and the waiting conveying assembly each include a plurality of conveying rollers, and the plurality of conveying rollers are arranged at intervals;

[0015] The brick conveying assembly includes several conveyor belts, which are arranged in parallel between the conveyor rollers of the waiting conveying assembly. The conveyor belts are vertically mounted on the frame, such that the conveying end face of the conveyor belt is higher or lower than the conveying end face of the waiting conveying assembly.

[0016] Furthermore, a second lifting drive motor is provided at the bottom of each of the four corners of the brick conveying assembly, and the output end of the second lifting drive motor is connected to the bottom of the brick conveying assembly.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0035] The present invention proposes a turning device for bricks to be fired, comprising an integral lifting mechanism 4 and a frame 1. The frame 1 is installed on the lifting end of the integral lifting mechanism 4, and the integral lifting mechanism 4 is used to lift the frame 1 in the vertical direction.

[0036] The frame 1 is equipped with a first transport mechanism 2 and a second transport mechanism 3, and the first transport mechanism 2 and the second transport mechanism 3 are distributed on the frame 1, one above the other;

[0037] The first transport mechanism 2 has a 90° arc-shaped turning transport channel, and the first transport mechanism 2 is used to transport bricks at a 90° turn;

[0038] The second transport mechanism 3 includes a brick feeding conveying component 31, a waiting conveying component 32, and a brick discharging conveying component 33. The brick feeding conveying component 31 and the waiting conveying component 32 are arranged side by side, and the conveying direction of the brick feeding conveying component 31 is consistent with the conveying direction of the waiting conveying component 32. The brick discharging conveying component 33 is vertically mounted on the frame 1 and is arranged to avoid the waiting conveying component 32. The conveying direction of the brick discharging component 33 is perpendicular to the conveying direction of the waiting conveying component 32.

[0039] The frame 1 is equipped with several displacement detectors, which are used to detect the movement of the bricks into position and send the detection signals to the control device.

[0040] To address the problems existing in the prior art, this utility model proposes a turning device for bricks to be fired. This device is used when the bricks to be fed into the kiln are changed from a large size to a smaller size, specifically, from 750×1500mm to 600×1200mm. Figure 6 The method shown involves vertically feeding two small-sized bricks into the kiln. The entire frame 1 is raised via the overall lifting mechanism 4, allowing the bricks to enter the second transport mechanism 3, thus changing the direction of movement and the forward movement of the bricks. When changing from small to large sizes, as... Figure 5 The method shown involves feeding large-sized bricks horizontally into the kiln. The entire frame 1 is lowered via the overall lifting mechanism 4, allowing the bricks to enter the first transport mechanism 2. This changes the direction of brick movement without altering the brick's forward trajectory. The frame 1 is mounted on the lifting end of the overall lifting mechanism 4. The overall lifting mechanism 4 is used to vertically raise and lower the frame 1, switching between the first transport mechanism 2 and the second transport mechanism 3. The overall raising and lowering of the frame 1 allows either the first transport mechanism 2 or the second transport mechanism 3 to be aligned with the entire glaze line, smoothly changing the direction of brick movement and altering or maintaining the forward trajectory of the brick. This ensures the bricks enter the kiln in the desired manner, reducing wasted kiln space and minimizing the impact of uneven force on the bricks, thus guaranteeing a high product yield. Therefore, the overall lifting mechanism 4 moves the first transport mechanism 2 and the second transport mechanism 3 vertically, ensuring the bricks remain balanced during the turning process on the glaze line. This solves the current problems of glaze line speed being affected by the turning mechanism, limited production capacity, and uneven force on the bricks during turning.

[0041] Meanwhile, the second transport mechanism 3 includes a brick feeding conveying component 31, a waiting conveying component 32, and a brick discharging conveying component 33. Bricks pass through the brick feeding conveying component 31 and enter the waiting conveying component 32. The brick discharging conveying component 33, which is arranged to avoid the waiting conveying component 32, rises. Because the conveying direction of the brick discharging component 33 is perpendicular to the conveying direction of the waiting conveying component 32, the brick discharging conveying component 33 changes the forward end of the brick. The operation of the second transport mechanism 3 ensures that small-sized bricks can change their forward end as needed after entering the turning device, which facilitates subsequent parallel arrangement and vertical entry into the kiln.

[0042] In addition, the moving distance of the frame 1 can be determined by specific measurement, and the lifting distance can be determined. During operation, the overall lifting mechanism 4 controls the frame 1 to rise or fall to the corresponding height, so that the first transport mechanism 2 or the second transport mechanism 3 is level with the entire glaze line, ensuring the smooth operation of the brick.

[0043] It is worth noting that the input front end of the steering device is the input line 51, and the output rear end of the steering device is the output line 52. The control device is used to control the operation of the first transport mechanism 2, the second transport mechanism 3, and the overall lifting mechanism 4. When large-sized bricks need to be produced, the control device controls the overall lifting mechanism 4 to rise and fall so that the first transport mechanism 2 is level with the entire glaze line, so that the brick can enter the first transport mechanism 2 from the input line 51, change the direction of movement of the brick and keep the forward end of the brick, and then leave the steering device through the output line 52 and enter the kiln in a horizontal manner. When small-sized bricks need to be produced, the control device controls the overall lifting mechanism 4 to rise and fall so that the second transport mechanism 3 is level with the entire glaze line, and according to the detected brick movement position, when the brick enters the waiting conveying component 32, the waiting conveying component 32 is paused, and the brick output conveying component 33 is controlled to rise and run, driving the brick into the output line 52, so that the brick can enter the kiln in a vertical manner.

[0044] Preferably, the feeding end of the first transport mechanism 2 is aligned with the feeding end of the second transport mechanism 3, and the discharging end of the first transport mechanism 2 is aligned with the discharging end of the second transport mechanism 3.

[0045] The first transport mechanism 2 and the second transport mechanism 3 are respectively horizontally arranged on the frame 1.

[0046] Specifically, each feed end is aligned with the discharge end to ensure that during the lifting process of the overall lifting mechanism 4, the first transport mechanism 2 and the second transport mechanism 3 can cooperate with the input line 51 and the output line 52, preventing the steering device from colliding with the input line 51 and the output line 52 during the lifting process. Furthermore, the steering device is set on the glaze line to keep the first transport mechanism 2 and the second transport mechanism 3 horizontally positioned, effectively keeping the brick horizontal during transportation, ensuring the pass rate of the pattern on the brick surface, and reducing the occurrence of blurred patterns due to brick tilting.

[0047] Preferably, the overall lifting mechanism 4 includes a base 41, a lifting drive motor 42, a transmission chain 43, and several lifting components. The frame 1 is movably mounted above the base 41 via several of the lifting components. The lifting drive motor 42 is connected to the transmission chain 43, and the transmission chain 43 is connected to the several lifting components.

[0048] Specifically, such as Figure 1 and Figure 2 As shown, the overall lifting mechanism 4 includes a lifting drive motor 42, a transmission chain 43, and lifting components. The lifting drive motor 42 is connected to the lifting components through the transmission chain 43, meaning that several lifting components operate synchronously without changing the horizontal state of the steering device, ensuring that the bricks on the steering device remain horizontal, so that the force on each part of the brick is uniform, effectively ensuring the pass rate and quality of the tiles.

[0049] The lifting assembly is located at each outer corner of the bottom of the frame 1 to effectively distribute stress and ensure subsequent adjustment of the frame 1's height. The lifting assembly includes a lead screw 44 and a chain wheel 45. A sprocket is connected to the output end of the lifting drive motor 42. The lifting drive motor 42 is connected to the transmission chain 43 via the sprocket. The transmission chain 43 is connected to the lead screw 44 via the chain wheel 45. A matching nut is provided on the lead screw 44, and the nut is fixedly connected to the frame 1. Specifically, the lifting drive motor 42 drives the sprocket to rotate, and the sprocket is connected to the... The transmission chain 43 connects the sprockets, and the rotation of the sprockets drives the transmission chain 43, which in turn drives the chain discs 45 of each lifting component to rotate. The rotation of the chain discs 45 drives the lead screw 44 to rotate, which in turn drives the nut to move in the vertical direction, thus driving the frame 1 to rise and fall. At the same time, the lead screw 44 can convert the rotational motion into linear motion, precisely controlling the linear displacement, that is, precisely controlling the level of the entire device. Several lead screws 44 are driven by the same transmission chain 43 and rotate synchronously, with the lifting height at each point being completely consistent, so that the first transport mechanism 2 and the second transport mechanism 3 can maintain horizontal up and down movement. Compared with using a chain to drive up and down movement at various points, using the transmission chain 43 to drive the frame 1 to rise and fall effectively reduces the elastic deformation, pitch error and tension difference of the chain itself, and better ensures the level of the transport surface of the first transport mechanism 2 and the second transport mechanism 3.

[0050] In addition, the steering device can be initially calibrated using a laser level.

[0051] Preferably, the brick feeding conveying assembly 31 and the waiting conveying assembly 32 each include a plurality of conveying rollers, and the plurality of conveying rollers are arranged at intervals;

[0052] The brick conveying assembly 33 includes a plurality of conveyor belts 331, which are arranged in parallel between the conveyor rollers of the waiting conveying assembly 32. The plurality of conveyor belts 331 are vertically mounted on the frame 1, such that the conveying end face of the conveyor belts 331 is higher or lower than the conveying end face of the waiting conveying assembly 32.

[0053] Specifically, such as Figure 3 As shown, when the bricks are fully inside the waiting conveying assembly 32, the brick output conveying assembly 33 rises, and the conveying end face of the brick output conveying assembly 33 is higher than the conveying end face of the waiting conveying assembly 32. The bricks are supported by the brick output conveying assembly 33 and move into the output line 52 and then into the kiln, controlling the direction of movement and the forward end of the bricks.

[0054] The brick feeding conveying assembly 31, the waiting conveying assembly 32, and the brick output conveying assembly 33 each include a corresponding drive connection structure, which can be used to drive several conveying rollers to rotate or to drive several conveying belts 331 to rotate. The drive connection structure is existing technology and will not be described in detail here.

[0055] Furthermore, each of the four corners of the brick conveying assembly 33 is provided with a second lifting drive motor 341, and the output end of the second lifting drive motor 341 is connected to the bottom of the brick conveying assembly 33.

[0056] The four second lifting drive motors 341 operate synchronously, driving the brick conveying assembly 33 to rise and fall horizontally as a whole, thereby making the conveyor belt 331 higher or lower than the conveying end face of the waiting conveying assembly 32, ensuring that the bricks can be transported horizontally to the output line 52, while effectively dispersing stress and ensuring the smooth transport of bricks.

[0057] Furthermore, the brick feeding conveying assembly 31 is driven by a first drive motor 311 to rotate the conveying roller, and the waiting conveying assembly 32 is driven by a second drive motor 321 to rotate the conveying roller.

[0058] The displacement detector includes a photoelectric detection switch, which is located above the brick feeding conveying assembly 31 and the waiting conveying assembly 32. The photoelectric detection switch is used to detect the movement of the bricks.

[0059] Specifically, when the first brick enters the brick feeding conveyor 31 and reaches the waiting conveyor 32, under the control of the photoelectric detection switch, the second drive motor 321 stops driving, and the waiting conveyor 32 stops operating. After the brick output conveyor 33 conveys the brick to the output line 52 and descends below the transport end face of the waiting conveyor 32, the second drive motor 321 drives the waiting conveyor 32 to start running again. During the above process, when the end of the second brick reaches the junction of the brick feeding conveyor 31 and the waiting conveyor 32 and the brick output conveyor 33 has not descended, the first drive motor 311 stops driving, and the brick feeding conveyor 31 stops operating until the brick output conveyor 33 descends below the transport end face of the waiting conveyor 32. Then, the first drive motor 311 drives the brick feeding conveyor 31 to start running again. Subsequently, the brick feeding conveyor 31 and the waiting conveyor 32 jointly convey the second brick until it reaches the waiting conveyor 32, and the above process is repeated to change the direction of movement and the forward end of the brick.

[0060] Furthermore, the control device includes a controller, which is electrically connected to the first drive motor 311, the second drive motor 321, the second lifting drive motor 341, and the photoelectric detection switch.

[0061] Specifically, under the control of the controller and in conjunction with the photoelectric detection switch, the operating states of the first drive motor 311, the second drive motor 321, and the second lifting drive motor 341 are changed to ensure the horizontal and stable transport of the second transport mechanism 3 and to realize the automated turning of small-sized bricks.

[0062] Preferably, the first transport mechanism 2 includes an inner pulley group 23, a conveyor belt 21, and an outer pulley group 24. A plurality of the conveyor belts 21 are arranged in a 90° arc array, and the conveyor belts 21 are respectively mounted on the pulleys of the inner pulley group 23 and the pulleys of the outer pulley group 24.

[0063] Specifically, such as Figure 4 As shown, several conveyor belts 21 are arranged in a 90° arc array, causing the bricks to change their direction of movement under the drive of the conveyor belts 21 while maintaining their forward movement. It is worth noting that the rotational speed of the inner pulley group 23 is lower than that of the outer pulley group 24. The inner pulley group 23 and the outer pulley group 24 rotate at different speeds. The inner pulley group 23 is located inside the arc structure. Through the lateral force generated by the speed difference, the bricks smoothly change direction along the arc path, effectively avoiding brick deformation and surface damage.

[0064] Furthermore, the first transport mechanism 2 also includes a plurality of guide wheels 25 on the arc bracket 22, and the inner pulley group 23 and the outer pulley group 24 are rotatably connected to the end of the arc bracket 22;

[0065] The guide wheel 25 is located on the inner side of the conveyor belt 21.

[0066] Specifically, the inner pulley group 23 and the outer pulley group 24 are rotatably connected to the end of the arc support 22, driving the conveyor belt 21 to rotate, thereby causing the brick to turn smoothly, achieving the purpose of changing the direction of brick movement while ensuring conveying stability.

[0067] The arc-shaped support 22 is adapted to the right-angle structure of the second transport mechanism 3. The two ends of the arc-shaped support 22 are aligned with the feed end and discharge end of the second transport mechanism 3 to ensure that the bricks can enter the steering device smoothly and prevent damage caused by collisions between the steering device and other structures during the lifting process.

[0068] Furthermore, the guide wheel 25 is located on the inner side of the transmission belt, that is, the inner side of the arc structure. The guide wheel 25 ensures that the transmission belt runs along the required turning radius and plays a certain guiding role, preventing the direction of the transmission belt 21 from deviating and ensuring that the bricks on it can move in the required direction.

[0069] It is worth noting that the control method applied to the above-mentioned steering device includes the following steps:

[0070] S1. The overall lifting mechanism drives the frame to move vertically;

[0071] Specifically, when the produced product changes from a large size to a small size, the overall lifting mechanism drives the entire frame to rise, allowing the bricks to enter the second transport mechanism; when the produced product changes from a large size to a small size, the overall lifting mechanism drives the entire frame to fall, allowing the bricks to enter the first transport mechanism.

[0072] S2. The first or second transport mechanism changes the direction of movement of the brick and controls the forward end of the brick as needed.

[0073] Wherein: S21, when the brick enters the first transport mechanism, the first transport mechanism conveys the brick, changing the direction of movement of the brick while keeping the forward end unchanged, and the brick enters the kiln horizontally;

[0074] S22. When the brick enters the second transport mechanism, the brick feeding conveying component and the waiting conveying component operate. After the brick as a whole reaches the transport end face of the waiting conveying component, the waiting conveying component stops operating, the brick discharging conveying component rises, and after the brick is transported to leave the turning device, the brick discharging conveying component descends.

[0075] During this period, when the end of the next brick reaches the junction of the brick feeding conveyor and the waiting conveyor and the brick exit conveyor has not descended, the brick feeding conveyor stops running until the transport end face of the brick exit conveyor descends below the transport end face of the waiting conveyor. Then the brick feeding conveyor restarts and repeats the aforementioned step S22, thereby changing the direction of movement and the forward end of the brick.

[0076] The entire process is as follows: pressing bricks yields large-sized bricks (750×1500 mm) and small-sized bricks (600×1200 mm). These bricks pass through a glaze line and enter the turning device. When the desired product size changes from large to small, the brick feeding method changes from horizontal to vertical, and the frame 1 rises. Figure 6 As shown, the second transport mechanism 3 rises until it reaches the corresponding position, and the bricks move towards the second transport mechanism 3, so that the two bricks are vertically fed into the kiln; when the required product is changed from a small size to a large size, the bricks change from vertical to horizontal feeding into the kiln, and the frame 1 descends, as shown. Figure 5 As shown, when the lower transport mechanism descends to the corresponding position and connects with the input line 51, the bricks are then fed into the kiln horizontally.

[0077] The technical principles of this utility model have been described above with reference to specific embodiments. These descriptions are merely for explaining the principles of this utility model and should not be construed as limiting the scope of protection of this utility model in any way. Based on this explanation, those skilled in the art can readily conceive of other specific embodiments of this utility model without any inventive effort, and these embodiments will all fall within the scope of protection of this utility model.
