Description

Technical Field

[0001] The invention relates to a roller kiln, in particular to a roller kiln used for producing ceramic tiles in the technical field of ceramic tile production. Background Art

[0002] As a material widely used in the field of building decoration, the production process of ceramic tiles covers several key links, and the firing link plays a core role in determining the final quality and performance of ceramic tiles. In modern ceramic tile production lines, roller kilns are key equipment for achieving efficient and large-scale firing of ceramic tiles.

[0003] In the process of firing the ceramic tile blanks through the roller kiln, due to the serious wear of the rollers and other reasons, it is easy to have abnormal conveying phenomena such as blank slipping and unstable conveying speed. The roller kiln in the prior art lacks a corresponding detection mechanism, and usually can only indirectly detect the conveying problem through the product quality status after the ceramic tile is fired, resulting in the inability to timely discover and solve the existing problems, which in turn affects the product quality. Therefore, we propose a roller kiln for ceramic tile production. Summary of the invention

[0009] As a further improvement of the present application, a control button for manually controlling the retracting electromagnet is also fixedly mounted on the retracting support frame, and the connection between the dummy layer and the connecting layer is a detachable fixed connection.

[0010] As a further improvement of the present application, a positioning frame matching the dummy blank measuring and transporting piece is fixedly installed on the delivery support frame, the positioning frame is set to be U-shaped, and the dummy blank measuring and transporting piece is located on the inner side of the positioning frame and movably attached to the inner wall of the positioning frame.

DETAILED DESCRIPTION

[0018] Two implementation modes of the present application are described in detail below with reference to the accompanying drawings.

[0019] The first implementation method: Figure 1-Figure 5A roller kiln for producing ceramic tiles is shown, comprising a conveying detection mechanism, a kiln body, a roller system, a combustion system, a ventilation system and a kiln control system for controlling the roller system, the combustion system and the ventilation system. The kiln body, the roller system, the combustion system, the ventilation system and the kiln control system adopt the existing technology, which is a well-known technology for those skilled in the art and will not be described in detail here. The conveying detection mechanism comprises a delivery mechanism 001 arranged at the entrance of the kiln body and a retracting mechanism 002 arranged at the exit of the kiln body. The delivery mechanism 001 comprises a delivery support frame 101, on which a vertically downwardly arranged auxiliary release cylinder 102 is fixedly mounted, and an output end of the auxiliary release cylinder 102 is fixedly connected to a controlled discharge magnet 103, and a simulated blank measuring and transporting piece 003 for simulating a ceramic tile blank is arranged at the bottom end of the controlled discharge magnet 103, and the shape, size and weight of the simulated blank measuring and transporting piece 003 are all matched with the ceramic tile blank; The retracting mechanism 002 includes a color sensor 201, a control and receiving electromagnet 202, and a feedback lamp 203. The control and receiving electromagnet 202 is located on the side of the color sensor 201 away from the kiln body outlet. The simulated blank measuring and transporting piece 003 includes a connecting layer 301 and a simulated blank layer 302 fixedly installed at the bottom of the connecting layer 301. The material of the simulated blank layer 302 matches the tile blank body. A linkage iron block 303 is embedded in the middle of the connecting layer 301 (the controlled discharge magnet 103 is in an energized state. Under the action of the magnetic attraction between the controlled discharge magnet 103 and the linkage iron block 303, the simulated blank measuring and transporting piece 003 is fixed to the bottom of the controlled discharge magnet 103). The color of the linkage iron block 303 is different from that of the connecting layer 301 and the roller system. The controlled discharge magnet 103, the color sensor 201, and the control and receiving electromagnet 202 are located on the same straight line along the conveying direction of the roller system. The conveying detection mechanism also includes an inspection and transmission intelligent control system, which includes an inspection and transmission setting module, an inspection and transmission control module, and an inspection and transmission analysis module. The inspection and transmission control module is signal-connected to the auxiliary release cylinder 102, the controlled discharge magnet 103, the color sensor 201, the controlled collection electromagnet 202, the inspection and transmission analysis module, and the roller system. The inspection and transmission setting module is signal-connected to the inspection and transmission analysis module, and the inspection and transmission analysis module is signal-connected to the feedback light 203.

[0020] According to the conveying speed of the roller system, the distance between the delivery mechanism 001 and the retracting mechanism 002 (that is, the distance between the initial position of the dummy measuring piece 003 and the color sensor 201), the recognition range of the color sensor 201 and other factors, a time interval threshold is reasonably set through the detection setting module. Before each tile firing, the conveying detection mechanism is used to detect whether there is a conveying abnormality. During the detection, the detection control module will start the roller system and control the auxiliary release cylinder 102 to drive the controlled discharge magnet 103 and the dummy measuring piece 003 to move downward a certain distance, so that the dummy measuring piece 003 is close to the roller system, and then the detection analysis module will control the controlled discharge magnet 103 to cut off the power to deliver the dummy measuring piece 003 to the On the roller system, at the same time, the detection and transport control module will also start the color sensor 201, and send a signal to the detection and transport analysis module to start timing for the detection and transport analysis module. After the simulated blank measurement and transport piece 003 is placed on the roller system, the roller system will transport the simulated blank measurement and transport piece 003 like transporting a tile blank. After the color sensor 201 is started, it will perform color recognition at a high frequency, and the color recognition data of the color sensor 201 will be transmitted to the detection and transport analysis module in real time. Since the color of the linkage iron block 303 is different from the connection layer 301, the roller system, etc., the detection and transport analysis module can accurately determine the time node when the simulated blank measurement and transport piece 003 arrives at the color sensor 201 by analyzing the recognition data of the color sensor 201; When the blank measuring piece 003 is conveyed to the color sensor 201, the detection and analysis module will stop timing, and then the detection and analysis module will determine whether there is a conveying abnormality by analyzing the timing time (that is, the time corresponding to the start timing to the end timing) and the time interval threshold. If the timing time is within the time interval threshold, it means that there is no conveying abnormality. The detection and analysis module will control the feedback light 203 to emit a green light. After the detection is completed, the tile firing can be started directly. On the contrary, if the timing time is not within the time interval threshold, it means that there is a conveying abnormality. The detection and analysis module will control the feedback light 203 to emit a red light to warn relevant personnel and prompt them to further inspect and maintain the roller system, etc.; When the inspection and transport analysis module stops timing, it will also send a signal to the inspection and transport control module, causing the inspection and transport control module to control the control and receiving electromagnet 202 to be energized, so that when the linkage iron block 303 moves to the control and receiving electromagnet 202, the simulated blank measuring and transporting piece 003 will be adsorbed to the bottom of the control and receiving electromagnet 202 under the action of the magnetic attraction between the control and receiving electromagnet 202 and the linkage iron block 303, so as to retract the simulated blank measuring and transporting piece 003, and after the detection is completed, the inspection and transport control module will control the auxiliary release cylinder 102 to drive the control and discharge magnet 103 to move upward and reset, so as to prevent the control and discharge magnet 103 from affecting the transportation of the tile blank; Therefore, by setting up the conveying detection mechanism, the conveying detection mechanism can detect the roller conveying function before firing, so as to timely discover and solve the problems of conveying abnormalities such as slipping of the green body, effectively avoid the occurrence of conveying abnormalities during the firing process of tiles, and ensure that the tile green body can stably and accurately pass through the various temperature zones of the roller kiln during the firing process, thereby effectively improving product quality.

[0021] The retracting mechanism 002 also includes a retracting support frame 204, on which a vertically downwardly arranged auxiliary retracting cylinder 205 is fixedly installed, the detection and transmission control module is connected to the auxiliary retracting cylinder 205 by signal, a support plate 206 is fixedly installed at the output end of the auxiliary retracting cylinder 205, the color sensor 201 is fixedly installed at the bottom end of the support plate 206, the feedback lamp 203 is fixedly installed on the retracting support frame 204, a boss 207 is fixedly installed at the bottom end of the support plate 206, and the control retracting electromagnet 202 is fixedly installed at the bottom end of the boss 207, and the bottom end of the control retracting electromagnet 202 is lower than the bottom end of the color sensor 201; During detection, the detection and transport control module controls the auxiliary release cylinder 102 to drive the controlled discharge magnet 103 and the simulated blank measuring and transporting piece 003 to move downward, and also controls the auxiliary collection cylinder 205 to drive the color sensor 201, the control and receiving electromagnet 202, etc. to move downward, so that the color sensor 201 and the control and receiving electromagnet 202 are close to the control button 208. On the one hand, it is beneficial for the color sensor 201 to recognize the color of the linkage iron block 303, and on the other hand, it is beneficial for the retraction of the simulated blank measuring and transporting piece 003. After the detection is completed, the detection and transport control module will also control the auxiliary collection cylinder 205 to drive the color sensor 201, the control and receiving electromagnet 202, etc. to move upward and reset to prevent the color sensor 201, etc. from affecting the transportation of the tile blank. In addition, since the bottom end of the control and receiving electromagnet 202 is lower than the bottom end of the color sensor 201, it can effectively avoid that when the simulated blank measuring and transporting piece 003 is retracted, the simulated blank measuring and transporting piece 003 hits the color sensor 201, causing the color sensor 201 to be damaged.

[0022] A control button 208 for manually controlling the control and receiving electromagnet 202 is also fixedly installed on the retracting support frame 204. After the detection is completed, the control button 208 can be used to manually cut off the power to the control and receiving electromagnet 202 to remove the simulated blank measuring and transporting piece 003 from the control and receiving electromagnet 202, so that the simulated blank measuring and transporting piece 003 can be easily put back to the control and discharge magnet 103. The connection between the simulated blank layer 302 and the connecting layer 301 is a detachable fixed connection. After a certain number of detections, the simulated blank layer 302 will inevitably be worn. In order to ensure the accuracy of subsequent detections, the simulated blank layer 302 needs to be replaced. The detachable connection between the simulated blank layer 302 and the connecting layer 301 makes it easy to replace the simulated blank layer 302, and only the simulated blank layer 302 needs to be replaced, which not only improves convenience but also reduces waste of resources.

[0023] A positioning frame 104 matching the simulated blank measuring and transporting piece 003 is fixedly installed on the delivery support frame 101. The positioning frame 104 is set to be U-shaped. The simulated blank measuring and transporting piece 003 is located on the inner side of the positioning frame 104 and is movably attached to the inner wall of the positioning frame 104. After the detection is completed, when the simulated blank measuring and transporting piece 003 is put back to the controlled discharge magnet 103, the positioning frame 104 can play a positioning role, which is conducive to the accurate placement of the simulated blank measuring and transporting piece 003, thereby ensuring the accuracy of subsequent detection.

[0024] A plurality of pairs of elastic support strips 105 are fixedly installed at the bottom end of the positioning frame 104. The elastic support strips 105 are made of elastic material and are located below the simulated blank measuring and transporting piece 003, so that during the non-detection period, the elastic support strips 105 will support the simulated blank measuring and transporting piece 003, so that the controlled discharge magnet 103 does not need to be in a powered-on state all the time. It is only necessary to power on the controlled discharge magnet 103 before starting the detection, thereby reducing energy consumption. In the detection process, since the elastic support strips 105 are elastic, when the auxiliary release cylinder 102 drives the controlled discharge magnet 103 and the simulated blank measuring and transporting piece 003 to move downward, the elastic support strips 105 can be forced to bend and deform downward to break through the obstruction of the elastic support strips 105, thereby ensuring that the detection can be carried out smoothly.

[0025] The second implementation method: Figure 6-Figure 10 A roller kiln for tile production is shown. Different from the first embodiment, a distance measuring plate 106 is provided on the positioning frame 104, and the distance measuring plate 106 is located on the side of the positioning frame 104 away from the kiln entrance. The conveying detection mechanism also includes an entry inspection and confirmation assembly, and the entry inspection and confirmation assembly includes a pair of inspection and transport plates 401, wherein the top of one inspection and transport plate 401 is fixedly connected to a magnetic suction connecting plate 402, and the top of the other inspection and transport plate 401 is fixedly connected to a vertical plate 403, and the vertical plate 403 is fixedly connected to a connecting tube 405 on one side close to the magnetic suction connecting plate 402, and the end of the connecting tube 405 connected to the vertical plate 403 is set to an open shape, and the magnetic suction connecting plate 402 is fixedly connected to a sliding support rod 404 on one side close to the vertical plate 403. The sliding support rod 404 is slidably connected to the outer wall of the connecting tube 405, and one end of the sliding support rod 404 located in the connecting tube 405 is fixedly connected to the inner distance sensor 406, and the side of the magnetic connection plate 402 away from the vertical plate 403 is fixedly connected to the outer distance sensor 407, the magnetic connection plate 402 is set to an L shape and the magnetic connection plate 402 is made of ferromagnetic material, the magnetic connection plate 402 is signal-connected to the inner distance sensor 406 and the outer distance sensor 407, and the inner distance sensor 406 and the outer distance sensor 407 are signal-connected to the vertical plate 403, and the detection and transmission intelligent control system also includes a data display module, and the detection and transmission analysis module is signal-connected to the data display module, For the convenience of description, it is assumed that the detection of whether there is a conveying abnormality by the delivery mechanism 001, the retrieving mechanism 002, the dummy blank measuring and conveying part 003, etc. in the first embodiment is a preliminary detection. In this embodiment, when the result of the preliminary detection is that there is a conveying abnormality, the detection and conveying control module will not directly control the auxiliary release cylinder 102 to drive the controlled discharge magnet 103 to move upward and reset, nor will it control the auxiliary collection cylinder 205 to drive the support plate 206, etc. to move upward and reset. After the relevant technical personnel learn that there is a conveying abnormality, that is, after seeing the feedback lamp 203 emit a red light, they will carry out further detection; Further detection: move the entry inspection and positioning assembly to the controlled discharge magnet 103, make the top of the magnetic connection plate 402 stick to the bottom of the controlled discharge magnet 103, and make the external distance sensor 407 face the distance measuring plate 106, so that the controlled discharge magnet 103 is energized, so that the entry inspection and positioning assembly is fixed at the controlled discharge magnet 103 under the action of the magnetic attraction between the controlled discharge magnet 103 and the magnetic connection plate 402, and then the inspection and transport control module will start the internal distance sensor 406 and the external distance sensor 407, and then the inspection and transport control module will control the controlled discharge magnet 103 to cut off the power, so as to put the entry inspection and positioning assembly onto the roller system, so that the roller system will transport the entry inspection and positioning assembly forward until the entry inspection and positioning assembly is transported to the retrieving mechanism 002; In the further detection process, after the inner distance sensor 406 and the outer distance sensor 407 are activated, the inner distance sensor 406 will monitor the distance between it and the vertical plate 403, and the outer distance sensor 407 will monitor the distance between it and the distance measuring plate 106, and the distance data monitored by the inner distance sensor 406 and the outer distance sensor 407 will be transmitted to the inspection and transport analysis module in real time. If there is no conveying abnormality, the two inspection and transport plates 401 will be smoothly transported forward. However, due to the existence of conveying abnormality, during the conveying process, the inspection and transport plates 401 and the magnetic connection plate 402 will move relative to each other, causing the inner distance sensor 406 and the vertical plate 403 to move relative to each other, thereby causing the inner distance sensor 406 to move relative to each other. The distance data monitored by the inner distance sensor 406 fluctuates, so that the inspection and transport analysis module can determine when the transport abnormality occurs by analyzing the distance data monitored by the inner distance sensor 406. When the distance data monitored by the inner distance sensor 406 fluctuates, the inspection and transport analysis module will record the distance data monitored by the outer distance sensor 407 at this time. Since the distance data monitored by the outer distance sensor 407 corresponds to the real-time position of the inspection and confirmation component, the distance data recorded by the inspection and transport analysis module corresponds to the position where the transport abnormality occurs. After further detection, the inspection and transport analysis module will send the recorded distance data to the data display module and make the data display module display the distance data for relevant technical personnel to view; Therefore, through the joint setting of the advance detection and positioning components, etc., the conveying detection mechanism can also perform further detection through the advance detection and positioning components when the conveying abnormality is detected to determine the location where the conveying abnormality occurs, which can be beneficial to the subsequent inspection and maintenance of the roller system, etc., and further avoid the occurrence of conveying abnormalities during the tile firing process.

[0026] After the relevant technical personnel learn that there is a conveying abnormality, before starting further inspection, they can first control the control and receiving electromagnet 202 to cut off the power through the control button 208 to remove the simulated blank measurement and transport part 003, and then control the control and receiving electromagnet 202 to be energized through the control button 208, so that when the entry inspection and positioning component moves to the control and receiving electromagnet 202, under the action of the magnetic attraction between the control and receiving electromagnet 202 and the magnetic attraction connecting plate 402, the entry inspection and positioning component will be adsorbed to the bottom end of the control and receiving electromagnet 202, so that the entry inspection and positioning component can be automatically retracted. In addition, after further inspection is completed, the inspection and transport control module will control the auxiliary release cylinder 102 to drive the control and discharge magnet 103 to move upward and reset, and control the auxiliary release cylinder 205 to drive the support plate 206 and others to move upward and reset.

[0027] An anti-slip ring 408 is sleeved on the outer wall of the sliding support rod 404 and fixedly connected thereto. The anti-slip ring 408 is located on the inner side of the connecting tube 405. The anti-slip ring 408 can prevent the sliding support rod 404 from being separated from the connecting tube 405, which is beneficial for the retraction of the inspection and positioning assembly. The ranging plate 106 is rotatably connected to the positioning frame 104 through the rotating shaft 107, so that the ranging plate 106 can be rotated. After the detection is completed, the ranging plate 106 can be rotated for adjustment to prevent the ranging plate 106 from affecting the transportation of the tile blank.

[0028] In view of current practical needs, the above-mentioned implementation mode adopted in this application is not limited to the scope of protection. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the scope of protection of the present invention.
