Description

Technical Field

[0001] The present invention relates to a roller hearth kiln, and particularly to a roller hearth kiln for tile production applied in the technical field of tile production. Background Art

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

[0003] During the process of firing tile blanks in a roller hearth kiln, due to severe roller wear and other reasons, abnormal conveying phenomena such as blank slippage and unstable conveying speed are likely to occur. The roller hearth kilns in the prior art lack corresponding detection mechanisms and usually can only indirectly detect conveying problems through the product quality status after tile firing is completed, resulting in the inability to timely discover and solve existing problems, which will in turn affect product quality. Therefore, we propose a roller hearth kiln for tile production. Summary of the Invention

[0004] Aiming at the above-mentioned prior art, the technical problem to be solved by the present invention is: how to avoid abnormal conveying phenomena such as blank slippage and unstable conveying speed when firing tile blanks in a roller hearth kiln.

[0005] To solve the above problems, the present invention provides a roller hearth kiln for tile production, including 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 conveying detection mechanism includes a feeding mechanism arranged at the entrance of the kiln body and a retrieving mechanism arranged at the exit of the kiln body. The feeding mechanism includes a feeding support frame, on which a vertically downwardly arranged assisting cylinder is fixedly installed. The output end of the assisting cylinder is fixedly connected with a control electromagnet for releasing. At the bottom end of the control electromagnet for releasing, a simulated blank measuring and conveying part for simulating a tile blank is arranged. The shape, size, and weight of the simulated blank measuring and conveying part are all matched with those of the tile blank.

[0006] The retrieving mechanism includes a color sensor, a control electromagnet for retrieving, and a feedback lamp. The control electromagnet for retrieving is located on the side of the color sensor away from the exit of the kiln body. The simulated blank measuring and conveying part includes a connecting layer and a simulated blank layer fixedly installed at the bottom end of the connecting layer. The material of the simulated blank layer is matched with that of the tile blank. A linkage iron block is embedded in the middle of the connecting layer. The color of the linkage iron block is different from the colors of both the connecting layer and the roller system. The control electromagnet for releasing, the color sensor, and the control electromagnet for retrieving are located on the same straight line along the conveying direction of the roller system.

[0007] In the above roller hearth kiln for tile production, the conveying detection mechanism can detect the roller conveying function before firing, so as to timely discover and solve problems such as abnormal conveying that may cause the green body to slip, effectively avoiding abnormal conveying phenomena during tile firing.

[0008] As a further improvement of the present application, the conveying detection mechanism further includes a conveying detection intelligent control system. The conveying detection intelligent control system includes a conveying detection setting module, a conveying detection control module, and a conveying detection analysis module.

The conveying detection setting module is signal-connected to the conveying detection analysis module, and the conveying detection analysis module is signal-connected to the feedback lamp.

[0009] As a further improvement of the present application, the retracting mechanism further includes a retracting support frame. A vertically downwardly arranged assisting retracting cylinder is fixedly installed on the retracting support frame. The conveying detection control module is signal-connected to the assisting retracting cylinder. The output end of the assisting retracting cylinder is fixedly installed with a support plate. The color sensor is fixedly installed at the bottom end of the support plate. The feedback lamp is fixedly installed on the retracting support frame. A boss is fixedly installed at the bottom end of the support plate. The control receiving electromagnet is fixedly installed at the bottom end of the boss, and the bottom end of the control receiving electromagnet is lower than the bottom end of the color sensor.

[0010] As a further improvement of the present application, a control button for manually controlling the control receiving electromagnet is also fixedly installed on the retracting support frame. The connection between the simulated blank layer and the connection layer is a detachable fixed connection.

[0011] As a further improvement of the present application, a positioning frame matching the simulated blank measuring and conveying member is fixedly installed on the placing support frame. The positioning frame is arranged in a U shape. The simulated blank measuring and conveying member is located inside the positioning frame and is movably attached to the inner wall of the positioning frame.

[0012] As a further improvement of the present application, multiple pairs of elastic support strips are fixedly installed at the bottom end of the positioning frame. The elastic support strips are made of elastic materials and are located below the simulated blank measuring and conveying member.

[0013] As another improvement of the present application, a ranging board is provided on the positioning frame.

Specific embodiments

[0029] The following describes the two embodiments of the present application in detail with reference to the accompanying drawings.

[0030] The first embodiment:

[0031] Figures 1 - 5 There is shown a roller hearth kiln for tile production, including a conveying and detecting mechanism, a kiln body, a roller hearth system, a combustion system, a ventilation system, and a kiln control system for controlling the roller hearth system, the combustion system, and the ventilation system. The kiln body, the roller hearth system, the combustion system, the ventilation system, and the kiln control system adopt existing technologies, which are well-known technologies in the art and will not be elaborated here. The conveying and detecting mechanism includes a feeding mechanism 001 arranged at the entrance of the kiln body and a retrieving mechanism 002 arranged at the exit of the kiln body. The feeding mechanism 001 includes a feeding support frame 101, on which a releasing cylinder 102 arranged vertically downward is fixedly installed. The output end of the releasing cylinder 102 is fixedly connected with a control releasing electromagnet 103. At the bottom end of the control releasing electromagnet 103, there is a simulated blank detecting and conveying member 003 for simulating a tile blank. The shape, size, and weight of the simulated blank detecting and conveying member 003 are all matched with those of the tile blank.

[0032] The retrieving mechanism 002 includes a color sensor 201, a control retrieving electromagnet 202, and a feedback lamp 203. The control retrieving electromagnet 202 is located on the side of the color sensor 201 away from the exit of the kiln body. The simulated blank detecting and conveying member 003 includes a connecting layer 301 and a simulated blank layer 302 fixedly installed at the bottom end of the connecting layer 301. The material of the simulated blank layer 302 is matched with that of the tile blank. A linkage iron block 303 is embedded in the middle of the connecting layer 301 (when the control releasing electromagnet 103 is in the energized state, under the action of the magnetic attraction force between the control releasing electromagnet 103 and the linkage iron block 303, the simulated blank detecting and conveying member 003 is fixed at the bottom end of the control releasing electromagnet 103). The color of the linkage iron block 303 is different from the colors of both the connecting layer 301 and the roller hearth system. The control releasing electromagnet 103, the color sensor 201, and the control retrieving electromagnet 202 are located on the same straight line along the conveying direction of the roller hearth system.

[0033] The conveying and detecting mechanism further includes a detecting and conveying intelligent control system, which includes a detecting and conveying setting module, a detecting and conveying control module, and a detecting and conveying analysis module. The detecting and conveying control module is in signal connection with the releasing cylinder 102, the control releasing electromagnet 103, the color sensor 201, the control retrieving electromagnet 202, the detecting and conveying analysis module, and the roller hearth system. The detecting and conveying setting module is in signal connection with the detecting and conveying analysis module. The detecting and conveying analysis module is in signal connection with the feedback lamp 203.

[0034] According to factors such as the conveying speed of the roller table system, the distance between the placing mechanism 001 and the retracting mechanism 002 (i.e., the distance between the initial position of the pseudo blank measuring and conveying part 003 and the color sensor 201), and the recognition range of the color sensor 201, a duration interval threshold is reasonably set through the inspection and conveying setting module. Before each tile firing, first, the conveying detection mechanism is used to detect whether there is abnormal conveying. During the detection, the inspection and conveying control module will start the roller table system and control the assisting placing cylinder 102 to drive the control placing electromagnet 103 and the pseudo blank measuring and conveying part 003 to move downward by a certain distance, so that the pseudo blank measuring and conveying part 003 approaches the roller table system. Then, the inspection and conveying analysis module will control the control placing electromagnet 103 to power off to place the pseudo blank measuring and conveying part 003 onto the roller table system. At the same time, the inspection and conveying control module will also start the color sensor 201 and send a signal to the inspection and conveying analysis module to start timing. After the pseudo blank measuring and conveying part 003 is placed onto the roller table system, the roller table system will convey the pseudo blank measuring and conveying part 003 like conveying 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 inspection and conveying analysis module in real time. Since the color of the linkage iron block 303 is different from that of the connection layer 301, the roller table system, etc., the inspection and conveying analysis module can accurately judge the time node when the pseudo blank measuring and conveying part 003 reaches the color sensor 201 by analyzing the recognition data of the color sensor 201;

[0035] When the pseudo blank measuring and conveying part 003 is conveyed to the color sensor 201, the inspection and conveying analysis module will stop timing. Then, the inspection and conveying analysis module will judge whether there is abnormal conveying by analyzing the timing duration (i.e., the duration corresponding to the start of timing to the end of timing) and the duration interval threshold. If the timing duration is within the duration interval threshold, it means there is no abnormal conveying. The inspection and conveying analysis module will control the feedback lamp 203 to emit green light. After the detection is completed, the tile firing can be directly started. On the contrary, if the timing duration is not within the duration interval threshold, it means there is abnormal conveying. The inspection and conveying analysis module will control the feedback lamp 203 to emit red light to warn relevant personnel, prompting relevant personnel to further check and maintain the roller table system, etc.;

[0036] At the same time as the inspection and conveying analysis module stops timing, it will also send a signal to the inspection and conveying control module, causing the inspection and conveying control module to control the control retracting electromagnet 202 to be energized. When the linkage iron block 303 moves to the control retracting electromagnet 202, the pseudo blank measuring and conveying part 003 will be adsorbed to the bottom of the control retracting electromagnet 202 under the action of the magnetic attraction between the control retracting electromagnet 202 and the linkage iron block 303 to retract the pseudo blank measuring and conveying part 003. After the detection is completed, the inspection and conveying control module will control the assisting placing cylinder 102 to drive the control placing electromagnet 103 to move upward to reset, preventing the control placing electromagnet 103 from affecting the conveying of the tile blank;

[0037] Therefore, through the setting of the conveying and detecting mechanism, the conveying and detecting mechanism can detect the roller conveying function before firing, so as to timely discover and solve problems such as abnormal conveying that may cause the blank to slip, effectively avoid the phenomenon of abnormal conveying during the firing of the ceramic tile, ensure that the ceramic tile blank can stably and accurately pass through each temperature zone of the roller kiln during the firing process, and thus effectively improve the product quality.

[0038] The retracting mechanism 002 further includes a retracting support frame 204. A retracting air cylinder 205 vertically downward is fixedly installed on the retracting support frame 204. The inspection and conveying control module is in signal connection with the retracting air cylinder 205. The output end of the retracting air cylinder 205 is fixedly installed with a support plate 206. 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. 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.

[0039] During detection, when the inspection and conveying control module controls the assisting placing air cylinder 102 to drive the control placing electromagnet 103 and the simulated blank inspection and conveying part 003 to move downward, it will also control the retracting air cylinder 205 to drive the color sensor 201, the control retracting electromagnet 202, etc. to move downward, so that the color sensor 201 and the control retracting electromagnet 202 are close to the control button 208. On the one hand, it is beneficial for the color sensor 201 to identify the color of the linkage iron block 303. On the other hand, it is beneficial for the retraction of the simulated blank inspection and conveying part 003. After the detection is completed, the inspection and conveying control module will also control the retracting air cylinder 205 to drive the color sensor 201, the control retracting electromagnet 202, etc. to move upward to reset, preventing the color sensor 201, etc. from affecting the conveying of the ceramic tile blank. In addition, since the bottom end of the control retracting electromagnet 202 is lower than the bottom end of the color sensor 201, it can effectively avoid the simulated blank inspection and conveying part 003 hitting the color sensor 201 and damaging the color sensor 201 when the simulated blank inspection and conveying part 003 is retracted.

[0040] A control button 208 for manually controlling the control retracting electromagnet 202 is also fixedly installed on the retracting support frame 204. After the detection is completed, the control retracting electromagnet 202 can be manually powered off through the control button 208 to remove the simulated blank inspection and conveying part 003 from the control retracting electromagnet 202, so that the simulated blank inspection and conveying part 003 is convenient to be placed back at the control placing electromagnet 103. The connection between the simulated blank layer 302 and the connection layer 301 is a detachable fixed connection. After a certain number of detections, the simulated blank layer 302 will inevitably be worn. 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 connection layer 301 makes the simulated blank layer 302 convenient to replace, and only the simulated blank layer 302 needs to be replaced, which not only improves the convenience but also reduces the waste of resources.

[0041] A positioning frame 104 that matches the quasi-blank detection and conveying part 003 is fixedly installed on the placement support frame 101. The positioning frame 104 is set in a U shape. The quasi-blank detection and conveying part 003 is located inside the positioning frame 104 and is in movable contact with the inner wall of the positioning frame 104. After the detection is completed, when the quasi-blank detection and conveying part 003 is placed back at the control release electromagnet 103, the positioning frame 104 can play a positioning role, which is beneficial to the accurate placement of the quasi-blank detection and conveying part 003, and thus ensures the accuracy of subsequent detection.

[0042] A plurality of pairs of elastic support strips 105 are fixedly installed at the bottom ends of the positioning frame 104. The elastic support strips 105 are made of elastic materials, and the elastic support strips 105 are located below the quasi-blank detection and conveying part 003. During non-detection periods, the elastic support strips 105 will support the quasi-blank detection and conveying part 003, so that the control release electromagnet 103 does not need to be continuously powered on. It only needs to be powered on before the start of detection, which can reduce energy consumption. During the detection process, due to the elasticity of the elastic support strips 105, when the assisting cylinder 102 drives the control release electromagnet 103 and the quasi-blank detection and conveying part 003 to move downward, it can break through the obstruction of the elastic support strips 105 by forcing the elastic support strips 105 to bend downward and deform, thus ensuring the smooth progress of the detection.

[0043] The second implementation mode:

[0044] Figures 6 - 10There is shown a roller hearth kiln for tile production. Different from the first embodiment, a ranging plate 106 is provided on the positioning frame 104. The ranging plate 106 is located on the side of the positioning frame 104 away from the kiln body entrance. The conveying detection mechanism further includes an inlet detection and positioning assembly. The inlet detection and positioning assembly includes a pair of detection and conveying plates 401. At the top of one of the detection and conveying plates 401, a magnetic adsorption connecting plate 402 is fixedly connected. At the top of the other detection and conveying plate 401, a vertical plate 403 is fixedly connected. On the side of the vertical plate 403 close to the magnetic adsorption connecting plate 402, a connecting cylinder 405 is fixedly connected. One end of the connecting cylinder 405 connected to the vertical plate 403 is arranged in an open shape. On the side of the magnetic adsorption connecting plate 402 close to the vertical plate 403, a sliding connection support rod 404 is fixedly connected. The sliding connection support rod 404 penetrates through the outer wall of the connecting cylinder 405 and extends to the inside of the connecting cylinder 405, and the sliding connection support rod 404 is slidably connected to the outer wall of the connecting cylinder 405. At one end of the sliding connection support rod 404 located inside the connecting cylinder 405, an internal distance sensor 406 is fixedly connected. On the side of the magnetic adsorption connecting plate 402 away from the vertical plate 403, an external distance sensor 407 is fixedly connected. The magnetic adsorption connecting plate 402 is arranged in an L shape and is made of ferromagnetic material. The magnetic adsorption connecting plate 402 is signal-connected to both the internal distance sensor 406 and the external distance sensor 407. Both the internal distance sensor 406 and the external distance sensor 407 are signal-connected to the vertical plate 403. The conveying detection intelligent control system further includes a data display module. The conveying detection analysis module is signal-connected to the data display module.

[0045] For the convenience of description, let the detection of whether there is abnormal conveying through the feeding mechanism 001, the retracting mechanism 002, the pseudo blank detecting and conveying member 003, etc. in the first embodiment be the preliminary detection. In this embodiment, when the result of the preliminary detection is that there is abnormal conveying, the conveying detection control module will not directly control the assisting release cylinder 102 to drive the control release electromagnet 103 to move upward for reset, nor will it control the assisting retracting cylinder 205 to drive the support plate 206, etc. to move upward for reset. After the relevant technical personnel learn that there is abnormal conveying, that is, after seeing the feedback lamp 203 emit red light, they will carry out further detection.

[0046] Further detection: Move the inlet detection and positioning assembly to the control release electromagnet 103, make the top of the magnetic adsorption connecting plate 402 abut against the bottom of the control release electromagnet 103, and make the external distance sensor 407 face the ranging plate 106. Energize the control release electromagnet 103 so that under the action of the magnetic attraction force between the control release electromagnet 103 and the magnetic adsorption connecting plate 402, the inlet detection and positioning assembly is fixed at the control release electromagnet 103. Then the conveying detection control module will start the internal distance sensor 406 and the external distance sensor 407. Subsequently, the conveying detection control module will control the control release electromagnet 103 to be de-energized to place the inlet detection and positioning assembly on the roller system, causing the roller system to convey the inlet detection and positioning assembly forward until the inlet detection and positioning assembly is conveyed to the retracting mechanism 002.

[0047] During 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 ranging plate 106. Moreover, the distance data monitored by the inner distance sensor 406 and the outer distance sensor 407 will be transmitted to the inspection and transmission analysis module in real time. If there is no abnormal transmission, the two inspection and transmission plates 401 will be smoothly conveyed forward. However, due to the abnormal transmission, during the conveying process, relative movement will occur between the inspection and transmission plate 401 and the magnetic attraction connection plate 402, resulting in relative movement between the inner distance sensor 406 and the vertical plate 403. As a result, the distance data monitored by the inner distance sensor 406 will fluctuate, enabling the inspection and transmission analysis module to determine when the abnormal transmission 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 transmission 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 incoming inspection and positioning component, the distance data recorded by the inspection and transmission analysis module corresponds to the position where the abnormal transmission occurs. After the further detection is completed, the inspection and transmission analysis module will send the recorded distance data to the data display module and enable the data display module to display the distance data for relevant technical personnel to view;

[0048] Therefore, through the combined setting of the incoming inspection and positioning component and others, the conveying detection mechanism can also conduct further detection through the incoming inspection and positioning component and others when detecting abnormal transmission to determine the position where the abnormal transmission occurs, which is beneficial to subsequent inspection and maintenance of the roller table system and others, and further avoids the phenomenon of abnormal transmission during the tile firing process.

[0049] After relevant technical personnel learn that there is abnormal transmission, before starting the further detection, they can first control the control receiving electromagnet 202 to power off through the control button 208 to remove the quasi - blank inspection and transmission part 003, and then control the control receiving electromagnet 202 to power on through the control button 208. When the incoming inspection and positioning component moves to the position of the control receiving electromagnet 202, under the action of the magnetic attraction force between the control receiving electromagnet 202 and the magnetic attraction connection plate 402, the incoming inspection and positioning component will be adsorbed to the bottom end of the control receiving electromagnet 202, thus automatically retracting the incoming inspection and positioning component. In addition, after the further detection is completed, the inspection and transmission control module will control the assisting release cylinder 102 to drive the control release electromagnet 103 to move upward for reset, and control the assisting receiving cylinder 205 to drive the support plate 206 and others to move upward for reset.

[0050] A anti - detachment snap ring 408 fixedly connected therewith is sleeved on the outer wall of the sliding connection support rod 404. The anti - detachment snap ring 408 is located inside the connection cylinder 405. The anti - detachment snap ring 408 can prevent the sliding connection support rod 404 from detaching from the connection cylinder 405, which is beneficial to the retraction of the inspection - access positioning assembly. The distance - measuring plate 106 is rotatably connected to the positioning frame 104 through a rotating shaft 107, enabling the distance - measuring plate 106 to rotate. After the detection, the distance - measuring plate 106 can be rotated for adjustment to prevent the distance - measuring plate 106 from affecting the conveying of the ceramic tile blank.

[0051] Combined with the current actual requirements, the above - mentioned implementation manner adopted in this application, the scope of protection is not limited thereto. Within the scope of knowledge possessed by those skilled in the art, various changes made without departing from the concept of this application still fall within the protection scope of the present invention.
