Description

Technical Field

[0001] This invention relates to the field of ceramic tile production, and in particular to a roller inspection device and a sintering kiln. Background Technology

[0002] The production process of ceramic tiles requires high-temperature sintering of the brick blanks to change their chemical composition and transform them into ceramic tiles. The sintering kiln is constantly exposed to high temperatures, resulting in high ambient temperatures as well. Therefore, few operators stay near the sintering kiln.

[0003] The kiln uses rollers made of alumina to transport brick blanks. However, the rollers are prone to breakage during long-term use or during the rapid cooling process after the brick blanks are sintered. Breakage not only prevents the transport of sintered brick blanks and ceramic tiles, but also causes kiln blockage. Summary of the Invention

[0049] The technical solution of the present invention will be further described below with reference to the embodiments and accompanying drawings.

[0050] Example

[0051] During the production of ceramic tiles, the tile blanks need to be sintered at high temperatures to harden and transform them into ceramic tiles. Since ceramic tiles are produced in large quantities, in order to ensure sintering efficiency, the sintering kiln uses alumina rollers to convey the tile blanks. The tile blanks pass through the sintering kiln while being conveyed by the rollers, meaning that the tile blanks are sintered inside the sintering kiln while in motion.

[0052] However, the rollers are prone to breakage during long-term use and during the rapid cooling of the brick blanks after sintering. A broken roller will warp and protrude from the conveying surface, obstructing the normal transport of the brick blanks. Since kilns require continuous heating to fire the brick blanks, the ambient temperature around the kiln is much higher than normal room temperature. Workers typically stay away from the kiln and periodically check its condition. If a roller breaks, it may not be noticed until some time has passed, during which time the brick blanks have stopped moving forward, causing a large amount of brick blanks to become stuck in the kiln.

[0053] Therefore, this application provides a roller detection device 1, referring to... Figure 1 The roller detection device 1 includes a first traction structure 10 and a second traction structure 20 arranged opposite to each other, and a rope 30 is arranged between the first traction structure 10 and the second traction structure 20.

[0054] Combination Figure 2 and Figure 3In one embodiment of the present invention, the first traction structure 10 includes a first mounting frame 11, which is used to be mounted on the side wall of the sintering kiln 6. A first trigger 12 abuts against the first mounting frame 11, and the first trigger 12 is mounted on the first mounting frame 11 by a first fastener 13. A first mounting rod 14 is provided on one side of the first mounting frame 11, which is also used to be mounted on the side wall of the kiln. The second traction structure 20 includes a second mounting frame 21 and a second mounting rod 24, which are used to be mounted on the side wall of the sintering kiln 6 and the second mounting rod 24.

[0055] Specifically, one end of the rope 30 is connected to the first mounting rod 14, and the other end of the rope 30 is connected to the second mounting rod 24. For ease of understanding, refer to... Figure 4 When the roller detection device 1 is in use, the first traction structure 10 and the second traction structure 20 are respectively set on both sides of the sintering kiln 6. Multiple rollers are arranged between the first traction structure 10 and the second traction structure 20. The rope 30 is located above the rollers, and the arrangement direction of the rope 30 and the rollers is parallel.

[0056] Combination Figure 2 and Figure 4 After the roller detection device 1 is installed, the rope 30 is positioned between the roller and the first trigger 12. (Refer to...) Figure 5 When the roller used to convey brick blanks in the sintering kiln 6 breaks, the end of the roller will tilt upwards, and the tilted end of the roller will push the rope 30 upwards.

[0057] Combination Figure 6 and Figure 7 When the rope 30 is lifted, the rope 30, which is parallel to the arrangement direction of the rollers, will tilt and the tilted rope 30 will abut against the bottom of the first trigger 12.

[0058] In one embodiment of the present invention, the first trigger 12 may be a limit switch. When the rope 30 triggers the limit switch, the limit switch can feed the signal back to the controller, and then the controller sends a signal to the alarm to make the alarm sound, thereby prompting the staff to inspect the roller.

[0059] In one embodiment of the present invention, the first mounting bracket 11 is typically made of angle steel, and one side of the angle steel can be threaded or welded to the side wall of the sintering kiln 6.

[0060] It should be noted that the rope 30 should be under appropriate tension so that the broken roller can drive the rope 30 to move upward.

[0061] Furthermore, in one embodiment of the present invention, combined with Figure 2 , Figure 5and Figure 7 The roller detection device also includes a first sensor 15, which is mounted on one end of the first mounting rod 14 and positioned above the roller. The first sensor 15 can be a laser sensor or an infrared sensor. The first sensor 15 emits a laser or infrared beam parallel to the roller's arrangement direction and positioned above the roller. When the roller breaks, if... Figure 6 The roller shown is tilted upwards at one end, at which point the broken roller will be detected by an infrared sensor or a laser sensor.

[0062] After setting the first sensor 15, the controller can combine the signals from the first sensor 15 and the first trigger 12 to make a comprehensive judgment, so as to avoid information transmission delays caused by accidental touch or failure of one of the sensors.

[0063] In one embodiment of the present invention, reference is made to... Figure 3 The second traction structure 20 also includes a second trigger 22 and a second fastener 23, the second fastener 23 being used to fix the second trigger 22 onto the second mounting bracket 21.

[0064] By configuring a second trigger 22 in conjunction with the first trigger 12, the roller bar located away from the first trigger 12 can drive the rope 30 to abut against the second trigger 22 after breakage. This avoids the situation where the rope 30 fails to trigger the first trigger 12 after being driven by the roller bar due to insufficient bending. Consequently, the roller bar detection device 1 can more accurately detect the state of the roller bar.

[0065] Of course, a second sensor 25 is correspondingly installed on the second mounting rod 24. The second sensor 25 is installed at one end of the second mounting rod 24 and is positioned above the roller.

[0066] In one embodiment of the present invention, the second sensor 25 is the same as the first sensor 15, and can be a laser sensor or an infrared sensor.

[0067] In one embodiment of the present invention, the second sensor 25 can serve as a backup sensor for the first sensor 15, so that the detection device can operate more stably.

[0068] Furthermore, the first traction structure 10 also includes a first limiting plate 16, on which a first elongated hole 161 is provided, as shown in the figure. Figure 2 The rope 30 passes through the first long hole 161, which is commonly used to limit the rope 30.

[0069] The first trigger 12 is located beside the first elongated hole 161. When the rope 30 moves upward along the first elongated hole 161, the rope 30 will not deviate during the movement, so the rope 30 can accurately trigger the first trigger 12.

[0070] In one embodiment of this invention, the first limiting plate 16 is further provided with a second elongated hole 162. The first fastener 13 passes through the second elongated hole 162 to fix the first limiting plate 16 and the first mounting bracket 11 together. The second elongated hole 162 has a certain length. Before the first fastener 13 fixes the first limiting plate 16 and the first mounting bracket 11, the first limiting plate 16 can be slightly adjusted up and down along the second elongated hole 162 so that the rope 30 abutting against the inner wall of the first elongated hole 161 can be adjusted to a suitable height, thereby facilitating the rope 30 to abut against the first trigger member 12 or the second trigger member 22.

[0071] Similarly, in one embodiment of the present invention, the second traction structure 20 further includes a second limiting plate 26, on which a third elongated hole is provided, through which the rope 30 passes, and the third elongated hole is used to limit the rope 30.

[0072] The second trigger 22 is located beside the third elongated hole. When the rope 30 moves upward along the third elongated hole, the rope 30 will not deviate during the movement, so the rope 30 can accurately trigger the second trigger 22.

[0073] In one embodiment of this invention, the second limiting plate 26 is further provided with a fourth elongated hole 261. The second fastener 23 passes through the fourth elongated hole 261 to fix the second limiting plate 26 and the second mounting bracket 21 together. The fourth elongated hole 261 has a certain length. Before the second fastener 23 fixes the second limiting plate 26 and the second mounting bracket 21, the second limiting plate 26 can be slightly adjusted up and down along the fourth elongated hole 261 so that the rope 30 abutting against the inner wall of the third elongated hole can be adjusted to a suitable height, thereby facilitating the rope 30 to abut against the first trigger 12 or the second trigger 22.

[0074] Furthermore, to enable the rope 30 to be used for extended periods in high-temperature environments, the rope 30 is typically made of metal to prevent the aging that occurs with plastic ropes such as nylon ropes at high temperatures. And to ensure accurate signal transmission when the rope 30 contacts the first trigger 12 or the second trigger 22, in one embodiment of the invention, the first trigger 12 and the second trigger 22 are made as conductors (such as readily available iron wire, aluminum wire, or copper wire). The first mounting rod 14 is insulated from the side wall of the sintering kiln 6, the second mounting rod 24 is insulated from the side wall of the sintering kiln 6, and the first trigger 12 is connected to the first mounting frame 11, and the second trigger 22 is connected to the second mounting frame 21. In this case, the first mounting frame 11, the first trigger 12, the rope 30, and the side wall of the sintering kiln 6 are all conductors, as are the second mounting frame 21 and the second trigger 22, while the first limiting plate 16 and the second limiting plate 26 are insulators. Figure 2 and Figure 3 When the metal rope is not in contact with either the first trigger 12 or the second trigger 22, no electrical path is formed between the side wall of the sintering kiln 6, the first trigger 12, and the rope 30. However, at the instant the metal rope comes into contact with either the first trigger 12 or the second trigger 22, an electrical path is formed between the metal rope and the side wall of the sintering kiln 6, at which point the controller can receive an electrical signal.

[0075] Simultaneously, in conjunction with the signals fed back by the first sensor 15 and the second sensor 25, the controller can accurately determine whether the roller is broken at this time.

[0076] In one embodiment of the present invention, the rope 30 can be made of metal wires such as long iron wire, long aluminum wire, or long copper wire.

[0077] Furthermore, referring to Figure 2 In order to ensure that the rope 30 will inevitably come into contact with the first trigger 12 during its upward movement, the first trigger 12 is set as an "L"-shaped trigger. The horizontal part of the first trigger 12 is located directly above the rope 30 and extends from one side of the first elongated hole 161 to the other side, so that it will inevitably come into contact with the first trigger 12 during its upward movement under the limitation of the first elongated hole 161.

[0078] The setting of the second trigger 22 is similar to that of the first trigger 12, and will not be described in detail here.

[0079] The present invention also discloses a sintering kiln 6, with reference to Figure 8 , Figure 9 and Figure 12The sintering kiln 6 includes the roller detection device 1 mentioned above, and the sintering kiln 6 can accurately determine whether the rollers in the sintering kiln 6 are broken, thereby reminding the staff to replace them.

[0080] A sintering kiln 6 generally includes four sintering chambers 5. In order to accurately monitor the condition of the rollers, a roller detection device 1 is installed at each sintering chamber 5. The following description will further illustrate the sintering kiln 6 using a sintering chamber 5 as an example.

[0081] Furthermore, combined Figure 8 and Figure 10 or Figure 9 and Figure 10 A pusher structure 4 is provided on the side wall of the sintering kiln 6. The pusher structure 4 is used to push the inclined rollers so that the inclined rollers can temporarily return to the horizontal position until the staff stops the conveyor belt to avoid the brick blanks from accumulating and blocking in the kiln.

[0082] Reference Figure 11 As shown by the solid line, after the roller breaks, both ends of the broken roller will tilt upwards. The pusher structure 4, located on the side wall of the sintering kiln 6, can push both ends of the roller downwards, thus allowing the roller to return to a horizontal position. Figure 11 As shown by the dashed line in the image.

[0083] Specifically, refer to Figure 10 The pusher structure 4 includes a mounting plate, which is fixedly connected to the side wall of the sintering kiln 6. A linear actuator 42 is mounted on the mounting plate, and a push plate 43 is provided on the output end of the linear actuator 42. The push plate 43 is used to abut against the roller. Figure 11 The push plate 43 is driven downward by the linear driver 42 and then abuts against both ends of the roller, causing the roller to return to a horizontal position.

[0084] In one embodiment of the present invention, the linear actuator 42 may be a cylinder, an electric cylinder, or a lead screw structure, etc., which can drive the push plate 43 to rise and fall.

[0085] Furthermore, in one embodiment of the present invention, the pusher structure 4 further includes a guide plate 44 and a second mounting plate 45. By providing the second mounting plate 45, multiple push plates 43 can be installed, thereby ensuring that a roller bar broken at any position can be pushed down.

[0086] Furthermore, combining Figure 6 and Figure 10 When a first sensor 15 and a second sensor 25 are provided, and the first sensor 15 and the second sensor 25 are laser sensors or infrared sensors, the distance between the broken roller and the first sensor 15 and the second sensor 25 can be measured.

[0087] Specific reference Figure 10 As illustrated in the figure, in one embodiment of the present invention, multiple pusher structures 4 are provided, each pusher structure 4 corresponding to push only a rated number of rollers. For example... Figure 10 Four pusher structures 4 are installed on one of the sintering chambers 5. The four pusher structures 4, from left to right, correspond to the first distance, the second distance, the third distance, and the fourth distance, respectively. The first distance, the second distance, the third distance, and the fourth distance are all within a distance range.

[0088] For example, when the sixth roller from the left breaks, the first sensor 15 measures a distance of 18cm between the first sensor 15 and the sixth roller. 18cm falls within the range of the second distance. At this time, the controller controls the second push rod structure 4 corresponding to the second distance to work, so that the roller is restored to the horizontal position more accurately.

[0089] Furthermore, while the first sensor 15 indicates that the second push rod structure 4 is working, after the push rod structure 4 is working, the push plate 43 abuts against the roller. The staff only needs to find the broken roller from the four rollers, and the maintenance staff can find the faulty roller more easily.

[0090] When two rollers break at the same time, the first sensor 15 cannot work alone. In this case, the first sensor 15, together with the second sensor 25, can control the two push rod structures 4 to work at the same time, so that the broken rollers can be temporarily restored to the horizontal position, thus avoiding blockage of the sintering kiln 6.

[0091] In one embodiment of the present invention, the push rod structure 4 is as follows: Figure 8 and Figure 9 As shown, the rollers are arranged on both sides of the sintering chamber 5, so that both ends of the broken rollers can be pressed down simultaneously.

[0092] In existing technologies, when the detection device issues an alarm after detecting a broken roller to alert personnel for repairs, the conveyor rollers at the sintering furnace are either open or closed. When the conveyor rollers are open, the broken roller will obstruct the brick blanks, causing them to accumulate and collide within the furnace, resulting in their scrap. If the conveyor rollers stop conveying after the breakage, the brick blanks being conveyed inside the furnace will remain stationary, causing a deviation in their sintering time and also rendering them unusable.

[0093] In this application, when the detection device detects a broken roller, the alarm reminds the operator to replace the roller, and the controller controls the upstream brick blanks at the sintering furnace feed inlet to stop feeding, while the brick blanks inside the sintering furnace continue to be conveyed. With the support of the push rod structure, the broken conveyor roller will continue to convey the brick blanks, so that the sintering time of the brick blanks in the sintering furnace is the same as the preset sintering time.

[0094] Prompted by the alarm, operators arrive at the sintering furnace before the brick blanks have finished sintering. Once sintering is complete, the operators shut off the conveyor rollers at the furnace and quickly locate and replace any broken rollers according to the pusher mechanism. By using the pusher mechanism and detection device in conjunction, the number of scrapped brick blanks due to roller breakage during the sintering process can be significantly reduced.

[0095] Of course, at the contact surface with the roller, the push plate 43 is equipped with balls or rollers so that the unbroken roller can rotate normally.

[0096] It is understood that those skilled in the art can make equivalent substitutions or changes to the technical solution and inventive concept of the present invention, and all such changes or substitutions should fall within the protection scope of the present invention.
