Description

Technical Field

[0001] This invention relates to the field of ceramic tile production technology, and in particular to a grinding production line for double-sided ceramic tiles and its control method. Background Technology

[0002] In the production process of ceramic tiles, the pressed shape of the tile blank is generally a regular cuboid. In actual decoration, such as at the corner of the wall, the tiles need to be chamfered. Therefore, tile production lines usually have an edge grinding mechanism. However, existing edge grinding production lines can usually only grind the edge of one tile at a time, resulting in low production efficiency. Moreover, their edge grinding mechanism can usually only grind one side of the tile's side, either the top edge or the bottom edge, and cannot grind both the top and bottom edges of the tile's side simultaneously, leading to low grinding efficiency and poor grinding consistency.

[0003] Furthermore, in ceramic tile production lines, lifting roller tables are typically used as transfer hubs. The lower frame is raised and lowered as a whole by a lifting motor with a single output shaft. This means that the roller table is raised and lowered by a single output shaft, resulting in a large output load on the output shaft of the lifting motor, a high failure rate, and a short service life. Summary of the Invention

[0004] The purpose of this invention is to propose a double-sided ceramic tile edge grinding production line and its control method, which solves the problems of existing edge grinding production lines, which can usually only grind one ceramic tile at a time, and whose edge grinding mechanisms can usually only grind one side of the ceramic tile's side edge, either the top or the bottom edge, and cannot grind both sides of the ceramic tile's side edge simultaneously.

Compared with the single-axis output method, the dual-axis drive motor can realize dual-axis output, which can not only reduce the load on the output shaft of the dual-axis drive device, but also improve its service life and reduce the failure rate, thus improving the production efficiency and service life of the edge grinding production line.

[0049] 2. The grinding component, consisting of a first fixed frame, a first movable seat, a first driving device, a fixed seat, a second movable seat, a second driving device, a grinding component, and a third driving device, can move up and down and left and right, thus enabling the grinding of tiles of different sizes.

Detailed Implementation

[0054] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0055] In one embodiment of the present invention, such as Figure 1-15As shown, a double-sided ceramic tile edge grinding production line includes a first edge grinding mechanism 1, a centering mechanism 2, a first conveying mechanism 3, a second conveying mechanism 4, a conveyor belt 5, a sixth drive device (not shown), a second edge grinding mechanism 6, and a third conveying mechanism 7. The first edge grinding mechanism 1 and the centering mechanism 2 are respectively installed on the first conveying mechanism 3. The centering mechanism 2 is located in front of the first edge grinding mechanism 1. The input end of the first conveying mechanism 3 is perpendicular to the output end of the second conveying mechanism 4. The output end of the third conveying mechanism is directly connected to the input end of the second conveying mechanism. The second edge grinding mechanism 6 is installed on the third conveying mechanism. 7; The second conveying mechanism 4 includes a base frame 411, a roller table 42, and a dual-axis drive device 49. The roller table 42 is vertically and flexibly mounted on the base frame 411. The dual-axis drive device 49 drives the roller table 42 to move up and down. The conveyor belt 5 is provided between two adjacent conveying rollers of the roller table 42. The conveyor belt 5 is directly opposite the first conveying mechanism 3. The sixth drive device drives multiple conveyor belts 5 to rotate. The roller table 42 has a first conveying area 421 and a second conveying area 422. The first conveying area 421 is located to the left of the second conveying area 422. The conveying speed of the first conveying area 421 is lower than that of the second conveying area 422. The conveying speed of the conveying zone 422; the first grinding mechanism 1 includes a first fixed frame 11, a first movable seat 12, a first driving device 13, a fixed seat 14, a second movable seat 15, a second driving device 16, a grinding piece 17, and a third driving device 18; the first movable seat 12 is movably mounted on the first fixed frame 11, and the number of the first movable seats 12 is four. Two first movable seats 12 are respectively installed at the left and right ends of the front side of the first fixed frame 11, and two first movable seats 12 are respectively installed in the middle of the rear side of the first fixed frame 11. The first driving device 13 is used to drive the first movable seats 12 to move left and right. The fixed base 14 is mounted on the first movable base 12, and the second movable base 15 is movably mounted on the fixed base 14. The second driving device 16 is used to drive the second movable base 15 to move up and down. The grinding component 17 is rotatably mounted on the second movable base 15, and the third driving device 18 is used to drive the grinding component 17 to rotate. The grinding component 17 includes a first platform 171 and a second platform 172. The diameter of the top of the first platform 171 is larger than the diameter of its bottom. The bottom of the first platform 171 is connected to the top of the second platform 172, and the first platform 171 and the second platform 172 are mirror symmetrical. In this embodiment, the dual-axis driving device 49 is a dual-axis motor. The first conveying mechanism 3, the roller table 42, the third conveying mechanism 7, and the second edge grinding mechanism 6 are existing technologies. Preferably, the third conveying mechanism 7 has a uniform speed zone and a deceleration zone, with the deceleration zone located to the left of the uniform speed zone, thereby facilitating the second tile to catch up with the first tile.The second edge grinding mechanism 6 is used to grind the two short edges of a single tile. It should be noted that the previous process already includes a centering step, therefore the second edge grinding mechanism 6 does not need to be centered. The first edge grinding mechanism 1 is used to grind the two long edges of two tiles. The sixth driving device is a motor. Multiple conveyor belts 5 are fixedly installed on the base frame 411. The first platform 171 and the second platform 172 have the same structure and are mirror-symmetrical. The cross-sections of the first platform 171 and the second platform 172 are both trapezoidal. The first fixed frame 11 is installed on the first conveying mechanism 3. Specifically, the first moving seat 12, the first driving device 13, the fixed seat 14, the second moving seat 15, the second driving device 16, the grinding piece 17, and... The number of third drive devices 18 is four. The two grinding pieces 17 at the left and right ends of the front side of the first fixed frame 11 grind the top and bottom edges of the outer surfaces of two tiles, respectively. The two grinding pieces 17 in the middle of the rear side of the first fixed frame 11 grind the top and bottom edges of the inner surfaces of two tiles, respectively. During operation, after the second edge grinding mechanism 6 finishes grinding the two short edges of a single tile, the tile enters the second conveying mechanism 4 after passing through the speed change of the third conveying mechanism 7. The second conveying mechanism 4 conveys the tile from right to left, that is, the roller table 42 conveys the tile from right to left. When the tile enters the first conveying area 421, the rotation speed of the conveying rollers in the first conveying area 421 decreases, thereby reducing the conveying speed of the tile. Meanwhile, the second conveying area 422... The conveying speed remains constant, allowing the second tile to quickly catch up with the first tile. Once both tiles are conveyed to the set position by the roller table 2, the top surfaces of the multiple conveyor belts 5 are lower than the top surfaces of the conveyor rollers of the roller table 42. Then, the dual-shaft drive device 49 drives the roller table 42 to descend, and the two tiles follow, falling onto the top surfaces of the multiple conveyor belts 5. The sixth drive device then drives the multiple conveyor belts 5 to rotate, thus conveying the two tiles from the second conveying mechanism 4 to the first conveying mechanism 3. The first conveying mechanism 3 then conveys the tiles to the centering mechanism 2, which centers and positions the two tiles, providing a basis for the subsequent precise grinding by the first edge-grinding mechanism 1. After centering, the first conveyor... Mechanism 3 conveys the tile to the first edge-grinding mechanism 1 for grinding. Specifically, the first driving device 13 drives the first moving seat 12 to move left and right along the length of the first fixed frame 11, thereby adjusting the position of the grinding piece 17 in the left and right directions. Then, the second driving device 5 drives the second moving seat 15 to move up and down, thereby adjusting the height of the grinding piece 17. The third driving device 18 drives the grinding piece 17 to rotate. When the first conveying mechanism 3 conveys the tile to the grinding piece 17, the first platform 171 and the second platform 172 simultaneously grind the top and bottom edges of the tile side by rotating, thereby removing burrs from the top and bottom edges of the tile side.Furthermore, this application utilizes a base frame 411, roller table 42, first conveyor area 421, second conveyor area 422, conveyor belt 5, sixth drive device, and dual-axis drive device 49 to enable the second tile to quickly catch up with the first tile and transfer the two tiles at the corner, which is convenient and fast. Compared with the single-axis output method, the use of a dual-axis drive motor to achieve dual-axis output not only reduces the load on the output shaft of the dual-axis drive device 49, but also increases its service life and reduces the failure rate, thereby improving the production efficiency and service life of the edge grinding production line. Moreover, through the first fixed frame 11, first movable seat 12, first drive device 13, fixed seat 14, second movable seat 15, second drive device 16, grinding component 17, and third drive device 18, the grinding component 17 can move up and down and left and right, thus enabling the grinding of tiles of different sizes. This system boasts high versatility and employs a rotating mechanism to simultaneously grind the top and bottom edges of the tile sides using the first platform 171 and the second platform 172. This achieves the purpose of removing burrs and chamfering, offering convenience and speed. Furthermore, the synchronous rotation of the first platform 171 and the second platform 172 ensures consistent grinding quality on the top and bottom edges of the tile sides, thereby improving the production quality and efficiency of the edge grinding production line. Specifically, the system comprises four components: the first moving seat 12, the first driving device 13, the fixed seat 14, the second moving seat 15, the second driving device 16, the grinding components 17, and the third driving device 18. The two grinding components 17 at the left and right ends of the front side of the first fixed frame 11 grind the top and bottom edges of the outer sides of two tiles, while the two grinding components 17 in the middle of the rear side of the first fixed frame 11 grind the top and bottom edges of the inner sides of two tiles, achieving simultaneous grinding of two tiles and further improving the production efficiency of the edge grinding production line.

During operation, the first conveying mechanism 3 conveys the tile through the grinding port 1931 of the dust collection hood 193. The first platform 171 and the second platform 172 inside the grinding port 1931 grind the top and bottom edges of the tile side. The dust generated during grinding falls inside the dust collection hood 193 and is sucked away by the seventh driving device through the suction pipe, preventing the dust from scattering. In this embodiment, the third driving device 18 is a motor. During installation, the mounting plate 191 and the third driving device 18 are respectively installed on the second movable base 15, and the third driving device 18 is located in the mounting groove 1911, thereby making the structure of the first edge grinding mechanism 1 more compact, which is beneficial to improving the structural stability and space utilization of the first edge grinding mechanism 1. In this embodiment, the two mounting platforms 173, the first platform body 171 and the second platform body 172 are an integral structure. The mounting platform 173 is provided with threaded holes. The output end of the third driving device 18 is connected to the mounting platform 173 through the threaded holes, thereby making it convenient to disassemble and assemble the grinding part 17 and improving the efficiency of disassembly and assembly of the grinding part 17.In this embodiment, the baffle 110 is provided on the front side of the fixed seat 14, thereby reducing the probability of dust adhering to the second lead screw 142 and the second slide rail 141 inside the fixed seat 14. The baffle 110 not only serves as a guide, allowing the second movable seat 15 to move up and down along the length direction of the baffle 110, but also enhances the connection stability between the fixed seat 14 and the second movable seat 15.

[0058] like Figure 5-6As shown, the centering mechanism 2 includes a second fixed frame 21, a fourth driving device 22, a third movable seat 23, a fourth movable seat 24, a fifth driving device 25, a push plate 26, push wheels 27, and photoelectric sensors (not shown in the figure); the third movable seat 23 and the fourth movable seat 24 are respectively movably mounted on the second fixed frame 21. The push plate 26 is mounted on the bottom of the third movable seat 23. Multiple push wheels 27 are mounted on the bottom surface of the push plate 26. The multiple push wheels 27 are evenly arranged along the length direction of the push plate 26.The fifth driving device 25 is used to drive the fourth movable seat 24 to move left and right. The fourth driving device 22 is installed on the fourth movable seat 24 and is used to drive the third movable seat 23 to move left and right. The photoelectric sensor is electrically connected to the fourth driving device 22 and is used to sense whether a tile has passed by. In this embodiment, the fourth driving device 22 is an electric cylinder. The fourth driving device 22 is electrically connected to the control system. The control system can control the stroke of the fourth driving device 22 by input parameters, making the movement stroke of the fourth driving device 22 more precise, providing a basis for the precise grinding of the subsequent first edge grinding mechanism 1. The second fixing frame 21 is installed on the first conveying mechanism 3. The photoelectric sensor is a commercially available sensor and is electrically connected to the conveying roller of the first conveying mechanism 3. The number of the fourth driving device 22, the third movable seat 23, the fourth movable seat 24, the fifth driving device 25, the push plate 26, the push wheel 27, and the photoelectric sensor are respectively... Secondly, during operation, when the first conveying mechanism 3 conveys two tiles past the corresponding two photoelectric sensors, the photoelectric sensors start working and feed back electrical signals to the first conveying mechanism 3, thereby stopping the conveying rollers of the first conveying mechanism 3. At this time, the two tiles stop below the second fixed frame 21 and are directly opposite the push plate 26. Simultaneously, the fourth driving device 22 receives the signal from the photoelectric sensors and starts working. Specifically, according to the stroke setting of the control system, the output end of the fourth driving device 22 extends and pushes the third moving seat 23 to move, thereby causing the multiple push rollers 27 on the bottom surface of the push plate 26 to place the two tiles... Once pushed to the set position, multiple push rollers 27 are evenly arranged along the length of the push plate 26, ensuring that the tile moves in a straight line during pushing, avoiding deviation during the pushing process, and improving the stability and reliability of the pushing. After being pushed to the set position, the first conveying mechanism 3 conveys the tile to the first edge grinding mechanism 1, which grinds the top and bottom edges of the tile. Furthermore, the position of the third moving seat 23 can be adjusted by the fifth driving device 25. Specifically, the fifth driving device 25 drives the fourth moving seat 24 to move left and right, and the fourth moving seat 24 drives the third moving seat 23. The fourth drive device 22 moves left and right. At this time, it is not necessary to adjust the travel of the fourth drive device 22 to achieve the purpose of centering and positioning tiles of different sizes, which is convenient for changing the model of the product during production. In this embodiment, through the second fixed frame 21, the fourth drive device 22, the third moving seat 23, the push plate 26, the push roller 27, the photoelectric eye and the first edge grinding mechanism 1, the multiple push rollers 27 push the tiles to the set position in a straight state, which is convenient and fast, and ensures the stability and reliability of the push. This provides a foundation for the subsequent precise grinding of the first edge grinding mechanism 1, thereby improving the grinding quality of the first edge grinding mechanism 1.Furthermore, through the fourth movable seat 24 and the fifth driving device 25, the centering and positioning of tiles of different sizes can be achieved without adjusting the travel of the fourth driving device 22. This not only provides high adjustment efficiency but also makes it suitable for centering different types of tiles, thereby improving the versatility and adjustment efficiency of the centering mechanism 1.

In this embodiment, the fifth driving device 25 is a handwheel. Using a handwheel as a driving component makes it easy for employees to make fine adjustments. During operation, rotating the fifth driving device 25 causes the third lead screw 211 to rotate. The third lead screw 211 causes the fourth moving seat 24 to move left and right through the third connecting block 241. The limiting nut 212 is provided at the end of the third lead screw 211 to prevent the third connecting block 241 from coming out of the third lead screw 211, thereby ensuring the working stability of the edge grinding machine. In this embodiment, the third slider 231 and the fourth slider 242 are respectively provided on the top of the third movable seat 23 and the top of the fourth movable seat 24, so that the third slider 231 and the fourth slider 242 are slidably mounted on the third slide rail 213 of the second fixed frame 21, thereby improving the smoothness of movement of the third movable seat 23 and the fourth movable seat 24. Furthermore, the stop block 214 is provided at the end of the third slide rail 213 to prevent the third slider 231 and the fourth slider 242 from sliding out of the third slide rail 213, thereby ensuring the working stability of the edge grinding machine. In this embodiment, in order to ensure the smooth movement of the third connecting block 241 on the third lead screw 211, lubricating oil is usually applied to the surface of the third lead screw 211. Therefore, the cover 28 is provided. The cover 28 acts as a barrier, which can reduce the amount of dust adhering to the surface of the third lead screw 211. Furthermore, the cover 28 can slide left and right along the length direction of the slide groove 215, thereby adjusting the position of the cover 28, which makes it convenient for employees to stand on the top of the cover 28 to adjust or maintain the centering mechanism 2.

[0060] like Figure 8-9As shown, the second conveying mechanism 4 further includes a drive rod 43, an eccentric rotation assembly 44, a first connecting rod 451, a second connecting rod 452, a first connecting assembly 461, a second connecting assembly 462, a third connecting assembly 463, a support assembly 47, a first square rod 481, a second square rod 482, and a third square rod 483; the dual-axis drive device 49 is mounted on the base frame 41, and one end of the drive rod 43 is connected to the left and right ends of the dual-axis drive device 49 respectively. The dual-axis drive device 49 is used to drive the two drive rods 43 to rotate. The dual-axis drive device 49 is equipped with a sensor, and the dual-axis drive device 49 is electrically connected to the sensor; the body of the drive rod 43 is provided with a crescent plate 431, which can be directly opposite the sensor. The other end of the drive rod 43 is hinged to one end of the first connecting rod 451 through the eccentric rotation assembly 44. The other end of the drive rod 43 is offset from one end of the first connecting rod 451. One end of the first connecting rod 451 moves eccentrically in a circular motion along the other end of the drive rod 43. The other end of the first connecting rod 451 is hinged to the first connecting component 461, which is mounted on the first square rod 481. The first square rod 481, the second square rod 482, and the third square rod 483 are rotatably mounted on the base frame 41. The first square rod 481 is located between the second square rod 482 and the third square rod 483. The first square rod 481 is equipped with the second connecting component 462. The second square rod 482 and the third square rod 483 are respectively equipped with the third connecting component 463. One end of the second connecting rod 452 is hinged to the second connecting component 462, and the other end is hinged to the third connecting component 463. The third square rod 483, the second square rod 482, and the first square rod 481 are each equipped with a plurality of support components 47, and the tops of the plurality of support components 47 are connected to the roller table 42. In this embodiment, the dual-axis drive device 49 is a dual-axis motor. The two output shafts of the dual-axis drive device 49 are respectively connected to the two gearboxes. The output end of the gearbox is connected to the drive rod 43. The drive rod 43 is rotatably mounted on the base frame 41. The second square rod 482 is located in front of the first square rod 481, and the third square rod 483 is located behind the first square rod 481. The first square rod 481 is equipped with two first connecting components 461 and two second connecting components 462. During operation, the dual-axis drive device 49 drives one end of the drive rod 43 to rotate through the gearbox. Specifically, when the dual-axis drive device 49 drives the drive rod 43 to rotate half a turn, the crescent-shaped plate 431 rotates 180° following the drive rod 43. At this time, the crescent-shaped plate 31 is aligned with the sensor (which can be a light sensor), and the sensor can feed back a signal to the dual-axis drive device 49, meaning that the roller table 42 is in a high position at this time.After a set time, the dual-axis drive device 49 drives the drive rod 43 to rotate half a turn. At this time, the crescent plate 431 is misaligned with the sensor, and the sensor sends a feedback signal to the dual-axis drive device 49. At this time, the roller table 42 is in a low position, thereby realizing the linkage between the position state of the dual-axis drive device 49 and the roller body 2. The other end of the drive rod 43 is connected to the end of the eccentric rotation assembly 44. One end of the first connecting rod 451 is hinged to the middle of the eccentric rotation assembly 44, so that the drive rod 43 causes one end of the first connecting rod 451 to perform eccentric circular motion through the eccentric rotation assembly 44. The other end of the first connecting rod 451 is hinged to the first connecting assembly 461. The first connecting component 461 is installed on the first square rod 481, allowing the first square rod 481 to rotate a certain angle following the push and pull of the first connecting rod 451. Furthermore, the first square rod 481 is also equipped with a second connecting component 462. The second square rod 482 and the third square rod 483 are respectively equipped with the third connecting component 463. The left and right sides of the second connecting component 462 are respectively hinged to the third connecting component 463 via two second connecting rods 452, allowing the second square rod 482 and the third square rod 483 to rotate synchronously with the first square rod 481. The first square rod 481 and the second square rod 483... Multiple support components 47 are respectively installed on the 82 and the third rod 483. The multiple support components 47 swing synchronously with the three square rods, that is, the roller table 42 can move up and down. In this embodiment, through the dual-axis drive device 49, the two drive rods 43, the two eccentric rotation components 44, the two first connecting rods 451 and the two first connecting components 461, compared with the single-axis output method, the dual-axis drive motor is used to achieve dual-axis output, which can not only reduce the load on the drive rods 43, improve their service life, and reduce the failure rate, but also ensure the rotational stability of the first square rod 481. Furthermore, through the second connecting rod 452, the second connecting component 462 and the third connecting component 461, the rotational stability of the first square rod 481 is achieved. The connecting component 463 causes the second square rod 482 and the third square rod 483 to rotate synchronously with the first square rod 481, with the first square rod 481 positioned between the first square rod 482 and the third square rod 483. Preferably, the first square rod 481 is located in the middle position between the first square rod 82 and the third square rod 483, ensuring that the output force of the two second connecting rods 452 is the same, thereby guaranteeing the lifting stability of the second conveying mechanism 4. Through the sensor and the crescent plate 431, the linkage between the dual-axis drive device 49 and the position state of the roller body 2 is realized, preventing the roller table 42 from starting to lift before the product has been completely conveyed, thus improving the working reliability of the second conveying mechanism 4.

[0061] like Figure 8-13As shown, the eccentric rotation assembly 44 includes a first clamping block 441, a second clamping block 442, an eccentric plate 443, and a first screw 444. The end of the drive rod 43 is connected to one side of the eccentric plate 443. The second clamping block 442 is mounted on one side of the eccentric plate 443. One side of the first clamping block 441 is mounted on the other side of the eccentric plate 443. The other side of the first clamping block 441 is hinged to a first connecting rod 451. The hinge point of the first clamping block 441 and the first connecting rod 451 is offset from the end of the drive rod 43. The end of the first screw 444 passes sequentially through the first clamping block 441 and the eccentric plate 443. 3. The end of the first screw 444 is installed inside the second clamping block 442, and the end of the first connecting rod 451 is hinged to the middle of the side of the first clamping block 441; the left and right sides of the eccentric plate 443 are respectively provided with mounting grooves 4431, and the first clamping block 441 and the second clamping block 442 are respectively installed in the two mounting grooves 4431; the mounting groove 4431 is connected by an adjustment groove 4432, the adjustment groove 4432 is arranged along the length direction of the mounting groove 4431, the end of the first screw 444 passes through the adjustment groove 431, and the end of the first screw 444 can move along the length direction of the adjustment groove 4432.

The first clamping block 441 and the second clamping block 442 clamp the eccentric plate 443 to achieve the purpose of locking. Finally, the end of the first connecting rod 451 is hinged to the middle of the side of the first clamping block 441, and the first clamping block 441 is offset from the end of the drive rod 43, so that the first connecting rod 451 can make eccentric circumferential motion along the end of the drive rod 43.In this embodiment, the width of the mounting groove 4431 is equal to the width of the first clamping block 441 and the width of the second clamping block 442, respectively. This means that the first clamping block 441 and the second clamping block 442 cannot move along the width direction. However, the length of the mounting groove 4431 is greater than the length of the first clamping block 441 and the second clamping block 442, meaning that the first clamping block 441 and the second clamping block 442 can move along the length direction of the mounting groove 4431. Specifically, during adjustment, the first screw 444 is loosened, causing the... The first clamping block 441 and the second clamping block 442 can move back and forth. The first screw 444 moves back and forth in the adjusting groove 4432. After the position is adjusted, the first screw 444 is turned to lock it, which is convenient and quick. In this embodiment, by adjusting the position of the first clamping block 441 and the second clamping block 442, the eccentric distance between the end of the first connecting rod 451 and the end of the driving rod 43 is adjusted, thereby controlling the lifting height of the roller table 42. It is suitable for lifting at different heights and achieves the effect of improving the versatility of the second conveying mechanism 4.

[0062] like Figure 11-13As shown, the second conveying mechanism 4 further includes an anti-displacement component 410, which is mounted on the eccentric plate 443. The end of the anti-displacement component 410 is connected to the second clamping block 442, and the anti-displacement component 410 is used to restrict the movement of the second clamping block 442. The anti-displacement component 410 includes an adjusting screw 4101, a connecting nut 4102, a third nut 4103, a fourth nut 4104, and a fifth nut 4105.

In this embodiment, during installation, the connecting nut 4102 and the third nut 4103 are respectively installed on one end of the adjusting screw 4101. One side of the connecting nut 4102 is connected to the second clamping block 442, while the other side of the connecting nut 4102 is locked and fixed by the third nut 4103. Then, the other end of the adjusting screw 4101 is installed on the mounting block 4433 of the eccentric plate 443, and the fourth nut 4104 and the fifth nut 4105 are respectively installed on the other end of the adjusting screw 4101, so that the fourth nut 4104 abuts against one side of the mounting block 4433, and the fifth nut 4105 abuts against the mounting block 4433. On the other hand, the fourth nut 4104 and the fifth nut 4105 clamp each other to lock and fix the adjusting screw 4101. During operation, the adjusting screw 4101 cannot move, so the connecting nut 4102 can restrict the movement of the second clamping block 442 to prevent changes in eccentricity. When it is necessary to move the second clamping block 442, the fourth nut 4104 and the fifth nut 4105 are loosened to allow the adjusting screw 4101 to move. Then the first screw 444 is loosened, and after adjustment, the first screw 444, the fourth nut 4104 and the fifth nut 4105 are locked in sequence to ensure the working stability of the second conveying mechanism 4.

Two first nuts 4614 are respectively mounted on the ends of the corresponding second screws 4613, thereby locking the first mounting rod 4611 and the second mounting rod 4612 to the first square rod 481. During operation, one end of the first connecting rod 451 performs an eccentric circular motion, and the other end of the first connecting rod 451 pulls the first mounting rod 4611 back and forth, thereby causing the first square rod 481 to rotate back and forth at a certain angle. It should be noted that the first connecting assembly 461 and the third connecting assembly 463 have the same structure. In this embodiment, the top of the third mounting rod 4621 is mounted on the rear side of the first square rod 481.

The two second nuts 4624 are respectively mounted on the ends of the corresponding two third screws 4623, thereby locking the third mounting rod 4621 and the fourth mounting rod 4622 to the first square rod 481. When the first square rod 481 rotates, the first square rod 481 drives the second square rod 482 and the third mounting rod 483 to rotate synchronously through the second connecting assembly 462 and the second connecting rod 452, thereby ensuring the lifting stability of the roller table 42.In this embodiment, the first square rod 481, the second square rod 482, and the third square rod 483 are each equipped with a plurality of support components 47. This embodiment uses the first square rod 481 as an example. During installation, the fifth mounting rod 471 is installed on the bottom surface of the first square rod 481, and the sixth mounting rod 472 is installed on the top surface of the second square rod 482. Two fourth screws 473 pass sequentially through the sixth mounting rod 472 and the fifth mounting rod 471. The bodies of the two fourth screws 473 abut against the front and rear sides of the first square rod 481, respectively. Two sixth nuts are installed at the ends of the corresponding fourth screws 473, thereby... The fifth mounting rod 471 and the sixth mounting rod 472 are locked to the first square rod 481. The end of the fifth mounting rod 471 is hinged to the hinge member 475, and the hinge member 475 is vertically arranged.

During operation, the first square rod 481, the second square rod 482 and the third square rod 483 rotate, thereby causing the multiple support components 47 to rotate accordingly. This causes the hinge members 475 of the support components 47 to rise and fall in the vertical direction, thereby causing the roller table 42 to rise and fall. The multiple support components 47 can ensure the stability of the roller table 42 in raising and lowering.

[0064] A control method for the edge grinding production line of double-piece ceramic tiles includes the following steps: Step 1: Two ceramic tiles are placed sequentially on the roller table 42 of the second conveying mechanism 4; Step 2: After passing through the second conveying zone 422 of the roller table 42, the first ceramic tile enters the first conveying zone 421, and the moving speed of the first ceramic tile decreases; Step 3: Under the action of the second conveying zone 422, the second ceramic tile quickly catches up with the first ceramic tile; Step 4: After both ceramic tiles reach the designated position of the roller table 2, the roller table 2 stops conveying, and the dual-shaft drive device 49 drives the roller table 42 to descend, and the two ceramic tiles follow the descent until they land on the top surface of multiple conveyor belts 5, and are positioned on the crescent-shaped plate. 31 and the feedback from the sensor, the dual-axis drive device 49 can know whether the roller table 2 is in a high position; Step 5: The sixth drive device drives multiple conveyor belts 5 to transport the two tiles to the first conveying mechanism 3; Step 6: When the first conveying mechanism 3 transports the two tiles past the photoelectric sensor, the photoelectric sensor feeds back information to the first conveying mechanism 3 and stops the first conveying mechanism 3; Step 7: The centering mechanism 2 performs centering processing on the two tiles; Step 8: After centering is completed, the first conveying mechanism 3 transports the two tiles to the first edge grinding mechanism 1; Step 9: The first edge grinding mechanism 1 grinds the top and bottom edges of the sides of the two tiles to form chamfers. In this embodiment, the roller table 42, the first conveying area 421, the second conveying area 422, the conveyor belt 5, the sixth drive device, and the dual-axis drive device 49 enable the second tile to quickly catch up with the first tile and transfer the two tiles at the corner, which is convenient and fast. Compared with the single-axis output method, the use of a dual-axis drive motor to achieve dual-axis output not only reduces the load on the output shaft of the dual-axis drive device 49, but also increases its service life and reduces the failure rate, thereby improving the production efficiency and service life of the edge grinding production line. It should be noted that whether the two tiles have reached the set position can be determined by position sensing. The device senses the position, and the position sensor is electrically connected to the roller table 2. Through the semi-circular plate 31 and the sensor, the linkage between the dual-axis drive device 49 and the position status of the roller body 2 is realized, which avoids the roller table 42 from starting to rise and fall before the product is completely conveyed, thereby improving the working reliability of the second conveying mechanism 4. The photoelectric sensor provides timely feedback on the conveying information of the two tiles, ensuring the working stability of the centering mechanism 2. With the assistance of the control system, the edge grinding production line of this application can simultaneously convey and transfer two tiles, simultaneously center two tiles, and simultaneously grind two tiles, thereby improving the production efficiency, production quality, and working stability of the edge grinding production line.
