In the present invention, a control box inside the main machine drives the output ends of the first motor and the second motor to respectively drive the engagement of the push plate mechanism and the ejection structure, so that the ejection structure and the round rod respectively lift and rotate the concave-convex plate, and then the concave-convex plate lifts the ceramic tiles on the surface under the elastic support of the bending structure, and then the ceramic tiles are driven by the concave-convex plate to rotate and swing to the right transmission device position.

Description

Technical Field

[0001] The invention relates to the field of ceramic tile manufacturing, in particular to a production process and production equipment for concave-convex ceramic tiles. Background Art

[0002] The production process of concave-convex tiles mainly includes raw material processing, tile forming, placement and drying, glazing and firing. The fired tiles also need to be post-processed to remove defective tiles. The key to the effect of concave-convex tiles lies in the fitting effect of the concave-convex texture. The formation of concave-convex texture mainly uses textured mold bricks in the mold forming stage. The raw materials are transported to the stamping area, lightly pressed to exhaust, and pressure is used to push the raw materials that have not yet solidified into shape into shape.

[0003] However, since there are lines on both the upper and lower surfaces of the concave and convex ceramic tiles, during demoulding, the mold is fixed up and down, and the tiles can only be pushed out from the bottom of the mold. After the tiles are pushed out, they cannot be pushed out horizontally due to the obstruction of the concave and convex lines, and manual transfer is required, which is too inconvenient. In addition, when the tiles are pushed out of the mold, due to the concave and convex lines, the thickness of some parts of the tiles is thinner. When the tiles are pushed out of the mold, they will rub against the four inner walls of the mold. Excessive friction on the four inner walls will cause damage to the edges of the tiles, and excessive friction will easily cause the thinner parts of the tiles to break. Summary of the Invention

[0004] The present invention provides a production process and production equipment for concave-convex ceramic tiles, which overcome the deficiencies described in the background art.

[0005] The technical solution adopted by the present invention to solve its technical problem is:

[0006] A production device for concave-convex tiles, comprising a lower mold mechanism, a main machine, a transmission device, a hydraulic pressure device, a base, and a rotator. The lower end of the rotator is provided with a material delivery pipe, which rotates at the output end of the rotator, and the outer side of the rotator is located above the lower mold mechanism. The lower mold mechanism is arranged inside the base, and a hydraulic pressure device fixed inside the main machine is provided at a corresponding position above the lower mold mechanism, driving the output end of the hydraulic pressure device to extend and retract and push against the middle of the lower mold mechanism. The transmission device is located on the surface of the base and drives the lower mold mechanism to transfer the tiles above to the surface of the transmission device.

[0007] The lower mold mechanism is provided with a hydraulic pusher, a transfer mechanism, a concave plate, a mold plate and a base. The base is horizontally fixed on the surface of the base. There are two mold plates, which are symmetrically arranged on the left and right sides of the base. The hydraulic pusher telescopes and pushes the concave plate to squeeze the mold plate, so that the mold plate rotates and opens and closes in the base. The transfer mechanism is located inside the base and drives the transfer mechanism to transfer the tiles above the base to the surface of the transmission device for transmission.

[0008] A better technical solution: The transfer mechanism is provided with a lifting mechanism, a support plate, a first motor and a second motor. Two second motors are provided, which are respectively arranged on the sides of the support plates on both sides, and the support plates are arranged parallel to the inner side of the base. The output end of the second motor engages to drive the lifting mechanism to move up and down, and the output end of the first motor engages to push the lifting mechanism to swing and transfer the upper tiles. A spring bar is provided at the upper end of the concave plate, and the concave plate is fixed to the lower end of the mold plate through the spring bar. When the output end of the hydraulic pusher pushes the concave plate to extend and retract, it drives the spring bar to rotate and open and close the mold plate.

[0009] A preferred technical solution: The lifting mechanism is provided with a push plate mechanism, a concave-convex plate, a round rod and an ejection structure. There are two round rods, which are arranged parallel to each other on the inner side of the base. The output end of the second motor drives the ejection structure to slide between the two round rods. The push plate mechanism moves up and down inside the ejection structure. The output end of the first motor drives the push plate mechanism to swing the concave-convex plate.

[0010] A better technical solution: The ejection structure is provided with a bending structure, a slide groove, a connecting rod, a track plate, a supporting structure, a fixed rod and a rotating shaft. The bending structure is obliquely connected between the concave-convex plate and the track plate, and the concave-convex plate is connected to the track plate at an angle through the rotating shaft. The fixed rod passes through the slide groove inside the track plate and is fixed on the inner side of the supporting structure. The connecting rod is movably connected on the inner side of the lower end of the track plate. When the connecting rod moves upward, the track plate moves linearly along the direction of the fixed rod through the slide groove, and the concave-convex plate is lifted by the support of the rotating shaft and the bending structure.

[0011] A better technical solution: the supporting structure is provided with a gear plate, a limit bar, a rail groove and a guide bar. The limit bar is arranged at the upper end of the gear plate, and two are provided respectively, and the fixing rod is connected between the two limit bars. The limit bar and the gear plate are connected in parallel by the fixing rod. The guide bar is arranged on the inner side of the limit bar along the inclination angle of the track plate. The rail groove is located on the inner side of the limit bar, and the push plate mechanism rises and falls and slides through the rail groove.

[0012] A better technical solution: the push plate mechanism is provided with a gear bar and a flat plate, the flat plate is connected to the lower end of the track plate through a connecting rod, the gear bar is located on the side of the flat plate, and the flat plate rises and falls and slides in the rail groove position within the two limit bars, and the rightmost side of the gear bar and the rightmost side of the gear plate are located in adjacent vertical positions.

[0013] A better technical solution: four plastic plates are provided on the inner side of the support plate, and the plastic plates are symmetrically distributed on the outside of the limiting strip, and the round rods and the quadrilateral correspond to the outside of the limiting strip.

[0014] A better technical solution: The bending structure is provided with a force-bearing plate, a hinge shaft and a spring. There are two force-bearing plates, which swing on the hinge shafts respectively. The two ends of the spring are fixed in a curved shape on the sides of the two force-bearing plates. When the spring is in a stationary state, the two force-bearing plates are located in the same straight line.

[0015] A production process for concave-convex tiles, based on the above-mentioned production equipment for concave-convex tiles, has the following specific production process steps:

[0016] S1: The output end of the rotator rotates and drives the feeding pipe above the lower mold mechanism, feeding the raw materials into the lower mold mechanism through the feeding pipe. After the feeding is completed, the rotator drives the feeding pipe to separate from the top of the lower mold mechanism, and then drives the hydraulic press to retract into the lower mold mechanism to stamp the raw materials into tiles;

[0017] S2: After the tile is formed, the hydraulic press is driven to extend and retract upward to separate from the lower mold mechanism, and then the hydraulic pusher drives the concave plate and drives the spring bar to rotate and open the mold plate, so that the two mold plates are separated from the sides of the tile on both sides of the base, and the output end of the second motor is driven to drive the ejection structure, so that the support structure in the ejection structure is guided by the round rod and the plastic plate to move upward in a straight line. Then, while the support structure moves upward, it drives the push plate mechanism to move upward through the connecting rod, so that the concave and convex plate drives the tile to lift and move upward under the support of the bending structure;

[0018] S3: After the tiles are lifted, the output end of the first motor engages to drive the gear bar in the push plate mechanism, and the flat plate lifts the lower end of the track plate through the connecting rod, so that the lower end of the track plate generates an upward force, and then the slide groove inside the track plate moves linearly along the direction of the fixed rod. At this time, the track plate uses the fixed rod as a support point and is controlled to swing by the upper end of the connecting rod, and the concave and convex plate is kept in a horizontal state by the bending elastic force of the spring;

[0019] S4: When the track plate swings to the point where the fixed rod cannot slide in the slide groove, the connecting rod will continue to push the lower end of the track plate upwards. At this time, the track plate rotates clockwise with the fixed rod as the center. After the track plate rotates, the concave-convex plate is tilted toward the transmission device under the elastic action of the bending structure, and the right side of the tile on the surface of the concave-convex plate first contacts the surface of the transmission device. Then, as the track plate continues to rotate, the concave-convex plate will rotate to a vertical state with the rotating shaft as the center under the elasticity of the bending structure, and the tile will gradually separate from the surface of the concave-convex plate from right to left through the elastic force of the bending structure, and the right side of the tile is supported by the transmission device and the left side is supported by the concave-convex plate. Then, under the elastic force of the bending structure, the concave-convex plate will elastically push the tile away, and at the same time, the tile will be transmitted to the next processing link under the transmission of the transmission device.

[0020] Compared with the existing technology, this technical solution has the following advantages:

[0021] In the present invention, the control box inside the main unit drives the output ends of the first motor and the second motor to engage with the push plate mechanism and the ejection structure respectively, so that the ejection structure and the round rod lift and rotate and swing the concave-convex plate respectively, and then the concave-convex plate lifts the tiles on the surface under the elastic support of the bending structure, and then the tiles are driven by the concave-convex plate to rotate and swing to the right position of the transmission device, so that the right side of the tile is against the surface of the transmission device, and the concave-convex plate is in an inclined state under the continuous rotation and swinging of the track plate. During this process, the concave and convex parts of the tile gradually separate from the surface of the concave-convex plate, and then the concave-convex plate generates a pushing force to the right under the elastic limit of the bending structure, so that the tile is guided by the concave-convex plate to the surface of the transmission device, and the transfer of the concave and convex tiles is realized under the transmission of the transmission device, avoiding the concave and convex parts of the tile from blocking the transfer and preventing the concave and convex parts of the tile from causing inconvenience in transfer.

[0022] The present invention drives the output end of the hydraulic pusher to extend and retract and push the concave plate, so that the spring strip on the upper end of the concave plate drives the "L"-shaped right-angled edge of the mold plate, so that the mold plate rotates outward with the corner as the center, so that the mold plate opens and closes on both sides of the tile forming position of the lower mold mechanism, thereby reducing the friction on both sides of the tile. When the concave-convex plate drives the tile to move upward, only the friction on both sides can facilitate the demolding of the tile, avoiding damage to the edge of the tile caused by excessive friction on the formed tile, and avoiding breakage of the thinner part of the tile caused by excessive friction when lifting the tile.

DETAILED DESCRIPTION

[0035] like Figures 1 to 10 As shown, the present invention proposes a production equipment for concave-convex tiles, including a lower mold mechanism 1, a main machine 2, a transmission device 3, a hydraulic press 4, a base 5 and a rotator 6. The lower end of the rotator 6 is provided with a material delivery pipe, which rotates at the output end of the rotator 6, and the outer side of the rotator 6 is located above the lower mold mechanism 1. The lower mold mechanism 1 is arranged inside the base 5, and a hydraulic press 4 fixed inside the main machine 2 is provided at a corresponding position above the lower mold mechanism 1. The output end of the hydraulic press 4 is driven to extend and retract and push the middle of the lower mold mechanism 1. The transmission device 3 is located on the surface of the base 5 and drives the lower mold mechanism 1 to transfer the tiles above to the surface of the transmission device 3.

[0036] The lower mold mechanism 1 is provided with a hydraulic pusher 11, a transfer mechanism 12, a concave plate 13, a mold plate 14 and a base 15. The base 15 is horizontally fixed on the surface of the base 5. The mold plates 14 are provided with two, which are symmetrically arranged on the left and right sides of the base 15. The hydraulic pusher 11 telescopically pushes the concave plate 13 to squeeze the mold plate 14, so that the mold plate 14 rotates and opens and closes in the base 5. The transfer mechanism 12 is located inside the base 5, and drives the transfer mechanism 12 to transfer the tiles above the base 15 to the surface of the transmission device 3 for transmission.

[0037] In addition, the middle of the transmission device 3 is hollow. When the concave-convex plate 212 rotates to the limit following the track plate 44, the right part of the concave-convex plate 212 is located below the transmission device 3, and the mold plate 14 is in an "L"-shaped state. When it is stationary, the "L"-shaped right-angled side of the mold plate 14 is in a vertical state. The mold plate 14 rotates around the "L"-shaped corner, and the rotation angle is less than 45°. The lower end of the hydraulic press 4 is provided with an upper mold corresponding to the lower mold mechanism 1. By driving the hydraulic press 4 to extend and retract, the upper mold corresponds to the center position of the lower mold mechanism 1 to punch the raw material.

[0038] Among them, the transfer mechanism 12 is provided with a lifting mechanism 121, a support plate 122, a first motor 123 and a second motor 124. There are two second motors 124, which are respectively arranged on the sides of the support plate 122 on both sides, and the support plate 122 is arranged parallel to the inner side of the base 5. The output end of the second motor 124 engages to drive the lifting mechanism 121 to move up and down, and the output end of the first motor 123 engages to push the lifting mechanism 121 to swing and transfer the upper tiles. The upper end of the concave plate 13 is provided with a spring bar 101, and the concave plate 13 is fixed to the lower end of the mold plate 14 through the spring bar 101. When the output end of the hydraulic pusher 11 pushes the concave plate 13 to retract and retract, it drives the spring bar 101 to rotate and open and close the mold plate 14.

[0039] In addition, the second motor 124 and the first motor 123 are respectively electrically connected to the inside of the main machine 2, and the hydraulic press 4, the rotator 6 and the hydraulic pusher 11 are respectively electrically connected to the inside of the main machine 2. A control box is provided inside the main machine 2 to electrically drive the hydraulic press 4, the rotator 6, the hydraulic pusher 11, the first motor 123 and the second motor 124.

[0040] Among them, the lifting mechanism 121 is provided with a push plate mechanism 211, a concave-convex plate 212, a round rod 213 and an ejection structure 214. There are two round rods 213, which are arranged parallel to each other on the inner side of the base 5. The output end of the second motor 124 drives the ejection structure 214 to slide between the two round rods 213. The push plate mechanism 211 moves up and down inside the ejection structure 214. The output end of the first motor 123 drives the push plate mechanism 211 to swing the concave-convex plate 212.

[0041] Among them, the ejection structure 214 is provided with a bending structure 41, a slide groove 42, a connecting rod 43, a track plate 44, a supporting structure 45, a fixing rod 46 and a rotating shaft 47. The bending structure 41 is obliquely connected between the concave-convex plate 212 and the track plate 44, and the concave-convex plate 212 is connected to the track plate 44 at an angle through the rotating shaft 47. The fixing rod 46 passes through the slide groove 42 inside the track plate 44, and the fixing rod 46 is fixed on the inner side of the supporting structure 45. The connecting rod 43 is movably connected on the inner side of the lower end of the track plate 44. When the connecting rod 43 moves upward, the track plate 44 moves linearly along the direction of the fixing rod 46 through the slide groove 42, and lifts the concave-convex plate 212 through the support of the rotating shaft 47 and the bending structure 41.

[0042] In addition, the concave-convex plate 212 is in a square state. When the concave-convex plate 212 is on the surface of the base 15, the base 15 supports the concave-convex plate 212 to keep it horizontal. The connection between the concave-convex plate 212 and the ejection structure 214 is located on the right side of the concave-convex plate 212. When the ejection structure 214 lifts the concave-convex plate 212, the tiles on the surface of the concave-convex plate 212 will cause the concave-convex plate 212 to rotate counterclockwise around the rotating shaft 47 under gravity. When the ejection structure 214 is lifted upward, the concave-convex plate 212 is kept in a horizontal state with the support of the bending structure 41. When the track plate 44 rotates, the center of gravity of the concave-convex plate 212 shifts to the left, and the concave-convex plate 212 squeezes the bending structure 41. Before the track plate 44 rotates halfway, the concave-convex plate 212 remains in a horizontal state with a 10° tilt when following the track plate 44 to eject and rotate upward, so as to prevent the concave-convex plate 212 from tilting more than 10° when the tiles are not ejected.

[0043] Moreover, the track plate 44 is tilted 5° from the vertical line when it is in a stationary state, and when the connecting rod 43 lifts the track plate 44, the track plate 44 is limited by the sliding of the fixed rod 46 in the slide groove 42, so that the track plate 44 rotates a certain amount during the upward lifting process (such as the attached Figure 6 ), when the fixing rod 46 is located at the lowest end of the slide groove 42, it will be blocked, and then the track plate 44 will rotate around the fixing rod 46 as the center under the continued lifting of the connecting rod 43.

[0044] Among them, the support structure 45 is provided with a gear plate 451, a limit bar 452, a rail groove 453 and a guide bar 454. The limit bar 452 is arranged at the upper end of the gear plate 451, and two are provided respectively, and the fixing rod 46 is connected between the two limit bars 452. The limit bar 452 and the gear plate 451 are connected in parallel through the fixing rod 46. The guide bar 454 is arranged on the inner side of the limit bar 452 along the inclination angle of the track plate 44. The rail groove 453 is located on the inner side of the limit bar 452, and the push plate mechanism 211 rises and falls and slides through the rail groove 453.

[0045] In addition, the guide bar 454 is located on the right side of the track plate 44, which has the effect of keeping the track plate 44 in a left-tilted state, wherein the guide bar 454 is on the inner side of the limit bars 452 on both sides, and the guide bar 454 is connected in the middle position of the limit bars 452, which has the effect of supporting the two limit bars 452 and the gear plate 451 to be parallel, and the middle position is connected to prevent the track plate 44 from being blocked when it moves upward and rotates, and to prevent the gear bar 31 from being blocked when it moves upward between the two limit bars 452.

[0046] In addition, the gear plate 451 is in an "L"-shaped state on the side close to the round rod 213, and the round rod 213 is located on the right-angled side of the "L". When the gear plate 451 is limited in a quadrilateral by the two round rods 213 and the plastic plates 102 inside the two support plates 122, the gear plate 451 can only slide up and down. When the gear plate 451 slides upward to the limit, it will be blocked by the round rod 213 at the "L"-shaped position of the gear plate 451. At this time, the output end of the second motor 124 and the gear plate 451 maintain a gear-fixed state, ensuring that the gear plate 451 and the limit bar 452 remain vertically fixed.

[0047] Among them, the pushing plate mechanism 211 is provided with a gear bar 31 and a flat panel 32. The flat panel 32 is connected to the lower end of the track plate 44 through a connecting rod 43. The gear bar 31 is located on the side of the flat panel 32, and the flat panel 32 rises and falls and slides in the rail groove 453 position within the two limit bars 452. The rightmost side of the gear bar 31 and the rightmost side of the gear plate 451 are located in adjacent vertical positions.

[0048] Among them, four plastic plates 102 are provided inside the support plate 122 , and the plastic plates 102 are symmetrically distributed outside the limiting strip 452 , and the round rods 213 and 103 are quadrilaterals corresponding to the outside of the limiting strip 452 .

[0049] Among them, the bending structure 41 is provided with a force-bearing plate 411, a hinge shaft 412 and a spring 413. There are two force-bearing plates 411, which hinge and swing on the hinge shaft 412 respectively. The two ends of the spring 413 are fixed in a curved shape on the sides of the two force-bearing plates 411. When the spring 413 is in a stationary state, the two force-bearing plates 411 are located in the same straight line.

[0050] Furthermore, the force-bearing plate 411 connected to the track plate 44 is in a fixed state. Under the elastic force of the spring 413 , the force-bearing plate 411 supports the concave-convex plate 212 to tilt toward a vertical state.

[0051] In addition, the first motor 123 and the side of the gear bar 31 in the push plate mechanism 211 engage and rotate, driving the flat plate 32 in the push plate mechanism 211 to slide on the track groove 453 on the inner side of the limit bar 452. It is necessary to explain that when the second motor 124 engages to drive the ejection structure 214 to move upward, the ejection structure 214 will drive the push plate mechanism 211 to pull upward through the position of the connecting rod 43. At this time, the side of the gear bar 31 in the push plate mechanism 211 remains engaged with the output end of the first motor 123, but the first motor 123 is in a non-working state at this time. However, the output end of the first motor 123 can be driven by the movement of the gear bar 31 to engage and rotate clockwise. When the second motor 124 drives the ejection structure 214 to complete the engagement and rotation, the first motor 123 will start working.

[0052] Moreover, the maximum rotation angle of the two force-bearing plates 411 around the hinge shaft 412 is 90 degrees. Since the force-bearing plates 411 connected to the track plate 44 remain fixed, when the two force-bearing plates 411 are in the rotation limit state, the tension of the two force-bearing plates 411 on the spring 413 is also in the limit state, and at this time, the concave-convex plate 212 is tilted nearly 90 degrees under the limit support of the bending structure 41, and the track plate 44 is rotated clockwise to a limit angle of 30 degrees. At the same time, the ceramic on the surface of the concave-convex plate 212 is The right side of the tile rests against the surface of the transmission device 3, while the concave and convex parts of the tile are separated from the surface of the concave and convex plate 212. Only the left side of the tile is supported by the concave and convex plate 212. At this time, the spring 413 will generate an ultimate elastic force of tension and expand the angle between the two force-bearing plates 411, thereby supporting the concave and convex plate 212 to rotate toward a vertical state, so that the concave and convex plate 212 generates a lateral pushing force on the surface tiles, and then the tiles are separated from the surface of the concave and convex plate 212 and enter the surface of the transmission device 3. After the tiles are transferred, the transfer mechanism 12 and the mold plate 14 are reset.

[0053] In the present invention, the control box inside the main unit 2 drives the output ends of the first motor 123 and the second motor 124 to engage and drive the push plate mechanism 211 and the ejection structure 214 respectively, so that the ejection structure 214 and the round rod 213 respectively lift and rotate the concave-convex plate 212, and then the concave-convex plate 212 lifts the tiles on the surface under the elastic support of the bending structure 41, and then the tiles are driven by the concave-convex plate 212 to rotate and swing to the position of the transmission device 3 on the right, so that the right side of the tiles are against the surface of the transmission device 3, and the concave-convex plate 212 is in an inclined state under the continuous rotation and swing of the track plate 44. During this process, the concave and convex parts of the tiles gradually separate from the surface of the concave-convex plate 212, and then the concave-convex plate 212 generates a pushing force to the right under the elastic limit of the bending structure 41, so that the tiles are guided to the surface of the transmission device 3 by the concave-convex plate 212, and the concave-convex tiles are transferred under the transmission of the transmission device 3, avoiding the concave and convex parts of the tiles from blocking the transfer and preventing the concave and convex parts of the tiles from causing inconvenience in transfer.

[0054] In the present invention, by driving the output end of the hydraulic pusher 11 to extend and retract and push the concave plate 13, the spring bar 101 at the upper end of the concave plate 13 drives the "L"-shaped right-angled side of the mold plate 14, so that the mold plate 14 rotates outward with the corner as the center, so that the mold plate 14 opens and closes the two sides of the tile forming position of the lower mold mechanism 1, thereby reducing the friction on both sides of the tile. When the concave-convex plate 212 drives the tile upward, only the friction on both sides can facilitate the demolding of the tile, avoiding excessive friction on the formed tile causing damage to the tile edge, and avoiding excessive friction when lifting the tile causing breakage of the thinner part of the tile.

[0055] A production process for concave-convex tiles, based on the above-mentioned production equipment for concave-convex tiles, has the following specific production process steps:

[0056] S1: The output end of the rotator 6 rotates and drives the feeding pipe above the lower mold mechanism 1, and the raw materials are fed into the lower mold mechanism 1 through the feeding pipe. After the feeding is completed, the rotator 6 drives the feeding pipe to separate from the upper part of the lower mold mechanism 1, and then drives the hydraulic press 4 to retract into the lower mold mechanism 1 to stamp the raw materials into tiles;

[0057] S2: After the tile is formed, the hydraulic press 4 is driven to extend and retract upward to separate from the lower mold mechanism 1, and then the hydraulic pusher 11 drives the concave plate 13, and drives the spring bar 101 to rotate and open the mold plate 14, so that the two mold plates 14 are separated from the sides of the tile on both sides of the base 15, and the output end of the second motor 124 is driven to drive the ejection structure 214, so that the support structure 45 in the ejection structure 214 is guided by the round rod 213 and the plastic plate 102 to move upward in a straight line. Then, while the support structure 45 moves upward, it drives the push plate mechanism 211 to move upward through the connecting rod 43, so that the concave and convex plate 212 drives the tile to lift and move upward under the support of the bending structure 41;

[0058] S3: After the tiles are lifted, the output end of the first motor 123 engages to drive the gear bar 31 in the push plate mechanism 211, and causes the flat plate 32 to lift the lower end of the track plate 44 through the connecting rod 43, so that the lower end of the track plate 44 generates an upward force, and then the slide groove 42 inside the track plate 44 moves linearly along the direction of the fixed rod 46. At this time, the track plate 44 uses the fixed rod 46 as a support point and is controlled to swing by the upper end of the connecting rod 43, and the concave-convex plate 212 is kept in a horizontal state by the bending elastic force of the spring 413;

[0059] S4: When the track plate 44 swings to the point where the fixed rod 46 cannot slide in the slide groove 42, the connecting rod 43 will continue to push the lower end of the track plate 44 upward. At this time, the track plate 44 rotates clockwise with the fixed rod 46 as the center. After the track plate 44 rotates, the concave-convex plate 212 is tilted to the transmission device 3 under the elastic action of the bending structure 41, and the right side of the tile on the surface of the concave-convex plate 212 first contacts the surface of the transmission device 3. Then, as the track plate 44 continues to rotate, the concave-convex plate 212 will rotate to a vertical state with the rotating shaft 47 as the center under the elastic action of the bending structure 41. Then, the elastic force of the bending structure 41 will cause the tile to gradually separate from the surface of the concave-convex plate 212 from right to left, and then the right side of the tile is supported by the transmission device 3 and the left side is supported by the concave-convex plate 212. Then, under the elastic force of the bending structure 41, the concave-convex plate 212 will elastically push the tile away, and at the same time, the tile is transmitted to the next processing link under the transmission of the transmission device 3.

In other words, equivalent changes and modifications made according to the scope of the present invention and the contents of the specification should still fall within the scope of the present invention.
