Description

Technical Field

[0001] The utility model belongs to the technical field of tile production, and specifically relates to a double-sided grinding device for tiles. Background Art

[0002] Tiles, also known as ceramic tiles, are made of refractory metal oxides and semi-metal oxides through processes such as grinding, mixing, pressing, glazing, and sintering, and form an acid and alkali-resistant porcelain or stone-like building or decorative material, called tiles. Their raw materials are mostly mixed from clay, quartz sand, etc. Existing tiles generally only grind and polish the smooth surface, but the rough surface of some tiles often has unstable quality, with burrs or unevenness. In addition, some ultra-thin tiles also need to grind their rough surfaces to make them flat, so as to improve the accuracy when tiling.

[0003] CN201811431759.X discloses a tile grinding device, which includes a conveyor belt for transporting tiles back and forth, a grinding plate for grinding the tile surface, and a rotating arm for driving the grinding plate to move horizontally; the grinding plate is installed above the conveyor belt through a mounting frame; a rotating motor is arranged on one side of the conveyor belt; one end of the rotating arm is connected to the rotating motor, and the other end is connected to the grinding plate.

[0004] In the above technical solution, by driving the rotation of the rotating arm by the rotating motor, the grinding plate connected to the rotating arm can move back and forth left and right in the mounting frame to complete the grinding of the upper surface of the tile. However, such a grinding method can only grind one side of the tile, and the other side cannot be ground;

[0005] Moreover, during the process of the conveyor belt transporting the tiles, the grinding plate moves horizontally and repeatedly. When the tile gradually passes through the grinding plate, the grinding plate may start to move horizontally for grinding at a place that is not at the edge of the tile. Then, the grinding plate cannot grind the edge of the tile, resulting in incomplete grinding. Content of the Utility Model

[0006] The purpose of the utility model is to solve the above problems, and provides a double-sided grinding device for tiles. The device simultaneously grinds the upper surface and the lower surface of the tile through the provided upper grinding mechanism and lower grinding mechanism. After the upper grinding mechanism and the lower grinding mechanism complete the grinding of the tile on the first conveying mechanism, the tile will be conveyed to the second conveying mechanism, and the grinding unit will grind the edge of the tile surface, which can simultaneously and comprehensively complete the grinding of both sides of the tile without incomplete grinding, improving the tile production efficiency.

[0007] To achieve the above purpose, the utility model provides the following technical solutions:

[0008] A double-sided grinding device for tiles, comprising a frame and a driving mechanism. The frame is provided with a first conveying mechanism and a second conveying mechanism connected in sequence, and an upper grinding mechanism for grinding the upper surface of the tile. The upper grinding mechanism is located above the first conveying mechanism. The device further comprises a lower grinding mechanism. The driving mechanism is connected to the lower grinding mechanism. The lower grinding mechanism is arranged between the first conveying mechanisms and is located below the upper grinding mechanism. The driving mechanism is used to drive the lower grinding mechanism to reciprocate left and right to grind the lower surface of the tile.

[0009] The frame is further provided with grinding units, which are located on both sides along the conveying direction of the second conveying mechanism. The grinding units are used to grind the edges of the tile surface.

[0010] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0011] In the present utility model, when the first conveying mechanism conveys the tile, the upper grinding mechanism and the lower grinding mechanism are arranged to grind the upper surface and the lower surface of the tile simultaneously. After the upper grinding mechanism and the lower grinding mechanism complete the grinding of the tile on the first conveying mechanism, the tile will be conveyed to the second conveying mechanism, and the grinding units will grind the edges of the tile surface. The two sides of the tile can be ground simultaneously and comprehensively, and the situation of incomplete grinding will not occur, improving the production efficiency of the tile.

Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0020] Embodiment 1

[0021] Refer to Figures 1 to 5 , a double-sided grinding device for ceramic tiles, including a frame 1 and a driving mechanism 2. The frame 1 is provided with a first conveying mechanism 11 and a second conveying mechanism 12 that are sequentially connected, and an upper grinding mechanism 13 for grinding the upper surface of the ceramic tile. The upper grinding mechanism 13 is located above the first conveying mechanism 11. It also includes a lower grinding mechanism 14. The driving mechanism 2 is connected to the lower grinding mechanism 14. The lower grinding mechanism 14 is arranged between the first conveying mechanisms 11 and is located below the upper grinding mechanism 13. The driving mechanism 2 is used to drive the lower grinding mechanism 14 to reciprocate left and right to grind the lower surface of the ceramic tile;

[0022] The frame 1 is further provided with a grinding unit 15. The grinding unit 15 is located on both sides along the conveying direction of the ceramic tile by the second conveying mechanism 12. The grinding unit 15 is used to grind the edges of the surface of the ceramic tile.

[0023] It should be noted here that when the first conveying mechanism 11 conveys the ceramic tile, the first conveying mechanism 11 supports both sides of the bottom of the ceramic tile to make the middle of the ceramic tile suspended, while the second conveying mechanism 12 conveys the ceramic tile by supporting the middle of the bottom of the ceramic tile to make both sides of the bottom of the ceramic tile suspended.

[0024] Under this design, the first conveying mechanism 11 gradually conveys the tiles and makes them gradually pass through between the upper grinding mechanism 13 and the lower grinding mechanism 14. During the process of the tiles passing through, the upper grinding mechanism 13 grinds the upper surface of the tiles, and for the lower surface of the tiles, the lower grinding mechanism 14 is driven by the driving mechanism 2 to reciprocate left and right to complete the grinding of the lower surface of the tiles. After passing through the upper grinding mechanism 13 and the lower grinding mechanism 14, the tiles on the first conveying mechanism 11 will be conveyed onto the second conveying mechanism 12. During the process on the second conveying mechanism 12, the tiles will gradually pass through the grinding unit 15, and the grinding unit 15 grinds the surface edge parts that the upper grinding mechanism 13 and the lower grinding mechanism 14 fail to grind, so as to complete the double-sided grinding of the tiles. In this way, the two sides of the tiles can be ground simultaneously and comprehensively, without the situation of incomplete grinding, improving the tile production efficiency.

[0025] Preferably, the upper grinding mechanism 13 includes a first fixing frame 132 connected to the frame 1, a first rotating motor 131 connected to the first fixing frame 132, and a grinding plate 133 connected to the output end of the first rotating motor 131. The grinding plate 133 is located above the first conveying mechanism 11, and the first rotating motor 131 is used to drive the grinding plate 133 to rotate to grind the upper surface of the tiles on the first conveying mechanism 11;

[0026] Specifically, the first rotating motor 131 provides power to drive the grinding plate 133 to rotate. When the first conveying mechanism 11 conveys the tiles past the upper grinding mechanism 13, the rotating grinding plate 133 contacts the surface of the tiles. Under the action of the rotation of the grinding plate 133, the surface of the tiles can be ground more evenly, and the uneven parts on the tile surface will be ground off by the rotating grinding plate 133, making the tile surface smooth and uniform.

[0027] In this embodiment, the lower grinding mechanism 14 includes a second fixing frame 141, a mounting frame 142, a mounting frame 143, and a plurality of first grinding rollers 144 arranged at intervals in the mounting frame 143. The second fixing frame 141 is connected to the frame 1, the mounting frame 142 is connected to the second fixing frame 141, sliding grooves 1421 are provided on both sides inside the mounting frame 142, and the mounting frame 143 is slidably connected inside the mounting frame 142 through a plurality of pulleys 1431 provided on both sides and matching with the sliding grooves 1421. A connecting member 1432 is further provided at the bottom of the mounting frame 143. The driving mechanism 2 is connected to the second fixing frame 141 and is connected to the connecting member 1432. The driving mechanism 2 is used to drive the mounting frame 143 to reciprocate left and right so that the first grinding rollers 144 contact the lower surface of the tiles for grinding;

[0028] Specifically, by connecting the driving mechanism 2 to the connecting member 1432 of the mounting frame 143, and providing power by the driving mechanism 2, the mounting frame 143 can reciprocate left and right within the mounting bracket 142, thereby driving multiple first grinding rollers 144 to move. In this way, under the reciprocating movement of the first grinding rollers 144, uneven parts on the lower surface of the ceramic tile will be ground off by the first grinding rollers 144, making the lower surface of the ceramic tile smooth and uniform. Moreover, by providing pulleys 1431 on both sides of the mounting frame 143 that match the sliding grooves 1421 of the mounting bracket 142, the noise generated during the movement of the mounting frame 143 can be reduced, and the movement of the mounting frame 143 can also become more smooth and stable.

[0029] More preferably, the driving mechanism 2 includes a second rotating motor 21, a rotating rod 22, and a connecting rod 23. The second rotating motor 21 is connected to the second fixing frame 141. The rotating rod 22 is connected to the power output end of the second rotating motor 21. One end of the connecting rod 23 is hinged to the rotating rod 22, and the other end is hinged to the connecting member 1432.

[0030] Further, one end of the connecting rod 23 is hinged to the connecting member 1432 of the mounting frame 143, and the other end is hinged to the rotating rod 22. The second rotating motor 21 provides power to drive the rotation of the rotating rod 22, thereby driving the mounting frame 143 to reciprocate, so that the first grinding rollers 144 on the mounting frame 143 can grind the lower surface of the ceramic tile.

[0031] More preferably, the grinding unit 15 includes a first grinding assembly 151 and a second grinding assembly 152 connected to the machine frame 1. The first grinding assembly 151 and the second grinding assembly 152 are respectively located on both sides along the conveying direction of the ceramic tile by the second conveying mechanism 12.

[0032] Specifically, the first grinding assembly 151 and the second grinding assembly 152 are respectively arranged on both sides along the conveying direction of the ceramic tile by the second conveying mechanism 12. In this way, when the ceramic tile on the second conveying mechanism 12 gradually passes through the first grinding assembly 151 and the second grinding assembly 152, the edges of the ceramic tile can be ground.

[0033] In this embodiment, the first grinding assembly 151 includes a first mounting base 1511, a second mounting base 1512, a plurality of second grinding rollers 1513, and a plurality of third grinding rollers 1514. The first mounting base 1511 is connected to the frame 1. The first mounting base 1511 is provided with a first lifting mechanism 1515. The second mounting base 1512 is connected to the power output end of the first lifting mechanism 1515. The second grinding rollers 1513 are arranged at intervals on the first mounting base 1511 along the direction in which the second conveying mechanism 12 conveys the tiles. The tops of the second grinding rollers 1513 are on the same horizontal plane as the conveying plane of the second conveying mechanism 12. The third grinding rollers 1514 are arranged at intervals on the second mounting base 1512 along the direction in which the second conveying mechanism 12 conveys the tiles. The third grinding rollers 1514 are located above the second grinding rollers 1513;

[0034] The first lifting mechanism 1515 is used to drive the second mounting base 1512 to descend so that the third grinding rollers 1514 contact the upper surface of the tiles on the second conveying mechanism 12.

[0035] Specifically, the second conveying mechanism 12 gradually conveys the tiles. When the tiles on the second conveying mechanism 12 approach the second grinding rollers 1513, the first lifting mechanism 1515 provided on the first mounting base 1511 drives the second mounting base 1512 to descend, thereby causing the third grinding rollers 1514 to descend. In this way, under the continuous conveying of the second conveying mechanism 12, the lower surface of the tiles will contact the tops of the second grinding rollers 1513, and the upper surface of the tiles will contact the third grinding rollers 1514 to complete the grinding of the tiles. After the tiles leave the second grinding rollers 1513, the first lifting mechanism 1515 will drive the second mounting base 1512 to reset, thereby driving the third grinding rollers 1514 to reset to prepare for grinding the next tile.

[0036] Preferably, a first avoidance notch 1516 is provided on one side of the first mounting base 1511 close to the second conveying mechanism 12;

[0037] By providing the first avoidance notch 1516 on one side of the first mounting base 1511 close to the second conveying mechanism 12, a part of the edge of the tile surface can enter between the second grinding rollers 1513 and the third grinding rollers 1514 for grinding under the conveying of the second conveying mechanism 12, and it will not affect the movement of the tiles.

[0038] More preferably, the second grinding assembly 152 includes a third mounting seat 1521, a fourth mounting seat 1522, a plurality of fourth grinding rollers 1523, and a plurality of fifth grinding rollers 1524. The third mounting seat 1521 is connected to the frame 1. The third mounting seat 1521 is provided with a second lifting mechanism 1525. The fourth mounting seat 1522 is connected to the power output end of the second lifting mechanism 1525. The fourth grinding rollers 1523 are arranged at intervals on the third mounting seat 1521 along the direction in which the second conveying mechanism 12 conveys the tiles. The top of the fourth grinding rollers 1523 is on the same horizontal plane as the conveying plane of the second conveying mechanism 12. The fifth grinding rollers 1524 are arranged at intervals on the fourth mounting seat 1522 along the direction in which the second conveying mechanism 12 conveys the tiles. The fifth grinding rollers 1524 are located above the fourth grinding rollers 1523;

[0039] The second lifting mechanism 1525 is used to drive the fourth mounting seat 1522 to descend so that the fifth grinding rollers 1524 are in contact with the upper surface of the tiles on the second conveying mechanism 12.

[0040] The working principle of the second grinding assembly 152 is the same as that of the first grinding assembly 151, so no further description will be given here.

[0041] More preferably, a second avoidance notch 1526 is provided on one side of the third mounting seat 1521 close to the second conveying mechanism 12;

[0042] The working principle of the second avoidance notch 1526 is the same as that of the first avoidance notch 1516, so no further description will be given here.

[0043] In this embodiment, the frame 1 is further provided with a collection box 16. The collection box 16 is located below the second fixing frame 141. During grinding, since the first grinding rollers 144 are arranged at intervals on the mounting frame 143, the powder after grinding the tiles will fall into the collection box 16 from the gaps between the first grinding rollers 144, and the collection box 16 can collect this powder.
