Description

Technical Field

[0001] The invention relates to the technical field of tile edge grinding, in particular to a tile edge grinding production line and a tile edge grinding method. Background Art

[0002] The manufacturing process of ceramic tiles generally includes material selection, batching, ball milling, powder spraying and granulation, pressing and molding, green body drying, printing, kiln firing, polishing and edging, grading and packaging.

[0003] Usually in the edging process after firing in the kiln, various edging machines are used to grind the edges of the tiles. For example, a single-sided edging machine can be used to grind the edges of the tiles.

[0004] In order to stabilize the tiles during the grinding process, this type of single-edge grinding machine is usually equipped with a pressure wheel and side ribs.

[0005] During the grinding process, the tiles are pressed against the side ribs by the grinding wheel, and the pressure wheel ensures the stable movement of the tiles.

[0006] In order to adapt to tiles of different widths, the side ribs and the pressure wheel are generally set to an adjustable position. The adjustment in the prior art is generally manual adjustment, that is, the position of the pressure wheel and the side rib is manually adjusted according to the size of the tile. However, this adjustment method is inconvenient.

[0007] Chinese utility model patent CN213889388U discloses an offset edge grinding machine, which mentions how to adjust the position of the side ribs, but it also fails to solve how to synchronously adjust the position of the side ribs and the pressure wheel. Summary of the Invention

[0008] In view of the deficiencies of the prior art, the present invention provides a ceramic tile edging production line and a ceramic tile edging method, which solve the problem of how to synchronously adjust the positions of the side ribs and the pressure wheel.

[0009] To achieve the above objectives, the present invention is implemented through the following technical solutions: a tile edge grinding production line, comprising:

[0010] A conveyor line, wherein the conveyor line is provided with a grinding head, a first pressing wheel, a second pressing wheel and a side rib in sequence along the width direction, wherein the grinding head is located on one side of the conveyor line, the first pressing wheel and the second pressing wheel are located above the conveyor line, and the side rib is located on the upper surface of the conveyor line;

[0011] The positioning shaft is located above the conveyor line and is used to control the simultaneous movement of the first and second pressing wheels and the side ribs in the width direction of the conveyor line at a ratio of 1:2:3, so that the position of the side ribs is adjusted to block the tiles so that the first and second pressing wheels are located on the third dividing line of the tiles;

[0012] The utility model also includes a lifting assembly, which is arranged above the second pressing wheel and is used to lift the second pressing wheel to an area away from the tiles when the second pressing wheel is too close to the first pressing wheel.

[0014] The axial direction of the positioning shaft is parallel to the width direction of the conveyor line. Positioning shafts are provided above the pressure rollers 1, 2 and the side ribs. The positioning shafts are provided with spiral grooves. The movable slider is located in the spiral grooves. The arcs of the three spiral grooves are such that when the positioning shaft rotates, the pressure rollers 1, 2 and the side ribs can be controlled to move simultaneously at a distance of 1:2:3 in the width direction of the conveyor line.

[0015] A lifting rod is provided on the moving block above the pressing wheel 2, and the lifting assembly is used to lift the pressing wheel 2 to an area away from the tiles through the lifting rod when the pressing wheel 2 is too close to the pressing wheel 1.

[0016] Furthermore, the lifting assembly includes a slope lifting plate 1 and an auxiliary lifting slope plate;

[0017] The slope lifting plate is arranged on the moving block above the side rib;

[0018] An auxiliary rod is also provided on the other side of the movable block above the second pressure wheel. The auxiliary lifting slope is located on the side close to the grinding head and is used to assist in lifting the auxiliary rod when the first slope lifting plate lifts the lifting rod.

[0019] Furthermore, the lifting assembly includes a track structure consisting of a horizontal rail 1, an inclined rail and a horizontal rail 2;

[0020] The lifting rod moves in the track structure and can lift the pressing wheel 2 to an area away from the tiles when it reaches the inclined rail.

[0021] Furthermore, the adjustment shaft above the pressure wheel 1 is the rotating shaft 1, and the end of the rotating shaft 1 close to the grinding head is also provided with a deceleration spiral groove, which is used to reduce the horizontal movement speed of the pressure wheel 1 after the pressure wheel 2 is lifted, so as to prevent the pressure wheel 1 from hitting the grinding head;

[0022] The adjustment shaft above the pressing wheel 2 is the rotating shaft 2. A ring groove is provided on the side of the rotating shaft 2 close to the grinding head, which is used to stop the horizontal movement of the pressing wheel 2 after the pressing wheel 2 is lifted.

[0023] Furthermore, the second rotating shaft is provided with a second spiral groove, and the second moving block includes:

[0024] A carrier box is provided with a lifting block, and slopes are provided near the lower portion of both sides of the lifting block, and the lifting rod is fixed on one side of the lifting block;

[0025] Slider 2, which serves as a movable slider and is fixed on both sides of the carrier box;

[0026] Spring 1, wherein the spring 1 is fixed between the slope and the bottom surface of the carrier box.

[0027] Furthermore, the pressure wheel 1 is mounted on the wheel frame 1, the moving block of the pressure wheel 1 is the moving block 1, a height adjustment cylinder is installed in the moving block 1, the lower end of the piston rod of the height adjustment cylinder is fixedly connected to the wheel frame 1, a slider 1 is provided on both sides of the moving block 1, the adjustment shaft of the pressure wheel 1 is the rotating shaft 1, and the rotating shaft 1 is provided with a spiral groove 1 adapted to the slider 1;

[0028] Both ends of the wheel frame 1 are provided with a pressure frame, and the end of the wheel frame 1 close to the pressure wheel 1 has a recess;

[0029] The top of the pressure wheel 2 is connected to the wheel frame 2, and a compensation rod is provided between the wheel frame 2 and the lifting block. Both ends of the wheel frame 2 have convex parts, and the upper surface of the convex part is provided with a T-shaped block. The lower surface of the pressure frame is provided with a T-shaped slot adapted to the T-shaped block, so that when the wheel frame 1 moves up and down, it can drive the pressure frame and the compensation rod to move vertically on the lifting block;

[0030] When the second pressing wheel is too close to the first pressing wheel, the convex portion reaches the concave portion, which is used to prevent the pressing frame from restricting the rise of the second pressing wheel.

[0031] Furthermore, it also includes a pressing plate, which is located on the horizontal moving path of the moving block 2 and is used to limit the height of the lifting block when the pressing wheel 2 is not too close to the pressing wheel 1;

[0032] The pressing plate avoids the lifting path of the lifting block.

[0033] Furthermore, it also includes a driving assembly, which includes a servo motor for driving any adjustment axis and a gear for transmission.

[0034] A tile edging method for the above-mentioned tile edging production line is applicable to the above-mentioned tile edging production line, comprising the following steps:

[0035] Step 1: According to the width of the tile, the drive assembly controls the adjustment shaft to work so that the side ribs are against the edge of the tile and due to the movement of each adjustment shaft, the pressing wheel 1 and the pressing wheel 2 are located on the third bisecting line of the tile; or

[0036] Since the width of the tile is too small, the pressing wheel 2 is lifted to an area away from the tile by the action of the lifting assembly;

[0037] Step 2: The conveyor line transports the tiles to the area of ​​the grinding head and is wet-grinded by the grinding head;

[0038] Step 3: Remove the tiles after edge grinding.

[0039] The present invention has the following beneficial effects:

[0040] (1) The tile edge grinding production line and the tile edge grinding method are characterized by providing an adjustment shaft and a spiral groove on the adjustment shaft so that the rotating adjustment shaft can synchronously drive two sets of pressure wheels and a set of side retaining edges to move, and when the side retaining edges are blocked on the tiles, the two sets of pressure wheels are distributed on the trisection line of the tiles.

[0041] (2) The tile edge grinding production line and the tile edge grinding method are provided with a lifting component so that when the pressing wheels are adapted to smaller tiles, one of the pressing wheels can be automatically lifted, thereby using only one of the pressing wheels.

DETAILED DESCRIPTION

[0062] according to Figures 1-18 The present invention describes a ceramic tile edge grinding production line and a ceramic tile edge grinding method provided by embodiments of the present invention.

[0063] In one aspect, the present invention provides a ceramic tile edging production line.

[0064] Example 1: Please refer to Figure 1-Figure 3 An embodiment of the present invention provides a tile edging production line, including a base 10, a conveyor line 12 is installed above the base 10, and a fuselage 2 is provided on one side above the base 10, and a feed baffle 1 is provided on the side of the feed end of the conveyor line 12 close to the fuselage 2.

[0065] Reference Figure 1-Figure 3 As shown, the conveyor line 12 is provided with a grinding head 9, a pressure wheel 1 41, a pressure wheel 2 42 and a side rib 3 in sequence along the width direction, wherein the grinding head 9 is located on one side of the conveyor line 12 and is assembled on the base 10. Specifically, the grinding wheel is driven to rotate by a motor, and the edge of the ceramic can be ground when the grinding wheel rotates. The grinding head 9 here can be set to any one or a combination of a horizontal grinding head, a chamfering grinding head, and a chamfered arc grinding head.

[0066] Combine Figure 3-Figure 7 As shown, the above-mentioned pressure wheel 1 41 and pressure wheel 2 42 are located above the conveyor line 12. The two sets of pressure wheels can press down on the upper surface of the tile 100, thereby providing a certain pressure thereon and playing a guiding and positioning role; and the side guard 3 is located on the upper surface of the conveyor line 12, which is used to limit the tile 100 to prevent the tile 100 from separating from the grinding head 9.

[0067] Since the width of each batch of processed tiles 100 is different, it is necessary to adjust the position of the side guard 3 so that the side guard 3 can block the edge of the tile 100 and limit it. Therefore, a positioning axis is set. The positioning axis is located above the conveyor line 12. In essence, a mechanical room 19 is set above the side of the machine body 2 close to the conveyor line 12, and the positioning axis is assembled in the mechanical room 19. The positioning axis is rotatable and is used to adjust the position of the side guard 3. When adjusting the position of the side guard 3, the position of the pressure wheel 1 41 and the pressure wheel 2 42 can also be adjusted so that the three components of the pressure wheel 1 41, the pressure wheel 2 42 and the side guard 3 move simultaneously in the width direction of the conveyor line 12 with a moving distance of 1:2:3. When adjusting in this way, only one adjustment is needed to achieve the synchronous adjustment of the pressure wheel 1 41, the pressure wheel 2 42 and the side guard 3, and the position of the side guard 3 is adjusted to block the tile 100 so that the pressure wheel 1 41 and the pressure wheel 2 42 are located on the trisection line of the tile 100.

[0068] Reference Figure 8 For better understanding, the tile 100 has two trisection lines a, and the distances from the grinding head 9 to the pressing wheel 1 41 , the distance from the pressing wheel 1 41 to the pressing wheel 2 42 , and the distance from the pressing wheel 2 42 to the side rib 3 are all equal, namely L.

[0069] However, in actual operation, another situation may occur, that is, if the width of the tile 100 is too small to accommodate the width of the two pressing wheels, then the pressing wheel 1 41 and the pressing wheel 2 42 can no longer be located on the trisection line, and the pressing wheel 2 42 needs to be lifted, that is, the pressing wheel 2 42 is no longer used, and only the pressing wheel 1 41 is used for guiding. For this purpose, a lifting component is provided here, which is provided above the pressing wheel 2 42 and is used to lift the pressing wheel 2 42 to an area away from the tile 100 when the pressing wheel 2 42 is too close to the pressing wheel 1 41, thereby achieving the purpose of using only the pressing wheel 1 41 to work.

[0070] It should be noted that the “too close” mentioned here refers to the situation where the tile 100 is too small to accommodate two sets of pressing wheels.

[0071] Reference Figure 9 It can be better understood that the tile 100 is too narrow to accommodate two sets of pressure wheels at this time, and then the pressure wheel 2 42 needs to be lifted to a certain height before the side retaining edge 3 continues the blocking operation, that is, when the pressure wheel 2 42 reaches the position of node b, the lifting assembly lifts the pressure wheel 2 42.

[0072] Combine Figure 7 、 Figure 10-12 As shown, moving blocks are provided above the above-mentioned pressure roller 1 41, pressure roller 2 42 and side rib 3, and moving sliders are provided on both sides of the moving block. The axial direction of the positioning shaft is parallel to the width direction of the conveyor line 12, and positioning shafts are provided above the pressure roller 1 41, pressure roller 2 42 and side rib 3. A spiral groove is provided on the positioning shaft, and the moving slider is located in the spiral groove. When the positioning shaft rotates, it can push the moving slider to produce axial displacement through the action of the spiral groove, thereby adjusting the position of the pressure roller 1 41, pressure roller 2 42 and side rib 3. It should be noted that the curvature of the three spiral grooves is an curvature that can control the pressure roller 1 41, pressure roller 2 42 and side rib 3 to move simultaneously at a distance of 1:2:3 in the width direction of the conveyor line 12 when the positioning shaft rotates.

[0073] The adjustment shaft, spiral groove, moving block and moving slider of the above-mentioned pressing wheel 41 are respectively: rotating shaft 51, spiral groove 511, moving block 11 and slider 111 (such as Figure 10 ).

[0074] The adjustment shaft, spiral groove, moving block and moving slider of the above-mentioned pressing wheel 2 42 are respectively: the rotating shaft 2 52, the spiral groove 2 521, the moving block 2 6 and the slider 2 62 (as shown in FIG. Figure 11 ), the end of the spiral groove 2 521 is located in the area of ​​node b, which is set here as the closest area where the pressure wheel 2 42 can approach the pressure wheel 1 41.

[0075] The positioning shaft, spiral groove, moving block and moving slider of the side rib 3 are respectively: the rotating shaft 3 53, the spiral groove 3 531, the moving block 3 16 and the slider 3 161 (as shown in FIG. Figure 12 ).

[0076] Preferably, a guide rod 14 is provided in the machine room 19 for horizontally guiding the moving block.

[0077] Specifically, in order to achieve the above-mentioned situation where the tile 100 is too narrow ( Figure 9In the state shown), the pressing wheel 2 42 can be automatically lifted, a lifting rod 66 is provided on the moving block 2 6, and a slope lifting plate 15 is provided on the moving block 3 16 above the side guard 3. The slope lifting plate 15 is used to lift the pressing wheel 2 42 to an area away from the tile 100 by lifting the lifting rod 66 when the pressing wheel 2 42 is too close to the pressing wheel 1 41. Figure 9 In the state shown, the slope lifting plate 15 above the side rib 3 just reaches the position of the lifting rod 66 and lifts it up.

[0078] Specifically, in order to achieve the purpose of the above-mentioned moving block 2 6 being able to drive the pressing wheel 2 42 to move horizontally and vertically, the structure of the moving block 2 6 is described in detail below. Figure 13-16 As shown, the second moving block 6 includes a carrier box 61, a second slider 62 and a first spring 65.

[0079] The carrier box 61 has a lifting block 63 in its interior, a Z-axis slider 632 on the side of the lifting block 63, and a Z-axis slide groove adapted thereto is provided on the inner wall of the carrier box 61. A lifting rod 66 is fixed on one side of the lifting block 63. Figure 14 、 Figure 15 and Figure 18 In the state shown, the lifting block 63 is at the lowest position, and it does not lift the pressing wheel 2 42 upward. When the slope lifting plate 15 moves with the moving block 3 16 to Figure 9 When the middle side retaining edge 3 is in position, the slope lifting plate 15 can push the lifting rod 66 upward, so that the lifting rod 66 lifts the entire lifting block 63 upward along the carrier box 61, and then the lifting block 63 can drive the lower wheel frame 2 421 to move upward, so that the pressure wheel 2 42 will move upward and away from the tile 100.

[0080] Preferably, slopes 631 are provided in the areas near the lower portion of both sides of the lifting block 63, and a spring 1 65 is fixed between the slope 631 and the bottom surface of the carrier box 61. When the lifting block 63 is lifted by the lifting assembly, the spring 1 65 is in a stretched state. When the lifting block 63 is no longer lifted, the spring 1 65 can rebound, thereby lowering the height of the lifting block 63 so that the height of the lifting block 63 can be reset.

[0081] The second slider 62 is fixed on both sides of the carrier box 61 , so when the second shaft 52 rotates, the second slider 62 can be pushed to move through the second spiral groove 521 , thereby realizing the movement of the entire moving block 2 6 .

[0082] In order to ensure that after the lifting block 63 is lifted (that is, after the moving block 2 6 passes the node b and the pressure wheel 2 42 has been lifted), the entire moving block 2 6 no longer continues to approach the pressure wheel 1 41 as the adjustment shaft rotates (this is because the pressure wheel 2 42 itself has a certain thickness, and its continued approach to the pressure wheel 1 41 will cause it to collide with the pressure wheel 1 41), an annular groove 522 is provided on the side of the rotating shaft 2 52 close to the grinding head 9, that is, the slider 2 62 passes the end of the spiral groove 2 521 and enters the annular groove 522, so that the pressure wheel 2 42 stops moving horizontally after being lifted and no longer approaches the pressure wheel 1 41.

[0083] It should be noted that, after the above lifting process is completed, in order to prevent the pressing wheel 1 41 from continuously moving rapidly to the left ( Figure 9 In order to prevent the grinding head 9 from being hit by the side guard 3 (as shown in the perspective shown), a deceleration spiral groove 512 is provided at the end of the rotating shaft 51 near the grinding head 9. When the slider 111 enters the deceleration spiral groove 512 from the spiral groove 511, the deceleration spiral groove 512 can reduce the horizontal movement speed of the slider 111, thereby reducing the movement speed of the pressure wheel 41, thereby ensuring that when the side guard 3 blocks the edge of the tile 100, the pressure wheel 41 will not hit the grinding head 9, that is, time is reserved for the side guard 3 to move to the edge of the tile 100.

[0084] In fact, in actual operation, in addition to adjusting the horizontal position of the two sets of pressing wheels, you also need to adjust their vertical height. In order to adjust the vertical height of the two sets of pressing wheels, refer to Figure 10 As shown, the above-mentioned pressure wheel 41 is installed on the wheel frame 411, and a height adjustment cylinder 13 is installed in the moving block 11. The lower end of the piston rod of the height adjustment cylinder 13 is fixedly connected to the wheel frame 411, so that the pressure wheel 41 and the wheel frame 411 can be lifted and lowered by the extension and retraction of the height adjustment cylinder 13.

[0085] Combine Figure 6 、 Figure 7 、 Figure 10 and Figure 11 As shown, in order to achieve the synchronous lifting and lowering of the pressure wheel 2 42 and the pressure wheel 1 41 during height adjustment, a pressure frame 412 is provided at both ends of the wheel frame 1 411, and a compensation rod 64 is provided between the wheel frame 2 421 and the lifting block 63. A reset spring 641 is provided on the outside of the compensation rod 64, and the upper end of the reset spring 641 is fixed to the inside of the lifting block 63. The reset spring 641 applies a downward rebound force to the compensation rod 64. Both ends of the wheel frame 2 421 have a convex portion 422, and the upper surface of the convex portion 422 is provided with a T-shaped block 423, and the lower surface of the pressure frame 412 is provided with a T-shaped slide groove adapted to the T-shaped block 423.

[0086] In this embodiment, when the width of the tile 100 is large, for example Figure 8In the state shown, the protrusion 422 is located below the pressure frame 412, so that the lifting of the pressure frame 412 can drive the entire protrusion 422 to lift, so that when the wheel frame 411 moves up and down, it can drive the pressure frame 412 and the compensation rod 64 to move vertically on the lifting block 63.

[0087] In addition, combined Figure 6 、 Figure 7 、 Figure 10 、 Figure 11 and Figure 17 As shown, it should also be noted that in order to ensure that the pressing frame 412 does not block the convex portion 422 when the pressing wheel 2 42 is lifted, a concave portion 413 is provided at one end of the wheel frame 1 411 close to the pressing wheel 1 41. Figure 9 In the state shown, when the second pressing wheel 42 moves to the position of node b, the convex portion 422 actually moves to the area of ​​the concave portion 413, so that when the second pressing wheel 42 is lifted upward, the pressing frame 412 will not block the convex portion 422 from moving upward.

[0088] It should be noted that in order to avoid the situation where the entire lifting block 63 moves upward due to the large sliding friction between the compensation rod 64 and the lifting block 63 during the height adjustment of the pressure wheel, a pressure plate 8 is provided here. The pressure plate 8 is located on the horizontal moving path of the moving block 2 6 and is used to limit the height of the lifting block 63 when the pressure wheel 2 42 is not too close to the pressure wheel 1 41, to prevent the lifting block 63 from moving upward autonomously, and the pressure plate 8 avoids the lifting path of the lifting block 63 to prevent the pressure plate 8 from blocking the lifting block 63 from moving upward.

[0089] like Figure 3 and Figure 5 As shown, in order to ensure that the lifting block 63 can be more stable during the lifting stage, an auxiliary lifting ramp 17 is also provided here. An auxiliary rod 67 is installed on the side of the lifting block 63 away from the lifting rod 66. The auxiliary lifting ramp 17 is located on the side close to the grinding head 9, and is used to assist in lifting the auxiliary rod 67 when the slope lifting plate 15 lifts the lifting rod 66, so that both sides of the lifting block 63 are subjected to lifting force to ensure its stable lifting.

[0090] Combine Figure 3 and Figure 5 As shown, it also includes a driving component, which includes a servo motor 7 for driving any adjustment axis and gears for transmission. How to use gears to drive each adjustment axis is a well-known technology and will not be described here in detail.

[0091] When in use (working):

[0092] First, you need to first adjust the position of each component. There are two specific adjustments. One is as follows: Figure 8 The wider tile 100 shown, another is as Figure 9 Narrower tile 100 is shown.

[0093] When the tile is 100 wider:

[0094] S1. When the conveyor line 12 is stopped, press the reset button on the height adjustment cylinder 13 to adjust the heights of the pressing wheel 1 41 and the pressing wheel 2 42 to the initial height. At the initial height, the reset spring 641 on the pressing wheel 2 42 is in a natural state.

[0095] S2. Adjust the horizontal position of the side guard 3 and each group of pressure wheels: drive the servo motor 7 to work according to the width of the tile 100 to be polished. When the servo motor 7 is working, the rotating shaft 1 51, the rotating shaft 2 52, and the rotating shaft 3 53 rotate synchronously. When the rotating shaft 1 51 rotates, the spiral groove 1 511 and the slider 1 111 push the moving block 11 to gradually move toward the direction of the polishing head 9, that is, the pressure wheel 1 41 gradually moves toward the direction of the polishing head 9; when the rotating shaft 2 52 rotates, the spiral groove 2 521 and the slider 2 62 push the entire moving block 11 to gradually move toward the polishing head 9. The movable block 2 6 gradually moves toward the grinding head 9, that is, the pressure wheel 2 42 moves toward the grinding head 9; when the rotating shaft 3 53 rotates, the spiral groove 3 531 and the slider 3 161 push the movable block 3 16 to gradually move toward the grinding head 9, so that the side rib 3 gradually approaches the tile 100; the moving distance ratio of the pressure wheel 1 41, the pressure wheel 2 42 and the side rib 3 is 1:2:3, so that when the side rib 3 is pressed on the edge of the tile 100, the pressure wheel 1 41 and the pressure wheel 2 42 are located on the trisection line of the tile 100;

[0096] S3. By controlling the extension of the height adjustment cylinder 13, the height of the two sets of pressure wheels is adjusted so that the height of the two sets of pressure wheels can adapt to the thickness of the tile 100: the height adjustment cylinder 13 is extended to push the wheel frame 1 411 to move downward, so that the pressure wheel 1 41 can be pressed on the upper surface of the tile 100. At the same time, when the wheel frame 1 411 moves downward, the convex portion 422 can be pressed down by the pressure frame 412, so that the entire wheel frame 2 421 can move downward synchronously. The downward movement of the wheel frame 2 421 allows the pressure wheel 2 42 to also press down on the upper surface of the tile 100. At this time, the pressure wheels 1 41 and 42 are located on the trisection line of the tile 100, and then the two sets of pressure wheels produce uniform pressure on the tile 100, and the guiding effect is good.

[0097] When tile 100 is narrower:

[0098] S1, the adjustment process is the same as that of S1 above;

[0099] S2 is basically the same as the adjustment process of S2 above, except that when the second pressure wheel 42 reaches the b node, the convex portion 422 reaches the position of the concave portion 413, and the pressure frame 412 no longer applies pressure to the convex portion 422. At the same time, the slope lifting plate 15 can push the lifting rod 66 upward, so that the entire lifting block 63 can move upward. When the lifting block 63 moves upward, the entire pressure wheel 2 42 and the wheel frame 2 421 can be driven upward by the compensation rod 64 below, forming a state in which the pressure wheel 2 42 is separated from the tile 100 upward, and the pressure wheel 2 4 After upwardly separating from the tile 100, the slider 2 62 enters the annular groove 522 from the spiral groove 2 521. Due to the limiting effect of the annular groove 522, the slider 2 62 no longer moves with the rotation of the shaft 2 52, that is, the pressure wheel 2 42 stops moving. At the same time as the slider 2 62 enters the annular groove 522 from the spiral groove 2 521, the slider 1 111 enters the interior of the deceleration spiral groove 512. At this time, the horizontal movement speed of the pressure wheel 1 41 decreases, and the side rib 3 continues to approach the tile 100 with the rotation of the shaft 3 53 until it is pressed on the side of the tile 100.

[0100] Second, start the conveyor line 12 so that the conveyor line 12 begins to convey the ceramic tile 100, and the ceramic tile 100 is polished when passing through the polishing head 9.

[0101] 3. Before grinding the next batch of tiles 100, first reset the height adjustment cylinder 13, then press the reset button of the servo motor 7 to rotate each adjustment shaft and reset each adjustment shaft to the state at node b. At this time, the recess 413 is aligned with the protrusion 422, so that as each moving block moves, the lifting rod 66 loses the lifting of the slope lifting plate 15 and the entire lifting block 63 drives the entire pressure wheel 2 42 downward through the compensation rod 64. At this time, the protrusion 422 passes downward through the recess 413. As the adjustment shaft rotates, the T-shaped block 423 of the protrusion 422 is stuck in the T-shaped slot and slides in the T-shaped slot until it is restored to the farthest distance between the side guard 3 and the grinding head 9.

[0102] Example 2: Figure 18 The difference between this embodiment and the first embodiment is that the lifting assembly includes a track structure consisting of a horizontal rail 181, an inclined rail 182 and a horizontal rail 2 183; the lifting rod 66 moves within the track structure, and when it reaches the inclined rail 182, it can lift the pressure wheel 2 42 to an area away from the tile 100.

[0103] On the other hand, the present invention also provides a method for grinding ceramic tile edges, which is applicable to the above ceramic tile grinding production line and comprises the following steps:

[0104] Step 1: According to the width of the tile 100, the driving assembly controls the adjustment shaft to work so that the side rib 3 is close to the edge of the tile and the action of each adjustment shaft causes the first pressing wheel 41 and the second pressing wheel 42 to be located on the trisection line of the tile 100; or

[0105] Since the width of the tile 100 is too small, the pressing wheel 2 42 is lifted to an area away from the tile 100 by the action of the lifting assembly;

[0106] Step 2: The conveyor line 12 conveys the tile 100 to the area of ​​the grinding head 9 and is wet-grinded by the grinding head 9;

[0107] Step 3: Remove the edge-grinded tiles 100.
