Description

Technical Field

[0001] This invention relates to the field of polishing equipment technology, and in particular to a device for polishing the edges and corners of ceramic tiles. Background Technology

[0002] Round ceramic tiles are a common tile size on the market. When grinding the edges and corners of round ceramic tiles, a vacuum suction cup is typically used to coaxially fix the tile onto a rotating shaft. Then, a grinding disc positioned on one side of the tile rotates circumferentially to grind the edges and corners. Simultaneously, a feed mechanism controls the grinding disc to advance radially along one end of the tile. For example, for every revolution of the tile, the feed mechanism advances the grinding disc by one millimeter. This process creates the desired bevel at the corner of the round tile. (See reference...) The Chinese utility model patent with authorization announcement number CN221833986U discloses a ceramic tile edge polishing device. However, since ceramic tiles are made by mixing clay, quartz sand, feldspar and gas additives and firing them at high temperature, their texture is not very uniform. During the polishing process of the polishing disc polishing the edges of the ceramic tile, it is inevitable to encounter sand and gravel protrusions. At this time, the positive pressure between the polishing disc and the sand and gravel protrusions increases sharply, and the polishing disc is severely worn in some areas. This can easily cause spot-like unevenness on the polished surface of the ceramic tile, which greatly affects the appearance quality. Summary of the Invention

[0003] Therefore, it is necessary to provide a tile edge grinding device to address the problems existing in current grinding devices, so as to solve the problem that the edge grinding surface of tiles is prone to spot-like unevenness, which affects the appearance quality.

[0004] The above objectives are achieved through the following technical solutions:

[0005] A tile edge grinding device includes:

[0006] The frame includes a base, a support section and a sliding section. There are two support sections and two sliding sections. The two support sections are arranged vertically on the base. The two sliding sections correspond one-to-one with the two support sections and are elastically connected. The sliding sections can slide relative to the support sections in the front-back direction.

[0007] A suction assembly, located at the front of the base, is used to hold the tile and allow the tile to rotate about its axis.

[0008] There are two grinding cones, coaxial and spaced apart, and rotatably mounted on corresponding sliding parts, with the small ends of the two grinding cones facing each other.

[0009] The middle drive ring is coaxial with the grinding cone and both ends are rotatably connected to the grinding cone. The outer diameter of the middle drive ring is matched with the small end diameter of the grinding cone.

[0010] The first drive assembly is used to drive the grinding cone to rotate circumferentially.

[0011] The second drive component is used to drive the intermediate drive ring to rotate circumferentially.

[0012] Preferably, the vertical distance between the two support portions is adjustable.

[0013] Preferably, the first drive assembly includes an upper first motor, a lower first motor, a first rotating sleeve, and a second rotating sleeve. The upper first motor is disposed on the upper sliding part, with its output shaft facing downwards. The upper end of the first rotating sleeve is fixedly connected to the output shaft of the upper first motor, and the lower end of the first rotating sleeve is coaxially fixedly connected to the upper grinding cone. The lower first motor is disposed on the lower sliding part, with its output shaft facing upwards. The lower end of the second rotating sleeve is fixedly connected to the output shaft of the lower first motor, and the upper end of the second rotating sleeve is coaxially fixedly connected to the lower grinding cone.

[0014] Preferably, the second drive assembly includes a second motor, a rotating shaft, and a friction disc. The second motor is mounted on the upper sliding part with its output end facing downwards. The rotating shaft is fixedly connected to the output shaft of the second motor. The friction disc is coaxially mounted outside the rotating shaft and undergoes frictional transmission with the intermediate drive ring.

[0015] Preferably, the support portion is movable relative to the base in the front-rear direction.

[0016] Preferably, it also includes a third drive assembly for driving the support to move relative to the base in the front-rear direction.

[0017] Preferably, the third drive assembly includes a third motor, a screw, and a transverse connecting rod. The third motor is located at the rear end of the base, and the output shaft of the third motor is fixedly connected to the screw. The transverse connecting rod is arranged transversely, with its middle part threadedly connected to the screw, and its two ends connected to two support parts respectively.

[0018] Preferably, the intermediate drive ring includes a male drive ring and a female drive ring, which are coaxial from top to bottom and are inserted into each other at one end. The other end of the male drive ring is sleeved with the first rotating sleeve, and the male drive ring and the first rotating sleeve can move synchronously and rotate relative to each other. The other end of the female drive ring is sleeved with the second rotating sleeve, and the female drive ring and the second rotating sleeve can move synchronously and rotate relative to each other.

[0019] Preferably, the interlocking areas of the male drive ring and the female drive ring have gaps.

[0020] Preferably, the suction assembly includes a first linear drive source, a connecting support, and a vacuum suction cup. The fixed end of the first linear drive source is located at the front of the base, the connecting support is connected to the telescopic end of the first linear drive source, and the vacuum suction cup is rotatably connected to the connecting support.

[0021] The beneficial effects of this invention are:

[0022] This invention comprises a frame, a grinding cone, and an intermediate drive ring. During the grinding of the chamfered surface of a tile, whenever the grinding cone contacts a sand-like protrusion on the chamfered surface, the protrusion pushes the grinding cone backward, causing the intermediate drive ring to be suspended. The grinding cone then drives the tile to rotate in the opposite direction until the sand-like protrusion no longer pushes the grinding cone backward. At this point, the intermediate drive ring contacts the outer circumference of the tile again and drives the tile to continue rotating in the forward direction. The grinding cone then approaches the sand-like protrusion again to grind it until it is removed from the chamfered surface. Only then does the intermediate drive ring drive the tile to continue rotating, allowing the grinding cone to pass the previous position of the sand-like protrusion. This avoids severe wear on the grinding cone due to the squeezing action of the sand-like protrusion and helps prevent spot-like unevenness on the ground surface of the tile, thus improving the appearance quality of the ground surface.

[0045] Tiles are mainly made from natural raw materials, and no harmful components such as formaldehyde or heavy metals are added during the production process, which conforms to the concept of a healthy and sustainable lifestyle. In addition, tiles have the advantages of being easy to clean, moisture-proof and mildew-proof, aesthetically pleasing and diverse, and cost-effective. Therefore, tiles are widely used in furniture such as dining tables and coffee tables. As tabletops for dining tables and coffee tables, which are frequently used pieces of furniture, users inevitably touch the edges with their arms or rub their legs against the corners when standing up. Therefore, during the processing of tiles used as tabletops, the edges and corners of the tiles need to be polished to form smooth bevels.

[0046] like Figures 1 to 9As shown, a tile edge-grinding device includes a frame 100, a holding assembly 200, a grinding cone 300, an intermediate drive ring 400, a first drive assembly 500, and a second drive assembly 600. The frame 100 includes a base 110, a support portion 120, and a sliding portion 130. There are two support portions 120 and two sliding portions 130. The two support portions 120 are spaced vertically on the base 110. The two sliding portions 130 correspond one-to-one with the two support portions 120 and are elastically connected. The sliding portions 130 can slide relative to the support portions 120 in the front-back direction. Specifically, the front end of the support portion 120 has a guide groove, and the rear end of the sliding portion 130 is slidably connected in the guide groove. The rear end of the sliding portion 130 is fixedly connected to the bottom of the support portion 120 by a spring 140. The holding assembly 200 is located at the front of the base 110 and is used to fix the tile 900 and allow the tile 900 to rotate around its axis. There are two grinding cones 300, which are coaxial and spaced apart vertically. The two grinding cones 300 are rotatably mounted on corresponding sliding parts 130, and their small ends face each other. A middle drive ring 400 is coaxial with the grinding cones 300 and its two ends are rotatably connected to the two grinding cones 300 respectively. The outer diameter of the middle drive ring 400 is adapted to the diameter of the small end of the grinding cones 300. The middle drive ring 400 is configured such that when both the middle drive ring 400 and the grinding cones 300 are in contact with the tile 900, the friction between the middle drive ring 400 and the tile 900 is greater than the friction between the grinding cones 300 and the tile 900. The first drive assembly 500 is used to drive the grinding cones 300 to rotate circumferentially, and the second drive assembly 600 is used to drive the middle drive ring 400 to rotate circumferentially. The direction of the circumferential rotation of the middle drive ring 400 is opposite to the direction of the circumferential rotation of the grinding cones 300.

[0047] When grinding the edges of tile 900, the worker first pushes the two sliding parts 130 backwards synchronously until the grinding cone 300 no longer interferes with the installation position of tile 900. At this point, the spring 140 is compressed. Next, tile 900 is held on the holding assembly 200, so that the axis of tile 900 coincides with the rotation axis of the holding assembly 200. At this point, under the elastic force of the spring 140, the conical outer circumference of the two grinding cones 300 elastically abuts against the two edges of tile 900. Then, the worker presses down on tile 900 to restrict its rotation. Finally, the first drive assembly 500 and the second drive assembly 600 are activated. The first drive assembly 500 drives the two grinding cones 300 to rotate synchronously. The second drive assembly 600 drives the intermediate drive ring 400 to rotate. Since the tile 900 is in elastic contact with the conical outer surfaces of the two grinding conical discs 300, the material in the contact area between the tile 900 and the grinding conical discs 300 is gradually removed under the rotation of the two grinding conical discs 300. As the material in the contact area between the tile 900 and the grinding conical discs 300 is gradually removed, the elastic force of the spring 140 is gradually released. The spring 140 pushes the sliding part 130 and the two grinding conical discs 300 to move forward gradually, keeping the grinding conical discs 300 in elastic contact with the tile 900. When the grinding conical discs 300 move forward until the outer surface of the intermediate drive ring 400 contacts the outer surface of the tile 900, the intermediate drive ring 400... Since the outer circumferential surface of tile 900 cannot be polished, the diameter of the outer circumferential surface of tile 900 will not decrease, meaning the intermediate drive ring 400 will not move forward. Therefore, the two polishing cones 300 cannot continue to move forward, and the sliding part 130 connected to the polishing cones 300 will not move forward either. At this point, a notch is cut into the upper and lower parts of one circumferential side of tile 900 by the corresponding polishing cones 300. Next, the worker stops pressing tile 900 by hand. Because the intermediate drive ring 400 is in contact with the outer circumferential surface of tile 900, and the friction between the intermediate drive ring 400 and tile 900 is greater than the friction between the polishing cones 300 and tile 900, tile 900 rotates due to the frictional drive of the intermediate drive ring 400. The 900 is rotated under force so that the two grinding cones 300 remain in contact with one side of the notch. Under the rotation of the two grinding cones 300, the material on one side of the notch of the tile 900 is gradually removed by grinding, and the length of the notch gradually increases. Since the rotation direction of the grinding cones 300 is opposite to the rotation direction of the middle drive ring 400, the grinding cones 300 rotate a longer distance relative to the tile 900 during the grinding process, which helps to speed up the grinding efficiency. During the grinding process, when the grinding cones 300 contact the abrasive protrusions on the chamfered surface of the tile 900, the abrasive protrusions push the grinding cones 300 backward. At this time, the middle drive ring 400 is in a suspended state and no longer rubs against the tile 900. Under the rotation of the grinding cones 300,Tile 900 rotates in the reverse direction at a certain angle until the abrasive protrusions on tile 900 no longer push the grinding cone 300 backward. At this point, the intermediate drive ring 400 contacts the outer circumference of tile 900 again, driving tile 900 to continue rotating forward. The grinding cone 300 then approaches the abrasive protrusions on tile 900 again to grind them. Similarly, when the abrasive protrusions push the grinding cone 300 backward again, tile 900 continues to rotate in the reverse direction at a certain angle until the abrasive protrusions on the chamfered surface of tile 900 are ground down. After the grinding process is complete, the intermediate drive ring 400 will drive the tile 900 to continue rotating, allowing the grinding cone 300 to pass over the previous abrasive protrusions. This prevents the grinding cone 300 from being severely worn due to the pressure of the abrasive protrusions, and helps avoid spot-like unevenness on the grinding bevel of the tile 900. Therefore, it improves the appearance quality of the grinding bevel of the tile 900. After the tile 900 rotates one revolution, the notch forms an annular chamfered bevel on the upper and lower parts of the tile 900. At this point, the grinding of the upper and lower edges of the tile 900 is complete.

[0048] Furthermore, to ensure that the frictional force between the intermediate drive ring 400 and the tile 900 is greater than that between the grinding conical disc 300 and the tile 900 when both the intermediate drive ring 400 and the grinding conical disc 300 are in contact with the tile 900, a layer of rubber can be applied to the outer circumferential surface of the intermediate drive ring 400 to provide a higher coefficient of friction. This ensures that the intermediate drive ring 400 can provide a greater driving force to the tile 900 after the outer circumferential surface of the tile 900 comes into contact with it. In addition, when the tile 900 is ground by the grinding conical disc 300 until the outer circumferential surface of the intermediate drive ring 400 contacts the outer circumferential surface of the tile 900, the contact area between the intermediate drive ring 400 and the tile 900 is greater than the contact area between the tile 900 and the grinding conical disc 300. This helps to ensure that the frictional force between the intermediate drive ring 400 and the tile 900 is greater than that between the grinding conical disc 300 and the tile 900.

[0049] Furthermore, to facilitate staff observation of when the intermediate drive ring 400 contacts the tile 900, such as... Figure 7As shown, a reflector 150 is provided at the lower end of the sliding part 130 and on the side near the rotating shaft 620. A distance sensor 160 is provided on the lower surface of the support part 120 and directly opposite the reflector 150. An indicator light (not shown) is provided on the base 110. The indicator light is connected to the distance sensor 160. Before the intermediate drive ring 400 contacts the outer peripheral surface of the tile 900, the grinding cone 300 continuously removes material from the grinding area of ​​the tile 900. Therefore, the distance between the reflector 150 and the distance sensor 160 is measured by the distance sensor 160. The distance between them changes over time. When the intermediate drive ring 400 comes into contact with the tile 900, the sliding part 130 no longer moves forward. That is, at this time, the distance between the reflector 150 and the distance sensor 160 no longer changes over time. That is, after a preset time, when the distance measured by the distance sensor 160 is the same as the distance measured before the preset time, it means that the intermediate drive ring 400 is in contact with the tile 900. At this time, the distance sensor 160 sends an electrical signal to the indicator light, and the indicator light is activated and lit. After the staff observes that the indicator light is lit, they can stop pressing down on the tile 900.

[0050] It should also be noted that, during the grinding of tile 900, in order to increase the grinding speed and reduce the temperature of the grinding area, grinding fluid needs to be continuously sprayed onto the location of the grinding cone 300 until the grinding of tile 900 is completed.

[0051] It is understandable that the thickness of the ceramic tile 900 varies. In order to adapt to ceramic tiles 900 of different thicknesses and increase the versatility of the device, in a further embodiment, the vertical spacing between the two support parts 120 is adjustable.

[0052] When the thickness of the tile 900 to be processed is not compatible with the vertical spacing between the two support parts 120, the spacing between the two support parts 120 needs to be adjusted so that it matches the thickness of the tile 900 to be processed. To make the vertical spacing between the two support parts 120 adjustable, further, such as... Figures 1-3 As shown, the base 110 has two studs 810 inside, spaced apart from each other. The left and right sides of the rear ends of the two support parts 120 are slidably connected to the two studs 810. Each stud 810 is threaded with four nuts 820. Two nuts 820 abut against the upper and lower end faces of the upper support part 120, and the other two nuts 820 abut against the upper and lower end faces of the lower support part 120. When it is necessary to adjust the distance between the two support parts 120, the nuts 820 are rotated to adjust their positions on the studs 810.

[0053] In a further embodiment, such as Figure 3As shown, the first drive assembly 500 includes an upper first motor 510, a lower first motor 520, a first rotating sleeve 530, and a second rotating sleeve 540. The upper first motor 510 is mounted on the upper sliding part 130, with its output shaft facing downwards. The upper end of the first rotating sleeve 530 is fixedly connected to the output shaft of the upper first motor 510, and the lower end of the first rotating sleeve 530 is coaxially fixedly connected to the upper grinding cone 300. The lower first motor 520 is mounted on the lower sliding part 130, with its output shaft facing upwards. The lower end of the second rotating sleeve 540 is fixedly connected to the output shaft of the lower first motor 520, and the upper end of the second rotating sleeve 540 is coaxially fixedly connected to the lower grinding cone 300.

[0054] When the first drive assembly 500 needs to be started, the upper first motor 510 and the lower first motor 520 are started respectively. The output shaft of the upper first motor 510 drives the first rotating sleeve 530 to rotate. Since the upper grinding cone 300 is coaxially and fixedly connected to the lower end of the first rotating sleeve 530, the first rotating sleeve 530 drives the upper grinding cone 300 to rotate. At the same time, the output shaft of the lower first motor 520 drives the second rotating sleeve 540 to rotate. Since the lower grinding cone 300 is coaxially and fixedly connected to the upper end of the second rotating sleeve 540, the second rotating sleeve 540 drives the lower grinding cone 300 to rotate.

[0055] In a further embodiment, such as Figure 3 and Figure 4 As shown, the second drive assembly 600 includes a second motor 610, a rotating shaft 620, and a friction disc 630. The second motor 610 is mounted on the upper sliding part 130 with its output end facing downwards. The rotating shaft 620 is fixedly connected to the output shaft of the second motor 610. The friction disc 630 is coaxially mounted outside the rotating shaft 620 and undergoes frictional transmission with the intermediate drive ring 400.

[0056] When the first drive assembly 500 needs to be started, the second motor 610 is started. The output shaft of the second motor 610 drives the rotating shaft 620 to rotate, and the rotating shaft 620 drives the friction disk 630 to rotate. Since the friction disk 630 and the intermediate drive ring 400 are driven by friction, the friction disk 630 drives the intermediate drive ring 400 to rotate.

[0057] To increase the versatility of the device and adapt it to the processing needs of ceramic tiles 900 of different diameters, in a further embodiment, such as Figure 3 and Figure 5 As shown, the support 120 can move relative to the base 110 in the front-back direction to ensure that the initial compression of the spring 140 is a preset value when processing ceramic tiles 900 of different diameters.

[0058] To enable the support part 120 to move relative to the base 110 in the front-back direction, the tile edge grinding device further includes a third drive assembly 700 for driving the support part 120 to move relative to the base 110 in the front-back direction. The third drive assembly 700 includes a third motor 710, a screw 720, and a transverse connecting rod 730. The third motor 710 is located at the rear end of the base 110, and the output shaft of the third motor 710 is fixedly connected to the screw 720. The transverse connecting rod 730 is arranged transversely and is threadedly connected to the screw 720 in the middle. Its two ends are respectively connected to the two support parts 120. Specifically, the two ends of the transverse connecting rod 730 are fixedly connected to two studs 810.

[0059] When the diameter of the tile 900 to be processed cannot meet the preset value of the initial compression of the spring 140, the third motor 710 is started. The output shaft of the third motor 710 drives the screw 720 to rotate. The rotation of the screw 720 drives the transverse connecting rod 730 to move along the axis of the screw 720. Then the transverse connecting rod 730 drives the two studs 810 to move synchronously. The studs 810 drive the two support parts 120 to move in the front and back direction to adjust the distance between the grinding cone 300 and the tile 900 to be processed, so that the diameter of the tile 900 to be processed can meet the same initial compression of the spring 140.

[0060] Furthermore, to facilitate the movement of the two studs 810, the upper and lower ends of the base 110 are provided with sliding grooves 111. The sliding grooves 111 extend in the front-back direction and penetrate the base 110. The two ends of the studs 810 are slidably connected in the sliding grooves 111. To prevent the studs 810 from sliding in the vertical direction, the two ends of the studs 810 are fixedly connected with limit rings 830. The diameter of the limit rings 830 is greater than the width of the sliding grooves 111.

[0061] In a further embodiment, such as Figure 4As shown, the intermediate drive ring 400 includes a male drive ring 410 and a female drive ring 420. The male drive ring 410 and the female drive ring 420 are coaxial from top to bottom and are interlocked at one end. Specifically, the lower end of the male drive ring 410 has several elongated slots evenly spaced in the circumferential direction, which extend along the axis of the male drive ring 410. The upper end of the female drive ring 420 has several matching elongated slots evenly spaced in the circumferential direction. The protruding part at the lower end of the male drive ring 410 is slidably inserted into the elongated slot at the upper end of the female drive ring 420, and the protruding part at the upper end of the female drive ring 420 is slidably inserted into the elongated slot at the lower end of the male drive ring 410. The other end of the male drive ring 410 is sleeved with the first rotating sleeve 530, and the male drive ring 410... Ring 410 and the first rotating sleeve 530 can move synchronously and rotate relative to each other. Specifically, the upper part of the male drive ring 410 is provided with an annular groove, and a bearing is provided in the annular groove. The inner ring of the bearing is fixedly connected to the annular groove wall of the male drive ring 410. A screw is threaded on one side of the first rotating sleeve 530. The axis of the screw is horizontal and the screw is inserted into the annular groove. The other end of the female drive ring 420 is sleeved with the second rotating sleeve 540. The female drive ring 420 and the second rotating sleeve 540 can move synchronously and rotate relative to each other. The connection method between the female drive ring 420 and the second rotating sleeve 540 is the same as the connection method between the male drive ring 410 and the first rotating sleeve 530, and will not be described in detail here.

[0062] When the first rotating sleeve 530 rotates, the first rotating sleeve 530 and the second rotating sleeve 540 drive the corresponding screw to rotate synchronously. Since the screw is located in the annular groove, the screw will not interfere with the relative rotation between the second rotating sleeve 540 and the male drive ring 410. The same applies to the cooperation between the second rotating sleeve 540 and the female drive ring 420, which will not be described in detail here.

[0063] When the first rotating sleeve 530 moves along its axis, the first rotating sleeve 530 drives the screw to move synchronously. Since the screw is located in the annular groove, the screw drives the male drive ring 410 to move synchronously. The same applies to the cooperation between the second rotating sleeve 540 and the female drive ring 420, which will not be described in detail here.

[0064] In a further embodiment, such as Figure 3 As shown, a gap 430 is formed in the interlocking area of ​​the male drive ring 410 and the female drive ring 420. A support ring is provided at the front of the lower support part 120. The support ring is hollow inside. The inner peripheral wall of the support ring is rotatably connected to the outer peripheral surface of the second rotating sleeve 540. A drain hole is provided on the lower outer peripheral surface of the second rotating sleeve 540, and a drain hole is also provided on the outer peripheral surface of the support ring.

[0065] This design allows some cutting fluid to enter the male drive ring 410 and the female drive ring 420 through the gap 430, then flow into the second rotating sleeve 540, and further flow into the support ring through the drain hole on the second rotating sleeve 540. Finally, it flows out to the designated position through the drain hole on the support ring, thereby reducing the amount and range of cutting fluid splashing and making it easier for workers to clean up the site after grinding.

[0066] In a further embodiment, the suction assembly 200 includes a first linear drive source 210, a connecting support 220, and a vacuum suction cup 230. The fixed end of the first linear drive source 210 is located at the front of the base 110. The first linear drive source 210 can be any one of a hydraulic rod, a cylinder, or an electric telescopic rod. The connecting support 220 is connected to the telescopic end of the first linear drive source 210, and the vacuum suction cup 230 is rotatably connected to the connecting support 220.

[0067] When holding the tile 900, first activate the vacuum suction cup 230 to hold the tile 900 on the vacuum suction cup 230. Then activate the first linear drive source 210. At this time, the first linear drive source 210 drives the vacuum suction cup 230 to move synchronously in the vertical direction through the connecting support 220. The vacuum suction cup 230 drives the tile 900 to move synchronously until the middle surface of the tile 900 in the vertical direction is flush with the center surface of the friction plate 630 in the vertical direction.

[0068] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0069] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the appended claims.
