Description

Edge grinding machine width adjustment device and edge grinding machine Technical Field

[0001] This utility model relates to the field of edge grinding machine technology, and in particular to an edge grinding machine width adjustment device and an edge grinding machine. Background Technology

[0002] The edge grinding machine 200 is a machine used to grind the edges of ceramic tiles. Referring to Figure 1, the prior art edge grinding machine 200 includes a frame 210, a crossbeam 220, a pressure beam 230, and a grinding head 280. Both the crossbeam 220 and the pressure beam 230 are equipped with conveyor belts 240 for conveying the ceramic tiles. Because the widths of the ceramic tiles to be ground vary, the spacing of the crossbeams 220 needs to be adjusted.

[0003] In the existing technology, a guide shaft 250 is used to guide the adjustment movement of the crossbeam 220. However, when the guide shaft 250 guides the crossbeam 220, the large clearance between the guide shaft and the crossbeam 220 can easily cause the guide shaft to deform, resulting in a high defect rate in the polishing of tiles and affecting production quality. Summary of the Invention

The second guide rail base is provided with a second receiving groove, and the second guide rail body is disposed in the second receiving groove. The second receiving groove is used to receive lubricating oil.

[0019] In some embodiments, the edge grinding machine width adjustment device further includes a conduit and a sealing plug. One end of the conduit is located at the bottom of the first guide rail base or the second guide rail base, and the inner cavity of the conduit is connected to the first receiving groove or the second receiving groove. The sealing plug is located at the other end of the conduit and is used to open or close the conduit.

[0020] In some embodiments, the edge grinding machine width adjustment device further includes multiple waterproof covers, which are arranged one-to-one above the first guide rail and the second guide rail, and are used to cover the first guide rail and the second guide rail;

[0028] (2) Furthermore, compared with the existing technology of using a guide shaft, since there is only one fitting gap between the guide rail and the slider mounted on the crossbeam, the fitting gap between the guide shaft and the pressure cap in the existing technology is eliminated, the fitting gap between the parts is reduced, the deformation space of the guide rail is smaller, the probability of deformation is reduced, the accuracy of supporting the tile is higher, thus making the tile grinding more precise and improving the product yield.

[0029] (3) Since the first guide rail and the second guide rail can be supported and installed on the frame, and the lower end face is supported by the frame, compared with the method of using the guide shaft, the suspended installation method is avoided, ensuring the support strength of the first guide rail and the second guide rail, reducing the possibility of deformation, and thus improving the subsequent processing accuracy of the ceramic tile.

Detailed Implementation

[0042] To better understand and implement this invention, the technical solutions in the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings.

[0043] In the description of this utility model, it should be noted that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0044] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0045] The present invention will now be described in further detail with reference to the accompanying drawings.

[0046] Please refer to Figures 1 to 3. In the prior art, the adjustment of the crossbeam 220 is guided by the guide shaft 250. Specifically, during installation, welding holes need to be made in the crossbeam 220, and guide tubes 260 are welded to the welding holes. A pressure cap 270 is then bolted to the guide tube 260. The pressure cap 270 and the guide shaft 250 are slidably set. As a result, the structural strength of the crossbeam 220 is reduced due to the holes in the crossbeam 220.

[0047] Furthermore, in the existing technology, the guide shaft 250 is mounted on the frame with three-point support (two support points at both ends and one support point in the middle). That is, the two ends and the middle position are supported by the frame, while the other areas are suspended. At the same time, due to the fit gap between the guide tube 260 and the pressure cap 270, and the fit gap between the pressure cap 270 and the guide shaft 250, when the grinding head 280 grinds the tile 300, it applies a force to the tile from the side and above, and the tile generates an outward reaction force. This reaction force is applied to the guide shaft 250. Due to insufficient rigidity, the guide shaft 250 is prone to deformation, for example, bending upward into an "m" structure. During continuous grinding, the grinding accuracy of the tile 300 is not affected. However, when the machine is stopped and restarted, the guide shaft 250 returns to its original shape when the machine is stopped. When the machine is restarted, the guide shaft cannot initially maintain a stable state. Thus, the initial grinding accuracy of each batch of tiles is low, affecting the grinding quality. To solve the above-mentioned technical problems, please refer to Figures 4 to 8. The edge grinding machine width adjustment device 100 provided in the embodiment of this utility model includes a frame 10, a guide structure 20, a crossbeam 30, a mounting structure 40, and a drive mechanism 50.

[0048] Referring to Figures 4 to 10, the frame 10 serves as the mounting base; the guide structure 20 includes two first guide rails 21 and at least one second guide rail 22, which are mounted separately on the frame 10 along the Y direction, and the second guide rail 22 is located between the two first guide rails 21, with the first guide rails 21 and the second guide rail 22 extending along the X direction respectively; the crossbeam 30 includes two beams, which are separated along the X direction and each beam 30 extends towards the Y direction; the mounting structure 40 includes four first mounting bases 41 and at least two... The second mounting base 42 is located between the four first mounting bases 41. Each pair of second mounting bases 41 is located at both ends of a crossbeam 30 and is slidably engaged with the first guide rail 21. Each pair of second mounting bases 42 is slidably engaged with a second guide rail 22. Each second mounting base 42 is used to support the crossbeam 30 and to limit the range of motion of the crossbeam 30 in the X direction. The drive mechanism 50 includes at least one mechanism for driving the crossbeam 30 to slide relative to the first guide rail 21 and the second guide rail 22 to adjust the distance between the two crossbeams 30.

[0049] The aforementioned edge grinding machine width adjustment device 100 guides the first mounting base 41 and the second mounting base 42 by setting the first guide rail 21 and the second guide rail 22 respectively. Since the first mounting base 41 and the second mounting base 42 slide directly on the corresponding first guide rail 21 and second guide rail 22, the method of using guide rails to guide and adjust the crossbeam 30 is different from the existing method of using guide shafts for guidance.

[0050] (1) It avoids cutting holes and welding guide tubes on the crossbeam 30, simplifies the installation structure, ensures the structural strength of the crossbeam, and improves the torsional strength of the crossbeam 30.

[0051] (2) Furthermore, compared with the existing technology of using a guide shaft, since there is only one fitting gap between the guide rail and the slider mounted on the crossbeam, the fitting gap between the guide shaft and the pressure cap in the existing technology is eliminated, the fitting gap between the parts is reduced, the deformation space of the guide rail is smaller, the probability of deformation is reduced, the accuracy of supporting the tile is higher, thus making the tile grinding more precise and improving the product yield.

[0052] (3) Since the first guide rail 21 and the second guide rail 22 can be supported and installed on the frame 10, and the lower end face is supported by the frame 10, compared with the method of using the guide shaft 250, the suspended installation method is avoided, ensuring the support strength of the first guide rail 21 and the second guide rail 22, reducing the possibility of deformation, thereby improving the initial processing accuracy of each batch of tiles and reducing the initial defect rate of each batch.

[0053] It should be noted that the first guide rail 21 and the second guide rail 22 in this embodiment are square guide members, while the guide shaft in the prior art is a columnar guide member. The X direction refers to the length direction of the first guide rail 21 or the second guide rail 22, the Y direction refers to the length direction of the crossbeam, and the Z direction refers to the height direction of the frame 10.

[0054] The second guide rail 22 can be provided with one, two, or more second guide rails 22 depending on the length of the crossbeam 30. Specifically, in this embodiment, one second guide rail 22 is provided, which not only supports the crossbeam 30 but also facilitates the installation of the entire edge grinding machine width adjustment device 100. Correspondingly, two second mounting seats 42 are slidably disposed on the second guide rail 22, and one second mounting seat 42 is used to support the middle area of ​​a crossbeam 30.

[0055] Correspondingly, the rack 10 in this embodiment includes a main frame 11 and at least three sub-frames 12. The three sub-frames 12 are arranged side by side along the Y direction. One sub-frame 12 supports a pair of first mounting seats 41, and the middle sub-frame 12 supports two second mounting seats 42.

[0056] When sliding, the first guide rail 21 slides with the crossbeam 30 through the first mounting base 41, and the second guide rail 22 slides with the crossbeam 30 through the second mounting base 41.

[0057] The drive mechanism 50 can be installed on the ground or on the frame 10. It can transmit the driving force to the first mounting base 41 or the second mounting base 42 to drive the crossbeam 30 to move, or it can directly apply the driving force to the crossbeam 3 to drive the crossbeam 30 to move.

[0058] Specifically, the drive mechanism 50 in this embodiment includes a drive motor, a reducer, and a screw. The screw is rotatably connected to the first mounting base 41. Under the drive of the drive motor, the screw rotates to drive the first mounting base 41 to move. The movement of the first mounting base 41 drives the crossbeam 30 to move, thereby adjusting the distance between the two crossbeams 30.

[0059] Understandably, since the crossbeam 30 has a certain extension length, it has a certain weight. In order to achieve stable driving of the crossbeam 30, the edge grinding machine width adjustment device 100 of this embodiment includes two driving mechanisms 50. Along the Y direction, each crossbeam 30 is provided with a driving mechanism 50 at one end, so that the distance between the two crossbeams 30 can be adjusted simultaneously by the two driving mechanisms 50 to ensure driving power.

[0060] Please refer to Figure 8. In one embodiment of this utility model, since the grinding head generates a pushing force on the tile when grinding it, and the tile generates a reaction force on the crossbeam 30, causing the crossbeam 30 to tend to move, the edge grinding machine width adjustment device 100 in this embodiment also includes multiple locking devices 90. The multiple locking devices 90 and multiple second mounting seats 42 are arranged one-to-one to lock the second mounting seats 42 onto the second guide rail 22. Thus, after the spacing of the crossbeam 30 is adjusted, the locking devices 90 lock the second mounting seats 42 onto the second guide rail 22, so that the second mounting seats 42 cannot move relative to the second guide rail 22, thereby avoiding the crossbeam 30 from being deformed by the reaction force during the grinding process, thereby achieving the effect of accurately controlling the grinding accuracy of the tile.

[0061] Specifically, in this embodiment, the locking device 90 is a clamp. In other embodiments, for example, the locking device 90 can be set as a cylinder. When the crossbeam 30 is adjusted to the position, the cylinder abuts against the second guide rail 22, thereby restricting the sliding of the second mounting base 42 relative to the second guide rail 22.

[0062] Furthermore, when configuring the locking device 90, it is installed on one side of the second mounting base 42 along the X direction. That is, by providing only one locking device 90 on one side of the second mounting base 42, the locking effect of the second mounting base 42 can be achieved, and the installation of the locking device 90 can be facilitated, reducing installation costs. In other embodiments, it may be necessary to provide locking devices 90 on both opposite sides of the second mounting base 42 along the X direction.

[0063] Referring to Figure 7, since the second mounting base 42 not only supports the crossbeam 30 but also drives the crossbeam 30 to slide along the guide rail, the edge grinding machine width adjustment device 100 includes multiple limiting structures 60. Each second mounting base 42 has a limiting structure 60 at both ends along the X direction. The limiting structure 60 is used to limit the movement of the crossbeam 30 along the X direction. Since the first mounting base 41 and the crossbeam 30 are fixedly connected (the fixed connection here means that the two cannot move relative to each other; during installation, a welded fixed installation method or a bolted detachable connection method can be used), in this case... (Not limited) Driven by the drive mechanism 50, the crossbeam 30 can move upward in the X direction. However, since the crossbeam 30 has a certain extension length, it is necessary to support the crossbeam 30 in the middle area and restrict the deformation of the crossbeam 30 in the X direction. Therefore, the second mounting seat 42 in the middle and the crossbeam 30 are in a movable contact manner, and the crossbeam 30 is not locked on the second mounting seat 42 to avoid the crossbeam 30 getting stuck when it is installed with the first mounting seats 41 at both ends. The movable support method of the second mounting seat 42 and the crossbeam 30 is realized by setting the limiting structure 60.

[0064] Specifically, the limiting structure 60 in this embodiment includes a limiting block 61 and a first bolt 62. The first bolt 62 is threadedly connected to the limiting block 61 and the second mounting base 42 respectively. The limiting block 61 is used to abut against the crossbeam 30 when the crossbeam 30 moves in the X direction, so as to limit the crossbeam 30 in the X direction. That is, the limiting block 61 is installed on the second mounting base 42 by the first bolt 62. When the crossbeam 30 moves in the X direction and contacts the limiting block 61, it stops moving in that direction, so as to limit the degree of freedom of the crossbeam 30.

[0065] Furthermore, when setting the limiting structure 60, the crossbeam 30 includes a base 31 and a beam 32. The base 31 is connected to the first mounting base 41 or the second mounting base 42. The beam 32 extends along the X direction. The base 31 is provided with a notch 311. The limiting block 61 is set corresponding to the notch 311. Thus, when the second mounting base 42 moves along the X direction and touches the crossbeam 30, it can drive the crossbeam 30 to move, so that the installation of the crossbeam 30 can have a certain degree of freedom. The setting of the limiting block 61 also prevents the crossbeam 30 from undergoing excessive deformation when subjected to the force applied by the tile. By setting the notch 311 on the base 31 and setting the limiting block 61 in the notch 311, the overall uniformity of the second mounting base 42 can be ensured after the limiting block 61 is installed on the second mounting base 42.

[0066] Understandably, in this embodiment, guide rails are used instead of guide shafts to allow the crossbeam 30 to slide. That is, the frame 10 has an upper surface that extends synchronously in the Z direction with the lower surfaces of the first guide rail 21 and the second guide rail 22. The lower surfaces of the first guide rail 21 and the second guide rail 22 are connected to the upper surface. For example, the upper surface of the frame and the lower surfaces of the two guide rails may abut against each other. Alternatively, the upper surface of the frame and the lower surfaces of the two guide rails may be connected by welding or bonding, so that the lower surfaces of the first guide rail 21 and the second guide rail 22 in this embodiment can be supported by the frame 10, avoiding a suspended state and reducing the probability of deformation when subjected to force.

[0067] Specifically, please refer to Figure 5. The frame 12 of this embodiment includes two support legs 121 separated along the X direction and a support beam 122 connected between the two support legs 121. The support beam 122 extends in the same direction as the first guide rail 21 or the second guide rail 22 and is supported on the bottom surface of the first guide rail 21 or the second guide rail 22. It is installed in close contact with the bottom surface so that the frame 10 can form a continuous and unsuspended support state for the first guide rail 21 or the second guide rail 22 along the X direction, thereby reducing the possibility of deformation of the first guide rail 21 or the second guide rail 22.

[0068] Specifically, the first mounting base 41 includes a first mounting plate 412 and a first sliding seat 413 disposed at the bottom of the first mounting plate 412, the first sliding seat 413 and the first guide rail 21 being slidably engaged; similarly, the second mounting base 42 includes a second mounting plate 422 and a second sliding seat 423 disposed at the bottom of the second mounting plate 422, the second sliding seat 423 and the second guide rail 21 being slidably engaged, thus, sliding relative to the first guide rail 21 or the second guide rail 22 is achieved through the first sliding seat 413 and the second sliding seat 423.

[0069] Please refer to Figures 9 and 10. To prevent the first guide rail 21 or the second guide rail 22 from rusting after long-term use, the first guide rail 21 includes a first guide rail base 211 and a first guide rail body 212. The first guide rail base 211 is provided with a first receiving groove 213, and the first guide rail body 212 is disposed in the first receiving groove 213. The first receiving groove 213 is used to receive lubricating oil. The second guide rail 22 includes a second guide rail base 221 and a second guide rail body 222. The second guide rail base 221 is provided with a second receiving groove 223, and the second guide rail body 222 is disposed in the second receiving groove 223. The second receiving groove 223 is used to receive lubricating oil.

[0070] Thus, by placing the first guide rail 21 or the second guide rail 22 in the first receiving groove 213 or the second receiving groove 223, and placing lubricating oil in the corresponding receiving groove, not only does it lubricate the movement of the first mounting base 41 or the second mounting base 42 relative to the guide rail, but the lubricating oil can also coat the surface of the first guide rail 21 or the second guide rail 22, preventing the first guide rail 21 and the second guide rail 22 from coming into contact with water and oxygen, thus preventing rust.

[0071] Specifically, the first guide rail base 211 includes a first base plate 2111 and two first side plates 2112 disposed on opposite sides of the first base plate 2111 along the Y direction. The first base plate 2111 and the two first side plates 2112 form a first receiving groove 213. The second guide rail base 221 has the same structure as the first guide rail base 211, and will not be described in detail here.

[0072] Furthermore, since moisture may enter the receiving groove 71 during long-term use of the edge grinding machine, in order to prevent lubricating oil from overflowing out of the first receiving groove 213 or the second receiving groove 223, an oil discharge port 76 is provided on the side wall of the first guide rail base 211 or the second guide rail base 221 in this embodiment. For example, it is provided on the side wall or the bottom wall of the first guide rail base 211 or the second guide rail base 221, so that when the grease capacity in the first receiving groove 213 or the second receiving groove 223 increases, the grease can be discharged into a predetermined container through the oil discharge port 76, avoiding overflow into the environment along the opening of the first guide rail base 211 or the second guide rail base 221 and polluting the environment.

[0073] Furthermore, in order to facilitate the control of the amount of grease discharged, the edging machine width adjustment device 100 also includes a conduit 74 and a sealing plug 75. One end of the conduit 74 is located at the bottom of the first guide rail base 211 or the second guide rail base 221, that is, at the oil discharge port 76, and the inner cavity of the conduit 74 is connected to the receiving groove 71. The sealing plug 75 is located at the other end of the conduit 74 and is used to open or close the conduit 74. When the fluid capacity in the receiving groove 71 gradually increases after the edging machine has been used for a long time, the sealing plug 75 can be opened to discharge the grease in the receiving groove 71 and control the amount of grease discharged. When the amount of remaining oil in the receiving groove 71 meets the preset amount, the conduit 74 can be blocked by the sealing plug 75.

[0074] Please refer to Figures 4, 9, and 10. In one embodiment of this utility model, to prevent excessive impurities or water flow from eroding the first guide rail 21 or the second guide rail 22, the edge grinding machine width adjustment device 100 further includes multiple waterproof covers 80. The multiple waterproof covers 80 are arranged in a one-to-one correspondence with the first guide rail 21 and the second guide rail 22. The first mounting base 41 is provided with a first through groove 411 extending in the X direction and matching the cross-sectional shape of the waterproof cover 80. The second mounting base 42 is provided with a second through groove 421 extending in the X direction and matching the cross-sectional shape of the waterproof cover 80. The multiple waterproof covers 80 are respectively inserted into the first through groove 411 and the second through groove 421. Thus, by providing waterproof covers 80 outside the first guide rail 21 or the second guide rail 42, the waterproof covers 80 can block impurities or water flow, thereby reducing the amount of contact with the first guide rail 21 or the second guide rail 22, and thus protecting the first guide rail 21 and the second guide rail 22.

[0075] Specifically, the waterproof cover 80 is an arched shape with its opening facing downwards, and the extension length of the waterproof cover 80 in the X direction is greater than the extension lengths of the first guide rail 21 and the second guide rail 22, respectively. Both ends are connected to support feet 121 to protect the first guide rail 21 and the second guide rail 22. Furthermore, the sides of the waterproof cover 80 are lower than the lower surface of the first guide rail base 211 or the second guide rail base 221, thereby achieving a better waterproof effect.

[0076] When installing the waterproof cover, please refer to Figure 9. The first mounting base 41 also includes a first upper base plate 414, two first outer side plates 415 disposed on both sides of the first upper base plate 414 along the X direction, two first inner side plates 416 disposed on both sides of the first mounting plate 412 along the X direction, and a first connecting plate 417 connecting each first outer side plate 415 and each first inner side plate 416. The first outer side plates 415 and the first inner side plates 416 are arranged in parallel and separated, and the first upper base plate 414 and the first mounting plate 412 are arranged in parallel and separated, so that the first upper base plate 414, the first outer side plates 415, the first mounting plate 412 and the first inner side plates 416 surround to form a first through groove 411 that mates with the waterproof cover 80.

[0077] Correspondingly, please refer to Figure 10. The second mounting base 42 and the first mounting base 40 have the same structure and form the through groove for the waterproof cover 80 in the same way. The second mounting base 42 also includes a second upper base plate 424, two second outer side plates 425 disposed on both sides of the second upper base plate 424 along the X direction, two second inner side plates 426 disposed on both sides of the second mounting plate 422 along the X direction, and a second connecting plate 427 connecting each second outer side plate 425 and each second inner side plate 426. The second outer side plates 425 and the second inner side plates 426 are arranged in parallel and separated, and the second upper base plate 424 and the second mounting plate 422 are arranged in parallel and separated, so that the second upper base plate 424, the second outer side plates 425, the second mounting plate 422 and the second inner side plates 426 surround and form a second through groove 421 that cooperates with the waterproof cover 80. The aforementioned edge-grinding machine width adjustment device 100, by setting a locking device 90 on the second mounting base 42, can lock the second mounting base 42 onto the second guide rail 22 after the adjustment of the crossbeam 30 is completed. This prevents the crossbeam 30 from deforming due to relative movement between the crossbeam 30 and the second guide rail 22 caused by the reaction force of the tile during subsequent tile grinding. By setting a limiting structure 60 on the second mounting base 42, the middle position of the crossbeam 30 can be movably connected to the second mounting base 42, facilitating the installation of both ends of the crossbeam 30 with the first mounting base 41 respectively, and preventing the crossbeam 30 from getting stuck. By installing each guide rail into the receiving groove 71 of the base 70, the lubricating oil in the receiving groove 71 blocks water and oxygen from each guide rail, preventing the first guide rail 21 or the second guide rail 22 from rusting due to excessive contact with water and oxygen. The waterproof cover 80 above each guide rail can prevent dust and other impurities from entering the receiving groove 71, achieving cleaning and protection of the guide rail.

[0078] In another embodiment of the present invention, an edge grinding machine is also provided, including the above-mentioned edge grinding machine width adjustment device 100, wherein the edge grinding machine also includes a conveyor belt, a grinding head and other structures.

[0079] The technical means disclosed in this utility model are not limited to those disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications are also considered within the scope of protection of this utility model.
