Detailed implementation manners

[0032] The following is combined with the attached Figure 1 to the attached Figure 11The principles and features of the present utility model are described. The examples given are only for explaining the present utility model and are not intended to limit the scope of the present utility model.

[0033] In the following description, "X-direction movement", "Y-direction movement", and "Z-direction movement" can refer to the X-direction, Y-direction, and Z-direction in the attached Figure 7 drawing.

[0034] An automatic blade grinding device for a tile cutter, as Figure 1 — Figure 5 shown, includes a central turntable 1. The central turntable 1 can be rotated by a motor drive. There are multiple sets of carriers 5 for fixing the tile cutter 6 on the central turntable 1. A magazine automatic feeding component 2, a blade grinding component 3, and an automatic material collecting component 4 are sequentially arranged at the circumferential position of the central turntable 1. In order to meet the sharpness requirement of the blade edge and reduce the roughness, the number of the blade grinding components 3 is three groups, which are respectively used for rough grinding, semi-finishing grinding, and finishing grinding of the tile cutter 6. The magazine automatic feeding component 2 includes a pushing device 7 and a positioning device 8. The pushing device 7 can push the tile cutter 6 onto the carrier 5, and the positioning device 8 can preliminarily limit the position of the tile cutter 6. The blade grinding component 3 includes a blade making device 10 and a displacement adjusting device 9 for adjusting the position of the blade making device 10. The automatic material collecting component 4 includes an automatic grasping device 11 and a conveyor belt 12. The automatic grasping device 11 can transfer the ground tile cutter 6 to the conveyor belt 12 for centralized material collection.

[0035] The carrier 5 includes a tile cutter fixing seat 13 and a clamping device 14. The tile cutter fixing seat 13 is provided with an arc top 15 that matches the shape of the tile cutter 6. The tile cutter fixing seat 13 is also provided with a first limiting post 16 and a second limiting post 17 for restricting the axial and circumferential displacement of the tile cutter 6 along the arc top 15. The tile cutter 6 from the pushing device 7 can achieve movement and stop in place under the blocking of the first limiting post 16. At the same time, the second limiting post 17 can prevent the tile cutter 6 from shifting in the circumferential direction, ensuring the accurate position of the prefabricated hole 601 of the tile cutter 6 on the carrier 5. The prefabricated hole 601 is the position to be ground. In order to achieve multiple-point accurate blocking in the axial direction, in this embodiment, the number of the first limiting posts 16 is two groups.

[0036] As Figure 8As shown, the pusher device 7 is provided with a push plate 701. At one end of the push plate 701 away from the central turntable 1, there is a pusher cylinder 702. The end of the push plate 701 and the rod end of the pusher cylinder 702 are fixed on the first slider 703. A matching first slide rail 704 is provided at the bottom of the first slider 703. The push plate 701 can reciprocate under the action of the pusher cylinder 702. At the other end of the push plate 701, there is a loading platform 705. The loading platform 705 is in contact with the bottom surface of the push plate 701. Above the loading platform 705, there is a storage bin 706. In the storage bin 706, tile knives 6 are neatly stacked in the vertical direction. The tile knives 6 can fall in sequence under the action of gravity. The push plate 701 moves along the first slide rail 704 under the action of the pusher cylinder 702. When the rod of the pusher cylinder 702 extends, the push plate 701 contacts the end face of the tile knife 6 and pushes it out onto the carrier 5. During the movement of the tile knife 6, in order to prevent it from skewing, a limiting member 707 for restricting the upward displacement of the tile knife 6 is provided on the side of the outside of the storage bin 706 close to the central turntable 1. In this embodiment, the limiting member 707 is a round rod.

[0037] As Figure 9 shown, the positioning device 8 includes an elastic positioning bracket 36 and a positioning pin 37. The elastic positioning bracket 36 is located above the tile knife fixing seat 13 and can be displaced in the vertical direction by driving with a first cylinder 38 to clamp or loosen the tile knife 6. In order to ensure that the elastic positioning bracket 36 has a certain elastic deformation, in this embodiment, the elastic positioning bracket 36 is made of alloy spring steel and the overall structure is U-shaped. The positioning pin 37 can be displaced in the vertical direction by driving with a second cylinder. During its upward displacement, it can penetrate the tile knife fixing seat 13 and insert into the prefabricated hole 601 of the tile knife 6. The top end of the positioning pin 37 is conical. The tile knife 6 is positioned on the carrier 5 under the action of the push plate 701. The elastic positioning bracket 36 clamps it under the action of the first cylinder 38. The positioning pin 37, under the action of the second cylinder, inserts into the prefabricated hole 601, and the tile knife 6 is accurately positioned through the prefabricated hole 601, and then the position of the tile knife 6 is fixed by the clamping device 14.

[0038] The clamping device 14 includes a limiting plate 18, and an elastic support column 19 and a fixed support column 20 hinged to the limiting plate 18. The elastic support column 19 is located at the end of the limiting plate 18 and away from the tile knife fixing seat 13. The fixed support column 20 is located between the tile knife fixing seat 13 and the elastic support column 19.

[0039] The elastic support column 19 includes a guide column 24. One end of the guide column 24 is provided with an ear plate 22 hinged to the end of the limit plate 18, and the other end is provided with a convex shaft 23. A positioning boss 21 is provided between the ear plate 22 and the convex shaft 23. A guide spring 25 is sleeved outside the convex shaft 23. One end of the guide spring 25 contacts the positioning boss 21, and the other end contacts the central turntable 1. When an external force acts on the end of the limit plate 18 close to the elastic support column 19, the guide spring 25 is compressed, and the limit plate 18 displaces around the hinge point of the fixed support column 20. At this time, the tile knife 6 is in an unfixed state. When the external force is removed, the guide spring 25, under the action of its own elastic force, fixes the tile knife 6.

[0040] As Figure 10 shown, in order to facilitate the clamping and unloading of the tile knife 6, a set of clamping release devices 26 are provided on each side of the magazine automatic loading component 2 and the automatic material collecting component 4. The clamping release device 26 includes a support vertical plate 28 with a first hinge seat 27 at the top, a lifting cylinder 29, and a first connecting rod 30. The middle of the first connecting rod 30 is hinged to the first hinge seat 27. One end of the first connecting rod 30 is hinged to the rod end of the lifting cylinder 29. The other end of the first connecting rod 30 is provided with a first stud 31 connected by a thread pair. By adjusting the thread engagement position of the first stud 31, the compression stroke of the guide spring 25 can be adjusted. The first connecting rod 30 displaces around the hinge point of the first hinge seat 27 under the action of the lifting cylinder 29, so that the first stud 31 exerts a force on the elastic support column 19 end of the limit plate 18, realizing the release of the position fixation of the tile knife 6.

[0041] In order to further adjust the magnitude of the force exerted by the first stud 31 on the limit plate 18, the first connecting rod 30 is also provided with a second stud 32 connected by a thread pair at the place close to the first hinge seat 27. By adjusting the thread engagement position of the second stud 32, the displacement stroke of the first stud 31 can be adjusted, and further adjust the magnitude of the force it exerts on the limit plate 18. In order to make the acting position of the first stud 31 accurate, a second hinge seat 33 is also provided at the tail end of the cylinder block of the lifting cylinder 29. A second connecting rod 34 is hinged to the second hinge seat 33. The second connecting rod 34 is provided with a limit adjusting rod 35 contacting the bottom surface of the central turntable 1, which can make the position of the clamping release device 26 relatively accurate and fixed.

[0042] As Figure 6 and Figure 7 shown, the blade making device 10 includes a grinding head 39 and a fourth motor 40 for driving the grinding head 39 to rotate. The displacement adjusting device 9 includes a first linear guide slide 901 for the blade making device 10 to move in the X direction, a second linear guide slide 902 for moving in the Y direction, and a third linear guide slide 903 for moving in the Z direction. A hoop seat is sleeved outside the blade making device 10 and can be connected to the third linear guide slide 903.

[0043] The first linear guideway slider 901, the second linear guideway slider 902 and the third linear guideway slider 903 are respectively driven by a first motor 904, a second motor 905 and a third motor 906. To save floor space, the first motor 904 and the first linear guideway slider 901 are driven by a first pulley group 907, the second motor 905 and the second linear guideway slider 902 are driven by a second pulley group 908, and the third motor 906 and the third linear guideway slider 903 are directly driven by a coupling. A protective cover 41 for protection is provided outside the blade making device 10.

[0044] As Figure 11 shown, the automatic gripping device 11 includes a first module 42 and a gripper device 43 that can horizontally displace along the first module 42. The gripper device 43 is provided with a pneumatic jaw 44 and a lifting cylinder 45 that enables the pneumatic jaw 44 to displace in the vertical direction. In this embodiment, the specific structures and working principles of the first module 42 and the pneumatic jaw 44 are technical knowledge well-known to those skilled in the art and will not be elaborated here. The gripper device 43 can run above the carrier 5 along the first module 42, and the tile knife 6 is transferred to the conveyor belt 12 through the action of the gripper device 43. The conveyor belt 12 is driven by a fifth motor, and centralized sorting and transfer of the tile knives 6 after edge grinding can be achieved.

[0045] The working principle of this device is as follows: The tile knife 6 is moved onto the carrier 5 under the action of the pusher device 7. The elastic positioning bracket 36, the positioning pin 37, and the clamping device 14 sequentially limit and fix the tile knife 6 on the carrier 5. After the clamping device 14 completes the limiting and fixing, the elastic positioning bracket 36 and the positioning pin 37 are withdrawn under the action of the first cylinder 38 and the second cylinder respectively. The tile knife 6 rotates with the carrier 5 through different workstations to sequentially complete rough grinding, semi-precision grinding, and precision grinding. Under the action of releasing the clamping device 26, the clamping device 14 no longer fixes the tile knife 6, and the automatic gripping device 11 grabs the tile knife 6 onto the conveyor belt 12 to achieve centralized sorting and transfer. This device can realize simultaneous operation of multiple groups of tile knives 6 in different processes, with higher edge grinding efficiency and higher edge grinding precision.

[0046] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
