Description

Technical Field

[0001] The utility model relates to the technical field of stone chamfering and grinding, in particular to an ecological stone chamfering and grinding device. Background Art

[0002] Stone chamfering is the process of beveling or rounding the edges of a stone to achieve both aesthetic and safety benefits. This process not only enhances the overall appearance of the stone but also reduces the risk of injury from sharp edges.

[0003] According to the patent announcement number: CN214353357U, announcement date: 2021-10-08, a stone-like curbstone chamfering cutting machine is disclosed, including a limit frame, at least one top corner of the limit frame is a right angle, and an inclined support frame is provided at the corner, and a cutting device is fixedly connected to the support frame.

[0004] In the prior art, including the aforementioned patent, chamfering of ecological stone is currently performed using a cutting machine. The stone is moved close to the cutting machine to form a chamfer, i.e., a corner with a certain inclined surface. However, due to the cutting process, the inclined surface of this chamfer still has a certain angle with the top and side surfaces. These angles need to be manually polished to form curved corners, thereby further reducing sharp edges. However, manual polishing is tedious and can only be performed on a single corner.

[0023] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0024] like Figure 1-5 As shown, an ecological stone chamfering and grinding device includes a stone plate 4, a cutting table 1, and a conveyor belt 14 for transmission. A cutting motor 2 is provided on the top of the cutting table 1 on one side of the conveyor belt 14, and a cutting disc 21 is fixedly installed on the output end of the cutting motor 2. The cutting disc 21 is movably arranged on the edge of the stone plate 4 to cut and form a bevel chamfer 41 and obtuse edges 42 on both sides of the bevel chamfer 41. The chamfering and grinding unit provided on the top of the cutting table 1 on one side of the cutting motor 2 includes:

[0025] The support member 3 has an arc-shaped extension frame 6 symmetrically arranged thereon, and a moving block 63 is slidably arranged in an arc-shaped groove 61 provided on the arc-shaped extension frame 6;

[0026] The grinding motor 5 is fixedly mounted on the moving block 63, and a grinding wheel 51 fixedly mounted at the output end of the grinding motor 5 is movably mounted on the obtuse-angled edge 42. After the stone slab 4 is cut into the chamfered surface 41 by the cutting disc 21, as the stone slab 4 moves on the conveyor belt 14, the grinding motor 5 drives the grinding wheel 51 to simultaneously grind the obtuse-angled edges 42 on both sides of the chamfered surface 41. The moving block 63 then slides within the arcuate groove 61, causing the grinding wheel 51 to grind the obtuse-angled edge 42 into a curved surface. This improves efficiency compared to manual single-edge grinding.

[0027] Specifically, a first mounting plate 15 and a second mounting plate 16 are fixedly mounted on the top of the cutting table 1. The cutting motor 2 is fixedly mounted on the first mounting plate 15, and the support member 3 is fixedly mounted on the second mounting plate 16. The cutting table 1 is provided with conveyor rollers and a motor for driving the conveyor belt 14. The motor drives the conveyor rollers, which drives the conveyor belt 14 and drives the stone slab 4 close to the cutting motor 2 for cutting.

[0028] As a further technical solution provided by the present invention, a push rod 35 is slidably provided on the support member 3 , and a connecting rod 36 is symmetrically hingedly provided on the push rod 35 , and a first end of the connecting rod 36 is hingedly provided on the moving block 63 .

[0029] Specifically, in order to simultaneously drive the two moving blocks 63 to slide in the arc groove 61, the push rod 35 is slid on the support member 3, thereby cooperating with the connecting rod 36 to simultaneously drive the two moving blocks 63 to slide in the arc groove 61. At this time, the grinding motor 5 on the two moving blocks 63 moves to grind and trim the obtuse edge 42.

[0030] Furthermore, a main motor 31 is fixedly mounted on the support member 3, and a main gear 32 is fixedly mounted on the output end of the main motor 31. A swing arm 34 is hingedly mounted on an eccentric shaft 33 eccentrically arranged on the main gear 32, and a first end of the swing arm 34 is hingedly mounted on a push rod member 35.

[0031] Specifically, the main motor 31 is used to drive the main gear 32 to rotate, and then the main gear 32 cooperates with the swing rod 34 to reciprocate and pull the push rod 35 to slide on the support member 3. At this time, the grinding motor 5 slides back and forth in the arc groove 61, thereby realizing the continuous grinding operation of the obtuse angle edge 42 on the stone plate 4.

[0032] Furthermore, a bolt 62 is provided at the first end of the arc-shaped extension frame 6 .

[0033] Specifically, a through hole is provided at the first end of the arc-shaped extension frame 6. The arc-shaped extension frame 6 is quickly installed by passing the bolt member 62 through the through hole and then threading the bolt member 62 to be set on the support member 3. The arc-shaped extension frame 6 is detachable to facilitate the subsequent replacement of arc-shaped extension frames 6 of different shapes, thereby performing grinding operations on the obtuse-angled edges 42 with different deformation requirements.

[0034] Furthermore, a retaining frame 11 is fixedly mounted on the cutting table 1 , and a limiting frame 12 is fixedly mounted on the retaining frame 11 . A plurality of guide wheels 13 are rotatably mounted on the bottom of the limiting frame 12 .

[0035] Specifically, by using the limit frame 12 and the guide wheel 13 to be located above the stone slab 4, when the conveyor belt 14 causes vibration when transporting the stone slab 4, the limit frame 12 and the guide wheel 13 are used to limit the amplitude of the vibration, thereby improving the flatness of the chamfer 41.

[0036] Furthermore, there may be multiple chamfer grinding units.

[0037] Specifically, by using a plurality of chamfer grinding units, the smoothness of the grinding of the obtuse-angled edge 42 can be improved.

[0038] Working principle: The main motor 31 drives the main gear 32 to rotate, and then the main gear 32 cooperates with the swing rod 34 to reciprocate and pull the push rod 35 to slide on the support 3. At this time, the grinding motor 5 slides back and forth in the arc groove 61, thereby realizing the continuous grinding of the obtuse angle edge 42 on the stone plate 4, and the two grinding motors 5 drive the grinding wheel 51 to grind the obtuse angle edges 42 on both sides of the bevel chamfer 41 at the same time, which is more efficient than manual single-sided grinding.

[0039] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
