Description

Technical Field

[0001] The utility model relates to the technical field of marble grinding, in particular to a grinding device for producing marble slabs. Background Art

[0002] Marble is widely used, especially in the fields of architecture and sculpture. Due to its unique texture and color, marble is often used to make floors, walls, countertops, sculptures, etc. In addition, marble is suitable for indoor and outdoor environments due to its high wear resistance and corrosion resistance. Marble slabs are rectangular slabs cut from marble. In the field of decoration, marble slabs are generally cut into certain sizes for use as floors, countertops, etc. After the marble slabs are cut, their edges are relatively sharp. In order to avoid injuries to workers when carrying and installing marble slabs, a grinding device is needed to grind the edges of the marble slabs.

[0003] At present, most of the grinding devices on the market have relatively fixed positions of the grinder and the clamping plate when grinding marble slabs, and can only grind one edge of the marble slab at a time. When grinding the entire marble slab, workers need to rotate the marble slab in the middle of the process and align the four edges with the grinder one by one, which not only increases the workload and operation difficulty of the workers, but also reduces work efficiency. At the same time, the frequent rotation of the marble slab may also increase the risk of damage to the slab during transportation. Utility Model Content

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-3 In this embodiment, a grinding device for marble slab production is provided. The rotating motor 23 installed at the bottom end of the top plate of the base 1 drives the second gear 24 to rotate, so that the first gear 22 drives the support platform 2 to rotate in coordination with the first gear 22 under the cooperation of the positioning rod 21 and the bearing. Thus, the four edges of the marble slab placed on the support platform 2 can be made to correspond to the grinder 47 one by one under the rotation; driven by the extension of the output shaft of the first cylinder 3, the distance between the grinder 47 and the support platform 2 can be adjusted, so that the grinder 47 can be fitted with the four edges of the marble slab to grind the marble slab. There is no need for workers to manually rotate the marble slab during the grinding process, which greatly reduces the workload of workers, speeds up the grinding speed, and improves the overall work efficiency.

[0023] Specifically, a grinding device for marble slab production in this embodiment includes a base 1, a support platform 2 is vertically penetrated and clamped along one side of the upper surface of the top plate of the base 1, and the support platform 2 is rotatably connected to the base 1 through a bearing;

[0024] A positioning rod 21 is installed at the center of the bottom end of the support platform 2, and a first gear 22 is sleeved on the outer wall of the positioning rod 21. A rotating motor 23 is installed at the bottom end of the top plate of the base platform 1. The output shaft of the rotating motor 23 is arranged downward and a second gear 24 is sleeved on the outer wall. The first gear 22 and the second gear 24 are located on the same horizontal line and meshed with each other.

[0025] A first cylinder 3 is installed on the upper surface of the top plate of the base 1 along the longitudinal edge of the base 1. The output shaft of the first cylinder 3 is arranged toward the support platform 2 and a receiving plate 31 is installed at the tail end. A grinding assembly 4 is installed on the upper surface of the receiving plate 31. The grinding assembly 4 includes a grinder 47. The output end of the grinder 47 is arranged toward the support platform 2.

[0026] During actual use, the user places the marble slab on the support table 2 so that one side edge of the marble slab is parallel to the grinder 47. The user controls the first cylinder 3 to operate so that its output shaft can perform reciprocating motion of extending outward and retracting, thereby pushing the grinder 47 to fit one of the edges of the marble slab to grind it. Then, the user controls the rotary motor 23 to operate so that its output shaft can drive the second gear 24 to rotate, thereby enabling the first gear 22 to drive the positioning rod 21 and the support table 2 as well as the marble slab placed on the support table 2 to rotate in coordination with the rotation of the first gear 22, so that the other three edges of the marble slab can respectively correspond to the grinder 47. The user controls the first cylinder 3 to operate again so as to push the grinder 47 to fit the other three edges of the marble slab respectively for grinding. There is no need for workers to manually rotate the marble slab during the grinding process, thereby greatly reducing the workload of workers, speeding up the grinding speed, and improving the overall work efficiency.

[0027] The second gear 24 is configured in the same manner as the first gear 22, and the teeth on the first gear 22 only account for one quarter of the teeth on the first gear 22. The second gear 24 is obtained by dividing an original gear and removing three quarters of all the teeth, so that the second gear 24 has a free movement period of three quarters during one movement, and forms a spacing distance with the first gear 22, so that the second gear 24 rotates one circle, and the first gear 22 drives the support platform 2 to rotate ninety degrees. As a result, each edge of the marble slab of the support platform 2 can be parallel to the grinder 47 during the rotation process, so as to prevent the edge of the marble slab from being tilted between the grinder 47 after rotation, thereby affecting the grinding effect.

[0028] A frame 5 is installed on the upper surface of the top plate of the base 1 along one lateral edge of the base 1, and a second cylinder 51 is installed at the bottom end of the top plate of the frame 5. A rotating rod is connected between the second cylinder 51 and the top plate of the frame 5, and the rotating rod is rotatably connected to the frame 5 through a bearing.

[0029] The output shaft of the second cylinder 51 is arranged downward and a suction cup 53 is installed at the bottom end. The suction cup 53 corresponds to the center of the upper surface of the support platform 2.

[0030] During actual use, after the user places the marble slab on the support table 2, the user controls the operation of the second cylinder 51, and the output shaft of the second cylinder 51 drives the suction cup 53 to extend downward, so that the marble slab is clamped between the support table 2 and the suction cup 53, so as to prevent the marble slab from shifting during the grinding process and the rotation of the support table 2; under the action of the bearing, when the support table 2 rotates, the suction cup 53 and the second cylinder 51 can also rotate together.

[0031] The grinding assembly 4 includes mounting plates 41 mounted on the upper surface of the receiving plate 31 along the two lateral edges of the base 1 , and a reciprocating motor 42 and a bearing seat 43 are respectively mounted on the opposite surfaces of the two mounting plates 41 .

[0032] The output shaft of the reciprocating motor 42 is set toward the bearing seat 43 and a threaded screw 44 is installed at the tail end. The outer wall of the other end of the threaded screw 44 is connected to the inner wall of the inner ring of the bearing inside the bearing seat 43. A slider 45 is meshed and slidably engaged on the threaded screw 44, and a grinder 47 is installed on the upper surface of the slider 45 close to the support platform 2.

[0033] During actual use, the user controls the operation of the reciprocating motor 42. With the cooperation of the bearing inside the bearing seat 43, the reciprocating motor 42 operates its output shaft to drive the threaded screw 44 to rotate in both clockwise and counterclockwise directions, thereby enabling the slider 45 to drive the grinder 47 to reciprocate within the travel range of the threaded screw 44, so that the grinder 47 can completely grind every edge of the marble slab.

[0034] Two limiting rods 46 are installed between the two mounting plates 41 and are located on both sides of the threaded screw 44 . The two limiting rods 46 both penetrate the slider 45 , and the slider 45 is slidably connected to the two limiting rods 46 .

[0035] Under the restriction of the limiting rod 46 , when the threaded screw 44 rotates, the slider 45 moves linearly on the threaded screw 44 to prevent the slider 45 from rotating.

[0036] A dust collector 48 is installed on a side of the upper surface of the sliding block 45 away from the supporting platform 2 , and an action end of the dust collector 48 is arranged toward the supporting platform 2 .

[0037] The vacuum cleaner 48 can absorb the debris and dust generated by the grinder 47 when grinding the marble slab to avoid polluting the environment.

[0038] The working principle of the above embodiment is:

[0039] The user places the marble slab on the support platform 2 so that one side edge of the marble slab is parallel to the grinder 47. The user then controls the second cylinder 51 to operate, and the output shaft of the second cylinder 51 drives the suction cup 53 to extend downward, so that the marble slab is clamped between the support platform 2 and the suction cup 53. Then, the user controls the first cylinder 3 to operate, and its output shaft drives the grinder 47 to fit one edge of the marble slab. Under the operation of the reciprocating motor 42, the grinder 47 is driven to completely grind the edge of the marble. Then, the user controls the rotation motor 23 to operate, and its output shaft can drive the second gear 24 to rotate, so that the first gear 22 can drive the positioning rod 21 and the support platform 2 and the marble slab placed on the support platform 2 to rotate in coordination with the rotation of the first gear 22, so that the other three edges of the marble slab can correspond to the grinder 47 respectively. The user controls the first cylinder 3 to operate again, and drives the grinder 47 to fit the other three edges of the marble slab and grind them respectively.
