Description

[Technical field]

[0001] The invention relates to the technical field of stone processing equipment, and in particular to a polishing device and a polishing method. [Background technology]

[0002] Curbstones are generally used as boundary stones on the edge of the road. They are the boundaries that distinguish the carriageway, sidewalk, green space, isolation belt and other parts of the road on the road surface, and play a role in ensuring the safety of pedestrians and vehicles and ensuring the neatness of the road edge.

[0003] During the production process of curbstones, the surface of the curbstones needs to be polished; for example, the Chinese invention patent with application number CN202211192430.9 discloses an automated curbstone processing device and its use method, and the Chinese invention patent with application number CN202411132093.3 discloses a curbstone thickness-fixed polishing assembly line process. Of course, some curbstones also have a rounded surface. In order to meet the polishing requirements of the rounded surface, the prior art usually uses a reciprocating swing mechanism to drive the polishing wheel to swing back and forth to meet the polishing requirements of the rounded surface.

[0004] In order to make the curbstone more beautiful, the curbstone with inclined surface appeared. Figure 1 As shown, there is a slope 101' at the upper right of the curbstone 100', and both the upper and lower ends of the slope 101' are formed with rounded corners 102' for achieving transition. Due to the limitation of the slope 101', the existing polishing structure can no longer meet the polishing requirements of the two rounded corners 102' of the curbstone with the slope 101'. Therefore, it is urgent to provide a polishing device that can realize automatic polishing of the two rounded corners of the curbstone with the slope. [Summary of the invention]

[0073] The polishing device 100 of the present invention can achieve five aspects of adjustment during specific use: the first aspect is to use the horizontal adjustment component 261 of the position adjustment mechanism 26 to drive the mounting plate 28 and the sanding belt 21, the driving wheel 22, the first driven wheel 23, and the second driven wheel 24 to adjust the horizontal position as a whole; the second aspect is to use the vertical adjustment component 262 of the position adjustment mechanism 26 to drive the mounting plate 28 and the sanding belt 21, the driving wheel 22, the first driven wheel 23, and the second driven wheel 24 to adjust the vertical height position as a whole; the third aspect is to use the rotation adjustment component 263 of the position adjustment mechanism 26 to drive The movable mounting plate 28 and the sanding belt 21, the driving wheel 22, the first driven wheel 23, and the second driven wheel 24 are rotated and adjusted as a whole; the fourth aspect is to use the second driving mechanism 29 to drive the mounting plate 28 and the sanding belt 21, the driving wheel 22, the first driven wheel 23, and the second driven wheel 24 to slide as a whole; the fifth aspect is to use the adjustment plate 41 and the rocker rod 42 to drive the first driven wheel 23 and the second driven wheel 24 to adjust their positions. Through the above five aspects of adjustment, the polishing section 211 formed between the first driven wheel 23 and the second driven wheel 24 can well adapt to the polishing processing requirements of different radiused surfaces of the curbstone.

[0074] In some embodiments of the present invention, the polishing device 100 further includes a brush 51, a brush driving mechanism 52 and a finishing mechanism 6;

[0075] The finishing mechanism 6 is arranged on the conveyor 1 and is located on a side away from the abrasive belt polisher 2. When working, the finishing mechanism 6 can be used to sort the curbstones entering the conveyor 1, so that the abrasive belt polisher 2 can better polish the curbstones; the brush 51 is arranged at the output end of the conveyor 1, and the brush 51 and the abrasive belt polisher 2 are located on the same side, so that the brush 51 can clean the polishing position of the curbstone; the brush driving mechanism 52 is connected to the brush 51, and the brush driving mechanism 52 drives the brush 51 to adjust so that the brush 51 contacts the polishing surface of the stone (i.e., the curbstone). In the specific implementation of the present invention, the brush driving mechanism 52 can use a screw motor. When working, the brush driving mechanism 52 can be used to drive the brush 51 close to the stone, so that the stone can contact the brush 51 when output, so that the brush 51 can be used to clean the polishing surface of the stone.

[0076] As a specific embodiment of the present invention, the sorting mechanism 6 includes a sorting block 61 and a sorting drive assembly 62 that drives the sorting block 61 to move along the width direction of the conveyor 1. During operation, when the stone enters the conveyor 1, the sorting drive assembly 62 can be used to drive the sorting block 61 to move, so that the sorting block 61 can sort the stone, thereby ensuring that the belt polisher 2 can accurately polish the rounded corners of the stone.

[0077] Embodiment 2

[0078] Please refer to Figures 2 to 11 As shown, the present invention provides a polishing method for a polishing device, wherein the specific structure of the polishing device is exactly the same as that of the first embodiment. For details, please refer to the detailed introduction of the first embodiment, which will not be repeated here; the polishing method comprises the following steps:

[0079] Step S1, using the position adjustment mechanism 26 of each belt polisher 2 to drive the mounting plate 28, the belt 21, the driving wheel 22, the first driven wheel 23 and the second driven wheel 24 to adjust the position together, so that the belt 21 of each belt polisher 2 is directed toward the rounded corner surface of the stone (i.e., the rounded corner surface of the curbstone); because the curbstone with an inclined surface has two rounded corner surfaces, and the present invention is provided with multiple belt polishers 2 on either side of the conveyor 1, the belt 21 of each belt polisher 2 can be adjusted by the position adjustment mechanism 26, and the belt 21 of one part of the belt polishers 2 is aligned with one of the rounded corner surfaces of the curbstone, and the belt 21 of another part of the belt polishers 2 is aligned with the other rounded corner surface of the curbstone. At the same time, when the present invention is implemented, the first driven wheel 23 and the second driven wheel 24 can be adjusted by using the adjustment plate 41 and the rocker rod 42 according to the rounded surface of the actual stone, so that the polishing section 211 between the first driven wheel 23 and the second driven wheel 24 can better adapt to the rounded surface of the stone.

[0080] Step S2, when the conveyor 1 conveys the stone to the corresponding workstation, the second driving mechanism 29 of the belt polisher 2 at the workstation is controlled to drive the mounting plate 28 to drive the sanding belt 21, the driving wheel 22, the first driven wheel 23 and the second driven wheel 24 to move together, and the sanding belt 21 is in contact with the rounded corner surface of the stone; the first driving mechanism 27 is controlled to drive the driving wheel 22 to drive the sanding belt 21 to transmit, so that the sanding belt 21 polishes the rounded corner surface of the stone; when the present invention is implemented, after the stone enters the conveyor 1, the finishing mechanism 6 can be used to first finish the stone to ensure that the belt polisher 2 can polish the stone.

[0081] Step S3, conveying the stone polished by each belt polisher 2 to the next process through the conveyor 1; in the specific implementation of the present invention, since multiple belt polishers 2 are arranged on any side of the conveyor 1, it is necessary to wait until each belt polisher 2 completes the polishing operation of the stone before conveying the polished stone to the next process.
