[0003] In the process of producing curbstones, it is necessary to determine the thickness and polish the surface of the curbstones. In order to improve the production efficiency of curbstones, there are some production lines in the prior art that can automatically process curbstones, such as an automated curbstone processing device and its use method disclosed in the Chinese invention patent application number CN202211192430.9. However, in some applications, it is necessary to use curbstones with inclined surfaces, such as Fig.14 As shown, there is a slope 101' on the upper right side of the kerbstone 100', and both the upper and lower ends of the slope 101' are formed with rounded corners 102' for transition, and a side surface 103' is left below the slope 101'. Obviously, the existing production line can no longer meet the demand for automated production of kerbstones with slopes. In view of the above problems, the inventor of this case conducted in-depth research on the problem, and thus this case was created. [Summary of the invention]

[0072] Embodiment 2

[0073] See also Figures 1 to 13 As shown, a processing method of a kerbstone processing line of the present invention, wherein the specific structure of the kerbstone processing line and the technical effects that can be obtained are exactly the same as those of the first embodiment. Please refer to the detailed introduction of the first embodiment for details, which will not be repeated here; the processing method comprises the following steps:

[0074] Step S1, loading the curbstones by the loading machine 1, with the bottom surface of the curbstones facing upwards, and conveying the curbstones to the first wire drawing and thickness calibrating machine 2;

[0075] Step S2, drawing and thickness setting the bottom surface of the curbstone by the first drawing and thickness setting machine 2, and conveying the drawn and thickness-setting curbstone to the turning machine 3; since the top surface of the curbstone needs to be polished and other operations are required later, drawing and thickness setting the bottom surface of the curbstone first can facilitate subsequent processing operations;

[0076] Step S3, turning the kerbstone 180° by the turning machine 3 so that the top surface of the kerbstone faces upward, and conveying the turned kerbstone to the second wire drawing and thickness calibration machine 4;

[0077] Step S4, drawing and thickness setting the top surface of the curbstone by the second drawing and thickness setting machine 4, and conveying the drawn and thickness set curbstone to the molding machine 5;

[0078] Step S5, the side surface and the inclined surface below the inclined surface of the curb stone are calibrated by the molding machine 5, and the two rounded surfaces at the upper and lower ends of the inclined surface of the curb stone are shaped by the molding machine 5, and the shaped curb stone is conveyed to the polishing machine 6; when the present invention is specifically implemented, the molding machine 5 will first grind and calibrate the side surface below the inclined surface of the curb stone, then grind and calibrate the inclined surface of the curb stone, and finally process and shape the two rounded surfaces of the curb stone;

[0079] Step S6, polishing the bevel below the bevel of the curbstone, the side surface and the top surface by the polishing machine 6, and conveying the polished curbstone to the sanding machine 7; in the specific implementation of the present invention, the polishing machine 6 will first polish the bevel of the curbstone, then polish the side surface of the curbstone, and finally polish the top surface of the curbstone;

[0080] Step S7, polish the two rounded surfaces of the curbstone by the sanding machine 7, and convey the polished curbstone to the stacker 8, which stacks the processed curbstone; in the specific implementation of the present invention, before polishing the rounded surface of the curbstone by the sanding machine 7, the sanding belt adjustment mechanism 74 and the driven wheel adjustment mechanism 75 can be used to adjust the sanding belt 72 first, so that the polishing section 721 of the sanding belt 72 is adapted to and fully in contact with the rounded surface of the curbstone, thereby ensuring that the polishing section 721 of the sanding belt 72 can reliably polish the rounded surface during the transmission of the sanding belt 72.

[0081] Although the specific implementation modes of the present invention are described above, those skilled in the art should understand that the specific implementation modes described are only illustrative and are not intended to limit the scope of the present invention. Equivalent modifications and changes made by those skilled in the art in accordance with the spirit of the present invention should be included in the scope of protection of the claims of the present invention.
