[0042] Working principle:

[0043] Supported stably by the base 11 in the main body structure 1, the steel strip in production passes through between the two guide rollers 15 at the left end of the base 11, passes through between the two guide rollers 15 at the right end of the base 11 for guiding and then is connected to the corresponding winding equipment to drive the steel strip to move; since the lifting block 13 can move up and down on the roller frame 12, and the lifting block 13 is supported upward by the spring 14, the distance between the two guide rollers 15 can be adjusted to use steel strips of different thicknesses.

[0044] Set the installation quantity of the electric slide rail 16 and the corresponding quantities of the scraper 32 assemblies 3 and the grinding assemblies 4 according to the corresponding processing requirements, and set the arrangement order of the scraper assemblies 3 and the grinding assemblies 4 from the left end to the right end of the base 11 according to the processing procedures. For example: the grinding assembly 4 does not install the sand cylinder 45, the scraper assembly 3, the grinding assembly 4 installs the sand cylinder 45, and the grinding assembly 4 does not install the sand cylinder 45; the processing sequence is to hold and limit the steel strip through the pressure roller 44 in the grinding assembly 4 for feeding, and then use the scraper 32 in the scraper assembly 3 to scrape the burrs on the side wall of the steel strip, and replace the corresponding scraper 32 according to the thickness and usage requirements of the steel strip, and then install the sand cylinder 45 with the help of the pressure roller 44 in the grinding assembly 4. At this time, the pressure roller 44 and the sand cylinder 45 adjust the relative inclination angle through the installation assembly 26, so that the sand cylinder 45 is inclined to contact the upper and lower edges of the side wall of the steel strip to grind the burrs and chamfer, and finally hold and guide again with the help of the pressure roller 44 in the grinding assembly 4;

[0045] During the processing, the electric slide rail 16 drives the limit structure 2 to move relatively, and adjusts according to the width of the steel strip; the first motor 23 drives the screw rods 22 at both ends of the limit frame 21 to rotate respectively, so as to drive the lifting seat 25 to be limited and lifted through the slide rod 24 and drive the installation assembly 26 to move up and down; the moving frame 261 in the installation assembly 26 is lifted and moved through screwing with the screw rod 22, and the moving frame 261 is butt-jointed with the lifting seat 25 through the adapter plate 5 to be stressed and lifted;

[0046] Two motors drive the two installation assemblies 26 to be driven separately to adjust the spacing to realize the processing of steel strips with different thicknesses and adjust the relative spacing of the turning table 262; the two ends of the tool holder 31 can be clamped between the slots 6 of the opposite turning tables 262 for clamping and installation, or the tool holder 31 can be inserted into only one turning table 262 for installation;
