[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0026] This utility model provides a polishing device for cold-rolled stainless steel coils with a debris collection function. A protective box is installed on the top of the operating table, with inlet and outlet troughs on both sides of the protective box corresponding to the thickness and width of the stainless steel coil. A polishing roller is installed inside the protective box, and a fixing box is installed on the side wall of the protective box. Fan blades are installed inside the fixing box.

The protective box shields the debris generated during polishing, preventing it from flying and polluting the environment.

[0027] Example 1

[0028] Regarding the above-mentioned problem 1: During the polishing process of stainless steel coils, the friction between the polishing roller and the surface of the stainless steel coil will generate debris. Existing stainless steel coil polishing equipment is not convenient to collect the debris during polishing. The flying debris can easily pollute the environment and affect the health of workers.

[0029] The solution is as follows: This embodiment of a cold-rolled stainless steel coil polishing device with debris collection function includes an operating table 100 and a protective chamber 200.

[0030] Two electric take-up rollers 110 are installed on the top of the operating platform 100, respectively located at both ends of the top of the operating platform 100. Two auxiliary rollers 120 are symmetrically installed on the top of the operating platform 100, located between the two electric take-up rollers 110. The protective chamber 200 has an opening at the bottom of its inner cavity and is installed in the middle of the top of the operating platform 100. The protective chamber 200 has inlet and outlet troughs 210 on its symmetrical side walls. The inlet and outlet troughs 210 are at the same height as the auxiliary rollers 120, and are elongated and wide. The thickness of the stainless steel coil is 4mm greater than the thickness of the stainless steel coil. The height of the inlet / outlet chute 210 is 2mm greater than the thickness of the stainless steel coil. Multiple polishing rollers 220 are rotatably connected inside the protective chamber 200. The polishing rollers 220 are arranged in two groups, one above and one below the inlet / outlet chute 210. Each group of polishing rollers 220 consists of two rollers. Multiple first motors 230 are installed on the side wall of the protective chamber 200. The number of first motors 230 is the same as the number of polishing rollers 220, and the output of each first motor 230 corresponds to the number of polishing rollers 220. An observation window 240 is provided on the top of the protective chamber 200. The observation window 240 has a transparent glass interior. A fixing box 250 is installed on one side wall of the protective chamber 200. Two second motors 251 are symmetrically installed on the side wall of the fixing box 250. The two second motors 251 are located above and below the inlet / outlet chute 210, respectively. The output end of the second motor 251 extends into the fixing box 250 and is equipped with a rotating rod 252. A fan blade 253 is installed at the other end of the rotating rod 252. Not shown in the figure, in this embodiment, the first motor 230 and the second motor 251 are Z4-132 model DC motors. In the process, the first motor 230 of the upper and lower polishing rollers 220 rotates in opposite directions. When in use, the stainless steel coil passes through the inlet and outlet grooves 210 on both sides of the protective chamber 200 and passes through the inside of the protective chamber 200. The stainless steel coil is located between the upper and lower polishing rollers 220. At this time, the first motor 230 is started to drive the polishing rollers 220 to rotate and polish the upper and lower surfaces of the stainless steel coil. During the polishing process, the second motor 251 is started to drive the rotating rod 252 and the fan blade 253 to rotate. The upper and lower fan blades 253 rotate to generate airflow, which blows away the debris generated on the upper and lower surfaces of the stainless steel coil during polishing.

[0031] Example 2

[0032] Regarding the second problem to be solved above: When polishing stainless steel coils, some existing polishing devices use exhaust fans to suck out the generated debris, but during the exhaust process, some debris inevitably falls to the bottom, and it is difficult to remove this debris.

[0033] The solution is as follows: A cold-rolled stainless steel coil polishing device with debris collection function in this embodiment also includes a collection box 300 and a cleaning plate 400.

[0034] The operating console 100 has a slot 130 on its side wall and multiple through slots 140 on its top. Each through slot 140 is elongated and its bottom connects to the slot 130. All through slots 140 are located inside the protective compartment 200. A collection box 300 is located inside the slot 130. When the side wall of the collection box 300 abuts against the inner wall of the slot 130, the other side wall of the collection box 300 is flush with the side wall of the operating console 100. A collection slot 310 is located on the top of the collection box 300. A handle 320 is installed on the side wall of the collection box 300. A third motor 260 is installed near the bottom of the side wall of the protective compartment 200, with its output end extending into the protective compartment 200. A threaded rod 261 is installed inside the protective chamber 200. A guide rod 270 is installed at the same height as the threaded rod 261 inside the protective chamber 200. The threaded rod 261 and the guide rod 270 are symmetrically located inside the protective chamber 200. The cleaning plate 400 is located at the bottom of the protective chamber 200. Two push grooves 410 are opened on the symmetrical side walls of the cleaning plate 400. The push grooves 410 have inclined surfaces 411 at both ends inside, which slope inward. Threaded holes 420 are opened on the side walls of the cleaning plate 400. The threaded rod 261 rotates through the threaded holes 420. Guide holes 430 are also opened on the side walls of the cleaning plate 400. The guide rod 270 passes through the guide holes 430. The top of the side walls of the cleaning plate 400... A mounting plate 440 is installed above the threaded hole 420. The mounting plate 440 has an L-shaped structure, and an opening 450 is formed on the side wall of the vertical section of the mounting plate 440. The threaded rod 261 passes through the opening 450. A ring of bristles 451 is arranged around the inner wall of the opening 450. Not shown in the figure, in this embodiment, the third motor 260 is a Y2-160M-4 model three-phase asynchronous motor. During the polishing process, the debris blown off by the fan blade 253 falls on the top of the operating table 100. At this time, the third motor 260 is started to drive the threaded rod 261 to rotate. When the threaded rod 261 rotates, it uses a screw structure to push the cleaning plate 400 to move back and forth at the bottom of the protective box 200. During the movement, the debris located at the bottom of the protective box 200 on the moving side moves along the inclined surface 411 towards the center of the pusher trough 410 and gathers. When moving along the inclined surface 411, it falls into the slot 130 through the through slot 140 and into the collection trough 310. After polishing is completed, the handle 320 is pulled to pull the collection box 300 out of the slot 130 to process the debris inside the collection trough 310. At the same time, during the movement of the cleaning plate 400, the bristles 451 sweep away the debris on the surface of the threaded rod 261, which can prevent the debris from accumulating on the threaded surface of the threaded rod 261 and affecting the movement of the cleaning plate 400.

[0035] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
