[0026] See attached Figure 2 and attached Figure 6 Symmetrical sliding arms 202 are arranged on both sides of the moving seat 201 , and sliding grooves 104 cooperating with the sliding arms 202 are opened on the inner walls on both sides of the sliding cavity 103 ; a control panel 118 is also arranged on the support arm 107 .

[0027] In this embodiment, when the moving seat 201 slides back and forth along the sliding cavity 103, a sliding arm 202 structure is designed to further improve the stability during sliding. In order to further control the operation of the device, a control panel 118 structure is designed.

[0028] See attached Figure 6 -Attached Fig.10 A mounting cavity 207 is provided at the bottom of the hemming module 205, and a plurality of locking blocks 208 are arranged at intervals on the outer wall of the output end of the hemming motor 204, and a plurality of locking hoops 209 cooperating with the locking blocks 208 are arranged on the inner wall of the mounting cavity 207; a positioning ring 210 is also installed at the bottom of the hemming module 205, and the positioning ring 210 is sleeved on the output end of the hemming motor 204; a plurality of plug-in blocks 211 are arranged on the top of the positioning ring 210, and the plug-in blocks 211 are located between adjacent locking hoops 209; a plurality of locking bolts 212 are also threadedly installed on the positioning ring 210.

[0029] In this embodiment, in order to further improve the degree of freedom during the hemming operation, so as to replace the hemming module 205 of different specifications according to actual needs, a quick-release structure is designed. When installing the hemming module 205, firstly, the positioning ring 210 is sleeved on the output end of the hemming motor 204, and then the output end of the hemming motor 204 is installed in the installation cavity 207. Then, the hemming module 205 is rotated counterclockwise, and when the locking block 208 is inserted into the locking hoop 209, the positioning ring 210 is moved upward and the insert block 211 is inserted between the adjacent locking hoops 209, and finally, the positioning ring 210 is fixed to the bottom of the hemming module 205 by multiple sets of locking bolts 212.

[0031] In this embodiment: when the second hemming module 206 moves upward relative to the first hemming module 205 by adjusting the nut 217, the linkage convex ring 214 moves upward relative to the annular groove 213, and the distance between the second hemming module 206 and the first hemming module 205 increases, so the height of the hemming increases. When the second hemming module 206 moves downward relative to the first hemming module 205 by adjusting the nut 217, the linkage convex ring 214 moves downward relative to the annular groove 213, and the distance between the second hemming module 206 and the first hemming module 205 decreases, so the height of the hemming decreases.

[0032] See attached Fig.10 A limiting convex ring 219 is provided in the middle of the adjusting nut 217, and a limiting cavity 218 cooperating therewith is opened in the middle of the rotating hole 215.

[0033] In this embodiment: In order to ensure that the adjusting nut 217 can rotate freely relative to the hemming module 206, so as to facilitate further adjustment of the distance between the hemming module 1 205 and the hemming module 2 206, a matching limiting convex ring 219 and a limiting cavity 218 structure are designed.

[0034] See attached Fig.11 -Attached Fig.12A T-shaped slide groove 120 is provided on the sliding table 119, and a T-shaped seat 302 cooperating therewith is fixedly provided at the bottom of the sliding plate 301; a swing seat 303 and a limit frame 304 are also fixedly provided on the sliding plate 301, and the swing seat 303 is located on the outside of the limit frame 304; the linkage frame 305 is movably installed on the swing seat 303 through a swing arm 306; a driving shaft 311 is fixedly provided at one of the diagonal parts of the tripod 310, and a driven shaft 312 is fixedly provided in the middle of one group of side lengths of the tripod 310, and the driven shaft 312 is located on the opposite side of the driving shaft 311; the driven shaft 312 is slidably provided in the limit frame 304. An inclined positioning plate 313 is fixedly provided at the front end of the sliding plate 301, a grinding motor 314 is installed on the positioning plate 313, and a grinding disc 315 is installed at the output end of the grinding motor 314; a cantilever 316 is provided at the front end of the engaging frame 307, and a cleaning roller brush 317 is movably installed at the front end of the cantilever 316; a vertical plate 308 located on the side of the sliding plate 301 is also fixedly provided on the operating table 1, a swing motor 309 is installed on the vertical plate 308, and the output end of the swing motor 309 is connected to the driving shaft 311.

[0035] In this embodiment: when the swing motor 309 drives the tripod 310 to rotate freely relative to the meshing frame 307, since the tripod 310 is a triangular structure and the drive shaft 311 is located at a non-axial position of the tripod 310, when the tripod 310 rotates, the sliding plate 301 will reciprocate along the operating table 1, and the linkage frame 305 will also reciprocate relative to the swing seat 303. When the sliding plate 301 reciprocates, it can drive the front grinding motor 314 and the grinding disc 315 to intermittently grind the roll edge, and at this time, the cantilever 316 will also drive the front cleaning roller brush 317 to swing up and down while sliding back and forth, so as to reciprocate and scrape the edge of the steel plate. The movement trajectory of the cleaning roller brush 317 is relatively complex, which can be simplified to reciprocating sliding in the horizontal direction and reciprocating swinging relative to the swing seat 303.

[0036] See attached Figure 3 and attached Fig.11 A chip removal chamber 121 is provided on the operating table 1 below the grinding disc 315 and the cleaning roller brush 317 , a mounting frame 122 is provided at the bottom of the chip removal chamber 121 , a collecting bucket 123 is slidably installed in the mounting frame 122 , and a handle 124 is provided on the side wall of the collecting bucket 123 .

[0037] In this embodiment, after the cleaning roller brush 317 cleans the debris on the steel plate, the debris falls into the chip removal chamber 121. In order to facilitate the collection and cleaning of the debris, a collection bucket 123 structure is designed.

[0038] Working principle of the present invention: When the device is used, the steel plate to be rolled is first placed on the lower clamping plate 115 and the second air pump 116 is turned on. Then the clamping cylinder 108 is started to make the lifting seat 109 move downward. After the upper clamping plate 111 clamps the steel plate, the rotating motor 110 is started. When the upper clamping plate 111 and the lower clamping plate 115 drive the steel plate to be rolled to rotate, the regulating cylinders 106 on both sides are started to make the rolling mechanism 2 move closer to the middle. At this time, the steel plate can be rolled with the cooperation of the rolling module 1 205 and the rolling module 2 206. When the rolling is completed, the swing motor 309 is started again. When the swing motor 309 drives the tripod 310 to rotate freely relative to the engagement frame 307, the sliding plate 301 will reciprocate along the operating table 1, and the linkage frame 305 will also reciprocate relative to the swing seat 303. When the sliding plate 301 reciprocates, it can drive the grinding motor 314 and the grinding disc 315 at the front end to intermittently grind the edge of the roll, and at this time, the cantilever 316 will also drive the cleaning roller brush 317 at the front to swing up and down while sliding back and forth, so as to scrape and clean the edge of the steel plate. The flexible cleaning roller brush 317 moves the debris on the steel plate into the chip removal chamber 121.
