[0048] Reference Figure 6 and Figure 7 , the moving screw rod 223 is driven to rotate by the driving motor 222, thereby driving the slider 224 to move along the axial direction of the tension roller 211, so that the slider 224 drives the cleaning knife 221 to clean the surface of the tension roller 211 along the side wall of the tension roller 211, and the cleaned impurities are blocked by the baffle 226 and fall into the collection box 227 that moves with the slider 224 along the side wall of the baffle 226. After the cleaning is completed, the unlocking ring 2212 is pushed toward the mounting block, so that the push block 2213 on the unlocking ring 2212 contacts the arc surface of the limit block 229 and moves along the arc surface of the limit block 229, thereby pushing the limit block 229 to move toward the axial direction of the quick release rod 228, so that the limit block 229 is separated from the limit groove 2211, so that the quick release rod 228 and the quick release sleeve 2210 are separated, thereby realizing the disassembly of the collection box 227. After the collection box 227 is disassembled, the unlocking ring 2212 is loosened, and the unlocking ring 2212 is reset under the action of the unlocking spring 2214, so that the collection box 227 can be reinstalled on the quick-release rod 228.

[0049] Reference Figure 8The cleaning mechanism 22 also includes an avoidance component, which includes an avoidance guide rail 2215 and an avoidance wedge 2216. A waist-shaped hole 2131 for sliding the rotating shaft of the tensioning roller 211 is opened on the adjusting plate 213 at the rotating shaft of the tensioning roller 211. The end of the tensioning roller 211 is rotatably connected with a mounting plate 2218, and the mounting plate 2218 is slidably connected to the adjusting plate 213. A sliding rod 2220 is fixedly installed on the side wall of one side of the mounting plate 2218. The axis of the sliding rod 2220 is parallel to the axis of the waist-shaped hole 2131. A supporting plate is fixedly installed on the side wall of the adjusting plate 213. The sliding rod 2220 passes through the supporting plate and is slidably connected to the supporting plate. An avoidance spring 2217 is sleeved on the sliding rod 2220. One end of the avoidance spring 2217 conflicts with the side wall of the mounting plate 2218, and the other end conflicts with the side wall of the support plate. The avoidance guide rail 2215 is arranged along the axis direction of the tensioning roller 211, and the mounting plate 2218 is fixedly connected to the end of the avoidance guide rail 2215 through the folding rod 2221. The middle part of the avoidance guide rail 2215 protrudes toward the slider 224, and the length of the protruding part is equal to the length of the tensioning roller 211. The avoidance wedge block 2216 is fixedly installed on the slider 224, and the avoidance wedge block 2216 conflicts with the protruding part of the avoidance guide rail 2215. The distance between the protruding part of the avoidance guide rail 2215 and the slider 224 is greater than the length of the avoidance wedge block 2216.

[0050] Reference Figure 8When the slider 224 slides along the moving screw rod 223, the slider 224 drives the avoidance wedge 2216 to move, so that the inclined surface of the avoidance wedge 2216 contacts the side wall of the raised part of the avoidance guide rail 2215, and pushes the avoidance guide rail 2215 away from the slider 224, so that the avoidance guide rail 2215 drives the mounting plate 2218 to move and compress the avoidance spring 2217 through the folding rod 2221, so that the mounting plate 2218 drives the tensioning roller 211 to slide along the waist-shaped hole 2131, so that the distance between the multiple tensioning rollers 211 is expanded, thereby reducing the cleaning knife 22 When cleaning the surface of the tension roller 211, the cleaning knife 221 interferes with the other tension roller 211, and the tension roller 211 drives the cleaning knife 221 to move, so that the cleaning knife 221 drives the mounting rod 2219 to slide on the slider 224, so that the cleaning knife 221 and the surface of the tension roller 211 are kept in contact, and as the cleaning knife 221 cleans the surface of the tension roller 211, the end of the avoidance wedge 2216 keeps contacting the protruding part of the avoidance guide rail 2215, so that the avoidance guide rail 2215 drives the tension roller 211 to always keep it separated from the other tension roller 211. When cleaning is completed and the cleaning knife 221 returns to its initial position, the raised portion of the avoidance guide rail 2215 separates from the end of the avoidance wedge 2216. At this time, the mounting plate 2218 is reset under the action of the avoidance spring 2217, thereby driving the avoidance guide rail 2215 and the tensioning roller 211 to reset, so that the side wall of the raised portion of the avoidance guide rail 2215 fits again with the inclined surface of the avoidance wedge 2216 to facilitate the next cleaning.

[0051] Reference Figure 2 The heating device 3 includes an electric heating plate 31, which is fixedly installed in the furnace body 1, and there are several electric heating plates 31, which are arranged along the travel path of the strip, and the electric heating plates 31 are arranged above and below the travel path of the strip.

[0052] Reference Figure 2 A suspension device 4 is also installed on the furnace body 1. The suspension device 4 includes an electromagnet 41. The electromagnet 41 is fixedly installed on the side wall of the furnace body 1, and the side walls on both sides of the furnace body 1 are provided with electromagnets 41. A gap is left between the electromagnets 41 on both sides of the furnace body 1 for the strip to pass through.

[0053] The working principle of the embodiment of the present application is as follows: the strip is conveyed into the furnace body 1, and the strip is tensioned by the tensioning mechanism 21 at both ends of the furnace body 1. When the strip is tensioned, the locking nut 214 is adjusted so that the adjusting screw 212 drives the adjusting plate 213 to move, thereby driving the tensioning roller 211 to move, thereby adjusting the tension of the strip. Then, the electromagnet 41 in the suspension device 4 is energized, so that the strip between the tensioning mechanism 21 at both ends of the furnace body 1 is suspended, thereby reducing the sagging of the strip in the furnace body 1 due to the influence of gravity. Then, the electric heating plate 31 is energized to heat the strip.

[0054] When the strip needs to be cleaned of impurities adsorbed on the surface of the tensioning roller 211 after heat treatment, the cleaning mechanism 22 starts working and starts the driving motor 222, thereby driving the movable screw 223 to rotate, thereby driving the slider 224 to move in a direction parallel to the axis of the tensioning roller 211, thereby driving the cleaning knife 221 to scrape off the impurities on the surface of the tensioning roller 211, and the impurities fall into the collection box 227 that moves with the slider 224 under the action of the baffle 226. At the same time, the slider 224 drives the avoidance wedge 2216 to move, so that the avoidance wedge 2216 pushes the raised part of the avoidance guide rail 2215, so that the avoidance guide rail 2215 drives the mounting plate 2218 to move and compress the avoidance spring 2217 through the folding rod 2221, so that the rotating shaft of the tensioning roller 211 moves in the waist-shaped hole 2131, so that the tensioning roller 211 is away from other tensioning rollers 211, thereby reducing the interference of the cleaning knife 221 on the tensioning roller 211 with other tensioning rollers 211, and as the slider 224 moves, the end of the avoidance wedge 2216 keeps contacting the raised part of the avoidance guide rail 2215, so that the tensioning roller 211 keeps away from other tensioning rollers 211.

[0055] When the cleaning is completed, the slider 224 returns to its initial position, and the end of the avoidance wedge 2216 separates from the raised portion of the avoidance guide rail 2215, so that the mounting plate 2218 is reset under the action of the avoidance spring 2217, thereby driving the avoidance guide rail 2215 and the tensioning roller 211 to tension the strip again.

[0056] Subsequently, by pushing the unlocking ring 2212 in the direction of the slider 224, the push block 2213 on the unlocking ring 2212 pushes the limit block 229 in the axial direction of the quick release rod 228, so that the limit block 229 is separated from the limit groove 2211, so that the quick release rod 228 and the quick release sleeve 2210 are separated, so that the collection box 227 can be easily removed to clean the impurities in the collection box 227. After the collection box 227 is cleaned, the quick release sleeve 2210 is re-mounted on the quick release rod 228, so that the limit block 229 is engaged with the limit groove 2211, so as to limit the quick release sleeve 2210, so as to continue to collect impurities.

[0057] The above are preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
