[0065] The extension direction of the cleaning roller 232 is the same as that of the heated embossing roller 222. The front and rear ends of the cleaning roller 232 are rotatably connected to the inner side of the side plate 212. The front end of the cleaning roller 232 is fixedly connected to the upper synchronous pulley of the pulley component 231. Bristles are provided on the outer side of the cleaning roller 232. The front and rear ends of the scraper 233 are fixedly connected to the inner side of the side plate 212. The scraper 233 is located above the left side of the cleaning roller 232.

[0066] The cotton wool suction tube includes a three-way pipe 234 and a dust suction hose 235. The upper opening of the three-way pipe 234 is fixedly connected to the dust suction hose 235. The dust suction hose 235 is used to install a dust suction pump. The right opening of the three-way pipe 234 is located on the side of the scraper 233 away from the embossing component 22 and forms a cotton wool suction port. The lower opening of the three-way pipe 234 is a blocking structure.

[0067] The second driving assembly 24 is drivingly connected to the tee pipe 234 so that the tee pipe 234 moves back and forth along the length direction of the conveying gap.

[0068] The second driving assembly 24 includes a second motor 241 , a motor frame 242 , a sliding rod 243 , a first threaded rod 244 , a double-layer slip ring 245 and a connecting rod 246 .

[0069] The motor frame 242 is fixedly connected to the upper end of the bracket 1. The second motor 241 is fixedly connected to the rear end of the motor frame 242. The first threaded rod 244 extends in the same direction as the cleaning roller 232. The output end of the second motor 241 is fixedly connected to one end of the first threaded rod 244. The front and rear ends of the first threaded rod 244 are rotatably connected to the motor frame 242 and the sliding rod 243, respectively. The rear end of the sliding rod 243 is fixedly connected to the motor frame 242. The interior of the sliding rod 243 is hollow. The first threaded rod 244 is located within the sliding rod 243. The inner slip ring of the double-layer slip ring 245 is threadedly connected to the first threaded rod 244, and the outer slip ring of the double-layer slip ring 245 is slidably connected to the sliding rod 243. The lower end of the sliding rod 243 defines a slide groove. A connecting rod 246 is movably disposed within the slide groove. The right end of the outer slip ring of the double-layer slip ring 245 is fixedly connected to the connecting rod 246. The right end of the connecting rod 246 is fixedly connected to the bottom end of the tee pipe 234.

[0070] When the embossing device is in normal use, the first motor 211 and the second motor 241 are started, the first motor 211 drives the driving roller 213 to rotate, the driving roller 213 drives the lower gear 221 to rotate, the lower gear 221 engages to drive the upper gear 221 to rotate in the opposite direction, and the upper gear 221 drives the heated embossing roller 222 to rotate, so that the cotton strips continue to move under the rotation of the driving roller 213 and the heated embossing roller 222, and at the same time the heated embossing roller 222 embosses the cotton strips.

[0071] As the lower gear 221 rotates, it drives the lower synchronous wheel of the pulley component 231 to rotate. The lower synchronous wheel drives the upper synchronous wheel to rotate through the belt, and the upper synchronous wheel drives the cleaning roller 232 to rotate. The bristles on the cleaning roller 232 absorb the cotton wool remaining on the heated embossing roller 222. During the rotation of the cleaning roller 232, the absorbed cotton wool is scraped off by the scraper 233.

[0072] The second motor 241 drives the first threaded rod 244 to rotate. The rotation of the first threaded rod 244 causes the double-layer slip ring 245 to move along the slide rod 243. The double-layer slip ring 245 drives the connecting rod 246 to move. The connecting rod 246 drives the three-way pipe 234 to move. The three-way pipe 234 drives the dust suction hose 235 to make the dust suction hose 235 extend and retract. The three-way pipe 234 absorbs the cotton wool on the scraper 233 at one end facing the cleaning roller 232, so that the cotton wool or dust generated during the embossing process is absorbed and taken away, thereby preventing the cotton wool remaining on the embossing component 22 from affecting the embossing process and polluting the environment.

[0073] A guide device 3 is also installed on the bracket 1. The guide device 3 includes a guide assembly 31. The guide assembly 31 includes a guide roller 311 and a fixed frame 312. The fixed frame 312 is located on the side of the cleaning assembly 23 away from the embossing assembly 22. The fixed frame 312 is located above the bracket 1. Two guide rollers 311 are provided. The front and rear ends of the two guide rollers 311 are rotatably connected to the inner side of the fixed frame 312. The extension direction of the two guide rollers 311 is the same as the extension direction of the conveying gap. The height of the fixed frame 312 relative to the bracket 1 is adjustable.

[0074] The guide device 3 further includes an adjustment component 32 . The adjustment component 32 is located at the upper end of the bracket 1 and is connected to the guide component 31 to adjust the height of the fixing frame 312 relative to the bracket 1 .

[0075] The adjustment assembly 32 includes a slider 321 , a vertically arranged second threaded rod 322 , a vertically arranged directional rod 323 , a support frame 324 and a third motor 325 , wherein the second threaded rod 322 and the directional rod 323 are spaced apart along the axis direction of the guide roller 311 .

[0077] When the embossing device is in normal use and the height of the guide roller 311 needs to be adjusted, the third motor 325 is started, the third motor 325 drives the second threaded rod 322 to rotate, the second threaded rod 322 drives the front slider 321 to move up and down, the front slider 321 drives the fixed frame 312 to move, the fixed frame 312 drives the guide roller 311 and the rear slider 321 to move, the rear slider 321 limits the direction of the fixed frame 312, and the height of the guide roller 311 is adjusted by driving the third motor 325, so that the guide roller 311 can adapt to subsequent processing equipment of different heights.
