[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figures 1 to 6 This utility model provides a technical solution: a heating roller scraper device, including a scraper body 1, an adjustment component 2 and an adaptive component 3; eight scraper bodies 1 are connected to the heating roller through the adjustment component 2, and the scraper bodies 1 are in contact with the roller surface of the heating roller.

[0027] The adjusting assembly 2 includes a U-shaped fixing frame 201, a rotating seat 202, a rotating shaft 203, a through-hole groove 204, an internal threaded sleeve 205, an external threaded rod 206, a guide groove 207, and a guide block 208. The U-shaped fixing frame 201 is fixedly connected to the support plate where the roller shaft of the heating roller is located. The rotating seat 202 is located inside the U-shaped fixing frame 201. One end of the rotating seat 202 is rotatably connected to one inner wall of the U-shaped fixing frame 201 through the rotating shaft 203, and the rotating seat 202 is connected to several scraper bodies 1 through the adaptive assembly 3. A through-hole groove 204 is provided on the other inner wall of the U-shaped fixing frame 201. The internal threaded sleeve 205 is slidably inserted into the through-hole groove 204. One end of the external threaded rod 206 is threaded through the internal threaded sleeve 205, and one end of the external threaded rod 206 is fixedly connected to the other end of the rotating seat 202. The number of scraper bodies 1 is eight.

[0028] Preferably, the external threaded rod 206 is threadedly connected to the internal threaded sleeve 205; the outer wall of the end face of the internal threaded sleeve 205 is an I-shaped structure, and the outer side of the inner end of the internal threaded sleeve 205 contacts the inner wall of the U-shaped fixing bracket 201; three guide grooves 207 are arranged in a ring array in the through hole groove 204; three guide blocks 208 are slidably inserted into the corresponding guide grooves 207, and the ends of the three guide blocks 208 are fixedly connected to the outer circumferential surface of the internal threaded sleeve 205.

[0029] This invention, through the setting of adjustment component 2, allows the external threaded rod 206 to rotate by rotating the handwheel on the external threaded rod 206, causing the rotating seat 202 to rotate via the rotating shaft 203 and the inner wall of the U-shaped fixing frame 201. Since the external threaded rod 206 is threadedly connected to the internal threaded sleeve 205, the internal threaded sleeve 205 slides within the through hole groove 204. Because the outer wall of the end face of the internal threaded sleeve 205 has an I-shaped structure, it prevents the internal threaded sleeve 205 from sliding out of the through hole groove 204, thereby limiting the rotation angle of the rotating seat 202. At the same time, the guide block 208 slides within the guide groove 207, allowing the scraper body 1 to contact the heating roller surface via the adaptive component 3. Compared with the prior art, this invention has a simple and reasonable structure and ingenious design. By adjusting the gap between the scraper body 1 and the roller surface, the effect of scraping off the powder skin by adhering to the heating roller surface can be guaranteed.

[0030] As a preferred embodiment, the adaptive component 3 includes a fixed base 301, a scraper receiving groove 302, a U-shaped slot 303, a horizontal sliding plate 304, and a vertical sliding plate 305. The fixed base 301 is fixedly mounted on the bottom side of the rotating base 202. A scraper receiving groove 302 is provided on the bottom side of one side of the fixed base 301. Several U-shaped slots 303 are linearly arrayed on the inner top wall of the scraper receiving groove 302. A horizontal sliding plate 304 is slidably mounted in the horizontal slot of each U-shaped slot 303. Two vertical sliding plates 305 are symmetrically slidably mounted in the two vertical slots of the U-shaped slot 303 through the moving component 4. The tops of several scraper bodies 1 are fixedly connected to the bottoms of the corresponding vertical sliding plates 305, and the tops of several scraper bodies 1 are all slidably engaged in the scraper receiving groove 302. Among them, the bottom ends of the horizontal sliding plate 304 are respectively set as two inclined surfaces A, and the top of the sides of the two vertical sliding plates 305 that are close to each other are respectively set as inclined surfaces B, and the inclined surfaces A and inclined surfaces B slide together.

[0031] The moving component 4 includes a moving groove 401 and a moving block 402; the inner walls of the two vertical grooves of the U-shaped hollow groove 303 are each provided with a moving groove 401; one end of the moving block 402 slides through the corresponding moving groove 401, and the other end of the moving block 402 is fixedly connected to the vertical sliding plate 305. When the side of the horizontal sliding plate 304 contacts the inner wall of the horizontal groove of the U-shaped hollow groove 303, the inclined surface A still contacts the inclined surface B, and the bottom surface of the moving block 402 contacts the bottom wall of the moving groove 401.

[0032] This invention, by setting an adaptive component 3 and a moving component 4, allows the scraper body 1, where one of the vertical slide plates 305 within the U-shaped groove 303 is located, to slide within the scraper receiving groove 302 when it contacts the heating roller surface. This causes the vertical slide plate 305 to slide within the vertical groove of the U-shaped groove 303, and the moving block 402 to slide within the moving groove 401. This causes the inclined surface B on the vertical slide plate 305 to press against the inclined surface A at one end of the horizontal slide plate 304, causing the horizontal slide plate 304 to slide within the horizontal groove of the U-shaped groove 303. Meanwhile, the horizontal slide plate 304... The inclined surface A at the other end presses against the inclined surface B on another vertical slide plate 305, causing the other vertical slide plate 305 to slide in another vertical groove of the U-shaped slot 303, causing the moving block 402 on the same side to slide in the moving groove 401, and causing the scraper body 1 connected to the other vertical slide plate 305 to slide in the scraper receiving groove 302, so that the two scraper bodies 1 slide in opposite directions in the scraper receiving groove 302 until the other scraper body 1 contacts the heating roller surface. Throughout the process, the scraper body 1 and the roller surface can adaptively adjust their final positions.

[0033] Working principle: In use, firstly, by rotating the handwheel on the external threaded rod 206, the external threaded rod 206 is activated. Since the external threaded rod 206 is threadedly connected to the internal threaded sleeve 205, the internal threaded sleeve 205 slides in the through-hole groove 204, causing the guide block 208 to slide in the guide groove 207, until the scraper body 1 connected to one of the vertical slide plates 305 in the U-shaped hollow groove 303 contacts the heating roller surface. At this time, the scraper body 1 will slide in the scraper receiving groove 302, causing the vertical slide plate 305 to slide in one of the vertical grooves of the U-shaped hollow groove 303, causing the moving block 402 to slide in the moving groove 401, causing the inclined surface B on the vertical slide plate 305 to press against the horizontal slide plate. One end of plate 304 has an inclined surface A, which causes the horizontal slide plate 304 to slide in the horizontal groove of the U-shaped slot 303. The other end of the horizontal slide plate 304 has an inclined surface A, which presses against the inclined surface B on another vertical slide plate 305, causing the other vertical slide plate 305 to slide in another vertical groove of the U-shaped slot 303. The moving block 402 on the same side slides in the moving groove 401, and the scraper body 1 connected to the other vertical slide plate 305 slides in the scraper receiving groove 302. The two scraper bodies 1 slide in opposite directions in the scraper receiving groove 302 until the other scraper body 1 contacts the surface of the heating roller. Throughout the process, the scraper body 1 and the roller surface can be adaptively adjusted to their final positions.

[0034] The above is the entire working process of the device, and all contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
