[0027] In this embodiment, as Figure 1 and Figure 3 shown, the replacement path assembly includes a path conversion motor 301. The path conversion motor 301 is fixed to the rear end of the frame 100 through a first fixing bracket 302. The output end of the path conversion motor 301 is fixedly connected to a fixing plate 303 at the front end of the frame 100. Two first turning shafts 304, two second turning shafts 305, a first paper inlet plate 306, and a second paper inlet plate 307 are respectively fixed to the front end of the fixing plate 303. A paper outlet plate 308 is fixed to the front end of the frame 100. The paper outlet plate 308 is located at the right end of the first paper inlet plate 306. The upper end of the paper outlet plate 308 is on the same horizontal plane as the upper end of the first paper inlet plate 306. Fixing components are provided at the upper ends of the first paper inlet plate 306, the second paper inlet plate 307, and the paper outlet plate 308. The transfer paper on the first transfer paper roll rod 201 is laid flat on the upper end of the first paper inlet plate 306 from the first paper outlet turning shaft 203 through the two first turning shafts 304. The transfer paper on the second transfer paper roll rod 202 is laid flat on the upper end of the second paper inlet plate 307 from the second paper outlet turning shaft 204 through the two second turning shafts 305. When one paper roll is almost used up, the path conversion motor 301 rotates to change the paper roll supply path.

[0028] In one embodiment, as Figure 5As shown, the fixing component includes four fixing columns 401. The upper ends of the four fixing columns 401 are fixed with a connecting plate 402. The lower end of the connecting plate 402 is fixed with a first telescopic cylinder 403. The output end of the first telescopic cylinder 403 is fixed with a pressing paper board 404.

The cutting blade 504 is located between the first paper feeding board 306 and the paper output board 308. When the second telescopic cylinder 501 extends its output shaft, it drives the cutting blade fixing block 503 to move between the first paper feeding board 306 and the paper output board 308, and the cutting blade 504 cuts the transfer paper to facilitate the replacement of the path.

[0030] In one embodiment, as Figure 1 shown, the sticker module includes a rotating motor 601. The rotating motor 601 is fixed to the rear end of the frame 100 through a third fixing bracket 602. The output shaft of the rotating motor 601 is fixed with a sticker arm 603 at the front end of the frame 100. An absorbing paper cavity 604 is fixed on the sticker arm 603. A group of air suction holes are provided on the absorbing paper cavity 604. The absorbing paper cavity 604 is communicated with a negative pressure pump 605 through an air pipe. The negative pressure pump 605 is fixed to the upper end of the third fixing bracket 602. After the path is replaced, the rotating motor 601 rotates, and the tape sucked by the absorbing paper cavity 604 is pasted on the gap of the transfer paper. The negative pressure pump 605 stops sucking air, releases the tape, and the rotating motor 601 rotates back to complete the connection of the transfer paper.

[0031] In one embodiment, as Figure 1 shown, the detection component includes two distance sensors 701. The distance sensors 701 are fixed to the front end of the frame 100 through sensor fixing rods 702.

[0034] The above embodiment discloses a transfer paper changing mechanism, in which two transfer paper rolls are respectively fixed on the first transfer paper roll rod 201 and the second transfer paper roll rod 202. The transfer paper on the first transfer paper roll rod 201 is laid flat on the upper end of the first paper feeding board 306 from the first paper output steering shaft 203 via two first steering shafts 304. The transfer paper on the second transfer paper roll rod 202 is laid flat on the upper end of the second paper feeding board 307 from the second paper output steering shaft 204 via two second steering shafts 305. When the transfer paper on the first transfer paper roll rod 201 is supplied, the transfer paper on the second transfer paper roll rod 203 is fixed on the upper end of the second paper feeding board 307 by the pressing paper board 404. When the transfer paper on the first transfer paper roll rod 201 is almost used up, the pressing paper board 404 fixes the transfer paper on the upper ends of the first paper feeding board 306 and the paper output board 308. The telescopic cylinder two 501 extends the output shaft, driving the cutting blade fixing block 503 to move between the first paper feeding board 306 and the paper output board 308, and the cutting blade 504 cuts the transfer paper. The path conversion motor 301 rotates to rotate the second paper feeding board 307 to the position of the paper output board 308. The rotation motor 601 rotates to stick the tape sucked through the paper suction cavity 604 to the gap of the transfer paper. The negative pressure pump 605 stops sucking air to release the tape. The rotation motor 601 rotates back to complete the connection of the transfer paper. The pressing paper board 404 releases the transfer paper at the second paper feeding board 307 and the paper output board 308 to complete the replacement of the paper roll.
