[0065] The working principle of this embodiment is as follows: (1) Coating liquid: The food flows into the first blanking cylinder 412 and the second material receiving cylinder 417 through the feeding bin 1. The first motor 402 is started, and the output shaft of the first motor 402 drives the first connecting shaft 408 to rotate. The first pulley 407 on the first connecting shaft 408 drives the second pulley 410 to rotate through the first belt 409. The second pulley 410 drives the second connecting shaft 411 to rotate. The first clamping groove 427 on the second connecting shaft 411 is clamped with the third convex block 449, thereby driving the second connecting ring 423 and the fourth connecting ring 426 to rotate. The second connecting ring 423 drives the first connecting ring 422 to rotate, and the fourth connecting ring 426 drives the third connecting ring 425 to rotate. The first convex blocks 428 on the outer circumferences of the first connecting ring 422 and the third connecting ring 425 are respectively clamped with the second clamping grooves 429 on the inner circumferences of the first connecting cylinder 414 and the second connecting cylinder 416 and drive the first connecting cylinder 414 and the second connecting cylinder 416 to rotate respectively. The first connecting cylinder 414 drives the first blanking cylinder 412 to rotate, and the second connecting cylinder 416 drives the second material receiving cylinder 417 to rotate. When the first blanking hole 413 on the first blanking cylinder 412 communicates with one of the fourth pipelines 11, and the second material receiving hole 418 on the second material receiving cylinder 417 communicates with the other fourth pipeline 11, the food in the first blanking cylinder 412 and the second material receiving cylinder 417 respectively flows into the coating liquid cylinder 404 through the fourth pipeline 11.

[0066] The coating liquid enters the coating liquid cylinder 404 through the liquid inlet pipe 446. The first communication pipe 403 is used for exhausting air. The rotation of the first connecting shaft 408 drives the second gear 433 to rotate. The second gear 433 drives the gear ring 432 to rotate through the first gear 430. The gear ring 432 drives the first outer cylinder 435 to rotate. The rotation direction of the first outer cylinder 435 is opposite to the rotation direction of the sleeve shaft 442. The first stirring blade 440 and the fishing blade 441 on the first outer cylinder 435 rotate respectively. The first stirring blade 440 is used for stirring the coating liquid and evenly coating the coating liquid on the food. The fishing blade 441 fishes up the food wrapped with the coating liquid. When the third blanking hole 438 on the first outer cylinder 435 rotates to communicate with the second blanking hole 437 on the inner cylinder 434, when the food passes through the third blanking hole 438 and the second blanking hole 437, it falls into the inside of the inner cylinder 434. While the first connecting shaft 408 rotates, the second convex block 445 on the first connecting shaft 408 is clamped with the third clamping groove 443 on the sleeve shaft 442 and drives the sleeve shaft 442 to rotate. The spiral blade 444 on the sleeve shaft 442 rotates, and the spiral blade 444 transports the food after coating through the first pipeline 8 to the second outer cylinder 501 for coating and drying.

[0067] When one of the wrapping components needs to be cleaned: Start the second motor 420. The output shaft of the second motor 420 drives the first lead screw 419 to rotate. The first connecting rod 415 moves on the first lead screw 419. The first lead screw 419 drives the second connecting ring 423 and the fourth connecting ring 426 to move horizontally. The third bumps 449 on the second connecting ring 423 and the fourth connecting ring 426 slide on the first card slots 427 on the second connecting shaft 411. The teeth of the second connecting ring 423 mesh with the teeth of the first connecting ring 422 for transmission. The first bumps 428 on the outer circumference of the first connecting ring 422 are respectively clamped with the second card slots 429 on the inner circumference of the first connecting cylinder 414 and drive the first connecting cylinder 414 to rotate. The first connecting cylinder 414 drives the first blanking cylinder 412 to rotate. The teeth of the fourth connecting ring 426 are separated from the teeth of the third connecting ring 425. The third connecting ring 425 no longer drives the second connecting cylinder 416 to rotate. The second connecting cylinder 416 no longer drives the second feeding cylinder 417 to rotate. The food in the second feeding cylinder 417 no longer enters one of the coating cylinders 404 through the second feeding hole 418. Clear water enters the coating cylinder 404 through the liquid inlet pipe 446 to clean the inside of one of the coating cylinders 404. After cleaning, open the valve on the fifth pipe 405. The cleaned water flows into the liquid storage cylinder 406 through the fifth pipe 405. When it is necessary to clean the other coating cylinder 404, reverse the second motor 420, with the same working principle as above.

[0068] (2) Drying: Add coating powder into the inlet bin 2. The coating powder flows into the fifth connecting ring 519 through the third pipe 10 and enters the drying cylinder 511. The coating powder enters the inside of the drying cylinder 511 through the fourth through holes 517 of the drying cylinder 511. The food enters the inside of the rotating cylinder 510 from the second outer cylinder 501.

[0069] Start the third motor 507. The output shaft of the third motor 507 drives the fourth connecting shaft 521 to rotate. When the fourth connecting shaft 521 rotates clockwise, since the ratchet 523 on the fourth connecting shaft 521 is not engaged with the pawl 522, it will not drive the third pulley 506 to rotate. The fourth connecting shaft 521 drives the third connecting shaft 518 to rotate through the universal joint 509. The sixth gear 515 on the third connecting shaft 518 rotates. The sixth gear 515 drives the fourth gear 513 to rotate through the fifth gear 514. The fourth gear 513 drives the third gear 512 to rotate. The third gear 512 drives the seventh gear 516 to rotate. The seventh gear 516 drives the rotating cylinder 510 to rotate. The rotation direction of the rotating cylinder 510 is opposite to that of the third connecting shaft 518. During the rotation of the third connecting shaft 518, the second stirring blade 520 on the third connecting shaft 518 is used to disperse the coating powder. The dispersed coating powder enters the rotating cylinder 510 through the fourth through hole 517 of the drying cylinder 511. The coating powder evenly wraps the food. The negative pressure cylinder 503 sends gas into the second outer cylinder 501 through the second connecting pipe 502 to dry the coating powder wrapped on the food.

[0070] Adjusting the angle of the second outer cylinder 501 can better wrap the coating powder on the food: When the third motor 507 rotates in reverse and the fourth connecting shaft 521 rotates counterclockwise, since the ratchet 523 on the fourth connecting shaft 521 is engaged with the pawl 522, it drives the third pulley 506 to rotate. The third pulley 506 drives the fourth pulley 725 to rotate through the second belt 508. The fourth pulley 725 drives the shaft of the eighth gear 708 to rotate. The eighth gear 708 drives the first sleeve 717 to rotate. The first sleeve 717 drives the fifth connecting shaft 720 to rotate. Since the fifth protrusion 721 on the fifth connecting shaft 720 is engaged with the fourth card slot 723 in the circumferential direction inside the second lead screw 716 and drives the second lead screw 716 to rotate, the slider 707 slides on the second lead screw 716. The second lead screw 716 drives the two third connecting rods 712 to horizontally move in the first sliding holes 705 on the first fixing plate 704 respectively. The two third connecting rods 712 drive the fourth connecting rods 713 to move respectively. The fourth connecting rod 713 drives the sliding rod 714 to slide in the second sliding hole 706 of the second fixing plate 715. The sliding rod 714 drives the second outer cylinder 501 to rotate, so as to achieve the purpose of adjusting the angle of the second outer cylinder 501.

[0071] When the second lead screw 716 needs to rotate in the reverse direction, rotate the handle 710. The handle 710 drives the second sleeve 718 to rotate. The fourth convex block 719 on the second sleeve 718 slides in the chute 722 of the fifth support frame 701. The second sleeve 718 abuts against the second baffle 724 and drives the fifth connecting shaft 720 to move horizontally through the second baffle 724. The first sleeve 717 on the fifth connecting shaft 720 meshes with and drives the ninth gear 709. The ninth gear 709 drives the first sleeve 717 to rotate through the tenth gear 711 and the eighth gear 708 in sequence. The rotation direction of the eighth gear 708 is opposite to that of the ninth gear 709, driving the fifth connecting shaft 720 to rotate in the reverse direction. By the same principle, the fifth connecting shaft 720 drives the second lead screw 716 to rotate in the reverse direction, achieving the purpose of the slider 707 moving in the reverse direction on the second lead screw 716 and controlling the reverse adjustment angle of the second outer cylinder 501.

[0072] The above is only a preferred embodiment of the present invention and is not intended to limit the protection scope of the present invention.
