The anti-stacking assembly 3 includes a support block 322 slidably connected inside the driving box 14, and one end of the support block 322 is fixedly connected to a push plate 33; The anti-scratch component 4 is arranged inside the processing table 13 to prevent scratches on the bottom of the range hood casing when the anti-piling component 3 pushes the range hood casing; The anti-tilt component 5 is arranged inside the push plate 33, and is used to prevent the range hood housing from tilting when it contacts the transmission component 2, thereby causing the range hood housing to collide with the second conveying frame 12; It should be noted that the conveying assembly 11 includes a driving motor fixedly connected to the back of the first conveying frame 1, the output end of the driving motor is fixedly connected to a transmission roller, the first conveying frame 1 and the second conveying frame 12 are both rotatably connected to moving rollers, and the surfaces of the moving rollers and the transmission rollers inside the first conveying frame 1 are tensioned with a conveyor belt, and the driving motor drives the transmission roller to rotate, so that the transmission roller drives the conveyor belt to rotate, and then the conveyor belt drives the range hood casing to be transported to the top of the processing table 13, and the setting of the transverse roller 132 prevents the range hood casing from being in contact with the top of the processing table 13 when the range hood casing moves from the top of the conveyor belt to the top of the processing table 13. Friction, the first transmission assembly 22 is composed of a third active sprocket fixedly connected to the surface of the driving rod 211 and a third driven sprocket fixedly connected to the surface of the transmission rod 24, and the third active chain and the third driven sprocket are connected through a third chain.

The first gear is meshed with the second gear for transmission, and the fourth active sprocket and the fourth driven sprocket are driven through a fourth chain. When it is necessary to perform secondary transportation on the stacked range hood shells, start the drive motor 21. The drive motor 21 drives the first transmission component 22 and the second transmission component 23 to operate through the drive rod 211, so that the first transmission component 22 and the second transmission component 23 drive the transmission rod 24 to rotate. Furthermore, the transmission rod 24 drives the conveyor belt 242 to rotate through the rotating roller 241. During the rotation of the conveyor belt 242, the stacked range hood shells are driven to move, so that the range hood shells are transported; Specific Embodiment Two, please refer to Figures 1 to 7 , based on the automatic feeding device for range hood shell processing provided in Specific Embodiment One, this embodiment provides a further technical solution: The anti-piling component 3 includes a rotating disk 31 fixedly connected to one end of the drive rod 211 and a moving plate 32 slidably connected inside the drive box 14. One end of the rotating disk 31 is fixedly connected with a transmission rod 311. One end of the transmission rod 311 is fixedly connected with a limiting disk 312. A transmission groove 321 is formed on the surface of the moving plate 32. The transmission rod 311 is arranged inside the transmission groove 321. One end of the moving plate 32 is fixedly connected with one end of the support block 322; When it is necessary to prevent the range hood shells from piling up on the top of the processing table 13, while the drive motor 21 drives the first transmission component 22 and the second transmission component 23 through the drive rod 211, the rotating disk 31 is synchronously driven to rotate. The rotating disk 31 drives the moving plate 32 to reciprocate through the transmission rod 311 and the transmission groove 321. The moving plate 32 drives the push plate 33 to reciprocate through the support block 322. Furthermore, the push plate 33 pushes the range hood shells on the top of the processing table 13 to move to the top of the conveyor belt 242, thereby preventing the range hood shells from piling up on the top of the processing table 13. During the reciprocating movement of the push plate 33, the range hood shells can be sequentially moved onto the conveyor belts 242 on the left and right sides, thereby avoiding mutual collision between the range hood shells during the secondary transportation; Specific Embodiment Three, please refer to Figures 1 to 9 , based on the automatic feeding device for range hood shell processing provided in Specific Embodiment Two, this embodiment provides a further technical solution: The anti-scratch component 4 includes a first driving sprocket 41 fixedly connected to the surface of the driving rod 211 and a rotating rod 42 rotatably connected to the driving box 14 and the inside of the processing table 13, the surface of the rotating rod 42 is fixedly connected to a first driven sprocket 421 and two half gears 422, the first driving sprocket 41 and the first driven sprocket 421 are driven by a first chain 411, the anti-scratch component 4 also includes two groups of telescopic cylinders 43 fixedly connected to the inside of the processing table 13, the tops of the two groups of telescopic cylinders 43 are fixedly connected to a support plate 431, the tops of the support plates 431 are fixedly connected to a plurality of second support frames 432, the insides of the plurality of second support frames 432 are rotatably connected to longitudinal rollers 433, the bottom of the support plate 431 is fixedly connected to a first tooth plate 434, the first tooth plate 434 is meshed with the half gear 422 for transmission; It should be noted that a spring is provided inside the telescopic cylinder 43. When the half gear 422 drives the telescopic cylinder 43 to move through the first tooth plate 434 and the support plate 431, the spring inside the telescopic cylinder 43 is stretched. When the half gear 422 is not in contact with the first tooth plate 434, the spring is restored to its original state due to not being stretched by the support plate 431, so that the support plate 431 drives the second support frame 432 and the longitudinal roller 433 to restore to their initial state. When the support plate 431 drives the second support frame 432 and the longitudinal roller 433 to move out of the processing table 13, the height of the second support frame 432 and the longitudinal roller 433 is higher than the height of the first support frame 131 and the transverse roller 132. When it is necessary to prevent the bottom of the range hood casing from being scratched by the top of the processing table 13, the driving motor 21 drives the first active sprocket 41 to rotate through the driving rod 211, so that the first chain 411 drives the rotating rod 42 to rotate through the first driven sprocket 421, and the rotating rod 42 drives the first tooth plate 434 to rise through the half gear 422. During the rising process, the first tooth plate 434 drives the second support frame 432 and the longitudinal roller 433 to rise through the support plate 431. During the rising process of the longitudinal roller 433, the longitudinal roller 433 drives the range hood casing on the top of the processing table 13 to rise, so that when the pushing plate 33 pushes the range hood casing to move, the bottom of the range hood casing will not rub against the top of the processing table 13, thereby preventing the range hood casing from being scratched; For specific example 4, please refer to Figures 1 to 12 According to the automatic feeding device for range hood shell processing provided in the third specific embodiment, this embodiment provides a further technical solution: The anti-tilt assembly 5 includes two transmission tooth plates 54 fixedly connected to the top of the processing table 13 and a rotating rod 51 rotatably connected to the inside of the pushing plate 33. The surface of the rotating rod 51 is fixedly connected to a transmission gear 511 and a second driving sprocket 512. The transmission gear 511 is meshed with the two transmission tooth plates 54 for transmission. The anti-tilt assembly 5 also includes a bidirectional screw 52 rotatably connected to the inside of the pushing plate 33. The surface of the bidirectional screw 52 is fixedly connected to a second driven sprocket 521. The second driven sprocket 521 and the second driving sprocket 512 are transmitted through a second chain 513. The surface of the bidirectional screw 52 is threadedly connected to two screw blocks 522. The surfaces and backs of the two screw blocks 522 are fixedly connected to a pushing plate 523. It should be noted that when the push plates 523 are close to each other, the position of the tilted range hood housing can be driven to be corrected, and the length of the push plates 523 will not affect the range hood housing from moving to the top of the transverse roller 132, and the height of the transmission gear plate 54 does not exceed the height of the first support frame 131 and the transverse roller 132; When it is necessary to avoid the accumulated range hood casing from tilting when contacting with the conveyor belt 242, during the movement of the push plate 33, the transmission tooth plate 54 drives the rotating rod 51 to rotate through the transmission gear 511, so that the rotating rod 51 drives the second driven sprocket 521 to rotate through the second active sprocket 512 and the second chain 513, thereby causing the bidirectional screw rod 52 to drive the two screw blocks 522 to approach each other. When the two screw blocks 522 approach each other, the two push plates 523 also approach each other. When the push plates 523 approach each other, the position of the range hood casing is rotated, thereby correcting the position of the range hood casing. When the range hood casing contacts with the conveyor belt 242, the range hood casing will not collide with the second conveyor frame 12, thereby preventing the range hood casing from being damaged due to the collision with the second conveyor frame 12. Specific embodiment 5, the present invention also provides an automatic feeding method for range hood shell processing, the automatic feeding method for range hood shell specifically comprises the following steps: Step 1: Place the range hood casings to be processed on the conveying assembly 11 inside the first conveying rack 1 in sequence, and convey the range hood casings to the processing table 13 through the conveying assembly 11; Step 2: driving the anti-stacking component 3 through the transmission component 2, so that the range hood casing on the top of the processing table 13 is pushed to the top of the transmission component 2, and then the transmission component 2 transports the range hood casing in batches; Step 3, the transmission component 2 synchronously drives the anti-scratch component 4, so that when the anti-pile component 3 pushes the range hood housing, its bottom will not be scratched by the processing table 13; Step 4: When the push plate 33 moves, the anti-tilt assembly 5 inside the push plate 33 starts to operate, so that when the range hood casing contacts the transmission assembly 2, the range hood casing will not collide with the second conveying frame 12.

[0025] Working principle: When in use, the range hood casings to be processed are placed on the top of the conveying assembly 11 in sequence, and the range hood casings are conveyed to the top of the processing table 13 in sequence through the conveying assembly 11. When it is necessary to prevent the range hood casings from piling up on the top of the processing table 13, the driving motor 21 drives the first transmission assembly 22 and the second transmission assembly 23 through the driving rod 211, and synchronously drives the rotating disk 31 to rotate, so that the rotating disk 31 drives the moving plate 32 to reciprocate through the transmission rod 311 and the transmission groove 321, and the moving plate 32 drives the pushing plate 33 to reciprocate through the supporting block 322, so that the pushing plate 33 pushes the range hood casings on the top of the processing table 13 to move to the top of the conveyor belt 242, thereby preventing the range hood casings from piling up on the processing table 13, during the reciprocating movement of the pushing plate 33, the range hood casings can be moved to the conveyor belts 242 on the left and right sides in sequence, thereby avoiding the mutual collision of the range hood casings during the secondary conveying process. When the accumulated range hood casings need to be conveyed for the secondary time, the driving motor 21 is started, and the driving motor 21 drives the first transmission assembly 22 and the second transmission assembly 23 to operate through the driving rod 211, so that the first transmission assembly 22 and the second transmission assembly 23 drive the transmission rod 24 to rotate, and then the transmission rod 24 drives the conveyor belt 242 to rotate through the rotating roller 241. The conveyor belt 242 drives the accumulated range hood casings to move during the rotation process, so that the range hood casings are conveyed. It is necessary to prevent the bottom of the range hood casing from colliding with each other. When the top of the processing table 13 is scratched, the driving motor 21 drives the first active sprocket 41 to rotate through the driving rod 211, so that the first chain 411 drives the rotating rod 42 to rotate through the first driven sprocket 421, and the rotating rod 42 drives the first tooth plate 434 to rise through the half gear 422. In the process of rising, the first tooth plate 434 drives the second support frame 432 and the longitudinal roller 433 to rise through the support plate 431. In the process of the longitudinal roller 433 rising, the longitudinal roller 433 drives the range hood shell on the top of the processing table 13 to rise, so that when the pushing plate 33 pushes the range hood shell to move, the bottom of the range hood shell will not rub against the top of the processing table 13, thereby avoiding the range hood shell from being scratched. It is necessary to avoid the accumulation of range hood shells. When the conveyor belt 242 is in contact with the conveyor belt 242 and tilts, during the movement of the push plate 33, the transmission tooth plate 54 drives the rotating rod 51 to rotate through the transmission gear 511, so that the rotating rod 51 drives the second driven sprocket 521 to rotate through the second active sprocket 512 and the second chain 513, and then the bidirectional screw 52 drives the two screw blocks 522 to approach each other. When the two screw blocks 522 approach each other, the two push plates 523 also approach each other. When the push plates 523 approach each other, the position of the range hood housing is rotated, and then the position of the range hood housing is adjusted. When the range hood housing contacts the conveyor belt 242, the range hood housing will not collide with the second conveyor frame 12, thereby preventing the range hood housing from being damaged due to the collision with the second conveyor frame 12.
