[0024] As Figures 1 to 7 shown, it shows a dust removal device for corrugated paper production in an embodiment of the present disclosure, including a frame 1, and further including: a conveyor belt 2, a dust suction box 3, a brush 4, and a cutting knife 5. A support plate 25 is fixedly connected to the top of the frame 1. The conveyor belt 2 is arranged in the frame 1 through a transmission mechanism. A number of through holes are provided on the conveyor belt 2. The dust suction box 3 is arranged in the frame 1 through a dust suction mechanism. The top of the dust suction box 3 is in contact with the inner wall of the conveyor belt 2, and can perform double-sided dust removal on the corrugated paperboard. The brush 4 is arranged at the top of the frame 1 through a rotating mechanism, and is used to drive the brush 4 to brush off the dust on the surface of the corrugated paperboard. The cutting knife 5 is arranged at the top of the frame 1 through a cutting mechanism, and is used to cut the corrugated paperboard after production. Through the cooperation between the transmission mechanism and the dust suction mechanism, the corrugated paperboard after production can be stably adsorbed on the conveyor belt 2 and stably conveyed. Through the cooperation between the dust suction mechanism and the rotating mechanism, the dust on the surface of the corrugated paperboard can be comprehensively cleaned. Through the setting of the cutting mechanism, it is convenient to cut the corrugated paperboard after production. Through the cooperation between the conveyor belt 2, the dust suction box 3, the brush 4, the cutting knife 5, the transmission mechanism, the dust suction mechanism, and the rotating mechanism, the corrugated paperboard after production can be comprehensively cleaned, reducing the residue of dust on the surface of the corrugated paperboard and improving the dust removal efficiency of the corrugated paperboard.

[0025] As Figures 1 to 4As shown in the figure, the dust suction mechanism includes: a diversion box 6, an air outlet box 7, a fan 8, and an upper dust removal component. The diversion box 6 is connected to the bottom end of the dust suction box 3. The air outlet box 7 is connected to the bottom end of the diversion box 6. The fan 8 is installed inside the air outlet box 7, and the output end of the fan 8 faces the bottom end of the air outlet box 7. The upper dust removal component is arranged at the top end of the frame 1 and can remove dust from the upper surface of the corrugated cardboard. The upper dust removal component includes: a dust removal box 9, a dust suction pipe rack 10, and a conveying pipe 11. There are two dust removal boxes 9, and the two dust removal boxes 9 are fixedly connected to the top end of the frame 1 through a top frame 26. The dust suction pipe rack 10 is connected to the two dust removal boxes 9. One end of the conveying pipe 11 is connected to the dust suction pipe rack 10, and the other end of the conveying pipe 11 is connected to the air outlet box 7. The fan 8 installed on the air outlet box 7 blows air out of the air outlet box 7, creating a negative pressure in the diversion box 6 and the dust suction box 3. Thus, through a number of through holes opened on the conveyor belt 2, the corrugated cardboard during transportation is firmly adsorbed on the conveyor belt 2. And during this process, the dust on the bottom surface of the corrugated cardboard can also be adsorbed and cleaned up.

[0026] As Figure 1 , Figure 3 and Figure 5 shown in the figure, the rotating mechanism includes: a fixed plate 12 and a first motor 13. There are two fixed plates 12, and the two fixed plates 12 are both fixedly connected to the top end of the frame 1 through a mounting frame 27. The brush 4 is rotatably connected between the two fixed plates 12. The first motor 13 is installed on one of the fixed plates 12, and the output end of the first motor 13 passes through the fixed plate 12 and is fixedly connected to one end of the brush 4. The first motor 13 drives the brush 4 rotatably connected between the two fixed plates 12 to rotate, thus sweeping off the dust on the surface of the corrugated cardboard.

[0027] As Figures 1 to 3 shown in the figure, the transmission mechanism includes: a conveying shaft 14 and a second motor 15. There are two conveying shafts 14, and the two conveying shafts 14 are both rotatably connected inside the frame 1. The conveyor belt 2 is drivingly connected between the two conveying shafts 14. The second motor 15 is installed on one side of the frame 1, and the output end of the second motor 15 passes through the frame 1 and is fixedly connected to one of the conveying shafts 14. The second motor 15 drives the conveying shaft 14 to rotate. When the conveying shaft 14 rotates, since the conveyor belt 2 is drivingly connected between the two conveying shafts 14, the conveyor belt 2 is driven to convey the corrugated cardboard.

[0028] As Figure 1 , Figure 2 , Figure 3 and Figure 6As shown in the figure, the cutting mechanism includes: a support frame 16, a sliding rod 17, a sliding carriage 18, a support spring 19, and a driving assembly. A sliding hole is provided on the support frame 16, and the sliding carriage 18 is slidably connected within the sliding hole. The support frame 16 is fixedly connected to the top end of the machine frame 1. The sliding rod 17 is slidably arranged within the support frame 16 through a sliding assembly. The cutting knife 5 is fixedly connected to the bottom end of the sliding rod 17. The sliding carriage 18 is slidably connected to the support frame 16, and the bottom end of the sliding carriage 18 is fixedly connected to the sliding rod 17. There are two support springs 19, and both support springs 19 are sleeved on the sliding carriage 18. The two ends of the two support springs 19 are respectively fixedly connected to the sliding carriage 18 and the support frame 16. The driving assembly is arranged at the top end of the support frame 16 and is used to drive the sliding carriage 18 and the sliding rod 17 to move up and down. The driving assembly includes: a top plate 20, an eccentric wheel 21, and a third motor 22. The top plate 20 is fixedly connected to the top end of the support frame 16. The eccentric wheel 21 is rotatably connected to one side of the top plate 20. The circumferential surface of the eccentric wheel 21 contacts the top end of the sliding carriage 18. The third motor 22 is installed on the other side of the top plate 20. The output end of the third motor 22 penetrates through the top plate 20 and is fixedly connected to the eccentric wheel 21. The sliding assembly includes: a sliding box 23 and a sliding block 24. There are two sliding boxes 23, and both sliding boxes 23 are fixedly connected within the support frame 16. The sliding blocks 24 are fixedly connected to both ends of the sliding rod 17. The two sliding blocks 24 are respectively slidably connected within the two sliding boxes 23. By installing the third motor 22 on the top plate 20 to drive the eccentric wheel 21 to rotate, when the eccentric wheel 21 rotates, it strikes the sliding carriage 18 downward, so that the sliding carriage 18 drives the sliding rod 17 to descend. When the sliding rod 17 descends, it drives the cutting knife 5 to cut the corrugated cardboard. When the eccentric position of the eccentric wheel 21 rotates to the upper side, the sliding carriage 18 returns to its original position through the support of the support spring 19, thus realizing continuous cutting of the corrugated cardboard by the cutting knife 5.

[0029] Working principle: When dust removal is required after the production of corrugated cardboard, the corrugated cardboard is placed on the conveyor belt 2. The fan 8 installed on the air outlet box 7 blows air out of the air outlet box 7, creating a negative pressure in the diversion box 6 and the dust suction box 3. As a result, through a number of through holes opened on the conveyor belt 2, the corrugated cardboard during transportation is firmly adsorbed on the conveyor belt 2. And during this process, the dust on the bottom surface of the corrugated cardboard can also be adsorbed and cleaned. At this time, the second motor 15 drives the conveyor shaft 14 to rotate. When the conveyor shaft 14 rotates, since the conveyor belt 2 is driven between the two conveyor shafts 14, the conveyor belt 2 is driven to transport the corrugated cardboard. When the corrugated cardboard is transported under the brush 4, the first motor 13 drives the brush 4 rotatably connected between the two fixing plates 12 to rotate, thus sweeping off the dust on the surface of the corrugated cardboard. After that, the fan 8 blows air outside the air outlet box 7, creating suction in the conveying pipe 11 and the dust suction pipe rack 10 connected to the air outlet box 7, so that the dust removal box 9 absorbs the dust swept up on the corrugated cardboard, thereby comprehensively cleaning the dust on the corrugated cardboard. When the corrugated cardboard is transported under the cutting knife 5, the third motor 22 installed on the top plate 20 drives the eccentric wheel 21 to rotate. When the eccentric wheel 21 rotates, it strikes the carriage 18 downward, causing the carriage 18 to drive the slide rod 17 to descend. When the slide rod 17 descends, it drives the cutting knife 5 to cut the corrugated cardboard. When the eccentric position of the eccentric wheel 21 rotates to the upper side, the carriage 18 returns to its original position through the support of the support spring 19, thus enabling the cutting knife 5 to continuously cut the corrugated cardboard.

Although the present disclosure has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present disclosure can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present disclosure, and they should all be covered within the scope of the claims of the present disclosure.
