[0002] Cardboard box packaging refers to the packaging of products in paper boxes during the distribution process to protect the products, facilitate storage and transportation, and promote sales. Cardboard box packaging has the advantages of easy material sourcing, light weight, easy printing, easy design and molding, and low cost, and is widely used for sales packaging and transport packaging of goods. Cardboard box packaging is one of the most widely used packaging methods.

[0003] Currently, existing cardboard boxes need to be sealed with tape after production to facilitate the subsequent filling of items. However, since scraps of paper and dust inevitably remain at the sealing area during the production process, directly sealing with tape will inevitably affect the strength of the tape seal, thus presenting certain shortcomings. Therefore, we propose a sealing device for cardboard box production. Utility Model Content

Detailed Implementation

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0017] Please see Figures 1 to 7 This utility model provides a technical solution: a sealing device for carton production, including a conveyor table 1 and a mounting top plate 2. The mounting top plate 2 is disposed above the conveyor table 1. A dust removal mechanism for cleaning the sealing area of ​​the carton is provided on one side below the conveyor table 1 and at the bottom of the mounting top plate 2. By setting the dust removal mechanism, dust can be removed from the sealing area of ​​the carton, thereby improving the firmness of the sealing with tape and preventing the tape's adhesiveness from being affected by paper scraps, dust, etc.

[0018] The dust removal mechanism includes a mounting plate 3, an electric roller 4, a cleaning sleeve 5, a dust suction hood 6, a negative pressure box 7, and a negative pressure pump 11. The mounting plate 3 is fixedly installed at the bottom of the mounting top plate 2. The electric roller 4 is located inside the mounting plate 3. The cleaning sleeve 5 is fitted onto the outside of the electric roller 4. The dust suction hood 6 is fixedly installed on one side of the mounting plate 3. The negative pressure box 7 is located below the conveyor table 1. A suction pipe 8 is installed at the input end of the negative pressure box 7, and one end of the suction pipe 8 is fixedly connected to the input end of the dust suction hood 6. A collection box 9 is installed inside the negative pressure box 7. A filter screen 10 is installed inside the negative pressure box 7 and located on one side of the collection box 9. The negative pressure pump 11 is located on one side of the negative pressure box 7, and the input end of the negative pressure pump 11 extends to the negative pressure box 7. The filter screen 10 inside the box 7 is located on one side. When the electric roller 4 rotates, it drives the cleaning brush 5 to rotate, which can brush off the paper scraps and dust on the outside of the carton seal. At the same time, the negative pressure pump 11 discharges the air in the negative pressure box 7 to create a negative pressure, and the suction pipe 8 generates suction, which can suck the brushed paper scraps and dust into the negative pressure box 7 through the dust hood 6 and collect them through the collection box 9. This can prevent the brushed paper scraps and dust from flying and affecting the hygiene of the device. The electric roller 4 rotates counterclockwise, which can brush the paper scraps and dust to the bottom of the dust hood 6. The collection box 9 is a pull-out device inside the negative pressure box 7. The collection box 9 can be pulled out from the negative pressure box 7 to clean the collected paper scraps.

[0019] The bottom of the mounting plate 2 is equipped with a pressing and cutting mechanism for pressing and cutting tape. By setting the pressing and cutting mechanism, the tape can be pressed firmly at the carton sealing position. After the carton is sealed with tape, the tape can be cut to complete the pressing and cutting.

[0020] The cutting mechanism includes a rotating frame 13, a torsion spring roller frame 14, a pressure roller 15, and a cutting blade 16. The rotating frame 13 is fixedly installed at the bottom of the mounting top plate 2. The torsion spring roller frame 14 is rotatably installed on the outside of the rotating frame 13. Torsion springs are provided on both sides of the torsion spring roller frame 14, and one end of the torsion spring is fixedly connected to the rotating frame 13. The pressure roller 15 is located on the inside of the torsion spring roller frame 14, and the cutting blade 16 is located on one side of the torsion spring roller frame 14. The pressure roller 15 can press the tape tightly onto the carton seal. At the opening, the torsion spring roller frame 14 and pressure roller 15 can rotate outside the rotating frame 13 during the movement of the carton, squeezing the torsion spring. The elasticity of the torsion spring can ensure that the pressure roller 15 presses the tape tightly at the carton opening. After the tape is sealed at the carton opening, it moves to the side of the pressure roller 15 and the torsion spring rebounds, which can drive the torsion spring roller frame 14 to reset. When the torsion spring roller frame 14 resets, the cutting blade 16 can cut the tape at the same time as resetting, thus completing the pressing and cutting of the tape.

[0021] A tape mounting bracket 12 is provided at the bottom of the mounting plate 2 and on one side of the cutting mechanism. Tape for sealing the carton is provided on the outside of the tape mounting bracket 12. The tape is rotatably mounted on the outside of the tape mounting bracket 12. The tape mounting bracket 12 can limit the tape. After the tape is mounted on the tape mounting bracket 12, the tape needs to be pulled out to one side of the pressure roller 15 to ensure that it can be attached to the outside of the carton during the movement of the carton.

[0022] The inner side of the conveyor table 1 is provided with several electric conveyor rollers 17 for conveying cartons; the electric conveyor rollers 17 are existing mechanisms, which can convey cartons placed on their upper surface by rotating on their own.

[0023] An adjustment box 18 is provided at the bottom of the conveyor table 1. A bidirectional lead screw 19 is rotatably installed inside the adjustment box 18. Two sleeve blocks 20 are threaded on the outer side of the bidirectional lead screw 19. A connecting frame 21 is fixedly installed on one side of each sleeve block 20. A guide plate 22 is fixedly installed on one side of the connecting frame 21. One end of the bidirectional lead screw 19 extends to the outer side of the adjustment box 18 and is fixedly installed with an adjustment turntable 24. By rotating the adjustment turntable 24, the bidirectional lead screw 19 is rotated, which in turn drives the two sleeve blocks 20 to move to both sides through the threads on its outer side. Then, the connecting frame 21 and the guide plate 22 can be moved to both sides through the sleeve blocks 20, thereby meeting the guiding and conveying needs of cartons of different sizes.

[0024] Lifting mounting frames 23 are provided on both sides of the conveyor table 1, and the mounting top plate 2 cooperates with the lifting mounting frames 23. The lifting mounting frames 23 are equipped with guide rails, and the mounting top plate 2 is equipped with self-locking linear motors that cooperate with the guide rails on both sides. The self-locking linear motors can drive the mounting top plate 2 to adjust the height, thereby meeting the sealing of cartons of different heights.

[0025] In summary, this sealing device for carton production, when in use, first adjusts the width of the guide plate 22 and the height of the mounting top plate 2 according to the size of the carton to be sealed. Rotating the adjusting turntable 24 drives the bidirectional lead screw 19 to rotate, which in turn drives the two sleeve blocks 20 to move to both sides via the threads on its outer side. Then, the sleeve blocks 20 drive the connecting frame 21 and the guide plate 22 to move to both sides, thus accommodating the guiding and conveying of cartons of different sizes. The height of the mounting top plate 2 can be adjusted by moving the self-locking linear motors on both sides of the mounting top plate 2 outside the guide rail. After adjustment, the carton to be sealed is placed on the electric conveyor roller 17, which conveys the carton. When the carton is conveyed to below the cleaning sleeve 5, the rotation of the electric roller 4 drives the cleaning sleeve 5 to rotate, brushing off the paper scraps and dust on the outside of the carton's sealing area. The air in the negative pressure box 7 is discharged by the negative pressure pump 11, creating a negative pressure. The suction pipe 8 then generates suction, which sucks the brushed paper scraps and dust into the negative pressure box 7 through the suction hood 6. The dust is then collected in the collection box 9, thus preventing the brushed paper scraps and dust from flying around and affecting the hygiene of the device. After cleaning, the carton moves to the side of the cleaning sleeve 5, and the tape is stuck to one side of the carton. Then it comes into contact with the pressure roller 15. During the movement of the carton, the torsion spring roller frame 14 and the pressure roller 15 can rotate outside the rotating frame 13, squeezing the torsion spring. The elasticity of the torsion spring ensures that the pressure roller 15 presses the tape tightly at the carton seal. After the tape seals the carton, it moves to the side of the pressure roller 15, and the torsion spring rebounds, which drives the torsion spring roller frame 14 to reset. When the torsion spring roller frame 14 resets, the cutting blade 16 cuts the tape at the same time, thus completing the pressing and cutting of the tape.

[0026] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
