[0002] Cartons are the most widely used packaging products. According to different materials, there are corrugated cartons, single-layer cardboard boxes, etc., with various specifications and models. Commonly used cartons have three layers, five layers, and seven layers are less used. Each layer is divided into inner paper, corrugated paper, core paper, and face paper. The inner and face papers are made of tea board paper and kraft paper, and the core paper is made of corrugated paper. The colors and feels of various papers are different, and the papers produced by different manufacturers also have different colors and feels; Packaging cartons need to go through multiple processes during production, and "flattening" is an important step. The flattening device is mainly used to ensure that the carton board is flat and reduce warping, thereby improving the quality of subsequent processes such as folding and bonding.

[0003] There are roller flattening machines, pneumatic / hydraulic flattening machines, vibrating flattening machines, etc. Among them, roller flattening machines are used more frequently. The packaging carton is conveyed under the flattening roller through a conveyor belt, and the packaging carton on the conveyor belt is pressed flat by the flattening roller, thus completing the flattening operation of the packaging carton.

[0004] However, since there may be some particles on the packaging carton, during the flattening operation, some particles will adhere to the flattening roller. When the flattening roller performs the flattening operation on the next packaging carton, the adhered particles will press out pits on the originally flat packaging carton, and even cause damage to the outer surface of the packaging carton, affecting the quality of the packaging carton.

Specific implementation manner

[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0024] Please refer to Figure 1 – Figure 6 , a flattening device for processing packaging cartons, including a base 1 and a conveyor belt 2 installed on the base 1. Two support plates 3 are connected to one side of the base 1 close to the conveyor belt 2. The two support plates 3 are respectively located on both sides of the conveyor belt 2. A pressing roller 4 is connected above the conveyor belt 2 between the two support plates 3. A lifting assembly is connected to the side of the pressing roller 4 away from the conveyor belt 2. The lifting assembly is connected to the two support plates 3. A scraping plate 5 is connected to the side of the pressing roller 4 close to the front end of the conveyor belt 2. The scraping plate 5 abuts against the pressing roller 4. An installation assembly is connected to the side of the scraping plate 5 away from the pressing roller 4.

[0025] As shown in Figure 1 – Figure 6As shown in the figure, a flattening device for processing packaging cartons in the present utility model is similar in structure to the existing flattening device for processing packaging cartons. The main improvement of the present utility model is that the particulate impurities attached to the pressure roller 4 can be scraped off by the scraping plate 5, avoiding surface extrusion damage to the packaging carton and improving the quality of packaging carton processing. For example, Figures 1 to 6 As shown in the figure, when the flattening device for processing packaging cartons in the present utility model is in use, when the conveyor belt 2 transports the cardboard of the packaging carton between the two support plates 3, the pressure roller 4 is moved downward by the lifting assembly and abuts against the cardboard. As the conveyor belt 2 continues to move, the cardboard drives the pressure roller 4 to roll, thereby gradually flattening the cardboard of the entire packaging carton. At the same time, as the pressure roller 4 rotates, the particulate matter attached to the pressure roller 4 can be scraped off by the scraping plate 5 that abuts against it, thereby preventing these particles from being pressed onto the cardboard as the pressure roller 4 rolls, causing damage and pits to the cardboard and affecting the price efficiency of the packaging carton.

[0026] For example, Figure 1 - Figure 5 As shown in the figure, the lifting assembly includes a cross plate 6 and a lifting cylinder 7. The two ends of the cross plate 6 are respectively fixedly connected to one end of the two support plates 3 away from the base 1. The lifting cylinder 7 is fixedly connected to the side of the cross plate 6 away from the base 1. The telescopic rod of the lifting cylinder 7 penetrates through the cross plate 6 and is fixedly connected to a lifting plate 8. Both ends of the lifting plate 8 are fixedly connected with shaft blocks 9. Both ends of the pressure roller 4 are respectively rotatably connected to the two shaft blocks 9 through rotating shafts. Through the lifting cylinder 7 on the cross plate 6, the lifting plate 8 is driven to move up and down between the two support plates 3. The pressure roller 4 rolls below the lifting plate 8 through the shaft blocks 9 at both ends of the lifting plate 8, thereby flattening the cardboard of the packaging carton on the conveyor belt 2.

[0027] For example, Figure 1 - Figure 5 As shown in the figure, the installation assembly includes an L-shaped mounting plate 10 and a connecting plate 11. One end of the L-shaped mounting plate 10 is fixedly connected to the cross plate 6. The connecting plate 11 is fixedly connected to the side of the scraping plate 5 away from the pressure roller 4. The end of the L-shaped mounting plate 10 away from the cross plate 6 is connected to the connecting plate 11. When the scraping plate 5 is installed on the side of the pressure roller 4 through the installation assembly, through the connection and fixation of the connecting plate 11 and the L-shaped mounting plate 10, the edge of the scraping plate 5 can be abutted against the side of the pressure roller 4. As the pressure roller 4 rotates, the impurities and particles attached to the surface of the pressure roller 4 are scraped off clean, keeping the surface of the pressure roller 4 smooth and free of impurities.

[0028] For example, Figure 1 - Figure 6As shown, a plurality of threaded holes 101 are formed through the side of the L-shaped mounting plate 10 close to the connecting plate 11. A plurality of mounting holes 102 are formed through the side of the connecting plate 11 close to the L-shaped mounting plate 10, and a plurality of bolts 12 are connected to the side of the connecting plate 11 away from the L-shaped mounting plate 10. The threaded rods of the plurality of bolts 12 respectively pass through the plurality of mounting holes 102 and are respectively threadedly connected with the plurality of threaded holes 101. The bolts 12 pass through the mounting holes 102 and are threadedly fixed with the threaded holes 101, so that the connecting plate 11 and the scraping plate 5 can be easily disassembled and installed on the L-shaped mounting plate 10. When there are a large number of scraping particles and impurities on the scraping plate 5 and the connecting plate 11, the connecting plate 11 and the scraping plate 5 can be regularly disassembled and the scraped objects can be cleaned.

[0029] like Figure 2 - Figure 6 As shown, both ends of the scraper plate 5 are fixedly connected with baffles 13, and the two baffles 13 are respectively slidably connected to the two ends of the pressure roller 4. The scraped material can be blocked on the scraper plate 5 and the connecting plate 11 by the two baffles 13 to prevent the scraped impurities from falling onto the conveyor belt 2 from both ends.

[0030] like Figure 1 - Figure 3 As shown, the adjacent sides of the two support plates 3 are provided with limit slots 301, and the two shaft blocks 9 are respectively slidably connected with the two limit slots 301. The two shaft blocks 9 slide up and down in the limit slots 301 of the two support plates 3, so that the lifting process of the lifting plate 8 is more stable and not easy to deviate.

[0031] like Figure 1 - Figure 5 As shown, an axis slot 302 is provided on one side of one of the limiting slots 301 away from the axis block 9, and a track frame 14 is fixedly connected to the side of the axis slot 302 away from the limiting slot 301. A driving motor 15 is slidably connected inside the track frame 14, and an output shaft of the driving motor 15 passes through the axis slot 302 and the adjacent axis block 9, and is fixedly connected to the rotating shaft of the pressure roller 4, and the output shaft of the driving motor 15 is slidably connected to the axis slot 302. When the lifting cylinder 7 drives the lifting plate 8 and the pressure roller 4 to move downward, and makes the pressure roller 4 rest on the cardboard of the packaging carton on the conveyor belt 2, the rotating shaft at the end of the pressure roller 4 drives the drive motor 15 to move downward in the track frame 14 through the output shaft of the drive motor 15. During the subsequent flattening operation, the drive motor 15 can be controlled and started to drive the pressure roller 4 to rotate actively, and the rotation and movement of the pressure roller 4 are synchronized with the movement of the conveyor belt 2, so as to avoid the cardboard of the packaging carton from slipping and wearing on the conveyor belt 2 during the flattening operation. The outer shell of the drive motor 15 is rectangular and can slide up and down in the track frame 14. When driving the pressure roller 4 to rotate, the drive motor 15 will not rotate on its own in the track frame 14.

[0032] likeFigure 2 and Figure 3 As shown in Figure 3 , a bottom roller 16 is connected between two support plates 3. Both ends of the bottom roller 16 are rotatably connected to the two support plates 3 through rotating shafts respectively. The bottom roller 16 is located between the upper and lower belts of the conveyor belt 2 and is directly below the pressing roller 4. When the pressing roller 4 flattens the cardboard on the conveyor belt 2, cooperating with the bottom roller 16 below can prevent the conveyor belt 2 and the cardboard from sagging downward, making the flattening operation of the packaging carton more stable.

[0033] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention.
