Description

Technical Field

[0001] This utility model relates to the field of single-facer technology, and more specifically, to a single-facer for corrugated cardboard production. Background Technology

[0002] The single-facer is one of the heart components of a corrugated carton production line. It is the machine that forms the corrugations, and its main part is the corrugating roller. The quality of the corrugating roller, the paper feeding method, and the overall precision of the single-facer will determine the quality of each flat sheet and each corrugated sheet produced by the single-facer.

[0003] A single-facer is a machine used to produce corrugated core paper (a specific term for wavy paper in cardboard). In the corrugated packaging industry, it is known as the "heart of the corrugated cardboard production line." A single-facer consists of a roll support and a single-face corrugating machine. First, the corrugated core paper is heated, then it is formed into the desired flute shape by corrugating rollers. Finally, glue is applied to the flute peaks and bonded to the single-face corrugated paper to form single-face corrugated cardboard.

[0004] Corrugated rolls include upper and lower corrugated rolls. These rolls operate in combination with glue rollers and pressure rollers on the frame of a single-facer, bonding the corrugated core paper and the corrugated face paper to form corrugated board. However, existing single-facers do not pre-clean the side of the corrugated paper and face paper that will adhere to each other before glue application. This results in dust adhering to the surface affecting the subsequent glue application to the bottom of the corrugated paper and the bonding effect between the two, thus impacting the processing quality of the corrugated board.

[0005] Therefore, a solution needs to be proposed to address this problem. Utility Model Content

It is then pressed by the upper pressure roller 7 to achieve adhesion with the corrugated paper. After adhesion, the paper is discharged from the paper outlet 4. This application is an improvement on the cleaning structure inside the housing 1. The more detailed internal structure of the single-facer, the processing distance, and the rotation drive method between each roller are mature existing technologies and do not involve the technical content to be improved in this application. Therefore, they will not be described in detail here. You can directly refer to the description of the single-facer at the website "https: / / baike.baidu.com / item / %E5%8D%95%E9%9D%A2%E6%9C%BA / 8012847".

[0024] Cleaning roller 12 and cleaning roller 23 are rotatably connected to the inner wall of the housing 1. Cleaning roller 12 and cleaning roller 23 are at the same height. Cleaning roller 12 contacts the side of the corrugated paper used for bonding, and cleaning roller 23 contacts the side of the face paper used for bonding. Brushes 25 are fixedly connected to the surfaces of cleaning roller 12 and cleaning roller 23. Brushes 25 contact the side of the corrugated paper and face paper used for bonding.

[0025] The outer wall of the housing 1 is equipped with a drive device for driving the first cleaning roller 12 and the second cleaning roller 13 to rotate.

[0026] The drive unit includes a mounting bracket 15 fixedly connected to the outer wall of the housing 1. One end of each of the cleaning roller 12 and the second cleaning roller 13 extends to the outer wall of the housing 1 and is fixedly connected to a driven gear 16. The inner wall of the housing 1 has through holes for the ends of the cleaning roller 12 and the second cleaning roller 13 to extend out. A rotating rod 17 is rotatably connected to the inner wall of the mounting bracket 15. A motor 18 for driving the rotating rod 17 to rotate is fixedly installed on the side wall of the mounting bracket 15. The motor 18 is a servo motor. One end of the rotating rod 17 is connected to the output shaft of the motor 18. Two symmetrically distributed drive gears 19 are fixedly connected to the outer wall of the rotating rod 17. The drive gears 19 on both sides mesh with the driven gears 16 on both sides respectively. Both the drive gears 19 and the transmission gears are bevel gears.

[0027] A collection box 14 is provided below both cleaning roller 12 and cleaning roller 2 13, and the collection boxes 14 on both sides are detachably connected to the box body 1.

[0028] The inner wall of the box 1 has two sets of slots for inserting the collection box 14. Two support plates 20 for placing the collection boxes 14 on both sides are fixedly connected to the inner wall of the box 1. The height of the slot is above the support plate 20. A fixing plate 21 is fixedly connected to the side wall of the collection box 14. A handle 26 is fixedly connected to the side of the fixing plate 21 away from the collection box 14. Extension plates 27 are fixedly connected to both sides of the fixing plate 21. Fastening holes 1 are opened on both sides of the extension plates 27. Two symmetrically distributed ear plates 22 are fixedly connected to the outer wall of the box 1. Fastening holes 22 are opened on both sides of the ear plates 22, corresponding to the position of fastening holes 1. Fastening bolts 23 pass through the fastening holes 1 and fastening holes 2.

[0029] Two symmetrically distributed baffles 24 are fixedly connected to the inner wall of the housing 1. Both baffles 24 are arc-shaped, and the curvature of the baffles 24 is consistent with the curvature of the cleaning roller 12 and the cleaning roller 23. The baffles 24 respectively block the cleaning roller 12 and the cleaning roller 23 on the side closest to each other. The baffles 24 can effectively reduce the occurrence of dust during the rotation cleaning process of the cleaning roller 12 and the cleaning roller 23.

[0030] Working principle: Corrugated paper is pulled by preheating roller 10 and guide roller 9, passing between the upper and lower corrugated paper to create indentations. After being glued by the gluing roller, it enters the laminating tank. The face paper is guided by preheating roller 21 and lower pressure roller 8, and after preheating, it enters the laminating tank to bond with the corrugated paper. During this process, the corrugated paper is in a vertical transport section between preheating roller 10 and guide roller 9, and the face paper is also in a vertical transport section between preheating roller 21 and lower pressure roller 8. Cleaning rollers 12 and 13 are positioned between the vertical sections of the corrugated paper and face paper. During transport, motor 18 drives rotating rod 17 to rotate, which in turn drives the two drive gears 19 on either side. The drive gears 19 on both sides rotate symmetrically, which drives the driven gears 16 meshing with them to rotate. The rotation directions of the two gears are opposite, and the driven gears 16 on both sides drive the cleaning roller 12 and the cleaning roller 13 to rotate. The cleaning roller 12 on the left side rotates counterclockwise under the drive of the driven gear 16, brushing off the dust and impurities on the corrugated paper bonding surface and collecting them in the collection box 14 corresponding to its position. The cleaning roller 13 on the right side rotates clockwise under the drive of the driven gear 16, brushing off the dust and impurities on the face paper bonding surface and collecting them in the collection box 14 corresponding to its position. This achieves the cleaning of the bonding surfaces of the corrugated paper and face paper, reduces the dust and impurities on the bonding surfaces, and improves the production quality of corrugated cardboard.

[0031] After the collection box 14 has collected dust and impurities for a period of time, remove the nut on the fastening bolt 23 and take the bolt out from the fastening hole one and fastening hole two. The extension pieces 27 on both sides can then be separated from the ear pieces 22 on both sides. At this time, by holding the handle 26 and pulling, the collection box 14 can be pulled out from the box 1. The dust and impurities collected in the collection box 14 can be poured out and cleaned. After cleaning, the collection box 14 is reinserted into the box 1 through the slot, so that the collection box 14 is placed on the support piece 20. Then, the extension pieces 27 and ear pieces 22 are reattached, and the fastening bolts 23 are inserted into the fastening holes one and fastening holes two for fixation, making the cleaning of dust and impurities more convenient.
