Description

Technical Field

[0001] The utility model relates to the technical field of corrugated paper processing, and more specifically, to a frame for producing corrugated paper. Background Art

[0002] Corrugated cardboard is a board material consisting of a corrugated core layer and a covering layer formed between two or more layers of cardboard, commonly known as "corrugated sheet", "corrugated paper", "corrugated core paper", "corrugated paper core", and "corrugated base paper".

[0003] At present, the common two-layer corrugated paper process usually consists of core paper and face paper. The corrugated waves are formed by rolling with corrugating rollers, and the face paper and core paper are glued together using a gluing wheel to form corrugated paper. During the entire processing process, the corrugated paper needs to be humidified and preheated to ensure the forming effect of the corrugated paper. However, most of the existing corrugated paper production racks use different racks for preheating, corrugating and laminating processes during the production of corrugated paper. Each rack will occupy a certain amount of space, and the multiple racks are relatively scattered, resulting in poor forming effect. Utility Model Content

[0014] 3. Beneficial effects

[0015] Compared with the prior art, the advantages of the present invention are:

[0016] (1) In this solution, the middle corrugating roller and the pressure roller cooperate to corrugate the core paper into shape. The formed core paper is glued by the gluing wheel device. The face paper preheating wheel preheats the face paper. The preheated face paper and the formed core paper are pressed together by the middle corrugating roller and the pressure roller. Finally, they are output to the slitting equipment for secondary heating through the output preheating wheel. The frame has a centralized structure design, which integrates the preheating, corrugating and laminating functions into one, reducing the space occupied and improving the production efficiency of corrugated paper. The face paper will be preheated in advance before laminating. The preheated face paper can further improve the flatness of the corrugated paper and the overall forming effect. Before the two layers of corrugated paperboard are conveyed to the slitting equipment, the two layers of corrugated paperboard are heated and shaped for a second time by the device, which can maintain a good moisture balance of the two layers of paperboard, improve the strength of the paperboard and make it less prone to deformation.

A guide wheel assembly 8 is provided on both the face paper preheating wheel 6 and the output preheating wheel 7.

[0027] In this embodiment, the core paper enters the mounting frame 1 and first passes between the upper corrugating roller 2 and the middle corrugating roller 3. The upper corrugating roller 2 and the middle corrugating roller 3 cooperate to corrugate the core paper. The formed core paper passes through the pasting wheel device 5 for gluing, and then passes between the middle corrugating roller 3 and the pressure roller 4. At the same time, a guide wheel assembly 8 guides the face paper to the surface of the face paper preheating wheel 6. The face paper is preheated by the face paper preheating wheel 6 and conveyed between the middle corrugating roller 3 and the pressure roller 4. The middle corrugating roller 3 and the pressure roller 4 cooperate to bond the face paper and the corrugated core paper under the action of glue, thereby forming corrugated paper. The formed corrugated paper is guided by another guide wheel assembly 8 and output on the surface of the output preheating wheel 7.

[0029] In this embodiment, the core paper passes through the upper side of the water spray box 9 before passing through the upper corrugated roller 2 and the middle corrugated roller 3. The water spray box 9 cooperates with the spray device to spray water on the cardboard to correct the warping of the cardboard. At the same time, it helps the glue to penetrate quickly to ensure the bonding effect.

[0030] Specifically, a paper guide 10 is fixedly connected to the mounting frame 1 , and the paper guide 10 is located on one side of the water spray box 9 corresponding to the upper corrugated roller 2 and the middle corrugated roller 3 .

[0031] In this embodiment, the paper guide 10 is arranged after the water spray box 9 wets the core paper, and guides the core paper between the upper corrugating roller 2 and the middle corrugating roller 3 for corrugation forming.

[0032] Specifically, an arc-shaped plate 11 is fixedly connected inside the mounting frame 1 , and the arc-shaped plate 11 matches the circumferential surface of the tissue paper preheating wheel 6 .

[0033] In this embodiment, the arc-shaped plate 11 restricts the facial paper so that the facial paper can contact and fit with the facial paper preheating wheel 6, so that the facial paper preheating wheel 6 can preheat the facial paper.

[0034] Specifically, a paper partition board 12 is fixedly connected to the mounting frame 1 , and the paper partition board 12 corresponds to the middle corrugated roller 3 and the pressure roller 4 .

[0035] In this embodiment, the upper and lower surfaces of the separator paper 12 correspond to the face paper and the core paper respectively, so that the face paper and the core paper can accurately pass through between the middle corrugated roller 3 and the pressure roller 4 for lamination.

[0036] Specifically, a scraping plate 13 is provided in the mounting frame 1 , and the scraping plate 13 contacts the circumferential surface of the pressure roller 4 .

[0037] In this embodiment, when the pressure roller 4 cooperates with the middle corrugated roller 3 to operate, the scraper 13 cleans the surface of the pressure roller 4 to ensure the lamination effect of the face paper and the core paper.

[0038] Working principle: The core paper passes between the upper corrugating roller 2 and the middle corrugating roller 3 and enters the mounting frame 1. The upper corrugating roller 2 and the middle corrugating roller 3 cooperate to corrugate the core paper. The formed core paper passes through the pasting wheel device 5 for gluing, and then passes between the middle corrugating roller 3 and the pressure roller 4. At the same time, a guide wheel assembly 8 guides the face paper to the circumferential surface of the face paper preheating wheel 6. The face paper is preheated and conveyed through the face paper preheating wheel 6, and then passes between the middle corrugating roller 3 and the pressure roller 4. The middle corrugating roller 3 and the pressure roller 4 cooperate to bond the face paper and the corrugated core paper under the action of glue to form corrugated paper. The formed corrugated paper is guided by another guide wheel assembly 8 and contacts the circumferential surface of the output preheating wheel 7. The output preheating wheel 7 preheats the corrugated paper and outputs it to reduce the moisture in the corrugated paper.
