[0002] Corrugated paper is a board-shaped material made by gluing noodle paper and corrugated paper formed by corrugating rollers. It is generally divided into two categories: single corrugated paperboard and double corrugated paperboard. According to the size of the corrugation, it is divided into five types: A, B, C, E, and F. The invention and application of corrugated paper has a history of more than 100 years. It has the advantages of low cost, light weight, easy processing, high strength, excellent printing adaptability, and convenient storage and transportation. More than 80% of corrugated paper can be recycled. Corrugated paper can be used as packaging for food or digital products. It is relatively environmentally friendly and widely used. In the production process of recycled corrugated paper, the pulp needs to be filtered and concentrated, and a pulp filtration mechanism is needed at this time.

[0003] Existing pulp filtering mechanisms for recycled corrugated paper production usually use a filter drum to rotary filter the pulp, and there is still moisture remaining in the filtered pulp, so the filtering effect on the pulp is not good.

[0023] Specifically, the inner wall of the filter screen cylinder 2 is arranged with spiral guide blades 201, and a through hole 202 is opened in the center of one end of the filter screen cylinder 2 facing the feed hopper 3. With the cooperation of the spiral guide blades 201, pulp can be guided from one end to the other end. The through hole 202 is convenient for adding corrugated paper pulp.

[0024] Furthermore, a material guide pipe 301 is arranged at the bottom of the feed hopper 3 , and one end of the material guide pipe 301 passes through the through hole 202 . The feed hopper 3 flows into the filter screen cylinder 2 with the cooperation of the material guide pipe 301 .

The first servo motor 401 drives the gear plate 402 to rotate, and then the gear plate 402 cooperates with the gear sleeve 403 to drive the filter screen cylinder 2 to rotate.

[0026] In a specific embodiment, a triangular seat 5 is arranged at one end of the mounting seat 1 facing away from the feed hopper 3, the inner cavity of the triangular seat 5 is communicated with the inner cavity of the mounting seat 1, a filter hole is arranged on the top surface of the triangular seat 5, a side plate structure 6 is arranged on the front and rear sides of the top of the triangular seat 5, and two groups of symmetrical pressing rollers 8 are rotatably arranged between the two groups of side plate structures 6 through bearings, and a second servo motor 7 corresponding to the pressing roller 8 is installed on the side plate structure 6, and the rotating shaft at the output end of the second servo motor 7 is fixedly connected to one end of the corresponding pressing roller 8; specifically, a convex strip 801 is arranged on the surface of the pressing roller 8, and the convex strip 801 It is in a triangular shape. The corrugated paper pulp after being filtered by the filter cylinder 2 will fall onto the triangular seat 5, and then the second servo motor 7 is controlled to drive the pressing roller 8 to rotate. At this time, the convex strip 801 on the pressing roller 8 will drive the corrugated paper pulp to move below the pressing roller 8. When the corrugated paper pulp passes through the pressing roller 8, the pressing roller 8 cooperates with the inclined surface of the triangular seat 5 to squeeze and filter the corrugated paper pulp. The squeezed water will directly enter the inner cavity of the triangular seat 5 through the filter hole on the top of the triangular seat 5, thereby realizing the secondary squeezing and filtering of the corrugated paper pulp, ensuring sufficient filtration of the water in the pulp.

The T-shaped mounting rods 602 are mounted with a top plate 603. The pressure roller 8 and the second servo motor 7 are both arranged on the top plate 603. The T-shaped mounting rods 602 penetrate the top part of the top plate 603 and are mounted with springs 604.

[0028] Working principle: When filtering corrugated paper pulp, first, the corrugated paper pulp is added to the feed hopper 3, and then the corrugated paper pulp enters the filter screen cylinder 2 through the guide pipe 301 of the feed hopper 3. At this time, the filter screen cylinder 2 is driven to rotate by the driving structure 4. During the rotation of the filter screen cylinder 2, the moisture in the corrugated paper pulp is filtered out, and the filtered moisture falls into the inner cavity of the mounting seat 1 for storage. The filtered paper pulp is discharged from the open end of the filter screen cylinder 2, and the filtering operation of the corrugated paper pulp is completed;

[0029] Secondly, the corrugated paper pulp after being filtered by the filter cylinder 2 will fall onto the triangular seat 5, and then the second servo motor 7 is controlled to drive the pressing roller 8 to rotate. At this time, the convex strip 801 on the pressing roller 8 will drive the corrugated paper pulp to move below the pressing roller 8. When the corrugated paper pulp passes through the pressing roller 8, the pressing roller 8 cooperates with the inclined surface of the triangular seat 5 to squeeze and filter the corrugated paper pulp. The squeezed water will directly enter the inner cavity of the triangular seat 5 through the filter hole at the top of the triangular seat 5, thereby realizing secondary squeezing and filtering of the corrugated paper pulp, ensuring sufficient filtration of the water in the paper pulp;

[0030] Finally, the top plate 603 can be displaced on the T-shaped mounting rod 602, so that when a large amount of corrugated paper pulp passes through the bottom of the pressing roller 8, the pressing roller 8 can be automatically lifted and the height can be adjusted. Pushed by the spring 604, the pressing roller 8 can have a sufficient squeezing effect on the passing corrugated paper pulp. Therefore, the pressing roller 8 can automatically adjust its height according to the amount of corrugated paper pulp passing through, while ensuring the rolling effect of the pressing roller 8 on the corrugated paper pulp, thereby improving the adaptability of the pressing roller 8.
