Description

Technical Field

[0001] This utility model relates to the field of corrugated paper extrusion molding technology, and in particular to a corrugated paper forming extrusion device. Background Technology

[0002] Corrugated paper is a sheet-like material made by bonding linerboard and corrugated paper that has been processed by corrugating rollers. It has a wide range of applications and is often used to make corrugated boxes. It has the characteristics of being lightweight and sturdy. Forming and extrusion equipment is required when producing corrugated paper.

[0003] During the process of extruding pulp into corrugated paper, some pulp inevitably sticks to the pressure rollers. If not cleaned for a long time, more and more paper scraps will accumulate on the pressure rollers. After the paper scraps clump together, they will squeeze small holes into the surface of the corrugated paper, making the surface of the corrugated paper pitted and uneven, which greatly affects the forming quality of the corrugated paper. Existing extrusion equipment requires the machine to be stopped before cleaning the paper scrap clumps. This operation is time-consuming, affecting the production efficiency and quality of corrugated paper, and requires multiple shutdowns for cleaning, which is extremely inconvenient.

[0004] In view of the technical problems existing in the prior art, this utility model provides a corrugated paper forming and extrusion device to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a corrugated paper forming and extrusion device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A corrugated paper forming and extrusion device includes a housing. A discharge port and a feed port are respectively provided on both side walls of the housing, with the openings of the discharge port and the feed port corresponding to each other. A first telescopic rod is fixedly installed on the inner top surface of the housing near the discharge port, and a second telescopic rod is fixedly installed on the inner bottom surface of the housing directly below the first telescopic rod. First pressure rollers are rotatably connected to the telescopic ends of both the first and second telescopic rods. Two second pressure rollers are rotatably connected between the two inner side walls of the housing near the feed port, with one second pressure roller positioned below the other. Directly below, an installation plate is fixedly installed on the inner bottom surface of the box. The installation plate is located between the first pressure roller and the second pressure roller. An installation box is fixedly installed on the side wall of the installation plate near the second pressure roller. Multiple springs are fixedly installed on the inner side wall of the installation box. The multiple springs are arranged linearly. A connecting rod is fixedly installed on one end of each of the multiple springs. One end of each of the multiple connecting rods passes through the side wall of the installation box and is fixedly installed with the same second scraper. One end of the second scraper is adapted to the outer ring surface of the second pressure roller, and one end of the second scraper abuts against the adjacent second pressure roller.

[0008] Preferably, a groove is provided on the inner bottom surface of the box, and a second collection box is slidably installed in the groove.

[0009] Preferably, the chute is located directly below the second pressure roller, and the length of the second collection box is greater than the length of the second pressure roller.

[0010] Preferably, the top of the box body has a rectangular hole located above the second pressure roller, and a connecting seat is provided in the rectangular hole. The connecting seat is T-shaped.

[0011] Preferably, a first collection box is fixedly installed at the bottom of the connecting seat, and a first scraper is fixedly installed at the opening of the first collection box.

[0012] Preferably, one end of the first scraper and the bottom end of the first collection box are adapted to the outer ring surface of the adjacent second pressure roller, and the top end of the connecting seat is adapted to the rectangular hole.

[0013] Compared with the prior art, the advantages of this utility model are as follows:

[0014] 1. This utility model, by setting a connecting seat, rectangular hole, first collection box, first scraper, second pressure roller, slide groove, second collection box and second scraper, can promptly scrape off the waste on the two second pressure rollers by the scraper in conjunction with the rotation of the second pressure roller without stopping the machine. It is extremely convenient, improves the production efficiency of the equipment, and ensures that the surface of the corrugated paper remains flat without the influence of paper scraps, thus improving the quality of the produced corrugated paper.

[0015] 2. This utility model, by setting up an installation plate, installation box, spring and connecting rod, eliminates the need for manual adjustment of the scraper position. Under the action of the spring, the second scraper will be tightly attached to the pressure roller, making operation simple and easy, and more flexible. Attached Figure Description

The second scraper 18 abuts against the adjacent second pressure roller 10 under the action of multiple springs 16. Adjust the extension length of the first telescopic rod 3 and the second telescopic rod 5 to ensure that the tension of the corrugated paper is within the normal range. Then start the independent motor to perform the extrusion molding operation. The paper scraps attached to the two second pressure rollers 10 are scraped off by the first scraper 9 and the second scraper 18 and enter the first collection box 8 and the second collection box 13. Clean the first collection box 8 and the second collection box 13 regularly.
