Description

Technical Field

[0001] The utility model relates to the technical field of papermaking scraping glue, in particular to a papermaking scraping glue mechanism. Background Art

[0002] Papermaking refers to the process of making various types of paper. The raw materials for papermaking include wood, reed, bagasse, straw, wheat straw, cotton straw, hemp stalks, cotton, etc. During the papermaking process, coating, glazing, gluing, lamination and other processes are required. Gluing is to apply glue to the pulp to enhance the waterproof effect and strength of the paper, while the scraper mechanism is an important equipment used to remove excess water, glue and some impurities on the pulp after gluing the paper.

[0003] After searching, the patent number "CN209602869U" mentioned "a papermaking scraping mechanism, which includes a degumming groove, a front adjustment plate and a rear adjustment plate. By arranging the front adjustment plate and the rear adjustment plate on the front side and the groove body of the degumming groove respectively, the cardboard passes through the upper side of the front adjustment plate and the rear adjustment plate, and the front adjustment plate rotates and tilts toward the groove body, and the rear adjustment plate swings to scrape glue, and glue residue is stored in the groove body." When it is in use, the adjustment plate scrapes glue on the paper, and when the paper is produced, its thickness and glue amount are different. The fixed scraper plate cannot adjust the position and scraping speed according to different situations of paper, resulting in different amounts of glue left on papers of different thicknesses. It is also difficult to manually adjust the position of the scraper plate according to the thickness of different papers, which easily leads to differences in the quality of the final paper product.

[0004] To this end, we provide a papermaking scraping mechanism to solve the above problems. Utility Model Content

[0005] The present application provides a papermaking scraper mechanism, which solves the problem mentioned in the above background technology that the scraper plate cannot be adjusted according to the position of papers of different thicknesses, and it is difficult to manually adjust the position of the scraper plate according to the thickness of papers of different thicknesses, which easily leads to differences in the quality of the final finished paper.

[0006] The present application provides a papermaking scraping mechanism, comprising a shell and a scraping mechanism, wherein the scraping mechanism is arranged inside the shell;

[0007] The scraper mechanism comprises a pre-treatment scraper assembly arranged inside the shell, a driving assembly is arranged below the pre-treatment scraper assembly, a scraper assembly is arranged below the driving assembly, and a pressure control assembly is arranged inside the scraper assembly.

[0008] Preferably, the pre-treatment scraper assembly comprises a first scraper plate installed on the inner side of the shell, and a glue guiding groove is formed on the upper surface of the first scraper plate.

[0009] Preferably, the driving assembly comprises a driving roller installed below the first scraper plate, and a servo motor is fixedly connected to the right end of the driving roller.

[0010] Preferably, the scraper assembly includes a second scraper connecting plate arranged on the lower side of the driving roller, a scraper head is arranged on the inner side of the second scraper connecting plate, the left end of the second scraper connecting plate is fixedly connected to a driving connecting rod, and the left and right key slots of the driving connecting rod are connected to a rotating motor.

[0011] Preferably, the rubber scraper head is connected to the second rubber scraper connecting plate by a slot, and the rubber scraper head is made of rubber.

[0012] Preferably, the pressure control component includes a pressure sensor installed between the scraper head and the second scraper connecting plate, the lower side of the rotating motor is electrically connected to a rotation controller, and the pressure sensor and the rotation controller are electrically connected.

[0013] Preferably, a drive control component is provided on the inner side of the first scraper plate, and the drive control component includes a humidity sensor installed on the inner side of the first scraper plate, and the lower end of the servo motor is electrically connected to a drive controller, and the humidity sensor and the drive controller are electrically connected.

[0014] It can be seen from the above technical scheme that the present application provides a papermaking glue scraping mechanism, which performs preliminary glue scraping treatment on the paper through a first glue scraping plate to remove excess glue on the paper, and at the same time, the excess glue can be collected through the glue guide groove, and then the servo motor is started to drive the driving roller to rotate inward, driving the paper to move downward, and at the same time, the paper can be flattened and the glue can be evenly spread, and then the paper is subjected to secondary glue scraping treatment through the glue scraping head, and at the same time, the second glue scraping connecting plate can be driven to rotate by rotating the motor, thereby adjusting the gap between the glue scraping heads, which is convenient for scraping glue on papers of different thicknesses. When scraping glue, the pressure of the scraper head on the paper is detected by the pressure sensor. When the pressure exceeds the preset threshold, the rotation controller will control the rotation motor to rotate, adjust the angle of the second scraper connecting plate, and increase the gap between the scraper heads to reduce the pressure on the paper. Finally, the humidity of the paper is detected by the humidity sensor to judge the glue content of the paper. When it is detected that the glue content is high, the drive controller can be used to control the servo motor to reduce the speed of the drive roller and slow down the scraping speed to ensure that the excess glue can be completely removed and the uniformity of the glue on the paper surface is improved.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] 1. Through the setting of the protective component, the humidity of the paper is detected by the humidity sensor, so as to judge the glue content of the paper. When the glue content is detected to be high, the servo motor can be controlled by the drive controller to reduce the speed of the drive roller and slow down the scraping speed to ensure that the excess glue can be completely removed and the uniformity of the glue on the paper surface can be improved;

[0017] 2. Through the setting of the scraping mechanism, the paper is initially scraped with the first scraper plate to remove excess glue on the paper. At the same time, the excess glue can be collected through the glue guide groove, and then the servo motor is started to drive the driving roller to rotate inward, drive the paper to move downward, and also can flatten the paper and spread the glue evenly. Then the paper is scraped with the scraper head for the second time, and the second scraper connecting plate can be driven to rotate by the rotating motor, so as to adjust the gap between the scraper heads, so as to facilitate the scraping of papers of different thicknesses. When scraping the glue, the pressure of the scraper head on the paper is detected by the pressure sensor. When the pressure exceeds the preset threshold, the rotation controller will control the rotation motor to rotate, adjust the angle of the second scraper connecting plate, increase the gap between the scraper heads, so as to reduce the pressure on the paper. At the same time, the rubber scraper head can fit the paper surface better when scraping the glue on the paper, and avoid the paper from being scratched, thereby improving the scraping effect.

[0018] To summarize, the present application sets up a scraping mechanism so that the device can automatically change the pressure angle of the scraper plate and the scraping rate when processing papers of different thicknesses and glue contents, thereby ensuring the uniformity of the quality of the finished paper after scraping, thereby improving the stability of the paper quality.
