Description

Technical Field

[0001] This utility model relates to the field of papermaking machinery technology, and in particular to a self-cleaning papermaking machine. Background Technology

[0002] Early equipment mainly relied on mechanical pulping of wood and the grinding process, resulting in paper with low strength and a tendency to yellow. In the 20th century, chemical pulping technology matured, and the sulfate and sulfite processes became widespread, solving the problem of lignin residue. The brightness and stability of pulp were significantly improved. The demand for large-scale industrial production spurred the development of paper machines towards higher speeds and wider widths, with continuous breakthroughs in machine speed and width, resulting in a significant increase in production efficiency.

[0017] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0018] Reference Figure 1-5 This utility model discloses a self-cleaning paper machine, which includes a main frame 1. Two rows of symmetrical rollers 3 are arranged on the inner side of the main frame 1. A dry wire 2 is slidably connected and fixed on the surface of the rollers 3. A water tank 7 is arranged above the main frame 1. An annular water pipe 8 is fixedly connected to the bottom of the water tank 7. Several water spray heads 9 are fixedly connected to the upper and lower sides of the annular water pipe 8. A first box 17 is arranged in front of the main frame 1. An intercepting grid 20 is fixedly connected to the inner side of the first box 17. A second box 12 is arranged in front of the main frame 1. A drying box 24 is fixedly connected to the rear side of the main frame 1. A secondary frame 35 is fixedly connected to the rear side of the drying box 24.

[0019] Specifically, the function of the dry wire 2 is to help the pulp set after it is sprayed from the nozzle 10, and to control the moisture content in the new paper through the squeezing action of the roller 3. The dry wire 2 is woven from high hydrolysis resistant polyester monofilament, which has the characteristics of being resistant to acid, alkali, high temperature and wear, and has a service life far longer than traditional ones. It is used in the production of cultural paper, paperboard, corrugated paper, etc., and has a wide range of air permeability adjustment.

[0020] A first motor 19 is fixedly connected to the top of the first housing 17. A rotating shaft 21 is fixedly connected to the output end of the first motor 19. Four blades 22 are evenly fixedly connected to the bottom of the rotating shaft 21. A feed inlet 18 is fixedly connected to the top of the first housing 17. A conveying pipe 16 is fixedly connected to the lower outer side of the first housing 17.

[0021] Specifically, the first chamber 17 is used for pickling, and its interior mainly contains diluted sulfuric acid. The purpose of pickling is to: adjust the pH value: after the pulp has undergone cooking, bleaching and other preliminary processes, it may be alkaline. Pickling can reduce the pH value of the pulp by adding acidic substances to meet the process requirements; remove impurities: some metal ions or alkaline substances may remain in the pulp. The acidic solution can react chemically with some impurities to form soluble substances or precipitates, which can be removed by washing; improve pulp performance: appropriate pickling can adjust the fiber morphology of the pulp, reduce excessive bonding between fibers, and improve the air permeability and softness of the paper. Substances that cannot be removed are thrown to the intercepting grid 20 by the high-speed rotation of the paddle 22 through centrifugal force and are intercepted, while the pulp enters the next stage due to its flexibility.

[0022] A second motor 15 is fixedly connected to the outside of the second housing 12. A spiral shaft 13 is fixedly connected to the output end of the second motor 15. A spiral cutter head 14 is fixedly connected to the outer surface of the spiral shaft 13. A guide pipe 11 is fixedly connected to one side of the opening of the second housing 12. A nozzle 10 is fixedly connected to the other end of the guide pipe 11.

[0023] Specifically, the spiral cutter head 14 can further break down the pulp, shorten the wood fibers of the pulp through kneading, and transport the pulp to the next process.

[0024] The drying oven 24 has two rows of rollers 26 that are fixedly and evenly installed inside, and paper mesh 27 is fixedly and slidably connected between the rollers 26. An observation port 25 is fixedly and embedded in the side of the drying oven 24.

[0025] The paper wire 27 has the primary paper produced in the previous stage attached to it. The roller 26 allows the paper to stay in the drying chamber 24 for a longer time, which is conducive to the full drying of the paper. The drying chamber 24 uses hot air drying. Its principle is: the blower blows heated air onto the surface of the paper, and the temperature difference between the air and the paper and the airflow remove moisture. It is suitable for tension-sensitive paper and can reduce paper stretching and deformation.

[0026] Two rows of symmetrical rolling cylinders 28 are slidably fixed inside the sub-frame 35.

[0027] Specifically, the rolling cylinder 28 is made of metal with a smooth surface and a large mass, which can make the paper surface smoother after rolling.

[0028] A paper roll 33 is fixedly connected to the rear side of the sub-frame 35, and a fifth motor 34 is fixedly connected to the central shaft of the paper roll 33.

[0029] Specifically, the paper roll 33 is mainly used for winding up the finished paper.

[0030] A third motor 23 is fixedly connected to the outside of the main frame 1. A first driving wheel 4 is fixedly connected to the output end of the third motor 23. A first driven wheel 6 is located directly below the first driving wheel 4. A first belt 5 is slidably and fixedly connected between the outside of the first driven wheel 6 and the outside of the first driving wheel 4.

[0031] Specifically, the third motor 23 is the power source for the rotation of the roller 3.

[0032] A fourth motor 32 is fixedly connected to the outer side of the sub-frame 35. A second drive wheel 29 is fixedly connected to the output end of the fourth motor 32. A second driven wheel 30 is located directly below the second drive wheel 29. A second belt 31 is slidably and fixedly connected between the outer side of the second driven wheel 30 and the outer side of the second drive wheel 29.

[0033] Specifically, the fourth motor 32 is the power source for the rolling cylinder 28.

[0034] Working principle: The raw pulp enters the first box 17 through the feed port 18. After being acid-soaked to remove impurities, it enters the second box 12. After being crushed by the spiral cutter head 14 in the second box 12, it enters the guide pipe 11 for pressurization. The pulp is sprayed out through the nozzle 10. After being extruded and shaped by the main frame 1, it enters the drying box 24 for drying. After being rolled by the roller 28, it is wound up by the paper roll 33.

[0035] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
