Description

Technical Field

[0001] The utility model relates to the technical field of paper machines, in particular to a wire part water filtration and forming mechanism of a paper machine. Background Technique

[0002] A paper machine is a device used to convert pulp into paper, mainly consisting of steps such as pulp preparation, wire part treatment, pressing and drying, surface treatment, coiling and cutting, etc. Among them, the wire part treatment is the key to determining the thickness and quality of the paper. The wire part treatment mainly sprays the pulp onto the forming wire, and the water in the pulp drains downward through the mesh holes of the forming wire, while the fibers remain on the forming wire to form a paper web, and then steps such as squeezing out water and drying and winding are carried out.

[0003] When the pulp forms a paper web, it is necessary to initially drain the pulp on the pulp fishing filter plate through a forming roller, so that the pulp on the pulp fishing filter plate forms a paper web with a relatively high water content and causes the paper web to have a certain coherence, and then it is convenient for subsequent processing such as draining water and drying of the paper web. During this process, due to the relatively large water content of the initially formed paper web, the paper web is likely to adhere to the forming roller, and the paper web is easily broken due to the rotation of the forming roller. Moreover, some fibers in the pulp adhering to the forming roller will affect the forming of the paper web, resulting in uneven thickness of the initially formed paper web. In addition, when the pulp is initially drained by being squeezed by the forming roller, since the pulp has not yet formed a paper web at this time, the pulp is likely to generate corrugations, which will form wrinkles on the initially formed paper web, thus affecting the quality of the paper. Summary of the Utility Model

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0035] Please refer to Figures 1 - 4 , a net part water filtering and forming mechanism of a paper machine, including a bottom plate 1. On the left side of the top surface of the bottom plate 1, a fixed plate 2 is fixedly installed. On the upper part of the left side surface of the fixed plate 2, a pulp inlet pipe 3 is fixedly installed. At the corresponding position of the upper part of the right side surface of the pulp inlet pipe 3, a pulp inlet trough 4 is fixedly installed. On the top surface of the bottom plate 1, on the right side of the fixed plate 2, a pulp scooping pool 5 is fixedly installed. Inside the pulp scooping pool 5, a pulp scooping filter plate 6 is fixedly installed. On the inner side wall of the pulp scooping pool 5, above the pulp scooping filter plate 6, a pulp scraping plate 7 is fixedly installed. On the top surface of the bottom plate 1, on the right side of the pulp scooping pool 5, a driving roller 8 is rotatably installed through a support frame. A pulp conveyor belt 9 is sleeved on the driving roller 8. On the top surface of the bottom plate 1, above the pulp conveyor belt 9, a forming roller 10 is rotatably installed through a support frame. On the top surface of the bottom plate 1, on the right side of the driving roller 8, a squeezing roller 11 is rotatably installed through a support frame. On the top surface of the bottom plate 1, on the right side of the squeezing roller 11, a winding roller 12 is rotatably installed through a support frame. On the top surface of the bottom plate 1, on the right side of the pulp scooping pool 5, a water pool 13 is fixedly installed. The water pool 13 is located below the driving roller 8, the pulp conveyor belt 9, the forming roller 10 and the squeezing roller 11.

[0036] Please refer to Figures 1 - 4 , on the upper part of the right side wall of the support frame where the forming roller 10 is located, a fixing block 100 is fixedly welded. In the middle of the right side surface of the fixing block 100, a connecting frame 101 is fixedly welded.

[0037] Please refer to Figures 1 - 4, a mounting rod 102 is fixedly connected to the middle of the connecting frame 101. A scraping plate 103 is fixedly sleeved on the outer surface of the mounting rod 102. One end of the scraping plate 103 away from the mounting rod 102 contacts the outer surface of the forming roller 10, ensuring that the scraping plate 103 can peel off the paper web attached to the forming roller 10, preventing the initially formed paper web from breaking under the influence of the rotation of the forming roller 10 after adhering to the forming roller 10.

[0038] Please refer to Figures 1 - 4 , on the upper part of the left side wall of the support frame where the forming roller 10 is located, a fixed frame 104 is fixedly welded. In the middle of the fixed frame 104, a support plate 105 is fixedly welded. A regulating block 106 is arranged below the support plate 105.

[0039] Please refer to Figures 1 - 4 , a sliding rod 107 is fixedly connected to the bottom surface of the regulating block 106. One end of the sliding rod 107 away from the regulating block 106 is fixedly welded with an arc-shaped plate 108, ensuring that a gap can be formed between the arc-shaped plate 108 and the pulp conveyor belt 9. When the pulp passes through the arc-shaped plate 108, the arc-shaped plate 108 can make the pulp spread out flat on the pulp conveyor belt 9, preventing the pulp from having corrugations when passing through the forming roller 10.

[0040] Please refer to Figures 1 - 4 , a spring 109 is sleeved on the outer side of the sliding rod 107 at the bottom surface of the regulating block 106. The upper end of the spring 109 is fixedly connected to the bottom surface of the regulating block 106, and the lower end of the spring 109 is fixedly connected to the top surface of the arc-shaped plate 108. A regulating bolt 110 is connected to the middle of the support plate 105 through screw threads. The bottom end of the regulating bolt 110 is fixedly welded to the top surface of the regulating block 106, ensuring that the regulating block 106 can be adjusted by rotating the regulating bolt 110, thereby adjusting the distance between the arc-shaped plate 108 and the pulp conveyor belt 9 to ensure that the equipment can produce paper of different thicknesses.

[0041] Working principle: After the pulp enters the pulp inlet tank 4 through the pulp inlet pipe 3, the pulp will enter the pulp scooping pool 5, and the pulp fibers will stay on the pulp scooping filter plate 6. Then, the pulp is transported by the pulp conveyor belt 9, so that the pulp is transported to the forming roller 10, causing the pulp to initially form a paper web. The initially formed paper web will pass through the squeezing roller 11 and then be wound on the winding roller 12. The wastewater squeezed by the squeezing roller 11 is directly collected by the water tank 13. During this process, when the pulp is transported to the forming roller 10 by the pulp conveyor belt 9 for extrusion forming processing, since the scraping plate 103 contacts the outer surface of the forming roller 10, when the forming roller 10 rotates, the paper web attached to the outer surface of the forming roller 10 will be peeled off by the scraping plate 103, preventing the initially formed paper web from adhering to the forming roller 10 and preventing the paper web from being broken due to the rotation of the forming roller 10. Moreover, the scraping plate 103 can also scrape off the fibers attached to the forming roller 10 to prevent the fibers from adhering to the forming roller 10 and affecting the uniformity of the paper web forming. At the same time, after the pulp transitions from the pulp scooping filter plate 6 to the pulp conveyor belt 9, due to the setting of the arc plate 108, the arc plate 108 will contact the pulp on the pulp conveyor belt 9 under the potential energy action of the spring 109, so that the pulp on the pulp conveyor belt 9 will be scraped flat by the arc plate 108, prompting the pulp to be laid flat on the pulp conveyor belt 9, effectively preventing the pulp from forming corrugations when passing through the forming roller 10 and improving the quality of the paper. Secondly, the distance between the arc plate 108 and the pulp conveyor belt 9 can be adjusted by rotating the adjusting bolt 110 to make the adjusting block 106 move up or down, which can adapt to the production of papers with different thicknesses and improve the applicability of the paper machine.
