[0002] During the paper production process, the raw paper itself contains moisture and adhesives, which require drying cylinders to dry the raw paper.

[0003] During the drying process, moisture and adhesives on the raw paper adhere to the surface of the drying cylinder, accumulating and thickening, which affects the drying efficiency of the raw paper. Usually, a scraper is set on the outer surface of the drying cylinder to remove the impurities attached to the surface of the drying cylinder. However, the existing scrapers are difficult to adjust, and after a period of use, the pressure on the scraper is easily reduced, which in turn leads to a poor scraping effect.

[0004] Meanwhile, most of the impurities scraped off by the existing scrapers fall directly to the ground, and the impurities scattered on the ground are difficult to clean up. Utility Model Content

[0005] To address the aforementioned shortcomings, the purpose of this invention is to provide a paper forming uniform drying device that can uniformly dry the raw paper, promptly scrape off impurities adhering to the drying cylinder to prevent impurities from affecting the drying of the raw paper, and adjust the clamping force on the scraper by setting the adjusting bolt to avoid the problem of poor scraping effect due to the inability to adjust after the clamping force decreases; the setting of the limiting rod can limit the adjusting bolt to prevent the adjusting bolt from loosening due to the vibration of the scraper; the setting of the guide trough can guide the impurities to one side, making it convenient for workers to clean the impurities scraped off by the scraper.

[0006] To achieve the above objectives, this utility model provides a paper forming uniform drying device, including a rotatable drying cylinder, a mounting frame on one side of the drying cylinder, a scraper for cleaning the drying cylinder between the mounting frame and the drying cylinder, and several adjustment devices between the mounting frame and the scraper.

Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely for explaining the present utility model and are not intended to limit the present utility model.

[0022] See Figures 1-6 This utility model provides a paper forming uniform drying device, which includes a rotatable drying cylinder 1 (e.g., Figure 1 As indicated by the arrow, the drying cylinder 1 rotates clockwise. The surface of the drying cylinder 1 contacts the surface of the raw paper to dry it. A mounting frame 2 is provided on one side of the drying cylinder 1. A scraper 15 for cleaning the drying cylinder 1 is provided between the mounting frame 2 and the drying cylinder 1. The mounting frame 2 is used to install the scraper 15. The mounting frame 2 is located on one side of the drying cylinder 1 and extends along the axial direction of the drying cylinder 1. The mounting frame 2 is rotatably connected to the bottom end of the scraper 15. One end of the scraper 15 with a blade abuts against the lower right end of the drying cylinder 1. The scraper 15 can rotate on the mounting frame 2 to ensure that the scraper 15 always keeps in contact with the surface of the drying cylinder 1. The scraper 15 is used to scrape off impurities on the surface of the drying cylinder 1 to prevent impurities from affecting the drying effect.

[0023] Mounting bracket 2 is equipped with several adjustment devices. These devices can adjust the clamping force of the scraper 15 against the surface of the drying cylinder 1, preventing the clamping force of the scraper 15 from decreasing after a period of use, thus avoiding a reduction in scraping effect. The adjustment device includes a first elastic element 11. When compressed, the first elastic element 11 can apply pressure to the scraper 15, thereby facilitating a certain clamping force between the scraper 15 and the drying cylinder 1. One end of the first elastic element 11 is fixedly connected to one side of the scraper 15, and the other end is fixedly connected to a sliding plate 16. The sliding plate 16 can slide away from or towards the scraper 15, thereby achieving clamping of the first elastic element 11. The sliding plate 16 is slidably connected to a guide cylinder 14, which guides the sliding plate 16 and restricts its rotation. The guide cylinder 14 is fixedly connected to the mounting bracket 2.

[0024] The sliding plate 16 is rotatably connected to one end of the adjusting bolt 7, which is threadedly connected to the mounting bracket 2. Rotation of the adjusting bolt 7 adjusts the position of the sliding plate 16 on the guide cylinder 14, thereby facilitating the adjustment of the clamping force on the scraper 15. The other end of the adjusting bolt 7 is fixedly connected to the limiting disc 9, which is slidably connected to the limiting rod 8. The mounting bracket 2 has several limiting holes 6 evenly distributed circumferentially. The limiting rod 8 is equipped with a second elastic element 13. The limiting rod 8, in conjunction with the limiting holes 6, restricts the rotation of the adjusting bolt 7, preventing vibration of the scraper 15 from causing the adjusting bolt 7 to rotate and thus preventing it from loosening. The second elastic element 13 provides a restoring pull for the limiting rod 8, preventing it from disengaging from the limiting holes 6 without manual intervention, thus preventing limiting failure.

[0025] See Figures 2-6 Furthermore, the guide cylinder 14 of this utility model is sleeved on the outside of the sliding plate 16, and the guide cylinder 14 has a space inside for the sliding plate 16 to slide. The limiting holes 6 are symmetrically arranged in pairs, and there are two limiting rods 8 symmetrically arranged about the adjusting bolt 7. The two limiting rods 8 can better limit the adjusting bolt 7 and prevent the adjusting bolt 7 from rotating. The ends of the two limiting rods 8 are connected by a connecting rod 10. One end of the second elastic member 13 is fixedly connected to the center position of the limiting plate 9, and the other end of the second elastic member 13 is fixedly connected to the center of the connecting rod 10. The second elastic member 13 is used to pull the connecting rod 10 back to its original position to prevent the limiting rod 8 from sliding out of the limiting hole 6.

[0026] See Figure 1 , Figure 3 , Figure 4 , Figure 5Furthermore, the mounting frame 2 of this utility model is provided with a discharge hole at the bottom, and a first baffle plate 3 is fixedly connected to the top of the mounting frame 2. Second baffle plates 4 are fixedly connected to both ends of the mounting frame 2 respectively. The cooperation of the first baffle plate 3 and the second baffle plate 4 can prevent impurities from splashing and reduce the difficulty of cleaning. A guide groove 5 extending along the axial direction of the drying cylinder 1 is provided at the bottom of the mounting frame 2. The bottom surface of the guide groove 5 is inclined, which allows impurities to slide easily under the action of gravity, facilitating the guidance of impurities to one side of the guide groove 5. An outlet 12 is provided at the lower end of the bottom surface of the guide groove 5, which facilitates the discharge of impurities accumulated at the outlet 12, making it convenient for workers to clean the impurities. At least three adjusting devices are evenly arranged. These three evenly arranged adjusting devices can better adjust the scraper 15, preventing the scraper 15 from being unable to provide sufficient pressure when the scraper 15 is long, even if only one or two adjusting devices are used.

[0027] See Figure 2 , Figure 4 Specifically, both the first elastic element 11 and the second elastic element 13 are springs.

[0028] In summary, this utility model provides a paper forming uniform drying device, including a rotatable drying cylinder. When the raw paper passes through the drying cylinder, it comes into contact with the surface of the cylinder, and the drying cylinder is used to dry the raw paper. A mounting frame is provided on one side of the drying cylinder, which is used to mount a scraper, providing support for the scraper and other components. A scraper for cleaning the drying cylinder is provided between the mounting frame and the drying cylinder. The scraper can remove impurities adhering to the surface of the drying cylinder, preventing impurities from accumulating on the surface. Several adjusting devices are provided between the mounting frame and the scraper, which can adjust the clamping force of the scraper against the surface of the drying cylinder, preventing the scraper from wearing out and causing damage. The effect of removing impurities is weakened; the adjustment device includes a first elastic element, one end of which is fixedly connected to one side of the scraper, and the other end of which is fixedly connected to a sliding plate. The sliding plate is slidably connected inside the guide cylinder, and the guide cylinder is fixedly connected to the mounting bracket. The end of the sliding plate away from the scraper is rotatably connected to an adjusting bolt threaded to the mounting bracket. Adjusting the position of the sliding plate can adjust the elastic force of the first elastic element, preventing the pressure provided by the first elastic element to the scraper from decreasing. The guide can prevent the sliding plate from rotating, and the setting of the adjusting bolt can facilitate the adjustment of the position of the sliding plate, further facilitating the adjustment of the pressure of the first elastic element on the scraper.
