Description

Technical Field

[0001] This utility model relates to the field of papermaking equipment technology, specifically to a paper peeling blade that facilitates dust removal. Background Technology

[0002] In the papermaking process, after the paper is dried in the drying cylinder, it needs to be separated by a precise action between a peeling blade and the surface of the drying cylinder. This step directly affects the paper's forming quality and production continuity. Currently, peeling blades are widely used in the industry to complete the paper separation.

[0003] However, in actual production, the paper peeling process is often accompanied by dust generation. Specifically, when the blade contacts the surface of the drying cylinder and peels the paper, the release of the adhesive force between the paper and the drying cylinder, as well as the friction between the blade, the paper, and the drying cylinder, causes paper surface fibers to fall off and local paper layers to break. At the same time, fine impurities remaining on the surface of the drying cylinder are also scraped off. These detached materials together form a large amount of dust. Driven by the airflow generated by the peeling action, this dust will directly splash and spread into the surrounding environment, causing pollution to the site. Utility Model Content

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0023] This embodiment provides a paper peeling blade that facilitates dust removal, such as... Figures 1 to 6 As shown, it includes a support frame 1 and a peeling device 2. The support frame 1 is equipped with a drive device 10, and the peeling device 2 is connected to the drive device 10 in a transmission manner. The peeling device 2 is used to peel the paper from the drying cylinder. Peeling the paper from the drying cylinder is a prior art technique, and for details, please refer to paragraph 0028 of the specification of Chinese Utility Model Patent Publication No. CN215448181U.

[0024] Furthermore, the peeling device 2 includes two spaced-apart mounting plates 20, which are respectively fixedly connected to the drive device 10. A connecting rod 21 is rotatably provided between the two mounting plates 20, and a peeling blade 22 is fixedly provided on the connecting rod 21.

[0025] The peeling blade 22 has perforations 220 arranged along its thickness direction. Multiple perforations 220 are arranged laterally at intervals along the length of the peeling blade 22. A dust box 23 is located at the bottom of the peeling blade 22, covering all the perforations 220 and hinged to the bottom of the peeling blade 22. This design allows for efficient dust removal. When the peeling blade 22 peels the paper from the drying cylinder, the previously tight adhesion between the paper and the cylinder is rapidly released at the moment of peeling. Simultaneously, friction inevitably occurs between the blade of the peeling blade 22 and the paper surface and the outer wall of the drying cylinder, causing fiber shedding from the paper surface and partial breakage of some fragile paper layers. This generates a large amount of dust. The perforations 220 on the peeling blade 22 provide a flow channel for this dust. Driven by gravity and the airflow generated during peeling, the dust flows smoothly into the dust box 23 below through the perforations 220, effectively preventing dust from splashing and polluting the working environment. In addition, since the dust box 23 is hinged to the bottom of the stripping blade 22, when the dust collected in the dust box 23 reaches a certain amount, the staff can easily turn the dust box 23 to quickly pour out the dust inside, which greatly simplifies the cleaning operation and improves work efficiency.

[0026] Furthermore, to collect dust more efficiently, each perforation 220 is equipped with a dust guide cover 24 on its top. The dust guide cover 24 is installed at the end of the perforation 220 furthest from the drying cylinder, and its shape is adapted to the opening size of the perforation 220, allowing it to tightly cover the top of the perforation 220. Simultaneously, the dust guide cover 24 also has an opening facing the drying cylinder, the orientation of which matches the direction of dust generation when the peeling blade 22 peels the paper. When dust is generated during the peeling process, some dust that might drift away from the drying cylinder is blocked by the dust guide cover 24, while the opening facing the drying cylinder precisely guides the dust into the perforation 220, further reducing dust overflow and improving dust collection efficiency.

[0027] Furthermore, an adjustment device 3 is provided on one of the mounting plates 20. The adjustment device 3 is connected to the connecting rod 21 and is used to drive the connecting rod 21 to rotate, thereby realizing flexible adjustment of the angle of the peeling blade 22 to adapt to the peeling requirements of paper of different thicknesses and materials, and improve the accuracy and stability of the peeling operation.

[0028] Specifically, the adjusting device 3 includes a connecting arm 30, one end of which is sleeved on the connecting rod 21 and fixedly connected to the connecting rod 21, so that the connecting arm 30 can rotate synchronously with the connecting rod 21. The other end of the connecting arm 30 is provided with an elastic adjusting component 31, which is used to drive the connecting arm 30 to swing, thereby driving the connecting rod 21 and the peeling blade 22 to rotate to adjust the angle.

[0029] The elastic adjustment assembly 31 includes a mounting rod 310 and an arc-shaped rod 311. The mounting rod 310 is fixedly connected to one side of the mounting plate 20. The arc-shaped rod 311 passes through the end of the connecting arm 30 away from the connecting rod 21, and the bottom of the arc-shaped rod 311 is fixedly connected to the mounting rod 310. A spring 312 is sleeved on the arc-shaped rod 311. The bottom of the spring 312 abuts against the mounting rod 310, and the top of the spring 312 abuts against the top of the connecting arm 30. A sliding sleeve 313 is also sleeved on the arc-shaped rod 311. The sliding sleeve 313 is located at the top of the connecting arm 30. The sliding sleeve 313 has a screw 314 that passes laterally through the sliding sleeve 313 and is threadedly connected to the sliding sleeve 313 for pressing the arc-shaped rod 311.

[0030] When the angle of the peeling blade 22 needs to be adjusted, the operator can rotate the screw 314 to loosen its clamping force on the arc-shaped rod 311. At this time, the connecting arm 30 can rotate along the arc-shaped trajectory of the arc-shaped rod 311, thereby adjusting the peeling blade 22 to the required angle. After the angle is determined, the screw 314 is rotated in the opposite direction to re-clamp the arc-shaped rod 311, thus fixing the position of the connecting arm 30 and the peeling blade 22 and ensuring that the angle remains stable during subsequent operations. This adjustment structure is easy to operate and can quickly achieve precise adjustment of the peeling blade 22 at multiple angles to adapt to different operational needs.

[0031] Furthermore, the drive device 10 is used to drive the peeling device 2 to slide along the height direction of the support frame 1. The drive device 10 includes support rods 11 and a sliding plate 12. The two support rods 11 are arranged along the height direction of the support frame 1. The sliding plate 12 is slidably mounted on the two support rods 11. Extension rods 121, fixedly connected to the mounting plate 20, are provided on both sides of the sliding plate 12. When the sliding plate 12 moves, it can drive the peeling device 2 to move synchronously, thereby adjusting the height of the peeling device 2.

[0032] In order to ensure the stability of the sliding plate 12 sliding on the support rod 11, the support rod 11 is provided with a slide rail 110 along the height of the support rod 11, and the sliding plate 12 is provided with a slider 120 that slides in cooperation with the slide rail 110.

[0033] By setting up the drive device 10, when the dust box 23 is full of dust and needs to be cleaned, the drive device 10 can drive the peeling device 2 to descend, reducing the height of the dust box 23. This prevents dust from splashing when workers open the dust box 23 to empty the dust due to its excessive height, further ensuring a clean working environment. In addition, the height adjustment function can work in conjunction with the adjustment device 3. By adjusting the angle of the peeling blade 22 and the overall height of the peeling device 2, the peeling blade 22 can more accurately contact drying cylinders of different specifications and paper of different thicknesses and materials, greatly improving the adaptability of the device to various working scenarios.

[0034] Furthermore, the drive device 10 also includes a power assembly 13 for driving the slide plate 12 to slide along the support rod 11. The power assembly 13 includes a drive motor 132 and a crossbeam 130 disposed between the two support rods 11 and parallel to the two support rods 11. The crossbeam 130 is provided with a rack 131, which is arranged along the length direction of the crossbeam 130. The output end of the drive motor 132 is provided with a gear 132 that meshes with the rack 131.

[0035] The power assembly 13 also includes a connecting block 134, which is fixedly connected to the slide plate 12 and the drive motor 132. A rotating bearing 135 is provided on the connecting block 134, and the output end of the drive motor 132 passes through the rotating bearing 135. By providing the rotating bearing 135, when the drive motor 132 is working, its output end will rotate, and the connecting block 134 can be prevented from rotating along with the output end of the drive motor 132 under the action of the rotating bearing 135.
