Description

Technical Field

[0001] The utility model application relates to the technical field of scrapers, in particular to a pneumatic oscillating scraper. Background Art

[0002] Papermaking requires pulping, deinking, bleaching, forming and papermaking, followed by pressing and dehydration. After dehydration and drying, it is divided into rolls and packaged. During the forming and pressing process, a large amount of sticky dirt is generated, and the dirt often sticks to the roller surface or the paper surface. In order to prevent the dirt from accumulating on the roller surface, it needs to be scraped off with a scraper.

[0003] According to a pneumatic oscillator of a scraper for a papermaking machine with the Chinese publication number CN213867080U, the pneumatic oscillator includes a first moving block and a second pulley, a first screw rod is installed inside the first moving block, and a second pulley is installed at the right end of the first screw rod. The utility model is provided with the first screw rod and the second screw rod both being threadedly connected to the scraper, so that the scraper is firmly fixed on the first screw rod and the second screw rod, thereby avoiding the rotation of the single screw rod to drive the scraper to rotate, and at the same time, the two screw rods can more stably drive the scraper to move on the screw rod; the second motor is energized to drive the third screw rod to rotate, and then the second moving block is driven to move on the third screw rod through the thread, so that the scraper and the paper pressing roller are more closely fitted, thereby better cleaning the paper pressing roller.

[0004] However, the scraper is not easy to adjust its length according to the length of the paper pressing roller, and when scraping, it is not easy to adjust the angle of the scraper according to the angle and thickness of the paper pressing to avoid affecting the normal paper pressing, which greatly reduces the practicality and application range of the scraper.

One end of the adjusting screw rod 3 extends to the outside of the supporting rail 1 and is fixed to the output shaft of the servo motor 2. A movable sleeve block 4 is threadedly sleeved on the adjusting screw rod 3 inside the supporting rail 1. A thread that cooperates with the adjusting screw rod 3 is opened inside the movable sleeve block 4. A rotating hole that cooperates with the fixed screw 6 is opened inside the rotating sleeve 7. The length of the fixed clamping block 8 and the rotating sleeve 7 is The length of the fixed screw 6 is less than that of the movable sleeve 4, and an upper support plate 5 is fixed to one end extending to the outside of the support slide rail 1. The upper support plate 5 is set to an inverted "U" shape, and the top surface of the upper support plate 5 slides in contact with the bottom surface of the support slide rail 1. The width of the top surface of the upper support plate 5 is less than the width of the support slide rail 1. A fixed screw 6 is fixed inside the upper support plate 5, and a rotating sleeve 7 is rotatably sleeved on the fixed screw 6. A fixed clamp 8 is threadedly sleeved on the fixed screw 6 on the side of the rotating sleeve 7, and the scraper body 11 is detachably connected to the bottom of the rotating sleeve 7.

[0022] Specifically, when the angle of the scraper body 11 needs to be adjusted, the fixed clamp 8 is twisted to release the clamping of the rotating sleeve 7 by the fixed clamp 8, and the rotating sleeve 7 can be rotated to adjust the direction of the bottom opening of the scraper body 11, so as to avoid the scraper body 11 affecting the normal paper pressing of the roller. When scraping, the servo motor 2 drives the adjusting screw 3 to rotate, and drives the movable sleeve 4 on the adjusting screw 3 to move, which can drive the scraper body 11 to move for scraping.

[0023] As an optimization solution, Figure 2 and Figure 3 As shown, a lower support plate 9 is fixed to the bottom surface of the rotating sleeve 7, and the lower support plate 9 is set to an inverted "U" shape. The width of the connecting block 10 is equal to the width inside the lower support plate 9, and the scraper body 11 is set to an arc shape with a lower opening that cooperates with the roller. A connecting block 10 is sleeved inside the lower support plate 9, and the connecting block 10 extends to one end below the lower support plate 9 and is fixed on the top surface of the scraper body 11. The connecting block 10 is symmetrically slidably sleeved inside the limit rod 12, and a spring 14 is fixed between the two limit rods 12. Limiting holes 13 that cooperate with the limiting rod 12 are opened on both sides of the lower support plate 9. The two limiting holes 13 are both set to a rectangle that cooperates with the limiting rod 12. Each limiting rod 12 is set to a horizontally placed "T" shape, and the width inside the connecting block 10 is greater than the sum of the widths of the two limiting rods 12.

[0024] Specifically, when the scraper body 11 needs to be disassembled, press the limit rods 12 on both sides so that the limit rod 12 compresses the spring 14 and moves out of the limit hole 13, so that the limit rod 12 can release the limit on the connecting block 10, pull the connecting block 10, and pull the connecting block 10 out from the lower support plate 9 to replace the scraper body 11. During installation, press the limit rod 12 to engage the connecting block 10 into the lower support plate 9, and then release the limit rod 12. At this time, the limit rod 12 is aligned with the limit hole 13 and can be inserted into the limit hole 13 under the push of the spring 14.
