Description

Technical Field

[0001] The utility model relates to the technical field of auxiliary devices for papermaking equipment, in particular to a paper tube base paper banner moisture adjustment test device. Background Art

[0002] In the papermaking process, the slurry after mixing and dilution is evenly sprayed onto the forming net through the headbox. The slurry moves backward with the forming net, and under the action of the dehydration element, most of the water is gradually removed to form a wet paper web. The wet paper web enters the pressing section for pressing and dehydration after exiting the vacuum roller in the net section, and finally enters the drying section for drying and dehydration. The moisture content of the paper web exiting the vacuum roller is an important factor in ensuring the paper index and the operating conditions of the paper machine.

[0003] If the moisture content of the wet paper web leaving the vacuum roller is too high, it will cause the wet paper web to be crushed in the pressing section, forming embossing or causing paper breaks; if the moisture content of the wet paper web leaving the vacuum roller is too low, it will affect the adjustment of the surface quality and strength properties of the paper web by the pressing section, and will also cause incomplete gelatinization of starch during drying, resulting in reduced papermaking indicators and the production of defective products.

The pressure roller 1 abuts against the vacuum couch roller 7. The wet paper web 8 runs through the pressure roller 1 and the vacuum couch roller 7. The pressure roller 1 is driven by the lifting and adjusting device 3 to apply pressure, so as to achieve precise control of the moisture content of the wet paper web 8. The existence of the sliding device 2 allows the pressure roller 1 to be easily adjusted to adapt to paper webs of different widths. The moisture content of the paper web in this area is adjusted by applying pressure to a partial area of ​​the paper web above the vacuum couch roller 7, and the different effects of the moisture content of the wet paper web 8 out of the vacuum couch roller 7 on the papermaking indicators are quickly verified, and the most suitable moisture content of the vacuum couch roller 7 under the current production conditions is found to ensure paper quality and guide production.

[0027] The sliding device 2 includes a sliding rod seat 21, a plurality of sliding rods 22 and a plurality of fixed sliding blocks 23. The plurality of sliding rods 22 are all installed on the sliding rod seat 21. The plurality of fixed sliding blocks 23 are sleeved on the surface of the sliding rod 22 and can slide along the axial direction of the sliding rod 22. The sliding rod seat 21 is fixedly installed on one side of the supporting device 6. The lifting and lowering adjustment device 3 is movably connected with the corresponding sliding block. The sliding rod 22 is preferably two, and the sliding rod 22 is a smooth metal rod with a diameter of φ40mm. The sliding rod seat 21 is "concave". The two sliding rods 22 are horizontally welded in the groove of the sliding rod seat 21. The two sliding rods 22 are easier to balance and prevent deviation caused by uneven force. The fixed sliding block 23 The preferred number is two. Both fixed sliders 23 are penetrated by two slide bars 22. The slider is composed of a linear bearing with an inner diameter of φ40 mm and a shell. The slider is mounted on the slide bar 22 and can slide along the slide bar 22. The slide bar seat 21 is welded to one side of the slide seat 61. The layout makes the entire device compact and occupies a small area, which is convenient for installation and use at the production site. Both fixed sliders 23 are equipped with a lifting and adjusting device 3 to provide a stable balance for the pressure roller 1. The pressure roller 1 can move freely in the horizontal direction to adapt to paper webs of different widths or adjust the relative position between the pressure roller 1 and the vacuum roller 7, thereby improving the flexibility of adjustment.

[0028] The lifting and lowering adjustment device 3 includes a rotary rod 31, an adjustment block 32, a hand wheel 33, a tightener 34 and an adjuster 35. The hand wheel 33, the adjuster 35, the tightener 34 and the adjustment block 32 are sequentially installed on the rotary rod 31 along the axial direction. The rotary rod 31 is threadedly connected to the fixed slider 23. The end of the adjustment block 32 is detachably installed with a bearing seat 4. The hand wheel 33 is installed at the end of the rotary rod 31 away from the adjustment block 32. The adjuster 35 is located between the hand wheel 33 and the fixed slider 23. The tightener 34 is located between the fixed slider 23 and the adjustment block 32. The adjustment block 32 is bolted to the bearing seat 4. The bearing seat 4 is a P210 bearing seat 4 equipped with a UC210 outer spherical ball bearing. The rotary rod 31 is a stainless steel screw with a diameter of φ50 mm. The adjustment block 32 is welded to the lower end of the rotary rod 31. When the rotary rod 31 is installed to the fixed slider 23, the pad can be screwed in. The pressure roller 1 can be roughly or finely adjusted in height by the adjuster 35 and the adjustment block 32, and pressurized by the hand wheel 33. Different pressurization pressures can be obtained by applying different pressures of the hand wheel 33 to meet the adjustment requirements of the moisture content of the paper web under different process requirements, and can be adjusted at any time. The hand wheel 33, the adjuster 35, the fixed slider 23 and the tightener 34 are all screwed on the rotary rod 31.

The diameter of the pressure roller 1 is φ300mm. The pressure roller 1 of different lengths can be replaced by simply removing the retaining ring 5. The roller surface of the pressure roller 1 is covered with polyurethane with a thickness of 10mm. The retaining ring 5 can not only prevent the roller body from shaking during rotation, but also ensure the stability of the pressure roller 1 during the lifting process, prevent the adjustment effect from being affected by axial displacement, and ensure its smooth rotation when pressure is applied.

[0030] Working principle: The staff installs the device as a whole to the working position, adjusts the height of the pressure roller 1 by adjusting the block 32 and the adjuster 35, and adjusts the pressure position of the pressure roller 1 on the vacuum couch roller 7 by sliding the fixed slider 23 on the slide bar 22. After the adjustment, tighten the tightening device 34 to fix the pressure roller 1 in the working position, and obtain different pressures of the pressure roller 1 by adjusting the tightening degree of the hand wheel 33. After the pressure roller 1 is pressurized, the moisture content of the wet paper web 8 in the pressure area out of the vacuum couch roller 7 is changed.
