Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is further described in detail with reference to the following embodiments. The specific embodiments described herein are merely illustrative of the invention and are not intended to be limiting of the invention.
Examples
The utility model discloses a paper web stabilizer, as shown in figure 1, after the paper web 9 is worn out between two compression rollers 1 of press section, hug closely with drying cylinder 2, get into the drying section. In order to enable a good fit of the paper to the drying cylinder 2, the present embodiment provides a web stabilizer below the drying cylinder 2, which can blow air upwards. The specific structure is as shown in figure 1, and comprises an air chamber 4 fixedly connected to the top end of an adjustable support frame 3, wherein the air chamber 4 is integrally rectangular, the length of the air chamber is slightly longer than the width of paper web, the air chamber is transversely arranged below the paper and is vertical to the moving direction of the paper, and a vent hole 42 connected with an air source is formed in the side wall of one side of the air chamber 4. The air chamber 4 is provided with a strip-shaped air nozzle 41 along the length direction thereof at one side close to the paper, namely, the top of the air chamber 4, the air nozzle 41 is arranged obliquely upwards, and the direction of the air nozzle 41 is consistent with the moving direction of the paper and faces to the tangential direction of the drying cylinder 2.
Referring to fig. 1, in order to prolong the contact time and the contact area of the air current and the paper, the utility model discloses at the top of air chamber 4 still fixedly connected with arc guide plate 5, this guide plate 5 one end and air chamber 4 outer wall fixed connection, the other end is the outside tangent line direction of the directional dryer 2 of crooked arc. In order to enable the guide plate 5 to be used in cooperation with drying cylinders 2 with different diameters, the guide plate 5 in the embodiment is in a soft sheet shape, such as an ordinary iron sheet or an aluminum sheet, and considering that the paper has water vapor, in order to avoid substances such as rust generated by long-term use of the guide plate 5, a stainless steel metal sheet is preferably selected, so that the guide plate has a shaping effect and also has certain softness. A positioning plate 6 is fixedly arranged on the outer wall of the air chamber 4 in an extending mode, a compression bolt 7 is connected between the positioning plate 6 and the guide plate 5, one end of the compression bolt 7 is connected with the outer wall of the guide plate 5 in a positioning and rotating mode, and the other end of the compression bolt is in threaded connection with the positioning plate 6. Screwing the compression bolt 7 can adjust the distance between the guide plate 5 and the positioning plate 6, thereby changing the fit degree between the guide plate 5 and the drying cylinder 2, being applicable to drying cylinders 2 with different diameters, and because the compression bolt 7 is rotationally connected with the outer wall of the guide plate 5 in a positioning way, the compression bolt 7 can rotate relative to the guide plate 5, but can not drive the guide plate 5 to rotate. The number of the compression bolts 7 can be increased properly according to the width of the guide plate 5.
Referring to fig. 1, at the free end tip of guide plate 5, the thickness threaded connection who runs through guide plate 5 has positioning bolt 8, and the tip of the both sides of guide plate 5 threaded connection has a positioning bolt 8 respectively, and this positioning bolt 8 stretches out guide plate 5 and the directional one end activity butt of 2 driers on the outer wall at 2 both ends of driers to avoid the direct and 2 periphery butts of 2 driers of guide plate 5 tip, influence the transportation of paper. And, the distance that the positioning bolt 8 stretches out of guide plate 5 is adjusted, can adjust the thickness of the gap between guide plate 5 and the dryer 2 outer wall to the paper that adapts to different thickness passes.
Referring to fig. 1 and 2, the adjustable supporting frame 3 includes an upper sleeve 31 and a lower support tube 32, the lower support tube 32 is slidably nested in the upper sleeve 31, a plug pin 33 is inserted into the upper sleeve 31, and a plurality of insertion holes 34 matched with the plug pin 33 are formed in the lower support tube 32 along the length direction thereof. The bolt 33 is inserted into the insertion holes 34 at different positions, so that the whole height of the adjustable support frame 3 can be changed, the vertical distance between the air chamber 4 and the paper web 9 can be adjusted, the minimum air flow is ensured, and the maximum working efficiency is generated; meanwhile, the paper is protected from being broken due to overlarge airflow.
The working principle is as follows: the height of the adjustable support frame 3 is first adjusted so that the air outlet 41 of the air chamber 4 is kept at a small vertical distance, about 2cm, from the web 9. And then adjusting a compression bolt 7 and a positioning bolt 8 to enable the guide plate 5 to surround the periphery of the drying cylinder 2, wherein the size of a gap between the free end of the guide plate 5 and the outer wall of the drying cylinder 2 is about 2-3 times of the thickness of paper. The in-process that the paper removed from compression roller 1 to dryer 2, the air supply is to air chamber 4 in conveying gas, the gas in the air chamber 4 outwards spouts from jet port 41, blows the bottom surface of beating at the paper, makes paper and dryer 2 closely laminate, and under the direction of guide plate 5, the air current removes along with the paper, can play the effect of carrying to the paper, and the area of contact of gas and paper is great simultaneously, and contact time is also longer, and the pressure of air current is softer, can not cause harmful effects to the paper.
The above description is only exemplary of the present invention and should not be taken as limiting the scope of the present invention, as any modifications, equivalents, improvements and the like made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
