Description

Technical Field

[0001] This utility model mainly relates to the field of paper machine stabilizer technology, specifically a paper stabilizer for a paper machine. Background Technology

[0002] The main function of the paper web stabilizer in a papermaking machine is to improve the smoothness of paper web operation and reduce paper breaks and defects. When used in the paper feeding cylinder and the single-hanging drying cylinder group in the drying section, it can not only improve the smoothness of paper web operation, but also increase the evaporation rate of paper web moisture. It has a fixed structure and strong sealing, but its evaporation efficiency and discharge efficiency are generally average.

[0003] Paper machines can typically produce different types of paper, but the spacing between a pair of guide rollers at the paper web stabilizer outlet and the vertical spacing between the spreader rollers used to spread and guide the paper need to be adjusted according to the paper thickness to achieve the desired tension and spread of paper of different thicknesses. Existing paper web stabilizers usually require adjusting the spacing between the guide rollers and spreader rollers one by one. Since the paper thickness is usually relatively thin, the difference between different paper thicknesses is not significant. When adjusting the spacing between the guide rollers and spreader rollers, the actual amount of displacement adjustment is very small. Adjusting small distances manually one by one is actually quite difficult, and hand tremors can easily lead to errors. The guide rollers and spreader rollers are adjusted separately, and an error in one of them will affect the stability and conveying of the paper. Utility Model Content

[0004] This utility model provides a solution that is significantly different from existing technologies, addressing the problem that existing technologies are too simplistic. It mainly provides a paper stabilizer for paper machines, which solves the technical problem mentioned in the background that existing guide rollers and spreader rollers are adjusted manually one by one, and an error in one of the adjustments will affect the stability and transport of the paper.

[0005] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows:

[0006] A paper stabilizer for a paper machine includes a paper web stabilizer body, a paper outlet on the paper web stabilizer body, a guide roller assembly on the paper outlet for guiding paper output, a support on the paper web stabilizer body, a stretching roller assembly on the support for tensioning and conveying the paper, and an adjustment component on the support for synchronously adjusting the spacing between the guide roller assembly and the stretching roller assembly.

[0007] Preferably, the guide roller assembly includes a first guide roller and a second guide roller, the first guide roller rotor is rotatably connected to the paper outlet, a first moving block is slidably connected to the paper outlet, and the second guide roller rotor is rotatably connected to the first moving block.

[0008] Preferably, the stretching roller assembly includes a first stretching roller and a second stretching roller, the first stretching roller is rotatably connected to a support, a third moving block is slidably connected to the support, and the second stretching roller is rotatably connected to the third moving block.

[0009] Preferably, the adjustment component includes a servo motor, which is fixedly mounted on a bracket. A support rod is provided at the output end of the servo motor, and the support rod is rotatably connected to the bracket. A first connecting plate is fixedly mounted at the end of the support rod away from the servo motor, and a second connecting plate is hinged to one side of the first connecting plate.

[0010] Preferably, a second movable block is slidably connected to the first connecting plate, and one end of the second guide roller is rotatably connected to the second movable block.

[0011] Preferably, a fourth movable block is slidably connected to the second connecting plate, and one end of the second stretching roller is rotatably connected to the fourth movable block.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: by activating the adjustment component, the distance between the guide roller group and the stretching roller can be adjusted simultaneously through the adjustment component, and the distance between the two roller groups can be finely adjusted at the same time. This reduces the possibility of errors caused by adjusting the distance between the guide roller group and the stretching roller separately. Even if errors occur when adjusting the distance simultaneously through the adjustment component, both the guide roller group and the stretching roller will have errors, but the adjustment amount between the guide roller group and the stretching roller is still the same. In this way, the guide roller group and the stretching roller can still continue to work, and the impact on the paper conveying tension error is small.

However, the utility model can be implemented in different forms and is not limited to the embodiments described in the text. On the contrary, these embodiments are provided to make the disclosure of the utility model more thorough and comprehensive.

When an element is referred to as being "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0023] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly associated with those skilled in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments and is not intended to limit the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0024] Please refer to the appendix carefully. Figures 1-5 A paper stabilizer for a paper machine includes a paper web stabilizer body 1, a paper outlet 2 on the paper web stabilizer body 1, a guide roller group on the paper outlet 2 for guiding paper output, a support 3 on the paper web stabilizer body 1, a stretching roller group on the support 3 for tensioning and conveying paper, and an adjustment component on the support 3 for synchronously adjusting the spacing between the guide roller group and the stretching roller group.

[0025] The specific operation process of this utility model is as follows: Start the adjustment component. The adjustment component adjusts the distance between the guide roller group and the stretching roller group at the same time. Since the adjustment is carried out simultaneously by the adjustment component, the adjustment parameters of the guide roller group and the stretching roller group are kept proportional. This ensures that the adjusted guide roller group and the stretching roller group can stably convey and tension paper of the same thickness. After adjusting the guide roller group and the stretching roller group, stop driving the adjustment component. At this time, the paper is output from the paper outlet 2. The paper passes through the guide roller group for conveying and then is stretched and tightened by the stretching roller group for conveying.

[0026] Please refer to Figures 1-5 The guide roller assembly includes a first guide roller 4 and a second guide roller 5. The first guide roller 4 is rotatably connected to the paper outlet 2. A first moving block 11 is slidably connected to the paper outlet 2. The second guide roller 5 is rotatably connected to the first moving block 11. The adjustment assembly includes a servo motor 10. The servo motor 10 is fixedly mounted on the bracket 3. A support rod is provided at the output end of the servo motor 10. The support rod is rotatably connected to the bracket 3. A first connecting plate 8 is fixedly mounted at the end of the support rod away from the servo motor 10. A second connecting plate 9 is hinged to one side of the first connecting plate 8. A second moving block 12 is slidably connected to the first connecting plate 8. One end of the second guide roller 5 is rotatably connected to the second moving block 12.

[0027] The servo motor 10 is started, driving the support rod to rotate. The support rod then drives the first connecting plate 8 to rotate, forming a seesaw-like structure with the support rod as a fulcrum. The first connecting plate 8 drives the second moving block 12 to move. The second moving block 12 is laterally slidably connected to the first connecting plate 8, and it moves along a groove on the first connecting plate 8 to accommodate its movement. A second guide roller 5 is rotatably connected to the second moving block 12, and its rotating rod also rotates to accommodate the movement of the second moving block 12. The first moving block 11 is dynamically connected. When the second moving block 12 pulls the second guide roller 5, the rotating rod of the second guide roller 5 will pull the first moving block 11. The first moving block 11 is longitudinally slidably connected to the paper outlet 2. At this time, the first moving block 11 moves along the longitudinal groove of the paper outlet 2 to adjust the longitudinal position of the second guide roller 5, thereby adjusting the distance between the first guide roller 4 and the second guide roller 5. The first guide roller 4 and the second guide roller 5 can be driven by a motor, and then the first guide roller 4 and the second guide roller 5 can rotate relative to each other to transport paper through the transmission of the tension belt pulley group.

[0028] Please refer to Figures 1-5 The stretching roller assembly includes a first stretching roller 6 and a second stretching roller 7. The first stretching roller 6 is rotatably connected to the support 3. A third moving block 13 is slidably connected to the support 3. The second stretching roller 7 is rotatably connected to the third moving block 13. A fourth moving block 14 is slidably connected to the second connecting plate 9. One end of the second stretching roller 7 is rotatably connected to the fourth moving block 14.

[0029] When the first connecting plate 8 rotates, it will cause the second connecting plate 9 at one end to tilt upwards or downwards. A fourth moving block 14 is longitudinally slidably connected to the second connecting plate 9. The fourth moving block 14 moves along the longitudinal groove on the second connecting plate 9 to allow the second connecting plate 9 to move. The rotating rod of the second stretching roller 7 is rotatably connected to the fourth moving block 14. When the fourth moving block 14 moves, the second stretching roller 7 will rotate to adapt to the movement of the fourth moving block 14. The third moving block 13 is laterally slidably connected to the bracket 3. When the second stretching roller 7 moves, it pulls the third moving block 13 along the lateral direction of the bracket 3. The chute moves to adjust the vertical and horizontal spacing between the second stretching roller 7 and the first stretching roller 6. The second stretching roller 7 and the first stretching roller 6 are also driven by a motor and a tension pulley assembly to rotate relative to each other to transport the paper. The spacing between the first stretching roller 6 and the second stretching roller 7 is relatively large, and the paper needs to pass through the first stretching roller 6 and the second stretching roller 7 from top to bottom (the paper passes through the horizontal gap between the first stretching roller 6 and the second stretching roller 7). The angle at which the paper wraps around the two stretching rollers is greater than 120°, so that the two stretching rollers can unfold and tighten the paper for transport.

[0030] The connection points of the second moving block 12 and the second guide roller 5, and the connection points of the fourth moving block 14 and the second stretching roller 7, are symmetrical in the horizontal or vertical position on their respective connecting plates. This ensures that the displacement of the second guide roller 5 and the second stretching roller 7 is the same when they are adjusted (assuming that the sliding distance of the second moving block 12 on the first connecting plate 8 is x, the sliding distance of the fourth moving block 14 on the second connecting plate 9 is also x, so as to ensure that the adjustment amount of the roller spacing is the same for both).

[0031] The present invention has been described above by way of example in conjunction with the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvement made by adopting the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution of the present invention to other occasions without modification, shall be within the protection scope of the present invention.
