Description

Technical Field

[0001] This utility model relates to the field of papermaking technology, specifically to a dewatering structure for the wire pressing section of a paper machine. Background Technology

[0002] Paper is one of the most commonly used items in our daily lives. Whether reading, writing, or drawing, we all come into contact with paper. Paper is also indispensable in industrial, agricultural, and defense production, and the pulp needs to be dehydrated during the papermaking process. In existing technologies, some wire dewatering structures employ an integrated mechanical tumbling and vibration design to improve dewatering efficiency and prevent water reabsorption.

[0003] A search revealed that Chinese patent CN219450266U discloses a dewatering structure for a paper machine wire section. When the motor is turned on, it controls the rotation of a shaft via bevel gears. Gears at both ends of the shaft control the sliding of a rack and pressure plate. As the gears continue to rotate, the meshing between the gears and rack can be disengaged. A support plate and elastic element control the connecting parts to drive the dewatering wire in reciprocating motion and vibrate it, preventing water droplets on the dewatering wire from flowing back into the paper. However, it still has the following technical problems:

[0004] The wet paper web has extremely low strength in the early stages of forming, and its fiber network structure is fragile. The entire dewatering wire section requires frequent tumbling and vibration, which severely disrupts the tension of the paper web during operation. This forced, periodic mechanical impact easily damages the initially formed fiber bonds within the paper web, leading to loose inter-fiber connections and ultimately paper breaks. To address this, we propose a dewatering structure for the paper machine's wire pressing section. Utility Model Content

[0012] In a preferred embodiment of this utility model, the spring is sleeved in the middle of the adjusting rod, and the bottom end of the spring is fixed to the bottom of the inner cavity of the mounting groove.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] (1) Avoid paper breakage in wet paper web and ensure production continuity: This structure abandons the forced vibration design and adopts a stable pressing method of "pressure roller + support roller". The dewatering net and sponge roller are driven in the same direction and at the same speed to absorb the residual moisture of the dewatering net. The wet paper web is kept stable throughout the process without periodic mechanical impact, which effectively protects the fiber network structure of the wet paper web and fundamentally avoids paper breakage problems, ensuring the continuity of paper production.

[0015] (2) Adjustable pressure roller height to adapt to multiple paper web specifications: Through the linkage adjustment mechanism of "knob-positive and negative lead screw-slider-adjusting rod", the pressure roller height can be precisely adjusted according to the requirements of wet paper web of different thicknesses, so as to realize the adaptability adjustment of pressing force - to avoid insufficient dehydration due to insufficient pressing force, and to prevent damage to the paper web structure due to excessive pressing force, significantly improving the equipment's adaptability to different types of paper (such as thin paper, cultural paper, etc.) and enhancing the equipment's versatility.

[0016] (3) Dual dehydration and humidity control to improve dehydration quality and efficiency: This structure constructs a dual humidity control system of "squeeze dehydration + sponge water absorption": In the first stage, the wet paper web is rapidly dehydrated through the pressing action of the pressure roller and the support roller; in the second stage, the sponge roller absorbs the residual moisture in the dehydration net to prevent moisture reabsorption, and the sponge roller achieves moisture regeneration through the squeeze plate, which can continuously maintain a high-efficiency water absorption capacity. At the same time, the negative pressure dehumidification design of the turbine vacuum pump can quickly remove steam and moisture inside the machine body, avoiding the interference of moisture on the dehydration process.

[0017] (4) Reduce component wear and extend equipment service life: The sponge roller and the dewatering net rotate in the same direction and at the same speed through the transmission belt. When they come into contact, they are in "synchronous rolling friction". Compared with the "relative sliding friction" in the traditional structure, the surface wear of the sponge roller and the dewatering net is greatly reduced, the service life of the equipment is increased, and the maintenance cost of the equipment is reduced.

[0026] Example

[0027] Please see Figure 1-5This utility model provides the following technical solution: a dewatering structure for the wire pressing section of a paper machine, comprising: a machine body 1, with a first rotating shaft 2 rotatably connected to both ends of the inner side of the machine body 1 via bearings, a conveyor roller 3 fixed to the shaft of the first rotating shaft 2, a dewatering screen 4 provided on the shaft of the conveyor roller 3, a motor 5 connected to the front end of the left side of the first rotating shaft 2 extending to the outer side of the machine body 1, a first pulley 6 fixed to the front end of the first rotating shaft 2, a transmission belt 7 provided on the first pulley 6, a second pulley 8 provided on the inner right side of the transmission belt 7, a second rotating shaft 9 fixed at the center hole of the second pulley 8, the second rotating shaft 9 extending into the interior of the machine body 1 and rotatably connected to the side wall of the machine body 1 via bearings, a sponge roller 10 fixed to the shaft of the second rotating shaft 9, and adjustment notches 12 opened at the top of the front and rear side frames of the machine body 1, with fixing blocks 13 fixed inside the adjustment notches 12, and the two sets of fixing blocks 13 facing each other. A connecting cylinder 14 is fixed, and a positive and negative screw 15 passes through the middle of the fixing block 13 and the connecting cylinder 14. One end of the positive and negative screw 15 extends to the outside of the fixing block 13 and is fixed with a knob 24. A cavity 16 is opened inside the fixing block 13. A slider 17 is slidably connected inside the cavity 16. An adjusting rod 18 is abutted at the bottom of the slider 17. An installation groove 19 is opened below the cavity 16. The adjusting rod 18 passes through the installation groove 19. A limit block 20 is fixed to the rod body of the adjusting rod 18. A spring 21 is fixed to the bottom end of the limit block 20. A support shaft 22 is fixed to the bottom end of the adjusting rod 18 by bolts. A pressure roller 23 is rotatably connected to the shaft body of the support shaft 22. A support roller 30 is tightly attached to the bottom surface of the upper dewatering net 4. A guide plate 25 is fixed to the lower part of the inner wall of the machine body 1. A water outlet 26 is connected to the bottom end of the guide plate 25. The end of the water outlet 26 extends to the outside of the machine body 1.

[0028] In order to quickly extract the steam and residual moisture inside the machine body 1, reduce the humidity inside the machine body 1, further improve the dewatering efficiency and drying speed of the wet paper web, and avoid the moisture from interfering with the dewatering process, in this embodiment, as a preferred technical solution of the present invention, a connecting pipe 27 is connected to the bottom right side of the guide plate 25, and the end of the connecting pipe 27 extends to the outside of the machine body 1 and is connected to a turbine vacuum pump 28.

[0029] In order to squeeze the sponge roller 10 during the rotation process, squeeze out the water it absorbs, and let the water flow along the inclined extrusion plate 11 to the guide plate 25, so as to realize the release and regeneration of water from the sponge roller 10, ensure that the sponge roller 10 maintains a high water absorption capacity, and avoid water absorption failure due to saturation of the sponge roller 10, in this embodiment, as a preferred technical solution of the present invention, one side of the sponge roller 10 abuts against the extrusion plate 11, and the extrusion plate 11 is inclinedly fixed on the front and rear inner walls of the machine body 1.

[0030] In order to form a stable pressing zone corresponding to the pressure roller 23, the third rotating shaft 29 is rotatably connected to the machine body 1 to achieve flexible rotation, providing stable support for the dewatering net 4, ensuring that the pressing force of the pressure roller 23 on the wet paper web is evenly transmitted, avoiding uneven pressing due to insufficient support, and improving the squeezing and dewatering effect. In this embodiment, as a preferred technical solution of the present invention, the position of the support roller 30 is arranged vertically corresponding to the pressure roller 23, and the third rotating shaft 29 is fixed at the center hole of the support roller 30. The two ends of the third rotating shaft 29 are rotatably connected to the inner wall of the machine body 1 through bearings.

[0031] In order to enable the two sets of sliders 17 to slide synchronously in opposite directions along the cavity 16 through the engagement of the external threads with opposite directions at both ends of the positive and negative lead screws 15 when rotating, so as to provide a power basis for the vertical displacement of the subsequent adjustment rod 18, and realize the precise adjustment of the height of the pressure roller 23 to adapt to the pressing requirements of wet paper webs of different thicknesses, in this embodiment, as a preferred technical solution of the present invention, the sections of the positive and negative lead screws 15 located in the cavity 16 are respectively provided with external threads with opposite directions, and the positive and negative lead screws 15 are threadedly connected to the sliders 17.

[0032] In order to convert the horizontal sliding of the slider 17 into the vertical displacement of the adjusting rod 18, the wedge structure and the inclined surface are mutually engaged and slid together to ensure the stability and accuracy of power transmission, thereby achieving a smooth adjustment of the height of the support shaft 22 and the pressure roller 23 and avoiding jamming or deviation during the adjustment process. In this embodiment, as a preferred technical solution of the present invention, the bottom end of the slider 17 is a wedge structure, the top end of the adjusting rod 18 is correspondingly set as an inclined surface, and the contact surfaces of the slider 17 and the adjusting rod 18 are mutually engaged and can slide relative to each other.

[0033] In order to limit the radial displacement of the adjusting rod 18 during vertical movement and ensure that the adjusting rod 18 always slides stably along the axial direction of the mounting groove 19, and to avoid the position deviation of the pressure roller 23 due to the displacement of the adjusting rod 18, so as to ensure the stability and accuracy of pressing and dewatering, in this embodiment, as a preferred technical solution of the present invention, the outer diameter of the limiting block 20 matches the inner diameter of the mounting groove 19, and the limiting block 20 is slidably connected to the mounting groove 19.

[0034] In order to ensure that the top end of the adjusting rod 18 is always in close contact with the bottom end of the slider 17 through the elastic support of the spring 21, and to prevent the adjusting rod 18 from falling off or loosening due to its own weight, and at the same time to provide a buffer for the adjusting rod 18 during the adjustment process, so as to ensure the reliability and service life of the adjusting mechanism, in this embodiment, as a preferred technical solution of the present invention, the spring 21 is sleeved in the middle of the adjusting rod 18, and the bottom end of the spring 21 is fixed to the bottom of the inner cavity of the mounting groove 19.

[0035] In this embodiment, the turbine vacuum pump is a known technology that is widely used in daily life and utilizes a high-speed rotating impeller to exchange energy with gas molecules. Specifically, a motor drives the impeller to rotate at high speed. After the gas is drawn in, it gains extremely high speed and kinetic energy under the push of the impeller blades. Subsequently, the gas velocity decreases in the diffuser channel, and according to the law of conservation of energy, its kinetic energy is converted into pressure energy, thereby increasing the gas pressure and finally expelling it from the pump body. This continuous process continuously creates a vacuum state at the suction end.

[0036] In summary, with the help of the above-described technical solution of this utility model,

[0037] Working principle: Before starting the equipment, the pressing height of the pressure roller 23 is precisely fine-tuned according to the target thickness of the wet paper web to be processed. The operator turns the knob 24, which drives the positive and negative lead screws 15 that pass through the fixed block 13 and the connecting cylinder 14 to rotate. Because the two ends of the positive and negative lead screws 15 located in the cavity 16 have external threads with opposite directions of rotation, and are threadedly engaged with the sliders 17 that are slidably connected in the cavity 16, the rotation of the lead screws will drive the two sets of sliders 17 to slide in opposite directions along the cavity 16. The bottom end of the slider 17 has a wedge-shaped structure, which fits with the inclined surface at the top of the adjusting rod 18 and can slide relative to it. The horizontal movement of the slider 17 is converted into the vertical displacement of the adjusting rod 18, which in turn drives the bottom end of the adjusting rod 18 to move up and down synchronously through the support shaft 22 fixed by bolts, ultimately achieving precise adjustment of the height of the pressure roller 23. During this process, the limiting block 20 fixed to the body of the adjusting rod 18 fits and slides with the inner diameter of the mounting groove 19, which can limit the radial displacement of the adjusting rod 18 and ensure its vertical movement stability; at the same time, through the elastic support of the spring 21, the top end of the adjusting rod 18 is always tightly attached to the bottom end of the slider 17, preventing the adjusting rod 18 from falling off due to gravity and ensuring the reliability of the adjusting mechanism.

[0038] After adjustment, the wet paper web is laid on the surface of the dewatering screen 4, and the motor 5 is started. The motor 5 drives the first rotating shaft 2 on the left to rotate, and the conveyor roller 3 fixed on the shaft of the first rotating shaft 2 rotates synchronously, driving the dewatering screen 4 to stably convey the wet paper web along the inside of the machine body 1. When the wet paper web runs with the dewatering screen 4 to the bottom of the pressure roller 23, the pressure roller 23 and the corresponding support roller 30 below form a pressing zone. The support roller 30 is rotatably connected to the inner wall of the machine body 1 through the third rotating shaft 29, providing stable support for the dewatering screen 4, so that the pressing force of the pressure roller 23 on the wet paper web is evenly transmitted, realizing the initial squeezing and dewatering of the wet paper web. The squeezed water penetrates to the bottom of the dewatering screen 4. At the same time, when the first rotating shaft 2 rotates, the first pulley 6 fixed at its front end rotates synchronously. Through the power transmission of the transmission belt 7, the second pulley 8 on the right side rotates synchronously with the first pulley 6. The second rotating shaft 9 fixed in the center hole of the second pulley 8 rotates with the pulley, thereby driving the sponge roller 10 fixed on the shaft of the second rotating shaft 9 to rotate. The sponge roller 10 is in close contact with the surface of the dewatering screen 4, and due to the synchronous transmission of the drive belt 7, the sponge roller 10 and the dewatering screen 4 rotate in the same direction and at the same speed. This allows for efficient absorption of residual moisture on the surface of the dewatering screen 4, preventing water droplets on the dewatering screen 4 from being reabsorbed into the wet paper web and ensuring the dewatering quality of the wet paper web. When the sponge roller 10 rotates to the area in contact with the extrusion plate 11, the extrusion plate 11, which is inclined and fixed to the inner walls of the front and rear of the machine body 1, exerts extrusion force on the sponge roller 10, squeezing out the water absorbed by the sponge roller 10. The squeezed-out water flows along the inclined surface of the extrusion plate 11 to the guide plate 25 fixed below the inner wall of the machine body 1, realizing the release and regeneration of water from the sponge roller 10 and ensuring that it continues to maintain efficient water absorption capacity.

[0039] The squeezed water collected by the guide plate 25 converges downwards along the plate surface and is finally discharged outside the machine body 1 through the water outlet 26 connected to the bottom end of the guide plate 25, completing the collection and discharge of liquid water. Simultaneously, steam is generated during the dewatering process of the wet paper web, and moisture easily remains inside the machine body 1. Through the connecting pipe 27 connected to the bottom right side of the guide plate 25, the turbine vacuum pump 28 on the outside of the machine body 1 is started. Utilizing the negative pressure suction of the vacuum pump, the steam and residual moisture inside the machine body 1 are quickly extracted through the connecting pipe 27, reducing the internal humidity of the machine body 1 and further improving the dewatering efficiency and drying speed of the wet paper web. The motor model mentioned above is 61K120RGN-CF. This motor model is for reference only and should meet the operational requirements.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal connection of two components or the interaction between two components.

[0041] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model.
