Description

Technical Field

[0001] The invention relates to the technical field of papermaking machines, in particular to a papermaking machine with an adjustable paper winding roller structure. Background Art

[0002] The papermaking machine is the core equipment for continuous production of paper, and the reel is a key component of the papermaking machine's finishing section, responsible for winding the dried paper web into a cylindrical reel. Different paper sheets have different reel inner diameters, so reels with different outer diameters are required.

[0003] The outer diameter of the existing paper reel is almost always a fixed value. Therefore, when it is necessary to replace it for different paper industries, the original paper reel needs to be disassembled and then reinstalled with a new one. The disassembly and assembly operation is cumbersome, the paper reel is long, and the cooperation of multiple people is required. The disassembly and assembly process is slow, resulting in increased labor costs and longer time for replacing the paper reel.

[0004] Some paper rollers use a variable diameter structure or a stepless variable diameter structure. For example, the Chinese utility model patent with announcement number CN206624515U provides a stepless variable diameter roller. This patent can adjust the outer diameter of the paper roller without manual intervention and is simple to operate. However, the current variable diameter structures almost all use a retractable roller shaft to adjust the maximum radius of the roller. This causes this type of roller to change the inner cross-section of the paper winding from a circle to a polygon when winding paper. The number of sides of the polygon is affected by the number of rollers that are circumferentially retractable, and is mostly hexagonal and octagonal. In addition, it is necessary to consider the spatial interference when the roller is contracted to the minimum radius, resulting in the number of rollers used to adjust the radius not being able to be set unlimitedly. As a result, it is difficult to solve the problem of the inner cross-section becoming a polygon with this type of variable diameter structure. This does not meet the demand for a circular inner cross-section in existing paper production. Therefore, this patent cannot be used in paper manufacturing that requires a certain inner cross-section of the paper winding. Summary of the Invention

DETAILED DESCRIPTION

[0035] The technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0036] See also Figures 1-8 A papermaking machine with an adjustable paper winding roller structure includes a papermaking machine body 1, on which a paper winding device 2, a drying cylinder 101, a felt cloth corrector 102, a felt cloth guide roller 103 and a felt cloth tensioner 104 are respectively provided, and a drying cylinder hood 105 is provided outside the drying cylinder 101.

[0037] The paper reel 2 is equipped with an inner roller 3, which is provided with guide grooves 4 and sliding grooves 5 spaced along its outer periphery. These guide grooves 4 and sliding grooves 5 are arranged in two mirror-image groups along the axis of the inner roller 3. A plurality of outer roller blocks 6 are provided at each end of the inner roller 3. These outer roller blocks 6 include an inner circular portion 61 and an outer circular portion 62. Inner and outer circular connecting portions 63 are integrally formed at the four corners between the inner and outer circular portions 61 and 62. The guide grooves 4 allow the inner and outer circular connecting portions 63 to pass through and guide them.

[0038] Through several outer winding roller blocks 6, the paper winding device 2 can be flexibly adjusted between two outer diameters; by making the outer winding roller blocks 6 in a spaced-apart state, the paper can be supported and restricted, and the inner cross-section of the paper when it is wound can be ensured to be circular, meeting the requirements of the paper winding device for the inner cross-section.

[0039] The outer and inner portions 62 and 61 are located on the outer and inner sides of the inner roller 3, respectively. Four independently provided inner and outer connecting portions 63 allow them to slide into the inner roller 3 from one end during installation. Because the guide grooves 4 and sliding grooves 5 do not completely penetrate the axis of the inner roller 3, a partition appears between the two mirror-image sets of guide grooves 4 and sliding grooves 5 in the middle of the inner roller 3. This prevents the inner roller 3 from disintegrating naturally when both ends are open.

[0040] The outer ends of the inner roller 3 are secured with stopper sleeves 7 via flanges, with baffles 8 fixed within the stopper sleeves 7. Specifically, after the necessary components of the inner roller 3 are installed, the flanges are welded to the ends of the inner roller 3, and the stopper sleeves 7 are secured via the flanges. The stopper sleeves 7 can either seal one end of the inner roller 3 or connect to an external component.

[0041] The inner roller 3 is also provided with a movable assembly, which includes a screw 9 rotatably connected between two baffles 8. A motor 10 is fixed to one side of one baffle 8, and the output end of the motor 10 is fixedly connected to one end of the screw 9. A connecting sleeve 11 is coaxially fixed to each of the two inner circular portions 61 at the innermost ends, and the connecting sleeve 11 is threadedly connected to the outer side of the screw 9. Two symmetrical inner and outer circular connecting portions 63 on the outer roller block 6 are provided with wire grooves 12 on either side. A wire roller 13 is rotatably connected in the wire grooves 12, and a pull wire 14 is fixed to the wire roller 13. The pull wire 14 is wound around the wire roller 13. A torsion spring 15 is sleeved on the outer side of one end of the wire roller 13. The two ends of the torsion spring 15 are respectively fixed to the adjacent wire roller 13 and the adjacent side of the wire groove 12. One end of the adjacent pull wires 14 in the two adjacent outer roller blocks 6 is fixedly connected to each other, and one end of the pull wire 14 located on the outer end face of the outer roller block 6 is fixedly connected to the end face of the adjacent inner roller 3. The baffle 8 is convenient for installing the motor 10 , and is also convenient for opening a hole and supporting both ends of the screw rod 9 .

[0042] It should be noted that the connecting sleeve 11 is used to connect to the screw 9. The inner diameter of the inner portion 61 is larger than that of the screw 9, ensuring that the remaining outer roller blocks 6 not equipped with the connecting sleeve 11 do not interfere with the screw 9 during movement. When the motor 10 drives the screw 9 to rotate, the connecting sleeve 11, through the threaded engagement with the screw 9, drives the adjacent outer roller blocks 6 to move. The wire groove 12 is used to install and store the wire roller 13, preventing it from protruding from one side of the outer roller block 6. The pull wire 14 can be made of steel wire rope to ensure durability and longevity.

[0043] The pull wire 14 is wound around the wire roller 13. Through the rotation of the wire roller 13, when the two outer roller blocks 6 are in contact, the pull wire 14 can be hidden, preventing the pull wire 14 from flying around without force and being squeezed and worn between the structures, thereby reducing the service life. When the outer roller block 6 equipped with the connecting sleeve 11 moves in a direction away from the adjacent outer roller block 6, the pull wire 14 on the outer roller block 6 equipped with the connecting sleeve 11 can pull the wire roller 13 on the adjacent outer roller block 6 to rotate and release the adjacent pull wire 14 until the pull wire 14 is naturally tightened. At this time, the adjacent outer roller block 6 will continue to drive the next outer roller block 6 to move through the rear pull wire 14.

[0044] When the outer roller block 6 with the connecting sleeve 11 installed moves toward the adjacent outer roller block 6, the tension wire 14 will be in a relaxed state without any force and cannot be rewound onto the line roller 13. Therefore, a torsion spring 15 is provided outside the line roller 13. When the outer roller block 6 with the connecting sleeve 11 installed moves away from the adjacent outer roller block 6, the adjacent line roller 13 rotates, and the torsion spring 15 will deform accordingly, increasing its own elastic force and storing elastic force. When the outer roller block 6 with the connecting sleeve 11 installed moves toward the adjacent outer roller block 6, since the tension wire 14 and the line roller 13 are no longer affected by external forces, the torsion spring 15 releases its own elastic force and drives the line roller 13 to rotate in the opposite direction, causing the relaxed tension wire 14 to be tightened again and rewound onto the adjacent line roller 13 as the outer roller block 6 moves.

[0045] The paper winding roller structure can be variably adjusted between two outer diameters through the moving component; when adapting to the outer diameter of the inner winding roller 3, several outer winding roller blocks 6 at both ends of the inner winding roller 3 are not axially opened, which can limit the edge of the paper during the paper winding process; and when adapting to the outer diameter of the outer winding roller block 6, several outer winding roller blocks 6 will move and open at equal intervals to support the paper. The outer wall of the outer winding roller block 6 is a circular arc surface and is used to wind the paper. The whole process can be automatically controlled without human assistance, which can meet the requirements of circular cross-sections in paper production.

[0046] In this embodiment, the support assembly includes a receiving groove 64 opened at both ends of the outer circular portion 62. There are four receiving grooves 64 on the end face of the outer circular portion 62. The receiving grooves 64 and the inner and outer circular connecting portions 63 are staggered in the circumferential direction of the outer winding roller block 6. A support rod 16 is rotatably connected in the receiving groove 64. The adjacent sides of the inner circular portion 61 and the outer circular portion 62 are respectively integrally formed with a protrusion 17. An angle control rod 18 is rotatably arranged between the two adjacent protrusions 17. A control block 19 is externally threaded on the angle control rod 18. Both sides of the control block 19 are rotatably connected with a connecting rod 20. One end of the connecting rod 20 is rotatably connected to the adjacent support rod 16. A gear 21 is fixed to the bottom end of the angle control rod 18. Racks 22 meshing with corresponding gears 21 are also circumferentially distributed in the inner winding roller 3. Fixed rods 23 are respectively fixed at both ends of the rack 22. One end of the fixed rod 23 is fixedly connected to the inner surface of the inner winding roller 3.

[0047] When the outer rolling roller block 6 moves, the connecting rod 20, the control block 19 and the angle control rod 18 on the outer rolling roller block 6 can extend from the sliding groove 5 to avoid conflict and interference and ensure the normal movement of the entire structure.

[0048] It should be noted that the storage groove 64 is used to hide the support rod 16 when it does not need to be stretched out, which can avoid the surfaces of the outer roll roller blocks 6 from protruding from each other, so that the gap between the two outer roll roller blocks 6 when they are fitted together increases, resulting in a reduction in the available paper winding range on the inner roll roller 3. At the same time, it avoids the problem of lengthening the inner roll roller 3 to ensure that the paper winding range of the inner roll roller 3 remains unchanged, which leads to an increase in material costs.

[0049] The support rod 16 is rotatably mounted in the receiving groove 64 via a movable rod; the protrusion 17 forms a mounting surface for drilling and mounting the angle control rod 18. The angle control rod 18 is provided with threads and is threadedly connected to a control block 19. Connecting rods 20 are rotatably connected to both sides of the control block 19. One end of the connecting rod 20 is rotatably connected to the adjacent support rod 16 via a pin. When the angle control rod 18 rotates, since the connecting rod 20 is simultaneously connected to the support rod 16 and the control block 19, the support rod 16 cannot rotate with the angle control rod 18, and thus the control block 19 cannot rotate either. This allows the control block 19 to move along the length of the angle control rod 18 under the action of the threads; and when the control block 19 moves, the connecting rod 20 can push the angle control rod 18 to rotate around the center along a fixed trajectory until the outer arc surface of the support rod 16 completely overlaps with the outer arc surface of the adjacent outer roll roller block 6.

[0050] In addition, the rotation angle of the angle control rod 18 needs to be controlled. Therefore, before manufacturing, the tooth spacing of the rack 22 needs to be designed. Among the multiple outer roller blocks 6 at the same end, the outer roller block 6 closest to the longitudinal center of the inner roller 3 has the largest movement distance, while the outer roller block 6 relatively farthest has the smallest movement distance. The rack 22 is provided with a fixed-length tooth profile, so that when adjacent outer roller blocks 6 completely pass over the rack 22, the adjacent gears 21 can rotate a fixed angle; at the same time, when resetting, they can also rotate in the opposite direction to the same fixed angle. By changing the pitch of the angle control rod 18, the angle control rod 18 can be controlled to rotate to different angles and the control block 19 can be raised and lowered to a fixed height. It is also possible to adjust the initial position of the control block 19 on the angle control rod 18 and the length of the connecting rod 20.

[0051] When the support rod 16 is completely hidden in the storage groove 64, the control block 19 is in a fixed position on the angle control rod 18. Under the premise that the support rod 16 needs to rotate to a fixed angle, the longer the length of the connecting rod 20, the smaller the height that the control block 19 needs to rise. Therefore, under the premise that the pitch of the angle control rod 18 remains unchanged, the angle that the angle control rod 18 needs to rotate to is the minimum. Through the above design, the outer roller blocks 6 can be designed as a whole and individually according to the length of the inner roller 3, the number of outer roller blocks 6 required, and the spacing between adjacent outer roller blocks 6 during product manufacturing. This ensures that when all outer roller blocks 6 are separated from each other, the support rods 16 on adjacent outer roller blocks 6 can be rotated to a fixed position.

[0052] When the outer winding roller block 6 moves, the four adjacent gears 21 will mesh with the adjacent racks 22 and drive the angle control rod 18 to rotate. The angle control rod 18 drives the control block 19 to rise and fall through the threaded connection between the control block 19, and then the connecting rod 20 pulls the support rod 16 to rotate around its own rotation center, so as to facilitate the opening and retraction of the support rod 16.

[0053] The support assembly fills the gap between adjacent outer roller segments 6 and provides support when the inner cross-section of the paper roll fits within the outer diameter of the outer roller segment 6. This prevents concavity in some areas of the paper roll, thereby preventing paper collapse during the winding process. Furthermore, the support rods 16 expand and contract in tandem with the extension and retraction of the outer roller segment 6, eliminating the need for additional control and reducing the requirements for the control system.

[0054] In this embodiment, a clearance groove 24 is also provided within the receiving groove 64 to prevent interference between the connecting rod 20 and the receiving groove 64 during rotation. To ensure that one side of the receiving groove 64 fits snugly against the support rod 16 when retracted, the receiving groove 64 is provided with a relatively small depth. Therefore, to accommodate the installation position of the support rod 16, the clearance groove 24 is provided within the receiving groove 64 to prevent interference between the connecting rod 20 and the receiving groove 64 during rotation.

[0055] In this embodiment, four positioning rods 25 are evenly distributed along the circumference of the outer side of the connecting sleeve 11. The positioning rods 25 cooperate with the guide grooves 4 and position the maximum moving distance of the two outer winding roller blocks 6 equipped with the positioning rods 25.

[0056] In this embodiment, a wire hole 26 is opened on the wire roller 13, and one end of the pull wire 14 passes through the adjacent wire hole 26. The wire hole 26 facilitates the pull wire 14 to pass through and be knotted, so that the pull wire 14 and the wire roller 13 are fixedly connected.

[0057] In this embodiment, four identical arc-shaped cavities 65 are formed between the inner circle 61, the outer circle 62 and the inner and outer circle connecting part 63 on the outer winding roller block 6. The rack 22 is located in the adjacent arc-shaped cavity 65. The arc-shaped cavity 65 is used for the passage of the rack 22 and to avoid interference problems with the rack 22.

[0058] In this embodiment, flanges 27 are provided at both ends of the line roller 13, and the flanges 27 are fixedly connected to one side of the adjacent line groove 12 through fasteners. Limiting parts 28 are respectively fixed at both ends of the line roller 13, and the limiting parts 28 are used to prevent the pulling wire 14 from detaching from the line roller 13.

[0059] In this embodiment, a partition portion 29 is fixedly provided in the middle of the screw rod 9 in the length direction, and threads with opposite rotation directions are respectively provided on the left and right sides of the screw rod 9. The threads with different rotation directions can facilitate the relative movement of the two outer winding roller blocks 6 with the connecting sleeve 11 when the screw rod 9 rotates in one direction, which is convenient for control.

[0060] In this embodiment, when the support rod 16 is supported out of the storage groove 64 by the connecting rod 20, the outer surface arc of the support rod 16 is consistent with the outer surface arc of the outer circular part 62, so that when the support rod 16 is fully extended, the support effect of the support rod 16 on the paper is ensured to be the same as that of the outer winding roller block 6.

These preferred embodiments do not exhaustively describe all details, nor do they limit the present invention to specific embodiments. Obviously, many modifications and variations are possible based on the contents of this specification. These embodiments are selected and described in detail in this specification to better explain the principles and practical applications of the present invention, thereby enabling those skilled in the art to better understand and utilize the present invention.
