Description

Technical Field

[0001] This utility model relates to the field of forming guide roller technology for papermaking machines, and more specifically, it relates to a forming guide roller for papermaking machines. Background Technology

[0002] In the papermaking industry, forming guide rollers are key components of papermaking machines. Their installation structure and adjustment functions directly affect production efficiency and paper quality. However, forming guide rollers currently on the market still have many technical defects in practical applications. These problems not only affect the maintenance efficiency of the equipment, but also reduce the flexibility of production.

[0003] The primary problem is the inconvenience of disassembling and assembling the guide rollers. Existing forming guide rollers have significant defects: First, the installation structure of the guide rollers is complex and requires the use of various specialized tools for operation; second, the disassembly and assembly process involves many steps, increasing maintenance time; third, the operation process requires a lot of manpower, increasing labor intensity. This structural design deficiency not only affects the maintenance efficiency of the equipment, but may also bring additional labor costs and equipment wear and tear.

[0004] More prominently, the guide rollers lack stability. Although some improved forming guide rollers have added quick assembly and disassembly functions, their structures have obvious problems: First, the simple fixed structure is easily affected by the vibration generated when the guide rollers rotate; second, the vibration may cause the fixed structure to loosen and shift; third, the loose structure will affect the running accuracy of the guide rollers; in addition, unstable installation may also cause abnormal wear of the equipment. This design deficiency not only affects the operating stability of the equipment, but may also bring safety hazards and increased maintenance costs.

[0005] Most critically, the guide roller height adjustment function is missing. The existing forming guide roller has obvious defects: First, the installation height of the guide roller is fixed and cannot be adjusted according to production needs; second, the fixed height limits the adaptability of the equipment to different specifications of products, and the fixed height may also affect the quality control of finished paper. This structural design deficiency not only limits the scope of application of the equipment, but may also affect the quality of the final product. Utility Model Content

[0017] (III) Beneficial Effects

[0018] Compared with the prior art, the present invention provides a forming guide roller for a papermaking machine, which has the following beneficial effects:

[0019] 1. The quick-change device constructs a convenient disassembly and assembly system through the precise cooperation of the abutment sleeve, abutment rod, switching sleeve, abutment groove, moving ball, moving groove and switching groove. The concave moving groove design provides a stable rolling space for the moving ball, and the setting of the switching groove ensures smooth disassembly and assembly. This design realizes the quick disassembly and assembly of the guide roller through the cooperation of the moving ball and the abutment groove, effectively solving the problem of cumbersome disassembly and assembly of guide rollers in traditional equipment.

[0020] 2. The locking mechanism constructs a reliable locking system through the coordinated action of components such as the driven wheel, moving rod, rotating sleeve, and driving wheel.

[0031] Please see Figures 1-5 A forming guide roller for a papermaking machine includes a guide roller 1, with mounting seats 2 on both sides of the guide roller 1. A quick-change device is mounted on the mounting seats 2. The quick-change device includes an abutment sleeve 3, an abutment rod 4, a switching sleeve 5, an abutment groove 6, a moving ball 7, a moving groove 8, and a switching groove 9. The abutment sleeve 3 is detachably fitted on the outside of the abutment rod 4, the switching sleeve 5 is slidably fitted on the outside of the abutment sleeve 3, the abutment groove 6 is opened on the outside of the abutment rod 4, the moving ball 7 is rotatably installed in the moving groove 8, the moving groove 8 is opened on the side wall of the abutment sleeve 3, the switching groove 9 is opened on the inside of the switching sleeve 5, and a locking mechanism is provided on the outside of the abutment sleeve 3. The locking mechanism includes a driven wheel 10, a moving rod 11, a rotating sleeve 12, and a driving wheel 13. The driven wheel 10 is fixedly connected to the outside of the rotating sleeve 12, the moving rod 11 is fixedly connected to one side of the switching sleeve 5, the rotating sleeve 12 is movably fitted on the outside of the moving rod 11 by a thread, and the driving wheel 13 meshes with the driven wheel 10. An adjustment device is provided on the outside of the mounting seat 2.

[0032] The adjustment device includes a sliding frame 14, a hydraulic rod 15, a hydraulic cylinder 16, and a fixed frame 17. The hydraulic cylinder 16 is detachably installed inside the fixed frame 17. The bottom end of the hydraulic rod 15 is connected to the output end of the hydraulic cylinder 16, and the top end of the hydraulic rod 15 is detachably connected to the sliding frame 14. The mounting base 2 is detachably installed on the sliding frame 14.

[0033] The fixed frame 17 is fixedly provided with a slide rail 18, and the sliding frame 14 is slidably provided on the outside of the slide rail 18. The sliding frame 14 is rotatably provided with a roller 19, and the two sides of the slide rail 18 respectively contact the corresponding roller 19.

[0034] The guide roller 1 has slots 20 at both ends, and the mounting base 2 has a detachable locking block 21. One side of the locking block 21 is connected to a bearing sleeve 22, and the other side of the bearing sleeve 22 is connected to a plug rod 23, which is inserted into the slot 20.

[0035] In this embodiment, when it is necessary to adjust the height of the guide roller 1, two hydraulic cylinders 16 are opened simultaneously. The hydraulic cylinders 16 drive the hydraulic rods 15 to push the sliding frame 14 to slide along the slide rail 18 set in the fixed frame 17. At the same time, the sliding frame 14 drives the inner rollers 19 to roll, so that the sliding frame 14 drives the guide roller 1 to rise and fall through the mounting base 2. After the height is adjusted appropriately, the hydraulic cylinders 16 are closed simultaneously.

[0036] Please see Figure 4 and Figure 5 As a further implementation of the overall equipment: a control sleeve 24 is fixedly provided on one side of the drive wheel 13, and the control sleeve 24 is rotatably installed on the outside of the abutment sleeve 3.

[0037] A fixing plate 25 is fixedly provided on the outside of the abutting sleeve 3, and multiple rotating sleeves 12 are rotatably installed on the fixing plate 25. Multiple moving rods 11 are fixedly connected to one side of the switching sleeve 5.

[0038] The movable groove 8 has a concave structure design.

[0039] The abutment groove 6 is a ring-shaped structure located on the outside of the abutment rod 4.

[0040] More specifically, when the guide roller 1 needs to be replaced, first rotate the control sleeve 24 in the forward direction. The control sleeve 24 drives the drive wheel 13 connected to one side to rotate. Then, the drive wheel 13 drives the driven wheel 10 meshing with it to rotate synchronously. Then, the driven wheel 10 drives multiple rotating sleeves 12 to rotate synchronously on the fixed plate 25. Since the rotating sleeve 12 is movably connected to the moving rod 11 through threads, the moving rod 11 drives the switching sleeve 5 to slide. Then, the switching sleeve 5 drives the switching groove 9 opened on the inner side to slide. When the switching groove 9 moves to the position corresponding to the moving groove 8, stop rotating the control sleeve 24. Then, pull the abutting sleeve 3 and the abutting rod 4 to both ends respectively. Then, the inner wall of the abutting groove 6 presses against the outer wall of the moving ball 7. Then, the moving ball 7 rolls in the moving groove 8, so that the moving ball 7 rolls out of the abutting groove 6 and a part of the moving ball 7 rolls into the switching groove 9. Then, remove the abutting sleeve 3 and the abutting rod 4, and then drive the guide roller 1 to lock. The components such as block 21 and bearing sleeve 22 are lifted upwards, and then the bearing sleeve 22 and the locking block 21 are pushed apart to both ends, so that the insertion rod 23 is pulled out from the slot 20. Then the guide roller 1 is replaced, and then the insertion rod 23 connected to one side of the bearing sleeve 22 is reinserted into the slot 20. Then the locking block 21 is reinstalled on the mounting base 2, and then the locking rod is passed through the mounting base 2. Then the locking sleeve is re-fitted onto the outside of the locking rod, and then the control sleeve 24 is rotated in the reverse direction. The control sleeve 24 drives the driving wheel 13 connected to one side to rotate in the reverse direction, so that the driving wheel 13 drives the rotating sleeve 12 to rotate in the reverse direction on the fixed plate 25 through multiple driven wheels 10. Then the moving rod 11 drives the switching sleeve 5 to slide and reset in the reverse direction. Then the inner wall of the switching groove 9 presses against the outer wall of the moving ball 7, so that the moving ball 7 rolls out of the switching groove 9 and is re-locked into the abutment groove 6. The switching sleeve 5 is limited by the cooperation of the moving rod 11 and other components, ensuring stable installation.

[0041] In summary, when the overall equipment is in use or running: when it is necessary to adjust the height of the guide roller 1, the two hydraulic cylinders 16 are opened simultaneously. The hydraulic cylinders 16 drive the hydraulic rods 15 to push the sliding frame 14 to slide along the slide rail 18 set in the fixed frame 17. At the same time, the sliding frame 14 drives the inner rollers 19 to roll, so that the sliding frame 14 drives the guide roller 1 to rise and fall through the mounting base 2. After the height is adjusted appropriately, the hydraulic cylinders 16 are closed simultaneously.

[0042] When the guide roller 1 needs to be replaced, first rotate the control sleeve 24 in the forward direction. The control sleeve 24 drives the drive wheel 13 connected to one side to rotate. Then, the drive wheel 13 drives the driven wheel 10 meshing with it to rotate synchronously. Then, the driven wheel 10 drives multiple rotating sleeves 12 to rotate synchronously on the fixed plate 25. Since the rotating sleeve 12 is movably connected to the moving rod 11 through threads, the moving rod 11 drives the switching sleeve 5 to slide. Then, the switching sleeve 5 drives the switching groove 9 opened on the inner side to slide. When the switching groove 9 moves to the position corresponding to the moving groove 8, stop rotating the control sleeve 24. Then, pull the abutting sleeve 3 and the abutting rod 4 to both ends respectively. Then, the inner wall of the abutting groove 6 presses against the outer wall of the moving ball 7. Then, the moving ball 7 rolls in the moving groove 8, so that the moving ball 7 rolls out of the abutting groove 6 and a part of the moving ball 7 rolls into the switching groove 9. Then, remove the abutting sleeve 3 and the abutting rod 4. Then, the guide roller 1 drives the locking block 2. Components such as bearing sleeve 22 are lifted upwards, and then bearing sleeve 22 and locking block 21 are pushed apart to both ends, so that the insertion rod 23 is pulled out from the slot 20. Then, guide roller 1 is replaced, and then the insertion rod 23 connected to one side of bearing sleeve 22 is reinserted into slot 20. Then, locking block 21 is reinstalled on mounting base 2, and then locking rod is passed through mounting base 2. Then, locking sleeve is re-fitted onto the outside of locking rod, and then control sleeve 24 is rotated in the reverse direction. Control sleeve 24 drives the drive wheel 13 connected to one side to rotate in the reverse direction, so that drive wheel 13 drives rotating sleeve 12 to rotate in the reverse direction on fixed plate 25 through multiple driven wheels 10. Then, moving rod 11 drives switching sleeve 5 to slide and reset in the reverse direction. Then, the inner wall of switching groove 9 presses against the outer wall of moving ball 7, so that moving ball 7 rolls out of switching groove 9 and is re-locked into abutment groove 6. Through the cooperation of moving rod 11 and other components, the switching sleeve 5 is limited, ensuring stable installation.

[0043] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this utility model.
