Abstract
Description
Technical Field
[0001] This invention relates to a device and method for quick self-alignment / quick disassembly of a roller support roller, mainly used in roller-type equipment, and belongs to the technical field of tobacco processing equipment. Background Technology
[0002] In the field of tobacco processing technology, tobacco companies typically use drum-type equipment for processes such as tobacco leaf moistening, rehydration, feeding, drying, flavoring, sieving, and sand screening. Existing equipment uses a drum placed on four sets of support rollers, which contact the drum rings at both ends of the drum to support and drive its rotation.
[0003] Existing technology adjusts the contact between the support roller and the drum ring using a screw-set seat. Turning the screw rotates the bearings at both ends of the support roller shaft, and the contact between the support roller and the drum ring is repeatedly observed for adjustment. This relies entirely on human experience and responsibility, and the line contact adjustment only achieves 50%–90% line contact in the width direction. This leads to unstable drum operation, increased lateral force, and forward / backward movement of the drum, affecting equipment stability and impacting the stability of the equipment, including the guide roller, support roller, and drum seal. The service life of the rollers is reduced. It often takes several days to adjust the forward and backward movement of the rollers, and even then, the adjustment is not complete. The line contact length between many support rollers and the roller ring does not meet the adjustment requirements of ≥90% line contact in the width direction. When replacing support rollers during equipment maintenance, the existing technology requires manual unscrewing of the fasteners, lifting and carrying the rollers through the observation window, and then lifting and carrying them down. Each set of support rollers weighs between 30 and 135 kg. Maintenance and replacement of support rollers is laborious, time-consuming, and inconvenient. It takes several hours just to disassemble a single set of support rollers.
[0004] Therefore, the key to solving the above-mentioned technical problems lies in developing a stable, reliable, time-saving, and labor-saving device and method for quick self-alignment / quick disassembly of roller support rollers. Summary of the Invention

[0085] The beneficial effects of this invention compared to the prior art are:
[0086] 1. The present invention is simple, quick and reliable to adjust, and can quickly align the support roller and the roller ring. It can effectively achieve a line contact length of ≥95% in the width direction between the support roller and the roller ring, avoid the forward and backward movement of the roller during operation, thereby improving the reliability and stability of the equipment, and thus increasing the service life of the equipment's retaining roller, support roller and roller seal ring.
[0087] 2. This invention is easy to assemble and disassemble, and can make maintenance and upkeep of the support rollers convenient, labor-saving, reduce manual labor intensity, and improve maintenance efficiency.
[0088] 3. The present invention also provides a clamping component on the support frame, which can prevent the support roller device from moving easily after adjustment, thus ensuring the stability of equipment operation.
[0089] 4. This invention is ingeniously designed. By lifting the roller, driving the positioning pad to swing 90° and insert it using a swing drive cylinder, and lowering the roller to bear the weight on the positioning pad, the roller can be placed in the actual theoretically accurate position, achieving precise roller positioning and ensuring the accuracy of the contact adjustment between the support roller and the roller's rolling circle line. This is superior to the existing technology where the roller is not lifted and the roller bears the weight on four sets of support rollers. When adjusting the contact between the support roller and the roller's rolling circle line, the displacement of the support roller causes the roller's symmetry center to shift and the roller's symmetry axis to shift from the symmetrical section of the equipment frame, resulting in reduced equipment reliability.
[0090] 5. This invention employs a support roller device installed within a guide alignment device. Rotating the adjusting handwheel causes the feed clamping device to push the support roller device along the guide limiting base plate and guide slider. The support roller device, guided by the fasteners connected to the guide slider, adaptively rotates and oscillates along the symmetrical centers of four arc-shaped waist holes, achieving a line contact adjustment between the support roller and the roller ring at a length ≥95% in the wheel width direction. This provides high line contact adjustment accuracy, superior to existing technologies that use screw sets and wrenches to turn screws and move the bearings mounted on both ends of the support roller shaft. The line contact between the support roller and the roller ring is then repeatedly adjusted by visual observation, with adjustment accuracy dependent on worker experience, and the line contact adjustment can only achieve 50%–90% line contact in the wheel width direction.
[0091] 6. This invention saves time and effort, and can achieve convenient, fast and efficient adjustment of the contact between the support roller and the roller ring line. It can complete the adjustment of a set of support rollers and roller ring line in about 15 minutes, which is better than the existing technology that takes several hours or days to complete the adjustment of the support rollers and roller ring line, and sometimes it is difficult to meet the adjustment requirements, resulting in the roller moving forward and backward.
[0092] 7. This invention uses a connecting component in conjunction with a lifting trolley. When repairing, replacing, or disassembling the support roller device, the support roller device can be easily moved out along the surface of the connecting universal ball bearing at the bottom of the fixed groove plate and slid into the limiting groove plate on the top surface of the lifting trolley. The trolley then descends, and the support roller device can be repaired or replaced. This achieves quick disassembly and assembly of the support roller device, reduces manual labor intensity, and is superior to the disassembly of support rollers in existing technologies, which require two or more people to lift, and the maintenance and replacement of support rollers is laborious, time-consuming, and inconvenient.

[0162] In this invention, the lifting hole of the bracket seat 24 is connected to the through holes of the two supporting blocks 13 below; the lifting device 2 is used to support the roller 53 to lift and lower the roller 8 when the roller ring 82 is in line contact adjustment; the driver 21 is used to drive the lifting device 22 to work, so that the lifting rod 23 lifts the bracket seat 24 up and down, and thus the roller 8 can be accurately stopped in the "﹀" shaped groove of the bracket seat 24 through the "﹀" shaped bracket seat 24.
[0163] like Figures 14 to 16 As shown, the positioning pad swing device 3 is symmetrically arranged between the two support blocks 13 on the short rods of each mounting frame 11, and can also be installed on the side of the support block 13;
[0164] The positioning pad swing device 3 includes:
[0165] The bottom of the swing drive cylinder 31 is connected to the upper surface of the short rod of the mounting frame 11.
[0166] Positioning pad 32 is connected to the rotating rod of the swing drive cylinder 31;
[0167] The positioning pad 32 has a rectangular plate-like structure, and a positioning pad slot adapted to the lifting rod 23 is provided at the non-connecting end of the positioning pad 32.
[0168] In this invention, the positioning pad swing device 3 is symmetrically arranged between the two corresponding support blocks 13 and located below the bracket seat 24. It is used to lift the roller 8 and adjust the line contact distance between the support roller 53 and the roller ring 82. During operation, after the lifting device 2 lifts the roller 8 through the bracket seat 24, the positioning pad 32 is driven to rotate by the swing drive cylinder 31, and the positioning pad 32 is rotated and placed between the support block 13 and the bracket seat 24. Then the lifting device 2 descends, so that the roller (8) and the bracket seat 24 bear the weight on the positioning pad 32, and the positioning pad 32 bears the weight on the mounting frame 11. At this time, the positioning of the roller 8 is limited to the theoretically accurate position. At this time, the alignment and line contact adjustment of the support roller and the roller ring 82 can be accurately implemented and disassembled.
[0169] Furthermore, such as Figure 17 As shown, the supporting roller device 5 includes:
[0170] The support roller seat 51 has through holes 511 at its four corners.
[0171] Roller mounting base 52 is symmetrically connected to the upper surface of the supporting roller base 51;

[0173] Roller shaft 54 is fitted with the bearing inner hole of the two roller mounting seats 52 and is supported by the roller mounting seats 52;
[0174] A drive motor 55 is mounted on one end of a roller shaft 54, and its hollow output shaft is connected to the roller shaft 54.
[0175] Among them, the supporting roller seat connection hole 511 is an arc-shaped waist hole, and the four arc-shaped waist holes are arranged in a ring; the roller mounting seat 52 is a roller mounting seat with bearings; the drive motor 55 is located on the inner side of the mounting frame 11, and the drive motor 55 is a geared motor.
[0176] In this invention, the support roller device 5 is used to support and drive the rotation of the roller 8. The support roller device 5 is installed above the center of the guide self-aligning device 4. The bottom of the support roller seat 51 has four support roller seat connection holes 511. When the support roller 53 is self-aligned and in line contact with the roller ring 82, the support roller device 5 can rotate and swing within a certain size range along the symmetrical center of the four support roller seat connection holes 511, so that the support roller 53 and the roller ring 82 can be adaptively fitted in line contact. The drive motor 55 is used to drive the roller shaft 54 to rotate, which in turn drives the support roller 53 to rotate, thereby driving the roller ring 82 in contact with the support roller 53 to rotate, and thus driving the roller 8 to rotate.
[0177] Furthermore, such as Figure 18 and Figure 19 As shown, the guide alignment device 4 is symmetrically arranged above both ends of the short rod of the mounting frame 11; the guide alignment device 4 includes:
[0178] The guide limiting base plate 41 has guide limiting base plate connection holes 411 at each of its four corners, which work in conjunction with the connection holes 511 of the support roller seat;
[0179] Guide sliders 42 are installed in the connecting holes 411 of the guide limiting base plate;
[0180] The lower part of the feed clamping device 43 is connected to one end of the guide limiting base plate 41, and the working end of the feed clamping device 43 is connected to the support roller seat 51.
[0181] The lower end of the support roller seat 51 is connected to the guide slider 42 by a fastener passing through the support roller seat connection hole 511.
[0182] In this invention, the feed clamping device 43 is located near the end of the long rod of the mounting frame 11; the guide slider 42 is machined with threaded holes and bosses, and is used not only as a slider but also as a nut fastener when the support roller 53 is in line contact with the roller ring 82 and adjusted, the support roller seat 51 is locked by fasteners.
[0183] Furthermore, such as Figure 19 As shown, the guide limiting base plate 41 has a recessed part in the middle that works in conjunction with the support roller seat 51, and the four outer corners of the guide limiting base plate 41 also have fixing holes that connect to the support frame 1.
[0184] The guide limiting base plate connection hole 411 is opened at the four corners of the recess, and the guide limiting base plate connection hole 411 is a rectangular groove.
[0185] The guide slider 42 has an overall "convex" shaped structure, and the guide slider 42 has a threaded hole.
[0186] The feed clamping device 43 includes:
[0187] The support seat is connected to the upper surface of the guide and limit base plate 41, and the support seat has a mounting threaded hole for the feed connecting rod.
[0188] Adjust the handwheel, which is connected to one end of the feed linkage;
[0189] The feed link is connected to the support seat via a thread;
[0190] The hinged seat has one end connected to the feed connecting rod and the other end connected to the support roller seat 51.
[0191] Among them, rotating the adjustment handwheel drives the feed linkage to move the hinge seat forward or backward toward the direction of the drum 8.
[0192] In this invention, the fastener is a fastening bolt. Four rectangular grooves are machined on the guide limiting base plate 41. The guide slider 42 is installed in the connecting hole 411 of the guide limiting base plate. The four arc-shaped connecting holes 511 of the support roller seat 51 are fitted onto the fastening bolts connected to the guide slider 42. The support roller device 5 can move along the rectangular groove 42 with the connected guide slider 42 within a certain size range. At the same time, the support roller device 5 can also rotate and swing adaptively within a certain size range along the symmetrical center of the four guide limiting base plate connecting holes 411. The guide self-aligning device 4 is connected to the mounting frame 11 through the fixing hole of the guide limiting base plate 41 by the locking bolt. The operator drives the feed linkage to move the hinge seat forward or backward toward the roller 8 by rotating the adjustment handwheel, thereby driving the support roller device 5 to move within a certain size range.
[0193] In this invention, a limiting component 9 is also included. The limiting component 9 is connected to the middle of the guide limiting base plate 41 near the end of the long rod of the mounting frame 11. The limiting component 9 includes a limiting screw, a locking nut, and a threaded connection hole. The limiting component 9 is used to manually push the support roller device 5 from the lifting trolley 7 into the guide self-aligning device 4 until it contacts the limiting screw of the limiting component 9, indicating that the support roller device 5 has been pushed into place, and is used as a limiting component.
[0194] In summary, a more specific embodiment of the present invention is as follows:
[0195] Specifically, the method for self-aligning the support roller 53 and the roller ring 82 includes the following steps:
[0196] 1. The operator first controls the lifting device 2 to lift the roller 8;
[0197] 2. The operator loosens the fasteners on the support roller device 5 and moves the support roller device 5 outward a certain distance;
[0198] 3. The operator controls the positioning pad swing device 3 to rotate the positioning pad 32 to the upper part of the support block 13 and below the bracket seat 24;
[0199] 4. The operator controls the lifting device 2 to descend, so that the roller 8 and the bracket seat 24 are supported on the positioning pad 32, thus achieving the positioning of the roller 8 in the actual theoretical accurate position.
[0200] 5. The operator rotates the adjusting handwheel of the adjusting guide self-aligning device 4 to make the supporting roller device 5 fit against the roller ring 82 until the adjusting handwheel is obviously difficult to turn.
[0201] 6. The operator shall lock and fix the support roller device 5 to the guide self-aligning device 4 with fasteners;
[0202] 7. The operator controls the lifting device 2 to lift the roller 8;
[0203] 8. The operator controls the positioning pad swing device 3 to rotate the positioning pad 32 to reset it;
[0204] 9. The operator controls the lifting device 2 to descend until the roller 8 is supported on the four support roller devices 5 and the bracket seat 24 is lower than the bottom of the roller 8, thus completing the alignment of the support rollers 53 and the roller ring 82.
[0205] A quick disassembly method for the support roller device 5, the method comprising the following steps:
[0206] 1. The operator first moves the lifting trolley 7 to below the support roller device 5 that needs to be disassembled;
[0207] 2. The operator controls the lifting trolley 7 to raise the limiting groove plate 71 to a position flush with the fixed groove plate 61;
[0208] 3. The operator shall connect and lock the connecting buckle 73 on the limiting groove plate 71 to the connecting latch 63 on the fixing groove plate 61 respectively.
[0209] 4. The operator controls the lifting device 2 to lift the roller 8;
[0210] 5. The operator can loosen the fasteners on the support roller device 5 that needs to be disassembled, and then move the support roller device 5 that needs to be disassembled onto the limit groove plate 71 along the direction of the limit groove plate 71.
[0211] 6. The operator loosens the connecting buckles 73 and connecting latches 63 on both sides respectively, thereby separating the limiting groove plate 71 and the fixing groove plate 61;
[0212] 7. The operator controls the lifting trolley 7 to lower the support roller device 5, and then the disassembled support roller device 5 can be sent to the designated location for maintenance, thus completing the quick disassembly of the support roller device 5.
[0213] In this invention, the swing drive cylinder 31 is a swing drive cylinder with a rotation function. The swing drive cylinder 31 drives the positioning pad 32 to swing and be inserted at 90°. The control of the swing cylinder can also be ≥90° swing insertion, and the positioning pad 32 can also be ≤90° swing insertion. It can be set according to the initial position of the positioning pad 32. An electric driver or a linear driver can also be used to drive the positioning pad 32 to be inserted.
[0214] During use, after the lifting device 2 lifts the roller 8, the positioning pad swing device 3 drives the positioning pad 32 to rotate to below the bracket seat 24. When the lifting device 2 descends, the roller 8 and the bracket seat 24 bear the weight on the positioning pad 32. At this time, the roller 8 is at the actual theoretical accurate height position. The precise adjustment can be carried out by the support roller 53 and the roller ring 82 to align and make line contact. At this time, the weight of the roller 8 is entirely borne on the positioning pad 32.
[0215] Another function of the positioning pad 32 of the present invention is that when the equipment is stopped, the roller 8 can be supported on the positioning pad 32, so as to avoid the support roller 53 being indented due to the long-term shutdown of the equipment, which would affect the stability of the equipment operation.
[0216] When the support roller device 5 moves along the connecting assembly 6 to the lifting trolley 7, the limiting groove plate 71 has a guide groove and is equipped with a trolley universal ball bearing 72, which is intended to guide the support roller device 5 and reduce sliding friction when it moves.
[0217] The positioning pad swing device 3 functions as a positioning device, used to position the roller 8 at the theoretical standard height position. When the support roller 53 and the roller ring 82 are aligned and in line contact, if the roller reference position is correct, and the alignment and line contact adjustment process and structure are reasonable and correct, then the result after implementation will be correct and appropriate.
[0218] Without the positioning pad swing device 3, the height position of the roller 8 will change when the support roller 53 is released; if the lifting device lifts the roller, the height position of the roller will also change. Unless the lifting device can be precisely controlled to achieve the highest position, the self-aligning position, and the lowest position reliably and intuitively, the positioning pad swing device 3 can be omitted.
[0219] The swing drive cylinder 31 is the driving element of the positioning pad 32. In this solution, it is a rotary cylinder or an angle cylinder, but an electric actuator can also be used.
[0220] a) Current situation: When the equipment is stopped for maintenance or replacement of the support rollers, the rollers need to be lifted up to ensure that the roller ring and the support rollers are not in contact. When the equipment is about to start or the replaced support rollers are installed, the rollers are lifted up and lowered onto the support rollers. However, whether the support rollers are tilted to the left or right or wobble forward or backward can only be observed after the rollers are on the support rollers and running. If they are not suitable, they can only be adjusted while running. To solve this problem, positioning pads and support roller guide self-aligning devices are added. When the support rollers need to be aligned or the machine is stopped, the positioning pads 32 are inserted to position the rollers at the theoretical size position. This function can only be achieved when the rollers are placed below the bracket seat 24. Placing them above the bracket seat will not achieve this function.
[0221] b) The dimensions of the pads are consistent across four pieces. According to the design calculations, the pads are rotated and placed on the support block 13 of the frame 11. The height of the pad 32 plus the height of the bracket seat 24 ensures that when the roller 8 is placed on the bracket seat 24, the outer circle of its rolling ring 82 is in contact with the outer circle of the support roller 53. In other words, the roller 8 and the bracket seat 24 bear the weight of the positioning pad 32, and the pad 32 bears the weight of the support block 13 of the frame 11. At this point, the roller 8 is at its theoretically accurate height. During assembly, the positioning pad 32 is placed on the support block 13 first, then the bracket seat 24 is placed on the positioning pad 32, and then the roller 8 is placed on the bracket seat 24. Finally, the support roller is installed using the self-aligning method of this patent, ensuring good contact between the support roller and the roller's rolling ring line.
[0222] c) When the equipment is in operation, the roller 8 rotates and the roller 8 bears the weight on the support roller 5, which in turn bears the weight on the frame 11. At this time, the pad block 32 is reset and does not bear any weight.
[0223] d) When the support roller 5 is quickly aligned, disassembled, or stopped, the positioning pad 32 rotates and is placed on the support block 13, the bracket seat 24 falls on the positioning pad, the roller 8 and the bracket seat 24 finally bear the weight on the positioning pad 32, the positioning pad 32 bears the weight on the support block 13, and the support block 13 then bears the weight on 11.
[0224] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the protection scope of the present invention.
