Description

Technical Field

[0001] The invention relates to a device and method for rapid centering and alignment / rapid disassembly of a roller supporting roller, which is mainly used for roller equipment and belongs to the technical field of tobacco processing equipment. Background Art

[0002] Generally speaking, in the field of tobacco processing technology, tobacco companies use roller equipment for processes such as leaf conditioning, moisture conditioning, feeding, drying, flavoring, screening, and sand screening. Existing equipment uses a roller mounted on four sets of support rollers. The support rollers contact the roller rings at each end of the roller, supporting and driving the roller's rotation.

[0003] The existing technology uses a screw top screw seat to adjust the contact between the support roller and the roller ring. The screw is turned to rotate, and the seat bearings at both ends of the support roller shaft are pushed to move. The contact between the support roller and the roller ring is observed and adjusted repeatedly, that is, the alignment of the support roller and the roller ring is observed. It depends entirely on human experience and responsibility. The line contact adjustment between the support roller and the roller ring can only achieve 50% to 90% line contact in the wheel width direction, resulting in unstable operation of the roller and increased movement force. The roller moves forward and backward, affecting the stability of the equipment, and the equipment blocking wheel, support roller, and roller sealing ring. The service life of the roller is shortened. It often takes several days to debug the front and rear movement of the roller, and it cannot be fully debugged. The linear contact length between many support rollers and the roller ring does not meet the debugging requirement of linear contact ≥90% in the wheel width direction. When the support rollers are replaced during equipment maintenance, the existing technology requires manual unscrewing of the installation fasteners, and two or more people lift and lift them, lift them out through the observation window, and then lift and lift them down. Each set of support rollers weighs 30 to 135 kg. Maintenance and replacement of support rollers is laborious, time-consuming, and inconvenient. It takes several hours to remove the next set of support rollers.

[0004] Therefore, the key to solving the above technical problems is to develop a stable, reliable, time-saving and labor-saving device and method for quickly aligning and aligning / quickly disassembling the roller support roller. Summary of the Invention

[0005] In view of the many defects and shortcomings in the above-mentioned background technology, the present invention has made improvements and innovations thereto, with the aim of providing a device for quick centering and alignment / quick disassembly of a roller support roller that is simple to adjust, quick and reliable, capable of realizing quick centering and alignment of the support roller and the roller ring, effectively achieving a line contact length of ≥95% between the support roller and the roller ring in the direction of the wheel width, avoiding forward and backward movement of the roller during operation, thereby improving the reliability and stability of the equipment, and further increasing the service life of the equipment's stop wheel, support roller, and roller sealing ring.

[0085] The beneficial effects of the present invention compared with the prior art are:

[0086] 1. The present invention is simple, fast and reliable to adjust, and can realize the rapid centering and alignment of the support roller and the drum ring, effectively achieving the line contact length of the support roller and the drum ring ≥ 95% in the wheel width direction, avoiding the forward and backward movement of the drum during operation, thereby improving the reliability and stability of the equipment, and further increasing the service life of the equipment's stopper wheel, support roller, and drum sealing ring;

[0087] 2. The present invention is easy to disassemble and assemble, which can achieve convenience, save labor, reduce labor intensity and improve maintenance efficiency when maintaining the support roller;

[0088] 3. The present invention also provides a tightening assembly on the support frame, which can prevent the supporting roller device from moving easily after adjustment, thereby ensuring the stability of the equipment operation.

[0089] 4. The present invention is cleverly designed. By lifting the drum, swinging the drive cylinder to drive the positioning pad 90 degrees and inserting it, and then lowering the drum to bear the weight on the positioning pad, the drum can be placed in the actual theoretical accurate position, achieving precise drum positioning and ensuring the accuracy of the adjustment of the linear contact between the support rollers and the drum rolling circle. This is superior to the existing technology in which the drum is not lifted and the drum bears the weight on four sets of support rollers. When the linear contact between the support rollers and the drum rolling circle is adjusted, the displacement of the support rollers changes, resulting in the deviation of the drum's symmetry center and the deviation of the drum's symmetry axis from the symmetric section of the equipment frame, which reduces the reliability of the equipment operation.

[0090] 5. The present invention adopts a support roller device installed in the guide centering and alignment device, and rotates the adjustment hand wheel to make the feed clamping device push the support roller device to move along the guide limit base plate and the guide slider. The fastener connected to the guide slider of the support roller device serves as a guide, and adaptively rotates and swings along the symmetrical center of the four arc-shaped waist holes, so that the support roller is pressed and the line contact with the roller ring is adjusted to ≥95% of the length in the wheel width direction. The line contact adjustment accuracy is high; it is superior to the prior art that uses screw top screw seat, and the wrench is used to turn the screws to push the seat bearings sleeved on both ends of the support roller shaft to move. The line contact between the support roller and the roller ring is observed by naked eyes to make repeated adjustments. The adjustment accuracy depends on the worker's debugging experience, and its line contact adjustment can only achieve a line contact of 50% to 90% of the length in the wheel width direction;

[0091] 6. The present invention saves time and effort, and can achieve convenient, rapid and efficient adjustment of the linear contact between the support roller and the roller circle. A set of linear contact adjustments between the support roller and the roller circle can be completed in about 15 minutes, which is superior to the existing technology that takes several hours or even days to complete the linear contact adjustment between the support roller and the roller circle, and sometimes it is difficult to meet the adjustment requirements, resulting in the roller moving forward and backward.

[0092] 7. The present invention adopts a connecting component for use with a lifting trolley. When repairing, replacing and disassembling the supporting roller device, the supporting roller device can be easily moved out along the connecting universal ball bearing surface 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 descends and then the supporting roller device is repaired and replaced, so that the supporting roller device can be quickly disassembled and assembled and the labor intensity can be reduced. This is superior to the disassembly of the supporting roller in the prior art, which requires two or more people to lift, and the maintenance and replacement of the supporting roller is laborious, time-consuming and inconvenient.

[0194] In summary, a more specific embodiment of the present invention is:

[0195] Specifically, the method for aligning the support roller 53 and the drum ring 82 includes the following steps:

[0196] 1. The operator first controls the lifting device 2 to lift the drum 8;

[0197] 2. The operator loosens the fasteners on the support roller device 5 and moves the support roller device 5 outward for a 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 jacking device 2 to descend, so that the roller 8 and the bracket seat 24 are supported on the positioning pad 32, that is, the roller 8 is positioned in the actual theoretical accurate position;

[0200] 5. The operator turns the adjusting hand wheel of the guide aligning device 4 to make the supporting roller device 5 fit closely to the drum roller ring 82 until the adjusting hand wheel becomes noticeably difficult to turn.

[0201] 6. The operator locks and fixes the supporting roller device 5 and the guide centering and alignment device 4 through fasteners;

[0202] 7. The operator controls the lifting device 2 to lift the drum 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 drum 8 is supported on the four supporting roller devices 5 and the bracket seat 24 is lower than the bottom end of the drum 8, thus completing the alignment of the supporting rollers 53 and the drum ring 82;

[0205] A method for quickly disassembling the supporting roller device 5 comprises the following steps:

[0206] 1. The operator first moves the lifting trolley 7 to the bottom of the support roller device 5 where it is necessary to remove it;

[0207] 2. The operator controls the lifting trolley 7 to lift the limiting slot plate 71 to a position flush with the fixed slot plate 61;

[0208] 3. The operator connects and locks the connecting buckle 73 on the limiting slot plate 71 and the connecting buckle 63 on the fixed slot plate 61;

[0209] 4. The operator controls the lifting device 2 to lift the drum 8;

[0210] 5. The operator loosens the fasteners on the support roller device 5 to be removed, and then moves the support roller device 5 to be removed onto the limit slot plate 71 along the direction of the limit slot plate 71;

[0211] 6. The operator loosens the connecting buckles 73 and the connecting buckles 63 on both sides respectively, separating the limiting slot plate 71 and the fixed slot plate 61;

[0212] 7. The operator controls the lifting trolley 7 to drive the supporting roller device 5 to descend, and then the disassembled supporting roller device 5 can be sent to a designated location for maintenance, thus completing the rapid disassembly of the supporting roller device 5.

[0213] In the present invention, the swing drive cylinder 31 is a swing drive cylinder 31 with a rotation function. The swing drive cylinder 31 drives the positioning pad 32 to swing 90° and insert. The swing cylinder can also be controlled to swing ≥90° and insert. The positioning pad 32 can also be swing ≤90° and insert. It can be set according to the initial position of the positioning pad 32. An electric drive or a linear drive can also be used to drive the positioning pad 32 to insert.

[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 the bottom of 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, and the support roller 53 and the roller ring 82 can be used to align the center and line contact to accurately implement the adjustment. At this time, the weight of the roller 8 is fully borne on the positioning pad 32.

[0215] Another function of the positioning pad 32 of the present invention is that when the equipment is shut down, the roller 8 can bear the weight on the positioning pad 32, avoiding the bearing of the weight on the support roller 53 due to long-term shutdown of the equipment, resulting in indentation of the support roller 53 and affecting the stability of the equipment operation.

[0216] When the supporting roller device 5 moves out to the lifting trolley 7 along the connecting assembly 6, the limiting slot plate 71 has a guide groove and is provided with a trolley universal ball bearing 72, the purpose of which is to guide the supporting roller device 5 when moving and reduce sliding friction.

[0217] The positioning pad swing device 3 functions as a positioning device, which is used to position the roller 8 so that it is at a theoretical standard height position, so that the support roller 53 and the roller ring 82 are aligned and adjusted in line contact. If the roller reference position is correct, the alignment and line contact adjustment implementation process and structure are reasonable and correct, then the result after implementation will be correct and appropriate.

[0218] If there is no positioning pad swinging device 3, the height position of the roller 8 will change when the supporting roller 53 is loosened; if the lifting device lifts the roller, the height position of the roller will also change, unless the lifting device can be accurately controlled to reach the highest position, the centering position, and the lowest position can be implemented reliably and intuitively, then the positioning pad swinging device 3 can be unnecessary.

[0219] The swing drive cylinder 31 is a driving element for the positioning pad 32. In this embodiment, it is a rotary cylinder or an angle cylinder, but it can also be implemented by an electric actuator.

[0220] a) Current situation: When the equipment is shut down, repaired or the support roller is replaced, the drum must be lifted up so that the drum ring and the support roller are at a certain distance from each other and do not contact each other. When the equipment is to be started or the replaced support roller is installed, the drum is lifted up and lowered onto the support roller. However, whether the support roller is installed with left and right tilt or front and back tilt can only be observed after the drum falls onto the support roller and runs. If it is not suitable, it can only be adjusted while running. To solve this problem, positioning pads and support roller guide centering and alignment devices are added. When the support roller is to be aligned or shut down, the positioning pads 32 are inserted. The drum is positioned at the theoretical size position and can only be placed below the bracket seat 24 to achieve this function. This function cannot be achieved by placing it above.

[0221] b) The dimensions of the four spacers are machined uniformly. According to the design calculations, the spacers are rotated and placed on the support block 13 of the frame 11. The height of the spacers 32 + the height of the bracket 24 ensure that when the drum 8 is placed on the bracket 24, the outer circumference of its rolling ring 82 exactly contacts the outer circumference of the support roller 53. In other words, the drum 8 and the bracket 24 bear the weight of the positioning spacers 32, and the spacers 32 bear the weight of the support block 13 of the frame 11. At this point, the drum 8 is at the actual theoretically accurate height position. During assembly, the positioning spacers 32 are first placed on the support block 13, the bracket 24 is placed on the positioning spacers 32, and then the drum 8 is placed on the bracket 24. The support rollers are then installed according to the support roller centering and alignment method of this patent to achieve good linear contact between the support rollers and the drum rolling rings.

[0222] c) When the equipment is in operation, the roller 8 rotates, and the roller 8 bears weight on the supporting roller 5, and the supporting roller 5 bears weight on the frame 11. At this time, the pad 32 is reset and does not bear weight.

[0223] d) When the support roller 5 is quickly aligned, disassembled or shut down, the positioning pad 32 is rotated and placed on the support block 13, and 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 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 does not constitute any other limitation thereto. Any person skilled in the art may utilize the above-disclosed technical content to modify or modify the present invention into equivalent embodiments. However, any simple modifications, equivalent variations, and modifications to the above embodiments that do not depart from the technical content of the present invention and are based on the technical essence of the present invention remain within the scope of protection of the present invention.
