Description

Technical Field

[0001] The invention relates to the technical field of corrugated rollers, and in particular to a gap-adjustable corrugated roller. Background Art

[0002] Corrugating rollers are the core components of single-facers in corrugated cardboard production equipment. They belong to the category of packaging machinery accessories and are widely used in corrugated cardboard production lines. Their main function is to pressurize and form corrugated base paper through the meshing transmission of upper and lower rollers. During use, if the gap between the corrugating rollers is too large, the corrugations will become loose, while if the gap is too small, the paper fibers will be crushed. Therefore, adjusting the gap between the corrugating rollers is a core operation in the corrugated cardboard production line, which directly affects the cardboard forming quality, bonding strength and equipment life.

[0003] In the related art, in order to facilitate the adjustment of the gap of the corrugating roller, for example, the patent with the prior art publication number CN220280726U provides an adjustable gap corrugating roller, which is used in conjunction with a limit seat, a two-way threaded rod, a movable shaft, a movable rod, a limit guide rail, a connecting rod and a connecting shaft. After rotating the two-way threaded rod, the connecting rod can be moved accordingly, and the connecting rod moves accordingly on the outer surface of the limit guide rail, so that the spacing between the upper and lower movable shafts changes, thereby changing the spacing between the lower corrugating roller and the upper corrugating roller, thereby achieving the purpose of adjustable gap. Through the transmission gear, the driving gear and the motor, after starting the motor, under the transmission of the transmission gear and the driving gear, the driving gears on the outer surfaces of the upper and lower movable shafts rotate in opposite directions and at the same speed, thereby facilitating the lower corrugating roller and the upper corrugated roller to fully and effectively press the corrugated paper into corrugated base paper, thereby solving the problem that the gap is not convenient to adjust.

[0004] Although the above-mentioned existing technical solutions can facilitate the adjustment of the gap between the corrugating rollers, during actual use, the gap between the two corrugating rollers will change due to the wear of the corrugating rollers themselves and the shaft ends, and the parallelism between the two corrugating rollers will be affected. As a result, the gap and parallelism of the corrugating rollers cannot be detected during the processing, and it is difficult to ensure the processing quality of corrugated paper.

[0020] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0021] The present invention will be further described below with reference to the embodiments.

[0022] See also Figures 1-12 The present invention provides a technical solution: a gap-adjustable corrugated roller, comprising a fixed seat 1, a movable seat 2, a roller body 3, a connecting plate 4 and a detection component 6, the movable seat 2 is located at the top of the fixed seat 1, and is driven by an external force to adjust the distance between it and the fixed seat 1; the roller body 3 is respectively installed on the top of the fixed seat 1 and the movable seat 2, and the two roller bodies 3 can adjust the processing gap under the drive of the movable seat 2; the connecting plate 4 is coaxially installed at both ends of the roller body 3, and a detection groove 41 is opened on the outer side of the connecting plate 4; the detection component 6 is symmetrically arranged on the top of the fixed seat 1 and the movable seat 2 at both ends of each roller body 3, for detecting the parallelism of the roller body 3; wherein the detection component 6 includes a first wheel seat 61, a roller 62 is rotatably provided on the inner side of the first wheel seat 61, and the roller 62 is attached to the outer side of the connecting plate 4 corresponding to the detection groove 41, and an annular pressure sensor 66 is provided on the side of the first wheel seat 61 away from the connecting plate 4, for detecting the pressure exerted on the roller 62.

[0023] Specifically, a first slide rod 63 is fixedly provided on the side of the first wheel seat 61 away from the connecting disk 4, a mounting seat 64 is slidingly provided on the outside of the first slide rod 63, the mounting seat 64 is fixed on the top of the fixed seat 1 and the movable seat 2, an annular pressure sensor 66 is fixed on the outside of the mounting seat 64, a first elastic member 65 is provided on the top of the annular pressure sensor 66, and the first elastic member 65 is located on the outside of the first slide rod 63.

[0024] When adjusting the gap between the two roller bodies 3, the movable seat 2 is driven by external force to drive the upper roller body 3 to move up and down, so that the gap between the two roller bodies 3 is adjusted to meet different production and processing requirements; during the operation of the roller body 3, the connecting disks 4 at both ends of the roller body 3 are driven to rotate by external force; when the connecting disk 4 rotates, the roller 62 located on the inner side of the detection groove 41 is always in contact with the connecting disk 4. Under normal circumstances, the pressure exerted on the four rollers 62 is roughly equal. If the structure at both ends of the roller body 3 is worn, the roller body 3 as a whole will be offset and affect the parallelism. At this time, the four rollers 62 located on the outside of the connecting disk 4 will be subjected to different pressures, and then the wear of the structure at both ends of the roller body 3 can be judged by the detection results of the annular pressure sensor 66, so as to timely discover problems in the processing process and shut down for maintenance, thereby reducing the impact of changes in the parallelism of the roller body 3 on the processing quality of corrugated paper.

[0025] The gap-adjustable corrugated roller recorded in the embodiment of the present application also includes a connecting seat 5, which is symmetrically fixed on the top of the fixed seat 1 and the movable seat 2, and is located at both ends of the roller body 3. A visual inspection instrument 51 is fixedly provided on the outside of the connecting seat 5 for detecting the wear of the two roller bodies 3; wherein, an annular pressure sensor 66 is fixedly provided on the outside of the connecting seat 5; a visual inspection instrument 51 is fixedly provided on the outside of the connecting seat 5 through a bracket 53, and a tilting platform 52 for installing the mounting seat 64 is fixedly provided on the top of the connecting seat 5.

[0026] When the rollers 3 are in operation, wear will occur between the two rollers 3 and the corrugated paper due to long-term use, and the wear of the rollers 3 themselves cannot be detected by the detection component 6. At this time, the visual inspection device 51 on the outside of the connecting seat 5 collects images at the ends of the two rollers 3, and uses machine recognition technology to detect the wear of the rollers 3 themselves and the meshing condition between the two rollers 3 to ensure the processing quality of the corrugated roller.

[0027] Both ends of the roller body 3 are fixedly connected to the first spur gear 31 through the connecting disk 4; specifically, a truncated cone 32 is fixedly provided at both ends of the roller body 3, and a first positioning groove 42 is provided on the side of the connecting disk 4 close to the roller body 3 corresponding to the truncated cone 32. The connecting disk 4 is fixedly installed with both ends of the roller body 3 through a second connecting member 43, and the second connecting member 43 is a bolt. A conical positioning block 44 and a third connecting member 45 are fixedly provided on the side of the connecting disk 4 away from the roller body 3. A first positioning hole 311 is provided on the inner side of the first spur gear 31 corresponding to the conical positioning block 44. The first spur gear 31 is installed on the outer side of the connecting disk 4 through the third connecting member 45, and the third connecting member 45 is a bolt. A support base 55 is fixed on the top of the connecting base 5 through a support plate 54. A support gear 56 is symmetrically rotated on one side of the support base 55 close to the first straight gear 31, which is used to support and drive the first straight gear 31 to rotate. The two symmetrically arranged support gears 56 are driven by external force to rotate synchronously.

[0028] The first straight gear 31 is supported by the two supporting gears 56 at the bottom, and the force at both ends of the roller body 3 is shared by the two supporting gears 56. While ensuring the stability of the roller body 3, it is also convenient to disassemble and install the roller body 3 from the top. When disassembling and assembling the roller body 3 below, it is only necessary to drive the moving seat 2 upward through the hydraulic push rod 18, thereby driving the upper roller body 3 away; wherein, the hydraulic push rod 18 is fixedly set at the top of the connecting seat 5, and the driving end of the hydraulic push rod 18 is fixedly set at the bottom of the moving seat 2.

[0029] The gap-adjustable corrugated roller in the above example also includes a hydraulic cylinder 9, which is fixedly arranged on the top of the support seat 55. A positioning head 91 is fixedly arranged on the driving end of the hydraulic cylinder 9. The positioning head 91 is coaxially arranged with the first straight gear 31, and a second positioning hole 312 is provided on the inner side of the first straight gear 31 corresponding to the positioning head 91; wherein, the support gear 56 is rotatably arranged on the outer side of the support seat 55 through a force bearing 573, and the force bearing 573 is located on the inner side of the support seat 55 and the bearing sleeve 510, and a bearing groove 511 is provided on the inner side of the support seat 55 and the bearing sleeve 510 corresponding to the force bearing 573, and the bearing sleeve 510 is detachably arranged on both sides of the support seat 55.

[0030] When installing the roller body 3, the hydraulic cylinder 9 on the top of the connecting seat 5 drives the positioning head 91 to approach the roller body 3, so that the positioning head 91 cooperates with the second positioning hole 312 to realize coaxial support of the roller body 3, and then the support gear 56 is installed on the outside of the support seat 55, so that the support gear 56 is engaged with the first straight gear 31. During installation and disassembly, the support gear 56 and the support seat 55 can be assembled by fixing and disassembling the bearing sleeve 510, and the force bearing 573 cooperates with the support seat 55 and the bearing groove 511 on the inner side of the bearing sleeve 510 to realize the rotational assembly of the support gear 56, and the support gear 56 and the force bearing 573 are both used as wear parts at both ends of the roller body 3 to facilitate subsequent disassembly and maintenance.

[0031] The corrugated roller also includes two groups of lubrication assemblies 7 for lubricating the first spur gear 31 and the support gear 56. Each group of lubrication assemblies 7 includes two second spur gears 71. The two second spur gears 71 are respectively meshed and arranged at the top of the two first spur gears 31 on the same side. Second wheel seats 72 are rotatably arranged on the outside of the second spur gears 71. The second wheel seats 72 are slidably arranged on the outside of the upper support seat 55. Second elastic members 73 are fixedly arranged on the top of the second wheel seats 72 for pressing the second spur gears 71 against the top of the corresponding first spur gear 31; the shaft ends of the two second spur gears 71 are each provided with an electric valve 74, which is fixedly connected to the corresponding second wheel seat 72. The output end of the electric valve 74 is connected to the inside of the corresponding second spur gear 71, and an oil outlet hole 711 is opened on the inner side of the second spur gear 71 corresponding to the non-working tooth surface; specifically, the two electric valves 74 are connected through a hose 75, one of the electric valves 74 is connected to the external oil supply system, and the hose 75 is arranged inside the upper support seat 55.

[0032] In order to facilitate the lubrication of wear parts such as the first spur gear 31 and the support gear 56 to ensure their service life, when the first spur gear 31 drives the roller body 3 to rotate, the first spur gear 31 also drives the second spur gear 71 on the top to rotate. At this time, if the second spur gear 71 is connected to the external oil supply system through the electric valve 74, the lubricating oil will enter the interior of the second spur gear 71 through the electric valve 74, and finally contact the surface of the corresponding first spur gear 31 through the oil outlet 711 on the outside of the second spur gear 71, and then indirectly lubricate the support gear 56 through the first spur gear 31, and then realize automatic lubrication through rotation, which is convenient for maintenance during use and has low loss during the lubrication process.

[0033] The lubrication assembly 7 also includes a core column 78, which is fixedly connected to the output end of the electric valve 74. The core column 78 is rotatably arranged inside the second spur gear 71. An oil chamber 781 is provided inside the core column 78. An impeller 79 is rotatably arranged inside the oil chamber 781. The impeller 79 is driven to rotate by the second spur gear 71, and an opening is provided at the bottom of the oil chamber 781.

[0034] In order to prevent the lubricating oil inside the second spur gear 71 from being thrown out during high-speed rotation, a core column 78 is provided for rotation inside the second spur gear 71, and an oil chamber 781 connected to the output end of the electric valve 74 is provided at the bottom of the core column 78. After the lubricating oil enters the oil chamber 781, the third spur gear 712 inside is driven to rotate under the action of the second spur gear 71, so that the third spur gear 712 drives the fourth spur gear 791 to rotate, so that the fourth spur gear 791 drives the impeller 79 to rotate inside the oil chamber 781, and then the lubricating oil inside the oil chamber 781 is squeezed out through the oil outlet 711 at the bottom, and the lubricating oil is evenly applied to the outside as the first spur gear 31 rotates. When it contacts the support gear 56, since the support gear 56 is located at the bottom of the first spur gear 31, the excess lubricating oil can flow to the outside of the support gear 56 for lubrication, thereby achieving the effect of lubricating the first spur gear 31 and the support gear 56 at the same time.

[0035] A fixing plate 512 is fixedly provided on the top of the second elastic member 73 located at the bottom, and the fixing plate 512 is fixedly provided on the outside of the support seat 55. The second elastic member 73 located at the top is pressed against the second spur gear 71 by the pressure of the clamping assembly 8; the clamping assembly 8 includes a pressing plate 81, and a second slide bar 76 is slidingly provided on the inner side of the pressing plate 81.

The screw 82 is rotatably provided on the top of the support seat 55, and a rotating wheel 83 is fixed on the top of the screw 82.

[0036] During actual use, the first spur gear 31 located at the bottom is subjected to the pressure of the upper roller body 3 and the corrugated paper to maintain stable meshing transmission with the support gear 56, while the first spur gear 31 located at the top needs to rotate the rotating wheel 83 to drive the pressure plate 81 outside the screw 82 to move downward, so that the pressure plate 81 presses the second wheel seat 72 through the second elastic member 73, and then the second spur gear 71 presses the first spur gear 31 above to ensure the stability of the upper roller body 3 during operation, and the second spur gear 71 located at the bottom can be abutted against the top of the first spur gear 31 under the action of the second elastic member 73, and the expansion and contraction amount and elastic force of the second elastic member 73 meet the clearance requirements required by the two roller bodies 3.

[0037] A connecting shaft 561 is fixedly provided at the end of the support gear 56, and the connecting shaft 561 is detachably provided on the inner side of the force bearing 573. An extension ring 565 is embedded on the side of the support gear 56 close to the force bearing 573. Oil guide holes are distributed in a circular array inside the extension ring 565. The oil guide holes inside the extension ring 565 are located between the inner and outer rings of the force bearing 573 and are used to guide the lubricating oil to the inside of the force bearing 573. An oil port connected to the oil guide hole is provided at the tooth root of the support gear 56. The extension ring 565 is made of a flexible sealing material, such as rubber.

[0038] Specifically, a conical surface 562 is provided between the connecting shaft 561 and the supporting gear 56. The conical surface 562 cooperates with the mounting sleeve 571 on the inner side of the force bearing 573. A second positioning groove 572 is provided on the inner side of the mounting sleeve 571 corresponding to the conical surface 562, thereby realizing coaxial installation of the supporting gear 56 and the force bearing 573.

[0039] When the lubricating oil gathers on the surface of the supporting gear 56, the excess lubricating oil will enter the interior of the extension ring 565 through the oil port opened at the root of the tooth, and enter the interior of the force bearing 573 through the oil guide hole inside the extension ring 565 to realize the lubrication function, so as to lubricate and maintain the force bearing 573.

[0040] The outer side of the third bevel gear 59 is fixed with a plurality of springs 571, and the springs 571 are connected to the drive shaft 561 through the support frame 574. The springs 571 are connected to the support frame 574 through the support frame 575. The springs 571 are connected to the drive shaft 561 through the support frame 575.

[0041] The drive shaft 12 is rotatably arranged on both sides of the fixed base 1, and a first bevel gear 13 is arranged on the outside of the drive shaft 12.

[0042] Specifically, a base 19 is fixedly provided at the bottom of the fixed seat 1, and vertical plates 110 are fixedly provided on both sides of the base 19. The top of the vertical plate 110 is rotatably connected to the drive shaft 12. A transmission box 16 is fixedly provided at the bottom of the base 19. The two drive shafts 12 are synchronously linked through the transmission box 16. One of the drive shafts 12 is linked to the driving end of the motor 17, and the motor 17 is fixedly provided at the bottom of the base 19; a first bevel gear 13 is rotatably provided on the outside of the drive shaft 12, and a shaft sleeve 14 is fixedly provided on the top of the first bevel gear 13. The shaft sleeve 14 is fixedly connected to the drive shaft 12 through a first connecting member 15 on the outside, and the first connecting member 15 is a bolt.

[0043] By starting the motor 17 to drive one of the drive shafts 12, the drive shaft 12 drives the other drive shaft 12 to rotate synchronously through the transmission box 16. The drive shafts 12 on both sides synchronously drive the first bevel gear 13 and the second bevel gear 22 on the outside to rotate, so that the first bevel gear 13 and the second bevel gear 22 respectively drive the third bevel gear 59 on the outside to rotate. The third bevel gear 59 drives the two outer transmission gears 57 to rotate through the intermediate gear 58, so that the transmission gear 57 drives the support gear 56 to drive the first straight gear 31 to rotate, thereby realizing the synchronous start and stop of the two rollers 3. When the hydraulic push rod 18 drives the fixed seat 1 to rise and fall, it can drive the second bevel gear 22 on the outer side of the second side plate 21 to slide longitudinally along the drive shaft 12; when adjusting the meshing degree of the two rollers 3, the first connecting member 15 is used to release the fixation of the sleeve 14 and the drive shaft 12, so that the lower roller 3 can be rotated separately, so that the meshing degree of the two rollers 3 can be adjusted by rotating one of the rollers 3, and finally the sleeve 14 and the drive shaft 12 can be fixed through the first connecting member 15.

[0044] Principles and advantages of gap-adjustable corrugated rollers: First, start the motor 17 at the bottom of the base 19 to run, so that the motor 17 synchronously drives the driving shafts 12 on both sides to rotate, and the driving shafts 12 on both sides synchronously drive the first bevel gear 13 and the second bevel gear 22 on the outer side to rotate, so that the first bevel gear 13 and the second bevel gear 22 respectively drive the third bevel gear 59 on the outer side to rotate, and the third bevel gear 59 drives the two outer transmission gears 57 to rotate through the intermediate gear 58, so that the transmission gear 57 drives the supporting gear 56 to drive the first straight gear 31 to rotate, thereby realizing the synchronous start and stop of the two rollers 3. When adjusting the gap between the rollers 3, the hydraulic push rod 18 on the top of the fixed seat 1 drives the movable seat 2 to move up and down, so that the movable seat 2 drives the upper roller 3 to move up and down, so that the gap between the two rollers 3 is adjusted to meet different production and processing requirements. During the adjustment process, the movable seat 2 drives the second bevel gear 22 on the outer side of the second side plate 21 to slide longitudinally along the driving shaft 12, so that the upper roller 3 always maintains linkage with the driving shaft 12; During the operation of the roller body 3, the first spur gears 31 at both ends of the roller body 3 drive the roller body 3 to rotate through the connecting disk 4. When the connecting disk 4 rotates, the roller 62 located on the inner side of the detection groove 41 is always in contact with the connecting disk 4. If the structures at both ends of the roller body 3 are worn, the roller body 3 as a whole will be offset and the parallelism will be affected. At this time, the four rollers 62 located on the outside of the connecting disk 4 will be subjected to different pressures, and then the wear of the structures at both ends of the roller body 3 will be judged through the detection structure of the annular pressure sensor 66. At the same time, long-term use will also cause wear between the two roller bodies 3 and the corrugated paper, and the wear of the roller body 3 itself cannot be detected by the detection component 6. At this time, the visual inspection instrument 51 on the outside of the connecting seat 5 is used to collect images at the ends of the two roller bodies 3, and the wear of the roller body 3 itself and the meshing condition between the two roller bodies 3 are detected with the help of machine recognition technology, so as to timely discover problems during the processing and shut down for maintenance.

[0045] Its advantages are that the wear of the end structures of the two rollers 3 can be detected by setting up a detection component 6, so that problems can be discovered in time during the processing and the machine can be shut down for maintenance, thereby reducing the impact of changes in the parallelism of the rollers 3 on the processing quality of corrugated paper; by setting up a visual inspection instrument 51 at the ends of the two rollers 3, the visual inspection instrument 51 collects images at the ends of the two rollers 3, and uses machine recognition technology to detect the wear of the rollers 3 themselves and the meshing condition between the two rollers 3, so as to ensure the processing quality of the corrugated roller.

[0046] When the lubrication assembly 7 in the gap-adjustable corrugated roller of the present application is in operation, the second spur gear 71 located above is vertically pressed against the upper roller body 3 by the action of the pressing assembly 8 to ensure that the roller body 3 is stably meshed with the supporting gear 56 on the outside. When lubricating the first spur gear 31, the supporting gear 56 and the force bearing 573, the second spur gear 71 is connected to the external oil supply system through the electric valve 74, and the lubricating oil enters the interior of the core column 78 through the electric valve 74. The core column 78 blocks the inside of the second spur gear 71 and only opens an oil chamber 781 at the bottom for accommodating the lubricating oil. At this time, the third spur gear 712 inside is driven to rotate by the second spur gear 712, so that the third spur gear 712 drives the fourth spur gear 791 to rotate, so that the fourth spur gear 791 drives the impeller 79 to rotate inside the oil chamber 781, and then the lubricating oil inside the oil chamber 781 is squeezed out through the oil outlet 711 at the bottom. And as the first spur gear 31 rotates, the lubricating oil is evenly applied to the outside. When it contacts the supporting gear 56, since the supporting gear 56 is located at the bottom of the first spur gear 31, the excess lubricating oil can flow to the outside of the supporting gear 56 for lubrication. After the lubricating oil gathers on the surface of the supporting gear 56, the excess lubricating oil will enter the interior of the extension ring 565 through the oil port opened at the root of the support gear 56, and enter the interior of the force bearing 573 through the oil guide hole inside the extension ring 565 to realize the lubrication function, so as to lubricate and maintain the force bearing 573. Finally, the electric valve 74 is controlled to be closed to stop the lubrication work.

[0047] It is worth mentioning that the above lubrication method has the following advantages: Advantage 1: the second spur gear 71 is driven by the first spur gear 31 to rotate, so that the lubricating oil inside the second spur gear 71 is smeared on the outside of the first spur gear 31 during the rotation process, making the smearing more uniform and realizing lubrication maintenance without stopping the machine.

[0048] Advantage 2: In order to prevent the second spur gear 71 from throwing out the internal lubricating oil when rotating, a core column 78 is arranged to rotate inside the second spur gear 71 to block the inner side of the second spur gear 71, and only an oil chamber 781 is opened at the bottom to accommodate the lubricating oil. An opening is provided at the bottom of the oil chamber 781, so that the lubricating oil can only flow out through the oil outlet 711 at the bottom to prevent splashing.

[0049] Advantage three: in order to ensure the smooth outflow of the lubricating oil, the impeller 79 inside the oil chamber 781 is synchronously driven to rotate through the second spur gear 71, so that the impeller 79 uses centrifugal force to smoothly squeeze out the lubricating oil inside the oil chamber 781 through the oil outlet 711 at the bottom, and then the electric valve 74 is closed or the rotation of the first spur gear 31 is stopped to immediately stop the lubrication work, which is more convenient to operate.

[0050] Advantage four: the second spur gear 71 located above plays an oil-guiding and lubricating role during lubrication operation; when lubrication is not required, the second spur gear 71 always presses the upper roller body 3 under the action of the clamping assembly 8 to ensure the stable operation of the upper roller body 3.

[0051] Advantage five: by embedding an extension ring 565 on one side of the support gear 56, the sealing between the support gear 56 and the force bearing 573 is ensured, so that the extension ring 565 can guide the lubricating oil collected on the surface of the support gear 56 into the interior of the force bearing 573 for further lubrication, so that the first spur gear 31, the support gear 56 and the force bearing 573 as the load-bearing components can be lubricated and maintained at any time to ensure their service life.

[0052] Advantage six: by setting two supporting gears 56 to support the first straight gear 31, while ensuring the stability of the end of the roller body 3, since the supporting gear 56 is located on the lower outer side of the first straight gear 31, it can receive the lubricating oil on the surface of the first straight gear 31 to lubricate itself, and it is convenient to install and disassemble the roller body 3.
