Description

Technical Field

[0001] This invention relates to the field of paper dewatering technology, specifically to a boot-type press roll for paper dewatering. Background Technology

[0002] With the rapid development of the paper industry and the high speed of paper machines, there are higher requirements for the dewatering effect of the press section. Among them, the boot press appeared in the early 1980s. This type of press belongs to high pressure press or wide pressure zone press. The higher pressing force means that it has a higher pressing specific pressure compared with flat press rolls. The wide pressure zone also means that compared with traditional press roll press, the wet paper sheet has a longer residence time in the pressure zone, resulting in better dewatering effect.

[0003] Existing boot-type pressing roller devices often require production shutdowns for replacement when the curved surface of the boot plate wears down during continuous use, resulting in poor dewatering performance. This not only wastes manpower but also consumes a significant amount of time, leading to low production efficiency, increased costs, and reduced equipment practicality and flexibility, making them extremely inconvenient to use. Therefore, in view of the above situation, there is an urgent need to develop a boot-type pressing roller device to overcome the shortcomings in current practical applications.

[0004] The current patent publication (announcement) number: CN114318927A discloses a boot-type pressing roller device, comprising a support frame and a base plate for fixing the support frame, and further comprising: a water collection box, the water collection box being rotatably connected to the support frame via a rotating shaft; a boot sleeve, the boot sleeve being connected to the water collection box; and a conversion assembly, the conversion assembly being located inside the boot sleeve; wherein, the conversion assembly includes a driving assembly and a telescopic assembly, the driving assembly including a rotating plate and a fixed plate, the rotating plate being connected to the telescopic assembly, the fixed plate being fixedly connected to the boot sleeve, and the fixed plate being slidably connected to the telescopic assembly, the two sets of telescopic assemblies respectively including a first boot plate and a second boot plate. This invention, the boot-type pressing roller device, has a novel structure, is simple to operate, saves manpower and reduces replacement time, improves production efficiency, and enhances the practicality and flexibility of the equipment, providing convenience for workers. When using this patent, after the first and second shoe plates are used, production still needs to be stopped for inspection and replacement before production can continue. Compared with traditional shoe rollers, it only increases the production duration, but it still cannot achieve the function of inspecting and replacing shoe plates without stopping production.

[0031] In this embodiment, lifting plates 37 are fixed on the opposite sides of the two sealing plates 6. A screw 38 is threadedly connected to the right side of the inside of the lifting plate 37, and a guide rod 39 is slidably connected to the left side of the inside of the lifting plate 37. The bottom ends of the two guide rods 39 are fixed to the base 40. The bottom ends of the two screws 38 are rotatably connected to the upper surface of the base 40. The height can be adjusted by rotating the two screws 38.

[0032] In this embodiment, L-grooves 44 are provided on both the left and right sides of the mounting groove 28 below the sliding groove 29. An inner cavity 45 is provided at the bottom of the shoe plate 12. A toothed cylinder 46 is rotatably connected inside the inner cavity 45. A toothed plate 47 is meshed with the bottom of the toothed cylinder 46. The end of the toothed plate 47 away from the toothed cylinder 46 extends into the L-grooves 44 and is fixed with a vertical plate 49. Abutment blocks 48 are meshed with the opposite ends of the two toothed cylinders 46. The abutment blocks 48 are located outside the toothed plate 47.

A square tube 51 is slidably connected to the outer surface of the abutment 50. A spring 52 is fixed between the square tube 51 and the abutment 50. Inside the slot 36, shaft 1 53 and shaft 2 55 are rotatably connected from the outside to the inside. The outer surfaces of shaft 1 53 and shaft 2 55 are both provided with belt 2 56. Shaft 1 53 and shaft 2 55 are connected by belt 2 56. A gear 57 is fixed behind the outer surface of shaft 2 55. A rotating frame 54 is fixed on the outer surface of shaft 1 53 outside the belt 2 56. A toothed block 58 is meshed on the top of the gear 57. The opposing ends of the toothed blocks 58 are located inside the two sliding grooves 29, and the opposing ends of the two square cylinders 51 are located inside the two slots 36. The hydraulic cylinder 10, electric push rod 13, motor 1 8, motor 2 17, camera 42, sensor 43, and motor 3 21 are all connected to external control equipment. When the mounting plate 11 is disengaged from the mounting groove 28, the internal structure of the shoe plate 12 is in a standby state. At this time, the outer surface of the square cylinder 51 is on the same plane as the inner surface of the mounting groove 28 and does not protrude, so that the mounting plate 11 can be directly inserted into the mounting groove 28 and the abutment block 4 8 will be in a protruding state, allowing the mounting plate 11 to press down; when the mounting plate 11 is installed with the new shoe plate 12, the hydraulic cylinder 10 pushes the mounting plate 11 down, and the mounting plate 11 enters the mounting groove 28 of the shoe plate 12. Its bottom presses against the abutment block 48, causing it to descend. Through the toothed cylinder 46 and toothed plate 47, the abutment rod 50 pushes the spring 52 to make the square cylinder 51 lock into the slot 36, and pushes the rotating frame 54 to rotate. Under the transmission of the belt 56 and other structures, the toothed block 58 moves into the sliding groove 29, thereby connecting the mounting plate 11 and the shoe plate 12, making them inseparable.

[0033] In this embodiment, the abutment 33 is adapted to the slot 36, and the abutment 33 can be inserted into the slot 36.

[0034] In this embodiment, a sensor 43 is embedded below the inner surface of the groove 20, and cameras 42 are fixed on both the left and right sides inside the bottom roller 2. The two cameras 42 can transmit the captured images to the external control device so that personnel can observe the degree of damage to the shoe plate 12 below. When the shoe plate 12 is placed into the groove 20, the sensor 43 is triggered and the motor 21 operates.

[0035] In this embodiment, the plate groove 20 is adapted to the shoe plate 12, and the shoe plate 12 can be placed inside the plate groove 20.

[0036] In this embodiment, the back roller 4 is connected to an external power mechanism, and the left and right ends of the paper blanket 5 are connected to an external winding mechanism. The back roller 4 rotates under the action of the external power mechanism, and the paper blanket 5 can be wound up by the external winding mechanism after being pressed.

[0037] In this embodiment, a through opening 41 is provided at the lower part of the front sealing plate 6. A baffle is rotatably connected inside the opening 41 via a hinge, and the baffle blocks the opening 41. After the boot plate 12 is inserted into the plate groove 20, the boot plate 12, the disassembly frame 19 and the opening 41 are adapted to each other. When the damaged boot plate 12 is placed in the plate groove 20, it can be lowered and then moved forward by the conveyor belt 16 and the connecting plate 18, and slide out from the opening 41 so that personnel can remove the boot plate 12 inside the plate groove 20 and place a new boot plate 12.

[0038] The working principle of this device is as follows: During use, the rotating back roller 4 drives the shoe sleeve 3 to move along the outer surface of the roller core 1 and the bottom roller 2, and the shoe plate 12 and the back roller 4 squeeze the paper blanket 5 to dehydrate it; after a certain period of use, the hydraulic cylinder 10 is controlled to retract, so that the two shoe plates 12 are retracted into the roller core 1. The motor 8 drives the support beam 9 and the shoe plate 12 to rotate half a revolution, so that the unused shoe plate 12 is on top. The hydraulic cylinder 10 pushes the shoe plate 12 to reset. The camera 42 takes pictures of the inside of the used shoe plate 12 for inspection. If the arc surface is worn beyond a certain degree, it will be replaced. The lower hydraulic cylinder... 10. The wear shoe plate 12 is pushed down and enters the groove 20. The outer surface of the shoe plate 12 is in contact with the inner surface of the groove 20. Friction wheel 25 contacts friction wheel 1 27. Sensor 43 is triggered, causing motor 3 21 to operate. Through the rotation rod 1 23, transmission wheel 25, belt 1 26, and rotation rod 24, friction wheel 1 27 rotates, which drives friction wheel 2 35 to rotate. Screw 1 31 rotates, and the screw plate 32 on its outer surface moves inward. Through the compression spring 1 34, it pushes the abutment plate 33 to move outward. The moving abutment plate 33 pushes the toothed block 58 to slide into the slot 36. After the toothed block 58 moves, gear 57 rotates. The rotating frame 54 rotates vertically via the sequential transmission of shaft 55, belt 56, and shaft 53. As the rotating frame 54 rotates, it pushes the square cylinder 51 inward. The abutment rod 50 is limited by the vertical plate 49, toothed plate 47, toothed cylinder 46, and abutment block 48. The abutment block 48, limited by the mounting plate 11, cannot move and can only compress the spring 52. At this time, the connection between the mounting plate 11 and the shoe plate 12 is released, and the hydraulic cylinder 10 operates, causing the mounting plate 11 to rise and disengage from the mounting groove 28. As the mounting plate 11 moves, the abutment block, under the influence of the spring 52, pushes the vertical plate 49, toothed plate 47, and toothed cylinder 46 inward. When the device moves downwards, the device rises and protrudes. At this time, the electric push rod 13 operates to lower the conveyor frame 14, the disassembly frame 19, and the shoe plate 12. When they fall to the position of the opening 41, they stop. The motor 17 operates, and the two conveyor rollers 15 move the conveyor belt 16. The connecting plate 18 drives the disassembly frame 19 and its internal shoe plate 12 to move forward and pass through the opening 41 to be exposed. Personnel can then pull out the shoe plate 12 and put a new shoe plate 12 into the plate groove 20. The conveyor belt 16 and other structures reverse and reset, so that the new shoe plate 12 is installed on the lower mounting plate 11, thus completing the shoe plate 12 replacement operation. No production stoppage is required, reducing personnel operation and improving work efficiency.

[0039] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present invention are also within the protection scope of the present invention.
