Description

Technical Field

[0001] This utility model relates to the field of special paper processing technology, specifically a rewetting line pressure roller lifting device for processing special paper. Background Technology

[0002] Specialty paper is paper made from different fibers using a paper machine to produce paper with special functions. It has special uses, is produced in relatively small quantities, and comes in a wide variety of types. It is a general term for various special purpose papers or art papers. In the production process of specialty paper, after coating, printing or drying, it often needs to undergo rewetting treatment. During the rewetting treatment process, a pressure roller lifting device is required.

[0003] For example, Chinese patent application CN201620564557.2 describes a lifting device for a re-wetting line pressure roller used in processing specialty paper. This device includes a frame, a guide rail assembly, a slider, a pressure roller, a cylinder base, and a cylinder. The guide rail assembly is connected to the inner side of the frame, and the guide rail assembly engages with the slider. The slider is connected to the shaft end of the pressure roller via a bearing sleeve. The top of the guide rail assembly is connected to the cylinder base, which is connected to the cylinder. The telescopic rod of the cylinder is connected to the screw hole of the slider. This device is arranged in a symmetrical left-right structure. It features a simple structure, reasonable design, and novel concept. It uses a cylinder to suspend the pressure roller, achieving lifting and lowering of the roller, controlling the running position of the specialty paper, ensuring coating quality, and using the guide rail and slider for positioning to avoid horizontal and tilting displacement of the pressure roller. This promotes uniformity of coating amount during the coating process, improves product quality, and saves production costs.

[0004] However, in actual use, after the device is used to raise and lower the pressure roller, the overall height of the device is fixed, which makes it difficult to retract. When it needs to be moved later, it occupies a relatively large space and is not convenient for other operations and processing, thus limiting its use. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a lifting device for the rewind line pressure rollers used in processing specialty paper. By adjusting the angle between several inclined rods, it achieves retractable lifting and lowering. While ensuring the reliability of the pressure roller lifting function, it maximizes the saving of equipment space and significantly improves the convenience and safety of maintenance operations, thereby optimizing the production line layout and improving the overall performance of the equipment. It can effectively solve the problems in the background technology.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a lifting device for a rewetting line pressure roller for processing special paper, comprising two opposing support seats, each of the two support seats having a top seat on its top, and the pressure roller being disposed between the two top seats;

[0007] A lifting assembly is provided between the bottom of the top seat and the top of the support seat to drive the pressure roller to rise and fall, while also facilitating overall retraction;

[0008] A scraper assembly is provided at one end of the outer wall of the pressure roller to remove moisture from the surface of the pressure roller;

[0009] The lifting assembly includes a threaded rod. The front top of the support base and the rear bottom of the top base are both provided with slots. The front and rear ends of the threaded rod are connected to the front and rear sides inside the bottom slot through bearings. Threaded blocks are connected to the threaded rod by threads. Several intersecting and vertically distributed diagonal bars are provided between the support base and the top base.

[0010] Preferably, the center and both ends of the opposite inclined rod are rotatably connected by a rotating rod, and the same limiting rod is fixedly provided between the front and rear ends inside the top slot. A slider is slidably provided on the limiting rod to facilitate the slider to move horizontally along the limiting rod.

[0011] Preferably, the top ends of the two top inclined rods and the bottom ends of the two bottom inclined rods are rotatably provided with hinge seats. The hinge seat on the front side of the bottom is fixedly provided on the top of the threaded block, the hinge seat on the rear side of the bottom is fixedly provided on the rear side of the top of the support seat, the hinge seat on the front side of the top is fixedly provided on the front side of the bottom of the top seat, and the hinge seat on the rear side of the top is fixedly provided on the bottom of the slider. This facilitates the horizontal movement of the hinge seat on the front side of the bottom along the threaded block and the horizontal movement of the hinge seat on the rear side of the top along the slider, thereby adjusting the included angle between adjacent inclined rods.

[0012] Preferably, a crank handle is connected to the front side of the support base via a bearing. The rear end of the crank handle passes through the front side of the support base and is fixedly connected to the front end of the threaded rod. A bolt for fixing the support base and the crank handle is threadedly connected to the crank handle, which makes it easy to unscrew the bolt and turn the crank handle to drive the threaded rod to rotate.

[0013] Preferably, a U-shaped bracket is fixedly provided at the center between the tops of the two top seats, and the two top seats are connected to the same rotating shaft by a bearing on the side that is close to each other. The pressure roller is fixedly installed on the rotating shaft, and a motor is fixedly provided inside one side of the top seat. The output shaft of the motor is fixedly connected to one end of the rotating shaft, so as to facilitate driving the rotating shaft to drive the pressure roller to rotate.

[0014] Preferably, the wiper assembly includes a wiper frame, which is slidably disposed on the outer wall of the pressure roller. A T-shaped slider is fixedly disposed at the top center of the wiper frame. A T-shaped groove is opened at the top of the U-shaped bracket. The T-shaped slider is slidably disposed inside the T-shaped groove, so that the T-shaped slider can slide horizontally along the T-shaped groove and limit the movement of the wiper frame.

[0015] Preferably, water collection grooves are provided on both sides of the inside of the wiper frame, and two horizontally distributed drain pipes are fixedly provided at the bottom of the wiper frame. The two drain pipes are respectively connected to the inside of the two water collection grooves.

[0016] Compared with the prior art, this utility model provides a lifting device for the rewetting line pressure roller of special paper processing, which has the following beneficial effects:

[0017] 1. This utility model uses the horizontal movement of the threaded block to drive the top hinge seat to move. The movement of the hinge seat drives the adjacent inclined rods to rotate around the rotating rod, adjusting the included angle between the adjacent inclined rods, thereby driving the pressure roller to rise and fall. After use, the included angle between several inclined rods can be increased in the same way, causing the inclined rods to tilt and retract, thus realizing the retractable lifting and falling. While ensuring the reliability of the pressure roller lifting function, it saves the equipment space to the greatest extent and greatly improves the convenience and safety of maintenance operations, thereby optimizing the production line layout and improving the overall performance of the equipment.

[0018] 2. This utility model pushes the wiper frame to move horizontally along the pressure roller, so that when the inner wall of the wiper frame contacts the surface of the pressure roller, it can scrape the water stains left on the surface into the water collection tank, thereby removing water to reduce oxidation and corrosion on the surface of the pressure roller, protect the roller body precision, extend its service life, and ensure that the contact pressure with the paper is uniform when starting up next time, avoiding pressure fluctuations caused by water film interference, and improving processing reliability.

[0026] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0027] like Figures 1-5 As shown, this utility model provides a lifting device for a rewetting line pressure roller for processing special paper, including two opposing support seats 1. Each of the two support seats 1 is provided with a top seat 2, and the pressure roller 7 is located between the two top seats 2. A U-shaped bracket 5 is fixedly provided at the center between the tops of the two top seats 2. The two top seats 2 are connected to the same rotating shaft 6 through a bearing on their adjacent sides, and the pressure roller 7 is fixedly mounted on the rotating shaft 6. A motor is fixedly provided inside one side of the top seat 2, and the output shaft of the motor is fixedly connected to one end of the rotating shaft 6 to facilitate driving the rotating shaft 6 to drive the pressure roller 7 to rotate.

[0028] like Figures 1-3 As shown, a lifting assembly 3 is provided between the bottom of the top seat 2 and the top of the support seat 1 for driving the pressure roller 7 to rise and fall, and also for facilitating overall retraction. The lifting assembly 3 includes a threaded rod 31. A slot 4 is provided on the front side of the top of the support seat 1 and the rear side of the bottom of the top seat 2. The front and rear ends of the threaded rod 31 are connected between the front and rear sides inside the bottom slot 4 by bearings.

[0029] A threaded block 32 is threadedly connected to the threaded rod 31. Several intersecting and vertically distributed inclined rods 33 are provided between the support base 1 and the top base 2. The center and two ends of the opposite inclined rods 33 are rotatably connected by a rotating rod 34. The same limiting rod 36 is fixedly provided between the front and rear ends inside the slot 4 at the top. A slider 37 is slidably provided on the limiting rod 36 to facilitate the horizontal movement of the slider 37 along the limiting rod 36.

[0030] The top ends of the two top inclined rods 33 and the bottom ends of the two bottom inclined rods 33 are rotatably provided with hinge seats 35. The hinge seat 35 on the front side of the bottom is fixedly installed on the top of the threaded block 32, the hinge seat 35 on the rear side of the bottom is fixedly installed on the rear side of the top of the support seat 1, the hinge seat 35 on the front side of the top is fixedly installed on the front side of the bottom of the top seat 2, and the hinge seat 35 on the rear side of the top is fixedly installed on the bottom of the slider 37. This allows the hinge seat 35 on the front side of the bottom to move horizontally along the threaded block 32, and the hinge seat 35 on the rear side of the top to move horizontally along the slider 37, thereby adjusting the included angle between adjacent inclined rods 33.

[0031] The top ends of the two top inclined rods 33 and the bottom ends of the two bottom inclined rods 33 are rotatably provided with hinge seats 35. The hinge seat 35 on the front side of the bottom is fixedly installed on the top of the threaded block 32, the hinge seat 35 on the rear side of the bottom is fixedly installed on the rear side of the top of the support seat 1, the hinge seat 35 on the front side of the top is fixedly installed on the front side of the bottom of the top seat 2, and the hinge seat 35 on the rear side of the top is fixedly installed on the bottom of the slider 37. This allows the hinge seat 35 on the front side of the bottom to move horizontally along the threaded block 32, and the hinge seat 35 on the rear side of the top to move horizontally along the slider 37, thereby adjusting the included angle between adjacent inclined rods 33.

[0032] When the lifting component 3 is set up, the bolt on the crank handle 38 is unscrewed and the crank handle 38 is turned to drive the threaded rod 31 inside the slot 4 to rotate. The rotation of the threaded rod 31 drives the threaded block 32 to move horizontally along the threaded rod 31, and at the same time drives the top hinge seat 35 to move. The movement of the hinge seat 35 causes several inclined rods 33 at the top to tilt through the rotating rod 34, adjusting the included angle between adjacent inclined rods 33, so that the top of one inclined rod 33 drives the slider 37 to slide horizontally along the limiting rod 36, limiting the lifting height of several inclined rods 33, thereby driving the pressure roller 7 to rise and fall.

[0033] After use, the angle between several inclined rods 33 can be widened by driving them in the same way, so that the inclined rods 33 tilt and retract, thereby realizing the lifting and lowering when retractable. While ensuring the reliability of the lifting function of the pressure roller 7, the space occupied by the equipment is saved to the greatest extent and the convenience and safety of maintenance operations are greatly improved, thereby optimizing the production line layout and improving the overall performance of the equipment.

[0034] like Figure 1 , Figure 2 , Figure 4 , Figure 5 As shown, a wiper assembly 8 is provided at one end of the outer wall of the pressure roller 7 for removing water from the surface of the pressure roller 7. The wiper assembly 8 includes a wiper frame 81, which is slidably disposed on the outer wall of the pressure roller 7. A T-shaped slider 82 is fixedly disposed at the top center of the wiper frame 81. A T-shaped groove 9 is opened at the top of the U-shaped bracket 5. The T-shaped slider 82 is slidably disposed inside the T-shaped groove 9, which facilitates the horizontal sliding of the T-shaped slider 82 along the T-shaped groove 9 and limits the movement of the wiper frame 81. Water collection grooves 83 are opened on both sides inside the wiper frame 81. Two horizontally distributed drain pipes 84 are fixedly disposed at the bottom of the wiper frame 81, and the two drain pipes 84 are respectively connected to the interior of the two water collection grooves 83. A valve 85 is fixedly disposed on the drain pipe 84, which facilitates opening the valve 85 to drain the water inside the water collection groove 83.

[0035] By setting up the wiper assembly 8, after the pressure roller 7 has been used, water stains will adhere to the surface of the pressure roller 7. By pushing the wiper frame 81 to move horizontally along the pressure roller 7 and driving the T-shaped slider 82 to slide along the inside of the T-shaped groove 9, the movement of the wiper frame 81 is limited. When the inner wall of the wiper frame 81 contacts the surface of the pressure roller 7, it can scrape the water stains left on the surface of 77 into the water collection tank 83. Finally, by opening the valve 85, the collected wastewater is discharged through the drain pipe 84, thereby removing water to reduce oxidation and corrosion on the surface of the pressure roller 7, protect the roller body precision, extend its service life, and ensure uniform contact pressure with the paper when starting up next time, avoiding pressure fluctuations caused by water film interference and improving processing reliability.

[0036] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
