Description

Technical Field

[0001] This invention belongs to the field of paper repair technology, and in particular relates to a paper repair device for books. Background Technology

[0002] During long-term storage, borrowing, and handling, library books are susceptible to damage such as surface dust accumulation and creases due to factors including temperature and humidity fluctuations, external bending, and dust buildup. Dust not only affects the appearance of the documents, but impurities in the dust also accelerate paper acidification and aging. Wrinkled and curled pages not only hinder reading and scanning, but long-term deformation further exacerbates paper fiber fatigue and damage. Therefore, page dust removal and crease smoothing are fundamental steps in the protective restoration of paper documents.

[0003] Books and archives bound together can be repaired by unraveling the seams or removing the bindings, breaking them down into individual pages. However, paper repair lacks the ability to remove dust from the paper, and the dust adhering to the paper surface can affect subsequent repairs. In addition, the pages to be repaired are generally thin and have low paper fiber strength. If a rigid contact limiting structure is used, the clamping and pressing forces can easily cause squeezing damage to the pages, or even cause the paper to tear or the edges to break. On the other hand, if no effective limiting constraint is applied to the paper, the paper will shift and bulge during the repair process, thereby reducing the device's ability to smooth out paper wrinkles. Summary of the Invention

[0004] The purpose of this invention is to address the problems of existing paper repair devices that lack dust removal capabilities and whose lack of limiting mechanisms during the repair process can cause paper displacement or bulging, thus reducing the device's ability to smooth out paper wrinkles. Therefore, this invention proposes a paper repair device for books.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A book paper repair device includes a base frame and a metal platform slidably connected inside the base frame. The upper surface of the metal platform is evenly provided with several through holes. A heating wire is embedded inside the metal platform. A first motor is fixedly connected to the inner wall of the base frame. An eccentric wheel fixedly connected to the output end of the first motor abuts against the bottom surface of the metal platform. A piston rod is slidably connected to the inner wall of a piston cylinder embedded in the bottom wall of the base frame. The upper end of the piston rod is fixedly connected to the bottom surface of the metal platform, and a telescopic spring provided on the bottom surface of the piston rod is fixedly connected to the inner bottom wall of the piston cylinder. A fan is fixedly connected to the bottom surface of the base frame. A smoothing mechanism is provided above the metal platform. The smoothing mechanism includes an electric steering platform. A straight rod is provided inside a slide plate fixedly connected to the bottom surface of the electric steering platform. The output end of a second motor fixedly connected to the outer surface of the slide plate is fixedly connected to the straight rod. A pair of reciprocating threads on the outer surface of the straight rod are engaged with a first nut. A smoothing rod is provided outside each of the two first nuts.

[0006] As a further description of the above technical solution: The second motor passes through the slide plate and is fixedly connected to the left end of the straight rod, and the second motor is rotatably connected to the passage of the slide plate. The right end of the straight rod is rotatably connected to the inner wall of the slide plate.

[0007] As a further description of the above technical solution: A vertical cylinder is fixedly connected to the outer surface of the first nut. A vertical rod and a smoothing rod are rotatably connected to the inner wall of the vertical cylinder. A compression spring is fixedly connected to the upper end of the vertical rod and is fixedly connected to the inner top wall of the vertical cylinder.

[0008] As a further description of the above technical solution: The ball bearings rotatably connected to the bottom surface of the metal platform abut against the eccentric wheel. The upper and lower ends of the telescopic spring are fixedly connected to the piston rod and the piston cylinder, respectively. The upper end of the piston rod is slidably connected to the through-hole of the piston cylinder.

[0009] As a further description of the above technical solution: The exhaust fan is fixedly connected to the middle of the bottom surface of the base frame, and the air inlet of the exhaust fan is connected to the inside of the base frame, while the air outlet of the exhaust fan is connected to the outside.

[0010] As a further description of the above technical solution: The pair of brackets fixedly connected to the upper surface of the bottom frame are each equipped with a top box. The inner walls of the two top boxes are respectively rotatably connected to a first threaded rod and a limiting rod. The outer surface of the first threaded rod is threaded with a second nut. The outer surface of the limiting rod is slidably connected with a limiting ring. The third motor fixedly connected to the outer surface of the top box is fixedly connected to the front end of the first threaded rod.

[0011] As a further description of the above technical solution: The top frame above the electric steering platform is fixedly connected to the outer surface of the second nut and the limiting ring. The second threaded rod inside the top frame is threadedly connected to the third nut. The telescopic end of the electric telescopic rod fixedly connected to the outer surface of the third nut is fixedly connected to the electric steering platform. The fourth motor fixedly connected to the outer surface of the top frame is fixedly connected to the right end of the second threaded rod.

[0012] As a further description of the above technical solution: The third motor is rotatably connected to the top box and the fourth motor is rotatably connected to the top frame. The left end of the second threaded rod is rotatably connected to the inner wall of the top frame.

[0013] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are: In this invention, the paper to be repaired is unstitched or its binding removed and laid flat on the upper surface of a metal platform. The operation of the exhaust fan generates negative pressure, which the device uses to adsorb and limit the paper to be repaired. The first motor drives the eccentric wheel to rotate, causing the metal platform to vibrate the paper. This vibration disturbs the dust and paper scraps attached to the paper surface, thus achieving a dust removal effect and reducing the impact of dust on subsequent paper repair. At the same time, the negative pressure adsorption keeps the paper flat and constrained on the surface of the metal platform, reducing paper displacement and bulging during the process. The low-temperature heating of the heating wire promotes the release of residual stress in the paper fibers. Combined with the flattening constraint provided by the negative pressure and the second motor driving two smoothing rods to move in opposite directions or towards each other, the smoothing effect on paper wrinkles and curling deformation is increased.

[0016] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0017] Please see Figure 1-6 This invention provides a technical solution: a book paper repair device, including a base frame 1 and a metal platform 2 slidably connected inside the base frame 1. The upper surface of the metal platform 2 has several through holes 3 evenly distributed. A heating wire 4 is embedded inside the metal platform 2. A first motor 5 is fixedly connected to the inner wall of the base frame 1. An eccentric wheel 6 fixedly connected to the output end of the first motor 5 abuts against the bottom surface of the metal platform 2. A ball bearing 23 rotatably connected to the bottom surface of the metal platform 2 abuts against the eccentric wheel 6. The ball bearing 23 reduces wear between the eccentric wheel 6 and the bottom surface of the metal platform 2, extending the service life of the device. A piston rod 8 is slidably connected to the inner wall of a piston cylinder 7 embedded in the inner bottom wall of the base frame 1. The upper end of the piston rod 8 is fixedly connected to the bottom surface of the metal platform 2, and a telescopic spring 9 on the bottom surface of the piston rod 8 is fixedly connected to the inner bottom wall of the piston cylinder 7. The upper and lower ends of the telescopic spring 9 are fixedly connected to the piston rod 8 and the piston cylinder 7, respectively. Figure 1 and Figure 4 The telescopic springs 9 are all in their natural state. The telescopic springs 9 are set to provide a reset effect for the metal platform 2. The upper end of the piston rod 8 is slidably connected to the through-hole of the piston cylinder 7 to prevent friction between the piston rod 8 and the through-hole of the piston cylinder 7. The bottom surface of the bottom frame 1 is fixedly connected to the exhaust fan 10. The exhaust fan 10 is fixedly connected to the middle of the bottom surface of the bottom frame 1, and the air inlet of the exhaust fan 10 is connected to the inside of the bottom frame 1. The air outlet of the exhaust fan 10 is connected to the outside. The exhaust fan 10 sets a negative pressure adsorption effect on the paper placed on the upper surface of the metal platform 2, which slows down the paper displacement and bulging during the processing.

[0018] The heating wire 4 is arranged in an S-shape inside the metal platform 2, which is conducive to uniform heating of the paper. It is used for low-temperature heating to smooth out the wrinkles of the book paper. Its suitable working temperature range is set to 40℃ to 65℃. This temperature range can promote the slow release of residual stress inside the paper fibers under negative pressure adsorption constraint, and minimize thermal damage to old pages. If the heating temperature exceeds this range, especially if the temperature continues to be higher than 70℃, it will accelerate the thermal degradation reaction of paper cellulose and hemicellulose, causing acidified pages to become more brittle, yellow and discolored, reducing the mechanical strength of the paper. It can also easily cause printing ink and handwriting to bleed, spread, fade and peel off. Excessive temperature can also cause the paper to produce new wavy warping deformation. Even if it is cooled later, this type of deformation is difficult to recover. In severe cases, it can cause irreversible permanent damage to the pages of the collection that need to be restored.

[0019] A smoothing mechanism 11 is installed above the metal platform 2. A pair of supports 24 fixedly connected to the upper surface of the base frame 1 each have a top box 25. The top box 25 is fixedly connected to the top of the supports 24. A first threaded rod 26 and a limiting rod 27 are rotatably connected to the inner walls of the two top boxes 25, respectively. A second nut 28 is threaded onto the outer surface of the first threaded rod 26, and a limiting ring 29 is slidably connected to the outer surface of the limiting rod 27. A third motor 30 is fixedly connected to the outer surface of the top box 25 and to the front end of the first threaded rod 26. The output end of the third motor 30 is rotatably connected to the through-hole of the top box 25. The operation of the third motor 30 drives the first threaded rod 26 to rotate, allowing the second nut 28 to drive the smoothing mechanism 11 to move back and forth. A top frame 31 is installed above the electric steering platform 12, and the second nut 28 and... The outer surface of the limiting ring 29 is fixedly connected. The second threaded rod 32 inside the top frame 31 is threadedly connected to the third nut 33. The left end of the second threaded rod 32 is rotatably connected to the inner wall of the top frame 31. The telescopic end of the electric telescopic rod 34, which is fixedly connected to the outer surface of the third nut 33, is fixedly connected to the electric steering platform 12. The telescopic movement of the electric telescopic rod 34 can drive the smoothing mechanism 11 to move up and down. The fourth motor 35, which is fixedly connected to the outer surface of the top frame 31, is fixedly connected to the right end of the second threaded rod 32. The output end of the third motor 30 is rotatably connected to the passage of the top box 25, and the output end of the fourth motor 35 is rotatably connected to the passage of the top frame 31. The operation of the fourth motor 35 can drive the second threaded rod 32 to rotate, thereby causing the third nut 33 to drive the electric telescopic rod 34 and the smoothing mechanism 11 to move left and right.

[0020] The smoothing mechanism 11 includes an electric steering table 12, also known as an electric rotary table. This is an electromechanical rotating component capable of automatic angle adjustment. It mainly consists of a base, a rotary table surface, support bearings, a drive motor, a reduction transmission mechanism, and an angle encoder. During operation, the control system outputs control signals, and the drive motor outputs power. This power is reduced in speed and increased in torque by the reducer before being transmitted to the rotary table surface. The support bearings bear the axial and radial loads of the table surface and the negative pressure working plate above, ensuring smooth and stable rotation. The encoder collects the actual rotation angle signal of the rotary table surface in real time and feeds it back to the control system to form a closed-loop control, thereby precisely controlling the rotation angle, direction, and speed. Once the preset position is reached, it can be locked in place. The electric steering table 12 is existing technology and will not be described in detail in this application. The bottom surface of the electric steering table 12 is fixedly connected to… A straight rod 16 is provided inside the slide plate 13. The output end of a second motor 14, which is fixedly connected to the outer surface of the slide plate 13, is fixedly connected to the straight rod 16. The second motor 14 passes through the slide plate 13 and is fixedly connected to the left end of the straight rod 16. The second motor 14 is rotatably connected to the through-hole of the slide plate 13 to prevent friction between the second motor 14 and the through-hole of the slide plate 13. The right end of the straight rod 16 is rotatably connected to the inner wall of the slide plate 13. A pair of reciprocating threads 17 on the outer surface of the straight rod 16 are each engaged with a first nut 18. A smoothing rod 19 is provided on the outside of each of the two first nuts 18. A vertical cylinder 20 is fixedly connected to the outer surface of the first nut 18. A vertical rod 21, which is slidably connected to the inner wall of the vertical cylinder 20, is rotatably connected to the smoothing rod 19. A compression spring 22, which is fixedly connected to the upper end of the vertical rod 21, is fixedly connected to the inner top wall of the vertical cylinder 20. Figure 1 and Figure 5 The compression springs 22 are all in their natural state. The combination of the vertical cylinder 20, the vertical rod 21 and the compression springs 22 provides a buffering effect for the contact between the smoothing rod 19 and the paper. The operation of the second motor 14 can drive the two first nuts 18 to move towards or away from each other, thereby enabling the smoothing rod 19 to smooth the paper in contact and reduce wrinkles.

[0021] The paper in the book to be repaired is unstitched or its binding removed and laid flat on the upper surface of the metal platform 2. The operation of the exhaust fan 10 generates negative pressure, which adsorbs the paper on the upper surface of the metal platform 2. The low-temperature heating of the heating wire 4 is beneficial for smoothing and shaping. For stubborn wrinkles, the paper can be slightly moistened in advance to allow the paper fibers to stretch. Under the subsequent negative pressure, low-temperature heating and smoothing effect, the smoothing effect of the paper wrinkles is improved. The operation of the third motor 30 and the fourth motor 35 drives the smoothing mechanism 11 to move back and forth and left and right. The extension of the electric telescopic rod 34 brings the smoothing rod 19 into contact with the paper. The operation of the second motor 14 drives the two smoothing rods 19. Moving in opposite directions or towards each other, the device smooths out the wrinkles in the paper. It uses negative pressure to adsorb and limit the paper to be repaired. The first motor 5 drives the eccentric wheel 6 to rotate, causing the metal platform 2 to vibrate the paper. This vibration disturbs the dust and paper scraps attached to the paper surface, thus achieving a dust removal effect. At the same time, the negative pressure adsorption keeps the paper flat and constrained on the surface of the metal platform 2, reducing paper displacement and bulging during the process. The low-temperature heating of the heating wire 4 promotes the release of residual stress in the paper fibers. Combined with the flattening constraint provided by the negative pressure and the movement of the smoothing rod 19, the smoothing effect on paper wrinkles and curling deformation is increased.

[0022] Working principle: In use, connect the first motor 5, exhaust fan 10, second motor 14, third motor 30, and fourth motor 35 to the power supply. Remove the stitching or binding of the book to be repaired and lay it flat on the upper surface of the metal platform 2. The exhaust fan 10 generates negative pressure, which adsorbs the paper on the upper surface of the metal platform 2. The operation of the third motor 30 and the fourth motor 35 drives the smoothing mechanism 11 to move back, forth, left, and right. The extension of the electric telescopic rod 34 brings the smoothing rod 19 into contact with the paper. The operation of the second motor 14 drives the two smoothing rods 19 to move in opposite directions or towards each other, smoothing the wrinkles in the paper. The device achieves a smoothing effect by using negative pressure to adsorb and limit the paper to be repaired. The first motor 5 drives the eccentric wheel 6 to rotate, causing the metal platform 2 to vibrate the paper. This vibration disturbs the dust and paper scraps attached to the paper surface, thus achieving a dust removal effect. At the same time, the negative pressure adsorption keeps the paper flat and constrained on the surface of the metal platform 2, reducing paper displacement and bulging during the process. The low-temperature heating of the heating wire 4 promotes the release of residual stress in the paper fibers. Combined with the flattening constraint provided by the negative pressure and the movement of the smoothing rod 19, the smoothing effect on paper wrinkles and curling deformation is increased.
