Description

Technical Field

[0001] The invention relates to the technical field of paper repair, and in particular to a paper repair mechanism. Background Art

[0002] Paper restoration is the process of repairing and maintaining damaged paper, aiming to restore its original structure and appearance and extend its life. Paper restoration usually involves a variety of techniques and methods. Soaking is an important step in the paper restoration process, especially when dealing with fragile or damaged paper. The main purpose of soaking is to allow the paper fibers to reabsorb water and swell, thereby restoring their flexibility and strength. After a long period of drying and use, the fibers of paper may become brittle and hardened, making them easy to break or tear. By soaking, the paper is able to absorb water and soften the fibers, which can reduce the risk of damage when further restoration operations are carried out.

[0003] In the prior art, a Chinese patent document with publication number CN116334955B proposes a paper repair device, which can automatically program the entire mechanized repair process. High-temperature and high-pressure steam enters the steam siphon spray assembly and is directly sprayed onto the repaired paper for cleaning. Such treatment simulates the process of retting and boiling paper, so that the repaired paper fibers can be re-enhanced and restored, and then enters the three repair processes of hot drying, cold setting, and hot setting, so that the paper can achieve the purpose of deacidification, yellow spot removal, and bleaching, and restore the integrity of the repaired paper. However, Consistent with traditional methods, traditional paper repair technology usually relies on manual or simple mechanical methods for soaking. The paper usually needs to be pressed to keep it in the liquid, which can easily cause the paper to be subjected to uneven external forces, thereby increasing the risk of damage, especially when dealing with brittle or thin paper. In traditional drying methods, the removal of moisture often relies on natural convection or static ventilation, which is less efficient and can easily lead to a prolonged drying process. It may also cause moisture accumulation in a humid environment. Therefore, the present application discloses a paper repair mechanism to meet the soaking effect of the paper. Summary of the invention

[0017] Beneficial effects of the present invention:

[0018] 1. This paper repair mechanism is provided with a soaking component, which enables the paper to be automatically soaked during the repair process without external force pressing downward, thereby avoiding direct pressure on the paper. The soaking box utilizes a double-layer storage structure and is provided with an infiltration hole on the top cover, so that water can slowly and evenly penetrate the paper, ensuring that the paper is fully in contact with the soaking liquid to achieve an ideal soaking effect, while effectively preventing the paper from floating in the liquid. The cooperation between the positioning groove and the sliding block enables the soaking box to accurately sink to a suitable soaking depth in the soaking groove. The entire process is driven by a motor to move the lower sliding frame along the slide rail, so that the soaking box gradually sinks from the liquid surface into the liquid. After the soaking process of the paper is completed, it will be moved to the conveyor belt position and enter the drying process.

[0019] 2. This paper repair mechanism is provided with a drying component. When the soaked paper is conveyed to the drying component through a conveyor belt, the fan working mode can be flexibly selected according to different drying requirements. In the cold air mode, the cold air naturally sinks through the guide box, and the inclined structure of the partition plate is used to ensure that the airflow evenly covers the surface of the paper, and the moisture on the surface of the paper can be quickly removed without additional pressure. In the warm air mode, the warm air is pressurized by the wind knife and sprayed to the paper from the air outlet at a higher wind speed, overcoming the natural upward trend, realizing sinking drying, and fully restoring the softness and dryness of the paper fibers. In addition, the placement of the card plate and the positioning rod inside the drying component ensures the stability of the guide box, makes the airflow guidance more precise, and avoids uneven force on the paper caused by uneven airflow direction. The ventilation grille not only promotes the effective exchange of internal and external air and prevents the accumulation of moisture, but also reduces temperature fluctuations to avoid damage to the paper due to excessively high temperatures.

[0020] 3. This paper repair mechanism is provided with a split plate, a first guide plate, a second guide plate and a ventilation grille. The split plate accurately guides the airflow from the sinking plate to the bottom sides of the drying box to avoid direct impact on the paper. The arc plate disperses the airflow and evenly distributes it to the entire paper surface to ensure a gentle drying effect. The inclined setting of the first guide plate guides the airflow to the bottom of the paper to form a fully covered dry airflow, so that the paper can be evenly exposed to the airflow in different areas, avoiding uneven force and damage caused by local drying. The second guide plate further controls the flow direction of the airflow in a vertical manner, so that the moisture is quickly guided to the ventilation grille on the top of the drying box, effectively discharges the moisture, and avoids moisture accumulation in the box. The ventilation grille stacked with inverted V-shaped angle steel not only enhances the ventilation effect of the drying box, but also improves the heat dissipation performance of the box body, keeps the internal temperature moderate, and prevents paper damage caused by excessive temperature. The above structural combination allows the airflow to circulate more three-dimensionally and orderly inside the drying box, effectively improving the drying efficiency and uniformity, while reducing the risk of damage to the paper, ensuring that the entire drying process is efficient, balanced and safe.

[0035] like Figures 1 to 9As shown, a paper repair mechanism comprises a working box 1 and a soaking tank 2 fixedly mounted on one side of the working box 1, a conveyor belt 16 is further arranged on the top surface of the working box 1, and a driving motor 17 for driving the conveyor belt 16 is arranged on one side of the conveyor belt 16; a soaking assembly, which is arranged inside the soaking tank 2 and is used to transport and soak the paper to be repaired; a drying assembly, which is arranged at the middle of the top of the working box 1 and above the conveyor belt 16 and is used to dry the paper after soaking and repairing, wherein a blocking plate 18 is fixedly mounted on one side of the conveyor belt 16 away from the soaking tank 2;

[0036] First, the paper to be repaired is placed in the soaking tank 2, and the soaking component soaks the paper to remove acidic substances or dirt and soften the paper fibers to facilitate subsequent repair. After the soaking is completed, the paper is taken out of the soaking tank 2 and placed on the conveyor belt 16. The drive motor 17 is started to drive the conveyor belt 16 to transport the paper to the bottom of the drying component. The drying component dries the paper to remove residual moisture from the soaking and ensure that the paper gradually recovers to a dry state. After drying, the paper continues to move along the conveyor belt 16 to the baffle plate 18. The baffle plate 18 ensures that the paper remains in the specified position and completes the entire repair process smoothly and without damage.

[0037] like Figures 1 to 5 As shown, the soaking assembly includes a positioning frame 3 fixedly installed inside the soaking tank 2, and slide rails 4 are fixedly installed on both sides of the bottom of the positioning frame 3. A sliding frame 7 is slidably installed on the two slide rails 4. Slide rods 9 are vertically slidably installed on the four corners of the sliding frame 7. A soaking box 8 is fixedly installed on the four slide rods 9. The soaking box 8 is used to place the paper to be repaired. Two groups of rotating wheels 13 are also provided on one side of the positioning frame 3. Belts 14 are commonly sleeved on the two groups of rotating wheels 13. A connecting plate 15 is fixedly installed on one side of the sliding frame 7, and the other side of the connecting plate 15 is fixedly connected to one side of the belt 14. One of the rotating wheels 13 is fixedly connected to the output end of the external motor, a positioning plate 5 is also fixedly installed in the middle of the bottom of the positioning frame 3, a positioning groove 6 is penetrated on the positioning plate 5, and the positioning plate 5 is arranged in a V shape. A square groove is opened in the middle of the bottom surface of the working box 1, and the middle of the positioning plate 5 is penetrated by the square groove. A positioning column 10 is fixedly installed in the middle of the bottom surface of the soaking box 8, and a sliding block 11 is rotatably installed on one side of the positioning column 10. The sliding block 11 is slidably installed in the interior of the positioning groove 6. The soaking box 8 is arranged in a double-layer storage box, and a plurality of infiltration holes 12 are opened on the top cover of the soaking box 8;

[0038] The paper to be repaired is placed in the soaking box 8, and the motor drives one of the rotating wheels 13, and the belt 14 drives the other rotating wheels 13 to rotate, and at the same time, the belt 14 drives the connecting plate 15 and the sliding frame 7 to move along the slide rail 4, and the soaking box 8 gradually sinks under the drive of the positioning groove 6, and the soaking box 8 sinks into the soaking tank 2. The positioning column 10 in the soaking box 8 is accurately positioned under the cooperation of the sliding block 11 and the V-shaped positioning groove 6, ensuring that the soaking box 8 can be lowered into the soaking liquid when moving, and the infiltration hole 12 of the soaking box 8 is ensured. The water retention can slowly and evenly penetrate into the paper to achieve an ideal soaking effect. After the soaking is completed, the sliding frame 7 moves the soaking box 8 to the vicinity of the conveyor belt 16 under the drive of the motor, waiting to enter the drying component for processing. The soaking box 8 is a double-layer storage box structure, with an infiltration hole 12 opened on the upper part, and a through hole is also provided at the bottom of the soaking box 8 to allow the soaking liquid to flow out after the soaking is completed. The double-layer storage structure of the soaking box 8 can be a top cover that is flipped to place the paper to be repaired, and then the top cover covers it to prevent it from floating upward during soaking.

[0039] like Figures 5 to 9 As shown, the drying assembly includes a drying box 19 fixedly installed in the middle of the upper end of the working box 1, a first fan 21 is arranged on the top surface of the drying box 19, a guide box 22 is movably installed inside the drying box 19, two air inlets 23 are arranged on the top surface of the guide box 22 corresponding to the first fan 21, a partition plate 24 is arranged inside the guide box 22, the lower part of the guide box 22 is arranged in an inclined shape, and a plurality of guide plates 25 are arranged at the inclined part of the lower part of the guide box 22, an extension plate 26 is fixedly installed on one side of the guide box 22, a second fan 27 is arranged on one side of the extension plate 26, and the second fan 27 is arranged on the lower side of the extension plate 26. An air inlet pipe 28 is provided on one side of the fan 27, and the air inlet pipe 28 runs through the drying box 19. A diverter box 29 is also fixedly installed on the top surface of the guide box 22. The other side of the second fan 27 is connected to the diverter box 29. Two wind knives 30 are respectively provided on the side of the guide box 22 away from the extension plate 26. A plurality of air outlets 31 are provided below the two wind knives 30. Both wind knives 30 are connected to the diverter box 29. A card plate 32 is fixedly placed on both sides of the drying box 19. Positioning rods 33 adapted to the card plate 32 are provided on the top of both sides of the guide box 22.

[0040] Specifically, the first fan 21 in the drying component can be set as a cold air fan, and the second fan 27 can be set as a warm air fan. The intelligent switching and precise diversion of cold air and warm air bring remarkable practical effects. When the soaked paper is conveyed to the bottom of the drying component through the conveyor belt 16, the corresponding fan is started according to demand to achieve the best drying effect. When the first fan 21 is started as a cold air fan, the cold air naturally flows downward through the air inlet 23 of the guide box 22, and the cold air is guided to the surface of the paper along the inclination of the partition plate 24 for uniform cold air drying, and moisture can be quickly dissipated without additional pressure. If the paper needs to be dried at a higher temperature, the second fan 27 is started, and the warm air passes through the wind knife 30 It enters the diversion box 29 and is evenly guided to the surface of the paper from the air outlet 31 with a relatively large pressure. The warm air overcomes the upward trend after being pressurized by the wind knife 30, realizing downward covering drying, ensuring that the paper fibers are gently restored to a dry state. During the whole process, the placement of the card plates 32 and the positioning rods 33 on both sides cooperate to stabilize the position of the guide box 22, making the airflow more precise; the ventilation grille 20 promotes air exchange inside and outside the box, removes moisture, and reduces internal temperature fluctuations, avoiding damage to the paper due to moisture accumulation and excessive temperature, so that the drying component can not only ensure full coverage of the paper during drying, but also avoid uneven force, thereby improving the drying efficiency and allowing the paper to complete the entire repair process smoothly and without damage.

[0041] like Figure 6 , Figure 7 As shown, a sinking plate 34 is fixedly installed at the middle of the top of the drying box 19, and both sides of the bottom surface of the sinking plate 34 are provided with a dividing plate 35, and the dividing plate 35 is provided with an arc plate 36. Two groups of inclined first guide plates 37 and two groups of vertical second guide plates 38 are also provided on both sides of the drying box 19. The two groups of first guide plates 37 are arranged opposite to each other. Ventilation grilles 20 are provided on both sides of the drying box 19, and the ventilation grilles 20 are formed by stacking a number of inverted V-shaped angle steels.

[0042] When the soaked paper is conveyed to the bottom of the drying assembly by the conveyor belt 16, the fan in the drying assembly starts and conveys warm air or cold air to the sinking plate 34 and the dividing plate 35, and guides the airflow to the bottom sides of the drying box 19 through the dividing plate 35. At the same time, the arc plate 36 disperses the airflow so that the airflow flows evenly to both sides. The first guide plate 37 guides the airflow to the bottom of the paper at an inclined angle to achieve full coverage of the paper, ensuring rapid and uniform drying of the paper. During the flow of the air duct, the remaining moisture is guided to the ventilation grille 20 through the second guide plates 38 vertically arranged on both sides to discharge from the drying box 19, and finally the paper is dried. After achieving the drying effect, it continues to move along the conveyor belt 16 to the baffle plate 18, and the entire repair process is successfully completed. The combination of the first guide plate 37 and the second guide plate 38 guides the airflow to form a multi-level flow, making the airflow inside the drying box 19 more three-dimensional and circulated in an orderly manner, thereby improving the efficiency of removing moisture from the paper and effectively preventing uneven force on the paper caused by airflow in a single direction. The ventilation grille 20 formed by stacking inverted V-shaped angle steels enables the exchange of air inside and outside the drying box 19, improves the ventilation effect, prevents moisture accumulation in the box, and also enhances the heat dissipation performance of the equipment to avoid damage to the paper caused by excessive temperature.
