Description

TECHNICAL FIELD

[0001] The application belongs to the field of book archives, and particularly relates to a repairing device capable of being used for batch automatic atomization deacidification of single-page documents. BACKGROUND

[0002] Documents are books, periodicals, statutes and the like with historical significance or research value, and are precious literary and artistic wealth inherited by the Chinese nation. Documents include ancient books and modern documents, and are further classified into archives, books, data, calligraphy and painting, and the like. The documents are not only the gem of the Chinese nation's 5,000-year history, but also the core of the preservation and inheritance of Chinese civilization, and are widely used academic materials. Nowadays, due to the passage of time and improper storage methods, a large number of ancient books, calligraphy and painting and modern document materials have been damaged by insect damage and acidification, and the damage degree is increasingly serious. Therefore, the protection and repair of paper document materials are urgent.

[0003] Paper is made of fiber raw materials, and the stability of cellulose is one of the most important conditions for maintaining the physical properties of paper. The main reason for the aging and damage of documents is the acidification of paper. Cellulose is relatively stable under neutral and weak alkaline conditions and is generally not easily hydrolyzed and oxidized, but under acidic conditions, the 1,4-beta-glycosidic bond between glucose is easily broken and cellulose is hydrolyzed. After cellulose is hydrolyzed, the strength of paper is also reduced due to the reduction of the degree of polymerization. When the degree of polymerization of cellulose is reduced to below 200, the paper will be completely brittle and even partially powdered, so that the paper document loses its original use function. In particular, in the process of paper acidification and damage, the acidic substances not only are not consumed, but also are gradually accumulated and retained in the paper material for a long time, causing more and more harm.

[0004] The existing deacidification processes mainly include liquid-phase deacidification and gas-phase deacidification, and the principle of both is to neutralize the acid in the paper with an alkaline deacidifying agent to achieve the purpose of deacidification.

[0005] The deacidification effect of aqueous solution deacidification is good, and the method has the advantages of environmental safety, economy and easy operation, but the paper document deacidified by this method is prone to deformation, shrinkage and the like, and has an impact on some handwriting, and is not easy to scale deacidification.

[0006] The gas-phase deacidification method is a deacidification method using gas evaporation or volatilization. The gas-phase method has the advantage of being suitable for large-scale deacidification, but the process conditions of the gas-phase method are high, and the gaseous storage time is short, is extremely volatile, has a strong odor, and has some safety hazards. In addition, the alkali storage amount is small after treatment, and the method is less used.

[0007] Since the existing single liquid-phase or gas-phase deacidification methods have certain defects, in recent years, some scholars have begun to apply liquid-phase deacidifying agents to batch treatment of paper document materials through atomization.

[0008] The existing batch single-page paper literature atomization deacidification repair equipment has many problems: 1. Manual paper positioning is usually used, and because of the great size difference of the document materials and the different damage degrees, the processing speed and capacity of the equipment are still largely subject to manual operation; 2. The spray device used is usually point spray, which needs to be fixed above the paper running direction to spray to cover the entire paper surface, which can easily cause uneven spraying during operation; 3. For different paper literature materials with complex and variable conditions, too much spraying amount can cause too high paper humidity, and too little spraying amount cannot achieve the best effect, which still needs to be judged by experience, and cannot be automated; 4. The existing equipment can cause paper to drift and displace during atomization operation; 5. A large amount of drug mist is dispersed in the operation space during atomization deacidification, which has a bad smell and even causes pollution, and also causes waste of the drug; 6. The repaired paper often needs to be collected and arranged manually, which is complicated.

[0009] In summary, the equipment for batch single-page paper literature deacidification repair has not been designed so far. SUMMARY

[0010] The present application overcomes the above-mentioned defects and provides a single-page literature batch automatic atomization deacidification repair device. The present application aims to not destroy the original temperature and humidity of the paper, and applies liquid-phase deacidification agent to paper literature deacidification by atomization, which overcomes the shortcomings of single deacidification method; the use of automatic paper feeding device reduces manual operation, and only needs to sort the size of single-page literature materials, which can realize the full automation of the document from paper feeding to repair completion while adapting to multiple sizes of paper, greatly improving the operation efficiency of the equipment; the adjustable spray nozzle of the spray device realizes the spraying of the paper in the full width direction, avoiding uneven deacidification; the combination of the spray and mist suction devices promotes the absorption of the liquid by the paper, avoids the drift of the paper during the atomization deacidification process, and can effectively control the humidity of the repaired paper; and the negative pressure device can recover the excess mist, which is compressed, cooled, and gas-liquid separated, and then the organic solvent is recovered, achieving the effect of reducing pollution and reducing cost.

[0011] A repair device for batch automatic atomization deacidification of single-page documents is characterized by comprising a stainless steel support, rollers, a polyester conveyor belt, a spray device, a mist suction device, an automatic paper feeding device, an automatic paper receiving device, sensors, a negative pressure fan, a motor, an automatic control system, a stainless steel bracket, and an openable protective cover. The motor and control system are installed inside the stainless steel support, and the device is divided into a paper feeding area, a buffer zone, a repair area, and a paper output area. The paper feeding area is a tray for storing single-page documents to be processed, equipped with an automatic paper feeding device. The buffer zone is an open area between the paper feeding area and the repair area. Paper sheets are conveyed by the automatic paper feeding device onto a polyester material conveyor belt and then move towards the repair area through the buffer zone. The repair area is equipped with a spray box, a mist suction box, a chemical recovery device, sensors, and a protective cover. Sensors are installed at the inlet and outlet edges of the repair area to detect the entry and exit of paper sheets. The repair area is divided into upper and lower layers by a polyester conveyor belt. The upper layer is equipped with a spray box that sprays deacidifying agent onto the paper surface. The spray box is connected to a chemical atomizing device. The mist suction device is connected to a negative pressure fan to generate suction at the bottom of the conveyor belt, thereby attracting the paper and accelerating the penetration of the chemical solution. The negative pressure mist suction box is equipped with a chemical absorption device to recover excess chemical solution that has passed through the conveyor belt. The repair area is equipped with a protective cover and a single-opening front door. The paper output area is equipped with a stainless steel tray for collecting repaired single-page documents and is equipped with a guide plate and an automatic paper receiving system.

[0012] Furthermore, it also includes a stepper motor, and a polyester material conveyor belt is installed on the stainless steel bracket. The conveyor belt is driven by rollers, and the drive roller in the rollers is connected to the stepper motor through a coupling. The frequency of the stepper motor can be adjusted by a PLC.

[0013] Furthermore, a PLC control system is fixed inside the stainless steel bracket. The PLC control system integrates and controls the conveyor belt motor, atomizing device, mist suction device, automatic paper feeding device, and negative pressure fan. Through sensor signals and actual requirements, it controls in real time the start and stop of the automatic paper feeding device, the negative pressure of the automatic paper feeding device, the speed of the stepper motor, the start and stop of the spraying device and mist suction device, the flow rate of the spraying device, and the pressure of the negative pressure fan. When batch processing single-page documents, the pages to be processed are first sorted by size. Compatible pages are then positioned within the stainless steel trays in the paper feeding area. The PLC, based on pre-set controls, automatically feeds the pages onto the conveyor belt in the buffer zone. The conveyor belt, operating at the speed set by the PLC control system, transports the documents to the processing area. Upon receiving a sensor signal, the PLC control system activates a spray device to perform atomized deacidification / repair (enhancement, sterilization, insecticidal, etc.) treatment on the pages. Simultaneously, the PLC control system activates a mist-absorbing device below the conveyor belt to accelerate the penetration of the chemical solution and remove excess solution. As the pages move to the processing area exit, the PLC control system, upon receiving a sensor signal, stops the spray and mist-absorbing devices, completing the atomized deacidification treatment of the single-page documents. Furthermore, the PLC can be customized according to different document characteristics and usage conditions to meet various processing requirements.

[0014] Furthermore, it also includes an adjustment and positioning device, wherein the stainless steel bracket of the paper feeding area has an adjustable positioning slot to accommodate single-page document materials of various sizes.

[0015] Furthermore, it also includes a vacuum generator and a suction cup. The automatic paper feeding device is connected to the vacuum generator to generate an adjustable negative pressure and pick up the single-page document material to be deacidified through the suction cup.

[0016] Furthermore, it also includes a control panel, on which a control panel communicating with the PLC is mounted on the stainless steel bracket, for visual adjustment of motor speed and start / stop.

[0017] Furthermore, it also includes a viewing window and a single front door, wherein the protective cover is equipped with a single front door, and the single front door has a viewing window.

[0018] Furthermore, it also includes an atomizing device. A spraying device is located above the conveyor belt inside the repair area. This spraying device is connected to the atomizing device and has two different spraying modes: 1. A square container with a nozzle and an adjustable-width liquid outlet slit. The spraying device atomizes the liquid deacidifying agent and sprays it evenly onto the paper surface through the strip-shaped outlet slit. The spray flow rate and the spray slit width can be adjusted as required. 2. A movable nozzle can be selected as needed. The nozzle is driven by a stepper motor to move laterally, spraying the liquid mist onto the paper.

[0019] Furthermore, it also includes a negative pressure fan, and there is a mist suction device under the conveyor belt inside the repair area. The mist suction device is a square container connected to the negative pressure fan. After it is started, the negative pressure fan creates a negative pressure in the container facing the conveyor belt, which accelerates the flow of the medicine through the paper and the drying of the paper.

[0020] Furthermore, it also includes an automatic paper splicing system. The automatic paper splicing device includes a guide plate and a guide roller. The guide plate is connected to the end of the guide roller, which separates the repaired single sheet of paper from the conveyor belt and transfers it to the stainless steel bracket in the paper output area. The guide plate and stainless steel bracket in the paper output area, under the action of the guide plate, position the paper and accelerate the guide roller, ultimately conveying it to the predetermined splicing area on the stainless steel bracket, completing the entire repair process. The position of the guide plate and the rotation speed of the guide roller can be adjusted as required.

[0021] Furthermore, it also includes a stainless steel bracket and a guide plate, which are set in the paper output area to further position and guide the paper sheet after it has been peeled off by the guide roller, so that the paper sheet finally enters the preset storage area and completes the entire paper sheet atomization deacidification and repair process.

[0022] Compared with the prior art, the advantages of the present invention are:

[0023] 1. The use of negative pressure suction cups to pick up paper replaces a large number of repetitive manual operations, making it possible to deacidify single-page documents on a large scale.

[0024] 2. The paper feeding area uses an adjustable positioning device, which can flexibly adapt to documents of various sizes. Paper sheets with similar sizes can be deacidified at the same time.

[0025] 3. The spraying device sprays liquid that covers the entire paper sheet through adjustable gaps, resulting in uniform and efficient deacidification.

[0026] 4. The combination of spray and mist suction devices ensures that the paper is tightly adhered to the conveyor belt under negative pressure during the atomization and deacidification process, thus preventing drift caused by atomization.

[0027] 5. The mist suction device creates negative pressure inside the mist suction box, absorbs excess spray, compresses, cools, and separates the gas and liquid, and finally sends it to the liquid recovery device, reducing pollution caused by liquid leakage and lowering costs.

[0028] 6. The mist suction device generates a uniform negative pressure area covering the entire conveyor belt, which promotes the absorption of deacidifying agent by the paper, while avoiding paper shrinkage caused by excess moisture residue.

[0029] 7. The guide plate and automatic paper receiving device set in the paper output area can separate the repaired paper from the conveyor belt, and move the paper to the pre-set stainless steel bracket through the guide plate, so as to achieve full automation of the deacidification process.

Detailed Implementation

[0037] The present invention will be further described in detail below with reference to specific embodiments, but the implementation of the present invention is not limited thereto. For process parameters not specifically noted, conventional techniques can be referred to.

[0038] like Figures 1 to 5 As shown, a repair device for batch automatic atomization deacidification of single-page documents includes a stainless steel bracket 1, a conveyor belt 2, a stainless steel support bracket in the paper feeding area 3, a spray device 4, a mist suction device 5, a stainless steel support bracket in the paper output area 6, a control panel 7, a sensor 8, a protective cover 9, an automatic paper feeding device 10, a paper positioning bracket 11, a roller 12, a stepper motor 13, a liquid atomization device 14, a negative pressure fan 15, a single-opening front door 16, a PLC control system 17, a guide plate 18, a paper guide roller 19, a liquid recovery device 20, a negative pressure suction cup 21, and a nozzle 22.

[0039] The stepper motor 13 is installed inside the bracket 1 and connected to the drive roller in the roller 12, driving the polyester mesh belt 2 to move. The PLC control system 17 is installed inside the bracket 1. The bracket 1 is divided into a paper feeding area, a buffer area, a repair area, and a paper output area. The paper feeding area is a stainless steel tray 3 that stores single-page documents to be processed. An automatic paper feeding device 10 is installed on the tray, which includes a negative pressure suction cup 21. A control panel 7 installed on the side of the stainless steel bracket 1 is connected to the PLC 17. The buffer area is an open area between the paper feeding area and the repair area. The paper is conveyed by the automatic paper feeding device to the polyester material conveyor belt 2 and moves to the repair area after passing through the buffer area. The repair area is equipped with a spray device 4, a mist suction device 5, and a liquid recovery system. The device comprises a 20, a sensor 8, and a protective cover 9. The repair area is located inside the protective cover 9. Sensors 8 are installed at the inlet and outlet edges of the repair area to detect the entry and exit of materials. The repair area is divided into upper and lower layers by a polyester conveyor belt. The upper layer is equipped with a spray device 4 for spraying deacidifying / repairing agents onto the paper surface. The spray device 4 has nozzles 22 installed inside and is connected to a liquid atomizing device 14. The lower layer is equipped with a mist suction device 5, which is connected to a negative pressure fan 15 to generate suction at the bottom of the conveyor belt, thereby attracting the paper and accelerating the penetration of the liquid. The liquid absorption device 20 recovers excess liquid that has passed through the conveyor belt. The paper output area is a stainless steel bracket 6 for collecting single-page documents after repair and is equipped with an automatic paper receiving device. The protective cover 9 has a single-opening front door 16. The stainless steel bracket 3 in the paper input area includes an adjustable paper positioning bracket 11. The automatic paper feeding device 10 in the paper input area includes an adjustable pressure negative pressure generator, a lifting and transfer system. The bracket is equipped with a PLC control system 17. In this embodiment, the PLC 17 integrates the spray device 4, the mist suction device 5, the control panel 7, the sensor 8, the automatic paper feeding device 10, the atomizing device 14, and the negative pressure fan 15 for control. By detecting the sensor signals at the inlet and outlet of the repair area, it controls the start and stop of the stepper motor, the motor speed, the start and stop of the fan, the fan speed, the start and stop of the automatic paper feeding device, and the air pressure in real time.The PLC control system 17 integrates the stepper motor, spray device 4, mist suction device 5, automatic paper feeding device 10, and negative pressure fan 15 for control. Through sensor signals and specific requirements, it controls in real time the start / stop of the automatic paper feeding device, the negative pressure of the automatic paper feeding device, the stepper motor speed, the start / stop of the spray and mist suction devices, the flow rate of the spray device, and the pressure of the negative pressure fan. When batch processing single-page documents, the paper pages to be processed are first sorted by size, then compatible paper pages are placed in the stainless steel tray 3 in the paper feeding area for positioning. The PLC then controls the automatic paper feeding device according to preset settings. The paper to be processed is conveyed onto the conveyor belt in the buffer zone. The conveyor belt, operating at the speed set by the PLC control system 17, transports the document to the processing area. Upon receiving a signal from sensor 8, the PLC control system 17 activates the spray device 4 to perform atomized deacidification / repair treatment on the paper. Simultaneously, the PLC control system 17 activates the mist-absorbing device below the conveyor belt to accelerate the penetration of the chemical solution and remove excess solution. When the paper moves to the processing area exit, the PLC control system 17, upon receiving a sensor signal, stops the spray device 4 and the mist-absorbing device 5, completing the deacidification and repair treatment of the single-page document. The spray device, located above the conveyor belt in the processing area, uses a chemical atomizing device to convert various deacidifying chemicals into mist for deacidification treatment of the paper.

[0040] The spraying device 4 employs one of the following two different spraying methods: 1. The nozzle 22 is fixed in the spray box, and the sprayed mist passes through the liquid outlet, which is an adjustable slit. The atomized deacidifying liquid is evenly sprayed onto the surface of the document through the liquid outlet; 2. A movable nozzle 22 can be selected as needed. The nozzle 22 is driven by a stepper motor to move and spray along the direction perpendicular to the paper's movement, as shown in the following example. Figure 5 As shown.

[0041] The mist suction device 5 is a hollow box connected to an adjustable negative pressure fan 15. The pressure is adjusted by a PLC control system 17 to accelerate the penetration of the chemical solution and remove excess solution. The automatic paper receiving device includes a guide plate 18 and a guide roller 19. The guide roller 19 is connected to the end of the guide plate 18, separating the repaired single sheet of paper from the conveyor belt and transferring it to the stainless steel bracket 6 in the paper output area. The conveyor belt 2 is driven by rollers 12.

[0042] In this embodiment, when processing documents in batches, the documents to be processed are first paginated, and then sorted by size. The quantity is determined by the total volume of the device. Single-page documents are placed on the stainless steel tray in the paper feeding area, and the positioning device is adjusted for clamping. After the device is started, the negative pressure suction cup 21 installed in the automatic paper feeding device 10 picks up the paper and transfers it to the conveyor belt 2.

[0043] Deacidification operation mechanism:

[0044] After the paper enters the conveyor belt 2, the sensor 8 at the entrance of the repair area detects the paper entering the repair area and activates the atomizing device 14. The sprayer 22 in the connected spraying device 4 then sprays the medicine onto the paper. Simultaneously, the negative pressure fan 15 is activated, and the connected mist suction device 5 generates negative pressure, adsorbing the paper and accelerating the penetration of the medicine. Excess medicine is collected and sent to the medicine recovery device 20. After repair, the paper is sent out of the repair area. The PLC 17, by detecting the sensor 8 at the repair area exit, controls the atomizing device 14 and the negative pressure fan 15 to stop. The paper is finally transported by the conveyor belt 2 to the paper output area. After being positioned by the guide plate 18 and the guide roller 19, it is finally conveyed onto the stainless steel bracket 6. The above steps are repeated until the next round of repair begins.

[0045] Example 2

[0046] Select an A5-sized document from 1950, paginate it, select 5 pages, and measure the initial pH value of each page. Then place the pages on the stainless steel tray 3 in the paper feed area and adjust their positioning using the paper positioning bracket 11. Add an appropriate amount of 5% sodium propionate solution to the atomizing device, and adjust the relevant parameters of PLC17 via the control panel 7. After completing the above preparations, the device can be started for batch operation. The parameters after repair are as follows:

[0047] No. 1 2 3 4 5 Initial pH value 4.7 4.6 5.1 4.7 5.2 After repair pH value 8.8 8.7 8.9 8.8 8.9

Use a 5% sodium propionate solution for atomized deacidification. The parameters after repair are as follows:

[0050] No. 1 2 3 4 5 6 Initial pH value 4.3 4.7 5.1 4.6 4.9 4.9 After repair pH value 8.5 8.8 8.9 8.6 8.8 8.9
