Description

Technical Field

[0001] The utility model relates to the technical field of paper deacidification, in particular to an intelligent operating system for paper deacidification equipment. Background Art

[0002] Paper is the main carrier of materials such as ancient books, calligraphy and paintings, and archives, and has multiple values ​​such as history, collection, and research. The acidification of paper will cause the degradation of cellulose, hemicellulose, and lignin, the main components of paper, resulting in a decrease in the degree of polymerization, weakening of the paper strength, and even flocculation. At present, the deacidification equipment produced in my country is mainly handheld and fixed. Its working principle is to spray the deacidification liquid onto the surface of the paper under pressure. For handheld equipment, since it is manually held, it is usually affected by human factors, and it is difficult to accurately control the amount and uniformity of the deacidification liquid sprayed on the paper, which is easy to cause uneven deacidification. At the same time, manual operation also has the problem of low efficiency. For fixed deacidification equipment, its working principle is to manually fix the paper to be processed on the deacidification operating table, use a spray device to spray the deacidification liquid onto the surface of the paper, and after the deacidification operation is completed, manually peel off the paper and place the paper in place or transfer it for drying. Among the problems, for the scenario of using aqueous deacidification liquid, when the paper is sprayed, the humidity of the paper will increase. For paper with low wet strength, it is very easy to cause secondary damage such as deformation or cracking of the paper during the process of peeling or transferring; secondly, after aqueous deacidification, the paper is dried under natural conditions. Due to the inconsistent evaporation speed of the water on the paper surface, it is easy to cause the paper to curl after drying, and it is difficult to ensure the flatness of the paper after deacidification. At present, my country's deacidification equipment is mainly based on a single module, that is, the paper preparation, deacidification, and drying modules are operated separately. 1) In the paper preparation module, it is necessary to manually lay the paper to be deacidified one by one on the deacidification panel. After the deacidification is completed, the paper is peeled off and transferred for drying, which requires more operators and has low efficiency. 2) In the deacidification module, a mist spray device is mostly used to spray the deacidification liquid on the surface of the paper for deacidification. For handheld deacidification equipment, it is difficult to quantify the sprayed liquid, and it is not easy to control the amount of liquid sprayed on the surface of the paper, resulting in uneven dispersion of the deacidification liquid on the surface of the paper. In addition, the deacidification panels currently used mostly use belt conveyors, so that the paper after deacidification needs to be removed from the conveyor belt in a timely manner, which is inefficient. However, for deacidification equipment using aqueous deacidification liquid, after the paper is deacidified, due to the increase in paper moisture, when the wet strength of the paper is reduced, it is easy to cause the paper to break and deform during the transfer process, causing secondary damage to the paper. 3) In the drying module, at present, the paper after deacidification is mostly dried by natural air drying, vacuum drying or air drying oven drying. Among them, natural air drying is particularly prone to deformation problems such as paper curling. 4) In addition, at the current stage, the paper preparation, deacidification, and drying modules are operated separately, which requires a lot of manpower and is inefficient, making it difficult to complete batch and efficient operations.

[0003] Therefore, how to improve the processing efficiency and deacidification effect of paper deacidification equipment has become a technical problem that needs to be solved urgently. Utility Model Content

[0038] According to another embodiment of the utility model, the working principle and workflow of the intelligent operating system of the paper deacidification equipment of any of the above embodiments are disclosed:

[0039] The utility model mainly comprises: a paper preparation table (paper preparation part), a paper deacidification operation table (deacidification part), a paper drying table (drying part), and a transporting mechanical arm (transporting part); the main function of the paper preparation table is that the mechanical arm grabs a single sheet of paper placed on the single-page paper loading table and places it on the paper tray each time, and each paper tray can hold three single-page papers, and the module comprises a pretreatment table bracket, a paper tray and a single-page paper loading table, and three grooves are arranged on the paper tray, and three sheets of paper can be placed at the same time; the main function of the paper deacidification operation table is that the deacidification mechanism deacidifies the single sheet of paper placed on the paper tray, and the module comprises a paper deacidification bracket, a paper tray, a heating stirring tank, a quantitative constant pressure module, an XY plane motion module, a quantitative spraying device, a vacuum adsorption table, a vacuum pump and related pipelines; the main function of the paper drying table is that the deacidified paper is dried, and the module comprises a drying bracket, a heating water tank, a water pump, a water bath heating table and a temperature sensor, etc.

[0040] The detailed workflow includes:

[0041] 1. Paper preparation:

[0042] The paper preparation table is equipped with a paper tray and unprocessed paper. The unprocessed paper sheets are stacked together. The robotic arm absorbs the single paper through the suction cup on the multi-functional robotic arm at the front end, and lays it flat in the groove on the paper tray. There are three grooves on the paper tray. The robotic arm places the absorbed paper in the three paper trays of the paper tray in turn. This design can achieve efficient paper preparation.

[0043] 2. Deacidification treatment:

[0044] The robot arm lifts and locks the paper support on the paper pretreatment table through the special clamp on the multifunctional robot arm at the front end, and places it in the correct position on the paper deacidification operation table; then the robot arm releases the special clamp on the multifunctional robot arm at the front end of the robot arm to release the paper support. This design can realize the integrated transfer of the paper to be processed and the paper support to the deacidification table, avoiding or reducing the damage of the paper during the transfer process;

[0045] The paper deacidification operation table is equipped with a deacidification solution stirring barrel, and the stirring barrel is equipped with a stirrer and a heater. The stirrer can fully stir the deacidification solution, and the heater can raise the solution to an appropriate temperature to achieve the best deacidification effect.

[0046] A constant pressure quantitative module is provided on the paper deacidification operating table, and a gear pump, a motor, a pressure accumulator and a solenoid valve are provided on the module, wherein the gear pump is a quantitative pump, which can make the volume of the discharged solution the required volume, thereby meeting the quantitative requirement; a pressure sensor is also provided on the module, when the pressure of the solution pumped out by the gear pump reaches the required requirement, the pressure sensor can collect the pressure on the pipeline, and the control system controls the solenoid valve to open, so that the discharged solution can meet the quantitative and required pressure requirements; the role of the pressure accumulator is that when the speed of the gear pump fluctuates, the flow rate and pressure of the pumped liquid will also fluctuate, and the pressure accumulator is connected in series on the pipeline. When the pressure on the pipeline changes, the internal compressed air of the pressure accumulator can quickly compensate for the pressure on the pipeline, so that the pressure will not fluctuate greatly, thereby stabilizing the pressure on the pipeline; the role of the solenoid valve is that the pressure of the liquid pumped out by the water pump is relatively low at the initial moment, and the solenoid valve is connected in series on the pipeline, so that the pipeline can be closed, and the solenoid valve can be opened when the pressure reaches the required value;

[0047] There is a nozzle on the paper deacidification operation table, which can spray mist liquid to ensure that the liquid sprayed in a certain area is evenly sprinkled on the paper; because the uniformity of the nozzle spray is greatly affected by the liquid pressure on the pipeline, the pressure on the liquid pipeline is required to be stable;

[0048] A plane motion module is provided on the paper deacidification operation table, which can realize the movement in the X direction and the Y direction in the plane. At the same time, the plane motion module is fixed to the nozzle, so that the spray sprayed by the nozzle can be quantitatively and evenly sprinkled on the paper on the paper tray in cooperation with the quantitative device;

[0049] A paper support vacuum base is provided on the paper deacidification operation table, and the interior of the base is a cavity, and the cavity is connected to a vacuum pump through a pipeline to achieve a negative pressure effect in the cavity; a sealing rubber ring is also provided around the paper support vacuum base, and the sealing rubber ring is connected to the paper support upward, so that a negative pressure cavity can be formed between the paper support, the sealing rubber ring and the paper support vacuum base;

[0050] A plurality of through holes are arranged in the three grooves on the paper tray, which are connected to the negative pressure chamber. When the deacidification liquid is sprayed, the vacuum pump starts to work, and the negative pressure sucks the paper through the multiple through holes in the grooves on the paper tray, preventing the paper from moving and curling during the deacidification process, thereby ensuring the flatness and uniformity of deacidification. When the deacidification is completed, the vacuum pump stops working, the negative pressure chamber returns to normal atmospheric pressure, and the robotic arm can smoothly carry the paper tray to the drying table.

[0051] 3. Drying treatment:

[0052] The robot arm lifts and locks the paper support on the deacidification operation table through the special clamp for the paper support on the multifunctional robot arm at the front end, and places it in the correct position on the paper drying table; then the robot arm releases the special clamp for the paper support on the multifunctional robot arm at the front end of the robot arm, thereby releasing the paper support;

[0053] The paper drying table is equipped with a heating bucket, which can raise the solution to an appropriate temperature and provide hot water for drying the paper.

[0054] The paper drying table is equipped with a water pump, which can circulate the hot water used for drying and finally return it to the hot water bucket;

[0055] A water bath heating tray is provided on the paper drying table, and the paper support is located above the water bath heating tray and in contact with the water bath heating tray, so that the heat of the water bath heating tray can be transferred to the paper support, so that the paper support is heated up, thereby drying the deacidified paper on the paper support;

[0056] The paper drying table is equipped with a temperature sensor to monitor the temperature of the water bath heating tray to prevent the temperature from being too high or too low during the drying process;

[0057] There are multiple layers of drying tables arranged on the paper drying table. Since the drying time is longer than the deacidification time, multiple paper trays can be dried at the same time, thus improving the efficiency of the entire system.

[0058] The multi-layer drying tables are connected by pipes at the head and tail, the first section of the water pipe of the whole module is connected to the water pump, and the last section of the water pipe of the whole module is connected to the water bucket, so as to realize the water circulation of the whole module;

[0059] 4. Robotic arm handling:

[0060] The robot arm has four degrees of freedom, namely movement in the X, Y and Z directions, and rotation around the Z axis;

[0061] The robot arm is equipped with a multifunctional manipulator: it can carry the paper tray and absorb a single paper;

[0062] The robot arm is equipped with a multifunctional manipulator, a robot gripper, an electromagnetic push rod and a vacuum suction cup; the mechanical gripper is provided with a circular hole with the same spacing and size as the hole on the paper tray. The circular hole is provided with an electromagnetic push rod. When the robot arm drives the robot gripper to move to the same position as the hole on the paper tray, it is considered to be in place. At this time, the two electric push rods start to move. The electromagnetic push rod pushes the internal push rod and inserts it into the circular hole on the paper tray, thereby locking the paper tray. With two electromagnetic push rods, the rotation of the paper tray can be limited, thereby achieving stability during the handling process;

[0063] The multifunctional manipulator is equipped with six vacuum suction cups, which can absorb the paper;

[0064] The height of the vacuum suction cup on the multifunctional manipulator is higher than the paper holder clamp, so that during the process of adsorbing paper, the paper holder clamp will not affect the adsorption of paper;

[0065] When carrying the paper tray, the electromagnetic push rod is in front and the vacuum suction cup is in the back, so that the vacuum suction cup will not affect the paper tray during the paper tray carrying process;

[0066] In summary, the utility model adopts a robot to efficiently lay paper, and transfers the paper and the paper tray in an integrated manner, thereby improving the paper laying efficiency, reducing labor costs, and reducing the problem of damage to the paper during the transfer process; the quantitative pump and the planar motion module can strictly control the quantitative and uniform spraying of the deacidification liquid onto the paper surface; the use of a hydrothermal temperature control drying device can achieve visual and fine temperature control, and the multi-layer drying table designed at the same time can greatly improve the drying efficiency; the robot arm assists in the integrated operation system of paper preparation, deacidification, and drying, which is efficient in operation, reduces manpower, and ensures precise operation.

For those skilled in the art, the utility model can have various modifications and changes.
