Description

Technical Field

[0001] The invention relates to the technical field of water-based ink production, and in particular to a water-based ink production system and a production method thereof. Background Art

[0002] Water-based ink, also known as ink, is mainly made by stirring, dispersing and grinding water-soluble resins, organic pigments, solvents and other related additives. Because water-based ink has extremely high environmental protection and safety advantages, it is widely used in various packaging products with strict hygiene requirements.

[0003] However, depending on the packaging product field and technical specifications, the particle size requirements for water-based inks are also different. The particle size of water-based inks is mainly controlled by the grinding rollers of the water-based ink raw materials during the grinding process. There are many factors that affect the product grinding particle size, such as: the grinding gap between the grinding rollers, the grinding texture of the outer wall of the grinding rollers, and the material of the grinding rollers, etc. Therefore, when companies now produce water-based inks of different specifications (i.e., different particle sizes), they generally install and debug multiple production equipment (or production lines) for grinding materials in the workshop. This approach has high requirements on the company's site and has the defect of excessively high production and operation costs.

[0004] In summary, necessary improvements need to be made. Summary of the invention

[0076] S3: The gas entering the upper chamber increases the air pressure in the upper chamber and drives the unloading module to open the unloading port, so that the material in the storage chamber enters the grinding chamber;

[0077] S4: The gas generated by the first air inlet branch is sent into the air inlet chamber through the first air outlet branch, and the grinding roller is driven by the impeller and / or the driving motor to start and grind the material in the grinding chamber;

[0078] S5: The airflow passes through the impeller in the air inlet chamber and is filled into the air gathering chamber. When the air pressure in the air gathering chamber rises, the moving body is driven to move, and the grinding gap between the grinding rollers is reduced, so that the material can be ground to different degrees.

[0079] S6: When the air pressure in the air gathering chamber reaches a preset value, the moving part moves until the air gathering chamber and the exhaust chamber are connected, and the gas in the air gathering chamber pours into the exhaust chamber, dissipates heat to the drive motor, and then enters the grinding roller through the second outlet branch and the air inlet channel;

[0080] S7: After the gas collecting chamber is depressurized, the moving body is reset, and the grinding roller is driven to reset and contact the scraper. The gas entering the grinding roller is sprayed toward the inner wall of the grinding roller through the air jet port and drives the grinding roller to reverse, and the grinding roller is cleaned by the scraper.

[0082] S9: The qualified spare materials filtered by the supply module are sent to the production line of water-based ink, while the qualified spare materials in the particle size part are sent back to the grinding mechanism for further grinding.

[0083] In summary, the present invention has at least the following beneficial effects:

[0084] 1. The invention integrates grinding and screening into one, reducing the site occupation. At the same time, the adjustability of the grinding module during the grinding process enables the water-based ink raw materials to be ground into products of different particle sizes, and screened by the screening module to form spare materials of different specifications. These spare materials of different specifications are used to produce or prepare water-based inks of different specifications. There is no need to install multiple devices to grind the raw materials of the water-based ink to different degrees, thus saving operating costs for the enterprise.

[0085] 2. In order to improve production efficiency (screening efficiency), the screening module provided in the present invention can be intermittently lifted by the air supply system. When the screening module is lifted, the material on the screening module briefly leaves the screen of the screening module due to inertia, thereby avoiding clogging of the screen and increasing the screening efficiency of the screen on the screening module.

[0086] 3. In order to improve the grinding effect, the grinding process of the present invention is carried out by intermittent feeding. Intermittent feeding can reduce the workload of the grinding roller during grinding and can also better grind the material.

[0087] 4. The present invention not only improves efficiency and effect, but also the heat dissipation of the driver (drive motor), the auxiliary start (auxiliary start) of the grinding roller and the cleaning of the grinding roller can all be controlled by the air supply system of the present invention, namely:

[0088] When the grinding roller is assisted to start, the air supply system sends gas into the air cavity to drive the grinding roller to start and rotate using the impeller, so as to drive the motor to drive the grinding roller to move;

[0089] When the driver is cooling, the gas in the air inlet cavity enters the air gathering cavity to dissipate the heat of the driver in the air gathering cavity, and the heat is taken away from the exhaust cavity by the air flow and sent to the grinding roller to assist in cleaning the grinding roller;

[0090] When the grinding roller is cleaned, after the air pressure in the gas gathering chamber is restored, the grinding roller is reset and contacts the scraper. The gas entering the grinding roller can assist the grinding roller to rotate in the opposite direction, and cooperate with the driver to drive the grinding roller to reverse, so that the outer wall of the grinding roller is scraped by the scraper, thereby cleaning the grinding roller and ensuring the grinding effect of the grinding roller.

[0091] In addition, other advantages of the present invention will be demonstrated in the embodiments of the present invention, thereby making the beneficial effects of the present invention more significant. BRIEF DESCRIPTION OF THE DRAWINGS

[0101] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0102] Example 1

[0103] like Figure 1-2 As shown, the present invention discloses a water-based ink production system, which includes, in order of production:

[0104] Grinding mechanism;

[0105] Screening mechanism;

[0106] Supply institutions;

[0107] In this embodiment, the grinding mechanism has a grinding module capable of adjusting the grinding gap, and the screening mechanism has several groups of screening modules, each screening module having a different screening aperture;

[0108] The grinding mechanism and the screening mechanism can be integrated into the same machine body 20, and a plurality of discharge ports 20a are provided on the machine body 20 (a total of 3 discharge ports in this embodiment);

[0109] The material can be ground into spare materials of different particle sizes by the grinding gap of the grinding mechanism, and then screened by different screening modules in turn and discharged to the supply mechanism through each discharge port 20a;

[0110] The supply mechanism comprises a plurality of supply modules (10a, 10b, 10c) which can respectively receive the spare materials discharged from the screening mechanism and send them back to the grinding mechanism or for use after screening.

[0111] In this embodiment, the supply modules (10a, 10b, 10c) correspond to the discharge port 20a, and there are also three of them.

[0112] In this embodiment: the supply mechanism includes:

[0113] Filter body 100;

[0114] The filter element 101 is disposed in the filter body 100 and divides the filter body 100 into a filter chamber 100a and a discharge chamber 100b;

[0115] The discharge port is composed of a first discharge port 102 and a second discharge port 103, and is connected to the filter cavity 100a and the discharge cavity 100b respectively;

[0116] A feed port 104 is provided in the filter body 100 and communicates with the filter cavity 100a;

[0117] The control valve is composed of a first control valve 105a and a second control valve 105b which are arranged at the first discharge port 102 or the second discharge port 103 .

[0118] In this embodiment, each supply module (10a, 10b, 10c) receives the material discharged from each outlet 20a respectively, and the filter diameter of the filter element 101 in each supply module 10 is also different. Taking this embodiment as an example, the filter diameter of the filter element in the supply module 10a is smaller than the filter diameter of the filter element in the supply module 10b, and the filter diameter of the filter element in the supply module 10b is smaller than the filter diameter of the filter element in the supply module 10c.

[0119] refer to Figure 1-2 This embodiment provides the principle of the supply mechanism, and the relevant grinding mechanism and screening mechanism refer to other embodiments:

[0120] During grinding, the material is fed into the grinding mechanism for grinding and passes through different screening modules of the screening mechanism (the apertures of the screening holes of each screening module are different). Therefore, after grinding, the spare materials of different particle sizes can be screened by different screening modules and discharged through different discharge ports. Figure 1 , the larger particle size enters the supply module 10c, the slightly smaller one enters the supply module 10b, and the smaller one enters the supply module 10a for filtering respectively, and the spare material after screening by the supply module 10a can be sent to the supply module 10b for further screening, and because the filter diameter of the supply module 10a is smaller than the filter diameter of the supply module 10b, the supply module 10b can screen out the second specification of spare material. Similarly, after screening by the supply module 10b, it is discharged from the first discharge port of the supply module 10b to the supply module 10c for screening out the third specification, and when the spare material cannot be screened by the supply module 10c, it means that the grinding is unqualified, so the unqualified material will be sent back to the grinding mechanism of the machine body for grinding.

[0121] In summary, the present invention uses three supply modules (10a, 10b, 10c) to screen out three types of spare materials with different particle sizes for use.

[0181] S3: The gas entering the upper chamber increases the air pressure in the upper chamber and drives the unloading module to open the unloading port, so that the material in the storage chamber enters the grinding chamber;

[0182] S4: The gas generated by the first air inlet branch is sent into the air inlet chamber through the first air outlet branch, and the grinding roller is driven by the impeller and / or the driving motor to start and grind the material in the grinding chamber;

[0183] S5: The airflow passes through the impeller in the air inlet chamber and is filled into the air gathering chamber. When the air pressure in the air gathering chamber rises, the moving body is driven to move, and the grinding gap between the grinding rollers is reduced, so that the material can be ground to different degrees.

[0184] S6: When the air pressure in the air gathering chamber reaches a preset value, the moving part moves until the air gathering chamber and the exhaust chamber are connected, and the gas in the air gathering chamber pours into the exhaust chamber, dissipates heat to the drive motor, and then enters the grinding roller through the second outlet branch and the air inlet channel;

[0185] S7: After the gas collecting chamber is depressurized, the moving body is reset, and the grinding roller is driven to reset and contact the scraper. The gas entering the grinding roller is sprayed toward the inner wall of the grinding roller through the air jet port and drives the grinding roller to reverse, and the grinding roller is cleaned by the scraper.

[0186] S8: After step S6, the material is ground into spare materials of different particle sizes and is screened by the screening net and then discharged through various discharge nozzles to various supply modules for filtration;

[0187] S9: The qualified spare materials filtered by the supply module are sent to the production line of water-based ink, while the qualified spare materials in the particle size part are sent back to the grinding mechanism for further grinding.

[0188] refer to Figure 3-8 The principle of this embodiment can refer to the production method of the above-mentioned water-based ink, and in more detail, it is as follows:

[0189] Add the material to be ground into the material storage chamber of this embodiment to wait for the grinding work;

[0190] refer to Figure 4 During grinding, the gas source is started, and in the air flow control closed mode, the gas is sent into the lower chamber from the first air inlet branch through the first air inlet branch, and enters the upper chamber through the connecting port, and is discharged from the first air outlet branch and enters the air inlet chamber. The gas entering the air inlet chamber can drive the impeller to rotate and be discharged from the gas outlet and enter the gas gathering chamber. In this process (see Figure 5-6 ), the rotation of the impeller can drive the grinding roller to rotate, which can assist the motor to control the rotation of the grinding roller;

[0191] After the grinding rollers rotate, the materials passing between the grinding rollers can be ground. The gas entering the gas gathering chamber can increase the gas pressure in the gas gathering chamber and drive the moving body and the moving part to move, so that the grinding rollers are close to each other (horizontally close), so as to achieve the purpose of adjusting the grinding gap (the grinding gap refers to the interval between the grinding rollers). When the moving part moves and separates from the limiting body, the gas gathering chamber is connected with the exhaust chamber, and the gas is discharged from the exhaust port of the exhaust chamber.

[0192] During the above-mentioned activity of the grinding roller, the air flow control valve can be opened. When it is opened, the air pump can deliver the gas from the second air inlet branch into the lower chamber through the second air inlet branch, and lift the screening body, thereby opening the second air outlet branch, so that the gas is discharged from the second air outlet branch and enters the upper chamber from the top of the upper chamber. In this embodiment, since the gas entering the lower chamber from the first air inlet branch can flow in the first flow area of ​​the lower chamber, the air pressure in the first flow area is reduced compared to when there is no fluid flow. Therefore, when the gas enters the second flow area from the second air inlet branch, it is convenient for the gas to overcome the pulling force of the return spring on the screening body and lift the screening body, and smoothly flow out from the second air outlet branch. The action of lifting and lowering the screening body can make the material on the screening body "vibrate" in each screening chamber due to inertia, thereby improving the screening efficiency and preventing blockage.

[0193] The gas entering from the top of the upper chamber (reference Figure 4 ), which can increase the air pressure in the area between the material discharge body and the inner wall of the top of the upper chamber, and control the material discharge body to descend. The descent of the material discharge body can drive the material discharge shaft to drive the blocking body to descend, thereby opening the material discharge port, so that the material in the material storage chamber enters the grinding chamber and is ground by the grinding roller, and a pressure relief valve 90 is arranged in the upper chamber. When the material discharge body descends to the pressure relief valve position, the pressure relief valve is connected with the upper chamber and can discharge the gas in the upper chamber in an open state. At this time, the material discharge body can be reset by the reset spring, so that the material discharge shaft drives the blocking body to re-close the material discharge port, thereby completing the purpose of intermittent material discharge;

[0194] Worthy of mention are:

[0195] In this embodiment, when the gas in the gas collection chamber enters the exhaust chamber, the pressure relief moving part of the gas collection chamber is reset and the drive motor is cooled. Then the grinding roller is reset and contacts the scraper. The gas discharged from the exhaust chamber can be sent into the grinding roller. When the gas is sprayed into the grinding roller, it can drive the grinding roller to reverse (relative to the forward rotation of the grinding, the drive motor also drives the grinding roller to reverse at this time, refer to Figure 8 ), and during the reversal of the grinding roller, the scraper is used to clean the outer wall of the grinding roller. The cleaned material is located on the side of the scraper close to the grinding gap. When the material on the scraper falls, it will also fall into the grinding gap of the grinding roller and be ground to avoid waste.

[0196] Moreover, the gas in this embodiment absorbs the heat of the driving motor in the gas gathering chamber, and when this part of the gas is sent into the grinding roller, it can not only drive the grinding roller to rotate, but also transfer heat to the grinding roller. This is exactly the time when the scraper cleans the grinding roller, and the heating of the grinding roller can enable the scraper to better clean the outer wall of the grinding roller.

[0197] In summary:

[0198] In this embodiment, grinding and screening are integrated into one, and materials of different particle sizes can be produced by using the grinding mechanism and the screening mechanism;

[0199] Moreover, in the production process, the second round of unloading can be carried out after the screening and discharging (or after the screening body is lifted and vibrated). When the screening body does not rise, the air pressure in the area above the unloading body remains unchanged, so no unloading will occur. When the screening body rises, the air pressure in the upper area of ​​the unloading body increases, so that the unloading body descends and unloading is carried out. In the process of rising and falling, the screening body can assist in screening and discharging the materials in the screening chamber, so as to better connect the work of screening vibration, discharging and unloading, avoid clogging of the screening chamber, and thus ensure production efficiency.

[0200] In addition, this embodiment utilizes the gas flow in the first flow zone of the lower chamber and the upper chamber to facilitate the movement of the screening body and the lower material body, and utilizes the air flow through the air inlet chamber to assist the grinding roller to rotate (forward) using the impeller. When the gas enters the grinding roller from the air gathering chamber and the exhaust chamber, it can assist the grinding roller to reverse, which can better assist the drive motor to drive the grinding roller to change the rotation direction.

[0201] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
