Description

Technical Field

[0001] The invention relates to the field of printing technology, and in particular to a mixing and storing device for preventing printing ink from crusting and an implementation method thereof. Background Art

[0002] Existing offset inks are usually stored in iron cans or composite bags. If a can or bag of ink is not used up after opening, reuse will not only affect product quality, but also cause resource waste and environmental pollution. Due to the characteristics of offset ink itself, the ink will quickly form a crust on the surface after contact with air. If it is used again, solid crust residue will cause printing failures such as drawing, dirty spots, and color spots, and will also damage the transfer rubber cloth; the wasted ink crust not only wastes resources, but also pollutes the environment.

[0003] On the other hand, in order to obtain specific colors or printing effects, primary color inks are often used to mix spot color inks or modified inks in the printing process. A certain proportion of varnishing oil is added during the mixing process. Since varnishing oil is highly volatile, exposure to the air during mixing will have an adverse effect on the physical and mental health of the workers, and it is generally difficult to preserve for a long time, and its storage difficulty is higher than that of primary color inks.

[0004] It is currently known that it is difficult to utilize 100% of the offset ink in containers or devices for mixing and storing ink, because the ink will always adhere to the inner wall of the container or device to a certain extent (commonly known as "hanging on the wall"); moreover, if the container or device with ink is discarded, it will have a direct impact on the environment. If it is cleaned, the cleaning solvent will also have an impact on the environment.

[0005] In view of the above technical problems, the present application proposes a mixing and storage device for preventing printing ink from crusting, which can not only ensure that the material can be conveniently taken as needed during use, but also ensure that the stored ink is effectively isolated from the air to avoid crusting.

[0006] It can be seen that the existing technology still needs to be improved and enhanced. Summary of the invention

[0007] In view of the above-mentioned deficiencies in the prior art, the purpose of the present invention is to provide a mixing and storage device and implementation method for preventing printing ink from crusting, aiming to solve the technical problem that the ink barrels used in the prior art cannot be effectively isolated from the outside world, which easily leads to ink crusting.

[0011] Furthermore, in the mixing and storing device for preventing printing ink from crusting, a second groove is provided on the base corresponding to the flange, and the flange is located in the second groove.

[0012] Furthermore, in the mixing and storing device for preventing printing ink from crusting, the inclination angle of the inclined surface is not less than 3°.

[0013] Furthermore, in the mixing and storage device for preventing printing ink from crusting, the upper surface of the boss, the inner wall of the cylinder and the surface of the agitator are provided with an anti-sticking layer, and the method for setting the anti-sticking layer is: first use steel sand for sandblasting, the steel sand mesh number is 80-200; then spray 1 to 3 layers of Teflon layer with a total thickness of 5 to 30 microns; then bake at a temperature of 200 to 400°C for 20 to 100 minutes, and then take out and cool naturally.

[0014] The present application also provides a method for implementing the preparation and storage of printing ink to prevent the formation of skin, comprising the following steps: (1) Pour one or different amounts of ink and varnish in a pre-set ratio into the cylinder, connect the cover plate and the cylinder, and install the motor and agitator at the threaded hole; (2) Start the motor and stir at a speed of 100 to 300 rpm for 5 to 30 minutes, then remove the motor and stirrer and install the cover on the threaded hole; (3) Open the inflation valve and adjust the air pressure in the cylinder to 0.12-0.25Mpa; open the dispensing valve and take out the ink as needed; (4) Close the material dispensing valve and the air charging valve, open the three-way valve to connect the cylinder to the outside atmosphere, and close the three-way valve when the pressure inside the cylinder is balanced with the atmospheric pressure; (5) Open the air extraction valve, adjust the air pressure inside the cylinder to 0.02-0.05MPa, and close the air extraction valve.

[0021] The present invention provides a mixing and storing device and implementation method for preventing printing ink from forming a skin. In order to make the purpose, technical solution and effect of the present invention clearer and more specific, the present invention is further described in detail below. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0022] See also Figures 1 to 4 The present invention provides a mixing and storage device for preventing printing ink from crusting. The accompanying drawings are only used to explain the structural principle and are not proportional to the actual product. The accompanying drawings only depict structures related to the invention of this application, and some conventional structures are not specifically depicted. Different names for various components are used herein only for the convenience of explanation and are not intended to limit this application.

[0023] A mixing and storing device for preventing printing ink from crusting comprises a base 1, a barrel 2, and a cover plate 3 detachably connected to the barrel, wherein the base is provided with a boss 11, the upper surface of the boss is an inclined surface 111, and the boss extends upward into the interior of the barrel; a material taking tube 49 is provided at the bottom end of the barrel corresponding to the inclined surface, and a material taking valve 59 is provided on the sampling tube; an air charging tube 41, an air exhausting tube 42 and a balance tube 43 are provided on the cover plate, an air charging valve 51 is provided on the air charging tube, and an air exhausting valve 52 is provided on the air exhausting tube; a three-way valve 53 is provided on the balance tube; a threaded hole 301 is provided in the middle of the cover plate, and a motor 61 is detachably connected to the threaded hole, and the motor is connected to a stirrer 7 (including a stirring rod 71 and a stirring blade 72), and the stirrer is located inside the barrel; an anti-sticking layer (not shown in the figure) is provided on the upper surface of the boss (i.e., the inclined surface 111), the inner wall of the barrel, and the surface of the stirrer.

[0024] In actual use, the above-mentioned inflation pipe is connected to the workshop air supply system, the exhaust pipe is connected to the exhaust pump, and the inflation valve and the exhaust valve can respectively steplessly adjust the inflation and exhaust speeds.

[0025] The cover plate is preferably made of stainless steel with a thickness of 2-5 mm. The cylinder is made of high temperature resistant tempered glass with a thickness of 5-10 mm. A ruler (not shown in the figure) is provided on the side wall of the cylinder for visually checking the ink inventory and usage.

[0026] The cover plate and the cylinder are preferably connected by a buckle (not shown in the figure), and the structure of the buckle can be various and is not limited here. In order to ensure good sealing, a sealing ring can be provided between the cover plate and the cylinder. In practical applications, the motor is not needed after the ink is prepared, and the motor can be removed, and then a cover (not shown in the figure) can be screwed on the threaded hole of the cover plate.

[0027] The inflation valve 51 and the exhaust valve 52 are preferably one-way valves. Specifically, relative to the cylinder, the inflation valve is a one-way valve that allows air to enter but not exit, and the exhaust valve is a one-way valve that allows air to exit but not enter. In practical applications, the inflation pipe is used to connect to a compressor (not shown in the figure) or a compressed air source in a workshop, and the exhaust pipe is used to connect to an external vacuum pump (not shown in the figure).

[0028] One end of the three-way valve is connected to the cylinder, and the other end is connected to the atmosphere ( Figure 1 The exhaust pipe 45 in the cylinder is connected to the atmosphere. When the balance pipe 43 of the three-way valve is connected to the exhaust pipe 45, the air pressure in the cylinder reaches equilibrium with the external atmospheric pressure). One end is connected to a pressure gauge 431 (for measuring the air pressure in the cylinder). During operation, the on-off of the three-way valve is controlled according to the specific situation (further described below).

[0029] Figure 2 The diagram schematically shows the layout of the inflation pipe, the exhaust pipe and the balance pipe on the cover plate. The inflation pipe, the exhaust pipe and the balance pipe are arranged at equal intervals in the circumferential direction, and the distance between the center of the root of the inflation pipe, the exhaust pipe and the balance pipe and the edge of the cover plate is 1 / 3 to 1 / 2 of the radius of the cover plate.

[0030] See also Figure 3 The motor 61 is arranged in the housing 62, and the bottom end of the housing 62 is provided with internal and external thread nuts for connecting with the threaded holes of the cover plate.

[0031] Preferably, the inner diameter of the cylinder is 20-25 cm, and the depth of the cylinder is 30-35 cm.

[0032] Furthermore, a first groove 101 is provided on the base corresponding to the bottom end of the cylinder, and the bottom end of the cylinder is inserted into the first groove. This arrangement facilitates a stable connection between the cylinder and the base, and the cylinder will not tip over. In addition, in actual use, a sealing ring 29 is provided in the first groove to improve the sealing performance and prevent ink from leaking outward.

[0033] Furthermore, a flange 21 is provided at the lower part of the cylinder, and the flange is connected to the base by bolts ( Figure 1 The center line 211 is used to represent the bolt.) This arrangement facilitates quick disassembly and assembly between the cylinder body and the base.

[0034] Furthermore, a second groove 102 is provided on the base corresponding to the flange, and the flange is located in the second groove. This arrangement facilitates the connection between the flange and the base, and further ensures that the ink will not leak out. Figure 4 It can be observed that a plurality of threaded holes 103 are provided in the second groove, and the bolts can be screwed into the corresponding threaded holes 103 after passing through the flange.

[0035] Preferably, the inclination angle of the inclined surface is not less than 3°. It should be noted that it is understandable that the larger the inclination angle of the inclined surface, the easier it is for the ink to flow to the material dispensing valve, but correspondingly, the larger the space occupied by the boss in the barrel. In order to ensure the convenience of dispensing and minimize the space occupied by the boss in the barrel, the inclination angle of the inclined surface is preferably 3°~5°.

[0036] Furthermore, the upper surface of the boss and the inner wall of the cylinder are treated with steel sand blasting before the anti-sticking layer is provided. The steel sand blasting can improve the adhesion of the anti-sticking layer, making the anti-sticking layer more firmly connected. Preferably, the above-mentioned sand blasting uses 200 mesh steel sand.

[0037] Preferably, the anti-sticking layer is Teflon (ie, polytetrafluoroethylene), which has a good anti-sticking effect and will not react with the ink in the barrel.

[0038] The present application accordingly provides a method for implementing the preparation and storage of printing ink to prevent the formation of skin, comprising the following steps: (1) Pour different inks into the cylinder according to the preset proportions, connect the cover plate and the cylinder, and install the motor and agitator; (2) Start the motor and stir at 100 rpm for 30 minutes, then remove the motor and stirrer; install the cover on the threaded hole; (3) Open the inflation valve and adjust the air pressure in the cylinder to 0.12-0.25Mpa; open the dispensing valve and take out the ink as needed; (4) Close the material dispensing valve and the air charging valve, open the three-way valve to connect the cylinder to the outside atmosphere, and close the three-way valve when the pressure inside the cylinder is balanced with the atmospheric pressure; (5) Open the air extraction valve. When the air pressure inside the cylinder is adjusted to 0.02-0.05MPa, close the air extraction valve.

[0039] (6) When it is necessary to take material again, first open the three-way valve to connect the cylinder to the outside atmosphere. When the pressure inside the cylinder is balanced with the atmospheric pressure, close the three-way valve and repeat steps (3) to (5).

[0040] Through the above analysis, it can be seen that the technical solution provided by the present application realizes the preparation and storage of printing ink. By setting up components such as an air filling valve and an air extraction valve, the ink can be easily taken out, and it can be effectively isolated from the outside world during storage, so as to avoid the formation of ink crust in the cylinder, avoid waste, and ensure the subsequent printing quality.

[0041] It is understandable that those skilled in the art can make equivalent substitutions or changes based on the technical solution and inventive concept of the present invention, and all these changes or substitutions should fall within the protection scope of the present invention.
