Description

Technical Field

[0001] This application relates to the field of ink storage technology, and in particular to a storage device for a non-aqueous printing ink composition. Background Technology

[0002] Ink is a homogeneous mixture composed of colorants, binders, fillers, additives, etc. It can be printed and dries on the printed surface. It is a colored paste-like adhesive with a certain degree of fluidity. When storing ink, it should be kept away from fire and heat sources as much as possible to prevent accidents. Non-water-based printing ink compositions require special care during storage.

[0003] A search revealed that publication number CN219097434U discloses a printing ink storage device. A transmission assembly installed on the lid facilitates the rotation of two scraper supports and multiple cross supports. Two scrapers on the scraper supports scrape off the solid printing ink adhering to the inner wall of the storage tank. Stirring blades on the cross supports ensure uniform stirring of the printing ink, reducing ink stratification, improving the thawing effect and fluidity of the ink, facilitating ink use, and preventing clogging of the printing equipment's mesh and printing plate during the printing process.

[0004] Regarding the aforementioned technologies, the inventors believe the following technical defects require improvement: The device employs a rapid stirring structure; excessively high stirring speeds can lead to excessive shear force, damaging the rheological properties of the ink and consequently reducing product quality. Furthermore, oxygen significantly promotes the oxidative curing of water-based inks, causing surface skinning and increased viscosity during storage. Utility Model Content

[0005] This application provides a storage device for non-aqueous printing ink compositions to address the following technical problems: The aforementioned device employs a rapid stirring structure; excessively high stirring speeds can lead to excessive shear forces, damaging the rheological properties of the ink and consequently reducing product quality. Furthermore, oxygen significantly promotes the oxidative curing of aqueous inks, causing surface skinning and increased viscosity during storage.

[0006] This application provides a storage device for a non-aqueous printing ink composition, employing the following technical solution:

[0007] A storage device for a non-aqueous printing ink composition includes a storage tank, a cooling and heating integrated unit, a return pipe, a nitrogen cylinder, a low-frequency vibration component, and a lifting component. The cooling and heating integrated unit is disposed on the outside of the storage tank. The return pipe is installed on the outside of the output end of the cooling and heating integrated unit, and the top of the return pipe is tightly fitted to the inner surface of the storage tank. The nitrogen cylinder is connected to the inner wall of the storage tank through a gas pipe. The low-frequency vibration component is movably connected to the middle of the storage tank.

[0008] The storage tank is used to seal and store non-aqueous printing inks to prevent external contamination.

The annular disk is movably connected to the inside of the storage tank. The outer side of the planetary gears is inserted into one side of the nylon damping disk. The electric vibrator is inserted into the inner side of the middle of the nylon damping disk.

[0010] In one feasible technical solution of this application, a main gear is fixedly connected to the side of the drive shaft near the annular disk, and the external teeth of the main gear mesh with the external teeth of the planetary gear.

[0011] In one feasible technical solution of this application, the lifting assembly includes a boss, a hydraulic cylinder and a hollow bracket.

The bottom of the hollow bracket is fixedly connected to the top surface of the annular disc.

[0012] In one feasible technical solution of this application, the annular disk is further provided with an annular rack that is adapted to the external teeth of the planetary gear.

[0013] In one feasible technical solution of this application, a limiting frame is rotatably connected to the inner side of the annular disk, and the outer side of the limiting frame is rotatably connected to the inner side of the planetary gear.

[0014] In one feasible technical solution of this application, an air pump for supplying hot gas into the storage tank is also installed on the outside of the reheat pipe.

[0015] In summary, this application includes at least one of the following beneficial technical effects:

[0016] This device replaces traditional high-speed stirring with a low-frequency vibration component. An electric vibrator and planetary gear drive system ensure uniform ink dispersion, preventing rheological degradation caused by high shear forces. A nylon damping disc further reduces the impact of mechanical vibration on the ink structure, ensuring stable particle suspension without damaging its physical properties. A nitrogen cylinder continuously fills the storage tank with nitrogen, replacing oxygen and effectively preventing ink surface crusting and abnormal viscosity increases, thus extending storage stability. An integrated refrigeration and heating unit, along with a return-temperature pipeline, evenly regulates the tank temperature, preventing ink stratification or component degradation due to temperature fluctuations. Additionally, a lifting component uses a hydraulic cylinder to adjust the height of the vibration mechanism, ensuring low-frequency vibration acts on ink at different levels, improving mixing uniformity.

[0032] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0033] This application discloses a storage device for a non-aqueous printing ink composition. (Refer to...) Figures 1 to 5The non-aqueous printing ink composition storage device includes a storage tank 1, a cooling and heating integrated unit 2, a return pipe 3, a nitrogen cylinder 4, a low-frequency vibration component 5, and a lifting component 6. The cooling and heating integrated unit 2 is located on the outside of the storage tank 1. The return pipe 3 is installed on the outside of the output end of the cooling and heating integrated unit 2, and the top of the return pipe 3 is tightly fitted to the inner surface of the storage tank 1. The nitrogen cylinder 4 is connected to the inner wall of the storage tank 1 through a gas pipe. The low-frequency vibration component 5 is movably connected to the middle of the storage tank 1. The lifting component 6 is installed above the low-frequency vibration component 5.

[0034] Storage tank 1 is used to seal and store non-aqueous printing inks to prevent external contamination. Cooling and heating unit 2 is used to precisely control the storage temperature to avoid high or low temperatures affecting the stability of the ink. Warm-up pipe 3 is used to transport hot and cold gases. Nitrogen cylinder 4 is used to fill the tank with nitrogen to replace oxygen. Low-frequency vibration component 5 vibrates storage tank 1 at a low frequency to gently disperse settled particles and avoid shear damage caused by high-speed stirring. Lifting component 6 is used to adjust the height of low-frequency vibration component 5 to adapt to different ink levels.

[0035] The low-frequency vibration assembly 5 includes a DC motor 51, an annular disk 52, a drive shaft 53, planetary gears 54, a nylon damping disk 55, and an electric vibrator 56. The DC motor 51 is movably connected to the top center of the storage tank 1. The drive shaft 53 passes through the inner wall of the top of the storage tank 1 and is fixedly connected to the motor shaft of the DC motor 51 via a coupling. The annular disk 52 is movably connected to the inside of the storage tank 1. The outer side of the planetary gears 54 is inserted into one side of the nylon damping disk 55. The electric vibrator 56 is inserted into the inner side of the middle of the nylon damping disk 55.

[0036] A main gear 7 is also fixedly connected to the side of the drive shaft 53 near the annular disk 52, and the external teeth of the main gear 7 mesh with the external teeth of the planetary gear 54.

[0037] The lifting assembly 6 includes a boss 61, a hydraulic cylinder 62, and a hollow support 63. The boss 61 is fixedly connected to the top of the storage tank 1. The hydraulic cylinder 62 is installed above the boss 61, and the output end of the hydraulic cylinder 62 is fixedly connected to the middle of the top of the hollow support 63. The bottom of the hollow support 63 is fixedly connected to the top surface of the annular disk 52.

[0038] The annular disk 52 is also equipped with an annular rack 8 that matches the external teeth of the planetary gear 54.

[0039] The inner side of the annular disk 52 is also rotatably connected to the limit frame 9, and the outer side of the limit frame 9 is rotatably connected to the inner side of the planetary gear 54.

[0040] An air pump 10 for supplying hot air into the storage tank 1 is also installed on the outside of the reheat pipe 3.

[0041] The usage process of the non-aqueous printing ink composition storage device according to the embodiments of this application is roughly as follows:

[0042] Open the sealing cap of storage tank 1, inject non-aqueous printing ink into the tank, and close the sealing cap to ensure that storage tank 1 is completely sealed to prevent external contaminants from entering. During temperature control, start the integrated cooling and heating unit 2, and supply temperature-regulating gas into storage tank 1 through the return pipe 3. The air pump 10 assists in gas circulation, so that the temperature inside the tank is quickly stabilized within the set range of 15-25℃. The return pipe 3 is tightly fitted to the inner wall of the tank to ensure uniform temperature distribution. During inert gas protection, open the valve of nitrogen cylinder 4 and fill storage tank 1 with nitrogen. Continue filling with nitrogen until the oxygen content inside the tank is below 1%, effectively inhibiting ink oxidation and curing. During vibration and anti-settling process, start the DC motor 51, which drives the main gear 7 to rotate through the drive shaft 53. The main gear 7 drives the planetary gear 54 to perform planetary motion along the ring rack 8. The planetary gear 54 drives the nylon damping disc 55 and the electric vibrator 56 to generate low-frequency vibration of 30-50Hz. The limit frame 9 ensures the stable running trajectory of the planetary gear 54. When the ink level changes, the hydraulic cylinder 62 is activated. The hydraulic cylinder 62 drives the annular disc 52 to rise and fall as a whole through the hollow bracket 63, so that the vibration component is always kept in the optimal working position, thereby extending the storage period and service life of the ink.

[0043] The beneficial technical effects of the non-aqueous printing ink composition storage device of this application embodiment are roughly as follows:

[0044] This device replaces traditional high-speed stirring with a low-frequency vibration component 5. An electric vibrating rod 56 and planetary gear 54 drive the system to uniformly disperse the ink, avoiding rheological degradation caused by high shear forces. A nylon damping disc 55 further reduces the impact of mechanical vibration on the ink structure, ensuring stable particle suspension without damaging its physical properties. A nitrogen cylinder 4 continuously fills the storage tank with nitrogen, replacing oxygen and effectively preventing skinning and abnormal viscosity increases on the ink surface, thus extending storage stability. A combined cooling and heating unit 2, along with a return-temperature pipe 3, evenly regulates the temperature inside the tank, preventing ink stratification or component degradation due to temperature fluctuations. Additionally, a lifting component 6 adjusts the height of the vibration mechanism via a hydraulic cylinder 62, ensuring low-frequency vibration acts on inks at different levels, improving mixing uniformity. A main gear 7, in conjunction with a ring rack 8, enhances the uniformity of vibration distribution, preventing ink deposition at the bottom of the tank.

[0045] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
