Description

Technical Field

[0001] The utility model belongs to the technical field of UV ink production, and in particular relates to a UV ink filtering and dispersing device. Background Art

[0002] UV ink is an ink that is cured by ultraviolet light. It has the advantages of fast drying, good wear resistance, bright colors, and environmental protection and pollution-free. It is widely used in printing, packaging, decoration, electronics and other fields.

[0003] During the production of UV ink, raw material mixing and dispersion steps are required. Specifically, photosensitive monomers, diluents, plasticizers, pigments, etc. are placed in a mixing barrel for mixing as needed to complete mixing and dispersion, and the semi-finished products are then sent to the subsequent grinding step. However, the production process of UV ink has high requirements, and the ink needs to be fully dispersed and filtered to ensure the quality and performance of the ink.

[0004] However, in the existing UV ink dispersion step, a stirring barrel with a diameter of no more than 1m is usually used for stirring to ensure the dispersion quality and avoid the problem of fine lumps. However, due to the long time of stirring and dispersing, if a larger stirring barrel is not used, the amount of ink stirred each time cannot meet the production requirements. If a larger stirring barrel is used, the stirring device cannot well meet the dispersion requirements of the ink, and the time of dispersion and stirring will be greatly prolonged. Some volatile raw materials will evaporate in this process, and the volatilization speed is closely related to environmental factors, which will cause uncontrollable changes in the formula and is inconsistent with the design.

[0005] At present, the existing technology adopts more methods to ensure the output by adding stirring and dispersing equipment. However, it does not meet the requirements of energy-saving production of enterprises. Therefore, it is necessary to propose a new device to solve the problem of insufficient dispersion of semi-finished ink products while ensuring the output. Utility Model Content

[0042] In order to make the purpose, technical solution and advantages of the implementation of the utility model clearer, the technical solution in the implementation of the utility model will be clearly and completely described below in conjunction with the drawings in the implementation of the utility model. The described implementation is a part of the implementation of the utility model, not all of the implementations.

[0043] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present invention.

[0044] Example 1

[0045] Please see attached Figure 1-2 The UV ink filtering and dispersing device of the utility model is mainly used to further filter and disperse the semi-finished UV ink after preliminary stirring and dispersion, effectively ensuring that the semi-finished ink reaches a sufficient dispersion degree, while reducing the time and dispersion degree requirements of the preliminary dispersion. The UV ink filtering and dispersing device of the utility model mainly includes a storage hopper 100, a filtering mechanism 200 and an ink dispersing mechanism 300.

[0046] Among them, the UV ink filtering and dispersing device of the utility model is arranged in the process between dispersion and grinding in the UV ink production process, and serves as a link between the dispersion process and the grinding process.

[0047] Specifically, the filtering mechanism 200 is used to filter the semi-finished UV ink product to remove large solid particles or insoluble impurities that are not fully dispersed in the previous dispersion process.

[0048] The ink dispersing mechanism 300 is used to further disperse and stir the semi-finished UV ink to improve the uniformity and stability of the ink. It is arranged in the middle of the storage hopper 100 to intercept the semi-finished UV ink filtered by the filtering mechanism 200 to prevent the semi-finished UV ink from flowing directly into the bottom of the storage hopper 100 without being dispersed.

[0049] Considering the permeability of the semi-finished UV ink product, the filtration mesh of the filtration mechanism 200 cannot be set too large. Therefore, after the preliminary filtration, there will still be certain small solid particles in the finished UV ink product, which can be dispersed by further dispersing and stirring.

[0050] The storage hopper 100 is used to store and transport the filtered and dispersed UV ink semi-finished product, and includes a feed port 110 and a discharge port 120 .

[0051] In order to ensure effective dispersion of the UV ink semi-finished product, the ink dispersion mechanism 300 includes a carrier plate 310 and a dispersion and stirring module 320 .

[0052] The carrier plate 310 is disposed in the middle section of the storage hopper 100 and below the filter mechanism 200 and has an overflow port 330. The overflow port 330 is used to provide a stable flow direction for the UV ink semi-finished product. In theory, all UV ink semi-finished products will pass through the overflow port 330 and enter the bottom of the storage hopper 100.

[0053] At the same time, the dispersion and stirring module 320 is disposed in the carrier plate 310 to further disperse the UV ink semi-finished product flowing through.

[0054] It can be understood that in order to prevent the semi-finished UV ink in the carrier plate 310 from mixing with the semi-finished UV ink in the filter mechanism 200 , the level of the overflow port 330 is lower than the bottom of the filter mechanism 200 .

[0055] The working principle of the UV ink filtering and dispersing device in this embodiment is as follows:

[0056] First, the UV ink semi-finished product that has been preliminarily stirred and dispersed is placed on the loading platform 600, and then added to the storage hopper 100 through the feed port 110. After passing through the feed port 110, the UV ink semi-finished product first enters the filtering mechanism 200, and is filtered through the filter screen 220 to remove impurities and large particles therein, thereby improving the purity of the ink. The filtered ink semi-finished product falls into the carrier plate 310 and is received by the dispersion and stirring module 320. The dispersion and stirring module 320 further disperses and stirs the ink semi-finished product to increase the uniformity and stability of the ink. This makes the subsequent grinding process more efficient. The dispersed and stirred ink semi-finished product flows out from the overflow port 330, enters the bottom of the storage hopper 100, and is then transported to the next process through the conduit.

[0057] In summary, the utility model has at least the following benefits:

[0058] 1. The utility model further filters and disperses the UV ink semi-finished product that has been initially stirred and dispersed by providing a filtering mechanism 200 and a dispersing mechanism, thereby effectively ensuring that the ink semi-finished product reaches a sufficient degree of dispersion, while reducing the duration of the initial dispersion and the dispersion requirements.

[0059] 2. Before the grinding process is set in the utility model, the flow rate of the process is relatively low, and in the low flow stage, it can effectively ensure that all semi-finished UV inks are fully dispersed and stirred.

[0060] Example 2

[0061] The difference between this embodiment and embodiment 1 is that this embodiment optimizes the specific structure of the device of the utility model, see Figure 4~Figure 8 .

[0062] In order to facilitate the fixing and installation of the device, this embodiment provides a UV ink filtering and dispersing device, and its structural schematic diagram is as follows: Figure 4 The device mainly comprises a storage hopper 100, a filtering mechanism 200, an ink dispersing mechanism 300 and a bracket 400.

[0063] Please continue to refer to 4 and Figure 5 , wherein the bracket 400 includes a top platform 410 and legs 420 connected to the platform, for supporting the storage hopper 100 and the filtering mechanism 200 .

[0064] The storage hopper 100 is funnel-shaped, and its upper part is sealed and connected to the top platform 410 of the bracket 400. The bottom is provided with a discharge port 120, which is connected to an external conduit for conveying the filtered and dispersed UV ink to the next process. The upper part of the storage hopper 100 is provided with a feed port 110, which is used to add the UV ink semi-finished product that has been preliminarily stirred and dispersed into the storage hopper 100. The storage hopper 100 is provided with an ink dispersion mechanism 300 inside, which is used to further disperse the UV ink semi-finished product.

[0065] The ink dispersing mechanism 300 is disposed in the middle section of the storage hopper 100 and below the filtering mechanism 200 to receive the semi-finished UV ink after filtering. The ink dispersing mechanism 300 includes a carrier plate 310 with an overflow port 330 and a dispersing and stirring module 320 disposed in the carrier plate 310. The carrier plate 310 is disposed below the filtering mechanism 200 to ensure that the semi-finished UV ink after filtering by the filtering mechanism 200 can be received.

[0066] For details, see Figure 6The carrier plate 310 includes a plate bottom 311 and a plate wall 312 arranged along the edge of the plate bottom 311. The top of the plate wall 312 is lower than the bottom of the filter mechanism 200 to prevent the ink level in the carrier plate 310 from being higher than the filter mechanism 200 and causing mixing. The overflow port 330 is arranged at the top of the plate wall 312. The overflow port 330 flows outward to the bottom of the storage hopper 100 and is used to transport the dispersed semi-finished ink to the bottom of the storage hopper 100. In order to fully stir and disperse the UV ink semi-finished product, the overflow port 330 is arranged downstream in the ink flow direction, and the dispersion and stirring module 320 is arranged midstream in the flow direction to ensure that all ink can pass through the dispersion and stirring module 320.

[0067] After the UV ink semi-finished product passes through the filtering mechanism 200, it will be temporarily gathered in the carrier plate 310. By controlling the flow rate and its own viscosity, the UV ink semi-finished product will be dispersed by the dispersion and stirring mechanism before filling the carrier plate 310. After filling the carrier plate 310, the filtering and dispersing device of the utility model will be in a state of dynamic equilibrium, that is, the UV ink semi-finished product that enters the carrier plate 310 later will push the UV ink semi-finished product that enters earlier to flow out from the overflow port 330 to the bottom of the storage hopper 100, such as Figure 6 Therefore, it can be ensured that most UV ink semi-finished products can be dispersed and stirred.

[0068] In addition, in order to facilitate cleaning of the equipment and empty the UV ink semi-finished product on the carrier plate 310, a drainage hole 340 is provided on the bottom surface of the carrier plate 310. The drainage hole 340 runs through the bottom of the carrier plate 310, and a rubber plug 500 is detachably installed thereon to control the discharge of ink.

[0069] The dispersion stirring module 320 includes a dispersion paddle 321 and a driving motor 322 for driving the dispersion paddle 321 to rotate. The dispersion paddle 321 is arranged in the carrier plate 310, and its rotation direction is opposite to the flow direction of the ink to increase the shear force of the ink and improve the dispersion effect. The driving motor 322 is connected to the dispersion paddle 321 in a transmission manner. Specifically, in this embodiment, the driving motor 322 is arranged on the top platform 410, and its rotor faces downward. At the same time, it is connected to the dispersion paddle in the carrier plate 310 through a transmission rod to drive the dispersion paddle to rotate. This arrangement can improve the transmission efficiency and prevent the driving motor 322 from affecting the storage hopper 100.

[0070] For filter mechanism 200, please refer to Figure 7 and Figure 8, installed at the feed inlet 110 of the storage hopper 100, for filtering the UV ink semi-finished product to remove impurities and large particles therein. The filter mechanism 200 includes a filter chamber 210 sleeved on the feed inlet 110 of the storage hopper 100 and a filter screen 220 arranged at the bottom of the filter chamber 210. The top edge of the filter chamber 210 is turned outward to be provided with a fixing groove 230, which overlaps with the edge of the bracket 400 to fix the filter mechanism 200. The filter mechanism 200 is a whole detachable solution, which is easy to clean and replace.

[0071] The advantages of this embodiment are as follows:

[0072] 1. This embodiment further filters and disperses the UV ink semi-finished product that has been preliminarily stirred and dispersed by providing a filtering mechanism 200 and an ink dispersing mechanism 300, thereby effectively ensuring that the ink semi-finished product reaches a sufficient degree of dispersion, while reducing the duration of the preliminary dispersion and the dispersion requirements.

[0073] 2. Before the grinding process is set in this embodiment, the flow rate of this process is relatively low. In the low flow stage, it can be effectively ensured that all semi-finished UV inks are fully dispersed and stirred.

[0074] 3. In this embodiment, the filter mechanism 200 is an integrally detachable solution, which is conducive to cleaning the filter mechanism 200 and improving production efficiency.

[0075] Embodiment 3:

[0076] The difference between this embodiment and embodiment 2 is that this embodiment optimizes the feeding structure of the device of the utility model, see Fig. 9 .

[0077] In this embodiment, a loading platform 600 is also provided on one side of the bracket 400. The loading platform 600 is arranged on the side of the feed port 110, and the horizontal height of the loading platform 600 is lower than the height of the top platform 410. It is used to place a mixing barrel 700 containing the preliminarily dispersed UV ink semi-finished product, so as to facilitate the addition of the UV ink semi-finished product to the feed port 110 and the connection of the process.

[0078] When loading materials, the discharge pipe (not shown) at the bottom of the mixing barrel 700 extends to the top of the filtering mechanism 200 to achieve loading of materials.
