Description

Technical Field

[0001] This utility model relates to the field of material supply, and in particular to ink or glue mixing systems and material supply systems. Background Technology

[0002] The formulation of fluids (such as inks and adhesives) directly affects the physical properties (such as viscosity, flowability, and adhesion) and chemical properties (such as curing speed and weather resistance) of products. For example, the composition ratio of printing inks determines color saturation, drying time, and compatibility with the substrate; the formulation of adhesives must balance bond strength and application efficiency. By precisely controlling the amount of solvent, the proportion of additives, or the content of hardener, it is possible to ensure that the fluid maintains stable performance under different process conditions (such as temperature, pressure, and speed), thereby meeting the needs of high-speed production, complex pattern printing, or high-strength bonding. Therefore, the formulation and continuous stable supply of fluids (such as inks and adhesives) are core elements in ensuring production efficiency and product quality. Utility Model Content

[0073] A large-scale printing system is an integrated device composed of multiple cooperating subsystems, mainly including a main control system (responsible for overall command interpretation and task scheduling), an ink supply system (ink storage and delivery), a printhead assembly (performing high-precision printing), a media delivery system (substrate positioning and transfer), a drying / curing system (for rapid setting of ink or adhesive), and a detection and feedback system (real-time monitoring of print quality). Among these, the ink mixing system, as the core module of the ink supply system, undertakes the crucial functions of fluid characteristic regulation and dynamic adaptive supply. Its role is to precisely adjust the component ratios (such as solvents, pigments, additives), viscosity, and temperature of ink / adhesive based on preset formulas or real-time feedback data, ensuring that fluid properties (such as flowability, adhesion, and drying rate) match printing speed, environmental conditions, and substrate characteristics. The ink mixing system is usually located upstream of the ink supply pipeline, and through closed-loop control linking the printhead and detection system, it directly determines the consistency of printed colors, coating uniformity, and the stability of continuous equipment operation.

[0074] The first embodiment of this application provides a feeding system, specifically for supplying ink to a large printing system or adhesive to other devices.

[0075] Specifically, such as Figure 1 As shown, the feeding system includes: a feeding tank 1, a viscosity controller 2, a feeding trough 3, and the aforementioned ink or glue mixing system 4. The feeding tank 1 is connected to the mixing tank 41 and can store the mixed material in the mixing tank 41. The viscosity controller 2 is connected to the feeding tank 1 and the feeding trough 3 respectively and is used to control the viscosity of the material in the feeding tank 1. The feeding trough 3 is used to supply material to external equipment.

[0076] Specifically, the ink or glue prepared by the film or glue dispensing system flows into the supply tank 1. Preferably, the fluid in the supply tank 1 flows into a viscosity controller, where the viscosity is adjusted. After passing through the viscosity controller, the fluid flows into the supply trough 3. The printing system or other equipment can then use the ink or glue in the supply trough 3 for printing or other operations.

[0077] Currently, some ink mixing processes rely heavily on manual operation. Operators need to manually weigh solvents, pigments, or adhesive base materials, adjust the proportions based on experience, and achieve mixing through simple stirring. As a result, the quality of the inks or adhesives mixed is relatively poor and cannot meet the requirements, and the demand for manual mixing personnel is also very high.

[0078] Therefore, this application provides an ink or glue mixing system 4, which can realize the automatic mixing of fluids such as ink or glue.

[0079] Specifically, such as Figure 1The ink or adhesive mixing system 4 includes: a mixing tank 41, a raw material tank 421, a raw material pump 423, a solvent tank 431, a solvent pump 433, a mixing weighing device 411, a raw material weighing device 4211, and a control system 45.

[0080] A weighing device 411 is installed at the bottom of the mixing container 41 and is used to weigh the mixing container 41 and the ink or glue inside it. Specifically, the weighing device 411 and the mixing container 41 are separable. The weighing device 411 is a base with a weighing function, such as a weighing scale. The mixing container 41 can be placed on the weighing device 411 or removed from it. The weighing device 411 can weigh the material in the mixing container 41 in real time, and the control system 45 communicates with the weighing device 411 to obtain the measurement data in real time. The control system 45 can determine the amount of material used in the mixing container 41 by using the data from the weighing device 411.

[0081] A raw material weighing device 4211 is installed at the bottom of the raw material container 421 and is used to weigh the raw material container 421 and the ink or glue inside it. Specifically, the raw material weighing device 4211 and the raw material container 421 are separable. The raw material weighing device 4211 is a base with a weighing function, such as a weighing scale. The raw material container 421 can be placed on the raw material weighing device 4211 or removed from it. The raw material weighing device 4211 can weigh the material inside the raw material container 421 in real time, and the control system 45 communicates with the raw material weighing device 4211 to obtain the measurement data in real time. The control system 45 can determine the amount of material used in the raw material container 421 by using the data from the raw material weighing device 4211.

[0082] In addition, the ink or glue dispensing system 4 also includes a solvent weighing device 4311. Similarly, the solvent weighing device 4311 is located at the bottom of the solvent container 431 and is used to weigh the solvent container 431 and the ink or glue inside it. Specifically, the solvent weighing device 4311 and the solvent container 431 are separable. The solvent weighing device 4311 is a base with a weighing function, such as a weighing scale. The solvent container 431 can be placed on or removed from the solvent weighing device 4311. The solvent weighing device 4311 can weigh the material inside the solvent container 431 in real time, and the control system 45 communicates with the solvent weighing device 4311 to obtain the measurement data in real time. The control system 45 can then determine the amount of material used in the solvent container 431 based on the data from the solvent weighing device 4311.

[0083] In an alternative technical solution, the ingredient weighing device 411 can be integrated into the bottom of the ingredient tank 41, and the raw material weighing device 4211 can also be integrated into the bottom of the raw material tank 421. At the same time, the solvent weighing device 4311 can also be integrated into the bottom of the solvent tank 431.

[0084] Additionally, the ink or glue mixing system 4 may also include a detection device, a stirring pump 441, and a raw material tank 421 for mixing ink or glue. The raw material tank 421 is used to hold raw materials, which can be ink or glue. The mixing tank 41 and the raw material tank 421 are connected by a raw material pipeline 422. The raw material pump 423 is located on the raw material pipeline 422, and the raw material pump 423 can input the ink or glue from the raw material tank 421 into the mixing tank 41.

[0085] Solvent tank 431 is used to hold solvent. Solvent tank 431 and mixing tank 41 are connected by solvent pipe 432. Solvent pump 433 is located on solvent pipe 432 and is used to transport the solvent in solvent tank 431 to mixing tank 41.

[0086] The detection device can be used to detect the delivery amount of raw materials and solvents. The control system 45 is connected to the detection device, the raw material pump 423, the solvent pump 433 and the stirring pump 441 respectively. After detecting the delivery amount of raw materials and solvents, the detection device sends the delivery amount to the control system 45. The control system 45 controls the delivery amount of raw materials and solvents by controlling the raw material pump 423 and the solvent pump 433.

[0087] The inlet and outlet of the mixing pipeline are both located inside the mixing tank 41, and the mixing pump 441 is located on the mixing pipeline 442, which is used to extract the ink or glue from the mixing tank 41 and re-input it into the mixing tank 41.

[0088] Since the raw materials and solvents are transported by pipelines and pumps in this embodiment, the transport volume is more controllable. Moreover, the transport volume can be precisely controlled by the raw material pump 423 and the solvent pump 433 through the control system 45. Therefore, it is more accurate and automated than manually weighing materials such as solvents, pigments or adhesive substrates.

[0089] Using a stirring pipeline and stirring pump 441 to mix raw materials and solvents has the following advantages:

[0090] In ink or adhesive mixing systems, the cleanliness, stability, and long-term reliability of the mixing process are crucial to the final product quality. The core difference between traditional mechanical mixing methods, such as paddles or magnetic stirrers, and pipeline circulation mixing lies in the fluid contact method and its impact on the process. Traditional paddles or magnetic stirrers require their mixing components, such as metal blades or magnetic rotors, to be continuously immersed in the fluid, rubbing against the fluid and the container's inner wall. Over time, this can easily lead to metal debris or coating peeling, especially when handling high-viscosity adhesives or inks containing abrasive particles. These impurities, once mixed into the fluid, directly affect printing quality, such as causing printhead clogging or surface defects. If the fluid contains solvents, acidic or alkaline components, or active additives, metal components may undergo chemical corrosion, further releasing contaminants; for example, iron ions in traditional paddles can cause ink discoloration.

[0091] In addition, the heat generated by mechanical stirring may interfere with fluid temperature control. At the same time, due to the complex geometry of traditional blades (such as helical blades) or the gaps of magnetic rotors, fluid, especially high-viscosity glue or curing ink, can easily remain. Manual disassembly and thorough cleaning are required, otherwise the residue will contaminate the next batch of solution.

[0092] Compared to traditional mixing methods, the circulating pipeline system integrates an automated cleaning program. It uses pumped detergent (such as deionized water or solvent) to circulate and flush the pipeline and mixing tank 41, removing residues without disassembly. This is particularly suitable for scenarios involving multiple formula changes. The smooth pipeline and streamlined design of the mixing tank 41 reduce residue, and the high-flow-rate flushing ensures no cross-contamination between batches. Furthermore, the mixing pipeline can be connected to an external heat exchanger for precise control of the fluid temperature.

[0093] More preferably, to reduce the contact between the fluid and the agitator pump 441, the agitator pump 441 can be a non-contact circulation pump, such as a magnetically driven circulation pump, a diaphragm pump, a sealed centrifugal pump, or a peristaltic pump. The impeller or diaphragm of the agitator pump 441 is isolated from the fluid, and the fluid flow is driven only through the pipeline, reducing mechanical wear debris.

[0094] The ink or glue mixing system 4 also includes a feeding pipe 461 and a control valve 462. The feeding pipe 461 is connected to the mixing pipe 442 and the feeding tank 1 respectively. The mixing pipe 442 can input the ink or glue in the mixing pipe 442 into the feeding tank 1. The control valve 462 is used to open or close the feeding pipe 461.

[0095] The feed hopper 1 is used to supply ink or glue to the feed tank 3. Printing machines and other equipment can use the ink or glue in the feed tank 3 for printing and other operations. The feeding system may also include a feed weighing device 11, which is located at the bottom of the feed hopper 1 and used to weigh the feed hopper 1 and the ink or glue inside it. The feed weighing device 11 can be a weighing scale, on which the feed hopper 1 is placed, and the control system 45 is also electrically connected to the feed weighing device 11.

[0096] The fluid in the mixing pipe 442 is transported to the feeding tank 1 via the feeding pipe 461. A control valve 462 controls the opening and closing of the feeding pipe 461, enabling automation and continuous production. The intelligent opening and closing of the control valve 462 achieves fully automated transport of the mixed fluid from the mixing pipe 442 to the feeding tank 1. The system can trigger the transport process based on the liquid level sensor signal in the feeding tank 3, completing material replenishment without manual intervention and ensuring uninterrupted operation of the printing equipment. For example, when the liquid level in the feeding tank 3 is below a threshold, the control system 45 automatically opens the control valve 462 and starts the mixing pump 441, achieving a continuous production mode of "mixing and supplying simultaneously."

[0097] To achieve better mixing, preferably, the inlet and outlet of the mixing pipe 442 are positioned far apart from each other. More preferably, the inlet of the mixing pipe 442 is located at the bottom of the mixing tank 41, while the outlet of the mixing pipe can be located at the opening of the mixing tank 41.

[0098] In addition, in order for the detection device to detect the flow meter 47, in one possible embodiment, the detection device includes two flow meters 47, both of which are connected to the control system 45. One flow meter 47 is installed on the solvent pipe 432 to measure the amount of ink or glue conveyed in the solvent pipe 432, and the other flow meter 47 is installed on the raw material pipe 422 to calculate the amount of ink or glue conveyed in the raw material pipe 422.

[0099] For example, flow meter 47 measures the volume of fluid flowing through the pipe per unit time (e.g., liters / minute) and obtains the cumulative delivery volume by combining the time integral. The total delivery volume = instantaneous flow rate of the flow meter × operating time. Flow meter 47 can be an ultrasonic flow meter, a Coriolis mass flow meter, a volumetric flow meter, or an electromagnetic flow meter.

[0100] In one embodiment, the detection device may also be a weight detector, which is placed on the bottom outside of the mixing tank 41 to measure the weight of the mixing tank 41 and the fluid inside it.

[0101] For example, the weight measuring instrument can be a scale placed under the mixing tank 41, on which the mixing tank 41 is placed. The weight measuring instrument is connected to the control system 45, which can control either the raw material pump 423 or the solvent pump 433 to start, measure the weight of the raw material or solvent entering the mixing tank 41, shut down the activated raw material pump 423 or solvent pump 433, and then start the other one. For example, the raw material pump 423 can be started first, and after ink or glue flows into the mixing tank 41, the weight of the raw material can be measured by the weight measuring instrument to obtain the amount of raw material delivered. The raw material pump 423 can be shut down, and then the solvent pump 433 can be started, and the weight of the solvent can be measured by the weight measuring instrument. Specifically, the weight of the mixing tank 41 can be measured first, and after the fluid is introduced, the weight of the fluid and the weight of the mixing tank 41 can be measured. The difference between the two weights can be used to obtain the weight of the fluid.

[0102] Of course, the ink or adhesive dispensing system 4 may also include a level gauge that is communicatively connected to the control system 45. The level gauge is installed inside the dispensing tank 41 and is used to detect the liquid level inside the dispensing tank 41. The level gauge can also be used as a detection device to detect the amount of raw material or solvent being delivered by means of changes in liquid level.

[0103] In addition, the ink or adhesive dispensing system 4 also includes an integrated bracket 481, on which the control system 45 is mounted. The raw material pump 423 and the stirring pump 441 are also mounted on the integrated bracket 481 and located below the control system 45. Preferably, the integrated bracket 481 has casters 482 at its bottom. Because the control system 45, the raw material pump 423, and the stirring pump 441 are integrated together and the casters 482 are provided at the bottom, it is convenient to move the control system 45 and other equipment, allowing it to be used in different ink or adhesive dispensing systems 4.

[0104] It should be noted that the feeding system in the embodiments of this application may also include the heat exchanger in the seventh and eighth embodiments below. The heat exchanger may be installed on any one of the pipes, such as the raw material pipe 422, the solvent pipe 432 or the stirring pipe 442, to control the temperature of the fluid in each pipe.

[0105] In addition, ink rubs against other equipment during transport, generating a significant amount of static electricity. This static electricity buildup can trigger a series of chain reactions during printing, storage, and use. Static electricity typically originates from the triboelectric effect when ink comes into contact with pipes, printheads, or substrates, and is particularly pronounced in low-humidity environments.

[0106] When ink carries static electricity, uneven surface charge distribution causes ink droplets to deviate from their intended paths during printing, resulting in blurred edges or fine star-shaped splatter. This phenomenon is particularly pronounced in high-speed digital printing, where electrostatic adsorption causes some ink droplets to prematurely adhere to the area around the nozzle, gradually accumulating to form hard crystals and eventually clogging the printhead. Simultaneously, the electrostatic attraction between charged ink and the substrate can disrupt the pre-defined ink layer distribution. For example, in printing on plastic films, static electricity can cause localized thickening of the ink film, while adjacent areas experience missed printing due to charge repulsion, creating visible mottled textures. During the drying stage, static electricity can also interfere with the normal evaporation of solvents in the ink. The microscopic electric field formed by the charge can alter the direction of solvent molecule movement, causing the surface to dry much faster than the inner layer, leading to wrinkling or cracking. For specialty inks containing metallic pigments, static electricity is more likely to cause the directional aggregation of conductive particles, resulting in a loss of uniform metallic luster on the printed surface. From a safety perspective, electrostatic discharge in solvent-based inks can ignite volatile organic compound vapors, especially in enclosed printing equipment, where the instantaneous release of charge can generate sparks that could cause a deflagration. During long-term storage, static electricity can also cause the resin components in the ink to adhere to the inner wall of the packaging container. After opening the container, stringing or clumping can be observed, which seriously affects the fluidity for reuse.

[0107] Therefore, to solve the problem of static electricity in the ink mentioned above, the second embodiment of this application also provides a liquid delivery tube 5, which can remove static electricity from the ink. One or more of the aforementioned raw material pipe 422, solvent pipe 432, and stirring pipe 442 can be transported using this liquid delivery tube 5. It should be emphasized that the liquid delivery tube 5 in this application can be used not only for transporting ink or adhesive, but also for transporting other fluids as needed.

[0108] Specifically, such as Figure 2 As shown, the infusion tube 5 includes an inner layer 51 and an outer layer 52. The inner layer 51 is a conductive layer used to transport fluid. The outer layer 52 covers the inner layer 51, which protects the inner layer 51 and also reinforces the infusion tube 5.

[0109] Since the inner layer 51 of the infusion tube 5 is a conductive layer, the static electricity in the ink can be carried away through this conductive layer. Moreover, since the conductive layer is in close contact with the fluid, the fluid and the conductive layer can be in full contact, and the static electricity in the fluid can be efficiently transferred out by the conductive layer.

[0110] In some solutions, static electricity is discharged by embedding copper wires in the inner wall of the pipe. However, the copper wires are easily coated by high-viscosity ink and become ineffective. Moreover, the presence of copper wires in the inner wall of the pipe can lead to particle accumulation and secondary contamination. In this application, the entire inner layer 51 is made into a conductive layer, thus solving the problems of particle accumulation and secondary contamination on the pipe wall.

[0111] In one possible implementation, the inner surface of the inner layer 51 is a smooth surface, specifically, it can be polished. Because the inner layer 51 has a smooth surface, it is possible to reduce ink or glue residue on the inner side of the tube wall.

[0112] More preferably, the inner layer 51 of the infusion tube 5 is a corrosion-resistant layer that can resist the erosion of ink or glue.

[0113] Specifically, in one embodiment, the inner layer 51 is composed of a conductive material and a corrosion-resistant material, with a thickness of 0.5–3.0 mm. Specifically, the inner layer 51 includes a conductive filler and a corrosion-resistant polymer matrix. The conductive filler is dispersed within the corrosion-resistant polymer matrix. The conductive material may include one or more of carbon nanotubes, graphene, or metal nanoparticles (such as silver or nickel), uniformly dispersed in the corrosion-resistant polymer matrix at a mass ratio of 5%–30%. The corrosion-resistant polymer matrix may be, for example, polyvinylidene fluoride (PVDF), polyether ether ketone (PEEK), or fluorinated ethylene propylene copolymer (FEP). The particle size of the conductive filler is controlled within 10–200 nm, and uniform dispersion is achieved through a twin-screw extrusion process to form a three-dimensional continuous conductive network. The inner surface of the inner layer 51 is precision polished, with a surface roughness Ra ≤ 0.2 μm, achieving mirror-level smoothness and significantly reducing fluid flow resistance and triboelectric charge generation.

[0114] The outer layer 52 can be an insulating layer, which can be made of polyurethane (PU) or thermoplastic elastomer (TPU) material. The thickness of the outer layer 52 is greater than that of the inner layer 51, and can be 1.0–5.0 mm thick, with a surface Shore hardness of 80A–95A. The outer layer 52 is co-extruded onto the outer surface of the inner layer 51 to form a dense insulating barrier, preventing interference from external environmental charges. The surface of the PU layer can be designed with corrugated or spiral raised structures to enhance the pipe's flexibility (bending radius up to 3 times the pipe diameter) and anti-kink performance.

[0115] The smooth inner surface of the inner conductive layer 51 is achieved through a two-step process: first, mirror polishing (Ra≤0.05μm) is performed on the inner wall of the mold using diamond tools, initially achieving an inner surface Ra≤0.3μm for the extruded tube; then, fluid polishing is performed using a suspension of micron-sized alumina particles, further reducing the surface roughness to below Ra≤0.2μm. This smooth surface reduces fluid boundary layer separation, allowing the ink or adhesive to flow in a laminar state within the tube (Reynolds number Re<2000), avoiding localized charge accumulation caused by turbulence. Compared to traditional embedded copper wire solutions, the circumferential conductive layer design ensures a seamless electrostatic discharge path, maintaining overall conductivity even if local conductive fillers are temporarily covered by high-viscosity ink through a three-dimensional conductive network.

[0116] In a preferred embodiment, the inner layer 51 employs a gradient composite structure: within a 0.1 mm thickness near the fluid contact surface, the concentration of conductive filler gradually increases to greater than or equal to 30%, forming a highly conductive surface; the filler concentration in the internal region gradually decreases to greater than or equal to 8%, balancing mechanical strength and cost. This design maintains low surface resistance while avoiding brittleness issues caused by excessive filler.

[0117] In another embodiment, the inner layer 51 further includes a metal substrate layer and a conductive thin film layer, the conductive thin film layer being located within the metal substrate layer 51. The conductive thin film layer can be a conductive ceramic coating, a conductive diamond thin film coating, a composite electroplating layer, or a chemically plated nickel-phosphorus alloy. The metal substrate layer can be a metal substrate layer such as stainless steel.

[0118] For example, inner layer 51 employs a composite structure of a metal substrate and a conductive ceramic coating. The metal substrate is Hastelloy C-276, and the conductive ceramic coating is fluorine-doped tin oxide (FTO). This structure is well-suited for highly corrosive adhesives, such as electronic encapsulation adhesives containing 30% nitric acid. Specifically, a 2μm thick FTO film is deposited on the inner surface of the metal substrate using magnetron sputtering, achieving a surface resistivity <500Ω / sq and a nitric acid corrosion resistance rating of ASTM G31 Level 10. After 1000 hours of continuous operation in a strong acid environment at 85℃ and pH=1, the inner surface maintains a smoothness of Ra=0.15μm, with a volume resistivity fluctuation of <5%.

[0119] This application's embodiments, through multi-layer composite structure design and precision surface processing, achieve proactive suppression of electrostatic hazards during ink or adhesive delivery, synergistic optimization of fluid delivery efficiency and pipeline durability. The combination of a smooth inner surface and a fully circumferential conductive layer fundamentally solves problems such as uneven electrostatic discharge, particle residue, and corrosion failure that occur when using copper wire in some solutions, providing an innovative solution for high-precision printing, electronic packaging, and chemical fluid control.

[0120] The third embodiment of this application also provides a storage bucket, such as Figures 3a to 4b As shown, the storage container includes a container body 61, a lid 62, and a conductive tube. Figure 4a and Figure 4bAs shown, the container 61 has an internal cavity for storing ink or glue, and its outer surface is covered with a smooth, non-stick coating. The lid 62 can be opened and closed to fit over the opening of the container 61. The lid 62 and the container 61 can be completely separated or connected by a hinge. The outer surface of the lid 62 is also covered with a smooth, non-stick coating. One end of a conductive tube passes through the container 61 or lid 62 and contacts the internal liquid, while the other end extends outside the container 61. The conductive material conducts static electricity from the liquid to an external grounding device. In this design, the non-stick coating significantly reduces residue adhesion, allowing for cleaning with just water. The conductive tube directly contacts the liquid to conduct static electricity, avoiding the risk of static buildup due to the insulating properties of the non-stick coating. This design is particularly suitable for storing flammable and explosive inks or glues.

[0121] One or more of the above-mentioned mixing tanks, mixing tanks and solvent tanks may adopt the above-mentioned storage tank structure.

[0122] In one embodiment, the smooth, non-stick coating is made of a fluoropolymer material, such as a polytetrafluoroethylene (PTFE) coating formed by plasma spraying, with a thickness controlled in the range of 50-200 μm and a surface roughness of less than 0.8 μm. The PTFE coating not only possesses superhydrophobicity and chemical corrosion resistance, but also maintains surface smoothness during long-term use.

[0123] In one embodiment, the smooth, non-stick coating can be made of polytetrafluoroethylene (PTFE), or alternatively, a perfluoroalkoxy resin (PFA) coating or a fluorinated ethylene propylene copolymer (FEP) coating. The PFA coating is formed via thermal spraying, with a thickness of 30-150 μm and a surface roughness Ra ≤ 1.0 μm. PFA retains the non-stick and corrosion-resistant properties of PTFE, but has a higher melting point (approximately 305-310℃), making it suitable for high-temperature adhesive storage. Furthermore, its transparency is superior to PTFE, facilitating observation of the liquid level within the container. The FEP coating is prepared using a fluidized bed dip coating process, with a thickness ranging from 80-250 μm and a surface hydrophobic angle reaching 115°. The FEP coating offers better flexibility and impact resistance, making it suitable for frequently opened and closed parts of the container lid (62), and it is less prone to cracking over long-term use.

[0124] Additionally, in one possible implementation, such as Figure 4a As shown, an inclined plate 63 can also be added inside the barrel 61. The inclined plate 63 extends outward from the bottom of the barrel towards the opening at a preset angle and is sealed to the bottom and side walls of the barrel by laser welding. The presence of the inclined plate 63 causes the liquid inside the barrel to concentrate in the outlet area when poured, reducing residue. This structure enables the rapid emptying of high-viscosity inks or adhesives.

[0125] At the same time, such as Figure 4a and Figure 4bAs shown, the barrel 61 is rectangular near the bottom to facilitate docking and fixing with conveying equipment, and the rectangular bottom 64 structure can be stably placed in narrow spaces.

[0126] The storage container is equipped with a pneumatic valve interface. After the pneumatic valve is connected to the infusion tube, the liquid flow can be controlled by air pressure. Because a pneumatic valve structure is used instead of an electric valve, it avoids the possibility of sparks generated by electric valves igniting ink or glue. In addition, the pneumatic valve is less likely to generate static electricity.

[0127] The storage bin in this embodiment comprehensively improves safety, ease of use, and system stability through multiple innovative designs. The ultra-smooth, non-stick PTFE coating on the surfaces of the bin body 61 and lid 62 significantly reduces ink or adhesive residue, requiring only water rinsing for efficient cleaning. This not only reduces the use of highly corrosive cleaning agents but also avoids chemical contamination problems. Simultaneously, the design of the conductive tube in direct contact with the liquid allows for the real-time discharge of static electricity accumulated inside the material, fundamentally eliminating the risk of electrostatic sparks in flammable and explosive environments and ensuring safety during storage and transportation.

[0128] In terms of structural optimization, the inclined plate 63 inside the barrel guides the liquid to flow towards the outlet in a concentrated manner. Combined with the rectangular barrel bottom design, this not only reduces the waste of high-viscosity materials (the residual amount can be as low as 2%), but also enhances the stability of the barrel body 61 in narrow spaces.

[0129] The aforementioned conductive tube can be the infusion tube in the above embodiments. As described in the above embodiments, the infusion tube can be used to transport liquids. Since the infusion tube has a conductive layer that is electrically connected to the liquid, it can discharge static electricity in the fluid. The infusion tube is also electrically connected to an external grounding device, so that the static electricity in the fluid can be transferred to the ground.

[0130] Additionally, it should be noted that one or more of the above-mentioned mixing tank, mixing tank and solvent tank may also adopt the storage tank structure in the above embodiments.

[0131] The fourth embodiment of this application also provides a feeding system, such as Figure 5 As shown, the feeding system includes: a feeding trough 9, a first storage bin 7, and a second storage bin 8. The first storage bin 7 stores material, which can be ink or glue; the second storage bin 8 stores material, which can also be ink or glue. The first storage bin 7 is used to feed material into the feeding trough 9; the second storage bin 8 is used to replace the first storage bin 7 to feed material into the feeding trough 9 under preset conditions.

[0132] In one possible embodiment, the feeding system may further include a viscosity controller 10, which is used to control the viscosity of the material. The viscosity controller 10 is connected to the feeding trough 9, and both the first storage tank 7 and the second storage tank 8 are connected to the viscosity controller 10. The viscosity controller 10 has a built-in liquid pump, thus enabling the pumping of fluid from the first storage tank 7 and the second storage tank 8 into the viscosity controller 10. Alternatively, if the viscosity controller 10 is not included, an additional liquid pump can be added to pump the fluid. The viscosity controller 10 can be a viscosity controller from the prior art, such as the viscosity controllers in patents JP2021030473A and JP6363571B2; therefore, the type of viscosity controller is not specified here.

[0133] After the fluid in the first storage tank 7 flows into the viscosity controller 10, the viscosity controller 10 adjusts the viscosity of the fluid before supplying it to the feed tank 9. Under certain preset conditions, the supply of fluid from the first storage tank 7 is stopped, and the second storage tank 8 is used for supplying fluid. The fluid in the second storage tank 8 is also input into the viscosity controller 10, and after viscosity adjustment by the viscosity controller 10, it is input into the feed tank 9. The printer or other equipment uses the fluid in the feed tank 9 for printing or other operations.

[0134] The material is supplied to the feeding trough 9 by using two buckets, the first storage bucket 7 and the second storage bucket 8, which can provide redundancy and backup. When one bucket needs cleaning or maintenance, the other bucket can take over immediately to ensure production continuity.

[0135] Meanwhile, in some possible implementations, the volume of either the first storage bin 7 or the second storage bin 8 is greater than the volume of the other, that is, one of the first storage bin 7 and the second storage bin 8 is a large bin and the other is a small bin.

[0136] The main reasons for setting up large and small barrels in the printing press system and being interchangeably connected to the viscosity controller 10 are as follows:

[0137] Firstly, it offers flexibility in terms of process. Large containers are used to store large quantities of ink to meet the needs of long-term continuous printing, while small containers are used for temporary mixing of special inks (such as color changes or viscosity adjustments). The two can be quickly switched, reducing downtime and adapting to multi-variety, small-batch production scenarios.

[0138] In addition, viscosity control can be optimized. Due to the small size of the smaller container and the shorter ink circulation path, it is easier to accurately control viscosity differences and eliminate air bubbles; the larger container is suitable for a stable supply of regular inks. By using them alternately, a balance can be struck between high-precision control (small container) and efficient supply (large container).

[0139] In summary, the combination design of large and small drums optimizes ink storage, circulation control, and system reliability, balancing production efficiency and printing quality while also meeting the technical requirements of anti-static systems.

[0140] Meanwhile, the feeding system also includes a switching valve 11, which is connected to the viscosity controller 10, the first storage tank 7, and the second storage tank 8, respectively. The switching valve 11 connects the viscosity controller 10 to the first storage tank 7 or to the second storage tank 8. The switching valve 11 allows for reversal, selecting whether the first storage tank 7 or the second storage tank 8 is connected to the viscosity controller 10. Specifically, the switching valve 11 can be a manual three-way valve or an electrically controlled three-way valve. If it is an electrically controlled three-way valve, it can be electrically connected to the control system, which controls the reversal of the valve.

[0141] In addition, the feeding system also includes a first agitator 12, which is disposed in the first storage tank 7 and is used to agitate the material in the first storage tank 7; in some embodiments, the feeding system also includes a second agitator 13, which is disposed in the second storage tank 8 and is used to agitate the material in the second storage tank 8.

[0142] The first agitator 12 and the second agitator 13 can be impeller agitators. Each agitator 12 and the second agitator 13 includes an impeller, a transmission shaft, and a motor. The impeller is coaxially and fixedly connected to the transmission shaft, and the output shaft of the motor is coaxially and fixedly connected to the transmission shaft. The impeller is located within the fluid, and the motor drives the impeller to rotate, thereby agitating the fluid.

[0143] Of course, it should be noted that either the first stirrer 12 or the second stirrer 13 can also adopt the above-mentioned stirring pipe and stirring pump scheme, that is, either the first stirrer 12 or the second stirrer 13 includes the above-mentioned stirring pipe and stirring pump. Since the specific scheme has been described in detail in the above paragraph, it will not be repeated here.

[0144] In addition, in some embodiments, the feeding system may also include a first weight measuring instrument 14 disposed on the bottom outer side of the first storage bin 7, while in some embodiments, the feeding system may also include a second weight measuring instrument disposed on the bottom outer side of the second storage bin 8.

[0145] In some embodiments, the feeding system further includes a first level gauge disposed in the first storage tank 7, which is used to measure the liquid level in the first storage tank 7. In some embodiments, the feeding system further includes a second level gauge disposed in the second storage tank 8, which is used to measure the liquid level in the second storage tank 8.

[0146] It should also be noted that the first storage bin 7 and the second storage bin 8 in this application can be the storage bins described above, but in some embodiments, the first storage bin 7 and the second storage bin 8 can also be ordinary storage bins.

[0147] Meanwhile, any one of the pipes connecting the first storage tank 7 and the viscosity controller 10, the second storage tank 8 and the viscosity controller 10, and the viscosity controller 10 and the feed tank 9 can be the infusion pipe in the above embodiment, or it can be an ordinary plastic pipe.

[0148] As can be seen from the above, since the feeding system in this embodiment adopts a feeding system with dual storage bins and pneumatic valve linkage, it can automatically switch to the spare bin when the main bin is exhausted, ensuring continuous operation of the production line and greatly reducing the downtime frequency caused by material replacement. The main bin can be the first storage bin 7 or the second storage bin 8, and the spare bin can be the second storage bin 8 or the first storage bin 7.

[0149] The embodiments of this application comprehensively improve the safety, ease of use, and system stability of the storage container through multiple innovative designs. The PTFE coating forms an ultra-smooth, non-stick layer on the surface of the container body and lid, significantly reducing ink or glue residue. Highly efficient cleaning can be achieved simply by rinsing with water, reducing the use of strong corrosive cleaning agents and avoiding chemical pollution problems. Simultaneously, the design of the infusion tube in direct contact with the liquid allows for the real-time discharge of static electricity accumulated inside the material, fundamentally eliminating the risk of electrostatic sparks in flammable and explosive environments and ensuring safety during storage and transportation.

[0150] In terms of structural optimization, the first storage tank 7 and the second storage tank 8 can adopt the above-mentioned storage tank. The storage tank is equipped with an inclined plate, which guides the liquid to flow to the outlet. Combined with the rectangular tank bottom design, it not only reduces the waste of high-viscosity materials (the residual amount can be as low as 2%), but also enhances the stability of the tank in narrow spaces.

[0151] The fifth embodiment of this application also provides a feeding system. The feeding system in this embodiment is basically the same in structure as the feeding system in the fourth embodiment. The main difference is that in the fifth embodiment, the feeding system also includes a control system, which is communicatively connected to the switching valve 11, for example, by wired or wireless connection.

[0152] The switching valve 11 is controlled by the control system. Specifically, the switching valve 11 can be a solenoid three-way valve or an electric three-way valve. The control system can control whether the viscosity controller 10 is connected to the first storage tank 7 or the second storage tank 8.

[0153] Additionally, it should be noted that in some embodiments, the control system may be the controller in the viscosity controller 10, or it may be a general control system.

[0154] In addition, such as Figure 6 As shown, the feeding system also includes a first weight measuring instrument 14 disposed on the outer bottom of the first storage bin 7, and the first weight measuring instrument 14 is communicatively connected to the control system. The feeding system also includes a second weight measuring instrument disposed on the outer bottom of the second storage bin 8, and the second weight measuring instrument is communicatively connected to the control system.

[0155] Most of the technical features in this embodiment are described in detail in the fourth embodiment, so they will not be repeated here.

[0156] The sixth embodiment of this application also provides an inkjet or glue nozzle assembly, such as... Figure 6 and Figure 7 As shown, the inkjet or glue nozzle assembly 15 is disposed on the side wall of the feed trough 9, such as... Figure 7 As shown, the inkjet or glue nozzle assembly 15 includes: a nozzle 150, an adapter 151, and a fixing member 152. The nozzle 150 is capable of spraying ink or glue into the feed trough 9. One end of the adapter 151 is connected to the nozzle 150, and the other end is connected to the feed tube. The fixing member 152 is connected to the adapter 151 and can be detachably fixed to the side wall of the feed trough 9. The adapter 151 is a two-way connector.

[0157] In some embodiments, one end of the adapter 151 is connected to the viscosity controller of the feeding system in the above embodiments via a pipe. Of course, in some embodiments, it can also be directly connected to the ink or glue storage tank. The glue or ink in the ink or glue storage tank flows into the feeding tank 9 through the inkjet or glue nozzle assembly 15. The external device then uses the ink or glue in the feeding tank 9 for printing or other operations.

[0158] In one possible implementation, such as Figure 8a As shown, the fixing member 152 can be a fixing clip 153, which can clamp the inkjet or glue nozzle assembly 15 to the side wall of the feed trough 9.

[0159] In another possible implementation, such as Figure 8b As shown, the fastener 152 may include a connecting part and a magnet 154. The connecting part is fixedly connected to the adapter 151, and the magnet 154 is disposed on the connecting part. The magnet 154 can magnetically attract the side wall of the feeding trough 9.

[0160] In yet another possible implementation, such as Figure 8cAs shown, the fixing member 152 includes a fixing frame 155 and a screw 156. The fixing frame 155 has a groove that can be inserted into the side wall of the feeding trough 9. The screw 156 passes through the side wall of the fixing frame 155 and is inserted into the groove. The screw 156 is threadedly connected to the side wall of the fixing frame 155. After the fixing frame 155 is engaged in the side wall of the feeding trough 9, the screw 156 is rotated, thereby pushing the screw 156 forward and pressing it against the side wall of the feeding trough 9, thus fixing the fixing member 152 to the side wall of the feeding trough 9.

[0161] In yet another possible implementation, such as Figure 8d As shown, the fixing member 152 includes a fixing plate 157, a support plate 158 and a linkage member 159. The fixing plate 157 and the linkage member 159 are disposed opposite each other on both sides of the side wall of the feeding trough 9, while the support plate 158 is disposed between the fixing plate 157 and the linkage member 159.

[0162] The support plate 158 is fixedly connected to the fixed plate 157 and hinged to the linkage 159. When the linkage 159 rotates relative to the support plate 158 toward the fixed plate 157, it can press against the side wall of the feeding trough 9.

[0163] Specifically, the linkage 159 includes: a handle 1591, a drive rod 1592, a connecting rod 1593, and a holding rod 1594. The drive rod 1592 is located below the handle 1591, and both the drive rod 1592 and the handle 1591 are hinged to the support plate 158. The connecting rod 1593 is located between the handle 1591 and the drive rod 1592, and both ends of the connecting rod 1593 in the length direction are hinged to the handle 1591 and the drive rod 1592, respectively. The feeding system holding rod 1594 is fixedly connected to the end of the feeding system drive rod 1592 away from the feeding system support plate 158, and is used to press against the side wall of the feeding system feeding trough 9.

[0164] When handle 1591 is pressed down, handle 1591 pushes drive rod 1592 to rotate towards fixed plate 157 via connecting rod 1593. Since drive rod 1592 is also hinged to support plate 158, drive rod 1592 can rotate relative to support plate 158 towards fixed plate 157, thereby pressing against the side wall of feed trough 9. At this time, the entire inkjet or glue nozzle assembly 15 is fixed to the side wall of feed trough 9. Conversely, when handle 1591 is lifted up, handle 1591 drives drive rod 1592 to rotate away from fixed plate 157 via connecting rod 1593, thereby releasing the side wall of feed trough 9.

[0165] It should be noted that the support plate 158 is divided into two plates, which are respectively positioned opposite to and separated from the first plate and the second plate. The handle 1591 and the drive plate are hinged between the first plate and the second plate.

[0166] The seventh embodiment of this application also provides a feeding system, such as Figure 9 As shown, the feeding system 20 includes: a feeding tank 23, a viscosity controller, a feeding trough 24, and the inkjet or glue nozzle assembly described in the sixth embodiment above. The feeding tank 23 is used to hold ink or glue, and the viscosity controller is connected to the feeding tank 23 via a first pipe 21. The feeding trough 24 is connected to the viscosity controller via a second pipe 22. The feeding trough 24 is used to supply ink or glue to external devices. To maintain the balance of ink or glue in the feeding trough 24, the ink or glue in the feeding trough 24 can also flow back into the feeding tank 23.

[0167] It should be noted that the feeding system 20 may also include a heat exchanger in the seventh and eighth embodiments described below, the heat exchanger being disposed on the first pipe 21 or the second pipe 22.

[0168] Specifically, the feed trough 24 includes: a trough body 241, a partition plate 242, and a return port 243. The trough body 241 has a receiving cavity that can be used to hold ink or glue. The partition plate 242 is disposed inside the trough body 241 and is located near the inkjet or glue nozzle assembly. The return port 243 is disposed on the side wall of the trough body 241. The ink or glue in the receiving cavity flows back to the feed hopper 23 through the return port 243.

[0169] The inkjet or glue nozzle assembly has a nozzle outlet, and the nozzle outlet and return port 243 are respectively located on both sides of the isolation plate 242. As shown in the figure, the length of the nozzle needs to be increased. When the inkjet or glue nozzle assembly is fixed to the side wall of the feed trough 24, for example, if the side wall for fixing the inkjet or glue nozzle assembly is set as the first wall 244, then the nozzle length is greater than the distance between the isolation plate 242 and the first wall 244. In this way, the nozzle outlet can be located on the side of the isolation plate 242 away from the first wall 244, and a return channel is formed between the isolation plate 242 and the first wall 244, and the return port 243 is also located on the first wall 244.

[0170] In the feeding system 20, the first pipe 21 and the second pipe 22 can be ordinary pipes or the infusion pipes in the second embodiment described above.

[0171] The ink or adhesive uses a circulation system, i.e., from supply tank 23 → viscosity controller → supply tank 24 → supply tank 23. This circulation method is primarily for the following key reasons: 1. Ensuring viscosity uniformity: The ink in supply tank 23 may have uneven viscosity due to component stratification, temperature differences, or localized sedimentation. Therefore, through continuous circulation, the viscosity controller can repeatedly adjust the ink, eliminating localized differences. This effect is similar to "stirring," making the ink viscosity uniform throughout the system. For example, in large printing presses, a single adjustment may result in inconsistent color depth during printing. 2. Maintaining dynamic stability: The supply tank 24 acts as a buffer container, directly and stably supplying ink to the print head or spraying equipment, avoiding flow fluctuations. During circulation, the liquid level and pressure in the supply tank 24 remain constant, ensuring continuous production. 3. Real-time feedback and closed-loop control: The viscosity controller continuously monitors the ink viscosity, forming a closed-loop feedback system. If a deviation is detected (such as increased viscosity due to solvent evaporation), thinner is automatically added immediately and the mixture is remixed. Compared to single adjustments, the above-mentioned circulation method allows the circulation system to cope with dynamic changes (such as temperature fluctuations and changes in production speed). 4. Preventing sedimentation and component separation: During the circulation process, some inks contain particles (such as metallic pigments) or high-density components, which are prone to sedimentation when left to stand. The circulating flow generates shear force through pipes and pumps to prevent particles from settling or clumping.

[0172] The eighth embodiment of this application also provides a heat exchanger, such as Figures 10a to 10b As shown, the heat exchanger 25 includes a heat exchange tank 251 and fluid pipes 254. The heat exchange tank 251 has a square structure with an internal cavity 2511 for containing the heat exchange fluid. The square structure of the heat exchange tank 251 maximizes internal space utilization, facilitates the uniform arrangement of the fluid pipes 254, and saves space. The heat exchange tank 251 has an inlet and an outlet for the flow of the heat exchange fluid, facilitating fluid replacement and circulation. The heat exchange fluid can be cooling water, silicone oil, ethylene glycol aqueous solution, fluorinated liquid, etc. Connectors are provided at both the inlet and outlet of the heat exchange tank 251 for easy connection to external pipelines.

[0173] A fluid pipe 254 is provided inside the heat exchange tank 251. Preferably, the fluid pipe 254 is coiled inside the heat exchange tank 251. The fluid pipe 254 has an inlet 255 and an outlet 256, both of which are located outside the heat exchange tank 251 for easy connection to an external fluid circuit. Connectors are also provided on the inlet 255 and outlet 256 of the fluid pipe 254 to facilitate connection to external pipelines.

[0174] The fluid pipe 254 is used to transport the liquid to be heat exchanged, which can be a high-viscosity medium such as ink or glue. It should be noted that the temperature of the heat exchange fluid can be higher or lower than the temperature of the liquid to be heat exchanged. Therefore, the heat exchange fluid can be used to cool or heat the liquid to be heat exchanged, thereby controlling the temperature of the liquid to be heat exchanged within a suitable range.

[0175] In this embodiment, the heat exchange tank 251 contains the heat exchange fluid, while the fluid pipe 254 carries the fluid to be exchanged (such as ink, glue, or other high-viscosity media). Compared to some technologies where "the heat exchange tank 251 contains the fluid to be exchanged, and the fluid pipe 254 contains the heat exchange fluid," the design of the fluid to be exchanged (such as ink or glue) flowing within the long, thin, coiled fluid pipe 254 means that the pipe length is directly related to the heat exchange time. By rationally designing the total pipe length, it is possible to ensure that the medium remains in the pipe for a sufficient time to complete the heat exchange, while avoiding a sudden increase in flow resistance due to excessive pipe length.

[0176] From a system co-design perspective, this scheme fully utilizes the spatial advantages of the square heat exchange tank 251, maximizing the heat transfer area through a densely coiled fluid pipe layout 254, while maintaining smooth flow channels to reduce pressure loss at bends. The high-viscosity medium is enclosed in independent pipes, resulting in a smaller total load and controllable flow rate. This reduces pumping energy consumption (compared to the high-power pumps required for circulating high-viscosity media within the tank in traditional schemes) and shortens the system's thermal inertia, enabling rapid response to process temperature changes (such as instantaneous temperature adjustment in printing presses). Furthermore, when the heat exchange fluid circulates in a large volume within the tank, its low viscosity and good fluidity allow for stable temperature control via external thermostats, forming an efficient heat buffer pool and further ensuring heat transfer stability.

[0177] Furthermore, this design offers significant advantages in maintainability and anti-fouling capabilities. High-viscosity media are prone to deposits or scale buildup during long-term operation. Confining these within independent pipes allows for direct disassembly and cleaning, or replacement of specific pipe sections, avoiding the overall contamination and cleaning difficulties caused by high-viscosity media contacting the tank in traditional solutions. Combined with straight pipes or large-curvature coils of suitable diameter, the efficiency of mechanical flushing or chemical cleaning is greatly improved, reducing downtime for maintenance. In contrast, traditional solutions require frequent emptying of the high-viscosity media from the tank and cleaning of complex flow channels, resulting in high operating costs and potentially affecting the heat transfer performance of the heat exchange fluid pipelines due to residues.

[0178] In summary, this design achieves efficient heat exchange of high-viscosity media by precisely matching pipe length, diameter, and fluid characteristics, while reducing pressure drop and energy consumption. It is particularly suitable for scenarios requiring precise temperature control or frequent media replacement (such as multi-color printing and electronic bonding). Its structural innovation not only solves the efficiency bottleneck caused by the contradiction between fluid characteristics and heat transfer paths in traditional solutions, but also improves the reliability and maintainability of the system through modular design.

[0179] Furthermore, preferably, to accommodate fluids of different viscosities, the diameter of the fluid pipe 254 is proportional to the viscosity of the fluid, thereby ensuring smooth liquid flow and avoiding blockages or uneven flow rates. For example, some fluid pipes 254 may have a diameter of 16 mm, some may have a diameter of 20 mm, or the diameter of the fluid pipe 254 may be any number between 10 and 25 mm.

[0180] like Figure 10b As shown, the fluid tube 254 is spirally coiled inside the heat exchange tank 251. The coiled structure allows for a longer flow path of the liquid inside the tube, resulting in sufficient heat exchange time and enhanced heat exchange efficiency. Simultaneously, a certain distance is reserved between the fluid tube 254 and the inner wall of the heat exchange tank 251, forming an annular space between the fluid tube 254 and the tank body. This allows the heat exchange liquid to fully surround the fluid tube 254, improving heat exchange efficiency.

[0181] In terms of structural layout, the inlet and outlet of the heat exchange tank 251 can be located on the same side wall, and the liquid inlet 255 and liquid outlet 256 can also be located on the same side wall. This arrangement facilitates unified management and installation, and the inlets and outlets can also be distributed on different side walls according to actual needs to adapt to specific scenario requirements.

[0182] The heat exchange tank 251 includes a pair of first sidewalls 2512 and a pair of second sidewalls 2513. The two pairs of sidewalls are arranged opposite each other and connected end to end to form the side frame of the heat exchange tank 251. A bottom plate 2514 and a top plate 2515 are provided at the bottom and top, respectively, forming a sealed internal cavity for holding the heat exchange fluid. The width of the first sidewall 2512 is greater than that of the second sidewall 2513. The inlet, outlet, liquid inlet 255, and liquid outlet 256 of the heat exchange tank 251 are all located on the second sidewall 2513, which allows for a more compact fluid connection and facilitates pipe laying.

[0183] The outlet and inlet 255 of the heat exchange tank 251 are respectively located on opposite sides of the heat exchange tank 251. That is, the inlet and outlet of the heat exchange tank 251 are located on the same second side wall 2513, while the inlet 255 and outlet 256 are located on another second side wall 2513.

[0184] To maintain the stability of fluid tube 254, such as Figure 11As shown, a support frame 257 is installed inside the heat exchange tank 251. Multiple support grooves 2570 are sequentially arranged on the support frame 257 along the spiral direction of the fluid pipe 254, in which the fluid pipe 254 is held in place, preventing the pipe from sagging or twisting due to gravity or liquid flow. The support frame 257 includes a support body 2571 installed on the inner wall of the heat exchange tank 251 and multiple support rods 2572. The support rods 2572 are sequentially arranged along the spiral direction, with adjacent support rods 2572 spaced apart to form support grooves 2570, ensuring that the fluid pipe 254 is evenly stressed.

[0185] Preferably, the heat exchanger 25 is provided with two support frames 257, which are located on both sides of the fluid pipe 254, to enhance the overall support and structural stability.

[0186] In addition, to facilitate equipment movement and protect the heat exchange structure, such as Figures 12a to 12c As shown, the heat exchanger 25 is equipped with an outer frame 258. The outer frame 258 is installed on the outside of the heat exchange tank 251, providing overall support. The outer frame 258 consists of multiple first square frames 2581 arranged sequentially along the width direction of the tank and multiple second square frames 2582 arranged sequentially along the height direction of the tank. The two are intersected and fixed to form a sturdy and stable frame structure. At the top of the outer frame 258, handles 2583 extend from two spaced-apart first square frames 2581, facilitating manual handling and installation.

[0187] In another possible embodiment, the fluid tube 254 described above can also be the infusion tube in the second embodiment. Of course, in some embodiments, the fluid tube 254 can also be a common plastic tube.

[0188] The ninth embodiment of this application also provides a heat exchanger, such as Figures 13 to 14 As shown, the heat exchanger 26 mainly comprises two parts: a heat exchange tank 261 and a fluid pipe 263. The heat exchange tank 261 has a hollow structure, with an internal cavity 262 for containing the heat exchange fluid. An inlet and an outlet are provided on the outer wall of the heat exchange tank 261 to facilitate the flow of the heat exchange fluid, allowing for its replacement and circulation, thereby improving heat exchange efficiency. Preferably, the outlet and inlet of the heat exchange tank 261 are positioned opposite each other on both sides of the heat exchange tank 261 along its height.

[0189] A fluid pipe 263 is installed inside the heat exchange tank 261 for conveying the heat exchange fluid, which can be a high-viscosity medium such as ink or glue. The fluid pipe 263 has an inlet 2631 and an outlet 2632, both of which are located outside the heat exchange tank 261 for easy connection to an external liquid delivery system to realize the input and output of the heat exchange fluid.

[0190] Since the heat exchange fluid (such as ink or glue) flows within the long, thin, coiled fluid tube 263, it is understood that the tube length is directly related to the heat exchange time. By rationally designing the total length of the tube, it is possible to ensure that the medium remains within the tube for a sufficient time to complete the heat exchange, while avoiding a sudden increase in flow resistance due to excessive tube length. Furthermore, the structure in this embodiment ensures that the heat exchange fluid flows within the closed fluid tube 263, preventing contamination and leakage, and guaranteeing the safety and cleanliness of the fluid heat transfer process.

[0191] Other advantages are described in the eighth embodiment, and will not be repeated in this embodiment to avoid repetition.

[0192] Preferably, the heat exchange tank 261 has a cylindrical shape, which, compared to a square shape, results in more uniform stress distribution in the circumferential direction. This effectively improves the pressure resistance and structural stability of the heat exchange tank 261, reduces the risk of thermal deformation, and extends the service life of the equipment.

[0193] Preferably, the bottom plate 268 and top plate 267 of the heat exchange tank 261 are arc plates that are connected to the cylindrical side frame of the heat exchange tank 261 by an arc. Because the connection is by an arc, there are no sharp angles, the force at the connection is even, and it is not easy to deform.

[0194] In one possible implementation, the heat exchange tank 261 includes: a cylindrical frame 266, a top plate 267 and a bottom plate 268. The cylindrical frame 266 is cylindrical, and the top plate 267 is disposed opposite to each other on both sides of the cylindrical frame 266 along the height direction of the cylindrical frame 266.

[0195] Among them, such as Figure 14 As shown, the top plate 267 and the cylindrical frame 266 are connected by an arc transition, and the bottom plate 268 and the cylindrical frame 266 are also connected by an arc transition.

[0196] In some embodiments, the top plate 267, the bottom plate 268, and the cylindrical frame 266 can be integrally formed or welded in a circular arc.

[0197] Since the top plate 267 and the bottom plate 268 are both arc plates and are connected to the cylindrical frame 266 by arc transitions, the entire heat exchange tank 261 is uniformly arc-shaped without any very sharp corners. Therefore, when the pressure inside the heat exchange tank 261 increases, the force is uniform in all directions, which can prevent the local pressure on the heat exchange tank 261 from being too high and causing damage to the heat exchange tank 261.

[0198] In another possible implementation, the diameter of the fluid pipe 263 is designed to be proportional to the viscosity of the heat exchange fluid, adapting to different fluid characteristics, such as high-viscosity media like ink and glue, effectively ensuring flow rate and heat exchange efficiency, and preventing blockage or low heat exchange efficiency caused by mismatched pipe diameter.

[0199] Preferably, the fluid pipe 263 has a spiral coiled structure, which extends the path of the fluid within the heat exchange tank 261, thereby increasing the contact area with the heat exchange fluid and improving heat exchange efficiency. Depending on actual needs, the fluid pipe 263 can maintain a preset distance from the inner wall of the heat exchange tank 261, allowing the heat exchange fluid to fully fill the space between the fluid pipe 263 and the inner wall, thus providing a stable and uniform heat transfer environment. Alternatively, the fluid pipe 263 can be installed close to the inner wall of the heat exchange tank 261, with the tank wall supporting the pipe, simplifying the support structure and facilitating processing and installation.

[0200] Regarding the arrangement of the inlet 2631 and outlet 2632, the inlet 2631 and outlet 2632 are arranged opposite each other on both sides of the heat exchange tank 261 along the height direction. More preferably, the inlet 2631 and outlet 2632 are arranged on the axis along the height direction of the heat exchanger 26, thereby ensuring uniform flow of fluid in the pipe, avoiding local heat accumulation or cold zones, and improving heat exchange uniformity.

[0201] To improve the overall stability and mobility of the equipment, such as Figure 15a and Figure 15b As shown, this embodiment also includes an outer frame 269 structure. The heat exchange tank 261 is mounted on the outer frame 269, and the bottom of the outer frame 269 is equipped with casters to facilitate the movement, arrangement, and maintenance of the entire equipment. This structural design ensures the structural stability of the equipment during use while enhancing its flexibility and convenience in actual production or experimental environments.

[0202] In another possible embodiment, the fluid tube 263 may also be the infusion tube in the second embodiment. Of course, in some embodiments, the fluid tube 263 may also be a common plastic tube.

[0203] In addition, it should be emphasized that, as needed, the heat exchanger 26 in the eighth and ninth embodiments can be applied to any of the above embodiments. Specifically, it can be installed in any pipe or pipeline and can be used to control the temperature of the ink or glue in each pipe, and to heat or cool the ink or glue.

[0204] This application provides a pipeline cleaning device and its application in ink or glue mixing systems and material supply systems. It can realize efficient, convenient and highly automated pipeline cleaning, raw material preparation and temperature control processes, and is suitable for cleaning and conveying processes of viscous liquids such as ink and glue in industrial preparation processes.

[0205] The tenth embodiment of this application provides a pipeline cleaning device, such as... Figure 16 and Figure 17aAs shown, the pipeline cleaning equipment includes a washing tank, an inlet pipe 272, an outlet pipe 273, and an air pipe 274. The washing tank is a sealed container used to hold detergent. In some embodiments, the detergent may be a mixture of water and lipid solvents, such as ethyl acetate, which has good detergency. Of course, in other embodiments, the detergent may be other liquids capable of removing dirt.

[0206] like Figure 16 and Figure 17a As shown, the washing tub includes a tub body 2711 and a tub lid 2712. The tub body 2711 has a cavity for holding detergent, and the tub lid 2712 is closable and can be placed over the tub body 2711. The washing tub has multiple interfaces for installing an inlet pipe 272, an outlet pipe 273, and an air pipe 274. These pipes are inserted into the tub and fixed to the tub lid 2712 or the tub body 2711. In some embodiments, the pipes can be located on the tub lid 2712, which facilitates replacement or maintenance while ensuring the structural integrity and pressure resistance of the tub body 2711. Of course, in some embodiments, the pipes can also be fixed to the tub body 2711. The closable design of the tub lid 2712 facilitates detergent addition and maintenance.

[0207] like Figure 17a As shown, both the inlet pipe 272 and the outlet pipe 273 are long pipes, inserted into the washing tub along its height. However, in some embodiments, they may not be inserted along the height, such as at an angle. The inlet pipe 272 has a first inlet 2721 and a first outlet 2722 along its length. The first inlet 2721 is located inside the washing tub, preferably near the bottom. The first outlet 2722 is located outside the washing tub and can be connected to one end of the pipe to be cleaned. The outlet pipe 273 has a second inlet 2731 and a second outlet 2732 along its length. The second inlet 2731 is located outside the washing tub and connected to the other end of the pipe to be cleaned. The second outlet 2732 is located inside the washing tub, preferably near the bottom.

[0208] The inlet pipe 272 and outlet pipe 273 are fixed to the washing tub. The two ends of the inlet pipe 272 and outlet pipe 273 exposed outside the washing tub are respectively connected to the two ends of the pipe to be cleaned, thus forming a closed flow channel. During cleaning, the detergent enters the inlet pipe 272 from the first inlet 2721 under the action of pressure difference, enters the pipe to be cleaned from the first outlet 2722, flows through the entire pipe to be cleaned, and then flows back to the second inlet 2731. After entering the outlet pipe 273 through the second inlet 2731, it flows back to the washing tub through the second outlet 2732, carrying away the residue adhering to the pipe wall.

[0209] In addition, the air duct 274 has an inlet end and an outlet end. The inlet end is located outside the washing tub and connected to the air source, while the outlet end is inserted into the washing tub and into the pipe at one end of the inlet duct 272 inside the washing tub, that is, into the first inlet 2721.

[0210] Introducing air bubbles during pipe cleaning enhances the cleaning effect. Specifically, the movement of air bubbles in the liquid disrupts laminar flow, increasing turbulence. This turbulence intensifies the contact between the solvent and the pipe wall, significantly increasing the scouring force and thus more effectively removing ink residue. Simultaneously, the bursting of air bubbles generates localized high-pressure micro-jet streams and shock waves. This mechanical action directly impacts the ink residue adhering to the pipe wall, loosening or detaching it from the surface, especially effective in narrow or complex pipe structures. Furthermore, the inclusion of air bubbles expands the contact area between the solvent and ink, promoting solvent penetration into the residue. The movement of air bubbles also accelerates the mixing of solvent and ink, enhancing dissolution efficiency.

[0211] Specifically, such as Figure 17b As shown, the air conduit 274 includes an air pipe 275, an elbow 276, and an inlet pipe 277. The air pipe 275 is a long pipe installed on the washing tub, which can be installed on the tub lid 2712. One end of the air pipe 275 is exposed outside the washing tub, while the other end is inserted into the washing tub. The elbow 276 connects the air pipe 275 and the inlet pipe 277. The inlet pipe 277 is directly inserted into the inlet pipe 272, specifically into the first inlet 2721. Because the air pipe 275 is inserted into the inlet pipe 272, air can be directly injected into the detergent flow channel, forming a gas-liquid mixture. After the air bubbles enter the pipe, they will enhance the fluid turbulence and release micro-jet streams and local shock waves during the bursting process, thereby significantly improving the cleaning efficiency.

[0212] The air pressure inside the air duct 274 is controlled between 0.6 and 1.0 MPa, ensuring the turbulent effect of the bubbles without damaging the duct structure. This bubble-assisted cleaning method effectively removes ink residue and other difficult-to-dissolve impurities from the inner wall of the duct, and is particularly suitable for complex or narrow duct structures.

[0213] In a preferred embodiment, the pipe cleaning equipment also includes a washing pipe 278, which can be optionally installed on the lid 2712 or the body 2711 and inserted into the washing tank. This washing pipe 278 is used to replenish external detergent into the tank to maintain solvent concentration or achieve multi-stage cleaning. Of course, in some embodiments, the washing pipe 278 may not be necessary; instead, detergent may be prepared manually and poured into the washing tank.

[0214] In certain operating conditions, to improve equipment efficiency and production line compatibility, pipeline cleaning equipment can be designed with a dual-channel structure, i.e., two inlet pipes 272 and two outlet pipes 273. Each set of inlet and outlet pipes connects to a section of the pipeline to be cleaned, allowing for parallel cleaning of two production pipelines simultaneously. For example... Figure 17c As shown, there are also two air ducts 274, which correspond one-to-one with the inlet duct 272 to ensure that each cleaning circuit has a bubble enhancement function.

[0215] To unify the gas supply, such as Figure 17c As shown, the outer ends of the two air pipes 274 are connected to a connecting pipe 279, which has an air inlet 2791. In this way, only one air source device is needed to supply air to both cleaning paths simultaneously, simplifying the pipeline layout and control logic.

[0216] Furthermore, it should be emphasized that, depending on the needs, the pipeline cleaning equipment in the tenth embodiment can be applied to any of the above embodiments. Specifically, it can be installed in any pipeline or conduit to clean that pipeline, for example, by connecting it to any one or more of the first pipeline, second pipeline, solvent pipeline, stirring pipeline, or raw material pipeline. Of course, it can also be connected to both ends of the fluid pipe of a heat exchanger to clean the fluid pipe. In short, if it is necessary to clean pipelines or equipment, the pipeline cleaning equipment can be used for cleaning. The pipeline cleaning equipment can even be applied to heat exchangers, connected to the inlet and outlet of the heat exchange tank respectively, to clean the heat exchange tank.

[0217] When there is no liquid pump installed on the pipeline to be cleaned, the pipeline cleaning equipment can also be connected to an external liquid pump, so that the detergent can circulate in each pipeline.

[0218] Specifically, the following example illustrates an application scenario for a pipeline cleaning device. The eleventh embodiment of this application provides an ink or adhesive mixing system, which includes the pipeline cleaning device described in the above embodiment.

[0219] The inkjet or adhesive spraying system in this embodiment includes all the components of the inkjet and adhesive spraying system in the first embodiment described above. Specifically, a pipeline cleaning device is installed on the raw material pipeline for cleaning the raw material pipeline. The two ends of the raw material pipeline are connected to an inlet pipeline and an outlet pipeline, specifically, to the first outlet of the inlet pipeline and the second inlet of the outlet pipeline, respectively. When the raw material pump is turned on, the liquid in the entire system circulates, and the detergent flows into the raw material pipeline through the inlet pipeline and then flows back into the washing tank from the outlet pipeline.

[0220] Similarly, the same principle applies when the pipeline cleaning equipment is installed on the solvent pipeline 432 or the stirring pipeline 442, so it will not be repeated here.

[0221] In addition, embodiments of this application can also integrate a heat exchanger, which can preheat the detergent to the required temperature (e.g., 40°C) to reduce the viscosity of the detergent. Since bubbles are more likely to diffuse in low-viscosity liquids, they work together with the solvent to form an efficient dynamic cleaning system, which can improve the cleaning effect.

[0222] The heat exchanger can be the heat exchanger described in the eighth and ninth embodiments above, for example, one end of the fluid pipe of the heat exchanger is connected to the first outlet of the inlet pipe, or the fluid pipe is connected to the second inlet of the outlet pipe.

[0223] Through this heat exchange structure, the detergent is heated before entering the washing tub, and together with the bubble disturbance, it forms a triple cleaning mechanism of "high temperature + dynamic + chemical", which greatly improves the cleaning efficiency and is especially suitable for stubborn ink layers or pipes that have not been cleaned for a long time.

[0224] Therefore, the system in this embodiment integrates multiple functions and has the advantages of thorough cleaning, precise control, energy saving and environmental protection, and flexible operation, making it suitable for various industrial liquid preparation and cleaning needs.

[0225] Those skilled in the art will understand that the above embodiments are specific examples of implementing this utility model, and some technical details in each embodiment can be applied interchangeably. To avoid repetition, some technical solutions and effects have not been described in detail in each embodiment. In practical applications, various changes can be made in form and detail without departing from the spirit and scope of this utility model.
