Description

Technical Field

[0001] This patent relates to the field of mixing equipment technology, specifically to a multifunctional ink cylinder. Background Technology

[0002] Ink is a homogeneous mixture composed of colored substances such as pigments and dyes, binders, fillers, and additives. It is a colored, fluid, paste-like adhesive that can be printed and dries on the printed surface. Therefore, color, consistency (including fluidity), and drying properties are the three most important properties of ink.

[0003] There are many types of printing inks, mainly used in various industries such as books, packaging, architectural decoration, and electronic circuit boards. Their physical properties also differ; some are very thick and viscous, while others are quite thin, especially the inks used in the tobacco industry, which have unique characteristics. Some use vegetable oil as a binder, while others use resin and solvents or water. These factors depend on the printing object (substrate), printing method, type of printing plate, and drying method. Existing printing ink preparation equipment mostly uses conventional vertically positioned agitators to mix the ink in a fixed direction. This cannot effectively solve the problem of uneven mixing when the ink is viscous, and subsequent cleaning of the ink tank is also difficult.

[0004] Currently, the method of transporting ink in the tobacco industry's tipping paper workshop involves operators manually pushing carts to deliver ink and manually lifting them to pour it in. This is time-consuming, labor-intensive, and prone to ink splattering, polluting the environment and making it difficult for tipping paper products to meet tobacco industry standards. Multi-color printing presses require frequent ink tank changes, and this repetitive work exacerbates physical exhaustion and reduces production efficiency. Ink properties are temperature-sensitive; ink viscosity in cold weather affects print quality, increasing the difficulty for operators to control quality. Therefore, a multi-functional ink tank that is easy to move, easy to clean, and capable of powerful agitation is needed. Utility Model Content

[0005] To address the problem of uneven ink mixing, reduce the difficulty of cleaning ink tanks, and improve the ease of use and versatility of ink tanks, this patent provides the following technical solutions:

[0006] Firstly, a multifunctional ink cylinder is provided, comprising a cylinder body liquid path mechanism, an ink tank liquid path mechanism, a cleaning mechanism, and a stirring mechanism. The cylinder body liquid path mechanism and the ink tank liquid path mechanism deliver and / or discharge liquid from the interior of the ink cylinder. Under the action of the cylinder body liquid path mechanism and / or the ink tank liquid path mechanism, the ink cylinder has a cleaning mode and a stirring mode.

[0007] Furthermore, the stirring mechanism is arranged along the axial direction inside the ink cylinder. The stirring mechanism includes a motor, a stirring shaft, and a stirring impeller. The motor is a pneumatic motor.

[0008] Furthermore, the cleaning mechanism is located on top of the ink cylinder. The cleaning mechanism includes multiple automatic rotating nozzles, with the number of automatic rotating nozzles being 2 to 4, 4 to 6, or 6 to 8. The rotation angle of the automatic rotating nozzles is 360°. The automatic rotating nozzles are equipped with printheads, with the number of printheads being 2 to 4, 4 to 6, or 6 to 8.

[0009] Furthermore, when the ink cylinder is in cleaning mode, the cleaning mechanism cleans the inside of the ink cylinder under the action of the cylinder liquid circuit mechanism.

[0010] Furthermore, when the ink cylinder is in stirring mode, the stirring mechanism mixes the materials inside the ink cylinder under the combined action of the cylinder liquid path mechanism and the ink tank liquid path mechanism; or when the ink cylinder is in stirring mode, the stirring mechanism mixes the materials inside the ink cylinder under the action of the cylinder liquid path mechanism.

[0011] Furthermore, the cylinder liquid circuit mechanism includes an inlet, an outlet, and a return outlet. The inlet and outlet, located at the bottom of the ink cylinder, deliver liquid into or out of the ink cylinder through pipes.

[0012] Furthermore, the ink tank liquid circuit mechanism includes an ink tank inlet connector, a first filter, and a first diaphragm pump. The first diaphragm pump connects the ink cylinder and the first filter and transports the liquid pneumatically. The first filter connects the ink tank inlet connector and the first diaphragm pump and filters the liquid entering the ink cylinder. The ink tank inlet connector connects the ink tank and the first filter.

[0013] Furthermore, the liquid enters the first filter from the ink tank inlet connector, removes impurities, and is then sent into the ink cylinder by the pneumatic action of the first diaphragm pump.

[0014] Furthermore, the ink tank liquid circuit mechanism also includes an ink tank return connector, a second filter, and a second diaphragm pump. The second diaphragm pump is connected to the ink cylinder and the second filter and transports liquid pneumatically. The second filter is connected to the ink tank inlet connector and the second diaphragm pump and filters the liquid entering the ink cylinder. The ink tank return connector is connected to the ink tank and the second filter.

[0015] Furthermore, the liquid is discharged from the ink cylinder through the pneumatic action of the second diaphragm pump to the second filter, and after impurities are removed, it enters the ink tank through the ink tank return connector; the liquid enters the second filter from the ink tank return connector, and after impurities are removed, it is sent into the ink cylinder under the pneumatic action of the second diaphragm pump.

The content is sufficient to enable any person skilled in the art to understand the technical content of this patent and implement it accordingly. Based on the specification, claims and drawings disclosed in this specification, a person skilled in the art can easily understand the related objectives and advantages of this patent.

[0056] To make the objectives, technical solutions, and advantages of this patent clearer, the embodiments of this patent will be described in further detail below with reference to the accompanying drawings.

[0057] A multi-functional ink cylinder, please refer to... Figures 1-3 It includes a cylinder body 100, a cylinder body liquid circuit mechanism 200, a stirring mechanism 300, a cleaning mechanism 400, an ink tank liquid circuit mechanism 500, and feet 600. The cylinder body 100 is a single-sided cylindrical structure with a concave bottom. The cylinder body 100 is a hollow cylindrical structure with an internal cavity that can accommodate the cleaning mechanism 400, the stirring mechanism 300, and the pipes connecting the various mechanisms. The feet 600 are arranged around the cylinder body 100 to support the normal operation of the cylinder body 100.

[0058] Specifically, the cylinder body 100 is a cylindrical shape with a convex bottom, forming a large cavity in the middle to hold liquid and house various mechanisms. The cylinder body 100 has a thick wall, and the wall material is chemically stable and not easily deformed. The wall material of the cylinder body 100 can be martensitic steel, ferritic steel, austenitic steel, austenitic-ferritic (duplex) stainless steel, precipitation hardening stainless steel, chromium stainless steel, chromium-nickel stainless steel, chromium-manganese-nitrogen stainless steel, and this patent is not limited to these.

[0059] Specifically, in this embodiment, the foot 600 has four support feet, which are equidistantly arranged on the outer wall of the cylinder 100 along the circumference. A solid column perpendicular to the bottom surface along the longitudinal direction of the outer wall is used to support and ensure that the cylinder 100 is not easily displaced in the working mode. The bottom of the column is equipped with casters to enhance the convenience of transporting the ink cylinder.

[0060] The cylinder body hydraulic system 200 includes a drain port 210, an inlet port 220, and a return port 230. The return port 230 is located at the top of the cylinder body 100 and next to the stirring mechanism 300. The return port 230 is connected to the return pipe 231. One end of the return port 230 extends into the cylinder body 100, and the other end is connected to the cleaning mechanism 400. The inlet port 220 and the drain port 210 are located at the bottom of the cylinder body 100. The inlet port 220 is connected to the inlet pipe 221, and the drain port 210 is connected to the drain pipe 211. One end of the inlet pipe 221 is connected to the inlet port 220, and the other end is connected to the first diaphragm pump 530. The inlet port 220 and the drain pipe 211 are connected by a T-junction. Notably, valves for controlling the flow rate are provided next to the inlet port 220, the return port 230, and the drain port 210.

[0061] The stirring mechanism 300 includes a motor 310, a speed regulating valve 320, a coupling 330, a stirring shaft 340, and a stirring impeller 350. The stirring mechanism 300 has an overall elongated structure. Specifically, the upper part is the cylindrical motor 310, and the side wall is connected to the motor air inlet pipe 311. The motor air inlet pipe 311 and the motor 310 are connected through the speed regulating valve 320. When the speed regulating valve 320 is open, air flows into the motor 310 from the motor air inlet pipe 311.

[0062] The motor 310 in this patent is a pneumatic motor, which can be a vane pneumatic motor, a piston pneumatic motor, a compact vane pneumatic motor, or a compact piston pneumatic motor; this patent is not limited to these. A pneumatic motor is a device that converts the energy of compressed air into mechanical energy. It drives an internal mechanical structure, such as vanes, pistons, or gears, to rotate or reciprocate through the expansion of gas. Its core characteristic is that it uses compressed air as a power source, rather than electricity or hydraulic oil.

[0063] Specifically, the advantages of pneumatic motors compared to other hydraulic motors are: pneumatic motors are small in size but can generate greater power; they can start and stop quickly and have stepless speed regulation. By controlling the opening of the intake or exhaust valve, i.e., controlling the flow of compressed air, the output power and speed of the motor can be adjusted; they can rotate in both directions. Most pneumatic motors can achieve forward and reverse rotation of the output shaft simply by using a control valve to change the direction of the motor's intake and exhaust, and can be reversed instantaneously with minimal impact during forward and reverse switching. A major advantage of pneumatic motors in reversing operation is their ability to reach full speed almost instantaneously. Vane-type pneumatic motors can reach full speed in one and a half seconds, while piston-type pneumatic motors can reach full speed in less than one second. By changing the air intake direction using a control valve, forward and reverse rotation can be achieved. This process is quick, fast, and has minimal impact, without requiring unloading. It also boasts a high safety factor. Because the internal pressure of a pneumatic motor is always higher than the external pressure during operation, it is unaffected by vibration, high temperature, electromagnetic fields, or radiation. It is suitable for harsh working environments, operating normally even in flammable, explosive, high-temperature, vibrating, humid, and dusty conditions, and even in underwater, dusty, humid, and dirty environments. Safe and explosion-proof, pneumatic motors do not generate sparks, overheating, explosions, short circuits, or other dangerous factors. They are particularly suitable for environments containing flammable and explosive substances or high temperatures, such as for stirring solvents, paints, and chemicals.

[0064] A coupling 330 is connected below the motor 310. The coupling 330 has a cylindrical structure with continuous holes on its side wall. Specifically, the coupling 330 is a safety device used to connect the motor 310 and the stirring shaft 340, providing overload protection.

[0065] The stirring shaft 340 is a long, thin cylindrical rod, usually made of a chemically stable material, used to stir the liquid in the ink tank without being easily corroded or contaminated. Specifically, it can be made of martensitic steel, ferritic steel, austenitic steel, austenitic-ferritic (duplex) stainless steel, precipitation hardening stainless steel, chromium stainless steel, chromium-nickel stainless steel, or chromium-manganese-nitrogen stainless steel. This patent is not limited to these.

[0066] The other end of the stirring shaft 340 is connected to the stirring impeller 350, which has an accordion pleated structure. This structure design allows for rapid stirring at the center of the liquid surface, causing the stirring impeller 350 and the liquid around the stirring shaft 340 to generate vortices under negative pressure, thereby accelerating the mixing of the liquid.

[0067] Specifically, the structure of the stirring impeller 350 can be selected from paddle type, curved blade turbine type, folded blade turbine type, disc turbine type, propeller type, Brumakin type, toothed blade type, anchor type, ribbon type and screw type, but this patent is not limited to these.

[0068] The motor 310 has a display panel at the top center. This display panel is a visualization module for the air control system of the stirring mechanism 300, and the user can use the display panel to precisely control the stirring mechanism 300.

[0069] The ink tank liquid circuit mechanism 500 includes an ink tank inlet connector 510, a first filter 520, a first diaphragm pump 530, an ink tank return connector 540, a second filter 550, and a second diaphragm pump 560.

[0070] The ink tank inlet connector 510, the first filter 520, and the first diaphragm pump 530 are interconnected. One end of the ink tank inlet connector 510 is connected to the ink tank, and the other end is connected to the first filter 520. It is mainly used to introduce new liquid from the ink tank in stirring mode. A valve is provided between the ink tank inlet connector 510 and the first filter 520 to regulate the flow rate of liquid introduced into the ink tank. The first filter 520 is mainly used to filter the liquid introduced from the ink tank, primarily removing impurities or particles to ensure the purity of the liquid entering the cylinder 100. One end of the first filter 520 is connected to the ink tank inlet connector 510, and the other end is connected to the first diaphragm pump 530. One end of the first diaphragm pump 530 is connected to the first filter 520, and the other end is connected to the inlet port 220. Liquid from the ink tank passes through the first diaphragm pump 530 and then flows through the inlet port 220 and into the cavity of the cylinder 100 from the bottom of the ink tank via the inlet pipe 221. The first diaphragm pump 530 is mainly used to transport or pressurize liquids, that is, to pump liquids from target containers such as ink tanks into the cavity of cylinder 100.

[0071] The ink tank return connector 540, the second filter 550, and the second diaphragm pump 560 are interconnected. One end of the ink tank return connector 540 is connected to the ink tank, and the other end is connected to the second filter 550. It is mainly used for the return of the mixed liquid in the cylinder 100 into the ink tank during stirring mode. A valve is provided between the ink tank return connector 540 and the second filter 550 to regulate the flow rate of the liquid introduced into the ink tank. The second filter 550 is mainly used to filter the mixed liquid in the cylinder before it returns to the ink tank, primarily filtering out impurities or particles to ensure the purity of the liquid entering the cylinder 100. One end of the second filter 550 is connected to the ink tank return connector 540, and the other end is connected to the second diaphragm pump 560. One end of the second diaphragm pump 560 is connected to the second filter 550, and the other end is connected to the internal cavity of the cylinder 100, allowing the mixed liquid in the cylinder to be transported and pressurized by the second diaphragm pump 560 into the second filter 550.

[0072] Specifically, the first diaphragm pump 530 and the second diaphragm pump 560 are pneumatic diaphragm pumps. Pneumatic diaphragm pumps use compressed gas as a power source and achieve liquid intake and discharge through the reciprocating deformation of the diaphragm, thereby achieving the purpose of fluid transportation. Its core component is the diaphragm, which is responsible for separating the pump's inlet and outlet and is connected to the gas source. When the gas source is sent into the diaphragm pump through the drive device, the diaphragm contracts and relaxes, causing periodic changes in the pump's inlet and outlet.

[0073] Pneumatic diaphragm pumps can completely pump out various corrosive liquids, liquids containing particles, and liquids that are highly viscous, volatile, flammable, or highly toxic.

[0074] Specifically, the pneumatic diaphragm pump in this embodiment can be made of engineering plastics, aluminum alloys, stainless steel, or cast iron. Depending on the different liquid media, it can be made of nitrile rubber, neoprene rubber, fluororubber, polytetrafluoroethylene, or polytetrafluoroethylene. This patent is not limited to these materials.

[0075] Compared with other pumps, the pneumatic diaphragm pump used in this embodiment has the following advantages: it is powered by compressed air, and the exhaust process is an expansion and heat absorption process, so the temperature decreases when the pneumatic pump is working and no harmful gases are emitted; because it is a positive displacement pump and the inlet is a ball valve, it is not easy to get clogged even when transporting liquids containing particles; it is not powered by electricity, and grounding can prevent electric sparks.

[0076] The first filter 520 and the second filter 550 used in this embodiment can be Y-type filter, basket filter, T-type filter, degassing filter, hand-cranked brush filter, dual-switching filter, backwash filter, fully automatic flushing filter, magnetic filter, pull rod telescopic filter, oxygen filter, high-pressure pipeline filter, terminal filter, etc. This patent is not limited to these.

[0077] The cleaning mechanism 400 includes two automatic rotating nozzles 410, each equipped with four nozzles. These nozzles are capable of 360° rotation and are primarily made of stainless steel, effectively resisting the strong impact generated by the nozzle rotation. The mechanism consists of a pair of bevel gears, a rotating seal assembly, and a hydraulic speed control device. During cleaning, the two nozzles are eccentric along their axial direction. The recoil force of the high-pressure water jet causes the small gear to rotate around the horizontal axis. Through the meshing action of the large gear, the rotating seal assembly rotates along the vertical axis, thus achieving 360° rotational cleaning without blind spots.

[0078] The pipe materials used in this patent can be rigid polyvinyl chloride (PVC-U) water supply pipes, random copolymer polypropylene (PP-R) water supply pipes, aluminum-plastic composite water supply pipes, cross-linked polyethylene (PE-X) water supply pipes, chlorinated polyvinyl chloride (PVC-C) water supply pipes, polyethylene (PE) water supply pipes, heat-resistant polyethylene (PE-RT) water supply pipes, acrylonitrile-butadiene-styrene (ABS) engineering plastic water supply pipes, copper pipes, thin-walled stainless steel pipes, hot-dip galvanized steel pipes, steel-lined (coated) plastic composite water supply pipes, stainless steel-lined composite steel pipes, and welded steel pipes. This patent is not limited to these.

[0079] The cylinder liquid passage mechanism 200 and the ink tank liquid passage mechanism 500 deliver liquid into and / or discharge it from the inside of the ink cylinder. Under the action of the cylinder liquid passage mechanism 200 and / or the ink tank liquid passage mechanism 500, the ink cylinder has a cleaning mode and a stirring mode.

[0080] In cleaning mode, liquid enters the cylinder 100 from the inlet 220 along the inlet pipe 221. The stirring mechanism 300 is activated to agitate the liquid in the cylinder 100 at high speed. The liquid along the wall washes the inner wall of the cylinder 100 under the action of circumferential rotational force, thus performing an initial rinse of the dirt on the inner wall. The return port 230 introduces some liquid from the cylinder 100 into the cleaning mechanism 400 through the return pipe 231. The cleaning mechanism 400 includes multiple automatic rotating nozzles 410. The liquid is liquefied into powerful small water jets and sprayed out from the nozzles of the automatic rotating nozzles 410. Under the rotation of the automatic rotating nozzles, the liquid sprays and cleans the inner wall of the cylinder 100, thus achieving thorough cleaning. Finally, the liquid enters the drain pipe 211 at the bottom and is discharged from the drain port 210.

[0081] In the ink tank-free stirring mode, the liquid enters the cylinder 100 from the inlet 220 along the inlet pipe 221. The stirring mechanism 300 is activated to stir the liquid in the cylinder 100 at high speed to mix the liquid. The liquid can also enter the cylinder 100 multiple times from the return port 230 through the return pipe 231, thereby mixing the liquid in the cylinder 100 multiple times. After mixing, the liquid enters the drain pipe 211 at the bottom and is discharged from the drain port 210.

[0082] In the mixing mode with ink tank involvement, liquid can enter the cylinder 100 from the inlet 220 along the inlet pipe 221. In the mixing mode without ink tank involvement, when liquid in the cylinder 100 needs to be added to the ink tank, the introduced liquid enters the ink tank inlet pipe 511 from the ink tank inlet connector 510, and after being filtered by the first filter 520, it enters the cylinder 100 under the action of the first diaphragm pump 530 to mix with the original solution. At this time, the stirring mechanism 300 can be turned on to accelerate this mixing. Liquid can also enter the cylinder 100 multiple times from the return port 230 through the return pipe 231, thereby mixing the liquid in the cylinder 100 multiple times. After mixing, the liquid can be sent to the second filter 550 through the second diaphragm pump 560. After filtration, the liquid enters the ink tank from the second filter 550 through the ink tank return pipe 541 and the ink tank return connector 540.
