Description

Technical Field

[0001] This application belongs to the technical field of printing equipment, and particularly relates to an ink supply damper, an ink supply assembly, a printing device, and an inkjet printing production line. Background Art

[0002] A UV printing device is a printing device that achieves fast and high-quality printing through ultraviolet curing technology. The print head ejects tiny ink droplets according to image data. These ink droplets land on the surface of the printing medium, and a UV lamp installed near the print head emits ultraviolet light, causing the photosensitizer in the ink to undergo a chemical reaction and quickly solidify into a solid ink layer, achieving the effect of drying immediately after printing.

[0003] During the operation of the printing device, the print head moves relative to the printing medium for printing actions, and at the same time, the ink tube connected to the print head also moves, resulting in a change in the pressure inside the ink tube. Also, during the ink supply and ink return processes, due to factors such as the pumping device and the remaining ink volume in the ink cartridge, the pressure inside the ink tube will also change, which is likely to cause uneven inkjetting of the print head. Summary of the Utility Model

[0004] This application aims to at least solve the technical problem of uneven inkjetting of the print head to a certain extent. For this purpose, this application provides an ink supply damper, an ink supply assembly, a printing device, and an inkjet printing production line.

[0005] In a first aspect, this application provides an ink supply damper, including: a housing, an inlet liquid cavity is formed inside the housing, an ink inlet hole and an ink outlet hole communicating with the outside are formed on the side wall of the inlet liquid cavity, and the ink inlet hole and the ink outlet hole are respectively located at both ends of the housing; a damping cavity, the damping cavity is arranged on the top of the housing; a flow blocking plate assembly, the flow blocking plate assembly is arranged at the bottom of the inlet liquid cavity and is located between the ink inlet hole and the ink outlet hole.

[0006] Through the technical solution in this embodiment, the ink supply pipeline is connected to the ink inlet hole of the ink supply damper, and the ink using pipeline is connected to the next process. After the pumping assembly pumps the ink into the liquid inlet chamber of the ink supply damper through the ink inlet hole, when the ink flows towards the ink outlet hole, it first contacts the baffle plate assembly. Under the obstruction of the baffle plate assembly, it flows through the gap between the baffle plate and the side wall. Through the obstruction of the baffle plate assembly, the flow rate of the ink is effectively reduced, and the residence time of the ink in the liquid inlet chamber is increased. When the pressure inside the ink pipe changes, first, the baffle plate assembly obstructs and absorbs the fluctuation of the ink, and at the same time, the pressure in the liquid inlet chamber will change accordingly. The pressure fluctuation is transmitted to the damping chamber, and the volume of the gas in the damping chamber changes. The gas chamber in the damping chamber is used to absorb and compensate the pressure in the liquid inlet chamber, thereby further reducing the amplitude of the pressure fluctuation inside the ink pipe. By adjusting the ink flow rate and pressure fluctuation from two aspects, the situation of uneven inkjet of the print head is solved to a certain extent.

[0007] In some embodiments, the baffle plate assembly includes a plurality of baffle plates arranged at intervals, and the plurality of baffle plates are arranged staggeredly along the width direction of the housing. When the ink flows to the first baffle plate, it flows along the plate surface towards the gap on one side, and after passing through the gap, it reaches the next plate surface and flows towards the gap on the other side. By arranging a plurality of baffle plates, the flow path of the ink is further increased, and the obstruction effect on the ink is further improved.

[0008] In some embodiments, the height of the baffle plate is not less than the diameter of the ink inlet hole. After the ink enters, it is completely obstructed by the baffle plate, preventing the ink from flowing out directly over the baffle plate.

[0009] In some embodiments, the baffle plate is a bent structural member. Further extending the flow path of the ink improves the obstruction effect on the ink.

[0010] In some embodiments, a plurality of damping chambers are provided along the length direction of the housing. It enables effective adjustment of the pressure fluctuations at different internal positions, and further improves the adjustment effect on the pressure fluctuations.

[0011] In some embodiments, the ink supply damper further includes a heating assembly. The ink is heated by the heating assembly to prevent the viscosity and temperature of the ink from changing due to the long flow time during the flow process, making it more in line with the expected requirements and improving the use effect of the ink.

[0012] In some embodiments, the heating assembly is provided on the housing, and the baffle plate is connected to the heating assembly. The baffle plate is used as the heat transfer component of the heating assembly, so that the ink can be continuously heated by the heating assembly when flowing along the baffle plate, improving the heating effect on the ink.

[0025] The present application will be described below with reference to the accompanying drawings and specific embodiments:

[0026] In the field of battery production, a battery separator needs to be formed on the battery surface to protect the battery surface and prevent damage to the battery from the external environment. Generally, a battery blue film is used as the separator for coating in this field. This material has good insulation performance, waterproof, moisture-proof, voltage-resistant, puncture-resistant, weather-resistant, oxidation-resistant, chemical-resistant, and high mechanical strength and other characteristics.

[0027] In traditional processes, the finished PET blue film material is often coated on the battery surface by thermoplastic methods. However, the PET blue film material is prone to aging and has a poor fitting effect. Therefore, the present application adopts the battery inkjet UV printing technology to spray the liquid ink of the blue film material on the battery surface to form the battery blue film. Therefore, in order to form a uniformly distributed and smooth battery blue film surface, the requirements for the ink output stability of the print head of the UV printing equipment are very high. During the operation of the printing equipment, the print head moves relative to the printing medium for printing operations, and at the same time, the ink pipeline connected to the print head also moves, resulting in changes in the pressure inside the ink pipeline. And during the ink supply and ink return processes, due to factors such as the pumping equipment and the remaining ink volume in the ink cartridge, the pressure inside the ink pipeline will also change, which in turn causes uneven inkjet of the print head, resulting in a low flatness of the formed battery blue film, and even the occurrence of bubbles, voids, and other situations.

[0028] In the related art, a cavity is often provided in a component such as a flow divider, and the pressure fluctuation is absorbed and adjusted by the gas in the cavity. However, the absorption effect of only relying on air for pressure fluctuation cannot meet the requirements in some cases. Therefore, the present application provides an ink supply damper, an ink supply component, a printing device, and an inkjet printing production line, which can at least solve the technical problem of uneven inkjetting of the print head to a certain extent.

[0029] Embodiment 1: The embodiment of the present application provides an ink supply damper, including:

[0030] A housing 100, a damping cavity 120 provided in the housing 100, and a flow blocking plate assembly. An ink inlet cavity 110 is provided in the housing 100. An ink inlet hole 111 and an ink outlet hole 112 communicating with the outside are provided on the side wall of the ink inlet cavity 110. The ink inlet hole 111 and the ink outlet hole 112 are respectively located at both ends of the housing 100. The damping cavity 120 is provided on the top of the housing 100 and above the ink inlet cavity 110. In this embodiment, the housing 100 is a rectangular housing 140, and a rectangular hollow cavity is provided inside the housing 100. The cavity located below is used as the ink inlet cavity 110 for accommodating ink, and the cavity located above is used as the damping cavity 120 for absorbing pressure fluctuations. When the ink enters the ink inlet cavity 110 and submerges the ink inlet hole 111 and the ink outlet hole 112, the damping cavity 120 located at the top becomes a closed chamber. When there is a pressure fluctuation during ink inlet, the pressure fluctuation is transmitted to the gas chamber in the damping cavity 120, and the volume of the gas in the damping cavity 120 changes, so as to realize the absorption and compensation of the pressure fluctuation in the ink inlet cavity 110.

[0031] Specifically, the housing 100 includes a top cover 130 and a housing 140. An opening is provided above the housing 140, and the top cover 130 is detachably provided on the housing 140 to close the opening. A plurality of mounting holes are provided on the edge of the housing 100, and a plurality of threaded holes adapted to them are provided on the edge of the housing 140, so as to fix the top cover 130 on the housing 140 to form a closed chamber, or directly insert them by an interference fit method. In this embodiment, the ink inlet cavity 110 is provided in the housing 140, and the ink inlet cavity 110 is provided on the inner side wall of the top cover 130 facing the inside. After the top cover 130 and the housing 140 are buckled, a complete closed chamber is formed.

[0032] In other embodiments, the housing 100 can also be manufactured by an integrally formed method, or the entire cavity is completely provided in the housing 140 to make the whole structure simpler.

[0033] The ink inlet hole 111 and the ink outlet hole 112 are respectively opened on the side walls of the shell 100 along the length direction of the shell 140, and are located at the bottom of the liquid inlet cavity 110. After the ink enters from the ink inlet hole 111, it flows through the entire liquid inlet cavity 110 and then flows out from the ink outlet hole 112. In some preferred embodiments, the lowest points of the ink inlet hole 111 and the ink outlet hole 112 are located below the bottom wall of the liquid inlet cavity 110, and sinking grooves 113 are opened at the corresponding positions of the ink inlet hole 111 and the ink outlet hole 112 on both sides of the bottom wall of the liquid inlet cavity 110, so that the ink can completely flow out through the sinking grooves 113 after the work is completed, thereby reducing the ink residue in the liquid inlet cavity 110.

[0034] In some embodiments, an ink inlet tube connected to the ink inlet hole 111 and an ink outlet tube connected to the ink outlet hole 112 are provided on the side wall of the shell 100. The ink inlet tube and the ink outlet tube are standard parts for pipeline connection, which are used to connect with the ink supply pipeline and the ink use pipeline of the external ink supply. In this embodiment, the ink inlet tube and the ink outlet tube are both detachable, which is convenient for replacing different models according to actual conditions. In other embodiments, they can also be integrally formed with the shell 140.

[0035] The baffle assembly is staggered at the bottom of the liquid inlet chamber 110 and located between the ink inlet hole 111 and the ink outlet hole 112. In this embodiment, the baffle assembly includes a plurality of spaced baffles 300, which are fixed at the bottom of the housing 100 in a direction perpendicular to the bottom wall of the liquid inlet chamber 110. A gap is left between the baffle 300 and the side wall of the liquid inlet chamber 110. The ink inlet hole 111 and the ink outlet hole 112 are both located at the center of their side walls. The ink inlet hole 111 can also be opened at a position corresponding to the gap of the baffle 300 on one side, and the ink outlet hole 112 can be opened at a position staggered from the gap of the baffle 300 on one side, so as to further extend the flow path of the ink.

[0036] Through the technical solution in this embodiment, when applying the ink supply damper to a UV printing device for blue film printing on the surface of a battery, connect the ink supply pipeline to the ink inlet hole 111 of the ink supply damper and the ink using pipeline to the next process. When the pumping assembly pumps ink into the liquid inlet chamber 110 of the ink supply damper through the ink inlet hole 111, the ink first contacts the baffle plate 300 during the process of flowing towards the ink outlet hole 112, and flows through the gap between the baffle plate 300 and the side wall under the obstruction of the baffle plate 300. Through the obstruction of the baffle plate 300, the flow rate of the ink is effectively reduced, and the residence time of the ink in the liquid inlet chamber 110 is increased. When the pressure inside the ink pipe changes, first, the baffle plate 300 obstructs and absorbs the fluctuations of the ink, and at the same time, the pressure in the liquid inlet chamber 110 changes accordingly. The pressure fluctuation is transmitted to the gas chamber in the damping chamber 120, and the volume of the gas in the damping chamber 120 changes. The gas chamber in the damping chamber 120 is used to absorb and compensate the pressure in the liquid inlet chamber 110, thereby further reducing the amplitude of the pressure fluctuation inside the ink pipe. By adjusting the ink flow rate and pressure fluctuation from two aspects, the situation of uneven inkjet of the print head is solved to a certain extent.

[0037] In some preferred embodiments, the ink supply damper further includes a damping diaphragm 200. The damping diaphragm 200 is hermetically arranged in the chamber of the housing 100 in the horizontal direction, thereby dividing the entire chamber into a liquid inlet chamber 110 and a damping chamber 120. The ink inlet hole 111 and the ink outlet hole 112 are both located below the damping diaphragm 200. When the ink enters the liquid inlet chamber 110, a gas chamber is formed between the hermetically arranged damping diaphragm 200 and the liquid level of the ink. When the ink submerges the ink inlet hole 111 and the ink outlet hole 112, a sealed gas chamber is formed. When the pressure changes, the air chamber can first absorb the pressure fluctuation preliminarily, and then transmit the pressure fluctuation to the damping diaphragm 200, causing the damping diaphragm 200 to undergo elastic deformation to achieve the absorption of the pressure fluctuation, thereby reducing the amplitude of the pressure fluctuation inside the ink pipe.

[0038] A pressure relief hole 131 is provided on the top cover 130. The pressure relief hole 131 is arranged at the center of the top cover 130. When the pressure in the liquid inlet chamber 110 changes and the damping diaphragm 200 deforms, the gas in the damping chamber 120 can enter or exit through the pressure relief hole 131, so that the force generated by the pressure fluctuation acts more on the damping diaphragm 200, improving the pressure absorption effect of the damping diaphragm 200. In this embodiment, one pressure relief hole 131 is provided. In other embodiments, according to actual needs, multiple pressure relief holes 131 can be provided to improve the pressure relief effect. Or when it is necessary to make an avoidance according to actual conditions, the pressure relief hole 131 can be provided on the side wall of the top cover 130 or the housing 140.

[0039] Specifically, the top of the shell 140 is located in the installation opening and is sunken to form an installation groove 150. The damping diaphragm 200 is detachably arranged in the installation groove 150, wherein the liquid inlet chamber 110 is located in the shell 140, and the damping chamber 120 is opened at the bottom of the top cover 130. When the damping diaphragm 200 is located in the installation groove 150, the bottom of the top cover 130 is in sealed contact with the damping diaphragm 200 to form the damping chamber 120. The damping diaphragm 200 is in sealed contact with the shell 140, thereby forming a liquid inlet chamber 110 between the top wall of the shell 140. When disassembling, the top cover 130 can be removed to achieve the installation or replacement of the damping diaphragm 200, which is more convenient to operate. In some other embodiments, the damping diaphragm 200 can also be fixedly installed in the installation groove 150 by other methods such as threaded connection or bonding to improve the sealing and stability of the damping diaphragm 200.

[0040] In this embodiment, the damping diaphragm 200 is made of an elastic material, for example, a rubber material, so that the damping diaphragm 200 is easier to deform and more sensitive to pressure fluctuations. The thickness of the damping diaphragm 200 can be set according to actual application conditions. The smaller the thickness, the higher the sensitivity to pressure changes, but the lower the pressure bearing limit. In other embodiments, the material of the damping diaphragm 200 can be selected according to actual conditions. For example, when the flow rate of the ink supply pipeline is large but the size of the ink supply damper is limited, a material with greater elasticity can be used to provide a larger pressure bearing limit.

[0041] In some embodiments, multiple baffles 300 in the baffle assembly are spaced apart on the bottom wall of the liquid inlet chamber 110 along the length direction of the housing 100, one side of the baffle 300 is fixedly connected to the side wall of the liquid inlet chamber 110, and a gap is left between the other side and the other side wall of the liquid inlet chamber 110. The multiple baffles 300 are staggered along the width direction of the housing 100. In this embodiment, the staggered arrangement means that, viewed along the length direction of the housing, the gap between each baffle and the side wall is blocked by other baffles, so that the ink does not pass directly in a straight line when passing through the baffle assembly.

[0042] Among them, there can be various specific forms of the staggered arrangement. For example, the first baffle plate 300 is fixedly connected to the left side wall and has a gap with the right side wall, and the second baffle plate 300 is fixedly connected to the right side wall and has a gap with the left side wall. The gaps between the two baffle plates 300 are completely staggered along the length direction of the shell 100, so that the ink can be completely blocked by the other baffle plate 300 after passing through the gap, thereby forming a tortuous ink flow path, thereby improving the flow path of the ink and reducing the flow rate of the ink.

[0043] In other embodiments, the baffle 300 can also be arranged in other ways. For example, the first baffle 300 is fixedly arranged in the middle position with gaps left on both sides, the two sides of the second baffle 300 are fixedly connected to the side walls on both sides of the liquid inlet chamber 110, and the gaps are opened in the middle position. The gaps between the two baffles 300 are completely staggered when viewed along the length direction of the housing 100, and the ink blocking effect can also be achieved. Or multiple gaps can be opened in each baffle 300, as long as it is ensured that the gaps between adjacent baffles 300 are completely staggered when viewed along the length direction of the housing 100.

[0044] In some embodiments, at least three baffles 300 are provided, and the multiple baffles 300 are evenly spaced to make the flow velocity change of the ink between the respective baffles 300 the same, so that the regulation effect of the multiple baffles 300 on the flow velocity and pressure fluctuation of the ink is more uniform. According to the actual situation and the size of the housing 100, the number of the baffles 300 can be adjusted to maximize the ink blocking effect.

[0045] In some embodiments, the height of the baffle 300 is not less than the diameter of the ink inlet hole 111. The ink inlet hole 111 is arranged close to the bottom wall of the liquid inlet chamber 110, and the height of the baffle 300 is greater than the height of the highest position of the ink inlet hole 111. After the ink enters, it is completely blocked by the baffle 300, preventing the ink from flowing directly to the ink outlet hole 112 across the baffle 300.

[0046] In other embodiments, the baffle 300 can also be inclined towards the side close to the ink inlet hole 111. When the ink liquid level exceeds the baffle 300, it will flow along the plate surface of the baffle 300 towards the side close to the ink inlet hole 111, further preventing the ink from flowing over the baffle 300, and maximizing the ink blocking effect of the baffle 300.

[0047] In some embodiments, the baffle 300 is a plate-like structural member with a cross-section in a bent shape. The baffle 300 is bent along the width direction, thereby increasing the plate surface length of the baffle 300 in the width direction, and further increasing the flow path of the ink. In this embodiment, the cross-section of the baffle 300 can be V-shaped, and the concave surface of the baffle 300 faces the side of the ink inlet hole 111. When the ink flows along the concave surface after encountering the baffle 300, a turbulent flow towards the side close to the ink inlet hole 111 is formed, further improving the ink blocking effect. In other embodiments, the baffle 300 can also be arranged in other shapes such as a wavy shape or an arc shape.

[0048] In some embodiments, a plurality of damping chambers 120 are provided along the length direction of the housing 100. In this embodiment, two damping chambers 120 are provided, and the two damping chambers 120 are arranged side by side along the length direction of the housing 100, so that the pressure fluctuations at different internal positions can be effectively adjusted, further improving the adjustment effect on the pressure fluctuations. In other embodiments, the number of the damping chambers 120 can be set to other numbers according to the actual situation and size to further improve the adjustment effect on the pressure fluctuations.

[0049] In some embodiments, the ink supply damper further includes a heating component 400. The ink is heated by the heating component 400 to prevent the viscosity and temperature of the ink from changing due to a long flow time during the flow process, making it more in line with the expected requirements and improving the use effect of the ink. Specifically, the heating component 400 is arranged inside the housing 100. In this embodiment, the heating component 400 includes a heating element, and the heating element is connected to an external heat supply device. For example, an electric heating method can be adopted, or the heating element is a hollow pipe fitting, and the heating element is heated by an external heat-conducting fluid.

[0050] In some embodiments, the heating element is arranged at the bottom of the housing 100 and below the baffle 300. The baffle 300 is connected to the heating component 400, and the heating component 400 can transfer heat to the baffle 300, using the baffle 300 as a heat transfer component of the heating component 400, so that the ink can be continuously heated by the heating component 400 when flowing along the baffle 300, thereby improving the heating effect on the ink; in other embodiments, the heating component 400 can further include a conduction member, one end of the conduction member is thermally connected to the heating element, and the other end extends into the liquid inlet chamber 110 and directly contacts the ink, so as to directly heat the ink.

[0051] In some preferred embodiments, the heating component 400 can be arranged inside the baffle 300, so as to directly use the baffle 300 as a part of the heating component 400 to directly heat the ink, thereby further improving the heating effect on the ink.

[0052] In some preferred embodiments, the heating component 400 further includes a temperature sensor. The ink in the ink supply damper is monitored by the temperature sensor, and the heating temperature of the heating component 400 is adjusted in real time according to the temperature, so that the ink is maintained at a preset temperature, thereby further improving the heating effect on the ink and making it more in line with the viscosity and temperature required for printing.

In this embodiment, the printing device can be a UV printing device for battery blue film, including an external ink supply component and an external ink using component, and further including the above-mentioned ink supply damper.

When the external ink using component is a single print head, the adjustment effect of pressure fluctuation is directly achieved through the ink supply damper; or it includes the above-mentioned ink supply component, the ink inlet hole 111 is connected to the external ink supply component, and the ink outlet end of the flow splitting component is connected to the external ink using component. When the external ink using component is multiple print heads, the ink that has been adjusted by the ink supply damper is split by the ink supply splitter, so as to adapt to multiple print heads.
