Description

[0002] With the development of the lithium battery industry, the requirements for the structural strength of battery cell surfaces are becoming increasingly stringent. The traditional method of covering square battery cells with blue film and attaching insulating covers is increasingly unable to meet the industry's needs.

Therefore, the relevant specifications of the battery cells need to be printed on the insulating coating of the battery cells.

[0003] During inkjet printing, ink needs to be delivered, and this is usually done through pipelines to add ink to the printing equipment. However, when the printing equipment is not in operation, ink is prone to settling in the pipelines, causing ink blockage and resulting in low ink supply efficiency. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0035] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this utility model are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of the utility model described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0036] This utility model provides a printing ink supply device. The device extracts ink from the ink tank using an ink supply module and pressurizes the extracted ink using an output pressurization module. This enables long-distance ink transport and centralized ink supply. When the printing equipment is not in use, the ink supply module, output pressurization module, and reflux control module facilitate ink circulation, preventing ink blockage and improving ink supply efficiency. Figure 1 This is a schematic diagram of a printing ink supply device provided in an embodiment of this utility model. (Refer to...) Figure 1 The ink supply device for printing includes: at least one ink supply module 110, an output pressure module 130, a reflux control module 140, and a control module 150.

[0037] The ink supply module 110 is used to extract ink from the ink tank 10. The output end of the ink supply module 110 is connected to the input end of the output pressure module 130. The output end of the output pressure module 130 is connected to the printing equipment 20 and the reflux control module 140 respectively. The reflux control module 140 is also connected to the ink supply module 110. The ink supply module 110, the output pressure module 130, the reflux control module 140 and the printing equipment 20 are also connected to the control module 150. The control module 150 is used to control the start and stop of the ink supply module 110, the output flow rate of the output pressure module 130, and the on or off of the reflux control module 140.

[0038] Specifically, the ink supply module 110 includes an ink tank 10. The ink supply module 110 detects the ink level in the ink tank 10 and generates a low-level signal when the ink level in the ink tank 10 is lower than a preset level. The preset level is a pre-set minimum level to indicate that there is still ink in the ink tank 10. When the ink level in the ink tank 10 is lower than the preset level, it is considered that there is no ink in the ink tank 10. At this time, the control module 150 acquires the low-level signal and controls the ink supply module 110 to stop drawing ink.

[0039] The ink supply module 110 is connected to the output pressure module 130, the reflux control module 140 is connected to the output pressure module 130, the reflux control module 140 is connected to the ink supply module 110, and the output pressure module 130 is connected to the printing equipment 20 via the ink supply pipeline 120.

[0040] The ink supply module 110 delivers the ink from the ink tank 10 to the output pressurization module 130. The output pressurization module 130 agitates and pressurizes the ink to make it more uniform and increase its pressure, thereby increasing the ink's transmission distance. The control module 150 controls the reflux control module 140 to be turned on or off according to the working needs of the printing equipment 20. When the printing equipment 20 has working needs, the control module 150 controls the reflux control module 140 to be turned off, at which time all the ink output by the output pressurization module 130 is supplied to the printing equipment 20; when the printing equipment 20 has no working needs, the control module 150 controls the reflux control module 140 to be turned on. At this time, since the printing equipment 20 has no working needs, it is turned off, that is, the printing equipment 20 stops receiving ink, and all the ink output by the output pressurization module 130 is supplied to the reflux control module 140, and then sent back to the ink supply module 110 through the reflux control module 140, thus returning to the ink tank 10. In other words, when the printing equipment 20 is not in use, the ink circulates within the ink tank 10, the ink supply module 110, the output pressurization module 130, and the reflux control module 140 to ensure the fluidity of the ink and prevent ink settling and clogging.

[0041] This embodiment of the invention uses an ink supply module 110 to extract ink from the ink tank 10 and deliver it to an output pressurization module 130. The output pressurization module 130 agitates and pressurizes the ink to achieve long-distance ink delivery. When the printing equipment 20 is not in operation, the control module 150 controls the reflux control module 140 to circulate the ink within the ink tank 10, ink supply module 110, output pressurization module 130, and reflux control module 140, thus ensuring ink flowability. This embodiment of the invention uses an ink supply module 110 to extract ink from the ink tank 10 and an output pressurization module 130 to pressurize the extracted ink, achieving long-distance ink delivery and centralized ink supply. When the printing equipment 20 is not in operation, the ink supply module 110, output pressurization module 130, and reflux control module 140 facilitate ink circulation, which helps prevent ink blockage and improves ink supply efficiency.

[0042] Figure 2 This is a schematic diagram of another ink supply device for printing provided by an embodiment of this utility model. Optionally, based on the above embodiments, refer to... Figure 2The ink supply module 110 includes: a cover plate 111, an ink supply pump 112, a return port 113, and an ink level sensor 114.

[0043] The ink supply pump 112, the reflux interface 113, and the ink level sensor 114 are mounted on and pass through the cover plate 111. The ink supply pump 112, the reflux interface 113, and the ink level sensor 114 are fixedly connected to the cover plate 111. The ink supply pump 112 is connected to the output pressurization module 130, and the reflux interface 113 is connected to the reflux control module 140. The ink supply pump 112 and the ink level sensor 114 are also connected to the control module 150. The ink supply pump 112 is used to draw ink from the ink tank 10. The ink level sensor 114 is used to detect the ink level in the ink tank 10. The control module 150 is used to control the start and stop of the ink supply pump according to the ink level in the ink tank.

[0044] Specifically, the ink supply pump 112 and the ink level sensor 114 are inserted into the ink tank 10. The ink supply pump 112 draws ink from the ink tank 10. The ink level sensor 114 detects the ink level in the ink tank 10 and generates a low level signal when the ink level is lower than a preset level. The control module 150 acquires this low level signal and controls the ink supply module 110 to stop drawing ink. It should be noted that the cover plate 111 covers the opening of the ink tank 10 to seal the ink tank 10, thereby preventing ink evaporation. The return flow control module 140 is connected to the return flow interface 113. When the printing equipment 20 is not in operation, the ink output by the return flow control module 140 flows back into the ink tank 10 through the return flow interface 113.

[0045] Based on the above embodiments, optionally, refer to... Figure 2 The ink supply pump 112 includes a pump body 1121, a pump tube 1122, and an output tube 1123. The pump tube 1122 and the output tube 1123 pass through the cover plate 111. The pump body 1121 is connected to the pump tube 1122. The pump body 1121 is located on the side of the cover plate 111 away from the ink tank 10. The output tube 1123 is connected to the pump tube 1122 and is also connected to the output pressurization module 130.

[0046] Specifically, the pump tube 1122 is inserted into the ink tank 10. Driven by the pump body 1121, the ink in the ink tank 10 flows through the pump tube 1122 into the output tube 1123 and is output to the output pressurization module 130. Optionally, in actual use, the pump tube 1122 can also be integrated with a stirring mechanism. The stirring mechanism is coaxially mounted with the pump tube 1122 and is also driven by the pump body 1121, thereby stirring the ink while drawing it to further ensure the fluidity of the ink.

[0047] Based on the above embodiments, optionally, refer to... Figure 2 The ink supply module 110 also includes a lifting mechanism 115.

[0048] The ink supply pump 112 is fixed to the lifting mechanism 115; the lifting mechanism 115 is used to insert the ink supply pump 112 into the ink tank 10 or to pull the ink supply pump 112 out of the ink tank 10. Specifically, the lifting mechanism 115 can be connected to the control module 150, which controls the lifting of the lifting mechanism 115. Alternatively, a separate control mechanism can be set up for control. In practical applications, the configuration can be set according to actual needs, and this embodiment does not impose any restrictions on this.

[0049] Based on the above embodiments, optionally, refer to... Figure 2 The lifting mechanism 115 includes: a base 1151, a first lifting column 1152, a second lifting column 1153, a connecting plate 1154, and a bearing plate 1155.

[0050] A first lifting column 1152 and a second lifting column 1153 are fixed on the base 1151. The first lifting column 1152 and the second lifting column 1153 are perpendicular to the base 1151. A connecting plate 1154 and a bearing plate 1155 are connected between the first lifting column 1152 and the second lifting column 1153. An ink pump 112 is fixed on the bearing plate 1155.

[0051] Based on the above embodiments, optionally, refer to... Figure 2 The output pressurization module 130 includes: an output mixing tank 131, a first output pressurization flow meter 132, a second output pressurization flow meter 133, an output pump 134, an output valve 135, and an output liquid level sensor 136.

[0052] The output inlet of the output mixing tank 131 is connected to the first end of the first output pressure flow meter 132. The second end of the first output pressure flow meter 132 is connected to the ink supply module 110. The output end of the output mixing tank 131 is connected to the first end of the second output pressure flow meter 133. The second end of the second output pressure flow meter 133 is connected to the input end of the output pump 134. The output end of the output pump 134 is connected to the first end of the output valve 135. The second end of the output valve 135 is connected to the inkjet printing equipment 20 and the reflux control module 150, respectively. The liquid level detection end of the output mixing tank 131 is connected to the output liquid level sensor 136. The control end of the output valve 135 is connected to the control module 150. The signal ends of the first output pressure flow meter 132 and the second output pressure flow meter 133 are both connected to the control module 150.

[0053] Specifically, the ink supply module 110 delivers the ink from the ink tank 10 to the output mixing tank 131. The first output pressure flow meter 132 acquires the flow rate of the ink in the ink supply pipeline 120 between the ink supply module 110 and the output mixing tank 131. The output mixing tank 131 agitates the ink, and the ink in the output mixing tank 131, under the action of the output pump 134, is output to the printing equipment 20 through the second output pressure flow meter 133 and the output valve 135. The control module 150 acquires the ink flow rate detected by the first output pressure flow meter 132 and the second output pressure flow meter 133, and controls the flow rate of ink output to the printing equipment 20 based on the required flow rate for the printing equipment 20, the ink flow rate detected by the first output pressure flow meter 132 and the ink flow rate detected by the second output pressure flow meter 133, and the power of the output pump 134.

[0054] Based on the above embodiments, optionally, refer to... Figure 2 The reflux control module 140 includes: a reflux control valve 141.

[0055] The output pressurization module 130 is connected to the first end of the reflux control valve 141, the second end of the reflux control valve 141 is connected to the ink supply module 110, and the control end of the reflux control valve 141 is connected to the control module 150.

[0056] Specifically, when the printing equipment 20 has a working demand, the control module 150 controls the return control valve 141 to close, at which time all the ink output by the output pressurization module 130 is supplied to the printing equipment 20; when the printing equipment 20 has no working demand, the control module 150 controls the return control valve 141 to open, at which time, since the printing equipment 20 has no working demand, the printing equipment 20 is closed, that is, the printing equipment 20 stops receiving ink, and all the ink output by the output pressurization module 130 is supplied to the return control valve 141, and is sent back to the ink supply module 110 through the return control valve 141, thereby returning to the ink tank 10.

[0057] Figure 3 This is a schematic diagram of another ink supply device for printing provided by an embodiment of this utility model. Optionally, based on the above embodiments, refer to... Figure 3 The inkjet printing ink supply device also includes at least one intermediate pressurization module 160.

[0058] The input terminal of the transfer pressurization module 160 is connected to the ink supply module 110, the output terminal of the transfer pressurization module 160 is connected to the output pressurization module 130, and the control terminal of the transfer pressurization module 160 is connected to the control module 150.

[0059] Specifically, the ink supply module 110 delivers the ink from the ink tank 10 to the intermediate pressurization module 160. The intermediate pressurization module 160 agitates and pressurizes the ink to make it more uniform and increases its pressure, thereby increasing the ink's transmission distance. The pressurized ink from the intermediate pressurization module 160 is then delivered to the output pressurization module 130. The output pressurization module 130 agitates and pressurizes the ink again to further increase its transmission distance. The control module 150 controls the on / off state of the return flow control module 140 according to the operating requirements of the printing equipment 20. When the printing equipment 20 has a working demand, the control module 150 controls the return flow control module 140 to turn off. At this time, all the ink output by the output pressure module 130 is supplied to the printing equipment 20. When the printing equipment 20 has no working demand, the control module 150 controls the return flow control module 140 to turn on. At this time, since the printing equipment 20 has no working demand, it turns off, that is, the printing equipment 20 stops receiving ink. All the ink output by the output pressure module 130 is supplied to the return flow control module 140, and then sent back to the ink supply module 110 through the return flow control module 140, thus returning to the ink tank 10. In other words, when the printing equipment 20 has no working demand, the ink circulates within the ink tank 10, the ink supply module 110, the transfer pressure module 160, the output pressure module 130, and the return flow control module 140 to ensure ink flowability and prevent ink settling and clogging.

The second terminal of the first transfer pressurized flow meter 162 is connected to the ink supply module 110. The output terminal of the transfer mixing tank 161 is connected to the first terminal of the second transfer pressurized flow meter 163.

The output terminal of the transfer pump 164 is connected to the first terminal of the transfer valve 165. The second terminal of the transfer valve 165 is connected to the output pressurization module 130. The liquid level detection terminal of the transfer mixing tank 161 is connected to the transfer liquid level sensor 166. The control terminal of the transfer valve 165 is connected to the control module 150. The signal terminals of the first transfer pressurized flow meter 162 and the second transfer pressurized flow meter 163 are both connected to the control module 150.
