Description

Technical Field

[0001] This invention relates to the field of temperature control technology, specifically to temperature control methods, devices, computer equipment, and storage media. Background Technology

[0002] During normal operation, the printing press has high requirements for the ink's operating temperature. The optimal operating temperature range for ink is generally 28-32℃. When the temperature is too high, the ink is prone to evaporation and drying; when the temperature is too low, the ink's fluidity decreases. Both of these conditions will result in poor ink output from the printhead, affecting print quality. Continuous operation of the printing press will also cause the printhead circuit board temperature to rise, typically reaching around 60℃. Prolonged exposure to high temperatures will affect the printhead circuit board's performance and the printing effect. Therefore, temperature control of both the ink and the printhead circuit board is crucial.

[0003] Related technologies typically use fans to cool the ink and printhead circuit board separately, which is suitable for high-temperature environments, but not for both low-temperature and high-temperature environments, and cannot simultaneously meet the temperature control requirements of both the ink and the printhead circuit board.

[0004] Therefore, there is an urgent need for a temperature control method that is applicable to different external temperatures and can simultaneously meet the temperature control requirements of ink and printhead circuit boards. Summary of the Invention

[0005] Therefore, the technical problem to be solved by the present invention is to overcome the shortcomings of related technologies that are not applicable to different external temperatures and cannot simultaneously meet the temperature control requirements of ink and printhead boards.

[0006] To address the aforementioned technical problems, this invention provides a temperature control method applied to a printing machine, the printing machine including an ink cartridge and a printhead board, the printhead board being equipped with printheads, and the temperature control method comprising:

[0007] When the printing machine is in operation, determine whether the current temperature of the ink in the print head is less than or equal to the maximum value of the preset temperature range and greater than or equal to the minimum value of the preset temperature range.

[0008] When the current temperature of the ink in the printhead is greater than the maximum value of the preset temperature range, the temperature of the ink in the ink cartridge and the temperature of the printhead board are reduced according to the current temperature of the ink in the printhead; when the current temperature of the ink in the printhead is less than the minimum value of the preset temperature range, the temperature of the ink in the ink cartridge is increased according to the current temperature of the ink in the printhead, and the temperature of the printhead board is decreased, so as to control the temperature of the ink in the ink cartridge and the temperature of the printhead board to be within the normal operating temperature range.

[0009] In one optional implementation, when the current temperature of the ink in the printhead is greater than the maximum value of a preset temperature range, reducing the temperature of the ink in the ink cartridge and the temperature of the printhead circuit board based on the current temperature of the ink in the printhead includes:

[0010] When the current temperature of the ink in the printhead is greater than the maximum value of the preset temperature range, the difference between the current temperature of the ink in the printhead and the temperature of the temperature control medium in the temperature control circuit is determined; the first temperature of the temperature control medium in the temperature control circuit is determined based on the current temperature of the ink in the printhead and the difference between the current temperature of the ink in the printhead and the temperature of the temperature control medium in the temperature control circuit.

[0011] The temperature of the temperature control medium in the temperature control circuit is reduced to the first temperature to reduce the temperature of the ink in the ink cartridge and the temperature of the printhead board.

[0012] The temperature control circuit is used to control the temperature of the ink in the ink cartridge and the printhead circuit board.

[0014] When the current temperature of the ink in the printhead is less than the minimum value of the preset temperature range, the difference between the current temperature of the ink in the printhead and the temperature of the temperature control medium in the temperature control circuit is determined; the second temperature of the temperature control medium in the temperature control circuit is determined based on the current temperature of the ink in the printhead and the difference between the current temperature of the ink in the printhead and the temperature of the temperature control medium in the temperature control circuit.

[0015] The temperature of the temperature control medium in the temperature control circuit is increased to a second temperature to increase the temperature of the ink in the ink cartridge and decrease the temperature of the printhead board.

[0016] In an optional implementation, the method further includes:

[0017] When the current temperature of the ink inside the printhead is less than or equal to the maximum value of the preset temperature range and greater than or equal to the minimum value of the preset temperature range, determine whether the current temperature of the printhead board is less than or equal to the maximum value of the normal operating temperature range of the printhead board and greater than or equal to the minimum value of the normal operating temperature range of the printhead board.

[0018] When the current temperature of the printhead board is greater than the maximum value of the normal operating temperature range of the printhead board or less than the minimum value of the normal operating temperature range of the printhead board, determine the difference between the current temperature of the ink in the ink cartridge and the minimum value of the normal operating temperature range of the ink in the ink cartridge.

[0019] The temperature of the ink in the ink cartridge and the temperature of the printhead board are reduced based on the difference between the current temperature of the ink in the ink cartridge, the current temperature of the printhead board, and the minimum value of the normal operating temperature range of the ink in the ink cartridge, in order to control the temperature of the ink in the ink cartridge and the temperature of the printhead board to be within the normal operating temperature range.

[0020] In one optional implementation, reducing the temperature of the ink in the ink cartridge and the temperature of the printhead circuit board based on the difference between the current temperature of the ink in the ink cartridge, the current temperature of the printhead circuit board, the minimum value of the normal operating temperature range of the ink in the ink cartridge, and the minimum value of the normal operating temperature range of the ink in the ink cartridge includes:

[0021] The third temperature of the temperature control medium in the temperature control circuit is determined by the difference between the current temperature of the ink in the ink cartridge, the current temperature of the printhead board, the current temperature of the ink in the ink cartridge, and the minimum value of the normal operating temperature range of the ink in the ink cartridge.

[0022] The temperature of the temperature control medium in the temperature control circuit is reduced to the third temperature to lower the temperature of the ink in the ink cartridge and the temperature of the printhead board.

[0023] Secondly, the present invention provides a temperature control device applied to a printing machine, the printing machine including an ink cartridge and a printhead board, the printhead board being provided with printheads, and the temperature control device comprising:

[0026] The first temperature sensor is installed inside the printhead and connected to the temperature controller to detect the current temperature of the ink inside the printhead;

[0027] The outlet of the temperature controller is connected to the first temperature control pipe, and the return outlet of the temperature controller is connected to the second temperature control pipe.

[0028] In one optional embodiment, the temperature controller, the first temperature control pipe, and the second temperature control pipe form a temperature control loop, and a temperature control medium is present in the temperature control loop. The temperature controller is used to heat or cool the temperature control medium according to the current temperature of the ink in the printhead detected by the first temperature sensor.

[0029] In one optional embodiment, the temperature control device further includes: a second temperature sensor and a third temperature sensor;

[0030] The second temperature sensor is disposed on the outer surface of the ink cartridge and connected to the temperature controller to detect the current temperature of the ink inside the ink cartridge;

[0031] The third temperature sensor is disposed on the surface of the nozzle board and connected to the temperature controller to detect the current temperature of the nozzle board.

[0034] Fifthly, the present invention provides a computer program product, including computer instructions, which are used to cause a computer to execute the SAR method for simulating complex moving targets on the sea surface in a composite scene as described in the first aspect or any of its corresponding embodiments.

[0035] The technical solution provided by this invention has the following technical effects:

[0036] In this embodiment of the invention, when the printing machine is in operation, the current temperature of the ink inside the printhead can be determined to be within the normal operating temperature range by checking whether the current temperature is less than or equal to the maximum value of a preset temperature range and greater than or equal to the minimum value of the preset temperature range. If the current temperature is not within the normal operating temperature range, but is greater than the maximum value of the preset temperature range, it indicates that the current temperature is too high. In this case, the temperature of the ink in the cartridge and the printhead circuit board can be lowered based on the current ink temperature. If the current temperature is less than the minimum value of the preset temperature range, it indicates that the current temperature is too low. In this case, the temperature of the ink in the cartridge can be increased, and the temperature of the printhead circuit board can be decreased, thereby controlling the temperature of both the ink in the cartridge and the printhead circuit board within the normal operating temperature range. This method is applicable to different external temperatures and simultaneously achieves temperature control of both the ink in the cartridge and the printhead circuit board.

[0045] Furthermore, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0046] Figure 1 This is a schematic flowchart of a temperature control method according to an embodiment of the present invention.

[0047] like Figure 1 As shown in the embodiment of the present invention, a temperature control method provided by the present invention is applied to a printing machine. The printing machine includes an ink cartridge and a printhead board. The printhead board is equipped with printheads. The temperature control method includes:

[0048] S101: When the printing machine is in operation, determine whether the current temperature of the ink in the printhead is less than or equal to the maximum value of the preset temperature range and greater than or equal to the minimum value of the preset temperature range.

[0049] In this embodiment, when the printing machine is in operation, it can be determined whether the current temperature of the ink in the printhead is within the preset temperature range by determining whether the current temperature of the ink in the printhead is less than or equal to the maximum value of the preset temperature range and greater than or equal to the minimum value of the preset temperature range. The preset temperature range can be determined based on the normal operating temperature range of the ink in the ink cartridge and the normal operating temperature range of the printhead board, or it can be the normal operating temperature range of the ink in the printhead.

[0050] In this embodiment, there is no specific limitation on the type of printing machine to which the temperature control method is applied. As an example, the printing machine to which the temperature control method is applied can be a digital printing machine.

[0051] S102: When the current temperature of the ink in the printhead is greater than the maximum value of the preset temperature range, the temperature of the ink in the ink cartridge and the temperature of the printhead board are reduced according to the current temperature of the ink in the printhead. When the current temperature of the ink in the printhead is less than the minimum value of the preset temperature range, the temperature of the ink in the ink cartridge is increased according to the current temperature of the ink in the printhead, and the temperature of the printhead board is decreased, so as to control the temperature of the ink in the ink cartridge and the temperature of the printhead board to be within the normal operating temperature range.

[0052] In this embodiment, when the current temperature of the ink inside the printhead is not within the normal operating temperature range, if the current temperature of the ink inside the printhead is greater than the maximum value of the preset temperature range, it indicates that the current temperature of the ink inside the printhead is high. In this case, the temperature of the ink in the ink cartridge and the temperature of the printhead circuit board can be reduced based on the current temperature of the ink inside the printhead. If the current temperature of the ink inside the printhead is less than the minimum value of the preset temperature range, it indicates that the current temperature of the ink inside the printhead is low. In this case, the temperature of the ink in the ink cartridge can be increased based on the current temperature of the ink inside the printhead, and the temperature of the printhead circuit board can be decreased to control the temperature of the ink in the ink cartridge and the temperature of the printhead circuit board within the normal operating temperature range. The technical solution of this invention can be applied to different external temperatures, simultaneously achieving temperature control of both the ink in the ink cartridge and the printhead circuit board.

[0053] In this embodiment, the normal operating temperature range of the ink in the ink cartridge can be set as a first temperature range [A1, A2], and the normal operating temperature range of the printhead board can be set as a second temperature range [B1, B2].

[0054] In this embodiment, considering that the normal operating temperature range of ink is generally 28-32℃, and the temperature of the printhead board is around 60℃ when it is working, the temperature difference is quite large. Therefore, whether the temperature of the ink in the ink cartridge is lowered or raised, it will always be lowering the temperature of the printhead board.

[0055] In an optional implementation, step S102, when the current temperature of the ink inside the printhead is greater than the maximum value of a preset temperature range, involves reducing the temperature of the ink in the ink cartridge and the temperature of the printhead circuit board based on the current temperature of the ink inside the printhead. Specifically, this includes:

[0056] Sa1: When the current temperature of the ink inside the printhead is greater than the maximum value of the preset temperature range, determine the difference between the current temperature of the ink inside the printhead and the temperature of the temperature control medium in the temperature control circuit. Determine the first temperature of the temperature control medium in the temperature control circuit based on the difference between the current temperature of the ink inside the printhead and the temperature of the temperature control medium in the temperature control circuit.

[0057] Sa2: Reduces the temperature of the temperature control medium in the temperature control circuit to the first temperature, thereby reducing the temperature of the ink in the ink cartridge and the temperature of the printhead board.

[0058] In this embodiment, the temperature control circuit is used to control the temperature of the ink in the ink cartridge and the printhead circuit board.

[0059] In this embodiment, the temperature of both the ink in the ink cartridge and the printhead circuit board can be simultaneously controlled via a temperature control loop. In this embodiment, a first prediction relationship can be obtained through training. This first prediction relationship characterizes the relationship between the current temperature of the ink in the printhead, the temperature of the temperature control medium in the temperature control loop, the difference between the current temperature of the ink in the printhead and the temperature of the temperature control medium in the temperature control loop, the cooling time, and the first temperature holding time. The cooling time characterizes the time required to lower the temperature of the temperature control medium in the temperature control loop to the first temperature, and the first temperature holding time characterizes the time the temperature of the temperature control medium in the temperature control loop remains at the first temperature. In this embodiment, the first temperature, cooling time, and first temperature holding time of the temperature control medium in the temperature control loop can be determined based on the first prediction relationship, and control can be performed based on the determined first temperature, cooling time, and first temperature holding time of the temperature control medium in the temperature control loop.

[0060] In this embodiment, the temperature of the ink inside the printhead, the temperature of the ink cartridge, and the temperature of the printhead circuit board can be monitored in real time.

[0061] In an optional implementation, step S102, when the current temperature of the ink inside the printhead is less than the minimum value of a preset temperature range, involves increasing the temperature of the ink in the ink cartridge and decreasing the temperature of the printhead circuit board based on the current temperature of the ink inside the printhead. Specifically, this includes:

[0062] Sb1: When the current temperature of the ink inside the printhead is less than the minimum value of the preset temperature range, determine the difference between the current temperature of the ink inside the printhead and the temperature of the temperature control medium in the temperature control circuit. Determine the second temperature of the temperature control medium in the temperature control circuit based on the difference between the current temperature of the ink inside the printhead and the temperature of the temperature control medium in the temperature control circuit.

[0063] Sb1: Increases the temperature of the temperature control medium in the temperature control circuit to the second temperature, thereby increasing the temperature of the ink in the ink cartridge and reducing the temperature of the printhead board.

[0064] In this embodiment, a second prediction relationship can be obtained through training. This second prediction relationship characterizes the relationship between the current temperature of the ink in the printhead, the temperature of the temperature control medium in the temperature control loop, the difference between the current temperature of the ink in the printhead and the temperature of the temperature control medium in the temperature control loop, the heating time, and the second temperature holding time. The heating time characterizes the time required to raise the temperature of the temperature control medium in the temperature control loop to the second temperature, and the second temperature holding time characterizes the time required for the temperature of the temperature control medium in the temperature control loop to remain at the second temperature. In this embodiment, the second temperature, heating time, and second temperature holding time of the temperature control medium in the temperature control loop can be determined based on the second prediction relationship, and control can be performed based on the determined second temperature, heating time, and second temperature holding time of the temperature control medium in the temperature control loop.

[0065] In one optional implementation, the temperature control method further includes:

[0066] Sc1: When the current temperature of the ink inside the printhead is less than or equal to the maximum value of the preset temperature range and greater than or equal to the minimum value of the preset temperature range, determine whether the current temperature of the printhead board is less than or equal to the maximum value of the normal operating temperature range of the printhead board and greater than or equal to the minimum value of the normal operating temperature range of the printhead board.

[0067] Sc2: When the current temperature of the printhead board is greater than the maximum value of the normal operating temperature range of the printhead board or less than the minimum value of the normal operating temperature range of the printhead board, determine the difference between the current temperature of the ink in the ink cartridge and the minimum value of the normal operating temperature range of the ink in the ink cartridge.

[0068] Sc3: Based on the difference between the current temperature of the ink in the ink cartridge, the current temperature of the printhead board, and the minimum value of the normal operating temperature range of the ink in the ink cartridge, reduce the temperature of the ink in the ink cartridge and the temperature of the printhead board to control the temperature of the ink in the ink cartridge and the temperature of the printhead board to be within the normal operating temperature range.

[0069] In this embodiment, considering that when the printing machine is in operation, the temperature of the printhead circuit board is less likely to be within its normal operating temperature range than the temperature of the ink inside the printhead and the ink cartridge, it is necessary to determine whether the current temperature of the printhead circuit board is within its normal operating temperature range when the temperature of the ink inside the printhead is within a preset temperature range. If the current temperature of the printhead circuit board is not within its normal operating temperature range, the difference between the current temperature of the ink inside the ink cartridge and the minimum value of its normal operating temperature range is determined. The temperatures of both the ink inside the ink cartridge and the printhead circuit board can be reduced based on this difference. Simultaneously, the temperatures of both the ink inside the ink cartridge and the printhead circuit board are controlled to remain within their normal operating temperature ranges.

[0070] In one optional implementation, Sc3 reduces the temperature of the ink in the ink cartridge and the temperature of the printhead board based on the difference between the current temperature of the ink in the ink cartridge, the current temperature of the printhead board, the minimum value of the normal operating temperature range of the ink in the ink cartridge, specifically including:

[0071] The third temperature of the temperature control medium in the temperature control circuit is determined by the difference between the current temperature of the ink in the ink cartridge, the current temperature of the printhead board, the current temperature of the ink in the ink cartridge, and the minimum value of the normal operating temperature range of the ink in the ink cartridge.

[0072] The temperature of the temperature control medium in the temperature control circuit is reduced to the third temperature to lower the temperature of the ink in the ink cartridge and the temperature of the printhead board.

[0073] In this embodiment, a third prediction relationship can be obtained through training. This third prediction relationship characterizes the relationship between the current temperature of the ink in the ink cartridge, the current temperature of the printhead board, the difference between the current temperature of the ink in the ink cartridge and the minimum value of the normal operating temperature range of the ink in the ink cartridge, the third temperature of the temperature control medium in the temperature control loop, the cooling time, and the third temperature holding time. The cooling time characterizes the time required to lower the temperature of the temperature control medium in the temperature control loop to the third temperature, and the third temperature holding time characterizes the time required for the temperature of the temperature control medium in the temperature control loop to remain at the third temperature. In this embodiment, the third temperature, cooling time, and third temperature holding time of the temperature control medium in the temperature control loop can be determined based on the third prediction relationship, and control can be performed based on the determined third temperature, cooling time, and third temperature holding time of the temperature control medium in the temperature control loop.

[0074] It should be noted that the contents not described in detail in this specification are common knowledge to those skilled in the art.

[0075] This embodiment also provides a temperature control device for implementing the above embodiments and optional implementation methods, which will not be repeated hereafter. As used below, the term "module" can be a combination of software and / or hardware that implements a predetermined function. Although the system described in the following embodiments is preferably implemented in software, hardware implementation, or a combination of software and hardware, is also possible and contemplated.

[0076] Figure 2 This is a schematic diagram of the temperature control device according to an embodiment of the present invention.

[0077] This invention provides a temperature control device for use in a printing machine. The printing machine includes an ink cartridge and a printhead board, the printhead board being equipped with printheads, such as... Figure 2 As shown, the temperature control device includes:

[0078] The system comprises a first temperature control pipe 11, a second temperature control pipe 12, a first temperature sensor 13, and a temperature controller 14.

[0079] The first temperature control pipe 11 is disposed on the outer surface of the ink cartridge 15. The second temperature control pipe 12 is disposed on the surface of the printhead board 16. The first temperature control pipe 11 and the second temperature control pipe 12 are connected.

[0080] The first temperature sensor 13 is installed inside the printhead and connected to the temperature controller 14 to detect the current temperature of the ink inside the printhead.

[0081] The outlet of the temperature controller 14 is connected to the first temperature control pipe 11, and the return port of the temperature controller 14 is connected to the second temperature control pipe 12.

[0082] In this embodiment, the first temperature control pipe 11 may be provided with a first liquid inlet and a first liquid outlet. The second temperature control pipe 12 may be provided with a second liquid inlet and a second liquid outlet. The first liquid inlet of the first temperature control pipe 11 may be connected to the liquid outlet of the temperature controller 14, and the first liquid outlet may be connected to the second liquid inlet of the second temperature control pipe 12. The second liquid outlet of the second temperature control pipe 12 may be connected to the return liquid outlet of the temperature controller 14. The first temperature control pipe 11 may be disposed between adjacent ink cartridges 15, and the sides of the first temperature control pipe 11 may all contact the outer surface of the adjacent ink cartridges 15. The first temperature control pipe 11 may be the same length as the ink cartridges 15. Both the first temperature control pipe 11 and the second temperature control pipe 12 may be water-cooled plates. As an example, both the first temperature control pipe 11 and the second temperature control pipe 12 may be aluminum profile water-cooled plates.

[0083] In one alternative embodiment, the temperature controller 14, the first temperature control pipe 11, and the second temperature control pipe 12 form a temperature control loop. A temperature control medium is present in the temperature control loop. The temperature controller 14 is used to heat or cool the temperature control medium according to the current temperature of the ink in the printhead detected by the first temperature sensor 13.

[0084] In this embodiment, the temperature control medium can be a liquid, specifically pure water, distilled water, automotive coolant, or thermal oil. Considering the low heat exchange efficiency of gases and the high gas consumption and cost associated with temperature control using gases, this invention does not use gas as the temperature control medium.

[0085] In one alternative embodiment, the temperature control device further includes a second temperature sensor and a third temperature sensor.

[0086] The second temperature sensor is located on the outer surface of the ink cartridge 15 and is connected to the temperature controller 14 to detect the current temperature of the ink inside the ink cartridge 15.

[0087] The third temperature sensor is installed on the surface of the nozzle board 16 and connected to the temperature controller 14 to detect the current temperature of the nozzle board 16.

[0088] In this embodiment, when the printing machine is in operation, the first temperature sensor 13 can detect the current temperature of the ink in the printhead in real time, the second temperature sensor can detect the current temperature of the ink in the ink cartridge 15 in real time, and the third temperature sensor can detect the current temperature of the printhead board 16 in real time.

[0089] In this embodiment, the temperature control device may further include a heat sink; the heat sink may be disposed between the second temperature control pipe 12 and the nozzle board 16. The heat sink may be used to realize heat exchange between the nozzle board 16 and the second temperature control pipe 12, and may also separate the nozzle board 16 from the second temperature control pipe 12 to prevent damage or breakage of the second temperature control pipe 12, thereby damaging the nozzle board 16.
