Description

Technical Field

[0001] This invention relates to the field of printer control technology, and more particularly to a heating control method for a printer, a printer, and a computer-readable storage medium. Background Technology

[0002] When a printer is first turned on or restarted after a long period of standby, the heated roller often needs to reach the required operating temperature as quickly as possible. Currently, some printers require a longer heating time for their heated rollers, often necessitating an increase in the heating power. However, increasing the heating power of the heated roller requires a corresponding increase in the total power consumption of the printer's power supply, leading to a corresponding increase in the size and cost of the power supply. Summary of the Invention

[0003] The purpose of this invention is to at least solve one of the technical problems existing in the prior art, and to provide a heating control method for a printer, a printer and a computer-readable storage medium, which can shorten the heating time of the heating roller without increasing the total power supply.

[0004] In a first aspect, embodiments of the present invention provide a heating control method for a printer, wherein the printer's load includes a heating roller, a print head, and several motors, and the heating roller is provided with a first coil and a second coil; the method includes:

[0005] Obtain the printhead operating power, motor operating power, and total power supply power;

[0006] The current remaining power is obtained based on the printhead operating power, the motor operating power, and the total power supply.

[0007] The heating power of the first coil and the second coil is controlled according to the current remaining power;

[0008] in:

[0009] The sum of the rated power of the heating roller, the rated power of the print head, and the rated power of all the motors is greater than the total power of the power supply; the rated power of the heating roller is the sum of the rated power of the first coil and the rated power of the second coil.

[0010] The printer heating control method provided by the embodiments of the present invention has at least the following beneficial effects: by setting dual coils inside the heating roller, namely a first coil and a second coil, the maximum heating power of the heating roller is increased; after adding coils to the heating roller, the sum of the rated power of the heating roller, the rated power of the print head, and the rated power of all motors is greater than the total power of the power supply, that is, the sum of the rated power of all loads of the printer is greater than the total power supply; at this time, by taking the print head operating power, the motor operating power, and the total power supply, and calculating the current remaining power based on the print head operating power, the motor operating power, and the total power supply, the heating power of the first coil and the second coil is controlled based on the current remaining power; the printer heating control method provided by the embodiments of the present invention can maximize the use of the printer's current remaining power to heat the heating roller, for example, when the printer is first turned on or restarted after a long period of standby, the power supply freed up by the print head and motor not needing to work is used for heating, which can increase the heating power of the heating roller and shorten the heating time of the heating roller without increasing the total power supply.

[0011] In some embodiments of the present invention, the heating control method, wherein controlling the heating power of the first coil and the second coil based on the current remaining power, includes:

[0012] When the current remaining power is less than the rated power of the first coil, the first coil is controlled to heat with the current remaining power through PWM drive, and the second coil is controlled to stop working.

[0013] In this embodiment, the current remaining power is less than the rated power of the first coil, indicating that in the current operating state of the printer, other loads besides the heating roller occupy a large amount of power. The current remaining power is too small to drive the first coil and the second coil to heat at the same time. Therefore, the first coil is controlled to heat with the current remaining power by PWM drive, and the second coil is controlled to stop working to avoid the printer power supply being overloaded.

[0014] In some embodiments of the heating control method provided by the present invention, the step of controlling the heating power of the first coil and the second coil according to the current remaining power further includes:

[0015] When the current remaining power is greater than the rated power of the first coil and less than the rated power of the heating roller, the first coil and the second coil are heated simultaneously by PWM drive control, and the sum of the heating power of the first coil and the heating power of the second coil is not greater than the current remaining power.

[0016] In this embodiment, the current remaining power is greater than the rated power of the first coil and less than the rated power of the heating roller. This indicates that, in the current operating state of the printer, other loads besides the heating roller occupy part of the power supply. The current remaining power can simultaneously drive the first coil and the second coil to perform heating work, thereby shortening the heating time. However, it cannot simultaneously drive the first coil and the second coil to operate at their rated power. Therefore, it is necessary to control the sum of the heating power of the first coil and the heating power of the second coil to not exceed the current remaining power to avoid overloading the printer power supply.

[0017] In some embodiments of the heating control method provided by the present invention, the step of controlling the heating power of the first coil and the second coil according to the current remaining power further includes:

[0018] When the current remaining power is greater than the rated power of the heating roller, the first coil and the second coil are heated simultaneously by PWM drive control, and the sum of the heating power of the first coil and the heating power of the second coil is not greater than the rated power of the heating roller.

[0019] In this embodiment, the current remaining power is greater than the rated power of the heating roller, indicating that in the current operating state of the printer, other loads besides the heating roller occupy less power. The current remaining power is large enough to drive both the first coil and the second coil to operate at their rated power, thereby shortening the heating time. In addition, it is necessary to control the heating power of the first coil and the sum of the heating power of the second coil to not exceed the rated power of the heating roller to avoid overloading the heating roller and causing the temperature to be too high.

[0020] In the heating control method provided in some embodiments of the present invention, the current remaining power is calculated by subtracting the printhead operating power and the total motor operating power from the total power of the power supply.

[0021] In some embodiments of the present invention, the heating control method, wherein controlling the heating power of the first coil and the second coil based on the current remaining power, includes:

[0022] Obtain the current heating power requirement;

[0023] When the current remaining power is greater than the current heating demand power, the heating power of the first coil and the second coil is controlled according to the current heating demand power, and the sum of the heating power of the first coil and the heating power of the second coil is not greater than the current heating demand power.

[0024] In this embodiment, when controlling the heating power of the first coil and the second coil, the current heating demand power is introduced as a control parameter. When the current remaining power is greater than the current heating demand power, the sum of the heating power of the first coil and the heating power of the second coil is controlled to not exceed the current heating demand power, so as to avoid wasting energy and causing the heating roller temperature to be too high.

[0025] In some embodiments of the heating control method provided by the present invention, the step of controlling the heating power of the first coil and the second coil according to the current remaining power further includes:

[0026] When the current remaining power is less than the current heating demand power, the heating power of the first coil and the second coil is controlled according to the current heating demand power, and the sum of the heating power of the first coil and the heating power of the second coil is not greater than the current remaining power.

[0027] In this embodiment, when the current remaining power is less than the current heating demand power, the heating power of the first coil and the sum of the heating power of the second coil can be controlled to not exceed the current remaining power, so as to avoid the printer power supply from being overloaded.

[0044] In the description of this invention, unless otherwise explicitly defined, terms such as "set up," "install," and "connect" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this invention in conjunction with the specific content of the technical solution.

[0045] This invention provides a heating control method for a printer, a printer, and a computer-readable storage medium, which can shorten the heating time of the heating roller without increasing the total power supply.

[0046] The embodiments of the present invention will be further described below with reference to the accompanying drawings.

[0047] Figure 1 This is a schematic diagram of the structure of the heating roller provided in an embodiment of the present invention. (Refer to...) Figure 1 The heating roller 100 includes a first coil 110, a second coil 120 and a fuse 130. One end of the fuse 130 is grounded and the other end is connected to one end of the first coil 110 and one end of the second coil 120 respectively. The other end of the first coil 110 and the other end of the second coil 120 are respectively connected to the heating roller drive circuit.

[0048] Reference Figure 2 A first aspect of the present invention provides a heating control method for a printer, wherein the load of the printer includes as follows: Figure 1 The heating roller 100, print head, and several motors are shown. The heating roller 100 is equipped with a first coil 110 and a second coil 120. The method includes, but is not limited to, steps S210 to S230:

[0049] Step S210: Obtain the printhead operating power, motor operating power, and total power supply;

[0050] Step S220: Obtain the current remaining power based on the printhead operating power, the motor operating power, and the total power of the power supply;

[0051] Step S230: Control the heating power of the first coil 110 and the second coil 120 according to the current remaining power;

[0052] in:

[0053] The sum of the rated power of the heating roller, the rated power of the print head, and the rated power of all the motors is greater than the total power of the power supply; the rated power of the heating roller is the sum of the rated power of the first coil 110 and the rated power of the second coil 120.

[0054] According to the printer heating control method provided in the embodiments of the present invention, the maximum heating power of the heating roller is increased by setting two coils inside the heating roller, namely a first coil 110 and a second coil 120. After adding coils to the heating roller, the sum of the rated power of the heating roller, the rated power of the print head, and the rated power of all motors is greater than the total power of the power supply, that is, the sum of the rated power of all loads of the printer is greater than the total power supply. At this time, the print head operating power, the motor operating power, and the total power supply are taken, and the current remaining power is calculated based on the print head operating power, the motor operating power, and the total power supply. Finally, the heating power of the first coil 110 and the second coil 120 is controlled based on the current remaining power. The printer heating control method provided in the embodiments of the present invention can make maximum use of the current remaining power of the printer to heat the heating roller. For example, when the printer is first turned on or restarted after a long period of standby, the power freed up by the print head and motor not working is used for heating. The heating power of the heating roller can be increased without increasing the total power supply, and the heating time of the heating roller can be shortened.

[0055] Reference Figure 3 In some embodiments of the heating control method provided by the present invention, Figure 2 Step S230, which controls the heating power of the first coil 110 and the second coil 120 based on the current remaining power, includes:

[0056] Step S231: When the current remaining power is less than the rated power of the first coil 110, the first coil 110 is heated with the current remaining power by PWM drive, and the second coil 120 is stopped working.

[0057] In this embodiment, the current remaining power is less than the rated power of the first coil 110, indicating that in the current operating state of the printer, other loads besides the heating roller occupy a large amount of power. The current remaining power is too small to simultaneously drive the first coil 110 and the second coil 120 to perform heating work. Therefore, the first coil 110 is controlled to heat with the current remaining power through PWM drive, and the second coil 120 is controlled to stop working to avoid overloading the printer power supply.

[0058] Reference Figure 3 In some embodiments of the heating control method provided by the present invention, Figure 2 Step S230, which controls the heating power of the first coil 110 and the second coil 120 based on the current remaining power, further includes:

[0059] Step S232: When the current remaining power is greater than the rated power of the first coil 110 and less than the rated power of the heating roller, the first coil 110 and the second coil 120 are heated simultaneously by PWM drive, and the sum of the heating power of the first coil 110 and the heating power of the second coil 120 is not greater than the current remaining power.

[0060] In this embodiment, the current remaining power is greater than the rated power of the first coil 110 and less than the rated power of the heating roller. This indicates that, in the current operating state of the printer, other loads besides the heating roller occupy part of the power supply. The current remaining power can simultaneously drive the first coil 110 and the second coil 120 to perform heating work, thereby shortening the heating time. However, it cannot simultaneously drive the first coil 110 and the second coil 120 to operate at their rated power. Therefore, it is necessary to control the sum of the heating power of the first coil 110 and the heating power of the second coil 120 to not exceed the current remaining power to avoid overloading the printer power supply.

[0061] Reference Figure 3 In some embodiments of the heating control method provided by the present invention, Figure 2 Step S230, which controls the heating power of the first coil 110 and the second coil 120 based on the current remaining power, further includes:

[0062] Step S233: When the current remaining power is greater than the rated power of the heating roller, the first coil 110 and the second coil 120 are heated simultaneously by PWM drive control, and the sum of the heating power of the first coil 110 and the heating power of the second coil 120 is not greater than the rated power of the heating roller.

[0063] In this embodiment, the current remaining power is greater than the rated power of the heating roller, indicating that in the current operating state of the printer, other loads besides the heating roller occupy less power. The current remaining power is large enough to simultaneously drive the first coil 110 and the second coil 120 to operate at their rated power, thereby shortening the heating time. In addition, it is necessary to control the sum of the heating power of the first coil 110 and the heating power of the second coil 120 to not exceed the rated power of the heating roller to avoid overloading the heating roller and causing the temperature to be too high.

[0064] In the heating control method provided in some embodiments of the present invention, the current remaining power is calculated by subtracting the printhead operating power and the total motor operating power from the total power of the power supply.

[0065] Reference Figure 4 In some embodiments of the heating control method provided by the present invention, Figure 2Step S230, which controls the heating power of the first coil 110 and the second coil 120 based on the current remaining power, includes:

[0066] Step S234: Obtain the current heating power requirement;

[0067] Step S235: When the current remaining power is greater than the current heating demand power, control the heating power of the first coil 110 and the second coil 120 according to the current heating demand power, and ensure that the sum of the heating power of the first coil 110 and the heating power of the second coil 120 is not greater than the current heating demand power.

[0068] In this embodiment, when controlling the heating power of the first coil 110 and the second coil 120, the current heating demand power is introduced as a control parameter. When the current remaining power is greater than the current heating demand power, the sum of the heating power of the first coil 110 and the heating power of the second coil 120 is controlled to be no greater than the current heating demand power, so as to avoid wasting energy and causing the heating roller temperature to be too high.

[0069] Reference Figure 4 In some embodiments of the heating control method provided by the present invention, Figure 2 Step S230, which controls the heating power of the first coil 110 and the second coil 120 based on the current remaining power, further includes:

[0070] Step S236: When the current remaining power is less than the current heating demand power, control the heating power of the first coil 110 and the second coil 120 according to the current heating demand power, and make the sum of the heating power of the first coil 110 and the heating power of the second coil 120 not greater than the current remaining power.

[0071] In this embodiment, when the current remaining power is less than the current heating demand power, the heating power of the first coil 110 and the heating power of the second coil 120 can be controlled to be no greater than the current remaining power, so as to avoid the printer power supply from being overloaded.

[0072] The heating control method of the present invention will be described below with a specific embodiment.

[0073] When printing, the print head and motor require 100W of power. Traditional heating rollers typically have a single heating wire with a heating power of 100W. Since the total power of a power supply is generally no less than 200W, there is a 100W power reserve when the printer is not printing. If this reserve power can be used to heat the heating roller, the heating time can be significantly shortened. Therefore, we designed the heating roller with a dual-coil structure: a single coil (100W) for printing and a dual-coil (200W) heating mode for non-printing, reducing heating time without increasing the power consumption. The specific heating control method is as follows:

[0074] The power consumed by the printhead is determined by the content printed by the user. The printhead operating power (Power_TPH) can be calculated from the printed content. The power of each motor can also be calculated, with the motor operating power being Power_Motor_n (n = 1, 2, 3, 4, 5, 6…). Therefore, the maximum power that the heating roller can consume (Power_Heater) is 200W – Power_TPH – Power_Motor_1 – ... – Power_Motor_n. When the heating roller needs heating, the maximum power that the heating roller can consume can be obtained by calculating the current power consumed by the printhead, the number of motors operating, and the power consumed by each motor. The maximum power of the heating roller is controlled by PWM drive to not exceed Power_Heater. In the embodiments of this invention, the control of the heating roller is not simply a matter of connecting one or two coils to control the heating power, but rather dynamically adjusting the maximum heating power of the heating roller based on the current power consumption of the printhead and motors, allowing for stepless adjustment between 0W and 200W.

[0075] Reference Figure 5 A second aspect of the present invention provides an operation control device 500, including a memory 520, a processor 510, and a computer program stored in the memory 520 and executable on the processor 510. The processor 510 executes the program to implement the heating control method described in the first aspect of the present invention, for example, by performing... Figure 2 Method steps S210 to S230, Figure 3 Method steps S210 to S233 or execution Figure 4 The method steps S210 to S236.

[0076] According to the printer operation control device 500 provided in the embodiment of the present invention, the maximum heating power of the heating roller is increased by setting two coils inside the heating roller, namely a first coil 110 and a second coil 120. After the heating roller is equipped with coils, the sum of the rated power of the heating roller, the rated power of the print head, and the rated power of all motors is greater than the total power of the power supply, that is, the sum of the rated power of all loads of the printer is greater than the total power supply. At this time, the print head operating power, the motor operating power, and the total power supply are taken, and the current remaining power is calculated based on the print head operating power, the motor operating power, and the total power supply. Finally, the heating power of the first coil 110 and the second coil 120 is controlled based on the current remaining power. The printer heating control method provided in the embodiment of the present invention can make maximum use of the current remaining power of the printer to heat the heating roller. For example, when the printer is first turned on or restarted after a long period of standby, the power freed up by the print head and motor not working is used for heating. The heating power of the heating roller can be increased without increasing the total power supply, and the heating time of the heating roller can be shortened.

[0077] In addition, a third aspect of the present invention provides a printer including the operation control device described in the second aspect of the present invention.

[0078] According to the embodiments of the present invention, the printer increases the maximum heating power of the heating roller by setting two coils inside the heating roller, namely a first coil 110 and a second coil 120. After adding coils to the heating roller, the sum of the rated power of the heating roller, the rated power of the print head, and the rated power of all motors is greater than the total power of the power supply, that is, the sum of the rated power of all loads of the printer is greater than the total power supply. At this time, by taking the print head operating power, the motor operating power, and the total power supply, and calculating the current remaining power based on the print head operating power, the motor operating power, and the total power supply, the heating power of the first coil 110 and the second coil 120 is controlled based on the current remaining power. The heating control method of the printer provided by the embodiments of the present invention can maximize the use of the printer's current remaining power to heat the heating roller. For example, when the printer is first turned on or restarted after a long period of standby, the power freed up by the print head and motor not needing to work is used for heating. This can increase the heating power of the heating roller and shorten the heating time of the heating roller without increasing the total power supply.

[0079] Furthermore, a fourth aspect of the present invention provides a computer-readable storage medium storing computer-executable instructions for causing a computer to perform the heating control method described in the first aspect of the present invention, for example, executing... Figure 2 Method steps S210 to S230, Figure 3Method steps S210 to S233 or execution Figure 4 The method steps S210 to S236.

[0080] According to the computer-readable storage medium provided in the embodiments of the present invention, the maximum heating power of the heating roller is increased by setting two coils inside the heating roller, namely a first coil 110 and a second coil 120. After the heating roller is equipped with coils, the sum of the rated power of the heating roller, the rated power of the print head, and the rated power of all motors is greater than the total power of the power supply, that is, the sum of the rated power of all loads of the printer is greater than the total power supply. At this time, the print head operating power, the motor operating power, and the total power supply are taken, and the current remaining power is calculated based on the print head operating power, the motor operating power, and the total power supply. Finally, the heating power of the first coil 110 and the second coil 120 is controlled based on the current remaining power. The printer heating control method provided in the embodiments of the present invention can make maximum use of the current remaining power of the printer to heat the heating roller. For example, when the printer is first turned on or restarted after a long period of standby, the power freed up by the print head and motor not working is used for heating. The heating power of the heating roller can be increased without increasing the total power supply, and the heating time of the heating roller can be shortened.
