Description

Technical Field

[0001] This invention relates to the field of inkjet printing technology, specifically to an ink cartridge temperature control device and its working method. Background Technology

[0002] Currently, printers are increasingly widely used as the primary equipment for digital printing. However, the drop in ambient temperature during winter leads to a significant increase in ink viscosity and a decrease in the solubility and affinity of ink components, often greatly affecting inkjet performance. Mild effects include unstable ink output, slower droplet impact speed, and droplet deviation (slanted spraying), as well as ink pooling on the medium (ineffective spreading). More severe effects include the printhead failing to eject ink droplets or ink interruption during printing.

[0003] Therefore, ensuring stable inkjet printing by overcoming inkjet printing defects caused by temperature has become an important issue. In existing technologies, the ink cartridges are heated by setting up a temperature control device inside the inkjet printer. However, the problem is that the temperature control effect of the device is not ideal. It can only heat the ink cartridges but cannot dissipate heat from the inside of the device. The internal components of the device work at high temperatures for a long time, which increases the maintenance rate and maintenance cost. Moreover, most temperature control devices have complex structures and are very troublesome to install and disassemble, which is not conducive to later inspection and maintenance. Summary of the Invention

[0013] As a preferred embodiment of the present invention, a tightening hole is provided on one side of the surface of the control plate, and the inner wall of the tightening hole is threaded. The tightening hole and the tightening bolt cooperate with each other to tighten the control plate.

[0014] As a preferred embodiment of the present invention, a strip groove is provided on one side of the surface of the fan mounting plate, the strip groove allowing the ink inlet at the top of the ink cartridge to pass through, and a connecting groove is provided on one side of the strip groove, through which the top of the wire connector is located outside the fan mounting plate.

[0015] As a preferred embodiment of the present invention, a fixing strip is provided on one side of the surface of the fan mounting plate, and a limiting tooth is provided on one side of the fixing strip, the number of the limiting tooth being equal to the number of the ink sacs.

[0017] As a preferred embodiment of the present invention, the fixing strip has first fixing holes at both ends, and the fan mounting plate has a second fixing hole on its top surface that cooperates with the first fixing holes. The fan mounting plate and the fixing strip are connected by screws.

[0018] A method for operating an ink sac temperature control device includes the following steps:

[0019] Step A, Install the fixing components: Connect the insert at the bottom of the mounting rod to the threaded hole on the surface of the printhead mounting base. Use screws to pass through the first limiting hole on the top surface of the mounting rod and the second limiting hole on the surface of the heat sink fixing plate in sequence, tighten the screws to fix the position of the heat sink fixing plate, and insert the ink cartridge into the printhead through the through groove on the surface of the heat sink fixing plate.

[0020] Step B, Install the temperature control components: Fix the heat sink shell to the surface of the heat sink mounting plate, so that the ink bag passes through the heat dissipation space formed between the two heat sink plates, place the heating element on one side of the surface of the heat sink shell, install the cooling fan on one side of the fan mounting plate, and connect the other side of the fan mounting plate to the top of the heat sink shell.

[0021] Step C, Install the control components: Insert both ends of the control board into the first slide groove from top to bottom, tighten the control board by passing the tightening bolts through the tightening holes, insert the sliding strips at both ends of the control panel into the second slide groove, press the control panel to make the second strip engage with the internal space formed by the first strip and the second slide groove, and fix the position of the control panel.

[0022] Step D: Temperature control of the ink cartridge: The temperature sensor monitors the internal temperature of the device and sends the monitored temperature signal to the control board. When the ink cartridge temperature is lower than the preset temperature, the control board activates the heating element, which raises the temperature of the heating element. The heat is transferred to the ink cartridge through the heat sink to heat the ink cartridge until the preset temperature is reached and the ink cartridge temperature is kept constant. When heat dissipation is required inside the device, the control board activates the cooling fan, which accelerates the air circulation inside the device to achieve the heat dissipation effect until the internal temperature of the device reaches the preset temperature and the internal temperature of the device is kept constant.

[0023] Compared with the prior art, the beneficial effects of the present invention are:

[0024] 1. The temperature control component designed in this invention includes a heat dissipation shell, inside which are equidistantly distributed heat dissipation plates. Both the heat dissipation shell and the heat dissipation plates are made of aluminum and are fitted to the periphery of the ink cartridge. A heating element is placed on one side of the surface of the heat dissipation shell. Utilizing the chemical characteristic of aluminum's rapid heat transfer, the ink cartridge is rapidly heated. Simultaneously, when the internal temperature of the device exceeds a preset temperature, the heat dissipation shell, heat dissipation plates, and cooling fan work together to achieve rapid heat dissipation. This invention not only rapidly heats the ink cartridge but also rapidly dissipates heat from the inside of the device, preventing the lifespan of internal components from being affected by prolonged high internal temperatures, thus truly achieving the technical effect of temperature control.

[0025] 2. The control board of this invention is slidably connected to the heat sink and then tightened by a tightening bolt, thus fixing the position of the control board. The control panel is snapped into the heat sink, and the position of the control panel is fixed by the cooperation of the first and second locking strips. This makes the disassembly and installation of the control components and the temperature control components very convenient. At the same time, the ink cartridge is located inside the heat sink, the heating element is pasted on one side of the heat sink, and the cooling fan is installed on one side of the heat sink via an L-shaped fan mounting plate. This achieves the technical effect of temperature control of the entire device, while also achieving a simple overall structure, convenient disassembly and installation, easy later inspection and maintenance, and reduced maintenance costs.

[0026] The above description is merely an overview of the technical solution of the present invention. In order to better understand the technical means of the present invention and to implement it in accordance with the contents of the specification, and in order to make the above and other objects, features and advantages of the present invention more apparent and understandable, specific embodiments of the present invention are described below.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0036] Example 1:

[0040] Temperature control component 2 includes a heat sink 201, which is located directly above the heat sink fixing plate 103.

[0041] Specifically, such as Figures 1-3 As shown, the first slide groove 204 is used to connect with the control board 301, the second slide groove 205 is used to connect with the control panel 303, the mounting groove 203 is used to install the control board 301, the inner wall of the heat dissipation space formed between any two heat dissipation plates 202 is in close contact with the periphery of the ink bag 105, the heat dissipation shell 201 and the heat dissipation plate 202 are both made of aluminum, the heating element 209 is set on one side of the surface of the heat dissipation shell 201, and the rapid heating of the ink bag 105 is achieved by utilizing the chemical characteristic of aluminum's fast heat transfer speed. The cooling fan 208 is installed on one side of the heat dissipation shell 201 through the L-shaped fan mounting plate 207. The rapid heat dissipation effect inside the device is achieved through the cooperation of the heat dissipation shell 201, the heat dissipation plate 202 and the cooling fan 208. When installing the cooling fan 208, a certain gap is maintained between the cooling fan 208 and the heating element 209 to facilitate air circulation and further improve the heat dissipation effect.

[0042] The control component 3 includes a control board 301. Both sides of the control board 301 are slidably connected to the first slide groove 204. A wire connector 302 is provided on the top of the control board 301. A control panel 303 is provided on one side of the control panel 301. A sliding strip 304 is provided on the side of the control panel 303 that is connected to the heat sink 201. A second locking strip 305 is provided on one side of the sliding strip 304. The sliding strip 304 is slidably connected to the second slide groove 205. The second locking strip 305 is adapted to the first locking strip 206.

[0043] Specifically, such as Figure 1 , Figure 2 , Figure 4As shown, the control panel 303 is adapted to the control board 301. The surface of the control panel 303 has holes and slots for the operation of the switch. The control board 301 realizes the communication control of the present invention. The two ends of the control board 301 are inserted into the first slide groove 204 from top to bottom. The control board 301 is tightened by passing a tightening bolt through the tightening hole. The position of the control board 301 is fixed to avoid the problem of poor contact caused by the loosening of the control board 301. The two ends of the control panel 303 are inserted into the second slide groove 205 from top to bottom. The control panel 303 is pressed so that the second locking strip 305 is inserted into the internal space formed by the first locking strip 206 and the second slide groove 205, fixing the position of the control panel 303. The control panel 303 is engaged with the side of the heat sink 201 away from the heating element 209, which facilitates the disassembly and installation of the control panel 303.

[0044] In this embodiment, the nozzle mounting base 101 is connected to the heat sink mounting plate 103 via the mounting rod 106. The bottom of the mounting rod 106 is provided with an insertion rod, the outer surface of which is threaded, and the top surface of the mounting rod 106 is provided with a first limiting hole.

[0045] Specifically, such as Figure 1 As shown, the mounting rod 106 is made of copper. In this embodiment, the mounting rod 106 is hexagonal prism in shape. The insert at the bottom of the mounting rod 106 is used to connect with the nozzle mounting base 101, and the first limiting hole at the top of the mounting rod 106 is used to connect with the heat sink mounting plate 103.

[0046] In this embodiment, the surface of the nozzle fixing base 101 is provided with a threaded hole that matches the insertion rod, and the surface of the heat sink fixing plate 103 is provided with a second limiting hole that matches the first limiting hole. The inner walls of both the first limiting hole and the second limiting hole are provided with threads.

[0047] Specifically, such as Figure 1 As shown, when connecting the nozzle mounting base 101 and the mounting rod 106, the connection can be achieved by inserting the rod into the threaded hole and tightening it. When connecting the heat sink mounting plate 103 and the mounting rod 106, the position of the heat sink mounting plate 103 can be fixed by screwing the screw into the first limiting hole and the second limiting hole.

[0048] In this embodiment, a temperature sensor is provided on one side of the control board 301. The signal output terminal of the temperature sensor is communicatively connected to the signal receiving terminal of the control board 301. The signal output terminal of the control board 301 is communicatively connected to the signal receiving terminal of the cooling fan 208 and the signal receiving terminal of the heating element 209, respectively.

[0049] Specifically, such as Figure 6As shown, the temperature sensor is used to monitor the internal temperature of the device and transmits the monitored temperature signal to the control board 301. The control board 301 controls the start and stop of the cooling fan 208 and the heating element 209. When the ink cartridge 105 needs to be heated, the control board 301 starts the heating element 209, which heats the heat sink 201. The heat sink 201 then transfers the heat to the ink cartridge 105, achieving the technical effect of heating the ink cartridge 105. Since maintaining a high temperature inside the device for a long time will affect the service life of the internal components, after use, when the temperature sensor detects that the internal temperature of the device is higher than the preset temperature, the control board 301 controls the cooling fan 208 to start. The high-speed rotating cooling fan 208 works in conjunction with the heat sink 201 and the heat sink 202 to achieve rapid heat dissipation inside the device, ensuring the service life of the device and reducing the later maintenance rate and maintenance costs.

[0050] In this embodiment, a tightening hole is provided on one side of the surface of the control plate 301, and the inner wall of the tightening hole is threaded. The tightening hole and the tightening bolt cooperate with each other to tighten the control plate 301.

[0051] Specifically, in this invention, in order to facilitate the disassembly and installation of the control board 301, the control board 301 is slidably connected to the heat sink 201. Since there is a certain gap between the two ends of the control board 301 and the first sliding groove 204, the control board 301 may become loose during application. In order to prevent the control board 301 from becoming loose during use, a tightening bolt and a tightening hole are used to fix the position of the control board 301 and avoid the adverse effects caused by the loosening of the control board 301.

[0052] In this embodiment, a strip groove 2010 is provided on one side of the surface of the fan mounting plate 207. The strip groove 2010 allows the ink inlet at the top of the ink cartridge 105 to pass through. A connecting groove is provided on one side of the strip groove 2010, and the top of the wire connector 302 is located outside the fan mounting plate 207 through the connecting groove.

[0053] Specifically, such as Figures 1-2 As shown, the strip groove 2010 is used to place the ink inlet of the ink sac 105 on the outside, which is convenient for refilling ink later. The connecting groove is used to place the wire connector 302 on the outside, which is convenient for connecting the various components in the device.

[0054] In this embodiment, a fixing strip 2011 is provided on one side of the surface of the fan mounting plate 207, and a limiting tooth 20110 is provided on one side of the fixing strip 2011. The number of limiting teeth 20110 is equal to the number of ink sacs 105.

[0055] Specifically, such as Figures 1-2As shown, the fixing strip 2011 is used to fix the position of the ink sac 105, and the position and number of the limiting teeth 20110 correspond one-to-one with the position and number of the ink sac 105.

[0056] In this embodiment, the limiting tooth 20110 is L-shaped, and the plane at the bottom of the end of the limiting tooth 20110 away from the fixing strip 2011 is lower than the plane at the bottom of the fixing strip 2011.

[0057] Specifically, such as Figures 1-2 As shown, the fixing strip 2011 is detachably connected to one side of the surface of the fan mounting plate 207. The lower end of the limiting tooth 20110 presses against the top surface of the ink sac 105 to fix the position of the ink sac 105 and prevent the ink sac 105 from shaking significantly during use, thus affecting the performance.

[0058] In this embodiment, both ends of the fixing strip 2011 are provided with first fixing holes 20111, and the top surface of the fan mounting plate 207 is provided with a second fixing hole that cooperates with the first fixing holes 20111. The fan mounting plate 207 and the fixing strip 2011 are connected by screws.

[0059] Specifically, such as Figures 1-2 As shown, by passing screws through the first fixing hole 20111 and the second fixing hole in sequence and tightening the screws, the position of the fixing strip 2011 can be fixed. With the cooperation of the screws, the first fixing hole 20111 and the second fixing hole, the removal and installation of the fixing strip 2011 are very convenient.

[0060] Example 2:

[0061] A method for operating an ink sac temperature control device includes the following steps:

[0062] Step A, Install the fixing components: Thread the insert at the bottom of the mounting rod 106 to the threaded hole on the surface of the printhead fixing seat 101. Use screws to pass through the first limiting hole on the top surface of the mounting rod 106 and the second limiting hole on the surface of the heat sink fixing plate 103 in sequence, tighten the screws to fix the position of the heat sink fixing plate 103, and insert the ink sac 105 into the printhead 102 through the through groove 104 on the surface of the heat sink fixing plate 103.

[0063] Step B, Install the temperature control components: Fix the heat sink 201 to the surface of the heat sink fixing plate 103, so that the ink bag 105 passes through the heat dissipation space formed between the two heat sinks 202, place the heating element 209 on one side of the surface of the heat sink 201, install the cooling fan 208 on one side of the fan mounting plate 207, and connect the other side of the fan mounting plate 207 to the top of the heat sink 201.

[0064] Specifically, holes are made at the top corner of the heat sink 201 and on the surface of the heat sink fixing plate 103, and bolts are used to fix the position between the heat sink 201 and the heat sink fixing plate 103.

[0065] Step C, Install the control components: Insert both ends of the control plate 301 into the first slide groove 204 from top to bottom, tighten the control plate 301 by passing the tightening bolts through the tightening holes, insert the sliding strips 304 at both ends of the control panel 303 into the second slide groove 205, press the control panel 303 so that the second locking strip 305 is inserted into the internal space formed by the first locking strip 206 and the second slide groove 205, and fix the position of the control panel 303;

[0066] Specifically, two protruding strips 2012 are provided on the side where the heat sink 201 connects to the control panel 303. The protruding strips 2012 are provided to facilitate the disassembly of the control panel 303. After the control panel 303 is connected to the heat sink 201, press the control panel 303 towards the mounting groove 203. Under the action of the two protruding strips 2012, the two ends of the control panel 303 are raised, forming a certain gap with the heat sink 201. Insert one end of a screwdriver into the gap and pry the control panel 303 up to complete the disassembly of the control panel 303.

[0067] Step D, temperature control of the ink cartridge: The temperature sensor monitors the internal temperature of the device and sends the monitored temperature signal to the control board 301. When the temperature of the ink cartridge 105 is lower than the preset temperature, the control board 301 activates the heating element 209. The temperature of the heating element 209 rises, and the heat is transferred to the ink cartridge 105 through the heat sink 201 to heat the ink cartridge 105 until the preset temperature is reached. The temperature of the ink cartridge 105 is then kept constant. When it is necessary to dissipate heat inside the device, the control board 301 activates the cooling fan 208. The cooling fan 208 accelerates the air circulation inside the device, thereby achieving the technical effect of heat dissipation, until the temperature inside the device reaches the preset temperature and is kept constant.

[0068] It should be noted that the specific models and specifications of the cooling fan 208, heating element 209, control board 301, and temperature sensor need to be selected and determined based on the actual specifications of the device. The specific selection and calculation method adopts the existing technology in this field, so it will not be described in detail here.

[0069] The power supply and operating principle of the cooling fan 208, heating element 209, control board 301, and temperature sensor are clear to those skilled in the art and will not be described in detail here.

[0070] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
