Description

Technical Field

[0001] The utility model relates to a printer blade cleaning module, a printer cleaning unit including the same, and a printer device including the same. More specifically, it relates to a printer blade cleaning module, a printer cleaning unit including the same, and a printer device including the same, which can perform the entire cleaning process of a print head without manual intervention. Background Art

[0002] All DTF (Direct to Film) printers currently sold on the market do not yet have a function to automatically remove the ink attached to the blade after cleaning. Therefore, users face the trouble of manually wiping the ink attached to the blade with a wiper every time after cleaning. This process brings inconvenience to users, and some users sometimes ignore cleaning or do not clean at all due to this trouble.

[0003] The main disadvantages of the existing methods are reduced operating efficiency, increased labor costs, shortened blade life, and reduced print head quality. Generally, DTF printers need to be cleaned at least four times per period, but the number of cleanings varies depending on the site conditions and humidity, and the need to wipe the blade each time reduces operating efficiency.

[0004] If cleaning is neglected, the life of the print head will be shortened and the output quality will be reduced, which will reduce customer satisfaction. In addition, additional manpower is required to wipe the blade after cleaning, which will increase labor costs. Finally, wiping the blade with a wiper dipped in purified water will damage the blade surface, shortening the replacement cycle.

[0073] In addition, the following embodiments do not limit the protection scope of the present invention, but are only provided as examples, and there may be a variety of embodiments implemented by the present technical concept. Below, with reference to the accompanying drawings, the embodiments of the present invention are described in detail. In the drawings, the same reference numerals represent the same structural elements.

[0074] Overall structure of the printer device

[0075] Figure 1 The figure is a front view showing a printer device according to an embodiment of the present invention.

[0076] Reference Figure 1 The printer device 1000 generally includes the following main structural elements: a printing unit 1100, which is used to perform substantial printing; a cleaning unit 1200, which is used to clean the print head to prevent problems caused by ink used after printing, etc. remaining in the print head; and a supporting unit 1300, which is used to support the entire printing device, etc.

[0077] The printing unit 1100 uses DTP ink to print the design on the film. This is not a direct print on the clothes or fabric, but a process of transferring the design to the fabric through a heat treatment process after being temporarily printed on the film. The cleaning unit 1200 is responsible for the maintenance and management of the print head to prevent the ink nozzle from clogging and to maintain the printing quality through regular cleaning and maintenance. The support unit 1300 supports the printing equipment to improve the printing precision and prevent the material from moving or deforming at will. Among them, the cleaning unit 1200 is the core element to continuously ensure the performance of this system.

[0078] Cleaning department work process

[0079] Figure 2a to Figure 2c 1 is a front view showing the cleaning unit 1200 of the printer device 1000 according to the present invention. Figure 2a to Figure 2c 1 and 2 are diagrams sequentially showing the operation process of the cleaning unit 1200 of the printing device 1000 .

[0080] Figure 2a The print head module 100 and the vacuum capture station module 200 are shown. The main structural element of the print head module 100 is the print head 110. After the printing operation is completed, in order to maintain the printing quality, it is necessary to remove the ink residue remaining in the print head 110. In this process, the vacuum capture station module 200 plays an important role.

[0081] The vacuum capture station module 200 includes a vacuum capture part 210, a vacuum pump 220 and a vacuum capture housing 230. The vacuum capture part 210 is used to suck the ink remaining in the print head 110, and for this purpose, the vacuum capture part 210 is connected to the vacuum pump 220. The distance between the print head 110 and the vacuum capture part 210 is adjusted by the vacuum capture housing 230.

[0082] The height of the vacuum collection housing 230 can be adjusted, and the vacuum collection unit 210 is moved to a position close to the print head in order to absorb the ink of the print head 110. Thus, the vacuum collection unit 210 is closely attached to the print head 110 and the ink is effectively absorbed.

[0083] In order to optimize the efficiency of ink absorption, the vacuum pump 220 is activated after the print head 110 contacts the vacuum trap 210. However, when discharging ink, the vacuum pump 220 may be operated when the print head 110 is not in contact with the vacuum trap 210. The vacuum pump 220 operates when the vacuum trap 210 is in close contact with the print head 110, thereby effectively removing the residual ink 250 of the print head 110.

[0084] according to Figure 2b Even after the ink is captured from the print head 110, a portion of the ink will remain in the print head in the form of bubbles. This is because there are limitations to completely removing the ink by vacuum suction.

[0085] When the vacuum collecting housing 230 is lowered, the ink remaining in the print head 110 requires an additional cleaning process. To this end, a blade cleaning module 300 is introduced, which includes a cleaning blade 310.

[0086] according to Figure 2c In the blade cleaning module 300, the cleaning blade 310 is rotated and raised to match the height of the print head. Afterwards, the print head 110 passes the position where the cleaning blade 310 is located and naturally performs the following process, that is, the cleaning blade wipes the print head and physically removes the ink remaining on the surface of the print head.

[0087] In this case, the blade cleaning module 300 operates independently of the vacuum capture station module 200. The vacuum capture station module 200 ends contact with the print head 110 by descending, but the blade cleaning module 300 does not ascend or descend, but contacts the print head by rotating the cleaning blade 310.

[0088] After that, the ink remaining in the print head is removed by physical contact. Figure 2c The ink removal process described in will be described in detail later.

[0089] Working process of the blade cleaning module

[0090] Figure 3a and Figure 3b To show Figure 1 A perspective view of a blade cleaning module 300 of an embodiment of the present invention. Figure 4a and Figure 4b For viewing from the left Figure 3a and Figure 3b A three-dimensional view of the blade cleaning module 300.

[0091] Figure 3a and Figure 4a The cleaning blade 310 is immersed in the cleaning liquid storage portion 330. Figure 3b and Figure 4b This is a diagram showing a state where the cleaning blade 310 is rotated and raised for cleaning.

[0092] First, each structural element is described, and then its operation is described.

[0093] Reference Figure 3a , Figure 3b , Figure 4a and Figure 4b The purpose of the present invention is to reduce the complicated operations of the user by automating the cleaning process of the nozzle of the print head 110, effectively remove the ink and protect the nozzle. The main structural elements and functions are as follows.

[0094] The blade cleaning module 300 mainly functions to remove ink from the nozzle surface of the print head. The cleaning blade 310 is designed to be able to contact the nozzle surface of the print head and perform a cleaning process through a rising and falling function based on rotation.

[0095] The blade rotation control unit 320 adjusts the rotation of the blade to raise the cleaning blade 310 or to immerse the cleaning blade 310 in a cleaning liquid in a cleaning liquid storage unit 330 to be described later.

[0096] The cleaning liquid storage unit 330 stores the cleaning liquid used in the cleaning process, so that the cleaning blade 310 that has completed cleaning is soaked and cleaned by the cleaning liquid. The cleaning liquid supply units 340A and 340B supply the cleaning liquid to the blade as needed. The cleaning liquid discharge units 350A and 350B discharge the used cleaning liquid. The supply of the cleaning liquid and the discharge of the used cleaning liquid are sequentially performed according to the cleaning procedure.

[0097] The blade rotation recognition unit 360 detects the rotation state of the blade and can perform precise control through the sensor indicator 361 and the rotation recognition sensor 362. Specifically, the sensor indicator 361 rotates along with the rotation of the cleaning blade 310, and when the sensor indicator 361 rotates, the rotation recognition sensor 362 can generate a rotation end signal by detecting at the rotation end position.

[0098] The blade rotation control unit 320 participates in the rise and fall of the blade. The blade rotation control unit 320 can be implemented as a stepper motor. When the blade cleaning process is required, the stepper motor will work, and the cleaning blade 310 will rotate in the clockwise direction. When the sensor indicator 361 reaches the detection area of ​​the rotation identification sensor 362, the stepper motor will stop working. In this case, the cleaning blade 310 is located at an optimal height to wipe the nozzle surface of the print head 110 in an upright state.

[0099] The blade rotation recognition unit 360 may be controlled by the blade rotation control unit 320 in a logical manner, in addition to a physical indicator sensor, and may be implemented in various configurations according to circumstances.

[0100] The X-axis position adjustment gauge 370 and the Y-axis position adjustment gauge 380 adjust the exact position of the blade. The X-axis position adjustment gauge 370 adjusts the cleaning blade 310 in the X-axis direction, and the Y-axis position adjustment gauge 380 adjusts the cleaning blade 310 in the Y-axis direction. It has a portion that can be adjusted along the X-axis and Y-axis directions and is fixed by bolts.

[0101] The splash guard 390 prevents cleaning water or the like that may be splashed downward during the cleaning process.

[0102] Figure 5a The figure is a flow chart showing a cleaning process of a printer device according to an embodiment of the present invention. Figure 5b To show Figure 5a A flow chart of the ink absorption process in the cleaning process involved in the embodiment. Figure 5c To show Figure 5a A flow chart of a blade cleaning process in a cleaning process according to an embodiment of the present invention.

[0103] Reference Figure 5a , the normal printing process S100 is performed, and after each unit printing process, a process S200 of checking whether a cleaning condition is required is performed. In this case, when it is determined that cleaning is required, an ink absorption process S300, a blade cleaning process S400 and a flashing process S500 will be performed.

[0104] Reference Figure 5b and Figure 5c , the specific process is explained.

[0105] First, refer to Figure 5b , the print head 110 first moves to a designated cleaning position (step S310). In this case, at least one print head 110 corresponds to at least one vacuum trapping portion 210 at a corresponding position.

[0106] Afterwards, the vacuum capture part 210 will rise (step S320). Based on this, the print head 110 and the vacuum capture part 210 will eventually contact each other (step S330). After contacting each other, the vacuum pump 220 will be driven to capture the ink (step S340). After the capture is completed, the vacuum pump 220 descends to the vacuum capture part 210 (step S350). Then, the next cleaning step is entered.

[0107] Reference Figure 5cThe cleaning blade 310 is raised by the rotation of the blade rotation control unit 320 (step S410 ). The blade cleaning module 300 does not perform a separate rising and falling motion, and the cleaning blade 310 is raised only by the rotation of the blade rotation control unit 320 .

[0108] After ascending, the print head 110 moves to the position of the cleaning blade 310. The print head 110 moves toward the cleaning blade 310 to wipe off the ink attached to the head, and the cleaning blade 310 scrapes off the ink attached to the nozzle surface of the print head 110 (step S420).

[0109] After scraping the ink from the print head 110, the cleaning blade 310 is lowered by a rotational motion. In this case, the cleaning blade 310 is immersed in the cleaning liquid storage portion 330 storing the cleaning liquid, and the cleaning liquid cleans the ink attached to the cleaning blade 310. Through this process, even if the blade is cleaned multiple times, the ink attached to the cleaning blade 310 remains in a state of being cleaned by the cleaning liquid in advance.

[0110] Cleaning the cleaning blade 310 in this manner can prevent the nozzle surface from being damaged, and the user does not need to clean the blade every time.

[0111] Independently from this, the cleaning liquid storage unit 330 is replenished with cleaning liquid and discharged. Purified water can be used as the cleaning liquid. The purified water can dissolve the aqueous ink attached to the cleaning blade 310. First, the cleaning liquid is supplied through the cleaning liquid supply units 340A and 340B (step S440).

[0112] The cleaning blade 310 rotates and moves between the cleaning liquid, during which the cleaning liquid dilutes the ink. The blade of the cleaning blade 310 is immersed in the cleaning liquid added to the cleaning liquid storage part 330, during which the ink is dissolved by the cleaning liquid.

[0113] During this process, the contaminated cleaning liquid stored in the cleaning liquid storage unit 330 is discharged through the cleaning liquid discharge units 350A and 350B (step S450). The cleaning liquid in the cleaning liquid storage unit 330 that is contaminated by ink due to continuous cleaning is discharged to the outside. Thus, the cleaning liquid is maintained at a purity level above the specified level, which can prevent the time for dissolving the ink attached to the cleaning blade 310 from being delayed. The contaminated purified water as the discharged cleaning liquid is discharged to a separate storage.

[0114] Additional Embodiments

[0115] Figures 6a to 6c A vacuum collection station module and a blade cleaning module according to another embodiment of the present invention are shown.

[0116] Reference Figure 6a The vacuum capture station module 200 includes two vacuum capture sections 210 . The number of such vacuum capture sections 210 may correspond to the number of the print heads 110 of the print head module 100 and include a plurality of vacuum capture sections 210 .

[0117] exist Figure 6b In this case, the vacuum capture station module 200 includes five vacuum capture parts 210 in total. Figure 6a The figure shows that the upper part of the vacuum trapping part 210 includes a plate. Figure 6b Similarly, a total of five vacuum trapping parts 210 may include a plurality of vacuum trapping parts 210 corresponding to the number and position of the print heads 110 of the print head module 100. The number of vacuum trapping parts 210 may be varied.

[0118] Re-reference Figure 6a and Figure 6b The length and position of the cleaning blade 310 can be configured to be a length that can contact the print head 110. In the figure, the position and number of the print head 110 can be estimated by the configuration position of the vacuum capture unit 210, and when such a print head 110 passes through the blade cleaning module 300, it can pass through the cleaning blade 310.

[0119] exist Figure 6c In the case of , there are two cleaning blades 310, and the two cleaning blades 310 are respectively arranged corresponding to the positions of the vacuum collection part 210. Similarly, the cleaning blades 310 can be arranged to match the positions of the print heads 110 corresponding to the vacuum collection part 210, and the print heads 110 are cleaned corresponding to each cleaning blade 310.

[0120] Figure 7 It is a cross-sectional view showing a blade cleaning module involved in another embodiment of the utility model.

[0121] Reference Figure 7 The blade cleaning module 300 of this embodiment includes a non-interference shrinking storage chamber 331 so that the cleaning liquid storage portion 330 does not interfere with the rotation of the cleaning blade 310 and reduces the storage capacity of the cleaning liquid.

[0122] The non-interfering reduced storage chamber 331 plays a role in reducing the storage capacity of the cleaning liquid without affecting the movement of the cleaning blade 310. The non-interfering reduced storage chamber 331 plays a role in effectively reducing the amount of waste water of the discharged cleaning liquid.

[0123] On the other hand, the cleaning liquid storage part 330 may include a vortex generating groove 332, which generates a vortex in the cleaning liquid when the cleaning blade 310 rotates to promote the cleaning of the cleaning blade 310. The vortex generating groove 332 utilizes the dynamic vortex generated in the cleaning liquid storage part 330 to maximize the cleaning effect of the cleaning blade 310.

[0124] Specifically, the vortex generating groove 332 of the blade cleaning module 300 can be formed by a plurality of long grooves recessed along the long axis of the cylinder shape. When the cleaning blade 310 rotates and moves in the cleaning liquid storage portion 330, this groove effectively generates eddy currents. In particular, the above-mentioned groove includes a surface close to the cleaning blade 310 and a surface away from the cleaning blade 310, and when the cleaning blade 310 rotates and moves, it promotes the generation of cleaning liquid eddy currents between them. This makes the cleaning process of the cleaning blade 310 more effective. The structure of the groove induces eddy currents by interacting with the flow of the cleaning liquid, so that the cleaning process can be strengthened. This eddy current generating groove 332 is formed with multiple, and the cross section can be various shapes such as circular and triangular. In particular, when the cross section is circular, eddy currents can be formed more naturally.

[0125] As described above, although the embodiments are described by limited drawings, any person skilled in the art can make various technical modifications and variations based on the above contents. For example, even if the techniques described above are performed in a different order from the methods described above, and / or the structural elements such as the systems, structures, devices, circuits, etc. described above are combined or combined in a different form from the methods described above, or are replaced by other structural elements or equivalent technical solutions, appropriate results can be achieved. Therefore, other implementation methods, other embodiments, and contents equivalent to the scope of protection claimed by the utility model also fall within the scope of the claims described later.
