Description

Technical Field

[0001] This utility model relates to the field of inkjet printing printhead technology, specifically to an ink-blocking textile inkjet printing printhead and its self-cleaning structure. Background Technology

[0002] In the field of textile inkjet printing, the inkjet printhead is a core component, and its performance directly determines the accuracy, speed and stability of printing. However, during long-term use, ink residue is easily left on the nozzle and surface. In particular, water-based or dispersible inks commonly used in textile printing are prone to dry and clump after being exposed to air due to moisture evaporation, which can lead to nozzle blockage or problems such as ink splatter and broken lines during printing, seriously affecting printing quality and production efficiency.

[0003] Existing technologies have produced inkjet head bodies with basic anti-clogging functions. These bodies reduce ink retention at the nozzle by optimizing the ink chamber structure, drive unit response speed, or ink flow path. However, in actual use, the printhead surface will inevitably be contaminated with residual ink. If this residual ink is not cleaned in time, it will gradually accumulate and solidify, which will not only increase the risk of clogging but may also contaminate the fabric surface during printing, resulting in an increase in the defect rate. Utility Model Content

[0004] The purpose of this invention is to provide an anti-clogging inkjet printer nozzle for textiles and its self-cleaning structure to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a self-cleaning structure, including an inkjet printer printhead module body, and further comprising:

[0006] Vertical plates are fixedly connected to the four corners of the bottom of the inkjet printer printhead module body. Rotating shafts are movably connected to both sides of the inner side of the vertical plates. Pulleys are fixedly connected to the front and rear sides of the rotating shafts. A transmission belt is sleeved on the surface of the pulleys. The transmission belt is located at the front and rear sides of the bottom of the anti-clogging inkjet head body.

[0007] The cleaning mechanism is located on the bottom left side of the printhead module body of the inkjet printer. The cleaning mechanism includes a movable base, which is fixedly connected to the left side of the top of the transmission belt.

[0008] The replacement mechanism is located inside the movable base and includes a mounting block located at the bottom of the inkjet printer printhead module body.

[0009] Preferably, the cleaning mechanism further includes a motor, which is fixedly connected to the left side of the bottom of the inkjet printer printhead module body. A large wheel is fixedly connected to the output end of the motor, and a belt is fitted on the surface of the large wheel. A small wheel is provided on the left side inside the belt, and the small wheel is fixedly connected to the surface of the rotating shaft. A cleaning wiper is provided inside the movable seat, and the cleaning wiper is located on the left side of the bottom of the anti-clogging printhead body.

[0010] Preferably, the replacement mechanism further includes a slot, which is formed on both sides of the inner wall of the mounting block. A card plate is engaged inside the slot, and the bottom of the card plate is movably connected to the inside of the movable seat. A support plate is fixedly connected to the bottom of the inner wall of the movable seat. Spring pieces are fixedly connected to both sides of the support plate.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] This invention utilizes a motor to drive a rotating shaft, pulley, and transmission belt to rotate, allowing the cleaning wiping plate to move back and forth on the bottom of the anti-clogging inkjet head body for wiping. Once the bottom of the anti-clogging inkjet head body is cleaned, the surface of the cleaning wiping plate becomes dirty. By pushing the push block and push rod, the clamping plate rotates and separates from the clamping slot, causing the mounting block and the cleaning wiping plate to lose their fixation. Finally, the dirty cleaning wiping plate is removed from the top of the moving base and replaced with a new one. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1 - Figure 7 As shown, the self-cleaning structure includes an inkjet printer printhead module body 1, and also includes: vertical plates 3 fixedly connected to the four corners of the bottom of the inkjet printer printhead module body 1, rotating shafts 4 are movably connected to both sides of the inner side of the vertical plates 3, and pulleys 5 are fixedly connected to the front and rear sides of the rotating shafts 4, and a transmission belt 6 is sleeved on the surface of the pulleys 5, and the transmission belt 6 is located on the front and rear sides of the bottom of the anti-clogging inkjet head body 2.

[0027] To ensure the inkjet head body 2 remains clean after use, a cleaning mechanism 7 is provided. Located on the bottom left side of the inkjet printer printhead module body 1, the cleaning mechanism 7 includes a movable base 71, which is fixedly connected to the top left side of the transmission belt 6. The cleaning mechanism 7 also includes a motor 72, which is fixedly connected to the bottom left side of the inkjet printer printhead module body 1. A large wheel 73 is fixedly connected to the output end of the motor 72. A belt 74 is fitted onto the surface of the large wheel 73. A small wheel 75 is located on the left side inside the belt 74 and is fixedly connected to the surface of the rotating shaft 4. A cleaning wiper plate 76 is located inside the movable base 71 on the bottom left side of the inkjet head body 2. Recesses 77 are provided at the four corners of the inner wall of the movable base 71, and protrusions 78 are provided inside the recesses 77. These protrusions 78 are fixedly connected to the four corners of the surface of the cleaning wiper plate 76.

[0028] When the surface of the anti-clogging inkjet head body 2 needs to be cleaned, the motor 72 is started. The motor 72 drives the large wheel 73 to rotate, the large wheel 73 drives the belt 74 and the small wheel 75 to rotate, the small wheel 75 drives the rotating shaft 4 to rotate, the rotating shaft 4 drives the pulley 5 to rotate, the pulley 5 drives the transmission belt 6 to rotate, and the transmission belt 6 causes the top moving seat 71 and the cleaning wiping plate 76 to move to the right. When the cleaning wiping plate 76 passes the bottom of the anti-clogging inkjet head body 2, it will wipe away the residual ink at the bottom of the anti-clogging inkjet head body 2. The cleaning wiping plate 76 can move back and forth in the left and right directions through the transmission belt 6, and the cleaning wiping plate 76 can wipe repeatedly.

[0029] Please see Figures 3-6 As shown, a replacement mechanism 8 is disposed inside the movable base 71. The replacement mechanism 8 includes a mounting block 81, which is located at the bottom of the inkjet printer printhead module body 1. The replacement mechanism 8 also includes a slot 82, which is formed on both sides of the inner wall of the mounting block 81. A card plate 83 is engaged inside the slot 82. The bottom of the card plate 83 is movably connected to the inside of the movable base 71. A support plate 84 is fixedly connected to the bottom of the inner wall of the movable base 71. Spring pieces 85 are fixedly connected to both sides of the support plate 84. The side of the spring piece 85 away from the support plate 84 contacts the surface of the card plate 83. A push rod 86 is disposed on the outer side of the card plate 83. A push block 87 is fixedly connected to the outer side of the push rod 86 and is slidably connected to both sides of the movable base 71. A force plate 88 is fixedly connected to the surface of the spring piece 85. The other side of the force plate 88 is fixedly connected to both sides of the support plate 84.

[0030] After prolonged use, the surface of the cleaning wipe plate 76 will become covered with ink. In this case, a clean cleaning wipe plate 76 needs to be replaced. Push the push block 87 to move inward. The push block 87 drives the push rod 86 to move inward. The push rod 86 drives the clamping plate 83 to rotate inward. The clamping plate 83 rotates away from the clamping slot 82. The clamping plate 83 compresses the spring 85. When the clamping slot 82 and the clamping plate 83 separate, the mounting block 81 loses its fixing effect. Move the cleaning wipe plate 76 upward. The mounting block 81 of the cleaning wipe plate 76 exits the interior of the moving base 71. The dirty cleaning wipe plate 76 is now removed. Then, place the new cleaning wipe plate 76 on top of the moving base 71 and release the push block 87 to fix the new cleaning wipe plate 76 on top of the moving base 71.

[0031] This utility model also provides an anti-clogging inkjet printhead for textiles, including an anti-clogging printhead body 2 and a self-cleaning structure. The self-cleaning structure is placed on the anti-clogging printhead body 2. The anti-clogging printhead body 2 is fixedly connected to the bottom of the inner wall of the inkjet printer printhead module body 1. The inkjet printer printhead module body 1 and the anti-clogging printhead body 2 are internally connected.

[0032] The aforementioned anti-clogging inkjet head body 2 is a product with relatively mature existing technology. Its working principle is as follows: The anti-clogging inkjet head body 2 is the core execution component of the inkjet printing equipment, directly responsible for accurately ejecting ink in the form of tiny droplets onto the printing medium (such as paper, textiles, leather, etc.) to form patterns or text. Its structure and performance directly determine printing accuracy, speed, stability, and ink adaptability. Simply put, the core components of the anti-clogging inkjet head body 2 include: Ink chamber / cavity: stores the ink to be ejected and connects to an external ink supply system to ensure a continuous ink supply; Nozzle array: a large number of tiny nozzles (ranging from tens to thousands) distributed on the printhead surface through which ink droplets are ejected. The precision and density of the nozzles affect the printing resolution (e.g., 6). 00dpi, 1200dpi); Drive unit: The key component that controls ink droplet ejection according to electrical signals. Common types include piezoelectric crystals (piezoelectric printheads) or heating resistors (thermal printheads). Bubbles are generated through physical deformation (piezoelectric) or instantaneous heating (thermal printheads), which apply pressure to the ink in the ink chamber, causing the ink droplets to be ejected from the nozzle. The anti-clogging printhead body 2 also includes a circuit layer responsible for signal transmission, as well as sealing and support components to ensure structural stability and prevent ink leakage. Different types of printheads (such as piezoelectric and thermal printheads) differ in their driving principles and structural details, but their core function is to achieve high-quality printing by precisely controlling the size, speed, and position of ink droplets. It should be noted that conventionally available printheads can be used for anti-clogging textile inkjet printing.

[0033] Working principle: The motor 72 drives the rotating shaft 4, pulley 5, and transmission belt 6 to rotate, so that the cleaning wiping plate 76 can move back and forth to wipe the bottom of the anti-clogging inkjet head body 2. The motor 72 can be set to a motor structure with forward and reverse rotation function, and can be connected to an external PLC for control via wires, so as to facilitate control of forward and reverse rotation. When the bottom of the anti-clogging inkjet head body 2 is cleaned, the surface of the cleaning wiping plate 76 is dirty. By pushing the push block 87 and push rod 86, the clamping plate 83 is rotated and separated from the clamping slot 82, so that the mounting block 81 and the cleaning wiping plate 76 are no longer fixed. Finally, the dirty cleaning wiping plate 76 is removed from the top of the moving base 71 and replaced with a new one.
