Description

Technical Field

[0001] This utility model relates to the technical field of printing stirring ink cartridge devices, and in particular to a home-use DTF printing stirring ink cartridge device based on magnetic attraction. Background Technology

[0002] With the rapid development of digital printing technology, Direct Transfer Film (DTF) printing is gradually gaining popularity in the home market. Home DTF printers are favored by many home users and small studios due to their ease of operation and ability to create personalized designs. However, the inks used in DTF printing are typically water-based / mild solvent systems, containing high concentrations of pigments, hot melt binders, and OEKO-TEX certified additives. These special components make the ink prone to pigment particle sedimentation after standing, severely affecting print quality and results. Therefore, developing a DTF printing ink cartridge stirring device suitable for home environments is crucial for ensuring print quality and promoting the development of DTF printing in the home market.

[0003] Currently, in the field of DTF printing ink mixing, existing technologies mostly employ traditional mechanical structures and principles. For example, mechanical rotary blade mixing systems use a motor to directly drive the mixing blades to rotate within the ink cartridge, relying on the mechanical force of the blades to agitate the ink; vortex centrifugal mixers utilize centrifugal force to create vortices in the ink, achieving mixing; ultrasonic dispersion technology uses high-frequency ultrasonic vibrations to break up aggregated pigment particles; and magnetic levitation mixing systems use magnetic force to suspend the mixing components in the ink for agitation. These technologies all have certain effectiveness in ink mixing and have been widely used in industrial applications.

[0004] However, existing technologies for home DTF printing stirred ink cartridge devices suffer from complexity and maintenance difficulties. Because these technologies are primarily designed for large-scale, continuous industrial operations, their high degree of integration results in complex control circuits and mechanical structures. This not only increases equipment costs but also makes operation more difficult, failing to meet the ease-of-use requirements of home environments. Furthermore, the integrated design of the stirring mechanism and ink bottle makes it difficult for users to disassemble and maintain the bottle separately when the ink is depleted or needs cleaning. The cleaning process is cumbersome and prone to ink leakage, further increasing usage costs and maintenance difficulty, significantly limiting the promotion and use of home DTF printing devices. Therefore, this paper proposes a magnetically-engaged home DTF printing stirred ink cartridge device to address these issues. Utility Model Content

[0029] 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.

[0030] Reference Figures 1-5This utility model provides an embodiment of a magnetically attached home DTF printer stirring cartridge device, including a stirring device inner shell 1, which forms the main frame of the entire device. Made of high-strength, corrosion-resistant engineering plastic, it possesses excellent impact resistance and chemical stability, effectively protecting internal precision components. An upper stirring device shell 8 is fixedly connected inside the inner shell 1, and is secured to the inner shell 1 with screws. The upper shell 8 has a sliding groove structure at its top that adapts to the square opening 2 of the ink bottle, allowing the square opening 2 to slide within it. This sliding connection facilitates the installation and removal of the ink bottle, making it convenient for users to replace ink bottles of different capacities or colors. The square opening 2 of the ink bottle is slidably connected inside the upper shell 8, stirring... Inside the inner shell 1 of the mixing device, a bottom shell 10 of the mixing device is fixedly connected. A battery mounting box 11 is fixedly connected to the outer wall of the bottom shell 10. The battery mounting box 11 consists of a box body and a cover. The box body has a slot for installing lithium batteries to power the device. The cover is tightly connected to the box body via clips, providing dust and moisture protection and ensuring stable battery operation. A mixing main control board 9 is fixedly connected to the bottom of the inner shell 1. The mixing main control board 9 integrates control circuits and sensor circuits, and consists of a microcontroller, power management chip, and signal processing chip. It is used to control the operation of the mixing motor 13 and monitor parameters such as battery power and ink status. An ink bottle sealing cap 3 is slidably connected to the outer wall of the ink bottle square opening 2. The cap 3 is made of silicone, which has good elasticity and sealing properties. Its inner wall has a sealing ring structure that, when fitted with the ink bottle's square opening 2, forms a sealed space to prevent ink leakage or evaporation. An ink bottle filling port plug 4, also made of silicone, is fixedly connected to the outer wall of the cap 3. This plug seals the filling port and can be easily removed when adding ink. After adding ink, it can be tightened again to ensure the ink bottle's seal. An ink agitator 5, made of corrosion-resistant stainless steel, is cylindrical with spiral blades. Placed inside the ink bottle, it rotates and agitates the ink under a magnetic field, redispersing precipitated pigment particles and preventing print quality degradation due to ink sedimentation. The ink bottle's square opening 2 contains an ink bottle outlet tube 6. The outer wall of the ink bottle outlet tube 6 is fitted with a check valve 7, which is a spring-loaded one-way valve consisting of a valve body, valve core, and spring. It controls the unidirectional flow of ink, opening when ink is supplied to the printer and automatically closing when printing ends or system pressure changes, preventing ink backflow and ensuring that ink flows only to the printer along a preset path. The outer wall of the check valve 7 is located inside the upper shell 8 of the stirring device. A motor mounting base 12 is fixedly connected to the outer wall of the bottom shell 10 of the stirring device. A stirring motor 13 is fixedly connected inside the motor mounting base 12. A motor stirring rotor 14 is fixedly connected to the output end of the stirring motor 13. A motor stirring magnetic block 15 is installed inside the motor stirring rotor 14, used for internal stirring.

[0031] Specifically, the ink bottle, as the core component for storing and transmitting ink, relies on its sealing and connection structure to ensure ink quality and stable ink supply. The ink bottle sealing cap 3 fits tightly with the ink bottle through the ink bottle square opening 2, ensuring that ink does not leak during stirring, while isolating it from external air to prevent the ink from drying out or deteriorating. It also allows users to easily disassemble and clean the inside of the ink bottle. The ink bottle filling port plug 4 is made of elastic materials such as silicone, allowing for easy insertion and removal. This facilitates ink addition and allows the filling port to be completely sealed when not in use, preventing impurities from entering the ink bottle. The ink bottle outlet tube 6 plays a crucial role in ink transmission. One end passes through the ink bottle sealing cap 3 and extends to the bottom of the ink bottle, with a dovetail anti-clogging opening design at the end. This special structure effectively expands the ink absorption area, reduces ink residue, and lowers the risk of pigment particles clogging the tube. The other end connects to a check valve 7, which has a one-way flow characteristic. It opens when ink is supplied to the printer and automatically closes when printing ends or when the system pressure changes, preventing ink backflow from contaminating the ink bottle or causing printing malfunctions, ensuring that the ink flows only along the preset path. The ink stirring process relies on magnetic drive for efficient operation. The lithium battery built into the battery housing 11 provides stable power to the entire system, allowing it to operate independently of the printer and meet the flexible usage needs of home environments. The stirring control board 9 precisely controls the operation of the stirring motor 13 based on preset programs or real-time detected ink status data. When the motor starts, the stirring rotor 14 drives the stirring magnetic blocks 15 to rotate at high speed. The magnetic blocks are arranged in a specific polarity combination, generating an alternating magnetic field during rotation. This magnetic field passes through the stirring device shell 1 and the ink bottle sealing cap 3, which are made of high-strength, corrosion-resistant materials, and forms a strong magnetic attraction with the ink stirring element 5 inside the ink bottle. The ink stirring element 5 is made of polytetrafluoroethylene (PTFE), which is resistant to ink corrosion, and under the drive of the magnetic field... The high-speed rotation of the motor, with its unique blade shape and angle design, generates a powerful vortex within the ink bottle, rapidly redispersing settled pigment particles and hot melt binders. Within minutes, the ink reaches a uniform mixing state, ensuring high-quality printing. Throughout the workflow, the stirring control board 9 continuously plays an intelligent regulatory role. Through built-in sensors, it monitors ink concentration, sedimentation, and other parameters in real time, comparing the data with preset thresholds. When sedimentation or concentration changes are detected, it automatically adjusts the speed and duration of the stirring motor 13. After prolonged settling, it activates a high-speed stirring mode to quickly break up sediment; during printing, it switches to low-speed intermittent stirring to maintain ink uniformity while reducing energy consumption and noise. Furthermore, the control board also features battery power monitoring and overcharge / over-discharge protection functions, ensuring stable and safe operation of the device and fully meeting the stringent requirements of home DTF printing for ink stirring and supply.

[0032] Working principle: The ink bottle sealing cap 3 is tightly connected to the ink bottle through the ink bottle square opening 2 to achieve a seal. The ink bottle filling port plug 4 is used to seal the ink filling hole for easy ink addition. One end of the ink bottle outlet tube 6 passes through the ink bottle sealing cap 3 and is placed at the bottom of the ink bottle. The end is a dovetail anti-clogging opening, and the other end is connected to the check valve 7, which is connected to the printer ink supply system. During operation, the ink agitator 5 is powered by the built-in lithium battery in the battery installation box 11. The agitator main control board 9 controls the agitator motor 13 to operate. The motor agitator rotor 14 drives the motor agitator magnetic block 15 to rotate at high speed, generating an alternating current. A variable magnetic field is generated, which passes through the inner shell 1 of the stirring device and the ink bottle sealing cap 3, and forms a magnetic attraction with the ink stirrer 5 inside the ink bottle, driving it to rotate synchronously. The rotation of the ink stirrer 5 generates eddies in the ink bottle, which redisperse the precipitated pigment particles, hot melt powder binder, etc., to ensure ink uniformity. During printing, the ink flows to the printer through the ink outlet tube 6 of the ink bottle under the one-way conduction of the check valve 7 to avoid backflow. At the same time, the stirring main control board 9 monitors the ink status in real time and adjusts the speed and stirring time of the stirring motor 13 as needed to achieve efficient and stable ink stirring and ink supply.

[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
