Description

Technical Field

[0001] This utility model relates to the technical field of waterless printing machines, specifically a waterless printing machine equipped with a flexible fabric applicator. Background Technology

[0002] Waterless printing machines are a new type of printing equipment that has emerged in the textile printing and dyeing industry in response to the concept of green development. Their core advantage lies in eliminating the large amounts of water used and subsequent wastewater treatment processes in traditional printing methods. By directly transferring or spraying printing ink onto the surface of textile fabrics to complete the pattern printing, water consumption and pollutant emissions are reduced at the source. This environmentally friendly characteristic has led to its increasingly widespread application in printing on various fabrics such as cotton, linen, and synthetic fibers. It particularly aligns with the current transformation needs of textile enterprises for cleaner production and low-carbon operations, becoming an important piece of equipment driving technological upgrades in the printing and dyeing industry.

[0003] A significant drawback of existing waterless printing machines in actual production is insufficient fabric fixing and positioning accuracy. Most current equipment uses rigid clamps or simple pressure roller structures to fix the printing fabric. These structures are difficult to adapt to textile fabrics of varying thicknesses and elasticities—they easily cause stretching and deformation in thin fabrics, positioning misalignment in elastic fabrics, and fail to achieve a tight fit in thick fabrics. This fit and positioning problem directly leads to quality issues such as misregistration and blurred edges in the printed pattern, increasing the defect rate and requiring additional manpower for fabric calibration. This severely impacts production efficiency and product competitiveness, becoming a key bottleneck restricting the further promotion and application of waterless printing machines.

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.

[0017] Please see Figures 1-3 A waterless printing machine equipped with a flexible fabric applicator includes a machine body 1. Support frame plates 2 are bolted to both sides of the machine body 1. Slide grooves 3 are opened through both sides of the support frame plates 2. A shaft 4 is slidably connected inside the slide grooves 3. A flexible roller 5 is rotatably connected to the outer surface of the shaft 4. The outer surface of the flexible roller 5 rolls in contact with a pressure adjusting component 6. A passive roller 7 and an active roller 8 are rotatably connected to the inner wall of the machine body 1. A fixing plate 9 is fixedly connected to the back of the support frame plate 2. The pressure regulating component 6 includes an arc-shaped bracket 61, with three fine rollers 62 rotatably connected to the inner side of the arc-shaped bracket 61. A pressure sensor 63 is connected to the top surface of the arc-shaped bracket 61 by screws. A first wedge 64 is connected to the top of the pressure sensor 63 by screws. A second wedge 65 is slidably connected to the inclined surface of the first wedge 64. A servo electric cylinder 66 is fixedly connected to one end of the second wedge 65. A vertical guide rod 67 is threadedly connected to the top surface of the arc-shaped bracket 61.

[0018] Specifically, a printing substrate 10 and a printing nozzle 11 are fixedly connected to the top of the machine body 1, and guide frames 12 are bolted to both sides of the machine body 1. Guide rollers 13 are rotatably connected to the inner side of the guide frames 12.

[0019] Specifically, the outer surfaces of the guide roller 13, the passive roller 7, and the active roller 8 contact the fabric 14, and the active roller 8 is connected to the drive components on the machine body 1.

[0020] The advantages are that the printing substrate 10 provides a flat working surface for printing, and the printing nozzle 11 can accurately print patterns on the surface of the fabric 14. The two work together to ensure the basic conditions for printing. The guide frame 12 on both sides of the machine body 1 and the guide roller 13 rotatably connected to the inside can guide and straighten the fabric 14 entering the machine body 1. The passive roller 7 and the active roller 8 work together. Under the drive of the drive component connected to the active roller 8, the fabric 14 can be smoothly transported, so that the fabric continuously and evenly adheres to the printing substrate 10, ensuring that the printing nozzle 11 can complete the printing operation continuously. At the same time, the transmission path formed by each component through contact with the fabric 14 is also achieved.

[0021] Specifically, the telescopic end of the servo electric cylinder 66 is fixedly connected to the second wedge block 65, and the cylinder body end of the servo electric cylinder 66 is bolted to the outer surface of the fixing plate 9.

[0022] Specifically, the fine roller 62 rolls in contact with the outer circumferential surface of the flexible roller shaft 5. The inner core of the flexible roller shaft 5 is made of steel, and the outer layer is made of rubber. Three sets of pressure adjustment components 6 are provided on the outer circumferential surface of the flexible roller shaft 5.

[0023] Specifically, the servo electric cylinder 66 and the pressure sensor 63 are connected to the controller via wires, and the top surface of the support frame plate 2 has a through hole, in which the vertical guide rod 67 slides and contacts.

[0024] The advantages are that the rolling contact between the fine roller 62 inside the arc-shaped bracket 61 and the outer circumferential surface of the flexible roller shaft 5 can not only stably transmit pressure, but also reduce the obstruction to the rotation of the flexible roller shaft 5, ensuring the smoothness of fabric conveying; the pressure sensor 63 can monitor the reaction force of the flexible roller shaft 5 on the arc-shaped bracket 61 in real time, and thus provide feedback on the actual pressure on the fabric 14. The controller drives the servo electric cylinder 66 to extend and retract according to the feedback signal, causing the second wedge 65 to slide along the inclined surface of the first wedge 64. Vertical pressure adjustment is achieved by utilizing the displacement conversion of the wedge structure. At the same time, the vertical guide rod 67 can limit the offset of the arc-shaped bracket 61 during the adjustment process, ensuring the stability of the pressure transmission direction; this design can be used for fabrics of different thicknesses and elasticities (such as thin fabrics). (To prevent the material from being stretched and deformed, and to ensure a tight fit for heavy fabrics) The pressing force is adjusted in real time to maintain appropriate pressure when the flexible roller 5 and the passive roller 7 are aligned. This ensures that the fabric 14 does not shift or wrinkle during the printing process, and also avoids damage to the fabric 14 when the active roller 8 transports the fabric 14 due to excessive compression. This keeps the fabric 14 on the printing substrate 10 under appropriate tension, thus adhering to the printing substrate 10 and ultimately improving the printing positioning accuracy and product quality stability. The core function of the pressure adjustment component 6 is to provide precise, dynamic pressure control that is adaptable to different fabric characteristics for the pressing of the fabric 14 between the flexible roller 5 and the passive roller 7, solving the problem of poor adaptability of traditional rigid pressing structures.

[0025] In use, firstly, one end of the fabric 14 to be printed is passed sequentially through the mating area of ​​the guide roller 13, flexible roller 5, and passive roller 7 inside the guide frame 12, and finally adhered to the outer surface of the active roller 8. The guiding action of the guide roller 13 ensures that the fabric 14 is transported in a regular path, avoiding initial deviation. Then, the drive components and controller on the machine body 1 are started, and the active roller 8 begins to rotate, driving the fabric 14 into the printing area. At the same time, the controller initializes the state of the servo electric cylinder 66, so that the pressure regulating component 6 is in the initial pressure position. The flexible roller 5 maintains basic contact with the fabric 14 with the cooperation of the shaft 4 and the slide 3. The pressure sensor 63 monitors in real time the reaction force transmitted from the flexible roller 5 to the arc-shaped bracket 61 through the thin roller 62, and feeds back the pressure signal of the fabric 14 to the controller. The controller drives the servo electric cylinder 66 to extend and retract according to the thickness and elasticity characteristics of the fabric 14, driving the second wedge 65. Sliding along the inclined surface of the first wedge 64, the wedge displacement drives the arc-shaped support 61 and the fine roller 62 to move up and down. With the limiting effect of the vertical guide rod 67, the pressing force of the flexible roller 5 on the fabric 14 is precisely adjusted to ensure that the fabric 14 is tightly attached to the printing substrate 10 without being pulled or squeezed. When the fabric 14 passes smoothly over the printing substrate 10 under the coordinated transport of the active roller 8 and the passive roller 7, the printing nozzle 11 on the top of the machine body 1 accurately completes the pattern printing on the surface of the fabric 14 based on the flat working surface. Throughout the printing process, the pressure regulating component 6 continuously adjusts the pressure of the flexible roller 5 through closed-loop control via feedback signals from the pressure sensor 63, controller analysis, and drive by the servo electric cylinder 66. The active roller 8 continuously and stably transports the fabric 14 to ensure that the subsequent fabric area is always in a suitable tension state until the entire roll of fabric is printed and the equipment is shut down.
