Description

Technical Field

[0001] This utility model relates to the field of digital printing technology, and in particular to a device for removing short fibers from fabric surfaces using high-pressure blowing and low-pressure suction. Background Technology

[0002] In the actual production process of a fabric mill, due to inherent limitations in textile technology and insufficiently refined carding processes, some broken short fibers inevitably remain on the fabric surface. When the printhead performs ink droplet ejection, the presence of these short fibers becomes an interfering factor, causing the ink droplets to fail to adhere precisely to the fabric surface and instead be printed onto the short fibers, significantly altering the intended attachment position and distribution pattern of the droplets. In the subsequent high-temperature color development stage, the bonding force between the short fibers and the fabric substrate is broken due to heat, causing them to detach from the fabric. This process leaves obvious marks on the fabric surface, severely damaging the image quality, causing numerous flaws in the pattern, and resulting in uneven and inconsistent color distribution, greatly affecting the aesthetics and quality of the finished product. Utility Model Content

[0003] To address the aforementioned issues, this invention proposes a device for removing short, broken fibers from fabric surfaces using high-pressure blowing and low-pressure suction. This device can be integrated into a thermal sublimation digital printing device, becoming part of the equipment, or it can function as an independent external device.

[0004] The technical solution adopted in this utility model is as follows: a device for removing short fibers from a fabric surface using high-pressure blowing and low-pressure suction, comprising a device housing disposed between two support rollers, wherein a set of high-pressure blowing ducts and a set of low-pressure suction ducts are respectively disposed at the top and bottom of the device housing; the low-pressure suction ducts are disposed opposite to each other on the inner wall of the device housing, with a gap between them and the side wall of the device housing; the high-pressure blowing ducts are disposed on the low-pressure suction ducts; the high-pressure blowing ducts have a plurality of high-pressure blowing holes, and the high-pressure blowing holes on the two sets of high-pressure blowing ducts are disposed opposite to each other; low-pressure suction ports are opened on both sides of the low-pressure suction ducts; and fabric inlets and fabric outlets are opened on the side walls of the device housing between the two sets of high-pressure blowing ducts.

[0005] Furthermore, brush sets are provided at the openings of the fabric inlet and the fabric outlet.

[0006] Furthermore, the high-pressure blowing duct and the low-pressure suction duct have the same width.

[0007] The beneficial effects of this invention are as follows: Before the inkjet fabric enters the printing process, it can be passed through the device disclosed in this invention. This device cleverly uses a combination of high-pressure blowing and low-pressure suction to quickly and efficiently remove short fibers remaining on the surface of the inkjet fabric. This measure eliminates many potential problems that may be caused to the printing quality of the fabric due to the presence of short fibers, and effectively avoids problems such as abnormal ink droplet adhesion and uneven distribution. After this treatment, not only can the printed image be ensured to be clear, rich in detail, and have natural, uniform, and coordinated color transitions, but the overall quality of the product can also be significantly improved, bringing users a better visual experience.

Detailed Implementation

[0011] The present invention will be further described below with reference to the accompanying drawings.

[0012] like Figure 1 As shown, this utility model is a device for removing short fibers from a fabric surface using high-pressure blowing and low-pressure suction, comprising a device housing 1 disposed between two support rollers 7. Fabric inlets 15 and fabric outlets 16 are opened on the two side walls 6 of the device housing 1. The printed fabric 8 is supported on the support rollers 7 and passes through the device housing 1 from left to right through the fabric inlet 15 and the fabric outlet 16. The device housing 1 is divided into upper and lower parts with the printed fabric 8 as the symmetrical line. The upper part cleans the short fibers on the front side of the fabric, and the lower part cleans the short fibers on the back side of the fabric.

[0013] The device housing 1 has a set of lower high-pressure air blowing duct 3, lower low-pressure air suction duct 5, upper high-pressure air blowing duct 11, and upper low-pressure air suction duct 12 respectively located at the top and bottom. The lower low-pressure air suction duct 5 and upper low-pressure air suction duct 12 are arranged opposite each other on the inner wall 10 of the device housing 1, with a gap between them and the side wall 6 of the device housing 1. The lower high-pressure air blowing duct 3 and upper high-pressure air blowing duct 11 are arranged on the lower low-pressure air suction duct 5 and upper low-pressure air suction duct 12. The lower high-pressure air blowing duct 3 and upper high-pressure air blowing duct 11 have several lower high-pressure air blowing holes 4 and upper high-pressure air blowing holes 13, which are arranged opposite each other. The lower low-pressure air suction duct 5 and upper low-pressure air suction duct 12 have lower low-pressure air suction ports 2 and upper low-pressure air suction ports 14 on both sides.

[0014] like Figure 2 As shown, in operation, the airflow 17 generated by the high-pressure vortex blower enters from the lower high-pressure blowing duct 3 and the upper high-pressure blowing duct 11, respectively. This airflow 17 then passes through the lower high-pressure blowing hole 4 and the upper high-pressure blowing hole 13. Because the diameter of these holes is extremely small, when the high-pressure airflow 17 passes through, the pressure energy is rapidly converted into high-speed airflow, so that the airflow flowing out of the high-pressure blowing hole carries extremely high kinetic energy.

[0015] When this high-speed airflow is sprayed onto the corresponding areas on both sides of the printing fabric, as long as the impact force generated by the airflow exceeds the bonding force between the broken short fibers and the fabric surface, the broken short fibers can be successfully separated from the fabric substrate. The broken short fibers separated from the fabric surface move to the left and right sides in the direction of fabric movement under the propulsion of the airflow. Since the air volume of the boiler induced draft fan is several times that of the vortex fan, under the strong suction generated by the boiler induced draft fan, the mixed airflow 17 carrying the short fibers will successively enter the lower low-pressure suction port 2 and the upper low-pressure suction port 14, and then enter the upper low-pressure suction duct 12 and the lower low-pressure suction duct 5.

[0016] To effectively prevent airflow mixed with short fibers from flowing out of the fabric inlet 15 or fabric outlet 16 of the device and thus causing air pollution, a set of brushes 9 is installed at the fabric inlet 15 and fabric outlet 16 respectively.

[0017] The mixture of short fibers and air flowing from the lower low-pressure suction duct 5 and the upper low-pressure suction duct 12 first enters the cyclone dust collector for efficient dust removal. During this process, the short fibers in the mixture are separated, and after the treated gas meets the emission standards, it is extracted by the boiler induced draft fan and finally discharged into the atmosphere.

[0018] Although the specific embodiments of the present utility model have been described above in conjunction with the accompanying drawings, this is not intended to limit the scope of protection of the present utility model. Those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art without creative effort based on the technical solution of the present utility model are still within the scope of protection of the present utility model.
