Description

Technical Field

[0001] The present application relates to the technical field of cloth printing, and in particular to a cloth printing device for producing polyester-cotton cloth. Background Art

[0002] Fabric is a commonly used material in decoration, including chemical fiber carpets, non-woven wall cloths, linen, nylon, colored tape, flannel and other fabrics. Fabric plays a considerable role in decorative display and is usually the main force that cannot be ignored in the entire sales space. It can also form a good commercial space display style. When people print on polyester-cotton fabrics, they usually manually place the fabric on a horizontal surface and then manually emboss the fabric with a mold dipped in paint. The manual embossing process is less efficient and the embossing force is difficult to control, resulting in uneven embossing and affecting the appearance.

[0003] After searching, the publication number: CN215512816U discloses a cloth printing device for cloth production, which passes the filler material between two rollers. When the cylinder moves downward to print the cloth, the guide rod drives the rack to move downward, and the one-way gear rotates accordingly, and the rotating shaft does not rotate. When the cylinder is reset, it drives the guide rod to reset, and the one-way gear is driven to rotate through the rack, and the rotating shaft and rollers rotate accordingly. The rotation of the two rollers can flatten and transport the cloth, preventing the cloth from wrinkling when printing, thereby ensuring the printing effect.

[0004] Regarding the above-mentioned related technologies, the inventors believe that there are the following technical defects that need to be improved:

[0005] The printing mold of this device is fixed in position and can only print on fabrics of a specified thickness. The practical effect is average, and the printing mold is not equipped with a related auxiliary scraping structure, which will cause uneven ink distribution and result in the phenomenon of light or heavy printing colors.

[0046] The interior of the printing box 1 is also provided with a cloth guide roller 11, a lifting plate 12, a dustproof box 13 and a hydraulic cylinder 14. The dustproof box 13 is installed on both sides of the printing box 1, and the output end of the hydraulic cylinder 14 is fixedly connected to one side of the lifting plate 12. The surface of the lifting plate 12 is rotatably connected to the cloth guide roller 11. The cloth guide roller 11 is installed below the printing roller 4 and is used to lift the cloth to the embossing position of the printing roller 4.

[0047] The use process of the fabric printing device for polyester-cotton fabric production in the embodiment of the present application is roughly as follows:

[0048] After the cloth is wound on the winding roller 63 at one end away from the curing chamber 3, a corner of the cloth is pulled and passed through the printing box 1 and fixed on the winding roller 63 on the other side. The stepper motor 62 is started to tighten the cloth and complete the cloth winding after printing. In this process, the inkjet body 2 is started in advance to spray ink on the surface of the printing roller 4, and then the push cylinder 51 is started to drive the sliding bracket 52 and the outer scraper 53 on the outside to approach the printing roller 4 and make the tip surface of the outer scraper 53 slightly contact the surface of the printing roller 4. Then, the outer DC motor 9 is started to drive the printing roller 4 to rotate, and the blade surface of the outer scraper 53 is cyclically scraped against the surface of the printing roller 4, thereby The ink thickness on the surface of the printing roller 4 is uniform, improving printing quality. The position of the guide roller 11 can then be adjusted according to the specific thickness of the polyester-cotton fabric. During operation, the hydraulic cylinder 14 inside the dustproof box 13 is activated, and its piston end pushes up the lifting plate 12, thereby raising the guide roller 11. The guide roller 73 supports the fabric and moves it upward until it contacts the surface of the printing roller 4, ensuring the printing effect. Simultaneously, the power cylinder 72 is activated to push the guide rod 73, which pushes the adjustment roller 75 up and down and adjusts its position so that the adjustment roller 75 above the fabric can fully press the fabric, thereby controlling the tension of the fabric during transmission and achieving a tension adjustment effect. Finally, the printed fabric is exposed to ultraviolet light from multiple sets of UV curing lamps 8 within the curing chamber 3. The photosensitizer on the ink surface, stimulated by the ultraviolet light, triggers a chemical reaction, rapidly transforming the material from a liquid or semi-liquid state to a solid state. This process typically takes a few seconds, allowing the printed fabric to dry quickly and avoiding dyeing.

[0049] The beneficial technical effects of the fabric printing device for polyester-cotton fabric production according to the embodiment of the present application are as follows:

[0050] This device uses an external scraper 53 for scraping ink and a printing roller 4 driven by a DC motor 9 to scrape the ink flat on the rotating roller surface, so that the ink thickness on the surface of the printing roller 4 is uniform, thereby preventing the color from being light or heavy when printing on the cloth; on the other hand, this device uses a guide roller 11 and an adjusting roller 75 that can be adjusted up and down to print on cloths of different thicknesses and adjust the surface tension. Finally, the UV curing lamp 8 is used to quickly convert the ink from a semi-liquid state to a solid state, thereby achieving rapid drying of the ink.

[0051] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent replacements and improvements made within the spirit and principles of the application should be included in the scope of protection of the present application.
