Description

Technical Field

[0001] This invention relates to the field of fabric printing equipment technology, specifically to a digital printing online high-penetration penetration device. Background Technology

[0002] With the rapid development of the global digital printing industry and the continuous expansion of the market, downstream sectors such as textiles and home decoration are constantly increasing their demands for printing efficiency, quality, and environmental protection. This is driving the upgrade of digital printing technology towards integration and high efficiency, giving rise to digital printing inline penetration equipment. Traditional printing processes mostly use hand-scraping or machine-scraping screen printing, which requires advance plate making and film preparation. The process is cumbersome and cannot meet the market demand for small-batch, fast-response and multi-color customization. In addition, there are environmental and safety hazards such as large amounts of wastewater discharge and chemical pastes that are harmful to human health. Although early digital printing technology simplified the plate making process, it mostly used external equipment to spray treatment liquid, which had problems such as complex processes, serious waste of treatment liquid, and labor-intensive time, making it difficult to achieve large-scale industrial production.

[0003] Existing digital direct-to-garment technology has obvious drawbacks. The ink penetration effect after printing is uneven, which can easily lead to problems such as uneven color yield and unclear patterns. Furthermore, the difference in penetration between different fabrics results in a high defect rate.

[0004] This case arose in order to resolve the aforementioned issues. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides an online high-permeability digital printing printing device, which solves the problems mentioned in the background section.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a digital printing inline high-feed penetration device, comprising a penetration device body, wherein a front traction roller and a rear traction roller are respectively provided on the upper end of the penetration device body, and a piece of fabric is rotatably connected to the two traction rollers; a photoelectric ring forming detector is provided below the front traction roller, and the photoelectric ring forming detector is fixed on an extension column extending outward from the penetration device body; a pressure penetration structure is provided inside the penetration device body, and the pressure penetration structure includes a lower penetration roller and an upper chrome-plated penetration roller.

[0007] Preferably, the lower penetrating roller and the upper penetrating chrome-plating roller are arranged vertically on a straight line. A synchronous transmission belt is rotatably connected to the lower penetrating roller, and the other end of the synchronous transmission belt is rotatably connected to the output end of the drive structure. The upper penetrating chrome-plating roller is connected to the output end of the adjustable cylinder.

[0008] Preferably, an upper slurry-collecting scraper is provided on the outer side of the upper chrome plating roller, and a lower slurry-collecting scraper is provided on the outer side of the lower adhesive roller. The upper and lower slurry-collecting scrapers are arranged in mirror image and their openings are respectively directed towards the end away from the upper chrome plating roller and the lower adhesive roller.

[0009] Preferably, the side of the penetrating lower rubber roller away from the lower slurry scraper is provided with a wet cleaning structure. The wet cleaning structure includes a water spray nozzle and a water storage tank. The water spray nozzle is aligned with the middle position between the penetrating lower rubber roller and the penetrating upper chrome-plated roller.

[0010] Preferably, a plurality of rotating rollers are fixed on the outer wall of the main body of the permeation device, and a rotating roller is located directly below the rear traction roller.

[0011] Preferably, the lower penetrating roller and the upper penetrating chrome-plated roller are the same size, and the fabric passes between the lower penetrating roller and the upper penetrating chrome-plated roller.

[0012] After adopting the above technical solution, the present invention has the following advantages compared with the prior art: The present invention provides a digital printing online high-penetration penetrating device, which prints on the fabric through two identical and synchronous rollers, a lower penetrating roller and an upper penetrating chrome-plated roller. The wet cleaning structure forms a water film on the fabric, while the residual paste on the fabric is scraped away by the paste-collecting scraper, thereby greatly improving the printing penetration efficiency of the fabric and ensuring clear printing lines and colors.

[0015] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0016] like Figure 1-2 As shown: A digital printing online high-pressure penetration device includes a penetration device body 1. The upper end of the penetration device body 1 is respectively provided with a front traction roller 7 and a rear traction roller 6. Fabric is rotatably connected to the two traction rollers. A photoelectric ring forming detector 8 is provided below the front traction roller 7. The photoelectric ring forming detector 8 is fixed on an extension column extending outward from the penetration device body 1. The penetration device body 1 is provided with a pressure penetration structure, which includes a lower penetration roller 4 and an upper penetration chrome-plated roller 5.

[0017] The working principle of this device is as follows: The fabric moves from the reciprocating fabric feeder 11 to the main body 1 of the penetrating device. A photoelectric ring-forming detector 8 is installed at the fabric inlet of the main body 1 to monitor the fabric 1, thereby ensuring the reserved amount of fabric and achieving continuous and uniform penetrating in the future. The fabric entering the main body 1 of the penetrating device has been uniformly sized in the previous process, so there is sizing material on the fabric at this time. At this time, the upper sizing scraper 9 and the lower sizing scraper 10 can further spread the sizing material on the fabric evenly. Then the fabric passes between the penetrating lower rubber roller 4 and the penetrating upper chrome-plated roller 5 to print the fabric. Then the fabric moves through the rear traction roller 6. During this process, the wet cleaning structure wets the fabric and forms a water film on the fabric. Then the fabric moves further through the photoelectric ring-forming detector 8.

[0018] The penetrating lower rubber roller 4 and the penetrating upper chrome-plated roller 5 are arranged vertically in a straight line. The penetrating lower rubber roller 4 is rotatably connected to a synchronous transmission belt 2, and the other end of the synchronous transmission belt 2 is rotatably connected to the output end of the drive structure. The penetrating upper chrome-plated roller 5 is connected to the output end of an adjustable cylinder. The penetrating lower rubber roller 4 and the penetrating upper chrome-plated roller 5 are kept in absolute synchronization to prevent changes in the pattern color and printing deviations. The penetrating upper chrome-plated roller 5 is in direct contact with the patterned surface of the fabric. Therefore, the penetrating upper chrome-plated roller 5 is a smooth roller to further improve the printing accuracy.

[0019] An upper sizing scraper 9 is provided on the outer side of the upper chrome-plated roller 5, and a lower sizing scraper 10 is provided on the outer side of the lower sizing roller 4. The upper sizing scraper 9 and the lower sizing scraper 10 are arranged in a mirror image and their openings face away from the end of the upper chrome-plated roller 5 and the lower sizing roller 4, respectively. This ensures that the sizing material is the medium and can be evenly applied to the fabric, thereby preventing the fiber surface from spreading directly due to insufficient sizing material, resulting in unclear or blurred lines and the formation of a third color.

[0020] A wet cleaning structure is provided on the side of the penetrating lower roller 4 away from the lower sizing scraper 10. The wet cleaning structure includes a water spray nozzle and a water storage tank. The water spray nozzle is aligned with the middle position between the penetrating lower roller 4 and the penetrating upper chrome-plated roller 5. The upper and lower scrapers ensure that the ink is evenly coated. With the help of the wet cleaning structure 3, a water film is formed on the fabric after it is wetted. Utilizing the principle that the pigment will transfer to the direction of moisture, the entire layer of fabric is penetrated by the pigment, resulting in clear printing. At the same time, the back of the fabric also carries some water molecules after being wetted. This part also has tension, which further assists in the penetration. This solves the problem of uneven ink penetration after digital direct-to-garment printing, while consuming less water and being more environmentally friendly.

[0021] Multiple rotating rollers are fixed on the outer wall of the main body 1 of the permeation device. A rotating roller is located directly below the rear traction roller 6. The lower permeation roller 4 and the upper permeation chrome-plated roller 5 are the same size. The fabric passes through the middle of the lower permeation roller 4 and the upper permeation chrome-plated roller 5. The permeation process is controllable and linear.

[0022] The above-described embodiments are provided for illustrative purposes. Based on the above description, those skilled in the art can make various changes and modifications without departing from the inventive concept. The technical scope of this utility model is not limited to the contents of the specification; its protection scope must be determined according to the claims.
