Description

Technical Field

[0001] The present invention relates to the technical field of cloth printing and dyeing, in particular to a multi-stage printing and dyeing type cloth printing and dyeing box. Background Art

[0002] Currently, in the pre-impregnation process of fabrics, existing printing and dyeing equipment lacks effective agitation measures. Some equipment only relies on simple mechanical stirring paddles for stirring operations. However, the water flow formed by such simple stirring paddles cannot form a continuous and stable water flow impact. During the pre-impregnation process, the interaction between water and fabric is difficult to be fully agitated, resulting in the fabric not being able to be uniformly and fully wetted in the pre-impregnation stage, which in turn affects the adsorption effect of dyes on the fabric in the subsequent printing and dyeing process.

[0003] In terms of fabric processing after pre-impregnation, existing printing and dyeing equipment lacks corresponding matching structures for pre-impregnated fabrics. Pre-impregnated fabrics are often in a water-saturated state when entering the subsequent printing and dyeing process. When the fabric enters the printing and dyeing link in this state, the saturated water in the fabric will hinder the adsorption of the dye, resulting in a decrease in the fabric's adsorption rate of the dye. This situation not only causes dye waste, but also makes the printing and dyeing effect unstable, making it difficult to meet the modern textile printing and dyeing industry's demand for high-quality printing and dyeing products.

The bubbles vigorously agitate the water, so that the hot water and the fabric form more sufficient and frequent contact and interaction, further accelerating the pre-impregnation process, improving the pre-impregnation efficiency, saving the pre-impregnation time, and improving the production efficiency of the entire printing and dyeing process.

[0022] Among them, a conveying auxiliary roller 1016 is rotatably installed in the pretreatment chamber 1011 adjacent to the cloth input opening 1025 and the cloth conveying connection opening 1019; two pre-impregnation auxiliary rollers 1017 are rotatably installed in the pretreatment chamber 1011 adjacent to the upper side of the aeration pipe 1022; a conveying auxiliary roller 1016 is also rotatably installed in the printing and dyeing chamber 1012 adjacent to the cloth conveying connection opening 1019 and the cloth output opening 1010; two upper and lower rows of dyeing auxiliary rollers 1018 are rotatably installed at the bottom of the printing and dyeing chamber 1012, and the two rows of dyeing auxiliary rollers 1018 are arranged at intervals. The conveying auxiliary rollers 1016, pre-impregnation auxiliary rollers 1017 and dyeing auxiliary rollers 1018 are all used to assist in the printing and dyeing of the cloth; dye liquid is added to the printing and dyeing chamber 1012, and the dye liquid water level is higher than the dyeing auxiliary rollers 1018.

[0023] The working principle of this embodiment is as follows: The fabric to be printed and dyed enters the pre-treatment chamber 1011 through the fabric input opening 1025. Inside the pre-treatment chamber 1011, the fabric first extends downward along the auxiliary conveying roller 1016 on the left side of the chamber, and is evenly lapped on the bottom of the two pre-impregnation auxiliary rollers 1017. Then, the fabric is lapped upward to the auxiliary conveying roller 1016 on the right side of the pre-treatment chamber 1011. Then, the fabric passes through the gap between the two squeezing rollers 1027 and enters the printing and dyeing chamber 1012 through the fabric conveying connecting opening 1019. After entering the printing and dyeing chamber 1012, the fabric extends downward along the auxiliary conveying roller 1016 on the left side of the chamber, and is lapped on the dyeing auxiliary roller 1018 in an alternating manner from left to right. Finally, the fabric extends upward along the auxiliary conveying roller 1016 on the right side of the printing and dyeing chamber 1012 and is output from the fabric output opening 1010. During fabric printing and dyeing, the airflow generated by the fan connected to the tee pipe 108 is transferred to the upper gas delivery pipe 106 and the lower gas delivery pipe 107 through the tee pipe 108, and is respectively input into the upper gas delivery chamber 1023 and the lower gas delivery chamber 1024, and then ejected from the upper blowing opening 1015 and the lower blowing opening 105, respectively. Due to the inclination angles of the upper notch 1014 and the lower notch 104, the ejected airflow makes oblique contact with the fabric, thereby blowing away impurities attached to the upper and lower surfaces of the fabric, ensuring that no impurities remain on the fabric surface, thereby ensuring the quality of subsequent printing and dyeing. The sprayed fabric is guided by the auxiliary conveying roller 1016 and the pre-impregnation auxiliary roller 1017 and immersed in the water inside the pre-treatment chamber 1011 to achieve pre-impregnation of the fabric, so that the fabric fibers absorb a certain amount of water in advance, thereby opening the gaps between the fiber molecules, making it easier for dye molecules to enter the fibers during subsequent printing and dyeing, thereby improving the dye adsorption rate and dyeing rate. In order to speed up the pre-impregnation efficiency, the water in the pre-treatment chamber 1011 is first heated and maintained at a certain temperature through the cooperation of the electric heating rod 1020 and the temperature sensor 1021. Due to the high temperature of the hot water, the molecular thermal motion is more intense, allowing it to penetrate into the gaps between the fabric fibers more quickly, thereby shortening the time required for fabric soaking and causing the fabric fibers to swell more fully, which is not only conducive to the entry of water molecules into the fibers, but also more conducive to the entry of subsequent dye molecules. Furthermore, based on the aforementioned water heating and maintenance, the airflow generated by the fan connected to the aeration gas delivery pipe 109 is input into the aeration main pipe 1026 through the aeration gas delivery pipe 109, and is transferred to each aeration pipe 1022 via the aeration main pipe 1026, so that the airflow diffuses through the micropores of the aeration pipe 1022, continuously generating fine bubbles in the water. The generation of these bubbles effectively agitates the water, and under the action of the bubbles, the hot water and the fabric form more sufficient and frequent contact and interaction, further accelerating the pre-impregnation process. When the pre-impregnated fabric is conveyed to the squeezing rollers 1027, the fabric passes through the gap between the two squeezing rollers 1027. During this process, the two squeezing rollers 1027 exert a certain squeezing force on the fabric, effectively squeezing out most of the moisture in the fabric. This prevents the fabric from reaching a saturated state due to excessive water absorption, thereby preventing it from adversely affecting the dye adsorption rate when it subsequently enters the printing and dyeing chamber 1012, thereby ensuring the stability and quality of the printing and dyeing effect. When the pre-impregnated fabric begins to be transported into the printing and dyeing chamber 1012, the fabric slowly immerses itself in the dye solution in the printing and dyeing chamber 1012 under the cooperation of the transport auxiliary roller 1016 and the dye dipping auxiliary roller 1018. The dye solution will fully contact and penetrate the fabric fibers, and the fabric will be printed and dyed in a detailed and comprehensive manner. As the fabric is pushed forward, the completely printed and dyed fabric smoothly passes through the fabric output opening 1010 and is output from the printing and dyeing chamber 1012, thus successfully completing the entire fabric printing and dyeing operation process and achieving a coherent processing of the fabric from pre-impregnation to printing and dyeing to output.
