Ink-jet digital printing pretreatment production line

Abstract

The utility model discloses an ink-jet digital printing pretreatment production line which is provided with a conveying belt assembly, a pretreatment liquid digital spraying machine, a white ink digital spraying machine and a color ink digital spraying machine. The pretreatment liquid digital spraying machine firstly sprays and prints pretreatment liquid into the textile fabric to form a reaction layer, then the white ink digital spraying machine sprays and prints white bottom layer patterns on the reaction layer, and finally the color ink digital spraying machine sprays and prints color pigments on the white bottom layer patterns to color the white bottom layer patterns. After a pretreatment liquid digital spraying machine sprays a pretreatment liquid to form a reaction layer, and when a white ink digital spraying machine sprays a white bottom layer pattern onto the pretreatment liquid, a white pigment can rapidly react with the pretreatment liquid, so that the white bottom layer pattern completely emerges on the surface of the textile fabric to form a coloring layer, and the white pigment is prevented from permeating into the textile fabric; therefore, the color pigment can be sprayed and printed on the white bottom layer pattern for coloring, and the display effect is better.

Description

Technical Field

[0001] The utility model belongs to the technical field of clothing manufacturing, and in particular relates to an inkjet digital printing pretreatment production line. Background Art

[0002] With the improvement of living standards, consumers' demands for textile fabrics tend to be diversified, personalized and comfortable, and patterns need to be printed on textile fabrics. The existing printing process includes: plate making - film drying - screen drying - scraping printing, which is cumbersome and has low processing efficiency. In addition, when the pattern needs to be printed on dark textile fabrics, the pigment easily penetrates into the textile fabric, resulting in low saturation and contrast of the printed pattern, the whole pattern is not three-dimensional enough, and the printing effect is not good. In addition, the above printing method cannot accurately control the output of the pigment. When the pattern needs to be changed, the plate needs to be re-made, which is difficult to flexibly achieve. Figure 1 print. Utility Model Content

It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the utility model. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the utility model.

[0020] The utility model provides an inkjet digital printing pretreatment production line, comprising: a conveyor belt assembly 1 having a plurality of textile fabrics for laying and capable of driving the textile fabrics to move backward one by one, a pretreatment liquid digital spraying machine 2 arranged at one side of the conveyor belt assembly 1 and capable of spraying a pretreatment liquid to a predetermined position of the textile fabric to form a reaction layer when the textile fabric moves below the conveyor belt assembly 1, and a pretreatment liquid digital spraying machine 2 arranged at one side of the conveyor belt assembly 1 and located behind the pretreatment liquid digital spraying machine 2 and capable of spraying a pretreatment liquid on the reaction layer of the textile fabric when the textile fabric moves below the conveyor belt assembly 1 after the pretreatment liquid printing is completed. A white ink digital sprayer 3 for a white base pattern, a color ink digital sprayer 4 which is arranged on one side of the transmission belt assembly 1 and located behind the white ink digital sprayer 3 and is capable of printing color pigments on the white base pattern of the textile fabric when the textile fabric that has completed the printing of the white base pattern moves underneath it, and a control device which is electrically connected to the transmission belt assembly 1, the pretreatment liquid digital sprayer 2, the white ink digital sprayer 3 and the color ink digital sprayer 4 and is used to control the operation of the transmission belt assembly 1, the pretreatment liquid digital sprayer 2, the white ink digital sprayer 3 and the color ink digital sprayer 4.

[0021] Specifically, the transmission belt assembly 1 is an annular structure, including: a transmission chain arranged in an annular structure and workstations 101 arranged at equal intervals on the transmission chain, each workstation 101 is equipped with a support panel for the textile fabric to be sleeved, and a driving device connected to the transmission chain, which can be a motor.

[0022] Specifically, the pretreatment liquid digital sprayer 2, the white ink digital sprayer 3 and the color ink digital sprayer 4 have the same structure, and all include: a digital sprayer body and a nozzle arranged on the digital sprayer body for printing pretreatment liquid, white base pattern or color pigment onto textile fabrics. Since digital sprayers are common equipment on the market, they will not be described in detail here.

[0023] Specifically, when printing a pattern, the conveyor belt assembly 1 drives the workstation 101 and the textile fabric on the workstation 101 to move backward. When the textile fabric moves to the position of the pretreatment liquid digital sprayer 2, the pretreatment liquid digital sprayer 2 first sprays the pretreatment liquid to a predetermined position of the textile fabric to form a reaction layer. After completion, the conveyor belt assembly 1 continues to drive the textile fabric to move backward. When it moves to the position of the white ink digital sprayer 3, the white ink digital sprayer 3 sprays a white underlying pattern on the reaction layer. After completion, the conveyor belt assembly 1 continues to drive the textile fabric to move backward. When it moves to the position of the color ink digital sprayer 4, the color ink digital sprayer 4 sprays color pigments on the white underlying pattern to color the white underlying pattern.

[0024] Specifically, the composition of the pretreatment solution can refer to Figure 3 When the pigment of the white base pattern comes into contact with the pretreatment liquid, it can react quickly, making the white base pattern emerge on the surface of the dark textile fabric to form a coloring layer. In this way, the color pigment can be sprayed onto the white base pattern for coloring. Against the background of the white base pattern, the saturation of the color pigment is higher, the contrast of the entire pattern is higher, the pattern is more three-dimensional, and the display effect is better.

[0025] Preferably, the present application provides a scraping component 5 before the pre-treatment liquid digital sprayer 2, which can scrape and flatten the textile fabric inserted into the support panel of the station 101, which is beneficial to subsequent processing.

[0026] Specifically, the scraping assembly 5 includes: a support arm and a scraper arranged on the support arm. The scraper and the support arm are slidably matched through a guide rail. The scraper is connected to a transmission belt drive. Driven by the transmission belt, the scraper can slide back and forth along the support arm to scrape the textile fabric below.

A sensing device is arranged on one side of the conveyor belt assembly 1, and the sensing device is located before the pretreatment liquid digital sprayer 2. The sensing device is specifically an RFID reader / writer, and the RFID reader / writer is communicatively connected with the RFID sensing tag and the control device. When the workstation 101 drives the textile fabric and the RFID sensing tag to move to the sensing area of ​​the RFID reader / writer, the RFID reader / writer senses the information stored in the RFID sensing tag and sends the information to the control device. After receiving the information, the pretreatment liquid digital sprayer 2 moves to the position specified by the information and prints the pretreatment liquid onto the textile fabric. The white ink digital sprayer 3 selects the corresponding white underlying pattern and prints it on the textile fabric. The color ink digital sprayer 4 selects the corresponding coloring pigment to color the white underlying pattern.
