Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of fabric printing and dyeing, in particular to a fabric printing and dyeing device based on digital technology and a method thereof. BACKGROUND

[0002] The fabric printing and dyeing device based on digital technology is to use various measurement technologies and automatic control methods to print and dye the fabric, and the printing and dyeing efficiency is high. The traditional printing and dyeing device is to directly put the fabric into the dye frame for dyeing, which can completely dye the fabric, but cannot intermittently dye the fabric and cannot realize both complete dyeing and intermittent dyeing.

[0003] The existing fabric printing and dyeing device has the following defects:

[0004] 1. Patent document KR2020130005193U discloses a rotating and vibrating multi-container dyeing device. The dyeing device in this patent makes the fabric fully contact with the dye through vibration and rotation for dyeing. However, this equipment can only realize complete dyeing of the fabric and cannot realize intermittent dyeing of the fabric when intermittent dyeing of the fabric is required. Therefore, a fabric printing and dyeing device based on digital technology that can completely dye the fabric and can intermittently dye the fabric is needed to solve this problem.

[0005] 2. Patent document JP3194565U discloses a fabric dyeing machine provided with a roller conveying device. The dyeing machine in this patent allows to reduce the use of water and improves the dyeing efficiency. It provides a fabric dyeing machine provided with a roller conveying device. This equipment does not have a heating chamber that can adjust the inlet height. When the height of the fabric entering the heating chamber is different, the fabric is easy to contact the shell of the heating chamber, causing the fabric to be contaminated or the heating chamber to be contaminated. Therefore, a fabric printing and dyeing device based on digital technology that can adjust the inlet height of the heating chamber is needed to solve this problem.

[0006] 3. Patent document JP2015535609A discloses an automatic dyeing and dyeing equipment of biopolymer. The dyeing equipment in this patent is used in the field of rapidly accelerating charged biopolymer dyes by biopolymer conjugation, rapidly separates the conjugation of biopolymer with non-dye and dye to shorten the overall dyeing time and save cost, and is easy to operate. Dyeing, bleaching and other operations can be automatically completed by the equipment. The dye solution in the container needs to be manually added after the liquid level height is reduced, and cannot be automatically added to ensure that the liquid level is at a certain height. Therefore, a fabric printing and dyeing device based on digital technology that can automatically measure and add dye solution is needed to solve this problem.

[0007] 4. Patent document CN218812625U discloses a fabric dyeing box with an auxiliary winding function. The dyeing device in this patent solves the problem that existing fabric dyeing boxes are not convenient for controlling the fabric, which leads to easy deviation during winding. In this device, the fabric is placed inside the box by the pressure roller during the movement of the fabric. There is no structure to increase the friction force applied to the fabric, and the tension is insufficient, so the fabric is easy to loosen. Therefore, a fabric dyeing device based on digital technology that can apply friction force to the fabric and increase the stability of the fabric during movement is needed to solve this problem.

The frame box 41 can provide an installation position for the third rotating rod 42, and the third rotating rod 42 can provide support for the friction plate 45, thereby reducing the friction force when the friction plate 45 moves. The tension sensor unit 43 can measure the tension of the second spring 44, and the second spring 44 can transmit the friction force of the friction plate 45 to the tension sensor unit 43. The friction plate 45 can generate friction force with the moving fabric.

[0063] The printing and dyeing method of the fabric printing and dyeing device based on digital technology is as follows:

[0064] S1, by wrapping the fabric around the unwinding shaft 35 outside, then making the fabric pass between the pressing plate 40 and the friction plate 45, driving the pressing plate 40 to move down by the third hydraulic cylinder unit 37 to extrude the fabric, increasing the friction between the friction plate 45 and the fabric, when the fabric moves, the tension sensor unit 43 measures the friction between the fabric and the friction plate 45, then the tension sensor unit 43 transmits the friction information to the computer unit 28, the computer unit 28 controls the third hydraulic cylinder unit 37 to drive the pressing plate 40 to move up and down according to the friction information, so that the friction between the fabric and the friction plate 45 is in a suitable state;

[0065] S2, then make the fabric pass from below the rotating pressure rod 22, the first hydraulic cylinder unit 20 drives the rotating pressure rod 22 to move up and down reciprocatingly, so that the fabric reciprocatingly enters or leaves the dye inside the dye frame 1, thereby realizing intermittent dyeing of the fabric;

[0066] S3, and make the fabric enter the inside of the drying chamber 11 from the second inlet 32 and the first inlet 14, the heating rod unit 48 heats the inside of the drying chamber 11, so that the fabric is heated, the second motor unit 16 drives the fan blade 18 to rotate, so that the air in the inside of the drying chamber 11 flows quickly, thereby the dye on the fabric can be dried faster;

[0067] S4, then the fabric moves out of the drying chamber 11 from the inside of the first rotating rod 13, then the first motor unit 9 drives the winding shaft 10 to wind the fabric;

[0068] S5, during the fabric dyeing process, the liquid level sensor unit 2 measures the liquid level height of the dye inside the dye frame 1, then the computer unit 28 controls the dye pump 4 to pump the dye inside the dye storage cabinet 3 to the inside of the dye frame 1 according to the liquid level height, until the liquid level height of the dye inside the dye frame 1 reaches the set value, thereby ensuring that the dye inside the dye frame 1 is at a suitable height.

[0070] S21, when the fabric drives the rotating pressure rod 22 to rotate, the angle sensor unit 25 measures the rotation angle of the rotating pressure rod 22, and then transmits the rotation angle information to the computer unit 28. The computer unit 28 judges the moving distance of the fabric according to the angle rotation information, so as to facilitate the computer unit 28 to control the work of the first hydraulic cylinder unit 20 according to the dyeing length of the fabric, so that the first hydraulic cylinder unit 20 can drive the rotating pressure rod 22 to move up and down according to the dyeing distance of the fabric, thereby realizing the intermittent dyeing of the fabric;

[0071] S22, when the first hydraulic cylinder unit 20 drives the rotating pressure rod 22 to continuously press the fabric into the inside of the dye, the complete dyeing of the fabric can be realized;

[0072] In S3, the following steps are also included:

[0073] S31, when the fabric enters the first inlet 14 from the second inlet 32, the laser range finder unit 33 measures the height of the fabric. If the position of the fabric is at the low position when moving downward to dye, the laser range finder unit 33 transmits the measurement result to the computer unit 28, and the computer unit 28 controls the second hydraulic cylinder unit 30 to drive the second inlet 32 on the first lifting plate 31 to move downward, so as to avoid the fabric from contacting the first lifting plate 31, and the opening of the second inlet 32 is small, the temperature loss speed in the drying chamber 11 is slower, and the electric energy is saved.

[0074] Working principle: before using the fabric printing and dyeing device based on digital technology, it is necessary to check whether the fabric printing and dyeing device based on digital technology has any problems that affect the use. First, the fabric is wound around the outside of the unwinding shaft 35, then the fabric passes between the pressing plate 40 and the friction plate 45, and the third hydraulic cylinder unit 37 drives the pressing plate 40 to move down to press the fabric, increasing the friction between the friction plate 45 and the fabric. When the fabric moves, the tension sensor unit 43 measures the friction between the fabric and the friction plate 45, and then the tension sensor unit 43 transmits the friction information to the computer unit 28. The computer unit 28 controls the third hydraulic cylinder unit 37 to drive the pressing plate 40 to move up and down according to the friction information, so that the friction between the fabric and the friction plate 45 is in a suitable state. Then the fabric passes from below the rotating pressure rod 22, the first hydraulic cylinder unit 20 drives the rotating pressure rod 22 to move up and down reciprocally, so that the fabric reciprocally enters or leaves the dye inside the dye frame 1, thereby realizing intermittent dyeing of the fabric. The fabric enters the drying chamber 11 from the second inlet 32 and the first inlet 14, the heating rod unit 48 heats the inside of the drying chamber 11, so that the fabric is heated, and the second motor unit 16 drives the fan blade 18 to rotate, so that the air in the drying chamber 11 flows quickly, thereby making the dye on the fabric dry faster. Then the fabric moves out of the drying chamber 11 from the inside of the first rotating rod 13, and then the first motor unit 9 drives the winding shaft 10 to wind the fabric. During the dyeing process of the fabric, the liquid level sensor unit 2 measures the liquid level of the dye inside the dye frame 1, and then the computer unit 28 controls the dye pump 4 to pump the dye inside the dye storage cabinet 3 to the inside of the dye frame 1 according to the liquid level, until the liquid level of the dye inside the dye frame 1 reaches the set value, thereby ensuring that the dye inside the dye frame 1 is at the appropriate height. When the fabric drives the rotating pressure rod 22 to rotate, the angle sensor unit 25 measures the rotation angle of the rotating pressure rod 22, and then transmits the rotation angle information to the computer unit 28. The computer unit 28 judges the moving distance of the fabric according to the angle rotation information, so as to facilitate the computer unit 28 to control the work of the first hydraulic cylinder unit 20 according to the dyeing length of the fabric, so that the first hydraulic cylinder unit 20 can drive the rotating pressure rod 22 to move up and down according to the dyeing distance of the fabric, thereby realizing intermittent dyeing of the fabric. When the first hydraulic cylinder unit 20 drives the rotating pressure rod 22 to press the fabric into the dye without interruption, the fabric can be completely dyed. When the fabric enters the first inlet 14 from the second inlet 32, the laser range finder unit 33 measures the height of the fabric. If the position of the fabric is low during the downward dyeing, the laser range finder unit 33 transmits the measurement result to the computer unit 28, and the computer unit 28 controls the second hydraulic cylinder unit 30 to drive the second inlet 32 on the first lifting plate 31 to move downward, thereby avoiding the fabric from contacting the first lifting plate 31, and the opening of the second inlet 32 is small, the temperature loss speed in the drying chamber 11 is slower, thereby saving electric energy.
