[0016] A method for using a green and environmentally friendly inkjet printing device comprises the following steps:

[0017] S1. When the inkjet printing device is used, the unwinding roller with the cloth rolled up is installed at the rotating shaft position during processing, and the winding roller for winding the cloth after printing is installed at the connecting shaft position. At this time, the cloth is pulled out from the unwinding roller position to arrange the cloth winding path. The cloth first passes over the conveyor belt, then passes between the pressure roller and the positioning roller, and then enters from the avoidance groove position on the lower side. The cloth passes through the arc path composed of the guide roller and the sleeve roller, and is sent out in the reverse direction from the upper avoidance groove. At this time, the cloth can be sleeved on the winding roller position to complete the arrangement;

[0018] S2. In the process of winding up, inkjet printing is performed on the surface of the fabric by using the printing head. Starting the first motor can drive the winding roller to rotate to complete the winding of the fabric. When the fabric passes under the printing head, the printing head is used to spray ink from the nozzle to form mist droplets and spray them onto the surface of the fabric, thereby realizing inkjet printing processing on the fabric.

[0019] S3. As the conveyor belt runs, the cloth can be delivered along with the cloth being rolled up. At the same time, the conveyor belt is in a breathable state by setting the micropores on the surface of the conveyor belt. At the same time, the fan is started, and the fan can generate adsorption force on the surface of the conveyor belt through the micropores, so that the cloth is adsorbed and closely attached to the surface of the conveyor belt when being inkjet printed, ensuring that the cloth is adsorbed and in a relatively flat state;

[0020] S4. After the cloth has passed the conveyor belt and completed printing, the cloth is rolled up in an arc state under the limit of the guide roller and the sleeve roller. At the same time, the space where the cloth is located at the guide roller is in a closed state. At the same time, the heating plate is started to generate heat in the closed space. The heat generated by the heating plate can act on the surface of the cloth to heat and dry the ink on the surface of the cloth. At the same time, the third motor is started. After the third motor is started, it can drive the diffusion wind wheel to rotate. With the operation of the diffusion wind wheel, the air in the space can circulate quickly, and the hot air can act evenly on the surface of the cloth to dry it.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] 1. When in use, when the inkjet printing device is in use, the winding of the cloth is in an arc state under the limit of the guide roller and the sleeve roller. At the same time, with the use of the closing plate and the cushion, the space where the cloth is located at the guide roller position is in a closed state. At the same time, the heating plate is started to generate heat in the closed space. The heat generated by the heating plate can act on the surface of the cloth to heat and dry the ink on the surface of the cloth. At the same time, because the cloth is in an arc state and in a small enclosed space at this time, the cloth in the arc state can accommodate a longer cloth in a small space, which improves the utilization rate of the hot air drying effect on the cloth surface. At the same time, the heat loss in the enclosed space is less, and the drying of the cloth completed by inkjet can consume less energy, which plays a role in energy saving and emission reduction, and meets the needs of green energy-saving and environmental protection development;

[0023] 2. When in use, the third motor is started while the cloth is being dried. After the third motor is started, it can drive the diffusion wind wheel to rotate. With the operation of the diffusion wind wheel, the air in the space can circulate quickly, and the hot air can evenly act on the surface of the cloth to dry it, thereby improving the drying efficiency of the cloth;

[0024] 3. When in use, as the conveyor belt runs, the cloth can be delivered as the cloth is rolled up. At the same time, the conveyor belt is in a breathable state through the micropores on the surface of the conveyor belt. At the same time, the fan is started, and the fan can generate adsorption force on the surface of the conveyor belt through the micropores, so that the cloth is adsorbed and adheres to the surface of the conveyor belt when being inkjet printed, ensuring that the cloth is adsorbed in a relatively flat state, avoiding wrinkles when the cloth is rolled up and affecting the processing quality.

The winding roller 405 and the unwinding roller 403 are matched with each other. The winding roller 405 is located between the two arc frames 502. When the inkjet printing device is used, the printing head 7 is used to complete inkjet printing on the cloth surface during the winding process, and starting the first motor 401 can drive the rotating shaft 402 to rotate.

After the cloth passes through the position of the conveyor belt 515 and completes the printing process, the cloth enters between the sleeve roller 506 and the guide roller 508 for guided transportation. At this time, the winding of the cloth is in an arc state under the limitation of the guide roller 508 and the sleeve roller 506. At the same time, with the use of the closing plate 518 and the cushion 3, the space where the cloth is located at the guide roller 508 is in a closed state, and the heating plate 511 is started at the same time, so that heat is generated in the closed space. The heat generated by the heating plate 511 can act on the surface of the cloth to heat and dry the ink on the surface of the cloth.

[0040] like Figure 5-Figure 7 As shown, the second motor 503 and the third motor 504 are both fixedly connected to the rear surface of the box body 1, the output end of the third motor 504 penetrates the box body 1 and extends to the inside, the output end of the third motor 504 is fixedly connected with a diffusion wind wheel 510, the diffusion wind wheel 510 is located between the closing plate 518 and the connecting rod 505, a soft pad 3 is arranged on the rear surface of the box door 2, the soft pad 3 matches the position of the closing plate 518, and the third motor 504 is started.

With the operation of the diffusion wind wheel 510, the air in the space can circulate quickly, and the hot air can evenly act on the surface of the cloth for drying, thereby improving the drying efficiency of the cloth. At the same time, because the cloth is in an arc state and in a smaller enclosed space at this time, the arc-shaped cloth can accommodate a longer cloth in a smaller space, thereby improving the utilization rate of the hot air drying effect on the cloth surface, and at the same time, the heat loss in the enclosed space is less, and less energy can be consumed for the drying of the inkjet-completed cloth.

[0041] like Figure 5-Figure 7 As shown, the output end of the second motor 503 passes through the box body 1 and extends to the inside, the output end of the second motor 503 is fixedly connected with an output shaft 512, the output shaft 512 passes through one of the arc frames 502 and is rotatably connected to the other arc frame 502, the outer surface of the arc frame 502 is rotatably connected with a support shaft 513, the support shaft 513 and the output shaft 512 are matched, and the outer surfaces of the support shaft 513 and the output shaft 512 are fixedly connected with a synchronous wheel 514, and the synchronous wheel 514 is located between the two arc frames 502. When the cloth passes over the conveyor belt 515 for inkjet printing, starting the second motor 503 can drive the output shaft 512 to rotate, and when the output shaft 512 rotates, it cooperates with the support of the support shaft 513 and the synchronous wheel 514 to drive the conveyor belt 515 to operate.

[0042] like Figure 5-Figure 7 As shown, a conveyor belt 515 is sleeved between the outer surfaces of the two synchronous wheels 514, and a plurality of micropores are evenly opened on the outer surface of the conveyor belt 515. A support seat 516 is fixedly connected between the two arc frames 502, and the support seat 516 is located at the inner side of the conveyor belt 515. A plurality of fans 517 are fixedly connected to the inner surface of the support seat 516. The fan 517 is in a suction state from top to bottom. The printing head 7 is located above the conveyor belt 515. With the operation of the conveyor belt 515, the cloth can be sent out following the winding of the cloth. At the same time, the micropores on the surface of the conveyor belt 515 are arranged to make the conveyor belt 515 in a breathable state. At the same time, the fan 517 is started, and the fan 517 can generate an adsorption force on the surface of the conveyor belt 515 through the micropores, so that the cloth is adsorbed and tightly attached to the surface of the conveyor belt 515 when being inkjet printed, ensuring that the cloth is in a relatively flat state when being adsorbed, and avoiding wrinkles when the cloth is wound and affecting the processing quality.

[0043] like Figure 5-Figure 7 As shown, the outer surfaces of the plurality of rotating rods 507 are fixedly connected with guide rollers 508, which are distributed in an arc shape, and the positions of the guide rollers 508 and the sleeve rollers 506 are matched. During processing, the unwinding roller 403 with the cloth rolled up is installed at the position of the rotating shaft 402, and the winding roller 405 for winding up the printed cloth is installed at the position of the connecting shaft 404. At this time, the cloth is pulled out from the position of the unwinding roller 403 to arrange the winding path of the cloth.

[0044] like Figure 8 As shown, a positioning roller 509 is symmetrically rotatably connected between the two arc-shaped frames 502, and the positioning roller 509 is located at the side of the conveyor belt 515. A plurality of telescopic rods 602 are equidistantly fixedly connected to the bottom of the side frame 601, and the outer surfaces of the plurality of telescopic rods 602 are sleeved with springs 603. A support 604 is fixedly connected between the lower end surfaces of the plurality of telescopic rods 602, and a pressure roller 605 is rotatably connected to the inner surface of the support 604, and the pressure roller 605 is located above the guide roller 508 and between the two guide rollers 508. After the cloth has been printed on the conveyor belt 515, it will pass between the pressure roller 605 and the positioning roller 509. At this time, the rebound force of the spring 603 can be used to apply downward pressure to the support 604. The support 604 can be supported and limited by the telescopic rod 602. At this time, the rebound force generated by the spring 603 can be used to make the pressure roller 605 press the positioning roller 509 below, and the cloth can be conveyed with a certain clamping force.

[0045] In the present invention, when the inkjet printing device is used, the ink is ejected from the nozzle by using the printing head 7 to form mist-like ink droplets and sprayed onto the surface of the cloth, thereby realizing inkjet printing processing on the cloth. During processing, the unwinding roller 403 with the cloth rolled up is installed at the position of the rotating shaft 402, and the winding roller 405 for winding up the cloth after printing is installed at the position of the connecting shaft 404. At this time, the cloth is pulled out from the position of the unwinding roller 403 to arrange the winding path of the cloth. The cloth first passes over the conveyor belt 515, then passes between the pressure roller 605 and the positioning roller 509, and then enters from the avoidance groove 519 on the lower side. The cloth passes through the arc path formed by the guide roller 508 and the sleeve roller 506, and is sent out in the reverse direction from the avoidance groove 519 above. At this time, the cloth The arrangement can be completed by putting it in the position of the winding roller 405, and then the cloth can be wound up. During the winding process, the printing head 7 is used to perform inkjet printing on the cloth surface. Starting the first motor 401 can drive the rotating shaft 402 to rotate, and the rotation of the rotating shaft 402 can drive the unwinding roller 403 to rotate for unwinding. At the same time, the connection between the second pulley 411, the belt 410 and the first pulley 409 can drive the driven shaft 407 to follow the rotation, and the meshing of the second gear 408 and the first gear 406 can drive the connecting shaft 404 to follow the rotation. The rotation of the connecting shaft 404 can drive the winding roller 405 to follow the rotation to complete the winding of the cloth. While the cloth passes over the conveyor belt 515 for inkjet printing, the second motor is started. The operation of 503 can drive the output shaft 512 to rotate. When the output shaft 512 rotates, it can drive the conveyor belt 515 to operate with the support of the support shaft 513 and the synchronous wheel 514. As the conveyor belt 515 operates, the cloth can be sent out following the winding of the cloth. At the same time, the micropores on the surface of the conveyor belt 515 are set to make the conveyor belt 515 in a breathable state. At the same time, the fan 517 is started. The fan 517 can generate an adsorption force on the surface of the conveyor belt 515 through the micropores, so that the cloth is adsorbed and adhered to the surface of the conveyor belt 515 when being inkjet printed, ensuring that the cloth is adsorbed in a relatively flat state, avoiding wrinkles when the cloth is wound and affecting the processing quality. After the cloth passes through the conveyor belt 515 and completes the printing process, the cloth passes through the pressure roller 6 05 and the positioning roller 509, at this time, the rebound force of the spring 603 can be used to apply pressure downward to the support 604, and the support 604 can be supported and limited by the use of the telescopic rod 602. At this time, the rebound force generated by the use of the spring 603 can make the pressure roller 605 press the positioning roller 509 below, and the cloth can be transported with a certain clamping force, and then the cloth enters between the sleeve roller 506 and the guide roller 508 for guided transportation. At this time, the winding of the cloth is in an arc state under the limitation of the guide roller 508 and the sleeve roller 506. At the same time, with the use of the closing plate 518 and the cushion 3, the space where the cloth is located at the guide roller 508 is in a closed state, and the heating plate 511 is started at the same time.Heat is generated in the enclosed space, and the heat generated by the heating plate 511 can act on the surface of the cloth to heat and dry the ink on the surface of the cloth. At the same time, the third motor 504 is started. After the third motor 504 is started, it can drive the diffusion wind wheel 510 to rotate. With the operation of the diffusion wind wheel 510, the air in the space can circulate quickly, and the hot air can act evenly on the surface of the cloth to dry it, which improves the drying efficiency of the cloth. At the same time, because the cloth is in an arc state and in a smaller enclosed space at this time, the arc-shaped cloth can accommodate a longer cloth in a smaller space, which improves the utilization rate of the hot air drying effect on the cloth surface. At the same time, the heat loss in the enclosed space is less, and the drying of the inkjet-finished cloth can consume less energy, which plays a role in energy saving and emission reduction, and meets the needs of green energy-saving and environmental protection development.

The model is selected according to the actual use, so the control method and wiring arrangement of the first motor 401, the second motor 503, the third motor 504, the heating plate 511 and the printing head 7 are no longer explained in detail.

A method for using a green and environmentally friendly inkjet printing device, characterized in that: The green and environmentally friendly inkjet printing device according to claim 9 is used, comprising the following steps: S1. When the inkjet printing device is used, during processing, the unwinding roller (403) with the cloth rolled up is installed at the position of the rotating shaft (402), and the winding roller (405) for winding up the cloth after printing is installed at the position of the connecting shaft (404). At this time, the cloth is pulled out from the position of the unwinding roller (403) to arrange the winding path of the cloth. The cloth first passes over the conveyor belt (515), then passes between the pressure roller (605) and the positioning roller (509), and then the cloth enters from the position of the avoidance groove (519) on the lower side. The cloth passes through the arc path formed by the guide roller (508) and the sleeve roller (506), and is sent out in the reverse direction from the upper avoidance groove (519). At this time, the cloth can be sleeved on the position of the winding roller (405) to complete the arrangement; S2. In the process of winding up, inkjet printing is performed on the surface of the fabric by using the printing head (7). The first motor (401) is started to drive the winding roller (405) to rotate to complete the winding of the fabric. When the fabric passes under the printing head (7), the printing head (7) is used to spray ink from the nozzle to form mist droplets and spray them onto the surface of the fabric, thereby achieving inkjet printing processing on the fabric. S3, as the conveyor belt (515) runs, the cloth can be delivered along with the winding of the cloth, and at the same time, the conveyor belt (515) is in a breathable state by setting the micropores on the surface of the conveyor belt (515), and at the same time, the fan (517) is started, and the fan (517) can generate an adsorption force on the surface of the conveyor belt (515) through the micropores, so that the cloth is adsorbed and closely attached to the surface of the conveyor belt (515) during inkjet printing, ensuring that the cloth is adsorbed and in a relatively flat state; S4. After the cloth has passed through the conveyor belt (515) and completed the printing process, the cloth is rolled up and placed in an arc state under the limit of the guide roller (508) and the sleeve roller (506). At the same time, the closing plate (518) and the cushion (3) are used to make the space where the cloth is located at the guide roller (508) in a closed state. At the same time, the heating plate (511) is started to generate heat in the closed space. The heat generated by the heating plate (511) can act on the surface of the cloth to heat and dry the ink on the surface of the cloth. At the same time, the third motor (504) is started. After the third motor (504) is started, it can drive the diffusion wind wheel (510) to rotate. With the operation of the diffusion wind wheel (510), the air in the space can circulate quickly, and the hot air can evenly act on the surface of the cloth to dry it.
