[0002] A digital inkjet printer is a device that uses digital printing technology for printing. It can achieve a high-efficiency printing method that starts with one sheet, does not require platemaking, and completes full-color images in one go. The advantages of a digital inkjet printer include low investment, low printing cost, optional printing size, high printing quality, small footprint, few operators and low operating costs. In addition, a digital inkjet printer can use professional digital printing inks to achieve printing effects with bright color saturation, wide color gamut and good transition.

[0003] Existing digital inkjets are often used in industries such as advertising, exhibitions, textile printing and dyeing, and decoration. For example, China's authorized patent for high-efficiency drying digital inkjet device (application number: CN202020289650.3) discloses a high-efficiency drying digital inkjet device, including an inkjet device main body, a drying box, a heating device, a spiral propeller, an exhaust fan, and an air outlet pipe. When the inkjet material belt enters the drying box, the heating device heats the box. At this time, the exhaust fan inputs external airflow into the box, and the airflow flows out of the box through the air outlet pipe, thereby accelerating the airflow velocity at the bottom of the drying box, which is beneficial to the Bernoulli principle and makes the gas at the top of the drying box flow downward, thereby driving the spiral propeller to improve the drying effect of the inkjet material belt.

[0004] Although the existing technology can effectively improve the drying effect of the drying equipment through the exhaust fan and the Bernoulli principle, when drying a relatively moist inkjet material belt, excessive drying treatment in a short period of time can easily cause the inkjet material belt to deform due to the principle of thermal expansion and contraction, thereby affecting the product quality; therefore, in order to solve the above problem, a green and environmentally friendly digital inkjet machine with a drying function and a method of use are proposed.

[0015] A method for using a green and environmentally friendly digital inkjet printer with a drying function, the specific implementation method comprising the following steps:

[0016] Step 1: According to the actual conditions of inkjet pattern, inkjet material, etc., the flow rate of the air outlet duct is adjusted. At this time, the staff starts the motor, so that the motor drives the screw rod to rotate, the screw rod drives the lifting slider to move, the lifting slider drives the telescopic plate to move, the telescopic plate drives the adjusting wheel to rotate, so that the adjusting wheel drives the limit slot to rotate, the limit slot drives the driving rod to move, and the driving rod drives the wind shield to move, so that a hexagonal through hole is formed between the wind shields, thereby realizing the adjustment of the flow rate in the air outlet duct;

[0017] Step 2: while adjusting the flow rate in the air outlet duct, the adjusting wheel drives the driving toothed plate to rotate, the driving toothed plate drives the driving gear to rotate, the driving gear drives the synchronous belt to rotate, the synchronous belt drives the rotating rod to rotate, the rotating rod drives the first bevel gear to rotate, the first bevel gear drives the second bevel gear to rotate, the second bevel gear drives the synchronous rod to rotate, the synchronous rod drives the first rotating plate to rotate, so that the first rotating plate drives one end of the second rotating plate to rotate, and the other end of the second rotating plate drives the protective slider to move along the guide block, thereby adjusting the degree of shielding of the third ventilation hole by the protective slider, and then adjusting the influence of the heat flow on the inkjet material belt;

[0018] Step 3: Put the inkjet material belt into the main body of the inkjet device, use the main body of the inkjet device to spray ink on the inkjet material belt, and start the drying device and the exhaust fan at the same time. After the inkjet material belt is sprayed, the main body of the inkjet device drives the inkjet material belt to move out of the main body of the inkjet device from one side of the main body of the inkjet device. When the main body of the inkjet device moves into the preheating box, the heat flow in the drying device enters the preheating box through the air outlet pipe, and the inkjet material belt in the preheating box is preheated to prevent the inkjet material belt from being deformed due to thermal expansion and contraction.

[0019] Step 4: The main body of the inkjet device continues to drive the inkjet material belt to move into the drying device. At this time, the heater installed in the drying device dries the ink on the surface of the inkjet material belt. At this time, the exhaust fan inputs the external airflow into the drying device, so that the air flow rate at the bottom of the drying device is greater than the air flow rate at the top, which is beneficial to the Bernoulli principle, thereby accelerating the airflow at the top of the drying device to move downward and improving the drying efficiency.

[0020] The present invention is beneficial in that:

[0021] 1. The present invention provides a preheating component, so that the inkjet material belt can stay in the preheating box before the inkjet material belt is dried. At this time, the heat flow in the drying device enters the preheating box through the air outlet pipe under the drive of the exhaust fan, thereby increasing the temperature in the preheating box and preheating the inkjet material belt. This avoids the problem that when the ink on the surface of the inkjet material belt is relatively wet, the inkjet material belt is directly moved to the drying device for drying. Due to the principle of thermal expansion and contraction, the inkjet material belt is easily deformed, resulting in an uneven surface and affecting the product quality. The applicability and reliability of the equipment are improved, the drying effect and efficiency of the inkjet material belt are improved, and the product quality of the inkjet material belt is improved;

[0022] 2. The present invention provides an adjustment component. Before drying the inkjet material strips with different humidity levels, the staff can rotate the adjustment wheel so that the adjustment wheel drives the wind shield to move along the adjustment slide groove through the limit groove and the drive rod, so that a hexagonal through hole is formed between the wind shields. The diameter of the hexagonal through hole is adjusted according to the actual situation of the ink on the surface of the inkjet material strip, thereby adjusting the air flow rate in the air outlet duct, thereby avoiding the problem that when drying the inkjet material strips with different humidity levels, if the heat flow rate is small, the preheating effect of the inkjet material strip is poor, resulting in the deformation of the inkjet material strip during drying; if the heat flow rate is large, the surface temperature of the inkjet material strip is easily increased too fast, resulting in the deformation of the inkjet material strip due to the principle of thermal expansion and contraction, affecting the product quality. The applicability of the equipment is improved, the preheating effect of the inkjet material strip is improved, thereby improving the drying effect of the inkjet material strip, and further improving the product quality of the inkjet material strip.

One side of the preheating box 7 is connected to the inkjet device body 1; by setting the preheating component, before the inkjet material strip 2 is dried, the inkjet material strip 2 can be allowed to stay in the preheating box 7. At this time, the heat flow in the drying device 3 enters the preheating box 7 through the air outlet pipe 5 under the drive of the exhaust fan 4, thereby increasing the temperature in the preheating box 7, preheating the inkjet material strip 2, and avoiding when the ink on the surface of the inkjet material strip 2 is relatively wet, directly moving it to the drying device 3 for drying, and avoiding the problem that the inkjet material strip 2 is prone to deformation due to the principle of thermal expansion and contraction, making the surface uneven, affecting the product quality, thereby improving the applicability and reliability of the equipment, improving the drying effect and drying efficiency of the inkjet material strip 2, and improving the product quality of the inkjet material strip 2.

[0037] A method for using a green and environmentally friendly digital inkjet printer with a drying function, the specific implementation method comprising the following steps:

[0038] Step 1: According to the actual conditions of the inkjet pattern and inkjet material, the flow rate of the air outlet pipe 5 is adjusted. At this time, the staff starts the motor, so that the motor drives the screw rod 19 to rotate, the screw rod 19 drives the lifting slider 18 to move, the lifting slider 18 drives the telescopic plate 17 to move, and the telescopic plate 17 drives the adjusting wheel 9 to rotate, so that the adjusting wheel 9 drives the limiting groove 10 to rotate, the limiting groove 10 drives the driving rod 11 to move, and the driving rod 11 drives the wind shield 12 to move, so that a hexagonal through hole is formed between the wind shields 12, thereby realizing the adjustment of the flow rate in the air outlet pipe 5;

At this time, the heater arranged in the drying device 3 dries the ink on the surface of the inkjet material belt 2. At this time, the exhaust fan 4 inputs the external airflow into the drying device 3, so that the air flow rate at the bottom of the drying device 3 is greater than the air flow rate at the top, which is beneficial to the Bernoulli principle, so that the airflow at the top of the drying device 3 is accelerated to move downward, thereby improving the drying efficiency.

[0042] Embodiment 2

[0043] See also Figure 2-3 , Figure 5-8As shown, in contrast to Example 1, as another embodiment of the present invention, the adjusting component includes an adjusting wheel 9 arranged on the outer wall of the air outlet pipe 5, a limiting groove 10 is evenly provided on one side of the adjusting wheel 9, and a driving rod 11 is slidably installed on the inner wall of the limiting groove 10, and a wind shield 12 is fixedly installed on one end of the driving rod 11, and an adjusting disk 13 is installed on one side of the wind shield 12, and an adjusting slide 14 is evenly provided on one side of the adjusting disk 13, and one end of the wind shield 12 is slidably installed on the inner wall of the adjusting slide 14, a first ventilation hole 15 is provided on one side of the adjusting wheel 9, and a second ventilation hole 16 is correspondingly provided on one side of the adjusting disk 13, and the diameter of the cross section of the first ventilation hole 15 and the second ventilation hole 16 is the same as the diameter of the cross section of the air outlet pipe 5, a driving component is provided on one side of the adjusting wheel 9, and a protective component for protecting the inkjet material belt 2 is provided on the other side of the adjusting wheel 9; by setting the adjusting component, when adjusting the inkjet material belt 2 with different humidity levels, Before drying, the staff can rotate the adjusting wheel 9 so that the adjusting wheel 9 drives the wind shield 12 to move along the adjusting slide groove 14 through the limit groove 10 and the driving rod 11, so that a hexagonal through hole is formed between the wind shield 12, thereby adjusting the diameter of the hexagonal through hole according to the actual situation of the ink on the surface of the inkjet material belt 2, thereby adjusting the air flow rate in the air outlet duct 5, avoiding the problem that when drying the inkjet material belt 2 with different humidity levels, if the heat flow rate is small, the preheating effect of the inkjet material belt 2 is poor, resulting in the inkjet material belt 2 being easily deformed during drying, and if the heat flow rate is large, the surface temperature of the inkjet material belt 2 is easily increased too fast, resulting in the inkjet material belt 2 being easily deformed due to the principle of thermal expansion and contraction, affecting the product quality. The applicability of the equipment is improved, the preheating effect of the inkjet material belt 2 is improved, thereby improving the drying effect of the inkjet material belt 2, and then improving the product quality of the inkjet material belt 2.

[0044] See also Figure 3 , Figure 5-6 As shown, the driving component includes a telescopic plate 17 arranged on one side of the adjusting wheel 9, and a lifting slider 18 is rotatably installed at one end of the telescopic plate 17. A screw rod 19 is threadedly installed on the inner wall of the lifting slider 18. The bottom end of the screw rod 19 passes through the support frame 6 and extends to the bottom end of the support frame 6. A motor is installed at the bottom end of the screw rod 19; by setting the driving component, when it is necessary to operate the adjusting component to adjust the flow rate in the air outlet duct 5, the staff can start the motor so that the motor drives the adjusting wheel 9 to rotate through the screw rod 19, the lifting slider 18 and the telescopic plate 17, thereby adjusting the flow rate in the air outlet duct 5. In addition, after the adjustment is completed, the position of the adjusting wheel 9 can be fixed by the screw rod 19 and the lifting slider 18, so as to avoid the adjusting wheel 9 from rotating easily, so that the diameter of the hexagonal through hole formed between the wind shield plates 12 changes, thereby reducing the accuracy of the adjusting component, affecting the preheating effect of the preheating component, and then affecting the drying effect of the inkjet material belt 2, thereby improving the stability and reliability of the equipment.

[0045] See also Figure 3-6 As shown, the protection component includes a driving toothed plate 20 arranged on one side of the adjusting wheel 9, a driving gear 21 is meshedly installed on one side of the driving toothed plate 20, a cylinder is fixedly installed on one side of the driving gear 21, a synchronous belt 22 is sleeved on the outer wall of the cylinder, a rotating rod 23 is sleeved on one end of the synchronous belt 22, a first bevel gear 24 is fixedly installed on one end of the rotating rod 23, a second bevel gear 25 is meshedly installed on one side of the first bevel gear 24, a synchronous rod 26 is fixedly installed on one side of the second bevel gear 25, a first rotating plate 27 is evenly rotatably installed on the outer wall of the synchronous rod 26, a second rotating plate 28 is rotatably installed on one end of the first rotating plate 27, a protective slider 29 is rotatably installed on the end of the second rotating plate 28 away from the first rotating plate 27, a protective plate 30 is slidably installed on the top of the protective slider 29, one end of the protective plate 30 is fixedly installed on the inner wall of the preheating box 7, and a third ventilation hole 31 is evenly opened on the top of the protective plate 30; by setting the protection Component, when adjusting the flow rate in the air outlet pipe 5, the adjusting wheel 9 drives the driving tooth plate 20 to rotate, so that the driving tooth plate 20 drives the protective slider 29 to move through the driving gear 21, the synchronous belt 22, the rotating rod 23, the first bevel gear 24, the second bevel gear 25, the synchronous rod 26, the first rotating plate 27 and the second rotating plate 28, and adjusts the degree of blocking of the third ventilation hole 31 by the protective slider 29, so as to avoid the problem that when the heat flow rate in the air outlet pipe 5 is fast, the heat flow directly preheats the bottom end of the inkjet material belt 2, which is easy to cause the inkjet material belt 2 to deform and affect the product quality. When the flow rate in the air outlet pipe 5 is fast and the flow rate is small, the direct contact between the heat flow and the inkjet material belt 2 can be reduced, and the inkjet material belt 2 is protected. When the flow rate in the air outlet pipe 5 is slow and the flow rate is large, the direct contact between the heat flow and the inkjet material belt 2 can be increased, so that the inkjet material belt 2 is fully preheated, and the preheating effect of the inkjet material belt 2 is improved.

[0046] See also Figure 5-6 As shown, a guide block 32 is slidably installed at the bottom end of the protection slider 29, and the guide block 32 is fixedly installed at the bottom end of the protection plate 30; it can guide and limit the protection slider 29 when the protection slider 29 slides, thereby avoiding the problem that the protection slider 29 is easily offset or rotated downward when the protection slider 29 slides, making it difficult for the protection slider 29 to block the third ventilation hole 31, thereby reducing the protection effect of the protection component, thereby improving the stability and reliability of the protection component.

[0047] See also Figure 3-5As shown, there is a gap between the two sides of the protection plate 30 and the inner wall of the preheating box 7; the heat flow in the preheating box 7 can move from the bottom of the preheating box 7 to the top of the preheating box 7 through the gap, thereby promoting the gas circulation in the preheating box 7, avoiding the problem that when the protection slider 29 completely blocks the third ventilation hole 31, the flow rate of the heat flow is slow, resulting in uneven air temperature in the preheating box 7, thereby reducing the preheating effect on the inkjet material strip 2, and then affecting the drying effect of the inkjet material strip 2, making the air temperature distribution in the preheating box 7 more uniform, thereby improving the preheating effect on the inkjet material strip 2.

[0048] See also Figure 3 As shown, the third ventilation holes 31 are arranged at one end of the protective plate 30 away from the drying device 3, and are staggered between two adjacent third ventilation holes 31; when the air flow rate in the air outlet pipe 5 is increased, the heat flow can contact the bottom end of the inkjet material strip 2 more evenly, thereby improving the preheating effect of the inkjet material strip 2, and further improving the drying effect of the inkjet material strip 2.

[0049] See also Figure 3 and Figure 5 As shown, the distance between the top and bottom of the driving tooth plate 20 is greater than the maximum distance from the top of the lifting slider 18 to the top of the screw rod 19; the driving tooth plate 20 can always be meshed with the driving gear 21, avoiding the problem that when the distance between the top and bottom of the driving tooth plate 20 is small, the driving tooth plate 20 easily stops meshing with the driving gear 21, making the driving gear 21 easy to deflect, thereby causing the stability of the protection component to decrease, resulting in a decrease in the protection effect, thereby improving the stability and reliability of the protection component.

[0050] Working principle: before inkjet the inkjet material belt 2, the staff can start the motor, so that the motor drives the screw rod 19 to rotate, the screw rod 19 drives the lifting slider 18 to move, the lifting slider 18 drives the telescopic plate 17 to move, the telescopic plate 17 drives the adjusting wheel 9 to rotate, so that the adjusting wheel 9 drives the limiting groove 10 to rotate, the limiting groove 10 drives the driving rod 11 to move, and the driving rod 11 drives the windshield plate 12 to move, so that a hexagonal through hole is formed between the windshield plates 12. When the ink on the surface of the inkjet material belt 2 is relatively moist, the diameter of the hexagonal through hole can be increased, the heat flow rate can be reduced and the heat flow rate can be increased, thereby extending the residence time of the heat flow in the preheating box 7, and increasing the temperature in the preheating box 7, so that the inkjet material belt 2 is fully preheated. When the ink on the surface of the inkjet material belt 2 is relatively dry, the diameter of the hexagonal through hole can be reduced, the heat flow rate can be increased and the heat flow rate can be reduced, so as to avoid the problem that the temperature is too high and the inkjet material belt 2 is dried quickly and easily deformed. At the same time, the adjusting wheel 9 drives the driving tooth plate 20 to rotate. The driving gear plate 20 drives the driving gear 21 to rotate, the driving gear 21 drives the synchronous belt 22 to rotate, the synchronous belt 22 drives the rotating rod 23 to rotate, the rotating rod 23 drives the first bevel gear 24 to rotate, the first bevel gear 24 drives the second bevel gear 25 to rotate, the second bevel gear 25 drives the synchronous rod 26 to rotate, and the synchronous rod 26 drives the first rotating plate 27 to rotate, so that the first rotating plate 27 drives one end of the second rotating plate 28 to rotate, and the other end of the second rotating plate 28 drives the protective slider 29 to move along the guide block 32, so as to adjust the degree of shielding of the third ventilation hole 31 by the protective slider 29. When the diameter of the hexagonal through hole is increased, the protective slider 29 reduces the degree of shielding of the third ventilation hole 31, so that the heat flow can directly preheat the inkjet material belt 2 through the third ventilation hole 31, thereby increasing the preheating effect. When the diameter of the hexagonal through hole is reduced, the protective slider 29 increases the degree of shielding of the third ventilation hole 31, thereby preventing the heat flow from directly preheating the inkjet material belt 2, thereby reducing the risk of deformation of the inkjet material belt 2.

[0051] After the flow rate in the air outlet pipe 5 is adjusted, the inkjet material belt 2 is placed in the inkjet device body 1 for inkjet, and the drying device 3 and the exhaust fan 4 are started at the same time. After the inkjet material belt 2 is finished being inkjetted, the inkjet material belt 2 is driven by the inkjet device body 1 to move out of the inkjet device body 1 from one side of the inkjet device body 1. When the inkjet device body 1 moves into the preheating box 7, the heat flow in the drying device 3 enters the preheating box 7 through the air outlet pipe 5 to preheat the inkjet material belt 2 in the preheating box 7 to prevent the inkjet material belt 2 from being deformed due to the thermal expansion and contraction effect. At this time, the inkjet device body 1 continues to drive the inkjet material belt 2 to move into the drying device 3. At this time, the heater arranged in the drying device 3 dries the ink on the surface of the inkjet material belt 2. At this time, the exhaust fan 4 inputs the external airflow into the drying device 3, so that the air flow rate at the bottom of the drying device 3 is greater than the air flow rate at the top, which is beneficial to the Bernoulli principle, so that the airflow at the top of the drying device 3 is accelerated to move downward, thereby improving the drying efficiency.
