  Looking at the operation state,

The ink is filled in the main ink container 100 by the level switches 103 embedded in the plurality of main ink containers 100 embedded in a drawer (not shown) inside the lower right cover 11 of the main body 1 of the lower right side part 10. After charging

  As shown in FIGS. 9 and 10, the ink of the plurality of main ink containers 100 is supplied to the plurality of auxiliary ink containers 200 by the first supply device.

  The operation of the first supply device is that when the ink pump 105 is operated, ink continues to pass through the ink pump 105 through a hose 109 connected to the main ink container built-in filter 102 embedded in the main ink container 100. Then, after flowing the ink through the filter 120 and the non-return check valve 130 provided in the hose 109 connected to the ink pump 105 into the auxiliary ink container 200,

 The ink supplied to the auxiliary ink container 200 is installed at the bottom and heated to a predetermined temperature by a fixing and heating device for heating to a predetermined temperature,

  After the ink is heated in the auxiliary ink container 200, the cartridge heater 245 and the thermoelectric element 270 are operated by the central control, and the auxiliary ink container placed on the upper portion of the cartridge heater 245 and the thermoelectric element 270 is operated. Heat 200 to maintain a constant temperature regardless of ambient temperature,

  The auxiliary ink container 200 operates the vacuum hose 309 connected to the inside and the vacuum pump 300 connected to the other side to be a predetermined vacuum pressure to the vacuum tank 310 at the set pressure, and then the vacuum tank By operating the three-phase valve 350 connected to the middle one side of the vacuum hose 309 connected to the 310 and the auxiliary ink container 200, to maintain the vacuum pressure inside the apparatus including the auxiliary ink container 200, ( 9 and 11) The three-phase valve 350 is operated by the instruction of the head ink purge setting circuit 400 installed on the other side of the three-phase valve 350 to block the vacuum tank 310, and the air When injected into the auxiliary ink container 200 through the three-phase valve 350, the stop vacuum valve 220 connected to the discharge hose 109 connected by the auxiliary ink cylinder upper nipple 204 connected to one side of the auxiliary ink container 200 Through the main holder to transfer the desired pressure and ink volume to the main holder for printing It is.

   As shown in Fig. 14, the head slipping station places the solution in the solution chamber 1200 in the ink purge and solution chamber 1000, and wets the inside of the apparatus with the solution.

    After completing the assembly by placing the printhead on the top, and selecting one of the two air hoses connected to the air cylinder 1600, the ink purge and solution chamber (by the speed controller 1610 located in the middle of the air hose) As the air cylinder 1600 is moved up and down along the two upper and lower guide guides 1300 attached to the lower part of the 1000, the print head installed on the top of the head slipping station is moved up and down together,

  In this case, when ink is supplied through the head connector 1910 through a hose (not shown) in the ink supply device, the printhead is installed at the lower portion of the head connector 1910.

Sprayed by the nozzle 1920 to print,

  The nozzle 1920 is fixed by the jig 1940 installed on the rear surface of the nozzle 1920, and the method of precisely printing by adjusting the position.

  The fabric is positioned below the profile 2300 and at the same time, the signal of the motion detector 2450 and the X-axis left profile fixing part 2100 installed at regular intervals on the central control control (not shown) and the profile 2300. When the DC gear motor 2122 of the X-axis left profile fixing part 2100 is operated by an encoder installed at the upper and lower parts of the coupling, the coupling 2205 and the bearing (2205) are mounted on the upper part of the DC gear motor 2122. When the timing gear 2112 connected by 2111 starts to rotate, a timing belt 2700 fixed to the idle pulley 2506 of the timing gear 2112 and the X-axis idle roller fixing part 2500 is a profile 2300. A certain distance is spaced apart along the stop) by the instruction of the motion detector 2450 installed at a predetermined interval spaced on the profile (2300) and at the same time spaced at a constant interval on the profile (2300), the movement distance is installed in the rear Absolute value of Two motion detectors 2241 for absolute value sending large and minimum signals, and two motion detectors 2450 for width adjustment, which are installed at a predetermined interval in front, are rotated in reverse and attached to the timing belt 2700. It is a method of printing the width of the picture by spraying the ink of the type and amount determined by the given head to the fabric, and repeating this operation.

As shown in Figures 18 to 21, the fabric is printed while the fabric flowing from the rear guide roll 5300 of the main body 1 passes through the Y-axis media roll (5200) in the upper center of the Y-axis media roll ( 5200 is heated and dried while passing through the upper portion of the bed heater 5000 is installed horizontally passed through the fabric,

 Bed heater upper groove 5002 or

Heat dried by a heater built between the bed heater central step (5005) and the bed heater front and rear step (5006),

  Heat and dry while passing through the front surface of the vertically arranged bed heater 5000 installed in the front lower portion of the guide roll (5300) installed on the front of the bed heater (5000)

 Bed heater upper groove 5002 or

Heat-dried by a heater built in between the bed heater central step (5005) and the bed heater front and rear step (5006),

  The vertically installed bed heater 5000 and a plurality of fans 5510 of the dry fan 5500 installed on the front of the bed heater are operated to dry the descending fabric.

  The present invention as described above can be printed in the best quality by facilitating ink penetration by heating the printing portion to the appropriate temperature by using a triple drying system using two bed heaters and a dry fan,

By using the rotary encoder of the digital printer, the width of the figure, that is, the X-axis spacing is controlled by artificially adjusting the limit value by using a rotary encoder instead of the linear encoder using the conventional linear stream. To control and eliminate the downtime

 In order to prevent clogging by drying the printing ink supplied with 8 heads, it is composed of a wet device that wets the device as a solution to extend the clarity and life of the print, and the nozzle is provided by a jig installed at the rear of the nozzle. Can be printed precisely by fixing and positioning.

 The main ink container is a large capacity of about 1800CC, and the same level as the auxiliary ink container has a built-in level switch for each color to send a signal to the central control control when the ink is insufficient to be charged, and is installed on one side of the hose connected to the pump connected to the main ink container. By supplying ink to the auxiliary ink container through the filter, it improves the disadvantage of clogging by the residue in the device and maintains the constant temperature regardless of the ambient temperature change by maintaining the constant temperature by the cartridge heater and the thermoelectric element installed under the auxiliary ink container. By supplying the correct amount of ink, the vacuum is released in the vacuum state through the three-phase valve, and the constant pressure control to inject the correct amount of ink into the main holder reduces the nozzle clogging phenomenon. There is an effect that can be done.
