The front head support bar and the rear head support bar slide, so that the machine head running bar is located at the far left of the front head support bar and the rear head support bar, the second motor stops working, and the first motor drives the nozzle The assembly slides along the running bar of the machine head, so that the nozzle assembly is located at the front of the running bar of the machine head, and the first motor stops working, thereby completing the initial setting of the machine head assembly, and then the third motor jointly drives the first left support bar and The first right support rod rises and falls, thereby adjusting the distance between the first flat plate and the nozzle assembly to a size suitable for printing; when printing, it will be necessary to print an upright image viewed from left to right and an inverted image viewed from left to right The same image is transmitted to the printing control system of the nozzle assembly in sequence, and then the first motor drives the nozzle assembly to slide back and forth along the running bar of the machine head, and the first fabric located on the upper side of the first flat plate is viewed from left to right. The vertical image is printed with a printing width, and then the second motor drives the head to run the cross bar along the front head support cross bar and the rear head support cross bar from left to right to slide a print width until the first fabric is finished Looking at the whole printing of the upright image from left to right, the head running cross bar is positioned at the far right of the front head support cross bar and the rear head support cross bar this moment; then the first left connecting roller and the first right connecting roller The rotating rollers are jointly driven by the fifth motor to rotate 180 degrees, so that the second fabric is directly under the nozzle assembly, and then the first motor drives the nozzle assembly to slide back and forth along the running bar of the machine head, and the second fabric is processed from right to left. Look at the upright image for a printing width of printing, and then the second motor drives the running bar of the machine head to slide from right to left along the supporting bar of the front machine head and the supporting bar of the rear machine head for one printing width until the completion of the first The full printing of the upright image is viewed from right to left on the second fabric so that the exact same printing is done on the first fabric and the second fabric, At this time, the head running cross bar is located at the far left of the front head support cross bar and the rear head support cross bar; One plate is unloaded from the plate support system, so that the first plate is in the unloaded state, and then the third motor jointly drives the first left support rod and the first right support rod to descend, and at the same time, the fourth motor jointly drives the second left support rod And the second right support bar rises, so that the distance between the second flat plate and the nozzle assembly is suitable for printing, and the height of the second flat plate is higher than the height of the first left support bar and the first right support bar, and the printing is completed. Replacement of the flat plate, and then the first motor drives the nozzle assembly to slide back and forth along the running bar of the machine head, and prints a printing width of the third fabric located on the upper side of the second flat plate, looking upright from left to right, and then The second motor drives the head running cross bar to slide a print width from left to right along the front head support cross bar and the rear head support cross bar until the third fabric is viewed from left to right to complete the upright image. All printing, at this moment, the running bar of the machine head is located at the far right of the supporting bar of the front machine head and the supporting bar of the rear machine head; degree, so that the fourth fabric is directly under the nozzle assembly, and then the first motor drives the nozzle assembly to slide back and forth along the running bar of the machine head, and the fourth fabric is printed with a printing width of the upright image viewed from right to left , and then the second motor drives the running bar of the machine head to slide from right to left along the supporting bar of the front machine head and the supporting bar of the rear machine head for a printing width until the fourth fabric is erected from right to left The entire printing of the image, so as to complete the same printing on the third fabric and the fourth fabric. At this time, the running bar of the machine head is located at the far left of the supporting bar of the front machine head and the supporting bar of the rear machine head. When the 3rd fabric and the 4th fabric were printed, the stitching between the first fabric and the second fabric positioned on the first flat plate that had completed the printing was removed, and the first fabric and the second fabric were taken off, and then the first fabric and the second fabric were removed. A left connecting roller and the rotating roller of the first right connecting roller are connected with the connecting roller, so that the first flat plate is installed on the flat support system, so that the first flat plate is in the installed state, and the fifth fabric waiting for printing is spread on the first flat plate At the same time, the sixth fabric is closely attached to the lower side of the first plate, and then the front, rear, left and right sides of the fifth fabric and the sixth fabric are sewed together, so that the fifth fabric and the sixth fabric The fabric forms a closed bag and is placed on the first flat plate to complete the replacement of the fabric until the printing of all the fabrics that need to be printed is completed.
