[0054] As a technical optimization solution of the present invention, a printing process for producing antibacterial rayon printed fabrics comprises the following steps:

[0055] S1: fabric placement;

[0056] First, the fabric to be printed is wound around the upper rotating column 53, and then the retracting rods 530 on both sides are opened to place the card block 531 into the card slot 533, and then one end of the fabric passes through the scraper 22, the printer 494, and the outlet plate 390 in sequence, and finally one end of the fabric is wound around the lower rotating column 53.

[0057] S2: Fabric pressing:

[0058] The moving blocks 253 on both sides are driven to approach each other by the squeezing springs 252 on both sides. When the moving blocks 253 on both sides are approached, the guide rollers 255 on both sides contact the two sides of the fabric. At the same time, the pressing plates 29 on both sides press the fabric. At this time, the printing devices 494 on both sides contact the fabric under the action of the reset springs 33.

[0059] S3: Fabric printing:

[0060] The movable plate 36 is driven to move left and right in the guide groove 34 by opening the electric slider, and the printer 494 is turned on to facilitate synchronous printing on both sides of the fabric. Then, the bellows 490 is turned on to quickly dry the printed fabric. Then, the rotating column 53 on the upper side is driven to rotate by the electric slider. The rotating column 53 on the upper side is used to release and reel in the fabric on the upper and lower winding rods 532 through the pulley 59 and the belt 590.

[0061] When the present invention is used, the fabric to be printed is firstly wound around the upper rotating column 53, and then the contraction rods 530 on both sides are opened to place the card block 531 into the card slot 533, and then one end of the fabric is passed through the scraper 22, the printer 494, and the outlet plate 390 in sequence, and finally one end of the fabric is wound around the lower rotating column 53, and the extrusion springs 252 on both sides drive the moving blocks 253 on both sides to approach each other, and when the moving blocks 253 on both sides are close to each other, the guide rollers 255 on both sides contact the two sides of the fabric, and at the same time, the pressing plates 29 on both sides press the fabric. The printer 494 is turned on to quickly print both sides of the fabric at the same time. The scrapers 22 on both sides facilitate quick cleaning of both sides of the fabric while it is moving. The electric slider is turned on to drive the moving plate 36 to adjust left and right in the outer frame 3, so that the printing position on the fabric can be quickly and accurately adjusted while printing on both sides of the fabric. The electric slider is turned on to drive the T-plate 391 to adjust up and down in the lower slot 39. When the T-plate 391 is adjusted up and down, the outlet plate 390 is driven to adjust up and down synchronously, so as to achieve the adjustment of the tightness of the fabric during the continuous printing process.

[0062] By adjusting the forward or reverse rotation of the adjustment rod 45, the shift plate 46 is driven to move forward and backward. When the shift plate 46 moves forward and backward, it drives the slide plate 47 to adjust forward and backward in the through groove 43. When the slide plate 47 is adjusted forward and backward, the pressing range of the lower fabric is adjusted to facilitate the rapid air-drying operation after printing. By setting the pulley 59 and the belt 590, the upper rotating column 53 is driven to rotate synchronously with the lower rotating column 53, so that the upper and lower winding rods 532 can respectively realize the operations of placing and winding the fabric.

[0063] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments, and the above embodiments and descriptions are only for explaining the principles of the present invention.

4. A printing process for producing antibacterial rayon printed fabrics, comprising a printing device for producing antibacterial rayon printed fabrics as claimed in claim 3, characterized in that: The printing process comprises the following steps: S1: fabric placement; First, the fabric to be printed is wound around the upper rotating column (53), and then the retracting rods (530) on both sides are opened to place the card block (531) into the card slot (533), and then one end of the fabric is passed through the scraper (22), the printer (494), and the outlet plate (390) in sequence, and finally one end of the fabric is wound around the lower rotating column (53). S2: Fabric pressing: The moving blocks (253) on both sides are driven to approach each other by the squeezing springs (252) on both sides. When the moving blocks (253) on both sides are approached, the guide rollers (255) on both sides are in contact with both sides of the fabric. At the same time, the pressing plates (29) on both sides press the fabric. At this time, the printing devices (494) on both sides are in contact with the fabric under the action of the reset springs (33). S3: Fabric printing: The movable plate (36) is driven to move left and right in the guide groove (34) by opening the electric slider, and the printing device (494) is turned on to facilitate synchronous printing on both sides of the fabric. Then, the bellows (490) is turned on to quickly dry the printed fabric. Then, the rotating column (53) on one side is driven to rotate by the electric slider. The rotating column (53) on the upper side is driven by the pulley (59) and the belt (590) to unwind and reel the fabric on the upper and lower winding rods (532) at the same time.
