In the printing process, it is inevitable that some ink will splash or drip on the workbench. If it is not recovered, the ink will be wasted. The movement of the push plate can collect the scattered ink and push it into the ink tank. For example, in large-scale printing production, a small amount of ink may splash each time the printing operation is performed. After long-term accumulation, the recycled ink The amount of water is considerable, thus reducing the waste of ink. The rotating barrel rotates, and the acetone solvent inside the filter barrel is evenly dropped into the ink tank. Acetone has good solubility and can effectively dilute solvent-based inks, reducing the viscosity of the ink to a level suitable for printing. In plastic bag processing, when the viscosity of the ink increases due to long-term storage or temperature changes, adding an appropriate amount of acetone can adjust the fluidity of the ink. Butanone also has a strong solubility, and compared to acetone, its evaporation rate is slightly slower. It is used in some printing processes that do not require a particularly high drying speed, which can allow the ink to maintain better stability at the nozzle. BRIEF DESCRIPTION OF THE DRAWINGS

The pressing plate 408 is fixedly connected to the rear of the friction plate 307, the rotating plate 409 is in contact with the friction plate 307, the rotating barrel 407 is fixedly connected to the surface of the rotating plate 409, the filtering barrel 406 is fixedly connected to the inner wall of the ink tank 410, the bottom of the guide plate 404 is in contact with the top of the workbench 1, and the bottom of the push plate 405 is in contact with the workbench 1. The top of the table 1 is in contact, and the rotating barrel 407 is connected to the filter barrel 406 through the torsion spring. The friction plate 307 moves to drive the pressure plate 408 to move, and the pressure plate 408 moves to drive the rotating plate 409 to move, so that the rotating barrel 407 rotates, and the rotating barrel 407 rotates. The acetone solvent inside the filter barrel 406 is evenly dropped into the ink box 410 through the rotation of the rotating barrel 407. Acetone has good solubility and can effectively dilute solvent-based inks to reduce the viscosity of the ink to a level suitable for printing. In plastic bag processing, when the viscosity of the ink increases due to long-term storage or temperature changes, adding an appropriate amount of acetone can adjust the fluidity of the ink. Butanone also has a strong solubility, and compared with acetone, its volatilization speed is slightly slower. It is used in some printing processes that do not require a particularly high drying speed, which can keep the ink at the nozzle 203. Better stability.

[0021] A method for processing a printing device for processing plastic bags, comprising the following steps: Step 1: The reciprocating screw 204 is rotated by the motor 202, and the cross-shaped spiral groove on the reciprocating screw 204 drives the nozzle 203 to move left and right to print; Step 2: The nozzle 203 moves to drive the guide plate 211 to move, and the guide plate 211 moves to drive the Y-shaped plate 205 to move; Step 3: The Y-shaped plate 205 moves to drive the pressing roller 210 to move. The movement of the pressing roller 210 compresses the plastic bag, removes wrinkles on the plastic bag, and prevents uneven printing.

[0022] Working principle: The movement of the moving plate 1 305 drives the movement of the moving plate 2 401, the movement of the moving plate 2 401 drives the movement of the L-shaped plate 402, the movement of the L-shaped plate 402 drives the sliding rod 403, the movement of the sliding rod 403 drives the movement of the guide plate 3 404, the movement of the guide plate 3 404 drives the push plate 405 to move, the movement of the push plate 405 pushes the ink dropped on the workbench 1 into the ink tank 410, reducing the use cost during printing and avoiding waste. In the process of printing, it is inevitable that some ink will splash or drip on the workbench 1. If it is not recovered, the ink will be wasted. The movement of the push plate 405 can collect the scattered ink and push it into the ink tank 410, such as in large-scale printing. During production, a small amount of ink may splash out each time the printing operation is performed. After long-term accumulation, the amount of ink recovered is considerable, thereby reducing the waste of ink. The friction plate 307 moves to drive the pressing plate 408 to move, and the pressing plate 408 moves to drive the rotating plate 409 to move, so that the rotating barrel 407 rotates. The rotating barrel 407 rotates to evenly transfer the acetone solvent inside the filter barrel 406 into the ink box 410. Acetone has good solubility and can effectively dilute solvent-based inks to reduce the viscosity of the ink to a level suitable for printing. In plastic bag processing, when the ink increases in viscosity due to long-term storage or temperature changes, adding an appropriate amount of acetone can adjust the fluidity of the ink. Butanone also has a strong solubility, and compared with acetone, its volatilization rate is slightly slower. It is used in some printing processes that do not require a particularly high drying speed, which can keep the ink at the nozzle 203. Better stability.
