a flow guide pipe (974) arranged at the output end of the peristaltic pump (973), wherein one end of the flow guide pipe (974) extends to the bottom end of the inner cavity of the ink box (91);
the scraping plate (975) is rotatably arranged at the left end of the guide plate (972) through a pin shaft, and a spring is arranged between the scraping plate (975) and the bottom of the guide plate (972);
the alcohol addition assembly (98) includes:
the piston cylinder (981) is arranged at the right end of the top of the ink box (91) along the front-back direction, and a plurality of liquid outlet holes (982) are formed in the lower surface of the piston cylinder (981) at equal intervals from front to back;
one end of the piston (983) is rotatably arranged at the rear end of the inner cavity of the piston cylinder (981) through a bearing, a piston hole (984) is formed in the outer wall of the piston (983) from front to back, and the position of the piston hole (984) corresponds to the liquid outlet hole (982);
one end of the second crankshaft (985) is arranged at the other end of the piston (983), and the other end of the connecting rod (96) is sleeved at the other end of the second crankshaft (985);
an alcohol tank (986) is mounted on the top end of the piston cylinder (981).
2. A printing unit for the production of plastic packaging bags according to claim 1, wherein the left side wall of the scraper (975) is arc-shaped and the arc is consistent with the outer wall of the printing roller (10).
3. Printing device for the production of plastic packaging bags according to claim 2, characterized in that the first crankshaft (93) and the second crankshaft (985) drive the connecting rod (96) to perform a circular movement with a uniform trajectory.
4. A printing process of a printing device for plastic packaging bag production according to claim 3, comprising the steps of:
step one, fixing a plastic coiled material on a supporting rod (4), and dragging the coiled material to be overlapped with a first guide roller (5), a second guide roller (6), a printing roller (10) and a third guide roller (7) in sequence, wherein the coiled material passes through between two static removing mechanisms (8), and the coiled material is coiled by coiling equipment to enable the coiled material to move from left to right;
when dust and static electricity are required to be removed from the coiled material, a dust suction fan (32) gives suction force to a tee joint (36) under the action of self suction force, so that negative pressure is formed in a dust cover (82), external gas is filtered by a filter cylinder (863) and then enters an air treatment box (861), an anion generator (862) is used for manufacturing oxygen ions, the oxygen ions flow along with the gas, a baffle plate (85) is used for shunting the gas, the gas is enabled to move along the surface of the coiled material under the blocking of a wind shield (84), the oxygen ions neutralize the surface charge of the coiled material, dust on the surface of the coiled material is sucked away by the gas, the gas carrying the dust enters an aeration pipe (34) through an air inlet pipe (35) and an air outlet pipe (33), the aeration pipe (34) discharges the gas in the form of small bubbles by utilizing the self small holes, and clean water stored in a water tank (31) is used for absorbing the dust, so that the gas is discharged after being purified, and the static electricity and the dust on the surface of the coiled material are eliminated;
step three, when printing is needed, the peristaltic pump (973) alternately extrudes and releases the guide pipe (974) to pump fluid, so that the ethanol ink in the ink tank (91) is conveyed to the guide plate (972), the ethanol ink flows to the printing roller (10) along the guide plate (972), the ethanol ink is adsorbed on the printing roller (10), the scraper (975) removes the excessive ethanol ink on the surface of the printing roller (10) along with the rotation of the printing roller (10), and the ethanol ink on the concave surface pattern of the printing roller (10) is smeared on the coiled material under the extrusion of the second guide roller (6) and the printing roller (10) on the coiled material, so that the printing of the coiled material is realized;
and fourthly, when the ethanol is required to be supplemented into the ethanol ink, the motor (95) drives the first crankshaft (93) and the stirring rod (92) to rotate, the stirring rod (92) stirs the ethanol ink in the ink tank (91), meanwhile, one end of the first crankshaft (93) pulls the connecting rod (96) to do circular motion, the other end of the connecting rod (96) drives the second crankshaft (985) to rotate, the purpose is to enable the piston (983) to rotate, when the piston hole (984) is communicated with the liquid outlet hole (982), the ethanol in the ethanol tank (986) passes through the piston hole (984) and the liquid outlet hole (982) to drop into the ethanol ink, and the volatilized ethanol in the ethanol ink is supplemented under the action of the stirring rod (92), so that the use effect of the ethanol ink is ensured.
