The invention relates to the technical field of packaging bag production equipment, and discloses a printing device of an industrial chemical bag. The printing device comprises a machine frame, a winding shaft, an unwinding shaft, a supporting plate, a printing unit and a leveling unit, wherein the leveling unit comprises two baffles, two leveling rollers and two movable plates, the two baffles are correspondingly fixed on the two sides of the supporting plate, the two movable plates are correspondingly hinged to one sides, close to the unwinding shaft, of the two baffles, torsion springs arefixed between the movable plates and the baffles, metal sheets are correspondingly fixed on the opposite surfaces of the baffles and the movable plates, the two metal sheets are in contact when the movable plates and the baffles are kept in a straight line, the two leveling rollers are rotationally connected to the machine frame, for the rotating directions of the two leveling rollers, rotation iscarried out from the bottom surface to the outer side of the supporting plate, the two leveling rollers are respectively connected with two motors, the two motors are connected in parallel, and the two motors are correspondingly connected with the metal sheets on the same side in series. According to the scheme, the problem that in the thin film printing process, a thin film is prone to be unevenand skewing, so that printing dislocation is caused is solved.
Description
technical field [0001] The invention relates to the technical field of packaging bag production equipment, in particular to a printing device for industrial chemical bags. Background technique [0002] The production process of industrial chemical bags generally includes design, printing and plate making, compounding, curing, slitting, bag making, and quality inspection to obtain finished products. Among them, printing plate-making refers to the process of making graphics or text originals into printing plates, coating the plates with color ink, and transferring the color ink to films or other substrates under pressure, and quickly copying in large quantities. craft. [0003] The patent document with the Chinese notification number CN104441949B discloses a bag-making printing machine with an inking device, including a frame and a support arranged on the frame, and the support is provided with an embossing cylinder that can lean against the film, An embossing shaft is fixed...
