Definitions

  • the present invention relates to a printing device, and more specifically to a printing mechanism of an offset printing machine.
  • An offset printing machine is a lithographic printing machine in which when printing, a printed graphic is printed onto the rubber blanket of a transferring roller from the printing plate of a plating roller, and then transferred onto the paper from the transferring roller.
  • the printing mechanism of the offset printing machine includes a plating roller, a transferring roller and an imprinting roller, where the three rollers cooperate with each other to complete paper printing.
  • a web offset printing machine is an offset printing machine for printing a web material, whose existing printing method is an intermittent offset printing method. That is, regardless of the change in the printed pattern length of a printed matter, the outer diameters of the plating roller and the transferring roller are fixed. When the printed pattern length of the printed matter is changed, the maximum printable circumference of the plating roller is unequal to the printed pattern length of the printed matter. If the printed pattern length is less than the maximum printable length of the plating roller, a relatively large blank (an area without printed pattern) is generated between adjacent two printed patterns on the printed paper, which causes a large waste and thus is disadvantageous for printing.
  • a notch is designed on each of the plating roller and the transferring roller, and the two notches are set in synchronization correspondingly.
  • the printed matter such as paper and film
  • the printed matter is retracted under a driving force of a front and rear traction to eliminate the printing blank on the paper, while printing is performed when running in a forward direction, forming an back-and-forth intermittent printing method.
  • This printing method has the following obvious drawbacks in printing: on one hand, the printing speed is hard to go up, affecting printing efficiency; and on the other hand, the tension applied to the printed matter is not stable, which is prone to cause tensile deformation, affecting the printing accuracy and printing effect.

  • a curved groove is provided on the machine frame; the curved groove forms the transfer shaft running trajectory; the transfer shaft of the transferring roller is provided on the curved groove by a mounting base; the transfer shaft of the transferring roller is rotatably provided on the mounting base; and a position of the mounting base on the curved groove is adjustable.
  • the transfer shaft running trajectory is a circular arc trajectory; the transferring rollers of three different outer diameters are optionally selected; three axis positions of the transfer shaft are correspondingly provided on the circular arc trajectory; and each of the transferring rollers at the three axis positions maintains to abut and roll against the imprinting roller.
  • the three different outer diameters includes a maximum outer diameter, a minimum outer diameter, and an intermediate outer diameter, respectively.
  • a position of the imprinting roller on the machine frame is adjustable in the radial direction.
  • the transfer shaft is provided to rotate on a swinging arm; the swinging arm is swingably provided in the machine frame; and the circular arc trajectory of the transfer shaft running trajectory is formed by swinging the swing arm, and the position of the axis of the transfer shaft is adjustable on the circular arc trajectory.
  • the swinging arm is provided on the machine frame to swing by a swinging arm shaft; and a position of the swinging arm shaft on the machine frame is adjustable in the radial direction.

  • the driving device includes a pushing rod, a jacking rod, a cylinder transmission and a screw transmission;
  • the cylinder transmission includes a cylinder;
  • the screw transmission includes a screw, a nut and a slider;

  • the imprinting roller 2 is rotatably provided on a machine frame, and the imprinting roller is configured to be driven by the motor 19 (e.g., a servo motor) to rotate.
  • the plating roller 1 is correspondingly matched with the transferring roller 4. That is, the roller surface of the transferring roller 4 is correspondingly matched with a pattern unit on the plating roller 1 in N times, where N is a positive integer, preferably 1 or 2 for a convenience of the transferring of the printing pattern.
  • the roller surface of the transferring roller 4 can be just correspondingly matched with one pattern unit on the plating roller 1 (the relationship of 1 time); or, the roller surface (i.e., the outer surface circumference) of the roller 4 corresponds to two pattern units on the plating roller (the relationship of 2 times).

  • the transfer shaft 21 is configured to be driven by the motor 20 (e.g., a servo motor) to rotate, and drives the transferring roller 4 on the transfer shaft 21 to rotate.
  • a position of the axis of the transfer shaft 21 is adjustable on the transfer shaft running trajectory 40.
  • the position of the axis of the transfer shaft 21 on the transfer shaft running trajectory 40 is adjusted, so that each of the transferring rollers 4 of different outer diameters can maintain to abut and roll against the imprinting roller 2.
  • the transferring roller is correspondingly matched with the plating roller in outer diameter, and they maintain to abut and roll against each other while the transferring roller and the imprinting roller maintain to abut and roll against each other.
