Embodiment Construction

[0015] Referring to Figures 1 to 3, the large imprinting cylinder of the satellite flexographic printing machine is a cylinder 2 with a central axis 1, and its feature is that the arc surface 3 of the cylinder 2 has three axes along the axial direction. Evenly distributed grooves 4, 5, 6, each groove 4 is rotated and fitted with a jaw shaft 7 arranged along the axis direction, and ten jaws 8 are fixed on a jaw shaft 7, and the jaws The jaw end 9 of 8 etc. is matched with the mouth edge of the groove 4, the driving end 10 of the jaw shaft 7 is on the side of the cylinder 2, and the notch 11 of each groove 4 is provided with two grooves arranged along the circumferential direction. The entrainment bridge plates 12 and 13 for supporting the entrainment, the top surface 14 of the entrainment bridge plate 12 is an arc surface with the same radian as the cylinder arc surface 3 .

[0016] In addition, the entrained bridge plate 12 is erected on the concave step 15 of the notch 11 of ...

Abstract

It relates to the compressing big roller for the satellite soft printing machine. It solves the inaccurate chromatograph and overall figure deviation and unable to introduce convex clamp to improve the printing quality. It features in the round cylinder with central axle, with the round arc surface of the round cylinder having more than one grooves distributed along the shaft, a clamping shaft along the axle inside each groove to coordinate with the rotation, each claws having the end matched with the mouth of the groove, drive end of the clamp shaft sticking out of one side of the round cylinder, over one clamping bridge plates supporting the clamping belt along the circumference at each groove notch, top of the clamping bridge plate surface sharing the same curve of the round cylinder.

Description

technical field [0001] The invention belongs to parts of printing equipment, and specifically refers to a large embossing cylinder of a satellite type flexographic printing machine suitable for sheet substrates (single substrates). Background technique [0002] The satellite flexo printing machine that has been widely used before has a printing structure consisting of a large impression cylinder and several printing plate units distributed around it. It is generally only suitable for printing on roll substrates. When printing, the substrate is attached to the The surface of the large embossing cylinder advances with the rotation of the large imprinting cylinder, and each time the substrate passes through a printing plate unit, it is overprinted with a picture and text of a color. The disadvantage of this kind of satellite flexographic printing machine is: when changing the printing length, the plate roller and its driving gear of the printing plate unit must be replaced; sin...
