Abstract

The utility model discloses a cylinder roller bearer structure on a printing machine. The cylinder roller bearer structure comprises a plate cylinder, a rubber cylinder and an impression cylinder, wherein the plate cylinder, the rubber cylinder and the impression cylinder are supported by wallboard shaft sleeves, the three cylinders are assembled by cylinder bodies, shaft necks, roller bearers, shaft heads and gears, the roller bearers are in conical shapes, and the roller bearers are in interference fit with the three cylinders. According to the cylinder roller bearer structure on a printing machine disclosed by the utility model, the roller bearers are in the conical shapes, axial regulation amount of the three cylinders can be converted into radial change of a roller bearer on the rubber cylinder relative to a roller bearer on the impression cylinder, better contact of the roller bearers of the rubber cylinder and the impression cylinder can be still kept even the center distance of two cylinders changes, the three cylinders can be used for printing again just by cleaning the three cylinders after the three cylinders are axially regulated the operation is convenient and flexible, and the time and labor are saved.

Description

Cylinder on the printing machine walks to take on iron construction

Technical field:

The utility model relates to a kind of cylinder and walks to take on iron construction, is specially adapted to use on the printing machine.

Background technology:

Generally there are three swifts to constitute in the printing machine, by plate cylinder 1 blanket cylinder 2 and impression cylinder 3, abbreviate cylinder as, this three swift all is by barrel, shoulder iron, axle journal and spindle nose are formed, cylinder is supported on the wallboard axle sleeve, rotated by gear driven, have only barrel to divide between per two cylinders and keep contact, guarantee certain pressure, just can make printing ink fully shift (see figure 1) betwixt, cylinder is for the corresponding rubber of assembling and sting paper tooth etc., whole stack shell has designed neutral (as shown in Figure 1a), cross in the neutral process rolling at cylinder so, lost squeegee pressure, and because of the gap between cylinder spindle nose and the axle sleeve, cylinder is whenever circled produce once vibration, to directly influence the printing machine print quality, though cylinder has taked to walk to take on iron construction at present, contact to realize by the cylindrical shoulder iron between the cylinder, but just change as the centre-to-centre spacing between forme and rubber and the impression cylinder, cause cylinder to walk to take on iron construction and can not realize good roll extrusion state, do not realize real effect.

Summary of the invention:

Task of the present utility model is to propose a kind ofly to realize excellent contact in cylinder roll extrusion process, avoids two rolling impacts between the cylinder, and the running cylinder on a kind of printing machine stably walks to take on iron construction.

Task of the present utility model is finished like this, cylinder on the printing machine walks to take on iron construction, it comprises that plate cylinder, blanket cylinder and impression cylinder are supported by the wallboard axle sleeve, cylinder is by stack shell, axle journal, shoulder iron and spindle nose and gear assembling, it is characterized in that: described shoulder iron is shaped as interference fit between taper shape and the cylinder.

The utlity model has following effect: shoulder iron of the present utility model is for conical, the shoulder iron phase that the amount of cylinder axial adjustment changes on the blanket cylinder is takeed on iron in the variation of radial direction to impression cylinder, even the centre-to-centre spacing of two cylinders changes, blanket cylinder still can keep good the contact with the shoulder iron of impression cylinder, cylinder carries out only needing cylinder is cleaned and can print again after the axial adjustment, and is easy to operate, flexibly, save time, laborsaving.

Description of drawings:

Fig. 1 is the structural representation of prior art cylinder; Fig. 2 is the prior art structural representation; Fig. 3 is structural representation of the present utility model.

Drawing explanation: 1, plate cylinder, 2, blanket cylinder, 3, impression cylinder, 4, gear, 5, spindle nose, 6, the wallboard axle sleeve, 7, shoulder iron, 8, axle journal.

The specific embodiment:

Describe embodiment in detail in conjunction with above accompanying drawing, prior art is supported by wallboard axle sleeve 6 by plate cylinder 1, blanket cylinder 2 and impression cylinder 3, drive rotation by gear 4, cylinder is by stack shell, axle journal 8 and shoulder iron 7 and spindle nose assembling, the technical solution of the utility model is that shoulder iron 7 is interference fit between taper shape and the cylinder, because shoulder iron has tapering, can realize good contact in cylinder roll extrusion process, thereby avoided the rolling impact between two cylinders, realized that running steadily.

Claims

1. the cylinder on the printing machine walks to take on iron construction, it comprises that plate cylinder, blanket cylinder and impression cylinder are supported by the wallboard axle sleeve, cylinder is by stack shell, axle journal, and shoulder iron and spindle nose and gear assemble, and it is characterized in that: described shoulder iron is shaped as interference fit between taper shape and the cylinder.
