Abstract
The invention discloses a cooling device for a printer distributing roller. The cooling device comprises a rotary tube, a rotating joint and a joint assembly, a transition piece and a fixed tube, wherein the rotating joint and the joint assembly are positioned outside the distributing roller; the transition piece is connected with the distributing roller; one end of the fixed tube is fixedly connected with the joint assembly; the other end of the fixed tube is matched with the transition piece through a bearing; and one end, which is positioned in a cavity of the distributing roller, of the rotary tube is connected with the transition piece and can rotate with the transition piece together. The cooling device for the printer distributing roller has the advantages of simple and compact structure, low cost, high reliability, long service life and the like and is convenient to assemble and disassemble.
Description
Technical field
The present invention is mainly concerned with the printing equipment field, refers in particular to a kind of printing machine wavers and uses cooling device.
Background technology
Printing machine is in printing process, because the rotation of the high speed of wavers (more than the 1500r/min) and axial float when contacting with other ink rollers, cause that the wavers surface heat has influenced the characteristic of printing ink then, will have influence on the quality of printing.
At present, traditional solution is exactly logical cooling water in the inside of wavers 1.As depicted in figs. 1 and 2; It is a kind of common warter connection device; One end of wavers 1 is provided with axle sleeve 3 and end cap 5; And through bearing 4 supportings, cooling water flows out from second joint 8 through wavers 1 inner hole 101 from the cavity of first joint 7 through copper pipe 2 (copper pipe) entering wavers 1 then.In this structure, swivel joint 6 is connected with the spindle nose of wavers 1 through threaded portion 601, when wavers 1 rotates at a high speed; Internal structure decision by swivel joint 6; The shell of swivel joint 6 can not rotate with wavers 1, and copper pipe 2 is welded on first joint 7, and first joint 7 links together with swivel joint 6 again; Obviously when wavers 1 rotation, copper pipe 2 is static relatively.And the length of copper pipe 2 is probably about 1000mm; This has just caused a problem, and copper pipe 2 flexibilities very long owing to length are very big, situation as shown in Figure 3 will occur; Bend near the unfixed left part of copper pipe 2; Formed a kind of imbalance, and also there is great difficulty pack into the inside of wavers 1 of so long copper pipe 2, dismounting is all inconvenient with maintenance.
Summary of the invention
The technical problem that the present invention will solve just is: to the technical problem that prior art exists, the present invention provides the printing machine wavers of a kind of simple and compact for structure, with low cost, easy accessibility, good reliability, long service life to use cooling device.
For solving the problems of the technologies described above, the present invention adopts following technical scheme:
A kind of printing machine wavers is used cooling device; It is characterized in that: comprise swivelling pipe, be positioned at wavers outside swivel joint and adapter assembly, transition piece and stationary pipes; Said transition piece links to each other with wavers; One end of said stationary pipes is fixedly connected with adapter assembly, and the other end of said stationary pipes cooperates with transition piece through bearing, and said swivelling pipe one end that is arranged in the wavers inner chamber connects with transition piece and can rotate with transition piece.
As further improvement of the present invention:
Said transition piece be connected with wavers through the threaded portion and through the location division wavers carry out in the radial direction spacing.
Be provided with sealing ring between the end of said transition piece and wavers.
Compared with prior art; The invention has the advantages that: printing machine wavers of the present invention is used cooling device; Simple and compact for structure, with low cost, good reliability through transition piece and swivelling pipe are set, can thoroughly solve copper pipe and bend and the inconvenient problem of dismounting maintenance.

The specific embodiment
Below will combine Figure of description and specific embodiment that the present invention is explained further details.
Like Fig. 4 and shown in Figure 5; Printing machine wavers of the present invention is used cooling device; Comprise swivelling pipe 10, be positioned at wavers 1 outside swivel joint 6 and adapter assembly, transition piece 9 and stationary pipes, transition piece 9 links to each other with wavers 1, and an end of stationary pipes 11 is fixedly connected (as welding) with adapter assembly; Adapter assembly comprises first joint 7 and second joint 8, and stationary pipes 11 is passed swivel joint 6 backs and welded together with first joint 7.The other end of stationary pipes 11 cooperates with transition piece 9 through second bearing 12, and the left end that is arranged in the swivelling pipe 10 of wavers 1 inner chamber is contained in wavers 1 one end spindle nose holes, gap 0.20～0.35mm; The other end connects with transition piece 9 and can rotate with transition piece 9.Like this, when wavers 1 rotation, swivelling pipe 10 can the phenomenon that swivelling pipe 10 ends bend or not occur with wavers 1 rotation.And stationary pipes 11 has relative rotation with wavers 9, but all there is support at stationary pipes 11 two ends, also the phenomenon of bending can not occur.Adopt between swivelling pipe 10 and the transition piece 9 to be threaded, guaranteed that cooling fluid can not reveal in the circulation of advancing and returning.
In the present embodiment, transition piece 9 be connected with wavers 1 through threaded portion 901 and through location division 902 wavers 1 carry out in the radial direction spacing.Be provided with sealing ring 13 between the end of transition piece 9 and wavers 1, sealing ring 13 can adopt the O RunddichtringO, is used for preventing the leakage of cooling fluid.
Below only be preferred implementation of the present invention, protection scope of the present invention also not only is confined to the foregoing description, and all technical schemes that belongs under the thinking of the present invention all belong to protection scope of the present invention.Should be pointed out that for those skilled in the art some improvement and retouching not breaking away under the principle of the invention prerequisite should be regarded as protection scope of the present invention.
