Abstract
The utility model discloses a cooling device used for a distributing roller of a printing machine. The cooling device comprises a rotating pipe, a rotating joint, a joint assembly, a transition piece and a fixing pipe, wherein the rotating joint and the joint assembly are arranged outside the distributing roller; the transition piece is connected with the distributing roller; one end of the fixing pipe is fixedly connected with the joint assembly; the other end of the fixing pipe is matched with the transition piece through a bearing; and one end of the rotating pipe in an inner cavity of the distributing roller is connected with the transition piece and can rotate along with the transition piece. The cooling device has the advantages of simple and compact structure, low cost, convenient disassembling and assembling, good reliability, long service life and the like.
Description
Technical field
The utility model is mainly concerned with the printing equipment field, refers in particular to a kind of printing machine wavers 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 at the 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 by bearing 4 supportings, cooling water from first joint 7 by copper pipe 2(copper pipe) enter the cavity of wavers 1, flow out from second joint 8 by the hole 101 of wavers 1 inside then.In this structure, swivel joint 6 is connected with the spindle nose of wavers 1 by 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, because copper pipe 2 flexibilities that length is very long are very big, situation as shown in Figure 3 will appear, 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 and maintenance are all inconvenient.
The utility model content
The technical problems to be solved in the utility model just is: at the technical problem that prior art exists, the utility model provides the printing machine wavers cooling device of a kind of simple and compact for structure, with low cost, easy accessibility, good reliability, long service life.
For solving the problems of the technologies described above, the utility model by the following technical solutions:
A kind of printing machine wavers cooling device, it is characterized in that: comprise swivelling pipe, be positioned at swivel joint and adapter assembly, transition piece and the stationary pipes of wavers outside, described transition piece links to each other with wavers, one end of described stationary pipes is fixedlyed connected with adapter assembly, the other end of described stationary pipes cooperates with transition piece by bearing, and described 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 utility model:
Described transition piece be connected with wavers by the threaded portion and by the location division wavers carry out in the radial direction spacing.
Be provided with sealing ring between the end of described transition piece and wavers.
Compared with prior art, advantage of the present utility model is: the utility model printing machine wavers cooling device, simple and compact for structure, with low cost, good reliability by 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 with reference to Figure of description and specific embodiment the utility model is described in further details.
As shown in Figure 4 and Figure 5, printing machine wavers cooling device of the present utility model, comprise swivelling pipe 10, be positioned at swivel joint 6 and adapter assembly, transition piece 9 and the stationary pipes of wavers 1 outside, transition piece 9 links to each other with wavers 1, one end of stationary pipes 11 is fixedlyed connected with adapter assembly (as welding), 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 by 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 by threaded portion 901 and by 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 utility model, protection domain of the present utility model also not only is confined to the foregoing description, and all technical schemes that belongs under the utility model thinking all belong to protection domain of the present utility model.Should be pointed out that for those skilled in the art the some improvements and modifications not breaking away under the utility model principle prerequisite should be considered as protection domain of the present utility model.
