Abstract

The utility model discloses a cooling roller device of a gravure printer. A cooling roller is respectively supported in a wallboard A and a wallboard B through a bearing A and a bearing B, the water feeding end of the cooling roller close to the external surface of the wallboard A is provided with a sealing seat B, a sealing seat A and an end cover in sequence, a cavity C is arranged between the contact surfaces of the sealing seat A and the sealing seat B, the cavity of the cooling roller is provided with a water feeding pipe, a backwater channel is arranged between the water feeding pipe and the inner circle of the cooling roller, a baffle is arranged in the end cover and divides the cavity of the end cover into a cavity A and a cavity B, and the cavity A and the cavity B are respectively provided with a backwater pipe B and a backwater pipe A. The device realizes the follow-up operation of the cooling roller and a membrane and also the low damping operation; and the three-cavity sealing mode is adopted, no oil seals or other sealing parts generating resistance are needed, and the bearings are isolated to ensure that the bearings can not be contacted with cooling water and corrosion of the bearings can be prevented; and the eccentric backwater cavity can better ensure backwater flow.

Description

A kind of intaglio press cooling roller device

Technical field

The utility model belongs to the printing machinery technical field, relates to a kind of intaglio press cooling roller device.

Background technology

At present, the set type intaglio press is undertaken the printing of material film printing after its print surface of drying baker high temperature drying, and dried material film needs to reduce the modification that the material film is heated through the chill roll cooling, and chill roll rotates at a high speed with the material film, and needs logical recirculated water to keep the temperature of chill roll; Existing chill roll mechanism is because must the water flowing rotation, and chill roll requires very low rotary resistance, and conventional sealing means can not reach effect preferably, bad sealing means causes leakage easily, influence rolling bearing, influence the electrical equipment operate as normal, produce dangerous.

Summary of the invention

The purpose of this utility model provides a kind of intaglio press cooling roller device, has solved prior art and can not realize that low resistance turns round, the problem of sealing effectiveness difference.

The technical scheme that the utility model adopted is, a kind of intaglio press cooling roller device, comprise chill roll, chill roll is by bearing A, bearing B is supported on respectively among wallboard A and the wallboard B, the water inlet end of chill roll is equipped with seal receptacle B seal receptacle A and end cap successively by wallboard A outer surface, seal receptacle B, be provided with cavity C between the contact-making surface of seal receptacle A, the chill roll inner chamber is provided with water inlet pipe, be backwater channel between the interior circle of water inlet pipe and chill roll, be provided with barrier in the end cap inner chamber of end cap is divided into cavity A and cavity B, cavity A and cavity B are not equipped with return pipe B and return pipe A.

The beneficial effects of the utility model are not adopt hermetically-sealed constructions such as oil sealing, the sealing of realization cooling water, the damping of reduction chill roll; Three cavitys, two backwater structures guarantee that backwater is smooth and easy; The isolated mechanism of bearing guarantees the bearing scale erosion that is not cooled.

Fig. 1 is the structural representation of the utility model device embodiment.

Among the figure, 1. end cap, 2. cavity A, 3. throw rijng, 4. cavity B, 5. cavity C, 6. bearing A, 7. chill roll, 8. backwater channel, 9. water inlet pipe, 10. bearing B, 11. cooling water, 12. water proof grooves, 13. return pipe A, 14. return pipe B, 15. wallboard A, 16. wallboard B, 17. seal receptacle A, 18. seal receptacle B, 19. barriers.

The specific embodiment

Below in conjunction with the drawings and specific embodiments the utility model is elaborated.

As Fig. 1, the structure of the utility model intaglio press cooling roller device is, comprise chill roll 7, chill roll 7 is by bearing A6, bearing B10 is supported on respectively among wallboard A15 and the wallboard B16, the water inlet end of chill roll 7 is equipped with seal receptacle B18 successively by wallboard A15 outer surface, seal receptacle A17 and end cap 1, seal receptacle B18, be provided with cavity C5 by the axle center between the contact-making surface of seal receptacle A17, chill roll 7 inner chambers are provided with water inlet pipe 9, the cylindricality torus space that constitutes between the interior circle of water inlet pipe 9 and chill roll 7 is a backwater channel 8, the cooling water 11 that water inlet pipe 9 flows into flows out through backwater channel 8, be provided with barrier 19 in the end cap 1 inner chamber of end cap 1 is divided into cavity A2 and cavity B4, cavity A2 and cavity B4 are separately installed with return pipe B14 and return pipe A13; The termination that chill roll 7 puts in cavity A2 is a bottom cecum (passing water inlet pipe 9 in the hole) with holes, and is provided with throw rijng 3 at the termination circumferential outer surface; Chill roll 7 is provided with water proof groove 12 with the contact-making surface section surface of seal receptacle A17, seal receptacle B18, barrier 19.

Device of the present utility model supports chill roll 7 by bearing A6, bearing B10 and realizes rotating; The seal face of end cap 1 makes the inner airtight cavity that forms; Cooling water 11 enters chill roll inside by water inlet pipe 9 under the normal condition, is discharged by backwater channel 8, flows out by return pipe B14; Throw rijng 3 with the cooling water at water return outlet place get rid of to around, cavity A2, cavity B4, cavity C5 are connected by water proof groove 12 with chill roll 7, realize the less slit of spindle nose, prevent that cooling water 11 from flowing backwards by chill roll 7 spindle nose outer walls; Enter cavity B4 as cooling water 11 through chill rolls 7 spindle nose outer walls, through water proof groove 12 with water get rid of to around, and flow out by return pipe A13.

Device of the present utility model, by with water inlet, backwater, rotation, and sealing mechanism connection is installed cleverly, realized the specification requirement of single unit system, the bearing of hi-Fix realizes that chill roll rotates and the servo-actuated of material film, three cavitys of arranging continuously, isolate between cavity relatively independent, the application of throw rijng and chamber hole and the less slit of cooling roll shaft, prevent through cooling roll shaft backwater, and guarantee to rotate.Two water return outlets guarantee that backwater is smooth and easy, prevent ponding.

Device of the present utility model has been realized chill roll and the servo-actuated of material film, low resistance running; The sealing means of three cavitys does not use oil sealing and other to produce the obturator of resistances, the isolated mechanism of bearing, guarantee bearing not with the corrosion of cooling water contact preventing; Centering type backwater cavity better guarantees backwater.
