Abstract

The invention relates to a cooling roller, used to cool concave printer and feeding film of compositing machine, wherein it comprises cooling roller, support fixed on printer wall with reflux chamber and container fixed on support; the inner face has cooling roller with blade through the bearing to be positioned above the container; two sides of bearing are mounted with annular sealing fixed on cooling roller; there is a sealing device between cooling roller and support. Therefore, the face of cooling roller can rotate by itself, to obtain stable and cooling function. And the invention can reduce cooling water consumption.

Description

Cooling roller device

Technical field

The present invention relates to the cooling device that uses on a kind of intaglio press and the compounding machine, more particularly, relate to a kind of cooling roller device.

Background technology

The chill roll mechanism that uses on intaglio press, compounding machine at present is passive rotating mechanism, and as pure passive mode, the rotation of chill roll places one's entire reliance upon and expects the friction gravitation of film, and covert passive mode then need increase power transmission and speed follower.No matter be any mode, all can produce the speed difference between material film and cooling roll surface, or increase the manufacturing cost of producing, the printing finished product is caused damage.The reason that causes mainly contains two: the first, in the chill roll structure half storey water rotary inertia too big; The second, during normal use, the unstability of water increases the control difficulty, can not at the uniform velocity rotate, and in addition, the utilization of cold water is also insufficient.

Summary of the invention

The object of the present invention is to provide a kind of cooling roller device of self-rotary; make the cooling roll body have the ability or the trend of spinning; and formation stable state. this kind cooling roller device can make full use of the ability of cooling water simultaneously, takes away the heat on the printing fast, better protection printing finished product.

The objective of the invention is to be achieved through the following technical solutions: a kind of cooling roller device, comprise the cooling roll body, comprise that also one can be fixed on the support that has the backwater cavity on the printing press wall board and be fixed on liner device on the support; Inner surface is provided with the cooling roll body of blade and feels relieved, is positioned on the liner device by bearing, and the ring packing that is fixed on the cooling roll body is installed on the bearing both sides; Between cooling roll body and support, be provided with sealing device.

In such scheme, the cooling roll body comprises body of roll blade and the plug that is mounted and fixed on together.

Liner device in the scheme is welded by water inlet pipe and inner chamber body, is provided with apopore on water inlet pipe.

In order to prevent that cooling water from overflowing on the cooling roll body, described sealing device adopts labyrinth seal.

Compared with prior art, chill roll of the present invention has following beneficial effect:

1, in the process of printing, under the endogenetic process of cooling water, chill roll has possessed the ability or the trend of spinning, under the friction external force effect of material film, can carry out the speed lifting apace and walk abreast into stable state, has protected finished product to greatest extent;

2, in the cooling procedure, chill roll surface temperature ability even and cooling water is fully utilized;

3, adopt this kind structure, the consumption of cooling water is declined to a great extent, the waste of environment and water resource is reduced.

Description of drawings

Fig. 1 is the fundamental diagram of chill roll in the prior art;

Fig. 2 is the structural representation of chill roll of the present invention.

Among the figure: 1. chill roll, 2. inlet channel, 3. bearing, 4. printed matter, 5. support, 6. sealing ring, 7. bearing, 8. sealing ring, 9. plug, 10. water inlet pipe, 11. inner chamber body, the 12. cooling bodies of roll, 13. sealing ring, 14. sealing rings, 15 blades, 16. apopores, 17 apopores, 18. apopores.

The specific embodiment

Below in conjunction with drawings and Examples the present invention is described in detail, but they are not limitation of the invention.

Fig. 1 shows chill roll structure of the prior art, and chill roll 1 is installed on the wallboard through bearing 3, by swivel joint water inlet pipe 2 and chill roll 1 is connected as one.This kind structure because the unstability of water increases the control difficulty, can not at the uniform velocity be rotated, and causes expecting can producing speed difference between film and the cooling roll surface, and the printing finished product is caused damage.

By Fig. 2; the support 5 that has the backwater cavity is fixed on the wallboard through screw; the liner device that is made of water inlet pipe 10 inner chamber body 11 is fixed on the support 5 through mating holes; feel relieved, be positioned on the liner device by bearing 7 by the cooling roll body that the plug 9 cooling bodies of roll 12 constitute; on the bearing both sides the 6.8 pairs of bearings of annular sealing ring that are fixed on the cooling roll body are installed and protect, labyrinth seal 13.14 is fixed on support and the cooling roll body through screw.

After chill roll 1 feedwater, the cooling roll body has had the ability and the trend of spinning, at 4kg/cm ²Under the water pressure, can make the spinning of chill roll body.In the process of printing, under the endogenetic process of cooling water, under the friction external force effect of material film, can carry out speed apace and promote.Because the cooling water layer is in the body state of having one's bosom filled with all the time at the outer interlayer of the inner bag and the cooling body of roll,, the skin of chill roll also is in a kind of stable status all the time so rotating.Cooling water makes the outer humidity of cooling roll body even, and flows fast, takes away the heat that is imported into by skin.Because inner bag is limited with the outer interlayer space of cooling roll body,, the waste of environment and water resource is reduced so the consumption of cooling water also declines to a great extent.

Press the structure shown in the accompanying drawing 2, press water enters from the water inlet of left end, delivery port 16 through diagram water inlet pipe 10 overflows, under pressure, water flows out to two ends along the outer wall of diagram inner chamber body 11, at this moment the effect of water that is under pressure of the left and right vane sheets 15 in the diagram cooling roll body 12, had spinfunction or trend, after flowing out from blade 15, concentrate to the concentrated water cavity of diagram support 5 in current through inner chamber body 11 and 9 delivery ports of opening 17 of diagram plug, and through 18 outflows, recycling afterwards.Under normal duty, the surface of the diagram cooling body of roll 12 is with the speed rotation of 300m/min, cooling water can not be excessive on the roll body surface, therefore cool off 12 of the bodies of roll at figure support 5 and diagram, diagram 13,14 labyrinth seal structures have been designed, avoided the contact seal element, the rotational resistance of the cooling body of roll 12 is reduced as far as possible.Bearing 7 supports, the location with illustrating between the cooling roll bodies that illustrate 10,11 inner bags that constitute and 9.12 formations, and with the ring packing structure that illustrates 6,8 bearing is protected.
