Abstract

The utility model relates to a cooling roll mechanism, which is suitable for various high-speed running precise printers and capable of keeping at a low rotational inertia level. The cooling roll mechanism comprises a cooling roller barrel, a water return box and a water inlet pipe, and is characterized in that a drain hole is arranged at the outer circle of the cooling roll barrel, the water return box covers the drain hole of the cooling roll barrel rightly, and a water partition groove is arranged in the water return box. The cooling roll mechanism has the advantages that firstly, flexibility and the stability in running of a cooling roll can be improved evidently; secondly, water in the cooling roll can be drained in time so that severe rust of the inside of the cooling roll due to long-term immergence can be avoided and the service life of the cooling roll can be prolonged; and thirdly, water return is fast, and cooling efficiency is higher.

Description

A kind of chill roll mechanism

Technical field

The utility model relates to a kind of chill roll mechanism, especially a kind of chill roll mechanism that is applicable to all kinds of accurate printing machines that run up.

Background technology

At present, as shown in Figure 2 in packing and print field, cooling is often adopted individual layer, is relied on the tap water pressure water inlet by an end with a water inlet pipe on the various high speed intaglio press, and water is by the axle center backwater, with a kind of like this structure of the purpose that reaches heat radiation then.But there is the problem of two maximums in the chill roll of this structure: the one, because will arriving the pact of roll body, water inlet could flow out naturally from the exit in an end axle center after half; Whole like this roll body is laid particular stress on; Rotary inertia is very big when causing the machine operation, the easy stretcher strain of material; The 2nd, machine is poor stability when high-speed cruising, causes tension fluctuation, influence printing chromatography precision.

The utility model content

The utility model provides a kind of being applied in to run up accurate printing machine and can remain on the chill roll mechanism of low rotor inertia level.

The utility model is achieved in that a kind of chill roll mechanism; Comprise chill roll roller, recovery tank, water inlet pipe, it is characterized in that said chill roll roller cylindrical place is provided with osculum; Said recovery tank just covers on the position of roller osculum, and in recovery tank, is provided with the water proof groove.

Be provided with sealing ring and water dumping wheel between said recovery tank and the chill roll.

Compared with prior art; The utility model one is the flexibility and the operating stability that can improve chill roll significantly; The 2nd, owing to can be in time the water of the inside be drained, so the inside can not produce serious corrosion because of not soaking for a long time, so also can prolong the life-span of chill roll; The 3rd, backwater is fast, so the efficient of cooling is higher.

Description of drawings

Below in conjunction with accompanying drawing and embodiment the utility model is further specified.

Fig. 1 is the utility model structural representation.

Fig. 2 is the traditional chill roll sketch map of prior art.

Wherein 1. chill roll rollers among the figure, 2. recovery tank, 3. sealing ring, 4. bearing, 5. water dumping wheel, 6. water inlet pipe.

The specific embodiment

With reference to Fig. 1,

Please refer to shown in Figure 1ly, the utility model is made up of chill roll roller 1, recovery tank 2, sealing ring 3, bearing 4, water dumping wheel 5, water inlet pipe 6 etc.; Water inlet pipe 6 connects running water, and return pipe enters trench.When work, running water gets into roller 1 by water inlet pipe 6, and number row aperture is arranged on the water inlet pipe 6; Water is fountain shape and is mapped to roller 1 inwall, takes away the heat of outside, then rapid irising out the mouth of a river and be thrown out of from the roller; Get into recovery tank 2, enter trench from discharge outlet at last.For overcoming the defective that said mechanism exists, the utility model provides a kind of new frame mode: end water pipe water inlet, with bringing out water; But delivery port no longer is the place, axle center; But the circle hole of evenly arranging at roll body cylindrical place, the water of coming in can in time be discharged roll body, and the inside can not stockpile the water of half roller; Whole roller is balance basically, and rotary inertia significantly reduces.The roller of new construction can be eliminated traditional roller and lay particular stress on and bring the problems referred to above, obviously improves the flexibility and the operation stability of roller.To completely soak formula refluxes to change into directly and refluxes from bottommost.The backwater route is the shortest like this, and the time is the fastest, and the inside ponding is minimum.This moment, whole roller compared balance, and rotary inertia reduces greatly.

Fig. 2 is traditional chill roll structure diagram.When work, running water gets into roller by water inlet pipe, and number row aperture is arranged on the water inlet pipe; Water is fountain shape and is mapped to the roller inwall; Take away the heat of outside, fall into the interior bottom of roller then and wait for that water level rises to the spill-over of axis hole position and comes out to get into recovery tank, enter trench from discharge outlet at last.Through Fig. 1 and Fig. 2 are compared and can see: Fig. 2 roller inside is the water that about half roller is housed forever, and integral body lays particular stress on.And the inner water of Fig. 1 roller can be drained rapidly, only remaining a spot of water, and therefore integral body is balance basically.

Claims

1. a chill roll mechanism comprises chill roll roller, recovery tank, water inlet pipe, it is characterized in that, said chill roll roller cylindrical place is provided with osculum, and said recovery tank just covers on the position of roller osculum, and in recovery tank, is provided with the water proof groove.

2. chill roll as claimed in claim 1 mechanism is characterized in that, is provided with sealing ring and water dumping wheel between said recovery tank and the chill roll.
