Abstract

The utility model relates to a cooling device in a high-speed aluminum foil composite printer, which comprises a drying device and a main driving traction device. A water cooling device is also arranged between the drying device and the main driving traction device; the water cooling device comprises a cooling roller arranged under an aluminum foil and an auxiliary guide roller for guiding the aluminum foil to enter into the cooling roller; the cooling roller is fixedly arranged on a stand; and a water inlet pipe and a water outlet pipe are connected to one end of the inner lateral cavity of the cooling roller through a water inlet and outlet directional part. The utility model has the advantages that the aluminum foil can be cooled down quickly and effectively; the rolling temperature is directly reduced under 50 degrees, so that the printing speed is improved to 45 to 60 m/minute; the problem of slow temperature reduction speed of the aluminum foil is solved; and the printing speed and the production capacity are improved; the problem that the performance and the printing quality of the aluminum foil are influenced due to high roll temperature is simultaneously solved; and the durability of rubber pressure rollers is ensured.

Description

Cooling device in the high speed aluminium foil complex printer

Technical field

The utility model relates to a kind of high speed aluminium foil complex printer, relates in particular to the cooling device in this machine.

Background technology

High speed aluminium foil complex printer generally is made up of frame, aluminium paper unwinding device, sizer, printing equipment, ink-feeding device, drying unit, aluminium foil air-cooling device, main transmission draw-gear, wrap-up, control system etc.

High speed aluminium foil complex printer basic functional principle is:

Aluminium foil, paper unwinding device: installation aluminium foil, paper roll unreel support simultaneously;

The gluing set composite: aluminium foil backing and paper are compound;

Printing equipment: aluminium foil and the compound good back of paper are printed on aluminium foil surface;

Ink-feeding device: for printing equipment provides printing ink and makes the printing ink circulation;

Drying unit: be the printing ink oven dry of compound glue, printing;

Aluminium foil air-cooling device: the aluminium foil that comes out in the baking oven is carried out air cooling;

Main transmission draw-gear: machine transmission, product transmission traction power;

Wrap-up: the product web-like of composite print oven dry is taken in.

As seen from Figure 1: have only the blower fan of employing style cooling processing, when the aluminium foil high speed printing of reality, only depend on air cooling not reach the requirement of cooling.The problem that exists: first, when aluminium foil by the drying tunnel about through 200 ℃ behind the printed coating, the temperature of aluminium foil is very high, it is shorter again that baking oven exports to the stroke of rolling, and the speed of a motor vehicle is fast again, temperature in the volume will reach 70～80 ℃, has a strong impact on the printing quality and the rolling quality of product, simultaneously owing to temperature in the volume is difficult for distributing the influence also certain to the performance of aluminium foil; The second, printed coating is that resin and pigment, particularly resin can stickingly join and not solidify under higher temperature through the remaining material of overbaking, it is short-tempered bright to produce coating surface after in income is rolled up, color is aging, and adhesive force reduces, and serious generation aluminium foil and coating are glued the connection problem; The 3rd, the temperature of aluminium foil is too high, is delivered on the rubber transmission pressure roller, makes the rubber rollers after-tack of being heated, and damages easily; The 4th, because the restriction of temperature intensification condition, print speed printing speed can only be controlled at 30～40 meters/minute, has influenced production capacity.Among the figure: drying unit 6, air-cooling device 7, main transmission draw-gear 9, gap bridge roller 91, wrap-up 10.

Summary of the invention

The utility model technical issues that need to address have provided the cooling device in a kind of high speed aluminium foil complex printer, are intended to solve the above problems.

In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions:

The utility model comprises: drying unit, main transmission draw-gear; Between described drying unit, main transmission draw-gear, also settle a water-cooling apparatus; Described water-cooling apparatus comprises: be placed in chill roll and an auxiliary guide roll that guides aluminium foil to enter chill roll under the aluminium foil; The chill roll fixed in position is on frame; End in the inboard chamber of chill roll connects water inlet pipe and outlet pipe by the Inlet and outlet water directional component.

Compared with prior art, the beneficial effects of the utility model are: effectively aluminium foil is carried out fast cooling, the rolling temperature directly is reduced to below 50 ℃, makes print speed printing speed bring up to 45～60 meters/minute, solve the slow problem of aluminium foil cooling, improved the speed and the production capacity of printing; Also solve simultaneously the interior temperature height of volume to aluminium foil performance and the affected problem of printing quality, guaranteed the durability of rubber roller.

The specific embodiment

Below in conjunction with the accompanying drawing and the specific embodiment the utility model is described in further detail:

By Fig. 2, Fig. 3 as seen: the utility model comprises: drying unit 6, main transmission draw-gear 9; Between described drying unit 6, main transmission draw-gear 9, also settle a water-cooling apparatus 71; Described water-cooling apparatus 71 comprises: be placed in 710 times chill rolls 711 of aluminium foil and an auxiliary guide roll 712 that guides aluminium foil to enter chill roll; Chill roll 711 fixed in position are on frame 713; End in the inboard chamber of chill roll 711 connects water inlet pipe 715 and outlet pipe 716 by Inlet and outlet water directional component 714.

In Fig. 3: frame 1, aluminium paper unwinding device 2, sizer 3, printing equipment 4, ink-feeding device 5, drying unit 6, air cooling equipment 7, water-cooling apparatus 71, main transmission draw-gear 9, gap bridge roller 91, wrap-up 10.

Operation principle of the present utility model is:

Open water valve from the beginning, make water enter recurrent state; Water leads to into pipe in the water through water inlet pipe, flows in the chill roll from the other end of chill roll, and water touches the roller wall and just has been cooled to the roll body surface, and roll surface the temperature absorption of aluminium foil, has reached the effect that aluminium foil cools off with after aluminium foil contacts again; The roller wall is delivered to water again after being drawn onto the heat of aluminium foil, and water temperature also rises thereupon, and water constantly circulates, and chill roll is remained in certain temperature range.Because water constantly enters, under the setting effect that flows to, the water nature after the heat absorption flows out from outlet, has kept the temperature of water in the roller.In order better to make aluminium foil reach cooling-down effect, disposed an auxiliary guide roll, make the contact area of aluminium foil and chill roll bigger, the big more cooling effect of contact area is just good more.Aluminium foil comes out to cool off fast through water chill rolls and auxiliary guide roll from drying tunnel, and chill roll is followed the aluminium foil synchronous rolling, reaches successional cooling.
