Description

The printing machine heated roller

Technical field

The utility model relates to a kind of cylinders of printing press, refers to a kind of printing machine heated roller that better effect can be provided especially.

Background technology

Printing is a kind of with direct or indirect method, with the processing procedure of image or literal massive duplication, belongs to and produces service industry, also is a manufacturing ring.Though printing and papermaking, gunpowder, and the compass pin is listed as Ancient Chinese for four inventions, but really develop is in quattrocento Germany inventor paddy Rustenburg invention metal typography, and adopt out wooden letterpress, this vertical spin formula hand is pulled printing machine, continued to use 300 years though it is simple in structure, to 18th century art of printing almost passed and the whole world, become the important civilized pillar of modern society, each advanced country all pays much attention to its development, it is considered as the spirit and the construction emphasis of material progress, and through printing product processed like the shadow following the person especially be accompanied by modern's life of every day.

Because, modern printed matter is more and more polynary in the use, traditional two dimensional surface printing is difficult to meet masses to the requirement on the visual experience, liked by the consumer so have printing one release of stereo concave-convex pattern, in the industry cycle constantly positive research and development are following and have many dependency structures to get permission patent, for example: the heating arrangement of No. 320115 automatic valley printing machine of Taiwan patent announcement is an exemplary, it mainly is the surface that heatable electrothermal layer and thermal insulation layer that can thermal insulation are made inner and contiguous this pinch roller of pinch roller that is located at printing machine in the lump, and at the transmission of electricity dish of one of pinch roller end installing one sustainable supply electrothermal layer electric energy, the template high temperature that electrothermal layer not only can be provided be close to outside the pinch roller surface is provided the printed matter of concave convex texture with impression, and can serious relative friction and compressing not take place with template, and can increase its service life and tool durability; On the other hand again with heat insulation by thermal insulation layer, make pinch roller not heat Fu of reason electrothermal layer lead and form the condition of high temperature, dark tool security.

But set electrothermal layer there is no the good detection facility in its pinch roller of said structure, so temperature is just controlled difficult, it is because a power line is respectively gone into by the roller two ends by power supply system, temperature control need be installed in inside, added heat affecting and made the malfunctioning and damage of controller easily, and inner electrothermal layer also only is distributed in one-sided, so the heating inequality causes the roller heating surface because of the thermal expansion bending easily, cause the enormous pressure that needs by between two rollers just can finish printed matter, often cause the machine abrasion, be the shortcoming of its maximum.

The utility model content

The purpose of this utility model is, design can be carried out the zone and heats, and can realize accurate temperature control, makes whole bowl temperature keep uniform printing machine heated roller.

For reaching aforementioned purpose, technical solution adopted in the utility model is, a kind of printing machine heated roller comprises a cylinder, its inner hollow, and cylinder be provided with the elongated slot breach with in communicate; The cylinder inboard is provided with heating plate, and described heating plate has more than two, its outer insulating barrier that is covered with; Also comprise two above sensing rod for temperature, be embedded and on cylinder, correspond respectively to aforementioned heating plate; One control circuit is equipped on cylinder axle head one side, in it and be provided with adapter and electric wire and link to each other with aforementioned heating plate and sensing rod for temperature.

The utility model can carry out the zone with two above heating plates heats, and cooperates the accurate temperature control of control circuit by sensing rod for temperature, thus whole bowl temperature is kept evenly, thus reach effect preferably.

The specific embodiment

Shown in Fig. 1～5, the set a kind of printing machine heated roller of the utility model, it mainly includes: a cylinder 1, its inner 15 hollows, and cylinder 1 be provided with elongated slot breach 17 with in communicate;

Heating plate

13,14, its surface is covered with insulating barrier, and they distribute all over being located at cylinder 1 inboard;

3 sensing rod for temperature 11 are embedded and correspond respectively to

aforementioned heating plate

13 and 14 on cylinders 1; And

One control circuit 2 is equipped on cylinder 1 axle head one side, in it and be provided with adapter 16 and electric wire 12 and link to each other with

aforementioned heating plate

13,14 and sensing rod for temperature 11.

During enforcement, this adapter 16 adopt mercury contacts or carbon brush contact all can, in addition, configuration can be provided with two elongated slot breach 17 on its cylinder 1, and cylinder 1 is separated into a big block 18 of an arc and an arc block of cells 19 for convenience; Among the

figure heating plate

13,14 totally two branches be set as small one and large one, be attached at the inboard of the large and

small block

18,19 of cylinder 1 with correspondence; Heating plate 13 also can be set as multi-disc, and what distribute according to demand for heat; The inside 15 of this cylinder 1 hollow can be used to fill out and is provided with heat insulation foam again,

heating plate

13,14 can be adjacent to be difficult for falling to take off; And this sensing rod for temperature 11 also is provided with three, or establishes more as four or six according to the increase and decrease of cylinder 1 length, to be embedded respectively in the default hole 10 on cylinder 1 large and

small block

18,19.

By this, shown in the 1st～5 figure, its cylinder 1 not only can two

heating plates

13,14 carry out the zone heats, and can be respectively by its corresponding sensing rod for temperature 11, cooperate control circuit 2 and obtain temperature control accurately, temperature can keep even when whole cylinder 1 was moved, its design is gone up because block of cells 19 inboards also are provided with the heating plate 14 of small pieces, so can overcome the shortcoming of existing monolithic heating plate, its big block is heated to be one-sided expansion and extends when causing bending, utilize the block of cells heating to make and expand and extend temperature controllable change elongation, make roller keep minimum deflection, the best thermal effect that adds is provided, and because the required power supply of whole combination transmit by mercury formula adapter 16, so but its control circuit 2 also dragline be located at the side of cylinder 1 and away from the thermal treatment zone, rotate with cylinder 1 and increase heat dissipation starting heel, avoiding high temperature to cause damage, thereby prolong its service life.

Above-mentioned specific embodiment is purpose, feature and the effect that is used for describing in detail the utility model; for the personage who is familiar with this type of skill; according to the above description; may do partly change and modification to this specific embodiment; its essence does not detach the spiritual category person of the utility model, all should be included in the utility model protection domain.
