Abstract
The invention discloses a drying device which comprises a support (1) and a drying cylinder (2) arranged on the support (1). A coating is arranged on the surface of the drying cylinder (2), two rails (3) are arranged at the upper end and the lower end of the drying cylinder (2) respectively, two sliding strips (4) sliding along the rails (3) are arranged on the rails (3), the sliding strips (4) are fixed to the rails (3) through fixing blocks (5), and an elastic coating (6) is connected between the two sliding strips (4). Through the mode, the telescopic elastic coating is used in the drying device, the width of the drying device is adjusted to be equal to that of a wet paper web, and therefore the problem of yellow edges is eliminated. The drying device has the advantages of being simple in operation, high in efficiency, convenient to use and the like.
Description
Technical field
The present invention relates to the paper making equipment field, particularly relate to a kind of drying unit.
Background technology
In paper-making process, wet web need carry out drying by dryer surface.Dryer surface is coated with coating, and the width of wet web is less than the width of coating usually.Because the vapours of drying cylinder inside is equally distributed, therefore, when there is no wet web through drying cylinder, the temperature of dryer surface is consistent.When wet web is dry by dryer surface, moisture high temperature evaporation in wet web, because the moisture evaporation needs to absorb heat, therefore have the coating surface temperature of wet web process to reduce, so cause not having the drying cylinder coating surface temperature of wet web process higher than the drying cylinder coating surface that the wet web process is arranged.And, after the temperature of drying cylinder coating is higher than a certain critical-temperature, the coating of drying cylinder both sides has the coating layer portion of wet web process with respect to centre, than being easier to sclerosis, " yellow limit " problem of the drying cylinder coating that namely paper industry is commonly called as.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of drying unit, by using telescopic elastic coating, regulates its width and equates with wet web, thereby eliminate " yellow limit " problem, have simple to operate, efficiency is high, the advantage such as easy to use.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: a kind of drying unit is provided, comprise: support, be arranged on the drying cylinder on described support, the surface of described drying cylinder is provided with coating, the two ends up and down of described drying cylinder are provided with two tracks, described track is provided with two draw runners that slide along track, and described draw runner is fixed in orbit by fixed block, between described two draw runners, is connected with an elastic coating.
In a preferred embodiment of the present invention, described two tracks are parallel to each other.
In a preferred embodiment of the present invention, described two draw runners are parallel to each other.
In a preferred embodiment of the present invention, on described each draw runner, the quantity of fixed block is two.
The invention has the beneficial effects as follows: drying unit of the present invention, by using telescopic elastic coating, is regulated its width and is equated with wet web, thus elimination " yellow limit " problem, have simple to operate, efficiency is high, the advantage such as easy to use.
The accompanying drawing explanation
In order to be illustrated more clearly in the technical scheme in the embodiment of the present invention, in below describing embodiment, the accompanying drawing of required use is briefly described, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain other accompanying drawing according to these accompanying drawings, wherein:
Fig. 1 is the structural representation of a kind of drying unit one preferred embodiment of the present invention;
In accompanying drawing, the mark of each parts is as follows: 1, support, 2, drying cylinder, 3, track, 4, draw runner, 5, fixed block, 6, elastic coating.
The specific embodiment
Below will the technical scheme in the embodiment of the present invention be clearly and completely described, obviously, described embodiment is only a part of embodiment of the present invention, rather than whole embodiment.Embodiment based in the present invention, those of ordinary skills, not making all other embodiment that obtain under the creative work prerequisite, belong to the scope of protection of the invention.
Refer to Fig. 1, the embodiment of the present invention comprises:
A kind of drying unit, comprise: support 1, be arranged on the drying cylinder 2 on described support 1, the surface of described drying cylinder 2 is provided with coating, the two ends up and down of described drying cylinder 2 are provided with two tracks 3, described track 3 is provided with two draw runners 4 that slide along track 3, described draw runner 4 is fixed on track 3 by fixed block 5, between described two draw runners 4, is connected with an elastic coating 6.
Described two tracks 3 are parallel to each other, are convenient to draw runner 4 and slide.
Described two draw runners 4 are parallel to each other.
On described each draw runner 4, the quantity of fixed block 5 is two, good fixing effect.
The beneficial effect of drying unit of the present invention is:
By using telescopic elastic coating, regulate its width and equate with wet web, thereby eliminate " yellow limit " problem, have simple to operate, efficiency is high, the advantage such as easy to use.
The foregoing is only embodiments of the invention; not thereby limit the scope of the claims of the present invention; every equivalent structure or conversion of equivalent flow process that utilizes description of the present invention to do; or directly or indirectly be used in other relevant technical field, all in like manner be included in scope of patent protection of the present invention.
