Cover causes to be seriously worn to sealing surface；In addition sealing element is rotary seal structure, and abrasion is further exacerbated by after dynamic contact,
Therefore the rotary seal structure is frequently necessary to maintenance, replacement.Existing rotary seal structure is set on cylinder, and maintenance is inconvenient.
Summary of the invention
The technical problem to be solved by the utility model is to provide a kind of rotations of three backhaul drying rollers easy to maintain
Sealing structure.
In order to solve the above-mentioned technical problem, the technical solution of the utility model is: a kind of rotation of three backhaul drying rollers
Sealing structure, be arranged between cylinder and feed inlet or discharge port, the rotary seal structure include: be fixed on feed inlet or
Fixed frame on person's discharge port is fixed on swivel mount on cylinder and with cylinder rotation, is formed in flat on fixed frame
The seal chamber that row extends in the axial direction of cylinder, the sealing element being fixed on swivel mount, the sealing element are set to seal chamber
It is interior；The swivel mount is composed of two semicircle rings, and the sealing element is composed of two semicircle ring portions.
Preferably, labyrinth seal is formed between the fixed frame and the swivel mount, the seal chamber is two or more, institute
Sealing element is stated to be arranged corresponding to the seal chamber.
Preferably, the end of each semicircle ring is respectively formed folding ear, is fixedly connected between two neighboring folding ear.
Preferably, boss is set on the cylinder, and the side wall of the boss and the side wall away from sealing element of swivel mount support
It leans on.
Preferably, it is provided with convex block corresponding with the boss on the swivel mount, insertion hole is offered on the convex block,
Screw is arranged in described insert in the hole, and the screw is set with the rotation of boss screw thread.
Preferably, the insertion hole is long hole.
Due to the adoption of the above technical solution, the utility model has the advantage that swivel mount using two semicircle rings
It is composed, if necessary to being safeguarded, being replaced to sealing element, it is only necessary to it first unscrews bolt and makes two semicircle ring separation,
Screw is unscrewed again removes semicircle ring one by one, it is very convenient without being dismounted to cylinder, work is greatly saved
When.
Detailed description of the invention
Fig. 1 is three backhaul drying roller schematic device in the prior art；
Fig. 2 be the utility model proposes rotary seal structure schematic diagram；

Specific embodiment
The above objects, features, and advantages of the utility model in order to facilitate understanding, are illustrated below with reference to embodiment.It answers
Understand, these embodiments are merely to illustrate the utility model rather than limitation the scope of the utility model.For these implementations
A variety of modifications of example will be apparent to those skilled in the art, the general principles defined herein,
It can be achieved in other embodiments without departing from the spirit or scope of the present utility model.
The rotary seal structure of three backhaul drying roller of one kind shown in Figure 2, setting in cylinder 5 and feed inlet 1 or
Between person's discharge port 2, which includes: the fixed frame 6 being fixed on feed inlet 1 or discharge port 2, is fixed on cylinder
Swivel mount 7 that is on body 5 and being rotated with cylinder 5；The axial direction that cylinder 5 is formed in parallel on the fixed frame 6 extends
Seal chamber 61,62, be fixed with sealing element 71,72 on the swivel mount 7, the sealing element 71,72 is set to seal chamber 61,62
Within.Labyrinth seal is formed between the fixed frame 6 and swivel mount 7, therefore the seal chamber 61,62 is two or more, sealing
Part 71,72 is arranged corresponding to the seal chamber 61,62.And sealing element 71,72 can be releasably arranged with the swivel mount 7, just
In being safeguarded and replaced.
Referring to Fig. 3, the swivel mount 7 is not an entire circular ring structure, but combined by two semicircle rings 7a, 7b and
