Summary of the invention
Technical problem to be solved in the utility model provides a kind of membrane coiler structure of film chartered plane, can reduce the working strength of wearing around plastic film.For this reason, the utility model is by the following technical solutions: it comprises the first roller group of stationkeeping and is contained in the second roller group on the tressel, the roller of the first roller group is parallel with the cylinder of the second roller group, the roller of the second roller group is arranged and the roller arrangement submission mispairing of the first roller group is closed, described tressel liftable or swing, roller in the second roller group has the film of wearing position with tressel lifting or swing and around the film position, when wearing the film position, roller in the described second roller group is in outside the first roller group one side up, around the film position time, the roller in the described second roller group is in outside the first roller group one side down.Owing to adopt the technical solution of the utility model, when wearing around plastic film, only need film is placed on the first roller group, then with the decline of the roller in the second roller group or to lower swing, make roller in the second roller group pass roller gap in the first roller group, automatically plastic film is formed between the roller of the roller of the first roller group and the second roller group and wear, can greatly make things convenient for wearing of plastic film around work around state, shorten and wear, raise labour efficiency around work-hours.
The specific embodiment
With reference to accompanying drawing.The utility model comprises the first roller group 1 of stationkeeping, and in the present embodiment, the described first roller group 1 is installed on fixed mount 10, and fixed mount is installed on the seat board 7.
The utility model also comprises the second roller group 2 that is contained on the tressel, described tressel liftable or swing, and in the present embodiment, described tressel is a swing span 20, so more saves space and energy simplified structure, in addition, described tressel also can be a crane.
As shown in the figure, the roller of the first roller group is parallel with the cylinder of the second roller group; The roller of the second roller group is arranged and the roller arrangement of the first roller group is interlaced cooperation, the roller that also is the second roller group 2 is when moving with tressel, first roller passes first roller of the first roller group 1 and the space between second roller, and second roller passes second roller of the first roller group 1 and the space between the 3rd roller ... n roller passes n roller of the first roller group 1 and the space between n+1 roller.
Roller in the second roller group 2 has the film of wearing position with tressel liftable or swing and around the film position, in Fig. 1 and 4, the roller in the second roller group 2 is in around the film position, and in Fig. 3, the roller in the second roller group 2 is in wears the film position.
As shown in Figure 3, when wearing the film position, the roller in the described second roller group 2 is in outside the first roller group 1 one side up; As shown in figs. 1 and 4, around the film position time, the roller in the described second roller group is in outside the first roller group one side down.
In the present embodiment, described tressel is a swing span, and described swing span drives swing by cylinder 3, and described swing span connects connecting rod 4, and described connecting rod connects cylinder.Described swing span comprises left side swing wallboard 21 and right swing wallboard 22, cylinder lever connecting rod 23 between left side swing wallboard and the right swing wallboard, left side swing wallboard 21 is connected with connecting rod 4, the oscillating axle 5 of swing span is contained in the bearing 50, the bearing 50 on the left side is contained in the connecting rod 4, the bearing 50 on the right is contained on the bearing seat 6, and the bearing seat 6 on the right is contained on the seat board 7 on the right, on the seat board 7 on the right of the two ends of oscillating axle also are connected in and the seat board 7 on the left side.
What the roller that described swing span is provided with the arrangement mode and the first roller group arranged that the submission mispairing closes is the arc cantilever group 24 in the center of circle with axis of oscillation A, and the roller of described second tin roller group is installed on the arc cantilever.Described arc cantilever extends in the downside of left side swing wallboard 21 and right swing wallboard 22.
Described staggered cooperation also promptly also is that swing span is when being swung by air cylinder driven, the arc cantilever that first roller of the second roller group 2 is installed passes first roller of the first roller group 1 and the space between second roller, and the arc cantilever that second roller of the second roller group 2 be installed passes second roller of the first roller group 1 and the space between the 3rd roller ... the arc cantilever that n roller of the second roller group 2 be installed passes n roller of the first roller group 1 and the space between n+1 roller.
Arc cantilever in the described arc cantilever group, long more away from its length of axis of oscillation more.Like this, can be with less pendulum angle, realize plastic film wear around.
