Description
Technical field
The utility model is related to woven bag process equipment field, more particularly to a kind of film conveying roller.
Background technology
Often reprocessed using waste and old bag in the production processes such as woven bag such as bag of cement, process is successively by waste and old bag
Broken, granulation, high temperature are made film, water-cooled, are cut into strip and braiding.During section by film with waveform wearing alternatively up and down
Crossing multiple parallel two-by-two and turning to contrary conveying roller, tension force is transmitted and film is set up by conveying roller, then will by slicer
Film in motion process is cut into slices along its length.As conveying roller is transmitted in thin-film process due to film therein
The reason such as power inequality or conveying roller bounce, membrane tension failure easily occur has film pendency phenomenon to occur between two rollers, and
Membrane tension is excessive, easily causes film breaks.
Utility model content
In view of this, the purpose of this utility model is to provide a kind of film conveying roller, can adjust conveying roller as needed
External diameter, to keep membrane tension effective.
The utility model is solved the above problems by following technological means：A kind of film conveying roller, including base sleeve, adjusts spiral shell
Bar and gas cell, are provided with the cone being slidably connected with base sleeve in the base sleeve, be circumferentially evenly arranged with polylith arc outside base sleeve
Plate, the arc by through base sleeve side wall and the connecting rod that be connected with base sleeve side walls and cone wall contacts, arc
Spring being provided between base sleeve outer wall, being connected by air bag layer between arc, described adjusting screw rod one end is connected with cone,
The other end is passed outside base sleeve vertically and is threadedly coupled with base sleeve, and the gas cell is connected with air bag layer.
Further, the connecting rod is provided with the cambered surface that mates with cone with one end of cone contact.
The beneficial effects of the utility model：Film conveying roller of the present utility model, including base sleeve, adjusting screw rod and inflation
Capsule, is provided with the cone being slidably connected with base sleeve in the base sleeve, be circumferentially evenly arranged with polylith arc, the arc outside base sleeve
Shape plate is by through base sleeve side wall and the connecting rod that be connected with base sleeve side walls and cone wall contacts, arc and base sleeve outer wall
Between be provided with spring, connected by air bag layer between arc, described adjusting screw rod one end is connected with cone, and the other end is along axle
To passing outside base sleeve and being threadedly coupled with base sleeve, the gas cell is connected with air bag layer.The film conveying roller of the structure, can basis
The external diameter for adjusting conveying roller is needed, to keep membrane tension effective.
Description of the drawings
With reference to the accompanying drawings and examples the utility model is further described.
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the structural representation that arc is connected with air bag layer.
Specific embodiment
The utility model is described in detail below with reference to accompanying drawing, as shown in Figure 1-2：A kind of film conveying roller, bag
Base sleeve 1, adjusting screw rod 2 and gas cell 3 is included, the cone 4 being slidably connected with base sleeve in the base sleeve, is provided with, circumferential equal outside base sleeve
Even be provided with polylith arc 5, the arc by the connecting rod 6 that be connected through base sleeve side wall and with base sleeve side walls with bore
Body wall contacts, are provided with spring 7 between arc and base sleeve outer wall, connected by air bag layer 8, the regulation between arc
Screw rod one end is connected with cone, and it is outer and be threadedly coupled with base sleeve that the other end passes base sleeve vertically, the gas cell and air bag layer
Connection, spring hold arc all the time in tension state, it is to avoid arc is slipped from base sleeve, arc and air bag layer
Round is surrounded, the conveying roller outer ring structure of conveying film is constituted, in conveying thin-film process, film is contacted with conveying roller outer ring, when
When needing the diameter for adjusting outer ring, on the one hand, rotate adjusting screw rod, band movable cone is moved, and promotes arc outside by cone
Expansion is drawn in, on the other hand, after arc moves to correct position, is filled toward in air bag layer by gas cell proper amount of
Gas, makes air bag layer be expanded into suitable shape, to make conveying roller outer ring substantially into cylindrical shape, you can film is carried out defeated
Send.In sum, the film conveying roller of the structure, can adjust the external diameter of conveying roller as needed, to keep membrane tension to have
Effect.
Used as the further improvement of above-mentioned technical proposal, the connecting rod is provided with one end of cone contact and is mated with cone
Cambered surface.It is easy to cone preferably to promote connecting rod and arc together to move.
Finally illustrate, above example is only unrestricted in order to the technical solution of the utility model to be described, although ginseng
The utility model is described in detail according to preferred embodiment, it will be understood by those within the art that, can be to this
The technical scheme of utility model is modified or equivalent, the objective and model without deviating from technical solutions of the utility model
Enclose, which all should be covered in the middle of right of the present utility model.
