Therefore, the technical effect of having a heating function is achieved, and the composite steel roller replaces a driving roller to stretch and level the cylindrical film under the heating traction.
Description
Technical Field
The utility model relates to a driving roller on inflation film manufacturing machine, concretely relates to compound steel roller.
Background
The phenomenon of non-uniform thickness often can appear in the inflation film manufacturing process in the inflation film manufacturing machine, lead to the production of some folds, produce the phenomenon of high injustice during the influence rolling, because it is the plastics material to be the fashioned film of inflation film manufacturing, its cooling air and the gaseous inhomogeneous of inflation film manufacturing in process of production all can lead to its thickness uneven, the cylindric film after the inflation film manufacturing can be through the driving roller transmission, the effect of conduction can only be played to original driving roller single structure, can't solve above-mentioned problem.
Disclosure of Invention
In order to solve the above problems, an object of the present invention is to provide a composite steel roller with heating function, which replaces a driving roller to make a cylindrical film stretch and level under heating and traction through the composite steel roller.
In order to achieve the above purpose, the utility model provides a following technical scheme: the composite steel roller comprises a roller body, wherein the roller body is a hollow pipe, left and right end covers are fixedly arranged at two ends of the roller body, a roller shaft is respectively arranged on the outer end faces of the left and right end covers, heat-conducting liquid is filled in the roller body, a central hole is formed in the left and right end covers, the two sides of a heating pipe are respectively arranged in the central holes formed in the left and right end covers, and the heating pipe is electrically connected with a temperature controller.
The heating pipe is positioned on the outer wall of the inner cavity of the roller body, and a plurality of discs which are arranged in sequence are arranged on the outer wall of the inner cavity of the roller body.
And a bearing and a sealing structure are arranged between the heating pipe and the inner walls of the central holes of the left end cover and the right end cover.
The sealing structure comprises annular grooves formed in the inner walls of central holes of the left end cover and the right end cover, and sealing sleeves sleeved on the outer wall of the heating pipe are arranged in the annular grooves.
The sealing sleeve comprises a steel sleeve, a rubber sleeve and a cotton isolating ring.
The utility model discloses a this kind of structure, when the fashioned cylindric film of blown film is through this compound steel roller, can heat the cylindric film, can pull the cylindric film after its heating when the rolling is pull simultaneously and detach the fold, make it level and more balanced, make the cylindric film obtain the effect of once more drawing simultaneously, improve the utilization ratio of material and reduce the cost of production, just so reached the technological effect who possesses the heating function.
The invention is further described with reference to the accompanying drawings and the detailed description.
Drawings
Fig. 1 is a schematic structural diagram of an embodiment of the present invention.
Detailed Description
The present invention is described in detail below with reference to the following examples, which are only used for further illustration of the present invention, and should not be construed as limiting the scope of the present invention.
As shown in fig. 1, the embodiment discloses a composite steel roller, which includes a roller body 1, the roller body 1 is a hollow tube, two ends of the roller body 1 are fixedly provided with a left end cover 2 and a right end cover 2, outer end surfaces of the left end cover 2 and the right end cover 2 are respectively provided with a roller shaft 21, the roller body 1 is filled with a heat-conducting liquid 3, the heat-conducting liquid 3 is oil or water, the left end cover 2 and the right end cover 2 are provided with a central hole 22, two sides of a heating pipe 4 are respectively arranged in the central holes 22 of the left end cover 2 and the right end cover.
A plurality of disks 41 which are arranged in sequence are arranged on the outer wall of the heating pipe 4 which is positioned in the inner cavity of the roller body 1. Such a structure can improve the contact surface with the heat-conducting liquid 3, so that the heat-conducting liquid 3 can be heated more quickly.
A bearing 5 and a seal structure 6 are disposed between the heating pipe 4 and the inner walls of the center holes 22 of the left and right end caps 2. Through the structure, the stability of the heating pipe 4 can be always ensured in the rotating process of the composite steel roller, so that the composite steel roller can not rotate along with the roller body 1, and the outer end of the heating pipe 4 is fixedly connected with a frame of a film blowing machine, so that the stability of the heating pipe 4 in the working process is ensured.
The sealing structure 6 comprises an annular groove arranged on the inner wall of the central hole 22 of the left end cover 2 and the right end cover 2, and a sealing sleeve sleeved on the outer wall of the heating pipe 4 is arranged in the annular groove. The heat-conducting liquid 3 can not overflow through the structure, and the stability and the reliability of the heat-conducting liquid in operation are ensured.
The sealing sleeve comprises a steel sleeve, a rubber sleeve and a cotton separating ring, wherein the steel sleeve, the rubber sleeve and the cotton separating ring are sequentially arranged from inside to outside. Thus, the components can make the sealing and insulating effect better, and further improve the stability in operation.
By adopting the technical scheme, when the cylindrical film formed by film blowing passes through the composite steel roller, the cylindrical film can be heated, and the heated cylindrical film can be stretched to remove wrinkles when being wound and pulled, so that the cylindrical film is more smooth and balanced, the cylindrical film is stretched again, the utilization rate of materials is improved, the production cost is reduced, and the technical effect of heating is achieved.
In the work, should need two compound steel rollers cooperative work, the cylindric film advances to convey in the clearance of two compound steel roller pressfitting for cylindric film both sides all can wait to heat, and the heating is that the temperature can be controlled between 150 ℃ to 250 ℃ under the control of temperature controller, through under the traction rolling of wind-up roll, makes it tensile under the heating state, and is more level and more smooth.
