Description

Technical Field

[0001] The utility model relates to the field of steel strip corrugated pipe production equipment, in particular to a steel strip unwinding device for producing steel strip corrugated pipes. Background Art

[0002] Steel belt corrugated pipe generally refers to HDPE steel belt reinforced spiral corrugated pipe, which is usually composed of high-density polyethylene material and steel belt reinforced structure. Compared with traditional metal pipes, HDPE steel belt reinforced spiral corrugated pipe is light in weight and easy to install. It can be laid quickly and reduce construction costs. When producing steel belt corrugated pipe, it is necessary to use a steel belt unwinding device to unwind the steel belt roll.

[0003] The diameter of the fixing mechanism of the existing steel strip unwinding device is relatively fixed, which makes it difficult to adapt to steel strip coils of various specifications. At the same time, after the steel strip coil is unwound, the empty roller needs to be removed and then the steel strip coil needs to be installed. The installation of the steel strip coil takes a certain amount of time, during which the machine needs to be stopped for operation, resulting in low processing efficiency. Utility Model Content

[0020] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

[0021] Reference Figure 1 and Figure 2 As shown, a steel strip unwinding device for producing steel strip corrugated pipes comprises a base 1, a turntable 2 is rotatably connected to the upper end of the base 1, a symmetrically arranged support plate 3 is fixedly connected to the upper end of the turntable 2, a turntable 4 is rotatably connected to the outer center of the support plate 3, a fixed cylinder 5 is fixedly connected to the outer side of the turntable 4, a first rotating shaft 6 is rotatably connected to the outer center of the turntable 4, the other end of the first rotating shaft 6 passes through the inner cavity of the fixed cylinder 5 and is fixedly connected to a handle 14, a first bevel gear 7 is fixedly connected to the outer surface of the first rotating shaft 6, four second bevel gears 8 equidistantly distributed are meshed on the periphery of the first bevel gear 7, a second rotating shaft 9 passing through the inner cavity of the fixed cylinder 5 is fixedly connected to the end of the second bevel gear 8, and a screw is fixedly connected to the end of the second rotating shaft 9 away from the second bevel gear 8. A threaded rod 10, the other end of the threaded rod 10 is threadedly connected with a threaded sleeve 11, an arc-shaped clamping plate 12 is fixedly connected to the outside of the threaded sleeve 11, a telescopic rod 13 is fixedly connected between the arc-shaped clamping plate 12 and the fixed tube 5, and the first rotating shaft 6 can be driven to rotate by turning the handle 14, and the rotation of the first rotating shaft 6 will drive the first bevel gear 7 to rotate. With the rotation of the first bevel gear 7, the four second bevel gears 8 will rotate synchronously, so that the four second rotating shafts 9 drive the four threaded rods 10 to rotate, and the threaded sleeve 11 will slide along the surface of the threaded rod 10. At this time, the telescopic rod 13 plays a guiding and limiting role on the clamping plate 12, and the four clamping plates 12 will approach or move away from each other under the drive of the threaded sleeve 11, so that steel strip coils of different specifications can be fixed.

[0022] A first motor 15 for driving the turntable 4 to rotate is fixedly installed on the inner side of the support plate 3. When the device is working normally, the mechanism on the support plate 3 on one side is used for unwinding operations, and the staff installs the steel strip roll on the mechanism on the support plate 3 on the other side. When the steel strip roll is unwound, the first motor 15 will drive the turntable 2 to rotate one hundred and eighty degrees, thereby moving the installed steel strip roll to the processing area.

[0023] Two symmetrically arranged brackets 16 are fixedly connected to the upper edge of the turntable 2, and a third rotating shaft 17 is rotatably connected between the two brackets 16. A rotating plate 18 is fixedly connected to the outer surface of the third rotating shaft 17. The lower end of the rotating plate 18 is in contact with the upper end of the support plate 3. Two electric push rods 19 are fixedly installed on the front side of the rotating plate 18. The output end of the electric push rod 19 is fixedly connected to a vertically arranged limit rod 20. The limit rod 20 can limit the steel strip roll to prevent the steel strip roll from deviating during the unwinding process.

[0024] Working principle: When the device is in use, the steel strip roll is first sleeved on the surface of the clamping plate 12 on one side, and then the handle 14 is turned to drive the first rotating shaft 6 and the first bevel gear 7 to rotate. As the first bevel gear 7 rotates, the four second bevel gears 8 will rotate synchronously, so that the four second rotating shafts 9 drive the four threaded rods 10 to rotate. At this time, the threaded sleeve 11 will slide along the surface of the threaded rod 10, thereby causing the clamping plate 12 to move outward to clamp the steel strip roll, and then the rotating plate 18 is rotated to make it fit on the upper end of the support plate 3, and the limit rod 20 is pulled by the electric push rod 19 to make it fit on the surface of the steel strip roll to limit the steel strip roll. After that, the turntable 4 is driven to rotate by the first motor 15 to unwind the steel strip roll. When the steel strip roll is unwinding, the staff can install a new steel strip roll on the clamping plate 12 on the other side. When the existing steel strip roll is unrolled, the turntable 2 is driven by the second motor 21 to rotate 180 degrees to move the new steel strip roll to the working area.
