AI Technical Summary

Technical Problem

Existing winding devices tend to unwind cold-rolled strip steel when winding it, resulting in loose winding that fails to meet usage requirements.

Method used

It adopts a combination structure of main bevel gear and side bevel gear. The main bevel gear is driven to rotate by the crank handle, which simultaneously drives the side bevel gear and the lead screw to move the rod, fixing the inner side of the paper tube. The rotating frame is driven by the motor to rotate and fix the side plate. Combined with the design of pressure roller and spring, the cold-rolled strip steel is pressed to reduce springback.

Benefits of technology

It enables convenient installation and disassembly of paper tubes of different lengths and diameters, improves the tightness and stability of cold-rolled strip winding, and avoids the problem of excessive winding gap.

Abstract

This utility model discloses a winding device for producing strapping, including a fixed side plate and a main bevel gear. A limit ring is installed around the periphery of the fixed side plate. The main bevel gear is installed in the center of the fixed side plate, and a side bevel gear is installed on the right side of the main bevel gear. A lead screw is installed on one side of the side bevel gear, and a moving rod is threadedly connected to the periphery of the lead screw. Compared with existing winding devices, this winding device for producing strapping winds cold-rolled steel strip onto a paper tube. A motor drives a rotating frame on the base to rotate, thereby rotating the fixed side plate. The paper tube rotates with the fixed side plate, winding the cold-rolled steel strip onto the paper tube, facilitating the guidance of the cold-rolled steel strip to the center. During winding, the outer sides of the cold-rolled steel strip are squeezed by pressure rollers, reducing the rebound of the cold-rolled steel strip and preventing a large winding gap. As the steel coil expands, the pressure roller slides on a slide bar to change position, and a spring constantly pushes the pressure roller to press against the cold-rolled steel strip.
