Closed multifunctional reducing wrapper

Abstract

The invention provides a closed multifunctional reducing wrapper. The closed multifunctional reducing wrapper comprises a supporting base, wherein a large bent hook is connected with the supporting base through a rotating shaft; the large bent hook is provided with an upper pressing arm and a lower pressing arm; the lower pressing arm is connected with a pressing cylinder; the lower pressing arm is connected with the upper pressing arm through an amplification mechanism; wrapping adhesive tape devices are arranged in the large bent hook, the upper pressing arm and the lower pressing arm and two-wheel tension mechanisms and adhesive tape error correction mechanisms are arranged in the wrapping adhesive tape devices; one end of a beam position cylinder is connected with the rotating shaft through a crank, and the other end of the beam position cylinder is connected with a beam position cylinder support; and the pressing cylinder, the amplification mechanism, the tension adjustment cylinders in the two-wheel tension mechanisms and the adhesive tape error correction mechanisms are in a double-side symmetric distribution. The closed multifunctional reducing wrapper can be conveniently applicable for working situations of different winding drum diameters after being adjusted simply; due to the stacking of the upper pressing arm and the lower pressing arm, a 360-degree wrap angle of a wrapping adhesive tape on a winding drum can be realized, so the wrapping forces of the winding drums having different diameters cannot be influenced; therefore, slipping of the closed multifunctional reducing wrapper due to an undersized wrap angle during wrapping of the wrapping drums having smaller diameters can be avoided; and the appearance of a tape volume can be guaranteed.

Description

technical field [0001] The invention relates to a coiling aid used for coiling of metallurgical plates, in particular to a closed multifunctional variable-diameter coiling aid. Background technique [0002] High-grade sheets used for home appliances, vehicles, and precision equipment have high requirements on the flatness of the surface of the sheet. Clamping with jaws and coiling for the first few turns will easily cause creases and dents. There will always be a few meters of waste for each roll of strips that cannot be used. Therefore, For steel plate or non-ferrous metal materials with a thickness of less than 1mm, use tape to help roll. The existing coiling aid has blank gaps in its feed inlet, and its functions are not comprehensive. It is applicable to a single coil diameter and is only suitable for one specification variety with a diameter of 508mm. Since the position of the reel is fixed, it is difficult to develop a reeling aid suitable for multiple diameters, for ...

AI Technical Summary

Problems solved by technology

For example, the adjustment of the spatial position of the roll-assisting device, the difficulty in adjusting the tension of the roll-assisting belt when reels with different diameters, and the change of the wrapping angle of the rolling-assisting tape

[0003] like Figure 7 Among them, the existing rolling aids cannot realize the 360° sealing of the tape wrap angle, and it is easy to slip when rolling the material, and the appearance quality of the rolling material is difficult to guarantee

When the diameter of the coiled coil reaches the predetermined value, the coil is easy to be unpacked

Moreover, the existing coiling aid has a self-weight of more than two tons. In the standby position, the cantilever crossbeam swinging upward will bear a huge bending distance, and frequent reciprocating twists will cause fatigue damage to the components, which poses a danger to the safety of operators and machinery.
