Description

Technical Field

[0001] This utility model relates to a winding and rewinding tool, specifically a single-section material storage arm. Background Technology

[0002] In the processing and production of steel strip slitting machines, the slitting steel strip needs to be coiled, packaged, and loaded and unloaded by I-beams. Traditionally, after winding, the I-beams need to be transported to the unwinding equipment to be unloaded, and then the steel coil is removed from the I-beams. The I-beams are then transported to the winding equipment. This process is cumbersome and affects the efficiency of operation. Summary of the Invention

[0003] This utility model provides a simple structure that can store and transport materials online or offline, efficiently and conveniently complete the uncoiling of steel coils, and a single-line storage arm mounted on an I-beam reel.

[0004] The technical solution adopted by this utility model is: a single-line storage arm, characterized in that: it includes a base, a support seat is mounted at the center of the base, a rotating shaft is vertically supported by bearings inside the support seat, the lower end of the rotating shaft extends into the base and is connected to a large drive gear via a key, a planetary reducer is also supported and mounted on the base, a drive motor is connected to the planetary reducer, the output shaft of the planetary reducer extends into the base and is connected to a small drive gear via a key, the small drive gear meshes with the large drive gear, the upper end of the support seat supports a rotating seat via bearings, the rotating seat is connected to a rotating shaft extending out of the upper end of the support seat via a key, two horizontal arm assemblies are respectively connected to the left and right sides of the rotating seat facing outwards, the horizontal arm assemblies include two vertical wall plates and two arcs The plate and positioning cover consist of two vertical wall plates connected parallel to each other on the outside of the rotating seat. The two vertical wall plates are opposite each other and connected to two arc plates facing outwards. Buffer strips are provided on the upper and lower edges of the vertical wall plates. An arc-shaped notch with an arc angle of less than 180 degrees is provided on the inner side of each of the two vertical wall plates. The inner wall of the arc-shaped notch on the inner side of the two vertical wall plates is provided with the same internal tapered thread structure. The positioning cover includes a cover plate and a tapered thread screw section. The tapered thread screw section is vertically connected to the center of the inner side of the cover plate. The tapered thread screw section is screwed into the thread structure of the two vertical wall plates. The inner side of the cover plate abuts against the outer end of the vertical wall plate. The circumference of the cover plate is equal to the circumference of the central spindle tube of the I-beam wheel fitted on the horizontal arm assembly.

[0005] The base is provided with multiple lifting holes evenly distributed around the outer perimeter of the support.

[0006] The rotating seat is supported by an outer ring bearing and an inner ring bearing, respectively.

[0007] The inner ring bearing is a tapered roller bearing, and the outer ring bearing is a ball bearing.

[0008] The outer ring of the ball bearing is fixedly connected to the rotating seat by screws, and the inner ring of the ball bearing is fixedly connected to the support seat by screws.

[0009] The beneficial effects of this utility model are:

[0010] 1. After the steel strip is wound around the I-beam reel, when unloading, align the horizontal boom assembly with the central mandrel tube of the I-beam reel, push the I-beam reel, and the two vertical wall plates of the horizontal boom assembly will pass through the central mandrel tube of the I-beam reel and support the I-beam reel. Combined with the arc plate outside the vertical wall plate, the stability of the connection and support can be improved, preventing the I-beam reel from rotating or swaying when it passes through the horizontal boom assembly, thus completing the online unloading operation of the I-beam reel.

[0011] 2. When transportation is required, the positioning cover is inserted and screwed into the threaded structure on the inner side of the two vertical wall plates through the tapered thread screw section. While tightening, the cover plate can effectively prevent the I-beam wheel from slipping off the horizontal arm assembly and improve transportation safety. When it is necessary to unwind the steel coil, the side plate on the outside of the I-beam wheel is removed and the steel coil wound on the central mandrel tube is unwound. The cover plate can prevent the central mandrel from moving, improving the convenience and safety of unwinding the steel coil.

[0012] 3. Horizontal arm assemblies are set on opposite sides of the rotating seat, which can meet the needs of online loading of I-beams on one side and online unwinding of steel strip on the other side, thereby improving the efficiency of steel strip slitting production.

[0013] 4. The planetary reducer drive effectively ensures stable drive during transportation and online operation. Attached Figure Description
