Embodiment Construction

[0012] The specific implementation manner of the present invention will be further described below in conjunction with the accompanying drawings.

[0013] A kind of expansion and contraction reel mechanism, see attached Figure 1-Figure 4 , which is characterized in that: it includes a main shaft 2, an expansion and contraction reel 4, a spring device 16 and an expansion and contraction transmission mechanism; there are at least three slide grooves 18 on the outer circumference of the main shaft; the expansion and contraction reel 4 is composed of at least three It is composed of two separate reels that are independent of each other, and are set on the outside of the main shaft 2. Each reel has the same central angle and radius, and the inner side of the reel is provided with a connecting seat 7, and each reel can expand with each other. The shrinking block 5 moves radially; the expansion and contraction transmission mechanism includes an expansion and contraction power device...

Abstract

A collapsible reel mechanism comprises a main shaft, a collapsible reel, a spring device and a collapsible transmission mechanism, wherein the collapsible reel is composed of at least three mutually independent separation reels. The collapsible transmission mechanism comprises a collapsible power device, a connecting rod and a plurality of wedged slide block mechanisms, each of the wedged slide block mechanisms comprises a collapsible block, a wedged block and a pulling rod, the collapsible block and the wedged block respectively have wedged oblique surfaces and form oblique surface cooperation through the wedged oblique surfaces, and the wedged block drives the collapsible block to move in a radical direction and drives the reel to synchronously open or close in order to realize extension uncoiling of a steel band coil by the collapsible reel. The collapsible reel mechanism has the advantages of flexible motion, large uncoiling force, adjustable opening degree (the working diameter) of the collapsible reel, stable and reliable working, simple adjustment and use, easy production manufacturing, high reliability and strong applicability, and is widely suitable for being arranged on various uncoilers to carry out steel band coil uncoiling in order to meet sections steel production needs.

Description

technical field [0001] The invention relates to a steel strip uncoiler equipment, in particular to an expansion and contraction reel mechanism. Background technique [0002] The steel strip uncoiler is an indispensable and important equipment for section steel production. It is used to support the steel strip and unwind the steel strip coil. The core part of the uncoiler is the expansion and contraction reel device, which directly affects the technical performance of the uncoiler. Due to the limitation of structural design, the expanding and shrinking reel of the existing uncoiler has problems such as small expansion and contraction radius, insufficient stretching force, and low mechanism action sensitivity, which affects the effect of expansion and contraction uncoiling. Therefore, it is necessary to develop a new type of expansion and contraction reel device to improve the technical performance of the uncoiler. Contents of the invention [0003] The purpose of the prese...
