Mini-type reel fixing device

Abstract

The invention relates to a mini-type reel fixing device. A tensioning block is clung to each side wall of a core shaft; the outer surface of each tensioning block is arc-shaped; two ends of every two adjacent tensioning blocks are connected through tightening springs; an ejecting column guide hole is formed in each side wall of the core shaft; one end part of each ejecting column is fixed to the corresponding tensioning block, and the other end parts of the ejecting column is inserted into the corresponding ejecting column guide hole in the core shaft; a prismatic hole matched with the cross section of the core shaft in shape is formed in the axial direction of the core shaft; a left end cover is arranged at the left end part of the core shaft; a pyramidal inclined nut is connected onto an adjusting rod in a threaded manner; a right end cover is fixed onto the adjusting rod on the right side of the inclined nut; an adjusting wheel is fixed onto the adjusting rod on the right side of the right end cover; the inclined nut is inserted into the prismatic hole in the axial direction of the core shaft; the left end part of the adjusting rod is rotationally mounted onto the left end cover. The problem that the parallelogram structure cannot meet the operational requirements of a mini-type reel can be solved, and the over tightening and over loosing phenomena can be avoided.

Description

technical field [0001] The invention relates to a device for tensioning materials mainly used in the automotive electronics and mobile phone electronics industries, in particular to a miniature reel fixing device. Background technique [0002] At present, in the stamping industry, most feeders use a parallelogram tensioning mechanism to fix the coil material. For micro-coil materials, especially those with relatively brittle materials and precise positioning, this fixing mechanism cannot be satisfied. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies in the prior art, and to provide a micro-reel fixing device capable of accurately and stably tensioning materials. [0004] According to the technical solution provided by the present invention, the miniature reel fixing device includes an adjustment wheel, a right end cover, an oblique nut, an adjustment rod, a mandrel, a tension block, an ejection column, a tension spring...
