Self-adjusting opening device

Abstract

The invention relates to a mechanical loosening device, in particular to a self-adjusting loosening device which comprises a loosening cabin, a loosening drum, an air inlet pipe, and a rotating power element which drives the loosening drum to rotate, wherein the loosening cabin of a truncated cone shape, includes a feed hopper arranged at the top end of the loosening cabin and a discharge port installed on the right wall of the loosening cabin; the air inlet pipe is communicated with the left wall of the loosening cabin, and the loosening drum is rotatably connected in the loosening cabin; the loosening drum includes a fast cutting mechanism, a loosening mechanism, a rotating shaft and an inner blocking cylinder which is arranged in the loosening drum; a drum wall of the loosening drum and the inner blocking cylinder are both fixed on the rotating shaft which is rotatably connected on the loosening cabin and connected with the rotating power element, and the drum wall is divided into a feed part of a coniform shape and a discharge part of a truncated cone shape. In order to solve the problem of winding fibers on the loosening drum, the self-adjusting loosening device aims to provide the self-adjusting loosening device capable of avoiding fiber winding.

Description

technical field

[0001] The invention relates to a mechanical opening device, in particular to a self-adjusting opening device. Background technique

[0002] Raw cotton, wool, chemical staple fiber and cotton, linen, polyester, rags, etc. are mostly transported in the form of fiber blocks pressed into bales. Before processing the fiber block, it is necessary to loosen the fiber block. The sound insulation cotton used in automobiles is also transported in bundles, and the fiber blocks need to be loosened before use. The subsequent steps also involve adding additives such as grease and plastic particles to the loosened fiber blocks. things.

[0003] The majority of existing fiber blocks are loosened by an opener, and the opening steps of a conventional opener include two steps of tearing and loosening. Shredding is the tearing and loosening of fiber blocks. Loosening is the use of blades, fins, brads or needle teeth to strike the fed fiber block and simultaneously penetrate...
