Description

Negative pressure type automatic recovery machine for combed noil

Technical Field

The invention relates to the technical field of spinning equipment, in particular to a negative pressure type automatic recovery machine for combed noil.

Background

Spinning is a process of processing textile fibers into yarns, yarns for high-grade products need to be subjected to a combing process, and are called combed yarns, and the process comprises a plurality of processing steps of blowing, carding, pre-drawing, lap winding, combing, head drawing, two drawing, three drawing, roving, spinning, post-processing and the like. The noil content of the noil in the noil of an A201 combing machine is less than 65 percent, the noil content of the noil of the combing machines such as E7/5 and E7/6 of Switzerland company, domestic PX-2, FA266 and the like is even more than 70 percent, and the noil can be spun fiber.

Taking A201E type combing machine as an example, after the combing noil of the combing machine is wound on the dust cage to a certain thickness, the noil is torn off from the dust cage by a worker and is put into a cotton returning vehicle to pack and pack for recycling, the labor intensity of the worker is increased by the way of recovering the noil, and the noil which is wound too much and too tight cannot be torn off from the dust cage, so that the stand capability of the worker is influenced, and the normal operation of the combing machine is also hindered to a certain extent. If a composite round cage dust removal unit is used, such as a GYFL-III type unit, the rotary compressor is easy to damage the noil fibers, and the quality and effect of recycling are influenced.

In the chinese patent application No. 201610378317.8 entitled "a device for picking noil for a circular carding machine", a device for picking noil from a carding drum (cage of dust, but the noil still needs to be collected manually after it has fallen on a resting plate 11) is disclosed.
