Abstract

The invention relates to an acid feeder for a viscose fiber spinning machine and belongs to the technical field of viscose fiber production equipment. Vertical acid-feeding main pipes and vertical right-angled acid-feeding main pipes are arranged at equal intervals and added on the basis of two vertical acid-feeding main pipes at the head and tail of an acid trough; the main pipes are connected with a centrifugal distributing container; the centrifugal distribution container is communicated with an acid feeding and distributing pipe in which an acid feeding and distributing baffle is provided. Therefore, uniformity of acid feeding for acid bath is greatly improved, uniformity of acid feeding speed is guaranteed, air content of the whole acid feeder, especially of the acid trough, is decreased, smooth forming of yarns is ensured, and late drawing quality of the yarns is guaranteed.

Description

technical field [0001] The invention relates to an acid feeding device, more specifically, the invention relates to an acid feeding device for a viscose fiber spinning machine, which belongs to the technical field of viscose fiber production equipment. Background technique [0002] Acid bath is an important part of viscose fiber spinning. The viscose fiber spinning machine is to input the qualified viscose liquid prepared in the previous process into the viscose pipe from the two interfaces of the front and rear of the car, and then from the acid bath The small holes in the spinneret are sprayed out in the form of thin streams, which immediately produce chemical reactions and solidify into tows, and then guide the tows to the spinning disk through the guide wire hooks for proper drafting, and then each spinning The tows generated at the position are bundled by the guide wire horns above the spinning disk and then led to the rear of the car. When leaving the car tail, the fiv...
