Abstract

The invention relates to a drawing device for melt-spun staple fibers and belongs to the technical field of staple fiber drawing equipment. The drawing device comprises a water bath tank, a support, alifting platform, a water bath tank observation port cover plate and an observation port cover plate drive mechanism and is characterized in that a left drawing roller mechanism is correspondingly arranged at the left end of a water bath tank cavity, and a right drawing roller mechanism is correspondingly arranged at the right end of the water bath tank cavity; the lifting platform is correspondingly arranged above the water bath tank and connected to the support, a water bath tank observation port is arranged in the middle of the length direction of the lifting platform, the water bath tankobservation port cover plate is correspondingly arranged above the water bath tank observation port and provided with a cover plate rotary shaft on the rear side, the left end and the right end of thecover plate rotary shaft are supported on the lifting platform, the observation port cover plate drive mechanism is arranged on the lifting platform and connected with the right end of the cover plate rotary shaft, the left drawing roller mechanism is arranged at the left end of the lifting platform, and the right drawing roller mechanism is arranged at the right end of the lifting platform. Thedrawing device has the advantages that safety is guaranteed, an operator can favorably observe conditions such as the liquid level of the water bath tank according to needs, and a good drawing effecton tows is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of short fiber drawing equipment, in particular to a melt spinning short fiber drawing device. Background technique [0002] In the short fiber drawing process, the upper open water bath (also called "hot bath" in the industry, the same below) is located between the front and rear drafting devices, such as the invention patent publication number CN105780160B (a short fiber drawing production line The drawing water bath above), its function is to heat the tow above the glass transition temperature for drawing. [0003] In the published Chinese patent documents, in addition to CN105780160B mentioned above, there are also "a drafting water bath on a short fiber drawing production line" provided by CN106367825B, "water bath" recommended by CN20237855U, and "a kind of water bath" introduced by CN103682469A. "Water Bath" and "Water Bath" disclosed by CN205329226U, etc. [0004] Since the common feature of the wa...
