Chemical fiber spinning box and application method thereof

Abstract

The invention provides a chemical fiber spinning box and an application method thereof. The chemical fiber spinning box comprises a support frame; a support plate fixedly mounted in the support frame;a heating box fixedly mounted at the top of the support plate; a push plate arranged in the heating box in a slidable and hermetic manner; a pushing mechanism mounted on the support frame and connected with the push plate; a plurality of yarn discharge pipes linearly arranged in the heating box; a plurality of cooling coils respectively positioned below the plurality of yarn discharge pipes; a liquid outgoing pipe connected with one ends of the cooling coils; and a liquid incoming pipe connected with the other ends of the cooling coils. The chemical fiber spinning box and the application method thereof have the advantages of good convenience of use, low cost and good setting effect.

Description

technical field [0001] The invention relates to the technical field of fiber manufacturing, in particular to a chemical fiber spinning box and a method for using the same. Background technique [0002] The spinning box is one of the main parts of the melt spinning machine. After the polymer melt passes through the filter, it enters the spinning box, and is spun by each spinning position after melt distribution and heat preservation. [0003] Most of the traditional chemical fiber spinning boxes are extruded by hydraulic pressure, which requires a hydraulic system, and the cost of the hydraulic system on the market is relatively high, and the hydraulic system will explode during the operation process, which is easy to damage the equipment. cause harm to operators; at the same time, most of the existing chemical fiber limiters are vertically output, which leads to the fact that the collection mechanism can only be set vertically, which cannot meet the needs of the horizontal c...

Problems solved by technology

[0003] Most of the traditional chemical fiber spinning boxes are extruded by hydraulic pressure, which leads to the need for a hydraulic system. The cost of the hydraulic system on the market is relatively high, and the hydraulic system will explode during the operation of the cylinder, which is easy to damage the equipment. cause harm to operators; at the same time, most of the existing chemical fiber limiters are vertically output, which leads to the fact that the collection mechanism can only be set vertically, which cannot meet the needs of the horizontal collection device; in addition, the traditional spinning box Most of the time, wind blowing is used to cool and shape the molten chemical fiber raw materials. Since the direction of the wind blowing cannot be accurately controlled, it is easy to cause quality problems in the shaped fibers.
