Abstract
The invention relates to a spinning machine, which can produce two kinds of mirlon at the same time, belonging to the designing and producing technological area for the spinning machine of synthetic fiber. Because the prior spinning machine only has a heat medium furnace and polyamide 66 and 6 have different melting point and spinning temperature, one kind of production can be produced and if two kinds of production want to be produced at the same time they are carried out at two spinning machines. There is a pair of pneumatic diaphragm regulating valves on the heat medium pipe with inner spinning box in the invention and temperature detecting probe is set at the middle of melting pipe. Because regulating valve and detecting probe is added in the invention the regulating performance for side heat medium temperature is realized. After the temperature value is detected by the probe, it can be transmitted to control cell. Then the open degree of pneumatic diaphragm regulating valve is controlled by control center so as to satisfy the temperature of the side melting pipe and spinning box. The structure on the other side is immovable so that two kinds of production can be produced at the one spinning machine. The usage ratio of equipment is improved. It is suitable for small enterprise with the requirement of small batch and multi-item. The investment of equipment and the cost of production are decreased.
Description
Technical field
The invention belongs to the design and the manufacturing technology field of synthetic fiber spinning machine.
Background technology
In the production of polyamide fiber, because the fusing point of polyamide 66 and polyamide 6 is different, and difference is bigger, is respectively 253 ℃ and 215 ℃ at present.Their spinning temperature is respectively 290 ℃ and 270 ℃.And existing spinning machine only is equipped with a heating agent boiler.By the heating agent boiler material in the melt pipe is implemented heat tracing, produce.Because the fusing point of two kinds of raw materials is all different with spinning temperature, so want to produce simultaneously this two kinds of fibers, just must carry out on two spinning machines.So, be the small lot that satisfies market for some small-sized production units, the requirement of many kinds just can only increase manufacturing facilities.Cause utilization rate of equipment and installations to reduce, strengthen the raising of equipment investment and production cost.Therefore say that existing synthetic fiber spinning machine is not very desirable in design.Also do not have at present in synthetic fiber are produced, to use with the spinning machine of same structure of the present invention.
Summary of the invention
The purpose of this invention is to provide a kind of spinning machine that under a heating agent boiler situation, can produce two kinds of polyamide fibers simultaneously, to solve the practical problem that existing equipment exists in the use.
Structure of the present invention is as shown in drawings: be made of the screw extruder of both sides, the spinning manifold more than two and heating agent boiler of outfit.Specifically be equipped spinning manifold in screw extruder bottom, both sides, be connected by melt pipe between screw extruder and the spinning manifold.In the spinning manifold bottom heating agent boiler is arranged, the heating agent boiler is connected with extrusion machine head and melt pipe and spinning manifold respectively by the heating agent pipeline.On the heating agent pipeline under the inboard spinning manifold, have one group of pneumatic diaphragm control valve.On this side melt pipeline middle part, have temperature detecting probe.Heating agent pipeline under outside spinning manifold and melt pipe reach is constant.Method of work of the present invention is substantially the same with existing spinning machine method of work.Raw materials for production enter screw extruder by drying tower, and after melt extruding, melt enters spinning manifold by melt pipe and carries out spinning.Its feature is because have pneumatic diaphragm control valve on the heating agent pipeline under inboard spinning manifold and the melt pipe, has temperature detecting probe at the melt pipe middle part.This probe is used for surveying temperature in the inboard melt pipe.After recording temperature value, pass the signal to control centre's this temperature conditioning unit of standing, is according to sending output signal by temperature conditioning unit with the difference of detected temperature value and technique initialization comparison, control the opening degree of the pneumatic diaphragm control valve on the affiliated heating agent pipeline of this side melt pipe, regulate the needs temperature that satisfies this side institute producd fibers with this.As at the inboard part producing daiamid-6 fiber of spinning machine.Because the polyamide 6 spinning temperature is 270 ℃, the mitogenetic product polyamide 66 product in the outside portion, and the polyamide 66 spinning temperature is 290 ℃.Thereby then need work in the temperature control detector probe on the inboard part melt pipe, the temperature value that detects is passed to this temperature conditioning unit of control centre, temperature conditioning unit sends output signal again, by control centre's control pneumatic diaphragm control valve control opening degree, make heat enter melt pipe in right amount, reach till 270 ℃ of requirements.Thereby carry out daiamid-6 fiber production.The Outboard Sections of spinning machine is then directly come this side melt pipe is incubated through the heating agent pipeline by the heating agent boiler, produces the polyamide 66 fiber.Structure of the present invention is simple especially, just installs one group of pneumatic diaphragm control valve additional on the heating agent pipeline under the spinning machine one side spinning manifold, has temperature detecting probe on this side melt pipeline.Be connected with control system respectively again, just can on a spinning machine that is equipped with a heating agent boiler, produce the synthetic fiber of two kinds simultaneously.So just can improve usage ratio of equipment.Reach the purpose of Flexible Production.
