Diversification BCF spinning machine

Technical field

The present invention relates to one and can either produce terylene PET, the diversification BCF spinning machine of nylon PA and polypropylene fibre PP can be produced again, belong to BCF spinning machine and manufacture field.

Background technology

Publication number CN202072825U, title: a kind of terylene BCF continuous spinning machine, comprise raw material drying device, device for suction material, metering device, batch mixing bucket, screw extruder, dinyl kettle, the micropore of spray silk becomes trilobal or becomes the spinnerets of Y shape, cross air blowing device, spinning shaft, stretcher strain coiler device; Stretcher strain coiler device comprises the one-level stretching device be made up of a feeding hot-rolling and two to three drawing-off hot-rollings, it is characterized in that raw material drying device is made up of the feed hopper be connected to each other by feeding pipe, crystallizing bed, drying chamber, storaging bucket, crystallizing bed with conveying be connected with the hot-air duct discharging hot-air, blower fan, air heater, pulse blower fan hot-air duct be equipped with successively, drying chamber lower end is connected with an air inlet pipe, air inlet pipe is equipped with dehumidifier and air heater, drying chamber upper end is connected with a blast pipe; Batch mixing bucket communicates with a nitrogen device or nitrogen cylinder; The screw rod leading portion of screw extruder is the mixing refining head being shaped with numerous wire nail.Its weak point is: this equipment can only spin terylene BCF, and can not be used for nylon and polypropylene spinning use, purposes is single, and limitation is large.

Summary of the invention

Purpose of design: in order to solve the problem in background technology, design one can either spin terylene PET, can be used in again the diversification BCF spinning machine of nylon and polypropylene spinning.

Design: in order to realize above-mentioned purpose of design.1, the draw roll pair one of terylene BCF continuous spinning machine and draw roll pair two inner homogeneous are equipped with heating wire, and the temperature of draw roll pair one is 70 DEG C ~ 90 DEG C, and the temperature of draw roll pair two is 120 DEG C ~ 180 DEG C; Draw roll pair one is 3.8 ~ 4.2 with the drafting multiple of input roller; Draw roll pair two is the design of 2.7 ~ 3.3 with the drafting multiple of input roller, is technical characteristics of the present invention.The object done like this is: when producing terylene PET, wet section carries out drying through drying device, blending bunker batch mixing, Screw Extrusion, manifold spinning, spinnerets spray silk are carried out in dried section, adjust the velocity ratio of network input roller and draw roll pair one simultaneously, make the drafting multiple of draw roll pair one be 3.8 ~ 4.2; The temperature of adjustment draw roll pair one and draw roll pair two, the temperature of draw roll pair one is made to be 70 DEG C ~ 90 DEG C, the temperature of draw roll pair two is 120 DEG C ~ 140 DEG C, enters winder winding winding forming after using draw roll pair one and draw roll pair two pairs of terylene PET to carry out secondary drawing-off simultaneously.When producing nylon, section does not need to enter drying device drying, blending bunker batch mixing, Screw Extrusion, manifold spinning, spinnerets spray silk is entered after directly entering metering device by device for suction material, adjust the velocity ratio of network input roller and draw roll pair two simultaneously, make the drafting multiple of draw roll pair two be 2.7 ~ 3.0; The temperature of adjustment draw roll pair two, makes the temperature of draw roll pair two be 150 DEG C ~ 180 DEG C, enters winder winding winding forming after using draw roll pair two pairs of terylene PET to carry out a drawing-off simultaneously.When producing polypropylene fibre, section does not need to enter drying device drying, blending bunker batch mixing, Screw Extrusion, manifold spinning, spinnerets spray silk is entered after directly entering metering device by device for suction material, adjust the velocity ratio of network input roller and draw roll pair two simultaneously, make the drafting multiple of draw roll pair two be 2.7 ~ 3.0; The temperature of adjustment draw roll pair two, makes the temperature of draw roll pair two be 150 DEG C ~ 180 DEG C, enters winder winding winding forming after using draw roll pair two pairs of terylene PET to carry out a drawing-off simultaneously.Thus, can by regulating the drafting multiple of draw roll pair one and draw roll pair two, regulate the temperature of draw roll pair one and draw roll pair, be adapted to the spinning requirement of different terylene PET, nylon PA and polypropylene fibre PP material, thus realize a terylene BCF continuous spinning machine and can spin terylene PET, nylon PA and polypropylene fibre PP tri-kinds of materials, a tractor serves several purposes, when, limits throughput more in kind, decrease the cost payout of procuring equipment, greatly save production cost and production site.

Technical scheme: a kind of diversification BCF spinning machine, comprise terylene BCF continuous spinning machine, draw roll pair one and draw roll pair two inner homogeneous of described terylene BCF continuous spinning machine are equipped with heating wire, and the temperature of draw roll pair one is 70 DEG C ~ 90 DEG C, and the temperature of draw roll pair two is 120 DEG C ~ 180 DEG C; Draw roll pair one is 3.8 ~ 4.2 with the drafting multiple of input roller; Draw roll pair two is 2.7 ~ 3.3 with the drafting multiple of input roller.

The present invention is compared with background technology, on the basis of background technology, add counter extensioin pair roller one and the control of draw roll pair two in temperature and drafting multiple, make terylene BCF continuous spinning machine achieve the function of a device fabrication three kinds of material yarns, greatly saved production cost.
