Embodiment
For making the purpose, technical solutions and advantages of the present invention clearer, embodiment of the present invention is described further in detail below in conjunction with accompanying drawing.
Referring to Fig. 1 to Fig. 5, the embodiment of the invention provides a kind of manufacture method of light suction transfusion hose, this method is that polyurethane film 1 is sticked to tubular pipe 2 internal surfaces that formed by high strength synthetic fibre 3 and monofilament polyester 4 braidings, specifically may further comprise the steps:
Step 101: the polyurethane of polyurethane adhesive and oven dry is passed through extruder 8 and extruder 7 respectively, be transported in the combined mould 9;
In actual applications, can choose polyurethane and polyurethane adhesive, and polyurethane adhesive is put in the material storing box 6 according to usage requirement; Polyurethane put in the dehumidifier 5 dry, bake out temperature is controlled at 80～100 ℃, and drying time is 2-4 hour, and the polyurethane after polyurethane adhesive and the oven dry enters respectively in extruder 8 and the extruder 7; Extruder 8 and extruder 7 all adopt motor speed-regulating control, and synchronous operation; The consumption of polyurethane adhesive can be controlled by the screw speed and the packaging film feeding speed of regulating extruder 8, and the consumption of polyurethane can be controlled by the screw speed of regulating extruder 7; The machine barrel of extruder 7 and extruder 8 adopts the control of electric heating temperature, and the barrel zone temperature of extruder 7 and extruder 8 is controlled at 160-200 ℃, and polyurethane and polyurethane adhesive are fused into the curtain coating shape, and enters combined mould 9 through extruder 7 and extruder 8;
Step 102: polyurethane adhesive and polyurethane continue heating in combined mould 9, and typing forms polyurethane film in combined mould 9;
In actual applications, combined mould 9 can adopt outer heating form to heat, and the polyurethane of its inside and polyurethane adhesive is continued heating be the curtain coating shape; Adding heat setting in combined mould 9 after, polyurethane forms the internal layer of polyurethane film; Polyurethane adhesive is coated in the thin polyurethane film outer surface by combined mould 9 under the pressure of extruder 8, form the skin of polyurethane film; Under the effect of die orifice extruding, the inside and outside layer of the polyurethane film of molten is fused together, and forms polyurethane film;
Step 103: the polyurethane film of moulding is carried out cooling and shaping, and coil by curler 14;
The polyurethane film of moulding carries out cooling and shaping through water bath 10 and dehydration blower fan 11 successively, and by traction belt 12 and take off roll 13 traction countings, is coiled by curler 14; Traction belt 12, take off roll 13 and curler 14 all adopt motor speed-regulating control, and synchronous operation;
Step 104: high strength synthetic fibre and monofilament polyester are woven into the tubular pipe;
The warp shaft of high strength such as terylene, polypropylene fibre synthetic fiber is placed on the denting frame, draws the magnetic eye of warp thread from the denting frame is manual, passes by fabric and arranges and pass technology, penetrate circular loom 17 stop over sheets, heald and reed successively, finishes the work of passing; According to the product technological requirement, with double weft form put into every shuttle with single latitude form or monofilament polyester weft yarn axle and dacron thread weft yarn axle monofilament polyester weft yarn axle, monofilament polyester of drawing from the weft yarn axle and dacron thread penetrate respectively in the shuttle pin, finish the weft yarn preparatory process; Warp thread and weft yarn are worn knot put into circular loom 17 die orifices together, warp thread forms shed open by certain lifting rule under the drive of heald frame and heald, and is woven into required tubular pipe with weft yarn;
Step 105: polyurethane film 16 is inserted in the tubular pipe 18, and finishes by take-up reel 20 and to batch;
Step 106: according to the length of product requirement and sulfuration platform 21, with the tubular pipe 18 of interior cover polyurethane film 16 cut into need length after, place it on the sulfuration platform 21 to handle and make finished product by sulfuration process;
At first, pour pressurized air in the tubular pipe 18 on being placed on sulfuration platform 21, it is identical with tubular pipe 18 that polyurethane film 16 is expanded, and duration of ventilation checked whether polyurethane film 16 has gas leak phenomenon about 3 minutes; Then by pipe valve 22, sulfuration steam head 23 with suppress 24 and feed water vapour, vapor tension is about 0.2 ± 0.02Mpa, under the vapor tension effect, the polyester filament and the monofilament polyester close adhesion of polyurethane film 16 and tubular pipe 18 internal surfaces, pressure hold time is about 15-20 minute; In concrete production practices, pressurized air, water vapour and cold water are all by pipe valve 22, sulfuration steam head 23 with suppress 24 and enter in the tubular pipe 18;
Step 107: behind supercooled water cooling, check and counting, dish is got packing with finished product.
In actual applications, by adjusting polyurethane film extrusion process hauling speed and plastic squeeze speed, can realize the difference of the thickness of polyurethane film outer layer glue, and then guarantee the adhesion strength of polyurethane film and the tubular internal surface of bloom that forms of interweaving by high-strength synthesising fibre and monofilament polyester; By changing circular loom die orifice size, can obtain the tubular pipe of different bores; By changing the diameter of monofilament polyester, can realize that flexible pipe bears the difference of pressure.
The light suction transfusion hose that the method for utilizing present embodiment to provide is made not only can bear high forward discharge pressure, but also can bear negative pressure, and have in light weight, bending radius is little and characteristics such as easy to operate, has enlarged the using scope of flexible pipe; In addition, method provided by the invention can shorten production procedure, reduces equipment investment.
The above only is preferred embodiment of the present invention, and is in order to restriction the present invention, within the spirit and principles in the present invention not all, any modification of being done, is equal to replacement, improvement etc., all should be included within protection scope of the present invention.
