The specific embodiment
Below in conjunction with specific embodiment, further set forth the utility model.Should be understood that these embodiment only to be used to the utility model is described and be not used in the restriction scope of the present utility model.Should be understood that in addition those skilled in the art can make various changes or modifications the present invention after the content of having read the utility model instruction, these equivalent form of values fall within the application's appended claims institute restricted portion equally.
Embodiment 1
The utility model relates to a kind of multiple spray head static spinning machine of spray up, mainly comprises ejecting device, automatic infusion device 2, HV generator 4 and four parts of winding mechanism.Wherein high pressure generator adopts F10-II type HV generator; The reciprocating motion of shower nozzle case 1 provides compressed air by ZB-0.1/8 type air compressor, provides reciprocating motion power by Cylinder SC50-500, with two travel switch 7LX19-001 controlled motions back and forth.Winding mechanism 100YYJ-250 type GEAR MOTOR transmission.Its technological process is: open total power switch → open HV generator power supply with preheating HV generator → the start automatic infusion device control cabinet valve of infusing → open, the shower nozzle case begins reciprocating motion → open high pressure generator high-voltage switch gear, adjust voltage, beginning spinning → open winding mechanism motor switch, after finishing, motor speed adjusting base cloth translation speed → spinning turns off automatic infusion device thereby regulate, stop to infuse → turn off the high pressure generator high-voltage switch gear, stop spinning → the turn off power supply of winding mechanism motor, what stop base cloth batches → turns off the control cabinet valve, stops the power supply of the reciprocating motion of shower nozzle case → turn off high pressure generator → turn off total power switch → take off from the work beam base cloth that has spun fiber.Realize by the following method:
(1) direction of spinning head, shape and distribution
Base cloth is positioned at the top of spinning head 3, and spinning head 3 sprays up, sees Fig. 1.The infusion set of accurate design can remove spinning solution with certain pressure or flow volume delivery to each shower nozzle.Drop not can as down the spray device in drop onto on the felt that is spun into, be broken to the felt quality.
Nozzle structure is seen Fig. 2, makes the shower nozzle tip form the drop of certain radian, and electric field force is easy to overcome the surface tension of solution like this.And, make each shower nozzle can extract a plurality of jets simultaneously out by improving solution and optimizing spinning technology parameter, improved the output of single shower nozzle.The a plurality of spinning heads of combination are seen Fig. 3 in the shower nozzle case, adjust distance and distribution between the shower nozzle, make between the shower nozzle that the interference between the jet is as far as possible little, thereby have guaranteed the uniformity of spinning, further improve the output of electrostatic spinning.The distance of a plurality of shower nozzles and distribute can also guarantee that each shower nozzle can extract a plurality of jets simultaneously out, and electric field influences each other lessly between shower nozzle, cooperates the motion of shower nozzle case and winding mechanism, make spinning evenly, quality of finished product good.
(2) adopt housing and shower nozzle case electric field shielding.
Distance between the multi-nozzle electrospinning shower nozzle is less, and electric field phase mutual interference between shower nozzle is isolated so need between the shower nozzle to be used for to shield, and as shown in Figure 2, single shower nozzle is made up of metal shower nozzle 3b and lucite housing 3a.Housing around the metal shower nozzle can partly shielding effect falls the interference of electric field between shower nozzle and the shower nozzle, and it is less to make between the shower nozzle that electric field disturbs, and electric field is more stable.Machine is made shelf with iron, and when the shower nozzle case moved near frame, frame was bigger to the shower nozzle electric field effects, the electric field instability that makes spinning, and also the shower nozzle case is reciprocating, has increased the instability of frame to the shower nozzle electric field influence.The shower nozzle case is seen Fig. 1 in the utility model, can shield frame and ambient substance to many shower nozzles electric field effects in the case, has further improved the stability of spinning electric field, makes spinning stable, thereby improves into the felt quality.
(3) many shower nozzles and base cloth motion respectively in vertical direction
Many ejecting devices jet beam is more concentrated, jet volatilizees in spinning journey does not have single shower nozzle desirable like that, and fiber volatilizees not exclusively in the fibrofelt of collecting, and shower nozzle case and base cloth all move in the utility model, make the fibrofelt internal solvent that the enough volatilization time be arranged, the felt quality of collecting is better.As shown in Figure 1, shower nozzle case 1 is done straight reciprocating motion by electric control box 6 controls.And by electric control box 6 control shower nozzle casees 1 reciprocating direction and speed.The coiling of base cloth 5 is finished by machinery control 8.The translation of the base cloths that the reciprocating motion of the shower nozzle case 1 of electric control box 6 control and machinery control 8 are controlled adds that many shower nozzles spray more uniformly that to make into the felt quality even, can realize the industrialization of electrostatic spinning.
(4) precision of infusion set design
Liquid level need keep certain shape on the shower nozzle, makes the surface tension of liquid less like this, applies the electric field that less high pressure obtains and extracts jet out with regard to being enough to overcome solution surface tension.Solution in many shower nozzles that the utility model adopts is communicated with, and solution can be with certain pressure or flow volume delivery to each shower nozzle.Solution is with high voltage in the process of spinning, thus the engine of automatic infusion device 2 and the pump housing insulate, make in the solution with high-tension electricity can not have influence on the rotation of engine.The utility model infusion set can be infused automatically continuously, for the serialization production of spinning machine provides prerequisite.
