Detailed description of the invention
Electrostatic spinning nozzle adjustable with the gap shown in Fig. 8 as shown in Figure 1, Figure 2, including feed tube 1, end cap 3 and actuator.
Feed tube 1 is hollow cylindrical, and the end face circular array of bottom shows some micro-ditches 2, and micro-ditch 2 penetrates the inside and outside wall of feed tube 1, thus connects the feed pathway within feed tube 1 and the external world.
On end cap 3, circular array shows some convex tendons 4, in each convex tendon 4 filling one by one ditch 2 in a subtle way, namely is all filled with a convex tendon 4 in the micro-ditch of per pass 2.Described filling refers to that convex tendon 4 enters and is received in micro-ditch 2, and is not necessarily full whole micro-ditch 2, also can there is gap between the most micro-ditch 2 and convex tendon 4.Above-mentioned convex tendon 4 and micro-ditch 2 uniform thickness, after convex tendon 4 fills micro-ditch 2, between the end face that the top end face of convex tendon 4 and the bottom face the two of micro-ditch 2 are relative, only form both gaps, this gap be i.e. spinning solution go out liquid gap 5, spinning liquid from go out liquid gap 5 flow out after can form jet under external electrical field.
Therefore, to be that the entrance feed pathway of feed tube 1 goes out liquid gap 5 extraneous for the flow direction of spinning solution.
Described actuator be used for driving feed tube 1 and end cap 3 to or move dorsad, it connects feed tube 1 and end cap 3 respectively.During both out movements, go out liquid gap 5 and diminish；And both are when moving dorsad, go out liquid gap 5 and become big.Actuator can change the distance liquid gap 5, thus spinning diameter can be as desired to be adjusted.This adjustment is continuous print, for the jet spinning mode of pore type, it is not easy to cause spinning liquid to block.And multiple micro-ditches 2 and multiple convex tendons 4 constitute and say liquid gap 5 more, enable this shower nozzle to spray many jets, substantially increase spinning efficiency and spinning yield.
It is further preferred that referring to figs. 1 to Fig. 4, actuator includes adjusting screw rod 6, it is actually a bolt.The screw portion of this adjusting screw rod 6 is connected with feed tube 1 thread in inner cavity from the bottom to top after end cap 3, and the head 61 of adjusting screw rod 6 abuts end cap 3 end face and end cap 3 is applied the support force towards feed tube 1.The head 61 of adjusting screw rod 6 on-fixed connect end cap 3, and simply play the effect of a support, will not concomitant rotation for this end cap 3.Such as referring to figs. 2 and 3, when rotating clockwise adjusting screw rod 6, adjusting screw rod 6 can be screwed into the deeper position of feed tube 1, then, its head 61 applies thrust upwards to end cap 3, thus reduces the distance liquid gap 5, and the distance now going out liquid gap 5 is h；Otherwise, with reference to Fig. 6 and Fig. 7, rotate counterclockwise adjusting screw rod 6, under the promotion of gravity and spinning solution pressure, end cap 3 compresses downwards adjusting screw rod 6 head 61, and the distance going out liquid gap 5 increases the most therewith, and the distance now going out liquid gap 5 is H, H > h.
Above-mentioned adjusting screw rod 6 is as actuator, it is possible to achieve continuous print adjusts liquid gap 5；Moreover, the silk tooth of screw rod is the closeest, significantly rotates adjusting screw rod 6 and the most simply can change the least distance by going out liquid gap 5, and pole is beneficial to fine setting, meets the adjustment change of spinning diameter wire meter level.
With reference to Fig. 4 and Fig. 8, feed pathway is made up of two parts, is through hole 101 and groove milling 102 respectively.Through hole 101 is downwardly extended by the top end opening of feed tube 1, and the bottom of through hole 101 is connected to screwed hole 103, and adjusting screw rod 6 is threaded on screwed hole 103；Groove milling 102 has three roads, is opened in the outer wall of screwed hole in equilateral triangle shape and in vertically arranged, the top connection through hole 101 of per pass groove milling 102, and bottom passes to micro-ditch 2.
It is further preferred that with reference to Fig. 1 and Fig. 2, the outer wall on feed tube 1 top is provided with the positioning element connecting outside appurtenances.
Specifically, positioning element includes external screw thread 71 and the flange 72 being arranged on feed tube 1 outer wall, flange 72 is between external screw thread 71 and micro-ditch 2, it is preferably hexagon, user can be by rotary flange 72 to drive feed tube 1 to screw in outside appurtenances, and flange 72 is against the end face of outside appurtenances, thus position with outside appurtenances assembling.
With reference to the array spinning system shown in Fig. 9 to Figure 11, including main body 8 and sealing plate 9, main body 8 is upper and lower through to facilitate feed liquor, and sealing plate 9 is sealedly connected on main body 8 bottom, thus surrounding an admission chamber 10 with main body 8 inside, this admission chamber 10 simultaneously works as buffering the effect of spinning solution.Being provided with some screws on sealing plate 9 in array-like, each screw is tightly connected an above-mentioned electrostatic spinning nozzle, the flange 72 of shower nozzle abuts the bottom face of sealing plate 9 thus is positioned by shower nozzle.The feed pathway connection admission chamber 10 of each shower nozzle, receives spinning solution from admission chamber 10.
In embodiment, array shower nozzle on the basis of single shower nozzle spinning, improves the speed of spinning further, greatly adds spinning yield.
It is further preferred that the outer wall of main body 8 is connected to temperature control module 11, in order to control the temperature of spinning solution, meet spinning requirement.
It is further preferred that the top end of main body 8 is provided with the flange arrangement 12 connecting liquid supply part.
The above be this utility model preferred embodiment, it is not intended that the restriction to this utility model protection domain.
