Description

Technical Field

[0001] This invention relates to the field of fiber material processing technology, and in particular to a biomimetic spinneret. Background Technology

[0002] The emergence of bionics has greatly enriched human imagination and broadened our perspectives. To promote the application and development of high technology in the textile industry, we need to seek inspiration from the biological world and conduct simulations. Applying bionic principles to fiber design and production is a crucial aspect and innovation in fiber development.

[0003] Patent document CN110725018B, entitled "A Bionic Anti-clogging Spinneret for Electrospinning," discloses a bionic anti-clogging spinneret for electrospinning. The bionic anti-clogging spinneret consists of a feed chamber and a bionic spinneret. The bionic spinneret is an integral structure consisting of a nozzle body and a mounting base. The mounting base is threadedly fixed to the threaded interface of the feed chamber. The slurry in the feed chamber enters the bionic spinneret through the threaded interface.

[0004] The above-mentioned technical solution has a biomimetic spinneret inner surface designed as conical, which gives the slurry fluid transport pipeline a certain taper, which can buffer the turbulence phenomenon caused by the sudden change of pipe diameter, thereby improving the uniformity and stability of the slurry fluid and further improving the spinneret's spinning quality. However, the filament material produced by this type of biomimetic spinneret is mostly single-line, and this type of filament material is difficult to provide greater toughness. Summary of the Invention

[0005] The purpose of this invention is to propose a biomimetic spinneret that can enhance the toughness of spinneret products.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A biomimetic spinneret includes a plate body with a trapezoidal groove and a plurality of spinnerets. One end of each spinneret is connected to the trapezoidal groove. Each spinneret is provided with a reinforcing component, which is detachably connected to the corresponding spinneret. The reinforcing component includes a first micropore and a plurality of second micropores. The spinning solution ejected from the second micropores is entangled with the spinning solution ejected from the first micropores.

[0008] Preferably, the reinforcing component further includes a cylinder, one end of which facing the trapezoidal groove is fixedly connected to a common guide groove for spinning solution. The first micropore is formed on the central axis of the cylinder and penetrates the cylinder. A plurality of second micropores are formed on the cylinder and penetrate the cylinder. The plurality of second micropores are arranged circumferentially around the first micropore.

[0009] Preferably, the first micropore is cylindrical, the second micropore is S-shaped, and the end of the second micropore facing the trapezoidal groove and the end of the first micropore facing the trapezoidal groove are both connected to the guide groove of the spinning solution.

[0010] Preferably, the outer wall of the cylinder is provided with external threads, the spinneret hole is provided with internal threads, and the cylinder is threadedly connected to the spinneret hole.

[0011] Preferably, the plate body has multiple circular grooves, which are connected to the corresponding spinnerets, and the central axis of the circular grooves coincides with the central axis of the corresponding spinnerets. The diameter of the circular grooves is larger than the diameter of the spinnerets.

[0012] Preferably, an annular magnetic block is placed in the circular groove, the outer diameter of the magnetic block is adapted to the circular groove, and the inner diameter is adapted to the spinneret orifice. The cylinder is made of a magnetic material that can be magnetically attracted to the magnetic block.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0014] 1. This invention sets a first micro-hole and multiple second micro-holes in each spinneret, so that the spinning solution sprayed from the second micro-holes is entangled with the spinning solution sprayed from the first micro-holes, so that the single-line fiber product is transformed into multi-strand curved fiber on the basis of the first micro-holes, which can significantly enhance the toughness of the spinneret product and thus produce fiber products with better biomimetic functions.

[0015] 2. By setting a common guide channel for spinning solution at each spinneret, the present invention can avoid the mixing of fiber products ejected from different spinnerets and reduce the probability of defective products. Attached Figure Description

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0023] Reference Figures 1-3 A biomimetic spinneret includes a plate body 10, which has a trapezoidal groove 11 and a plurality of spinnerets. One end of each spinneret is connected to the trapezoidal groove 11. Each spinneret is provided with a reinforcing component, which is detachably connected to the corresponding spinneret. The reinforcing component includes a first microhole 20 and a plurality of second microholes 21. The spinning solution sprayed from the second microholes 21 is entangled with the spinning solution sprayed from the first microholes 20.

[0024] Furthermore, the reinforcing component also includes a cylinder 22, one end of which facing the trapezoidal groove 11 is fixedly connected to a common guide groove 25 for spinning raw materials. A first micropore 20 is opened on the central axis of the cylinder 22 and penetrates the cylinder 22. A plurality of second micropores 21 are opened on the cylinder 22 and penetrate the cylinder 22. The plurality of second micropores 21 are arranged circumferentially around the first micropore 20.

[0025] Reference Appendix Figure 2 The common guide channel 25 for spinning raw materials is shaped like a frustum, and a frustum-shaped channel is opened inside the frustum, which runs through the entire common guide channel 25 for spinning raw materials. It is approximately funnel-shaped, and its smaller end is fixedly connected to the cylinder 22.

[0026] The purpose of setting up a common guide channel 25 for spinning solution is to avoid mixing of fiber products ejected from different spinnerets.

[0027] Furthermore, the first micropore 20 is cylindrical, and the second micropore 21 is S-shaped. The end of the second micropore 21 facing the trapezoidal groove 11 and the end of the first micropore 20 facing the trapezoidal groove 11 are both connected to the spinning solution shared guide groove 25.

[0028] The diameter of the first micropore 20 can be larger than that of the second micropore 21 so that the spinning solution extruded from the first micropore 20 can be better wrapped by the spinning solution extruded from the second micropore 21, thereby producing a better biomimetic functional fiber.

[0029] Furthermore, the outer wall of the cylinder 22 is provided with external threads, and the spinneret hole is provided with internal threads, so that the cylinder 22 is threadedly connected to the spinneret hole.

[0030] By using a threaded connection, the cylinder 22 is acted upon, causing it to screw in and out of the corresponding spinneret hole, thus achieving a detachable connection between the cylinder 22 and the corresponding spinneret hole.

[0031] Furthermore, the plate 10 has multiple circular grooves 23, which are connected to the corresponding spinnerets, and the central axis of the circular grooves 23 coincides with the central axis of the corresponding spinnerets. The diameter of the circular grooves 23 is larger than the diameter of the spinnerets.

[0032] Furthermore, an annular magnetic block 24 is placed inside the circular groove 23. The outer diameter of the magnetic block 24 is adapted to the circular groove 23, and the inner diameter is adapted to the spinneret hole. The cylinder 22 is made of magnetic material and can be magnetically attracted to the magnetic block 24.

[0033] By using magnetic attraction, the cylinder 22 placed in the spinneret hole is magnetically restricted and relatively fixed therein. It can also be removed, thus achieving a detachable connection between the cylinder 22 and the corresponding spinneret hole.

[0034] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
