Description

Technical Field

[0001] This utility model relates to the field of composite spinneret technology, specifically a composite spinneret structure. Background Technology

[0002] A spinneret, also known as a spinning cap, is used to transform viscous polymer melts or solutions into fine streams with specific cross-sectional shapes through micropores. These streams are then solidified by a coagulation medium such as air or a coagulation bath to form filaments. Spinnerets can be classified as: ordinary types, which can be further divided into melt spinning spinnerets (which come in round, rectangular, and fan-shaped shapes) and wet spinning spinnerets (also known as spinning caps); shaped spinnerets, which produce fibers with non-circular cross-sections; and composite spinnerets, used to manufacture composite fibers.

[0003] Chinese Patent Publication No. CN220300928U discloses a composite spinneret structure that can be quickly assembled and disassembled. The spinneret body is a circular spinneret assembled from several fan-shaped spinnerets. The fan-shaped spinnerets have arc-shaped side grooves and straight side grooves. A support frame is provided on the inner side of the lower cover ring. When assembling the composite spinneret, the arc-shaped side grooves and straight side grooves on the fan-shaped spinnerets are aligned with the second ring groove on the lower cover ring and the support frame, respectively, and locked in place. This allows several fan-shaped spinnerets to be assembled in a circular shape inside the lower cover ring. When the spinneret holes on the corresponding part of the fan-shaped spinneret are damaged, that fan-shaped spinneret can be removed and replaced without replacing the entire spinneret, reducing the replacement and maintenance cost of the composite spinneret and facilitating the replacement, maintenance, and use of the composite spinneret.

[0004] Although the aforementioned patent allows for the replacement of one of the damaged fan-shaped spinnerets, the replacement process requires the complete separation of the upper and lower cover rings to remove the damaged fan-shaped spinneret. Since the upper and lower cover rings are fixed together by multiple bolts, disassembly and installation are time-consuming and can lead to reduced spinneret efficiency. Utility Model Content

[0005] The purpose of this invention is to provide a composite spinneret structure to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A composite spinneret structure, comprising:

[0008] A base support, the top surface of which is fixedly connected to a limit ring;

[0009] An arc-shaped plate is set above the base and is detachably connected to the base. Multiple arc-shaped plates are provided and distributed at equal angles along the circular ring of the base. A retaining plate is fixedly connected to the bottom surface of the arc-shaped plate at the corresponding limiting ring.

[0010] A fan-shaped spinneret is disposed between the base and the arc-shaped plate. Multiple fan-shaped spinnerets are provided and are detachably connected to the base and the corresponding arc-shaped plate. The top and bottom surfaces of the fan-shaped spinnerets are provided with slots.

[0011] Furthermore, the top surface of the base is fixedly connected to a fixing ring, and both the fixing ring and the top surface of the base are provided with multiple through holes at equal angles. The bottom surface of the arc-shaped plate is fixedly connected to a sealing plate that is in close contact with the fixing ring, and the sealing plate and the bottom surface of the arc-shaped plate are provided with through holes at corresponding through holes.

[0012] Furthermore, the fan-shaped spinneret has grooves on both sides, and the top surface of the base is fixedly connected with multiple brackets that engage with two grooves at corresponding positions. One end of each bracket is at the center of the base, and the multiple brackets are fixedly connected. The top surface of each bracket is fixedly connected with an airbag that engages with two grooves at corresponding positions, and the interiors of the multiple airbags are interconnected.

[0013] Furthermore, one end of the airbag is fixedly connected to an air nozzle that penetrates the limiting ring and the fixing ring, and the air nozzle communicates with the interior of the airbag at the corresponding position.

[0014] Furthermore, the cross-section of the groove is an inverted convex structure.

[0015] Furthermore, sealing gaskets are fixedly connected to the outer sides of both the limiting ring and the card plate.

[0016] Furthermore, rubber pads are fixedly connected to the ends of the arc-shaped plate, the sealing plate, and the clamping plate.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. When one of the fan-shaped spinnerets is damaged, the corresponding arc plate can be removed from the base first, then the damaged fan-shaped spinneret can be removed and a brand new fan-shaped spinneret can be installed. Therefore, when replacing a damaged fan-shaped spinneret, it is only necessary to remove the arc plate corresponding to the damaged fan-shaped spinneret from the base 1. It is not necessary to remove multiple arc plates, which can improve the installation and removal efficiency of the fan-shaped spinneret and improve the fiber spinning efficiency.

[0019] 2. Inflate multiple air bladders through one of the air nozzles, causing the air bladders to expand and fit into the two corresponding grooves. The expansion of the air bladders can squeeze the two adjacent fan-shaped spinnerets, making the two adjacent fan-shaped spinnerets fit tightly together, thereby increasing the sealing between the two adjacent fan-shaped spinnerets and preventing the fibers from entering the gap between the two adjacent fan-shaped spinnerets during the spinning process.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1 - Figure 5 In this embodiment of the utility model, a composite spinneret structure includes a base 1, a limiting ring 13 fixedly connected to the top surface of the base 1, an arc plate 2 detachably connected above the base 1, multiple arc plates 2 are provided and distributed at equal angles along the circular ring of the base 1, a retaining plate 23 is fixedly connected to the bottom surface of the arc plate 2 corresponding to the limiting ring 13, multiple fan-shaped spinnerets 3 are provided between the base 1 and the arc plate 2, and are detachably connected to the base 1 and the arc plate 2 at the corresponding positions, and the top and bottom surfaces of the fan-shaped spinnerets 3 are provided with retaining grooves 31.

[0028] Specifically, firstly, multiple fan-shaped spinnerets 3 are sequentially installed on the base 1, forming a circle, with the slots 31 below the fan-shaped spinnerets 3 engaged in the limiting rings 13. Then, multiple arc-shaped plates 2 are sequentially installed on the corresponding fan-shaped spinnerets 3, forming a ring structure. A retaining plate 23 is engaged in the slots 31 on the top surface of the corresponding fan-shaped spinnerets 3. Finally, bolts are used to fix the multiple arc-shaped plates 2 to the base 1. At this point, the multiple fan-shaped spinnerets 3 are fixed between the base 1 and the corresponding arc-shaped plates 2. The fan-shaped spinneret 3 and multiple arc-shaped plates 2 form a whole, and then the whole is installed in the spinneret equipment. When one of the fan-shaped spinnerets 3 is damaged, the corresponding arc-shaped plate 2 can be removed from the base 1 first, and then the damaged fan-shaped spinneret 3 can be removed and replaced with a brand new fan-shaped spinneret 3. Therefore, when replacing the damaged fan-shaped spinneret 3, it is only necessary to remove the arc-shaped plate 2 corresponding to the damaged fan-shaped spinneret 3 from the base 1, without removing multiple arc-shaped plates 2. This can improve the installation and removal efficiency of the fan-shaped spinneret 3 and improve the fiber spinning efficiency.

[0029] Example 1

[0030] like Figure 2 and Figure 3 As shown, in this embodiment, a fixing ring 11 is fixedly connected to the top surface of the base 1. Both the fixing ring 11 and the top surface of the base 1 are provided with multiple through holes 12 at equal angles. A sealing plate 21 that is in close contact with the fixing ring 11 is fixedly connected to the bottom surface of the arc plate 2. Through holes 22 are provided at the corresponding through holes 12 on the bottom surfaces of the sealing plate 21 and the arc plate 2.

[0031] In this embodiment, the arc plate 2 can be fixed to the base 1 with bolts, so that when the staff replaces the damaged fan-shaped spinneret 3, they only need to remove the arc plate 2 at the corresponding position. This makes it easy for the staff to install and remove the fan-shaped spinneret 3 without having to remove multiple arc plates 2.

[0032] Example 2

[0033] like Figure 2 - Figure 5As shown, in this embodiment, grooves 32 are provided on both sides of the fan-shaped spinneret 3. Multiple brackets 14 are fixedly connected to the top surface of the base 1 at equal angles and are engaged with the two grooves 32 at corresponding positions. One end of each bracket 14 is at the center of the base 1 and the multiple brackets 14 are fixedly connected. An airbag 15 is fixedly connected to the top surface of the bracket 14 and is engaged with the two grooves 32 at corresponding positions. The interiors of the multiple airbags 15 are interconnected. One end of the airbag 15 is fixedly connected to an air nozzle that passes through the limiting ring 13 and the fixing ring 11. The air nozzle is connected to the interior of the airbag 15 at the corresponding position. The cross-section of the groove 32 is an inverted convex structure. Sealing gaskets are fixedly connected to the outer sides of the limiting ring 13 and the clamping plate 23. Rubber gaskets are fixedly connected to the ends of the arc plate 2, the sealing plate 21 and the clamping plate 23.

[0034] In this embodiment, after the multiple fan-shaped spinnerets 3 and multiple arc-shaped plates 2 are installed, air is injected into the multiple air bladders 15 through one of the air nozzles, causing the air bladders 15 to expand and fit into the two grooves 32 at the corresponding positions. The expansion of the air bladders 15 can squeeze the two adjacent fan-shaped spinnerets 3, making the two adjacent fan-shaped spinnerets 3 fit tightly together, thereby increasing the sealing between the two adjacent fan-shaped spinnerets 3 and preventing the fiber from entering the gap between the two adjacent fan-shaped spinnerets 3 during the spinning process.

[0035] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0036] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
