Description

Technical Field

[0001] The utility model relates to the technical field of high-energy carbon fibers, in particular to a wet spinning device. Background Art

[0002] The high-energy carbon fiber wet spinning device is a key equipment for producing high-performance carbon fiber. This device converts carbonized raw materials into fibrous high-performance materials through wet spinning technology. This device is a complex chemical machinery that converts carbonized raw materials (such as polyacrylonitrile or other organic fiber precursors) into carbon fibers by controlling chemical reactions and physical processes. This process involves multiple steps such as solution preparation, fiber formation, solvent removal and fiber solidification.

[0003] In solution preparation, first, a spinning solution containing carbonized raw materials needs to be prepared, which usually involves dissolving the raw materials in a solvent to form a uniform solution. The solution is fed into the spinning machine through a spinning pump and dripped into a coagulation bath through a spinning nozzle. The coagulation bath is usually hot water or an organic solvent, which allows the solution to quickly solidify into fibers. The fibers formed in the coagulation bath need to remove the solvent, and this step is usually completed by heat treatment or natural drying. After the solvent is removed, the fibers need to be further solidified to improve their mechanical strength and durability.

[0004] With the development of technology, high-energy carbon fiber wet spinning equipment tends to be automated and intelligent, in order to improve production efficiency and product quality, improve energy utilization and waste treatment in the spinning process, and reduce environmental pollution, which is an important direction for future development. In addition, by developing new carbonized raw materials and spinning solutions, carbon fibers with higher performance or lower cost can be produced.

[0005] During the spinning process, parameters such as temperature, pressure and flow rate are controlled by computers to ensure the quality and output of the fibers. At the same time, nanomaterials are used to modify the spinning solution to produce high-energy carbon fibers with special properties. Compared with traditional intermittent spinning, continuous spinning technology can greatly improve production efficiency.

[0006] The high-energy carbon fiber wet spinning device is usually composed of a solution preparation system, a spinning system, a coagulation bath system, a solvent removal system, a solvent removal system and a fiber curing system. The solution preparation system includes raw material storage, dissolution and filtration equipment to ensure the quality and uniformity of the spinning solution. The spinning system includes a spinning pump, a nozzle, a computer control system, etc. to accurately control the fiber formation process. The coagulation bath system includes a bath, a temperature control system, etc. to quickly cure the fiber and form a preliminary fiber structure. The solvent removal system includes a heat treatment device or a drying equipment to remove the solvent from the fiber and form a stable fiber structure. The fiber curing system includes a hot air furnace or an oven to further improve the mechanical strength and durability of the fiber.

[0007] Existing wet spinning devices are generally designed to deal with the inevitable fluctuation of linear density during the spinning process of the raw silk. However, when the linear density fluctuates greatly, it will seriously affect the performance stability of the carbon fiber. Therefore, controlling the linear density to be uniform and reducing the linear density fluctuation will greatly improve the fiber quality and is being improved. For example, the carbon fiber wet spinning device disclosed in the authorized Chinese patent CN213172712U can be used in conjunction with structures such as a coagulation tank, a partition, a coagulation tank channel, a coagulation liquid inlet, a spinneret, a feed plate, a feed port, a spinneret, a clustering cylinder, a first traction roller and a second traction roller to ensure that the feed amount of the three feed ports is consistent through a precision metering pump to ensure uniform spinning. At the same time, the clustering cylinder and the first traction roller are designed to control the tension of the primary fiber and reduce bleaching. In addition, a partition is added to the coagulation tank to reduce shaking and bleaching caused by turbulence.

[0008] However, the wet spinning device in the above-mentioned cited document needs to convert the organic fiber raw materials into carbon fibers through chemical treatment when in use. This process requires the fiber raw materials to maintain a stable motion trajectory in the spinning solution. However, due to the lack of an effective limiting device in the device, the fiber raw materials are difficult to be accurately controlled during high-speed rotation and stretching, and are easily deviated from the predetermined path, resulting in the occurrence of wire running. Wire running not only leads to waste of raw materials and increased production costs, but more importantly, it may cause mechanical failures of the spinning device, such as broken yarn shafts, clogging of spinning nozzles, etc. These failures will seriously affect the normal operation and production efficiency of the device. In addition, wire running may also cause accumulation of fibers in the spinning chamber, which not only affects the quality of the fibers, but may also cause safety accidents such as fires, posing a threat to the safety of operators, thereby resulting in the use effect of existing carbon fiber wet spinning devices to be improved.

DETAILED DESCRIPTION

[0030] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0031] See also Figure 1-4 The utility model provides a technical solution: a wet spinning device, comprising a workbench 1, a supporting rotating frame 2 and a pulling roller 3, wherein the supporting rotating frame 2 is fixedly installed on a side of the workbench 1 away from the ground by bolts, and the number of the supporting rotating frames 2 is two and they are distributed in a mirror-symmetrical manner, and the opposite sides of the two supporting rotating frames 2 are rotatably connected to the two ends of the pulling roller 3 through bearings respectively; two sets of dynamic limit mechanisms 400 in a mirror-symmetrical manner are installed on the outer side of the pulling roller 3;

[0032] Through the mutual cooperation between the supporting rotating frame 2, the traction roller 3 and the dynamic limiting mechanism 400 on the workbench 1, a dynamic limiting function can be provided to improve the stability and accuracy of the spinning process, thereby ensuring that the fiber raw material always maintains a stable motion trajectory during the spinning process, reducing the occurrence of wire running, reducing raw material waste and reducing maintenance costs caused by mechanical failures, thereby improving the operating efficiency of the production line.

One side of the gear driving component is connected to an adjusting moving component that is slidably connected in the adjusting control box 403. An arc-shaped clamping plate 408 is installed on the side of the adjusting moving component close to the traction roller 3.

[0036] It should be noted that the connecting support assembly includes a supporting mounting block 4021 and a connecting rod 4022; one side of the supporting mounting block 4021 is fixedly installed on the side of the conical moving cylinder 401 close to the supporting rotating frame 2 by bolts, one end of the connecting rod 4022 is fixedly installed on the end of the supporting mounting block 4021 away from the conical moving cylinder 401 by bolts, and the other end is fixedly installed on one side of the adjusting control box 403 by bolts, so as to be able to stably support the adjusting control box 403.

[0037] It can be understood that the power assembly includes a bearing support 4051, a worm 4052, a rotating handle 4053 and a worm wheel 4054; one side of the bearing support 4051 is fixedly mounted on the inner side wall of the rotating groove 404, one end of the worm 4052 is rotatably connected to one side of the bearing support 4051 through a bearing, and the other end penetrates the adjustment control box 403 and extends to the outside of the adjustment control box 403 and is fixedly connected to the rotating handle 4053;

[0038] The rotating handle 4053 drives the worm 4052 to rotate, so as to drive the worm wheel 4054 meshed with the worm 4052 to rotate, so as to stably drive the gear driving assembly to rotate.

[0039] In addition, the gear drive assembly includes a rotating rod 4061 and a follower spur gear 4062; the two ends of the rotating rod 4061 are rotatably connected to the inner wall of the rotating groove 404 through bearings, the inner side of the follower spur gear 4062 is fixedly connected to the outer side of the rotating rod 4061, and the outer side of the rotating rod 4061 is fixedly connected to the inner side of the worm gear 4054 and rotates with the worm gear 4054, so as to be able to stably drive the follower spur gear 4062 to rotate.

[0040] In this embodiment, the adjusting moving component includes a moving tooth plate 4071 and a limiting fixing plate 4072; one side of the moving tooth plate 4071 is meshed with the outer side of the follower spur gear 4062, one side of the limiting fixing plate 4072 is fixedly installed on the side of the moving tooth plate 4071 away from the traction roller 3, and the other side is fixedly connected to one side of the arc-shaped clamping plate 408, and the side of the arc-shaped clamping plate 408 away from the moving tooth plate 4071 is in contact with the outer side of the traction roller 3, so that the arc-shaped clamping plate 408 can be pushed to move by the moving tooth plate 4071, so that the distance between the two conical moving cylinders 401 can be adjusted, thereby performing dynamic adjustment.
