Description

Technical Field

[0001] This utility model belongs to the field of polyaromatic fiber processing technology, and specifically relates to a polyaromatic fiber orientation and alignment guiding mechanism. Background Technology

[0002] Polyaromatic fibers are a class of synthetic fibers with high strength, high modulus, and high temperature resistance. These properties stem from their molecular chain structure, particularly the conjugated aromatic ring system within the molecular chain, which endows them with excellent physical properties. To fully utilize the potential properties of these materials, controlling and optimizing the fiber orientation is crucial.

[0003] Problems with existing technology: Currently, existing polyaromatic fibers cannot easily handle the orientation of the fibers after production, which affects their mechanical properties. At the same time, existing polyaromatic fiber orientation and alignment guiding mechanisms cannot easily rewind the fibers during operation, thus affecting the efficiency of the equipment. Utility Model Content

[0004] The purpose of this invention is to provide a polyaromatic fiber orientation and alignment guiding mechanism that can heat treat polyaromatic fibers through the linkage of a heating box, a stretching mechanism, and a rapid cooling box, thereby improving the crystallinity and orientation of the fibers and enhancing their mechanical properties. The winding mechanism's fixing components allow for easy disassembly and assembly of the winding roller, making the winding of polyaromatic fibers more efficient.

[0005] The specific technical solution adopted by this utility model is as follows: A polyaromatic fiber orientation and alignment guiding mechanism includes a frame, with a roller rotatably mounted inside the frame, a heating box on one side of the roller, and a rapid cooling box on one side of the heating box. A tensioning mechanism is slidably mounted on the surface of the frame, a tensioning mechanism is rotatably mounted on one side of the frame, and a receiving mechanism is provided at one end of the frame. The stretching mechanism includes an electric push rod fixedly installed on one side of the frame, which pushes the stretching assembly to move linearly on the surface of the frame. The stretching assembly includes a connecting frame that is fixedly mounted to a mounting plate. A connecting plate is slidably mounted on one side of the mounting plate via a track groove, and a stretching roller is rotatably mounted on one side of the connecting plate.

[0006] The mounting plates are provided in two sets and arranged in a mirror image. The two sets of mounting plates are slidably mounted on the two side surfaces of the frame. The output shaft of the electric push rod pushes the mounting plates to move horizontally and linearly on the surface of the frame.

[0007] The two ends of the stretching roller are rotatably mounted to the connecting plate. There are two sets of stretching rollers, and the stretching rollers are slidably mounted to the frame. The mounting plate drives the connecting plate to move vertically through the track groove, so that the connecting plate drives the stretching rollers to move synchronously.

[0008] The material receiving mechanism includes a motor fixedly installed on one side of a bracket, a fixing plate fixedly installed on the other side of the bracket, the output shaft of the motor passing through the motor and being connected to the winding roller, and a fixing component fixedly installed on one side of the fixing plate.

[0009] The fixing component includes a second cylinder fixedly installed on one side of the fixing plate. The second cylinder pushes the sliding seat to drive the limit wheel to move inward, so that the sliding seat drives the mounting sleeve to move linearly through the connecting arm.

[0010] The mounting sleeve is hinged to the limiting wheel via a connecting arm. A connecting cylinder is rotatably mounted inside the mounting sleeve. The connecting cylinder is connected to the motor drive. The other end of the connecting cylinder is connected to the take-up roller via a core rod.

[0011] The tensioning mechanism includes a first cylinder, which drives a cam to rotate the tensioning roller assembly, which is rotatably mounted inside the frame.

[0012] The technical effects achieved by this utility model are as follows: This invention utilizes a tensioning mechanism on one side of the idler rollers. This mechanism, activated by a first cylinder, drives a cam to rotate the tensioning roller assembly, thereby dynamically adjusting the tension of the polyaromatic fiber in conjunction with multiple idler rollers. The adjusted polyaromatic fiber is then heated in a heating chamber, and an electric push rod initiates linear motion of the mounting plate. Since the top of the connecting plate slides along a track groove via rollers, the specially designed track groove allows the two connecting plates to adjust the height of the two sets of stretching rollers. This, combined with the linkage of multiple idler rollers, achieves the thermal stretching treatment of the polyaromatic fiber. After cooling in a rapid cooling chamber, the fiber's crystallinity, orientation, and mechanical properties are enhanced.

[0013] This invention utilizes a take-up mechanism at one end of the frame, where a motor mounted on one side of the support drives a connecting cylinder to rotate inside the mounting sleeve. The other end of the connecting cylinder is slidably engaged with the motor's output shaft. The activation of the second cylinder causes the sliding seat to push the mounting sleeve via the connecting arm, moving the connecting cylinder towards the core rod of the take-up roller. A key connection between the connecting cylinder and the core rod enables the motor to drive the core rod, thus achieving the rotation and winding of the take-up roller. Similarly, when disassembling the take-up roller, simply activating the second cylinder to reset it allows for convenient disassembly. Attached Figure Description

[0016] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0017] like Figure 1-7 As shown, a polyaromatic fiber orientation and alignment guiding mechanism includes a frame 1, a roller 4 is rotatably mounted inside the frame 1, a heating box 3 is provided on one side of the roller 4, and a rapid cooling box 2 is provided on one side of the heating box 3. A tensioning mechanism 5 is slidably mounted on the surface of the frame 1, a tensioning mechanism 6 is rotatably mounted on one side of the frame 1, and a receiving mechanism 7 is provided at one end of the frame 1. The tensioning mechanism 5 includes an electric push rod 51 fixedly installed on one side of the frame 1, which pushes the tensioning assembly 52 to move linearly on the surface of the frame 1. The stretching assembly 52 includes a connecting frame 522 fixedly mounted to the mounting plate 521. A connecting plate 524 is slidably mounted on one side of the mounting plate 521 via a track groove 523. A stretching roller 525 is rotatably mounted on one side of the connecting plate 524.

[0018] See attached document Figure 1 , Figure 2 and Figure 3 In this embodiment, two sets of mounting plates 521 are provided and arranged in a mirror image. The two sets of mounting plates 521 are slidably mounted on the two side surfaces of the frame 1. The output shaft of the electric push rod 51 pushes the mounting plates 521 to move horizontally and linearly on the surface of the frame 1.

[0019] In the above embodiment, the two sets of mounting plates 521 are fixedly installed together by two sets of connecting brackets 522. At the same time, a sliding groove is provided inside the mounting plate 521 so that it can be slidably installed on the outside of the frame 1 by sliding rail.

[0020] Furthermore, two sets of stretching rollers 525 are also provided, and the two ends of the stretching rollers 525 are rotatably installed with the connecting plate 524. At the same time, the connecting plate 524 is correspondingly set with the two sets of stretching rollers 525, and the stretching rollers 525 are vertically slidably installed with the frame 1. Therefore, when the electric push rod 51 pushes the mounting plate 521 to move horizontally, the mounting plate 521 can drive the track groove 523 and the connecting plate 524 to move vertically synchronously, thereby causing the connecting plate 524 to drive the stretching rollers 525 to move synchronously.

[0021] It is worth noting that, through the special design of the track groove 523, the vertical movement heights of the two sets of stretching rollers 525 are not consistent, and the heights decrease sequentially compared to the idler rollers 4. Therefore, the stretching rollers 525 and the idler rollers 4 can be linked to stretch the polyaromatic fiber after it has been heated by the heating box 3. The stretched polyaromatic fiber can be cooled by the quick-cooling box 2, thereby improving the crystallinity and orientation of the fiber and enhancing its mechanical properties.

[0022] Please refer to the appendix for details. Figure 1 and Figure 7 As can be further explained, a tensioning mechanism 6 is also installed inside the frame 1. The tensioning mechanism 6 includes a first cylinder 61 hinged to the surface of the frame 1. The output shaft of the first cylinder 61 can be used to drive the cam 62 to drive the tensioning roller group 63 to rotate, so that the tensioning roller group 63 swings inside the frame 1. Through the cooperation of the tensioning roller group 63 and the support roller 4, the tension of the polyaromatic fiber can be adjusted, thereby ensuring the effect of thermal stretching.

[0023] See attached document Figure 1 and Figures 4 to 6In this embodiment, the receiving mechanism 7 includes a motor 72 fixedly installed on one side of the bracket 71, a fixing plate 73 fixedly installed on the other side of the bracket 71, the output shaft of the motor 72 passes through the motor 72 and is connected to the winding roller 74 for transmission, and a fixing component 75 is fixedly installed on one side of the fixing plate 73.

[0024] In the above embodiment, the output shaft of the motor 72 can be driven by the start of the motor 72 to rotate the take-up roller 74, so that the polyaromatic fiber that has been heat-stretched can be automatically wound up. With the setting of the fixing component 75, the take-up roller 74 can be easily disassembled from the inside of the take-up mechanism 7, thereby facilitating the replacement of the take-up roller 74 after it has been wound up.

[0025] According to the above structure, the specific fixing component 75 includes a second cylinder 751 fixedly installed on one side of the fixing plate 73. The output shaft of the second cylinder 751 can push the sliding seat 752 to drive the limiting wheel 753 to move towards the center of the fixing plate 73. By the synchronous movement of multiple sliding seats 752, the sliding seats 752 can push the mounting sleeve 755 to move linearly through the connecting arm 754, so that the mounting sleeve 755 moves towards the take-up roller 74.

[0026] More specifically, a connecting cylinder 756 is rotatably mounted inside the mounting sleeve 755. One end of the connecting cylinder 756 is slidably engaged with the output shaft of the motor 72. Therefore, the motor 72 can drive the connecting cylinder 756 to rotate. At the same time, the other end of the connecting cylinder 756 can be pushed by the mounting sleeve 755 to connect to the take-up roller 74 via the core rod 8. Thus, the motor 72 and the core rod 8 are connected by transmission through the connecting cylinder 756, thereby enabling the take-up roller 74 to rotate and take up the winding.

[0027] It should be noted that after winding is completed, the second cylinder 751 can be activated to move the sliding seat 752 away from the circular part of the fixed plate 73, thereby causing the sliding seat 752 to drive the mounting sleeve 755 and the connecting cylinder 756 to reset synchronously through the connecting arm 754, thereby causing the two ends of the core rod 8 to move out of the inside of the connecting cylinder 756, releasing the restriction on the core rod 8 and the winding roller 74, so that the winding roller 74 can be easily replaced.

[0028] The working principle of this utility model is as follows: the polyaromatic fiber thread passes through the idler roller 4, heating box 3, stretching mechanism 5, and quick-cooling box 2 in sequence, and is then wound up by the take-up mechanism 7. During the processing, the polyaromatic fiber is heated by the heating box 3, and the stretching component 52 is driven to work by the start of the electric push rod 51. Thus, the heated polyaromatic fiber is heat-stretched by the stretching component 52 and the idler roller 4, and then guided by the idler roller 4 to the inside of the quick-cooling box 2 for cooling, thereby improving the crystallinity and orientation of the fiber and enhancing its mechanical properties. The heat-treated polyaromatic fiber can then be wound up by the take-up mechanism 7. After winding, the take-up mechanism 7 can release the limit on the take-up roller 74 by the start of the fixing component 75, so that the take-up roller 74 can be easily replaced from inside the take-up mechanism 7.

[0029] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
