Description

Technical Field

[0001] This utility model relates to the field of para-aramid fiber production technology, specifically to an oiling device for para-aramid fibers. Background Technology

[0002] Para-aramid fiber is a high-performance fiber with ultra-high strength, high modulus and high temperature resistance, and it has wide applications in aerospace, defense and military industry, special protection and other fields.

[0003] In the production and processing of para-aramid fibers, oiling is a key step. Its purpose is to form a uniform oil film on the fiber surface to improve the fiber's bundle properties, antistatic properties, lubricity, and subsequent processing performance, thereby ensuring that the fiber can operate stably in subsequent textile, composite and other processing stages and reducing breakage and damage.

[0004] The prior art patent document CN213835864U provides an oiling device for para-aramid fibers. The device guides the para-aramid fibers through the arrangement of guide rollers, oiling rollers and extrusion rollers, so as to facilitate the smooth and stable entry of the para-aramid fibers into the oil tank. After oiling, the para-aramid fibers are smoothly and stably discharged from the oil tank.

[0005] While the aforementioned existing technology can achieve basic oiling and guiding functions for para-aramid fibers, it still has some shortcomings in actual use. Firstly, the large opening at the top of the oil tank allows external impurities to easily enter. Secondly, the lack of an effective stirring mechanism for the oil in the tank leads to uneven composition and concentration stratification of the oil after prolonged use, resulting in uneven oiling of the fibers and affecting the subsequent processing quality. Furthermore, the existing extrusion structure cannot adjust the distance between the extrusion roller and the rotating roller according to the size of the para-aramid fibers during extrusion oil removal, and therefore cannot effectively adjust the extrusion pressure. Therefore, we need an oiling device for para-aramid fibers. Utility Model Content

[0006] The purpose of this invention is to provide an oiling device for para-aramid fibers, in order to solve the problems mentioned in the background art, such as the lack of an effective stirring mechanism for the oil in the oil tank, and the tendency for the oil to become uneven in composition and stratify after long-term use.

[0007] To solve the above-mentioned technical problems, the present invention provides the following technical solution: an oiling device for para-aramid fibers, comprising an oil tank, a support plate fixedly connected to the outer wall of the oil tank, a hydraulic cylinder fixedly installed on the top of the support plate, a top cover fixedly connected to one end of the hydraulic cylinder, a stirring assembly provided on the outer wall of the top cover, and an extrusion assembly provided at the bottom of the top cover.

[0008] The stirring assembly includes a fixed base, and a fixed bearing is fixedly connected to the inner wall of the fixed base. A servo motor is fixedly installed on the top of the top cover, and a rotating rod is fixedly connected to the output shaft of the servo motor through a coupling. A stirring blade is detachably connected to one end of the rotating rod, and a fixing bolt is provided on the outer wall of the stirring blade.

[0009] The extrusion assembly includes a fixed frame, and a mounting frame is detachably connected to the bottom of the fixed frame. A fastening bolt is provided on the top of the fixed frame, and an extrusion roller is rotatably connected to the inner wall of the mounting frame.

[0010] Preferably, the oil tank has material inlets on both sides, and multiple rotating rollers are rotatably connected to the inner wall of the oil tank. A discharge valve is provided at the bottom of the oil tank, and an observation window is fixedly connected to the inner wall of the oil tank.

[0011] Preferably, the top cover forms a rotating structure with a servo motor and a rotating rod, and one end of the rotating rod passes through a fixed bearing.

[0012] Preferably, the shape and size of the outer wall of the rotating rod match the shape and size of the inner wall of the fixed bearing, and the outer wall of the rotating rod fits into the inner wall of the fixed bearing.

[0013] Preferably, the rotating rod is fixed to the stirring blade by a fixing bolt, and one end of the fixing bolt is threaded through the stirring blade and extends into the rotating rod for connection.

[0014] Preferably, the fixing frame is fixed to the mounting frame by fastening bolts, and one end of the fastening bolt is threaded through the fixing frame and extends into the mounting frame for connection.

[0015] Preferably, the number of rotating rollers is four, and two rotating rollers form a group, one group of rotating rollers is positioned above the oil stored in the oil tank, and the other group of rotating rollers is positioned inside the oil stored in the oil tank.

[0016] Compared with the prior art, the beneficial effects achieved by this utility model are:

[0017] First, this utility model is equipped with a hydraulic cylinder, a top cover, a fixed seat, a fixed bearing, a servo motor, a rotating rod, and a stirring blade. By setting a top cover above the oil tank, the possibility of external impurities entering the oil tank and contaminating the oil agent is effectively reduced. The servo motor drives the rotating rod to rotate the stirring blade, which stirs the oil agent in the oil tank, ensuring that the oil agent composition is uniform and the concentration is consistent. This avoids uneven oiling of the fibers due to oil agent stratification and helps to improve the oiling quality of the fibers.

[0018] Secondly, this utility model is equipped with a fixed frame, a mounting frame, fastening bolts and an extrusion roller. The top cover can be raised and lowered by the operation of the hydraulic cylinder. The movement of the top cover drives the fixed frame to move, which in turn causes the extrusion roller to move. The distance between the extrusion roller and the rotating roller can be adjusted by moving the extrusion roller. The extrusion force can be adjusted according to the size of the paraaramid fiber. Excess oil on the paraaramid fiber can be removed by extrusion, which facilitates subsequent drying and other processes. Attached Figure Description

[0024] 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.

[0025] like Figures 1-4 As shown, an oiling device for para-aramid fibers includes an oil tank 1, a support plate 2 fixedly connected to the outer wall of the oil tank 1, a hydraulic cylinder 3 fixedly installed on the top of the support plate 2, a top cover 4 fixedly connected to one end of the hydraulic cylinder 3, a stirring assembly 5 provided on the outer wall of the top cover 4, and an extrusion assembly 6 provided at the bottom of the top cover 4.

[0026] The stirring assembly 5 includes a fixed base 501, and a fixed bearing 502 is fixedly connected to the inner wall of the fixed base 501. A servo motor 503 is fixedly installed on the top of the top cover 4, and a rotating rod 504 is fixedly connected to the output shaft of the servo motor 503 through a coupling. A stirring blade 505 is detachably connected to one end of the rotating rod 504, and a fixing bolt 506 is provided on the outer wall of the stirring blade 505.

[0027] The extrusion assembly 6 includes a fixed frame 601, and a mounting frame 602 is detachably connected to the bottom of the fixed frame 601. A fastening bolt 603 is provided on the top of the fixed frame 601, and an extrusion roller 604 is rotatably connected to the inner wall of the mounting frame 602.

[0028] Through the above technical solution, by setting a top cover 4 above the oil tank 1, the possibility of external impurities entering the oil tank 1 and contaminating the oil agent is effectively reduced. The servo motor 503 drives the rotating rod 504 to rotate the stirring blade 505, so that the stirring blade 505 stirs the oil agent in the oil tank 1, ensuring that the oil agent composition is uniform and the concentration is consistent, avoiding uneven oiling of the fibers due to oil agent stratification, which is conducive to improving the oiling quality of the fibers. The hydraulic cylinder 3 can realize the lifting and lowering of the top cover 4. The movement of the top cover 4 drives the fixed frame 601 to move, which in turn causes the extrusion roller 604 to move. The distance between the extrusion roller 604 and the rotating roller 8 can be adjusted by moving the extrusion roller 604. The extrusion pressure can be adjusted according to the size of the paraaramid fiber. Excess oil agent on the paraaramid fiber can be removed by extrusion, which facilitates subsequent drying and other processes.

[0029] Specifically, the oil tank 1 has material inlets 7 on both sides, and multiple rotating rollers 8 are rotatably connected to the inner wall of the oil tank 1. The bottom of the oil tank 1 is equipped with a discharge valve 9, and the inner wall of the oil tank 1 is fixedly connected with an observation window 10.

[0030] Through the above technical solution, the bottom of the top cover 4 is fixedly connected to the fixing seat 501, and the bottom of the top cover 4 is bolted to the fixing bracket 601. By opening the discharge valve 9, the oil can be discharged. By setting the observation window 10, it is convenient to observe the situation in the oil tank 1. The oil tank 1 is equipped with a controller. The liquid level of the oil in the oil tank 1 is set within the working range of the stirring blade 505. When the top cover 4 is raised and lowered slightly to adjust the extrusion gap, the stirring blade 505 can still be immersed in the oil to achieve effective stirring. When it is necessary to clean the oil tank 1, thread the parallel aramid fiber, or repair the stirring component, the top cover 4 can be driven to rise significantly by the hydraulic cylinder 3, so that the stirring blade 505 is completely separated from the oil, providing sufficient space for operation.

[0031] Specifically, the top cover 4 forms a rotating structure with the servo motor 503 and the rotating rod 504, and one end of the rotating rod 504 passes through the fixed bearing 502.

[0032] With the above technical solution, when the servo motor 503 is working, it can effectively drive the rotating rod 504 to rotate.

[0033] Specifically, the outer wall shape and size of the rotating rod 504 match the inner wall shape and size of the fixed bearing 502, and the outer wall of the rotating rod 504 fits against the inner wall of the fixed bearing 502.

[0034] Through the above technical solution, the rotating rod 504 is interference-fitted with the inner ring of the fixed bearing 502. When the rotating rod 504 rotates, it rotates stably within the fixed bearing 502.

[0035] Specifically, the rotating rod 504 is fixed to the stirring blade 505 by a fixing bolt 506, and one end of the fixing bolt 506 is threaded through the stirring blade 505 and extends into the rotating rod 504 for connection.

[0036] With the above technical solution, there are two fixing bolts 506, one in front and one behind, which can effectively fix the stirring blade 505 to the rotating rod 504, making it easy to install and disassemble.

[0037] Specifically, the fixing bracket 601 is fixed to the mounting bracket 602 by fastening bolts 603, and one end of the fastening bolt 603 is threaded through the fixing bracket 601 and extends into the mounting bracket 602 for connection.

[0038] With the above technical solution, the number of fastening bolts 603 is four, which can effectively fix the mounting bracket 602 on the fixing bracket 601, making installation and disassembly convenient.

[0039] Specifically, there are four rotating rollers 8, with two rotating rollers 8 forming a group. One group of rotating rollers 8 is positioned above the oil stored in the oil tank 1, and the other group of rotating rollers 8 is positioned inside the oil stored in the oil tank 1.

[0040] The above technical solution uses multiple rotating rollers 8 to guide the para-aramid fibers, allowing them to enter the oil tank 1 for oiling and extending their time in the oil tank 1. This facilitates better immersion of the para-aramid fibers in the oil, improving the oiling quality.

[0041] In use, first connect the device to an external power supply. The external power supply provides power to the device. Adjust the distance between the extrusion roller 604 and the upper right rotating roller 8 according to the size of the aramid fiber. The hydraulic cylinder 3 operates, causing the top cover 4 to move downwards. The top cover 4 moves the fixing frame 601, which in turn moves the mounting frame 602. The mounting frame 602 then moves the extrusion roller 604. Adjust the distance between the extrusion roller 604 and the upper right rotating roller 8 to achieve the appropriate extrusion force. When oiling the aramid fiber, the fiber enters from the feed inlet 7 on the left side of the oil tank 1. Guided by multiple rotating rollers 8, the fiber first passes the upper left rotating roller 8, then passes through a set of rotating rollers 8 below, allowing the fiber to fully enter the oil and facilitating better soaking of the fiber. During the soaking and oiling process, the servo motor 50... 3. In operation, the rotating rod 504 is driven to rotate, which in turn drives the stirring blade 505 to rotate. The stirring blade 505 stirs the oil in the oil tank 1, ensuring that the oil composition is uniform and the concentration is consistent. This avoids uneven oiling of the fibers due to oil layering, which is beneficial to improving the oiling quality of the fibers. After being soaked in the oil, the fibers continue to move under the guidance of the rotating roller 8 and reach the upper right rotating roller 8. When the fibers pass between the extrusion roller 604 and the rotating roller 8, the excess oil on the fibers can be removed by extrusion, making it easier for the fibers to enter subsequent drying and other processes. Throughout the oiling process, the operator can observe the oil status in the oil tank 1 and the oiling status of the fibers through the observation window 10 at any time, so as to promptly detect and deal with any problems that may arise. This completes all the work. The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0042] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
