Description

Technical Field

[0001] This application relates to the field of nylon spinning oiling, and more specifically, to an antistatic nylon spinning oiling device. Background Technology

[0002] In the spinning process of nylon, to improve the spinnability of the fibers and reduce friction between monofilaments and between the filament bundle and the guide device, it is usually necessary to "oil" the filament bundle after melt spinning. This involves uniformly coating the surface of the filament bundle with a spinning oil containing antistatic agents, smoothing agents, and emulsifiers. The oiling effect directly affects the breakage rate, hairiness, and static electricity accumulation in subsequent drafting, winding, and even weaving processes.

[0003] In existing technologies, contact oiling with an oil roller is commonly used. The filament bundle passively or actively passes through an oil roller with an oil-coated surface, and oiling is achieved through contact transfer. This method has a simple structure, but it has the following drawbacks:

[0004] The thickness of the oil layer on the surface of the oil roller is uncontrollable. Especially when running at high speed, the oil is easily splashed due to centrifugal force, resulting in oil splashing, slippery ground, and oil waste. When the oil is exposed to the air for a long time, it is easy to volatilize, oxidize and deteriorate, producing "oil sludge" that clogs the oil nozzle and reduces the effective content of the oil. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides an anti-static nylon spinning oiling device, solving the problems mentioned in the background section. To achieve the above objectives, this utility model employs the following technical solution:

[0006] An antistatic nylon spinning oiling device includes an oiling frame, an oiling mechanism inside the oiling frame for oiling nylon yarn, and a guiding mechanism inside the oiling frame for conducting the nylon yarn.

[0007] The oiling mechanism includes: a rotating rod rotatably connected to the inner wall of the oiling frame, with one end of the rotating rod movably passing through the oiling frame and moving backward through it; a roller is fixedly sleeved on the outer wall of the rotating rod; an installation plate is fixedly connected to the inner wall of the oiling frame; and an oil tank is fixedly connected to the top of the installation plate for conveying lubricating oil to the surface of the roller.

[0008] Preferably, the top of the oil tank is equipped with a cover plate, and the bottom of the cover plate is fixedly connected with a plurality of equally spaced fixed sleeves. The bottom of the inner wall of the oil tank is provided with a movable hole, and a movable block is movably connected in the movable hole. The top of the movable block is fixedly connected with a fixed plate, and the top of the fixed plate is fixedly connected with a plurality of equally spaced movable rods, and the movable rods are inserted into the inner wall of the fixed sleeve.

[0009] Preferably, the outer wall of the fixing sleeve is fitted with a spring, and the spring is disposed between the fixing plate and the cover plate, for pushing the fixing plate to drive the movable block to move downward.

[0010] Preferably, the movable block has arc-shaped grooves on its front and rear sides, and the outer wall of the roller is fixedly connected to a plurality of equally spaced protrusions on its front and rear sides, and the outer wall of the protrusions fits into the arc-shaped grooves of the movable block. The movable block has a plurality of oil holes, and when the movable block moves down, the top of the oil holes fits into the bottom opening of the oil tank, and when the movable block moves up, the top of the oil holes protrudes from the bottom of the inner wall of the oil tank.

[0011] Preferably, the oiling rack has an arc-shaped plate inside, and the inner wall of the arc-shaped plate has multiple arc-shaped grooves. The nylon yarn is driven on the outer wall of the roller at the arc-shaped grooves. A recycling box is fixedly connected to the bottom of the inner wall of the oiling rack, and a rectangular oil guide pipe is fixedly connected to the top of the recycling box. The top of the rectangular oil guide pipe is fixedly connected to the bottom of the arc-shaped plate, and the bottom of the arc-shaped plate has a through hole that communicates with the rectangular oil guide pipe.

[0012] Preferably, the guiding mechanism includes: a rotating shaft, rotatably connected to the inner wall of the upper oil frame, and one end of the rotating shaft movably passes through the upper oil frame and extends outward. The outer wall of the rotating shaft is fixedly fitted with a plurality of equally spaced collars. A plurality of circular rods are fixedly connected between every two adjacent collars and are arranged on the collars at equal intervals around the circumference. Nylon filaments are attached to the outer wall of the circular rods for guidance.

[0013] The advantages of this application are:

[0014] (1) This application achieves the intermittent opening and closing of the oil hole by mechanically linking the protrusion and the moving block when the drum rotates, ensuring that the lubricating oil is released only when needed, avoiding waste caused by continuous dripping. The arc plate, the recycling box, and the oil guide pipe form a closed-loop recycling path, effectively collecting excess lubricating oil, reducing oil evaporation and ground pollution, and meeting the requirements of green production.

[0015] (2) In this application, when the movable block moves down, it fits against the outer wall of the roller. Through the cooperation of the arc groove and the protrusion, the lubricating oil is evenly applied to the surface of the nylon yarn, avoiding local over-oil or lack of oil, significantly reducing the accumulation of static electricity caused by friction. In addition, the circumferential distribution of the circular rod makes the nylon yarn transmission path wavy, increasing the contact area between the yarn bundle and the oil surface, ensuring uniform oil penetration, and reducing the risk of breakage caused by single-point stress.

[0025] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are merely some, not all, of the embodiments of the present application. All other embodiments obtained by those skilled in the art based on the embodiments of the present application without creative effort should fall within the scope of protection of the present application.

[0026] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments. Example 1

[0027] See Figures 1-6 This embodiment provides an antistatic nylon spinning oiling device, including an oiling frame 1, an oiling mechanism 2 inside the oiling frame 1 for oiling nylon yarn, and a guide mechanism 3 inside the oiling frame 1 for conducting nylon yarn.

[0028] The oiling mechanism 2 includes: a rotating rod 21, which is rotatably connected to the inner wall of the oiling frame 1, and one end of the rotating rod 21 moves through the oiling frame 1 and moves backward through it. A roller 22 is fixedly sleeved on the outer wall of the rotating rod 21. An installation plate 4 is fixedly connected to the inner wall of the oiling frame 1, and an oil tank 5 is fixedly connected to the top of the installation plate 4 for conveying lubricating oil to the surface of the roller 22.

[0029] A cover plate 6 is installed on the top of the oil tank 5, and a plurality of equally spaced fixed sleeves 26 are fixedly connected to the bottom of the cover plate 6. A movable hole is opened at the bottom of the inner wall of the oil tank 5, and a movable block 24 is movably connected in the movable hole. A fixed plate 25 is fixedly connected to the top of the movable block 24, and a plurality of equally spaced movable rods 27 are fixedly connected to the top of the fixed plate 25. The movable rods 27 are inserted into the inner wall of the fixed sleeves 26.

[0030] A spring 28 is fitted on the outer wall of the fixed sleeve 26, and the spring 28 is located between the fixed plate 25 and the cover plate 6, and is used to push the fixed plate 25 to move the movable block 24 downward.

[0031] The movable block 24 has arc-shaped grooves on its front and rear sides, and multiple equally spaced protrusions 23 are fixedly connected to the front and rear sides of the outer wall of the roller 22. The outer wall of the protrusions 23 fits into the arc-shaped grooves of the movable block 24. Multiple oil holes are provided on the movable block 24. When the movable block 24 moves down, the top of the oil holes fits into the bottom opening of the oil tank 5. When the movable block 24 moves up, the top of the oil holes protrudes from the bottom of the inner wall of the oil tank 5.

[0032] In practical use, the aforementioned device works by wrapping multiple strands of nylon yarn around the outer wall of the roller 22 and transmitting power within each arc-shaped groove, while simultaneously guiding the rotation around the outer wall of the circular rod 33. An external drive device rotates the extension end of the rotating rod 21, causing the roller 22 to rotate. As the roller 22 rotates, it causes the protrusions 23 on its outer wall to rotate, which in turn contact with the arc-shaped grooves of the movable block 24, pushing the movable block 24 upwards. This, in turn, pushes the fixed plate 25 and the movable rod 27 upwards, compressing the spring 28 and releasing the oil from the movable block 24. The upper end of the hole is exposed inside the oil tank 5. At this time, the oil inside the oil tank 5 will penetrate into the lower part of the movable block 24 and drip onto the inner wall of the roller 22. At the same time, when the protrusion 23 is no longer in contact with the arc groove of the movable block 23, the spring 28 will push the fixed plate 25 to move downward, thereby closing the oil hole to the inner wall of the opening of the oil tank 5, thus closing the oil hole. At the same time, the movable block 24 will fit against the outer wall of the roller 22, thereby spreading the lubricating oil that falls on the outer wall of the roller 22 evenly, so that the outer wall of the nylon yarn can be fully coated with oil and reduce the friction of the nylon yarn during transmission. Example 2

[0033] See Figures 1-6Based on Embodiment 1, an arc-shaped plate 9 is provided inside the upper oil rack 1, and multiple arc-shaped grooves are opened on the inner wall of the arc-shaped plate 9. Nylon yarns are driven on the outer wall of the roller 22 at the arc-shaped grooves. A recycling box 7 is fixedly connected to the bottom of the inner wall of the upper oil rack 1, and a rectangular oil guide pipe 8 is fixedly connected to the top of the recycling box 7. The top of the rectangular oil guide pipe 8 is fixedly connected to the bottom of the arc-shaped plate 9, and a through hole is opened at the bottom of the arc-shaped plate 9, which communicates with the rectangular oil guide pipe 8.

[0034] The guiding mechanism 3 includes: a rotating shaft 31, which is rotatably connected to the inner wall of the upper oil frame 1, and one end of the rotating shaft 31 moves through the upper oil frame 1 and extends outward. The outer wall of the rotating shaft 31 is fixedly sleeved with a plurality of equally spaced collars 32. A plurality of circular rods 33 are fixedly connected between each two adjacent collars 32 and are arranged on the collars 32 at equal intervals around the circumference. Nylon filaments are attached to the outer wall of the circular rods 33 for guidance.

[0035] In practical use, during the transmission process, excess lubricating oil on the outer wall of the roller 22 will come into contact with the arc plate 9. At this time, the lubricating oil will enter the through hole in the arc plate 9 and enter the recycling box 7 through the rectangular oil guide pipe 8 for recycling, which further improves the recycling effect and reduces the waste of lubricating oil. At the same time, the circular rod 33 is rotated by the external drive device, which can guide the nylon yarn transmission. The multiple spaced circular rods 33 further perform non-central transmission on the outer wall of the nylon yarn, which improves the elastic contact effect of the nylon yarn during guidance and avoids the nylon yarn from breaking due to uneven force.

[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
