Nylon 6 spinning low-friction oiling roller device

Abstract

This utility model relates to the field of nylon spinning production technology, specifically to a low-friction oiling roller device for nylon 6 spinning, comprising: at least one guide bar installed on the top of a support plate; at least one thread guide component, both connected to the mounting frame, which is connected to the support plate. Cooled nylon 6 filaments pass through the surface of the guide bar along one side of the support plate and through the corresponding thread guide component. This utility model removes the original filament separator and guide bar, and replaces the ceramic ring with a pigtail hook to form a new bundle point. The bundle point is lower than existing equipment, allowing the filaments to naturally fall to the oiling mechanism inlet, which helps improve the oil coverage of the monofilaments. Because the entire yarn path is simpler and the thread friction is lower, it can adapt to higher production speeds. The yarn start-up operation is also simpler, requiring only the filaments to be hooked into the pigtail hook, reducing the start-up time from over one minute to less than 10 seconds.

Description

Technical Field

[0001] This utility model relates to the field of nylon spinning production technology, and more specifically to a low-friction oiling roller device for nylon 6 spinning. Background Technology

[0002] In the pre-drawing preparation stage of nylon 6 spinning, after the multi-strand melt-spun raw yarn is cooled and solidified, it needs to be oiled to impart lubricity and antistatic properties to the fiber before it can enter the first hot roller for crucial drawing and heat setting. To ensure effective oiling and smooth, stable feeding of the yarn bundle into the first hot roller, a bundling point needs to be set before the yarn bundle enters the oil pan to initially gather any loose raw yarn. Simultaneously, to prevent yarn bundle tangling and guide its path, traditional processes typically include a yarn separator and two yarn guides on the yarn path after the bundling point and before the oil pan / first hot roller.

[0003] In particular, the bundle gathering point is usually located high and far from the oil pan. The filament bundle needs to pass through the splitter and guide multiple times to reach the surface of the oil pan after coming out of the bundle gathering point. Friction will be generated at each contact point. Although the surface of the metal or ceramic guide is smooth, the accumulated friction from multiple contacts is still considerable. This continuous friction will scratch the surface of the monofilament, producing a large number of fuzzy fibers, which seriously affects the appearance quality and physical properties of the filament and is one of the main reasons for the production of downgraded products.

[0004] Although the original purpose of filament splitters and guides is to split and guide filaments, the negative effects they introduce (friction, complex paths) are becoming increasingly mismatched with the current production requirements of pursuing high quality, high efficiency, and low loss, and have even become the source of major problems. Utility Model Content

[0005] To address the technical problems existing in the oiling rollers for nylon 6 filaments in the prior art, the first aspect of this utility model proposes a low-friction oiling roller device for nylon 6 spinning, comprising:

[0006] At least one guide wire rod is installed on the top of the support plate;

[0007] At least one thread guide component is connected to the mounting bracket, which is connected to the support plate. The cooled nylon 6 filament bundle passes through the corresponding thread guide component along one side of the support plate via the surface of the guide bar.

[0008] Oiling mechanism;

[0009] The thread guide component is installed above the oiling mechanism inlet, and the thread guide component is used as the gathering point of the nylon 6 filament bundle. There is no filament splitter or filament guide between the thread guide component and the oiling mechanism inlet.

[0010] The mounting bracket is configured to be detachably mounted to a predetermined area on the surface of the support plate, making the position of the thread guide adjustable, so that the nylon 6 yarn bundles that fall after being bundled by the thread guide can directly enter the inlet of the oiling mechanism.

[0011] Preferably, the line guide component includes a pigtail hook.

[0012] Preferably, the top of the support plate is provided with two wire guides, and the mounting bracket is provided with two wire guide components.

[0013] Preferably, the mounting bracket is mounted horizontally to the surface of the support plate.

[0014] Preferably, each of the wire guide components can be adjusted in its mounting position along the length of the mounting bracket.

[0015] Preferably, each of the wire guide components is located directly below the wire guide bar.

[0016] Preferably, the oiling mechanism includes an oil pan, an oil lip, or an oil roller.

[0017] Preferably, the oiling mechanism includes an oil pan and a guide roller connected to a support plate. The guide roller is located above one side of the oil pan, and the nylon 6 filament bundle hanging from the gathering point passes around the oil pan and the guide roller in sequence, with more than two turns.

[0018] Preferably, the axis of the oil pan is located on one side of the midpoint of the line connecting the two wire-passing components.

[0019] Compared with the prior art, the nylon 6 spinning low-friction oiling roller device proposed in this utility model uses a pig tail hook to replace the ceramic ring to form a new gathering point. The gathering point is lower than that of the existing equipment, and the yarn naturally falls to the inlet of the oiling mechanism, which is conducive to improving the oil coverage of the monofilament. Since the entire yarn path is simpler and the yarn friction is low, it can adapt to the production needs of higher speed. The yarn start-up operation is also simpler. It is only necessary to hang the yarn into the pig tail hook, and the yarn start-up time is shortened from more than one minute to less than 10 seconds. Attached Figure Description

[0020] The accompanying drawings are not intended to be drawn to scale. In the drawings, each identical or nearly identical component shown in the various figures may be denoted by the same reference numeral. For clarity, not every component is labeled in each figure. Embodiments of various aspects of the present invention will now be described by way of example and with reference to the accompanying drawings, wherein:

[0021] Figure 1 This is a schematic diagram of the existing technology for the oiling roller device in nylon 6 spinning.

[0022] Figure 2This is a schematic diagram of the structure of the low-friction oiling roller device for nylon 6 spinning shown in this utility model;

[0023] Figure 3 This is a schematic diagram of the mounting bracket shown in this utility model. Detailed Implementation

[0024] To better understand the technical content of this utility model, specific embodiments are provided below in conjunction with the accompanying drawings.

[0025] like Figure 1 As shown, in existing oiling roller devices, after passing through the guide bar, the yarn first passes through the ceramic ring for bundling, then through the yarn splitter for splitting, and then repeatedly winds around the surface of the guide before entering the oiling mechanism. Because the bundling point is relatively high and far from the oiling mechanism, the yarn bundle needs to be guided by the yarn splitter and guide multiple times before reaching the surface of the oiling mechanism. The friction accumulated from the multiple contacts of the yarn splitter and guide will scratch the surface of the single filament, producing a large number of fuzzy fibers. This not only causes uneven oiling but also affects the appearance quality and physical properties of the yarn.

[0026] Combination Figure 2 As shown, the first aspect of this utility model proposes a low-friction oiling roller device for spinning nylon 6, including a guide bar 11, at least one yarn guide component 30, and an oiling mechanism.

[0027] At least one guide bar 11 is mounted on the top of the support plate 10, and at least one thread guide component 30 is connected to the mounting frame 20, which is connected to the support plate 10. The cooled nylon 6 filament bundle passes through the corresponding thread guide component 30 along one side of the support plate 10 via the surface of the guide bar 11.

[0028] Furthermore, the oiling mechanism is located below the mounting bracket 20.

[0029] The thread guide component 30 is installed above the inlet of the oiling mechanism and serves as the gathering point for the nylon 6 filament bundle. There is no filament separator or guide between the thread guide component 30 and the inlet of the oiling mechanism. The mounting bracket 20 is configured to be detachably mounted on a predetermined area of ​​the support plate 10, making the position of the thread guide component 30 adjustable. The nylon 6 filament bundle that hangs down after being gathered by the thread guide component 30 can directly enter the inlet of the oiling mechanism.

[0030] Thus, the filament path via the guide bar 11 is very simple. It enters directly from the bundle point formed by the wire guide component 30 into the inlet of the oiling mechanism, and then is fed into the first hot roller (not shown in the figure, located at the outlet of the oiling mechanism). This constructs a very simple and low-friction filament path. By simplifying the path and reducing friction points, more uniform oiling, a significant reduction in fuzz, more stable roller tension, and a significant increase in the speed of filament growth are achieved.

[0031] In an optional embodiment, the thread guide component 30 includes a pigtail hook. Based on the structural characteristics of the pigtail hook, it includes a notch and a constraint hole through which the nylon 6 filament bundle can be easily placed into the constraint hole for threading. The constraint hole acts as a bundle-gathering point for the filament bundle, and the constraint hole has low resistance, which is beneficial for the thread-gathering operation.

[0032] Combination Figure 2 As shown, two guide rods 11 are provided on the top of the support plate 10, and two wire guide components 30 are provided on the mounting bracket 20. In this way, the wire bundles that naturally fall from the guide rods 11 can pass through the corresponding pigtail hooks to form a cluster point. The wire bundles that naturally fall from the cluster point can directly enter the oiling mechanism inlet. The entire wire path is short and has no complex bends or contacts. The friction of the wire bundles during movement is extremely low and the stress is uniform, which can adapt to the needs of high-speed production. While achieving better oiling effect, it also reduces the probability of damage to the wire bundle surface.

[0033] Combination Figure 2 As shown, the mounting bracket 20 is mounted horizontally to the surface of the support plate 10. This ensures that the two cable guide components 30 on the mounting bracket 20 are at the same height.

[0034] like Figure 3 As shown, each wire guide component 30 can adjust its installation position along the length of the mounting bracket 20.

[0035] In an optional embodiment, the mounting bracket 20 includes a first plate 201 and a second plate 202. A bracket 21 is connected to the second plate 202. The first plate 201 is mounted on the surface of the support plate 10 and its position on the surface of the support plate 10 can be changed by removing screws. The bracket 21 is mounted on the surface of the second plate 202 and its position on the surface of the second plate 202 can also be changed along the length direction of the second plate 202. A pig tail hook is mounted on the bracket 21.

[0036] Furthermore, the bracket 21 is also constructed in an L-shape, with the third plate 211 connected to the surface of the second plate 202, and the fourth plate 212 used to mount the pig tail hook.

[0037] Preferably, each guide member 30 is positioned directly below the guide bar 11. This allows the filament bundle hanging down from the guide bar 11 to be bundled together in the guide member 30 below.

[0038] In an optional embodiment, the oiling mechanism includes an oil pan 40, an oil lip, or an oil roller.

[0039] Combination Figure 2 As shown, the oiling mechanism includes an oil pan 40 and a thread guide roller 50 connected to the support plate 10. The thread guide roller 50 is located above one side of the oil pan 40. The nylon 6 filament bundle hanging from the gathering point passes around the oil pan 40 and the thread guide roller 50 in sequence, and the number of turns is more than two.

[0040] The axis of the oil tray 40 is located on one side of the midpoint of the line connecting the two thread guide components 30. In this way, the yarn strands hanging from the two pigtail hooks can wrap around the surface of the oil tray 40 from the same side.

[0041] In conjunction with the above embodiments, this utility model removes the original filament splitter and filament guide of the equipment, and replaces the ceramic ring with a pigtail hook to form a new bundle point. The bundle point is lower than that of the existing equipment, and the filament bundle naturally falls to the inlet of the oiling mechanism, which is conducive to improving the oil coverage of the monofilament. Since the entire filament path is simpler and the friction of the thread is lower, it can adapt to the production needs of higher speed. The filament head raising operation is also simpler. It is only necessary to hang the filament bundle into the pigtail hook, and the filament head raising time is shortened from more than one minute to less than 10 seconds.

[0042] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Those skilled in the art to which this invention pertains can make various modifications and refinements without departing from the spirit and scope of the present invention. Therefore, the scope of protection of this invention shall be determined by the claims.
