Abstract
Description
Technical Field
[0001] This specification relates to the field of spinning technology, and in particular to an adjustable guide mechanism for a steel platform. Background Technology
[0002] Currently, among civilian chemical fiber filaments, for polyester low-pore-count ultra-coarse denier monofilament FDY (Fully Drawn Yarn), the monofilament fineness generally exceeds 16D, such as 200D / 12f, where the monofilament fineness = 200 / 12 = 16.6. Twelve fiber monofilaments are combined to form a filament with a fineness of 200D. Due to its special rigidity and toughness, it is generally used to make home textiles, bag fabrics, tent fabrics, etc. If an irregular cross-section is added (such as flat, wavy flat, etc.), it can also be made into a stiff-haired variety of fleece, which has a considerable product premium.
[0003] In the production of civilian polyester filament, when the filament bundle exits the hot roller and enters the main network, the width of the bundle after being shaped and wound on the hot roller is generally 5cm to 10cm. This width then expands to 40cm to 60cm on the main network. From the main network, it enters the winding machine, where the width from the inner spindle to the outer spindle is generally 120cm to 160cm. This determines that when the filament bundle enters the winding machine from the main network, only the middle spindle enters the machine guide hook at a vertical angle, while the spindles at both ends enter at an angle. After entering the machine guide hook at an angle, the filament bundle enters the traverse guide, where it is moved back and forth to lay the bundle flat on the paper tube.
[0004] However, for ultra-coarse denier monofilaments with few pores, it is difficult to achieve symmetrical and integral shaping during winding. Severe tangling and asymmetrical front and back structures are prone to occur during yarn cake formation. Specifically, when the yarn is wound onto the bobbin, the yarn bundle is driven by a traversing guide, moving from one end of the yarn cake to the other. This allows a single yarn to be wound into a disc-shaped bobbin of a certain width through lateral movement on the paper tube. During this lateral movement at both ends, the yarn bundle deviates from the normal winding track and becomes noticeably tangled on the end face of the bobbin, resulting in a straight line – a phenomenon known as "tangling." In the production of polyester filament, tangling causes the FDY end face yarns to become misaligned and deviate from the normal track, affecting subsequent weaving and unwinding, and even causing breakage. This must be avoided as much as possible. Utility Model Content
[0005] The inventors discovered that the filaments entering the winding machine at both ends are at an angle. When the traverse guide moves the filaments at the angle to the left and right, it causes different tensions at the left and right ends of the filament cake. As a result, the filament cakes at the two ends of the winding machine are asymmetrically formed, making it easier for filaments to come off the machine.
[0006] In view of the shortcomings of the prior art, one object of this specification is to provide an adjustable guide mechanism for steel platform that can form FDY yarn cakes with a small number of holes and ultra-coarse denier filaments symmetrically on both sides without yarn tangling.
[0007] To achieve the above objectives, this specification provides an adjustable wire guide mechanism for a steel platform. The wire guide mechanism is installed at the opening of the steel platform. A hot roller and a web feeder are located above the steel platform, and a winding machine is located below the steel platform. A winding guide hook is located above the winding machine. The wire guide mechanism includes:
[0008] A mounting plate is fixedly installed at the opening of a steel platform, and the mounting plate is provided with a sliding groove;
[0009] A movable wire guide hook is slidably mounted on the mounting plate. A slider is fixedly connected to the movable wire guide hook, and the slider is disposed in the sliding groove. In the first horizontal direction, the size of the slider is smaller than the size of the sliding groove, so that the movable wire guide hook can slide in the first horizontal direction. The movable wire guide hook and the winding machine wire guide hook correspond one-to-one in the vertical direction. The wire bundle passing through the hot roller and the network device passes through the movable wire guide hook and the winding wire guide hook in sequence and enters the winding machine. The wire bundle passing through the movable wire guide hook enters the winding wire guide hook vertically.
[0010] In a preferred embodiment, the plurality of sliding grooves are arranged at intervals in the first horizontal direction, and the plurality of movable guide wire hooks are respectively slidably disposed in the plurality of sliding grooves.
[0011] In a preferred embodiment, the distance between any two adjacent sliding grooves is equal everywhere.
[0012] In a preferred embodiment, the movable guide hook and the slider are fixedly connected by fasteners.
[0013] In a preferred embodiment, a portion of the fastener protrudes from the top surface of the mounting plate.
[0014] In a preferred embodiment, the movable guide hook includes a mounting portion and a guide portion, wherein the mounting portion is linear and the guide portion is a notched annular shape.
[0015] In a preferred embodiment, the mounting portion extends along a second horizontal direction and passes through the sliding groove, the second horizontal direction being perpendicular to the first horizontal direction.
[0016] In a preferred embodiment, the plurality of guide wire portions are located on the same side of the mounting plate in the second horizontal direction.
[0017] In a preferred embodiment, there are two mounting plates, located at both ends of the opening of the steel platform in the second horizontal direction; the guide wire portions of the movable guide wire hooks on the two mounting plates are arranged opposite to each other.
[0018] In a preferred embodiment, the two mounting plates and the movable guide hooks on the mounting plates are symmetrically arranged in the second horizontal direction. Beneficial effects
[0019] The adjustable wire guide mechanism of the steel platform provided in this embodiment uses a mounting plate fixedly installed at the opening of the steel platform. A movable wire guide hook is slidably installed on the mounting plate, and a slider is fixedly connected to the movable wire guide hook. The slider can slide in a sliding groove along a first horizontal direction, thereby driving the movable wire guide hook to slide in the first horizontal direction. The position of the movable wire guide hook in the first horizontal direction is variable, allowing the wire path entering the winding machine to enter the winding machine at a set angle after turning the angle. This ensures that the angle of the wire path on the winding wire guide hook is consistent when the wire bundle moves left and right. The movable wire guide hook can change the angle of the wire bundle to be perpendicular to the winding wire guide hook, ensuring that the wire bundle spindle position entering the winding machine is at the same vertical angle. This allows for the formation of FDY wire cakes with low-hole-count, ultra-coarse denier monofilaments, resulting in symmetrical wire cakes with no wire tripping.

[0033] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.
[0034] It should be noted that when an element is referred to as being "set on" another element, it can be directly on the other element or may be interposed with another element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or may be interposed with another element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementations.
[0035] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.
[0036] The inventors discovered that for ultra-coarse denier monofilaments with few holes, during the winding process, due to the small number of holes and coarse fineness, the contact area between the filaments is small and the friction points are few when the filament bundle is stacked on the paper tube. During high-speed winding, as the height of the stacked filament layers increases, the outer layer will gradually slip relative to the inner layer. If the tension of the filaments stacked on the left and right sides of the filament cake is different, it will cause asymmetry in the formation of the inner and outer sides of the filaments. This will affect the unwinding tension fluctuation of the filament cake during later processing, and in severe cases, it will cause filament breakage.
[0037] In conventional civilian spinning processes, the angle at which the yarn enters the winding machine 5 from above is different. Generally, the yarn bundle comes down from the middle of the winding machine 5. Therefore, for the middle spindle of the winding machine 5, the yarn bundle enters the winding guide hook 6 vertically, while for the spindles on both sides of the winding machine 5, the yarn bundle enters at an inclined angle. Figure 2 As shown. After the filament enters the winding guide hook 6 at an angle, it then enters the traversing guide 7. As the traversing guide 7 moves the filament back and forth on its fork blades, when the filament travels to one side of the tilt angle on the filament cake, as... Figure 1 As shown on the left, the entire filament path forms an acute angle α1 at the winding guide hook 6, at which point the filament tension is high; as Figure 1 As shown on the right, when the filament bundle on the winding guide hook 6 forms an obtuse angle α2, the filament bundle tension is small; this causes different tensions on the left and right sides of the filament bundle in the rolled filament cake 8, ultimately resulting in asymmetrical filament cake formation. Usually, this asymmetry will not affect the use of filament cakes of conventional specifications, but its impact on the coarse denier monofilament specification with fewer holes that this application aims to address is not negligible.
[0038] Therefore, please refer to Figures 3 to 7 This application provides an adjustable wire guide mechanism 1 for a steel platform, which can be added to a steel platform 2 in the prior art. For example... Figure 4 and Figure 5 As shown, the wire guide mechanism 1 is installed at the opening 21 of the steel platform 2. A hot roller 3 and a netter 4 are located above the steel platform 2, and a winding machine 5 is located below the steel platform 2. A winding guide hook 6 is located above the winding machine 5. The steel platform 2, hot roller 3, netter 4, winding machine 5, and winding guide hook 6 can all be of conventional structures, which will not be described in detail here. A pressure roller 9 may also be located above the winding machine 5.
[0039] like Figure 6 and Figure 7 As shown, the wire guiding mechanism 1 includes a mounting plate 11 and a movable wire guide hook 12. The mounting plate 11 is fixedly installed at the opening 21 of the steel platform 2. The mounting plate 11 is provided with a sliding groove 111. The movable wire guide hook 12 is slidably installed on the mounting plate 11. The movable wire guide hook 12 is fixedly connected to a slider 13, which is disposed within the sliding groove 111. In the first horizontal direction X, the size of the slider 13 is smaller than the size of the sliding groove 111, allowing the movable wire guide hook 12 to slide in the first horizontal direction X. The movable wire guide hook 12 corresponds one-to-one with the wire guide hook of the winding machine 5 in the vertical direction. The wire bundle passing through the hot roller 3 and the networker 4 passes sequentially through the movable wire guide hook 12 and the winding wire guide hook 6 into the winding machine 5. The wire bundle passing through the movable wire guide hook 12 enters the winding wire guide hook 6 vertically.
[0040] The adjustable wire guide mechanism 1 of the steel platform provided in this embodiment has a mounting plate 11 fixedly installed at the opening 21 of the steel platform 2. A movable wire guide hook 12 is slidably installed on the mounting plate 11. The movable wire guide hook 12 is fixedly connected to a slider 13, which can slide in the sliding groove 111 along the first horizontal direction X, thereby driving the movable wire guide hook 12 to slide in the first horizontal direction X. The position of the movable wire guide hook 12 in the first horizontal direction X is variable. After the wire enters the winding machine 5, it turns at a set angle and enters the winding machine 5, ensuring that the angle of the wire on the winding wire guide hook 6 is consistent when the wire bundle moves left and right. Figure 3 As shown. Figure 4 As shown, the movable guide hook 12 can change the angle of the filament bundle to be perpendicular to the winding guide hook 6, ensuring that the filament bundle spindles entering the winding machine 5 are all at the same vertical angle, so that FDY filament cakes with a small number of holes and ultra-coarse denier monofilaments can be formed, the filament cakes are symmetrical on both sides, and there is no filament tripping.
[0041] In this embodiment, a plurality of sliding grooves 111 are arranged at intervals in the first horizontal direction X, and a plurality of movable wire hooks 12 are respectively slidably disposed in the plurality of sliding grooves 111. The appropriate number of sliding grooves 111 and movable wire hooks 12 can be selected according to the required number of spindle positions.
[0042] Preferably, the distance between any two adjacent sliding grooves 111 is equal everywhere. Of course, in other embodiments, the distance between two adjacent sliding grooves 111 at different positions can be adjusted as needed.
[0043] like Figure 7As shown, the movable guide hook 12 and the slider 13 are fixedly connected by a fastener 14. The fastener 14 can be a component that is easy to disassemble and install, such as a screw. Specifically, some of the fasteners 14 protrude from the top surface of the mounting plate 11 to facilitate identification of the position of the movable guide hook 12.
[0044] In this embodiment, the movable wire guide hook 12 includes a mounting portion 121 and a wire guide portion 122. The mounting portion 121 is linear. The wire guide portion 122 is a notched annular shape, with the notch and central hole allowing the wire bundle to pass through.
[0045] Specifically, the mounting portion 121 extends along the second horizontal direction Y and passes through the sliding groove 111 to ensure a stable connection between the movable guide hook 12 and the mounting plate 11. The second horizontal direction Y is perpendicular to the first horizontal direction X, and both the first horizontal direction X and the second horizontal direction Y are parallel to the horizontal plane. Preferably, a plurality of the guide portions 122 are located on the same side of the mounting plate 11 in the second horizontal direction Y.
[0046] To improve production efficiency, such as Figure 5 As shown, there are two mounting plates 11, located at the two ends of the opening 21 of the steel platform 2 in the second horizontal direction Y. The guide portions 122 of the movable guide hooks 12 on the two mounting plates 11 are arranged opposite to each other, and each mounting plate 11 corresponds to one winding machine 5. The winding directions of the two winding machines 5 are opposite.
[0047] Preferably, the two mounting plates 11 and the movable guide hooks 12 on the mounting plates 11 are symmetrically arranged in the second horizontal direction Y.
[0048] In one specific embodiment, the filament bundle shaped by the hot roller 3 passes through the networker 4, where it is wound and dotted before entering the movable guide hook 12 set on the steel platform 2, and then enters the winding guide hook 6 above the winding machine 5. After entering the winding guide hook 6, the filament bundle is traversed and pulled by the rotary blade type transverse guide 7, which lays the filament flat on the paper tube. The transverse guide 7 is formed by two stacked rotary blade components, which run in opposite directions. When the upper rotary blade component pulls the filament bundle from one side around the forming arc plate to the other side, the lower rotary blade component pulls the filament bundle back from the opposite direction.
