Abstract
Description
Technical Field
[0001] This application relates to the field of winding machine equipment technology, and in particular to a monofilament positioning component. Background Technology
[0002] In the field of fiber drawing production, the drawing and winding device is the core equipment that ensures efficient and orderly winding of drawn monofilaments, playing an indispensable role in the processing and manufacturing of many materials such as chemical fibers and metal wires. Its performance directly affects several key indicators, including production efficiency, product quality, and production costs.
[0003] Currently, to improve winding efficiency, existing wire drawing and winding devices generally adopt a design integrating multiple winding components. Each winding component is equipped with a corresponding monofilament positioning component. One end of this monofilament positioning component is connected to a positioning bracket via a detachable fixed connection, while the other end extends to the center of the steel collar of the winding component. At the end extending to the steel collar, a horizontally arranged bearing is installed, and the outer surface of the bearing has grooves to guide the direction of the wire. This design does indeed guide the wire to a certain extent, allowing it to be wound along a predetermined path.
[0004] However, existing monofilament positioning components still have significant drawbacks: Firstly, the bottom of the existing monofilament positioning component is fixedly connected to the positioning bracket, causing it to always extend onto the surface of the steel collar. When the yarn on the take-up spool is full, the operator must first remove the monofilament positioning component from the positioning bracket before the full take-up spool can be easily removed. After a new empty take-up spool is installed, the monofilament positioning component needs to be reinstalled on the positioning bracket. This disassembly and installation process is not only cumbersome but also time-consuming and labor-intensive, greatly increasing auxiliary time in the production process and reducing production efficiency. Especially in large-scale, continuous production environments, such frequent disassembly and installation operations can seriously affect the overall operating rhythm of the production line and increase production costs. On the other hand, the horizontally positioned bearings in existing monofilament positioning assemblies have significant drawbacks in guiding the filament. During winding, the filament sags due to gravity. Although the filament is pulled closer and adheres to the bearing groove under centrifugal force and friction when the winding drum rotates at high speed, the filament continues to be fed due to inertia when the drum stops, and sags further under gravity, thus detaching from the bearing groove. Each time winding restarts, operators need to spend extra time and effort to reposition the filament back into the bearing groove, reducing production efficiency.
[0005] In summary, the existing single-filament positioning component settings in wire drawing and winding devices have many shortcomings, severely hindering the development of the wire drawing industry. Therefore, it is necessary to optimize and improve the structure and setting of the single-filament positioning component to enhance the performance and production efficiency of wire drawing and winding devices. Utility Model Content
[0006] The purpose of this application is to provide a monofilament positioning component to solve the technical problems existing in the prior art, such as the need for frequent disassembly and assembly of the positioning component when changing the winding drum due to the fixed connection between the monofilament positioning component and the positioning bracket, which is time-consuming and labor-intensive, and the easy for the filament to fall off the groove due to inertia and gravity when the horizontally arranged bearing stops, which requires repositioning the filament every time it is rewound, thus reducing production efficiency and winding quality.
[0007] The embodiments of this application can be implemented through the following technical solutions:
[0008] A single-wire positioning assembly includes a wire bearing, a positioning bracket, a positioning base, and a limiting component. The inner side of the positioning base is fixedly connected to the frame, and one end of the positioning bracket is hinged to the positioning base through the limiting component and limited to the outer side of the positioning base.
[0009] One end of the limiting component passes through the positioning bracket and abuts against the positioning base under the action of elastic force, while the other end of the positioning bracket is rotatably connected to the cable bearing.
[0010] Furthermore, the positioning base is fixedly connected to the outside of the first frame, which is a hollow frame.
[0011] The limiting assembly includes a limiting rod and an elastic element. One end of the limiting rod passes through the positioning bracket, the positioning base, and the first frame in sequence, and is connected to the elastic element located in the hollow cavity of the first frame. One end of the elastic element away from the positioning bracket is fixedly connected to the limiting rod, and the other end abuts against the inner wall of the first frame.
[0012] Furthermore, the outer side of the positioning base is provided with a limiting groove. The limiting groove has at least two extreme positions with the limiting component as the fulcrum. Pulling the hinge end of the positioning bracket can make it rotate at different extreme positions of the limiting groove, and under the elastic action of the limiting component, it is limited to be located in the limiting groove of the positioning base.
[0013] Furthermore, the axial direction of the positioning bracket located directly in front of the winding drum is defined as the Z-axis direction, and the axial direction of the winding transmission assembly is defined as the Y-axis direction. The limiting groove extends through the Z-axis, and a first hinge hole is provided in the middle of the limiting groove. A milled surface is provided on the side of the positioning bracket hinge end facing away from the positioning base. A second hinge hole extending through the Y-axis is provided on the milled surface. The limiting rod passes through the second hinge hole and engages with the first hinge hole.
[0014] Furthermore, with the extension direction of the first frame defined as the X-axis direction, the positioning bracket includes a column and a plate. The top of the column is provided with a mounting groove that runs through the Y direction and a first connecting hole that runs through the X direction. Correspondingly, the bottom of the plate is provided with a second connecting hole that mates with the first connecting hole. The top of the mounting groove is open, and the bottom of the plate is rotatably connected to the mounting groove and fixed in position by fasteners.
[0015] Furthermore, a third connecting hole is provided on the top of the plate, and the cable bearing is connected to the third connecting hole through a rotating shaft. The rotating shaft includes a locking nut and a shaft rod. One end of the shaft rod is engaged with the inner ring of the cable bearing for limiting, and the other end passes through the third connecting hole and is locked by the locking nut.
[0016] Furthermore, the plate has a bending angle, with the top of the plate bent obliquely upwards, and the angle between the bending direction and the axis of the column is an acute angle.
[0017] Furthermore, the wiring bearing is vertically connected to the top side of the plate, and the axis of the wiring bearing has an inclined angle relative to the XY plane.
[0018] Furthermore, along the circumferential direction of the wiring bearing, the radial dimension of the middle part of the wiring bearing is smaller than the radial dimensions of its two ends, so as to form a wiring groove on the outer surface of the wiring bearing.
[0019] The monofilament positioning component provided in the embodiments of this application has at least the following beneficial effects:
[0020] This application utilizes a flexible abutment limiting component, allowing the positioning bracket to rotate flexibly around the positioning base to adjust its position. The elastic abutment design ensures that the positioning bracket is stably limited during operation, preventing displacement caused by vibration, and also allows for quick position switching by manual pulling. This means that when changing the take-up spool, there is no need to disassemble the monofilament positioning component; simply rotating and adjusting its position allows for easy disassembly. This application offers advantages such as high operational flexibility, strong positioning stability, and good practicality.
[0021] This application uses a combination of a column and a plate, which facilitates positioning during installation. The installation position and angle of the cable guide bearing can be adjusted by rotating the connection between the plate and the column. In this application, the top of the plate is bent upwards at an angle, and the cable guide bearing is vertically connected to its top side with its axis inclined relative to the XY plane. This allows the wire to be guided diagonally downwards from above, effectively preventing the wire from detaching from the groove due to inertia and gravity when the winding drum stops, reducing the hassle of repositioning the wire each time it is rewound.

Detailed Implementation
[0028] The present application will now be further described based on preferred embodiments and with reference to the accompanying drawings.
[0029] Furthermore, for ease of understanding, various components on the drawings have been enlarged or reduced, but this is not intended to limit the scope of protection of this application.
[0030] Singular forms of words also include plural meanings, and vice versa.
[0031] In the description of the embodiments of this application, it should be noted that if terms such as "upper," "lower," "inner," or "outer" are used to indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product of this application is in use, they are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on this application.

[0032] The vocabulary used in this specification is for illustrative purposes and is not intended to limit the scope of this application. It should also be noted that, unless otherwise expressly specified and limited, the terms "set," "connected," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection, a direct connection, or an indirect connection via an intermediate medium; or they can refer to the internal communication between two components. Those skilled in the art will understand the specific meaning of these terms in this application.
[0033] like Figures 1 to 4 As shown, a single-wire positioning assembly includes a wire bearing 71, a positioning bracket 72, a positioning base 73, and a limiting component 74. The inner side of the positioning base 73 is fixedly connected to the frame S. One end of the positioning bracket 72 is hinged to the positioning base 73 via the limiting component 74 and is limited to the outer side of the positioning base 73. One end of the limiting component 74 passes through the positioning bracket 72 and abuts against the positioning base 73 under the action of elastic force, allowing the positioning bracket 72 to rotate flexibly around the limiting component 74 to adjust its position. At the same time, the elastic abutment ensures that it is stably limited during operation and avoids loosening due to vibration or other factors.
[0034] Furthermore, the other end of the positioning bracket 72 is rotatably connected to the wiring bearing 71. The outer circumferential surface of the wiring bearing 71 is provided with a wiring groove for wiring. The wiring groove is used to guide the direction of the monofilament and prevent the wire from deviating or slipping during transmission.
[0035] Compared to existing technologies, this application achieves flexible hinge connection between the positioning bracket 72 and the positioning base 73 through the limiting component 74. When changing the take-up spool, the positioning bracket 72 can be easily replaced by rotating it around the limiting component 74 to adjust the angle. There is no need to disassemble the positioning component, which greatly improves the operating efficiency, reduces component wear, and effectively reduces equipment maintenance costs and downtime.
[0036] For ease of description, using Figure 1 For reference, the axial direction of the winding drive assembly 4 is defined as the Y-axis direction, the extension direction of the first frame S1 is defined as the X-axis direction, and the axial direction of the positioning bracket 72 located directly in front of the winding drum 1 is defined as the Z-axis direction. The three axes are perpendicular to each other.
[0037] In some preferred embodiments, such as Figure 1 As shown, the steel collar 5 is fixedly connected to the first frame S1 of the frame S. One end of the winding transmission assembly 4 is fixedly connected to the frame S through a bearing seat, and the other end is connected to the winding drum 1. Under the action of the motor, the winding transmission assembly 4 drives the winding drum 1 to rotate. The wire passes through the guide provided on the frame S and winds onto the winding drum 1 through the wire routing groove of the wire routing bearing 71.
[0038] In some preferred embodiments, such as Figure 3 As shown, the positioning base 73 is fixedly connected to the outside of the first frame S1, which is a hollow frame. The limiting component 74 includes a limiting rod 741 and an elastic element 742. One end of the limiting rod 741 passes through the positioning bracket 72, the positioning base 73, and the first frame S1 in sequence, and is connected to the elastic element 742 located in the hollow cavity of the first frame S1. The end of the elastic element 742 away from the positioning bracket 72 is fixedly connected to the limiting rod 741, and the other end abuts against the inner wall of the first frame S1. Preferably, the elastic element 742 is a high elastic modulus compression spring. When the positioning bracket 72 rotates around the limiting rod 741, the elastic element 742 can provide a constant restoring force along the Y-axis, ensuring that it can accurately reset and lock along the Y-axis after switching different positions of the positioning base 73, realizing the dual functions of dynamic limiting and static stabilization in the Y-axis.
[0039] In some preferred embodiments, a limiting groove 731 is provided on the outer side of the positioning base 73. The limiting groove 731 has at least two extreme positions with the limiting component 74 as the fulcrum. Pulling the hinge end of the positioning bracket 72 allows it to rotate flexibly at different extreme positions of the limiting groove 731, and under the elastic action of the limiting component 74, it is limited to be located within the limiting groove 731 of the positioning base 73, thereby ensuring that the positioning bracket 72 will not loosen or shift during operation.
[0040] Preferably, the limiting groove 731 of the positioning base 73 is adapted to the outer surface contour of the positioning bracket 72 to improve the stability and reliability of the limiting.
[0041] In some preferred embodiments, such as Figure 4 As shown, one side of the positioning base 73 is fixedly connected to the first frame S1, and the other side is provided with a limiting groove 731 that runs through the Z direction. The two extreme positions of the limiting groove 731 are symmetrically distributed in opposite directions at 180°, forming a straight-opposite extreme work position. The middle of the limiting groove 731 is provided with a first hinge hole 732. The positioning bracket 72 is hinged to the first hinge hole 732 through a limiting rod 741. Under the action of external force, the positioning bracket 72 can be pulled to rotate 180° with its hinge point as the fulcrum and perform limiting.
[0042] In some preferred embodiments, to enhance the stability of the limiting position, the side of the hinge end of the positioning bracket 72 facing away from the positioning base 73 is provided with a milled surface 7211. A second hinge hole 7212 is provided on the milled surface 7211, which runs through the Y-axis. The limiting rod 741 passes through the second hinge hole 7212 and engages with the first hinge hole 732.
[0043] In some preferred embodiments, the positioning base 73 is detachably fixedly connected to the first frame S1. Threaded connection holes 733 are provided on both sides of the limiting groove 731. Bolts pass through the threaded connection holes 733 to connect the positioning base 73 to the first frame S1, thereby increasing the stability of the connection and facilitating disassembly.
[0044] In some preferred embodiments, such as Figure 4 The positioning bracket 72 includes a column 721 and a plate 722. The second hinge hole 7212 is disposed at the bottom of the column 721. The top of the column 721 has a mounting groove 7213 extending along the Y direction and a first connecting hole 7214 extending along the X direction. Correspondingly, the bottom of the plate 722 has a second connecting hole 7222 extending along the X direction. The top of the mounting groove 7213 is open. The bottom of the plate 722 is installed in the mounting groove 7213. The first connecting hole 7214 corresponds to the second connecting hole 7222. The connection position is fixed by fasteners such as bolts and nuts that cooperate with each other, so as to realize the rotational engagement between the two and the fixed connection by fasteners.
[0045] In some preferred embodiments, the top of the plate 722 is provided with a third connecting hole 7221, and the cable bearing 71 is connected to the third connecting hole 7221 through a rotating shaft 75. Preferably, the rotating shaft 75 includes a locking nut 751 and a shaft 752. One end of the shaft 752 is provided with a limiting structure for cooperating and limiting the inner ring of the cable bearing 71, and the other end passes through the third connecting hole 7221 and is locked by the locking nut 751.
[0046] It should be noted that the reason for adopting the form of column 721 and plate 722 is to facilitate positioning during installation, and the installation position and angle of the cable bearing 71 can be adjusted by rotating the connection position of plate 722 and column 721.
[0047] In some preferred embodiments, the plate 722 has a bending angle, with the top of the plate 722 bent obliquely upwards. The angle between the bending direction and the axis of the column 721 is an acute angle. The thread guide bearing 71 is vertically connected to the top side of the plate 722, and the axis of the thread guide bearing 71 is inclined relative to the XY plane. This allows the thread to be guided obliquely downwards from above, effectively avoiding the problem that the thread is easily dislodged from the groove due to inertia and gravity when the winding drum stops due to the horizontal arrangement of the thread guide bearing 71, requiring repositioning of the thread each time it is rewound.
[0048] In some preferred embodiments, along the circumferential direction of the wiring bearing 71, the radial dimension of the middle part of the wiring bearing 71 is smaller than the radial dimensions of its two ends, so as to form a wiring groove on the outer surface of the wiring bearing 71. This allows the wire to be confined to the outer surface of the wiring bearing 71 through the wiring groove for wiring, and during the wiring process, the wiring bearing 71 can also be driven to rotate around its axis, reducing frictional resistance and reducing the wear of the wire during the wiring process.
[0049] The specific embodiments of this application have been described in detail above. For those skilled in the art, several improvements and modifications can be made to this application without departing from the principle of this application, and these improvements and modifications also fall within the protection scope of the claims of this application.
