Description

Technical Field

[0001] The present application relates to the technical field of wire drawing equipment, and in particular to a wire guide limiting mechanism for wire drawing equipment. Background Art

[0002] The production of composite ES fibers requires a series of processes including extrusion molding, spinning, drawing, thread compounding, stretching and curling, and heat setting. The wire drawing equipment is a device used to guide the transmission of the threads during the ES fiber production process. It can adjust the tension and transmission rate of the threads during transmission, so that each thread can be stably converged at the rear end and smoothly bundled and compounded, reducing the occurrence of thread entanglement.

[0003] Reference Figure 1 The current prior art discloses a wire drawing device 9, including a device assembly and a plurality of guide rollers 92 arranged on the device assembly, wherein the guide rollers 92 are arranged on the side of the device assembly for winding the wires in sequence and in an orderly manner; the guide rollers 92 are slidably arranged on the device assembly through a sliding structure, and the distance of the wires between the two guide rollers 92 and the contact position between the wires and the guide rollers 92 can be adjusted by adjusting the position of the guide rollers 92, thereby changing the tension of the wires.

[0004] However, the position adjustment between the guide roller and the equipment assembly is automatically controlled by the control system inside the equipment assembly. However, due to the large outer diameter of the guide roller, a slight position change between the guide roller and the equipment assembly will cause a large change in the tension of the wire. It is often difficult to adjust to the appropriate position in one operation. It is difficult for the operator to operate and requires a high level of technical proficiency, which needs to be improved. Utility Model Content

[0033] The following is combined with Figure 2-5 This application is described in further detail.

[0034] Embodiment 1:

[0035] The embodiment of the present application discloses a wire guide limiting mechanism for a wire drawing device, which can be installed on the wire drawing device 9 and used to quickly adjust the tension of the wire.

[0036] Reference Figure 2 A wire guide limiting mechanism for a wire drawing device comprises a fixed rod 1, a wire guide rod 2 and a wire stop rod 3; wherein the fixed rod 1 is a cylindrical rod, a threaded portion 11 is provided at the end of the fixed rod 1, and a first stopper 5 is threadedly sleeved on the threaded portion 11. A threaded hole 91 is provided on the side of the wire drawing device 9, and the fixed rod 1 can be fixedly connected to the wire drawing device 9 by threading the threaded portion 11 into the threaded hole 91 and then rotating the first stopper 5 to abut against the wire drawing device 9. It should be noted that the first stopper 5 in this embodiment is a hexagonal nut.

[0037] A connecting plate 4 is sleeved on the middle part of the fixed rod 1. In this embodiment, the connecting plate 4 is welded and fixed to the fixed rod 1. The wire guide rod 2 is fixedly connected to the connecting plate 4 and eccentrically arranged with the fixed rod 1, and the central axis of the wire guide rod 2 remains parallel to the central axis of the fixed rod 1.

[0038] Reference Figure 3 A plurality of guide rollers 92 are fixedly installed on the side of the wire drawing device 9, and the wire can be wound around each guide roller 92 in sequence when the wire drawing device 9 is pulled and moved; after installation, the wire guide limiting mechanism in this embodiment can be located between two adjacent guide rollers 92, and the wire guide rod 2 can abut against the wire, and by rotating the fixed rod 1 to adjust the relative position of the wire guide rod 2 and the fixed rod 1, the tension of the wire from the wire guide rod 2 can be easily changed, thereby reducing the operating difficulty of the operator.

[0039] Back to Figure 2 The ends of the screw stop rod 3 are fixed with connecting sockets 31, and the connecting sockets 31 are provided with plug-in holes 311. The inner diameter of the plug-in holes 311 is equal to the outer diameter of the fixed rod 1, so that the fixed rod 1 can match and pass through the plug-in holes 311, thereby realizing the axial movement of the screw stop rod 3 along the fixed rod 1; it should be noted that, in this embodiment, the central axis of the screw stop rod 3 can be kept perpendicular to the central axis of the fixed rod 1.

[0040] The outer side of the connecting socket 31 is threadedly connected with a locking piece 32. The locking piece 32 in this embodiment is a bolt. The locking piece 32 can be inserted into the plug hole 311 and abut against the fixed rod 1 to limit the position, thereby realizing the positioning of the screw stop rod 3 along the axial direction of the fixed rod 1.

[0041] In addition, there are two wire blocking rods 3, which are spaced apart to form a limiting space for limiting the pulling position of the wire. After the wire is in contact with the fixed rod 1, the two wire blocking rods 3 respectively block the two sides of the wire, thereby limiting the position of the wire when it is pulled and moved by force, which is beneficial for the various wires to converge stably at the rear end and be smoothly bundled and compounded, thereby reducing the occurrence of wire entanglement.

[0042] The outer peripheral surface of the wire guide rod 2 and the outer peripheral surface of the wire blocking rod 3 are provided with a hydrophilic coating (not shown in the figure). The setting of the hydrophilic coating can quickly disperse moisture on the surface of the wire guide rod 2 and the wire blocking rod 3, keep the surface of the rod body clean, and improve the waterproof and anti-fouling capabilities; at the same time, it can also enable the wire guide rod 2 and the wire blocking rod 3 to maintain good wear resistance.

[0043] The implementation principle of Example 1 of the present application is:

[0044] When it is necessary to adjust the tension of the wire between the two guide rollers 92, the operator rotates the first stopper 5 to make it leave the surface of the wire drawing device 9, and can conveniently rotate the fixed rod 1 to adjust the position of the wire guide rod 2, thereby changing the contact position between the wire guide rod 2 and the wire and changing the tension of the wire guide rod 2, so as to facilitate stable guidance and transportation of the wire.

[0045] Embodiment 2:

[0046] The embodiment of the present application discloses a wire guide limiting mechanism for a wire pulling device.

[0047] Reference Figure 4 The embodiment of the present application discloses a wire guide limiting mechanism for a wire pulling device, and the remaining components are the same as those in the embodiment 1, and are not described one by one here; the difference from the embodiment 1 is that the connecting plate 4 in the present embodiment is sleeved on the threaded portion 11 of the fixed rod 1, and the threaded portion 11 is threadedly connected to two second stop members 6, and by making the two second stop members 6 respectively abut against the two opposite side surfaces of the connecting plate 4, the axial position and angular position of the connecting plate 4 on the fixed rod 1 can be limited, thereby further improving the convenience of adjusting the wire tension.

[0048] In addition, the first stopper 5 in this embodiment includes a screw sleeve portion 51 and a handle portion 52, and the handle portion 52 is integrally formed on the outer peripheral surface of the screw sleeve portion 51; wherein the screw sleeve portion 51 is used for threaded connection with the threaded portion 11, and the handle portion 52 is used for the operator to hold it. The thickness of the handle portion 52 is less than the axial length of the screw sleeve portion 51. When the first stopper 5 is pressed against and locked on the wire drawing device 9, a gap can be formed between the handle portion 52 and the side of the wire drawing device 9, so that the operator can force the first stopper 5 to rotate through the handle portion 52, and the wire guide rod 2 can be quickly adjusted without the help of auxiliary tools.

[0049] It should be noted here that the structure of the second stop member 6 is the same as the specific structure of the first stop member 5, and the only difference is the installation position, which will not be elaborated here; in addition, the locking member 32 in this embodiment uses a butterfly bolt, which can facilitate the operator to quickly adjust the relative position of the screw stop rod 3 to the fixed rod 1 without the aid of auxiliary tools.

[0050] The implementation principle of Example 2 of the present application is:

[0051] When it is necessary to adjust the tension of the wire between the two guide rollers 92, the operator can conveniently rotate the first stop member 5 using the handle portion 52 of the first stop member 5, so that the fixed rod 1 can rotate relative to the wire pulling device 9, thereby changing the position of the wire guide rod 2; or the operator can conveniently rotate the second stop member 6 using the handle portion 52 of the second stop member 6, so that the connecting plate 4 can rotate relative to the wire guide rod 2, and the position of the wire guide rod 2 can also be changed to achieve rapid adjustment of the wire tension.

[0052] Embodiment 3:

[0053] The embodiment of the present application discloses a wire guide limiting mechanism for a wire pulling device.

[0054] Reference Figure 5 , a wire guide limiting mechanism for a wire pulling device disclosed in an embodiment of the present application, the remaining components are the same as those in Example 1, and are not described one by one here; the difference from Example 1 is that, in this embodiment, the outer peripheral surface of the first stop member 5 is integrally formed with an extension portion 53, and the extension portion 53 is located at the end of the first stop member 5 away from the traction device; the side of the connecting plate 4 close to the traction device is integrally formed with an annular convex portion 41, the annular convex portion 41 can be arranged opposite to the extension portion 53, and a positioning structure 7 is provided between the annular convex portion 41 and the extension portion 53, and the positioning structure 7 can maintain the angle positioning of the annular convex portion 41 and the extension portion 53 when they are in contact.

[0055] Specifically, the positioning structure 7 includes an outer peripheral tooth ring 71 and an annular tooth groove 72. In this embodiment, the outer peripheral tooth ring 71 is integrally formed on the side of the extension portion 53 close to the annular protrusion 41, and the annular tooth groove 72 is opened on the side of the annular protrusion 41 close to the outer edge; when the extension portion 53 abuts against the annular protrusion 41, the outer peripheral tooth ring 71 can match and bite with the annular tooth groove 72, thereby limiting the rotation of the connecting plate 4. It can be understood that in another feasible embodiment, the outer peripheral tooth ring 71 can be integrally formed on the side of the annular protrusion 41 close to the extension portion 53, and the annular tooth groove 72 can be correspondingly opened on the side of the extension portion 53 close to the annular protrusion 41.

[0056] In addition, the fixed rod 1 is provided with an elastic member 8, and the elastic member 8 is a spring. One end of the elastic member 8 abuts against the connecting plate 4, and the other end abuts against the connecting seat 31 of the wire stop rod 3 adjacent to the connecting plate 4; the elastic member 8 can always generate an elastic force acting on the connecting plate 4, thereby keeping the peripheral tooth ring 71 and the annular tooth groove 72 in contact and in a bite state, so as to achieve the angular positioning of the connecting plate 4, thereby keeping the wire guide rod 2 fixed.

[0057] The implementation principle of Example 3 of the present application is:

[0058] When it is necessary to adjust the tension of the wire between the two guide rollers 92, by forcing the connecting plate 4 to move away from the first stop member 5, the peripheral tooth ring 71 can be disengaged from the annular tooth groove 72, and the operator can easily rotate the connecting plate 4 to adjust the position of the wire guide rod 2, thereby changing the tension of the wire; after the angle adjustment of the connecting plate 4 is completed, the external force is removed, and the elastic force of the elastic member 8 acting on the connecting plate 4 can force the peripheral tooth ring 71 and the annular tooth groove 72 to re-engage and limit, thereby achieving the fixing of the position of the connecting plate 4 and the wire guide rod 2.

[0059] The above are preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
