[0002] High-speed braiding machines on the market are generally composed of a pay-off mechanism, a braiding mechanism and a take-up mechanism. First, each initial wire is supplied to the braiding mechanism through the pay-off mechanism, and the multiple strands of wire are braided under the action of the braiding mechanism. After being braided into one, the wire is pulled to the take-up mechanism and wound around the take-up mechanism.

DETAILED DESCRIPTION

[0031] The following is combined with Figure 1-4 This application is described in further detail.

[0032] The present application embodiment discloses a high-speed braiding machine wire taking-up device. Figure 1 A high-speed braiding machine wire taking-up device comprises a casing 1, wherein a wire-releasing mechanism and a braiding mechanism (not shown in the drawings) are arranged in the casing 1, a wire outlet hole is opened on the top of the casing 1, and the braided wire formed by the braiding mechanism extends upward and passes through the wire outlet hole to be led out of the casing 1, and a guide component 3 and a winding mechanism 2 are installed outside the casing 1, wherein the guide component 3 is arranged near the wire outlet hole, and the winding mechanism 2 is arranged on one side of the bottom of the casing 1.

[0033] Specifically, the wires used for braiding extend to the braiding mechanism through the wire-releasing mechanism, and are twisted together to form a braided wire under the action of the braiding mechanism. The braided wire extends upward and is led out through the wire outlet hole, and extends to the winding mechanism 2 through the guide assembly 3, and finally winds up at the winding mechanism 2 to complete the winding. The above-mentioned wire-releasing mechanism and braiding mechanism both adopt the existing technology in the field, and will not be described in detail here.

[0034] Reference Figure 1 The guide assembly 3 includes a guide wheel 32 mounted on the top of the housing 1. The guide wheel 32 and the braided wire drawn out from the wire outlet are in the same vertical plane, and the outer circumference of the guide wheel 32 corresponds to the braided wire, so that the braided wire can bypass the outer circumference of the guide wheel 32 and extend to the winding mechanism 2. Preferably, an inwardly recessed annular groove is formed on the outer circumference of the guide wheel 32, and the braided wire bypassing the guide wheel 32 is accommodated in the annular groove, so that the position of the braided wire can be limited.

[0035] The winding mechanism 2 includes a driving assembly 21, a rotating seat 22 and a winding drum 23, wherein the driving assembly 21 is installed at the bottom of the housing 1, and its driving end is connected to the rotating seat 22, and the winding drum 23 is detachably installed on the rotating seat 22. When the driving assembly 21 is started, it can drive the rotating seat 22 to rotate toward the fixed position, thereby driving the winding drum 23 to rotate and winding the braided wire.

[0036] Furthermore, the driving assembly 21 includes a third driver 211 and a gear transmission group connected to the third driver 211. The third driver 211 drives one of the gears in the gear transmission group to rotate, which can drive another gear to rotate. The above-mentioned rotating seat 22 is connected to the gear, thereby driving the rotating seat 22 to rotate.

[0037] Reference Figure 2 The drive assembly 21 also includes a coupling 213 installed at the output end of the third driver 211, and a magnetic powder brake 214 connected to the coupling 213. When the third driver 211 drives the gear to rotate, the magnetic powder brake 214 passes current to control the gear speed, thereby controlling the rotation of the rotating seat 22 and the winding drum 23. It can be understood that since the distance of the braided wire from the braiding mechanism and the winding mechanism 2 is constant, and the speed at which the braided wire is supplied from the braiding mechanism to the winding mechanism 2 is constant, when the rotation speed of the winding drum 23 is controlled, the tension of the braided wire transmitted between the braiding mechanism and the winding mechanism 2 will change, thereby realizing the adjustment of the winding tension through the magnetic powder brake 214.

[0038] In coordination with it, the guide assembly 3 also includes a mounting base 31 fixed on the casing 1, and the above-mentioned guide wheel 32 is arranged on the mounting base 31, and a gravity sensor 33 is also installed on the mounting base 31. The guide wheel 32 and the gravity sensor 33 are arranged in coordination with each other. When the braided wire passes around the guide wheel 32 and extends toward the winding mechanism 2, the tension of the braided wire itself will exert a downward pressure on the guide wheel 32, and the downward pressure is detected by the gravity sensor 33, so that the tension of the braided wire can be recorded in real time. The staff adjusts the current supplied to the magnetic powder brake 214 according to the detected tension to ensure the stability of the tension of the braided wire during the winding process.

[0039] Furthermore, the rotating seat 22 includes a rotating shaft 221 and a limiting plate 1 222 and a limiting plate 223 sleeved on the rotating shaft 221. One end of the rotating shaft 221 is connected to the gear transmission group. The limiting plate 1 222 is fixedly connected to the rotating shaft 221. The limiting plate 223 is slidably connected to the rotating shaft 221. The winding drum 23 is arranged between the limiting plate 1 222 and the limiting plate 223. During the winding process, the limiting plate 1 222 and the limiting plate 223 can limit the axial displacement of the winding drum 23. After the winding is completed, the limiting plate 223 is removed from the rotating shaft 221, and the winding drum 23 can be removed and replaced. It can be understood that in order to enable the winding drum 23 to rotate with the rotating shaft 221, a key connection is adopted between the winding drum 23 and the rotating shaft 221. In addition, in order to improve the limiting effect of the limiting plate 1 222 and the limiting plate 223 on the winding drum 23, a clamping structure can be used between the limiting plate 223 and the rotating shaft 221 to ensure that the limiting plate 223 is not easily displaced when the winding drum 23 is in the process of winding; the clamping effect can be released when the winding drum 23 is replaced. The relevant technical solutions of the clamping structure adopt common knowledge and are not specifically limited here.

[0040] Reference Figure 3 , the housing 1 is also provided with a matching tension holding component 4 and a pressing component 5, both of which are arranged on the path of the braided wire extending from the guide component 3 to the winding mechanism 2, wherein the tension holding component 4 is relatively arranged on the side close to the guide component 3. When the winding drum 23 needs to be replaced, the pressing component 5 presses and fixes the end of the braided wire close to the winding mechanism 2, and the staff can remove the winding drum 23 by cutting the braided wire between the pressing component 5 and the winding mechanism 2. When replacing a new winding drum 23, the tension holding component 4 can apply pressure to the braided wire between the guide component 3 and the pressing component 5, so that when the braiding mechanism and the wire release mechanism operate normally, the generated braided wire continues to be supplied to the guide component 3, and at this time, the braided wire tension between the tension holding component 4 and the braiding mechanism becomes smaller, and the pressure applied to the braided wire by the tension holding component 4 can restore the tension of the braided wire, so that during the process of replacing the winding drum 23, the braiding mechanism operates normally and the braided wire maintains a certain tension.

[0041] Specifically, the clamping assembly 5 includes a second wire roller 51 fixed on the housing 1, and a clamping plate 52 arranged in cooperation with the second wire roller 51. One end of the clamping plate 52 is connected to a second driver 53, and the second driver 53 can drive the clamping plate 52 to rotate in a direction close to or away from the wire roller. When winding the wire normally, the braided wire passes between the clamping plate 52 and the second wire roller 51, and is not subject to external forces from the wire roller and the clamping plate 52; when the winding drum 23 is replaced, the clamping plate 52 approaches the second wire roller 51 and abuts against the surface of the second wire roller 51, and the braided wire passing between the two is then clamped between the second wire roller 51 and the clamping plate 52.

[0042] Furthermore, the pressing plate 52 is composed of a rotating part 521 and a pressing part 522, the rotating part 521 is a horizontally extending plate-like structure, the output end of the second driver 53 is connected to one end of the rotating part 521, and the pressing part 522 is integrally formed at the other end of the rotating part 521. The pressing part 522 is an arc-shaped structure adapted to the wire-passing roller 2 51, and when the pressing plate 52 abuts against the wire-passing roller 2 51, the pressing part 522 can fully contact the wire-passing roller 2 51, effectively improving the fixing effect of the braided wire.

[0043] The tension holding assembly 4 includes a wire roller 41 fixedly mounted on the housing 1, and the outer side of the wire roller 41 is rotatably connected to a winding wheel 42, and the winding wheel 42 can rotate in a vertical plane around the central axis of the wire roller 41, and the rotation plane of the winding wheel 42 coincides with the vertical plane where the guide wheel 32 is located. The tension holding assembly 4 also includes a first driver 43 that drives the winding wheel 42 to rotate. The braided wire drawn from the guide assembly 3 passes between the wire roller 41 and the winding wheel 42. When the winding wheel 42 rotates in a direction close to the braided wire, the winding wheel 42 can apply pressure to the braided wire, so that the braided wire moves with the winding wheel 42, thereby increasing the length of the braided wire between the guide assembly 3 and the tension holding assembly 4, so that the braided wire always maintains a certain tension when the braiding mechanism continues to work. It can be understood that the rotation speed and size of the winding wheel 42 need to be determined comprehensively based on the braiding speed of the braiding mechanism and the speed of disassembling and replacing the winding roller, and are not specifically limited here.

[0044] Reference Figure 3 and Figure 4A wire arrangement assembly 6 is also provided on the path where the braided wire extends from the guide assembly 3 to the winding mechanism 2. The wire arrangement assembly 6 is provided close to the winding mechanism 2 and is used to control the position of the braided wire on the winding drum 23 during the winding process so that the braided wire on the winding drum 23 is evenly distributed. Specifically, the wire arrangement assembly 6 includes an electric slide rail 61 installed on the housing 1, and a wire arrangement wheel 62 provided on the electric slide rail 61. The plane where the wire arrangement wheel 62 is located is parallel to the plane where the guide wheel 32 is located. The electric slide rail 61 extends along the axis of the winding drum 23. When the electric slide rail 61 is started, the wire arrangement wheel 62 can move back and forth left and right along the extension direction of the electric slide rail 61. It can be understood that the moving range of the wire arrangement wheel 62 should be at least equal to the length of the winding portion of the winding drum 23.

[0045] The implementation principle of the wire take-up device of a high-speed braiding machine in the embodiment of the present application is as follows: the braided wire is led upward in the housing 1, and is fixed on the winding drum 23 after passing through the guide component 3, the tension holding component 4, the clamping component 5 and the wire arrangement component 6 in sequence, and the winding drum 23 is driven to rotate by the driving component 21 to wind the braided wire on the winding drum 23. During the winding process, the gravity sensor 33 can detect the tension of the braided wire. When the tension changes, the staff adjusts the rotation speed of the winding drum 23 through the magnetic powder controller, thereby adjusting the tension of the braided wire.

[0046] When the braided wire wound on the winding drum 23 is about to be saturated, the second driver 53 drives the clamping plate 52 to rotate toward the wire roller 2 51 to clamp and fix the braided wire. Then the staff cuts the braided wire and removes the limiting plate 223 and the winding drum 23. During this process, the first driver 43 drives the winding wheel 42 to rotate. The winding wheel 42 applies pressure to the braided wire passing through it, so that the braided wire can maintain a certain tension when the braiding mechanism continues to work. After replacing the new winding drum 23, the limiting plate 223 is reinstalled, and the braided wire clamped and fixed on the clamping assembly 5 is pulled and fixed on the winding drum 23. The first driver 43 drives the winding wheel 42 to rotate in the opposite direction, and the driving assembly 21 drives the winding drum 23 to rotate again to wind the wire.

[0047] The above are all 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.
