[0001] The invention relates to the technical field of cable twisting equipment, and in particular to a twisted wire dragging bag mechanism. Background Art

[0002] Wire twisting machine is a kind of mechanical equipment that can be widely used in twisting various soft / hard conductor wires, so that multiple single conductors are twisted into one strand to meet the process requirements of wire materials. Wire twisting machines can generally be divided into single twisting machines, pair twisting machines, high-speed twisting machines, back-twisting machines, cage twisting machines, frame twisting machines, tubular twisting machines and disc twisting machines according to the twisting method. In the twisting process of the cable, due to improper control of the released strands and unstable supply, the stranded auxiliary wires wrapped around the cable will become loose, affecting the molding quality, transmission performance and service life of the cable.

[0003] In view of this, the present application proposes a stranded wire dragging bag mechanism that can flexibly control the tension of the released stranded wires when the cables are stranded. Summary of the invention

[0004] In order to overcome the above-mentioned disadvantages, the object of the present invention is to provide a twisted wire dragging bag mechanism.

[0005] In order to achieve the above objectives, the technical solution adopted by the present invention includes:

[0006] A material unloading rack, on which a material unloading tray is rotatably mounted, a tension control device is disposed at the bottom of the material unloading rack, and the material unloading tray is restricted by the tension control device so as not to exceed a rotation speed threshold;

[0007] A buffer mechanism is configured on the unloading rack, and the buffer mechanism can tension and buffer the stranded wires released from the unloading tray so that the stranded wires wound on the cable always maintain an adaptive pre-tightening force.

[0008] The present application realizes that the stranded wire is wound through a buffer mechanism and then wound on a rotating cable, and the stranded wire is wound through the rotating cable, so that the stranded wire pulls the discharge tray to rotate the stranded wire drum to discharge the material, and the buffer mechanism is used to smooth the jumping of the stranded wire, which can effectively ensure the stability of the rotation of the discharge tray, ensure the stability of the tension of the released stranded wire, and improve the stranding effect of the cable. In addition, the maximum pay-off speed of the stranded wire drum is limited by the tension control device to avoid the problem of the released stranded wire being too loose.

[0009] In the preferred technical solution of the above-mentioned stranded wire dragging bag mechanism, the buffer mechanism at least includes a support frame arranged on the unloading frame, a guide rod arranged on the support frame, and a buffer roller slidably arranged on the guide rod through an elastic member, wherein the buffer roller is pushed to a stationary position on the guide rod with the aid of the elastic force of the elastic member.

[0010] In the preferred technical solution of the above-mentioned stranded wire dragging bag mechanism, a limiting structure is also arranged on the unloading rack, and the limiting structure is used to limit the position of the stranded wire released from the unloading tray so that the stranded wire passes through the buffer roller and is placed on both sides of the buffer roller.

[0011] In the preferred technical solution of the above-mentioned stranded wire dragging bag mechanism, the limiting structure comprises at least a first limiting roller and a second limiting roller, and the first limiting roller and the second limiting roller are respectively located on both sides of the supporting frame and relatively far away from the buffer roller.

Under the action of the elastic member, the buffer roller always presses the stranded wire tightly to maintain the tension of the stranded wire, and at the same time limits the maximum unwinding speed of the stranded wire drum through the tension control device to avoid the problem of the paid-out stranded wire being too loose, thereby ensuring the precision of the stranded wire wound on the cable, and ensuring the molding quality, transmission performance and service life of the cable.

DETAILED DESCRIPTION

[0024] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the protection scope of the present invention.

In addition, the terms "first" and "second" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0026] In addition, it should be noted that in the description of the present invention, unless otherwise clearly specified and limited, the terms "disposed", "connected" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0027] Based on the background technology, improper control and unstable supply of the released stranded wires may cause the stranded wire auxiliary wires wound on the cable to become loose, affecting the molding quality, transmission performance and service life of the cable. The present invention provides a stranded wire dragging bag mechanism, which aims to provide a buffer roller 44 that can elastically slide through an elastic member 43 on a discharge rack 1, and the released stranded wire passes through the buffer roller 44. Under the action of the elastic member 43, the buffer roller 44 always presses the stranded wire tightly to maintain the tension of the stranded wire, so as to ensure the precision of the stranded wire wound on the cable, and to ensure the molding quality, transmission performance and service life of the cable.

[0028] like Figures 1 to 4 As shown, the stranded wire dragging bag mechanism of the present invention comprises: a material unloading rack 1, on which a material unloading tray 2 is rotatably mounted, a tension control device 3 is arranged at the bottom of the material unloading rack 1, and the material unloading tray 2 is limited by the tension control device 3 so as not to exceed a rotation speed threshold; a buffer mechanism 4, which is arranged on the material unloading rack 1, and can tension and buffer the stranded wire released from the material unloading tray 2, so that the stranded wire wound on the cable always maintains an adaptive pre-tightening force.

[0029] See also Figure 1 , Figure 2 The unloading rack 1 is provided with a tension control device 3 and a unloading tray 2. The unloading tray 2 has a rotating shaft, and the rotating shaft of the unloading tray 2 is limited by the tension control device 3, so that when the unloading tray 2 rotates, the rotation speed of the unloading tray 2 will not exceed the range limited by the tension control device 3, thereby ensuring the stability of the rotation of the unloading tray 2 and preventing the length of the stranded wire released by the unloading tray 2 from exceeding the length of the stranded wire wound on the cable after the rotation speed of the unloading tray 2 exceeds the threshold, causing the released stranded wire to be in a loose state as a whole, thereby causing the cable stranding failure or poor stranding effect; at the same time, the rotation speed of the unloading tray 2 is limited by the tension control device 3, so that the stranded wire released by the unloading tray 2 can always maintain a certain tension after passing through the buffer mechanism 4, so that the stranded wire can always be wrapped tightly around the cable, thereby improving the cable stranding effect and having practicality.

[0030] See also Figure 1 , Figure 2 The buffer mechanism 4 is arranged on the unloading rack 1 on one side of the unloading tray 2. After the unloading tray 2 is rotated to release the stranded wire, the stranded wire is wound around the buffer mechanism 4 and then wound around the rotating cable. As the cable is wound around the stranded wire, the cable will jump, so that the stranded wire wound around the cable will jump accordingly. At this time, since the stranded wire is wound around the buffer mechanism 4, under the action of the buffer mechanism 4, the problem of uneven wire release caused by the stranded wire jump on the unloading tray 2 can be reduced, thereby improving the use effect of the present application and the stability of the cable strands, and improving the quality of the cable strands.

[0031] See also Figures 1 to 4 When twisting the cable, first fix the stranding drum on the discharge tray 2 so that the stranding drum and the discharge tray 2 rotate synchronously, pay out the stranding drum, and wind the laid-out strands around the buffer mechanism 4 and then around the rotating cable. The strands are wound through the rotating cable, and the strands pull the discharge tray 2 to rotate the stranding drum to discharge the material. At the same time, the buffer mechanism 4 smoothes the vibration of the strands, which can effectively ensure the stability of the rotation of the discharge tray 2, ensure the stability of the tension of the released strands, and improve the stranding effect of the cable.

[0032] In one or more embodiments, the buffer mechanism 4 includes at least a support frame 41 configured on the unloading frame 1, a guide rod 42 configured on the support frame 41, and a buffer roller 44 slidably configured on the guide rod 42 through an elastic member 43, wherein the buffer roller 44 is pushed to a stationary position on the guide rod 42 with the aid of the elastic force of the elastic member 43.

[0033] See also Figure 1 , Figure 2 , Figure 4The support frame 41 has two, and two parallel guide rods 42 are arranged between the two support frames 41 in the vertical direction. The top and bottom ends of the buffer roller 44 are both provided with slides. The two ends of the buffer roller 44 are slidably installed on the guide rod 42 through the slides. The two ends of the buffer roller 44 are threadedly connected to the slides. Through this arrangement, the vertical position of the buffer roller 44 can be adjusted to improve the applicability of the buffer roller 44 to cables of different sizes. An elastic member 43 is installed on at least one guide rod 42, and the two ends of the elastic member 43 are respectively installed on the support frame 41 and the buffer roller 44. With the help of the elastic force of the elastic member 43, the buffer roller 44 is pushed to a stationary state on the guide rod 42.

[0034] See also Figures 1 to 4 When twisting the cable, firstly, the stranding drum fixed on the unwinding tray 2 is unwinded, and the unwinding stranded wire is connected to the cable after passing through the buffer roller 44. Thereafter, the cable is controlled to rotate so that the stranded wire is continuously wound around the cable. At this time, the stranding drum and the unwinding tray 2 are rotated by the tension of the unwinding stranded wire, so that the unwinding tray 2 and the stranding drum rotate synchronously to unwind the wire. When the cable is wound, the stranded wire jumps up and down. When the stranded wire jumps violently and the tension of the stranded wire increases, the stranded wire can drive the buffer roller 44 to compress the elastic member 43. When the stranded wire jumps gently, the tension is reduced. When the strands are pulled relatively slowly, the elastic member 43 can be used to hold the strands tightly against the wire, thereby ensuring that the strands are pulled by the wire to drive the strand drum and the discharge tray 2 to rotate stably, thereby ensuring the uniformity and stability of the strands wound on the cable. In addition, the present application limits the maximum rotation speed of the discharge tray 2 through the tension control device 3, thereby avoiding the problem that the discharge tray 2 over-rotates due to the violent vibration of the strands, causing the strand drum to release more strands of wire, thereby avoiding the problem that the loose strands cannot be tightly and stably wound on the cable, thereby ensuring the stranding effect of the present application on the cable.

[0035] In one or more embodiments, a limiting structure is also configured on the unloading rack 1, and the limiting structure is used to limit the position of the stranded wire released from the unloading tray 2, so that the stranded wire passes through the buffer roller 44 and is placed on both sides of the buffer roller 44.

[0036] See also Figure 2 The limiting structure can arrange the strands released from the strand drum on the discharge tray 2 on both sides of the buffer roller 44. The strands located on both sides of the buffer roller 44 are in a triangular relationship with the buffer roller 44. Through this configuration, the tension of the strands on both sides of the buffer roller 44 can be guaranteed. At the same time, the distance that the buffer roller 44 moves on the guide rod 42 can be increased, and the applicability of the buffer roller 44 to different degrees of strand jump can be improved, thereby improving the scope of application of the present application and having practicality.

[0037] In one or more embodiments, the limiting structure at least includes a first limiting roller 51 and a second limiting roller 52 . The first limiting roller 51 and the second limiting roller 52 are respectively located on two sides of the support frame 41 and relatively far away from the buffer roller 44 .

[0038] See also Figure 1 , Figure 2 The first limiting roller 51 and the second limiting roller 52 are respectively located on both sides of the same support frame 41 , and the first limiting roller 51 and the second limiting roller 52 are relatively far away from the position when the buffer roller 44 is pushed to the static position by the elastic member 43 .

[0039] Before twisting the cable, first unwind the stranded wire drum fixed on the unwinding tray 2, and the unwinded stranded wire first passes around the first limiting roller 51, and then passes around the buffer roller 44 by the first limiting roller 51 to reach the second limiting roller 52, and then the stranded wire is fixed on the cable, and the rotation of the cable is controlled so that the stranded wire is rolled and wound around the cable; the stranded wire wound around the first limiting roller 51, the buffer roller 44 and the second limiting roller 52 in sequence has a triangular structure, and through this arrangement, the moving distance of the buffer roller 44 on the guide rod 42 can be increased, ensuring that the buffer roller 44 can adapt to strands with different degrees of jitter, thereby increasing the scope of application of the present application, and at the same time, the stability of the buffer roller 44 in calming the jittering stranded wire can be further improved.

[0040] In other possible embodiments, the limiting structure also includes a third limiting roller 53 and a fourth limiting roller 54; wherein the third limiting roller 53 and the fourth limiting roller 54 are arranged in a straight line with the first limiting roller 51 and the second limiting roller 52. After the strand is wound around the second limiting roller 52, the strand is wound around the third limiting roller 53 and the fourth limiting roller 54 in turn to further reduce the change in the preload force of the strand. At the same time, by replacing the positions of the third limiting roller 53 and the fourth limiting roller 54, the position of the strand can be changed to meet the usage requirements in different environments.

[0041] In one or more embodiments, the material discharging tray 2 is provided with a stud 6, and a pressure plate 7 is threadedly connected to the stud 6. Figure 1 , Figure 3 , the stud 6 rotates synchronously with the discharge tray 2, the pressure plate 7 is in a circular ring shape, and the pressure plate 7 and the stud 6 have matching threads; when fixing the wire drum on the discharge tray 2, first remove the stud 6 from the pressure plate 7, and then put the limiting circular hole of the wire drum into the stud 6, and use the pressure plate 7 to screw and tighten the wire drum to achieve the installation of the wire drum; through this arrangement, the replacement efficiency of the wire drum can be improved, and the cable stranding efficiency can be improved.

[0042] In one or more embodiments, the outer wall of the pressure plate 7 is provided with a rotating handle 71. Figure 1By rotating the handle 71 to drive the pressure plate 7 to rotate, the convenience of installing the pressure plate 7 can be improved. In other possible embodiments, the rotating handle 71 is located at the end connected to the pressure plate 7 and tilted upward; through this arrangement, the winch drum can be prevented from being entangled on the rotating handle 71 when releasing the wire, thereby ensuring the stability of the winch drum in releasing the wire.

[0043] In one or more embodiments, the elastic member 43 is a spring or elastic steel.

[0044] In one or more embodiments, the material rack 1 is configured to be height-adjustable. Figure 3 The unloading rack 1 includes a unloading platform, a base and a lifting structure arranged therebetween. The height of the unloading rack 1 can be adjusted by controlling the operation of the lifting structure. The lifting structure can be a driving cylinder. Alternatively, the lifting structure can be a first screw installed at the bottom of the unloading platform, a second screw installed on the top surface of the base, and a sleeve threadedly sleeved on the first screw and the second screw. The height of the unloading rack 1 can be adjusted by rotating the sleeve. The structure is simple, the operation is convenient, and the structure is practical.

[0045] In one or more embodiments, a movable roller is configured at the bottom of the unloading rack 1. The movable roller is not shown in the drawings, but this configuration can make the unloading rack 1 of the present application movable, thereby improving the convenience of the application of the stranded wire dragging bag mechanism of the present application and increasing the scope of application of the present application.

[0046] In one or more embodiments, the tension control device 3 is a magnetic tensioner. Figure 3 The magnetic tensioner has a rotating shaft, and the rotating shaft of the magnetic tensioner rotates synchronously with the rotating shaft of the discharge tray 2. By limiting the rotation speed of the discharge tray 2 by the magnetic tensioner, it is possible to avoid the problem that the discharge tray 2 rotates too fast, causing the wire drum to release too much wire, making the released wire strands in a loose state.
