Description

Technical Field

[0001] The utility model belongs to the technical field of cable untwisting equipment, in particular to a spiral cable untwisting machine. Background Technique

[0002] In the production of wire and cable, when stranding, the single wire is wound around a cylinder with the base circle as the diameter in a spiral manner. The single wire will bend everywhere, and at the same time, the single wire will also generate torsional deformation around its own axis, causing internal stress in the stranded wire. To avoid affecting the quality of the stranded wire, a spiral cable untwisting device is usually used to solve this problem. In real life, after the spiral cable untwisting device untwists and pays off the cable, it will be wound by a winding mechanism. However, the uniformity of winding the cable by most winding mechanisms is relatively general, thus reducing the winding effect of the cable.

[0003] A Chinese patent document (publication number CN220351315U) discloses a untwisting and pay-off machine, which includes a pay-off table. There are two load-bearing plates at the bottom of the pay-off table, and the load-bearing plates are integrally formed with the pay-off table. At the center position of the upper end of the pay-off table, there are two center table plates, and both center table plates are integrally formed with the pay-off table; it further includes: a bearing frame plate, which is arranged at a position on one side of a center table plate.

[0004] It can be seen that the above-cited patent document also has the same problem. In its winding process, the weight of the winding roller gradually increases to drive the winding roller to descend, and then the cable is wound onto the winding roller. In this way, the winding roller cannot wind the cable evenly, and the uniformity of winding the cable is relatively general, thus reducing the winding effect of the winding roller on the cable. Content of the Utility Model

[0005] The purpose of the utility model is to provide a spiral cable untwisting machine to solve the problems put forward in the background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: a spiral cable untwisting machine, which includes an untwisting machine main box for untwisting spiral cables. A fixed seat is installed on one side of the pay-off end of the untwisting machine main box. A fixed frame is installed at the bottom of the fixed seat. A motor is installed on one side of the fixed frame. A rotating shaft is installed at the output end of the motor. An auxiliary winding component is arranged on one side of the outer wall of the rotating shaft, and a winding roller is installed on the other side of the outer wall of the rotating shaft;

[0007] The auxiliary winding component includes a first bevel gear. The tooth edge of the first bevel gear is meshed with a second bevel gear. A transmission shaft is installed inside the second bevel gear. A first connecting rod is installed at one end of the transmission shaft. A second connecting rod is assembled on one side of the first connecting rod. A connecting block is assembled on one side of the second connecting rod. A vertical rod is installed at the top of the connecting block, and a wire feeding seat is installed at the top of the vertical rod.

[0008] As a preferred embodiment, connecting plates are provided through both sides of the wire feeding base, springs are installed on the opposite sides of the two connecting plates, and a plurality of first rollers are assembled at the inner bottom ends of the two connecting plates.

[0009] As a preferred embodiment, one end of the rotating shaft is connected to the inner side wall of the fixing frame by a bearing.

[0010] As a preferred embodiment, a slider is installed on one side of the connecting block, and the outer wall of the slider is slidably connected to the back surface of the fixing frame.

[0011] As a preferred embodiment, there are two second rollers at the common bottom ends of both sides of the inner wall of the wire feeding base, and the top ends of the second rollers are higher than the height of the inner bottom end of the wire feeding base.

[0012] As a preferred embodiment, the opposite ends of the two springs are respectively fixedly connected to both sides of the wire feeding base.

[0013] Compared with the prior art, the technical effects and advantages of the present utility model are as follows:

[0014] For this spiral cable untwisting machine, thanks to the design of the auxiliary winding component, when the motor works and drives the winding roller to rotate and wind through the rotating shaft, it also drives the auxiliary winding component to move through the rotating shaft, causing the wire feeding base in the auxiliary winding component to move left and right reciprocally. In this way, the cable can be evenly wound on the winding roller, improving the winding effect of the winding roller;

[0015] By arranging the first rollers and springs in the wire feeding base, under the cooperation of the first rollers and the springs, the acting force between the cable during the winding process and the wire feeding base can be buffered and eliminated, avoiding damage to the cable.

[0027] This embodiment provides a Figures 1 to 4 helical cable untwisting machine as shown, including a main box 1 of the untwisting machine for helical cable untwisting. A fixing seat 2 is installed on one side of the wire releasing end of the main box 1 of the untwisting machine.

The top of the vertical rod 607 is installed with a wire feeding seat 608. During the process that the transmission shaft 603 rotates to drive the first connecting rod 604 to rotate by 180 degrees, the connecting block 606 is driven to move leftward through the second connecting rod 605. During the process that the transmission shaft 603 continues to rotate to drive the first connecting rod 604 to rotate by 360 degrees, the connecting block 606 is driven to move rightward through the second connecting rod 605. In this way, the cable can be evenly wound on the winding roller 7.

[0029] The motor 4 and the main box 1 of the torque releasing machine are conventional instruments, and their working principles, dimensions and models are irrelevant to the functions of this application, so no more description will be made. The control mode of the present utility model is controlled by a controller. The control circuit of the controller can be realized by simple programming of those skilled in the art. The provision of the power supply also belongs to the common knowledge in this field. And the present utility model is mainly used to protect mechanical devices, so the control mode and circuit connection of the present utility model will not be explained in detail.

[0030] In this embodiment, both sides of the wire feeding seat 608 are penetrated with connecting plates 8. The connecting plates 8 are L-shaped and are slidably connected to the wire feeding seat 608. Springs 9 are installed on the opposite sides of the two connecting plates 8. A plurality of first roller columns 10 are assembled at the inner bottom ends of the two connecting plates 8. The first roller columns 10 are connected to the connecting plates 8 by bearings. Under the cooperation of the first roller columns 10 and the springs 9, the acting force between the cable and the wire feeding seat 608 during the wire winding process can be buffered and eliminated, avoiding damage to the cable.

[0031] In this embodiment, one end of the rotating shaft 5 is connected to the inner side wall of the fixing frame 3 by bearings.

[0032] In this embodiment, a sliding block 609 is installed on one side of the connecting block 606. The sliding block 609 is T-shaped, and the outer wall of the sliding block 609 is slidably connected to the back surface of the fixing frame 3. A chute adapted to the sliding block 609 is opened on the back surface of the fixing frame 3.

[0033] In this embodiment, there are two second roller columns 11 at the common bottom ends of both sides of the inner wall of the wire feeding seat 608. The second roller columns 11 are connected to the wire feeding seat 608 by bearings. The top ends of the second roller columns 11 are higher than the height of the inner bottom end of the wire feeding seat 608, which is convenient for wire feeding of the cable.

[0034] In this embodiment, the opposite ends of two springs 9 are respectively fixedly connected to both sides of the wire output seat 608.

[0035] Working principle

[0036] The cable output from the wire releasing port of the main box 1 of the untwisting machine passes through the cable guiding frame and the wire output seat 608 in sequence and is fixed to the winding roller 7. Then, the motor switch is turned on, and the motor 4 works to drive the winding roller 7 to rotate through the rotating shaft 5, thereby winding the cable output from the wire releasing port of the main box 1 of the untwisting machine. Meanwhile, when the rotating shaft 5 rotates, it drives the second bevel gear 602 to rotate through the first bevel gear 601. When the second bevel gear 602 rotates, it drives the first connecting rod 604 to rotate through the transmission shaft 603. During the rotation of the first connecting rod 604, it drives the connecting block 605 to reciprocate left and right through the second connecting rod 605, thereby driving the wire output seat 608 to reciprocate left and right. In this way, the cable can be evenly wound on the winding roller 7, improving the winding effect of the winding roller 7.
