Description

Technical Field

[0001] This utility model relates to the field of stranding machines, and in particular to a stranding structure for stranding machines. Background Technology

[0002] A stranding machine is a device that twists multiple thin cables together to form a thick cable, commonly used in cable manufacturing. Existing cable stranding machines typically consist of two structures: the stranding machine body and the cable frame. The stranded cable is pulled outwards by a moving slide and rotated under tension to form the cable.

[0003] The prior art (announcement number: CN 220020733 U) discloses a conductor stranding structure for preparing cables, including: a workbench, a power unit, a feeding device, a stranding device, a wire bundling device, and a wire gathering device. The power unit, feeding device, stranding device, wire bundling device, and wire gathering device are arranged sequentially on the workbench. The power unit is coaxially connected to the feeding device and is coaxially connected to the stranding device through the feeding device. The stranding device includes: a disc fixing seat, a disc assembly block, a disc outer ring, a wire through hole, and a groove.

[0004] While the aforementioned patent enables the replacement of a single worn component without cutting the wire core, reducing maintenance time, it has the following drawbacks: when using a cable bundling device to guide the cable onto the cable gathering device for winding, the thickness of the cable on the gathering device gradually increases, causing the cable's position inside the cable bundling device to change. This increases the pressure of the cable contacting the inner wall of the cable bundling device, which may cause indentations or scratches on the cable surface, thereby damaging the cable's insulation layer and conductivity, affecting the overall quality and service life of the cable. Further improvements are needed. Therefore, a stranding structure for a stranding machine is proposed. Utility Model Content

[0005] The main purpose of this utility model is to provide a stranding structure for a stranding machine, which can effectively solve the problems in the background art.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A stranding structure for a stranding machine includes a base plate. From left to right, the upper end of the base plate is provided with a wire feed roller fixing frame, a support frame, a vertical plate, a reciprocating guide wire frame, and a U-shaped plate. A first motor is installed at the left end of the wire feed roller fixing frame. A stranding disc and a guide wire ring are respectively installed on the upper left and upper right parts of the support frame. Two tensioning wheels that can move up and down are provided at the front end of the vertical plate. A guide wire rod is installed on the front right part of the vertical plate. A take-up component is provided on the upper side of the U-shaped plate. The take-up component moves up or down to adjust the position of the cable within the reciprocating guide wire frame.

[0008] Preferably, the front inner wall and the rear inner wall of the U-shaped plate are jointly provided with a lifting component. The lifting component includes a positive and negative threaded rod, which is movably connected between the front inner wall and the rear inner wall of the U-shaped plate. The outer surface of the positive and negative threaded rod is threaded with two symmetrically distributed moving blocks. The lower walls of the two moving blocks are slidably connected to the lower wall of the U-shaped plate. The left and right ends of the two moving blocks are movably connected to a rotating plate through a rotating shaft. The four rotating plates are movably connected to a support plate through a rotating shaft.

[0009] Preferably, the positive and negative threaded rods are connected to the motor drive installed at the front end of the U-shaped plate.

[0010] Preferably, the take-up component is mounted on the upper end of the support plate.

[0011] Preferably, an L-shaped frame is installed at the upper end of the take-up component, and an infrared distance sensor is fixedly fitted inside the L-shaped frame.

[0012] Preferably, a linear displacement sensor is installed on the lower inner right side of the U-shaped plate, and the measuring end of the linear displacement sensor is fixedly connected to the lower end of the support plate.

[0013] Preferably, there are gaps between the front and rear ends of the support plate and the front and rear inner walls of the U-shaped plate.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. The height of the take-up device can be adjusted by setting up a lifting component. When the thickness of the cable wound by the take-up component increases, the control motor drives the positive and negative threaded rods to rotate. The positive and negative threaded rods drive the two moving blocks to move closer to each other. The two moving blocks drive the support plate to move upward through the rotating plate. The support plate drives the take-up component to move upward, thereby adjusting the position of the cable in the reciprocating conductor frame. This avoids excessive contact between the cable and the inner wall of the reciprocating conductor frame, reduces the pressure of contact with the inner wall of the reciprocating conductor frame, and avoids indentations or scratches on the cable surface that may affect the insulation layer and conductivity, thus ensuring the overall quality and service life of the cable.

[0016] 2. By setting a measuring component, the thickness of the cable on the surface of the take-up component can be measured. During use, the infrared light emitted by the infrared distance sensor can measure the increased thickness of the cable, and then transmit the data to the controller, so that the controller can automatically adjust the lifting component without the need for manual adjustment by the operator, thus improving the degree of automation.

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0024] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," and "connected," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0025] like Figures 1-4As shown, a stranding structure for a stranding machine includes a base plate 1. From left to right, the upper end of the base plate 1 is provided with a wire feed roller fixing frame 4, a support frame 2, a vertical plate 5, a reciprocating wire guide frame 8, and a U-shaped plate 9. The reciprocating wire guide frame 8 is composed of a bracket, a reciprocating lead screw, a motor bearing seat, and a wire drum, etc. The reciprocating wire guide frame 8 is used to drive the cable to move back and forth, so that the cable is evenly wound on the take-up component 10. A first motor 3 is installed at the left end of the wire feed roller fixing frame 4. The first motor 3, the wire feed roller fixing frame 4, and the stranding disc 12 are connected together. The transmission connection includes a winch 12 and a wire ring 13 installed on the upper left and upper right sides of the support frame 2, respectively. Two vertically movable tensioning wheels 6 are provided at the front end of the vertical plate 5. A wire rod 7 is installed on the right front side of the vertical plate 5. A take-up component 10 is provided on the upper side of the U-shaped plate 9. The take-up component 10 includes an L-shaped plate 105. A second motor 104 is installed at the rear end of the L-shaped plate 105. The output end of the second motor 104 movably passes through the front end of the L-shaped plate 105 and is fixedly connected to a connecting shaft 102. A baffle 103 is fixedly sleeved on the rear of the outer surface of the connecting shaft 102. The front of the outer surface of the connecting shaft 102 is threaded. The take-up roller 101 is fixedly sleeved on the outer surface of the connecting shaft 102 by a nut and thread. In use, the pay-off roller is fixed on the pay-off roller fixing frame 4 for fixed pay-off. The cable on the pay-off roller passes through the twisting disc 12 and the conductor ring 13 in sequence. The tension of the cable is then adjusted by two tensioning wheels 6. Finally, the cable is wound onto the take-up roller 101 through the conductor rod 7 and the reciprocating conductor frame 8. The first motor 3 is controlled to drive the pay-off roller fixing frame 4 and the inner ring of the twisting disc 12 to rotate, twisting multiple cables together. The second motor 104 is controlled to drive the take-up roller 101 to rotate, winding the twisted cable around its surface. The thickness of the cable on the take-up roller 101 will gradually increase, causing the position of the cable inside the conductor drum to change, causing the cable to move up or down. This results in increased pressure between the cable and the inner wall of the conductor drum, which may cause indentations or scratches on the cable surface, thereby damaging the cable's insulation layer and conductivity.

[0026] To address the aforementioned issues, a lifting component 17 is provided on both the front and rear inner walls of the U-shaped plate 9. This lifting component 17 allows for adjustment of the height of the take-up device. Specifically, the lifting component 17 includes a threaded rod 171, which is movably connected between the front and rear inner walls of the U-shaped plate 9. Two symmetrically distributed movable blocks 172 are threaded onto the outer surface of the threaded rod 171. The lower walls of both movable blocks 172 are slidably connected to the lower wall of the U-shaped plate 9. Rotating plates 173 are movably connected to the left and right ends of both movable blocks 172 via pivots. A support plate 174 is movably connected to all four rotating plates 173 via pivots. The threaded rod 171 is connected to a motor installed at the front end of the U-shaped plate 9. The take-up device 10 is mounted on the support plate 174. At the upper end, the L-shaped plate 105 is mounted on the support plate 174. The take-up roller 101 rotates counterclockwise. As the thickness of the cable wound on the take-up roller 101 increases, the control motor drives the positive and negative threaded rods 171 to rotate. The positive and negative threaded rods 171 drive the two moving blocks 172 to move closer to each other. The two moving blocks 172 drive the support plate 174 to move upward through the rotating plate 173. The support plate 174 drives the take-up component 10 to move upward, thereby adjusting the position of the cable in the reciprocating conductor frame 8. This avoids excessive contact between the cable and the inner wall of the reciprocating conductor frame 8, reduces the pressure of contact with the inner wall of the reciprocating conductor frame 8, and avoids indentations or scratches on the cable surface that affect the insulation layer and conductivity. This ensures the overall quality and service life of the cable. There are gaps between the front and rear ends of the support plate 174 and the front and rear inner walls of the U-shaped plate 9.

[0027] Furthermore, workers may find it inconvenient to know the thickness of the cable on the take-up roller 101, and the need to manually control the movement of the lifting component 17 increases their workload. To address these issues, an L-shaped frame 111 is installed at the upper end of the take-up component 10. An infrared distance sensor 112 is fixedly installed inside the L-shaped frame 111. The infrared distance sensor 112 is existing technology. It is electrically connected to the controller, which is electrically connected to the motor on the U-shaped plate 9. In use, the infrared light emitted by the infrared distance sensor 112 is reflected to measure the increased thickness of the cable. The data is then transmitted to the controller, enabling the controller to automatically adjust the lifting component 17 without requiring manual adjustment by workers, thus improving the level of automation.

[0028] In order to measure the distance the support plate 174 moves, a linear displacement sensor 18 is installed on the lower inner right side of the U-shaped plate 9. The measuring end of the linear displacement sensor 18 is fixedly connected to the lower end of the support plate 174. The height of the support plate 174 can be known through the linear displacement sensor 18, which facilitates precise control of the distance of the support plate 174.
