Description

Technical Field

[0001] This utility model relates to the field of cable tube stranding technology, specifically a tube stranding machine for cable production. Background Technology

[0002] Wires and cables are wire products used to transmit electrical, magnetic, and information energy and to convert electromagnetic energy. Cables are usually made of several or several groups of conductors twisted together, resembling a rope. Each group of conductors is insulated from each other, and the entire cable is covered with a highly insulating outer layer. Cables have the characteristics of being internally energized and externally insulated.

[0003] Cable production and processing are inseparable from tube stranding machines. Tube stranding machines are a type of mechanical equipment that can be widely used to strand various soft and hard conductor wires, turning multiple single conductors into one strand to meet the process requirements of the wire. According to the stranding method, stranding machines can generally be divided into single stranding machines, pair stranding machines, high-speed stranding machines, untwisting machines, cage stranding machines, frame stranding machines, tube stranding machines, and disc stranding machines, etc.

[0004] In the practical application of traditional cable production tube stranding machines, the wire binding mechanism in the tube stranding machine is not adaptable enough and cannot be flexibly adjusted according to different cable thicknesses. It is very easy to have incomplete binding problems due to differences in cable specifications, which will lead to cable deviation and loosening during subsequent tube stranding, directly affecting the stranding quality. In addition, the uniformity of binding force is poor. Most wire binding components only apply binding force to the cable in a single direction or at a few points, which can easily cause excessive local stress on the cable, causing problems such as surface damage or internal structural deformation, significantly reducing the pass rate of cable products.

[0005] Therefore, we propose a cable stranding machine to solve the problems mentioned above. Utility Model Content

[0006] The purpose of this utility model is to provide a cable stranding machine to solve the problems mentioned in the background art, such as the insufficient adaptability of the wire bundling mechanism in traditional cable stranding machines, the inability to flexibly adjust according to different cable thicknesses, the easy occurrence of incomplete binding due to specification differences, which leads to cable deviation and loosening during subsequent stranding, affecting the stranding quality, and the poor uniformity of binding force, which easily causes excessive local stress on the cable, resulting in surface damage or internal structural deformation, and reducing the product qualification rate.

[0007] This utility model provides the following technical solution: a cable stranding machine, including a base, a stranding machine body mounted on the base, a stranding mechanism mounted on the stranding machine body, a cable body inserted through the stranding mechanism, a winding mechanism mounted on the stranding machine body, and a wire bundling assembly mounted on the stranding machine body. The wire bundling assembly includes a base frame fixedly connected to the base, a ring fixed on the base frame, a support plate fixed to the end of the ring, a telescopic rod fixed to the bottom surface of the support plate, and a clamping ring fixed to the end of the telescopic rod.

[0008] Preferably, the outer ring of the circular ring is rotatably fitted with a helical gear ring, and the support plate is rotatably connected with a helical gear, the helical gear meshing with the helical gear ring.

[0009] Preferably, the outer ring of the circular ring has a screw hole, the surface of the helical gear ring is fixed with a push rod, and the push rod is threaded with a screw.

[0010] Preferably, the screw holes are arranged in a circumferential array, and the screw is threaded into the screw holes.

[0011] Preferably, the helical gear, screw, and clamping ring are arranged in a circumferential array in multiples.

[0012] Preferably, the inner wall of the clamping ring is fitted to the outer wall of the cable body.

[0013] This utility model has the following beneficial effects: 1. This cable stranding machine, through the design of the cable bundling assembly, achieves precise fit between the clamping ring and the outer wall of cables of different thicknesses, solving the problem of incomplete binding caused by the fixed specifications of traditional cable bundling mechanisms. It achieves a stable binding effect for cables of multiple specifications. At the same time, by using multiple sets of components to apply balanced binding force to the cable from multiple directions, it effectively avoids surface damage or structural deformation caused by excessive local stress, and improves the appearance quality and structural integrity of the cable products.

[0014] 2. In terms of adjustment, the operator only needs to rotate the screw and push the push rod to quickly adjust the binding state without disassembling the parts, which shortens the switching time to adapt to different specifications of cables. This design reduces the difficulty of operation, improves production efficiency, and enhances the equipment's real-time response capability to dynamic production needs.

[0015] 3. The cable stranding machine effectively prevents the cable strand structure from shifting due to vibration and tension changes during operation by limiting the helical tooth ring, ensuring that the clamping state of the clamping ring remains stable over a long period of time. This feature reduces the occurrence rate of production failures and scrap rates, providing a solid guarantee for the continuous and efficient operation of cable production.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0022] This embodiment aims to address the problems of traditional cable conduit stranding machines being unable to adapt to cables of different thicknesses and lacking sufficient binding stability during the cable bundling process. Please refer to [link to relevant documentation]. Figure 1 - Figure 4 A cable stranding machine includes a base 1, on which a stranding machine body 2 is mounted. The stranding machine body 2 mainly consists of a welded steel frame, a drive system, and a control system. The drive system includes a main motor, a gearbox, and a transmission gear set, providing power output to the stranding mechanism 3 and the winding mechanism 6, and achieving precise control of the operating speed through frequency conversion speed regulation technology. The control system integrates a PLC control cabinet, an operation panel, and sensor components, which can preset stranding parameters and monitor the equipment operating status in real time. When an abnormality occurs, it automatically alarms and shuts down for protection.

[0023] This part of the structure is a standard configuration for cable stranding equipment in the cable production field. Its overall architecture, power transmission method and control logic are all existing technologies in this field and are not the core innovation of this solution, so they are not described in detail in the solution.

[0024] The main body 2 of the tube stranding machine is equipped with a stranding mechanism 3, which is the core working unit for stranding multiple conductors. It mainly consists of a auger, a wire distributor, guide wheels, and a twisting assembly. The auger is a hollow tubular structure with multiple conductor channels evenly distributed along the circumference inside to guide multiple conductors to be transported along a preset trajectory. The wire distributor is installed at the input end of the auger and performs preliminary sorting of the conductors through the wire distributor holes in a ring array to ensure that the entry position of each conductor is accurate. The guide wheel group is arranged at intervals along the axial direction of the auger to maintain the tension stability of the conductors during the transport process. The twisting assembly consists of a rotary bearing and a transmission gear. Driven by the drive system, the auger rotates around the axis, and the rotational motion twists multiple parallel conductors into a cable.

[0025] The structural design and working principle of this type of stranding mechanism 3 are widely used in existing cable stranding equipment. Its core functions and implementation methods are well-known technologies in this field and are not the direction of innovation and improvement of this solution, so they are not described in detail.

[0026] A cable body 4 is threaded through a stranding mechanism 3. A winding mechanism 6 is installed on a tube stranding machine body 2. A wire bundling assembly 5 is installed on the tube stranding machine body 2. The wire bundling assembly 5 includes a base frame 51 fixedly connected to a base 1. A ring 52 is fixed on the base frame 51. A support plate 55 is fixed to the end of the ring 52. A telescopic rod 56 is fixed to the bottom surface of the support plate 55. A clamping ring 57 is fixed to the end of the telescopic rod 56. The inner wall of the clamping ring 57 fits against the outer wall of the cable body 4. The design of the clamping ring 57 needs to take into account the protection of the cable and avoid damage to the cable sheath during the binding process. Therefore, the inner wall of the clamping ring 57 is usually made of a flexible material, such as rubber. The shape of the clamping ring 57 is adapted to the cross-sectional shape of the cable, and is usually circular to ensure that the binding force can be applied to the cable evenly.

[0027] The winding mechanism 6 is used to orderly wind up the stranded cable body 4. It mainly consists of a winding roller, a tension adjustment device, a cable guide, and a braking assembly. The winding roller is a cylindrical body that is mounted on the frame through a bearing seat and is driven to rotate by a drive motor via a chain drive. The tension adjustment device consists of a floating roller and a pressure sensor, which can detect the tension value of the cable during winding in real time and feed it back to the control system for dynamic adjustment. The cable guide adopts a screw and nut structure and is driven by a servo motor to reciprocate along the axial direction of the winding roller, so that the cable is evenly wound on the surface of the roller. The braking assembly is activated when the equipment stops and applies braking force to the winding roller through an electromagnetic brake to prevent the cable from loosening due to inertia.

[0028] The overall structure and control logic of the winding mechanism 6 are standard configurations for cable production equipment. Its technical solution has been used in the industry for a long time and is mature and stable. It is not the main innovation of this solution, so it is not described in detail in this solution.

[0029] A helical gear ring 54 is rotatably fitted onto the outer ring of a circular ring 52. A helical gear 58 is rotatably connected to the support plate 55. The helical gear 58 meshes with the helical gear ring 54. The tooth profile of the helical gear ring 54 and the helical gear 58 is designed as helical teeth. Compared with straight teeth, helical teeth are smoother during transmission, produce less noise, and can withstand greater loads. A screw hole 53 is provided on the outer ring of the circular ring 52. A push rod 510 is fixed to the surface of the helical gear ring 54. A screw 511 is installed on the internal thread of the push rod 510. The screw holes 53 are arranged in a circumferential array. 1. A screw 511 is threaded into screw hole 53. Multiple helical gears 58, screws 59, and clamping rings 57 are arranged in a circumferential array. Due to the threaded engagement of screw 511 with screw hole 53 and the fixed connection between push rod 510 and helical gear ring 54, when screw 511 moves in screw hole 53, it pushes push rod 510 to rotate helical gear ring 54. This, in turn, through the transmission between helical gear 58 and helical gear ring 54, allows for circumferential adjustment of clamping ring 57, better adapting to the binding requirements of cables of different thicknesses. Multiple helical gears 58, screws 59, and clamping rings 57 arranged in a circumferential array, working together, can uniformly bind the cable from multiple directions, ensuring the stability of the cable during the stranding process.

[0030] In this embodiment: In the cable production process, the multi-strand conductors are first precisely fed to the stranding mechanism 3 of the stranding machine body 2. The stranding mechanism 3 performs stranding operations on the multi-strand conductors inserted therein according to the preset rotation trajectory and twisting parameters. As the stranding mechanism 3 continues to operate, the multi-strand conductors are tightly twisted according to the set twisting pitch and direction, gradually forming the preliminary cable body 4. During this process, the conductors must always maintain stable tension and position to lay a solid foundation for the subsequent binding, fixing and winding processes.

[0031] Once the initially formed cable body 4 is output from the stranding mechanism 3, it immediately enters the binding range of the cable bundle assembly 5. The inner wall of the clamping ring 57 in the cable bundle assembly 5 is tightly fitted with the outer wall of the cable body 4, forming a stable binding on the cable from multiple directions, ensuring that it always maintains the correct alignment with the cable, thereby ensuring the effectiveness of the binding effect.

[0032] During the binding process, if cables of different thicknesses are encountered or the cable thickness changes, the clamping state of the clamping ring 57 can be precisely adjusted by rotating the helical tooth ring 54. In specific operation, the operator first rotates the screw 511 inside the push rod 510, so that the screw 511 rotates outward and exits the screw hole 53. At this time, the screw 511 is completely separated from the ring 52, and the helical tooth ring 54 obtains space to rotate freely around the outer ring 52. Subsequently, push rod 510 is pushed according to actual needs, causing helical gear ring 54 to rotate circumferentially along ring 52. During the rotation, helical gear ring 54 and helical gear 58 on support plate 55 form a meshing transmission, transmitting rotational motion to helical gear 58, causing it to rotate at a corresponding angle. Since helical gear 58 and screw 59 are threadedly connected, and screw 59 and clamping ring 57 are rotated, when helical gear 58 rotates, the screw 59 that is matched with it will rotate synchronously in support plate 55. The rotational motion of screw 59 drives the bottom clamping ring 57 to achieve telescopic adjustment. At the same time, telescopic rod 56 is stretched or contracted synchronously. With the lifting and lowering movement of screw 59, clamping ring 57 will accurately approach or move away from cable body 4, ultimately achieving tight clamping of cables of different thicknesses.

[0033] After adjustment, the operator needs to rotate screw 511 in the opposite direction to precisely embed it into the corresponding groove on the ring 52. The tight engagement between screw 511 and the groove reliably limits the position of the helical gear ring 54. This operation effectively locks the position of the helical gear ring 54, preventing it from rotating unexpectedly due to vibration, cable tension changes, or other factors during subsequent equipment operation. This ensures the stability of the clamping state of the clamping ring 57 and provides a solid guarantee for the continuous stability of the cable processing process. In addition, multiple helical gears 58, screws 59, and clamping rings 57 arranged in a circumferential array work together to apply uniform binding force to the cable from all directions, further improving the binding stability.

[0034] Through the above design, it can not only flexibly adapt to cables of different thicknesses, but also, through the combination of coarse adjustment of the telescopic rod 56 and adjustment of the helical gear ring 54 and helical gear 58, make the clamping ring 57 precisely fit the outer wall of various specifications of cables, completely avoiding the problem of incomplete binding caused by thickness differences; it can also ensure the uniformity of binding, with multiple sets of clamping rings 57 applying force from multiple directions to ensure that the cable is subjected to balanced force during the tube stranding and winding process, effectively preventing surface damage or deformation caused by excessive local force; and it can improve production stability, as a stable binding state can reduce problems such as cable deviation and loosening during processing, reduce the occurrence rate of production failures and scrap rates, and thus improve production efficiency and product quality. The cable body 4, which is stably bound by the cable bundle assembly 5, is continuously fed to the winding mechanism 6 of the tube stranding machine body 2. The winding mechanism 6 rotates smoothly under the drive of the motor, neatly and orderly winding the cable body 4 onto the winding roller. During the winding process, the operating speed of the winding mechanism 6 is always precisely matched with the cable conveying speed to ensure that the cable is wound with appropriate tension, and ultimately ensure that the winding quality meets the production standards.
