Abstract

The utility model relates to a heat dissipation stranding cage structure for a cabling machine. The heat dissipation stranding cage structure comprises a rack, a mounting ring and two supporting rings, the front and back surfaces of the wire winding drums are arranged in a staggered manner instead of being totally concentrated on the same side, so that the space structure of the stranding cage is greatly optimized, more wire coils can be mounted on the stranding cage under the condition of the same diameter, and the space utilization rate is remarkably improved. Due to the symmetrical and staggered layout, air circulation is facilitated during rotation, and an effective heat dissipation air channel is formed. Rotation can accelerate air to flow through gaps between the two sides of the stranding cage and the wire winding drum, so that heat generated by friction of the wire winding drum and a bearing is taken away in time, efficient natural air cooling heat dissipation is achieved, and temperature rise is effectively controlled.

Description

Technical Field

[0001] This utility model relates to the field of cable production technology, specifically to a heat dissipation winch structure for a cable-making machine. Background Technology

[0002] Cable forming machines are key equipment in the wire and cable manufacturing industry, used to strand multiple insulated wire cores or unit groups to form cable cores. During operation, the core component, the cable cage, involves multiple reels rotating synchronously to release the wire. Existing cable forming machine cages often employ a single-sided or densely packed reel holder structure, as seen in Chinese Invention Patent CN115295254B. However, existing cable forming machines and processing methods have significant drawbacks. The concentrated distribution of reel holders on one side results in low radial space utilization of the cable cage. To accommodate more reels, the cable cage diameter must be increased, leading to bulky equipment, increased rotational inertia, higher energy consumption, and difficulties in starting and stopping. Therefore, a new type of cable forming machine cage structure is urgently needed to achieve higher reel integration within a limited space. Utility Model Content

[0003] The main purpose of this utility model is to provide a heat dissipation auger structure for cable forming machines, so as to solve the problem that the existing cable forming machines and processing methods have obvious drawbacks, such as the spool seats being concentrated on one side, resulting in low radial space utilization of the auger.

[0004] To achieve the above objectives, this utility model provides a heat dissipation winch structure for a cable-making machine, including a frame, a mounting ring, and two support rings;

[0005] A horizontal shaft is mounted on the frame. The front end of the horizontal shaft is coaxially fixed with an annular plate, and the rear end is connected to a drive mechanism for rotating it. Multiple front holes are opened on the circumference of the annular plate.

[0006] The mounting ring is fixed in the middle of the horizontal shaft, and multiple sets of wire reel seats are circumferentially mounted on both the front and back sides.

[0007] Multiple wire-passing holes are opened around the circumference of the mounting ring, and multiple wire reel seats located on the front of the mounting ring are staggered with multiple wire reel seats located on the back of the mounting ring.

[0008] Two support rings are fixed on a horizontal shaft and located on both sides of the mounting ring. Each support ring is equipped with multiple guide wheels that rotate circumferentially.

[0009] A preferred embodiment is that the number of wire reel seats on the front side of the mounting ring is the same as the number of wire reel seats on the back side of the mounting ring.

[0010] A preferred embodiment is that the number of threading holes, multiple wire reel seats located on the back of the mounting ring, and guide wheels are the same, and the three correspond one-to-one.

[0011] A preferred embodiment is that the drive mechanism includes a driven sprocket and a motor;

[0012] The motor's base is fixedly connected to the frame, and the output shaft is fixedly fitted with a drive sprocket. The driven sprocket and the drive sprocket are fitted with a chain.

[0013] A preferred embodiment further includes a guide tube, which is fixedly connected to the frame via a bracket and located downstream of the annular plate, and is coaxially arranged with the horizontal axis.

[0014] A preferred embodiment is that the wire reel seat includes a flange, a shaft, and a limiting post for limiting the wire reel;

[0015] The flange is fixed on the front or back of the mounting ring. One end of the shaft is fixedly connected to the flange, and the other end is threaded with an external thread along the axial circumference of the horizontal shaft. One end of the limiting post is threaded with an internal thread hole on the same axis. The external thread is screwed into the internal thread hole. The wire reel is sleeved on the shaft.

[0016] A preferred embodiment is that the axis of the corresponding horizontal shaft, the axis of the threaded hole, and the axis of the shaft located on the back of the mounting ring are in the same plane.

[0017] A preferred solution is to coaxially mount a plastic tube in each threading hole.

[0018] The beneficial effects of the above scheme are:

[0019] Multiple wire reels are mounted on the wire reel seats on the front and back of the mounting ring. Because the wire reel seats on both sides are staggered, the wire reels on both sides are spatially offset, avoiding radial interference. The insulated wire cores on the back reels are sequentially passed through the corresponding through holes on the mounting ring, the corresponding front holes on the annular plate at the front of the horizontal shaft, and the corresponding front holes on the annular plate at the front of the horizontal shaft on the front reels, ultimately leading to the traction equipment at the front of the winch. The drive mechanism starts, causing the horizontal shaft and all its fixed components to rotate at high speed on the frame as a whole. All the wire reels mounted on both sides of the mounting ring rotate synchronously, passively releasing the wire. The multiple wire cores released from the reels continue to pass through the front holes on the annular plate at the front end. This structure further gathers and positions the wire cores, preparing for the next stranding step. As the wire bundle continues to move forward, it passes through guide wheels on two support rings. The function of these guide wheels is to constrain and guide the direction of the wire harness, ensuring it maintains a stable trajectory within the high-speed rotating auger. This prevents it from tangling or colliding with the inner wall of the equipment due to centrifugal force, thus smoothly conveying it to the stranding die. All wire cores are tightly stranded into cable cores at the stranding die. Throughout the process, the staggered layout of the wire drums, rather than all concentrated on one side, greatly optimizes the spatial structure of the auger, allowing more spools to be installed within the same diameter, significantly improving space utilization. This symmetrical and staggered layout facilitates airflow during rotation, forming an effective heat dissipation channel. The rotation itself accelerates the flow of air through the gaps between the sides of the auger and the wire drums, effectively carrying away the heat generated by drum friction and bearings, achieving efficient natural air cooling and effectively controlling temperature rise.

[0029] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Many specific details are set forth in the following description to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0030] Example:

[0031] like Figure 1 , Figure 2As shown, this embodiment provides a heat dissipation winch structure for a cable-making machine, including a frame 10, a mounting ring 20, and two support rings 40. A horizontal shaft 11 is horizontally mounted on the frame 10. The front end of the horizontal shaft 11 is coaxially fixedly fitted with an annular plate 12, and the rear end of the horizontal shaft 11 is connected to a drive mechanism 13 for rotating it. The drive mechanism 13 includes a driven sprocket 130 and a motor 131. The base of the motor 131 is fixedly connected to the frame 10, and the output shaft of the motor 131 is fixedly fitted with a drive sprocket 132. A chain 133 is fitted between the driven sprocket 130 and the drive sprocket 132. When the motor 131 starts, it drives the drive sprocket 132 to rotate. The drive sprocket 132 drives the driven sprocket 130 to rotate via the chain 133, and the driven sprocket 130 drives the horizontal shaft 11 to rotate. Multiple front holes 120 are formed around the circumference of the annular plate 12. The mounting ring 20 is fixedly sleeved in the middle of the horizontal shaft 11, and multiple sets of wire reel seats 30 are circumferentially mounted on both the front and back sides of the mounting ring 20. Each wire reel seat 30 includes a flange 31, a shaft 32, and a limiting post 33 for limiting the wire reel. The flange 31 is fixed to the front or back of the mounting ring 20. One end of the shaft 32 is fixedly connected to the flange 31, and the other end of the shaft 32 has an external thread (not shown) circumferentially along the horizontal shaft 11. One end of the limiting post 33 has a coaxial internal threaded hole (not shown), and the external thread is screwed into the internal threaded hole. The wire reel (not shown) is sleeved on the shaft 32. Multiple wire-passing holes 21 are circumferentially formed on the mounting ring 20. The multiple wire reel seats 30 on the front of the mounting ring 20 are staggered with the multiple wire reel seats 30 on the back of the mounting ring 20. The number of multiple wire reel seats 30 on the front of the mounting ring 20 is the same as the number of multiple wire reel seats 30 on the back of the mounting ring 20. The number of wire threading holes 21, multiple wire reel seats 30 on the back of the mounting ring 20, and guide wheels 41 are consistent and correspond one-to-one. By setting the number of wire reel seats 30 on both sides to be consistent and ensuring symmetrical distribution in structure, the center of mass of the winch can be strictly located on the axis of rotation when rotating at high speed. This greatly eliminates centrifugal force and vibration caused by uneven mass distribution. Constructing an independent and orderly wiring channel with the number of wire threading holes 21, wire reel seats 30 on the back, and guide wheels 41 being consistent and corresponding one-to-one, this design avoids multiple wire cores crossing, rubbing, and interfering with each other in a limited space, greatly reducing wear and scratches on the wire cores during the unwinding and twisting process. Two support rings 40 are fixed on the horizontal shaft 11 and located on both sides of the mounting ring 20, with multiple guide wheels 41 circumferentially mounted on each support ring 40.

[0032] Multiple wire reels are mounted on the wire reel seats 30 on the front and back of the mounting ring 20, respectively. Because the wire reel seats 30 on the front and back are staggered, the wire reels on both sides are spatially offset, avoiding radial interference. The insulated wire cores of each wire reel on the back side are sequentially passed through the corresponding wire-passing holes 21 on the mounting ring 20 and the corresponding front holes 120 on the annular plate 12 at the front end of the horizontal shaft 11, and the insulated wire cores of each wire reel on the front side are passed through the corresponding front holes 120 on the annular plate 12 at the front end of the horizontal shaft 11, ultimately leading to the traction equipment in front of the winch. The drive mechanism 13 is activated, causing the horizontal shaft 11 and all its fixed components to rotate at high speed on the frame 10 as a whole. All the wire reels mounted on both sides of the mounting ring 20 rotate synchronously, passively releasing the wire. Multiple wire cores released from the reel continue through the front holes 120 on the front annular plate 12. This structure further gathers and positions the wire cores, preparing them for the next stranding step. As the wire bundle continues forward, it passes guide wheels 41 on two support rings 40. These guide wheels 41 constrain and guide the direction of the wire bundle, ensuring it maintains a stable trajectory within the high-speed rotating auger, preventing it from tangling or colliding with the inner wall of the equipment due to centrifugal force, thus smoothly conveying it to the stranding die. All wire cores are tightly stranded into a cable core at the stranding die. Throughout the process, the staggered front and back layout of the reel, rather than all concentrated on one side, greatly optimizes the spatial structure of the auger, allowing more reels to be installed within the same diameter, significantly improving space utilization. This symmetrical and staggered layout also facilitates airflow during rotation, forming an effective heat dissipation channel. The rotation itself accelerates the flow of air through the gaps between the sides of the winding cage and the wire drum, thereby carrying away the heat generated by the friction of the wire drum and the bearings in a timely manner, achieving efficient natural air cooling and effectively controlling the temperature rise.

[0033] The guide tube 50 is fixedly connected to the frame 10 via a bracket 51 and is located downstream of the annular plate 12. The guide tube 50 is coaxially arranged with the horizontal shaft 11. Multiple wire cores emerging from the various front holes 120 of the rotating annular plate 12 have completed their initial convergence but still retain rotational inertia. These wire bundles are immediately guided into the guide tube 50. The axis of the corresponding horizontal shaft 11, the axis of the wire hole, and the axis of the shaft 32 located on the back of the mounting ring 20 are all in the same plane. The downstream guide wheel 41 is located directly behind its corresponding front hole 120. Each wire hole 21 is coaxially mounted with a plastic tube 14.

[0034] Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.
