Description

Technical Field

[0001] The utility model relates to the technical field of cable traction devices, in particular to a cable production extrusion traction device. Background Art

[0002] Cable production extrusion traction devices are essential equipment in the cable manufacturing process. They are primarily responsible for pulling and guiding the cable during the manufacturing process, ensuring it follows a predetermined path and speed, enabling a continuous and efficient production process. The social background and technological development of this device are closely tied to technological advancements and market demand in the wire and cable industry. With the increasing electrification of modern society, the demand for wire and cable continues to grow, particularly in power and communications infrastructure, as well as various consumer electronics. This demand for high-quality cable is driving technological innovation and functional enhancements in cable production equipment, including extrusion traction devices. Market demand for high-speed, efficient, and reliable cable production lines has led to continuous optimization of traction device design to accommodate varying production speeds and cable specifications. The development of cable production extrusion traction devices is closely tied to the high demands placed on wire and cable product quality and production efficiency in modern industrial society. Technological advancements and market demand are driving innovation in traction device technology, while environmental regulations and industry standards are also placing new demands on its design and operation.

[0003] Conventional cable extrusion and pulling devices are typically designed for cables of specific specifications. This means that for cables of varying diameters or types, the pulling device requires multiple rollers of varying specifications, increasing tool complexity and cost. This inability to adapt to varying cable specifications limits the flexibility of conventional pulling devices in practical applications. This reduces efficiency, particularly in applications requiring the handling of multiple cable specifications. When conventional cable extrusion and pulling devices encounter cables that do not meet their design specifications, additional installation steps are required, adding complexity and time to the process, impacting overall project progress and efficiency. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings of the prior art and to propose a cable production extrusion and pulling device.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical solutions: a cable production extrusion traction device, comprising a bottom plate, a traction box is fixed on the upper end surface of the bottom plate, a support frame is fixed on the upper end surface of the bottom plate, a cable drum is detachably connected to the inside of the support frame, a roller is rotatably connected to the inside of the traction box, a No. 1 gear is fixed to the surface of the roller, a rotating plate is rotatably connected to the back of the No. 1 gear, a No. 2 gear is rotatably connected to the surface of the rotating plate, a No. 3 gear is meshed with the surface of the No. 2 gear, the No. 3 gear is rotatably connected to the rotating plate, and a driving motor is provided on the back of the No. 3 gear. The rotating plate has a connecting plate rotatably connected to its surface. The bottom of the connecting plate is rotatably connected to a second gear. The connecting plate has an intermediate plate rotatably connected to its surface. The bottom of the intermediate plate is rotatably connected to a connecting plate. The bottom of the connecting plate is rotatably connected to a third gear. The bottom of the connecting plate is rotatably connected to a rotating plate. The surface of the rotating plate is rotatably connected to a piston air pump. The rotating plate is rotatably connected to the traction box. Conventional cable extrusion and traction devices are typically only suitable for cables of specific specifications. This means that for cables of different diameters or types, the traction device requires multiple rollers of different specifications, increasing the complexity and cost of the tool. This inability to accommodate different cable specifications limits the flexibility of conventional traction devices in practical applications. This reduces work efficiency, especially in applications where multiple cable specifications need to be processed. When conventional cable extrusion and traction devices encounter cables that do not meet their design specifications, additional installation steps are required, which undoubtedly increases the complexity and time consumption of the operation. This impacts the overall project progress and efficiency. To address this issue, the present invention utilizes a gear mechanism. When workers need to extrude and traction cables, the device uses a drive motor to rotate the first gear. Gear 1 meshes with gear 2, which in turn meshes with gear 3. This interlocking series of gears transmits the drive motor's power to the entire roller mechanism. Synchronously operating with the gear mechanism is a hydraulic air pump system, which propels the connecting plate, link plate, rotating plate, and intermediate plate. The coordinated movement of these plates ultimately adjusts the gap between the traction rollers. This allows the traction device to adjust the gap between the rollers to accommodate varying cable diameters. This adjustment ensures cable stability and adaptability during traction, preventing cable damage or poor traction performance due to improper clearances, thereby improving efficiency and quality.

[0006] Preferably, the support frame includes a fixed base fixed within it, a knob rotatably connected to the fixed base, a pressure plate slidably connected to the knob surface, a fixing pin fixed to the bottom of the knob, and a sliding groove formed on the fixed base surface. Conventional cable pulling devices typically utilize a threaded connection to mount the cable reel. While this installation method is simple, the threaded connection requires alignment of the threaded holes before tightening, a process that is often time-consuming and significantly reduces productivity, particularly when the cable reel is frequently replaced. Workers must carry additional tools, such as wrenches or screwdrivers, to manually tighten or loosen the holes, which not only complicates the work but can also lead to improper installation or over-tightening, compromising the stability of the device and the quality of the cable. Threaded connections require high hole precision; inaccurate alignment can cause the reel to be installed crookedly, thereby compromising the cable pulling efficiency and quality. Over time, the threads are susceptible to wear and damage, which compromises connection reliability and increases maintenance costs and time. Threaded connections can also gradually loosen under prolonged vibration and tension, and in extreme cases, can even cause the cable reel to fall off, resulting in safety hazards. Once the threaded connection is completed, to adjust the position of the cable reel or replace a reel of different specifications, it is usually necessary to completely disassemble it and re-thread it, which reduces the flexibility and adaptability of the device. In some compact traction devices, space is limited, and the operating space of the threaded connection is restricted, which brings additional difficulties to installation and maintenance. The threaded connection part is prone to accumulation of dirt and corrosion, and requires regular cleaning and maintenance, which increases maintenance costs. To address such problems, the utility model adopts a movable knob structure. When the staff installs and replaces the cable sleeve, by turning the movable knob, the fixing pin can be easily disengaged along the slide groove of the fixed base, thereby realizing rapid replacement of the cable reel and greatly improving work efficiency. The staff does not need to use additional tools, and can complete the operation by simply turning the knob, which reduces the complexity of the operation, alleviates labor intensity, and at the same time reduces surface bolt wear.

[0007] Preferably, a base is fixed at the bottom of the base plate, a pulley is rotatably connected to the surface of the base, a connecting spring is fixed inside the base, a shock-absorbing spring is fixed inside the base, and a hydraulic air pump is fixed inside the base. By adopting a shock-absorbing device, the vibration or impact energy is converted into the energy of the shock-absorbing spring and the connecting spring, and at the same time, a part of the energy is converted into the internal energy of the hydraulic air pump for consumption, thereby greatly improving the stability and reliability of the equipment in long-term operation.

[0008] Preferably, the surface of the knob is covered with a rubber sleeve. The soft texture of the rubber sleeve can improve the feel when pressing, provide a more comfortable and natural pressing experience, and further enhance the user's feel.

[0009] Preferably, a support spring is fixed inside the fixed base, so that after the fixing pin rotates to the fixed bottom, the support spring lifts the fixing pin and makes it close to the protrusion of the sliding groove, thereby making the knob fixation more stable.

[0010] Preferably, the shock-absorbing spring adopts a double-strand spring, which can more effectively absorb and reduce external impact force, which is particularly important during the operation of mechanical equipment and can significantly reduce the wear and failure rate of the equipment. Due to the double-strand structure, each spring shares part of the external force, thereby making the overall spring system more stable and extending the service life.

[0011] Beneficial effects

[0012] 1. Conventional cable extrusion and traction devices are typically designed for cables of specific specifications. This means that for cables of varying diameters or types, the traction device requires multiple rollers of varying specifications, increasing the complexity and cost of the tool. This inability to accommodate diverse cable specifications limits the flexibility of conventional traction devices in practical applications. This reduces efficiency, particularly in applications requiring the processing of multiple cable specifications. When conventional cable extrusion and traction devices encounter cables that do not meet their design specifications, they require additional installation steps, which undoubtedly increases operational complexity and time consumption. This impacts the overall project progress and efficiency. To address this issue, the present invention utilizes a gear mechanism. When extruding and traction cables, the device uses a drive motor to rotate gear number one. Gear number one meshes with gear number two, which in turn meshes with gear number three. This meshing series of gears transmits power from the drive motor to the entire roller mechanism. Synchronously operating with the gear mechanism is a hydraulic pump system that drives the connecting plate, connecting plate, rotating plate, and intermediate plate. The coordinated movement of these plates ultimately adjusts the gap between the traction rollers. This allows the traction device to adjust the gap between the rollers according to the diameter of cables of different specifications. This adjustment ensures the stability and adaptability of the cable during traction, avoids cable damage or poor traction results caused by improper gaps, and improves work efficiency and quality.

[0013] 2. Conventional cable pulling devices typically use a threaded connection to install the cable reel. While this installation method is simple, threaded connections require alignment of the threaded holes before tightening, a time-consuming process that significantly reduces productivity, especially when frequently replacing cable reels. Workers must carry additional tools, such as wrenches or screwdrivers, to manually tighten or loosen the reels. This not only complicates the work but can also lead to improper installation or over-tightening, compromising the stability of the device and the quality of the cable. Threaded connections require precise hole alignment. Improper alignment can cause the reel to be installed crookedly, compromising the cable pulling performance and quality. Over time, threads can easily wear or damage, compromising connection reliability and increasing maintenance costs and time. Threaded connections can gradually loosen under prolonged vibration and tension, and in extreme cases, can even cause the cable reel to fall off, resulting in safety hazards. Once the threaded connection is established, adjusting the position of the cable reel or replacing it with a reel of a different size typically requires complete disassembly and re-threading, reducing the device's flexibility and adaptability. In some compact traction devices, limited space and limited access to threaded connections create additional difficulties during installation and maintenance. Threaded connections are prone to accumulation of dirt and corrosion, requiring regular cleaning and maintenance, increasing maintenance costs. To address this issue, the present utility model utilizes a movable knob. When installing or replacing the cable reel, workers simply turn the knob to release the securing pin along a sliding groove in the fixed base, enabling quick replacement of the cable reel and significantly improving work efficiency. Workers can complete the operation with a simple turn of the knob, eliminating the need for additional tools. This reduces operational complexity and labor intensity, while also minimizing surface bolt wear. BRIEF DESCRIPTION OF THE DRAWINGS

In the prior art, traditional cable extrusion traction devices are generally only suitable for cables of specific specifications. This means that for cables of different diameters or types, the traction device needs to prepare multiple rollers 2 of different specifications, which increases the complexity and cost of the tool. Due to the inability to adapt to cables of different specifications, the flexibility of traditional traction devices in actual applications is limited. This leads to reduced work efficiency, especially in situations where multiple specifications of cables need to be processed. When traditional cable extrusion traction devices encounter cables that do not meet their design specifications, additional steps are required for installation, which undoubtedly increases the complexity and time consumption of the operation. This affects the overall project progress and efficiency. To address this issue, the present invention utilizes a gear mechanism. When workers need to extrude the traction cable, they use the device to drive motor 2041 to rotate gear 1 201. Gear 1 201 meshes with gear 2 203, which in turn meshes with gear 3 204. This interlocking series of gears transmits power from the drive motor 2041 to the entire roller 2 mechanism. Synchronously operating with the gear mechanism is a hydraulic air pump 403 system, which drives the connecting plate 207, connecting plate 205, rotating plate 202, and intermediate plate 206. The coordinated movement of these plates ultimately adjusts the gap between the traction rollers 2. This allows the traction device to adjust the gap between the rollers 2 to accommodate varying cable diameters. This adjustment ensures cable stability and adaptability during the traction process, preventing cable damage or poor traction performance due to improper gaps, thereby improving work efficiency and quality.

[0026] The working principle of this utility model is as follows: When a worker needs to extrude the traction cable, they use the device to drive the motor 2041 to rotate gear 1 201. Gear 1 201 meshes with gear 2 203, which in turn meshes with gear 3 204. This meshing of gears transmits the power of the drive motor 2041 to the entire roller 2 mechanism. Synchronously operating with the gear mechanism is a hydraulic air pump 403 system, which is responsible for driving the connecting plate 207, the connecting plate 205, the rotating plate 202, and the intermediate plate 206. The coordinated movement of these plates ultimately adjusts the gap between the traction rollers 2.
