Description

Technical Field

[0001] This invention belongs to the technical field of power cable production equipment, specifically relating to a power cable stranding processing device with a damage prevention tension adjustment mechanism. Background Technology

[0002] A power cable stranding machine is a crucial piece of equipment used to strand multiple single-strand conductors into a single cable. The stranding quality directly affects the cable's conductivity, mechanical strength, and service life. However, existing stranding devices still have several shortcomings during operation: First, poor tension control. Most existing equipment uses passive friction or counterweights to adjust the tension, resulting in slow response and low control accuracy. Excessive tension can lead to overstretching or even breakage of the single filaments; insufficient tension will cause the wires to slack and the stranding to be loose, affecting product quality. Second, dust accumulation is a significant issue. Metal shavings, dust, and other contaminants in the stranding environment easily adhere to the surface of the single filaments. If not cleaned in time, they can be drawn into the stranded core, affecting the tightness of the strand and insulation performance. Therefore, there is an urgent need for a power cable stranding processing device that integrates precise tension control and effective dust prevention.

[0003] Publication number CN120280233B discloses a power cable stranding processing device with a loss-prevention tension adjustment mechanism, relating to the field of cable stranding technology. It improves the sub-wire conduction process during power cable stranding by specifically addressing the subsequent changing of the sub-wire and the preceding clamping process. The subsequent changing of the sub-wire essentially alters the bending degree of the sub-wire without interfering with its normal conduction, using multiple sets of guide rollers to coordinate with the number of sub-wires. The movement of the guide rollers is altered by the tension changes during sub-wire conduction, thus distributing any potential tension fluctuations evenly across all sub-wires, preventing large tension fluctuations in a single sub-wire from affecting the overall stranding process. The preceding clamping process does not interfere with the winding process of the sub-wire; it utilizes changes in magnetic force to create a clamping force on the sub-wire using permanent magnet beads, maintaining the stranding quality. The stranding is completed through the coordinated operation of these two processes.

[0004] No technical solution of the present invention was found after a search. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a power cable stranding processing device with a damage prevention tension adjustment mechanism, thereby solving the technical problems mentioned above in the background art.

[0006] The objective of this invention is achieved as follows: A power cable stranding processing device with a damage-prevention tension adjustment mechanism includes a frame, and a pay-off mechanism, a stranding mechanism, and a winding mechanism disposed on the frame. The frame also includes a tension adjustment mechanism positioned between the pay-off mechanism and the stranding mechanism, comprising a tension detection component and an active adjustment component. The tension detection component includes a detection wheel for guiding the monofilament, with a pressure sensor externally connected to the detection wheel. The active adjustment component includes a swing arm and a stepper motor for driving the swing arm, with a guide wheel connected to the swing arm for guiding the monofilament. The pressure sensor detects the tension of the monofilament and transmits a signal to the stepper motor, which drives the swing arm to swing and adjust the tension of the monofilament via the guide wheel. In use, the monofilament passes over the detection wheel and the guide wheel. Tension changes act on the detection wheel, are sensed by the pressure sensor, and converted into an electrical signal. The controller processes the signal and sends a command to the stepper motor. The stepper motor rotates precisely, causing the swing arm and guide wheel to swing, tightening or loosening the wire path to achieve tension stability. By integrating tension detection and active motor drive adjustment into one mechanism, a fundamental transformation has been achieved from passive buffering and mechanical adjustment to active, precise, and closed-loop control. This fundamentally solves the technical problems of inaccurate tension control and slow response in traditional devices, ensuring constant tension during stranding and significantly improving the uniformity and tightness of the strands.

[0007] Furthermore, the stranding mechanism includes a stranding base with multiple stranding channels. Several anti-wear components are arranged around the outer periphery of each stranding channel, connected to the stranding base. Each anti-wear component includes an auxiliary wheel to reduce wear on the monofilament during stranding. The auxiliary wheel has a concave arc surface on its circumference. A protective cavity and a cleaning component along the monofilament's travel path are arranged around the stranding mechanism. The cleaning component includes a cleaning cylinder and an air-collecting chamber communicating with the cleaning cylinder. The air-collecting chamber has an exhaust port facing the monofilament. The cleaning cylinder removes dust from the surface of the monofilament, which is then discharged through the exhaust port. In use, after passing through the cleaning component, surface dust is cleaned and blown off by the airflow. During stranding, the monofilament rolls into contact with the rotating auxiliary wheel, smoothly guiding it to the stranding point, reducing surface wear and insulation damage during stranding, and effectively preventing dust from being drawn into the stranded core, thus improving the product's electrical performance and quality.

[0008] Furthermore, a drive motor is connected to the stranding base, and the drive motor is connected to a main gear. The main gear meshes with a first gear ring, which drives several of the wear-resistant components. The main gear is connected to a transmission gear system, which drives the auxiliary wheel to rotate. In use, the drive motor starts, driving the main gear to rotate. The main gear drives the first gear ring to rotate, thereby causing all the wear-resistant components to revolve around the center of the stranding channel. Simultaneously, the main gear transmits power to the auxiliary wheel through the transmission gear system, causing it to rotate. This simple mechanical structure achieves the complex compound motion of the auxiliary wheel, ensuring continuous changes in the contact points of the monofilament wire, achieving uniform wear and effective heat dissipation, and improving the reliability of the equipment.

[0009] Furthermore, the twisting seat includes an outer ring seat, a middle ring seat, and an inner ring seat arranged coaxially. The outer ring seat is fixed relative to the frame. The middle ring seat is slidably connected to the outer ring seat through a first connecting plate. The inner ring seat is slidably connected to the middle ring seat through a second connecting plate. The anti-wear component is connected to the middle ring seat through a connecting seat. The auxiliary wheel is rotatably mounted on a U-shaped plate through a pin. The U-shaped plate is connected to a sleeve fitted on the inner ring seat. A fixing rod is provided on the inner ring seat. A spiral groove that cooperates with the fixing rod is opened on the inner side wall of the sleeve. When the inner ring seat rotates, the sleeve is driven to rotate relative to the inner ring seat through the cooperation of the fixing rod and the spiral groove. In use, the inner ring seat rotates, and the fixed rod slides relative to it in the spiral groove. The trajectory of the spiral groove forces the sleeve to move along the axis of the inner ring seat while rotating. The rotation of the sleeve drives the U-shaped plate and the auxiliary wheel to revolve. Through the composite hinged seat composed of the outer, middle and inner ring seats, the mechanical structure of the fixed rod and the spiral groove is used to accurately generate the revolution motion, realizing the mechanical precision control of the revolution motion. The structure is stable and the transmission efficiency is high, avoiding the technical problems of synchronization and easy damage of complex control structures and components caused by using multiple motors.

[0010] Furthermore, a seat gear is fixedly connected to the connecting seat, and a driven gear meshing with the seat gear is rotatably connected to the U-shaped plate. The driven gear is connected to the pin shaft, so that when the sleeve rotates, it drives the U-shaped plate to revolve, and the meshing of the driven gear with the seat gear drives the auxiliary wheel to rotate. In use, the rotation of the sleeve drives the U-shaped plate to revolve, and the driven gear mounted on the U-shaped plate meshes with the seat gear fixed on the connecting seat. The revolve motion forces the driven gear to rotate around the seat gear, thereby driving the pin shaft and the auxiliary wheel to rotate. The rotation of the auxiliary wheel can be achieved without an additional power source, which greatly simplifies the transmission system, makes the structure more compact, and reduces energy consumption.

[0011] Furthermore, the cleaning assembly also includes: a sleeve disposed within the protective cavity, the sleeve having two arc-shaped blocks that can slide axially therein, the two arc-shaped blocks being connected by a first spring; a horizontal plate connected to the arc-shaped blocks; the cleaning cylinder being slidably connected to a straight cylinder via a moving rod, the straight cylinder being disposed within the sleeve; when the arc-shaped blocks are axially moved by an external force, the gas inside the straight cylinder is compressed, and the gas enters the gas collection chamber through a channel within the moving rod and exits from the exhaust port. In use, the monofilament passes between the two arc-shaped blocks, squeezing them to move axially, compressing the first spring, causing the arc-shaped blocks to move and push the horizontal plate, which in turn compresses the air inside the straight cylinder via the moving rod. The compressed air enters the gas collection chamber through a channel within the moving rod and is sprayed at high speed onto the surface of the monofilament from the exhaust port. This achieves online, power-free real-time cleaning, reducing equipment energy consumption and dependence on additional facilities, with an ingenious structure and timely response.

[0012] Furthermore, the cleaning assembly also includes an air pressure generating mechanism, which comprises: an airbag disposed within the sleeve; two discs connected to the airbag, one of which is slidably disposed within the sleeve; and a push rod, one end of which is connected to the slidably disposed disc, and the other end of which is provided with a striking block. When the slidably disposed disc is compressed and moved, it compresses the airbag to release air, pushing the push rod to cause the striking block to strike an impact block disposed on the inner wall of the sleeve. In use, the arc-shaped block moves and compresses the airbag, generating an airflow. Simultaneously, the compression pushes the push rod with the disc, causing the striking block at the end of the push rod to strike the fixed impact block. The vibration generated by the impact is transmitted to the cleaning cylinder, shaking off deeply attached dust. This effectively removes firmly attached contaminants, and the combination of airflow and cleaning achieves a deeper and more thorough cleaning.

[0013] Furthermore, the system also includes a guiding mechanism, which is positioned between the stranding mechanism and the winding mechanism. This guiding mechanism comprises: a guide rod parallel to the winding roller; a reciprocating screw parallel to the guide rod, the reciprocating screw being driven to rotate by a motor; and a slider slidably disposed on the guide rod, the reciprocating screw being threadedly connected to the slider, and the slider having guide holes for the stranded cable to pass through. When the winding mechanism is operating, the drive motor of the reciprocating screw starts, converting the rotational motion of the reciprocating screw into the linear reciprocating motion of the slider. The cable passing through the guide holes on the slider is guided, thus winding it evenly and neatly onto the winding roller. This avoids cable overlap and collapse during winding, protects the cable surface, and improves winding quality.

[0014] Furthermore, the wire feeding mechanism includes multiple wire feeding rollers rotatably mounted on a turntable, and each wire feeding roller has a tension adjustment mechanism on one side; the winding roller of the winding mechanism is driven to rotate by a motor. The U-shaped plate is provided with heat dissipation blades, which are inclined to the U-shaped plate to accelerate airflow as the U-shaped plate rotates.

[0015] The beneficial effects of this invention are as follows: When the monofilament wire passes around the detection wheel and guide wheel, tension changes act on the detection wheel, are sensed by the pressure sensor, and converted into an electrical signal. The controller processes the signal and sends a command to the stepper motor. The stepper motor rotates precisely, driving the swing arm and guide wheel to oscillate, tightening or loosening the wire path, thus achieving tension stability. By integrating tension detection with active motor drive adjustment into a single mechanism, a fundamental shift from passive buffering and mechanical adjustment to active, precise, and closed-loop control is achieved. This fundamentally solves the technical problems of inaccurate tension control and slow response in traditional devices, ensuring constant tension during stranding and significantly improving the uniformity and tightness of the stranded wire. During use, after passing through the cleaning component, surface dust is cleaned and blown off by airflow. During stranding, the monofilament wire rolls into contact with the rotating auxiliary wheel, smoothly guiding the stranding point and reducing surface wear and insulation damage during stranding. Simultaneously, it effectively prevents dust from being drawn into the stranded core, improving the electrical performance and quality of the product. The rotation of the sleeve causes the U-shaped plate to revolve. The driven gear mounted on the U-shaped plate meshes with the seat gear fixed on the connecting seat. The revolving motion forces the driven gear to rotate around the seat gear, thereby driving the pin and auxiliary wheel to rotate. The auxiliary wheel can rotate without an additional power source, which greatly simplifies the transmission system, makes the structure more compact, and reduces energy consumption.

The stepper motor 8 is used to drive the swing arm 9 to swing so as to adjust the tension of the monofilament through the guide wheel.

This fundamentally solves the technical problems of inaccurate tension control and slow response in traditional devices, ensuring constant tension during stranding and significantly improving the uniformity and tightness of the strands.

[0020] like Figure 1-9As shown, this embodiment discloses a power cable stranding processing device with a damage-prevention tension adjustment mechanism, including a frame 1, and a wire feeding mechanism 2, a stranding mechanism 3, and a winding mechanism 4 disposed on the frame 1. The frame 1 is also provided with a tension adjustment mechanism 5, which is disposed between the wire feeding mechanism 2 and the stranding mechanism 3, and includes a tension detection component and an active adjustment component.

[0021] For better results, the stranding mechanism 3 includes a stranding base with multiple stranding channels. Several anti-wear components are arranged around the outer periphery of each stranding channel, connecting to the stranding base. These anti-wear components include auxiliary wheels to reduce wear on the monofilament during stranding. The auxiliary wheels have a concave arc surface on their circumference. A protective cavity and a cleaning component 10 along the monofilament's travel path are arranged around the stranding mechanism 3. The cleaning component 10 includes a cleaning cylinder and an air collection chamber communicating with the cleaning cylinder. The air collection chamber has an exhaust port facing the monofilament. The cleaning cylinder removes dust from the surface of the monofilament, which is then discharged through the exhaust port. During use, the surface dust is cleaned and blown off by the airflow after passing through the cleaning component 10. During stranding, the monofilament rolls in contact with the rotating auxiliary wheels, smoothly guiding it to the stranding point. This reduces surface wear and insulation damage during stranding, while effectively preventing dust from being drawn into the stranded core, thus improving the product's electrical performance and quality.

[0022] For better performance, a drive motor is connected to the stranding base. The drive motor is connected to a main gear, which meshes with a first gear ring. The first gear ring drives several of the wear-resistant components. The main gear is connected to a transmission gear system, which drives the auxiliary wheel to rotate. In use, the drive motor starts, rotating the main gear, which in turn rotates the first gear ring. This causes all the wear-resistant components to revolve around the center of the stranding channel. Simultaneously, the main gear transmits power to the auxiliary wheel through the transmission gear system, causing it to rotate. This simple mechanical structure achieves the complex compound motion of the auxiliary wheel, ensuring continuous changes in the contact points of the monofilament wire, achieving uniform wear and effective heat dissipation, and improving the reliability of the equipment.

[0023] For better performance, the twisting seat includes an outer ring seat, a middle ring seat, and an inner ring seat arranged coaxially. The outer ring seat is fixed relative to the frame 1. The middle ring seat is slidably connected to the outer ring seat through a first connecting plate. The inner ring seat is slidably connected to the middle ring seat through a second connecting plate. The anti-wear component is connected to the middle ring seat through a connecting seat. The auxiliary wheel is rotatably mounted on a U-shaped plate through a pin. The U-shaped plate is connected to a sleeve fitted on the inner ring seat. A fixing rod is provided on the inner ring seat. A spiral groove that cooperates with the fixing rod is opened on the inner side wall of the sleeve. When the inner ring seat rotates, the sleeve is driven to rotate relative to the inner ring seat through the cooperation of the fixing rod and the spiral groove. In use, the inner ring seat rotates, and the fixed rod slides relative to it in the spiral groove. The trajectory of the spiral groove forces the sleeve to move along the axis of the inner ring seat while rotating. The rotation of the sleeve drives the U-shaped plate and the auxiliary wheel to revolve.
