An adjustable rubber clamp traction device and method for cable manufacturing

Abstract

This invention relates to the technical field of cable manufacturing, and discloses an adjustable rubber clamp traction device and method for cable manufacturing. To solve the problem of cable rotation during wrapping operations, which leads to tape misalignment, the cable is clamped and transported before wrapping using two vertically arranged clamping tapes. "V" or semi-circular grooves on the outer side of the clamping tapes limit and clamp the cable during transport. The relatively rough contact surfaces between the clamping tapes and the cable utilize increased friction to prevent torsion. Furthermore, when a manufacturing defect such as a protrusion appears on the outer side of the cable, the protrusion forces the clamping tapes to move away from the protrusion. The clamping tapes away from the cable will automatically lock. During this process, the protrusion is ground down by sliding relative to the rough surface of the clamping tape, ultimately achieving the effects of cable grinding and clamping to prevent rotation.

Description

Technical Field

[0001] This invention relates to the technical field of cable manufacturing, and in particular to an adjustable rubber clamp traction device and method for cable manufacturing. Background Technology

[0002] Vertical cable wrapping is a crucial technology in cable manufacturing, widely used in the production processes of various cable products. The core of this process lies in its unique vertical wrapping method. Through the vertical rotation of a wrapping assembly (such as a rotating wrapping head), insulating materials (such as polyester tape, mica tape, etc.) or protective materials (such as non-woven fabric, metal shielding tape, etc.) are evenly and tightly wound around the cable core with precisely controlled tension and angle. This process not only significantly improves the electrical performance of the cable, such as enhancing insulation strength and reducing dielectric loss, but also effectively improves its mechanical properties, such as increasing tensile strength, abrasion resistance, and bending resistance. Simultaneously, it enhances the cable's adaptability to complex environments (such as high temperature, humidity, and chemical corrosion), thereby extending the cable's service life and ensuring its operational stability.

[0003] However, in actual production, when the wrapping assembly rotates, although the cable moves continuously in the horizontal direction through the traction device, the cable is highly susceptible to the dynamic force generated by the rotation of the wrapping assembly, causing it to tend to rotate synchronously with the wrapping assembly. This unintended cable rotation is extremely destructive, directly interfering with the accuracy of the wrapping process and preventing the wrapping material from being evenly wound around the cable core according to the preset wrapping angle and pitch. Specifically, the overlap rate of the wrapping layer may become uncontrolled, failing to meet the requirement of maintaining a certain overlap ratio to ensure the density and integrity of the wrapping layer, resulting in weak points in the wrapping layer; the wrapping material may also shift, deviating from the predetermined wrapping path, causing local wrapping to be too thick or too thin. These problems not only increase raw material waste and production costs but may also cause irreversible damage to the overall performance of the cable, thereby affecting the safety and reliability of the cable in subsequent use. Summary of the Invention

[0004] This invention proposes an adjustable rubber clamp traction device and method for cable manufacturing, which has clamping and anti-rotation properties and cable grinding performance, and can effectively solve the problem mentioned in the background art that the cable rotates during the wrapping operation, which leads to the misalignment of the wrapping tape.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an adjustable rubber clamp traction device for cable manufacturing, comprising: a housing, with a wrapping assembly for wrapping the cable installed inside; a traction assembly fixedly installed in the housing on the cable conveying path; a support slide mounted on the traction assembly, with an adjusting slider symmetrically arranged on its side by an adjusting spring, and a main pressure roller group symmetrically arranged on the side of the adjusting slider by a pressure belt drive, the two pressure belts being used to clamp the cable to prevent rotation; a detection slide, oriented on the side of the adjusting slider via a guide rail, with a permanent magnet mounted on its outer side and an electromagnet assembly on the side of the adjusting slider having magnetic surfaces facing each other; when a protrusion defect appears on the side of the cable, the protrusion pushes the pressure belt away from the support slide, and the start switch on the outside of the adjusting slider at this time connects the electromagnet assembly and generates magnetism that attracts the permanent magnet, using magnetic attraction to cause the detection push rod mounted at the end of the detection slide to abut against the limit frame, thereby limiting the movement of the pressure belt, and the relative movement of the pressure belt and the protrusion realizes the grinding work.

[0006] Furthermore, the traction assembly includes a support base fastened to the middle of the chassis, a guide seat installed on the top of the support base, and an adjusting screw assembly in the guide seat controlling the up and down movement of the support slide to achieve horizontal alignment between the clamping part of the wire clamping tape and the cable.

[0007] Furthermore, a guide groove is provided on the outer side of the pressure strip.

[0008] Furthermore, a detection spring is installed between the detection push rod and the detection slide. The spring force pushes the detection push rod against the inside of the pressure strip, so that the pressure strip is always kept taut.

[0009] Furthermore, drive teeth are equidistantly arranged in the middle of the inner side of the pressure belt, and the main pressure roller group is arranged coaxially by gears and pulleys. The pulleys are fixed at both ends of the gears, and the gears and drive teeth mesh and transmit power.

[0010] Furthermore, the limiting frame includes: a drive linear section, which is parallel to the guide rail on the detection slide; a return slope section, which is fixed to the left end of the drive linear section; and a detection slope section, which is fixed to the right end of the drive linear section, and the detection slope section and the return slope section are parallel to each other.

[0011] Furthermore, a stop switch is fixedly installed on the side of the adjusting slider, located below the bottom of the detection ramp. When the stop switch is pressed, the operation stops and an alarm is triggered.

[0012] A method of using an adjustable rubber clamp traction device for cable manufacturing includes the following steps:

[0013] S1. After passing through the wire clamping tape, the cable is threaded into the wrapping assembly for wrapping.

[0014] S2. When the cable is pulled continuously from left to right by the traction device, the cable is clamped against rotation by the guide grooves on the outer side of the two pressure strips.

[0015] S3. During the forward transport of the cable, the pressure belt rotates synchronously; the continuous rotation of the pressure belt enables continuous anti-rotation clamping of the cable.

[0016] The present invention has the following beneficial effects:

[0017] The present invention provides an adjustable rubber clamp traction device and method for cable manufacturing. Before the cable is wrapped, it is clamped and transported by two vertically arranged pressure strips. The “V” or semi-circular grooves on the outer side of the pressure strips can limit the clamping and transport of the cable. Based on the relatively rough contact surface between the pressure strips and the cable, the increased friction is used to prevent torsion.

[0018] Furthermore, when a manufacturing defect such as a protrusion appears on the outside of the cable, the protrusion will force the clamping strip to move away from the protrusion. The clamping strip away from the cable will lock itself. During this process, the protrusion is ground by sliding relative to the rough surface on the clamping strip, thus achieving the effect of grinding the cable and clamping to prevent rotation.

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Example 1, please refer to Figure 1 It can be seen that the chassis 1 provides support and protection for the entire device. A wrapping assembly 3 is movably mounted on one side of the inner part of the chassis 1. The wrapping assembly 3 typically consists of a rotating disc, a guide belt device, and a tension control device. The rotating disc is driven by a motor, causing the wrapping material to be wound around the cable 2 at a certain angle and speed. Figure 1 As can be seen from the diagram, cable 2 enters from the left side of the chassis 1, passes through the wrapping assembly 3, and exits from the right side. The power for cable 2 is provided by a traction device, which is not shown in the diagram. The traction device is mainly responsible for the horizontal movement of cable 2, ensuring the continuity and stability of the wrapping process. The traction speed must match the rotational speed of the wrapping assembly 3 to ensure the uniformity of the wrapping pitch.

[0033] However, during the actual wrapping process, cable 2 is prone to rotation, leading to misalignment of the wrapping tape. To address this issue, this embodiment 1 includes a traction assembly 4 fixedly installed inside the chassis 1 along the cable 2's transport path. (See reference...) Figure 4 and Figure 6It is easy to see that the traction assembly 4 includes a support base 401 bolted to the middle of the housing 1, which provides support and limits the entire traction assembly 4. A guide seat 402, bolted to the top of the support base 401, has symmetrically arranged slide rails on its sides, which restrict the support slide 5 to reciprocating up and down. The position of the support slide 5 is controlled by an adjusting screw assembly 403 located in the middle of the guide base 402. The adjusting screw assembly 403 includes an adjusting screw and a lead screw, with the lead screw threadedly connected to the support slide 5. The adjusting nut and the lead screw are coaxially fastened. In practical applications, the operator can adjust and lock the up and down movement of the support slide 5 by turning the adjusting nut.

[0034] To ensure the clamping and anti-rotation of cable 2 during transportation, from Figure 6 It can be seen that two adjusting sliders 6 are symmetrically arranged on the side of the support slide 5, and the adjusting sliders 6 are guided by the round rod. An adjusting spring 600 is installed between the support slide 5 and the adjusting sliders 6 on the outer side of the round rod. Under normal conditions, the spring force of the adjusting spring 600 will force the two adjusting sliders 6 to move closer together. Main pressure roller groups 7 are symmetrically arranged on the side of the adjusting sliders 6. The two main pressure roller groups 7 are connected by a pressure belt 9. Since there are two pressure belts 9, and the two pressure belts 9 are pressed together due to the relative proximity of the adjusting sliders 6, the cable 2 is ultimately clamped. Figure 7 The state is shown. It should be noted that a guide groove is provided on the outer side of the clamping tape 9. This guide groove is used to securely clamp the cable 2. Generally, the inner side of the guide groove is relatively rough (like a sandblasted surface) to increase the friction between it and the cable 2. The guide groove is preferably a semi-circular groove, such as... Figure 7 As shown, when the guide grooves on the outer sides of the two clamping strips 9 are joined together, they can clamp the cable 2. The guide grooves are not limited to this; they can also be V-shaped grooves with an angle of 60°-90°, etc.

[0035] In practical applications, cable 2 passes through the pressure band 9 and then enters the wrapping assembly 3 for wrapping. When cable 2 is pulled by the traction device, it can move continuously from left to right. During this process, the guide grooves on the outer sides of the two pressure bands 9 are used to clamp the cable 2 to prevent rotation, ensuring that the pressure bands 9 rotate synchronously as the cable 2 is conveyed forward. By continuously rotating the pressure bands 9, continuous anti-rotation clamping of the cable 2 is achieved. Figure 8 The state shown.

[0036] from Figure 2 , Figure 3 and Figure 6As can be seen, the adjusting slider 6 is equipped with auxiliary pressure rollers 8 that support the cable clamping strip 9. Multiple auxiliary pressure rollers 8 are available, and the number can be adjusted according to actual usage requirements. The auxiliary pressure rollers 8 push the cable clamping strip 9 to clamp the cable 2, further enhancing the clamping and anti-rotation strength of the cable 2.

[0037] Example 2 is a further improvement on Example 1. During the actual wrapping process, manufacturing defects such as protrusions may appear on the outer side of cable 2 due to factors such as the manufacturing process. These protrusions prevent the wrapping tape from tightly adhering to the cable surface during wrapping, forming cavities or wrinkles and reducing the mechanical protection effect of the wrapping layer. To prevent such problems, combined with… Figure 3-Figure 6 It can be seen that the side of the adjusting slider 6 has a detection slide 12 that moves laterally back and forth along the guide rail, and a permanent magnet 121 is fixedly installed on the side of the detection slide 12. The permanent magnet 121 is generally made of ferrite or neodymium iron boron. Correspondingly, an electromagnet assembly 15 is fixedly installed on the side of the adjusting slider 6, opposite to the magnetic surface of the permanent magnet 121. Its specifications and models can be selected according to actual usage requirements. Under normal conditions, the electromagnet assembly 15 is in a de-energized state. More specifically, combined with Figure 6 It can be seen that a start switch 16 is fixedly installed on the outside of the adjusting slider 6. Under normal conditions, the start switch 16 is pushed by the elastic force of the adjusting spring 600, forcing it to the middle of the support slide 5. At this time, the pressed start switch 16 prevents the electromagnet assembly 15 from being energized. When the start switch 16 moves away from the support slide 5 and is released from pressure, the electromagnet assembly 15 is energized and generates magnetism that attracts the permanent magnet 121. The magnetic attraction between the permanent magnet 121 and the electromagnet assembly 15 is used to make the detection slide 12 move closer to the electromagnet assembly 15.

[0038] Furthermore, a detection push rod 13 is movably mounted at the end of the detection slide 12, facing the inner side of the pressure band 9. A detection spring 130 is provided between the detection push rod 13 and the detection slide 12. The detection push rod 13 is forced to always press against the inner side of the pressure band 9 by the elastic force of the detection spring 130. At the same time, a limit frame 11 is fastened to the side of the adjusting slider 6 by bolts. When the detection push rod 13 presses against the limit frame 11, the rotation of the pressure band 9 can be restricted by the detection push rod 13. The advantage of this design is that when the pressure band 9 is relatively away from the cable 2 due to the protrusion of the cable 2, the pressure band 9 after moving away from the cable 2 will activate the electromagnet assembly 15 through the start switch 16. Under the magnetic attraction between the permanent magnet 121 and the electromagnet assembly 15, the detection push rod 13 presses against the limit frame 11, which increases the strength of the detection push rod 13 pressing against the pressure band 9, thereby restricting the rotation of the pressure band 9. Cable 2 is constantly moving forward under the traction device. Therefore, when cable 2 and the pressure band 9 move relative to each other, the rough surface of the guide groove in the pressure band 9 is used to grind the protrusions on cable 2, preventing the protrusions on cable 2 from affecting subsequent wrapping work. More detailed, from... Figure 3-Figure 6 It can be seen that drive teeth 10 are arranged in a ring at equal intervals in the middle of the inner side of the pressure belt 9. Correspondingly, the main pressure roller group 7 consists of a gear and a pulley arranged coaxially, with the pulley fixed at both ends of the gear. The meshing transmission between the gear and the drive teeth 10 increases the transmission strength between the main pressure roller group 7 and the pressure belt 9. Furthermore, from... Figures 4-6 As can be seen, the limiting frame 11 consists of a return ramp 111, a drive linear section 112, and a detection ramp 113. The drive linear section 112 is relatively horizontal and parallel to the guide rail on the detection slide 12. The return ramp 111 is fixedly disposed at the left end of the drive linear section 112, and the angle between the return ramp 111 and the drive linear section 112 is approximately 135°. The detection ramp 113 is disposed at the right end of the drive linear section 112, and the detection ramp 113 is parallel to the return ramp 111. The advantage of this design is that... Figure 4 and Figure 5 As can be seen, the drive tooth 10 is an isosceles trapezoid. When the top of the detection push rod 13 abuts against the drive straight section 112, the detection push rod 13 is inserted between two adjacent drive teeth 10. The drive straight section 112 restricts the upward movement of the detection push rod 13, and the detection push rod 13 moves synchronously with the pressure band 9. If there is no protrusion defect in the cable 2 between the two pressure bands 9 at this time, the adjustment spring 600 pushes the start switch 16 to the middle of the support slide 5, and stops the electromagnet assembly 15 from working. Afterwards, when the cable 2 moves forward under the traction device, it... Figures 3-5 and Figure 8As shown in the motion diagram, the lower pressure band 9 moves to the right due to the movement of cable 2. The pressure band 9 then drives the detection push rod 13 to move to the left along the drive line 112 until the detection slide 12 reaches the left limit of the guide rail. At this point, the detection push rod 13 is below the return slope 111. Driven by cable 2, the lower pressure band 9 continues to rotate clockwise. During this process, the drive tooth 10 tends to push the detection push rod 13 upwards. The return slope 111 does not prevent the detection push rod 13 from moving upwards until the drive tooth 10 passes the detection push rod 13. As the pressure band 9 continues to move, the detection push rod 13, under the force of the adjusting spring 600, will push against the next drive tooth 10.

[0039] Similarly, if cable 2 bulges and passes through the wire clamping tape 9, combined with... Figures 3-5 and Figure 9 As shown in the motion diagram, taking the lower pressure strip 9 under pressure as an example, the upper pressure strip 9 is adjusted in the same way after being pressed. The pressure strip 9 is pushed downward by the protrusion, causing the lower start switch 16 to be released from pressure. The electromagnet assembly 15 is turned on and generates magnetism that attracts the permanent magnet 121. The permanent magnet 121 pulls the detection slide 12 to the right, causing the detection push rod 13 to enter the drive linear section 112. At this time, because the drive linear section 112 restricts the upward movement of the detection push rod 13 and keeps it inserted between the two drive teeth 10, as the detection slide 12 moves to the right, the lower pressure strip 9 will rotate counterclockwise. The direction of movement of the pressure strip 9 at this time is opposite to the direction of movement of the cable 2. The rough surface on the outer side of the pressure strip 9 can grind the protrusion on the outer side of the cable 2 until the protrusion on the outer side of the cable 2 is completely eliminated, and no pushing force will be applied to the lower pressure strip 9. The lower adjusting slider 6 is pushed upward by the adjusting spring 600, and the start switch 16 is pressed again, and the electromagnet assembly 15 stops working. Then, the cable 2 pulls the pressure band 9 to rotate clockwise again, and the pressure band 9 drives the detection push rod 13 to move to the left along the drive line 112 to complete the reset.

[0040] In practical applications, the guide groove on the outer side of the clamping band 9 clamps the cable 2 to prevent rotation. At this time, the two adjusting sliders 6 are brought closer together by the elastic force of the adjusting spring 600. The start switch 16 abuts against the support slide 5 and prevents the electromagnet assembly 15 from being turned on, causing the outer sides of the two clamping bands 9 to come together. As the cable 2 is pulled by the traction device, it is wrapped by the wrapping assembly 3 and then output from the right side of the housing 1. Figure 8The state shown is as follows. Simultaneously, under normal conditions, the lower pressure strip 9 rotates clockwise. Because the detection push rod 13 is pushed towards the pressure strip 9 by the force of the detection spring 130, the pressure strip 9 drives the detection push rod 13 to move synchronously. This forces the detection push rod 13 to move the detection slide 12 and the permanent magnet 121 away from the electromagnet assembly 15 until the detection slide 12 reaches its left limit. At this point, the detection push rod 13 is located below the return slope 111. Driven by the force of the detection spring 130, the detection push rod 13 is always pressed against the inside of the pressure strip 9. Therefore, when the pressure strip 9 is working, the detection push rod 13 pushes the pressure strip 9 to remain in a taut state. Initially, the pressure band 9 is relatively new and its tension is relatively tight. When the pressure band 9 moves clockwise, the outer inclined surface of the drive tooth 10 forces the detection push rod 13 to move upward. After the detection push rod 13 moves upward, it will move towards the return inclined part 111 and will not hinder the movement of the pressure band 9.

[0041] As cable 2 is continuously pulled by the traction device, when a manufacturing protrusion defect exists on cable 2, the protrusion passes through the pressure band 9. Since the pressure band 9 has a certain length, the actual usable length can be adjusted according to usage requirements. Within the length range set by the pressure band 9, the protrusion defect on cable 2 needs to be eliminated. Specifically, when the protrusion is on the pressure band 9, it will cause the pressure band 9 to tend to move relatively away from cable 2. Figure 9 Taking the presence of a protrusion on the lower side of cable 2 as an example, the protrusion pushes the lower pressure strip 9 downwards, forcing the adjusting slider 6 to descend and compress the adjusting spring 600. The start switch 16 will also disengage from the support slide 5. Releasing the pressure, the start switch 16 will activate the electromagnet assembly 15, causing it to attract the permanent magnet 121. At this time, the attracted permanent magnet 121 will move to the right, simultaneously pulling the detection slide 12 along the guide rail to the right. When the top of the detection slide 12 enters the drive linear section 112 from the return slope 111, the drive linear section 112 restricts the detection push rod 13 from moving upwards, ultimately forcing the detection push rod 13 to remain inserted between the drive teeth 10. When the detection slide 12 is attracted to move to the right by the permanent magnet 121 and the electromagnet assembly 15, on the one hand, the detection push rod 13 restricts the rotation of the pressure band 9; on the other hand, when the detection slide 12 pulls the detection push rod 13 to move to the right, the detection push rod 13 can pull the pressure band 9 to rotate counterclockwise. At this time, the two pressure bands 9 move in the same direction, and the lower pressure band 9 moves in the opposite direction to the cable 2. Figure 9As shown in the diagram. Since the cable 2 only contacts the lower pressure strip 9 based on the protrusion, when the pressure strip 9 and the cable 2 move relative to each other, the rough surface on the outer side of the pressure strip 9 is not only limited to clamping and limiting the cable 2, but also can be used to grind the protrusion at a fixed point, ensuring that the cable 2 conveyed to the wrapping assembly 3 will not have protrusion defects, and ultimately ensuring the quality of the wrapping.

[0042] When the detection slide 12 moves to the right, it causes the detection push rod 13 to move to the detection ramp 113. On one hand, this further pushes the detection push rod 13 towards the pressure band 9, keeping the pressure band 9 taut. On the other hand, the pressure band 9 restricts the detection push rod 13 from crossing the detection ramp 113, thus limiting its further movement towards the electromagnet assembly 15, maintaining the position of the detection push rod 13. Since the detection push rod 13 continues to extend at this time, the detection push rod 13, now on the right, still restricts the movement of the pressure band 9. This ensures that even when the protrusion on the cable 2 and the stationary pressure band 9 are in relative motion, grinding can still be performed on the protrusion to address manufacturing defects.

[0043] At the same time, from Figure 5 and Figure 6 As can be seen, a stop switch 14 is fixedly installed on the side of the adjusting slider 6, located below the bottom of the detection ramp 113. When the stop switch 14 is pressed, it can send an electrical signal to the control system, thereby stopping the operation and triggering an alarm. This is because the tension of the pressure band 9 decreases over time. Under normal conditions, when the detection slide 12 moves to the right side due to the magnetic force between the permanent magnet 121 and the electromagnet assembly 15, the detection push rod 13 will abut against the slope of the detection ramp 113. The normally tensioned pressure band 9 will restrict the movement of the detection push rod 13 along the detection ramp 113, preventing the detection slide 12 from contacting the stop switch 14. When the tension of the cable clamping tape 9 decreases due to prolonged use, the push rod 13 pushes it downwards, further increasing the downward extension of the push rod 13. This also increases the distance the push rod 13 travels to the right along the detection ramp 113, ultimately causing the detection slide 12 to reach the stop switch 14. The stop switch 14 then sends a signal to the control system, stopping the wrapping and triggering an alarm, thus alerting the operator that the cable clamping tape 9 needs replacement. This detection method ensures that the cable clamping tape 9 is functioning correctly, greatly guaranteeing its clamping and anti-rotation effect on the cable 2 as described in this application.
