Description

Technical Field

[0001] The present invention relates to the technical field related to cable production and manufacturing, and in particular to an adjustable rubber clamp traction device for cable manufacturing and a method thereof. Background Art

[0002] The vertical cable wrapping process is a crucial technical tool in cable manufacturing and is widely used in the production 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 cable's electrical performance, such as enhancing insulation strength and reducing dielectric loss, but also effectively enhances the cable's mechanical properties, such as increasing tensile strength, abrasion resistance, and bending resistance. It also 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 continues to move horizontally through the traction device, due to the torque transmission generated by the rotation of the wrapping assembly, the cable is extremely susceptible to the influence of this dynamic force and tends to rotate synchronously with the wrapping assembly. This unexpected cable rotation is extremely destructive. It will directly interfere with the accuracy of the wrapping process, resulting in the wrapping material not being evenly wound on the cable core according to the preset wrapping angle and pitch. Specifically, the overlap rate of the wrapping layer may be out of control, and the requirement to maintain a certain overlap ratio to ensure the density and integrity of the wrapping layer cannot be achieved, resulting in weak links in the wrapping layer; the wrapping material may also shift and deviate from the established wrapping path, resulting in local wrapping that is too thick or too thin. These problems not only increase the loss of raw materials 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] The present invention proposes an adjustable rubber clamp traction device and method for cable manufacturing, which has clamping anti-rotation and cable grinding performance, and can effectively solve the problem of cable rotation during wrapping operation mentioned in the above background technology, thereby causing tape misalignment.

[0005] To achieve the above-mentioned purpose, the present invention adopts the following technical scheme: an adjustable rubber clamp traction device for cable manufacturing, comprising: a chassis, on the inside of which is installed a wrapping assembly for wrapping the cable; a traction assembly located on the cable conveying path is fixedly installed in the chassis; a supporting slide, mounted on the traction assembly, with adjusting sliders pushed by adjusting springs symmetrically arranged on the sides, and main pressure wheel groups connected by wire pressing belts symmetrically arranged on the sides of the adjusting slider, and the two wire pressing belts can be used to clamp and prevent the cable from rotating; a detection slide, mounted on the side of the adjusting slider through a guide rail, and a permanent magnet mounted on the outside of the detection slide and a magnetic surface of the electromagnet assembly on the side of the adjusting slider facing each other; when a protrusion defect occurs on the side of the cable, the protrusion pushes the wire pressing belt relatively away from the supporting slide, and the starting switch on the outside of the adjusting slider turns on the electromagnet assembly and generates magnetism attracted by the permanent magnet, and the detection push rod mounted on the end of the detection slide is pushed against the limit frame by magnetic attraction, thereby limiting the movement of the wire pressing belt, and the relative movement of the wire pressing belt and the protrusion realizes grinding.

[0006] Furthermore, the traction assembly includes a support base fastened to the middle of the chassis, a guide base is installed on the top of the support base, and the adjustment screw assembly in the guide base controls the up and down movement of the support slide to achieve horizontal alignment of the clamping part of the wire pressing belt with the cable.

[0007] Furthermore, a guide groove is provided on the outer side of the wire pressing belt.

[0008] Furthermore, a detection spring is provided between the detection push rod and the detection slide, and the elastic force of the detection spring pushes the detection push rod to the inner side of the wire pressing belt, so that the wire pressing belt always maintains a tensioned state.

[0009] Furthermore, driving teeth are evenly spaced in the middle of the inner side of the crimping belt, and the main crimping wheel group is coaxially arranged with a gear and a pulley, the pulley is fixed at both ends of the gear, and the gear and the driving teeth are meshed for transmission.

[0010] Furthermore, the limit frame includes: a driving straight portion, which is relatively parallel to the guide rail on the detection slide; a return inclined portion, which is fixed at the left end of the driving straight portion; and a detection inclined portion, which is fixed at the right end of the driving straight portion, and the detection inclined portion and the return inclined portion are relatively parallel.

[0011] Furthermore, a stop switch located below the bottom of the detection inclined portion is fixedly installed on the side of the adjustment slider, and the work is stopped and an alarm is triggered when the stop switch is pressed.

[0012] A method for using an adjustable rubber clamp traction device for cable manufacturing, comprising the following steps: S1. After passing through the wire crimping tape, the cable is passed into the wrapping assembly for wrapping.

[0013] S2. When the cable is pulled by the traction device and moves continuously from left to right, the guide grooves on the outside of the two pressing belts are used to clamp the cable to prevent rotation.

[0014] S3. The cable pressing belt is driven to rotate synchronously during the forward conveyance of the cable; the cable pressing belt is continuously rotated to achieve continuous anti-rotation clamping of the cable.

[0015] The present invention has the following beneficial effects: The present invention provides an adjustable rubber clamp traction device and method for cable manufacturing. Before the cable is wrapped, two upper and lower pressing belts are used to clamp and convey the cable. The "V" or semicircular groove provided on the outer side of the pressing belt can limit the clamping and conveying of the cable, and the contact surface between the pressing belt and the cable is relatively rough, so as to achieve anti-twisting by utilizing the increased friction force.

[0016] Not only that, when a protruding manufacturing defect appears on the outside of the cable, the protrusion will force the wire pressing belt to move away from the protrusion, and the wire pressing belt away from the cable will lock automatically. During this process, the protrusion and the rough surface on the wire pressing belt slide relative to each other to achieve the grinding of the protrusion, and ultimately achieve the effect of cable grinding and clamping to prevent rotation.

DETAILED DESCRIPTION

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0021] For example 1, please refer to Figure 1 It can be seen that the chassis 1 can provide support and protection for the entire device. A wrapping assembly 3 is movably installed on one side of the inner side of the chassis 1. The wrapping assembly 3 is generally composed of a rotating disk, a belt guide device and a tension control device. The rotating disk is driven by a motor to drive the wrapping material to be wound around the cable 2 at a certain angle and speed. Figure 1 As can be seen, cable 2 enters the left side of chassis 1, passes through wrapping assembly 3, and exits the right side. Power for cable 2 is provided by a traction device (not shown). This traction device is primarily responsible for horizontally moving cable 2, ensuring continuity and stability during the wrapping process. The traction speed must match the rotational speed of wrapping assembly 3 to ensure uniform wrapping pitch.

[0022] However, in the actual wrapping process, the cable 2 is prone to self-rotation, resulting in the problem of tape misalignment during the wrapping process. In order to solve this problem, the present embodiment 1 is based on the inner side of the chassis 1, which is fixed with a traction component 4 located on the cable 2 conveying path. Figure 4 and Figure 6It is not difficult to see that the traction assembly 4 includes a support base 401 fastened to the middle of the chassis 1 with bolts, and the support base 401 provides support and limitation for the entire traction assembly 4. A guide base 402 fastened with bolts is provided on the top of the support base 401, and slide rails are symmetrically arranged on the sides of the guide base 402, which limit the support slide 5 to only be able to reciprocate up and down along the guide rails. The position of the support slide 5 is controlled by the adjustment screw assembly 403 provided in the middle of the guide base 402. The adjustment screw assembly 403 includes an adjusting screw and a screw rod, wherein the screw rod is threadedly connected to the support slide 5, and the adjustment nut and the screw rod are coaxially tightened. In actual application, the operator can adjust the up and down movement of the support slide 5 and self-lock it by turning the adjustment nut.

[0023] In order to ensure that the cable 2 is clamped and prevented from rotating during transportation, 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, and an adjusting spring 600 is installed on the outer side of the round rod between the support slide 5 and the adjusting slider 6. Under normal circumstances, the elastic force of the adjusting spring 600 will force the two adjusting sliders 6 to be relatively close. The main pressure wheel group 7 is symmetrically arranged on the side of the adjusting slider 6. The outer sides of the two main pressure wheel groups 7 are connected by a wire pressing belt 9. Since there are two wire pressing belts 9 and the two wire pressing belts 9 are attached together due to the relative proximity of the adjusting slider 6, the cable 2 is finally clamped. Figure 7 It should be noted that a guide groove is provided on the outside of the wire pressing belt 9, and the guide groove is used to fasten and clamp the cable 2. Generally speaking, the inside of the guide groove is relatively rough (such as sand products) to increase the friction between the cable 2 and the guide groove. The guide groove is preferably a semicircular groove, such as Figure 7 As shown, when the guide grooves on the outside of the two pressing belts 9 are fitted together, the cable 2 can be clamped. The guide groove is not limited thereto, and can also be a V-shaped groove with an angle of 60°-90°, etc.

[0024] In actual use, the cable 2 passes through the wire pressing belt 9 and enters the wrapping assembly 3 for wrapping. When the cable 2 is pulled by the traction device, the cable 2 can be continuously moved from left to right. In this process, the guide grooves on the outside of the two wire pressing belts 9 are used to prevent the cable 2 from rotating, ensuring that the wire pressing belts 9 can rotate synchronously during the forward transportation of the cable 2. The continuous rotation of the wire pressing belt 9 can achieve continuous anti-rotation clamping of the cable 2, that is, Figure 8 Status shown.

[0025] from Figure 2 、 Figure 3 and Figure 6As can be seen in the figure, the adjusting slider 6 is equipped with auxiliary pressure rollers 8 that can support the wire pressing belt 9. The number of auxiliary pressure rollers 8 can be adjusted according to actual use requirements. The auxiliary pressure rollers 8 push the wire pressing belt 9 to clamp the cable 2, further enhancing the clamping and anti-rotation strength of the cable 2.

[0026] The second embodiment is a further improvement on the first embodiment. In the actual wrapping process, due to factors such as the manufacturing process, there will be manufacturing defects such as bulges on the outside of the cable 2. These bulges will cause the wrapping tape to be unable to fit tightly to the cable surface during the wrapping process, forming cavities or wrinkles, and reducing the mechanical protection effect of the wrapping layer. In order to prevent such problems from occurring, combined with Figure 3-Figure 6 It can be seen that the side of the adjustment slider 6 has a detection slide 12 that moves back and forth laterally through the guide rail, and the side of the detection slide 12 is fixedly installed with a permanent magnet 121. The permanent magnet 121 is generally made of ferrite or neodymium iron boron. In contrast, the side of the adjustment slider 6 is fixedly installed with an electromagnet assembly 15 opposite to the magnetic surface of the permanent magnet 121. Its specifications and models can be purchased according to actual usage needs. Under normal circumstances, the electromagnet assembly 15 is in a power-off state. More specifically, combined with Figure 6 As can be seen, a start switch 16 is fixedly mounted on the outside of the adjustment slider 6. Under normal conditions, the elastic force of the adjustment spring 600 pushes the start switch 16 against the middle of the support slide 5. At this time, the compressed start switch 16 prevents the electromagnet assembly 15 from being energized. When the start switch 16 moves away from the support slide 5 and the pressure is released, the electromagnet assembly 15 is energized and generates a magnetic attraction with the permanent magnet 121. The magnetic attraction between the permanent magnet 121 and the electromagnet assembly 15 causes the detection slide 12 to move closer to the electromagnet assembly 15.

[0027] Furthermore, a detection push rod 13 is movably mounted at the end of the detection slide 12, facing the inner side of the wire pressing belt 9. A detection spring 130 is provided between the detection push rod 13 and the detection slide 12. The detection push rod 13 is pushed by the elastic force of the detection spring 130 to always press against the inner side of the wire pressing belt 9. At the same time, a limit frame 11 is provided on the side of the adjustment slider 6, which is fastened with bolts. When the detection push rod 13 presses against the limit frame 11, the rotation of the wire pressing belt 9 can be restricted by the detection push rod 13. The advantage of this design is that when the wire pressing belt 9 is relatively away from the cable 2 due to the protrusion of the cable 2, the wire pressing belt 9 away from the cable 2 activates 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 is pressed against the limit frame 11, resulting in an increase in the strength of the detection push rod 13 pressing against the wire pressing belt 9, thereby restricting the rotation of the wire pressing belt 9. The cable 2 is always moved forward by the traction device. Therefore, when the cable 2 and the wire pressing belt 9 move relative to each other, the rough surface of the guide groove in the wire pressing belt 9 is used to grind the protrusions on the cable 2, so as to avoid the protrusions on the cable 2 affecting the subsequent wrapping work. Figure 3-Figure 6 It can be seen that the driving teeth 10 are arranged in an equidistant ring in the middle of the inner side of the wire pressing belt 9. Correspondingly, the main pressure wheel group 7 is coaxially arranged with a gear and a pulley. The pulley is fixed at both ends of the gear. The meshing transmission between the gear and the driving teeth 10 is used to increase the transmission strength between the main pressure wheel group 7 and the wire pressing belt 9. Figure 4-Figure 6 It can be seen that the limit frame 11 is composed of a return bevel 111, a driving straight portion 112 and a detection bevel 113, wherein the driving straight portion 112 is relatively horizontal and relatively parallel to the guide rail on the detection slide 12, and the return bevel 111 is fixedly set at the left end of the driving straight portion 112, and the angle between the return bevel 111 and the driving straight portion 112 is about 135 degrees. The detection bevel 113 is set at the right end of the driving straight portion 112, and the detection bevel 113 and the return bevel 111 are relatively parallel. The advantage of this design is that Figure 4 and Figure 5 It can be seen that the shape of the driving teeth 10 is an isosceles trapezoid. When the top of the detection push rod 13 reaches the driving straight portion 112, the detection push rod 13 is inserted between two adjacent driving teeth 10. The driving straight portion 112 can limit the upward movement of the detection push rod 13, and the detection push rod 13 moves synchronously with the wire pressing belt 9. If there is no protrusion defect in the cable 2 between the two wire pressing belts 9 at this time, the adjustment spring 600 pushes the start switch 16 to the middle of the support slide 5, and the electromagnet assembly 15 stops working. Afterwards, when the cable 2 is pulled forward by the traction device, Figure 3-Figure 5 and Figure 8As shown in the motion state in the figure, the pressing belt 9 at the bottom moves to the right due to the cable 2, and the pressing belt 9 will drive the detection push rod 13 to move to the left along the driving straight portion 112 until the detection slide 12 moves to the left limit of the guide rail. The detection push rod 13 is now below the return inclined portion 111. The pressing belt 9 below is driven by the cable 2 and will continue to rotate clockwise. During this process, the driving tooth 10 will tend to push the detection push rod 13 upward. The return inclined portion 111 will not prevent the detection push rod 13 from moving upward until the driving tooth 10 passes the detection push rod 13. As the pressing belt 9 continues to move, the detection push rod 13 is subjected to the elastic force of the adjustment spring 600 and will press against the next driving tooth 10.

[0028] Similarly, if the cable 2 is bulged and passes through the pressure tape 9, Figure 3-Figure 5 and Figure 9 As shown in the motion state in the figure, taking the compression of the lower wire pressing belt 9 as an example, the upper wire pressing belt 9 is adjusted in the same manner after being compressed. The wire pressing belt 9 is pushed downward by the protrusion and the starting switch 16 below is released from the compression. The electromagnet assembly 15 is connected and generates a magnetic attraction with the permanent magnet 121. The permanent magnet 121 pulls the detection slide 12 to the right and causes the detection push rod 13 to enter the driving straight portion 112. At this time, because the driving straight portion 112 limits the detection push rod 13 from moving upward and makes it always inserted between the two driving teeth 10, as the detection slide 12 moves to the right, the wire pressing belt 9 below is rotated counterclockwise. The direction of movement of the wire pressing belt 9 at this time is opposite to the direction of movement of the cable 2. The rough surface on the outside of the wire pressing belt 9 can grind the protrusion on the outside of the cable 2 until the protrusion on the outside of the cable 2 is completely eliminated, and no thrust is applied to the wire pressing belt 9 below. The adjusting slide 6 below is pushed upward by the adjusting spring 600 and causes the starting switch 16 to be compressed again, and the electromagnet assembly 15 stops working. Then, the cable 2 pulls the wire pressing belt 9 to rotate clockwise again, and the wire pressing belt 9 drives the detection push rod 13 to move to the left along the driving straight portion 112 to complete the reset.

[0029] In actual use, the guide groove on the outside of the wire pressing belt 9 clamps the cable 2 to prevent rotation. At this time, the two adjustment sliders 6 are moved closer to each other by the elastic force of the adjustment spring 600, the start switch 16 is pressed against the support slide 5 and the electromagnet assembly 15 is not turned on, and the two outer sides of the wire pressing belts 9 are pressed together. As the cable 2 is pulled by the traction device, the cable 2 is wrapped by the wrapping assembly 3 and output from the right side of the chassis 1. Figure 8At the same time, under normal conditions, the wire pressing belt 9 located below rotates clockwise. Since the detection push rod 13 is pushed toward the wire pressing belt 9 by the elastic force of the detection spring 130, the wire pressing belt 9 will drive the detection push rod 13 to move synchronously, forcing the detection push rod 13 to drive the detection slide 12 and the permanent magnet 121 to move away from the electromagnet assembly 15 until the detection slide 12 moves to the left limit. At this time, the detection push rod 13 is located below the return bevel 111. The detection push rod 13 is pushed by the elastic force of the detection spring 130 to always press against the inner side of the wire pressing belt 9. Therefore, when the wire pressing belt 9 is working, the detection push rod 13 pushes the wire pressing belt 9 to always be in a tensioned state. Initially, the wire pressing belt 9 is relatively new and its tension is relatively tight. When the wire pressing belt 9 moves clockwise, the outer inclined surface of the driving tooth 10 forces the detection push rod 13 to move upward. After moving upward, the detection push rod 13 will move toward the return inclined portion 111 and will not hinder the movement of the wire pressing belt 9.

[0030] As the cable 2 is continuously pulled by the traction device, when there is a manufacturing protrusion defect on the cable 2, the protrusion passes through the wire pressing belt 9. Since the wire pressing belt 9 has a certain length, the actual use length can be adjusted according to the needs of use. Within the length range set by the wire pressing belt 9, the protrusion defect on the cable 2 needs to be eliminated. Specifically, when the protrusion is on the wire pressing belt 9, it will cause the wire pressing belt 9 to have a tendency to move relatively away from the cable 2, thereby Figure 9 Taking the protrusion on the lower side of the cable 2 as an example, the protrusion will push the wire pressing belt 9 below to move downward, forcing the adjustment slider 6 to move downward and compress the adjustment spring 600, and the starting switch 16 will also be disengaged from the support slide 5. After the pressure is released, the starting switch 16 will start the electromagnet assembly 15 and cause the electromagnet assembly 15 to generate magnetism that attracts the permanent magnet 121. At this time, the attracted permanent magnet 121 will move to the right and simultaneously pull the detection slide 12 to move to the right along the guide rail. When the top of the detection slide 12 enters the driving straight portion 112 from the return inclined portion 111, the detection push rod 13 is restricted by the driving straight portion 112 and cannot move upward, and ultimately the detection push rod 13 is always forced to be inserted between the spacing of the driving teeth 10. Under the premise that 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 limits the rotation of the wire pressing belt 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 is used to pull the wire pressing belt 9 to rotate counterclockwise. At this time, the movement directions of the two wire pressing belts 9 are the same, and the movement direction of the lower wire pressing belt 9 is opposite to that of the cable 2, that is, Figure 9Since the cable 2 contacts the lower crimping tape 9 only by the protrusion, when the crimping tape 9 and the cable 2 move relative to each other, the rough surface of the outer side of the crimping tape 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 delivered to the wrapping assembly 3 will not have protrusion defects, and ultimately ensuring the wrapping quality.

[0031] When the detection slide 12 moves to the right, the detection push rod 13 moves to the detection bevel 113. On the one hand, the detection push rod 13 is further pushed toward the wire pressing belt 9, keeping the wire pressing belt 9 in a tensioned state. On the other hand, the detection push rod 13 is restricted by the wire pressing belt 9 and cannot pass the detection bevel 113, thereby limiting the detection push rod 13 from continuing to move toward the electromagnet assembly 15, that is, 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 moved to the right still restricts the movement of the wire pressing belt 9. This ensures that when the protrusion on the cable 2 and the stationary wire pressing belt 9 move relative to each other, the protrusion manufacturing defects can still be ground away.

[0032] At the same time, from Figure 5 and Figure 6 It can be seen that the side of the adjustment slider 6 is fixedly mounted with a stop switch 14 located below the bottom of the detection bevel 113. When the stop switch 14 is pressed, it can send an electrical signal to the control system, and stop the work and alarm. The reason is that when the wire pressing belt 9 is used for a long time, the tightness will be relatively reduced. Under normal conditions, when the detection slide 12 is moved to the right by the magnetic force between the permanent magnet 121 and the electromagnet assembly 15, the detection push rod 13 will hit the inclined surface of the detection bevel 113. The wire pressing belt 9 with normal tension will limit the movement of the detection push rod 13 along the detection bevel 113, forcing the detection slide 12 not to contact the stop switch 14. When the tightness of the wire pressing belt 9 decreases after long-term use, it is pushed by the detection push rod 13 to continue to push the wire pressing belt 9 downward, causing the length of the detection push rod 13 to extend downward further, and the distance the detection push rod 13 travels to the right along the detection inclined portion 113 is also relatively increased, eventually causing the detection slide 12 to reach the stop switch 14. After the stop switch 14 sends a signal to the control system, it can stop wrapping and alarm, thereby warning the operator that the wire pressing belt 9 needs to be replaced. By using this detection method, it is possible to detect whether the wire pressing belt 9 is in normal use, greatly ensuring that the wire pressing belt 9 mentioned in this application has a clamping and anti-rotation effect on the cable 2.
