Description

Technical Field

[0001] The present invention relates to the technical field of armoring machines, and in particular to a cable copper tape armoring machine. Background Art

[0002] In the current field of cable production, the copper tape armoring process is crucial. Cables may be subjected to various external forces during production, transportation and installation, causing them to bend to a certain extent. This bending not only affects the appearance of the cable, but also affects the winding of the copper tape during the armoring process. Copper tapes may also bend during production and handling due to improper storage, external forces during handling, and other reasons. Bent copper tapes tend to deviate from the intended path when winding, resulting in uneven winding. The surface of the cable and copper tape may be uneven, which may be caused by defects in the manufacturing process, wear or other external factors. The uneven surface will cause the copper tape to not fit tightly when winding, resulting in looseness.

[0003] When there is a bend in the cable or copper tape, the copper tape is prone to deviate from the predetermined winding path during the winding process, resulting in uneven winding. This deflection not only affects the appearance of the armor layer, but may also reduce its mechanical protection performance. During the winding process of cables or copper tapes with uneven surfaces, the copper tape is difficult to fit tightly and is prone to gaps and looseness. Loose copper tapes cannot provide sufficient mechanical protection and may cause the armor layer to fail during use. Bent and uneven cables or copper tapes make it impossible for the copper tape to form a tight spiral structure when winding, resulting in the armor layer being not tight enough. This not only affects the mechanical strength of the armor layer, but may also affect its shielding effect. Summary of the invention

[0031] The working principle and beneficial effects of the present invention are:

[0032] In the present invention, the core wire enters the first channel through the bare wire inlet. At the same time, as the core wire moves, the first layer of copper tape is wound around the core wire through the first tape inlet. The wound armored wire moves out of the first sleeve through the armor wire outlet. Because the first layer of copper tape always passes through the first tape inlet, the first sleeve will maintain a fixed horizontal position and will rotate along with the winding process of the first layer of copper tape when the winding position and winding angle of the first layer of copper tape remain unchanged.

[0033] The first pressing roller is rotatably arranged on the first sleeve. After the first layer of copper tape passes through the gap and is wound on the core wire, the first pressing roller will follow the movement (revolve around the core wire) as the first sleeve rotates. During the movement, the first layer of copper tape in the part just wound is rolled. The following pressing can ensure that the first layer of copper tape fits tightly with the core wire to avoid gaps or looseness. This makes the armor layer more uniform and firm, and improves the overall quality of the armor. Good fit can effectively prevent external factors (such as moisture, dust, etc.) from invading the inside of the armor, and enhance the protection of armored objects such as internal cables or pipes. The copper tape may be wrinkled or overlapped during the winding process, affecting the appearance and performance of the armor. The timely pressing of the first pressing roller can effectively reduce the occurrence of these problems. The pressure applied by the pressing roller makes the copper tape wrap smoothly on the armored object, ensuring the smoothness and continuity of the armor layer. The uniformly pressed armor layer can make the entire structure more stable and reduce deformation or distortion caused by loose or uneven distribution of the copper tape. The timely pressing of the first pressing roller can timely correct the position and state of the copper strip during the winding process, reduce the rework and adjustment time after quality problems occur, and because the rotation of the first pressing roller is driven by the rotation of the first layer of copper strip itself, it can adapt to the production speed of the armoring machine at any time, ensuring that good pressing effects can be achieved at different production speeds.

DETAILED DESCRIPTION

[0042] In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the specific implementation methods of the present invention will be described below with reference to the accompanying drawings.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0045] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0046] Reference Figure 1 to Figure 6A cable copper tape armoring machine is proposed, which is used to wind a copper tape 1 on a moving core wire 2 to form an armored wire 3. Taking the winding of a double-layer copper tape 1 on the core wire 2 as an example, the core wire 2 refers to a cable bundle formed by twisting a single or multiple conductive wire cores or multiple insulated wire cores after insulation treatment. The first layer of copper tape 1-1 and the second layer of copper tape 1-2 are both wound in an interval and inclined manner. The second layer of copper tape 1-2 is unwound on the first layer of copper tape 1-1 and covers the winding gap of the first layer of copper tape 1-1. For details, refer to Figure 4 , including: a first sleeve 4, the first sleeve 4 has a first channel 5, the two ends of the first channel 5 are respectively a bare wire inlet 501 and an armor wire outlet 502, the core wire 2 enters the first channel 5 through the bare wire inlet 501, and the armor wire 3 moves out of the first channel 5 through the armor wire outlet 502, the first sleeve 4 also has a first belt inlet 503, the copper belt 1 enters the first channel 5 through the first belt inlet 503. A first pressing roller 6, the first pressing roller 6 is rotatably arranged on the first sleeve 4, and rolls against the surface of the armor wire 3; a second pressing roller 7, the second pressing roller 7 has two, both of which are rotatably arranged in the first belt inlet 503, and rolls against the surface of the armor wire 3, and a passing gap 701 is formed between the two pressing rollers, and the passing gap 701 is used to pass the copper belt 1.

[0047] In this embodiment, the core wire 2 enters the first channel 5 through the bare wire inlet 501. At the same time, as the core wire 2 moves, the first layer of copper tape 1-1 is wound around the core wire 2 through the first tape inlet 503, and the wound armored wire 3 moves out of the first sleeve 4 through the armor wire outlet 502. Because the first layer of copper tape 1-1 always passes through the first tape inlet 503, the first sleeve 4 will maintain a fixed horizontal position when the winding position and winding angle of the first layer of copper tape 1-1 remain unchanged, and will rotate along with the winding process of the first layer of copper tape 1-1.

[0048] The first pressing roller 6 is rotatably arranged on the first sleeve 4. After the first layer of copper tape 1-1 passes through the gap 701 and is wound around the core wire 2, as the first sleeve 4 rotates, the first pressing roller 6 will follow the movement (revolve around the core wire 2), and roll the first layer of copper tape 1-1 just wound in the process of movement. The following pressing can ensure that the first layer of copper tape is closely fitted with the core wire 2 to avoid gaps or looseness. This makes the armor layer more uniform and firm, improves the overall quality of the armor, and good fit can effectively prevent external factors (such as moisture, dust, etc.) from invading the inside of the armor, and enhances the protection of armored objects such as internal cables or pipes. The copper tape may be wrinkled or overlapped during the winding process, affecting the appearance and performance of the armor. The timely pressing of the first pressing roller 6 can effectively reduce the occurrence of these problems. The pressure applied by the pressing roller makes the copper tape smoothly wound around the armored object, ensuring the smoothness and continuity of the armor layer. The uniformly pressed armor layer can make the entire structure more stable and reduce deformation or distortion caused by loose or uneven distribution of the copper tape. The timely pressing of the first pressing roller 6 can timely correct the position and state of the copper strip during the winding process, reduce the rework and adjustment time after quality problems occur, and because the rotation of the first pressing roller 6 is driven by the rotation of the first layer of copper strip 1-1 itself, it can adapt to the production speed of the armoring machine at any time, ensuring that a good pressing effect can be achieved at different production speeds.

[0049] Furthermore, the copper strip 1 includes a first layer of copper strip 1-1 and a second layer of copper strip 1-2, the first layer of copper strip 1-1 is used to pass through the passing gap 701 of the first sleeve 4, the first pressure roller 6 and the second pressure roller 7 in the first sleeve 4 are both used to roll and abut against the first layer of copper strip 1-1, and also includes: a second sleeve 8, the second sleeve 8 is rotatably sleeved on the armored wire 3, located on one side of the first sleeve 4, and its inner diameter is larger than the inner diameter of the first sleeve 4, the second sleeve 8 has a second strip inlet 801, and two second pressure rollers 7 are also rotatably arranged in the second strip inlet 801, and a passing gap 701 is also formed, the second layer of copper strip 1-2 is used to enter through the passing gap 701 of the second sleeve 8, and the second sleeve 8 is also rotatably arranged with the first pressure roller 6, the second pressure roller 7 and the first pressure roller 6 arranged on the second sleeve 8 are both used to roll and abut against the second layer of copper strip 1-2.

[0050] In this embodiment, the second layer of copper strip 1-2 enters the interior of the second sleeve 8 through the gap 701 of the second sleeve 8 and realizes two-layer winding. The first pressure roller 6 and the second pressure roller 7 are synchronously arranged on the second sleeve 8. The working principle is the same as that of the first pressure roller 6 and the second pressure roller 7 on the first sleeve 4, which will not be repeated here.

[0051] Furthermore, the first sleeve 4 and the second sleeve 8 both have a slide groove 9, the length directions of the two slide grooves 9 are parallel to the moving direction of the core wire 2, and also include: a connecting member 10, the two ends of the connecting member 10 are respectively slidably set in the two slide grooves 9.

[0052] In this embodiment, it is considered that during the armoring process, the copper strip 1 as an important armoring material may face the risk of breaking due to various reasons, among which uneven tension and the quality problem of the copper strip 1 itself are two main factors.

[0053] On the one hand, during the operation of the armoring machine, if the tension applied to the copper strip 1 by different parts is inconsistent, the copper strip 1 will be subjected to different stresses in different directions. Local overstretching of the copper strip 1 will reduce the strength of the area. During the continuous armoring operation, if this uneven tension persists or suddenly intensifies at a certain moment, the copper strip 1 is very likely to break at the part where the stress is most concentrated.

[0054] On the other hand, the quality problem of the copper strip 1 itself is also an important reason for the collapse. If there are defects in the copper strip 1 during the production process, such as pores, inclusions and other defects inside, these defects will weaken the overall strength of the copper strip 1. During the armoring process, the copper strip 1 needs to withstand a certain amount of tension, bending force, friction and other forces. The copper strip 1 with quality problems is more likely to break under the action of these forces. In addition, if the material of the copper strip 1 is uneven and the strength of different parts is quite different, the local weak points will first have problems due to uneven force during the armoring process, and eventually cause the copper strip 1 to collapse. Moreover, if the thickness of the copper strip 1 is uneven, the thinner parts will be subjected to greater stress under the same tension, and it is easy to become the starting point of collapse. At the same time, the surface quality of the copper strip 1 is also crucial. If there are scratches, cracks and other damages on the surface, these damaged parts will become stress concentration points, which are more likely to collapse during the armoring process.

[0055] The breakage may occur at the winding point. In traditional equipment, at the moment when the copper strip 1 breaks at the winding point, the part that was originally in a high tension state will quickly release its stored energy. The copper strip 1 that has been wound on the core wire 2 loses its tension support and cannot maintain its original tightness, so it falls off. The design of the first sleeve 4, the second sleeve 8 and the connector 10 can reduce the persistent negative consequences caused by the breakage of the copper strip 1 to a certain extent. Its working principle is as follows:

[0056] 1. When the first layer of copper tape 1-1 is broken and the second layer of copper tape 1-2 is normal:

[0057] ①: The situation of the first layer of copper tape 1-1 is as follows: the copper tape 1 of the first layer of copper tape 1-1 is broken and divided into two parts, one part is wound around the core wire 2, and the other part is not wound around the core wire 2. A part of the first layer of copper tape 1-1 that has been wound around the core wire 2 is left outside the first tape inlet 503. When it is broken, this part of the copper tape 1 releases tension and moves toward the inside of the first sleeve 4. During the movement, it is resisted by the first pressing roller 6, the second pressing roller 7 and the inner wall of the first channel 5, and its speed is slowed down. Only a small part will remain outside the first tape inlet 503 or all enter the channel.

[0058] ②: The situation of the first sleeve 4 is as follows: the first layer of copper belt 1-1 is broken, and the first sleeve 4 loses the horizontal positioning and rotation driving function of the copper belt 1. It is known that the core wire 2 is always moving slowly. The first sleeve 4 is affected by friction under the movement of the core wire 2 and will move with the core wire 2. After the movement, the first sleeve 4 is close to the second sleeve 8. Although the first sleeve 4 loses the rotation driving function of the copper belt 1, the second layer of copper belt 1-2 is wound normally, that is, the second sleeve 8 still keeps rotating, thereby driving the first sleeve 4 to rotate synchronously through the transmission of the connecting piece 10.

[0059] ③: The situation of winding equipment is: when the copper strip breaks, it is usually necessary to stop the machine immediately, that is, stop the movement of core wire 2 and the rotation of related equipment. Since the core wire 2 itself does not move fast, it can be quickly paused, and the related winding equipment usually decelerates during the process of high-speed rotation to temporary stop, that is, it takes 2-3 turns from braking to complete temporary stop (reference value, affected by many factors such as equipment model, size, quality, etc.). However, considering that the second layer of copper tape 1-2 is still in a normal state, it is worth noting that, as a preferred embodiment, the winding of the first layer of copper tape 1-1 can be ahead of the winding of the second layer of copper tape 1-2 by 2-3 turns (the specific number of turns refers to the number of rotations of the relevant winding equipment during the equipment shutdown process), that is, when the first layer of copper tape 1-1 stops winding, the second layer of copper tape 1-2 needs to be recirculated and wound 2-3 turns before it can keep up with the first layer of copper tape 1-1, and will not exceed the first layer of copper tape 1-1. This is done so as not to affect the winding of the second copper tape 1, and it is necessary to synchronously decelerate the core wire 2. Through the deceleration adjustment of the core wire 2 and the relevant winding equipment, the normal winding of the second layer of copper tape 1-2 is guaranteed to avoid the situation where the first layer of copper tape 1-1 has stopped winding after breaking, and the second layer of copper tape 1-2 will be wound 2-3 more times to avoid exceeding the first layer of copper tape 1-1 after winding 2-3 times.

[0060] 2. When the first layer of copper tape 1-1 is wound normally, and the second layer of copper tape 1-2 is wound broken:

[0061] ①: The first layer of copper tape 1-1 is wound normally;

[0062] ②: The first sleeve 4 is in a stable horizontal position;

[0063] ③: The situation of the second sleeve 8 is that the second sleeve 8 has lost the horizontal positioning and rotation driving effect of the copper belt 1, and it is known that the core wire 2 is always moving slowly. The second sleeve 8 is affected by friction under the movement of the core wire 2 and will move with the core wire 2. After moving, it will move away from the first sleeve 4. Although the second sleeve 8 has lost the rotation driving effect of the copper belt 1, the first layer of copper belt 1-1 is wound normally, that is, the first sleeve 4 still keeps rotating, thereby driving the second sleeve 8 to rotate synchronously through the transmission of the connecting piece 10.

[0064] ④: The second copper belt 1-2 is similar to the first copper belt 1-1. It is subject to the resistance of the first roller 6, the second roller 7 and the inner wall of the second sleeve 8, and its speed is slowed down. Only a small part of it will remain outside the second belt inlet 801 or all of it will enter the second sleeve 8.

[0065] 3. When the first layer of copper tape 1-1 and the second layer of copper tape 1-2 are wound and broken synchronously: Different from the above two cases, in this case, it is only necessary to stop the movement of the core wire 2 immediately. The first sleeve 4 and the second sleeve 8 will rotate first under the action of inertia, and slow down under the resistance of the core wire 2 and the copper tape 1, so as to cover the copper tape 1.

[0066] In summary, the first sleeve 4, the second sleeve 8 and the first pressing roller 6 and the second pressing roller 7 arranged on the two sleeves can not only realize follow-up rolling and improve the covering tightness of the copper belt 1, but also can play a protective effect when the copper belt breaks unexpectedly, thereby improving safety and practicality.

[0067] Furthermore, it also includes: a frame 11, the frame 11 is rotatably arranged, and its rotation axis is parallel to the moving direction of the core wire 2; a first guide wheel 12, the first guide wheel 12 is rotatably arranged on the frame 11, a second guide wheel 13, the second guide wheel 13 is rotatably arranged on the frame 11, and is located at the height side of the first guide wheel 12, and the axis of the second guide wheel 13 is parallel to the axis of the first guide wheel 12; a third guide wheel 15, the third guide wheel 15 has two, the two third guide wheels 15 are rotatably arranged, and are located at the height side of the first guide wheel 12 and the second guide wheel 13, the axis of the third guide wheel 15 and the axis of the second guide wheel 13 have an angle, and there is a guide gap 1501 between the two third guide wheels 15, and the copper strip 1 passes through the first guide wheel 12, the second guide wheel 13 and the guide gap 1501 in sequence. The second guide wheel 13 is rotatably and horizontally arranged on the frame 11, and the wheel frame 14 is horizontally arranged on the frame 11.

[0068] In this embodiment, the first guide wheel 12, the second guide wheel 13 and the third guide wheel 15 cooperate with each other to play a guiding role, which is to change the direction of the copper belt 1 on the reel and smoothly wind it on the core wire 2 through the guidance. In order to better play the role of changing the direction and avoid the problem of difficulty in changing the direction caused by too short spacing, the second guide wheel 13 is set on the height side of the first guide wheel 12, that is, when the copper belt 1 moves, it needs to pass through the first guide wheel 12 first, then rise and pass through the second guide wheel 13. The third guide wheel 15 is located on the height side of the first guide wheel 12 and the second guide wheel 13. This design allows a sufficient distance between the second guide wheel 13 and the third guide wheel 15 to adapt to the torsion of the copper belt 1. At the same time, the second guide wheel 13 and the wheel frame 14 can both move in the horizontal direction, so that the winding position can be adjusted, which improves adaptability.

[0069] Furthermore, at least one third guide wheel 15 is rotated and moved along the height direction and arranged on the wheel frame 14, and after moving, it approaches or moves away from another third guide wheel 15, and further includes: an elastic member 16, one end of which is arranged on the third guide wheel 15, and the other end is arranged on the wheel frame 14, and is used to provide elastic force for the third guide wheel 15 to move closer to another third guide wheel 15. It also includes: a ratchet 17, which is arranged at one end of the third guide wheel 15 and has a plurality of ratchet grooves; and a ratchet 18, which is swingably arranged on the wheel frame 14 and is used to engage with one of the ratchet grooves after swinging.

[0070] In this embodiment, it is considered that after the copper belt breaks, a part of it is relieved to a certain extent by the first sleeve 4 and the second sleeve 8, while the other part of the broken copper belt will still follow the swinging of a certain number of circles when the frame 11 rotates at high speed, and this process will undoubtedly produce some safety hazards. In order to reduce this hazard, an elastic member 16 and a ratchet 17 pawl 18 structure are designed. Regarding the elastic member 16, the elastic member 16 can always provide elastic force for the two third guide wheels 15 to approach each other. Its function includes that after the twisted copper belt 1 passes through the guide gap 1501 of the two third guide wheels 15, the two third guide wheels 15 can play a certain flattening role. The effect makes the copper belt 1 wound on the core wire 2 smoother, and cooperates with the ratchet groove of the ratchet 17. Because when the copper belt is transported normally, the two third guide wheels 15 rotate clockwise and counterclockwise respectively, and the copper belt moves toward the core wire 2. However, when it breaks, under the condition of energy release, the copper belt will quickly move in the opposite direction, which will drive the two third guide wheels 15 to change the rotation direction. Through the setting of the ratchet groove of the ratchet 17, when the two third guide wheels 15 rotate in the opposite direction, it can play a clamping role. Combined with the design of the elastic member 16, it can have a certain resistance to the rebound of the copper belt, thereby playing a certain safety precaution effect.
