Description

Technical Field

[0001] This invention specifically relates to a processing equipment for aluminum alloy core fireproof cables, and pertains to the field of cable processing. Background Technology

[0002] Fire-resistant cables are special cables that use rare-earth aluminum alloys as conductors and employ fire-resistant structures such as mica tape, ceramicized materials, or mineral insulation to maintain circuit continuity and ensure line integrity under specified flame temperatures. They are mainly used in scenarios where power must be cut off but the circuit must remain open, such as fire protection and emergency power supply. The processing of fire-resistant cables refers to the entire production process of turning raw materials such as conductors, fire-resistant insulation layers, and flame-retardant sheaths into finished cables that can still conduct electricity in a fire through specialized processes. The core is to complete the formation of the fire-resistant structure.

[0003] A cable wrapping machine with publication number CN106448948A includes a frame, a feeding guide roller, and a take-up guide roller. A vertical cable inlet pipe is mounted on the frame, coaxial with a main shaft. A mounting base is mounted on the main shaft, which is driven to rotate by a motor. Turntables are symmetrically fixed on both sides of the mounting base. A wrapping tape mounting shaft is vertically mounted on each turntable. A lower wrapping tape tray, the wrapping tape itself, and an upper wrapping tape pressure plate are sequentially mounted on the mounting shaft. Two sets of guide tape shafts are mounted on the mounting base. The first set is located outside the cable inlet pipe, and the angle between the first guide tape shaft and the cable inlet pipe is adjustable within the range of 0-180°. The second set is located near the turntable, and the angle between the second guide tape shaft and the cable inlet pipe is adjustable within the range of 0-90°. Each turntable corresponds to one first guide tape shaft and one second guide tape shaft. This invention allows for wrapping tape replacement without cutting the wire core after the wrapping tape is exhausted. Replacement is convenient, does not affect the core wire, and produces high-quality cables.

[0004] In existing equipment, during the process of wrapping flame-retardant material, the strip material is prone to jamming and folding when unwinding, which can cause the strip material to break or the folded position to fail to completely cover the cable core material, affecting the fire-retardant effect. At the same time, the tensile force on the cable core material during the wrapping process can easily cause the cable core to shift. Summary of the Invention

[0005] To address the aforementioned problems, a technical solution is proposed:

[0006] A fire-resistant cable with an aluminum alloy core, comprising:

[0007] An aluminum alloy cable core, wherein a mica tape is fixedly installed on the outer side of the aluminum alloy cable core, an inner sheath is fixedly installed on the outer side of the mica tape, an armor tape is fixedly installed on the outer side of the inner sheath, and an outer sheath is fixedly installed on the outer side of the armor tape.

[0008] Both the outer and inner sheaths are made of low-smoke flame-retardant polyolefin material, and the inner sheath separates the armor belt and the mica belt.

[0009] A processing equipment for aluminum alloy core fireproof cables, comprising:

[0010] The frame has a wire guide mechanism fixedly installed on both sides, which passes through the frame and extends into its interior. A wrapping mechanism is rotatably installed on both sides of the inner wall of the frame. An anti-deviation mechanism is fixedly installed at the center of the interior of the frame, located between the wrapping mechanisms. A motor is fixedly installed on the top of the frame, and a pulley is provided at the output end of the motor. A belt is installed to drive the motor and the wrapping mechanism.

[0011] The winding mechanism includes a turntable, one end of which is rotatably adapted to the inner wall of the frame. A fixed cylinder is fixedly installed on the outer side of the turntable, and a connecting plate is fixedly installed on the outer side of the fixed cylinder away from the turntable. A convex plate is provided on the outer edge of the connecting plate, and a fixed frame is fixedly installed on the outer side of the connecting plate. The fixed frame is located inside the convex plate, and a sliding groove plate is fixedly installed on the inner wall of the fixed frame. There are two sliding groove plates, and each sliding groove plate has a groove on its outer side. Two clamping rollers are slidably installed between the sliding groove plates, and both ends of the clamping rollers are slidably adapted to the grooves of the sliding groove plates. An inner pad ring is provided at each groove of the sliding groove plate. The inner pad ring is made of elastic material. Utilizing the elastic material characteristics of the inner pad ring, during the process of winding and wrapping the aluminum alloy cable core with mica tape, the mica tape material gradually unwinds and passes between the clamping rollers. The pressure of the mica tape material on the clamping rollers is transmitted to the inner pad ring. The inner pad ring utilizes the deformation and compression of the inner pad ring under pressure to change the output direction and buffer the pressure, preventing the mica tape material from momentarily jamming during the winding and wrapping of the cable core. This prevents the increased winding pressure from causing the mica tape material to break due to lack of buffering. A connecting plate is fixedly installed on the inner wall of the fixed frame. The top of the connecting plate has symmetrically arranged protrusions, and a rotating roller is rotatably installed between the protrusions. A gap exists between the rotating roller and the connecting plate. Through the cooperation of the rotating roller and the convex plate, the bottom of the rotating roller contacts the mica tape material as it is wound around the cable core surface. During output, it tightly adheres to the convex strip of the convex plate, preventing the mica tape material from shifting and folding. Folded areas would not completely cover the cable core material after winding and wrapping, leading to exposure of the cable core material and affecting fire resistance. A convex plate is fixedly installed on the top of the connecting plate away from the clamping roller, and the top of the convex plate has oblique protrusions.

[0012] Preferably, a pulley is fixedly installed on the outer side of the turntable, the pulley is located on the outer side of the fixed cylinder, a screw-hole rod is fixedly installed on the convex plate of the connecting plate, a screw hole is opened at the end of the screw-hole rod away from the convex plate, a sliding plate is slidably installed on the outer side of the screw-hole rod, there are two sliding plates and they are arranged opposite each other, and each sliding plate has an inclined protrusion on its opposite surface, a screw block is threadedly connected to the screw hole of the screw-hole rod, and a pressure rod is fixedly installed on the outer side of the screw block.

[0013] Preferably, the wire guiding mechanism includes a wire guide cylinder. Each end of the wire guide cylinder away from the frame has an inclined groove, and a rectangular groove plate is fixedly installed at the inclined groove. The rectangular groove plates are symmetrically installed along the center of the wire guide cylinder's axis, and rectangular grooves are formed on the outer sides of each rectangular groove plate. An inner sliding plate is slidably installed at each rectangular groove of the rectangular groove plate. A sliding rod is fixedly installed on the outer side of each inner sliding plate. A perforated plate is fixedly installed on the side of the rectangular groove plate closest to the frame. The inner wall of the perforated plate slides smoothly against the outer side of the sliding rod, and a spring is fixedly installed between the perforated plate and the inner sliding plate. A zigzag plate is fixedly installed on the outer side of the inner sliding plate. The bending plate bends towards the center of the conductor tube at one end away from the inner slide plate. An inner clamping post is fixedly installed at the end of the bending plate away from the inner slide plate. The inner clamping post cooperates with the spring. When the cable core is wrapped and pulled, the deviated cable core is transmitted to the inner slide plate through the inner clamping post and the bending plate. This causes the inner slide plate to compress the spring and deform, thus buffering the deviation pressure. At the same time, the arc groove of the inner clamping post contacts the cable core material and guides it, limiting the deviation angle of the cable core and preventing the deviation angle from being too large, which would cause the cable core to bend and affect the coverage of the mica tape material. Arc grooves are opened at the center of the opposite surfaces of the inner clamping post.

[0014] Preferably, the anti-deviation mechanism includes a support frame, with a support sleeve fixedly installed on the outer side of the support frame. The support sleeves are symmetrically installed along the center of the axis of the support frame, and a support cylinder is fixedly installed on the inner wall of each support sleeve. A grooved cylinder is fixedly installed at each non-opposite end of the support cylinder. The inner diameter of the grooved cylinder gradually increases as it moves away from the support cylinder, and a groove is formed on the inner wall of the grooved cylinder. An inner support ring is fixedly installed at each groove of the grooved cylinder. The inner support ring is made of elastic material, and an inner sliding ring is slidably installed at the groove of the grooved cylinder. The inner wall of each inner slip ring is fixedly equipped with an arc-shaped protruding ring. The arc surface of the arc-shaped protruding ring cooperates with the inner support ring. The arc surface of the arc-shaped protruding ring contacts the surface of the cable core initially covered with mica tape, reducing the contact area with the surface mica tape, reducing friction, and preventing scratches and damage to the mica tape during passage. At the same time, the elastic deformation characteristics of the inner support ring are used to limit and buffer the pulling force when the wrapping mechanism at both ends is wrapped and pulled. It also separates the wrapping mechanism to avoid mutual interference when the two sides are wrapped and pulled. The inner wall of the arc-shaped protruding ring is a raised arc surface.

[0015] This invention provides a processing equipment for aluminum alloy core fireproof cables, which has the following beneficial effects:

[0016] (i) By using the combination of the rotating roller and the convex plate, the mica tape material is wound around the surface of the cable core. The bottom of the rotating roller contacts the mica tape material and closely fits the convex strip of the convex plate when it is discharged. This prevents the mica tape material from shifting and from folding. Otherwise, after the winding and covering, the folded position cannot completely cover the cable core material, resulting in the exposure of the cable core material and affecting fire resistance and flame retardancy.

[0017] (ii) Utilizing the elastic material characteristics of the inner pad ring, during the process of winding and wrapping the aluminum alloy cable core with mica tape, the mica tape material is gradually unwound and passes between the clamping rollers. The pressure of the mica tape material on the clamping rollers is transmitted to the inner pad ring. The inner pad ring is deformed and compressed under pressure to change the output direction and buffer the pressure. This avoids the mica tape material from being stuck briefly during the winding and wrapping of the cable core, which would increase the winding pressure and cause the mica tape material to break.

[0018] (III) When the cable core is wrapped and pulled by the inner clamping post and spring, the cable core is deviated by the inner clamping post and the bending plate. The deviated cable core is transmitted to the inner sliding plate through the inner clamping post and the bending plate. The inner sliding plate compresses the spring and deforms to buffer the deviated pressure. At the same time, the arc groove of the inner clamping post contacts the cable core material and guides it to limit the deviated angle of the cable core. This prevents the deviated angle from being too large, which would cause the cable core to bend and affect the covering of the mica tape material.

[0019] (iv) By cooperating with the inner support ring through the arc surface of the arc convex ring, the arc surface of the arc convex ring contacts the surface of the cable core initially covered with mica tape, reducing the contact area with the surface mica tape, reducing friction, and preventing scratches and damage to the mica tape during the passing process. At the same time, by utilizing the elastic deformation characteristics of the inner support ring, the pulling force is limited and buffered when the wrapping mechanism at both ends is wrapped and pulled. At the same time, it separates the wrapping mechanisms to avoid mutual interference when the two sides are wrapped and pulled. Attached Figure Description

[0031] Example 1, Reference Figures 1 to 6 The present invention provides the following technical solution:

[0032] A fire-resistant cable with an aluminum alloy core, comprising:

[0033] An aluminum alloy cable core 1 is fixedly installed on the outside of the aluminum alloy cable core 1. An inner sheath 4 is fixedly installed on the outside of the mica tape 5. An armor tape 3 is fixedly installed on the outside of the inner sheath 4. An outer sheath 2 is fixedly installed on the outside of the armor tape 3.

[0034] Both the outer sheath 2 and the inner sheath 4 are made of low-smoke flame-retardant polyolefin material. The inner sheath 4 separates the armor belt 3 and the mica belt 5.

[0035] A processing equipment for aluminum alloy core fireproof cables, comprising:

[0036] The frame 6 has a wire guide mechanism 7 fixedly installed on both sides. The wire guide mechanism 7 passes through the frame 6 and extends into its interior. The inner walls of the frame 6 are rotatably installed on both sides. The center of the interior of the frame 6 is fixedly installed with an anti-deviation mechanism 8, which is located between the wire guide mechanisms 9. The top of the frame 6 is fixedly installed with a motor 10. The output end of the motor 10 is provided with a pulley. A belt 11 is installed between the motor 10 and the wire guide mechanism 9 for transmission.

[0037] The winding mechanism 9 includes a turntable 907, one end of which is rotatably adapted to the inner wall of the frame 6. A fixing cylinder 909 is fixedly installed on the outer side of the turntable 907. A connecting plate 901 is fixedly installed on the outer side of the fixing cylinder 909 away from the turntable 907. A convex plate is provided at the outer edge of the connecting plate 901. A fixing frame 902 is fixedly installed on the outer side of the connecting plate 901, located inside the convex plate. A sliding plate 910 is fixedly installed on the inner wall of the fixing frame 902. There are two sliding plates 910, and each sliding plate 910 has a groove on its outer side. A clamping roller 912 is slidably installed between the sliding plates 910. Before the cable is inserted, the mica tape reel is placed outside the screw hole rod 903 and positioned between the sliding plates 904. Then, the screw block 905 is threaded into the screw hole rod 903. During the tightening process, the pressure rod 906 is driven to contact the outermost part of the screw hole rod. The sliding discs 904 clamp the mica tape reel between them. After the cable core is inserted, one end of the mica tape reel is inserted into the fixed frame 902, so that the mica tape 5 first passes through the clamping rollers 912, then passes through the gap between the connecting plate 914 and the rotating roller 915, and finally exits close to the convex strip of the convex strip plate 913. There are two clamping rollers 912, and the two ends of the clamping rollers 912 are slidably adapted to the groove of the sliding groove plate 910. An inner pad ring 911 is provided at each of the 0 slide grooves. The inner pad ring 911 is made of elastic material. A connecting plate 914 is fixedly installed on the inner wall of the fixed frame 902. The top of the connecting plate 914 is symmetrically provided with protrusions. A rotating roller 915 is rotatably installed between the protrusions. There is a gap between the rotating roller 915 and the connecting plate 914. A raised strip plate 913 is fixedly installed on the side of the top of the connecting plate 914 away from the clamping roller 912. The top of the raised strip plate 913 is provided with an oblique raised strip.

[0038] A pulley 908 is fixedly installed on the outer side of the turntable 907. The pulley 908 is located on the outer side of the fixed cylinder 909. A screw rod 903 is fixedly installed on the convex plate of the connecting plate 901. A screw hole is opened at the end of the screw rod 903 away from the convex plate. A sliding plate 904 is slidably installed on the outer side of the screw rod 903. There are two sliding plates 904, which are arranged opposite to each other. During the winding and wrapping process, the mica tape roll is fixed to the cable core by winding one end. The motor 10 is connected to the pulley 908 through the belt 11, which drives the turntable 907 to rotate, causing the connecting plate 901 to rotate. The mica tape roll continuously wraps the cable core material that passes through. When it passes through the winding mechanism 9 on the other side, the mica tape roll material is wrapped again. The opposite surfaces of the sliding plates 904 are provided with inclined protrusions. A screw block 905 is threadedly connected to the screw hole of the screw rod 903. A pressure rod 906 is fixedly installed on the outer side of the screw block 905.

[0039] Example 2, based on Example 1, with reference to Figures 7 to 8 The conductor mechanism 7 includes a conductor drum 71. Each end of the conductor drum 71 away from the frame 6 has an inclined groove, and a rectangular groove plate 73 is fixedly installed at the inclined groove of the conductor drum 71. The rectangular groove plates 73 are symmetrically installed along the center of the conductor drum 71's axis, and rectangular grooves are formed on the outer sides of each rectangular groove plate 73. An inner sliding plate 76 is slidably installed at each rectangular groove of the rectangular groove plate 73, and a sliding rod 77 is fixedly installed on the outer side of each inner sliding plate 76. A perforated plate 75 is fixedly installed on the side of the rectangular groove plate 73 closest to the frame 6. The aluminum alloy cable core 1 enters through the inclined groove of one side of the conductor drum 71 and, under the traction of the winding device, exits through the inclined groove of the other side of the conductor drum 71. When the cable core passes through the inclined groove of the conductor drum 71, it contacts both sides of the cable core through the arc-shaped grooves on the opposite sides of the inner clamping post 74. The inner slide plate 76 is supported by spring 78, so that the inner clamping post 74 is in close contact with the surface of the cable core. The inner wall of the perforated plate 75 is adapted to slide with the outer side of the slide rod 77. A spring 78 is fixedly installed between the perforated plate 75 and the inner slide plate 76. A zigzag plate 72 is fixedly installed on the outer side of the inner slide plate 76. The end of the zigzag plate 72 away from the inner slide plate 76 bends towards the center of the conductor tube 71. When the cable core is covered with mica tape 5 and there is a deviation and swing, the force is transmitted to the inner slide plate 76 through the inner clamping post 74 and the zigzag plate 72, so that the inner slide plate 76 transmits the pressure to the spring 78, compresses the deformation of the spring 78, limits the deviation of the cable core, and buffers the force. The inner clamping post 74 is fixedly installed on the end of the zigzag plate 72 away from the inner slide plate 76. An arc groove is opened at the center of the opposite surface of the inner clamping post 74.

[0040] Example 3, based on Examples 1 and 2, with reference to Figures 9 to 10The anti-deviation mechanism 8 includes a support frame 81. A support sleeve 82 is fixedly installed on the outer side of the support frame 81. The support sleeves 82 are symmetrically installed along the center position of the axis of the support frame 81, and a support cylinder 83 is fixedly installed on the inner wall of each support sleeve 82. A grooved cylinder 84 is fixedly installed on each non-opposite end of the support cylinder 83. The inner diameter of the grooved cylinder 84 gradually increases as it moves away from the support cylinder 83, and a groove is formed on the inner wall of the grooved cylinder 84. An inner support ring 85 is fixedly installed at each groove of the grooved cylinder 84. The cable core, after being wrapped with a layer of mica, is inserted into the grooved cylinder 84 at one end, and the cable core is then guided by an arc-shaped protrusion ring 87. The cable core passes through the interior of the cable core, and the convex arc surface inside the arc ring 87 contacts the mica roll material covering the surface of the cable core. When the cable core material is wrapped, the tension generated on the cable core causes the cable core to deflect, and the force is transmitted to the inner support ring 85 through the arc ring 87 and the inner slip ring 86. This causes the inner support ring 85 to compress and deform under pressure, and causes the inner slip ring 86 to slide and deflect at the annular groove position of the annular groove cylinder 84. The inner support ring 85 is made of elastic material, and the inner slip ring 86 is slidably installed at the annular groove of the annular groove cylinder 84. The inner wall of the inner slip ring 86 is fixedly installed with the arc ring 87, and the inner wall of the arc ring 87 is a convex arc surface.

[0041] In use, the roll of mica tape 5 to be wrapped around the surface of the cable core is loaded into the winding mechanism 9. Then, the aluminum alloy cable core 1 is passed through the conductor mechanism 7 on one side and through the winding mechanism 9, then through the anti-deviation mechanism 8 and the winding mechanism 9 on the other side, and finally out through the conductor mechanism 7 on the other side. It is then wound up by the winding device. At the same time, the aluminum alloy cable core 1 is driven by the winding device to pass through the device. During the passage, as the cable core passes through, the mica tape loaded into the winding mechanism 9 is rotated by the motor 10 through the belt 11, which wraps the mica tape 5 around the surface of the aluminum alloy cable core 1.

[0042] In the conductor mechanism 7, the aluminum alloy cable core 1 is inserted through the inclined groove of the conductor drum 71 on one side and, driven and pulled by the winding equipment, exits through the inclined groove of the conductor drum 71 on the other side. When the cable core passes through the inclined groove of the conductor drum 71, it contacts both sides of the cable core through the arc groove of the inner clamping post 74. The inner sliding plate 76 is supported by the spring 78, so that the inner clamping post 74 is in close contact with the surface of the cable core. At the same time, when the cable core is covered with mica tape 5 and there is a deviation and swing, the force is transmitted to the inner sliding plate 76 through the inner clamping post 74 and the bending plate 72, so that the inner sliding plate 76 transmits the pressure to the spring 78, compresses the deformation of the spring 78, limits the deviation of the cable core, and buffers the force.

[0043] In the winding mechanism 9, before the cable is inserted, the mica tape reel is placed outside the screw hole rod 903 and positioned between the slide plates 904. Then, the screw block 905 is threaded into the screw hole rod 903. During tightening, the pressure rod 906 contacts the outermost slide plate 904, clamping the mica tape reel between the slide plates 904. After the cable core is inserted, one end of the mica tape reel is inserted into the fixed frame 902, allowing the mica tape 5 to pass through the clamping rollers 912 first. It then passes through the gap between the connecting plate 914 and the rotating roller 915, and finally exits close to the convex strip of the convex strip plate 913. During the winding and wrapping process, one end of the mica tape roll is fixed to the cable core by winding. The motor 10 is connected to the pulley 908 through the belt 11, which drives the turntable 907 to rotate, causing the connecting plate 901 to rotate. This causes the mica tape roll to continuously wrap the cable core material that passes through. When it passes through the winding mechanism 9 on the other side, the mica tape roll material is wrapped again.

[0044] In the anti-deviation mechanism 8, the cable core, after being wrapped with a layer of mica roll, is inserted into the annular groove cylinder 84 at one end and passes through the inside of the arc-shaped protrusion ring 87. The convex arc surface inside the arc-shaped protrusion ring 87 contacts the mica roll material covering the surface of the cable core. When the cable core material is wrapped, the tension generated on the cable core causes the cable core to deviate. The force is transmitted to the inner support ring 85 through the arc-shaped protrusion ring 87 and the inner slip ring 86, causing the inner support ring 85 to be compressed and deformed under pressure, and causing the inner slip ring 86 to slide and deviate at the annular groove position of the annular groove cylinder 84.
