Description

Technical Field

[0001] The invention relates to the technical field of wire and cable manufacturing, in particular to a device and a method for automatically winding aluminum foil around a cable surface online. Background Art

[0002] The main uses of cable aluminum foil include as a shielding layer for cables to protect the internal signals of the cables from external interference and ensure the stability and reliability of signal transmission. Cable aluminum foil is also widely used in the communication, power transmission, medical, automotive and other industries. For example, in the communication industry, it is used to shield electromagnetic wave interference and protect signal transmission; in the power system, it is used to reduce electromagnetic radiation and interference to ensure the normal operation of the power system; in the medical industry, it is used to prevent the influence of electromagnetic interference on the operation of equipment; in the automotive industry, it is used to provide good electromagnetic compatibility to ensure the normal operation of electronic equipment in the car. In addition, cable aluminum foil is also used in the packaging of food, medicine, cosmetics, etc., as well as thermal insulation materials for buildings, vehicles, ships, etc.

[0003] The existing aluminum foil winding equipment on the market is technically traditional and backward. For example, when the aluminum foil gets stuck or breaks, the aluminum foil winding on the cable surface will be interrupted, which will cause some areas of the cable to be not covered with aluminum foil, and the expected shielding effect or other specific functional requirements cannot be achieved. Traditional equipment cannot detect whether aluminum foil of different specifications is broken, and there is a lack of equipment specifically for detecting aluminum foil breakage on the market. Secondly, when the aluminum foil breaks, if the transmission system of the equipment does not respond quickly to stop running, the pay-off roller will continue to rotate, which will cause excessive release of aluminum foil, making the aluminum foil loose and unevenly wound, affecting subsequent use and processing, reducing production continuity and efficiency, and increasing downtime and production losses caused by aluminum foil breakage.

[0004] Therefore, it is necessary to propose a device and method for automatically winding aluminum foil around the cable surface online to solve the above technical problems. Summary of the invention

DETAILED DESCRIPTION The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] See also Figures 1 to 5 The present invention provides a technical solution: an equipment for automatically winding aluminum foil on the surface of a cable online, comprising an aluminum foil winding frame 1, at least one pay-off roller 11 is arranged on the aluminum foil winding frame 1, an upper roller 12 is arranged on one side of the aluminum foil winding frame 1, and a lower roller 13 is arranged on the other side of the aluminum foil winding frame 1, and an alarm is installed on the aluminum foil winding frame 1. The pay-off roller 11, the upper roller 12 and the lower roller 13 work together to realize the automatic winding of aluminum foil on the surface of the cable. The pay-off roller 11 provides a source of aluminum foil, and a plurality of rollers can be set according to actual needs to meet different aluminum foil usage. The upper roller 12 and the lower roller 13 are respectively located on the upper and lower sides of the aluminum foil winding frame 1 to guide the movement direction of the aluminum foil to ensure that the aluminum foil is accurately and evenly wound on the cable surface. At the same time, the alarm installed on the aluminum foil winding frame 1 adds safety protection and fault prompt functions when detecting aluminum foil breakage.

[0022] The rupture detection component 2 is arranged on the aluminum foil winding frame 1 and is located between the upper roller 12 and the lower roller 13, and is used to detect whether the aluminum foils of different specifications are broken. The rupture detection component 2 includes a pair of detection frames 21 installed on the left side of the aluminum foil winding frame 1. The opposite sides of the pair of detection frames 21 are both installed with transverse blocks 22. The two transverse blocks 22 are connected with a fixed block 23 that moves along the front and rear directions of the transverse blocks 22 by means of a slide rail. The transverse block 22 is installed with an electric push rod for driving the fixed block 23 to move. The fixed block A fine-tuning block 24 is provided on one side of 23, and the fine-tuning block 24 is in an L-shaped structure. The vertical end of the fine-tuning block 24 is rotatably connected to a detection roller 25, and a rotating block 26 is installed on the top of the detection roller 25. A compression spring 27 is installed at one end of the rotating block 26 away from the detection roller 25, and the end of the compression spring 27 away from the rotating block 26 is installed on the fine-tuning block 24 through a fixed frame. The fine-tuning block 24 is located on one side of the detection roller 25 and is installed with an angle sensor 14 for detecting the rotation angle of the detection roller 25 to determine the tension information of the aluminum foil.

[0023] It should be noted that: the fixed block 23 is pushed by the electric push rod to move along the transverse block 22 in the direction close to the pay-off roller 11, and the movement of the fixed block 23 drives the fine-tuning block 24, the detection roller 25 and other components to move together to ensure that the detection roller 25 is in the best detection position. When the aluminum foil runs in the equipment and passes through the detection roller 25, the tension of the aluminum foil will squeeze the detection roller 25. If the tension of the aluminum foil is normal, under the action of the compression spring 27, the detection roller 25 will remain in a relatively stable position. At this time, the rotating block 26 is also at a specific angle. As the aluminum foil continues to run, if the tension of the aluminum foil When the tension changes, the detection roller 25 will be pushed to move. When the tension increases, the detection roller 25 moves forward, the rotating block 26 rotates accordingly, and the compression spring 27 is stretched. When the tension suddenly decreases or disappears, the compression spring 27 will drive the detection roller 25 to move backward, which means that the aluminum foil is broken. The angle sensor 14 is installed on the fine-tuning block 24 to detect the change in the rotation angle of the detection roller 25 in real time. By analyzing the change in angle, the tension information of the aluminum foil can be accurately judged. When the aluminum foil is broken, the signal can be transmitted through the angle sensor 14 and the external terminal, and the alarm will be prompted.

[0024] like Figure 3 and Figure 4As shown, a pointer 211 is installed on the right side of the detection roller 25, a dial 212 is installed on the side of the vertical end of the fine-tuning block 24 away from the detection roller 25, a sleeve 213 is arranged on the fixed block 23, a slot is opened in the sleeve 213, the fine-tuning block 24 is slidably connected inside the slot, an expansion spring 214 fixedly connected to the horizontal end of the fine-tuning block 24 is installed in the slot, one end of the sleeve 213 away from the fine-tuning block 24 is threadedly connected to the first torsion rod 215, and one end of the first torsion rod 215 is rotatably connected to the horizontal end of the sleeve 213.

[0025] It should be noted that: when the first torsion rod 215 is rotated, due to the action of the thread, the first torsion rod 215 will move axially in the sleeve 213, so that the first torsion rod 215 can push the fine-tuning block 24 during the rotation process. When the first torsion rod 215 pushes the fine-tuning block 24, the fine-tuning block 24 will move telescopically along the slot. The spring potential energy of the expansion spring 214 can prompt the fine-tuning block 24 to drive the detection roller 25 to always maintain contact with the aluminum foil and move stably along the aluminum foil. The operator can accurately understand the moving distance of the fine-tuning block 24 by observing the position of the pointer 211 on the dial 212, thereby more accurately adjusting the contact position and pressure of the detection roller 25 with the aluminum foil. The first torsion rod 215 can be adjusted according to aluminum foils of different specifications to achieve the extension and retraction of the fine-tuning block 24, thereby adjusting the contact position and pressure of the detection roller 25 with the aluminum foil.

[0026] like Figure 2 and Figure 3 As shown, a first guide roller 15 is installed at the top front end of the detection frame 21, and a second guide roller 16 and a third guide roller 17 are respectively installed at the middle and bottom of the detection frame 21 and at one end away from the first guide roller 15. The detection roller 25 is located in the middle of the second guide roller 16 and the third guide roller 17, and the detection roller 25 contacts the aluminum foil in a horizontal direction.

[0027] It should be noted that: the first guide roller 15 is located at the top front end of the detection frame 21, and its main function is to receive the aluminum foil transmitted by the upper roller 12 and guide it to the second guide roller 16 and the third guide roller 17. The position design of the second guide roller 16 and the third guide roller 17 enables the aluminum foil to maintain a certain tension and vertical state during the transmission process to avoid the aluminum foil from being loose or twisted. At the same time, the detection roller 25 contacts the vertical aluminum foil in a horizontal manner, so that the detection roller 25 can be evenly stressed on the aluminum foil, which better reflects the tension of the aluminum foil. If the detection roller 25 contacts the aluminum foil at an inclined or other angle, it may cause uneven stress and affect the accuracy of the detection result.

[0028] like Figure 4 and Figure 5As shown, a connecting plate 2211 is installed at the bottom of the rear end of the sleeve 213, and a bullet-proof seat 221 is installed at the end of the connecting plate 2211 away from the sleeve 213. A slope 222 is provided on the side of the bullet-proof seat 221 close to the detection roller 25. The slope 222 is used to drive the aluminum foil to be clamped and fixed on the slope 222 when the detection roller 25 detects that the aluminum foil is broken.

[0029] It should be noted that when the aluminum foil breaks, the detection roller 25 will change its angle position due to the loss of the tension of the aluminum foil. During this process, the detection roller 25 will move toward the bulletproof seat 221. Since the bulletproof seat 221 is provided with an inclined surface 222 on one side close to the detection roller 25, the detection roller 25 will move with the broken aluminum foil and clamp the aluminum foil on the inclined surface 222. The design of the inclined surface 222 makes it easier to fix the aluminum foil on the bulletproof seat 221, and the aluminum foil clamped on the inclined surface 222 will not float around at will, reducing the safety risk to the operator and avoiding the dangerous situations such as entanglement and scratches caused by the broken aluminum foil. It is worth noting that the bulletproof seat 221 is slidably connected to the vertical end of the fine-tuning block 24, which is conducive to the sliding of the bulletproof seat 221 to provide a certain limit effect on the aluminum foil during the extension and retraction process of the fine-tuning block 24.

[0030] like Figure 2-Figure 5 As shown, a limiting hole 231 is provided through the middle of the fixed block 23, and the sleeve 213 slides horizontally on the fixed block 23 by means of a slide rail connection. A moving block 232 is installed at one end of the sleeve 213 away from the fine-tuning block 24. The moving block 232 has an F-shaped structure, and the horizontal end below the moving block 232 is slidably connected to the inner side of the limiting hole 231 and is threadedly connected to the first torsion rod 215. The upper horizontal end of the moving block 232 is threadedly connected to the second torsion rod 233. The moving block 232 can be fixed and loosened by loosening the second torsion rod 233 on the fixed block 23. The positions of the front and rear ends of the limiting hole 231 correspond to the middle positions of the front and rear pay-off rollers 11.

[0031] It should be noted that: when the aluminum foil breaks, in order not to interrupt production, the aluminum foil on another pay-off roller 11 can be used to continue operation. First, loosen the second torsion rod 233 to release the fixation of the moving block 232. Since the moving block 232 is an F-shaped structure, its lower horizontal end is slidably connected to the inner side of the limiting hole 231. After loosening the second torsion rod 233, the moving block 232 can be moved on the fixed block 23 by pushing it. The positions of the front and rear ends of the limiting hole 231 correspond to the middle positions of the front and rear pay-off rollers 11, which means that during the movement, the moving block 232 can be quickly and accurately moved to the middle position of another pay-off roller 11 through the limitation of the limiting hole 231. After moving to the middle position of the new pay-off roller 11, the aluminum foil can smoothly pass through the detection roller 25 to restore the tension detection of the aluminum foil. Finally, tighten the second torsion rod 233 to fix the moving block 232 so that the equipment continues to operate stably; By setting the limiting hole 231, the moving block 232 and the second torsion rod 233 to cooperate with each other, when the aluminum foil on one pay-off roller 11 breaks, there is no need to completely stop production and carry out tedious processing. The aluminum foil on the other pay-off roller 11 can be quickly switched to continue running, which greatly improves the continuity and efficiency of production and reduces the downtime and production loss caused by the breakage of the aluminum foil.

[0032] like Figure 2 and Figure 3 As shown, a limiting frame 241 is installed on the opposite sides of a pair of detection frames 21, a limiting plate 242 is installed at one end of the limiting frame 241 away from the detection frame 21, and a triangular plate 243 is installed at one end of the bulletproof seat 221 away from the detection roller 25. The limiting plate 242 is a right triangle, and the side surfaces of the limiting plate 242 are tightly attached to the side surfaces of the triangular plate 243.

[0033] It should be noted that: the present invention can cooperate with the triangular plate 243 and the limiting plate 242 in the form of an isosceles right triangle, so that when the detection roller 25 is at different positions of the pay-off roller 11, the triangular plate 243 contacts the limiting plates 242 on both sides and can provide corresponding reaction forces, thereby further enhancing the reliability of the limiting of the detection roller 25.

[0034] like Figure 2 , Figure 6 and Figure 7As shown, the quick stop roller assembly 3 is arranged on one side of the pay-off roller 11, and is used to quickly stop the pay-off roller 11 when detecting the aluminum foil rupture to prevent the aluminum foil from being over-released. The quick stop roller assembly 3 includes an arc frame 31 installed at the rear end of the transverse block 22. The arc frame 31 is in a semi-arc shape and is located on the same track as the outer edge of the pay-off roller 11. Telescopic grooves are evenly opened in the arc frame 31, and electromagnetic disks 32 are installed in the telescopic grooves. A reset spring rod 33 that slides through the inner side of the electromagnetic disk 32 is slidably connected to one side of the arc frame 31 corresponding to the telescopic groove, and resets One end of the spring rod 33 extends into the telescopic groove and is installed with a magnetic block column 34 that is tightly attached to the electromagnetic disk 32. One end of the magnetic block column 34 away from the reset spring rod 33 extends out of the outer side of the arc frame 31 and is installed with a clamping disk 35. The detection roller 25, the bulletproof seat 221 and the triangular plate 243 are all made of conductive materials. An insulating wire electrically connected to the limiting plate 242 is installed in the limit frame 241. One end of the insulating wire passes through the fine-tuning block 24 and the arc frame 31 and is electrically connected to the electromagnetic disk 32. When the electromagnetic disk 32 generates a magnetic field, the magnetic block column 34 and the electromagnetic disk 32 repel each other.

[0035] It should be noted that: under normal circumstances where the aluminum foil is not broken, the electromagnetic disk 32 is not energized and does not generate a magnetic field. At this time, the reset spring rod 33 is in a naturally extended state, and the magnetic block column 34 is extended into the inner side of the arc frame 31, so that the clamping disk 35 maintains a certain distance from the outer edge of the pay-off roller 11, and does not affect the normal rotation of the pay-off roller 11; When the detection roller 25 detects that the aluminum foil is broken, the aluminum foil loses tension, and the detection rupture component 2 drives the detection roller 25 to rotate and contact the inclined surface 222 on the bulletproof seat 221. Since the detection roller 25, the bulletproof seat 221 and the triangular plate 243 are all made of conductive materials, and the limit frame 241 is equipped with wires electrically connected to the limit plate 242, the signal is transmitted through these conductive components to the wires electrically connected to the electromagnetic disk 32 in the arc frame 31. The wires transmit the electrical signal to the electromagnetic disk 32, so that the electromagnetic disk 32 is energized, and the electric When the magnetic disk 32 is energized, a magnetic field is generated. Since the material on the magnetic block column 34 and the electromagnetic disk 32 generate a mutual repulsive force, this repulsive force overcomes the elastic force of the reset spring rod 33, and pushes the magnetic block column 34 to move to the outside of the telescopic slot. As the clamping disk 35 approaches the pay-off roller 11, the clamping disk 35 finally fits tightly on the pay-off roller 11, and the friction force produces a braking effect on the pay-off roller 11, so that the pay-off roller 11 is quickly stopped, which can prevent the aluminum foil from continuing to be excessively released after breaking, avoiding causing more confusion and losses.

[0036] like Figure 6 and Figure 7As shown, an arc block 311 is installed on the side of the clamping disk 35 close to the pay-off roller 11, and a rubber pad 314 is installed on the outer edge of the side wall of the pay-off roller 11 close to the arc block 311. The expansion spring 214 is provided with grooves in a ring array, and the grooves are adapted to the arc block 311, and the end of the arc block 311 away from the clamping disk 35 is a pointed structure.

[0037] It should be noted that: when the clamping disk 35 approaches the pay-off roller 11, the arc block 311 first contacts the pay-off roller 11. The existence of the arc block 311 increases the contact area between the clamping disk 35 and the pay-off roller 11, thereby increasing the friction between the two. When the pay-off roller 11 needs to be stopped urgently, the greater friction can more effectively stop the rotation of the pay-off roller 11, ensuring rapid braking. The end of the arc block 311 away from the clamping disk 35 is a pointed structure. The design of the pointed structure can more easily insert into the rubber pad 314 on the surface of the pay-off roller 11 when contacting the pay-off roller 11, thereby further improving the friction and braking efficiency.

[0038] A device method for automatically winding aluminum foil around a cable surface online comprises the following steps: First, ensure that all parts of the equipment are installed intact, and place the aluminum foil roll to be used on the pay-off roller 11; Second, the electric push rod pushes the fixed block 23 to move along the transverse block 22 in the direction close to the pay-off roller 11, driving the fine-tuning block 24, the detection roller 25 and other components to move together to ensure that the detection roller 25 is in the best detection position; Third, the first torsion rod 215 is rotated, and the first torsion rod 215 moves axially in the sleeve 213 to push the fine-tuning block 24, and the fine-tuning block 24 moves telescopically along the notch, and the expansion spring 214 prompts the fine-tuning block 24 to drive the detection roller 25 to always keep in contact with the aluminum foil and move stably along the aluminum foil. The operator can accurately adjust the contact position and pressure between the detection roller 25 and the aluminum foil by observing the position of the pointer 211 on the dial 212 to adapt to aluminum foils of different specifications; Fourth, as the aluminum foil keeps running, if the tension changes, it will push the detection roller 25 to move. When the tension increases, the detection roller 25 moves forward, the rotating block 26 rotates accordingly, and the compression spring 27 is stretched. When the tension suddenly decreases or disappears, the compression spring 27 will drive the detection roller 25 to move backward, which means that the aluminum foil is broken. Fifth, when the aluminum foil on one pay-off roller 11 breaks, in order not to interrupt production, the aluminum foil on the other pay-off roller 11 can be used to continue the operation, and the moving block 232 can be pushed to move on the fixed block 23. The two ends of the limit hole 231 can make the detection frame 21 correspond to the middle position of the two pay-off rollers 11. Through the limitation of the limit hole 231, the moving block 232 can be quickly and accurately moved to the middle position of the other pay-off roller 11. After moving to the middle position of the new pay-off roller 11, the aluminum foil can smoothly pass through the detection roller 25, and the tension detection of the aluminum foil can be quickly restored; Sixth, after the electromagnetic disk 32 is energized, a magnetic field is generated, which produces a mutually repelling force with the magnetic block column 34, pushing the magnetic block column 34 to move to the outside of the telescopic slot, so that the clamping disk 35 approaches the pay-off roller 11, and finally the clamping disk 35 is tightly attached to the pay-off roller 11, so that the pay-off roller 11 can be quickly stopped.
