Description

Technical Field

[0001] This utility model relates to the field of cable production technology, specifically to a cable wrapping machine. Background Technology

[0002] Cables are wire products used to transmit electrical (magnetic) energy, information, and to achieve electromagnetic energy conversion. Cables are typically rope-like structures made of one or more stranded conductors, completely covered with a highly insulating outer layer. During cable production, a wrapping machine uses a rotating turntable to wrap wrapping tape (mica tape, cotton paper tape, aluminum foil, polyester film, etc.) around the core wire, thus protecting and insulating the cable itself. In existing technology: Authorization Publication No. CN 222507237 U's patent discloses a cable wrapping machine, including a machine body and a positioning assembly. The positioning assembly includes two sets of annular components located at opposite ends of the machine body. A movable plate is arranged in a ring at equal intervals in the middle of each annular component. Positioning wheels for clamping and pressing the core wire are located on the inner bottom wall of the movable plate. A toothed plate for vertically driving the movable plate is detachably installed inside the movable plate. Through the interaction of the annular components, electric telescopic rod, positioning wheels, drive shaft, first gear, toothed plate, movable plate, toothed belt, and second gear, and utilizing a partial support method, the core wire in the wrapping area can be... The cable body is centered and positioned, reducing the sag of the core wire body in the wrapping area and decreasing the probability of loose wrapping tape. Through the cooperation of the adapter shaft, movable block, guide groove, fastening spring, guide rod and rubber wheel, the pressing pressure of the positioning wheel can be buffered. However, this device wraps the wrapping tape around the outer ring of the cable, and then the cable wrapping is completed. The cable is traction and transported by an external traction device. During traction, the cable body jumps. When the mica tape wraps on the jumping cable, it will not wrap tightly, affecting the neatness and tightness of the cable wrapping. To address this, we propose a wrapping machine for cable production. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the existing defects and provide a cable wrapping machine. This device uses elastic elements and guiding elements to ensure that the mica tape wrapping part is always in accurate contact with the outer surface of the cable, ensuring that the cable wrapping is neat and tight. At the same time, the device uses elastic elements to ensure that the mica tape feeding part is always in a taut state during the cable wrapping process, avoiding the loosening of the mica tape in this part and the subsequent loosening of the cable wrapping. This can effectively solve the problems in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a cable wrapping machine, including a wrapping shell, a rotating disk rotatably connected to the front side of the wrapping shell via a large-diameter bearing, two symmetrically distributed feeding disks rotatably connected to the front side of the rotating disk via a rotating shaft, and an auxiliary mechanism;

[0005] Auxiliary mechanism: It includes a slide, a telescopic column, a spring, a fixed shaft, an auxiliary rod, an annular inner groove, and a tensioning assembly. The slides are slidably connected to dovetail grooves symmetrically opened on the front side of the rotating disk. Each slide has an auxiliary rod on its front side via a fixed shaft. Each auxiliary rod has an annular inner groove on its outer side. A telescopic column and a spring are provided between the dovetail groove and the adjacent slide. The spring is movably sleeved with the outer end of the adjacent telescopic column. A tensioning assembly is provided between the rotating disk and the rotating shaft. This device, through elastic and guiding elements, ensures that the mica tape winding part is always in accurate contact with the outer surface of the cable, ensuring the neatness and tightness of the cable wrapping. At the same time, through elastic elements, the device ensures that the mica tape unwinding part is always in a taut state during the cable wrapping process, preventing the subsequent cable wrapping from becoming loose due to the loose mica tape in this part.

[0006] Furthermore, a microcontroller is provided on the upper right side of the casing. The input terminal of the microcontroller is electrically connected to an external power supply, making it convenient to control electrical components.

[0007] Furthermore, the auxiliary mechanism also includes heating strips, which are evenly arranged inside the annular inner groove. The input ends of the heating strips are electrically connected to the output end of the microcontroller to heat and soften the mica tape wrapped around the outside of the cable, thereby making it easier for the mica tape to wrap more closely around the outside of the cable.

[0008] Furthermore, the tensioning assembly includes a fixed seat, a telescopic rod, a second spring, a locking tooth seat, and a first gear. The fixed seats are respectively located at the left and right ends of the front side of the rotating disk. The opposing surfaces of the two fixed seats are equipped with locking teeth seats through two symmetrically distributed telescopic rods and the second spring. The second spring is movably sleeved with the outer end of the adjacent telescopic rod. The rear end of the first rotating shaft is equipped with a first gear. The locking tooth seats are installed in cooperation with the adjacent first gear, so that the material feeding part of the mica tape is always in a taut state, avoiding the loosening of the mica tape in this part, which would cause the subsequent cable wrapping to become loose.

[0009] Furthermore, a gear two is rotatably connected to the front side of the wrapping shell via a rotating shaft two, and an external gear ring is provided on the outer side of the rotating disk. The gear two meshes with the external gear ring. A motor is provided on the front wall of the wrapping shell. The input end of the motor is electrically connected to the output end of the microcontroller. The output shaft of the motor is fixedly connected to the rear end of the rotating shaft two, providing power for the device to wrap the cable.

[0010] Furthermore, mounting seats are provided at both the left and right ends of the lower side of the wrapping shell, and two reinforcing ribs are provided between the mounting seats and the wrapping shell to improve the service life of the wrapping machine used for cable production.

[0011] Furthermore, the central circular holes on both the front and rear walls of the wrapping shell are provided with evenly distributed semicircular grooves, and rotating balls are rotatably connected inside the semicircular grooves to reduce the sliding wear between the inner circular holes of the wrapping machine for cable production and the cable conveying movement.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: This cable production wrapping machine has the following advantages:

[0013] When using a cable wrapping machine, the mica tape winding part is always in accurate contact with the outer surface of the cable through the slide, telescopic column, spring, fixed shaft, auxiliary rod and annular inner groove, ensuring that the cable wrapping is neat and tight. At the same time, the device uses a tensioning component to keep the mica tape unwinding part in a taut state during the cable wrapping process, preventing the mica tape in this part from loosening and causing subsequent cable wrapping to become loose.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-4 This embodiment provides a technical solution: a cable wrapping machine, including a wrapping shell 1. A rotating disk 3 is rotatably connected to the front side of the wrapping shell 1 via a large-diameter bearing. Two symmetrically distributed feeding disks 5 are rotatably connected to the front side of the rotating disk 3 via a rotating shaft 4. A microcontroller 2 is provided at the upper right side of the wrapping shell 1. The input terminal of the microcontroller 2 is electrically connected to an external power supply. Mounting seats 10 are provided at both the left and right ends of the lower side of the wrapping shell 1. Two reinforcing ribs 11 are provided between the mounting seats 10 and the wrapping shell 1. Uniformly distributed semi-circular grooves are opened in the central circular holes of the front and rear walls of the wrapping shell 1. Rotating balls 12 are rotatably connected inside the semi-circular grooves. The device is fixed to the designated position by bolts through the mounting base 10. The structural strength of the device itself is improved by the reinforcing rib 11, thereby improving the service life of the device. When the wrapping machine is used to perform wrapping operation on the cable production, the cable passes through the round hole in the middle of the device from back to front through the external material feeding device. Mica tape is wrapped on the feeding tray 5. The rotating ball 12 limits the contact of the cable passing through the device. The rotating ball 12 rotates adaptively around the corresponding semicircular groove. The rotating ball 12 separates the cable from the round hole at the corresponding part to avoid scratches caused by hard sliding contact between the cable and the round hole. It also includes an auxiliary mechanism 6.

[0021] Auxiliary mechanism 6 includes a slide 61, a telescopic column 62, a spring 63, a fixed shaft 64, an auxiliary rod 65, an annular inner groove 66, and a tensioning assembly 68. The slides 61 are slidably connected to dovetail grooves symmetrically opened on the front side of the rotating disk 3. Each slide 61 has an auxiliary rod 65 on its front side via the fixed shaft 64. An annular inner groove 66 is opened on the outer side of each auxiliary rod 65. A telescopic column 62 and a spring 63 are provided between the dovetail groove and the adjacent slide 61. The spring 63 is movably sleeved with the outer end of the adjacent telescopic column 62. A tensioning assembly 68 is provided between the rotating disk 3 and the rotating shaft 4. Auxiliary mechanism 6 also includes heating strips 67, which are evenly arranged inside the annular inner grooves 66. The input ends of the heating strips 67 are electrically connected to the output end of the microcontroller 2. The tensioning assembly 68 includes a fixed seat 681, a telescopic column 62, a spring 63, a fixed shaft 64, an auxiliary rod 65, an annular inner groove 66, and a tensioning assembly 68. The telescopic rod 682, spring 683, tooth holder 684, and gear 685 are respectively located on the left and right sides of the front side of the rotating disk 3. The opposing surfaces of the two fixed seats 681 are equipped with tooth holders 684 via two symmetrically distributed telescopic rods 682 and springs 683. Springs 683 are movably sleeved with the outer ends of adjacent telescopic rods 682. Gears 685 are located at the rear ends of rotating shafts 4, and tooth holders 684 are fitted with adjacent gears 685. Gear 7 is rotatably connected to the front side of the casing 1 via rotating shaft 2. An external gear ring 8 is located on the outer side of the rotating disk 3, and gear 7 meshes with the external gear ring 8. A motor 9 is located around the front wall of the casing 1. The input end of motor 9 is electrically connected to the output end of the microcontroller 2, and the output shaft of motor 9 is fixedly connected to the rear end of rotating shaft 2. The initial end of the mica belt is then... Figure 3The mica tape wrapped around the cable at corresponding locations is positioned by an annular groove 66 to limit the wrapping point, preventing deviation of the mica tape during cable wrapping. Spring 63 remains compressed, and its compression force causes slide 61 to indirectly drive auxiliary rod 65 towards the center of the device. This ensures the mica tape within the annular groove 66 presses against and wraps around the outer surface of the cable, improving the neatness of the mica tape wrapping. The microcontroller 2 starts motor 9, causing its output shaft to... The rotating shaft 2 drives the gear 2 7 to rotate forward. The gear 2 7, through its meshing connection with the external gear ring 8, causes the rotating disk 3 to rotate forward. The rotating disk 3 drives the corresponding feeding disk 5 to rotate synchronously. During this process, as the initial end of the mica tape wraps around the outer side of the cable, the tension between the mica tape and the corresponding feeding disk 5 gradually increases. When the tension reaches a certain level, this force overcomes the elastic locking force exerted by the spring 2 683 on the tooth holder 684 and the adjacent gear 1 685, causing the gear 1 685 to move out of alignment with the corresponding tooth holder 684. The feeding disk 5 rotates around the corresponding rotating shaft 1 The four-axis rotation automatically tensions and releases the mica tape, ensuring it remains taut throughout the release process. This improves the neatness of the mica tape wrapping around the cable. Simultaneously, the microcontroller 2 activates the heating strip 67 to heat and soften the mica tape within the annular groove 66, enhancing the wrapping and adhesion between the mica tape and the cable. During this process, the microcontroller 2 controls the output power of the heating strip 67 to prevent excessive heating of the mica tape at the corresponding locations. The slip ring can be divided into two parts: a conductive slip ring and a connecting ring. The contact point is where a conductive slip ring is fixedly mounted on the rotating disk 3, and the contact point is laid on the front side of the wrapping shell 1. The heating strip 67 is electrically connected to the microcontroller 2 through a collector ring. The collector ring prevents the heating strip 67 from winding during the rotation of the rotating disk 3. The device uses elastic and guiding elements to ensure that the mica tape winding part is always in accurate contact with the outer surface of the cable, ensuring the neatness and tightness of the cable wrapping. At the same time, the device uses elastic elements to ensure that the material release part of the mica tape is always in a taut state during the cable wrapping process, preventing the subsequent cable wrapping from becoming loose due to the looseness of the mica tape in this part.

[0022] The working principle of the cable wrapping machine provided by this utility model is as follows: The device is fixed to the designated position by bolts through the mounting base 10. The structural strength of the device is improved by the reinforcing ribs 11, thereby improving the service life of the device. When the wrapping machine is used to perform the wrapping operation on the cable, the cable passes through the circular hole in the middle of the device from back to front through the external material feeding device. Mica tape is wound on the feeding tray 5. The initial end of the mica tape is arranged according to... Figure 3The mica tape wrapped around the cable at corresponding locations is positioned by an annular groove 66 to limit the wrapping point, preventing deviation of the mica tape during cable wrapping. Spring 63 remains compressed, and its compression force causes slide 61 to indirectly move the auxiliary rod 65 towards the center of the device. This ensures the mica tape within the annular groove 66 presses against and wraps around the outer surface of the cable, improving the neatness of the mica tape wrapping. The microcontroller 2 starts motor 9. The output shaft drives gear 7 to rotate forward via shaft 2. Gear 7 meshes with the external gear ring 8, causing the rotating disk 3 to rotate forward. The rotating disk 3 drives the corresponding feeding disk 5 to rotate synchronously. During this process, as the initial end of the mica tape wraps around the outer side of the cable, the tension between the mica tape and the corresponding feeding disk 5 gradually increases. When the tension reaches a certain level, it overcomes the elastic locking force exerted by spring 2 683 on the tooth holder 684 and the adjacent gear 1 685, causing a misalignment between gear 1 685 and the corresponding tooth holder 684. The feeding disc 5 rotates around the corresponding rotating shaft 4, automatically tensioning and feeding the mica tape. By keeping the mica tape taut throughout the feeding process, the neatness of the mica tape wrapping around the outside of the cable is further improved. Simultaneously, the microcontroller 2 activates the heating bar 67 to heat and soften the mica tape within the annular groove 66, thereby improving the wrapping and adhesion between the mica tape and the outside of the cable. During this process, the microcontroller 2 controls the output power of the heating bar 67 to prevent excessive heating of the mica tape at the corresponding location. This is achieved through the rotating ball... 12. The cable of the device is contacted and limited. The rotating ball 12 rotates adaptively around the corresponding semicircular groove. The rotating ball 12 separates the cable from the corresponding circular hole to avoid scratches caused by hard sliding contact between the cable and the circular hole. The collector ring can be divided into two parts: one part is a conductive slip ring and the other part is a connecting contact point. The conductive slip ring is fixedly sleeved on the rotating disk 3, and the connecting contact point is laid on the front side of the wrapping shell 1. The heating strip 67 is electrically connected to the microcontroller 2 through the collector ring. The collector ring prevents the heating strip 67 from winding during the rotation of the rotating disk 3.

[0023] It is worth noting that the microcontroller 2 disclosed in the above embodiments can be a COP8CBE9, the heating strip 67 can be an MCH ceramic heating element, and the motor 9 can be a Y80M1-2. The microcontroller 2 controls the operation of the heating strip 67 and the motor 9 using methods commonly used in the prior art.

Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
