Technical Field
[0001] This utility model relates to the field of cable wrapping technology, specifically to a mica tape wrapping machine. Background Technology
[0002] Mica tape wrapping machines are key equipment widely used in the manufacture of power cable insulation layers. Their technological development stems from the power industry's demand for efficient and precise processing of high-performance insulation materials. In early cable manufacturing, mica tape wrapping relied heavily on manual or semi-automatic machinery, resulting in problems such as low wrapping speed, uneven tension, and loose interlayer bonding. This easily led to mica tape misalignment, wrinkles, or air bubbles, severely affecting the insulation layer's high-temperature and voltage resistance. With the increasing demand for high-voltage cables, new energy equipment, and special cables, modern wrapping machines, through the integration of precision tension control systems, multi-axis cooperative motion algorithms, and real-time correction technology, have achieved constant tension and high-precision spiral wrapping of mica tape on the conductor surface. Simultaneously, combined with a temperature control module to optimize adhesive curing, this significantly improves the uniformity and reliability of the insulation layer. The technological evolution of this type of equipment reflects the transformation of cable manufacturing from labor-intensive to automated and intelligent processes, and it has become one of the core equipment for high-end cable production in new energy power generation, rail transportation, and aerospace fields.
[0003] The invention patent with application number CN202510170003.8 and publication number CN119724767A (hereinafter referred to as "Prior Art 1") discloses a cable wrapping machine for a wire harness production line, including a base. A first support block is fixedly connected to the upper end of the base. The outer ring of a first bearing is fixedly connected to the upper end of the first support block. A first disc is fixedly connected to the inner ring of the first bearing. Three first connecting blocks are slidably connected inside the first disc. A round rod is fixedly connected to one end of each of the three first connecting blocks. A cleaning mechanism is provided at one end of each of the three round rods. A limiting mechanism for supporting the cable is provided on the surface of the first connecting block. A winding mechanism for wrapping the cable is provided at the upper end of the base.

[0004] The specification of prior art 1 discloses a cable wrapping machine for a wire harness production line. In use, the cable is wrapped by a mica tape on a roller.

Detailed Implementation
[0025] The present invention will be further described below with reference to the embodiments. The described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, other embodiments obtained by those skilled in the art without creative effort are all within the protection scope of the present invention.
[0026] Please see Figure 1-3 As shown, this embodiment discloses a mica tape wrapping machine, including a support frame 101, a cable winding and unwinding device, and a wrapping device; the support frame 101 is used to be installed on a plane; the cable winding and unwinding device is used to wind and unwind the cable body 102; the wrapping device is installed on the support frame 101, and is used to wind the mica tape body 103 and wrap the cable body 102 passing through the wrapping device.
[0027] The support frame 101 is hinged with a stabilizing component, which includes a hinge frame 104, a pressure roller 105, and a torsion spring. The hinge frame 104 is hinged to the support frame 101, the pressure roller 105 is rotatably mounted on the hinge frame 104, and the torsion spring is sleeved on the hinge frame 104. One end of the torsion spring is fixedly connected to the hinge frame 104, and the other end is fixedly connected to the support frame 101.
[0028] This utility model mainly includes a support frame 101, a cable winding and unwinding device, and a wrapping device. In actual use, the mica tape body 103 is first loaded onto the wrapping device, and then the cable body 102 is installed on the cable winding and unwinding device. The end of the cable body 102 is held by hand to fix the mica tape body 103 to the end of the cable body 102. Then, the cable winding and unwinding device and the wrapping device are started to complete the wrapping of the cable body 102. During this process, the operator needs to pull up the hinge frame 104, and then the torsion of the torsion spring causes the hinge frame 104 to automatically reset. At this time, the pressure roller 105 rotates with the hinge frame 104. Finally, the pressure roller 105 presses on the cable winding and unwinding device. When the cable body 102 is pulled, it slides with the pressure roller 105. At the same time, the pressure roller 105 is subjected to the torsion of the torsion spring, which can also limit the cable body 102, making it difficult for the cable body 102 to fall off the cable winding and unwinding device.
[0029] In some embodiments, the cable winding and unwinding device includes a roller 107, a mounting frame 108, a tensioning structure, a winding reel 109, and a driving structure.

The tensioning structure is mounted on a support frame and is used to wind the cable body 102 onto the winding reel 109 after passing through the tensioning structure and the wrapping device. The driving structure is used to drive the roller 107 and the winding reel 109 to rotate synchronously.
[0030] In actual use, during the winding and unwinding of the cable body 102, the cable body 102 wound on the roller 107 is first pulled out, passes around the tensioning structure, and then enters the wrapping device. Then, the mica tape body 103 is fixed to the end of the cable body 102. Then, the cable body 102 is pulled to fix the cable body 102 to the winding reel 109. Finally, the cable body 102 on the roller 107 is wound onto the winding reel 109 by the rotation of the drive structure. During this process, the wrapping device rotates at high speed, thereby winding the mica tape onto the cable body 102 and completing the winding of the cable body 102.
[0031] In some embodiments, the tensioning structure includes a mounting strip 110, a movable frame 111, and a tensioning wheel 112. The mounting strip 110 is mounted on the support frame 101 and has a plurality of mounting holes 113. The movable frame 111 is detachably mounted on the mounting holes 113 on the mounting strip 110. The tensioning wheel 112 is rotatably mounted on the end of the movable frame 111. The cable body 102 is used to pass around the tensioning wheel 112 and connect to the winding reel 109.
[0032] In actual use, when tensioning the cable body 102, the mounting strip 110 needs to be installed on the support frame 101, and then the position of the movable frame 111 is adjusted on the mounting strip 110 until the tensioning wheel 112 tensions the cable body 102. Then the movable frame 111 is fixed on the mounting hole 113. There are several movable frames 111, and all of them are installed on the mounting strip 110 through the mounting hole 113.
[0033] In some embodiments, the drive structure includes a first motor 114 and a second motor 115. Both the first motor 114 and the second motor 115 are mounted on the support frame 101. The output shaft of the first motor 114 is fixedly connected to the roller 107 and is used to drive the roller 107 to rotate. The output shaft of the second motor 115 is fixedly connected to the take-up reel 109 and is used to drive the take-up reel 109 to rotate.
[0034] In actual use, the first motor 114 and the second motor 115 control the roller 107 and the winding reel 109 to rotate at the same speed, thereby realizing the winding and unwinding of the cable body 102.
[0035] In some embodiments, the hinge frame 104 is hinged to the mounting frame 108 via a pivot 116, and the torsion spring is sleeved on the pivot 116. One end of the torsion spring is connected to the hinge frame 104, and the other end is fixedly connected to the mounting frame 108.
[0036] In actual use, the purpose of setting the pivot 116 is to facilitate the installation of the torsion spring by the staff.
[0037] In some embodiments, the wrapping device includes a motor 117, a mounting base 106, and a turntable 118. The fixed end of the motor 117 is mounted on a support frame 101. The mounting base 106 is fixedly mounted on the support frame 101 and located above the tensioning structure. The turntable 118 is rotatably mounted on the mounting base 106. The motor 117 is connected to the turntable 118 via a rotating mechanism. The motor 117 drives the turntable 118 to rotate on the mounting base 106. A mica tape winding cylinder 119 is provided on the turntable 118. The mica tape winding drum is used to wind the mica tape body 103. A fixing frame 120 is also provided on the turntable 118. A limiting cylinder 121 is provided on the fixing frame 120. The limiting cylinder 121 has openings at both ends and is used to pass through the fixing frame 120.

The cable body 102 is used to pass through the clearance holes and is fixed on the winding reel 109.
[0038] In actual use, after the motor 117 rotates, it drives the turntable 118 to rotate on the mounting base 106. After the turntable 118 rotates, it drives the fixing frame 120 and the mica tape winding drum to rotate synchronously. When the fixing frame 120 rotates, the mica tape body 103 passes through the limiting tube 121 and wraps around the cable body 102. There are several limiting tubes 121, and several limiting tubes 121 are arranged in a circumferential array on the fixing frame 120. The number and position of the limiting tubes 121 correspond to the mica tape winding drum. When wrapping the cable body 102, as the mounting base 106 rotates continuously, the mica tape body 103 is released from the mica tape winding drum and wrapped around the cable body 102 through the limiting tubes 121.
[0039] In some embodiments, the transmission mechanism includes a drive pulley 122, a mounting groove, and a belt 123. The drive pulley 122 is fixedly mounted on the output shaft of the motor 117, the mounting groove is provided on the side of the turntable 118, and the belt 123 is sleeved inside the drive pulley 122 and the mounting groove.
[0040] In actual use, after the motor 117 rotates, it drives the drive pulley 122 to rotate. After the drive pulley 122 rotates, it drives the turntable 118 to rotate on the mounting base 106 under the action of the friction of the belt 123, thereby achieving the purpose of the motor 117 rotating to drive the turntable 118 to rotate.
[0041] In some embodiments, the tensioning structure further includes a movable panel 124 and a telescopic structure 125. The movable panel 124 is slidably mounted on the support frame 101, and the mounting strip 110 is fixedly mounted on the movable panel 124. The telescopic structure 125 is disposed on the support frame 101, and the end of the telescopic structure 125 is fixedly connected to the movable panel 124. The telescopic structure 125 is used to drive the movable panel 124 to slide on the support frame 101.
[0042] In actual use, in order to further adjust the tension of the cable body 102, a telescopic structure 125 is set to push the movable panel 124 to slide on the support frame 101, so that the tensioning wheel 112 can better tension the cable body 102.
[0043] In some embodiments, the telescopic structure 125 is an electrically operated telescopic structure 125, a pneumatically operated telescopic structure 125, or a hydraulically operated telescopic structure 125.
