Description

Technical Field

[0001] The present invention relates to the technical field of mica tape winding machines, and more particularly to a mica tape winding machine. Background Art

[0002] Mica tape is a high-performance insulation product for cables, offering excellent high-temperature and flame-retardant properties. However, after production and drying, mica tape needs to be wound and slit. This requires frequent manual replacement of the winding reels or rollers. Furthermore, existing mica tape winding machines often use bolted baffles to secure the trays holding the mica tape reels. This requires disassembly of multiple parts during replacement, resulting in low winding efficiency and potential safety hazards. Therefore, a mica tape winding machine is needed to address the issues raised in the aforementioned background technology. Summary of the Invention

[0003] To achieve the above object, the present invention provides the following technical solution: a mica tape winding machine, comprising:

[0004] Base, carrying the entire winding equipment;

[0005] A drive motor is provided on the base to provide power for the winding device;

[0006] The rotating device is fixed on the driving motor and is driven to rotate by the driving motor;

[0007] The transmission device is provided with three transmission devices in a circular distribution and is fixed on the rotating device;

[0008] A clamping device, fixed to the transmission device;

[0009] A limiting roller is fixed on the base and corresponds to the clamping device;

[0010] A mica tape reel is provided on the clamping device;

[0011] The cutter is spaced apart from the transmission device and is fixed on the rotating device.

[0012] Furthermore, preferably, the rotating device includes:

[0013] The rotating bevel gear is fixed on the rotating shaft of the driving motor and rotates continuously in the clockwise direction under the drive of the driving motor;

[0014] There are three surrounding bevel gears distributed in an annular pattern, which mesh with the rotating bevel gear and are fixedly connected to the transmission device. Driven by the rotating bevel gear, the surrounding bevel gears rotate counterclockwise.

[0015] A fixed bevel gear is rotatably disposed on the rotating shaft of the drive motor and is fixed to the housing of the drive motor;

[0016] The fixed inner housing is rotatably mounted on the fixed bevel gear and is located outside the surrounding bevel gear to limit the positions of the surrounding bevel gear and the rotating bevel gear.

[0017] The limiting housing is fixed on the periphery of the fixed bevel gear.

[0018] Furthermore, preferably, the limiting shell is composed of three spaced arc surfaces, and the notch corresponds to the transmission device, and the limiting shell is located between the drive motor and the transmission device. When the transmission device rotates around the shaft of the drive motor, the rotation trajectory of the transmission device is above the limiting shell.

[0019] Furthermore, preferably, the transmission device includes:

[0020] The telescopic shaft passes through the fixed inner shell and is fixed on the surrounding bevel gear, and rotates under the drive of the surrounding bevel gear;

[0021] The transmission assembly is fixed to the extended end of the telescopic shaft, and the side surface is in contact with the side wall of the base. When the telescopic shaft is in the extended state, the transmission assembly is restricted by the base. When the rotating bevel gear drives the surrounding bevel gear to rotate, the surrounding bevel gear is kept in a fixed position, that is, the fixed inner shell is in a fixed state.

[0022] The transmission bevel gear is arranged corresponding to the fixed bevel gear and is fixed at one end of the telescopic shaft close to the transmission assembly. When the mica tape is wound, the telescopic shaft is in a retracted state under the action of the limiting roller. At this time, the transmission bevel gear is engaged with the fixed bevel gear, and the transmission assembly moves up to break away from the restriction of the base. Driven by the surrounding bevel gear, the transmission bevel gear drives the transmission assembly to rotate counterclockwise around the rotating shaft of the drive motor. During the rotation, the transmission bevel gear is restricted by the limiting housing and is always engaged with the fixed bevel gear until it rotates to the next notch of the limiting housing. Under the action of the telescopic shaft, the transmission bevel gear is reset.

[0023] Furthermore, as a preference, a return spring is provided on the telescopic shaft, and the return spring is located between the fixed inner shell and the transmission bevel gear. When the transmission bevel gear drives the transmission assembly to rotate from the bottom notch of the limiting outer shell to the next notch, the telescopic shaft extends under the action of the return spring, driving the transmission device to reset.

[0024] Furthermore, preferably, the transmission assembly includes:

[0025] The transmission shaft is fixed at the bottom of the transmission bevel gear and rotates along with the transmission bevel gear;

[0026] Bevel gear 1 is fixed at the bottom of the transmission shaft and rotates counterclockwise driven by the transmission shaft;

[0027] Bevel gear 2 is meshed with bevel gear 1 and is fixedly connected to the clamping device. Driven by bevel gear 1, bevel gear 2 drives the clamping device to rotate counterclockwise, thereby driving the mica tape reel to wind the mica tape.

[0028] Furthermore, preferably, three clamping devices are arranged in a ring-shaped distribution, corresponding to the limiting roller, the collecting device and the tape reel supply device in sequence. After the clamping device winds the mica tape at the bottom, it rotates counterclockwise under the action of the rotating device and the transmission device, and then reaches the collecting device. While rotating, the cutter cuts the mica tape, and then the clamping device puts down the wound mica tape reel. When the clamping device rotates again, it reaches the tape reel supply device, and the clamping device clamps a new mica tape reel. When it rotates next time, the clamping device returns to the position corresponding to the limiting roller to carry out the mica tape winding work.

[0029] Furthermore, preferably, the clamping device includes:

[0030] A rotating motor is arranged inside the clamping device;

[0031] The rotating disk is fixedly connected to the rotating motor and rotates under the drive of the rotating motor;

[0032] There are multiple clamping blocks distributed in a ring and set on the rotating disk. The two sides are slidably connected to the shell of the clamping device. When the rotating motor drives the rotating disk to rotate counterclockwise, the clamping blocks are driven to move toward the center of the clamping device on the shell, and then the mica tape reel is lowered. When the rotating motor drives the rotating disk to rotate clockwise, the clamping blocks are driven to move toward the periphery of the clamping device on the shell, so that the inner wall of the mica tape reel fits with the clamping blocks, and then the mica tape reel is fixed.

[0033] Compared with the prior art, the present invention has the following beneficial effects:

[0034] In the present invention, by setting up the rotating device and the transmission device, with the cooperation of multiple bevel gears, the winding and removal of the mica tape and the installation of the tape reel form a closed loop, the mica tape is continuously wound, and the working efficiency is greatly improved.

[0035] In the present invention, the mica tape reel is automatically clamped and lowered by setting a clamping device, and under the action of the telescopic shaft and the limiting roller, when the mica tape is wound to a certain thickness, it is rotated and replaced by the rotating device and the transmission bevel gear, and the winding work of the mica tape is continuously carried out.

[0042] See also Figures 1 to 5 In an embodiment of the present invention, a mica tape winding machine is provided, which includes a base 1, a drive motor 2, a rotating device 3, a transmission device 4, a clamping device 5, a limiting roller 6, a mica tape reel 7 and a cutter 8. The base 1 carries the entire winding device, the drive motor 2 is arranged on the base 1 to provide power for the winding device, the rotating device 3 is fixed to the drive motor 2 and is driven to rotate by the drive motor 2, three transmission devices 4 are arranged in a ring distribution and are fixed to the rotating device 3, the clamping device 5 is fixed to the transmission device 4, the limiting roller 6 is fixed to the base 1 and corresponds to the clamping device 5, the mica tape reel 7 is arranged on the clamping device 5, and the cutter 8 is arranged at a distance from the transmission device 4 and is fixed to the rotating device 3.

[0043] In this embodiment, the rotating device 3 includes a rotating bevel gear 31, a surrounding bevel gear 32, a fixed bevel gear 33, a fixed inner shell 34 and a limiting outer shell 35. The rotating bevel gear 31 is fixed on the rotating shaft of the driving motor 2 and rotates continuously in the clockwise direction under the drive of the driving motor 2. Three surrounding bevel gears 32 are distributed in an annular manner and mesh with the rotating bevel gear 31. They are also fixedly connected to the transmission device 4. Driven by the rotating bevel gear 31, the surrounding bevel gear 32 rotates counterclockwise. The fixed bevel gear 33 is rotatably set on the rotating shaft of the driving motor 2 and fixed on the outer shell of the driving motor 2. The fixed inner shell 34 is rotatably set on the fixed bevel gear 33 and is located on the periphery of the surrounding bevel gear 32 to limit the positions of the surrounding bevel gear 32 and the rotating bevel gear 31. The limiting outer shell 35 is fixed to the periphery of the fixed bevel gear 33.

[0044] In this embodiment, the limiting shell 35 is composed of three arc surfaces arranged at intervals, and the notch corresponds to the transmission device 4, and the limiting shell 35 is located between the drive motor 2 and the transmission device 4. When the transmission device 4 rotates around the rotating shaft of the drive motor 2, the rotation trajectory of the transmission device 4 is above the limiting shell 35.

[0045] In this embodiment, the transmission device 4 includes a telescopic shaft 41, a transmission assembly 42 and a transmission bevel gear 43. The telescopic shaft 41 passes through the fixed inner shell 34 and is fixed on the surrounding bevel gear 32. It rotates under the drive of the surrounding bevel gear 32. The transmission assembly 42 is fixed to the protruding end of the telescopic shaft 41, and the side surface is in contact with the side wall of the base 1. When the telescopic shaft 41 is in the extended state, the transmission assembly 42 is restricted by the base 1. When the rotating bevel gear 31 drives the surrounding bevel gear 32 to rotate, the surrounding bevel gear 32 is kept in a fixed position, that is, the fixed inner shell 34 is in a fixed state. The transmission bevel gear 43 is correspondingly arranged with the fixed bevel gear 33 and is fixed to the telescopic shaft. 41 is close to one end of the transmission assembly 42. When the mica tape is wound, under the action of the limiting roller 6, the telescopic shaft 41 is in a retracted state. At this time, the transmission bevel gear 43 is engaged with the fixed bevel gear 33, and the transmission assembly 42 moves up to break away from the restriction of the base 1. Driven by the surrounding bevel gear 32, the transmission bevel gear 43 drives the transmission assembly 42 to rotate counterclockwise around the rotating shaft of the drive motor 2. During the rotation, the transmission bevel gear 43 is restricted by the limiting housing 35 and is always engaged with the fixed bevel gear 33 until it rotates to the next notch of the limiting housing 35. Under the action of the telescopic shaft 41, the transmission bevel gear 43 is reset.

[0046] In this embodiment, a return spring is provided on the telescopic shaft 41, and the return spring is located between the fixed inner shell 34 and the transmission bevel gear 43. When the transmission bevel gear 43 drives the transmission assembly 42 to rotate from the bottom notch of the limiting outer shell 35 to the next notch, under the action of the return spring, the telescopic shaft 41 extends, driving the transmission device 4 to reset.

[0047] In this embodiment, the transmission assembly 42 includes a transmission shaft 421, a bevel gear 1 422 and a bevel gear 2 423. The transmission shaft 421 is fixed at the bottom of the transmission bevel gear 43 and rotates along with the transmission bevel gear 43. The bevel gear 1 422 is fixed at the bottom of the transmission shaft 421 and rotates counterclockwise under the drive of the transmission shaft 421. The bevel gear 2 423 is meshed with the bevel gear 1 422 and is fixedly connected to the clamping device 5. Driven by the bevel gear 1 422, the bevel gear 2 423 drives the clamping device 5 to rotate counterclockwise, thereby driving the mica tape reel 7 to wind the mica tape.

[0048] In this embodiment, three clamping devices 5 are distributed in a ring, corresponding to the limiting roller 6, the collecting device and the tape reel supply device in sequence. After the clamping device 5 winds the mica tape at the bottom, it rotates counterclockwise under the action of the rotating device 3 and the transmission device 4, and then reaches the collecting device. While rotating, the cutter 8 cuts the mica tape, and then the clamping device 5 puts down the wound mica tape reel 7. When the clamping device 5 rotates again, it reaches the tape reel supply device, and the clamping device 5 clamps the new mica tape reel 7. When it rotates next time, the clamping device 5 returns to the position corresponding to the limiting roller 6 to carry out the mica tape winding work.

[0049] In this embodiment, the clamping device 5 includes a rotating motor 51, a rotating disk 52 and a clamping block 53. The rotating motor 51 is arranged inside the clamping device 5, and the rotating disk 52 is fixedly connected to the rotating motor 51 and rotates under the drive of the rotating motor 51. There are multiple clamping blocks 53 distributed in an annular manner, which are arranged on the rotating disk 52, and are slidably connected to the shell of the clamping device 5 on both sides. When the rotating motor 51 drives the rotating disk 52 to rotate counterclockwise, it drives the clamping block 53 to move toward the center of the clamping device 5 on the shell, and then lowers the mica tape reel 7. When the rotating motor 51 drives the rotating disk 52 to rotate clockwise, it drives the clamping block 53 to move toward the periphery of the clamping device 5 on the shell, so that the inner wall of the mica tape reel 7 fits with the clamping block 53, and then fixes the mica tape reel 7.

[0050] During the specific implementation, the clamping device 5 with the mica tape reel 7 is first fixed in a relative position with the limiting roller 6, and the mica tape enters between the mica tape reel 7 and the limiting roller 6 from the left side. The clamping device 5 rotates continuously under the drive of the transmission component 42 to wind the mica tape. As the winding thickness of the mica tape continues to increase and under the restriction of the limiting roller 6, the telescopic shaft 41 contracts until the transmission bevel gear 43 engages with the fixed bevel gear 33. At this time, the transmission component 42 breaks away from the restriction of the base 1. Driven by the surrounding bevel gear 32, the transmission bevel gear 43 drives the transmission component 42 to rotate counterclockwise around the rotating shaft of the drive motor 2. During the rotation process, the transmission bevel gear 43 is restricted by the limiting shell 35 and is always engaged with the fixed bevel gear 33 until it rotates to the next notch of the limiting shell 35, that is, it rotates to the collecting device. Under the action of the telescopic shaft 41 , the transmission bevel gear 43 is reset, and while rotating, the cutter 8 cuts the mica tape. At the collecting device, the rotating motor 51 in the clamping device 5 drives the rotating disk 52 to rotate counterclockwise, driving the clamping block 53 to move toward the center of the clamping device 5 on the shell, and then puts down the wound mica tape reel 7. At this time, the next clamping device 5 performs winding work at the limiting roller 6. When the clamping device 5 rotates again, the first clamping device 5 for winding rotates to the tape reel supply device, and the rotating motor 51 drives the rotating disk 52 to rotate clockwise, driving the clamping block 53 to move toward the periphery of the clamping device 5 on the shell, thereby making the inner wall of the new mica tape reel 7 fit and fix it with the clamping block 53. When the rotating device 3 drives the transmission device 4 and the clamping device 5 to rotate continuously, multiple clamping devices 5 perform the mica tape winding work in turn.

[0051] The above is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with this technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solutions and inventive concepts of the present invention, should be covered by the scope of protection of the present invention.
