Description

Technical Field

[0001] This utility model relates to the field of bare conductor insulation protection treatment technology, specifically an improved automatic wrapping device for bare conductor insulation tape. Background Technology

[0002] In power system operation and maintenance, insulating bare conductors is a critical task.

[0003] Chinese invention patent CN115410777B (titled "A Tape Wrapping Device for Bare Wires") discloses a technical solution related to insulation protection treatment of bare wires. According to the specification and drawings of the aforementioned patent document, it can achieve automatic wrapping of tape on bare wires. However, the following problems still exist in the tape wrapping process:

[0004] 1. During the tape winding process, the high degree of flexibility of the insulating tape roll makes it impossible to achieve an auxiliary tension at the tape output end. At the same time, during the process of the tape winding around the bare conductor, there is no tape pressing mechanism on the wrapping plate, which results in insufficient adhesion between the insulating tape and the bare conductor, reducing the insulation protection effect.

[0005] 2. After wrapping the tape, manual operation is required to detach the fixing shell from the bare wire. Then, the tape is cut using a tape cutter. The tape cutting method described above makes it impossible for the end of the tape to adhere to the bare wire, resulting in imperfect tape wrapping. In some specific cases, it is still necessary to manually wrap the end of the tape around the bare wire. Utility Model Content

[0006] The purpose of this invention is to provide an improved automatic wrapping device for insulating tape on bare conductors. When using this device to automatically wrap insulating tape on bare conductors, the tape output from the tape roll is in a stretched state, and the pressure tongue can press the tape against the bare conductor again, thereby achieving a tight fit between the tape and the bare conductor. The tape cutting mechanism can automatically cut the tape, and after cutting, the tape wrapping process is repeated, allowing the end of the tape to fit against the bare conductor. This improves the aesthetics of the tape wrapping and eliminates the need for manual assistance in fitting the tape end, thus improving the efficiency of automatic tape wrapping.

Under the push of the first spring, the left end of the first locking rod can be stably engaged in the first trapezoidal through-hole. Furthermore, the upper arc-shaped surface of the left end of the first locking rod is higher than the bottom arc-shaped surface of the first U-shaped slot. The lower middle part of the pressure tongue is hinged to the lower right side of the first U-shaped slot, and the upper part of the pressure tongue is fitted into the second through-hole. A latch is provided at the lower middle part of the pressure tongue. The right end of the first locking rod is locked in the latch under the push of the first spring. The upper part of the first tension spring is fixedly connected to the surrounding plate, and the lower part of the first tension spring is connected to the lower outer side of the pressure tongue. The first tension spring is always in a stretched state.

[0009] Furthermore, several freely rolling rubber rollers are provided on the upper part of the pressure tongue.

[0010] Furthermore, the tape cutting device includes a second locking rod, a second spring, a first torsion spring, a serrated cutting blade, a rotating seat, and an unlocking plate. A cutting fixing seat is provided on the upper left side of the first U-shaped slot, and a tape inlet is provided between the cutting fixing seats. The rotating seat is hinged to the left side of the cutting fixing seat via a support shaft. The first torsion spring is sleeved on the support shaft and always applies a downward swinging torque to the rotating seat. An arc-shaped groove is provided on the upper left side of the surrounding plate. The second locking rod is slidably sleeved in the arc-shaped groove, and the second spring is locked in the arc-shaped groove and is used to push the second locking rod to slide to the left. At the right end of the second locking rod... A locking groove is provided on the front side, and a limiting block adapted to the locking groove is provided at the rear left end of the rotating seat. When the limiting block is locked in the locking groove, the rotating seat is initially positioned. The serrated cutting blade is fixedly provided at the left end of the rotating seat, and the unlocking plate is fixedly provided on the upper left side of the fixed housing. A spring steel ball positioning plunger is fixedly provided at the left end area of ​​the second locking rod, with the steel ball of the spring steel ball positioning plunger facing the fixed housing. When the surrounding plate rotates clockwise, the unlocking plate can push the steel ball in the spring steel ball positioning plunger to retract. When the surrounding plate rotates counterclockwise, the unlocking plate can block the steel ball of the spring steel ball positioning plunger.

[0011] Furthermore, a steel ball retraction guide slope is provided on the lower left side of the unlocking plate.

[0012] Furthermore, the resistance adjustment mechanism includes a pressure plate, a fixed seat, and a top-pressing bolt. A pressure plate slot is provided on the annular plate on one side of the rotating drum of the tape mounting seat. The pressure plate is made of elastic metal material and is secured in the pressure plate slot. The lower right end of the pressure plate can move freely in the pressure plate slot. The fixed seat is provided on the annular plate, and the top-pressing bolt is provided on the fixed seat. By rotating the top-pressing bolt, the lower right end of the pressure plate can be pressed against the side wall of the rotating drum.

[0013] Preferably, an outer membrane collection assembly located on the left side of the first U-shaped locking groove is further provided on the surrounding plate.

The inner end of the spring is fixedly locked on the synchronous drive shaft.

[0014] The beneficial effects of this invention are as follows: During the tape winding process, the pressure tongue can apply pressure to the tape. Simultaneously, the resistance adjustment mechanism allows for adjustment of the rotational resistance of the tape roll. By appropriately adjusting the rotational resistance of the tape roll during winding, the tape remains in a taut state. Before winding, the tape is in a taut state; during winding, it is again pressed down by the pressure tongue, thus achieving a tight fit between the tape and the bare wire. The inversion of the wrapping plate releases the serrated cutter. After release, the serrated cutter's front teeth insert into the tape. Then, the wrapping plate rotates forward again. During this rotation, the tape is broken at the serrated cutter, resulting in automatic tape cutting. After the tape is cut, the wrapping plate rotates several more times to automatically wind the end of the tape onto the bare wire, thus improving the efficiency of automated tape winding. During the automatic tape winding process, the winding drum is driven by a spring, allowing it to rotate synchronously while the tape is continuously output. This achieves automatic winding and collection of the outer film of the tape, avoiding waste of the film and environmental pollution. Attached Figure Description

Detailed Implementation

[0030] The following will describe specific embodiments and appendices. Figure 1-13 The technical solutions in the embodiments of this utility model are clearly and completely described below. Obviously, the described embodiments are only some preferred embodiments of this utility model, and not all embodiments. Those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0031] An improved automatic wrapping device for insulating tape on bare wires (e.g.) Figure 1As shown, the device includes a fixed housing 1, a surrounding plate 2, a surrounding drive mechanism, and a controller. A first inlet 11 and a first bare wire slot 12 are sequentially arranged from top to bottom on the upper part of the fixed housing 1. The first inlet 11 and the first bare wire slot 12 are vertically connected. The internal width of the first inlet 11 and the first bare wire slot 12 can be adapted to the actual outer diameter of the bare wire, so that the bare wire can be smoothly inserted into the first inlet 11 and the first bare wire slot 12. Simultaneously, the gap between the bare wire and the first bare wire slot 12 in the left-right direction is minimized to ensure that the surrounding plate 2 can subsequently rotate stably around the bare wire. Plate 2 is rotatably mounted on the front side of the fixed housing 1. The surrounding drive mechanism is used to drive the surrounding plate 2 to perform circular motion around the axis of the first bare wire slot 12. In this specific embodiment, the specific implementation method of the surrounding drive mechanism to realize the self-rotation of the surrounding plate 2 is exactly the same as the specific implementation method of the surrounding plate to realize rotation in Chinese invention patent with authorization announcement number CN115410777B (title: A bare wire tape winding device). Therefore, the specific implementation method of the surrounding drive mechanism to realize the rotation drive of the surrounding plate 2 on the fixed housing 1 will not be described in detail here. The controller can realize the operation of the surrounding drive mechanism. For ease of high-altitude operations, ground personnel can use a remote control to send control commands to the controller. This allows ground personnel to control the device's workflow according to the actual working conditions. In actual control, the remote control primarily sends control commands to the surround drive mechanism to control the forward, reverse, and stop rotation of the surround plate 2. A first U-shaped slot 3, corresponding to the first inlet 11 and the first bare wire slot 12, is provided on the upper part of the surround plate 2. During actual operation, the bare wire is simultaneously secured within the first U-shaped slot 3. A third slot is provided on the lower part of the surround plate 2. A tape mounting seat 4 is located below the first U-shaped slot 3. The tape mounting seat 4 can rotate freely relative to the surrounding plate 2 and is used to install the tape roll. A tape pressing mechanism 5 is provided on the right side of the first U-shaped slot 3. The tape pressing mechanism 5 can press the tape wrapped on the bare wire. A tape cutting device 6 is provided at the upper left end of the first U-shaped slot 3. The tape cutting device is used to assist in cutting the tape. A resistance adjusting mechanism 7 is provided on one side of the tape mounting seat 4. The resistance adjusting mechanism 7 is used to adjust the resistance encountered by the tape mounting seat 4 during rotation.During the tape wrapping process on bare conductors using this invention, the tape pressing mechanism 5 can re-press the tape adhering to the bare conductor, thereby achieving a tight fit between the tape and the bare conductor. After the tape wrapping is completed, the tape cutting device 6 can be used to cut the tape. After the tape is cut, the pressing action of the tape pressing mechanism 5 can be used again to stick the end of the tape to the bare conductor, improving the aesthetics of the tape wrapping. At the same time, manual wrapping of the tape end on the bare conductor is not required, which also helps to improve the efficiency of tape wrapping on bare conductors. The resistance adjustment mechanism 7 can control the resistance encountered by the tape mounting base 4 during rotation. A large rotational resistance of the tape mounting base 4 results in a large rotational resistance of the tape roll that rotates synchronously with it. A large rotational resistance of the tape roll keeps the tape in a tensioned state during continuous tape output. Maintaining the tensioned state of the tape helps to achieve a tight fit between the tape and the side wall of the bare conductor.

[0032] Based on the above embodiments, the specific implementation of the tape pressing mechanism is as follows: The tape pressing mechanism 5 includes a first locking rod 51, a first spring 52, a pressure tongue 53, and a first tension spring 54. A first trapezoidal through-hole 31 is provided on the bottom side wall of the first U-shaped groove 3, and a second through-hole 32 is provided on the right side wall of the first U-shaped groove 3. The lower middle part of the first locking rod 51 is hinged to the outer bottom of the first U-shaped groove 3. The first spring 52 is engaged between the outer bottom of the first U-shaped groove 3 and the upper side wall of the right end rod 512 of the first locking rod 51. Under the push of a spring 52, the left end rod 511 of the first locking rod 51 can be stably locked in the first trapezoidal through-hole 31, and the upper arc-shaped surface of the left end rod 511 of the first locking rod 51 is higher than the bottom arc-shaped surface of the first U-shaped slot 3. In actual application, when the bare wire is pressed against the bottom of the first U-shaped slot 3, the left end rod 511 can be pushed into the first trapezoidal through-hole 31. The lower middle part of the pressure tongue 53 is hinged to the lower right side of the first U-shaped slot 3, and the upper part of the pressure tongue 53 is sleeved in the second through-hole 32. A latch 531 is provided at the lower middle position of part 3. The right end of the first locking rod 512 is engaged in the latch 531 under the push of the first spring 52. The upper part of the first tension spring 54 is fixedly connected to the surrounding plate 2, and the lower part of the first tension spring 54 is connected to the lower outer side of the pressure tongue 53. The first tension spring 54 is always in a stretched state. In actual application, when the bare wire is inserted into the bottom of the first U-shaped slot 3, the left end rod 511 can be pushed back into the first trapezoidal through-hole 31. The swinging motion of the left end rod 511 causes the right end rod 512 to rotate upward. When the right end rod 512 rotates upward, the right end of the right end rod 512 releases the pressure on the lower right part of the pressure tongue 53. After the pressure on the right end of the pressure tongue 53 is released, the upper part of the pressure tongue 53 rotates into the first U-shaped slot 3 under the pull of the first tension spring 54. The rotation of the upper part of the pressure tongue 53 realizes its pressure on the side wall of the bare conductor. When the tape is clamped between the side wall of the bare conductor and the upper part of the pressure tongue 53, the upper part of the pressure tongue 53 realizes the pressure of the tape. During the continuous rotation of the surrounding plate 2, the pressure tongue 53 is driven to rotate around the bare conductor, thereby realizing the circumferential pressure of the tape on the bare conductor.After the tape wrapping is completed and the bare wire is disengaged from the first U-shaped slot 3, the pressing action of the left end rod 511 is released. Once the left end rod 511 is freed from the pressure of the bare wire, it returns to its initial working position under the pushing action of the first spring 52. Simultaneously, as the first spring 52 pushes the left end rod 511 back to its initial position, the right end rod 512 swings downwards under the action of the first spring 52. During this swing, its right end engages in the latch 531. The pushing action of the right end rod 512 on the pressure tongue 53 causes the upper end of the pressure tongue 53 to swing to the right, thus returning the pressure tongue 53 to its initial working position. The return of the pressure tongue 53 to its initial position releases its tight contact with the bare wire.

[0033] Based on the above embodiment, when the tape is pressed against the upper part of the pressure tongue 53, in order to reduce the friction between the upper part of the pressure tongue 53 and the tape, a plurality of freely rotatable tape rolling rollers 531 are provided on the upper part of the pressure tongue 53.

[0034] Based on the above embodiments, the specific implementation of the tape cutting device 6 is as follows: The tape cutting device 6 includes a second locking rod 61, a second spring 62, a first torsion spring 63, a serrated cutting blade 64, a rotating seat 65, and an unlocking plate 66. A cutting fixing seat 22 is provided on the upper left side of the first U-shaped slot 3, and a tape inlet 21 is provided between the cutting fixing seat 65 and the upper left side of the first U-shaped slot 3. In actual application, the tape output from the tape roll on the tape mounting seat 4 is pulled out from the tape inlet 21. Before starting the tape winding, in order to facilitate the pulling out of the tape inlet 21... The free end of the tape is fixed. Here, a tape-hanging saw tooth can be set on the upper left side of the pressure tongue 53. When the tape is pressed forcefully onto the tape-hanging saw tooth, the saw tooth on the tape-hanging saw tooth temporarily fixes the free end of the tape. The rotating seat 65 is hinged to the left side of the cutting fixing seat 22 via a support shaft 651. The rotating seat 65 can rotate towards the tape inlet 21. The first torsion spring 63 is sleeved on the support shaft 652 and the first torsion spring 63 always applies a downward swinging torque to the rotating seat 65. An arc-shaped groove is set on the upper left side of the surrounding plate 2. The second locking rod 61 slides. The second spring 62 is fitted into the arc-shaped groove and is used to push the second locking rod 61 to slide to the left. A locking groove 611 is provided on the front right side of the second locking rod 61. A limiting block 651 adapted to the locking groove 611 is provided on the rear left side of the rotating seat 65. When the limiting block 651 is engaged in the locking groove 611, the initial positioning of the rotating seat 65 is achieved. In actual application, the height difference between the second locking rod 61 and the support shaft 651 is not large, so that when the limiting block 651 is engaged in the groove, the initial positioning of the rotating seat 65 is achieved. After the second locking rod 61 is positioned in the slot 611 on the initial locking rod 61, the rotating seat 65 can be positioned by swinging upwards. The serrated cutting blade 64 is fixedly installed on the left end of the rotating seat 65. When the rotating seat 65 is positioned, the serrated cutting blade 64 is also initially positioned. The unlocking plate 66 is fixedly installed on the upper left side of the fixed housing 1. A spring steel ball positioning plunger 612 is fixedly installed in the left end area of ​​the second locking rod 61. The spring steel ball positioning plunger 612 is a known mature technology product in the existing technical field. Therefore, the specific structure of the spring steel ball positioning plunger 612 will not be described in detail here.The steel ball 6121 of the spring steel ball positioning plunger 612 faces the fixed housing 1. When the surrounding plate 2 rotates clockwise, the unlocking plate 66 can push the steel ball 6121 in the spring steel ball positioning plunger 612 to retract. After the steel ball 6121 retracts, the unlocking plate 66 cannot move the second locking rod 61 to the right, and thus cannot release the rotation lock of the second locking rod 61 on the rotating seat 65. As a result, the serrated cutter 64 cannot cut the tape. Therefore, during the continuous clockwise rotation of the surrounding plate 2, the tape can be continuously wrapped around the bare wire.When the surrounding plate 2 rotates counterclockwise, the unlocking plate 66 can block the steel ball 6121 of the spring steel ball positioning plunger 612. Specifically, when it is necessary to end the wrapping of the tape on the bare wire, the surrounding plate 2 is first stopped rotating, and then the surrounding plate 2 is rotated counterclockwise. During the continuous counterclockwise rotation of the surrounding plate 2, when the steel ball 6121 of the spring steel ball positioning plunger 612 is blocked by the unlocking plate 66 and cannot continue to rotate counterclockwise, the surrounding plate 2 continues to rotate. Rotating counterclockwise causes the second locking lever 61 to move to the right relative to the surrounding plate 2. This rightward movement of the second locking lever 61 disengages the limiting block 651 from the locking groove 611. After the limiting block 651 disengages from the locking groove 611, the rotating seat 65 swings downward under the push of the first torsion spring 63, thereby enabling the serrated cutter 64 to cut the tape. When the serrated cutter 64 swings to the cutting position, the surrounding plate 2 stops rotating counterclockwise. When the serrated cutter 64 is in the cutting position... When the cutting position is reached, it cannot completely cut the tape. Therefore, after the surrounding plate 2 stops rotating counterclockwise, it is restarted to rotate clockwise again (the clockwise rotation of the surrounding plate 2 causes the second locking rod 61 to return to its initial position under the push of the second spring 62). When the surrounding plate 2 rotates clockwise again, the bare wire exerts a certain tension on the tape. Because the tape connection strength of the serrated cutter 64 is very weak, it breaks after being subjected to a certain tension, thus achieving tape cutting. After the tape is cut, the wrapping plate 2 continues to rotate clockwise around the bare wire several times. During the clockwise rotation of the wrapping plate 2, the upper part of the pressure tongue 53 still exerts pressure on the tape, which allows the end of the tape to also be tightly attached to the bare wire under the pressure of the pressure tongue 53, thereby improving the aesthetics of the tape wrapping. After the tape wrapping is completed, when the opening of the first U-shaped slot 3 is facing upward, the rotation of the wrapping plate 2 is stopped, which makes it easier to remove the entire fixed housing 1 from the bare wire. When performing the next tape wrapping operation, the rotating seat 65 needs to return to its initial position. In this specific embodiment, the rotating seat 65 is manually pushed counterclockwise back to its initial working position. When the limiting block 651 is once again engaged in the positioning groove 611, the rotating seat 65 is positioned, thereby positioning the serrated cutter 64. To facilitate the smooth sliding of the limiting block 651 into the positioning groove 611 during the counterclockwise rotation of the rotating seat 65, a first guide slope 6111 is provided at the lower part of the positioning groove 611, and a second guide slope 6511 corresponding to the first guide slope 6111 is provided at the lower part of the limiting block 651.

[0035] During the clockwise rotation of the surrounding plate 2, in order to effectively prevent the unlocking plate 66 from pushing the steel ball 6121 and thus pushing the second locking rod 61, a steel ball retraction guide slope 661 is provided on the lower left side of the unlocking plate 66.

[0036] Based on the above embodiments, the specific implementation of the resistance adjustment mechanism is as follows: The resistance adjustment mechanism 7 includes a pressure plate 71, a fixed seat 72, and a top-pressing bolt 73. A pressure plate slot is provided on the annular plate 2 on one side of the rotating drum 41 of the tape mounting seat 4. The pressure plate 71 is made of elastic metal material and is locked in the pressure plate slot. The lower right end of the pressure plate 71 can move freely in the pressure plate slot. The fixed seat 72 is provided on the annular plate 2, and the top-pressing bolt 73 is provided on the fixed seat 72. By rotating the top-pressing bolt 73, the lower right end of the pressure plate 71 can be pressed against the side wall of the rotating drum 41. When the top pressure of the top-pressing bolt 73 on the pressure plate 71 is relatively high... When the pressure is large, the rotational resistance of the drum 41 is relatively large. When the pressure of the top bolt 73 on the pressure plate 71 is small, the rotational resistance of the drum 41 is relatively small. In practical applications, a pressure cap 411 is set at the front of the drum 41. The pressure cap 411 and the drum 41 are connected by a threaded connection. After the tape roll is placed on the drum 41, the pressure cap 411 is used to fix the tape roll on the drum 41 so that the tape roll can rotate synchronously with the drum 41. Then, the pressure plate 71 is used to adjust the rotational resistance of the drum 41, and finally the rotational resistance of the tape roll is adjusted. When the tape roll is obstructed during rotation, the tape output is kept in a tensioned state. The tension of the tape is conducive to the tight adhesion between the tape and the bare wire.

[0037] In practical applications, when using insulating tape with an outer film for insulation protection of bare wires, in order to facilitate the automated collection of the outer film, an outer film collection assembly is also provided on the surrounding plate 2, located to the left of the first U-shaped locking groove 3. The outer film collection assembly 8 includes a cylindrical support base, a spring, and a winding cylinder 81. The cylindrical support base is disposed on the surrounding plate 2, the spring is sleeved inside the cylindrical support base, and the outer end of the spring is fixedly locked on the side wall of the cylindrical support base. The winding cylinder 81 is rotatably sleeved on the cylindrical support base, and a synchronous drive shaft is fixedly disposed in the middle of the winding cylinder 81. The inner end of the spring is fixedly locked on the synchronous drive shaft. In practical applications, before the tape needs to be wound, the winding drum 81 is rotated to make the spring retract. Then, the winding drum 81 is kept stationary, and the free end of the tape roll is pulled to the position of the winding drum 81, so that the outer film of the tape is wound around the winding drum 81 several times. Then, the rotation limit of the winding drum 81 is released. As the tape is continuously output, the winding drum 81 can also automatically wind the outer film under the drive of the spring, thereby realizing the automatic collection of the outer film. Furthermore, in order to facilitate the smooth retraction and rotation of the spring using the winding drum 81, a handle 811 is provided on the front side of the winding drum 81.

[0038] In this utility model, "front", "rear", "up", "down", "left" and "right" are relative positions used for the convenience of describing positional relationships, and therefore cannot be understood as absolute positions as a limitation on the scope of protection.

[0039] Except for the technical features described in the specification, all other technologies are known to those skilled in the art.

[0040] The preferred embodiments and examples of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments and examples. For those skilled in the art, several improvements and modifications can be made without departing from the concept of the present invention, and these improvements and modifications should also be considered within the protection scope of the present invention.
