Abstract
Description
Technical Field
[0001] The utility model relates to the field of film-wrapped wire production, in particular to a film-wrapped sleeve for film-wrapped wires. Background Art
[0002] Film-covered wire, also known as Mylar wire, is an electromagnetic wire with a synthetic film or other material film coated on the surface of the conductor or enameled twisted wire at a certain overlapping rate as an insulating layer. This increases the insulation voltage of the wire and also serves as a shield, which can replace silk-covered wire.
[0003] When the film-wrapped wire is being coated, the coating tape will rotate around the conductor, so that the coating tape is wrapped around the conductor. The coating tape will inevitably shake when it is quickly rotated and wrapped around the conductor. Long-term shaking will cause the position of the coating tape to shift, resulting in changes in the interval of the tape wrapped around the conductor, thereby affecting the insulation performance of the conductor and being detrimental to the use of the conductor.

[0027] Reference Figure 1-4The utility model provides a coating sleeve for film-wrapped wires: comprising a sleeve mechanism 1, on which a winding mechanism 2 is installed, which is convenient for winding the coating tape onto the wire, the sleeve mechanism 1 comprises a front tube 101, when in use, the wire passes through the front tube 101 to the left side of the front tube 101 for coating winding, the outer surface of the front tube 101 is provided with a connecting groove 102, the outer surface of the front tube 101 is provided with a mounting groove 103, an electrode sheet 104 is installed inside the mounting groove 103, the electrode sheet 104 can be disassembled in the mounting groove 103, and the electrode sheet 104 can be disassembled in the mounting groove 103. The electrode sheet 104 can be replaced after being worn. The left end of the electrode sheet 104 is located inside the connecting groove 102. The winding mechanism 2 includes a rotating frame 201. The right side of the rotating frame 201 is fixedly connected to a connecting rod 202. The end of the connecting rod 202 away from the rotating frame 201 is fixedly connected to a metal plate 203. The metal plate 203 is installed inside the connecting groove 102, and the right side of the metal plate 203 is in contact with the left end of the electrode sheet 104. The metal plate 203 will contact the electrode sheet 104 for each rotation in the connecting groove 102. Next, the lower surface of the rotating frame 201 is fixedly connected with a mounting frame 204. When in use, the coating tape is installed on the mounting frame 204 to wrap the wire, and then the device is started (the main function of the device is to drive the rotating frame 201 to rotate around the sleeve mechanism 1, which is not drawn in the figure). The rotating frame 201 is driven by the device to rotate, so that the tape is wrapped around the wire and the wire is coated. When the rotating frame 201 rotates, the metal plate 203 also rotates in the connecting groove 102. When the metal plate 203 rotates to the position of the electrode sheet 104, the electrode sheet 104 will be The positive and negative electrodes on 104 are connected, and the circuit is connected at this time. Current can be detected from the wire 105, so as to judge that the metal plate 203 is inside the connecting groove. If the circuit is not connected for a long time and current cannot be detected at the wire 105, it is judged that the metal plate 203 is not inside the connecting groove 102, indicating that the metal plate 203 is out of the connecting groove 102, and the position of the coating tape and the conductor is deviated. At this time, the staff can calibrate the position of the coating tape so that the tape can be better wrapped around the surface of the conductor, which is convenient for the production and processing of the film-coated wire.
[0028] An electric wire 105 is fixedly connected to the outer surface of the front tube 101, and one end of the electric wire 105 is electrically connected to the right end of the electrode sheet 104. There are two electric wires 105, and the electrode sheet 104 has two terminal posts, positive and negative, and the two terminal posts do not touch. When in use, one electric wire 105 is energized and detection is performed at the other electric wire 105. In a normal state, the two terminal posts do not touch and the circuit is in an open circuit state, and no current can be detected at the other electric wire 105. When the metal plate 203 reaches the electrode sheet 104, the two terminal posts are in contact with the metal plate 203, and the circuit is connected. At this time, current can be detected at the other electric wire 105, so as to determine whether there is an offset between the coating tape and the conductor.
[0029] The right end of the front tube 101 is fixedly connected to the rear tube 107. The front tube 101 is a circular pipe, and the rear tube 107 is a square structure. A first channel 106 is opened inside the front tube 101, and a second channel 108 is opened inside the rear tube 107. The first channel 106 is connected to the second channel 108. When in use, the wire is passed through the second channel 108 and the first channel 106 in turn to reach the left side of the front tube 101 for wrapping.
[0030] A limiting groove 109 is provided on the surface of the rear tube 107. There are two limiting grooves 109, which are respectively located on the upper and lower sides of the rear tube 107. A rotating shaft 110 is fixedly connected inside the limiting groove 109. There are multiple rotating shafts 110, and rollers 111 are movably connected to the outer surfaces of the multiple rotating shafts 110. The multiple rollers 111 inside the limiting groove 109 can limit the wire inside the second channel 108, so that the wire can remain stable when moving in the channel, reducing jitter, making it easier for the coating tape to be evenly wrapped around the surface of the wire, and facilitating the production and processing of the film-coated wire.
[0031] Working principle: When in use, pass the wire through the first channel 106 and the second channel 108, and install the coating tape on the mounting frame 204 to wrap the wire, then start the equipment, and drive the rotating frame 201 to rotate through the equipment, so as to wrap the tape around the wire and coat the wire. When the rotating frame 201 rotates, the metal plate 203 also rotates in the connecting groove 102. When the metal plate 203 rotates to the position of the electrode sheet 104, the positive and negative electrodes on the electrode sheet 104 will be connected. At this time, the circuit is connected, and the current can be detected from the wire 105, so as to judge that the metal plate 203 is inside the connecting groove. If the circuit is not connected for a long time and the current cannot be detected at the wire 105, it is judged that the metal plate 203 is not inside the connecting groove 102, indicating that the metal plate 203 is out of the connecting groove 102, and the position of the coating tape and the wire deviates. At this time, the staff can calibrate the position of the coating tape so that the tape can be better wrapped around the surface of the wire, which is convenient for the production and processing of the film-coated wire.
