[0059] In order to prevent the mica tape roll 3 from falling off the turntable 2 due to the damage of the connecting rotating shaft during high-speed rotation, a protective structure for preventing the mica tape roll 3 from being thrown out during rotation is arranged on one side of the mica tape coater 1. The protective structure includes a limiting structure for improving the installation stability of the mica tape roll 3 and a supporting structure for providing support for the installation of the mica tape roll 3.

[0060] Among them, the limiting structure includes a support frame 4 arranged on one side of the turntable 2, mounting holes 401 opened on the inner walls of the support frame 4 and the turntable 2, a mounting shaft 402 movably installed in the mounting holes 401, a nut 403 threadedly installed on the mounting shaft 402.

The mica tape roll 3 is located inside the support frame 4. The nut 403 is in contact with one side of the turntable 2. The mica tape roll 3 is placed inside the support frame 4, and then the mica tape roll 3 is pressed. When the holes on the mica tape roll 3 correspond to the mounting holes 401 on the support frame 4, the mounting shaft 402 can be passed through the mounting holes 401, the mica tape roll 3 and the turntable 2, and then the nut 403 is screwed on to fix the position of the mounting shaft 402.

[0061] Among them, the supporting structure includes a movable plate 5 slidably installed on the inner wall of the support frame 4, a supporting plate 501 arranged on one side of the movable plate 5, a supporting roller 502 rotatably installed on the supporting plate 501 and in contact with the mica tape roll 3 to provide support for the mica tape roll 3, and a friction assembly arranged on the movable plate 5 and in contact with the mica tape roll 3 to increase the resistance when the mica tape roll 3 rotates. The mica tape roll 3 can rotate on the mounting shaft 402, and at the same time, the rotating mica tape roll 3 can drive the supporting roller 502 to rotate.

[0062] Specifically, the friction assembly includes a friction block 503 arranged on one side of the movable plate 5 and in contact with the mica tape roll 3. Friction can be generated between the mica tape roll 3 and the friction block 503 during rotation, and the resistance generated when the mica tape roll 3 rotates can be increased by setting the friction block 503.

[0063] Among them, an adjusting component is further arranged on the supporting structure. The adjusting component includes a guiding slider 504 that is slidably installed on the inner wall of the supporting frame 4 and is arranged on one side of the movable plate 5 to guide the movement of the movable plate 5, an auxiliary spring 505 whose two ends are respectively arranged on the guiding slider 504 and the supporting frame 4 to reset the movement of the guiding slider 504, a guiding rod 506 arranged on the inner wall of the supporting frame 4, the guiding rod 506 is slidably installed on the guiding slider 504 to prevent the guiding slider 504 from loosening, the auxiliary spring 505 is sleeved on the guiding rod 506. Press the mica tape roll 3, so that the mica tape roll 3 presses the supporting roller 502 and drives the supporting plate 501 to move. The moving supporting plate 501 will drive the movable plate 5 to move. When the movable plate 5 moves, it can drive the guiding slider 504 to slide on the guiding rod 506 and compress the auxiliary spring 505.

[0064] Embodiment 2:

[0065] On the basis of Embodiment 1, in order to be able to give a timely reminder to the staff when the mica tape on the mica tape roll 3 is used up, an adaptation structure for moving along with the change in the thickness of the mica tape on the mica tape roll 3 is arranged on the supporting structure, and an alarm structure for making a sound after the mica tape on the mica tape roll 3 is used up is arranged on the adaptation structure.

[0066] Among them, the adaptation structure includes an adaptation roller 6 that contacts the mica tape on the mica tape roll 3, a roller frame 601 rotatably installed on the adaptation roller 6 to support the adaptation roller 6, a limiting rod 602 arranged on one side of the roller frame 601, a movable seat 603 slidably installed on the limiting rod 602, a lead screw 604 threadedly installed on the movable seat 603, an adaptation spring 605 whose two ends are respectively arranged on the supporting plate 501 and the movable seat 603 to reset the movement of the movable seat 603, the adaptation spring 605 is slidably sleeved on the lead screw 604, a limiting rotating shaft 606 rotatably installed on the inner wall of the lead screw 604, the limiting rotating shaft 606 is arranged on one side of the roller frame 601, the limiting rod 602 is slidably installed on the supporting plate 501 to guide the movement of the roller frame 601, the lead screw 604 is slidably installed on the supporting plate 501. When the mica tape on the mica tape roll 3 gradually decreases with the use time, the stretched adaptation spring 605 will contract and pull the movable seat 603 to move and reset. The reset movable seat 603 will drive the lead screw 604 to move and reset, and the lead screw 604 will drive the roller frame 601 and the adaptation roller 6 to reset, so that the adaptation roller 6 continuously adheres to the mica tape on the mica tape roll 3, and further enables the adaptation roller 6 to move along with the change in the mica tape thickness.

[0067] Among them, the alarm structure includes an alarm 607 arranged on one side of the movable seat 603 for emitting an alarm sound, and an alarm switch 608 arranged on the alarm 607 for turning on the alarm 607. When the mica tape on the mica tape roll 3 is used up, the continuously reset movable seat 603 will drive the alarm switch 608 on the alarm 607 to squeeze against one side of the support plate 501, thereby triggering the alarm 607 to emit an alarm.

[0068] Working principle:

[0069] During installation, rotate the turntable 2 to place the support frame 4 at the bottom. Then, place the mica tape roll 3 into the support frame 4, making the mica tape roll 3 contact the support roller 502. After that, press the mica tape roll 3 so that the mica tape roll 3 squeezes the support roller 502 and drives the moving plate 5 to move. When the moving plate 5 moves, it can drive the guiding slider 504 to slide on the guiding rod 506 and compress the auxiliary spring 505. When the hole on the mica tape roll 3 corresponds to the mounting hole 401 on the support frame 4, the mounting shaft 402 can be passed through the mounting hole 401, the mica tape roll 3, and the turntable 2. Then, screw on the nut 403 to fix the position of the mounting shaft 402 and restrict the position of the mica tape roll 3 at the same time. When covering the mica tape on the cable core, the mica tape roll 3 can rotate on the mounting shaft 402. At the same time, the rotating mica tape roll 3 can drive the supporting roller 502 to rotate. During the rotation of the mica tape roll 3, friction can be generated between the mica tape roll 3 and the friction block 503. By setting the friction block 503, the resistance generated during the rotation of the mica tape roll 3 can be increased, making the mica tape in a taut state when being pulled out. Moreover, the moving position of the moving plate 5 can be adapted according to the size of the mica tape roll 3. And when installing the mica tape roll 3, the mica tape wound on the mica tape roll 3 will contact and squeeze the adapting roller 6. When the adapting roller 6 is squeezed, it will drive the roller frame 601 to move. The roller frame 601 will drive the two limiting rods 602 to slide on the moving plate 5, thereby restricting the moving direction of the roller frame 601. The continuously moving roller frame 601 will drive the lead screw 604 to slide, so that the lead screw 604 drives the moving seat 603 to move through the threaded cooperation with the moving seat 603. The moving seat 603 will stretch the adapting spring 605 and drive the alarm 607 to move. When the mica tape on the mica tape roll 3 gradually decreases with the use time, the stretched adapting spring 605 will contract and pull the moving seat 603 to move back to its original position. The reset moving seat 603 will drive the lead screw 604 to move back to its original position, and the lead screw 604 will drive the roller frame 601 and the adapting roller 6 to reset, making the adapting roller 6 continuously fit the mica tape on the mica tape roll 3. Thus, the adapting roller 6 can move with the change of the mica tape thickness. When the mica tape on the mica tape roll 3 is used up, the continuously reset moving seat 603 will drive the alarm switch 608 on the alarm 607 to press against one side of the moving plate 5, thereby triggering the alarm 607 and making the alarm 607 emit an alarm. And by rotating the lead screw 604, it can rotate on the limiting rotating shaft 606. During the rotation of the lead screw 604, it can drive the moving seat 603 to slide on the limiting rod 602 through the threaded cooperation with the moving seat 603, and the distance between the alarm 607 and the roller frame 601 can be adjusted. By adjusting the distance between the roller frame 601 and the alarm 607, the effect of adjusting the triggering distance of the alarm 607 can be achieved, so as to adjust according to the thickness of the mica tape wound on the mica tape roll 3.

[0070] Obviously, those skilled in the art can make various modifications and variations to the present utility model without departing from the spirit and scope of the present utility model. Thus, if these modifications and variations of the present utility model fall within the scope of the claims of the present utility model and their equivalent technologies, the present utility model is also intended to include these modifications and variations.
