Abstract
Description
Technical Field
[0001] This utility model relates to the field of insulating tape processing technology, specifically to an insulating tape coating device. Background Technology
[0002] A utility model with application number 201920682084.X discloses a coating equipment for high-insulation nanocrystalline magnetic core strips. The equipment includes a worktable with a longitudinal space for accommodating a coating device. A strip receiving device and a strip releasing device are respectively installed at both ends of the worktable along its length. Strip rolls are fitted onto the receiving and releasing devices. A circulating coating device and a drying device are also installed between the receiving and releasing devices. The strip is drawn from the roll on the releasing device, passes through the circulating coating and drying devices, and is then rewound onto the receiving device. The strip rolls on both the releasing and receiving devices are oriented vertically. After being drawn out, the surface of the strip always faces the side, meaning the strip moves vertically. The circulating coating device includes an outlet tap with a corresponding receiving hopper at its lower part. This device improves the coating effect, enhances the insulation of the nanocrystalline magnetic core, and effectively reduces eddy current losses.
[0003] However, in the above-mentioned insulating tape coating device, during the material receiving and discharging processes, the discharging device lacks a driving mechanism and a limiting mechanism, making the insulating tape roll on the discharging device prone to loosening. This causes the tension of the tape to be unstable during the conveying process, resulting in uneven tape coating and affecting the coating effect of the tape. Utility Model Content
[0004] To address the problem that some existing insulating tape coating devices suffer from uneven coating and poor coating results during the feeding and unloading processes due to the lack of a driving and limiting mechanism in the unloading device, which leads to loosening of the insulating tape rolls and unstable tension during transport, the present invention aims to provide an insulating tape coating device.
[0005] To solve the above technical problems, the present invention adopts the following technical solution: an insulating tape coating device, comprising a worktable, on which an unwinding reel and a winding reel are rotatably mounted, and an air shaft is fixedly mounted at the center of the upper surface of both the unwinding reel and the winding reel.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0020] Example: Figure 1-6As shown, this utility model provides an insulating tape coating device, including a worktable 1. An unwinding reel 2 and a take-up reel 3 are rotatably mounted on the worktable 1. An air shaft 4 is fixedly installed at the center of the upper surface of both the unwinding reel 2 and the take-up reel 3. The air shaft 4 is existing technology and mainly consists of a shaft core, a pneumatic key, and an air nozzle. The shaft core is typically made of metal (such as steel or aluminum alloy) and has an internal air chamber and air passage. After inflation, it expands, pushing the external pneumatic key to bulge and clamp the roll material. It is connected to an air pump via the air nozzle for inflation / deflation. The upper surface of the worktable 1... A coating box 6 is fixedly installed, and a coating device and a drying device are installed inside the coating box 6. For details on the specific coating and drying structures and working principles, please refer to the patent document with application number 201920682084.X, which will not be repeated here. A cleaning component 7 is detachably installed at one end of the coating box 6 near the unwinding reel 2. A drive shaft 11 is rotatably mounted on the lower surface of the worktable 1. Two symmetrically distributed first bevel gears 9 are fixedly mounted on the drive shaft 11. Second bevel gears 12 are fixedly mounted at the bottom ends of the rotating shafts of both the unwinding reel 2 and the take-up reel 3. The second bevel gear 12 meshes with the corresponding first bevel gear 9. A drive motor 10 is fixedly installed at one end of the worktable 1, and the output end of the drive motor 10 is fixedly connected to one end of the drive shaft 11. The insulating tape roll to be coated can be placed on the unwinding reel 2, and the winding drum for winding can be placed on the air shaft 4 on the winding reel 3 and fixed using the air shaft 4. Then, one end of the insulating tape roll is pulled through the cleaning component 7 and the coating box 6. The cleaning component 7 can clean the surface of the tape, and the tape will be placed in the coating box 6. The insulating tape is coated and dried using a coating and drying device. Then, it is wound onto a take-up drum and tightened. Next, the air shaft 4 on the unwinding reel 2 is used to fix the insulating tape roll. The drive motor 10 drives the drive shaft 11 to drive the two first bevel gears 9 to rotate synchronously in the same direction. The two first bevel gears 9 mesh with the corresponding second bevel gears 12, driving the unwinding reel 2 and the take-up reel 3 to rotate synchronously in the same direction, so that the tension of the insulating tape remains stable during the conveying process, and the tape can be coated evenly.
[0021] The cleaning component 7 includes a mounting frame 701. Each end of one side of the mounting frame 701 is fixedly fitted with a clip 702. Each end of the coating box 6 has slots 601 on both sides, and the clips 702 on the mounting frame 701 can slide into the corresponding slots 601. Two mirror-distributed sliding plates 703 are slidably mounted inside the mounting frame 701. Cleaning cloths 704 are attached to the sides of the two sliding plates 703 that are close to each other via Velcro. Spring telescopic rods 705 are fixedly mounted on both sides inside the mounting frame 701, and one end of each spring telescopic rod 705 is fixedly connected to the corresponding sliding plate 703. The spring force of the spring telescopic rods 705 causes the two sliding plates 703 with attached cleaning cloths 704 to move closer together, clamping the strip. This allows the cleaning cloths 704 to clean the surface of the strip during movement, facilitating subsequent coating. The cleaning cloths 704 are attached to the sliding plates 703 via Velcro, making them easy to replace.
[0022] A limiting component 8 is installed on the coating box 6. The limiting component 8 includes a fixing groove 801, which is fixedly installed on the top of the coating box 6. A limiting rod 802 is slidably installed in the fixing groove 801. A lever 805 is fixedly installed on one end of the limiting rod 802. A compression spring 804 is fixedly installed in the fixing groove 801, and one end of the compression spring 804 is fixedly connected to one end of the limiting rod 802. A limiting frame 803 is fixedly installed on the top of the mounting frame 701, and one end of the limiting rod 802 can be inserted into the limiting frame 803. This allows the mounting frame 701 to be limited. When it is necessary to disassemble the cleaning component 7, the lever 805 can be used to drive the limiting rod 802 to slide and retract into the fixing groove 801, and squeeze the compression spring 804, thereby releasing the limitation on the mounting frame 701 and allowing the cleaning component 7 to be removed.
[0023] Guide components 5 are installed on the upper surface of the worktable 1 near the unwinding reel 2 and the rewinding reel 3. Each guide component 5 includes a slide groove 501, which is fixedly installed on the upper surface of the worktable 1. Two symmetrically distributed sliders 502 are slidably installed in each of the two slide grooves 501. Rotating rollers 503 are rotatably installed on the top of each of the four sliders 502. Bidirectional lead screws 504 are rotatably installed in each of the two slide grooves 501, and the bidirectional lead screws 504 are threaded into the corresponding two sliders 502. Both guide components 5 are located on the central axis of the coating box 6, which facilitates the centered conveying of the strip. The strip can pass between the corresponding two rotating rollers 503. According to the thickness of the strip, the bidirectional lead screws 504 drive the corresponding two sliders 502 and the rotating rollers 503 to slide towards each other, thereby limiting and guiding the strip.
[0024] Working Principle: In use, the insulating tape roll to be coated is placed on the unwinding reel 2, and the winding drum is placed on the air shaft 4 on the winding reel 3 and fixed using the air shaft 4. Then, one end of the insulating tape roll is pulled through between the two corresponding rotating rollers 503. Depending on the thickness of the tape, the two corresponding sliders 502 and the rotating rollers 503 are driven to slide towards each other by the bidirectional lead screw 504, limiting and guiding the tape. The tape then passes between the two sliding plates 703 of the cleaning component 7. The two sliding plates 703 with cleaning cloth 704 attached are brought closer together by the elastic force of the spring telescopic rod 705, clamping the tape. As the tape moves, the surface of the tape is cleaned with a cleaning cloth 704. The tape passes through the coating box 6, where it is coated and dried by the coating and drying devices. The tape is then wound onto the take-up drum and tightened. The air shaft 4 on the unwinding reel 2 is used to fix the insulating tape roll. The drive motor 10 drives the drive shaft 11 to drive the two first bevel gears 9 to rotate synchronously in the same direction. The two first bevel gears 9 mesh with the corresponding second bevel gears 12, driving the unwinding reel 2 and the take-up reel 3 to rotate synchronously in the same direction, thus keeping the tension of the insulating tape stable during the conveying process and enabling the tape to be coated evenly.
