They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0024] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0025] like Figure 1-4As shown, the core 7 coating device of this utility model includes a support frame 1. A left support 21 and a right support 25 are mounted on the support frame 1 via a sliding device. The sliding device consists of two corresponding slide rails 61 and sliders 62 mounted on the support frame 1. The slide rails 61 are fixedly mounted on the support frame 1, and the sliders 62 are slidably mounted on the slide rails 61. The left support 21 and the right support 25 can move towards each other via the sliding device. A left clamp 23 is mounted on the left support 21 via a first rotating shaft 22, and a right clamp 27 is mounted on the right support 25 via a second rotating shaft 24. The right clamp 27 and the left clamp 23 are correspondingly arranged, and the right clamp 27 and the left clamp 23 can rotate on the left support 21 and the right support 25 via the first rotating shaft 22 and the second rotating shaft 24.

[0026] On the right side of the right bracket 25, a motor bracket 26 is also installed to cooperate with the right bracket 25. A magnetic powder motor 4 is installed on the motor bracket 26. The rotating shaft of the magnetic powder motor 4 is connected to the second rotating shaft 24 for transmission. The magnetic powder motor 4 is powered by an external power supply and is used to drive the rotation of the second rotating shaft 24.

[0027] An adjusting device 3 is mounted on the bottom of each of the left and right supports 25 via a connecting block 5. The adjusting device 3 is used to adjust the distance between the left and right supports 21 and 25. The adjusting device 3 includes a lead screw 31, a bearing seat 32, a nut 33, and a handwheel 34. The lead screw 31 is mounted on the support frame 1 below the sliding device via the bearing seat 32. The nut 33 is correspondingly positioned to the bearing seat 32 and is fixedly mounted below the connecting block 5. The front end of the lead screw 31 passes through the nut 33 and is threaded into it. The handwheel 34 is fixedly mounted on the end of the lead screw 31 outside the bearing seat 32. By rotating the handwheel 34 on each of the two adjusting devices 3, the lead screw 31 rotates, causing the connecting block 5 with the nut 33 to move the left and right supports 21 and 25 on the slide rail 61.

[0028] A load-bearing frame 12 is fixedly connected to the support frame 1 in front of the support frame 1 at the sliding device. The load-bearing frame 12 is provided with two corresponding rolling seats. The rolling seats include two corresponding support plates 121. The middle part of the two support plates 121 is provided with an arc-shaped groove. The edge of the arc-shaped groove is provided with two cooperating rollers 122. The rollers 122 are rotatably mounted on the two support plates 121. The film roll is placed on the two support plates 121, and the rollers 122 allow the film roll to rotate freely on the support plates 121.

[0029] The lower part of the support frame 1 is also fixedly installed with a storage rack 11 extending forward of the support frame 1. The front part of the storage rack 11 is provided with two corresponding stops 111, which can prevent the film roll placed on the storage rack 11 from slipping off. In addition, two casters 10 are installed at the bottom of the support frame 1 and two casters 10 are also installed at the bottom of the storage rack 11 to facilitate the movement of the film coating device of the core 7.

[0030] When using the core 7 coating device, firstly, by rotating the handwheel 34, the right clamp 27 and the left clamp 23 are moved away from each other until the core 7 can be placed between them. When the core 7 is placed between the right clamp 27 and the left clamp 23, the handwheel 34 is rotated to move the right clamp 27 and the left clamp 23 closer together and insert them into the core 7 to fix it. Then, the operator pulls the film guide on the support plate 121 and attaches it to the core 7 with tape. Then, the magnetic powder motor 4 is started to pull the film guide and wrap it around the core 7. After wrapping, the right clamp 27 and the left clamp 23 are moved away from each other by rotating the handwheel 34, and the coated core 7 is removed. Then, the next operation can be carried out.

[0031] It should be noted that the film winding time is relatively short. During the film winding process on the core 7, the staff needs to observe the flatness of the film winding in a timely manner. Therefore, when operating the magnetic powder motor 4 to wind the film, the staff will control the handwheel 34 to prevent the lead screw 31 from rotating during the film winding process.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
