Description

Technical Field

[0001] This utility model relates to the field of tape feeding machine technology, specifically a tape feeding machine for nanocrystalline ribbon. Background Technology

[0002] The nanocrystalline ribbon unloading machine is a key piece of equipment in the production process of nanocrystalline soft magnetic materials. It is mainly used to achieve stable and continuous release of nanocrystalline ribbons during production or processing. Due to their high magnetic permeability and low loss characteristics, nanocrystalline ribbons are widely used in electronic components, high-frequency transformers, and other fields. Their production or subsequent processing (such as winding and slitting) places stringent requirements on tension control and release stability. The unloading machine is a specialized device designed to meet these needs. In practical applications, the unloading machine needs to be adaptable to nanocrystalline ribbons of different specifications (such as differences in width and thickness) and to the efficient pace of continuous production. Because nanocrystalline ribbons are thin and sensitive to mechanical stress, the unloading process must avoid ribbon vibration, deviation, or tensile deformation, otherwise it may affect the accuracy of subsequent processing or material properties. The equipment usually needs to coordinate with other parts of the production line (such as winding devices and slitting equipment) to ensure that the ribbon release speed matches the requirements of subsequent processes, while maintaining dynamic tension balance to prevent ribbon breakage due to excessive tension or loose stacking due to insufficient tension. Furthermore, the tape unloading machine must adapt to environmental fluctuations (such as changes in temperature and humidity) within a certain range to reduce the interference of external factors on the stability of tape release. Its operational reliability directly affects the production efficiency and quality consistency of nanocrystalline tape, and is a crucial link in ensuring the stable performance of downstream products.

[0003] In actual production, nanocrystalline ribbon unloading machines have operational pain points: when changing ribbons, the positioning needs to be adjusted repeatedly, which takes a long time; the clamping mechanism has poor adaptability to ribbon specifications, and manual fine-tuning is often required to fix the new ribbon; the ribbon winding shaft locking device is cumbersome to operate and is prone to interference with surrounding parts when disassembled. Utility Model Content

[0004] The purpose of this invention is to provide a nanocrystalline ribbon feeding machine, which solves the problem that it is inconvenient to disassemble and replace nanocrystalline ribbons during use.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a nanocrystalline ribbon feeding machine, comprising a base, a fixed frame fixedly connected to the left side of the base, a connecting frame contacting the right side of the base, rollers contacting the interior of both the fixed frame and the connecting frame, a rotating shaft connected to the interior of the fixed frame and the connecting frame via bearings, a motor fixedly mounted on the left side of the fixed frame, a square block contacting the left side of the connecting frame, a threaded rod rotatably connected inside the connecting frame, the threaded rod being threadedly connected to the base, a retaining ring fixedly connected to the outer side of the threaded rod, a knob fixedly connected to the end of the threaded rod away from the base, the knob contacting the connecting frame, a guide rod fixedly connected to the side of the connecting frame near the base, a guide block fixedly connected to the outer side of the guide rod, the guide rod being slidably connected to the base, the guide block being slidably connected to the base, and a limit mechanism provided on the rollers.

[0006] Preferably, the output end of the motor is rotatably connected to the fixed frame, and the motor is fixedly connected to the rotating shaft. Through the design of the motor, the roller can be driven to rotate.

[0007] Preferably, the square block is fixedly connected to the rotating shaft and slidably connected to the roller. The design of the square block can provide support for the roller.

[0008] Preferably, the retaining ring is rotatably connected to the connecting frame and contacts the base. The design of the retaining ring can limit the movement of the threaded rod.

[0009] Preferably, a fixing rod is fixedly connected inside the base, and the fixing rod is slidably connected to the guide block. The design of the fixing rod can limit the movement of the guide block.

[0011] Preferably, one end of the spring contacts the slide rod, and the other end of the spring contacts the sleeve. By setting the spring, the top block can be driven to fit with the nanocrystalline ribbon.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model adds a connecting frame, a square block and a threaded rod assembly. Rotating the threaded rod drives it to engage with the base threadedly, causing the square block to slide out of the roller, quickly releasing the roller limit, and realizing convenient disassembly and replacement of nanocrystalline strip. This effectively solves the problem of time-consuming and laborious strip replacement caused by the fixed structure of traditional strip feeding machines, and improves operating efficiency.

[0014] 2. This utility model, by providing components such as a sliding rod, a top block, and a spring, allows the top block to limit the nanocrystalline ribbon when it is installed on the roller through the elastic force of the spring. This allows the roller to limit the placement of nanocrystalline ribbons with different inner diameters, ensuring that the nanocrystalline ribbon remains stable when installed on the roller.

[0020] 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.

[0021] Please see Figure 1-4A nanocrystalline ribbon feeding machine includes a base 1, a fixed frame 2 fixedly connected to the left side of the base 1, and a connecting frame 3 contacting the right side of the base 1. Rollers 4 are in contact inside both the fixed frame 2 and the connecting frame 3. A rotating shaft 41 is connected inside the fixed frame 2 and the connecting frame 3 through a bearing. A motor 42 is fixedly installed on the left side of the fixed frame 2. The output end of the motor 42 is rotatably connected to the fixed frame 2. The motor 42 is fixedly connected to the rotating shaft 41. Through the design of the motor 42, the rollers 4 can be driven to rotate. A square block 43 is contacting the left side of the connecting frame 3. The square block 43 is fixedly connected to the rotating shaft 41 and slidably connected to the rollers 4. Through the design of the square block 43, the rollers 4 can be supported.

[0022] Please see Figure 2-4 The connecting frame 3 is internally connected to a threaded rod 5, which is threaded to the base 1. A retaining ring 51 is fixedly connected to the outside of the threaded rod 5, which is rotatably connected to the connecting frame 3 and contacts the base 1. The retaining ring 51 is designed to limit the movement of the threaded rod 5. A knob 52 is fixedly connected to the end of the threaded rod 5 away from the base 1 and contacts the connecting frame 3. A guide rod 53 is fixedly connected to the side of the connecting frame 3 closest to the base 1. A guide block 54 is fixedly connected to the outside of the guide rod 53. The guide rod 53 is slidably connected to the base 1, and the guide block 54 is slidably connected to the base 1. A fixing rod 55 is fixedly connected to the inside of the base 1 and is slidably connected to the guide block 54. The fixing rod 55 is designed to limit the movement of the guide block 54. A limit mechanism 6 is provided on the roller 4.

[0023] Please see Figure 2-4 The limiting mechanism 6 includes a sleeve 61, a slide rod 62 is slidably connected inside the sleeve 61, a top block 63 is fixedly connected to the end of the slide rod 62 away from the sleeve 61, a limiting ring 64 is fixedly connected inside the sleeve 61, the limiting ring 64 is slidably connected to the slide rod 62, and a spring 65 is provided inside the sleeve 61, one end of the spring 65 is in contact with the slide rod 62, and the other end of the spring 65 is in contact with the sleeve 61. Through the setting of the spring 65, the top block 63 can be driven to fit with the nanocrystalline ribbon. Through the design of the limiting mechanism 6, the nanocrystalline ribbon can remain stable after installation.

[0024] The specific implementation process of this utility model is as follows: In use, by rotating the knob 52, the knob 52 drives the threaded rod 5 to rotate, causing the threaded rod 5 to move threadedly with the base 1, thereby causing the connecting frame 3 to slide the guide rod 53 within the base 1, and causing the connecting frame 3 to slide the square block 43 out of the roller 4, thus releasing the limitation on the roller 4. By moving the top block 63 closer to the roller 4, the top block 63 drives the slide rod 62 to slide within the limiting ring 64, causing the slide rod 62 to compress the spring 65. Then, the nanocrystalline ribbon is installed with the roller 4, so that the nanocrystalline ribbon is sleeved with the top block 63. Then, the top block 63 is released, and the spring force of the spring 65 drives the slide rod 62 to move, causing the slide rod 62 to drive the top block 63 to limit the nanocrystalline ribbon.
