[0002] Amorphous ribbons generally refer to solid thin ribbons of a certain thickness formed by rapidly cooling liquid metal, resulting in an amorphous alloy structure with short-range order and long-range disorder in atomic arrangement. They possess excellent magnetic properties, corrosion resistance, wear resistance, high hardness, high strength, and high resistivity, and are widely used in fields such as electronics, aviation, aerospace, machinery, and microelectronics.

[0003] Amorphous ribbons typically need to be cut into different widths to suit various applications. Multiple narrow strips cut from a single wide strip are wound by different winding devices.

Currently, most conveyor rollers are detachably attached to the frame. To adjust the tension for different ribbon specifications, the conveyor rollers must be removed from their original positions and reinstalled in new locations. This tension adjustment process is time-consuming and significantly impacts production efficiency. Utility Model Content

Therefore, a feature defined as "first," "second," or "third" may explicitly or implicitly include one or more of that feature.

[0028] 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 direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0029] like Figure 1-3As shown in the schematic embodiment of the automatic cutting and rewinding device for amorphous strip of this utility model, the automatic cutting and rewinding device for amorphous strip includes at least: an unwinding device 1, a cutting device 2, a winding device 3, and a tension regulating device 4; both the winding device 3 and the unwinding device 1 are provided with a spool for detachably connecting to the roll, and a winding and unwinding motor for driving the spool to rotate around the spool axis; the amorphous strip is wound on the roll.

[0030] The cutting device 2 is located between the unwinding device 1 and the winding device 3; multiple winding devices 3 are provided; tension control devices 4 correspond one-to-one with winding devices 3, and each tension control device 4 is located on the side of its corresponding winding device 3 close to the cutting device 2.

[0031] The tension control device 4 includes: a slide 41, a conveyor roller 42, and a first linear drive device 43; the conveyor roller 42 is parallel to the axis of the winding device 3, the conveyor roller 42 is mounted on the slide 41, and the first linear drive device 43 is used to drive the slide 41 to slide linearly in a direction perpendicular to the conveyor roller 42.

[0032] The single strip output from the self-unwinding device 1 is cut into multiple narrow strips by the cutting device 2. All narrow strips are wound around different tension control devices 4 and then wound up by the winding device 3 corresponding to each tension control device 4. During the operation of the tension control device 4, the first linear drive device 43 drives the slide 41 to move, thereby changing the position of the conveyor roller 42, thus achieving rapid adjustment of the tension of the narrow strips and reducing the impact of tension control on production efficiency.

[0033] Furthermore, the automatic cutting and rewinding device for amorphous ribbon also includes a frame 5, and the unwinding device 1, the cutting device 2, the winding device 3, and the tension control device 4 are all installed on the frame 5.

[0034] In some embodiments, the tension control device 4 further includes a tension sensor for detecting the tension of the strip. Based on the detection results of the tension sensor, the tension of the strip can be quickly and accurately determined, thereby enabling rapid and accurate adjustment of the position of the conveyor roller 42.

[0035] Furthermore, the tension sensor is electrically connected to the first linear drive device 43 so as to automatically adjust the output of the first linear drive device 43 according to the tension sensor, thereby realizing rapid adjustment of the strip tension.

[0036] In some embodiments, the tension control device 4 further includes a position sensor 44, which detects the position of the slide 41. Based on the detection result of the position sensor 44, it can be quickly and accurately determined whether the slide 41 has reached the predetermined position, and thus infer whether the position of the conveyor roller 42 meets the required production requirements. If the slide 41 has not reached the predetermined position, the position of the conveyor roller 42 does not meet the required production requirements, and the output of the first linear drive device 43 is continuously adjusted until the slide 41 reaches the predetermined position. If the slide 41 reaches the predetermined position, the position of the conveyor roller 42 meets the required production requirements, and the output end of the first linear drive device 43 stops moving.

[0037] Furthermore, the position sensor 44 is electrically connected to the first linear output device to achieve automatic adjustment, thereby further improving the efficiency and accuracy of tension adjustment.

[0038] Furthermore, the position sensor 44 is a non-contact position sensor to reduce the interference of the position sensor 44 on the movement of the slide 41, increase the moving speed of the slide 41, and further improve the tension adjustment efficiency.

[0039] In some embodiments, the tension control device 4 further includes a guide rod 45; the slide 41 is sleeved on the guide rod 45 and slides on the guide rod 45, and the two ends of the guide rod 45 are fixed.

[0040] Furthermore, the guide rod 45 is connected to the frame 5 at both ends.

[0041] Furthermore, the frame 5 includes a mounting plate 51 and mounting brackets 52; each end of the guide rod 45 is connected to a mounting bracket 52, and both mounting brackets 52 are connected to the mounting plate 51. The mounting plate 51 is provided with a strip-shaped hole, through which the conveyor roller 42 passes and slides. The mounting plate 51 can reduce the contact between the strip and the guide rod 45 and the slide block 41, thus protecting the strip.

[0042] Furthermore, the conveyor roller 42 includes a coaxial roller body 421 and a connecting shaft 422. The connecting shaft 422 passes through and is connected to the roller body 421. The roller surface of the roller body 421 is used to carry the strip material. The connecting shaft 422 passes through a slotted hole and is connected to the slide block 41. There is a gap between the roller body 421 and the mounting plate 51 to reduce the frictional contact between the strip material and the mounting plate 51 and protect the strip material.

[0043] In some embodiments, the first linear drive device 43 is a hydraulic cylinder or a pneumatic cylinder, which is simple in structure, low in cost, and easy to maintain and replace.

[0044] Furthermore, the first linear drive unit 43 is a low-friction cylinder.

[0045] In some embodiments, the automatic amorphous strip cutting and rewinding device further includes a moving device 6 corresponding to each of the winding devices 3; the moving device 6 includes: a fixed base 61 and a second linear drive device 62; the fixed base 61 is fixed in position, and each winding device 3 is linearly slidably connected to the corresponding fixed base 61; the second linear drive device 62 is used to drive the corresponding winding device 3 to slide; the sliding direction of the winding device 3 is horizontal and perpendicular to the axis of the winding device 3.

[0046] When the tension regulating device 4 is unable to provide the strip with the tension required for production, the second linear drive device 62 can drive the winding device 3 to move closer to or further away from the unwinding device 1, thereby adjusting the tension of the strip.

[0047] In some embodiments, the moving device 6 further includes a plurality of parallel linear guides 63 detachably connected to the fixed base 61; the winding device 3 is provided with a sliding groove corresponding to each linear guide 63, with each groove slidingly engaging with its corresponding linear guide 63. The plurality of linear guides 63 can improve the limiting effect on the moving direction of the winding device 3, and the detachable arrangement of the linear guides 63 also facilitates the extension of the service life of the moving device 6 by replacing the linear guides 63.

[0048] In some embodiments, the chute is located at the bottom of the winding device 3 to improve the reliability of the sliding fit between the guide rail 63 and the winding device 3 by means of the weight of the winding device 3 itself.

[0049] In some embodiments, the second linear drive device 62 is a hydraulic cylinder or a pneumatic cylinder, which is simple in structure, low in cost, and easy to maintain and replace.

[0050] Furthermore, the second linear drive unit 62 is a low-friction cylinder.

[0051] In some embodiments, all winding devices 3 are at different heights to prevent the moving device 6 from interfering with the movement of the winding device 3.

[0054] 2. The winding device 3 can be close to or far from the unwinding device 1, thereby assisting the tension control device 4 in adjusting the tension of the strip.
