Description

Technical Field

[0001] The utility model provides a novel three-dimensional winding device for amorphous strips, belonging to the field of automatic control and production. Background Art

[0002] At present, in the textile chemical fiber, new energy and new material industries represented by lithium battery and transformer amorphous strips, the winding station of the automated continuous production process usually uses a winding device to wind and roll finished products or semi-finished products.

[0003] For example, transformer losses account for a large proportion of power system losses, and reducing transformer losses is of great significance to improving the efficiency of power grid power supply and distribution systems. Amorphous strip core transformers are new energy-saving transformers that use amorphous strips instead of silicon steel sheets as core materials. Compared with silicon steel sheet core transformers, their no-load losses are reduced by more than 70%, and their no-load current is reduced by about 80%. They are currently the most ideal distribution transformers for energy saving.

[0004] With the promotion and application of amorphous transformers in China and the improvement of quality requirements, higher requirements are placed on the performance indicators of the winding structure of the core of amorphous strip transformers in terms of winding efficiency, effective adjustment and control accuracy of strip surface tension, and correction feedback sensitivity.

[0005] In view of this, this patent application is proposed. Utility Model Content

[0008] Furthermore, a group of sensors and a proportional valve for adjusting the cylinder pressure to change its horizontal stroke are installed on one side of the cylinder.

[0009] Furthermore, two sets of slide rails are arranged in a horizontal direction on the side of the frame structure.

[0010] Furthermore, the wrap angle of the amorphous strip on the floating roll is ≥120°.

[0011] Furthermore, a plurality of roller devices are arranged between the unwinding device and the floating tension adjustment assembly, and the amorphous strip extends from the unwinding device through the roller devices and then changes direction to be wound through the floating tension adjustment assembly.

[0012] Furthermore, a plurality of roller devices are arranged between the floating tension adjustment assembly and the deviation correction device, and the amorphous strip extends from the floating tension adjustment assembly through the roller device and then changes direction and winds through the deviation correction device.

[0013] Furthermore, a plurality of roller devices are arranged between the deflection correcting device and the winding device, and the amorphous strip extends from the deflection correcting device, passes through the roller device, and is finally redirected and wound around the winding device.

[0014] In summary, the advantages of the three-dimensional winding device for amorphous strips proposed in this application are:

[0015] 1. The overall structure of the device is compact, the material winding efficiency is high and the operation is simple, which is conducive to being applicable to different production scenarios.

[0016] 2. The floating tension adjustment component meets the design requirements of precise tension adjustment and real-time feedback of tension data with its novel design and layout.

DETAILED DESCRIPTION

[0023] The technical solution proposed in this application will be described clearly and completely below in conjunction with the above-mentioned drawings. For those skilled in the art, the described embodiments are only part of the solution of this application rather than all embodiments. Based on the following embodiments, all other embodiments obtained by those skilled in the art without making creative work should belong to the protection scope of this application.

[0024] Embodiment 1, as Figures 1 to 3 As shown, the present application proposes a novel three-dimensional winding device for amorphous strips used for automated continuous production of iron core transformers, the device comprising a frame structure 1, an unwinding device 2 and a rewinding device 7 are respectively arranged at both ends of one side of the frame structure 1; a floating tension adjustment component 5 and a deviation correction device 6 are sequentially arranged between the unwinding device 2 and the rewinding device 7;

[0025] Among them, the unwinding device 2 is used for material output of the amorphous strip 4; the roller device 3 is used for redirecting the amorphous strip 4 when it is wound; the floating tension adjustment component 5 is used to control the adjustment of the surface tension of the amorphous strip 4 during the winding operation; the deviation correction device 6 is used for deviation correction and correction of the amorphous strip 4 along the winding axis; the winding device 7 is used for iron core winding.

[0026] The working principle of the above-mentioned three-dimensional winding device for amorphous strip is as follows: the amorphous strip 4 passes from the unwinding device 2 through the roller device 3 and then passes through the floating tension adjustment component 5, and then passes through the floating tension adjustment component 5 and then passes through the roller device 3 and then passes through the deviation correction device 6, and finally passes through the roller device 3 and completes the winding operation at the winding device 7.

[0027] An array of roller devices 3 is provided between the unwinding device 2 and the floating tension adjustment assembly 5. The amorphous strip 4 extends from the unwinding device 2 through the roller device 3 and then changes direction to be wound through the floating tension adjustment assembly 5.

[0028] A plurality of roller devices 3 are arranged between the floating tension adjustment assembly 5 and the deviation correction device 6. The amorphous strip 4 extends from the floating tension adjustment assembly 5 through the roller device 3 and then changes direction and winds through the deviation correction device 6.

[0029] A plurality of roller devices 3 are arranged between the deflection correcting device 6 and the winding device 7 . The amorphous strip 4 extends from the deflection correcting device 6 , passes through the roller devices 3 , and is finally redirected and wound around the winding device 7 .

[0030] The floating tension adjustment assembly 5 comprises a floating roller 14 for winding and redirecting the amorphous strip 4, the bottom of the floating roller 14 is slidably connected to two sets of slide rails 13 arranged in the horizontal direction, one side of the floating roller 14 is horizontally fixedly connected to the driving end of the cylinder 15, and a group of sensors 16 and a proportional valve 17 for adjusting the cylinder pressure to change its horizontal stroke are installed on one side of the cylinder 15;

[0031] Two sets of slide rails 13 are arranged horizontally on the side of the frame structure 1, so that the interference effect of their own weight on the surface tension control and feedback sensitivity of the amorphous strip 4 can be reduced accordingly; the sensor 16 is used to detect the position of the floating roller 14 in real time and feed back information to the PLC, and the proportional valve 17 adjusts the internal air pressure of the cylinder 15 according to the position of the floating roller 14 fed back by the sensor 16, thereby adjusting the travel distance of the cylinder 15 to push and pull the floating roller 14 in the lateral direction.

[0032] exist Figure 3 In the figure, the function of the floating tension adjustment component 5 is to buffer and compensate for the difference between the unwinding speed of the unwinding device 2 and the winding speed of the winding device 7. When the difference between the two is larger, the surface tension of the amorphous strip 4 is larger or smaller, which is not conducive to the winding quality of the amorphous strip 4. In this regard, by adjusting the stroke of the cylinder 15 itself, the displacement of the floating roller 14 sliding along the slide rail 13 is adjusted, and finally the angle θ of the amorphous strip 4 wound and redirected by the floating roller 14 changes.

[0033] Specifically, in the figure, Ⅰ is the amorphous strip material path when the floating roller 14 is at the left limit position of the slide rail 13, Ⅱ is the amorphous strip material path when the floating roller 14 is at the right limit position of the slide rail 13, and M is the maximum stroke value of the cylinder 15. The maximum difference between Ⅰ and Ⅱ in the material path is about 2M, and the minimum is M (at this time, the angle θ is 60°), so the roll wrap angle of the amorphous strip 4 on the floating roller 14 is greater than 120°.

[0034] It should be noted that those skilled in the art can also make changes and modifications to the above-mentioned implementations. Therefore, the present application is not limited to the above-mentioned specific implementations, and any obvious improvements, substitutions or modifications made by those skilled in the art on the basis of the present application belong to the protection scope of the present application.

[0035] In addition, although some specific terms are used in this specification, these terms are only for convenience of description and do not constitute any limitation to the present invention.
