Description

Technical Field

[0001] The utility model provides a length-recording mechanism for three-dimensional winding of an amorphous strip and a winding device using the length-recording mechanism, 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 technical requirements are put forward for the winding efficiency of the core winding structure of amorphous strip transformers, especially the control accuracy and feedback sensitivity of the overall size and weight indicators after winding.

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

[0006] The present application proposes a length recording mechanism and an amorphous strip three-dimensional winding device using the mechanism, aiming to solve the problems and defects existing in the prior art and adopting a length recording method of a roller and a rotary incremental encoder, so as to realize automatic recording of the length of the strip during the unwinding process, thereby achieving the purpose of effectively improving the strip cutting efficiency, accurately recording the weight and external dimensions of the three-dimensional iron core and improving the quality of the winding operation.

[0007] To achieve the above-mentioned design purpose, the length recording mechanism includes a supporting base, on which a supporting frame is installed, on which a group of ceramic rollers and a group of length recording rubber-coated rollers for winding, rotating and redirecting the amorphous strip are arranged along the horizontal axis, and a rotary incremental encoder is connected to one side end of the length recording rubber-coated roller, and the rotary incremental encoder communicates with the PLC in real time to feedback and record the length value of the strip.

[0008] Furthermore, both ends of the ceramic roller are mounted on a support frame through ceramic roller rolling bearings.

[0009] Furthermore, both ends of the length-recording rubber-coated roller are installed on the support frame through the rubber-coated roller rolling bearings.

[0010] Furthermore, a sponge roller connected to a support frame is vertically arranged above the length-recording rubber-coated roller, and the sponge roller presses down on the amorphous strip wound and rotating on the length-recording rubber-coated roller.

[0011] Furthermore, both ends of the sponge roller are arranged on a fixed plate of a U-shaped structure through a sponge roller rolling bearing shaft, and the top of the fixed plate is connected to at least one set of guide shafts and the output end of the cylinder, and the output ends of the guide shafts and the cylinder are respectively vertically penetrated and sleeved on the top of the support frame.

[0012] Furthermore, a hydraulic buffer device is connected to the top end of the guide shaft.

[0013] Based on the above-mentioned length-measuring mechanism, the present application also proposes a novel three-dimensional winding device for amorphous strip. The length-measuring mechanism is installed on a frame on one side of an unwinding assembly through a supporting base. After the amorphous strip is unloaded from the unwinding assembly, it passes through a ceramic roller and a length-measuring rubber-coated roller and is rotated and redirected.

[0014] In summary, the length recording mechanism and the amorphous strip three-dimensional winding device using the mechanism have the following advantages:

[0015] 1. The present application proposes a length recording mechanism that can be applied to a three-dimensional winding device for amorphous strips. The mechanism adopts a roller and a rotary incremental encoder assembly to automatically record the length of the strip in real time during the unwinding process, thereby significantly improving the efficiency of strip cutting and the precise control of the weight of the three-dimensional iron core, and can ensure the accuracy of the final forming size of the iron core.

[0016] 2. The present application is applied to the existing three-dimensional winding device for amorphous strips, which is beneficial to optimizing the structure and quantity of functional modules of the winding device, and can correspondingly save equipment costs and improve the reliability of equipment operation.

[0017] 3. The present application adopts a cylinder to drive the sponge wheel to move up and down, and the sponge wheel provides a downward pressure force to increase the friction between the strip and the length-recording rubber wheel, thereby efficiently and accurately recording the length value of the strip, with high measurement accuracy.

[0018] 4. This application adopts a new layout scheme, which can provide real-time feedback on the length of the strip and prevent the rubber-coated length-recording wheel and the strip from slipping, which is beneficial to further improve the length-recording accuracy.

[0026] In order to further improve the friction coefficient between the length-recording rubber-coated roller 1-2 and the amorphous strip 2-4, so as to efficiently and accurately record and feedback the length value of the amorphous strip 2-4, a sponge roller 1-4 which can be raised and lowered and connected to the support frame 1-8 is arranged vertically above the length-recording rubber-coated roller 1-2. The sponge roller 1-4 presses down on the amorphous strip 2-4 wound and rotating on the length-recording rubber-coated roller 1-2, so as to improve and maintain the friction coefficient between the length-recording rubber-coated roller 1-2 and the amorphous strip 2-4, and provide reliable support for the rotary incremental encoder 1-3 to measure the strip length.

[0027] Specifically, both ends of the sponge roller 1-4 are axially arranged on a U-shaped fixed plate 1-5 through a sponge roller rolling bearing 2-3, and the top of the fixed plate 1-5 is connected to at least one set of guide shafts 1-6 and the output ends of the cylinder 1-7, and the output ends of the guide shafts 1-6 and the cylinders 1-7 are respectively vertically penetrated and sleeved on the top of the support frame 1-8; driven by the cylinder 1-7, the fixed plate 1-5 drives the sponge roller 1-4 to rise and fall vertically, and when the sponge roller 1-4 is pressed down on the upper surface of the amorphous strip 2-4, the friction coefficient between the lengthening rubber-coated roller 1-2 and the amorphous strip 2-4 can be increased.
