Description

Technical Field

[0001] This application proposes a novel amorphous ribbon slitting equipment, belonging to the field of automation control and production. Background Technology

[0002] Currently, in the textile and chemical fiber industry, as well as the new energy and new materials industry represented by lithium batteries and transformer amorphous strips, the winding station of automated continuous production processes usually uses a winding mechanism to wind finished or semi-finished products.

[0003] Specifically, amorphous strip manufacturers typically package and sell their products in large-diameter rolls to ensure equipment continuity and production efficiency. For processing companies using this material, particularly those manufacturing three-dimensional coiled transformers, large-diameter rolls present several inconveniences during processing, such as incompatibility with production equipment and processes, difficulty in handling, and the risk of roll collapse during transport. Therefore, before processing, large-diameter rolls need to be broken down into smaller diameter rolls to accommodate the equipment and processing requirements of the processing companies.

[0004] Existing technologies suffer from problems such as difficult handling and easy roll collapse during the splitting of large rolls due to their heavy weight. Furthermore, uneven tension, interlayer wrinkles, and misalignment are prone to occur during the winding of smaller rolls. Therefore, there is an urgent need to explore a slitting device for splitting large rolls of amorphous ribbon into smaller rolls to solve these problems. In view of this, this application is hereby submitted. Summary of the Invention

[0005] The amorphous strip slitting equipment described in this application is specifically designed for splitting large rolls of amorphous strip into smaller rolls. It aims to address many problems existing in the processing of large-diameter strips in the prior art. The design aims to achieve automatic slitting and improve winding tension balance, thereby significantly improving production efficiency and product qualification rate through dynamic tensioning and process control mechanisms between the unwinding and rewinding mechanisms.

[0006] Therefore, the amorphous strip slitting equipment proposed in this application includes a frame, an unwinding mechanism fixedly connected to both ends of the same side of the frame, and a rewinding mechanism slidably connected to both ends. A process control mechanism including an array of rollers for relay transmission of the strip is provided between the unwinding mechanism and the rewinding mechanism. The process control mechanism includes an array of rollers arranged along a horizontal axis, a length counting roller with a different vertical height from the adjacent rollers arranged between the array of rollers, and a guide mechanism.

[0007] The length counting roller is equipped with an encoder for recording the length of the strip passing through in real time.

[0008] The guide mechanism consists of arrayed guide shafts and adjusting screws arranged in parallel along the horizontal direction of the mounting base. Each set of guide shafts and adjusting screws is rotatably mounted at both ends via bearings. Two sets of roller seats are slidably fitted onto the arrayed guide shafts and adjusting screws, and each set of roller seats has the same number of arrayed rollers mounted vertically on its axis.

[0009] The unwinding mechanism and the winding mechanism have the same structure and connection method, and a transmission component is provided on the frame to drive the winding mechanism to reciprocate in the horizontal direction.

[0010] The transmission assembly includes an array of guide rail sliders, the bottom of the winding mechanism is slidably connected to the guide rail sliders, the output end of the servo motor is driven and connected to one end of a lead screw assembly arranged in the horizontal direction, and the nut sleeved on the lead screw assembly is fixedly connected to the winding mechanism.

[0011] The unwinding mechanism includes a frame and a drive motor. A main shaft is horizontally mounted on the frame via a bearing assembly. A chuck for winding the strip material is fixed to one end of the main shaft. The output end of the drive motor drives the main shaft to rotate axially via a synchronous belt / pull assembly to drive the chuck to wind the strip material.

[0012] The locking shaft passes through the hollow cavity of the chuck axially via a coiled wire. The locking motor is connected to the locking shaft via a coupling. The locking motor drives the coiled wire in the cavity of the chuck to rotate, thereby achieving radial expansion and contraction of the chuck.

This application adopts a chuck-type expansion assembly for the unwinding and rewinding mechanism. Compared with the mechanical expansion shaft of the prior art, which is prone to jamming, loosening due to easy wear of connecting parts, short service life, and failure to expand due to unstable air pressure of pneumatic expansion shaft, this application can show the characteristics of mature technology and stable structure, and the operation of the whole machine is more stable and reliable. 2. The unwinding and rewinding mechanisms proposed in this application are both equipped with pneumatic braking devices, which can stop quickly after the rewinding is completed, thereby preventing accidents such as strip roll collapse caused by continued rotation due to inertia; 3.

Detailed Implementation

[0016] The technical solution proposed in this application will be clearly and completely described below with reference to the accompanying drawings. For those skilled in the art, the described embodiments are merely a part of, and not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the following embodiments without inventive effort should fall within the protection scope of this application.

[0017] Example 1, such as Figures 1 to 8 As shown, this application proposes an amorphous strip slitting device for automated continuous production of iron core transformers. The device includes a frame 3 fixedly installed by a base 7, an unwinding mechanism 2 fixedly connected to both ends of the same side of the frame 3 and a winding mechanism 6 slidably connected to it, and a process control mechanism 5 for relaying and conveying a series of rollers of strip 1 between the unwinding mechanism 2 and the winding mechanism 6.

[0018] The unwinding mechanism 2 is used to carry and output the large-diameter strip 1, the process control mechanism 5 can redirect and adjust the surface tension of the strip 1 that has been wound, and the winding mechanism 6 is used to wind the strip 1 to finally form a small-diameter coil.

[0019] An operation box 4 for power supply and control of the operation of various mechanisms of the equipment, and a transmission component for driving the winding mechanism 6 to reciprocate in the horizontal direction are provided on the frame 3. The transmission assembly can be a chain and sprocket assembly, a timing belt and pulley assembly, or a gear and rack assembly; the preferred implementation in this embodiment is as follows: The bottom of the winding mechanism 6 is slidably connected to the array of guide rail sliders 8 fixed on the base 7. The output end of the servo motor (not shown in the figure) is driven to one end of the lead screw group 9 arranged in the horizontal direction. The lead screw nut (not shown in the figure) sleeved on the lead screw group 9 is fixed to the winding mechanism 6. Under the drive of the servo motor, the lead screw group 9 rotates on a fixed axis and drives the winding mechanism 6 to move back and forth in the horizontal direction of the base 7, thereby meeting the winding process requirements of strip 1 with different specifications or different roll diameters.

[0020] The unwinding mechanism 2 and the winding mechanism 6 have the same structure and connection method. The following describes the structure, connection relationship and working principle of the unwinding mechanism 2 in detail: The unwinding mechanism 2 includes a frame 204 and a drive motor 208. A main shaft 209 is horizontally mounted on the frame 204 via a bearing assembly 211. A chuck 201 for winding the strip 1 is fixed to one end of the main shaft 209. The output end of the drive motor 208 drives the main shaft 209 to rotate axially via a synchronous belt / pull assembly 207 to drive the chuck 201 to wind the strip 1.

[0021] To improve the stability of the strip 1 being wound on the chuck 201, the following tensioning mechanism design is preferred in this embodiment: Specifically, the locking shaft 210 is axially inserted into the hollow cavity of the chuck 201 via a coiled wire. The locking motor 206 is connected to the locking shaft 210 via a coupling 205. The locking motor 206 drives the coiled wire in the cavity of the chuck 201 to rotate, thereby expanding and contracting the chuck 201 radially. When the strip 1 is wound onto the chuck 201, the locking shaft 210 can be rotated by the locking motor 206 to expand the chuck radially, thereby tightening the strip 1 in the chuck 201 and keeping the two relatively stationary.

[0022] In order to effectively stop the winding operation quickly after the slitting is completed, thereby preventing accidents such as strip roll collapse caused by continued rotation due to inertia, a brake disc 203 and a pneumatic brake 202 for cooperating with the brake disc 203 can be sleeved in the middle section of the main shaft 209.

[0023] The process control mechanism 5 includes a bracket 503 fixed to the frame 3, an array of guide rollers 501 arranged along the horizontal axis on the bracket 503, a length counting roller 502 with a different vertical height from the adjacent guide rollers 501 arranged between the array of guide rollers 501, and a guide mechanism 504; the length counting roller 502 is equipped with an encoder for real-time recording of the length of the strip 1; guide rollers 501 are respectively arranged on both sides of the length counting roller 502, and the strip 1 can have a sufficiently large wrap angle when it is wound and guided from both sides by the guide rollers 501 to the length counting roller 502, so that there is sufficient friction between the strip 1 and the length counting roller 502, preventing slippage from affecting the measurement result of the length counting roller 502.

[0024] The guide mechanism 504 includes a mounting base 504-1, an array of guide shafts 504-4 and an adjusting screw 504-5 arranged parallel to each other in the horizontal direction along the mounting base 504-1. The two ends of each set of guide shafts 504-4 and adjusting screws 504-5 are rotatably mounted by bearings. A rotating handwheel 504-6 is installed on one side of the adjusting screw 504-5. Two sets of roller seats 504-3 are slidably sleeved on the array of guide shafts 504-4 and adjusting screws 504-5. The same number of array rollers 504-2 are vertically mounted on each set of roller seats 504-3.

[0025] During the process of strip 1 being led out by unwinding mechanism 2 and passing through roller 501, length counting roller 502 and guiding mechanism 504, it is clamped from both sides by two sets of rollers 504-2 and provided with horizontal displacement guidance. While reducing sliding friction, it effectively improves winding accuracy and tension uniformity and prevents problems such as misalignment of strip 1 by preventing the strip 1 from running off-center.

[0026] When winding strips 1 of different specifications and models, the distance between the two sets of roller seats 504-3 can be adjusted by manually rotating the handwheel 504-6 and adjusting the lead screw 504-5, thereby adjusting the width of the left and right sets of rollers 504-2 clamping the strip 1, and realizing dynamic adjustment.

[0027] The working principle of the amorphous ribbon slitting equipment described above is as follows: Strip 1 is led out from unwinding mechanism 2, passes through process control mechanism 5, and completes winding operation at winding mechanism 6.

[0028] Specifically, firstly, the large-diameter strip 1 is placed on the chuck 201 of the unwinding mechanism 2, the pneumatic brake 202 clamps the brake disc 203, and the locking motor 206 drives the locking shaft 210 to rotate through the coupling 205, thereby causing the chuck 201 to tighten the strip 1 roll. Then, the locking motor 206 is de-energized, and the operator passes the strip 1 through the roller 501, the length counting roller 502, and the guide mechanism 504 in sequence to complete the strip threading operation. The strip head is then attached to the roll placed on the winding mechanism 6, and the equipment is started to perform the slitting operation. During the slitting process, the length counting roller 502 is equipped with an encoder. The strip 1 will drive the length counting roller 502 to rotate, thereby realizing the real-time measurement of the length of the strip 1. When the set length is reached, the equipment will automatically stop, and the operator will replace the roller and repeat the above operation to continue the work. For strip 1 of different specifications, after the strip 1 is wound and hung on the unwinding mechanism 2, the distance between the two sets of rollers 504-2 of the guide mechanism 504 is adjusted so that the strip 1 will not deviate when passing through the process control mechanism 5. Furthermore, the winding mechanism 6 is driven by the lead screw assembly 9 to move back and forth, so that the end face of the strip at the winding position is flush with the end face of the strip at the unwinding position, in order to adapt to multi-specification strip operations.

[0029] It should be noted that those skilled in the art can make changes and modifications to the above-described embodiments. Therefore, this application is not limited to the specific embodiments described above, and any obvious improvements, substitutions, or modifications made by those skilled in the art based on this application shall fall within the protection scope of this application.
