Description

Technical Field

[0001] This utility model relates to the field of steel strip winding technology, specifically a vertical stainless steel strip winding machine. Background Technology

[0002] Stainless steel strips can be processed into automotive trim strips, etc. When processing stainless steel strips, especially flexible ones, the finished products are generally stored by winding them using a winding machine. During winding, the steel strip is evenly wound.

[0003] The prior art (Chinese patent application number CN202111607104.5, published on December 5, 2023) discloses a steel strip winding device, relating to the field of steel strip production equipment technology. It includes a winding equipment frame, a fixed shaft, an adjusting shaft, a control console, and a winding shaft. The fixed shaft is internally located within the winding equipment frame, and the adjusting shaft is located on the side of the fixed shaft. This invention utilizes the telescopic movement of a telescopic column to press a moving block against the outside of the moving block. This, combined with the telescopic movement of a telescopic rod, causes the pressing block to press down, increasing the fixing performance of the moving block. Then, the pressure of the buffer pad causes the pressing plate to press against the buffer column. The elasticity of the buffer column buffers the force. Finally, the pressure of the pressing pad presses against the air pressure pad, and the rebound energy of the air pressure pad buffers the force. This solves the problem of loose steel strip winding caused by the inconvenience of adjusting the tension of the winding device. It facilitates the device's use of buffer elasticity to increase fixing performance and allows for convenient fixing after adjustment.

[0004] When current steel strip winding machines wind steel strips, the large rotational force required for winding necessitates a tight connection between the winding drum and the device. However, a tight connection makes it difficult to install and remove the winding drum, while a loose connection can cause slippage during winding. Furthermore, when the winding machine uses a single winding drum to wind and wrap the steel strip, it is not convenient to quickly change the winding drum for switching purposes.

[0040] 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.

[0041] Please see Figures 1-6Example 1: This utility model provides the following technical solution: A vertical stainless steel strip winding machine includes a base 1 and a positioning roller 3 above it. A winding cylinder 4 for winding steel strip is fitted on the outer side of the positioning roller 3. A movable disk 2 is rotatably connected below the positioning roller 3, and a rotating mechanism is provided in the middle and lower part of the movable disk 2 to control the rotation of the movable disk 2. The positioning rollers 3 are evenly distributed on the movable disk 2, and a drive shaft 5 is connected below the positioning rollers 3 to provide power for the rotation of the positioning rollers 3. A docking transmission mechanism is provided below the drive shaft 5. A limit mechanism is provided in the middle of the positioning roller 3 to position the connection between the positioning roller 3 and the winding cylinder 4. After the docking transmission mechanism and the drive shaft 5 are connected, the limit mechanism is triggered to limit the winding cylinder 4. The rotating mechanism includes a mounting shaft 22 and a second motor 23. The mounting shaft 22 is fixed in the middle and lower part of the movable disk 2, and the second motor 23 is connected below the mounting shaft 22. The second motor 23 is fixedly installed above the base 1.

[0042] In use, the winding cylinder 4 can be placed outside the positioning roller 3. A support bracket 301 is set below the positioning roller 3 to provide bottom support for the winding cylinder 4. The second motor 23 drives the mounting shaft 22 to drive the movable disk 2 to rotate, which can move the positioning roller 3 and switch the positioning roller 3 used. The positioning roller 3 with the winding cylinder 4 installed can also be switched to the winding station, or the winding cylinder 4 that has completed the winding operation can be switched to an idle position for disassembly. When it is necessary to control the rotation of the winding cylinder 4, the positioning roller 3 is provided with rotational power through the docking transmission mechanism.

[0043] Example 2: Based on Example 1, a support ring 24 is fixed below the movable disc 2, and balls 25 are evenly installed on the lower surface of the support ring 24. The balls 25 are in contact with the surface of the base 1. The limiting mechanism includes a limiting block 11, a return spring 12, a movable rod 13, a pressing block 14, and a connecting rod 15. The limiting blocks 11 are evenly distributed on the surface of the positioning roller 3. The return spring 12 is fixed inside the limiting block 11 to provide an inward returning force to the limiting block 11. The movable rod 13 is fixed inside the limiting block 11, and a horizontal sliding structure is formed between the movable rod 13 and the positioning roller 3. The pressing block 14 is set at the inner end of the movable rod 13, and the outer side of the pressing block 14 is designed with an inclined structure. A vertical sliding structure is formed between the pressing block 14 and the positioning roller 3. The connecting rod 15 is fixed below the pressing block 14 to control the movement of the pressing block 14.

[0044] The support ring 24 can provide auxiliary support for the movable disc 2, and together with the ball bearing 25, it reduces its rotational resistance. In the default state, the limit block 11 remains in a contracted state under the action of the return spring 12, and does not squeeze the winding cylinder 4, which facilitates the placement and removal of the winding cylinder 4.

[0045] Example 3: Based on Example 2, a docking transmission mechanism is disclosed, including a connecting groove 6, a connecting block 7, an output shaft 8, a first motor 9, a transmission block 10, and a vertical control mechanism. The connecting groove 6 is located below the drive shaft 5 and has a rectangular structure. The lower end of the connecting rod 15 is located inside the connecting groove 6. The connecting block 7 is located below the connecting groove 6, and a concave-convex fit structure is formed between the connecting block 7 and the connecting groove 6. The output shaft 8 is located below the connecting block 7 and forms a sliding structure between the output shaft 8 and the connecting block 7. The first motor 9 is located below the output shaft 8 and controls the rotation of the output shaft 8. The transmission block 10 is fixed above the output shaft 8, and the output shaft 8 is driven by the transmission block 10. The movable connecting block 7 rotates, and a vertical control mechanism is set on the outside of the connecting block 7 to control the movement of the connecting block 7. The vertical control mechanism includes an auxiliary disk 16, a connecting frame 17, a connecting seat 18, and an electric push rod 19. The auxiliary disk 16 is fixed on the outside of the connecting block 7. The connecting frame 17 is set on the left side of the auxiliary disk 16, and the connecting frame 17 and the auxiliary disk 16 form a sliding connection. The connecting seat 18 is fixed on the left end of the connecting frame 17. The electric push rod 19 is fixed below the connecting seat 18 to control the movement of the connecting seat 18. A positioning block 20 is fixed on the top of the connecting seat 18, and the top of the positioning block 20 is designed with an inclined structure. The interior of the movable disk 2 has a positioning groove 21 that is opposite to the positioning block 20.

[0046] When the positioning roller 3 is driven, the connecting seat 18 can be pushed upward by the electric push rod 19, so that it drives the auxiliary plate 16 and the connecting block 7 to move upward through the connecting frame 17. At the same time, the positioning block 20 is inserted into the positioning groove 21 to position the movable plate 2. After the connecting block 7 moves into the connecting groove 6, it squeezes the connecting rod 15 in the connecting groove 6, pushing the connecting rod 15 to move upward. The connecting rod 15 pushes the squeezing block 14 to move upward, so that the squeezing block 14 squeezes the movable rod 13, driving the limiting block 11 to move, so that the limiting block 11 and the winding cylinder 4 are connected, so that the subsequent positioning roller 3 can stably drive the winding cylinder 4 to rotate and wind the steel strip.
