Description

Technical Field

[0001] This utility model relates to the technical field of unwinding devices for nickel alloy strips, specifically an unwinding device for nickel alloy strips with a limiting structure. Background Technology

[0002] Nickel alloy strip is mainly used in the manufacture of nickel-cadmium, nickel-metal hydride, nickel batteries, battery packs, and instruments. During the production process, nickel alloy strip needs to be wound onto a hopper. However, traditional unwinding devices cannot adjust the winding distance according to the width of the nickel alloy strip, resulting in irregular winding of the wound nickel alloy strip. To avoid this, a nickel alloy strip unwinding device has been designed that can adjust the winding distance according to the width of the nickel alloy strip and limit its winding.

[0003] A nickel strip production unwinding device, authorized by announcement number CN117550391B, includes an equipment frame and a coil, comprising: a frame unwinding component: a swivel frame rotatably connected to the inner side of the equipment frame via a shaft, and a first motor mounted on the outer end of the equipment frame; a replacement component: a support block slidably disposed on the inner side of the equipment frame, a U-shaped sleeve slidably connected to the inner side of the equipment frame, and a transmission component and a linkage component disposed on the inner side of the equipment frame; and an anti-detachment component: a limit component disposed on the inner side of the equipment frame. In this invention, firstly, by controlling the rotation of the swivel frame, the positions of the two coils mounted on the swivel frame are switched, achieving rapid replacement of the unwound coil, thereby improving the efficiency of batch nickel strip production. Secondly, by controlling the alternating operation of the insertion shaft and the support block, the support block first engages with the coil, and then the insertion shaft disengages from the coil, ensuring safe replacement of the coil.

[0004] Based on existing solutions and actual production and processing applications, current unwinding devices for nickel alloy strips still have some problems: they are not convenient for flattening nickel alloy strips, they are not convenient for disassembling and replacing the nickel alloy strip take-up cylinder, they are not convenient for adjusting the take-up width according to the size of the nickel alloy strip, and they cannot assist in limiting the winding to avoid deviating during winding. Therefore, this utility model provides an unwinding device for nickel alloy strips with a limiting structure to solve the above-mentioned problems. Utility Model Content

[0006] To achieve the above objectives, the present invention provides the following technical solution: an unwinding device for nickel alloy strip with a limiting structure, comprising: a workbench for installation, and a first mounting frame fixedly installed on the upper left side of the workbench;

[0007] It also includes: a threaded rod, the first mounting frame is provided with a threaded rod, and a first motor is installed at the upper end of the threaded rod. A connecting shaft is connected to the outside of the first motor, and a first roller is provided in the middle of the connecting shaft. A second roller is provided at the lower end of the first roller. A third roller is provided on the right side of the first mounting frame, and a fourth roller is provided on the right side of the third roller.

A second connecting block is connected inside the connecting groove, and a spring is located in the middle of the second connecting block. A receiving cylinder is located at the front end of the fixing block, and sliding grooves are provided on both sides of the receiving cylinder. A sliding ring is connected inside the sliding groove.

[0009] Preferably, the outer side of the threaded rod is connected to the connecting shaft by a thread, and the first roller body forms a rotating structure in the middle of the connecting shaft.

[0013] Preferably, the interior of the connecting groove is connected to the second connecting block by means of a thread, and the spring is set in a fitting state in the middle of the second connecting block.

[0014] Compared with the prior art, the beneficial effects of this utility model are: the unwinding device for nickel alloy strip with limiting structure facilitates the flattening of nickel alloy strip, facilitates the disassembly and replacement of nickel alloy strip take-up cylinder, facilitates the adjustment of the winding width according to the size of nickel alloy strip, and helps to limit and prevent winding deviation.

[0015] 1. Equipped with a threaded rod, a connecting shaft, and a second roller, since some nickel alloy strips are prone to bending before winding, affecting the winding state, the first motor can be started to drive the threaded rod to rotate, so that the threaded rod drives the first roller to press the nickel alloy strip on the upper end of the second roller through the connecting shaft to flatten it. When the nickel alloy strip moves to the right, the first roller and the second roller flatten it by rotating, which facilitates the flattening process of the nickel alloy strip.

[0016] 2. The device is equipped with a fixing block, a first connecting block, and a take-up cylinder. When the wound nickel alloy strip and the take-up cylinder need to be disassembled and replaced, the first connecting block and the second connecting block at the left and right ends of the connector are rotated respectively, so that the second connecting block is disengaged from the inside of the connecting groove. At this time, the springs will drive the first connecting block and the second connecting block to slide to the left and right sides and return to their original positions. Then the take-up cylinder can be grasped and the fixing block is driven to disengage from the inside of the connector, thereby disassembling and replacing the take-up cylinder, which is convenient for disassembling and replacing the nickel alloy strip take-up cylinder.

[0017] 3. Equipped with a take-up cylinder, a chute, and a sliding ring, when it is necessary to wind nickel alloy strips of different widths, in order to avoid the nickel alloy strips becoming messy during winding, the sliding rings set at the front and rear ends of the take-up cylinder are slid along the path of the chute towards the middle of the take-up cylinder until they are adjusted to the appropriate size of the nickel alloy strip. The sliding rings have a large friction force when sliding inside the chute, so the sliding rings will not move due to winding, which makes it easy to adjust the winding width according to the size of the nickel alloy strips and helps to limit and prevent winding deviation.

[0024] 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.

[0025] Please see Figure 1-5 This utility model provides a technical solution: an unwinding device for nickel alloy strip with a limiting structure, including a worktable 1, a first mounting frame 2, a threaded rod 3, a first motor 4, a connecting shaft 5, a first roller 6, a second roller 7, a third roller 8, a fourth roller 9, a second mounting frame 10, a fifth roller 11, a first gear 12, a transmission belt 13, a second gear 14, a connector 15, a second motor 16, a fixing block 17, a slot 18, a first connecting block 19, a connecting groove 20, a second connecting block 21, a spring 22, a take-up cylinder 23, a sliding groove 24, and a sliding ring 25.

[0026] When it is necessary to flatten nickel alloy strip, such as Figure 1 and Figure 3 As shown, the first mounting frame 2 has a threaded rod 3 inside, and the first motor 4 is mounted on the upper end of the first motor 4. The threaded rod 3 is connected to the outer side of the connecting shaft 5, and the middle of the connecting shaft 5 is provided with a first roller 6. The lower end of the first roller 6 is provided with a second roller 7. The right side of the first mounting frame 2 is provided with a third roller 8, and the right side of the third roller 8 is provided with a fourth roller 9. First, the nickel alloy strip to be unwound is placed on the upper end of the second roller 7. The first motor 4 is started to drive the threaded rod 3 to rotate. The outer side of the threaded rod 3 is connected to the connecting shaft 5 by a thread. Therefore, when the threaded rod 3 drives the first roller 6 to move downward through the connecting shaft 5, it fits against the upper end of the nickel alloy strip on the second roller 7. When the nickel alloy strip is unwound and transported to the right, the rotation of the first roller 6 and the second roller 7, as well as the pressure between them, flattens the nickel alloy strip. This is the method of flattening the nickel alloy strip.

[0027] When using an unwinding device for nickel alloy strip with a limiting structure, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, a fifth roller 11 is mounted on the left side of the second mounting bracket 10, and a first gear 12 is provided at the rear end of the fifth roller 11. A transmission belt 13 is connected to the outer side of the first gear 12. A second gear 14 is connected to the inner right end of the transmission belt 13, and a connector 15 is provided inside the second gear 14. A second motor 16 is provided at the rear end of the connector 15, and a fixing block 17 is installed inside the front end of the connector 15. A slot 18 is provided in the middle of the fixing block 17. A first connecting block 19 is connected inside the left end of the slot 18, and a connecting groove 20 is provided at the right end of the first connecting block 19. A second connecting block 21 is connected inside the connecting groove 20, and a spring 22 is provided in the middle of the second connecting block 21. A take-up cylinder 23 is provided at the front end of the fixing block 17, and sliding grooves 24 are provided on both sides of the take-up cylinder 23. A sliding ring 25 is connected inside the sliding grooves 24. First, the winding distance is adjusted according to the width of the nickel alloy strip to assist in the winding and limiting of the nickel alloy strip. To prevent deviation during winding, the sliding ring 25 is adjusted by moving along the path of the groove 24 on the left and right sides of the take-up cylinder 23. After the position is adjusted, the second motor 16 is started to drive the second gear 14 and the take-up cylinder 23 to rotate through the connector 15. The take-up cylinder 23 winds up the nickel alloy strip, while the second gear 14 drives the fifth roller 11 and the first gear 12 to rotate through the transmission belt 13. The fifth roller 11 assists in winding the nickel alloy strip. When the take-up cylinder 23 needs to be disassembled after winding, the first connecting block 19 and the second connecting block 21 on the left and right sides of the connector 15 can be rotated respectively, so that the second connecting block 21 is disengaged from the inside of the connecting groove 20. The spring 22 then drives the first connecting block 19 and the second connecting block 21 to disengage from the inside of the hole groove 18. When the take-up cylinder 23 is held and the fixing block 17 is lifted upward, the take-up cylinder 23 can be disassembled. This is the usage method of the unwinding device for nickel alloy strip with limiting structure.
