Abstract
Description
Technical Field
[0001] This utility model relates to the field of lithium electrode sheet slitting and winding technology, and in particular to a device for improving the deflection deformation of the slip shaft in winding equipment. Background Technology
[0002] In the lithium battery industry, to improve production efficiency and meet the ever-increasing market demand, companies are taking measures to optimize production processes. One key way to increase capacity and efficiency is to increase electrode width, increase winding diameter, and increase the number of windings. This approach not only effectively increases output per batch but also reduces unit production costs to some extent. However, as these parameters continue to improve, more stringent requirements are placed on production equipment. In particular, the slip shaft in the winding equipment, as a key factor affecting winding quality and efficiency, directly impacts the alignment and continuity of electrode winding. If the slip shaft cannot meet the demands of high load and high precision, it will lead to a series of problems, such as increased deflection and deformation of the slip shaft, which in turn affects the winding quality of the electrode, and in severe cases, may even cause electrode breakage during winding, resulting in unnecessary losses for the company. Utility Model Content
[0003] The purpose of this utility model is to overcome the shortcomings of the existing technology. In order to achieve the above purpose, a device for improving the deflection deformation of the slip shaft of a winding equipment is adopted to solve the problems mentioned in the background technology.
[0004] A device for improving the deflection deformation of a slip shaft in a winding machine, comprising:
[0005] A support assembly, the support assembly including a first support member and a second support member;
[0006] A guide rail assembly is installed on the first support member;
[0007] Support brackets disposed between the guide rail assemblies; and
[0008] A differential assembly is installed on the second support member;
[0009] The extended support frame slides along the guide rail assembly of the first support member and moves to the position of the differential lock assembly for lateral support. This design, through the cooperation of the guide rail assembly and the support frame, achieves the sliding function of the support frame, enabling it to move precisely to the position of the differential lock assembly as needed, providing effective lateral support and enhancing the stability and reliability of the overall structure.
[0010] As a further embodiment of this invention, the guide rail assembly includes a guide rail pair disposed on the side end face of the first support member, a guide rail slider stop disposed on the fixed end of the guide rail pair, and a double-column cylinder clamping mechanism disposed on the side of the guide rail pair. The guide rail pair and the guide rail slider stop ensure the accuracy and stability of the guide rail assembly, while the double-column cylinder clamping mechanism provides a strong clamping force, ensuring that the support frame will not fall off or shake during sliding, thus improving the overall safety and reliability.
[0011] As a further embodiment of this invention: the dual-column cylinder clamping mechanism includes a dual-column cylinder and a blocking block disposed at the movable end of the dual-column cylinder. The dual-column cylinder design provides a stable clamping force, while the blocking block precisely controls the clamping position of the support frame, avoiding damage or failure caused by improper clamping and improving the overall service life.
[0012] As a further embodiment of this invention, the support frame is slidably mounted on the guide rail pair, and is clamped by a blocking block at the movable end of the double-column cylinder. This design allows the support frame to slide smoothly on the guide rail pair, while the clamping action of the double-column cylinder ensures that the support frame can be firmly fixed in a designated position when needed, thus improving the flexibility and stability of the overall structure.
[0013] As a further aspect of this invention, the blocking block adopts a V-shaped structure. The V-shaped blocking block can better clamp and hold the support frame, avoiding the support frame from shifting due to unstable clamping, which could lead to damage or deformation of the differential shaft.
[0014] As a further embodiment of this invention: the clamping end of the support frame is provided with a support block, and the support block adopts a U-shaped structure. The U-shaped support block can better support components such as the differential shaft, providing a larger contact area and stronger support force, thus ensuring the stability and reliability of the overall structure.
[0015] As a further embodiment of this invention, the differential lock assembly includes a bearing disposed on the second support member, a drum disposed on the outer circumferential side of the bearing, a differential lock shaft disposed on the outer side of the drum, and a mating head disposed on the outer end of the bearing. This design allows the differential lock assembly to rotate and slide smoothly, while the mating head facilitates connection and disassembly with other components, improving the overall structure's flexibility and maintainability.
[0016] As a further aspect of this invention: the support frame is connected between the differential shaft and the bearing, and provides lateral support to the differential shaft. The lateral support of the support frame ensures that the differential shaft will not be damaged or deformed due to uneven force during rotation and sliding, thus improving the stability and service life of the overall structure.
[0017] As a further improvement of this invention, a movable handle is provided on the outer side of the support frame. The movable handle facilitates the movement and adjustment of the support frame by the operator, improving the overall operability and convenience of the structure.
[0018] Compared with the prior art, the present invention has the following technical advantages:
[0019] The above technical solution utilizes a basic structure constructed with a first support and a second support. A guide rail assembly is mounted on the first support, and a support frame is installed between the guide rail assemblies. A differential lock assembly is mounted on the second support. Lateral support is achieved by driving the support frame to slide along the guide rail assembly and precisely position it at the differential lock assembly. This design not only enhances the flexibility and adaptability of the components but also significantly improves the stability and accuracy of lateral support, providing a reliable support solution for various application scenarios. It effectively addresses the problem of large deflection deformation of the differential lock shaft due to its own weight and the increased weight of the electrode sheets as the winding diameter increases. This significantly improves the alignment of the wound electrode sheets and reduces electrode breakage. It creates favorable conditions for the equipment to handle large and multiple windings, thereby increasing the equipment's capacity and efficiency. Attached Figure Description

[0025] 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.
[0026] Please refer to Figure 1 In this embodiment of the present invention, a device for improving the deflection deformation of a slip shaft in a winding device includes:
[0027] A support assembly, the support assembly including a first support member 1 and a second support member 13;
[0028] The guide rail assembly is installed on the first support member 1;
[0029] Support bracket 6 disposed between guide rail assemblies; and
[0030] Slip assembly disposed on second support 13;
[0031] The support frame 6 is slid on the guide rail assembly of the first support member 1 by driving the extension, and moves to the position of the slip assembly to provide lateral support.
[0032] In this embodiment, as Figure 2 As shown in the figure, the diagram is a partially enlarged schematic diagram of the device; the guide rail assembly includes a guide rail pair 2 disposed on the side end face of the first support member 1, a guide rail slider block 3 disposed on the fixed end of the guide rail pair 2, and a double-column cylinder clamping mechanism disposed on the side of the guide rail pair 2.
[0033] In this embodiment, the dual-column cylinder clamping mechanism includes a dual-column cylinder 4 and a blocking block disposed at the movable end of the dual-column cylinder 4. It is bolted to the large plate A of the equipment, which serves as the first support member 1. When the support frame 6 moves into position, the dual-column cylinder 4 drives the blocking block to extend, engaging with the V-groove on the support frame 6 to prevent displacement of the support frame 6.
[0034] In this embodiment, the support frame 6 is slidably disposed on the guide rail pair 2, and the support frame 6 is clamped by the blocking block at the moving end of the double column cylinder 4, wherein the blocking block adopts a V-shaped structure.
[0035] In a specific implementation, two sets of guide rail pairs 2 are used and are bolted together and set in parallel on the large plate A of the equipment, which serves as the first support member 1.
[0036] In this embodiment, a support block 9 is provided at the clamping end of the support frame 6, and the support block 9 adopts a U-shaped structure. Specifically, the U-shaped support block 9 is bolted to the side of the support frame 6, and the U-shaped support block 9 and the outer ring of the bearing 10 are fitted with a small tolerance.
[0037] In this embodiment, as Figure 3 As shown, the figure is a schematic diagram of the cross-sectional structure of the slip assembly; the slip assembly includes a bearing 10 disposed on the second support member 13, a drum 12 disposed on the outer side of the bearing 10, a slip shaft 11 disposed on the outer side of the drum 12, and a mating head 8 disposed on the outer end of the bearing 10.
[0038] The differential shaft 11 is mounted on the large plate B of the equipment, which serves as the second support member 13.
[0039] In this embodiment, the support frame 6 is connected between the slip shaft 11 and the bearing 10, and provides lateral support for the slip shaft 11.
[0040] In this embodiment, a movable handle 7 is provided on the outer side of the support frame 6.
[0041] In this specific implementation, it is applicable to the slitting and winding process in the lithium battery industry. Two sets of guide rail pairs 2 are bolted together and arranged parallel to each other on the large plate A of the equipment, which serves as the first support member 1; the support frame 6 is bolted together and arranged above the guide rail sliders of the two sets of guide rail pairs 2; the moving handle 7 is bolted together and arranged above the support frame 6; the guide rail slider stop 3 is bolted together and arranged on the large plate A of the equipment, which serves as the first support member 1, and the two sets of guide rail slider stops 3 are respectively arranged between the two sets of guide rail pairs 2 to block the guide rail sliders and prevent the sliders from sliding out.
[0042] Support block 9 is bolted to the inside of support frame 6, and can be fitted with the outer ring of bearing 10 with a small tolerance. The double-column cylinder clamping mechanism consists of a double-column cylinder 4 and a V-shaped blocking block. This clamping mechanism is bolted to the large plate A of the equipment, which serves as the first support member 1. After support frame 6 is in place, pressing the button extends the V-shaped blocking block of the double-column cylinder clamping mechanism, engaging with the V-groove on support frame 6 to prevent displacement of support frame 6. The inner ring of bearing 10 is interference-fitted with the differential shaft 11 of the equipment, and the outer ring of bearing 10 is fitted with support block 9 with a small tolerance to support differential shaft 11 and mitigate deformation of differential shaft 11.
[0043] The mating head 8 is bolted to the differential shaft 11 of the equipment, and the bearing 10 is fixed between the mating head 8 and the differential shaft 11. During winding, the differential shaft 11 drives the drum 12 to rotate around its own axis. The outer ring of the bearing 10 does not rotate due to its engagement with the support block 9, while the inner ring of the bearing 10, with an interference fit to the differential shaft 11, rotates with the differential shaft 11. The support block 9 thus supports the differential shaft 11. This improves the deflection deformation of the differential shaft 11 caused by the increased weight of the material roll, enhances the alignment of the electrode roll, and reduces the risk of strip breakage during electrode roll.
