Description

Technical Field

[0001] This application relates to the field of transfer roller technology, and in particular to a transfer roller structure with adjustable primer width. Background Technology

[0002] In the manufacturing process of lithium-ion batteries, the coating process plays a crucial role. Because the adhesion and conductivity between the positive electrode active material and the current collector are relatively weak, a carbon coating layer is typically applied to the surface of the positive electrode current collector to improve the overall battery performance. This carbon coating layer not only significantly enhances the adhesion between the active material and the current collector but also effectively improves conductivity, thereby ensuring that the battery's charge / discharge efficiency and cycle life reach ideal levels. During the coating process, the coating roller, as the direct carrier of the adhesive, has a decisive influence on the uniformity and thickness consistency of the coating.

[0003] However, in actual production, with the frequent changes in product models, the width of the primer (i.e., transfer roller coating) also needs to be adjusted accordingly. However, most existing primer rollers (also known as transfer rollers) adopt a fixed width design, which means that when changing product models, the primer rollers cannot adapt to the new width requirements. This not only lacks flexibility and cannot meet the coating needs of different product models, but also, when the primer width changes, the existing primer rollers often become stagnant because they cannot be adjusted, and may even need to be scrapped. This not only increases production costs but also seriously affects production efficiency, so it needs to be improved. Utility Model Content

[0004] To address the problem that existing transfer rollers cannot adapt to new width requirements, this application provides a transfer roller structure with adjustable primer width.

[0005] The transfer roller structure with adjustable primer width provided in this application adopts the following technical solution:

[0006] An adjustable primer width transfer roller structure includes a roller frame, a roller shaft rotatably mounted on the roller frame, a plurality of primer roller sleeves mounted on the roller shaft, the plurality of primer roller sleeves being sequentially sleeved on the roller shaft, a spacer ring for spacing between adjacent primer roller sleeves, the number of spacer rings between adjacent primer roller sleeves being multiple, and a disassembly and assembly assembly for disassembling and assembling the roller shaft being provided on the roller frame.

[0007] Since most existing primer rollers (also known as transfer rollers) adopt a fixed width design, they cannot adapt to new width requirements when changing products. This not only lacks flexibility and cannot meet the coating needs of different product models, but also makes existing primer rollers sluggish and even need to be scrapped when the primer width changes, which not only increases production costs but also seriously affects production efficiency. By adopting the above technical solution, including a roller frame, the roller shaft is rotatably mounted on the roller frame, and several primer roller sleeves are sequentially mounted on the roller shaft;

[0008] When a product needs to be redesigned to accommodate a wider width, ensure the production line is stopped. Use the disassembly and assembly kit to loosen and remove the primer roller sleeves from the roller shaft. If necessary, a certain number of spacers may also need to be removed to adjust the spacing between the primer roller sleeves. According to the new product width requirements, rearrange the primer roller sleeves and spacers to ensure that the spacing between the primer roller sleeves is uniform and the total width meets the coating requirements of the new product. Install the rearranged primer roller sleeves and spacers back onto the roller shaft in sequence. Use the disassembly and assembly kit to secure the primer roller sleeves. After reinstalling the primer roller sleeves, carefully check the installation of the roller shaft and primer roller sleeves to ensure that there is no looseness or misalignment. Then, formal production can begin.

[0009] With its rollers, primer roller sleeves, and spacers, this structure can easily adapt to the coating requirements of different product models, achieving precise coating control and helping to ensure the uniformity and consistency of the coating. It allows for quick adjustment of the primer width without replacing the entire primer roller, improving the flexibility of the production line, reducing the time required for changeovers, increasing overall production efficiency, and facilitating maintenance. Furthermore, since the primer roller sleeves and spacers are reusable, the adjustment process is relatively simple, avoiding the scrapping of primer rollers due to product changeovers and significantly reducing production costs.

[0010] Optionally, each spacer ring has a positioning boss at one end for positioning, and a positioning recess at the other end for fixing, wherein the positioning boss of the spacer ring is adapted to the positioning recess of the adjacent spacer ring.

[0011] By adopting the above technical solution, the positioning boss is integrally formed at one end of the spacer ring, and the positioning recess is integrally formed at the other end of the spacer ring. Through the setting of the positioning boss and the positioning recess, and the matching design of the positioning boss and the positioning recess, the accurate positioning of the spacer ring during installation is ensured, the installation error is reduced, the connection between the spacers rings is made more stable, and the stability and reliability of the primer roller sleeve are ensured.

[0012] Optionally, the disassembly and assembly assembly includes two bearing assemblies, which are respectively arranged at both ends of the roller shaft along its length. The two ends of the roller shaft are rotatably connected to the two bearing assemblies, and the roller frame has assembly slots on both sides for installing the bearing assemblies.

[0013] By adopting the above technical solution, the disassembly and assembly component includes two bearing assemblies, which are installed in the assembly slots of the roller frame. Through the setting of the bearing assemblies, the bearing assemblies provide stable support for the roller shaft, ensuring that the roller shaft can remain stable and accurate during rotation, while simplifying the disassembly and assembly process and reducing disassembly and assembly time and labor costs.

[0014] Optionally, each of the bearing assemblies is provided with a sliding joint at both ends, the sliding joint being slidably connected within the assembly groove.

[0015] By adopting the above technical solution, the bearing assembly is slidably installed in the assembly groove through the sliding joint; the sliding joint facilitates disassembly and maintenance, helps operators to replace or maintain the roller shaft and primer roller sleeve more quickly, and improves work efficiency.

[0016] Optionally, the top of the roller frame is provided with a limiting plate for restricting the bearing assembly from coming out, and the limiting plate is arranged at the opening of the corresponding assembly slot.

[0017] By adopting the above technical solution, the limiting plate is installed at the opening of the assembly slot. The main function of the limiting plate is to prevent the bearing assembly from falling out of the assembly slot during operation or adjustment, thereby avoiding equipment failure or safety accidents caused by the bearing assembly falling off and ensuring the stable operation of the production line.

[0018] Optionally, the limiting plate is provided with a plurality of fastening bolts for fixing to the roller frame, and the plurality of fastening bolts all penetrate the limiting plate and are threadedly connected to the roller frame.

[0019] By adopting the above technical solution, the limiting plate is installed on the roller frame by fastening bolts; the setting of fastening bolts can ensure a stable connection between the limiting plate and the roller frame, which is firm and reliable and can withstand greater forces and vibrations, further ensuring that the bearing assembly will not fall off due to loosening during operation.

[0020] Optionally, the limiting plate is also provided with a rotating rod for adjusting the height of the roller shaft. The rotating rod passes through the limiting plate and is threadedly connected to the limiting plate. One end of the rotating rod is provided with a knob, and the other end of the rotating rod is rotatably mounted on the top of the bearing assembly.

[0021] By adopting the above technical solution, the rotating rod is threadedly installed on the limiting plate, and the rotating rod is rotatably installed on the top of the bearing assembly; by setting the rotating rod and the knob, the height of the roller shaft can be finely adjusted, which helps to ensure the coating accuracy of the roller shaft during operation, and the operation is simple, simplifying the operation process and reducing the difficulty of operation.

[0022] Optionally, the bearing assembly has a shaft top screw joint for mounting a rotating rod, and the end of the rotating rod is rotatably connected to the shaft top screw joint.

[0023] By adopting the above technical solution, the shaft top screw joint is integrally formed on the top of the bearing assembly, and the screw rod is rotatably installed on the shaft top screw joint. The setting of the shaft top screw joint enhances the connection strength between the bearing assembly and the screw rod, and the screw rod can rotate stably on the shaft top screw joint, making it less prone to loosening or falling off, thus ensuring the stability of the entire structure.

[0024] In summary, this application includes at least one of the following beneficial technical effects:

[0025] With the addition of rollers, primer roller sleeves, and spacers, this structure can easily adapt to the coating requirements of different product models, achieving precise coating control and helping to ensure the uniformity and consistency of the coating. It can quickly adjust the primer width without replacing the entire primer roller, improving the flexibility of the production line, reducing the time required for product changeover, increasing overall production efficiency, and facilitating maintenance. At the same time, since the primer roller sleeves and spacers are reusable, the adjustment process is relatively simple, avoiding the scrapping of primer rollers due to product changeovers and significantly reducing production costs.

[0026] By setting up positioning bosses and positioning recesses, and by designing the cooperation between them, the spacer rings are accurately positioned during installation, reducing installation errors and making the connection between spacers more stable, thus ensuring the stability and reliability of the primer roller sleeve.

[0027] The main function of the limit plate is to prevent the bearing assembly from falling out of the assembly slot during operation or adjustment, thus avoiding equipment failure or safety accidents caused by the bearing assembly falling off and ensuring the stable operation of the production line.

Detailed Implementation

[0032] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0033] This application discloses a transfer roller structure with adjustable primer width. (Refer to...) Figure 1 The adjustable base coat width transfer roller structure includes a roller frame 1, on which a roller shaft 2 is mounted. The roller shaft 2 is arranged along the length of the roller frame 1. In this embodiment, a disassembly assembly 5 is also mounted on the roller frame 1, and the roller shaft 2 is rotatably mounted on the roller frame 1 through the disassembly assembly 5.

[0034] Reference Figure 1 Several primer roller sleeves 3 are mounted on the roller shaft 2. The primer roller sleeves 3 are installed sequentially along the length of the roller shaft 2. In this embodiment, the primer roller sleeves 3 and the roller shaft 2 can be installed and fixed by key connection or other connection methods. A spacer ring 4 is installed between adjacent primer roller sleeves 3. In this embodiment, there are multiple spacer rings 4 between two adjacent primer roller sleeves 3, which can be adjusted according to actual needs.

[0035] Reference Figure 1 and Figure 2 One end of the spacer ring 4 is integrally formed with a positioning boss 41, and the other end of the spacer ring 4 is provided with a positioning recess 42. In this embodiment, the positioning boss 41 of a single spacer ring 4 is adapted to the positioning recess 42 of the adjacent spacer ring 4. At the same time, the primer roller sleeve 3 can also be formed with a recess that matches it. The matching design of the positioning boss 41 and the positioning recess 42 ensures the accurate positioning of the spacer ring 4 during installation, reduces installation errors, makes the connection between the spacer rings 4 more stable, and ensures the stability and reliability of the primer roller sleeve 3.

[0036] Reference Figure 1 and Figure 2 In this embodiment, multiple primer roller sleeves 3 can also be directly connected to each other without the aid of spacers 4. Spacers 4 can be installed on the outer sides of both ends of all primer roller sleeves 3. At the same time, each primer roller sleeve 3 has matching positioning bosses and positioning recesses integrally formed at both ends to facilitate their connection.

[0037] Reference Figure 3 The disassembly and assembly component 5 includes two bearing assemblies 51, which are respectively arranged at both ends of the roller shaft 2. Each bearing assembly 51 contains a bearing for mounting the roller shaft 2. In this embodiment, the bearing can be a ball bearing. Assembly slots 6 are respectively opened on both sides of the roller frame 1, and the two bearing assemblies 51 are respectively installed in the two assembly slots 6. The bearing assembly 51 provides stable support for the roller shaft 2, ensuring that the roller shaft 2 can remain stable and accurate during rotation, while simplifying the disassembly and assembly process and reducing disassembly and assembly time and labor costs.

[0038] Reference Figure 3 Each bearing assembly 51 has an integrally formed sliding joint 7 on both sides. In this embodiment, the sliding joint 7 is recessed and is slidably connected in the assembly groove 6. The sliding joint 7 is easy to disassemble and maintain, which helps operators to replace or maintain the roller shaft 2 and the primer roller sleeve 3 more quickly, thus improving work efficiency.

[0039] Reference Figure 3 Two limiting plates 8 are installed on the top of the roller frame 1, each corresponding to one of the two assembly slots 6. The limiting plates 8 are installed at the openings of the assembly slots 6. Fastening bolts 81 are installed on the limiting plates 8, which pass through the limiting plates 8 and are threaded onto the roller frame 1. In this embodiment, there are multiple sets of fastening bolts 81. The main function of the limiting plates 8 is to prevent the bearing assembly 51 from coming off the assembly slot 6 during operation or adjustment, thus avoiding equipment failure or safety accidents caused by the bearing assembly 51 falling off and ensuring the stable operation of the production line.

[0040] Reference Figure 3 A rotating rod 9 is vertically mounted on the limiting plate 8. A knob 91 is installed at one end of the rotating rod 9, and the other end of the rotating rod 9 passes through the limiting plate 8 and is threadedly connected to the limiting plate 8. In this embodiment, the rotating rod 9 extends toward the bearing assembly 51. The top of the bearing assembly 51 is integrally formed with a shaft top screw joint 10. The end of the rotating rod 9 is rotatably connected to the shaft top screw joint 10. The rotating rod 9 can realize the fine adjustment of the height of the roller shaft 2, which helps to ensure the coating accuracy of the roller shaft 2 during operation. It is also easy to operate, simplifying the operation process and reducing the difficulty of operation. At the same time, the shaft top screw joint 10 enhances the connection strength between the bearing assembly 51 and the rotating rod 9. The rotating rod 9 can rotate stably on the shaft top screw joint 10, and it is not easy to loosen or fall off, ensuring the stability of the entire structure.

[0041] The implementation principle of the adjustable base coating width transfer roller structure in this application embodiment is as follows: When the product needs to be adapted to a different width, ensure that the production line has stopped, use the disassembly and assembly component 5 to loosen and remove the base coating roller sleeve 3 on the roller shaft 2. If necessary, a certain number of spacers 4 need to be removed to adjust the spacing between the base coating roller sleeves 3. According to the new product width requirements, rearrange the base coating roller sleeve 3 and spacers 4 to ensure that the spacing between the base coating roller sleeves 3 is uniform and the total width meets the coating requirements of the new product. Install the rearranged base coating roller sleeve 3 and spacers 4 back onto the roller shaft 2 in sequence, use the disassembly and assembly component 5 to tighten the base coating roller sleeve 3. After reinstalling the base coating roller sleeve 3, carefully check the installation of the roller shaft 2 and the base coating roller sleeve 3 to ensure that there is no looseness or misalignment, and formal production can begin.

[0042] With the configuration of roller 2, primer roller sleeve 3, and spacer 4, this structure can easily adapt to the coating requirements of different product models, achieve precise coating control, help ensure the uniformity and consistency of the coating, and quickly adjust the primer width without replacing the entire primer roller, improving the flexibility of the production line, reducing the time required for product changeover, improving overall production efficiency, and being easy to maintain. At the same time, since the primer roller sleeve 3 and spacer 4 are reusable, the adjustment process is relatively simple, avoiding the scrapping of the primer roller due to product changeover, and significantly reducing production costs.

[0043] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
