Description

Technical Field

[0001] This utility model relates to the field of electrode production and processing, specifically to an electrode calendering device and a coating roller press. Background Technology

[0002] Foil, as a special metallic material, is widely used in industries such as electronics, electrical appliances, packaging, aviation, aerospace, and automobiles. During processing, foil undergoes multiple winding and rolling processes. After rolling, the foil's thickness decreases, its surface becomes smoother, and its strength, plasticity, and gloss are all improved. However, existing rolling equipment has limitations when processing multiple foils. To improve processing efficiency, traditional equipment is typically equipped with multiple rolling rollers to process multiple foils simultaneously. However, this design cannot independently adjust the rolling pressure when dealing with foils of different materials, thicknesses, or widths. Different materials have significantly different rolling requirements; for example, harder materials may require greater rolling force, while thinner materials require more precise pressure control to avoid damage or deformation. Without the ability to independently adjust the pressure of each rolling roller, the equipment often struggles to meet these differentiated needs, leading to unstable foil rolling quality and even defects such as strip breakage and wrinkling, thus affecting overall processing efficiency and product yield. Utility Model Content

[0003] The main purpose of this invention is to provide an electrode tab calendering device and a coating roller press to solve the problem that the calendering force of each calendering roller cannot be adjusted individually in the prior art.

[0004] To achieve the above objectives, according to one aspect of the present invention, a tab calendering apparatus is provided, comprising a base, a running roller, and a calendering assembly for calendering foil. The running roller is rotatably connected to the base. A gap is provided between the running roller and the calendering assembly for the foil to pass through. The gap forms multiple processing areas along the axial direction. Multiple foils are processed in different processing areas. There are multiple calendering assemblies, each forming a different processing area with the running roller. Each calendering assembly includes a calendering roller group and a calendering drive component. The calendering drive component is drivenly connected to the calendering roller group and drives the calendering roller group to approach the running roller to calender the foil. The calendering drive component of each calendering assembly operates independently.

[0005] Furthermore, the tab rolling apparatus also includes a transverse frame and multiple transverse drive components. The transverse frame is connected to the base, and each rolling assembly is movably mounted on the transverse frame. Each transverse drive component is drivenly connected to the rolling assembly and drives the transverse drive component to move on the transverse frame.

[0006] Furthermore, the lateral movement direction of the calendering assembly is perpendicular to the foil conveying direction.

[0007] Furthermore, a transverse movement structure is provided between the calendering assembly and the transverse movement frame. The transverse movement structure includes a rack and multiple gears. The rack is mounted on the transverse movement frame. Each calendering assembly has a gear, and each gear meshes with the rack. The gears can move laterally relative to the rack and drive the calendering assembly to move laterally.

[0008] Furthermore, the calendering roll assembly includes calendering rolls and multiple adhesive pressing rolls. Adhesive pressing rolls are provided on both sides of each calendering roll. The adhesive pressing rolls and calendering rolls are arranged along the axial direction of the running rolls. Both the calendering rolls and adhesive pressing rolls are driven and connected to the calendering drive component, which drives the calendering rolls and adhesive pressing rolls to move synchronously. The calendering assembly also includes multiple adhesive pressing drive components, each of which is driven and connected to different adhesive pressing rolls and drives the adhesive pressing rolls to press the foil.

[0009] Furthermore, the tab calendering device also includes a tension adjustment assembly, which includes a tension roller and an adjustment roller. The tension roller is movably connected to the base and detects the tension of the foil. The adjustment roller is movably connected to the base, and the foil passes around the tension roller and the adjustment roller, with the adjustment roller being closer to the running roller than the tension roller.

[0010] Furthermore, there are multiple tension adjustment components, and tension adjustment components are symmetrically arranged on both sides of the running roller.

[0011] Furthermore, the tab calendering apparatus also includes a swing roller assembly for adjusting the foil tension. Along the foil conveying direction, the swing roller assembly is located away from the running roller relative to the tension adjusting assembly and is downstream of the tension adjusting assembly.

[0012] Furthermore, the tab calendering apparatus also includes a support roller, which is located above the running roller and contacts and presses against the running roller.

[0013] According to another aspect of the present invention, a coating roller press is provided, including the above-described tab calendering device.

[0014] By applying the technical solution of this utility model, the tab calendering device can simultaneously process multiple foils by setting up multiple processing areas and multiple calendering drive components. It can also drive the calendering roll groups corresponding to the multiple processing areas separately, thereby applying different calendering forces to the multiple foils. The calendering force of the foil in each processing area can be individually adjusted to the optimal state, thus improving the processing quality of the foils. Specifically, on the one hand, multiple processing areas are formed between the running roller and the multiple calendering roll groups to facilitate the simultaneous processing of multiple foils, thereby improving processing efficiency. On the other hand, each calendering roll group is equipped with an independent calendering drive component, allowing each calendering roll group to be driven independently. This means that when the processing requirements of the foils in the multiple processing areas are different, the corresponding calendering roll group can adjust the calendering force accordingly through the calendering drive component, ensuring that the calendering force in each processing area is adjusted to the optimal state during foil processing, thereby improving the processing quality of the foils. Furthermore, the tab calendering device of this embodiment has a simple structure, is easy to adjust, has a small size, saves factory production space, and has a low cost.

[0022] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0023] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0024] In this utility model, unless otherwise stated, directional terms such as "upper," "lower," "top," and "bottom" are generally used in relation to the direction shown in the accompanying drawings, or in relation to the vertical, perpendicular, or gravitational direction of the component itself; similarly, for ease of understanding and description, "inner" and "outer" refer to the inner and outer contours of each component itself, but the above directional terms are not used to limit this utility model.

[0025] To address the problem that the calendering force of each calendering roll cannot be adjusted independently in the prior art, this utility model provides an electrode tab calendering device and a coating roll press, wherein the coating roll press includes the electrode tab calendering device described below.

[0026] like Figures 1 to 4 The illustrated tab calendering apparatus includes a base 10, a running roller 20, and a calendering assembly 30 for calendering foil 90. The running roller 20 is rotatably connected to the base 10. A gap is provided between the running roller 20 and the calendering assembly 30 for the foil 90 to pass through. The gap forms multiple processing areas along the axial direction. Multiple foils 90 are processed in different processing areas. There are multiple calendering assemblies 30, and each calendering assembly 30 forms a different processing area with the running roller 20. Each calendering assembly 30 includes a calendering roller group 31 and a calendering drive. The calendering drive is driven to the calendering roller group 31 and drives the calendering roller group 31 to approach the running roller 20 to calender the foil 90. The calendering drive of each calendering assembly 30 operates independently.

[0027] This embodiment enables the tab calendering device to process multiple foils 90 simultaneously by setting up multiple processing areas and multiple calendering drive components. It can also drive the calendering roll groups 31 corresponding to each processing area, thereby applying different calendering forces to the multiple foils 90. The calendering force of the foil 90 in each processing area is individually adjusted to the optimal state, thus improving the processing quality of the foils 90. Specifically, on the one hand, multiple processing areas are formed between the running roller 20 and the multiple calendering roll groups 31 to facilitate the simultaneous processing of multiple foils 90, thereby improving processing efficiency; on the other hand... Each calendering roll group 31 is equipped with an independent calendering drive unit, so that each calendering roll group 31 can be driven independently. This allows the calendering roll group 31 to adjust the calendering force according to the calendering drive unit when the processing requirements of the foil 90 in multiple processing areas are different. This ensures that the calendering force in each processing area can be adjusted to the optimal state when processing the foil 90, thereby improving the processing quality of the foil 90. At the same time, the tab calendering device in this embodiment has a simple structure, is easy to adjust, has a small size, saves factory production space, and has a low cost.

[0028] It should be noted that the running roller 20 in this embodiment has a cylindrical shape, and the axial direction in this embodiment refers to the axial direction of the running roller 20, which is the direction in which the multiple processing areas are arranged. Figure 3 In the left and right directions. In this embodiment, the running roller 20 drives the steel roller to rotate through a servo motor and a planetary reducer, which indirectly drives the conveying of the foil 90 and, together with the calendering roller 311, performs calendering and rolling of the foil 90.

[0029] In this embodiment, the tab calendering apparatus further includes a transverse frame 40 and multiple transverse drive members 50. The transverse frame 40 is connected to the base 10, and each calendering assembly 30 is movably mounted on the transverse frame 40. Each transverse drive member 50 is drivenly connected to the calendering assembly 30 and drives the transverse drive member 50 to move on the transverse frame 40, thereby enabling the calendering assembly 30 to move along the axial direction of the running roller 20, thus changing the position of the processing area. This allows the tab calendering apparatus to be applicable to foils 90 of different widths, thereby improving its flexibility and expanding its application range. Specifically, in this embodiment, the transverse frame 40 is located below the calendering assembly 30, and the bottom of the calendering assembly 30 cooperates with the transverse frame 40, thereby realizing the movement of each calendering assembly 30 relative to the transverse frame 40. When the lateral drive 50 drives the calendering assembly 30 to move, the position of the processing area between the calendering assembly 30 and the running roller 20 moves accordingly, thereby changing the distance between each processing area. This allows for the processing of foils 90 with different widths. In this way, the tab calendering device can accommodate different incoming material widths and multiple blank areas. Each lateral drive 50 can drive each calendering assembly 30 to achieve individual lateral displacement adjustment. Combined with the aforementioned individual adjustment of the calendering pressure of each calendering roller group 31 on the foil 90, this meets the multi-functional technical requirements of complex incoming materials and multi-line shared production, thereby improving productivity. The blank area refers to the area between adjacent processing areas.

[0030] In this embodiment, the lateral movement direction of the calendering assembly 30 is perpendicular to the conveying direction of the foil 90. This allows the processing area to move along the axial direction of the running roller 20 as the calendering assembly 30 moves, satisfying the processing requirements of foils 90 with different widths while ensuring effective cooperation between the calendering roller group 31 and the running roller 20, thereby guaranteeing the processing quality of the foil 90. Since the conveying direction of the foil 90 in this embodiment is perpendicular to the axial direction of the running roller 20, the lateral movement direction of the calendering assembly 30 is also the axial direction of the running roller 20.

[0031] like Figure 4As shown, in this embodiment, a transverse movement structure is provided between the calendering assembly 30 and the transverse movement frame 40. The transverse movement structure includes a rack 41 and multiple gears 32. The rack 41 is disposed on the transverse movement frame 40. Each calendering assembly 30 has a gear 32, and each gear 32 meshes with the rack 41. The gear 32 can move laterally relative to the rack 41 and drive the calendering assembly 30 to move laterally, thereby enabling each calendering assembly 30 to move laterally relative to the transverse movement frame 40, thereby adjusting the size of each processing area to move the foil 90 laterally to the position where it needs to be calendered, thus adapting to different foil widths. Specifically, in this embodiment, the rack 41 is disposed on the upper surface of the transverse frame 40, extending axially along the running roller 20. Each calendering assembly 30 is also arranged axially along the running roller 20. A gear 32 is disposed at the bottom of each calendering assembly 30, and a transverse drive 50 is disposed on one side of the gear 32. When the transverse drive 50 is driven, the gear 32 rotates, thereby driving the calendering assembly 30 to move along the extension direction of the rack 41, thus achieving transverse movement of the processing area. In this embodiment, the transverse drive 50 is disposed on one side of the gear 32 and is configured as a handle, allowing manual operation by the operator. The handle is cylindrical and coaxial with the gear 32, with patterns on its circumferential surface for ease of operation. Of course, depending on the actual situation, such as when the width of the foil 90 needs frequent adjustment, and the processing area needs frequent adjustment accordingly, the transverse drive 50 can also be configured as a servo motor or similar device to drive the gear 32, thereby reducing the operator's workload and improving the calendering efficiency of the foil 90.

[0032] In this embodiment, a guide rail is provided on the upper surface of the transverse frame 40, and the extension direction of the guide rail is consistent with the extension direction of the rack 41. A slider is provided at the bottom of the calendering assembly 30, and each calendering assembly 30 has its own slider at its bottom. Each slider cooperates with the guide rail and can move along the extension direction of the guide rail, thereby providing guidance for the lateral movement of the calendering assembly 30 to ensure that the calendering assembly 30 moves axially along the running roller 20, thereby ensuring the effective cooperation between the calendering assembly 30 and the running roller 20, and thus ensuring the processing quality of the foil 90. Optionally, a locking member can be provided on one side of the slider. The locking member and the slider are movably configured. The locking end of the locking member passes through the mounting hole of the slider and can abut against the guide rail. In this way, when the calendering assembly 30 needs to be moved laterally, the locking end passes through one side of the slider but does not abut against the guide rail, thus facilitating the smooth movement of the calendering assembly 30. When the calendering assembly 30 is moved laterally into place, the locking end passes through the slider and abuts against the guide rail, thereby locking the calendering assembly 30 to the guide rail and preventing the movement of the calendering assembly 30 from affecting the processing quality when the electrode calendering device is processing foil 90.

[0033] In this embodiment, the calendering roll group 31 includes a calendering roll 311 and a plurality of adhesive rollers 312. Adhesive rollers 312 are provided on both sides of each calendering roll 311. The adhesive rollers 312 and the calendering roll 311 are arranged along the axial direction of the running roll 20. The calendering roll 311 and the adhesive rollers 312 are both driven and connected to the calendering drive component. The calendering drive component drives the calendering roll 311 and the adhesive rollers 312 to move synchronously, so that the calendering roll group 31 can move closer to and further away from the running roll 20, thereby adjusting the calendering pressure of the foil 90 in each processing area. Specifically, in this embodiment, a pressure roller 312 is provided on each side of the calendering roller 311 along its axial direction. Both the calendering roller 311 and the pressure roller 312 are cylindrical, and their circumferential surfaces mate with the circumferential surface of the running roller 20, thereby forming a processing area between the circumferential surfaces. The foil 90 passes through the circumferential surfaces, so that when the calendering drive unit drives the calendering roller group 31 to approach and move away from the running roller 20, the pressure of the calendering roller 311 and the pressure roller 312 on the foil 90 can be adjusted simultaneously to improve the processing efficiency and quality of the foil 90. Of course, depending on the actual situation, the calendering drive unit can also drive only the calendering roller 311, with a separate drive unit for the pressure roller 312. When calendering the foil 90, the calendering roller 311 and the pressure roller 312 can be driven to approach and compress the foil 90 simultaneously. Optionally, the calendering drive unit can be a hydraulic cylinder to provide calendering force to the calendering roller 311.

[0034] like Figure 3 , Figure 4 As shown, the calendering roll group 31 in this embodiment is provided with three groups, thereby forming three processing areas. The same or different foil materials 90 can be processed in the three processing areas. According to actual needs, the number of calendering roll groups 31 can be increased or decreased, and the same number of calendering drive components can be matched to the calendering roll groups 31 accordingly, so that the calendering force of each processing area can be adjusted independently.

[0035] The calendering assembly 30 in this embodiment also includes multiple adhesive pressing drive components. Each adhesive pressing drive component is driven and connected to a different adhesive pressing roller 312, and drives the adhesive pressing roller 312 to press the foil 90, thereby adjusting the pressure applied by the adhesive pressing roller 312 to the foil 90, preventing the foil 90 from slipping during the calendering process and avoiding damage to the foil 90. Specifically, each adhesive pressing roller 312 in this embodiment is provided with an adhesive pressing drive component, so that each adhesive pressing roller 312 can be adjusted independently to adjust the distance between the adhesive pressing roller 312 and the running roller 20, thereby applying different pressures to the foil 90 in different processing areas and preventing the foil 90 from slipping and wrinkling. Of course, since the two adhesive rollers 312 on both sides of the same calendering roller 311 belong to the same calendering roller group 31 and are located in the same processing area, calendering the same foil 90, the two adhesive rollers 312 within the same calendering roller group 31 can also be configured with the same adhesive pressing drive. In this way, one adhesive pressing drive drives the two adhesive rollers 312 to simultaneously approach and move away from the running roller 20, applying the same pressure to the foil 90. Optionally, the adhesive pressing drive can be a dual-axis hydraulic cylinder, thereby providing pressure to the adhesive rollers 312.

[0036] In this embodiment, the tab calendering device further includes a tension adjustment component 60, which includes a tension roller 61 and an adjustment roller 62. The tension roller 61 is movably connected to the base 10 and detects the tension of the foil 90. The adjustment roller 62 is movably connected to the base 10, and the foil 90 passes around the tension roller 61 and the adjustment roller 62. The adjustment roller 62 is closer to the running roller 20 than the tension roller 61, thereby improving the processing quality of the foil 90. In this embodiment, the tension roller 61 and the adjustment roller 62 are also cylindrical, and their axial direction is consistent with the axial direction of the running roller 20 to facilitate the conveying of the foil 90. In this way, the tension adjustment component 60 can detect the tension of the foil 90 in real time and adjust the angle at which the foil 90 enters and exits the calendering roller 311, thereby ensuring the stability of the tension of the foil 90 during the calendering process and avoiding damage to the foil 90 or poor calendering effect caused by uneven tension.

[0037] like Figure 1 , Figure 2As shown, in this embodiment, there are multiple tension adjustment components 60, and tension adjustment components 60 are symmetrically arranged on both sides of the running roller 20. This ensures that the tension on both sides of the foil 90 is consistent during the calendering process, thereby further improving the uniformity and stability of the calendering of the foil 90 and avoiding excessive tension on one side that could cause the foil 90 to shift or wrinkle. Specifically, there are two tension adjustment components 60 in this embodiment, both of which are arranged adjacent to the running roller 20. Before calendering the foil 90, the tension roller 61 detects the tension on the foil 90 so that the adjustment roller 62, located downstream of the tension roller 61 and upstream of the running roller 20, can adjust the angle at which the foil 90 enters the calendering roller 311. After the foil 90 has completed calendering by the calendering roller 311, it passes through another adjustment roller 62 to adjust the angle at which the foil 90 is conveyed out of the calendering roller 311. Then it passes through another tension roller 61 to detect the tension data of the calendered foil 90, thereby enabling the detection and rapid adjustment of the tension of the foil 90.

[0038] In this embodiment, the tab calendering apparatus further includes a swing roller assembly 70 for adjusting the tension of the foil 90. Along the conveying direction of the foil 90, the swing roller assembly 70 is located away from the running roller 20 relative to the tension adjusting assembly 60 and downstream of the tension adjusting assembly 60, thereby further adjusting the tension of the foil 90 to ensure that the foil 90 reaches an ideal tension state after calendering. The swing roller assembly 70 in this embodiment includes a cylindrical swing roller, the axial direction of which is aligned with the axial direction of the running roller 20. When the foil 90 is conveyed from the tension adjusting assembly 60 to the swing roller, the swing roller assembly 70 can further adjust the tension state of the foil 90 based on the tension detected by the tension roller 61, thereby adjusting the calendered foil 90 to a suitable tension.

[0039] In this embodiment, the tab calendering device further includes a support roller 80, which is located above the running roller 20 and contacts and presses against the running roller 20. This enhances the load-bearing capacity of the running roller 20, ensuring its stability and balance during operation, thereby ensuring the stable transport of the foil 90 and guaranteeing its processing quality. The support roller 80 in this embodiment is also cylindrical, with its axial direction the same as the running roller 20. Furthermore, the outer diameter of the support roller 80 is larger than that of the running roller 20, thus effectively supporting the running roller 20 and preventing deformation and bending during the calendering process.

[0040] In this embodiment, the electrode rolling device also includes an auxiliary roller to assist the foil 90 in its conveying direction path, making the conveying of the foil 90 smoother.

[0041] The electrode calendering device in this embodiment takes the calendering of electrode tabs as an example. The operation process is as follows: When the foil 90 enters the electrode calendering device from the previous process, it first enters the tension roller 61 and the tension of the foil 90 is detected in the pre-calendering stage. Then it enters the adjusting roller 62. The running roller 20 is equipped with adjusting rollers 62 at the front and rear, which can adjust the running angle of the foil 90 entering and exiting the calendering roller group 31. Then the foil 90 enters the calendering assembly 30 for the calendering process. The foil 90 passes through the middle of the running roller 20 and the calendering roller 311. The calendering drive applies pressure to the calendering roller group 31 to calender the electrode tabs. The process requirements for electrode calendering in each processing area can be achieved by adjusting the pressure of each calendering drive on the calendering roller group 31. The calendering roller 311 is equipped with adjusting rollers 62 at the front and rear, respectively. Equipped with a pressure roller 312 and a pressure drive, the pressure drive pushes the pressure roller 312 to press the foil 90 during the calendering process, preventing the foil 90 from slipping. The lateral movement structure can move the calendering assembly 30 to the position where the foil 90 needs to be calendered. The number of calendering assemblies 30 can be matched according to the number of calendering strips. The calendered foil 90 enters the tension adjustment assembly 60 downstream of the calendering roller 311 and then enters the swing roller assembly 70. It is then conveyed to the next process through the auxiliary roller. The tension adjustment assembly 60 downstream of the calendering roller 311 is used to detect the tension data of the calendered foil 90. The swing roller assembly 70 adjusts the foil 90 to a suitable tension based on the tension data of the foil 90 detected by the tension roller 61, thus completing the entire tab calendering process.

[0042] It should be noted that "multiple" in the above embodiments refers to at least two.

[0044] 1. Solve the problem that the calendering force of each calendering roll cannot be adjusted individually in the existing technology;

[0045] 2.
