[0002] A lithium battery separator production line refers to a series of equipment and processes used to produce lithium battery separators. The separator is a crucial component of a lithium battery; it isolates the positive and negative electrodes, preventing short circuits, while allowing lithium ions to pass through, enabling the battery to charge and discharge. The quality and performance of the separator directly affect the safety, cycle life, and energy density of the lithium battery.

[0003] Some fixed coating blade hoppers now have foam baffles on both sides to prevent foam leakage from the hopper cavity. However, since their installation position is fixed, foam leakage can occur if the gap between them and the coating roller is too large. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an adjustable foam baffle for coating.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: An adjustable foam baffle for coating includes a baffle assembly installed on both sides of a coating blade box. Movable cavities are formed on the side walls of the coating blade box for the baffle assembly to move. Guide components are laterally arranged on both side walls of the coating blade box above the movable cavities. An electric cylinder connecting frame is located at the top of the coating blade box, with both ends connected to the guide components. The baffle assembly is connected to the guide components. The electric cylinder connecting frame is driven linearly by a drive component located at the top of the coating blade box.

[0006] Furthermore, in a preferred configuration, the baffle assembly includes a baffle connecting plate, a foam baffle body is mounted on one side surface of the baffle connecting plate, the foam baffle body is movable in the baffle movable cavity, and the foam baffle body is mounted on the baffle connecting plate by a fixing component.

[0007] In addition, a preferred structure is that the top of the baffle connecting plate is provided with a baffle connecting frame, which is used to connect to the top guide assembly.

[0008] Furthermore, in a preferred configuration, the guide assembly includes a slide rail on which a connecting slider is slidably fitted, the connecting slider being used to connect the baffle connecting frame and the electric cylinder connecting frame.

[0009] Furthermore, in a preferred configuration, the electric cylinder connecting frame includes a push plate, a piston rod connecting plate is provided in the middle of the push plate, the piston rod connecting plate is used to connect the drive assembly, and side connecting frames are symmetrically installed on the bottom surfaces of both ends of the push plate, the side connecting frames are used to connect with the connecting slider.

[0010] Furthermore, in a preferred configuration, the drive assembly includes a servo electric cylinder mounted on top of the coating blade box, with a piston rod connected to the output end of the servo electric cylinder, the piston rod being connected to a piston rod connecting plate.

[0011] The beneficial effects of this utility model are as follows: This utility model uses a servo electric cylinder of the drive component to push the piston rod, which in turn drives the electric cylinder connecting frame to drive the guide component, including the slide rail and connecting slider, to move linearly. This causes the baffle components on both sides to extend and retract synchronously, and the foam baffle plate moves within the baffle movable cavity. The gap between the foam baffle plate and the coating roller can be adjusted in real time, completely sealing the foam leakage path. The foam baffle plate is detachably connected to the baffle connecting plate through fixing components such as bolts. Different sizes of baffles can be replaced to adapt to coating rollers of different diameters, improving the versatility of the equipment. Attached Figure Description

Detailed Implementation

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0015] Reference Figure 1-5An adjustable foam baffle for coating includes a baffle assembly (2). The baffle assembly (2) is installed on both sides of a coating scraper box (1). A baffle movable cavity (11) is provided on both side walls of the coating scraper box (1). The baffle movable cavity (11) is used for the movement of the baffle assembly (2). A guide assembly (3) is provided horizontally on both side walls of the coating scraper box (1) above the baffle movable cavity (11). An electric cylinder connecting frame (4) is provided on the top of the coating scraper box (1). Both ends of the electric cylinder connecting frame (4) are connected to the guide assembly (3). The baffle assembly (2) is connected to the guide assembly (3). The electric cylinder connecting frame (4) is pushed to move linearly by a drive assembly (5) provided on the top of the coating scraper box (1). The drive assembly (5) enables the foam baffle plates 21 on both sides to be adjusted synchronously.

[0016] In addition, the baffle assembly (2) includes a baffle connecting plate (22), a foam baffle plate body (21) is installed on one side surface of the baffle connecting plate (22), the foam baffle plate body (21) is set in the baffle movable cavity (11) and the foam baffle plate body (21) is installed on the baffle connecting plate (22) by a fixing component (23). The foam baffle plate body 21 is used to seal the coating scraper box 1 to prevent foam from leaking from both sides.

[0017] Meanwhile, a baffle connecting frame (24) is provided on the top of the baffle connecting plate (22). The baffle connecting frame (24) is used to connect to the top guide component (3). The baffle connecting frame 24 is used to achieve linear movement through the guide component 3.

[0018] Furthermore, the guide assembly (3) includes a slide rail (31), on which a connecting slider (32) is slidably fitted. The connecting slider (32) is used to connect the baffle connecting frame (24) and the electric cylinder connecting frame (4). The connecting slider 32 cooperates with the slide rail 31 to realize the linear movement of the electric cylinder connecting frame 4 and the baffle assembly 2.

[0019] Among them, the electric cylinder connecting frame (4) includes a push plate (42), a piston rod connecting plate (41) is provided in the middle of the push plate (42), the piston rod connecting plate (41) is used to connect the drive assembly (5), and side connecting frames (43) are symmetrically installed on the bottom surface of both ends of the push plate (42). The side connecting frames (43) are used to connect with the connecting slider (32). The drive assembly (5) includes a servo electric cylinder (52), the servo electric cylinder (52) is installed on the top of the coating scraper box (1), and a piston rod (51) is assembled and connected to the output end of the servo electric cylinder (52). The piston rod (51) is used to connect to the piston rod connecting plate (41), and the piston rod (51) is used to push the push plate 42 to move back and forth linearly.

[0020] In this embodiment, by moving the foam baffle plates 21 on both sides, the foam baffle plates 21 can be adjusted to fit the coating roller, ensuring a smaller gap between the coating roller and the coating doctor blade box 1. The servo electric cylinder 52 drives the piston rod 51 to extend or retract, so that the push plate 42 can drive the side connecting frames 43 on both sides to drive the connecting slider 32 to move on the slide rail 31. After the connecting slider 32 moves, it drives the bottom baffle connecting frame 24, thereby realizing the movement of the foam baffle plate 21 within the baffle movable cavity 11, adjusting its extension distance. Furthermore, the foam baffle plate 21 can be removed from the baffle connecting plate 22 by disassembling the fixing component 23, and different foam baffle plates 21 can be replaced to adapt to coating rollers of different diameters.

This causes the two side baffle assemblies 2 to extend and retract synchronously, and the foam baffle plate 21 moves within the baffle movable cavity 11. The gap with the coating roller can be adjusted in real time to completely block the foam leakage path. The foam baffle plate 21 is detachably connected to the baffle connecting plate 22 by a fixing component 23, such as bolts.
