Description

Technical Field

[0001] This utility model relates to the field of positive electrode processing technology, and in particular to a coating device for a positive electrode preparation apparatus. Background Technology

[0002] Positive electrode coating refers to the process of uniformly coating a positive electrode slurry (composed of positive electrode active materials, binders, and conductive agents, etc.) onto a positive electrode current collector. After coating, the wet coating and current collector are dried under a hot airflow as they slowly pass through a drying channel to remove organic solvents, thus forming a positive electrode sheet.

[0003] Before coating, the spacing of the coating rollers on the coater needs to be adjusted. However, in the existing technology, many coating rollers are adjusted manually, which is not precise enough. Furthermore, the installation and disassembly of the coating rollers are inconvenient and not conducive to later maintenance.

[0004] Therefore, we propose a coating device for a positive electrode preparation apparatus. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies where many coating rollers are manually adjusted, resulting in imprecise adjustments, inconvenient installation and disassembly of the coating rollers, and difficulties in subsequent maintenance. Therefore, this invention proposes a coating device for a positive electrode preparation apparatus.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A coating device for a positive electrode preparation apparatus includes:

[0008] The mounting base has two symmetrically arranged guide plates fixed on one side, and the same slide is slidably connected between the two guide plates. A first coating roller is provided between the inner walls of the two sides of the slide. Two symmetrically arranged adjustment grooves are opened on one side of the slide. An adjustment block is slidably connected in each of the two adjustment grooves, and a second coating roller is provided between the two adjustment blocks.

[0009] An adjustment mechanism is provided at the top of the slide block for adjusting the height of the second coating roller.

[0010] A limiting mechanism is provided at the top of the mounting base and is used to limit the sliding block.

[0011] In one possible design, the adjustment mechanism includes a motor fixed to the top of the slide block, with one end of the motor output shaft extending into the adjustment groove and fixed with a screw threaded through the adjustment block.

[0012] In one possible design, the limiting mechanism includes a slide groove, which is formed at the top of the mounting base. A limiting plate is slidably connected inside the slide groove. The limiting plate and the slide base cooperate with each other. A spring is fixed between one side of the limiting plate and one side of the inner wall of the slide groove.

[0013] In one possible design, a lever is fixed to the surface of the limiting plate, and two stop bars are fixed to the top of the mounting base, with the stop bars and levers cooperating with each other.

[0014] In one possible design, two positioning blocks are fixed on the bottom surface of the mounting base, and two positioning grooves are opened on the bottom of the slide, with the positioning blocks and positioning grooves cooperating.

[0015] In one possible design, both the top of the guide plate and the top of the positioning block are chamfered.

[0016] In one possible design, two mounting holes are provided on both outer walls of the mounting base.

[0017] In one possible design, inclined plates are fixed on both inner walls of the mounting base, and a paint baffle is slidably connected between the two inclined plates. Two first set screws are threaded through the surface of the paint baffle, and the first set screws abut against the inclined plates. Two side baffles are slidably connected to the outer wall of the paint baffle, and second set screws are threaded through the surface of the side baffles, and the second set screws abut against the paint baffles.

[0018] In this application, when adjusting the height of the first coating roller, the controller starts the motor, the motor drives the screw to rotate, the screw drives the adjusting block to slide along the adjusting groove, thereby changing the height of the first coating roller, which is more precise than manual adjustment;

[0019] During maintenance, the limit plate is moved by using the toggle block to disengage it from the slide block, thus releasing the limit on the slide block. Then, the slide block is removed from the guide plate, making it easier for maintenance personnel to maintain the first coating roller and other related structures. After maintenance, the slide block is reinstalled on the guide plate, and then the toggle block is released. The spring pushes the limit plate back to its original position, so that the limit plate limits the slide block again.

[0020] Beneficial effects: In this utility model, the coating device of the positive electrode preparation apparatus can automatically adjust the height of the first coating roller through the setting of multiple structures such as motor, screw and adjusting block, so that the adjustment is more precise;

[0021] In this utility model, the coating device of the positive electrode preparation apparatus, through the setting of multiple structures such as sliding base, guide plate and limiting plate, can facilitate people to quickly install and disassemble the structure, which provides convenience for later maintenance;

[0022] In this invention, the height of the first coating roller can be automatically adjusted, making the adjustment more precise. This allows for quick and easy installation and disassembly of the structure, and provides convenience for later maintenance. Attached Figure Description
