[0036] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0037] like Figures 1-4 As shown, the transfer coating machine baffle device of this utility model includes a carrier frame 1, a baffle 2, a first fixing bolt 3, and a second fixing bolt 4.

[0038] like Figures 1-4 As shown, the carrier 1 is used to connect the coating machine; multiple baffles 2 are arranged in parallel, and one end of the baffle 2 is slidably engaged with the carrier 1 and can be positioned relative to the carrier 1; the end of the baffle 2 away from the carrier 1 is provided with an arc-shaped groove 201 and fits into the coating machine roller group.

[0039] See Figure 4 The coating machine is equipped with a horizontal plate 200. When in use, the baffle 2 abuts against the roller group 100 of the coating machine through the arc-shaped groove 201. The upper part of the horizontal plate 200 is used to place the slurry bucket. When the slurry bucket supplies slurry, the slurry will fall onto the horizontal plate 200. The electrode substrate 300 is conveyed by the roller group 100 and is located between two adjacent baffles 2. When the slurry spreads on the horizontal plate 200 and contacts the electrode substrate 300, the coating of the slurry is achieved as the electrode substrate 300 is conveyed.

[0040] To facilitate control of the coating width of the slurry, a carrier 1 is provided. The carrier 1 is used to connect the horizontal plate 200 and slide the baffle 2. By sliding and adjusting the baffle 2, the coating width of the electrode substrate 300 can be adjusted.

[0041] like Figure 2 As shown, the baffle 2 includes a steel structural member 21 and a rigid plastic member 22, wherein the steel structural member 21 is slidably connected to the carrier frame 1; the rigid plastic member 22 is connected to the steel structural member 21 and faces the electrode substrate;

[0042] As described above, the baffle 2 includes two parts: a steel structural component 21 and a rigid plastic component 22. The steel structural component 21 is used to connect the carrier frame 1 and to fix the rigid plastic component 22. The rigid plastic component 22 is used to contact the horizontal plate 200 and the roller group 100 to prevent the slurry from overflowing.

[0043] In some embodiments, the rigid plastic part 22 is connected to the steel structure part 21 by fasteners to facilitate the replacement of the rigid plastic part 22.

[0044] like Figure 2As shown, a portion of the steel structural member 21 extends along the edge of the rigid plastic member 22;

[0045] As described above, the extended portion of the steel structural component 21 corresponds to the length side of the rigid plastic component 22, thereby ensuring the structural strength of the rigid plastic component 22 and reducing the probability of damage.

[0046] like Figure 3 As shown, the carrier 1 includes a fixed frame 11 and a sliding rod 12. There are two fixed frames 11 arranged opposite each other, and the fixed frames 11 have a U-shaped structure. The sliding rod 12 is arranged between the two fixed frames 11, and the sliding rod 12 is away from the opening end of the fixed frame 11. The baffle 2 is slidably engaged with the sliding rod 12.

[0047] As described above, the fixed frame 11 is configured as a U-shaped structure, which is used to snap the horizontal plate 200. Then, the baffle 2 is slidably installed on the slide rod 12 and the baffle 2 is made to abut against the surface of the horizontal plate 200. In this way, the baffle 2 can slide and adjust between the two fixed frames 11 along the slide rod 12 to control the coating width of the slurry and prevent the slurry from overflowing.

[0048] like Figure 1 and Figure 3 As shown, the fixed frame 11 is parallel to the baffle 2; as described above, in order to ensure the compactness of the structure, the fixed frame 11 and the baffle 2 are set as parallel structures.

[0049] like Figure 1 and 3 As shown, the slide bar 12 is perpendicular to the baffle 2, and the surface of the slide bar 12 is provided with scale.

[0050] As described above, the slide rod 12 is perpendicular to the baffle 2 and the fixed frame 11, thus forming a U-shaped structure with the slide rod 12 and the fixed frame 11. The baffle 2 is located inside the opening of the U-shaped structure, and the slide rod 12 can be marked on the side away from the opening, so that the distance between two adjacent baffles 2 can be adjusted according to the markings.

[0051] like Figure 2 As shown, the steel structure component 21 includes a first plate 211 and a second plate 212. The first plate 211 has a slot 202 for engaging the carrier frame 1. The second plate 212 is connected to the first plate 211 and fits against the edge of the rigid plastic component 22. The first fixing bolt 3 passes through the first plate 211 and is threadedly connected to the carrier frame 1.

[0052] As described above, in the steel structural component 21, the first plate 211 has a slot 202 to facilitate the connection of the slide rod 12 of the carrier frame 1, and the second plate 212 is an extension component used to fit the edge of the hard plastic component 22 to achieve structural reinforcement of the hard plastic component 22.

[0053] When fixing the baffle 2, multiple bolt holes are made on the slide rod 12. After the baffle 2 is adjusted into place, the first fixing bolt 3 passes through the first plate 211 and is connected and fixed with the bolt holes.

[0054] like Figure 2 As shown, the portion of the first plate 211 located on the side of the card slot 202 away from the hard plastic part 22 has a larger volume than the portion located on the other side of the card slot 202.

[0055] As described above, the first plate 211 is divided by the slot 202. The side of the plate that is far from the hard plastic part 22 has a larger volume, while the other side has a smaller volume. In this way, after the baffle 2 is connected to the carrier 1, the weight on both sides is more even, which can reduce the resistance during sliding adjustment.

[0056] like Figure 2 As shown, the width of one end of the arc-shaped slot 201 of the baffle 2 is greater than the width of the other end;

[0057] As described above, by setting the width of the arc-shaped groove 201 of the baffle 2 to be larger, it can better support the roller group 100 to avoid slurry overflow, and at the same time, it can also guide the electrode substrate 300.

[0058] like Figure 1 and Figure 3 As shown, the second fixing bolt 4 is used for the detachable connection between the carrier 1 and the coating machine;

[0059] As described above, the carrier 1 is connected to the coating machine via the second fixing bolt 4, and the second fixing bolt 4 is threadedly engaged with the carrier 1.

[0060] Specifically, after the carrier 1 is attached to the horizontal plate 200 by the fixing frame 11, the second fixing bolt 4 passes through one side of the fixing frame 11 and abuts against the horizontal plate 200 to achieve fixation.

[0061] Specific implementation steps:

[0062] The roller assembly 100 and the horizontal plate 200 are integrated on the coating machine. The electrode substrate 300 is pulled by the roller assembly 100, and a slurry tank is set above the horizontal plate 200.

[0063] During coating, the slurry is supplied to the horizontal plate 200, then spreads out and flows towards the roller group 100. At this time, the slurry is limited by the baffle 2, which controls the spread width of the slurry, thereby achieving the coating width control of the electrode substrate 300.

[0064] When adjustments are needed, loosen the first fixing bolt 3 and slide the adjustment baffle 2 to adjust the spacing.

[0065] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
