Figure 1-2 As shown, the bar coating tool of this application embodiment includes: a bar 102 and upright plates 101 arranged at both ends of the bar 102.

[0027] In an exemplary embodiment, each end of the bar 102 is provided with a convex shaft 105. As needed, the convex shaft 105 can be fixedly connected to the bar 102 or connected through a bearing 112.

The outer layer of the bearing 112 is connected to the inner wall of the groove, and the inner layer of the bearing 112 is connected to the convex shaft 105.

[0028] In an exemplary embodiment, if necessary, when the convex shaft 105 and the wire bar 102 are connected by the bearing 112, in order to prevent the bearing 112 from disengaging from the groove, a locking nut 113 is also provided at the opening of the bearing 112 and the groove.

[0031] In one exemplary embodiment, the upright plate 101 is provided with a guide groove 104, and the convex shaft 105 is disposed in the guide groove 104, which is at least movable in the vertical direction; that is, the convex shaft 105 can move in the guide groove 104 at least in the vertical direction.

[0032] In one exemplary embodiment, the guide groove 104 is a U-shaped groove as needed.

[0033] In one exemplary embodiment, the bar scraper of this application further includes a telescopic unit 106.

[0034] In one exemplary embodiment, the housing of the telescopic unit 106 is fixed on the upright plate 101, and the telescopic rod of the telescopic unit 106 is connected to the convex shaft 105. That is, the telescopic unit 106 restricts the upward movement of the convex shaft 105, thereby limiting the distance of the wire bar 102 away from the coating substrate.

[0035] In one exemplary embodiment, the bar scraper of this application further includes an elastic member 110.

[0036] In one exemplary embodiment, the upper end of the elastic member 110 is connected to the upright plate 101, and the lower end of the elastic member 110 is connected to the convex shaft 105. It can be understood that the elastic member 110 restricts the wire rod 102 from sliding down to the coating substrate. When the telescopic rod of the telescopic unit 106 moves upward, the convex shaft 105 moves upward synchronously, thereby achieving the purpose of increasing the distance between the wire rod 102 and the coating substrate below.

[0037] In one exemplary embodiment, the telescopic unit 106 and the elastic member 110 together limit the displacement distance of the rod 102 in the vertical direction.

[0038] In one exemplary embodiment, the depth dimension of the guide groove 104 matches the distance dimension of the vertical movement of the bar 102.

[0039] In an exemplary embodiment, each upright plate 101 is provided with a telescopic unit 106 and an elastic component 110 at the position corresponding to the guide groove 104; it can be understood that telescopic units 106 and elastic components 110 are provided at both ends of the wire bar 102, and this design makes the distance between the wire bar 102 and the coating substrate below it more precise.

[0040] In one exemplary embodiment, the elastic member 110 is, for example, a spring.

[0041] In one exemplary embodiment, the bar scraper of this application further includes a fixing block 107.

[0047] In one exemplary embodiment, preferably, the contact surface between the convex shaft 105 and the telescopic rod of the telescopic unit 106 is a non-convex surface.

[0048] In one exemplary embodiment, the contact surface between the convex shaft 105 and the telescopic rod of the telescopic unit 106 is a plane or a concave surface; for example, when the convex shaft 105 and the wire rod 102 are connected by the bearing 112, and the contact surface between the convex shaft 105 and the telescopic rod is a plane, the rotation of the convex shaft 105 is restricted, thereby avoiding friction of the telescopic rod caused by the rotation of the convex shaft 105, which in turn affects the control accuracy of the telescopic unit 106.

[0049] In one exemplary embodiment, the bar 102 includes a plurality of bars arranged in parallel; the specific number of bars 102 can be designed as needed, and the plurality of bars 102 are designed for multiple roll coatings.

That is, different wire bars 102 can be selected to use for coating liquids of different viscosities. It can be understood that multiple wire bars 102 can be of the same model or different models.
