[0035] Reference Figure 4 The inner walls of both sides of the two connecting frames 16 are rotatably connected with rotating wheels 14, and the two rotating wheels 14 are respectively fixedly connected to the four screw rods 13. The setting of the rotating wheels 14 facilitates the screw rods 13 to be directly driven to rotate.

[0040] The implementation principle of the present application is as follows: during use, when the lithium-ion battery is coated, the cylinder 6 is controlled by the solenoid valve 7, thereby facilitating the lifting and lowering of the ridge roller 9 on the adjustment frame 8. When the ridge roller 9 descends, it contacts the coating member, and when the ridge roller 9 rises, it is away from the coating member, thereby realizing intermittent coating of the lithium-ion battery. By adjusting the spacing between the two ridge rollers 9, different types of coating can be conveniently realized. During adjustment, the rotating wheel 14 is rotated to drive the two screws 13 to rotate, and the other two screws 13 rotate synchronously between the synchronous wheel and the synchronous belt 15. When the screw 13 rotates, it is convenient to drive the two ridge rollers 9 to move toward or away from each other. When the support roller 19 rotates, the rubber block 24 between the tooth 1 25 and the tooth 2 26 is used for buffering, thereby reducing the friction between the teeth and reducing the noise generated when the support roller 19 rotates.
