In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention can also be implemented in other ways different from those described herein, and those skilled in the art can make similar generalizations without violating the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

[0022] like Figure 1-Figure 3 As shown, the utility model discloses a roll-to-roll steel plate coating machine, please refer to Figure 1 From right to left, there are an unwinding structure 1, a first double-roller structure 2, a coating chamber 3, a second double-roller structure 4 and a winding structure 5.

[0023] The coating chamber 3 is used to coat steel materials, such as Figure 3 As shown, an evaporation boat 31 is rotatably arranged in the coating chamber 3, and the evaporation boat 31 is arranged at the bottom of the coating chamber 3, and the evaporation boat 31 contains the material to be plated. Figure 2 and Figure 3 Two opposite side walls of the coating chamber 3 are respectively provided with a horizontal steel material inlet groove 32 and a horizontal steel material outlet groove 33.

[0024] A first double roller structure 2 is provided at the steel material inlet groove 32, and the first double roller structure 2 includes a lower roller 21, an upper roller 22, a guide rod 23 and a screw rod 24. The lower roller 21 is arranged horizontally, and the lower roller 21 is rotatably connected to the side wall of the coating chamber 3. The height of the lower roller 21 is not adjustable. It should be noted that the upper edge of the lower roller 21 is lower than the lower edge of the steel material inlet groove 32. The upper roller 22 is arranged horizontally above the lower roller 21, and the first fixed block 221 and the second fixed block 222 are rotatably connected at both ends of the upper roller 22, and the first fixed block 221 and the second fixed block 222 are respectively abutted against the two side walls of the coating chamber 3. The top of the first fixed block 221 is rotatably connected to the guide rod 23, and the guide rod 23 extends vertically, and the guide rod 23 passes through the top of the coating chamber 3 and extends to the top of the coating chamber 3, and the guide rod 23 is not threadedly connected to the coating chamber 3. The top of the second fixed block 222 is rotatably connected to a screw rod 24 , which is threadedly connected to the top of the coating chamber 3 . The screw rod 24 extends above the coating chamber 3 . The length of the screw rod 24 is not greater than the length of the guide rod 23 . The top of the screw rod 24 is fixedly connected to a hand wheel 25 .

[0025] The unwinding structure 1 comprises a support 13, a motor 11 and an unwinding roller 12. The motor 11 is transmission-connected to the unwinding roller 12, the unwinding roller 12 is rotationally connected to the support 13, and the unwinding roller 12 is arranged transversely.

[0026] The structure of the second double roller structure 4 is the same as that of the first double roller structure 2 , and the second double roller structure 4 is arranged at the steel material outlet groove 33 .

[0027] The structure of the winding structure 5 is the same as that of the unwinding structure 1 .

During coating, the motor 11 is started, and the motor 11 drives the unwinding roller 12 to rotate and continue to unwind the steel 6. At the same time, the winding structure 5 is started and the steel 6 is wound. With the cooperation of the unwinding structure 1 and the winding structure 5, the steel 6 can move from right to left. During the movement of the steel 6, the steel 6 is clamped between the lower roller 21 and the upper roller 22. The hand wheel 25 is turned, and the hand wheel 25 drives the screw rod 24 to rotate, thereby adjusting the height of the screw rod 24.
