In addition, the technical features involved in each embodiment of the present application described below can be combined with each other as long as they do not conflict with each other.

[0016] The application discloses a coating machine with replaceable roller, which comprises a mounting frame 1, a roller group 4 magazine 2, a magazine rail 3, a roller group 4, a speed reducer 5, and the mounting frame 1 is provided with a magazine opening 11 at opposite positions on both sides, the roller group 4 magazine 2 is composed of a magazine body 21 and a support plate 22, the magazine body 21 is a box-shaped structure with an upper opening, which is beneficial to isolate different roller group 4 magazines 2 when multiple roller group 4 magazines 2 are arranged, so as to avoid the influence of glue dripping during glue coating. The two ends of the magazine body 21 extend outward and are provided with the support plate 22, the roller group 4 is installed on the upper part of the magazine body 21 through the support plate 22, and the roller group 4 can rotate freely on the upper part of the magazine body 21. The shape of the support plate 22 matches the magazine opening 11, so that the support plate 22 can be directly embedded in the magazine opening 11 during installation, the roller group 4 can be quickly aligned during replacement through the magazine opening 11, and the magazine opening 11 can also support the support plate 22. The roller group 4 magazine 2 is provided with a limiting block 221 on the support plate 22 near the first magazine opening 11 after entering another magazine opening 11 through one magazine opening 11, and the limiting block 221 is fixedly connected with the mounting frame 1 through bolts, so as to avoid the movement of the roller group 4 magazine 2. The number or installation position of the limiting block 221 is not limited, as long as the surface of the limiting block 221 can abut against the installation surface after the roller group 4 magazine 2 is aligned, and the roller group 4 magazine 2 does not displace after being fixed. The end of the rotating shaft of the roller group 4 protrudes from the mounting frame 1 and is provided with a rotating gear 41, the rotating shaft of the rotating gear 41 is connected with the speed reducer 5, and the speed reducer 5 is fixedly connected with the mounting frame 1 through a support frame. The rotating shaft of the rotating gear 41 and the speed reducer 5 can be quickly connected, and the speed reducer 5 can drive the rotating shaft to rotate, for example, a shaft sleeve is fixed on the rotating shaft of the speed reducer 5, the upper and lower surfaces of the rotating shaft of the rotating gear 41 are both planar, and a cavity matched with the shaft sleeve is arranged in the shaft sleeve, so that the rotating shaft of the rotating gear 41 and the speed reducer 5 can be quickly connected. Of course, this is only an example, and the connection mode is not limited to this mode, and any connection mode that can quickly connect and ensure that the speed reducer 5 can drive the rotating gear 41 to rotate can be used.

[0017] In order to facilitate the installation of the roller magazine, the inside of the mounting frame 1 is provided with a magazine rail 3, the top of which is flush with the bottom surface of the magazine opening 11, and the bottom of the magazine body 21 is provided with a groove 211 matched with the magazine rail 3. Through the cooperation of the magazine rail 3 and the groove 211, the roller magazine can be quickly disassembled and installed.

[0018] Further improvement, the outside of the mounting frame 1 is provided with an auxiliary frame 6, one end of which is detachably fixedly connected with the mounting frame 1, and the bottom near the other end of the auxiliary frame 6 is provided with a lifting mechanism 7. The inside of the auxiliary frame 6 is provided with a guide rail connected with the magazine rail 3. When the mounting frame 1 is provided with multiple groups of roller magazines, the alignment and installation of the upper, middle and lower roller groups 4 can be realized through the lifting mechanism 7. In addition, in order to realize the alignment of the auxiliary frame 6 and the mounting frame 1, the auxiliary frame 6 can be provided with an embedding position on the side of the mounting frame 1.
