[0020] In order to more clearly set forth the structural features and effects of the utility model, the utility model will be described in detail below in combination with the drawings and specific embodiments.

[0021] As Figures 1-4As shown, the glue feeding device in the embodiment of the utility model, including roller assembly 1, the roller assembly 1 includes main roller 101, glue guide hole 102 and roller groove 103, the wall surface of main roller 101 is circumferentially arranged with several glue guide holes 102, the outer wall side of main roller 101 is also provided with roller groove 103;Glue supply assembly 2, the glue supply assembly 2 includes glue supply pipe 201, outer ring groove 202 and overflow glue hole 203, the glue supply pipe 201 is arranged in the inside of main roller 101 and is coaxially arranged with main roller 101, the wall surface of glue supply pipe 201 is circumferentially arranged with several outer ring grooves 202, the outer wall of glue supply pipe 201 is also provided with overflow glue hole 203;Adjusting assembly 3, the adjusting assembly 3 includes sleeve ring 301, drainage hole 302 and shell 303, the sleeve ring 301 is rotatably assembled in overflow glue hole 203, the wall surface of sleeve ring 301 is circumferentially arranged with several drainage holes 302, the shell 303 one end is communicated with drainage hole 302, and the other end of shell 303 is fixedly assembled on main roller 101 and is matched with the glue guide hole 102 on the wall surface of main roller 101.

[0022] When the glue feeding device is used for coating operation in the actual application of the embodiment, the main roller 101 is used for rolling the surface of the substrate and coating glue, the end of the glue supply pipe 201 is communicated with the pipeline for supplying glue, and the glue supply pipe 201 and the main roller 101 relatively rotate, the glue flows into the overflow glue hole 203 through the several outer ring grooves 202 on the surface of the glue supply pipe 201, since one end of the sleeve ring 301 is rotatably assembled in the overflow glue hole 203, the glue can be drained into the shell 303 through the drainage hole 302, and when the glue is in the shell 303, since the end of the shell 303 is fixedly arranged on the cavity wall of the main roller 101, the tapered plug 308 in the shell 303 can slide against the elastic force when subjected to the centrifugal force during rotation, and the linear sliding distance of the tapered plug 308 is positively correlated with the rotation speed of the main roller 101, when the rotation speed of the main roller 101 is faster, that is, the rolling speed of the main roller 101 on the surface of the substrate is faster, the volume of the glue flowing out from the shell 303 per unit time is more, so that the output of the glue can be adaptively adjusted according to the rotation speed of the main roller 101.

[0023] In one case of the embodiment, the rotating sealing structure is adopted between the outer ring groove 202 and the sleeve ring 301.

[0024] As Figure 4 As shown in a preferred embodiment of the utility model, the adjusting assembly 3 further includes a positioning plate 304 and a leakage hole 305, the positioning plate 304 is fixedly arranged in the shell 303, and the leakage hole 305 is further arranged on the positioning plate 304.

[0025] In actual application, the positioning plate 304 is arranged on one side of the drainage hole 302, and the leakage hole 305 arranged on the positioning plate 304 ensures that the drainage hole 302 and the shell 303 are always in communication.

[0026] As shown in the preferred embodiment of the utility model, the adjusting assembly 3 further comprises a positioning rod 306, a conical cavity 307, a conical plug 308, an elastic element 309 and a glue discharging port 310. Figure 4 The positioning rod 306 is fixedly assembled on the positioning plate 304, the conical plug 308 is axially slidably assembled on the positioning rod 306, and the conical plug 308 and the positioning plate 304 are elastically connected through the elastic element 309.

[0027] In actual application, the conical plug 308 is slidably arranged on the positioning rod 306, and the conical plug 308 and the positioning plate 304 are elastically connected through the elastic element 309. When the main roller 101 drives the sleeve ring 301 to rotate, the conical plug 308 slides away from the positioning plate 304 under the action of centrifugal force, and in the process of sliding, the conical surface of the conical plug 308 matches the conical surface of the conical cavity 307. When the conical plug 308 moves towards the glue discharging port 310, the distance between the conical surface of the conical plug 308 and the conical surface of the conical cavity 307 continuously increases, so that the glue flow in the conical cavity 307 per unit time increases, and the glue output on the glue discharging port 310 side increases. The sliding distance of the conical plug 308 on the positioning rod 306 is positively correlated with the rotation speed of the main roller 101, so that the extension position of the conical plug 308 can be synchronously adjusted by the rolling speed of the main roller 101.

[0028] In one case of the embodiment, the gap between the conical cavity 307 and the conical plug 308 is matched to ensure that the drainage hole 302 and the shell 303 are always in communication, and when the conical plug 308 is pressed on one side of the positioning plate 304, the glue output on the glue discharging port 310 side is at a minimum value. By controlling the rolling speed of the main roller 101, the glue output on the glue discharging port 310 side can be controlled.

[0029] The gluing device of the coating machine provided in the above embodiment of the utility model, by setting the rotating main roller 101 outside the glue supply pipe 201, and setting the adjusting assembly 3 between the main roller 101 and the glue supply pipe 201, can adjust the glue output of the sleeve ring 301 according to the roller pressure speed of one side of the main roller 101, so that the output of the glue can be adaptively adjusted according to the rotation speed of the main roller 101.
