Then, by using the cooperation between the disc and the pressure wheel, the cardboard box can be glued. By using the thread action between the lead screw and the threaded sleeve, the slider can be driven to move up and down in the slide groove, which can drive the disc to move up and down in the glue hopper, ensuring that the disc is always in contact with the glue.

[0021] 2. By setting up a stirring mechanism, not only can the glue be initially stirred and mixed to avoid solidification in the mixing bin, but the inner wall of the mixing bin can also be cleaned, improving the practicality of the device. The second drive motor drives the drive wheel to rotate, and the meshing action between the drive wheel and the first and second driven wheels can drive the stirring frame to rotate forward or backward, thus stirring and mixing the glue.

[0031] An elastic sheet 108 is fixedly connected to the outer side of one end of the roller 107. The end of the roller 107 near the elastic sheet 108 passes through the glue box hopper 102 and is fixedly connected to the first drive motor 109.

A fixing frame 204 is fixedly connected to the top of the sealing cover 203. Rotating the sealing cover 203 facilitates cleaning of the inner wall of the mixing bin 201.

[0034] One side of the fixed frame 204 is fixedly connected to the second drive motor 205. The output end of the second drive motor 205 passes through the fixed frame 204 and is fixedly connected to the drive wheel 206. One side of the drive wheel 206 is meshed with the first driven wheel 207. The center of the first driven wheel 207 is fixedly connected to the rotating shaft 208.

[0035] The other side of the driving wheel 206 is engaged with a second driven wheel 209. The center of the second driven wheel 209 is fixedly connected to the rotating shaft 208. The outer side of the bottom end of the rotating shaft 208 is fixedly connected with a bearing 210. The outer side of the bearing 210 is fixedly connected to the sealing cover 203. The bottom end of the rotating shaft 208 is fixedly connected with a stirring frame 211. The left and right sides of the stirring frame 211 are symmetrically threaded with cleaning brushes 212. One side of the cleaning brush 212 is in close contact with the mixing chamber 201. One side of the bottom of the mixing chamber 201 is fixedly connected with a water pump 213. One end of the water pump 213 is fixedly connected to the glue hopper 102. When stirring the glue, the cleaning brush 212 needs to be removed from the stirring frame 211.

[0036] Working principle: Before using this device for unclogging the glue hopper of a carton gluing machine, it is necessary to check the overall condition of the device to ensure it can work normally. Figure 1 - Figure 5 As shown, firstly, the glue is poured into the mixing hopper 201 and the heating coil 202 is turned on to heat the glue inside the mixing hopper 201. Then, the second drive motor 205 is started to drive the drive wheel 206 to rotate. By utilizing the meshing action between the drive wheel 206 and the first driven wheel 207 and the second driven wheel 209, the stirring frame 211 can be driven to rotate forward or reverse, which can stir and mix the glue. Then, the water pump 213 is started to input the glue in the mixing hopper 201 into the glue box hopper 102.

[0037] Secondly, starting the first drive motor 109 drives the roller 107 to rotate, which enables the elastic sheet 108 and the disc 110 to rotate, stirring the glue inside the glue hopper 102 to prevent solidification. At the same time, the contact between the disc 110 and the glue allows the glue to adhere to its surface. Then, the cooperation between the disc 110 and the pressure wheel 111 allows the glue to be applied to the passing paper box.

[0038] When the disc 110 is not in contact with the glue, rotating the lead screw 105, using the thread action between the lead screw 105 and the threaded sleeve 104, drives the slider 106 to move up and down in the slide groove 103, which in turn drives the disc 110 to move downward in the glue hopper 102, ensuring that the disc 110 is always in contact with the glue. At the same time, rotating the nut drives the connecting plate 113 and the pressure roller 111 to move downward simultaneously, so that the cooperation between the disc 110 and the pressure roller 111 can be used to apply glue to the passing cardboard box.

[0039] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
