[0024] Example 1: Reference Figure 1-4 The raw material gluing device for producing acrylic foam tape shown in the figure comprises a frame 1 and a gluing roller 2 installed on the frame 1, a conveying wheel 3 is installed on the frame 1, a guide wheel 4 is arranged between the conveying wheel 3 and the gluing roller 2, a winding wheel 5 is arranged on the frame 1, the cotton tape is wound on the conveying wheel 3, one end of the cotton tape passes through the guide wheel 4 and the gluing roller 2 and is wound on the winding wheel 5, a tensioning wheel 6 is arranged between the gluing roller 2 and the winding wheel 5, a bracket is slidably connected to the frame 1, the tensioning wheel 6 is rotatably connected to the bracket, and a spring is arranged at the bottom end of the bracket, which cooperates with the guide wheel 4 and the tensioning wheel 6 to provide guidance for the conveying of the cotton tape, and form an inclined downward conveying structure for easy coating For the gluing operation of the glue roller 2, a glue width adjusting unit 7 for adjusting the glue outlet width of the glue roller 2 is provided on the frame 1. The glue width adjusting unit 7 includes a plurality of glue outlet holes 10 provided on the glue roller 2. An isolation sleeve 12 is sleeved on the glue roller 2. A connecting shaft 14 is fixedly connected to the isolation sleeve 12. A glue inlet pipe is fixedly connected to one end of the glue roller 2. One end of the connecting shaft 14 is inserted into the glue inlet pipe. A limiting protrusion 17 is fixedly connected to the end of the connecting shaft 14.

A flow valve 9 is installed on the glue inlet pipe. The flow valve 9 is a prior art. The flow rate of glue is controlled by the flow valve 9.

[0025] When in use, before the cotton tape is conveyed, the isolation sleeve 12 is pushed to move on the glue coating roller 2, so that the isolation sleeve 12 blocks the glue outlet hole 10 on the glue coating roller 2, so as to achieve the purpose of adjusting the glue coating width. Then the glue coating roller 2 is tightly attached to the cotton tape, and the glue is discharged through the glue outlet hole 10 on the glue coating roller 2 to achieve the gluing work.
