[0028] Working principle:

[0029] Preparation of high-brightness PVC reflective film:

[0030] When applying adhesive to the high-brightness PVC reflective film, hold the rotating shaft 7 and unscrew the bolt 8. Then insert the plastic roll into the left rotating shaft 7, and the aluminum foil roll into the right rotating shaft 7. Next, turn the bolt inwards onto the rotating shaft 7 to limit the plastic roll and aluminum foil roll. Then, add an appropriate amount of adhesive from the top of the first housing 4. Take out one end of the plastic film and feed it in through the left opening and out through the right opening of the first housing 4. Further open the door in the middle of the second housing 5. Then, lift the left frame 204 upwards and slide it upwards inside the second housing 5. During this process, the spring 205 will be compressed. Then, apply the plastic film and... Aluminum foil is fed into the second housing 5. The frame 204 is released and spring 205 pushes the first roller 206 and the second roller 11 to press the plastic film and aluminum foil between them to achieve the extrusion processing of high-brightness PVC reflective film. The plastic film and aluminum foil are then output from the right end opening of the second housing 5 through the same operation. Then the door in the middle of the second housing 5 is closed. The plastic film and aluminum foil are then wrapped and fixed with the external winding roller. The external motor is used to pull the winding roller to pull and wind the plastic film and aluminum foil. The lower left side of the first housing 4 is provided with a discharge port 9. The glue can be discharged by opening the valve in the middle.

[0031] Applying adhesive to high-brightness PVC reflective film:

[0032] When the plastic film and aluminum foil are being wound up, the external power supply of the first motor 101 is turned on. The first motor 101 starts and drives the brush roller 102 to rotate inside the first housing 4 through the sealed bearing. The brush roller 102 brushes an appropriate amount of adhesive from inside the first housing 4 onto the plastic film for gluing. At the same time, the external power supply of the heating plate 105 is turned on. The heating plate 105 starts and powers the internal heating wire, transferring heat to the heating plate to make it heat up. The heat emitted by the heating plate 105 heats the first housing 4 and the adhesive inside. At the same time, the external power supply of the second motor 103 is turned on. The second motor 103 starts and drives the stirring rod 104 to rotate inside the first housing 4 through the sealed bearing. The stirring rod 104 rotates and stirs the adhesive inside. By heating and stirring the adhesive, the solidification speed of the adhesive is effectively slowed down, thereby keeping the adhesive in an optimal viscosity state.

[0033] High-brightness PVC reflective film extrusion and drying process:

[0034] After the plastic film is glued, the first roller 206 and the second roller 11 on the left end perform the initial extrusion and shaping of the plastic film and aluminum foil. At the same time, the external power supply of the hot air blower 201 is turned on. The hot air blower 201 starts and draws air through the right end of the pipe 202. The hot air blower 201 heats the air inside the second box 5 and sprays the hot air onto the plastic film and aluminum foil through the nozzle 203 to dry the glue between them. The dried and shaped high-brightness PVC reflective film is then extruded and shaped again by the first roller 206 and the second roller 11 on the right end. At the same time, the frame 204 and the first roller 206 can block the openings on both sides of the second box 5, which can effectively reduce the leakage of hot air. When the plastic film and aluminum foil are pulled and wound up, the rotating shaft 7, the first roller 206, the second roller 11, and the third roller 10 that are in contact with them will rotate synchronously. The two third rollers 10 play a supporting role.
