[0035] The existing cutter may have some plastic adhered on the cutter when cutting the just-cooled and formed plastic strip, affecting the sharpness of the cutter, so that the device is provided with the cutting and cleaning mechanism 3, the cutting and cleaning mechanism 3 comprises a mounting block 301 installed on the side plate 2, a rotating shaft 302 is rotatably connected in a rotating hole formed in the mounting block 301, a roller 303 is installed on the rotating shaft 302, a plurality of cutting blades 304 are annularly arranged on the outer surface of the roller 303, a driving motor 305 is installed on the mounting block 301 to drive the rotating shaft 302 to rotate, and a cleaning assembly 306 is arranged on the mounting block 301 to wipe and clean the plastic melt adhered on the surface of the cutting blade 304, when the plastic strip is conveyed to the cutting blade 304, the driving motor 305 is started to drive the rotating shaft 302 to rotate in the mounting block 301, and then the roller 303 on the rotating shaft 302 is driven to rotate, so that the cutting blade 304 is driven to rotate to cut the plastic strip into particles in sections.

[0036] With the cutting blade 304 cutting the plastic strip, the just-cooled plastic strip core is still high in temperature and soft, so during the cutting process, the cutting blade 304 surface will be contaminated with a layer of plastic film, which will affect the sharpness of the cutting blade 304, so the device is also provided with a cleaning assembly 306, the cleaning assembly 306 includes a door-shaped frame 3061 installed on the two mounting blocks 301, and the bottom of the door-shaped frame 3061 is installed with an electric guide rail 3062, and the electric guide rail 3062 is slidably connected with an electric sliding table 3063 in front and back, and the bottom of the electric sliding table 3063 is installed with a connecting rod 3064, and the bottom of the connecting rod 3064 is installed with a cleaning sliding sleeve 3065 matched with the cutting blade 304, and the door-shaped frame 3061 is provided with a wiping assembly 307 for wiping the cutting blade 304 when rotating to cut material, after the cutting blade 304 completes a round of cutting and resets, the electric sliding table 3063 is driven to move forward along the electric guide rail 3062, thereby driving the cleaning sliding sleeve 3065 on the connecting rod 3064 at the bottom of the electric sliding table 3063 to slide forward and be sleeved on the roller 303 and the cutting blade 304, with the cleaning sliding sleeve 3065 moving forward, the plastic film contaminated on the cutting blade 304 is wiped off, thereby realizing cleaning of the cutting blade 304 and maintaining its sharpness.
