[0028] A plastic masterbatch processing device comprises a partition 01, and a plurality of rotating tubes 02 rotatably connected to the partition 01, the front end of each rotating tube 02 is welded with a toothed ring 03 and every two adjacent toothed rings 03 are meshed with each other, the inner wall of each rotating tube 02 is bonded with a rubber ring 04, the inner wall of the rubber ring 04 is formed with a plurality of ridges, and a gear 05 meshing with one of the toothed rings 03 is rotatably connected to the partition 01; the state of the long strip extruded by the extruder can be deformed under the action of external force when it is not completely cooled and formed, and the long strip passes through the rubber ring 04, so that the long strip squeezes the rubber ring 04 and passes through Friction is increased through contact, and then the power source can be used to drive the gear 05 to rotate, so that the gear ring 03 drives the rotating tube 02 to rotate, and the rotating tube 02 drives the rubber ring 04 to drive the long strip to rotate, thereby achieving the twisting effect of the long strip, which can form spiral patterns on the surface of the long strip, and use the spiral patterns to increase the contact area with the air to accelerate cooling and forming. At the same time, the surface of the long strip can also be cracked due to the force of twisting, thereby making the surface of the long strip rougher. When the contact area with the air is increased, the surface roughness can also be increased. After the long strip is processed into particles, the melting efficiency can be improved when heated.

[0029] See attached Figures 1 to 10 From the structure shown, it can be understood that an exemplary operation process of fixing the strip of the present application is:

[0030] The rear end of the partition 01 is fixedly connected to the bottom box 06, and the rear end of the bottom box 06 is welded to the rear plate 07, and a plurality of round holes are opened on the rear plate 07.

[0031] A rubber block 11 is fixedly connected to the inner side of the clamping plate 10 , and the elastic deformation of the rubber block 11 can be used to protect the long strip, thereby preventing the long strip from being deformed due to direct clamping.

[0036] In addition, the rubber sleeve 17 can be used to increase the buffering of the contact between the roller 16 and the long strip to avoid deformation of the long strip caused by excessive clamping force. At the same time, the rubber sleeve 17 can be used to increase the friction between the roller 16 and the long strip, making it easier to pull the long strip.

[0037] Refer to the attached Figures 1 to 10 From the structure shown, it can be understood that an exemplary operation process of the cleaning strip of the present application is:
