The discharge platform 104 is set below the front end of the guide platform 101. The discharge platform 104 is inclined, so that the pellets of the masterbatch strips 103 can be smoothly discharged after being cut. It is avoided as much as possible that the unloading platform 104 is not provided, resulting in the viscosity-enhanced masterbatch after the pelletization falling to various places and affecting the material collection. A motor 2 is installed on the inner wall of one side of the masterbatch operation frame 1, and a sprocket A201 is installed on the outer wall of the output shaft of the motor 2, so that the motor 2 can control the drive sprocket A201 to rotate forward or reverse;

[0024] Bearing seats 3 are installed on both sides of the top of the guide platform 101. A rotating shaft 301 is installed inside the bearing seats 3. The rotating shaft 301 is installed at the front of the top of the guide platform 101 by the bearing seats 3. The bearings are fixed between the bearing seats 3 and the rotating shaft 301, so that the bearing seats 3 are fixed to the rotating shaft 301 without affecting the rotation of the rotating shaft 301. A sprocket B302 is installed at one end of the rotating shaft 301. The sprocket B302 is connected to the sprocket A201 through a chain meshing connection, so that the motor 2 can drive and control the rotating shaft 301 to rotate forward or reverse. Both sides of the outer wall of the rotating shaft 301 are installed with bumps 303, and one end of the bump 303 is rotatably connected to a roller 304.

[0025] Guide rods 4 are installed on both sides of the top of the masterbatch operation frame 1. A limit nut 401 is arranged above the outer wall of the guide rod 4. The inner wall of the limit nut 401 is threadedly connected to the upper outer wall of the guide rod 4. A spring 402 is arranged below the outer wall of the guide rod 4. A knife seat 5 is installed in front of the end face of the guide platform 101. Guide seats 501 are installed on the outer walls of both sides of the knife seat 5. A guide hole B502 is opened at the center of the surface of the guide seat 501. The inner wall of the guide hole B502 is slidably connected to the outer wall of the guide rod 4. The knife seat 5 is arranged on the outer wall of the guide rod 4 in a sliding manner by the guide seat 501 and the guide hole B502. The limiting nut 401 is installed on the outer wall of the guide rod 4 in a threaded connection manner, so that the knife seat 5 can move vertically up and down on the outer wall of the guide rod 4. At the same time, the limiting nut 401 can limit the knife seat 5 to prevent the knife seat 5 from being separated from the guide rod 4. According to the spring 402 under the outer wall of the guide rod 4, the spring 402 has an elastic reaction force, so that the spring 402 in an unpressurized state can reset the knife seat 5. By correspondingly arranging protrusions 303 on both sides of the outer wall of the rotating shaft 301, and arranging the roller 304 on the protrusion 303 in a rotatable connection manner. At one end, the rotating shaft 301 rotates forward or reversely, which can drive the protrusion 303 to press the knife seat 5.

At the same time, the rolling effect of the roller 304 reduces the friction phenomenon caused by the protrusion 303 on the surface of the knife seat 5. A pelletizing knife 503 is installed at the bottom rear end of the knife seat 5. The length of the pelletizing knife 503 needs to cover the masterbatch strip 103 on the guide platform 101, so that the knife seat 5 in the continuously jumping state can pelletize the masterbatch strip 103 with the pelletizing knife 503, and the pelletizing knife 503 in the synchronous moving state can ensure the synchronization of pelletizing the masterbatch strip 103. At the same time, the pelletizer is pressed by the protrusion 303 to exert a certain pressure, which is sufficient to pelletize the masterbatch strips 103, and try to avoid poor synchronization or insufficient force in the pelletizing process, which may cause the pelletizing to be different in size and affect the quality of the thickened masterbatch after pelletizing. At the same time, according to the spring 402 and the pelletizer 503 that have been used for a long time, the limit nut 401 can be disassembled, the spring 402 can be removed, and a new spring 402 can be replaced, and try to avoid the situation where the elasticity of the spring 402 is weakened after long-term use and affects the pelletizing effect. The disassembled pelletizer 503 can be polished to maintain its sharpness.

[0026] Working principle: When using the utility model, the guide platform 101 on the masterbatch operating frame 1 is provided with several guide holes A102 as needed, so that the masterbatch strips 103 can be positioned and guided by the guide holes A102, and the occurrence of the masterbatch strips 103 sticking to each other is minimized. By setting a discharge platform 104 below the front end of the guide platform 101, and the unloading platform 104 is inclined, it is convenient for the masterbatch strips 103 to slide and unload smoothly after being cut into pellets in the later stage, and the occurrence of the viscosity-enhanced masterbatch after being cut falling to various places and affecting the material collection due to the lack of the unloading platform 104 is avoided as much as possible. By installing the motor 2 on the inner wall of one side of the masterbatch operating frame 1, and installing the sprocket A201 on the outer wall of the output shaft of the motor 2, the motor 2 The drive sprocket A201 can be controlled to rotate forward or reverse.

The bearing seat 3 and the shaft 301 are fixed by the bearing seat 3, so that the bearing seat 3 is fixed to the shaft 301 without affecting the rotation of the shaft 301. The sprocket B302 on the shaft 301 is meshed with the sprocket A201 by a chain, so that the motor 2 can drive the shaft 301 to rotate forward or reverse. The knife seat 5 is set on the outer wall of the guide rod 4 in a sliding manner by the guide seat 501 and the guide hole B502, and the limit nut 401 is installed on the outer wall of the guide rod 4 in a threaded manner, so that the knife seat 5 can move vertically up and down on the outer wall of the guide rod 4, and the limit nut 401 can be installed on the outer wall of the guide rod 4 in a threaded manner. The positioning nut 401 can limit the knife seat 5 to prevent the knife seat 5 from separating from the guide rod 4. The spring 402 under the outer wall of the guide rod 4 can be used to make the spring 402 in an unpressurized state have an elastic reaction force, so that the knife seat 5 can be reset. By correspondingly arranging protrusions 303 on both sides of the outer wall of the rotating shaft 301, and arranging the roller 304 at one end of the protrusion 303 in a rotating connection manner, the rotating shaft 301 can be rotated forward or reversely, which can drive the protrusion 303 to press the knife seat 5. During this period, the spring 402 will elastically reset the knife seat 5 to form an effect of continuous up and down jumping. At the same time, the rolling effect of the roller 304 reduces the friction phenomenon caused by the protrusion 303 on the surface of the knife seat 5. A fixed pelletizer 503 is installed at the rear, and the length of the pelletizer 503 needs to cover the masterbatch strip 103 on the guide platform 101, so that the knife seat 5 in the continuously jumping state can pelletize the masterbatch strip 103 with the pelletizer 503, and the pelletizer 503 in the synchronous moving state can ensure the synchronization of pelletizing the masterbatch strip 103. At the same time, the pelletizer is pressed by the protrusion 303 to exert a certain pressure, which is sufficient to pelletize the masterbatch strip 103, and try to avoid the situation where the pelletizing process is poorly synchronized or insufficient in strength, and the pelletizing process is uneven in size, which affects the quality of the thickened masterbatch after pelletizing. At the same time, according to the spring 402 and the pelletizer 503 in the long-term use state, the limit nut 401 can be disassembled, the spring 402 is removed, and a new spring 402 is replaced.Try to avoid the situation where the spring 402's elasticity weakens after long-term use and affects the pelletizing effect. The pelletizing knife 503 can be polished after disassembly to maintain its sharpness, which effectively improves the use effect of the pelletizing device dedicated to the viscosity-enhancing masterbatch, and also directly and effectively improves the pelletizing efficiency and quality of the viscosity-enhancing masterbatch.
