[0012] Compared with the prior art, the advantages and positive effects of the utility model are:

[0013] 1. The utility model connects the device to an external power source through a line and starts it through an external controller. The device is pre-connected to a plastic extruder. When the staff needs to manufacture plastic masterbatch, two motors 1 and one motor 2 are pre-started, and multiple plastic rods passing through the cooling pool are placed in multiple semicircular grooves respectively, and are pushed forward to the bottom of multiple annular grooves using a tool. The surfaces of the multiple annular grooves are all fitted with multiple plastic rods, and the motor 1 connected thereto drives itself to rotate, and the multiple plastic rods are pushed into the box to the top of another roller. At this time, the roller is driven to rotate by the motor 2, and the roller at the bottom of the roller is driven by another motor 1. By rotating in opposite directions, multiple plastic rods can be cut into granules. After cutting, the plastic masterbatch falls along the baffle to the top of the first-level screen, and the vibration motors on both sides of the bottom of the first-level screen and the second-level screen are started. The vibration of the vibration motor drives the first-level screen and the second-level screen to vibrate synchronously. At the same time, the corresponding telescopic rods and springs connected around the bottom limit and buffer themselves, so that the qualified plastic masterbatch on the top of the first-level screen falls to the top of the second-level screen, and then the cut powder on the top of the second-level screen falls into the inside of the collection box, thereby completing the graded screening. After the pelletizing is completed, the bottom rotary lock is unlocked from the inside of the lock block, and the door panel is opened. Then the working The personnel pull out the first-level screen, and the first-level screen is moved by force, driving the four telescopic rods and the supporting blocks connected to it to move. The movement of the four supporting blocks drives the connecting rod 1 connected to it to move. The movement of the connecting rod 1 drives the two connecting blocks connected to it to move.

After the connecting rod 2 moves to the vertex of one end of the hollow limit block, the grooves 3 and 2 on both sides are separated from the limit blocks on both sides. The diameter of the connecting rod 2 is much smaller than the width of the inner cavity of the hollow limit block, so that the connecting rod 2 can be in the hollow limit block. The interior moves up and down and left and right. When the two support blocks on the inner side are disengaged from the limit block and move to the top side of the hollow limit block, the connecting rod one drives the connecting rod two to move upward and tilt inside the hollow limit block, so that the support block can be disengaged from the top of the hollow limit block.

[0014] 2. According to the utility model, when it is necessary to manufacture plastic masterbatches of different specifications, the rotary lock is rotated to open the door panel 2, and then the fixing sleeve is rotated by the handles on both sides of the fixing sleeve to unlock the external thread groove from the inside of the internal thread, and then the fixing sleeve is pulled out. After the fixing sleeve is pulled out, the four limit strips 2 are pulled out from the inside of the hob and the four grooves 1, and the hob is rotated after being pulled out so that the four limit strips 1 inside it are rotated from the four through grooves 2 to the inside of the groove 1, and then the hob is pulled out. After the hob is pulled out, the hob of other specifications can be replaced. After the replacement is completed, the hob of the new specification is re-set into the surface of the outer sleeve through the four grooves, and then rotated and buckled into the inside of the through groove 2. After rotation, the above operation can be reversed to re-embed the limit strip 2 and the fixing sleeve to complete the fixation. In this way, when the staff needs to manufacture plastic masterbatches of different specifications and thus needs to replace the hob with a larger knife groove spacing, the hob can be conveniently disassembled and assembled, and the use efficiency of the pelletizer will not be affected.

[0042] Working principle: the device is connected to an external power supply through a line and started by an external controller. The device is connected to a plastic extruder in advance. When the staff needs to make plastic masterbatch, two motors 1 3 and one motor 2 401 are started in advance. The multiple plastic rods passing through the cooling pool are placed in multiple semicircular grooves 201 respectively, and are pushed forward to the bottom of the multiple annular grooves 303 using a tool. The surfaces of the multiple annular grooves 303 are all fitted with the multiple plastic rods, and the motor 1 3 connected thereto drives itself to rotate, and the multiple plastic rods are pushed into the box 1 to the top of another roller 302. At this time, the motor 2 401 drives the roller 407 to rotate, and the other motor 1 3 drives the roller 302 on the bottom side of the roller 407 to rotate in the opposite direction. Then, multiple plastic rods can be cut into granules. After cutting, the plastic masterbatch falls along the baffle 203 to the top of the primary screen 6, and the vibration motors 601 on both sides of the bottom of the primary screen 6 and the secondary screen 7 are started. The vibration of the vibration motor 601 drives the primary screen 6 and the secondary screen 7 to vibrate synchronously. At the same time, the telescopic rods 504 and springs 505 correspondingly connected around the bottom thereof are used to limit and buffer themselves, so that the qualified plastic masterbatch on the top of the primary screen 6 falls to the top of the secondary screen 7, and then the cut powder on the top of the secondary screen 7 falls into the inside of the collecting box 8, thereby completing the graded screening. After the granulation is completed, the bottom rotary lock buckle 104 is unlocked from the inside of the lock block 103, and the door panel 101 is opened. Then, the staff pulls out the primary screen 6. The first-level screen 6 is forced to move and drive the four telescopic rods 504 and the support block 501 connected thereto to move. The four support blocks 501 move and drive the connecting rod 1 506 connected thereto to move. The connecting rod 1 506 moves and drives the two connecting blocks 507 connected thereto to move. The connecting block 507 moves and drives the connecting rod 2 508 connected thereto to move. The connecting rod 2 508 is limited by the hollow limit blocks 509 on both sides. The limit blocks 106 on both sides limit the grooves 3 503 and the grooves 2 502 on both sides. After the connecting rod 2 508 moves to the vertex of one end of the hollow limit block 509, the grooves 3 503 and the grooves 2 502 on both sides are separated from the limit blocks 106 on both sides. The diameter of the connecting rod 2 508 is much smaller than the width of the inner cavity of the hollow limit block 509. The degree of rotation of the connecting rod 508 allows the second connecting rod 508 to move up and down and left and right inside the hollow limit block 509. When the two support blocks 501 located on the inside are disengaged from the limit block 106 and move to the top side of the hollow limit block 509, the first connecting rod 506 drives the second connecting rod 508 to move upward and tilt inside the hollow limit block 509, so that the support block 501 can be separated from the top of the hollow limit block 509. At this time, one end of the first-level screen 6 can be tilted downward to facilitate the staff to unload, and the same method can be used to tilt the second-level screen 7. In this way, when using a pelletizer to process plastic rods, plastic master batches exceeding a predetermined size and the cut powder mixed in the master batches after pelletizing can be graded and screened.The quality of the master batch is not affected. When it is necessary to manufacture plastic master batches of different specifications, the rotary lock buckle 104 is rotated to open the door panel 102, and then the fixed sleeve 413 is rotated by the handles on both sides of the fixed sleeve 413 to unlock the external thread groove 414 from the inside of the internal thread 409, and then the fixed sleeve 413 is pulled out. After the fixed sleeve 413 is pulled out, the four limiting strips 410 are pulled out from the inside of the hob 407 and the four grooves 405. After the hob 407 is pulled out, the four limiting strips 408 inside it are rotated from the four through grooves 406 to the inside of the grooves 405. , and then pull out the roller cutter 407. After the roller cutter 407 is pulled out, it can be replaced with a roller cutter 407 of other specifications. After the replacement is completed, the roller cutter 407 of the new specification is re-set into the surface of the outer sleeve 404 through the four grooves 1 405, and then rotated to snap into the inside of the through groove 2 406. After rotation, the above operation can be reversed to re-embed the limit strip 2 410 and the fixed sleeve 413 to complete the fixation. In this way, when the staff needs to manufacture plastic masterbatches of different specifications and needs to replace the roller cutter with a larger groove spacing, the roller cutter can be easily disassembled and assembled without affecting the efficiency of the pelletizer. ,
