[0042] When the masterbatch needs to be fed into the granulator 1 for hot melting, the masterbatch is first conveyed to the top of the discharge bin 3 by the feeder 5. When the masterbatch needs to be screened according to its size, the conveying speed of the feeder 5 is first adjusted to ensure that the masterbatch enters the discharge bin 3 evenly. Then, according to the type and particle size of the masterbatch, the hydraulic push rod 324 on the control panel 321 is operated to make the push block 325 and the push plate 326 work together, and the cylindrical slider 328 is pushed and slid through the two inclined slide grooves 327, so that the discharge port adjustment plate 3211 performs corresponding opening and closing actions, thereby controlling the size of the discharge port. The opening and closing degree of the discharge port adjustment plate 3211 determines the discharge rate and amount of the masterbatch.

[0043] In addition, in order to ensure the smoothness of the material discharge process, when the push plate 326 moves, the two lifting rods 3212 will rise and fall synchronously, and the lifting block 3213 will move up and down in the slide groove 314 accordingly, ensuring that the plate 3214 pushes the wheel hub 3215 on the beveled surface of the plate 3214 through the beveled surface, thereby pushing the cylindrical push rod 3218 to push and pull, and then pushing the sliding plate 315 to rotate, and the flow rate of the masterbatch is controlled by the rotation angle of the sliding plate 315. Through this design, the material discharge rate and amount of the masterbatch can be accurately controlled to adapt to masterbatch of different types and particle sizes, ensuring the efficiency and stability of the granulation process;

[0044] During the feeding process, if the masterbatch particles are too large and need to be crushed, the crushing mechanism 4 will start to crush the large particles of the masterbatch to ensure that it can pass through the feeding port smoothly. The crushing effect of the crushing mechanism 4 directly affects the quality and efficiency of granulation, so its working status needs to be monitored and adjusted in real time.

[0045] See also Figure 8-10The crushing mechanism 4 includes a crushing mechanism control frame 41, the front side of the crushing mechanism control frame 41 is fixedly connected to the middle of the bottom of the rear side of the push-pull groove 318, and the inner walls on the left and right sides of the crushing mechanism control frame 41 are rotatably connected with crushing plates 42. The crushing mechanism control frame 41 includes a motor 411, and the left and right sides of the motor 411 are respectively fixedly connected with C-shaped frames 412. The top and bottom of the outer sides of the two C-shaped frames 412 are fixedly connected with inverted L-shaped connecting rods 4110. The two sets of inverted L-shaped connecting rods 4110 are The outer sides are fixedly connected with a particle board slide plate 4111, the top and bottom of the two C-shaped frames 412 are fixedly connected with two C-shaped frame connecting rods 413, the front sides of the four groups of C-shaped frame connecting rods 413 are fixedly connected to the middle of the bottom of the rear side of the push-pull groove 318, the output end of the motor 411 is fixedly connected with a turntable 414, and the outer walls of the turntable 414 are respectively covered with crawlers 415 on both sides, and the second turntable 416 is covered on the side away from the turntable 414. The top of the inner wall of the two C-shaped frames 412 is fixedly connected to the middle of the bottom of the rear side of the push-pull groove 318. The top and bottom of the two sets of rotating rods 418 are rotatably connected to the push-pull rod connecting shaft 419, the tops of the two top rotating rods 418 are respectively fixedly connected to the bottom ends of the rotating rods 417, and the two particle boards 42 include push-pull plates 421, and the tops and bottoms of the two push-pull plates 421 are fixedly connected to push-pull plate slide rods 423, and the outer walls of the two push-pull plate slide rods 423 are respectively slidably connected to the inner sides of the left and right sets of particle board slide groove plates 4111, and the two push-pull plates 42 1 are rotatably connected with push-pull rods 422, the inner sides of the two sets of push-pull rods 422 are respectively fixedly connected to the outer walls of the two push-pull rod connecting shafts 419, the outer sides of the front sides of the two push-pull plates 421 are respectively fixedly connected with particle board connecting plates 424, the front sides of the two particle board connecting plates 424 are both extended to the inner wall of the lower bin outer frame 311 through the push-pull groove 318 and are both fixedly connected with the particle board body 425, and the outer walls of the two particle board connecting plates 424 are respectively slidably connected to the inner walls of the two push-pull grooves 318;

[0046] When it is necessary to crush larger masterbatch, the motor 411 is first started, and the motor drives the turntable 414 to rotate. The rotation of the turntable 414 is transmitted to the second turntable 416 through the crawler belt 415, so that the rotating rods 418 on the inner walls of the two C-shaped frames 412 rotate synchronously. As the rotating rods 418 rotate, the push-pull rod connecting shaft 419 is driven to rotate. The rotation of the push-pull rod connecting shaft 419 drives the push-pull rod 422 to move back and forth, so that the push-pull plate 421 slides under the guidance of the particle board slide plate 4111. The sliding of the push-pull plate 421 drives the particle board body 425 to squeeze inward to crush the masterbatch. The crushed masterbatch falls into the lower hopper outer frame 311 to complete the crushing process. The design of the entire crushing mechanism 4 ensures the continuity and efficiency of the crushing process, while also ensuring the safety of operation.

[0047] In addition, the present invention also relates to a recycled plastic particle granulation processing masterbatch processing equipment and a processing method, comprising the following steps:

[0048] Step 1: The masterbatch is transported to the top of the lower bin 3 by the feeder 5;

[0049] Step 2: Adjust the conveying speed of the feeder 5 to ensure that the masterbatch enters the lower bin 3 evenly;

[0050] Step 3: According to the type and particle size of the masterbatch, the hydraulic push rod 324 on the control panel 321 is operated to make the push block 325 and the push plate 326 work together, and the cylindrical slider 328 is pushed and slid through the two inclined slide grooves 327, so that the discharge port adjustment plate 3211 performs corresponding opening and closing actions, thereby controlling the size of the discharge port;

[0051] Step 4: The opening and closing degree of the discharge port adjustment plate 3211 determines the discharge rate and amount of the masterbatch;

[0052] Step 5: In order to ensure the smoothness of the material unloading process, when the push plate 326 moves, the two lifting rods 3212 will rise and fall synchronously, and the lifting block 3213 will move up and down in the slide groove 314 accordingly, ensuring that the plate 3214 pushes the hub 3215 on the beveled surface of the plate 3214 through the beveled surface, thereby pushing the cylindrical push rod 3218 to push and pull, and then pushing the sliding plate 315 to rotate, and the flow rate of the masterbatch is controlled by the rotation angle of the sliding plate 315;

[0053] Step 6: Through this design, the feeding rate and amount of masterbatch can be accurately controlled to adapt to masterbatch of different types and particle sizes, ensuring the efficiency and stability of the granulation process;

[0054] Step 7: During the feeding process, if the masterbatch is too large and needs to be crushed, the crushing mechanism 4 will start to crush the large masterbatch particles to ensure that they can pass through the feeding port smoothly;

[0055] Step 8: The crushing effect of the crushing mechanism 4 directly affects the quality and efficiency of granulation, so its working state needs to be monitored and adjusted in real time.

[0056] Working principle: When the masterbatch needs to be fed into the granulator 1 for hot melting, the masterbatch is first conveyed to the top of the feed bin 3 through the feeder 5. When the masterbatch needs to be screened according to its size, the conveying speed of the feeder 5 is first adjusted to ensure that the masterbatch enters the feed bin 3 evenly. Then, according to the type and particle size of the masterbatch, the hydraulic push rod 324 on the control panel 321 is operated to make the push block 325 and the push plate 326 work together, and the cylindrical slider 328 is pushed by the two inclined slide grooves 327 to slide, so that the feed port adjustment plate 3211 performs corresponding opening and closing actions, thereby controlling the size of the feed port and the opening and closing range of the feed port adjustment plate 3211. The degree determines the feeding rate and amount of the masterbatch. In addition, in order to ensure the smooth feeding process, when the push plate 326 moves, the two lifting rods 3212 will rise and fall synchronously, and the lifting block 3213 will move up and down in the slide groove 314 accordingly, ensuring that the plate 3214 pushes the wheel hub 3215 on the beveled surface of the plate 3214 through the beveled surface, thereby pushing the cylindrical push rod 3218 to push and pull, and then pushing the sliding plate 315 to rotate, and the flow rate of the masterbatch is controlled by the rotation angle of the sliding plate 315. Through this design, the feeding rate and amount of the masterbatch can be accurately controlled to adapt to masterbatches of different types and particle sizes, ensuring the efficiency and stability of the granulation process;

[0057] When it is necessary to crush larger masterbatch, the motor 411 is first started, and the motor drives the turntable 414 to rotate. The rotation of the turntable 414 is transmitted to the second turntable 416 through the crawler belt 415, so that the rotating rods 418 on the inner walls of the two C-shaped frames 412 rotate synchronously. As the rotating rods 418 rotate, the push-pull rod connecting shaft 419 is driven to rotate. The rotation of the push-pull rod connecting shaft 419 drives the push-pull rod 422 to move back and forth, so that the push-pull plate 421 slides under the guidance of the particle board slide plate 4111. The sliding of the push-pull plate 421 drives the particle board body 425 to squeeze inward to crush the masterbatch. The crushed masterbatch falls into the lower hopper outer frame 311 to complete the crushing process. The design of the entire crushing mechanism 4 ensures the continuity and efficiency of the crushing process, while also ensuring the safety of operation.
