Description

Technical Field

[0001] The invention relates to the technical field of plastic masterbatch processing, and in particular to a plastic masterbatch continuous processing device and method. Background Art

[0002] The ink method is a production method that uses ink color paste in the production of masterbatch, that is, through three-roll grinding, a low-molecular protective layer is coated on the surface of the pigment, the fine color paste after grinding is mixed with the carrier resin, and then plasticized by a two-roll plasticizer, and finally granulated by a single-screw or twin-screw extruder. Under the current conditions, the color paste and the carrier resin need to be fully mixed and completely mixed.

[0003] Existing processing equipment, such as a pelletizing device for plastic masterbatch production disclosed in announcement number CN221249468U, when the stirring rod stirs the plastic particles on the collecting plate, the cam rotates to drive the collecting plate to reciprocate so that the collecting plate vibrates, further improving the separation effect. At the same time, the plastic particles can be continuously discharged and collected under the action of the inclined collecting plate and the first and second discharge ports. However, there is a lack of supporting pretreatment for various raw materials used to make plastic masterbatches, especially there are many types of plastic masterbatch raw materials, and there are huge differences in volume, hardness and density. Similarly, a masterbatch plastic pellet feeding device disclosed in announcement number CN219429196U replaces the traditional manual feeding method with an automated means, and has the advantages of high work efficiency, relatively accurate feeding amount and good feeding continuity, but fails to deeply crush the plastic masterbatch raw materials, which leads to the fact that plastic masterbatch raw materials of different sizes are easily blocked and accumulated in the feeding structure, and it is more difficult to achieve effective mixing of various plastic masterbatch raw materials, which not only affects the mixing uniformity, but also easily causes the masterbatch to break during the cutting process.

[0031] It should be noted that the specific model and specifications of the motor need to be selected and determined based on the actual specifications of the device, and the specific selection calculation method adopts the existing technology in this field, so it will not be repeated.

[0032] The present invention can be explained by the following operation mode: First, the plastic masterbatch raw material is introduced into the upper cavity 101 through the feed port 104, and the first motor 3 and the second motor 4 are controlled to be turned on. The output end of the first motor 3 drives the boosting convex rod 30 to rotate, so as to apply pressure to the boosting triangle block 8 and the return spring 6, so that the guide block 7 moves back and forth along the guide long hole 5. The guide block 7 drives the booster 9 to rise and fall in the upper cavity 101 through the upper connecting rod 10, and the plastic masterbatch raw material located in the upper cavity 101 is pressurized and crushed. The crushed plastic masterbatch raw material enters the middle cavity 102 through the discharge port 105. In this process, various plastic masterbatch raw materials are preliminarily crushed to ensure that the crushed plastic masterbatch raw materials can enter the middle cavity 102; Secondly, the up-and-down moving supercharging member 9 drives the rolling member 12 to move radially through the lower connecting rod 13 to roll and crush the plastic masterbatch raw materials in the middle cavity 102, so that the crushed plastic masterbatch raw materials enter the discharge pipe 106 and evenly enter the lower cavity 103 under the action of the bulk material boss 15. In this process, various plastic masterbatch raw materials can be further rolled and crushed, so that the crushed plastic masterbatch raw materials can enter the lower cavity 103; Then, the output end of the second motor 4 drives the ball screw 14 to rotate, and under the action of centrifugal force, the limit block 21 has a tendency to expand and move outward. The limit block 21 pulls the stirring shaft 22 through the traction rod 23 to repeatedly open and close, so as to stir and drive the plastic masterbatch raw material in the lower chamber 103. The lifting nut 17 that moves up and down drives the sealing booster plate 19 to move up and down along the discharge pipe 106 through the guide rod 18, and squeezes the plastic masterbatch raw material in the lower chamber 103 during the downward movement, so that the plastic masterbatch raw material is discharged from the lower chamber 103 through the discharge port 107. The plastic masterbatch raw material is mixed by fully stirring and crushing the plastic masterbatch raw material, and then the plastic masterbatch raw material is discharged out of the body 1 in an orderly manner through pressurized driving; Finally, the output end of the first motor 3 drives the traction turntable 24 to rotate, and the traction turntable 24 drives the reciprocating rack 25 to move back and forth through the synchronous connecting rod 26. The reciprocating rack 25 drives the driven shaft 27 to deflect back and forth through the reciprocating gear 28. The driven shaft 27 drives the cutter 29 to deflect synchronously to cut the plastic masterbatch raw materials discharged from the discharge port 107, so that the columnar structure of the plastic masterbatch raw materials is formed into fragments.
