The input end of the second motor 47 is electrically connected to the output end of the controller 9.

[0032] The working principle of this utility model is as follows:

[0033] When using this masterbatch extrusion granulation equipment, the melting temperature and melting rate of the masterbatch can be determined according to its material. The masterbatch has different melting temperature and melting rate. At this time, the masterbatch that needs to be colored can be fed into the extrusion cylinder 2 through the feed cylinder 5 in a certain proportion.

[0034] At this time, the controllable controller 9 and the second motor 47 are running. The output shaft of the second motor 47 rotates, which in turn drives the drive spline shaft 45 to rotate, which in turn drives the two driven spline shafts 46 to rotate in the same direction, which in turn drives the two screw rods 41 to rotate. At this time, the masterbatch entering the extrusion cylinder 2 will move to the left and be squeezed and mixed during the conveying process. The external heating oil circulation equipment discharges the circulating hot oil into the heating box 31 on the left side to heat the temperature of a section of the left crushing tooth 42.

[0035] Simultaneously, the controller 9 is adjusted, and the two temperature sensors 7 operate to measure the temperature inside the two heating boxes 31 in real time. When the temperature inside the two heating boxes 31 is lower than a certain temperature, the controller 9 is adjusted, and the first motor 387 operates. The output shaft of the first motor 387 rotates, which in turn drives the front lead screw 381 to rotate. This, in turn, drives the rear lead screw 381 to rotate through the sprocket 384 and chain 385, which in turn drives the moving frame 382 to adjust its left and right position. When the heating oil in the heating box 31 needs to be replaced, the moving frame 382 can be adjusted to move to the right, which in turn drives the two drain plates 39 to move to the right inside the heating box 31. At this time, the lower-temperature hot oil in the heating box 31 can be driven to the right and discharged through the liquid outlet pipe 36. At the same time, the liquid inlet pipe 37 discharges the hot oil of suitable temperature into the left side of the interior of the heating box 31 until the hot oil is completely replaced.

[0036] At this point, the controller 9 can be adjusted, and the two electric valves 35 will open. At this time, the internal circulation pipe 34 will connect the left and right sides of the heating box 31. At this time, the two drain plates 39 can be adjusted to reset. During the reset, under the influence of pressure, the hot oil on the left side of the drain plate 39 can be drawn into the right side of the drain plate 39 through the internal circulation pipe 34. In this way, the temperature in the two heating boxes 31 is maintained at a relatively suitable temperature in real time. It is worth noting that the temperature range of the hot oil in the left heating box 31 is greater than that of the right heating box 31.

[0037] When the two sets of right-side crushing teeth 43 are crushing the color masterbatch for the first time, the right-side heating box 31 provides an appropriate temperature so that the color masterbatch is crushed and mixed evenly. When the color masterbatch moves to the right-side crushing tooth 43 section, the left-side heating box 31 provides a higher temperature so that the color masterbatch is melted and mixed, completing the color matching operation.

[0038] Then the molten masterbatch continues to move to the left. When it reaches the cooling box 10, the external cooling equipment lowers the temperature inside the cooling box 10 in real time. The masterbatch passing through the cooling box 10 is cooled and then discharged to the right into the pelletizer 6. At this time, the controller 9 can be adjusted to start the pelletizer 6, which cuts the cooled plastic strip into pellets and discharges the pellets, completing the extrusion granulation operation.

[0039] It is worth noting that the core chip of the controller 9 disclosed in the above embodiments is a single-chip microcomputer, specifically the STC89C52. The electric valve 35, the first motor 387, the second motor 47, the pelletizer 6, the temperature sensor 7, and the exhaust valve 8 can be freely configured according to the actual application scenario. It is recommended that the electric valve 35 be a D941H electric butterfly valve, the first motor 387 be a 130BL series servo motor, the second motor 47 be a GH32-1500-10S gear reduction motor, the pelletizer 6 be an LQ-900 gantry pelletizer, the temperature sensor 7 be a PT100 temperature sensor, and the exhaust valve 8 be an AEV-B12P high-temperature automatic exhaust valve. The controller 9 controls the operation of the electric valve 35, the first motor 387, the second motor 47, the pelletizer 6, and the temperature sensor 7 using methods commonly used in the prior art.

[0040] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
