[0002] Plastic granulation is a process of plastic mechanical processing. In the process of plastic granulation, it is necessary to master the plastic granulation skills according to the performance of the machine and practical exploration, so as to continuously improve the quality and process of plastic products. Plastic granulation is often used in the waste recycling of plastic products and the use of plastic renewable resources. In modern society, this process is becoming more and more mature, but the existing plastic granulation equipment has some shortcomings, such as: Application number: CN202310454887.0 is a high-efficiency plastic granulator. The device cuts plastic granules with a cutter, and then the granules move downward in a guide groove and fall into a forming box, and then fall into a collection box for collection. The cutting effect is good, and the cutting force on the plastic granules is uniform. All granules are cut at the same time, and the cut plastic granules will not stick together, with high consistency, which is convenient for subsequent processing steps; However, in actual use, when the equipment is granulating different types of plastic raw materials, it may be difficult to mix the various plastic raw materials evenly, resulting in difficulty in forming relatively uniform particles during the granulation process, resulting in failure of plastic granulation.

The cooling device cools the plastic raw material inside the discharge pipe 23, so that the third auger shaft 32 pushes the plastic raw material into the extrusion tube 37, and the plastic raw material is formed into a line shape through the extrusion groove 36 provided inside the extrusion tube 37. At the same time, the fourth sprocket 31 also drives the rotating blade 39 to rotate, so that the rotating blade 39 cuts the plastic raw material that has been extruded by the extrusion tube 37 into granules, so that the plastic granules fall into the placement groove 40, completing the plastic granulation work. When the heating bin 1 is heating, heat flow can be added for heating through the heating pipe provided inside the heating bin 1.

[0028] Working principle: When using the high-uniformity plastic granulation extrusion molding equipment, first make the driving motor 3 rotate forward, thereby driving the first bevel gear 4 to rotate, and the second first bevel gear 4 will drive the second bevel gear 5 and the ratchet group set at the left end of the second bevel gear 5 to engage, so that the second bevel gear 5 can drive the feeding mechanism to operate, and since the ratchet direction of the ratchet group set at the left end of the second bevel gear 5 is opposite to the ratchet direction of the ratchet group at the right end of the third bevel gear 24 and the ratchet group inside the second device shell 20, the ratchet group at the right end of the third bevel gear 24 and the ratchet group inside the second device shell 20 will be disconnected, so that the discharging mechanism will not operate, and then the heating bin 1 will be heated, so that the plastic raw material inside the heating bin 1 is melted when the heating bin 1 is heated, and at the same time, the driving motor 3 will also drive the crushing mechanism to operate, so that the plastic raw material inside the heating bin 1 is crushed and mixed by the crushing mechanism; When the ratchet group at the left end of the second bevel gear 5 is engaged, that is, the first ratchet 6 is engaged with the second ratchet 7, the rotation of the second ratchet 7 drives the spring shaft 8 and the first driving shaft 9 to rotate, so that the first driving shaft 9 drives the active bevel gear 10 to rotate, thereby making the active bevel gear 10 drive the driven bevel gear 11 to rotate, so that the driven bevel gear 11 drives the first auger shaft 12 to rotate, so that the first auger shaft 12 rotates inside the feed port 14, so that the first auger shaft 12 drives the plastic raw material into the heating bin 1, and at the same time the driving motor 3 drives the active gear 15 to rotate, so that the active gear 15 drives the driven gear 16 to rotate, thereby driving the three sets of crushing shafts 17 to rotate at the same time. Since the connecting shaft 18 is provided at the bottom of the active gear 15, the connecting shaft 18 will also drive the stirring shaft 19 to rotate, so that the stirring shaft 19 and the crushing shaft 17 rotate at the same time to mix the plastic raw material inside the heating bin 1; When the driving motor 3 rotates in the reverse direction, the ratchet group at the left end of the first bevel gear 4 will be disengaged, that is, the first ratchet 6 is disengaged from the ratchet groove inside the second ratchet 7, and the second ratchet 7 retreats under the drive of the spring shaft 8, thereby stopping the rotation of the feeding mechanism. At this time, the ratchet group at the right end of the third bevel gear 24 and the ratchet group inside the second device shell 20 will be engaged, so that the bottom of the connecting shaft 18 drives the second auger shaft 22 to rotate through the ratchet group, so that the mixed raw materials pass through the second auger shaft 22 into the discharge pipe 23, and at the same time, the crushing mechanism will also rotate in the reverse direction, crushing and mixing the plastic raw materials inside the heating bin 1 again until the plastic raw materials enter the discharge pipe 23; When the driving motor 3 rotates in the opposite direction, the third bevel gear 24 will drive the second driving shaft 25 and the first sprocket 26 to rotate through the ratchet group, so that the first sprocket 26 drives the second sprocket 28 to rotate through the first chain 27, thereby making the second sprocket 28 drive the third sprocket 29 to rotate, and the third sprocket 29 will also drive the fourth sprocket 31 to rotate through the second chain 30, thereby making the third sprocket 29 drive the third auger shaft 32 to rotate, so that the plastic raw material entering the discharge pipe 23 is driven by the third auger shaft 32 to move to the left end, and at the same time, the plastic raw material connected to the discharge pipe 23 is started. The cooling device cools the plastic raw material inside the discharge pipe 23, so that the third auger shaft 32 pushes the plastic raw material into the extrusion tube 37, and the plastic raw material is formed into a line shape through the extrusion groove 36 provided inside the extrusion tube 37. At the same time, the fourth sprocket 31 also drives the rotating blade 39 to rotate, so that the rotating blade 39 cuts the plastic raw material that has been extruded by the extrusion tube 37 into granules, so that the plastic granules fall into the placement groove 40, completing the plastic granulation work. When the heating bin 1 is heating, heat flow can be added for heating through the heating pipe provided inside the heating bin 1.
