The pretreatment mechanism 5 is located between the discharge port at the bottom of the cleaning tank 3 and the inlet at one end of the feeding mechanism 6. During the feeding process of plastic granules, plastic granules are added into the cleaning tank 3. The stirring and cleaning mechanism 4 stirs and cleans the plastic granules in the cleaning tank 3. After stirring and cleaning, the pretreatment mechanism 5 conveys and dries the plastic granules, allowing the processed plastic granules to enter the feeding mechanism 6.

The pretreatment mechanism 5 includes a U-shaped frame 51, which is fixedly installed on the upper surface of the base plate 1. A hopper is provided at one end of the U-shaped frame 51 near the feeding mechanism 6. The hopper is vertically aligned with the feed inlet at one end of the feeding mechanism 6. Through the hopper, the processed plastic granules can enter the feed inlet of the feeding mechanism 6. A conveying mechanism 7 and a drying mechanism 8 are respectively provided on the U-shaped frame 51. By setting the conveying mechanism 7 and the drying mechanism 8, the conveying mechanism 7 can convey the plastic granules after stirring and cleaning, and the drying mechanism 8 can dry the plastic granules during the conveying process. The conveying mechanism 7 includes two conveying rollers 71, which are symmetrically mounted at the ends of the U-shaped frame 51. A conveyor belt 72 is driven between the two conveying rollers 71. A toothed pulley 73 is fixedly mounted at one end of each of the two conveying rollers 71, and a drive belt 74 is driven between the two toothed pulleys 73. A servo motor 75 is fixedly mounted at one end of the U-shaped frame 51. The drive output end of the servo motor 75 is fixedly connected to one end of one of the conveying rollers 71. By starting the servo motor 75... 5. The drive shaft of the servo motor 75 can rotate one conveyor roller 71. Under the action of the two first toothed pulleys 73 and the first transmission toothed belt 74, the two conveyor rollers 71 can rotate synchronously and in the same direction, so that the conveyor belt 72 can transport. The conveyor belt 72 can transport the plastic granules after stirring and cleaning. Two baffles 76 are fixedly installed inside the U-shaped frame 51. The two baffles 76 are symmetrically distributed at the edge of the upper surface of the conveyor belt 72. By setting the two baffles 76, the baffles 76 can prevent the plastic granules on the conveyor belt 72 from falling off. The drying mechanism 8 includes a first rotating roller 81, a second rotating roller 83, and a heating air unit 89.

Two first rotating rollers 81 are provided, and several paddles 82 are fixedly mounted on the outer wall of the first rotating roller 81. By driving the first rotating roller 81 to rotate, the first rotating roller 81 can cause the paddles 82 to rotate, and the paddles 82 can agitate the plastic particles on the conveyor belt 72, thus dispersing the plastic particles during the conveying process. The second rotating roller 83 is located between the two first rotating rollers 81, and the second rotating roller 83 has detachable... The sponge 84 is installed and fixed to the outer wall of the second rotating roller 83 with waterproof adhesive. During disassembly, the sponge 84 can be cut open with a blade. During installation, waterproof adhesive is applied to the inner ring of the sponge 84 or the outer wall of the second rotating roller 83, and the sponge 84 is placed on the outer wall of the second rotating roller 83. The sponge 84 is located on the upper surface of the conveyor belt 72 with gaps. When plastic particles on the conveyor belt 72 pass through the sponge 84, the sponge 84 can absorb the cleaning water attached to the plastic particles.

[0021] A drive shaft 9 is rotatably mounted on one side of the U-shaped frame 51. A second toothed pulley 91 is fixedly mounted on the other end of one of the conveyor rollers 71 and on one end of the drive shaft 9. A second drive belt 92 is installed between the two second toothed pulleys 91. A drive gear 93 is fixedly mounted on the middle of the drive shaft 9 and on one end of the second rotating roller 83. The two drive gears 93 mesh together. When the conveyor roller 71 rotates, it can rotate the drive shaft 9 through the two second toothed pulleys 91 and the second drive belt 92. The drive shaft 9 can then rotate the second rotating roller 83 through the two drive gears 93. The rotation direction of the second rotating roller 83 and the sponge 84 is opposite to the rotation direction of the conveyor roller 71, thus not affecting the plastic... The material particles move toward one side of the feeding mechanism 6. One end of each of the two No. 1 rotating rollers 81 is fixedly equipped with a No. 3 toothed pulley 94, and a No. 3 transmission toothed belt 95 is installed between the two No. 3 toothed pulleys 94. One end of the No. 2 rotating roller 83 and one end of one of the No. 1 rotating rollers 81 are fixedly equipped with a No. 4 toothed pulley 96, and a No. 4 transmission toothed belt 97 is installed between the two No. 4 toothed pulleys 96. When the No. 2 rotating roller 83 rotates, it can cause one No. 1 rotating roller 81 to rotate through the two No. 4 toothed pulleys 96 and the No. 4 transmission toothed belt 97. One No. 1 rotating roller 81 can cause the other No. 1 rotating roller 81 to rotate synchronously and in the same direction through the two No. 3 toothed pulleys 94 and the No. 3 transmission toothed belt 95.

[0022] Working principle: During the plastic granule processing, after the plastic granules are stirred and cleaned, they are discharged downward through the bottom of the cleaning tank 3 and fall onto the conveyor belt 72. At the same time, the operator starts the servo motor 75 and the heating air unit 89. The drive shaft of the servo motor 75 causes one conveyor roller 71 to rotate. Under the action of the two first toothed pulleys 73 and the first transmission toothed belt 74, the two conveyor rollers 71 rotate synchronously and in the same direction. The two conveyor rollers 71 cause the conveyor belt 72 to transport the plastic granules after stirring and cleaning. Meanwhile, one of the conveying rollers 71 rotates the drive shaft 9 through two second-order toothed pulleys 91 and a second-order transmission toothed belt 92. The drive shaft 9 rotates the second-order rotating roller 83 and the sponge 84 through two transmission gears 93. The second-order rotating roller 83 rotates one first-order rotating roller 81 through two fourth-order toothed pulleys 96 and a fourth-order transmission toothed belt 97. The first-order rotating roller 81 rotates the other first-order rotating roller 81 synchronously and in the same direction through two third-order toothed pulleys 94 and a third-order transmission toothed belt 95. At this time, multiple paddles 82 on the two first-order rotating rollers 81 rotate circumferentially. The circumferential rotation of the paddles 82 disperses the plastic particles during the conveying process. The sponge 84 continuously contacts the plastic particles during the rotation process and absorbs the cleaning water attached to the plastic particles. At the same time, under the action of the extrusion plate 88, the cleaning water absorbed by the sponge 84 flows into the water collection box 85 along the extrusion plate 88 and the water inlet trough 87. When the plastic granules during the conveying process reach the bottom of the heating air unit 89, the high-temperature airflow generated by the heating air unit 89 dries the plastic granules. The dried plastic granules fall into the feed port of the feeding mechanism 6 through the hopper at the end of the U-shaped frame 51. The auger of the feeding mechanism 6 completes the feeding of the plastic granules, allowing them to enter the hot melt injection molding equipment.
