[0042] See also Figure 6 , Figure 7 , Figure 8 and Fig.12The side of the rotating rod 3 518 away from the rotating rod 4 519 is fixedly connected with the gear 8 521, the inner ring of the gear 8 521 is provided with a small bevel gear 1, the outer side of the small bevel gear 1 is meshed with the bevel gear 3 523, the side of the bevel gear 3 523 away from the rotating rod 3 518 is rotatably connected with the adsorption block 524, the side of the bevel gear 3 523 away from the gear 8 521 is provided with a gear 9 522, the inner ring of the gear 9 522 is provided with a small bevel gear 2, the small bevel gear 2 is meshed with the bevel gear 3 523, the gear 9 The outer side of 522 is meshed with gear five 514, and the center of gear five 514 is fixedly connected with rotating rod five 516, the end of rotating rod five 516 away from water tank 6 is rotatably connected with connecting pipe one 512, the end of connecting pipe one 512 away from water tank 6 is fixedly connected to connecting plate two 508, rotating rod five 516 is rotatably connected to box body one 501, an inner ratchet is provided on the inner side of gear nine 522, and an outer ratchet is provided at the connection between rotating rod three 518 and gear nine 522, and the inner ratchet is meshed with the outer ratchet.

[0043] Specifically, after the staff starts the device, the motor 801 will start to control the shaft 502 to rotate forward, the rotation of the shaft 502 will drive the gear 1 504 to rotate, the rotation of the gear 1 504 will drive the gear 2 505 to rotate, the rotation of the gear 2 505 will drive the shaft 1 503 to rotate, the rotation of the shaft 1 503 will drive the gear 3 509 to rotate, and thus complete the acceleration, the rotation of the gear 3 509 will drive the gear 7 517 to rotate, the rotation of the gear 7 517 will drive the gear 6 515 to rotate, and then the rotating rod 4 519 will rotate synchronously, so that The screw 208 connected to the rotating rod 4 519 rotates, and the rotation direction of the screw 208 is opposite to the rotation direction of the gear 7 517. When the gear 7 517 rotates, it will also synchronously drive the rotating rod 3 518 to rotate, thereby driving the gear 8 521 to rotate. The rotation of the gear 8 521 will drive the adsorption block 524 to rotate. Since the adsorption block 524 is not fixed at this time, the adsorption block 524 will rotate synchronously with the rotation of the rotating rod 3 518. At the same time, the gear 9 522 will also rotate synchronously with the rotating rod 3 518, and the outer side of the gear 9 522 is meshed with a tooth. The gear 514 will restrict the rotation of the gear 9 522, but due to the inner ratchet inside the gear 9 522 and the outer ratchet on the rotating rod 3 518, the gear 9 522 can only reverse freely, so that the gear 9 522 can drive the gear 5 514 to rotate synchronously, and the rotation of the gear 5 514 will drive the rotating rod 5 516 to rotate synchronously, so that the screw 208 connected to the rotating rod 5 516 can rotate synchronously. At this time, the rotation directions of the two screws 208 are the same, which can smoothly convey the plastic and improve the efficiency. When the motor 801 controls When the control shaft 502 is reversed, the rotating rod four 519 will start to reverse synchronously under the action of the series linkage, and at this time the electromagnet 525 starts to generate magnetic force to adsorb the adsorption block 524. The adsorption block 524 will be fixed after adsorption, thereby making the bevel gear three 523 rotate around the adsorption block 524, and then driving the gear nine 522 to rotate through the bevel gear three 523, so that the rotation direction of the gear nine 522 does not change twice, thereby making the two screws 208 rotate in opposite directions. At this time, the screw 208 has a stronger shearing and extrusion effect on the engineering plastic, thereby achieving more refined mixing.

[0044] See also Fig. 9 and Fig.10The extrusion tube 2 includes a pipe 204 fixedly connected to the carrying box 1, a screw 208 is rotatably connected inside the pipe 204, two screws 208 are respectively fixedly connected to the rotating rod 4 519 and the rotating rod 5 516, a filter plate 207 is connected to the end of the screw 208 away from the transmission box 5, a diverter plate 206 is connected to the end of the filter plate 207 away from the screw 208, a water outlet 209 is fixedly connected to the end of the screw 208 away from the transmission box 5, the water outlet 209 penetrates the diverter plate 206, and the end of the diverter plate 206 away from the transmission box 5 is connected to the extrusion port 20 5.

A cooling box 201 is provided on the side of the secondary heating box 202 away from the transmission box 5, and a primary heating box 203 is provided on the side of the secondary heating box 202 away from the cooling box 201. By setting a screw 208, water will continuously flow inside the screw 208, and the screw 208 can be cooled by the water flow to prevent the engineering plastic from overheating when in contact with the screw 208, thereby avoiding the degradation and performance deterioration of the engineering plastic.

[0045] Specifically, the engineering plastic will continuously move forward under the rotation of the screw 208. When the engineering plastic moves to the primary heating box 203, the primary heating box 203 will heat the engineering plastic in the pipe 204 for the first time to eliminate the internal stress of the engineering plastic, making the engineering plastic softer. At the same time, the temperature of the primary heating is not high, so that the engineering plastic will not melt and stick prematurely after entering the pipe 204. When the engineering plastic moves to the secondary heating box 202, the engineering plastic will be further heated, and different plastics can be mixed with each other to improve the consistency of the production. When the engineering plastic moves to the cooling box 201, the cooling box 201 will cool the engineering plastic, so that the engineering plastic can be quickly solidified after extrusion, thereby maintaining its shape and size. At the same time, water will continuously flow inside the screw 208, and the water flow can cool the screw 208 to prevent the engineering plastic from overheating when it contacts the screw 208, thereby avoiding the degradation and performance deterioration of the engineering plastic.

[0050] Specifically, after the device starts working, the water in the water tank 6 is transported to the box body 501 through the connecting pipe 802, and then transported to the delivery pipe 510 through the pipeline in the box body 501, and then flows from the delivery pipe 510 to the fixed plate 506, and finally transported to the inside of the connecting pipe 1 512 and the connecting pipe 2 513 through the connecting plate 2 508.

[0051] See also Fig.14 , the side of bevel gear three 523 away from rotating rod three 518 is fixedly connected to limit tube 529, and a limit rod 1 527 is arranged on the inner side of limit tube 529, and the limit rod 1 527 is located at the center of bevel gear three 523, and a sleeve 528 is movably connected to the inner side of limit tube 529, and an end of sleeve 528 away from bevel gear three 523 is fixedly connected to adsorption block 524, and a spring 1 526 is fixedly connected between adsorption block 524 and bevel gear three 523, and spring 1 526 is located on the outer side of limit rod 1 527. By setting spring 1 526, adsorption block 524 and limit tube 529 are tightly attached when electromagnet 525 is not energized, and the rotation of adsorption block 524 will not touch electromagnet 525 at this time, and when electromagnet 525 is energized, adsorption block 524 is adsorbed and will not affect the contact between adsorption block 524 and bevel gear three 523 through limit rod 1 527.

[0052] Specifically, the motor 801 controls the rotating shaft 502 to reverse and energizes the electromagnet 525 at the same time, so that the electromagnet 525 can generate magnetic force, and then when the adsorption block 524 rotates to the top of the electromagnet 525, the electromagnet 525 will adsorb the adsorption block 524, so that the adsorption block 524 cannot move, and then the bevel gear three 523 can rotate around the adsorption block 524 to complete the subsequent linkage, and by setting the spring one 526, the adsorption block 524 is tightly attached to the limiting tube 529 when the electromagnet 525 is not energized. At this time, the rotation of the adsorption block 524 will not touch the electromagnet 525. When the electromagnet 525 is energized, the adsorption block 524 is adsorbed and the contact between the adsorption block 524 and the bevel gear three 523 is not affected by the limiting rod one 527.

[0053] Working principle of the present invention: after the staff starts the device, the motor 801 will start to control the shaft 502 to rotate forward, the rotation of the shaft 502 will drive the gear 1 504 to rotate, the rotation of the gear 1 504 will drive the gear 2 505 to rotate, the rotation of the gear 2 505 will drive the shaft 1 503 to rotate, the rotation of the shaft 1 503 will drive the gear 3 509 to rotate, and thus complete the acceleration, the rotation of the gear 3 509 will drive the gear 7 517 to rotate, the rotation of the gear 7 517 will drive the gear 6 515 to rotate, and then the rotating rod 4 519 will rotate synchronously, so that the screw 208 connected to the rotating rod 4 519 can rotate. The screw 208 rotates, and the rotation direction of the screw 208 is opposite to that of the gear seven 517. While the gear seven 517 rotates, it also synchronously drives the rotating rod three 518 to rotate, thereby driving the gear eight 521 to rotate. The rotation of the gear eight 521 drives the adsorption block 524 to rotate. Since the adsorption block 524 is not fixed at this time, the adsorption block 524 will rotate synchronously with the rotation of the rotating rod three 518. At the same time, the gear nine 522 will also rotate synchronously with the rotating rod three 518. The outer side of the gear nine 522 is meshed with the gear five 514. The gear five 514 will limit the rotation of the gear nine 522. However, since the inner part of the gear nine 522 is The inner ratchet on the side and the outer ratchet on the rotating rod three 518 make the gear nine 522 only able to reverse freely, so that the gear nine 522 can drive the gear five 514 to rotate synchronously, and the rotation of the gear five 514 will drive the rotating rod five 516 to rotate synchronously, so that the screw 208 connected to the rotating rod five 516 can rotate synchronously. At this time, the rotation directions of the two screws 208 are the same, which can smoothly convey the plastic and improve efficiency. When the motor 801 controls the rotating shaft 502 to reverse, the rotating rod four 519 will start to reverse synchronously under the action of the series linkage drive, and at this time the electromagnet 525 starts to generate magnetic force to the adsorption block 524 After the adsorption is carried out, the adsorption block 524 will be fixed, so that the bevel gear three 523 rotates around the adsorption block 524, and then the bevel gear three 523 drives the gear nine 522 to rotate, so that the rotation direction of the gear nine 522 does not change twice, and then the two screws 208 rotate in opposite directions. At this time, the shearing and extrusion effects of the screw 208 on the engineering plastic are stronger, thereby achieving more refined mixing. Under the rotation of the screw 208, the engineering plastic will continue to move forward. When the engineering plastic moves to the primary heating box 203, the primary heating box 203 will perform primary heating on the engineering plastic in the pipe 204 to eliminate the internal stress of the engineering plastic.The engineering plastic becomes softer, and the temperature of the initial heating is not high, so that the engineering plastic will not melt and stick prematurely after entering the pipe 204. When the engineering plastic moves to the secondary heating box 202, the engineering plastic will be further heated, and different plastics can be mixed with each other to improve the consistency of the production. When the engineering plastic moves to the cooling box 201, the cooling box 201 will cool the engineering plastic, so that the engineering plastic can be quickly solidified after extrusion, thereby maintaining its shape and size. At the same time, water will continue to flow inside the screw 208, and the water flow can be used to A cooling treatment is performed to prevent the engineering plastic from overheating when in contact with the screw 208, thereby avoiding the degradation and performance deterioration of the engineering plastic. After the device starts working, the water in the water tank 6 is transported to the box body 501 through the connecting pipe 802, and then the water is transported to the delivery pipe 510 through the pipeline in the box body 501, and then flows from the delivery pipe 510 to the fixed plate 506, and finally transported to the inside of the connecting pipe 1 512 and the connecting pipe 2 513 through the connecting plate 2 508. At the same time, the heat generated by the motor 801 will be transferred to the water tank 6 by heat conduction, and the motor 801 can be cooled by the water tank 6.
