Description

Technical Field

[0001] The invention relates to the technical field of PE leg wire extrusion, in particular to an insulating PE leg wire extrusion production device and a method thereof. Background Art

[0002] Extrusion molding is also called extrusion molding in plastic processing. In non-rubber extruder processing, the extrusion that uses hydraulic pressure on the mold itself is called extrusion. It refers to a processing method in which the material passes through the action between the extruder barrel and the screw, while being heated and plasticized, and is pushed forward by the screw through the die to form various cross-section products.

[0003] During the extrusion production of insulating PE leg wires, since the surface of the wire has a certain temperature during extrusion, the surface of the extruded wire will be cooled to improve the smoothness of extrusion. Generally, cooling water is sprayed on the surface of the extruded wire. However, since the surface of the leg wire is soft during extrusion, when cooling water is sprayed on the surface of the extruded wire, the impact force of the cooling water on the surface of the leg wire is too large, causing the surface of the wire to deform, which will affect the quality of the extruded wire.

[0014] The present invention also discloses an insulating PE foot wire extrusion production method, which adopts the above insulating PE foot wire extrusion production equipment, and comprises the following steps: S1: First, plastic particles are poured into the first feeding bin and the second feeding bin, and then the plastic particles enter the main body of the screw extruder through the first feeding bin and the second feeding bin. At this time, the operation of the main body of the screw extruder causes the material to be heated and plasticized while being pushed forward by the screw; S2: The plasticized material is extruded through the extruder head. During this process, the multi-directional jet is activated to increase the fluidity of the air around the extruded footing, so as to fully cool the surface of the extruded footing, so that the surface of the footing is cooled and solidified; S3: As the foot line continues to be extruded, the foot line after the surface is cooled is sprayed by the synchronous spraying part; S4: The cooled insulated PE leg wire is then reeled up using a reel.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1.

By starting the motor to rotate the L-shaped jet chamber along the center of the extruder head, the ejected airflow will be discharged through the second annular chamber, the first rotating chamber, the corrugated telescopic pipe, the L-shaped connecting pipe, and the L-shaped jet chamber. At this time, when the extruder extrudes the foot line, the airflow ejected from the L-shaped jet chamber will blow around the foot line, so as to increase the fluidity of the air on the surface of the foot line. At the same time, the rotation of the L-shaped jet chamber around the foot line realizes the preliminary cooling of the foot line surface in all directions, thereby improving the cooling efficiency of the foot line surface; 2. By setting a synchronous liquid spraying part, when the L-shaped connecting pipe sprays airflow, the air blocking plug loses its shielding on the top of the L-shaped jet chamber. At this time, the airflow will pass through the L-shaped connecting pipe and finally be sprayed out from the L-shaped jet chamber. During the movement of the air blocking plug, the liquid blocking plug moves out between the connecting conduit and the nozzle. When the water pump injects water into the first annular chamber through the liquid spraying pipe, the water flow will pass through the hose, the connecting conduit, the liquid blocking chamber and finally be sprayed out from the nozzle, so that the water flow is sprayed on the surface of the solidified extrusion line for further cooling, thereby realizing the orderly progress of air cooling and water cooling, and preventing the water flow from directly impacting the surface of the extrusion line and causing deformation of the extrusion line.

[0023] In this embodiment: before using the screw extruder body 1, the extruder head 4 is replaced according to the production requirements, and then the pitch-adjusting screw rod 513 is rotated according to the diameter of the extrusion end of the extruder head 4. When the pitch-adjusting screw rod 513 is rotated, the sleeve slider 514 can move along the pitch-adjusting screw rod 513, so that the shift chain 510 drives the L-shaped connecting tube 518 to move through the oblique connecting frame 526, the U-shaped connecting frame 533, the guide plug rod 525, and the clamping plate 519, so that the L-shaped connecting tube 518 moves toward or away from the center of the first rotating warehouse 508, so as to adjust the distance from the L-shaped jet warehouse 520 to the center of the first rotating warehouse 508, so that the L-shaped jet warehouse 520 is flush with the edge of the extrusion end of the extruder head 4, and then the motor 505 is started, and the The operation of the motor 505 drives the transmission spur gear ring 502 to rotate by the transmission gear plate 504, so that the transmission spur gear ring 502 drives the first rotating chamber 508 to rotate, so that the L-shaped jet chamber 520 can rotate along the center of the extruder head 4. When the external blower is in operation, the ejected airflow will be discharged through the second annular chamber 516, the first rotating chamber 508, the bellows telescopic tube 517, the L-shaped connecting tube 518, and the L-shaped jet chamber 520. At this time, when the extruder head 4 extrude the foot line, the airflow ejected from the L-shaped jet chamber 520 will blow around the foot line, so as to increase the fluidity of the air on the surface of the foot line, and at the same time, the rotation of the L-shaped jet chamber 520 around the foot line realizes all-round cooling of the foot line surface, thereby improving the cooling efficiency of the foot line surface.

[0024] Please refer to Figure 2 , Figure 3 , Figure 4 The extrusion head 4 and the first rotating chamber 508 are coaxial in center, and a plurality of L-shaped connecting tubes 518 are provided, and the plurality of L-shaped connecting tubes 518 are distributed at equal distances along the center of the first rotating chamber 508 .

[0025] In this embodiment: this structure is provided to achieve all-round cooling of the foot line surface, and at the same time, each L-shaped jet chamber 520 is at an equal distance from the foot line surface when the first rotating chamber 508 rotates, thereby improving the uniformity of cooling at various positions on the foot line surface.

[0026] Please refer to Figure 4 , Figure 5 , Figure 6 The sleeve slider 514 is provided with a threaded hole matching the pitch-adjusting screw rod 513 , and the shifting link 510 is coaxial with the center of the first rotating bin 508 .

[0027] In this embodiment, by setting this structure, when the sleeve slider 514 moves along the distance-adjusting screw rod 513 , the multiple L-shaped connecting tubes 518 move synchronously and the moving distances are equal.

[0028] Please refer to Figure 1 , Figure 2 , Figure 5 , Figure 7 , Figure 8 The synchronous liquid spraying member includes a first annular bin 507 installed at one end of a side connecting frame 509, a liquid spraying pipe 506 connected to an external water pump is installed on the first annular bin 507, a second rotating bin 511 is rotatably connected to one end of the first annular bin 507 near the shifting link 510, a hose 512 is installed at one end of the second rotating bin 511 near the shifting link 510, a clamping frame 523 is installed at one end of the L-shaped connecting pipe 518, a liquid blocking bin 524 is arranged on the inner side of the clamping frame 523, and a connecting conduit 531 connected to the hose 512 is installed on the top of the liquid blocking bin 524, A nozzle 529 is installed at the bottom of the liquid blocking tank 524, and a piston rod 522 extending to the outside of the L-shaped connecting tube 518 is inserted into the inside of the L-shaped connecting tube 518, and one end of the piston rod 522 is installed with an air blocking plug 532 located on the inside of the L-shaped connecting tube 518, and the end of the piston rod 522 away from the air blocking plug 532 is installed with a push rod 528 extending to the inside of the liquid blocking tank 524, and a return spring 521 connected to the L-shaped connecting tube 518 is provided on the piston rod 522, and the end of the push rod 528 away from the piston rod 522 is installed with a liquid blocking plug 530 located on the inside of the liquid blocking tank 524.

[0029] In this embodiment, when the L-shaped connecting tube 518 moves, the nozzle 529 is moved synchronously with the L-shaped connecting tube 518 through the positioning frame 523, so as to prevent the nozzle 529 from being too close to the surface of the foot line, causing the sprayed water flow to cause a large impact on the foot line. When the L-shaped jet chamber 520 is in a non-jet state, the liquid blocking plug 530 blocks the bottom of the connecting conduit 531, so as to prevent the water flow from passing through the liquid blocking chamber 524 and being sprayed by the nozzle 529. When the L-shaped connecting tube 518 sprays air flow, the increase in the amount of air inside the L-shaped connecting tube 518 will push the air blocking plug 532 to move toward the liquid blocking chamber 524, so that the air blocking plug 532 loses the top of the L-shaped jet chamber 520. When the air blocking plug 532 moves, the piston rod 522 and the push rod 528 drive the liquid blocking plug 530 to move, so as to move the liquid blocking plug 530 out from between the connecting conduit 531 and the nozzle 529. When the water pump injects water into the first annular bin 507 through the liquid spraying pipe 506, the water flow will pass through the hose 512, the connecting conduit 531, and the liquid blocking bin 524 and finally be sprayed out from the nozzle 529, so that the water flow is sprayed on the surface of the solidified extrusion line for further cooling, thereby realizing the orderly progress of air cooling and water cooling, and preventing the water flow from directly impacting the surface of the extrusion line and causing deformation of the extrusion line.

[0030] Please refer to Figure 5 The edge of the air blocking plug 532 is in contact with the inner wall of the L-shaped connecting tube 518.

[0031] In this embodiment: by setting this structure, the air blocking plug 532 can be pushed only when all L-shaped connecting pipes 518 are filled with air at the same time, so as to realize the simultaneous injection of multiple L-shaped injection chambers 520.

[0032] Please refer to Figure 2 , Figure 4 , Figure 8 Rotating sealing rings are provided at the connection between the first annular warehouse 507 and the second rotating warehouse 511 , and at the connection between the first rotating warehouse 508 and the second annular warehouse 516 .

[0033] In this embodiment: this structure is provided to improve the sealing performance of the connection between the first annular warehouse 507 and the second rotating warehouse 511, and the first rotating warehouse 508 and the second annular warehouse 516. At the same time, the second rotating warehouse 511 has rotation space relative to the first annular warehouse 507, and the first rotating warehouse 508 has rotation space relative to the second annular warehouse 516.

[0034] Please refer to Figure 2 , Figure 4 , Figure 8 The centers of the first annular bin 507, the second rotating bin 511, and the shifting chain 510 are coaxial.

[0035] In this embodiment: this structure is provided to prevent the first annular bin 507 from obstructing the leg line during the leg line extrusion process, and at the same time, the L-shaped connecting tube 518 drives the second rotating bin 511 to rotate through the hose 512 when rotating.

[0036] Please refer to Figure 2 The farthest distance from the side connecting frame 509 to the center of the first rotating warehouse 508 is greater than the farthest distance from the positioning slider 514 and the positioning block 515 to the center of the first rotating warehouse 508.

[0037] In this embodiment, this structure is provided to prevent the side connecting frame 509 from hindering the rotation of the pitch-adjusting screw rod 513 , thereby improving the smoothness of the rotation of the shifting link 510 .

[0038] In combination with the above-mentioned insulating PE leg wire extrusion production equipment, an insulating PE leg wire extrusion production method is provided, which specifically includes the following steps: S1: First, pour the plastic particles into the first feeding bin 2 and the second feeding bin 3, and then the plastic particles enter the screw extruder body 1 through the first feeding bin 2 and the second feeding bin 3. At this time, the material is heated and plasticized by the operation of the screw extruder body 1, and is pushed forward by the screw. The pitch-adjusting screw 513 is rotated according to the diameter of the extrusion end of the extruder head 4. When the pitch-adjusting screw 513 is rotated, the sleeve slider 514 can move along the pitch-adjusting screw 513, so that the shifting chain 510 drives the L-shaped connecting tube 518 to move through the oblique connecting frame 526, the U-shaped connecting frame 533, the guide plug rod 525, and the clamping plate 519, so that the L-shaped connecting tube 518 moves toward or away from the center of the first rotating bin 508, so as to adjust the distance from the L-shaped jetting bin 520 to the center of the first rotating bin 508, so that the L-shaped jetting bin 520 is flush with the edge of the extrusion end of the extruder head 4; S2: Start the motor 505. The operation of the motor 505 causes the transmission gear plate 504 to drive the transmission spur gear ring 502 to rotate, so that the transmission spur gear ring 502 drives the first rotating chamber 508 to rotate, so that the L-shaped jet chamber 520 can rotate along the center of the extruder head 4. When the external blower is in operation, the ejected airflow will be discharged through the second annular chamber 516, the first rotating chamber 508, the bellows telescopic tube 517, the L-shaped connecting tube 518, and the L-shaped jet chamber 520. At this time, when the extruder head 4 extrude the foot line, the airflow ejected from the L-shaped jet chamber 520 will blow around the foot line, so as to increase the fluidity of the air on the surface of the foot line. At the same time, the rotation of the L-shaped jet chamber 520 around the foot line realizes all-round cooling of the foot line surface, thereby improving the cooling efficiency of the foot line surface. S3: When the L-shaped connecting tube 518 moves, the nozzle 529 is moved synchronously with the L-shaped connecting tube 518 through the positioning frame 523, so as to prevent the nozzle 529 from being too close to the surface of the foot line, causing the sprayed water flow to cause a large impact on the foot line. When the L-shaped jet chamber 520 is in a non-jet state, the liquid blocking plug 530 blocks the bottom of the connecting conduit 531, so as to prevent the water flow from passing through the liquid blocking chamber 524 and being sprayed by the nozzle 529. When the L-shaped connecting tube 518 sprays air flow, the increase in the amount of air inside the L-shaped connecting tube 518 will push the air blocking plug 532 to move toward the liquid blocking chamber 524, so that the air blocking plug 532 loses the shielding of the top of the L-shaped jet chamber 520. At this time, the airflow will pass through the L-shaped connecting pipe 518 and finally be ejected from the L-shaped jet chamber 520. During the movement of the air blocking plug 532, the piston rod 522 and the push rod 528 will drive the liquid blocking plug 530 to move, so that the liquid blocking plug 530 is moved out from between the connecting conduit 531 and the nozzle 529. When the water pump injects water into the first annular chamber 507 through the liquid spraying pipe 506, the water will pass through the hose 512, the connecting conduit 531, and the liquid blocking chamber 524 and finally be ejected from the nozzle 529, so that the water flow is sprayed on the surface of the solidified extrusion line for further cooling, thereby realizing the orderly progress of air cooling and water cooling, and preventing the water flow from directly impacting the surface of the extrusion line and causing deformation of the extrusion line; S4: The cooled insulated PE leg wire is then reeled up using a reel.

[0039] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto.
