Description

Technical Field

[0001] This invention belongs to the field of cable protection pipe production technology, and particularly relates to a shaping device for extrusion production of cable protection pipes. Background Technology

[0002] Cables are the most important part of power transmission. In order to prevent damage to cables, cable protection pipes are pre-buried during the laying process to protect the cables. In the production process of cable protection pipes, in order to save resources and recycle, recycled plastics are melted and extruded to produce the protection pipes, which can also achieve the purpose of protecting the environment.

[0003] During the production of cable protection pipes, the extruded pipes are shaped by a sizing sleeve. A water outlet slit is set in the sizing sleeve to form a protective water film on the outer wall of the pipe. However, due to the narrowness of the slit, it is easily affected by scale, which prevents the water flowing out of the slit from forming an effective protective water film. This affects the forming effect of the pipe and often requires the machine to be stopped for cleaning, thus impacting production efficiency. Summary of the Invention

[0011] As a further description of the above technical solution: The guiding component further includes a turntable, which is installed on both sides of the first flap, and the turntable is rotatably connected to the through hole inside the mounting frame through a cylinder on one side. A torsion motor is installed on one side of the mounting frame and embedded inside the rotating shell. The torsion motor drives the turntable and the first flip plate to rotate, thereby adjusting the tilt angle of the first flip plate.

[0012] As a further description of the above technical solution: The guiding component further includes a connecting rod, one end of which is hinged to one end of the push rod, and the push rod is moved by the movement of the connecting rod. A fixed column is installed on the outer wall of the turntable, and one end of the connecting rod is rotatably sleeved on the outer wall of the fixed column.

[0015] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are: In this invention, by setting up a water film assembly, water can be sprayed out through a first or second water film ring during the process of the extruded protective tube entering the sizing sleeve. The water flow is then guided to the chamfered inlet of the sizing sleeve by a first or second guide plate, allowing the water film to smoothly enter between the protective tube and the sizing sleeve to protect the protective tube. If scale is generated, the first water film ring can be connected to a first cleaning chamber or the second water film ring to a second cleaning chamber, and the water film ring can be cleaned with cleaning fluid to ensure the quality of the water film. Furthermore, switching between the first and second water film rings can reduce the impact of machine downtime, thereby ensuring the smooth sizing of the protective tube.

[0016] In this invention, by setting a guiding component, the orientation of the first and second flaps can be changed so that the rotating shell can be in a state of outward water discharge during rotation. At the same time, since the rotating shell is connected to the sizing sleeve through the variable diameter sleeve and the sizing sleeve, a certain suction force can be generated at the gap between the variable diameter sleeve, the sizing sleeve and the protective tube. This facilitates the water flow from the gap on the outer wall of the sizing sleeve into the interior, thereby reducing the friction between the sizing sleeve and the formed protective tube, ensuring that the protective tube can be pulled outward smoothly, and guaranteeing the forming quality of the protective tube.

[0017] In this invention, by setting a rotating component, the water flow can be driven to enter from the side during the cooling process of the protective tube by the rotation of the rotating shell and discharged from the opening on the outer circumference of the rotating shell under the action of the guide plate, thereby completing the water flow circulation. Under the action of the guide plate, the water flow can be directed to the protective tube discharged from one end of the sizing sleeve to cool the protective tube, thereby improving the cooling efficiency and further improving the shaping efficiency of the protective tube.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] Please see Figures 1-10This invention provides a technical solution: a shaping device for extrusion production of cable protection pipes, including a support 1, a cooling box 3 at the top of the support 1, a sizing sleeve 6 inside the cooling box 3, and the sizing sleeve 6 being fixedly connected to one side of the cooling box 3 via a flange at one end; and further comprising: Water film assembly 5 includes a mounting sleeve 504 disposed on one side of the flange of sizing sleeve 6. A first water film ring 505 is provided inside the mounting sleeve 504. Water flowing out through the first water film ring 505 forms an isolation water film on the outer wall of the protective pipe. The rotating assembly 7 includes a rotating shell 704 disposed at the other end of the sizing sleeve 6. A partition 702 is provided on one side of the opening of the outer wall of the rotating shell 704, and multiple partitions 702 are arranged circumferentially, and the orientation of the partitions 702 is opposite to the rotation direction of the rotating shell 704. The guide component 8 includes a mounting frame 804 embedded in the side opening of the rotating shell 704, and multiple mounting frames 804 are arranged circumferentially. A first flap 801 is provided inside the mounting frame 804. The rotating shell 704 drives the mounting frame 804 and the first flap 801 to rotate, thereby using the first flap 801 to guide the water flow into the rotating shell 704. The cooling box 3 is equipped with a vacuum pump 4 at the top and a spray box 2 on one side. Multiple spray boxes 2 are arranged linearly. The water film assembly 5 also includes a second water film ring 510 and a water supply pipe 502. The second water film ring 510 is slidably disposed in the groove inside the mounting sleeve 504. The diameter of the second water film ring 510 is different from that of the first water film ring 505. The second water film ring 510 and the first water film ring 505 are staggered. A water supply pipe 502 is connected to one side of both the first water film ring 505 and the second water film ring 510. The water supply pipe 502 passes through the mounting sleeve 504 and is connected to an external water pump. like Figure 9 , Figure 10 As shown, the water film assembly 5 also includes: a first drainage plate 507 and a second drainage plate 509. The first diversion plate 507 is installed inside the mounting sleeve 504 and is located on one side of the first water film ring 505. The second diversion plate 509 is installed inside the mounting sleeve 504 and is located on one side of the second water film ring 510. The ends of the first diversion plate 507 and the second diversion plate 509 are both located at the inlet of the sizing sleeve 6. The water flowing out of the first water film ring 505 and the second water film ring 510 is guided by the first diversion plate 507 and the second diversion plate 509 to the inlet of the protective pipe and the sizing sleeve 6 to form a protective water film. The water film assembly 5 also includes: a first cleaning chamber 506 and a second cleaning chamber 508. The first cleaning chamber 506 is disposed inside the mounting sleeve 504 and is disposed opposite to the first water film ring 505. The first cleaning chamber 506 has a groove on one side corresponding to the first water film ring 505. The second cleaning chamber 508 is disposed inside the mounting sleeve 504 and is disposed opposite to the second water film ring 510. The second cleaning chamber 508 has a groove on one side corresponding to the second water film ring 510. The water film assembly 5 also includes: a cleaning pipe 503 and an electric actuator 501. A cleaning pipe 503 is disposed on one side of the first cleaning chamber 506 and the second cleaning chamber 508, and the other end of the cleaning pipe 503 passes through the mounting sleeve 504. The first water film ring 505 and the second water film ring 510 are respectively moved into the grooves on one side of the first cleaning chamber 506 and the second cleaning chamber 508. The cleaning fluid is delivered into the first cleaning chamber 506 and the second cleaning chamber 508 through the cleaning pipe 503. An electric push rod 501 is installed on the outer wall of the mounting sleeve 504, and multiple electric push rods 501 are provided. One side of the first water film ring 505 and the second water film ring 510 are connected to the telescopic end of the electric push rod 501. The electric push rod 501 drives the first water film ring 505 and the second water film ring 510 to move and adjust the position of the first water film ring 505 and the second water film ring 510.

[0031] Specifically: During the production process of the cable protection pipe, as the extruder extrudes the raw material and gradually feeds it into the sizing sleeve 6, water can be sprayed out through the annular gap of the first water film ring 505 or the second water film ring 510. At the same time, under the guidance of the first guide plate 507 and the second guide plate 509, the water can flow to the chamfered inlet of the sizing sleeve 6 and between the protection pipe in the sizing process. And because the cooling box 3 is under negative pressure under the action of the vacuum pump 4, the water can smoothly enter the chamfered inlet of the sizing sleeve 6, thereby protecting the protection pipe through the water film. Furthermore, with prolonged use, if the annular gap of the first water film ring 505 or the second water film ring 510 becomes clogged due to scale, the first water film ring 505 or the second water film ring 510 can be moved by the electric push rod 501, so that the first water film ring 505 or the second water film ring 510 enters the groove on one side of the corresponding first cleaning chamber 506 or second cleaning chamber 508. Furthermore, since the connection between the first water film ring 505 and the first cleaning chamber 506 and the second water film ring 510 and the second cleaning chamber 508 is provided with a corresponding sealing structure, cleaning fluid can be introduced into the first cleaning chamber 506 or the second cleaning chamber 508 through the cleaning pipe 503. In this way, the first water film ring 505 or the second water film ring 510 can be cleaned by the cleaning fluid, so as to reduce the impact of scale on the first water film ring 505 or the second water film ring 510 and ensure the smooth formation of the water film.

[0032] like Figure 5 , Figure 6 As shown, the guide assembly 8 also includes: a second flap 803, a gear 809, and a push rod 808. The second flap 803 is rotatably mounted on both ends of the mounting frame 804 via a rotating shaft. The second flap 803 and the first flap 801 are provided with matching grid holes. When the second flap 803 is flipped, its grid holes are intersected with the grid holes of the first flap 801. Water is guided into the rotating shell 704 through the second flap 803. The gear 809 is installed at both ends of the second flap 803. The push rod 808 is slidably disposed in the groove inside the mounting frame 804. One end of the push rod 808 is provided with teeth corresponding to the gear 809. By moving the push rod 808, the teeth drive the gear 809 to rotate, thereby adjusting the tilt angle of the second flap 803. The guide assembly 8 also includes: a turntable 805 and a torsion motor 802. Turntable 805 is installed on both sides of the first flap 801, and turntable 805 is rotatably connected to the through hole inside the mounting frame 804 through a cylinder on one side. Torque motor 802 is installed on one side of the mounting frame 804, and torsion motor 802 is embedded inside the rotating shell 704. Torque motor 802 drives turntable 805 and the first flap 801 to rotate, so as to adjust the tilt angle of the first flap 801. The guide assembly 8 also includes: a link 807 and a fixed post 806. One end of the connecting rod 807 is hinged to one end of the push rod 808. The movement of the connecting rod 807 drives the push rod 808 to move. The fixed column 806 is installed on the outer wall of the turntable 805, and one end of the connecting rod 807 is rotatably sleeved on the outer wall of the fixed column 806. The turntable 805 drives the fixed column 806 to move, so that the connecting rod 807 drives the push rod 808 to move.

[0033] Specifically: As the rotating shell 704 rotates, since the first flap 801 is in an inclined state and the inclined surface faces the direction of rotation, the rotating shell 704 can drive the mounting frame 804 and the first flap 801 to rotate during the rotation process. In this way, under the action of the first flap 801, water can enter the interior of the rotating shell 704 and be discharged from the through hole on the outer circumference of the rotating shell 704, thereby cooling the protective tube that has just been discharged from the end of the sizing sleeve 6. At the same time, the water flow on the inner wall of the rotating shell 704 can be guided by the second flap 803 located inside the rotating shell 704, reducing its scouring of the first flap 801, so that the external water flow can enter smoothly. Furthermore, if the water film between the protective tube and the sizing sleeve 6 disappears, leading to increased friction, the first flap 801 can be rotated by the torsion motor 802 so that the back of the first flap 801 is in the same direction of rotation. This allows water to flow outward along the first flap 801. Since the rotating shell 704 is connected to the sizing sleeve 6 through the variable diameter sleeve 706, and the water inside the rotating shell 704 is discharged outward, a certain suction force is generated at the gap between the sizing sleeve 6, the variable diameter sleeve 706 and the protective tube. This suction force draws water from inside the cooling tank 3 inward through the gap in the sizing sleeve 6, allowing water to enter the gap between the sizing sleeve 6 and the protective tube, thereby reducing friction between the sizing sleeve 6 and the protective tube. Furthermore, during the rotation of the first flap 801, the turntable 805 is driven to rotate, thereby driving the connecting rod 807 to move via the fixed column 806. The connecting rod 807 then drives the push rod 808 to move, and the teeth on one side of the push rod 808 drive the gear 809 to rotate, thereby causing the second flap 803 to flip and change its angle.

[0034] like Figure 7 , Figure 8 As shown, the rotating assembly 7 also includes: a spoiler 701, a gear ring 703, and a drive module 705. A baffle 701 is installed at one end of a baffle 702 and corresponds to the baffle 702. As the rotating shell 704 rotates, the baffle 701 is used to adjust the water flow on one side of the baffle 702. A toothed ring 703 is installed on the outer wall of the rotating shell 704. A drive module 705 is located on one side of the cooling box 3 and the drive end of the drive module 705 is connected to the toothed ring 703. The drive module 705 drives the toothed ring 703 to rotate, thereby driving the rotating shell 704 to rotate. The rotating assembly 7 also includes: a guide vane 707 and a variable diameter sleeve 706. The guide plate 707 is installed on one side of the inner wall of the rotating shell 704, and one end of the guide plate 707 corresponds to the first flap 801, and the other end of the guide plate 707 corresponds to the partition 702. The guide plate 707 guides the water flow inside the rotating shell 704. The variable diameter sleeve 706 is rotatably installed on one side of the rotating shell 704, and the other end of the variable diameter sleeve 706 is fixedly connected to the fixed diameter sleeve 6. In another embodiment, the drive module 705 consists of a motor and a transmission gear, which is well known in the technical field, so it is not described in detail here. An electromagnetic slip ring can be provided on one side of the rotating shell 704 to supply power to the torsion motor 802.

[0035] Specifically: During the cooling process of the protective tube, the drive module 705 can drive the gear ring 703 to rotate, thereby driving the rotating shell 704 to rotate. At the same time, during the rotation of the rotating shell 704, water can be guided into the interior of the rotating shell 704 through the first flap 801 on the side of the rotating shell 704, and discharged through the opening on the circumferential side of the rotating shell 704 to complete the circulation of water. Furthermore, the water flow outside the rotating shell 704 can be guided by the baffle 702, and the water flow at the opening of the rotating shell 704 can be accelerated by the baffle 701, thereby speeding up the water flow to be discharged from the inside of the rotating shell 704. Furthermore, as water flows into the interior of the rotating shell 704 through the opening on one side, since one end of the guide plate 707 corresponds to the first flap 801 and the other end of the guide plate 707 corresponds to the circumferential opening of the rotating shell 704, the water flowing in from the side can approach the outside of the protective tube under the action of the guide plate 707, thereby accelerating the cooling rate of the protective tube. At the same time, it can prevent the water flowing in from the side opening of the rotating shell 704 from being directly discharged from the adjacent circumferential opening.

[0036] Working principle: As the protective tube is extruded from the extruder and enters the sizing sleeve 6, water can be discharged through the first water film ring 505 or the second water film ring 510. Under the action of the first guide plate 507 and the second guide plate 509, the water flows into the chamfer of the inlet of the sizing sleeve 6, so that the water flow forms a water film to protect the protective tube. If scale is generated, the first water film ring 505 can be pushed to connect with the first cleaning chamber 506 or the second water film ring 510 to the second cleaning chamber 508 by the electric push rod 501, so that the first water film ring 505 or the second water film ring 510 can be cleaned by the cleaning fluid. Furthermore, the rotating shell 704 can be driven to rotate by the drive module 705, and then the first flap 801 and the second flap 803 can be used to guide the water flow from the opening on the side of the rotating shell 704 into the interior of the rotating shell 704, and the water flow can be guided by the guide plate 707 so that the water flow can cool the protective pipe that has just been discharged from one end of the sizing sleeve 6. Furthermore, the first flap 801 can be flipped by the torsion motor 802, which in turn drives the turntable 805 to rotate. Under the action of the fixed column 806, the connecting rod 807 and the push rod 808 are rotated, which in turn causes the second flap 803 to flip. This makes the openings on the side and circumference of the rotating shell 704 discharge water outward. This creates suction at the gap between the variable diameter sleeve 706 and the fixed diameter sleeve 6 and the protective pipe, ensuring that water can enter the interior of the fixed diameter sleeve 6 through the gaps in the outer wall of the fixed diameter sleeve 6.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
