Description

Technical Field

[0001] The present invention relates to the technical field of corrugated pipes, and specifically to an HDPE multi-hole reinforced winding corrugated pipe. Background Art

[0002] HDPE, that is, polyethylene material, is a commonly used material in modern pipe structures. In modern pipe structures, in order to improve the structural strength of the pipe, in addition to using high-strength materials, reinforcing ribs, that is, corrugated pipes, are often provided on the pipe. The radial bearing capacity of the pipe is strengthened by densely arranged reinforcing ribs.

[0003] At present, most corrugated pipes are processed by winding and reinforcing. Different extruders are used to extrude the base pipe and the winding pipe respectively. In the past, the winding pipe was mainly a solid structure. Although this kind of reinforcing rib is simple in structure and convenient for production, its structural weight is large and its flexibility is poor. Therefore, at present, multi-stage punching operations are carried out on the reinforcing ribs of the corrugated pipe to reduce the structural weight of the rib strips and obtain higher flexibility at the same time.

[0004] However, at present, the winding corrugated pipes mainly adopt a spiral winding layout, and the reinforcing ribs are combined with the base pipe by means of bonding and hot melt bonding. However, since both the base pipe and the winding reinforcing ribs are extruded separately and then compounded, the bonding part between the base pipe and the reinforcing ribs is not fully bonded, resulting in cracking problems during the application of the corrugated pipe. In view of this, in-depth research on the above problems has led to the generation of this case. Summary of the Invention

Therefore, the production equipment adopts a gradient cooling system (rapid cooling in the core + slow heating on the surface) to make the surface of the pipe in a molten state of the plate, and it is easier for the reinforcing rib to combine with the surface of the base pipe during spiral winding. The porous rib column design of the reinforcing rib reduces the weight while ensuring that the ring stiffness reaches SN16, solving the core defect of poor bonding in traditional step-by-step processing.

[0027] 1. Through the coordinated work of the main pipe extruder and the reinforcing rib extruder, the synchronous extrusion and hot melt compounding of the base pipe and the reinforcing rib are realized, eliminating the interface bonding defect of traditional step-by-step processing. The reinforcing rib is formed by rapid cooling, and the base pipe is matched with a cooling tube core (rapid cooling in the core) and an external heating cover (slow heating on the surface), so that the base pipe is quickly shaped while maintaining the molten state of the bonding surface, which is convenient for compounding with the reinforcing rib;

[0028] 2. When the reinforcing rib enters the stage of composite winding, the attitude of the reinforcing rib is corrected by using the guiding component, and the guiding roller press provides a downward pressure to make the reinforcing rib more stably compounded on the base pipe;

[0029] 3. For the HDPE winding corrugated pipe produced by the above equipment, the reinforcing rib adopts a double positioning design of a dovetail-shaped fusion groove and a guiding wire, so that the bonding strength between the base pipe and the reinforcing rib is increased by at least 3 MPa, and the anti-cracking performance is improved.

Detailed implementation manners

[0041] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention.

Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0042] Please refer to Figures 1-10, the present invention provides an implementation: At present, the winding corrugated pipe mainly adopts spiral winding for layout, and the reinforcing rib 2 is combined with the base pipe 1 by means of bonding and hot melt combination. However, in this processing method, since the base pipe 1 and the winding reinforcing rib are separately extruded and then compounded, the bonding part between the base pipe 1 and the reinforcing rib is not fully bonded, resulting in the problem of cracking of the corrugated pipe during application.

[0043] Example 1: According to the attached drawings of the specification Figures 9-10 As can be seen, in view of the above problems, the present application discloses an HDPE porous reinforced winding corrugated pipe, including a base pipe 1, the base pipe 1 is a pipe body made of high-density polyethylene material, a reinforcing rib 2 is arranged outside the base pipe 1, the cross section of the reinforcing rib 2 is a triangular structure, and the longitudinal bearing capacity of the base pipe 1 is improved by the compounding of the reinforcing rib 2 and the base pipe 1. A rib column 21 is arranged in the middle of the reinforcing rib 2, the rib column 21 divides the reinforcing rib 2 into two chambers, and a plurality of through holes 22 are arranged on the rib column 21. The structural weight of the reinforcing rib 2 can be effectively reduced through the two cavities, and the reinforcing rib 2 is spirally arranged around the base pipe 1, effectively improving the mechanical structural characteristics of the reinforcing rib 2, and the rib column 21 is perpendicular to the surface of the base pipe 1, and the cross section of the rib column 21 is a rectangular structure, which is convenient for production;

[0044] A plurality of parallel arranged fusion grooves 23 are arranged on the bottom surface of the reinforcing rib 2, and a plurality of fusion strips 11 are arranged on the outer wall of the base pipe 1 corresponding to the fusion grooves 23. The plurality of fusion strips 11 are assembled in the plurality of fusion grooves 23, and the cross section of any one of the fusion grooves 23 is a dovetail structure, and the cross section of the fusion strip 11 matches the cross section of the fusion groove 23. Through the interactive structure design of the plurality of fusion strips 11 and the plurality of fusion grooves, the base pipe 1 and the reinforcing rib 2 are interlocked, improving the bonding consistency between the reinforcing rib 2 and the base pipe 1. The fusion strip 11 is integrally formed with the base pipe 1, and the fusion strip 11 and the fusion groove 23 are in one-to-one correspondence and are connected by hot melt. This is because in the processing process, first, the forming die of the base pipe 1 of the reinforced winding corrugated pipe is improved to accurately control the surface temperature of the base pipe 1 so that it is in a molten state of the plate, and then the reinforcing rib 2 is pressed on the base pipe 1 to form a composite interlocking structure;

[0045] Furthermore, a plurality of guide lines 24 are arranged between the plurality of fusion grooves 23, the plurality of fusion grooves 23 and the plurality of guide lines 24 are evenly and alternately arranged, a plurality of guide grooves 12 are arranged on the surface of the base pipe 1 corresponding to the plurality of guide lines 24, the plurality of guide lines 24 are inserted into the plurality of guide grooves 12, and the guide lines 24 and the guide grooves 12 are in one-to-one correspondence and are connected by hot melt. Through the cooperation of the guide lines 24 and the guide grooves 12, the function of the interlocking connection is further improved.

[0046] Embodiment 2: In order to manufacture the above-mentioned HDPE porous reinforced winding bellows, the present application also discloses an HDPE porous reinforced winding bellows processing device, including a main pipe extruder 3 for extruding a base pipe 1, and a reinforcing rib extruder 4 for extruding reinforcing ribs 2. The feeding end of the main pipe extruder 3 is connected to a continuous winding mechanism 5. A reinforcing rib extruder 4 is arranged on one side of the continuous winding mechanism 5. The continuous winding mechanism 5 is responsible for compounding the base pipe 1 and the reinforcing ribs 2. A continuous feeder should be arranged at the feeding end of the continuous winding mechanism 5 to push the pipe for feeding;

[0047] Furthermore, a cooling mechanism 6 is arranged on one side of the continuous winding mechanism 5 corresponding to the reinforcing rib extruder 4. A traction frame 7 is arranged on one side of the cooling mechanism 6. A pair of traction rollers 71 on the traction frame 7 are used to traction the reinforcing ribs. A pair of traction rollers 71 are driven by a pair of traction motors 72. A pair of traction rollers are driven by a pair of traction motors 72 to traction the cooled reinforcing ribs 2 to ensure the stable extrusion of the reinforcing ribs 2;

[0048] Furthermore, according to the appended drawings of the specification Figures 1-3 As can be seen, the above-mentioned continuous winding mechanism 5 includes a conveyor housing 51 arranged at the end of the main pipe extruder 3. The conveyor housing 51 is a frame with a rectangular structure. An inlet 512 is arranged at the connection between the conveyor housing 51 and the main pipe extruder 3 for the base pipe 1 to enter the continuous winding mechanism 5. The diameter of the conveyor housing 51 is larger than the diameter of the inlet 512. The conveyor housing 51 serves as the main support of the continuous winding mechanism 5. An inlet groove 511 is arranged on one side of the conveyor housing 51 corresponding to the continuous reinforcing rib extruder 4. The reinforcing ribs 2 extruded by the reinforcing rib extruder 4 pass through the inlet groove 511. The size of the inlet groove 511 is slightly larger than the size of the reinforcing ribs 2. A guiding component 52 is arranged inside the inlet groove 511 to limit the position where the reinforcing ribs 2 enter. A guiding roller press 53 is arranged below the guiding component 52 to press the bonding position of the reinforcing ribs 2 and the base pipe 1, making the bonding between the reinforcing ribs 2 and the base pipe 1 more stable;

[0049] Furthermore, according to the appended drawings of the specification Figures 1-3 As can be seen, the above-mentioned continuous winding mechanism 5 further includes a cooling tube core 54 connected to the main pipe extruder 3. The cooling tube core 54 is built into the die of the main pipe extruder 3 and can rotate synchronously with the main pipe extruder 3. The cooling tube core 54 cools the inner wall of the base pipe 1. A circulating cooler 55 is arranged on one side of the cooling tube core 54. The circulating cooler 55 injects liquid cooling water into the cooling tube core 54 through a cooling conduction component 56. A circulating path is formed through the circulating cooler 55, the cooling tube core 54 and the cooling conduction component 56 to cool the base pipe 1 by circulating cold water;

[0050] Furthermore, according to the appended drawings of the specificationFigures 1-4 It can be seen that the above-mentioned continuous winding mechanism 5 further includes an external heating cover 57. The external heating cover 57 is coaxially arranged outside the cooling tube core 54. A number of thermocouple heaters are arranged on the external heating cover 57. The external heating cover 57 is arranged on the side where the base tube 1 is fed. The surface temperature of the base tube 1 is precisely controlled and maintained by the heating cover, so that the base tube 1 cannot be immediately cooled and formed, but remains in a semi-molten state, enabling the base tube 1 and the reinforcing rib 2 to be integrally formed.

[0051] Furthermore, a main pipe extrusion die 31 is movably connected to the end of the main pipe extruder 3. The main pipe extrusion die 31 is connected to the side wall of the cooling tube core 54. The main pipe extrusion die 31 is controlled to rotate by a driving motor 32. The driving motor 32 drives the main pipe extrusion die 31 to rotate continuously through a reduction gear structure. The layout of the main pipe extruder 3 and the main pipe extrusion die 31 is an L-shaped structure. The main pipe extrusion die 31 is inserted into the feed port 512. The rotation of the main pipe extrusion die 31 is stabilized by using the feed port 512 as a bearing. At the same time, the distance between the extruded base tube 1 and the reinforcing rib 2 is shortened. Furthermore, the main pipe extrusion die 31 is a double-layer structure. The channel for extruding the base tube 1 is between the inner and outer layers of the main pipe extrusion die 31. The inner layer of the main pipe extrusion die 31 is connected to the cooling tube core 54, and the base tube 1 is directly cooled by the cooling effect provided by the cooling tube core 54.

[0052] According to the description in the attached Figures 1-5 It can be seen that the above-mentioned cooling mechanism 6 includes a cooling tank 61. The cooling tank 61 is connected to the side of the conveyor housing 51. The cooling tank 61 is used to recover cooling water. The end of the cooling tank 61 is connected to the reinforcing rib extruder 4. A number of supporting rollers 62 are arranged on the cooling tank 61. The reinforcing rib 2 passes through a number of supporting rollers 62. A spray box 63 is arranged on the cooling tank 61. A sprayer 64 is arranged on the top surface of the spray box 63. A drain pipe 65 is arranged on the cooling tank 61;

[0053] In the specific implementation process, the cooling tank 61 serves as the space for collecting and circulating the cooling water. The spray box 63 on the cooling tank 61 serves as the space through which the reinforcing rib 2 passes. The supporting rollers 62 on the cooling tank 61 are used to support the reinforcing rib 2. When the reinforcing rib 2 passes through, the sprayer 64 on the spray box 63 sprays cooling water downward, and the cooling water is used to cool the reinforcing rib, enabling the reinforcing rib to be quickly formed. The cooling water recovered by the cooling tank 61 is recycled through the drain pipe 65.

[0054] According to the description in the attached Figures 1-6It can be seen that the above-mentioned guiding component 52 includes three screw rod adjusters 521. The three screw rod adjusters 521 are arranged in a circular array outside the inlet groove 511. Three limiting rollers 522 are respectively arranged at the end parts of the three screw rod adjusters 521. The three screw rod adjusters 521 can adjust the linear movement of the three limiting rollers 522. Since the cross-sectional structure of the reinforcing rib 2 is similar to a triangle, guiding devices are arranged in three directions to limit the angle of the reinforcing rib 2 entering the continuous winding mechanism 5. Specifically, the screw rod adjuster 521 is used to adjust the limiting roller 522 so that the limiting roller 522 contacts the surface of the reinforcing rib 2, realizing the limiting effect on the reinforcing rib 2.

[0055] According to the attached drawings of the specification Figures 1-6 It can be seen that the above-mentioned guiding roller press 53 includes a indexing adjustment base 531. The indexing adjustment base 531 is arranged on the inner top surface of the conveyor housing 51. A lifting telescopic device 532 is connected to the bottom of the indexing adjustment base 531. The telescopic end of the lifting telescopic device 532 is connected with a guiding roller 533. The guiding roller 533 presses down on the reinforcing rib 2 to combine the reinforcing rib 2 with the base pipe 1.

[0056] In the specific implementation process, the reinforcing rib 2 entering through the guiding component 52 needs to be compounded on the base pipe 1. In order to improve the compounding effect, a guiding roller press 53 is arranged on the top surface of the conveyor housing 51. The guiding roller press 53 takes the indexing adjustment base 531 as the installation basis. The indexing adjustment base 531 can be used to adjust the lifting telescopic device 532 to drive the guiding roller 533 to rotate horizontally, thereby adjusting the angle of the guiding roller 533. The bottom of the guiding roller 533 matches the reinforcing rib. A pre-pressure is set through the lifting telescopic device 532 so that the reinforcing rib 2 passing through the guiding roller 533 can be quickly combined with the base pipe 1.

[0057] According to the attached drawings of the specification Figures 1-8 It can be seen that the above-mentioned circulating cooler 55 includes a cooling storage tank 551. A cooling medium is stored in the cooling storage tank 551. A circulating pump 552 is connected to one side of the cooling storage tank 551. A water supply pipe 553 and a water return pipe 554 are respectively arranged on the cooling storage tank 551 and the circulating pump 552. The cooling storage tank 551 is used as a circulating container to store the cooling medium inside. A cooler is also arranged on the cooling storage tank 551 to circulate and cool the cooling medium. The circulating pump 552 is used to send the cooling medium from the cooling storage tank 551 through the water supply pipe 553 to the cooling tube core 54, and then the water is returned to the cooling storage tank 551 through the water return pipe 554, thus completing the cycle as the cooling power.

[0058] According to the attached drawings of the specification Figures 1-8It can be seen that the above cooling and conduction assembly 56 includes a cooling control pipe 561. One side of the cooling pipe core 54 is connected to the cooling control pipe 561. The cooling control pipe 561 penetrates through the main pipe extrusion die 31. A cooling water inlet joint 562 is arranged at the shaft end of the cooling control pipe 561. The cooling water inlet joint 562 extends into the cooling pipe core 54 through a cooling water inlet pipe 563. The cooling pipe core 54 is of an inner cavity structure, and a plurality of cooling nozzles are annularly arranged on the side connected to the inner wall of the main pipe extrusion die 31. The cooling water inlet joint 562 is movably connected to the water supply pipe 553. A return water ring sleeve 564 is sleeved outside the end of the cooling control pipe 561. A return water groove 565 is radially opened at the tail end of the cooling control pipe 561;

[0059] In the specific implementation process, the cooling and conduction assembly 56 cools the pipe wall in a two-way coaxial circulation manner. The cooling and conduction assembly 56 takes the cooling control pipe 561 as the main body. The cooling control pipe 561 is communicated with the inner core cavity of the main pipe extrusion die 31. The coaxial cooling water inlet pipe 563 in the cooling control pipe 561 is connected to the cooling pipe core 54. The cooling water given by the water supply pipe 553 enters the cooling pipe core 54, forms a split flow at the tail end of the cooling pipe core 54, and the cooling water is sprayed out by a plurality of cooling nozzles. Since the position is closer to the tail end of the main pipe extrusion die 31 after the cooling water is sprayed out, the base pipe 1 to be extruded is first cooled to ensure smooth extrusion. Then, it flows back to the outside through the inner core of the main pipe extrusion die 31, so as to slowly cool the material on the side close to the extruder of the base pipe 1. Due to the annular cavity between the cooling control pipe 561 and the cooling water inlet pipe 563 and the cavity between the cooling pipe core 54 and the main pipe extrusion die 31, the cooling water flows back from the cooling control pipe 561, then flows into the return water ring sleeve 564 through the return water groove 565. The return water ring sleeve 564 is connected to the return water pipe 554, and the water is circulated to the cooling storage tank 551 through the return water pipe 554 to complete the cooling cycle. In this way, on the one hand, the cooling effect on the base pipe 1 is ensured and the closer to the discharge end, the better the cooling effect. At the same time, by using the double-layer annular space, the extruded material will not directly contact the coolant, avoiding pollution.
