Description

[0002] Hollow wall winding pipe is a structural wall pipe made by hot winding molding process. It has strong flexibility, smooth inner wall, low flow resistance, wear resistance and corrosion resistance. It is suitable for municipal drainage, sewage, sports field and square engineering drainage and electrical telecommunications engineering. High-density polyethylene (HDPE) has the advantages of light weight, low toxicity, high electrical insulation, chemical resistance and easy processing.

A steel hoop is arranged in the cavity between the inner and outer walls, and the outer wall trapezoidal bottom groove is connected to the inner wall as a whole. The large-caliber double-wall corrugated water pipe is provided with a steel hoop in the cavity between the inner and outer walls, which improves the strength of the water pipe, and compared with the large-caliber steel-plastic drainage pipe commonly used in the prior art, it has the characteristics of light overall weight, low cost, easy installation and use, and low production cost.

[0035] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the relevant drawings. The preferred embodiments of the present invention are given in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thoroughly understood.

[0037] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0038] The present invention provides a high-density polyethylene steel wire reinforced hollow wall winding pipe 10, which comprises a pipe wall 11 which is infinitely extended in the axial direction by spiral winding.

[0039] like Figure 1 and Figure 2 As shown, the tube wall 11 is formed by spirally winding the base tube 100, and a connecting layer 12 is formed between adjacent side walls of the base tube 100, and a steel wire 13 is arranged in the connecting layer 12. Figure 3 As shown, the cross section of the base tube 100 is a hollow rectangular structure, a receiving groove 101 is provided on one side of the base tube 100 , and a convex ridge 102 adapted to the receiving groove 101 is provided on the other side of the base tube 100 .

[0040] The connection layer 12 and the base tube 100 have the same height in the same cross section, that is, the inner and outer walls of the tube wall 11 are both smooth and flat.

[0041] It should be noted that the steel wire 13 of the high-density polyethylene steel wire reinforced hollow wall winding tube 10 of the present invention is arranged in the connecting layer 12, while in the prior art, the steel wire 13 is usually arranged in the cavity of the base tube 100, and the position of the steel wire 13 in the cavity of the base tube 100 is not easy to be fixed, resulting in more or less deviations in the position of the steel wire 13 in each section of the base tube 100, and the degree of standardization is not high, so that the overall strength of the tube wall 11 is limited. Compared with the prior art, the steel wire 13 of the present invention is wrapped in the connecting layer 12, and its position is fixed and not easy to be misplaced, so that the overall strength of the tube wall 11 can be significantly improved.

[0042] In addition, it is worth emphasizing that the base tube 100 is provided with a receiving groove 101 and a convex ridge 102. During the production process, when the base tube 100 is wound, the steel wire 13 will be embedded in the connecting layer 12, and the steel wire 13 will be blocked by the convex ridge 102 and the receiving groove 101, so that the embedding depth of the steel wire 13 can be ensured to be consistent, which can achieve standardization on the one hand, and reduce the difficulty of production on the other hand, so that the steel wire 13 can be accurately embedded in the connecting layer 12.

[0043] Furthermore, in order to realize industrialized and standardized production of the above-mentioned high-density polyethylene steel wire reinforced hollow wall winding pipe 10, the present invention also provides a hollow wall winding pipe production equipment 20, such as Figure 4 As shown, it mainly includes: an extrusion molding device 200, a cooling device 300, a winding device 400 and a steel wire unwinding device 500. The cooling device 300 is arranged between the extrusion molding device 200 and the winding device 400. The extrusion molding device 200 is used to produce a base tube 100. The produced base tube 100 will pass through the cooling device 300 and the winding device 400 in sequence. The steel wire unwinding device 500 provides the steel wire 13 for the winding device 400.

[0044] Among them, Figure 5 and Figure 6 As shown, the winding device 400 includes: a machine base 410, a winding disc 420, a hot extrusion assembly 430 and a trimming assembly 440. The winding disc 420 is rotatably arranged on the machine base 410, the hot extrusion assembly 430 is arranged on the machine base 410 and above the winding disc 420, and the trimming assembly 440 is used to cooperate with the winding disc 420 to wind the base tube 100 to form a high-density polyethylene steel wire reinforced hollow wall winding tube 10.

[0045] like Figure 6 As shown, a plurality of reels 421 arranged in a circular array are provided on the winding disk 420, and the substrate tube 100 is wound on the reels 421. The hot extrusion assembly 430 includes a discharge nozzle 431 and a guide frame 432, wherein the discharge nozzle 431 is located above the reel 421, and the guide frame 432 is disposed on one side of the discharge nozzle 431, and the steel wire 13 passes through the guide frame 432 and extends to the substrate tube 100 on the winding disk 420.

[0046] In this embodiment, if Figure 6 As shown, the trimming assembly 440 includes an extrusion roller 441 and a smoothing roller 442. The extrusion roller 441 is arranged at the end of the reel 421 through a bracket. The extrusion roller 441 is used to extrude the base tube 100 toward the free end of the reel 421, and the smoothing roller 442 is pressed against the tube wall 11 of the hollow wall winding tube 10.

[0047] like Figure 6 and Figure 7As shown, preferably, the winding device 400 also includes a cooling component 450 and a brace 460.

[0048] like Figure 6 As shown, the cooling assembly 450 includes: a cooling box 451, a cooling nozzle 452 and a circulation pump (not shown), the cooling box 451 is arranged below the winding drum 420, the cooling box 451 contains a cooling liquid, the cooling nozzle 452 and the circulation pump are arranged on the cooling box 451, and the cooling nozzle 452 is directed toward the hollow wall winding tube 10 on the winding drum 420. Figure 7 As shown, the orthopedic frame 460 is disposed at the front end of the winding drum 420 , and a shaping groove 461 for supporting the hollow wall winding tube 10 is provided on the orthopedic frame 460 .

[0049] Preferably, Figure 4 As shown, the extrusion molding device 200 includes: a hopper 210, a driving component 220 and an extruder barrel 230. The hopper 210 is connected to the extruder barrel 230, and a screw (not shown) is arranged in the extruder barrel 230, which is driven and connected to the driving component 220, and a heating sleeve 231 is arranged outside the extruder barrel 230.

[0050] like Figure 4 As shown, the wire unwinding device 500 includes an unwinding frame 510 and a guide wheel 520. The unwinding frame 510 is used to place the wire coil. The guide wheel 520 is installed on the winding device 400. After starting from the unwinding frame 510, the steel wire 13 passes around the guide wheel 520 and the guide frame 432 in sequence.

[0051] Next, in combination with the above structure, the working principle of the hollow wall winding pipe production equipment 20 of the present invention is explained:

[0052] First, the base tube 100 is produced by the extrusion molding device 200. Specifically, the raw material enters the extruder barrel 230 through the feed hopper 210, the heating sleeve 231 heats the extruder barrel 230 and the raw material therein, and then the driving component 220 drives the screw to rotate and extrude the molten raw material to form the base tube 100;

[0053] The newly produced base tube 100 is initially cooled and shaped by the cooling device 300, and then enters the winding device 400;

[0054] When entering the winding device 400, the substrate tube 100 is wound on the reel 421 of the winding disk 420. As the winding disk 420 and the plurality of reels 421 rotate, the substrate tube 100 is wound spirally on the reel 421 (e.g., Figure 7 and Figure 8As shown in FIG. 1 , each turn of the base tube 100 is a section, and there is a gap between two adjacent sections of the base tube 100. One of the functions of the winding device 400 is to fill the gap, form a connecting layer 12, and embed the steel wire 13 into the connecting layer 12;

[0055] Specifically, during winding, the base tube 100 that has just contacted the reel 421 will rotate together with it, and the base tube 100 at this time will pass under the discharge nozzle 431; the discharge nozzle 431 sprays the raw material of the connecting layer 12 on the side wall of the base tube 100. Subsequently, the base tube 100 contacts the extrusion roller 441 of the trimming assembly 440, and the extrusion roller 441 will push the base tube 100 forward, so that the base tube 100 contacts and squeezes the previous base tube 100. At this time, the raw material of the connecting layer 12 is squeezed and fills the gap between the two base tubes 100, so that the next base tube 100 is bonded to the previous base tube 100. At the same time, during winding, the steel wire 13 starts from the unwinding frame 510, and successively bypasses the guide wheel 520 and the guide frame 432, and finally extends to the gap between the two base tubes 100. During the filling process of the connecting layer 12 raw material, the steel wire 13 is embedded into the gap together with the raw material, and the steel wire 13 in the unwinding rack 510 is continuously unwound under the clamping of the two sections of the base tube 100. During the continuous winding process of the base tube 100, the steel wire 13 is pulled by the two sections of the base tube 100 and approaches the axial direction. Coincidentally, the steel wire 13 will be blocked by the convex rib 102 and will not sink deeper, thereby ensuring the embedding depth of the steel wire 13; it should also be noted that the accommodating groove 101 and the convex rib 102 cooperate with each other, and the convex rib 102 will be adaptively partially accommodated in the accommodating groove 101, preventing the convex rib 102 from directly holding on to the side wall of the plane and causing the two sections of the base tube 100 to be unevenly bonded;

[0056] With the filling of the connecting layer 12 raw material and the pushing of the extrusion roller 441, the excess raw material in the gap will overflow to the inner and outer sides of the tube wall 11. The rotating reel 421 can smooth the overflowing raw material on the inner side of the tube wall 11, and the smoothing roller 442 is pressed on the outer side of the tube wall 11, which can smooth the overflowing raw material on the outer side, so that the inner and outer walls of the hollow wall winding tube 10 will become smooth and flat;

[0057] As the base tube 100 is continuously wound, a hollow-walled wound tube 10 is gradually formed on the reel 421 of the winding disk 420, and then the hollow-walled wound tube 10 passes through the cooling assembly 450 and the orthopedic frame 460 in turn, and the cooling nozzle 452 sprays coolant on the hollow-walled wound tube 10 to achieve cooling; then the orthopedic frame 460 performs shaping, and finally a hollow-walled wound tube 10 that meets the requirements is obtained.

[0058] It is worth noting that, compared with the prior art, the production equipment 20 of the present invention has the characteristics of reducing production difficulty and production cost and improving production efficiency. That is, through the cooperation of the extrusion molding device 200, the winding device 400 and the wire unwinding device 500, the production equipment 20 of the present invention can continuously prepare the base tube 100 and the hollow wall winding tube 10, and realize automated production.

[0059] In particular, the production equipment 20 of the present invention can fill the steel wire 13 into the connection layer 12 while winding the base tube 100. As the next section of the base tube 100 and the previous section of the base tube 100 are squeezed against each other, the steel wire 13 will be clamped and then pulled as the base tube 100 is wound. In this way, there is no need to provide an additional driving source for the steel wire 13. It should be particularly emphasized that since the base tube 100 is provided with a receiving groove 101 and a convex ridge 102, when two adjacent sections of the base tube 100 are squeezed against each other, the steel wire 13 entering the gap will be held by the convex ridge 102 to ensure the depth, thereby limiting the position of the steel wire 13, so that the depth position of the wound steel wire 13 in the connection layer 12 is the same. In this way, the standardization of the hollow wall winding tube 10 is improved.

[0060] The present invention also provides a hollow wall wound pipe production process, which is based on the above-mentioned hollow wall wound pipe production equipment 20 to prepare a hollow wall wound pipe 10, and its main steps are as follows:

[0061] Step 1: Produce a base tube 100 by an extrusion molding device 200;

[0062] Step 2: The substrate tube 100 is initially cooled and shaped by the cooling device 300, and then enters the winding device 400. Specifically, the substrate tube 100 is wound on the winding disk 420, and spirally wound as the reel 421 rotates;

[0063] Step 3: The hot extrusion assembly 430 sprays the raw material of the connection layer 12 on the side wall of the base tube 100, and the steel wire 13 is pulled into the connection layer 12;

[0064] Step 4: The trimming assembly 440 squeezes the base tube 100 so that the section of the base tube 100 contacts and squeezes the previous section of the base tube 100, and the steel wire 13 is supported by the ridge 102. The trimming assembly 440 also smoothes the connection layer 12.

[0065] In this way, the base tube 100 is spirally wound together with the steel wire 13 , thereby forming the hollow-wall wound tube 10 .

[0066] In the present invention, the inner wall of the base tube 100 of the high-density polyethylene steel wire reinforced hollow wall winding tube 10 is also provided with steel wires. In the process of producing the base tube 100 by the extrusion molding device 200, the steel wires are placed at the die of the extrusion molding device 200, and the steel wires are covered by the molten high-density polyethylene, so that the inner wall of the base tube 100 is also embedded with steel wires, making the overall performance of the hollow wall winding tube more excellent.

[0067] In summary, the high-density polyethylene steel wire reinforced hollow wall wrapped tube 10, production equipment 20 and process thereof provided by the present invention can flatten the inner and outer sides of the tube wall 11, improve the overall strength of the hollow wall wrapped tube 10, and at the same time improve the degree of standardization, reduce production difficulty and production cost, and the built-in steel wire makes the overall tube body more corrosion-resistant and tear-resistant.

[0068] The above-mentioned embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
