Description

Technical Field

[0001] This invention relates to the field of PE pipe technology, and in particular to a nano-antibacterial PE water supply pipe and processing equipment. Background Technology

[0002] Polyethylene (PE) material, with its excellent strength, corrosion resistance, and non-toxic properties, has been widely used in the manufacture of water supply pipes. Because it is not prone to rust, it is considered an ideal replacement for traditional iron water supply pipes. However, some problems still need to be solved with existing technology:

[0003] In the daily use of water supply pipes, the water hammer effect generated when the inlet pipe is connected to the water flow will cause a strong impact on the connection of the inlet pipe. Over time, this impact may not only damage the sealing performance of the pipe, but also accelerate the aging of the waterproof cloth, leading to leakage. This poses a threat to the stable operation of the water supply system. PE pipes, with their excellent properties such as high strength, high temperature resistance, corrosion resistance, non-toxicity, and wear resistance, have been widely used in the field of water supply and drainage.

[0004] However, current PE pipe production processes, including injection molding, extrusion, cooling, and cutting, still have many shortcomings. For example, extruders consume a lot of energy and their temperature control is not precise enough; cooling equipment produces uneven cooling during pipe forming, which affects product quality.

[0005] Furthermore, plastic products, as everyday and industrial goods made primarily from plastic, also face challenges in their production process. The manufacture of plastic products typically involves multiple processes such as injection molding and thermoforming. Plastic is a material based on natural or synthetic resins, with various additives added, which can be molded under specific temperatures and pressures and maintain its shape at room temperature.

[0006] Melting raw materials is an essential step in processing plastic products. The molten plastic material is then extruded through an extrusion device and cooled to form the final product. However, existing hot-melt machines for PE pipe production typically use heating wires for bottom heating. This method is not only inefficient but also produces unsatisfactory mixing results because direct stirring by the agitator cannot achieve uniform material mixing. These problems urgently need to be addressed to improve production efficiency and product quality. While existing technologies may already offer solutions to these issues, this paper aims to provide an alternative or replacement solution. Summary of the Invention

[0026] Compared with existing technologies, the nano-antibacterial PE water supply pipe and processing equipment manufactured using the technical solution of this invention exhibit the following advantages: When the PE pipe is interrupted, the water hammer effect generated by the backflow preventer can produce a strong reverse force. This solution effectively transfers the kinetic energy generated by water hammer to these buffer structures through the design of buffer airbags, buffer hoses, buffer drainage pipes, and buffer outer airbags, thereby dissipating it. This design not only protects the pipeline and related equipment from water hammer damage but also improves the stability and reliability of the entire system. During the buffering process, gas is diverted to the buffer outer airbag through two pairs of buffer drainage pipes, while the gas flow is blocked by a horn-shaped flow restrictor. This design utilizes the principle of interference, causing the main airflow to interfere and be weakened, further improving the buffering effect. By rotating the external threaded pipe, a quick and stable connection to the PE pipe can be achieved. This connection method is not only simple to operate but also provides a strong connection, effectively preventing pipeline leakage. Furthermore, the use of T-shaped circular rubber rings and fitted sealing rubber rings further enhances the sealing and buffering performance of the connection. The entire design takes into account the safety and durability of the pipeline system. The buffer structure effectively prevents pipe ruptures or equipment damage caused by water hammer. Meanwhile, high-quality materials and precision manufacturing processes ensure the long-term stable operation of the entire system. The rational design and clear structure also simplify maintenance and upkeep. The use of fixing bolts and fitted ring blocks makes the replacement and repair of related components much easier.

[0027] The hot-melt extrusion stirring structure inside the hot-melt box allows for rapid hot melting of raw materials, improving production efficiency. The coordinated operation of the lifting and rotating drive motor, stirring shaft tube, stirring rod, and stirring blades enables rapid stirring at multiple angles and points, ensuring uniform mixing of the raw materials. Heating of the stirring shaft by a coiled inductor rod further enhances the stirring effect, making the hot melting of raw materials faster and more thorough. A complex cooling system, including a cooling box, a bidirectional cooling pump, a drain pipe, a spiderweb cooling shaft tube, and an L-shaped cooling pipe, achieves rapid and uniform cooling of both the inner and outer sides of the PE pipe, effectively avoiding temperature differences. The use of a cooler further enhances the cooling effect, ensuring the forming quality of the PE pipe. The design of the convex expansion cylindrical block, through the principle of magnetic repulsion, achieves rapid cooling and forming of the PE pipe and facilitates subsequent disassembly. The use of electromagnets and... Components such as lifting springs enable the lifting and lowering control of the stirring shaft and the convex expansion cylinder block, making operation more intelligent and precise. The linkage and coordination between various parts of the equipment, such as the lifting rotary drive motor and the stirring shaft tube, the lifting electromagnet and the lifting magnet, and the expansion electromagnet and the expansion magnet, all demonstrate a high degree of automation and intelligence. The combined use of the lifting concave sealing block and the lifting convex sealing block, as well as the application of the concave sealing ring, ensures good sealing performance of the feeding pipe, preventing raw material leakage and waste. The operation of a pair of horizontal screw modules allows for easy adjustment of the positions of the convex expansion cylinder block and the concave expansion block, giving the equipment greater flexibility and versatility when handling PE pipes of different specifications and lengths. The entire equipment is rationally designed, structurally stable, and the connections and coordination between various parts have been carefully considered to ensure safe and stable operation.

[0035] Those skilled in the art should connect all electrical components and their compatible power supplies in this case via wires, and should select appropriate controllers according to actual conditions to meet control requirements. The specific connection and control sequence should refer to the working principle described below, where the electrical components are connected in sequence. The detailed connection methods are well-known in the art. The following mainly introduces the working principle and process, without explaining the electrical control.

[0036] Example 1

[0037] like Figure 1-6 As shown in the hot melt box, the inner side of the PE pipe is equipped with a buffer structure and a buffer connection structure;

[0038] Specifically, the buffer structure includes: a buffer airbag, a buffer tubing, an outer buffer airbag, two pairs of buffer drainage tubes 407, two pairs of buffer ring blocks, two pairs of buffer springs, two pairs of concave ring blocks, two pairs of ring rubber rings, and several horn-shaped flow limiting plates.

[0039] Specifically, the buffer airbag is installed on the inner side of the PE tube, the buffer tubing is installed on the PE tube and the buffer airbag, the outer buffer airbag is installed on the outer side of the PE tube, two pairs of buffer drainage tubes 407 are inserted into the PE tube in a cross shape, and the two pairs of buffer drainage tubes 407 are connected to the buffer airbag and the outer buffer airbag, two pairs of buffer ring blocks are installed on the inner side of the buffer drainage tubes 407, two pairs of buffer springs are installed on the two pairs of buffer ring blocks, two pairs of concave ring blocks are respectively movably inserted into the inner side of the two pairs of buffer drainage tubes 407, and the two pairs of concave ring blocks are respectively connected to the two pairs of buffer springs, two pairs of ring rubber rings are respectively installed on the two pairs of concave ring blocks, and a plurality of horn-shaped limiting pieces are evenly inserted into the two pairs of concave ring blocks;

[0040] It should be noted that, as described above, when the flow in the PE pipe needs to be interrupted, the reverse force generated by the water hammer effect of the check valve is directed to the buffer airbag and the buffer hose on it. The gas inside the buffer airbag is then directed to the inside of the two pairs of buffer drainage pipes 407, and then to the outer buffer airbag through the two pairs of buffer drainage pipes 407. The outer buffer airbag is buffered by the atmospheric pressure on the outside, and at the same time, several horn-shaped flow restrictors block the gas being directed from the buffer airbag to the outer buffer airbag. The air inside the buffer drainage pipe 407 interacts with the incoming air, which causes the main airflow to be interfered with and weakened. At the same time, the horn-shaped flow restrictors drive the concave ring block on it, which in turn drives the ring rubber ring on it. The buffer spring also buffers the concave ring block, thereby driving the concave ring block to be buffered, thus dissipating the kinetic energy generated by the water hammer effect.

[0041] like Figure 1-6 As shown in the hot melt box, the buffer connection structure includes: a horn-shaped flow restrictor plate 201, a pair of connecting external threaded pipes 202, a T-shaped circular ring rubber ring 203, a pair of fitted circular ring blocks 204, a pair of fitted sealing rubber rings 205, and several fixing bolts.

[0042] Specifically, the horn-shaped flow restrictor 201 is fitted onto a pair of PE pipes, with threads on the outer side of each PE pipe. A pair of externally threaded connecting pipes 202 are respectively inserted into both sides of the horn-shaped flow restrictor 201 via a pair of bearings. A pair of externally threaded connecting pipes 202 are respectively fitted onto the outer side of the pair of PE pipes. A T-shaped circular rubber ring 203 is installed on the inner side of the horn-shaped flow restrictor 201. A pair of circular ring blocks 204 are respectively installed on the outer side of the pair of PE pipes. A pair of sealing rubber rings 205 are respectively installed on the pair of circular ring blocks 204. Several fixing bolts are respectively inserted into the pair of circular ring blocks 204 and the horn-shaped flow restrictor 201.

[0043] It should be noted that, as described above, a pair of externally threaded pipes 202 rotate on both sides of the horn-shaped flow restrictor 201 of the sleeve shaft tube. The rotating externally threaded pipes 202 engage with the outer threads of a pair of PE pipes, thereby connecting the pair of PE pipes. At the same time, the T-shaped ring rubber ring 203 on the inner side of the horn-shaped flow restrictor 201 of the sleeve shaft tube provides a quick buffer connection for the pair of PE pipes, thus buffering the connection point. Meanwhile, several fixing bolts connect the sleeve ring block 204 to the horn-shaped flow restrictor 201 of the sleeve shaft tube, and a pair of sleeve sealing rubber rings 205 provide buffering at the connection point.

[0044] Example 2

[0045] like Figure 1-6 As shown in the hot melt box, the extrusion guide convex tube is connected to the cooling box, the processing bracket is installed on the extrusion guide convex tube and the cooling box, the hot melt box is installed on the processing bracket, a hot melt extrusion stirring structure is installed on the inner side of the hot melt box, a rapid cooling structure is installed on the cooling box, and an extruder is provided on the extrusion guide convex tube;

[0046] Specifically, the hot melt extrusion mixing structure includes: a feeding pipe, a feeding air pump, a feeding air valve, a feeding sealing assembly, several mixing shaft pipes, several mixing shaft rods, several lifting limit gears, several lifting springs, several lifting electromagnets, several lifting magnets, a lifting rotation drive gear set for lifting magnets; 310, a lifting rotation drive motor 311, a coiled inductor rod 312, several mixing blades 313, and a temperature sensor;

[0047] Specifically, the feeding pipe is inserted into the hot melt box, the feeding air valve is connected to the hot melt box, the feeding air pump is connected to the feeding air valve, the feeding sealing assembly is installed on the feeding pipe, a plurality of stirring shaft tubes are evenly inserted into the top of the hot melt box, each of the stirring shaft tubes has a gear groove, a plurality of lifting limit gears are movably inserted into the inner side of the plurality of gear grooves, a plurality of stirring shaft rods are respectively inserted into the plurality of lifting limit gears, and a plurality of lifting springs are respectively installed on the inner side of the plurality of stirring shaft tubes, and the plurality of lifting springs A plurality of lifting electromagnets are respectively connected to a plurality of the lifting limit gears, a plurality of lifting electromagnets are respectively mounted on a plurality of the stirring shaft tubes, a plurality of lifting magnets are respectively mounted on a plurality of the lifting limit gears, a lifting rotation drive gear set lifting magnets 310 are mounted on a plurality of the stirring shaft tubes, a lifting rotation drive motor 311 is connected to the lifting rotation drive gear set lifting magnets 310, a coiled inductor rod 312 is mounted on the inner side wall of the hot melt box, a plurality of stirring blades 313 are respectively mounted on a plurality of the stirring shafts, and a temperature sensor is mounted on the hot melt box;

[0048] It should be noted that, as described above, the raw material is melted by the hot-melt extrusion and stirring structure inside the hot-melt box. The extruder inside the extrusion guide tube pushes the melted material to the rapid cooling structure inside the cooling box, where the melted material is rapidly cooled and shaped both inside and out. The material is poured into the inside of the feeding pipe, and the feeding sealing assembly is opened, allowing the material to flow along the feeding pipe to the inside of the hot-melt box. The lifting and rotating drive motor 311 operates, driving the lifting and rotating drive gear set on its drive end to lift the magnet. The lifting and rotating drive gear set 310 operates, lifting the magnet. 310 drives several stirring shafts to rotate, and the gear grooves on the inner side of the stirring shafts drive the lifting limit gears to rotate, thereby driving the stirring shafts to rotate stably. The stirring shafts then drive the stirring rods on them to rotate. The rotating blades 313, through the cooperation of several blades 313, rapidly heat-melt and stir the raw materials inside the hot melt box. Simultaneously, several lifting electromagnets on the stirring shaft tubes are energized, and each electromagnet magnetically attracts a lifting magnet. As these magnets are attracted one by one, several lifting limit gears are steadily raised and lowered along the gear grooves inside the stirring shaft tubes, thereby driving several stirring shafts to rise and fall vertically one by one, achieving multi-angle stirring with each lift. At the same time, several coiled inductor rods 312 inductively heat several stirring shafts, thereby rapidly heating several stirring shafts. These stirring shafts then perform multi-point stirring and heating inside the hot melt box. Simultaneously, several lifting springs vertically push the lifting limit gears, thereby driving stable lifting and pushing.

[0049] like Figure 1-6 As shown in the hot melt box, the cooling structure includes: a cooling forming tube 401, a cross-shaped flow support block 402, a spider web cooling shaft tube 403, a spider web flow splitting shaft tube 404, several L-shaped cooling tubes 405, a metal sleeve tube 406, a pair of flow pipes 407, a cooler 408, a radiator, and a cooling bidirectional flow pump.

[0050] Specifically, the cooling forming tube 401 is inserted into the cooling box, the cross-shaped flow support block 402 is installed inside the cooling forming tube 401, the metal sleeve tube 406 is inserted into the cross-shaped flow support block 402, the spider web cooling shaft tube 403 is inserted into the cross-shaped flow support block 402, the spider web diversion shaft tube 404 is installed on the metal sleeve tube 406, a plurality of L-shaped cooling tubes 405 are respectively connected to a plurality of spider web cooling shaft tubes 403 and a plurality of spider web diversion shaft tubes 404, a pair of flow tubes 407 are respectively inserted into the spider web diversion shaft tubes 404, the cooling bidirectional flow pump is connected to the flow tubes 407, the cooler 408 is installed inside the cooling box, and the radiator is installed outside the cooling box.

[0051] It should be noted that, in the above process, the raw material is pushed to the inside of the cooling forming tube 401 by the extrusion guide convex tube, the liquid inside the cooling tank is guided to the inside of the guide tube 407 by the cooling bidirectional guide pump, the liquid is guided to the inside of the spider web cooling shaft tube 403 by the guide tube 407, the low-temperature liquid is guided to several L-shaped cooling tubes 405 by the spider web cooling shaft tube 403, the low-temperature liquid is guided to the inside of the spider web distribution shaft tube 404 by the several L-shaped cooling tubes 405, and the low-temperature liquid is guided to the inside of several other L-shaped cooling tubes 405 by the spider web distribution shaft tube 404, thereby guiding the liquid to the spider web. The cooling shaft guides the heat-absorbing liquid to the inside of another drain pipe 407 via the spider web cooling shaft, allowing the low-temperature liquid to flow inside the metal sleeve pipe 406, thereby rapidly cooling the inside of the PE pipe. This achieves rapid internal and external cooling of the PE pipe. Simultaneously, the cooler 408 rapidly cools the inside of the cooling box. The low temperature of the spider web cooling shaft pipe 403, several L-shaped cooling pipes 405, and the spider web diversion shaft pipe 404 further promotes rapid cooling. The bidirectional operation of the cooling bidirectional drain pump avoids the occurrence of cooling temperature differences.

[0052] like Figure 1-6 As shown in the hot melt box, the feeding sealing assembly includes: a lifting concave sealing block, a lifting convex sealing block, a sealing hydraulic push rod, a pair of sealing limit shafts, and a concave sealing rubber ring;

[0053] Specifically, the lifting concave sealing block is inserted into the feeding pipe, the lifting convex sealing block is movably inserted into the inner side of the lifting concave sealing block, the sealing hydraulic push rod is installed on the inner side of the lifting concave sealing block, and the pushing end of the sealing hydraulic push rod is connected to the lifting convex sealing block, a pair of sealing limiting shafts are respectively inserted into the lifting concave sealing block, and a pair of sealing limiting shafts are movably inserted into the lifting convex sealing block, and the concave sealing rubber ring is installed on the lifting convex sealing block;

[0054] It should be noted that, as described above, the extension and retraction of the sealing hydraulic push rod on the inner side of the lifting concave sealing block drives the lifting convex sealing block on the pushing end of the sealing hydraulic push rod, thereby causing the lifting convex sealing block to rise and fall stably along the inner side of the lifting concave sealing block. The lifting convex sealing block squeezes and seals the feeding pipe, while the concave sealing ring on the lifting convex sealing block provides a flexible seal for the feeding pipe.

[0055] like Figure 1-6 As shown in the hot melt box, an expansion assembly is mounted on the processing bracket;

[0056] Specifically, the expansion bracket includes: a convex expansion cylindrical block, a concave expansion block, an expansion electromagnet, an expansion magnet, and a pair of horizontal lead screw modules;

[0057] Specifically, a pair of horizontal lead screw modules are installed in parallel on the processing bracket, the concave expansion block is installed on the moving end of the pair of horizontal lead screw modules, the convex expansion cylindrical block is movably inserted into the inner side of the concave expansion block, the expansion electromagnet is installed on the inner side of the concave expansion block, and the expansion magnet is installed on the convex expansion cylindrical block.

[0058] It should be noted that, as described above, the operation of a pair of horizontal lead screw modules drives the concave expansion block on the moving end of the horizontal lead screw module. The expansion electromagnet inside the concave expansion block is energized, and the expansion electromagnet magnetically repels the expansion magnet. The expansion magnet drives the convex expansion cylindrical block on it. By movably inserting the convex expansion cylindrical block into the inner side of the cooling and forming tube 401, rapid cooling and forming are achieved. At the same time, the operation of the pair of horizontal lead screw modules changes the position of the convex expansion cylindrical block and the concave expansion block, thereby causing the convex expansion cylindrical block to retract to the outer side of the cooling and forming tube 401, which facilitates the subsequent forming and disassembly of the PE tube.

[0059] As a preferred embodiment, the inner sides of the spider web cooling shaft tube 403 and the spider web diversion shaft tube 404 are respectively provided with a pair of diversion plates.

[0060] As a preferred embodiment, furthermore, a Tesla valve tube is provided on the inner side of each of the L-shaped cooling pipes 405.

[0061] As a preferred embodiment, a pressure sensor is further provided on the inside of the hot melt box.

[0062] As a preferred embodiment, a temperature sensor is further provided on the inside of the cooling box.

[0063] The above technical solutions only embody the preferred technical solutions of the present invention. Any modifications that may be made by those skilled in the art to certain parts thereof embody the principles of the present invention and fall within the protection scope of the present invention.
