Description

Technical Field

[0001] This invention relates to the field of nylon corrugated pipe manufacturing technology, and in particular to a blow molding and shaping system for nylon corrugated flexible tubing used in rail transit protective cables. Background Technology

[0002] With the widespread use of electrical wires and water pipes, certain protective measures are needed to reduce the impact of the external environment on them and extend their service life. Currently, this is generally achieved by covering the outside of the wires and pipes with protective tubes, mostly nylon corrugated pipes, which have the advantages of low cost, corrosion resistance, long service life, and easy installation. However, during the production of corrugated pipes, which involves extrusion and cooling, the extrusion mold inevitably experiences high temperatures, requiring periodic cooling treatment, thus directly affecting production efficiency.

[0003] Patent publication number 202010197144.6 discloses an integrated molding method for PVC corrugated pipes. This method involves controlling the flow range of cooling water, requiring a combination of molds on both sides for cooling water circulation. It also ensures that the cooling water pipes do not become tangled when the water tank rotates. However, this device does not consider impurities present in the cooling water itself or within the pipes during the cooling water entry process. The flow of cooling water inevitably leads to impurity sedimentation and accumulation. When impurities accumulate and cause blockage at the magnetic attraction points, the two repulsive magnets may not move or only one end may move, resulting in poor cooling water flow within the mold. Furthermore, when the mold rotates under the drive of the equipment, the two separate rotary joints cannot solve the problem; it's as if the water tank and pump are stationary while the pipes rotate, causing the pipes to twist and become tangled. Therefore, we propose a method that cools a single mold without causing tangling or knotting of the cooling water pipes, allowing for more effective cooling of individual molds.

[0004] Therefore, based on the above, and drawing on years of experience in design, development and manufacturing in the relevant industry, the inventor has researched and improved the existing structure and its shortcomings, and provides a blow molding system for nylon corrugated hoses for rail transit protective cables, in order to achieve a more practical purpose.

[0036] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, 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. Example

[0037] Reference Figure 1-11A blow molding and shaping system for nylon corrugated flexible tubing used in rail transit protective cables includes a chassis 1. Extension frames 2 are provided around the chassis 1, and an assembly frame 4 is provided on the top surface of the extension frames 2. A rotating sleeve 10 is mounted on the top bearing of the assembly frame 4. Two mounting holes are provided on the top surface of the assembly frame 4, allowing the rotating sleeve 10 to be mounted within them via the bearing assembly, enabling free rotation. A cooling machine body 11 is fixedly bolted to the top surface of the rotating sleeve 10. The model of the cooling machine body 11 can be replaced and adjusted according to actual production needs, and is not limited to a single model, as long as it can adequately cool the cooling water pumped into the cooling machine body 11 from the return water tank 13. A water outlet tank 12 and a water return tank 13 are suspended from the bottom surface of the rotating sleeve 10. The water outlet tank 12 and the water return tank 13 are of the same type of liquid container. The pipe at the output end of the cooler body 11 extends to the top of the inner cavity of the outlet water tank 12, and the pipe at the input end of the cooler body 11 extends to the bottom of the inner cavity of the return water tank 13, facilitating the extraction of cooling water from the return water tank 13. The cooler body 11 is equipped with a pump to pump the used cooling water from the return water tank 13 and pump the cooling water that has been cooled and circulated by the cooler body 11 into the outlet water tank 12 for use through the pipe at the output end of the cooler body 11. The inner cavity of the outlet water tank 12 is equipped with a telescopic mechanism 14. The bottom surfaces of both the outlet water tank 12 and the return water tank 13 need to have space to accommodate the inner sleeve 141, facilitating the direct welding of the inner sleeve 141 to the outlet water tank 12 or the return water tank 13 to form a sealed assembly. The bottom surface of the chassis 1 is equipped with a drive motor 3, which provides power output for the entire production system. The specific model of the drive motor 3 can be selected according to production needs.

[0038] Specifically, the telescopic mechanism 14 includes an inner cylinder 141, the outer surface of which is fixedly fitted into the inner cavity of the water outlet tank 12. Two guide cylinders 142 are fitted onto the bottom surface of the inner cylinder 141. A guide rod 143 is inserted through the top surface of each guide cylinder 142, with its bottom end extending into the interior of the guide cylinder 142. A stop plate 144 is connected to the bottom end of the guide rod 143. The outer surface of the guide rod 143 is fitted between the top surface of the inner cavity of the guide cylinder 142 and the top surface of the stop plate 144. The return spring 145, the top end of the guide rod 143 is provided with a connecting strip 146, the middle of the top surface of the connecting strip 146 is provided with a tube-through ring 147, the bottom surface of the inner cylinder 141 is provided with two tube-through holes 148, the tube-through holes 148 on the bottom surface of the inner cylinder 141 can meet the insertion of the fixed tube assembly 15, the liquid guide tube 121 and the return tube 131, and the fitting between the tube-through holes 148 and the fixed tube assembly 15 is fixed, so that the fixed tube assembly 15 cannot be extended or retracted. The liquid guide tube 121 and the return tube 131 Both are made of corrugated flexible tubing to facilitate the extension and retraction of the spring, allowing the liquid guide tube 121 and return tube 131 to retract into their respective positions within the inner sleeve 141. The guide sleeve 142 primarily provides space for the insertion of the guide rod 143 and the anti-shift plate 144, and, in conjunction with the anti-shift plate 144, limits the elastic deformation of the return spring 145. When the liquid guide tube 121 and return tube 131 are extended, the tube ring 147 will cause the connecting strip 146 to move downwards, pushing the guide rod 143 into the inner sleeve 142. The top surface of the anti-shift plate 144 needs to be fixedly connected to the bottom end of the return spring 145, and the top surface of the inner cavity of the guide cylinder 142 needs to be fixedly connected to the top end of the return spring 145, so that the return spring 145 can be stretched when the guide rod 143 is pushed into the guide cylinder 142. When it is necessary to retract the liquid guide tube 121 and the return tube 131, the elastic deformation of the return spring 145 will be restored and contracted, which plays the role of pulling the liquid guide tube 121 and the return tube 131 into their respective inner cylinders 141.

[0039] Specifically, the fixed pipe assembly 15 includes a first fixed pipe 151 and a second fixed pipe 152. The top end of the first fixed pipe 151 is connected to the bottom surface of the outlet tank 12, and the other end of the first fixed pipe 151 is connected to the end of the liquid guide pipe 121. The top end of the second fixed pipe 152 is connected to the bottom surface of the return tank 13, and the other end of the second fixed pipe 152 is connected to the end of the return pipe 131. The configuration of the first fixed pipe 151 serves to fix the end position of the liquid guide pipe 121 as it extends and retracts. The configuration of the second fixed pipe 152 serves to fix the end position of the return pipe 131 as it extends and retracts. This allows the liquid guide pipe 121 to communicate with the inside of the outlet tank 12 through the first fixed pipe 151, and the return pipe 131 to communicate with the inside of the return tank 13 through the second fixed pipe 152. One end of the first fixed pipe 151 inside the outlet tank 12 is connected to a pump, and one end of the second fixed pipe 152 inside the return tank 13 is connected to a pump.

[0040] Specifically, the top of the output shaft of the drive motor 3 is connected to a drive gear 5, the right end bearing of the top surface of the chassis 1 is mounted with a driven gear 6, the top surface of the drive gear 5 is mounted with a drive turntable 51, the top surface of the driven gear 6 is mounted with a driven turntable 61, the outer surface of the drive gear 5 is chain-sleeved with a transmission chain 7, the other end of the transmission chain 7 is chain-sleeved with the outer surface of the driven gear 6, the outer surface of the transmission chain 7 is mounted with a mold body 8, the outer surfaces of the drive turntable 51 and the driven turntable 61 are wrapped with a silicone transmission strip 9, the outer ring of the top surface of the silicone transmission strip 9 has a first groove 91, the inner ring of the top surface of the silicone transmission strip 9 has a second groove 92, and the middle of the right side of the top surface of the extension frame 2 is provided with a discharge roller 16. The output shaft of the drive motor 3 needs to be fixedly connected to the drive gear 5 so that the output shaft of the drive motor 3 can drive the drive gear 5 to rotate, thus driving the entire device. The external shaft of the driven gear 6 is fitted with a bearing on the top surface of the chassis 1, which serves as a positioning and guiding function, without power output. In conjunction with the installation of the drive turntable 51 and the driven turntable 61, it can drive the silicone transmission strip 9 synchronously and in the same direction. The transmission chain 7 can be set to rotate in conjunction with the tooth grooves on the outer surface of the drive gear 5 and the driven gear 6, thus guiding and driving the mold body 8. The silicone transmission strip 9 provides space for the installation of the water guide ring pipe 911 and the drainage ring pipe 921, preventing the water guide ring pipe 911 and the drainage ring pipe 921 from being assembled together with the mold body 8.

[0041] Specifically, a water guide ring pipe 911 is embedded inside the first groove 91, and a drain ring pipe 921 is embedded inside the second groove 92. A water inlet pipe 81 is connected to the left end of the top surface of the mold body 8, and a water outlet pipe 82 is connected to the right end of the top surface of the mold body 8. The outer surface of the water guide ring pipe 911 is connected to the end of the water inlet pipe 81, and the outer surface of the drain ring pipe 921 is connected to the end of the drain pipe 82. The opening of the first groove 91 provides space for the installation of the water guide ring pipe 911, and the opening of the second groove 92 provides space for the installation of the drain ring pipe 921, so that the water inlet pipe 81 and the water guide ring pipe 911 are connected, and the water outlet pipe 82 and the drain ring pipe 921 are connected. The first groove 91 allows the water inlet pipe 81 to pass through it and connect with the water guide ring pipe 911, and the second groove 92 allows the water outlet pipe 82 to pass through it and connect with the drain ring pipe 921.

[0042] Specifically, there are two rotating sleeve blocks 10, and the two rotating sleeve blocks 10 are evenly distributed and mounted on the top surface of the assembly frame 4. The input end of the cooler body 11 extends into the bottom of the inner cavity of the return water tank 13, and the output end of the cooler body 11 extends into the top of the inner cavity of the outlet water tank 12. By setting the number of rotating sleeve blocks 10, they are used in conjunction with two sets of mold bodies 8 for hoisting and installation, and are correspondingly installed above the mold bodies 8, so that the assembly frame 4 provides support for them. The length of the pipes at the output end and input end of the cooler body 11 extending into the interior of the outlet water tank 12 and the return water tank 13 has been described.

[0043] Specifically, the size and shape of the through hole 148 are adapted to the size and shape of the fixed tube assembly 15. The port of the through hole 148 is fixedly connected to the outer surface of the fixed tube assembly 15, and the other port of the through hole 148 is movably connected to the liquid guide tube 121. The through hole 148 provides a channel for inserting the liquid guide tube 121 and the return tube 131 into the internal space of the inner tube 141, and also provides a fixed fit for the fixed tube assembly 15.

[0044] Specifically, the inner cavity of the mold body 8 is provided with a circulation pipe 83. The inlet and outlet ends of the circulation pipe 83 are connected to the ends of the inlet pipe 81 and the outlet pipe 82, respectively. The number of inlet pipes 81 connected is consistent with the number of mold bodies 8 used, and the number of outlet pipes 82 connected is consistent with the number of mold bodies 8 used. Both the inlet pipe 81 and the outlet pipe 82 are connected to external pipes. The number of pipes used needs to match the number of mold bodies 8 used, so that each mold body 8 can be cooled and circulated separately. The circulation pipe 83 is opened in the inner cavity of the mold body 8 and is connected to the inlet pipe 81 and the outlet pipe 82. Cooling water can enter the interior of the circulation pipe 83 through the inlet pipe 81 and then flow out through the outlet pipe 82 from the interior of the circulation pipe 83, which can cool the mold body 8.

[0045] Specifically, the outer end of the liquid guide pipe 121 is connected to the outer surface of the water guide ring pipe 911, and the outer end of the return pipe 131 is connected to the outer surface of the drain ring pipe 921. The connection between the liquid guide pipe 121 and the water guide ring pipe 911 allows the liquid guide pipe 121 to guide the cooling water inside the water outlet tank 12 into the water guide ring pipe 911, and then guide it through the water inlet pipe 81 into the circulation pipe 83 opened inside the mold body 8 for cooling. Then, through the circulation pipe 83, the water with temperature is guided through the water outlet pipe 82 into the drain ring pipe 921. The pump inside the return water tank 13 draws out the cooling water with temperature and guides it through the return water tank 13 into the interior of the cooling machine body 11 for cooling circulation.

[0046] Specifically, a through hole is provided in the middle of the through ring 147. The size and shape of the through hole are adapted to the size and shape of the liquid guide tube 121. The through hole allows the liquid guide tube 121 and the return tube 131 to pass through it, and then the liquid guide tube 121 is connected to the first fixed tube 151, and the return tube 131 is connected to the second fixed tube 152.

[0047] Specifically, a guide groove is provided on the outer ring of the top surface of the chassis 1, and a guide vertical roller 71 is connected to the bottom bearing of the transmission chain 7. The size and shape of the guide vertical roller 71 are adapted to the size and shape of the guide groove. The opening of the guide groove can cooperate with the guide vertical roller 71 to provide a transmission-type guiding function for the transmission chain 7, so as to avoid jamming and gaps between the mold bodies 8.

[0048] Working Principle: In this invention, firstly, the drive motor 3 is turned on, causing the output shaft of the drive motor 3 to drive the active gear 5 to rotate. This allows the active gear 5 to engage with the driven gear 6 to perform gear-type transmission on the transmission chain 7. Then, the mold body 8 extrudes and blow-moldes the corrugated pipe material. During the extrusion process, the rotating sleeve 10 synchronously drives the outlet water tank 12 and the return water tank 13 to rotate at the same speed and in the same direction as the mold body 8. Simultaneously, the cooling machine body 11 is turned on, allowing the water inside the outlet water tank 12, along with its internal pump, to flow through the liquid guide pipe 121 and the first fixed pipe 151, into the water guide ring pipe 911. The water then flows through the water inlet pipe 81 into the circulation pipe 83, enabling the mold body 8 to undergo cooling. This allows the raw material in contact with the outer surface of the mold body 8 to be blow-molded and shaped more quickly, and reduces the temperature of the mold body 8. Through the heat conduction of the mold body 8, the heat is conducted to the cooling water, causing the cooling water to heat up. It is then introduced into the outlet pipe 82 through the circulation pipe 83, and then into the interior of the drain ring pipe 921. The pump inside the return water tank 13 introduces the water into the return water tank 13 through the return pipe 131 and the first fixed pipe 152, and then pumps it into the interior of the cooling machine body 11 for cooling circulation. The cooled water after cooling is introduced back into the outlet water tank 12 for the next round of cooling circulation. During the production process of the mold body 8, the silicone transmission strip 9 can synchronously drive the water guide ring pipe 911 and the drain ring pipe 921 to rotate synchronously in the same direction.
