Description

Technical Field

[0001] This invention belongs to the field of spiral wound tube technology, specifically a spiral wound tube production process. Background Technology

[0002] Krah pipe (HDPE spiral wound structured wall type B pipe) is manufactured using a hot-winding molding process and is mainly used for municipal underground drainage, sewage, rainwater collection, water supply, and ventilation. It can also be used as seepage and drainage pipes for railways, highways, golf courses, football fields, etc. Due to the excellent acid, alkali, and corrosion resistance of polyethylene and polypropylene materials, they are widely used in nuclear power plants, steel plants, power plants, petrochemical plants, docks, and railway stations, especially in harsh environments such as tidal flats, saline-alkali land, seabeds, soft foundation expansive soil, and earthquake zones.

[0003] In the existing technology, during the production of spiral wound tubes, when the small spiral tubes are wound onto the large round tube of the base, a section is exposed to the external environment. Generally, the spiral tubes are placed in the coating box in an uncleaned state for coating with adhesive materials, and then enter the final hot melt bonding state. The spiral tubes exposed to the external environment are subject to impurities from the external factory environment, which will greatly affect the coating of adhesive materials and the hot melt bonding effect in the later coating box. Therefore, the present invention provides a spiral wound tube production process. Summary of the Invention

[0004] To overcome the shortcomings of existing technologies and solve the problem that during the production of spiral wound tubes, a section of the small spiral wound tube is exposed to the external environment when it is being wound onto the large round tube of the base. Generally, the small spiral wound tube is placed in the coating box in an uncleaned state for coating and bonding materials, and then enters the final hot melt bonding state. The small spiral wound tube exposed to the external environment is subject to impurities from the external factory environment, which greatly affects the coating and bonding materials and the hot melt bonding effect in the later coating box. This invention proposes a spiral wound tube production process.

[0005] The technical solution adopted by this invention to solve its technical problem is as follows: a spiral wound tube manufacturing process described in this invention, the manufacturing process is as follows:

[0006] S1: Start the winding machine body and use the extrusion unit on the winding machine to melt and extrude the material of the large round tube of the chassis, and then evenly wind it onto the heated steel die roller.

[0007] S2: The produced wound tubes are pulled through the coating box by the traction device. When the wound tubes enter the coating box, the surface of the pulled wound tubes is cleaned by the cleaning component.

[0008] S3: The coating box applies adhesive to the surface of the wound tube, performs slight heat melting, and then winds it at a specified angle onto the outer surface of the uniformly coiled large round tube for heat melting bonding.

[0009] S4: During the winding process, the surface of the winding tube is cooled and shaped by water spraying through a cooling component, and then cut into sections to obtain the required winding tube;

[0010] In the existing technology, during the production of spiral wound tubes, when the small spiral tubes are pulled and wound onto the large round tube of the base, a section is exposed to the external environment. Generally, the spiral tubes enter the coating box in an uncleaned state for coating and bonding materials, and then enter the final hot melt bonding state. The spiral tubes exposed to the external environment are subject to impurities from the external factory environment, which will greatly affect the coating and bonding materials and the hot melt bonding effect in the later coating box. To address this, a cleaning component is provided. Meanwhile, the extruder, traction device and coating box mentioned above are all existing technologies and will not be described here.

[0011] Preferably, a steel die roller is provided on the side wall of the winding machine body; a coating box is fixedly connected to the side wall of the winding machine body via a pipe; a first through hole is provided in the coating box, and a coating assembly is provided inside the coating box; a cleaning assembly is provided on the side wall of the coating box; the cleaning assembly includes an annular plate; an annular plate is rotatably connected to the side wall of the coating box; a set of symmetrically distributed fixing plates are fixedly connected to the inner wall of the annular plate; a first rotating shaft is rotatably connected between a pair of fixing plates; a sponge layer is adhered to the outer wall of the first rotating shaft; a guide wheel is rotatably connected to the side wall of the winding machine body via an L-shaped rod; the annular plate rotates via a power component; during operation, in When the wound tube is initially pulled through the coating box by the traction device, the power component is activated to rotate the annular plate. The rotation of the annular plate causes the sponge layer on the first rotating shaft to rotate around the center line of the first through hole. The sponge layer then wipes and cleans the surface of the wound tube, preventing impurities from the external factory environment from adhering to the wound tube during the traction process. This would affect the bonding effect of the coating material and the hot melt bonding effect in the subsequent coating box. At the same time, the sponge layer rotates around the first rotating shaft, preventing the sponge layer and the wound tube from being in a fixed position for a long time, which would lead to excessive local impurities on the sponge layer and affect the cleaning effect.

[0012] Preferably, the power component includes an electric motor; the top of the coating box is fixedly connected to the electric motor; the output end of the electric motor is provided with a second rotating shaft; a first gear is fixedly connected to the end of the second rotating shaft; a first annular rack is fixedly connected to the outer wall of the annular plate; the first gear and the first annular rack mesh with each other; during operation, when the electric motor is started, the electric motor will drive the second rotating shaft to rotate, the rotation of the second rotating shaft will drive the first gear to rotate, which in turn will drive the first annular rack to rotate, which in turn will drive the annular plate to rotate, and the rotation of the annular plate will drive the sponge layer on the first rotating shaft to rotate around the center line of the first through hole, thereby wiping and cleaning the surface of the wound tube through the sponge layer.

[0013] Preferably, the cross-sectional view of the sponge layer is elliptical. During operation, setting the sponge layer to be elliptical facilitates the traction device when pulling the wound tube. At this time, because the sponge layer is elastic and soft, it will not affect the winding tube from entering the first through hole. At the same time, when the winding tube is pulled and moved, the sponge layer can fit tightly against the winding tube, which facilitates the cleaning of the surface of the winding tube.

[0014] Preferably, a first arc-shaped plate is fixedly connected to the side wall of the coating box, and the first arc-shaped plate is located directly below the annular plate; a fixed rod is fixedly connected to the first arc-shaped plate, and a second annular rack is fixedly connected to the top of the fixed rod; the end of the first rotating shaft passes through the fixed plate and is fixedly connected to a second gear; the second gear and the second annular rack mesh with each other; during operation, when the first rotating shaft rotates with the annular plate, since the first arc-shaped plate and the fixed rod are both in a fixed state, the second annular rack is also in a fixed state. Then, through the meshing of the second gear and the second annular rack, the first rotating shaft is driven to rotate on its own axis while rotating with the annular plate. This allows the sponge layer to roll easily, making it easier for impurities to fall off, and also effectively preventing the local accumulation of impurities from affecting the wiping and cleaning effect of the sponge layer.

[0015] Preferably, the annular plate has a set of arc-shaped through slots, and the arc-shaped through slots are located directly below the sponge layer; the side wall of the fixed rod has a second arc-shaped plate, and a set of cleaning brushes are fixedly connected to the second arc-shaped plate, and the cleaning brushes are soft brushes; during operation, the arc-shaped through slots are located directly below the sponge layer on the annular plate. When the annular plate rotates, the cleaning brushes, being soft brushes, will enter the annular plate through the arc-shaped through slots and come into contact with the sponge layer. Then, by utilizing the rotation of the sponge layer around the first rotation axis, the sponge layer can be thoroughly cleaned. The second arc-shaped plate is located at the lowest point of the annular plate, which facilitates the falling off of impurities.

[0016] Preferably, a pair of magnetic strips symmetrically distributed about the arc-shaped through groove are fixed to the outer wall of the annular plate; the second arc-shaped plate is magnetic, and the second arc-shaped plate and the magnetic strips attract each other; a guide groove is provided on the side wall of the fixing rod; a guide block is fixed to the side wall of the second arc-shaped plate, and the guide block is slidably connected to the inner wall of the guide groove; during operation, since the magnetic strips are distributed on both sides of the arc-shaped through groove, when the annular plate rotates, the magnetic strips and the second arc-shaped plate attract each other, which will drive the second arc-shaped plate to move upward, thereby increasing the adhesion of the cleaning brush. At the same time, when the magnetic strips and the second arc-shaped plate are misaligned, the second arc-shaped plate will suddenly move downward, which has a sudden force and can facilitate the self-cleaning operation of the cleaning brush.

[0017] Preferably, a set of discharge troughs is provided on the second arc-shaped plate, and the discharge troughs and cleaning brushes are arranged alternately; during operation, the discharge troughs can be used to collect impurities and drop them onto the first arc-shaped plate, which facilitates subsequent cleaning work.

[0018] Preferably, the second arc-shaped plate, the first arc-shaped plate, and the annular plate are arranged parallel to each other; during operation, the cleaning brush can easily clean the sponge layer through the arc-shaped groove, and the parallel arrangement of the three avoids the influence of movement interference.

[0019] The beneficial effects of this invention are as follows:

[0020] 1. The spiral wound tube production process of the present invention involves driving a ring plate to rotate via a power component. The rotation of the ring plate causes a sponge layer on a first rotating shaft to rotate around the center line of a first through hole. This allows the sponge layer to wipe and clean the surface of the spiral wound tube, preventing impurities from the external factory environment from adhering to the exposed spiral wound tube during the traction process. This would affect the bonding of the adhesive material and the hot melt bonding effect in the subsequent coating box. At the same time, the rotation of the sponge layer around the first rotating shaft prevents the sponge layer and the spiral wound tube from remaining in a fixed position for a long time, which could lead to excessive local impurities on the sponge layer and affect the cleaning effect.

[0021] 2. The spiral tube production process of the present invention involves fixing the first arc-shaped plate and the fixing rod, fixing the second annular rack, and then engaging the second gear and the second annular rack to drive the first rotating shaft to rotate while following the rotation of the annular plate. This allows the sponge layer to roll easily, facilitating the removal of impurities and effectively preventing the accumulation of impurities in certain areas from affecting the wiping and cleaning effect of the sponge layer.

[0041] Example 1:

[0042] like Figures 1 to 5 As shown, the present invention provides a spiral wound tube manufacturing process, the manufacturing process of which is as follows:

[0043] S1: Start the winding machine body 1, use the extrusion unit on the winding machine to melt and extrude the material of the large round tube of the chassis, and then evenly wind it onto the heated steel die roller;

[0044] S2: The produced wound tubes are passed through the coating box 12 by the traction device. When the wound tubes enter the coating box 12, the surface of the wound tubes is cleaned by the cleaning component 14.

[0045] S3: The coating box 12 applies adhesive to the surface of the wound tube, performs slight heat melting, and then winds it at a specified angle onto the outer surface of the uniformly coiled large round tube for heat melting bonding.

[0046] S4: During the winding process, the surface of the winding tube is cooled and shaped by water spraying through a cooling component, and then cut into sections to obtain the required winding tube;

[0047] In the prior art, during the production of spiral wound tubes, when the small spiral wound tubes are pulled and wound onto the large round tube of the base, a section is exposed to the external environment. Generally, the tubes enter the coating box 12 in an uncleaned state for coating and bonding materials, and then enter the final hot melt bonding state. The spiral wound tubes exposed to the external environment are subject to impurities from the external factory environment, which will greatly affect the coating and bonding materials and the hot melt bonding effect in the coating box 12. Therefore, a cleaning component 14 is provided for cleaning. Meanwhile, the extruder, traction device and coating box 12 mentioned above are all prior art and will not be described here.

[0048] Preferably, a steel die roller is provided on the side wall of the winding machine body 1; a coating box 12 is fixedly connected to the side wall of the winding machine body 1 via a pipe 11; a first through hole 13 is provided in the coating box 12, and a coating assembly is provided inside the coating box 12; a cleaning assembly is provided on the side wall of the coating box 12; the cleaning assembly includes an annular plate 15; the annular plate 15 is rotatably connected to the side wall of the coating box 12; a set of symmetrically distributed fixing plates 16 are fixedly connected to the inner wall of the annular plate 15; a first rotating shaft 17 is rotatably connected between a pair of fixing plates 16; a sponge layer 18 is adhered to the outer wall of the first rotating shaft 17; a guide wheel is rotatably connected to the side wall of the winding machine body 1 via an L-shaped rod; the annular plate 15 is rotated by a power component. During operation, when the wound tube is initially pulled through the coating box 12 by the traction device, the power component is activated to rotate the annular plate 15. The rotation of the annular plate 15 causes the sponge layer 18 on the first rotating shaft 17 to rotate around the center line of the first through hole 13. The sponge layer 18 then wipes and cleans the surface of the wound tube, preventing impurities from the external factory environment from adhering to the wound tube exposed to the external environment during the traction process, which would affect the bonding material and hot melt bonding effect of the coating in the coating box 12. At the same time, the sponge layer 18 rotates around the first rotating shaft 17, preventing the sponge layer 18 and the wound tube from being fixed in position for a long time, which would lead to excessive local impurities on the sponge layer 18 and affect the cleaning effect.

[0049] The power component includes an electric motor 2; the top of the coating box 12 is fixedly connected to the electric motor 2; the output end of the electric motor 2 is provided with a second rotating shaft 21; a first gear 22 is fixedly connected to the end of the second rotating shaft 21; a first annular rack 23 is fixedly connected to the outer wall of the annular plate 15; the first gear 22 and the first annular rack 23 mesh with each other; when working, the electric motor 2 is turned on, the electric motor 2 will drive the second rotating shaft 21 to rotate, the second rotating shaft 21 will drive the first gear 22 to rotate, and then drive the first annular rack 23 to rotate, and then drive the annular plate 15 to rotate. The rotation of the annular plate 15 will drive the sponge layer 18 on the first rotating shaft 17 to rotate around the center line of the first through hole 13, and then wipe and clean the surface of the wound tube through the sponge layer 18.

[0050] The cross-sectional view of the sponge layer 18 is elliptical. During operation, the sponge layer 18 is set to be elliptical, which facilitates the traction device to pull the wound tube. At this time, because the sponge layer 18 is elastic and soft, it will not affect the winding tube from entering the first through hole 13. At the same time, when the winding tube is pulled and moved, the sponge layer 18 can fit tightly against the winding tube, which is convenient for cleaning the surface of the winding tube.

[0051] A first arc-shaped plate 24 is fixedly connected to the side wall of the coating box 12, and the first arc-shaped plate 24 is located directly below the annular plate 15; a fixing rod 25 is fixedly connected to the first arc-shaped plate 24, and a second annular rack 26 is fixedly connected to the top of the fixing rod 25; the end of the first rotating shaft 17 passes through the fixing plate 16 and is fixedly connected to a second gear 27; the second gear 27 and the second annular rack 26 mesh with each other; during operation, when the first rotating shaft 17 rotates with the annular plate 15, since the first arc-shaped plate 24 and the fixing rod 25 are both in a fixed state, the second annular rack 26 is also in a fixed state. Then, through the meshing of the second gear 27 and the second annular rack 26, the first rotating shaft 17 is driven to rotate on its own axis while rotating with the annular plate 15, which facilitates the rolling of the sponge layer 18, making it easier for impurities to fall off, and also effectively preventing the local accumulation of impurities from affecting the wiping and cleaning effect of the sponge layer 18.

[0052] The annular plate 15 has a set of arc-shaped through grooves 3, which are located directly below the sponge layer 18. The side wall of the fixed rod 25 has a second arc-shaped plate 31, and a set of cleaning brushes 32 are fixedly connected to the second arc-shaped plate 31. The cleaning brushes 32 are soft brushes. During operation, the arc-shaped through grooves 3 are located directly below the sponge layer 18. When the annular plate 15 rotates, the cleaning brushes 32, being soft brushes, will enter the annular plate 15 through the arc-shaped through grooves 3 and come into contact with the sponge layer 18. Then, by utilizing the rotation of the sponge layer 18 around the first rotating axis 17, the sponge layer 18 can be thoroughly cleaned. The second arc-shaped plate 31 is located at the lowest point of the annular plate 15, which facilitates the falling off of impurities.

[0053] A pair of magnetic strips 33 are fixedly attached to the outer wall of the annular plate 15, symmetrically distributed about the arc-shaped through groove 3; the second arc-shaped plate 31 is magnetic, and the second arc-shaped plate 31 and the magnetic strips 33 attract each other; a guide groove 35 is provided on the side wall of the fixing rod 25; a guide block 34 is fixedly attached to the side wall of the second arc-shaped plate 31, and the guide block 34 is slidably connected to the inner wall of the guide groove 35; during operation, since the magnetic strips 33 are distributed on both sides of the arc-shaped through groove 3, when the annular plate 15 rotates, the magnetic strips 33 and the second arc-shaped plate 31 attract each other, which will drive the second arc-shaped plate 31 to move upward, thereby increasing the adhesion of the cleaning brush 32. At the same time, when the magnetic strips 33 and the second arc-shaped plate 31 are misaligned, the second arc-shaped plate 31 will suddenly move downward, with a sudden force, which can facilitate the self-cleaning operation of the cleaning brush 32.

[0054] The second arc-shaped plate 31 is provided with a set of discharge troughs 36, and the discharge troughs 36 and the cleaning brushes 32 are arranged alternately. During operation, the discharge troughs 36 can be used to collect impurities and drop them onto the first arc-shaped plate 24, which facilitates subsequent cleaning work.

[0055] The second arc-shaped plate 31, the first arc-shaped plate 24, and the annular plate 15 are arranged in parallel to each other. During operation, the cleaning brush 32 can easily clean the sponge layer 18 through the arc-shaped through groove 3, and the parallel arrangement of the three avoids the influence of movement interference.

[0056] Working principle: When the wound tube is initially pulled through the coating box 12 by the traction device, the motor 2 is started. The motor 2 drives the second rotating shaft 21 to rotate, which in turn drives the first gear 22 to rotate, which in turn drives the first annular rack 23 to rotate, which in turn drives the annular plate 15 to rotate. The rotation of the annular plate 15 causes the sponge layer 18 on the first rotating shaft 17 to rotate around the center line of the first through hole 13. The sponge layer 18 then wipes and cleans the surface of the wound tube, preventing the wound tube exposed to the external environment from being contaminated by impurities in the external factory environment during the traction process, which would affect the bonding of the coating material and the hot melt bonding effect in the subsequent coating box 12. At the same time, the sponge layer 18 rotates around the first rotating shaft 17, preventing the sponge layer 18 and the wound tube from being fixed in position for a long time, which would cause excessive local impurities on the sponge layer 18 and affect the cleaning effect. When the rotating shaft 17 rotates with the annular plate 15, the first arc-shaped plate 24 and the fixed rod 25 are both in a fixed state, which also fixes the second annular rack 26. Then, through the meshing of the second gear 27 and the second annular rack 26, the first rotating shaft 17 rotates while following the annular plate 15, which facilitates the rolling of the sponge layer 18, making it easier for impurities to fall off and effectively preventing the accumulation of impurities from affecting the wiping and cleaning effect of the sponge layer 18. Since the magnetic strip 33 is distributed on both sides of the arc-shaped through groove 3, when the annular plate 15 rotates, the magnetic strip 33 and the second arc-shaped plate 31 attract each other, which will drive the second arc-shaped plate 31 to move upward, thereby increasing the adhesion of the cleaning brush 32. At the same time, when the magnetic strip 33 and the second arc-shaped plate 31 are misaligned, the second arc-shaped plate 31 will suddenly move downward, which has a sudden force and facilitates the self-cleaning operation of the cleaning brush 32.
